Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dissection table and chair device, a dissection system, and a method for preventing the diffusion of harmful gases.
More specifically, in performing dissection, dissection of harmful gas generated from the anatomical body to be dissected is prevented, so that the dissection operation can be performed safely without impairing the worker's health. The present invention relates to a platform, a dissection system, and a method for preventing diffusion of harmful gases.
Also, the present invention relates to a chair device having a function of a reading table, which does not hinder dissection work, furthermore, improves stability and prevents overturning.
[0002]
[Prior art]
Systematic anatomy, which is one of the anatomical training of medical students, is performed while systematically observing various parts of the whole body such as blood vessels, nerves, muscles, and organs. Usually, the anatomy training is performed continuously for a long period of several months, in parallel with the lecture. Therefore, the corpse (also referred to as a corpse or a specimen) is stored in a state of being placed on an autopsy table for several months until the anatomy training is completed.
[0003]
In general, anatomy training is performed by sequentially dissecting and observing in accordance with the training textbook. Specifically, about 20 to 40 dissection tables are arranged in the dissection training room, and several medical students form a group and dissect one corpse placed on each dissection table. Also, since the training is long, there is usually a round chair without a backrest around the dissection table so as not to disturb the dissection work.
[0004]
In addition, the training texts are usually kept together on a desk remote from the dissection table so that they do not interfere with the dissection work, and medical students sometimes leave the dissection table and look at the text. I'm going to go.
[0005]
[Problems to be solved by the invention]
By the way, after the anatomical training on that day, the body is usually covered with a vinyl cover to prevent it from drying out. However, since the corpse is not stored in a completely sealed state, formalin used as a preservative continuously evaporates spontaneously from the corpse. Therefore, the training room is filled with formalin gas the next day.
[0006]
As is well known, formalin is considerably toxic to the human body and has a strong protein clotting effect. For this reason, it invades the skin and mucous membranes, and causes pharyngitis and bronchitis depending on the inhalation of gas.
[0007]
The causative substance of sick house syndrome, which has been regarded as a problem in recent years, is formaldehyde, which is a component of formalin, and many students excessively react with this formalin gas to cause an allergic reaction.
Furthermore, harmful substances generated from the remains are not only formalin, but also airborne infection of bacteria spreading from the bodies is a problem.
[0008]
Under the circumstances described above, it has been desired to provide a training environment in which the trainee can safely perform the anatomy training without impairing the health.
[0009]
Also, as mentioned above, during the dissection work, you may check the training text, but since the text is placed away from the dissection table so as not to interfere with the dissection work, each time The disadvantage was that medical students had to go away and watched, and medical students were not able to concentrate on dissection training.
[0010]
Therefore, the present inventor has started to develop a reading table for the dissection table in order to eliminate the trouble of going to the text from the dissection table. However, since the dissection operation proceeds while surrounding the dissection table by several persons, directly attaching the reading table to the dissection table hinders the dissection operation. Also, if the text is placed too close to the dissection table, body fluids, blood, etc. may adhere, which is a hygienic problem.
[0011]
In addition, it is conceivable to place a self-sustaining reading table slightly away from the dissecting table.However, in the dissection training room, dozens or more than 100 medical students will receive training at the same time. If the lectern is placed in a limited space, there is a risk of falling due to contact or the like.
[0012]
Therefore, the present inventor further conducted intensive research and development on the dissecting lectern, and as a result, the chair arranged around the dissecting table has the function of the lectern, so that the lectern can be moved from the dissecting table. We succeeded in developing a new chair device that can be set up a little apart, does not hinder the dissection operation, and improves the stability of the lectern and prevents it from overturning, and completed the present invention.
[0013]

[0028]
Although the cover member can cover the processing section to be dissected in an essentially closed state, the “closed state” does not necessarily have to be a closed state in a strict sense, and is covered with a cover member. What is necessary is just to be in the state where the inside air does not easily leak to the outside air.
[0029]
Articles to be placed on the mounting table of the chair apparatus are not limited to books and other books, but may include notebooks, notebook computers, dissecting instruments such as scalpels and scissors, but are not particularly limited thereto.
[0030]
In the chair device, the chair and the mounting table may be directly connected by the connecting portion, or may be indirectly connected.
In the case of indirect connection, one end of the connection portion can be connected to a chair, and the other end can be connected to a support portion that supports the mounting table.
[0031]
(Operation)
The operation of the dissection table according to the present invention will be described.
When the anatomical body is placed on the anatomical table main body, the cover member provided on the anatomical table main body is turned to the upper side of the anatomical table main body to cover the anatomical body so that the anatomical body does not substantially come into contact with the outside air. . Thereby, diffusion (evaporation) of a harmful gas such as formalin gas generated from the anatomical body can be suppressed, and airborne infection of bacteria diffusing from the anatomical body can be prevented.
[0032]
In addition, a device provided with a means for purifying the internal air covered with the cover member or a means for reducing or removing the harmful gas inside the cover member is more effectively prevented from diffusing the harmful gas generated from the anatomy. Can be prevented.
[0033]
Further, at the time of dissection, the cover member covering the anatomical body is rotated and stored at the lower side of the dissection table main body. As described above, since the cover member can be folded and stored at the time of dissection, the cover member does not hinder the dissection operation.
[0034]
Further, if the air inside the cover covered with the cover member is purified while being circulated, or the harmful gas inside the cover covered with the cover member is reduced or removed while being circulated, the internal air or harmful gas can be removed at one time. It is possible to reliably purify harmful gases to a safe level by purifying them while repeatedly circulating them. Therefore, even if the cover member is actually opened and the dissection operation is started, there is no possibility that the operator will inhale a large amount of harmful gas in a short time.
[0035]
Next, the operation of the chair device according to the present invention will be described.
The chair device is usually set slightly away from the dissection table so as not to disturb the dissection operation, like a normal chair. Therefore, unlike the case where the mounting table is directly installed on the dissection table, it is difficult to disturb the dissection operation, and the dissection operation can be performed safely.
[0036]
The mounting table for placing books etc. is directly or indirectly connected to the chair by the connecting part, so that the distance between the chair and the mounting table can be adjusted, so that it is at the optimal position that does not interfere with the dissection work The mounting table can be moved.
[0037]
The mounting table is supported by a support to improve stability. In addition, as described above, since the mounting table is directly or indirectly connected to the chair by the connecting portion, there is no danger that the mounting table will fall even if it receives some external force.
[0038]
In the case where the mounting table is supported by the columns, the safety is high because no extra member is provided for the operator to catch the foot. In addition, since the casters are provided at the lower end of the column, the position of the column, that is, the position of the mounting table with respect to the chair can be easily changed with a light operating force.
[0039]
An apparatus having an adjusting means capable of adjusting the angle and height of the mounting table can be adjusted to a position where the mounted books and the like can be easily viewed.
[0040]
The connecting portion is configured to be rotatable in the circumferential direction around the chair, and the configuration in which the position of the mounting table with respect to the chair in the circumferential direction can be changed does not particularly change the position of the chair. In addition, the mounting table can be adjusted to an optimum position so as not to disturb the dissection operation.
[0041]

[0051]
The air blowing part 6 is provided on the underside of the placed anatomical body 2 (the left side in FIG. 3, the other short side of the base 32). The air blowing section 6 is formed in the same or substantially the same shape (hollow, trapezoidal in section) as the above-described air suction section 5b.
[0052]
The air inside (processing unit 31) covered by each of the cover members 3a, 3b is sucked from the air suction units 5a, 5a, 5b (each suction port 51a described later), passes through a suction path described later, and flows into the base unit 32. It is sent to the air purification device 4 provided below (slightly leftward in FIG. 1). Then, the air purified by the air purification device 4 is returned from the air blowing unit 6 to the processing unit 31 again through a delivery path described later.
[0053]
As shown in FIG. 3, a plurality of slit-shaped suction ports 51a are provided at required intervals on the upper surface of each air suction section 5a. Each suction port 51a is provided obliquely upward.
[0054]
The suction port 51a of each air suction section 5a is configured to be openable and closable by a slide type (rubbing type) closing plate (not shown). The closing plate is provided at three places along the longitudinal direction of the base section 32 for each air suction section 5a so that the suction port 51a can be opened and closed at each position. Reference numeral 52 denotes a knob used when sliding each closing plate. Since the opening and closing mechanism is a well-known technique, a detailed description is omitted.
[0055]
The outer surface portions 53, 53, 53 (see FIG. 3) of the air suction portion 5b are respectively inclined downward and outward. A number of slit-shaped suction ports 51b are provided at required intervals on the inner surface side of the air suction section 5b. Each suction port 51b is provided obliquely upward. Similarly, the suction port 51b is also configured to be openable and closable by a slide-type closing plate (not shown). Reference numeral 52 indicates a knob used when sliding the closing plate.
[0056]
As shown in FIG. 1, each air suction part 5a and air suction part 5b are indirectly connected to a suction pipe 82 having a rectangular cross section (see FIG. 1). One end of the suction pipe 82 is connected to the air purification device 4 via a flexible hose 81.
[0057]
As shown in FIG. 1, the suction pipe 82 and each of the air suction sections 5 a are connected to a rectangular connection pipe 822 provided on the upper side near one end of the suction pipe 82 (the connection pipe 822 on the back side is hidden and invisible. ) Are indirectly linked.
[0058]
The other end of the suction pipe 82 and the air suction part 5b are indirectly connected via an air duct 50b. Specifically, the lower side of the air suction part 5b communicates with an air duct 50b (see FIG. 4) provided along the short side of the base part 32 (the head side of the anatomical body 2). As shown in FIGS. 1 and 4, the air duct 50b and the other end (the right end in FIG. 1) of the suction pipe 82 are connected by a square connection port 821 (see FIG. 4).
[0059]
The air duct 50b, the suction pipe 82, and the flexible hose 81 form a suction path through which air is suctioned from the air suction units 5a, 5a, 5b to the air purification device 4.
[0060]
The outer surface portions 62, 62, 62 (see FIG. 3) of the air blowing portion 6 are respectively inclined downward and outward. On the inner surface side of the air blowing section 6, a large number of slit-shaped outlets 61 are provided at required intervals. Each outlet 61 is provided obliquely upward. Similarly, the outlet 61 is also configured to be openable and closable by a slide-type closing plate (not shown). Reference numeral 611 indicates a knob used when sliding the closing plate.
[0061]
The lower side of the air blowing section 6 communicates with an air duct 60 provided along the short side of the base section 32 (foot side of the anatomical body 2), similarly to the air suction section 5b. The air duct 60 is connected to one end of the delivery pipes 92, 92, as shown in FIGS. The other ends of the delivery pipes 92, 92 are connected to the air purification device 4 via flexible hoses 91, 91. The flexible hoses 91, 91, the delivery pipes 92, 92, and the air duct 60 form a delivery path for sending air from the air purification device 4 to the air blowing unit 6.
[0062]
Next, each of the cover members 3a and 3b will be described.
As shown in FIG. 1, the cover members 3 a are provided at two places (a total of four places) on each long side of the base 32. On the other hand, the cover member 3b is provided at one place (two places in total) on each short side of the base 32. Each of the cover members 3a, 3b has hinges 7, 7, 7, 7, 7 fixed on the long side and the short side (outside of the air suction portions 5a, 5a, 5b and the air blowing portion 6) over the entire length. Thus, it is provided on the dissection table main body 3 so as to be rotatable vertically.
[0063]
Each of the cover members 3a and 3b is formed of a plate-shaped plastic having a light shielding property. Specifically, each of the cover members 3a and 3b is made of polycarbonate having resistance to formalin gas and excellent in impact resistance, but is not particularly limited as long as it is a material having resistance to at least formalin gas. Absent.
[0064]
As shown in FIGS. 1 and 3 (in FIG. 3, an imaginary line), the cover members 3a and 3b have a shape capable of essentially covering the processing unit 31 without a gap by being combined above the base unit 32. ing. That is, each cover member 3a on the long side is formed in a trapezoidal shape as a whole, and the side edges where the cover members 3a are in contact with each other are formed linearly. The short side cover members 3b, 3b are formed in a triangular shape.
[0065]
In this embodiment, two cover members 3a, 3a (a total of four on both long sides) are provided on each long side of the base portion 32, but two cover members are provided. 3a, 3a can also be formed by one cover member. In this case, the number of long side cover members is two in total. Further, three or four or more cover members may be provided on one of the long sides (one side).
[0066]
The cover members 3a, 3a on the long sides facing each other with the base 32 interposed therebetween are fixed by stoppers 34, 34 (see FIG. 1) provided on the front end side of the outer surface.
[0067]
The assembled cover members 3a and 3b are supported by the outer surface portions 62 and 53 that are inclined downward below the air blowing portion 6 and the air suction portion 5b, and do not fall inward, as indicated by imaginary lines in FIG. The short-side cover members 3b, 3b are fitted into the side edges of the long-side cover members 3a, 3a that are combined facing each other, and are stably fixed.
[0068]
As shown in FIG. 1, the outer surface side of each cover member 3 a is formed of a magnetic iron plate at a required position on the front side (a corner on the front side in the present embodiment). The engaged receiving portion 71 is fixed. Further, as shown in FIG. 4, an engagement receiving portion 71 is similarly fixed to the front end side of the outer surface side of each cover member 3b. On the other hand, as shown in FIG. 1, a required number of permanent magnets 72 magnetically attached to the engagement receiving portions 71 are provided at required positions of the connecting portions 322 of the legs 33, 33.
[0069]
That is, when the fixing by the stoppers 34, 34 is released from the closed state shown in FIG. 1 and the cover members 3a, 3b are lowered (folded), the engagement receiving portions 71 of the cover members 3a, 3b become It is magnetically attached to the permanent magnet 72. As a result, the cover members 3a and 3b that have been lowered are fixed inside the dissection table main body 3, and do not expand outward by their own weight (they do not become vertical). Therefore, the cover members 3a and 3b do not disturb the trainee (operator) performing the dissection operation. Reference numeral 721 indicates an L-shaped bracket for fixing the permanent magnet 72 to the leg 33.
[0070]
Further, the air purification device 4 will be described.
The air purification device 4 is located slightly to the left below the base 32 in FIG. 1 and is fixedly provided on a mounting plate (reference numeral omitted) fixed to the connecting portion 322 of the leg 33. In the present embodiment, as the air purification device 4, a photocatalyst deodorizing device using titanium oxide (trade name “photocatalyst environmental purification device”, manufactured by Seiwa Kogyo Co., Ltd.) is used. There is no limitation.
[0071]
The air in the processing unit 31 is sent to the air purification device 4 from the air suction units 5a, 5a, 5b through the suction path. In the air sent to the air purification device 4, harmful gases such as formalin gas are adsorbed, decomposed, and deodorized by the photocatalyst. Thereafter, the purified air is sent back from the air blowing unit 6 into the processing unit 31 through the delivery path.
[0072]
At a required position on a side surface of the air purification device 4, an openable / closable discharge port 41 is provided. By opening and closing the discharge port 41, the amount of air circulated to the air purification device 4 can be adjusted. That is, when the discharge port 41 is closed, the air circulates through the air purification device 4, and when the discharge port 41 is fully opened, the air does not circulate and the outside of the dissection table 1 (outside air) is not circulated. ).
[0073]
Finally, other components constituting the dissection table 1 will be described.
As shown by the dotted line in FIG. 1, the bottom 320 of the platform 32 is slightly downwardly inclined toward the left side (under the feet of the anatomical body 2). Thereby, blood, bodily fluids, and the like are discharged from the drain port 321 on the surface of the base portion 32 by natural flow in FIG. The discharged blood or the like passes through a discharge duct 35 composed of a flexible hose and is stored in a pot 36 below the base 32. In FIG. 1, reference numeral 37 shown on the right side of the air purification device 4 is a box for temporarily storing bones and the like cut at the time of dissection.
[0074]
(Operation)
The operation of the dissection table 1 will be described with reference to the drawings, taking as an example the case where the operation of the dissection table 1 is used for anatomy training.
[0075]
Normally, since the dissection performed in the medical training lasts for a long period of several months, the anatomical body 2 is kept placed on the dissecting table 1 even after the anatomical training on that day is completed. The dissection 2 is stored as follows.
[0076]
In other words, the processing unit 31 for performing dissection is covered in a substantially sealed state by the respective cover members 3a and 3b shown in FIG. 1 (covering the dissected body 2 so as not to substantially contact the outside air).
[0077]
First, each cover member 3a on the long side is raised from the opened state shown in FIG. 2, and as shown in FIG. 4, the facing cover members 3a, 3a are assembled into a mountain shape and fixed with the stoppers 34, 34.
[0078]
Next, the cover members 3b, 3b on the short sides are similarly raised, leaned on both side surfaces of each of the cover members 3a formed in the shape of a mountain, and fixed. As described above, the short side cover members 3b, 3b are fitted into the side edges of the long side cover members 3a, 3a facing each other, and are stably fixed.
[0079]
As described above, by preventing the anatomical body 2 from being substantially in contact with the outside air, diffusion (evaporation) of harmful gas such as formalin gas generated from the anatomical body 2 is suppressed, and bacteria that diffuse from the anatomical body 2 are prevented. Air infection can be prevented.
[0080]
Further, according to the dissection table 1, the air can be purified while circulating the air (inside the processing unit 31) covered by the cover members 3a and 3b by the air cleaning device 4 below the base unit 32. Therefore, if the air purification device 4 is operated before the start of the training, the formalin gas in the processing unit 31 can be reduced or removed at the start of the training. Therefore, even if the training is started by actually opening the cover members 3a and 3b, there is no possibility that the trainee will inhale a large amount of formalin gas in a short time. Therefore, the health of the trainee is hardly adversely affected, and the anatomical training for a long period can be safely performed.
[0081]
Further, the air inside covered by the cover members 3a and 3b is repeatedly processed by the air purification device 4 while circulating, so that more reliable purification is possible.
[0082]
The air purification device 4 may be configured to operate automatically by a timer. With this configuration, the air purification device 4 is automatically operated before the training starts, and the formalin gas in the processing unit 31 can be removed before the training is actually performed.
[0083]
When actually performing dissection, the stoppers 34, 34 are removed and the cover members 3a, 3a, 3b, 3b are lowered. As a procedure for lowering, first, the cover members 3a, 3a, 3a, 3a on the long side are lowered, and then the cover members 3b, 3b on the short side are sequentially lowered.
[0084]
The lowered cover members 3a, 3b are fixed by permanent magnets 72,... Provided at required positions of the connecting portions 322 of the leg portions 33, so that the cover members 3a, 3b do not spread outside. As described above, since the cover members 3a and 3b can be folded down and accommodated, the cover members 3a and 3b do not interfere with the dissection operation.
[0085]
The air purification device 4 may be constantly operated during the dissection operation, or may be operated at regular intervals. By adjusting the degree of opening of the discharge port 41 on the side surface of the air purification device 4, part or all of the air purified by the air purification device 4 can be discharged indoors.
[0086]
When the anatomical training on that day is completed, the anatomical body 2 is covered again with the cover members 3a and 3b so that the anatomical body 2 does not substantially come into contact with the outside air. Further, in order to prevent the dissected body 2 from drying, a vinyl cover or the like may be directly hung on the dissected body 2, or a cover or the like may be indirectly hung on the cover members 3a and 3b.
[0087]
Although not shown, a handle that is convenient for opening and closing the cover members 3a and 3b can be attached to the front and back surfaces of the cover members 3a and 3b.
[0088]
Furthermore, after covering with the cover members 3a and 3b, the air purification device 4 may be operated for a required time. In this case, if a timer is used, the operation of the air purification device 4 can be automatically stopped.
The object of use of the dissecting table 1 is not limited to a human but may be an animal.

The chair device B forms a system for dissection in combination with the dissection table 1.
[0092]
As shown in FIG. 7, the chair device B includes a chair 20, a support 30 for supporting the mounting table 10 on which books and the like are mounted, and a connection between the chair 20 and the support 30, and adjusts the distance between the chair 20 and the support 30. It has a connecting part 40 that can be used.
Hereinafter, each component of the chair apparatus B will be described in detail in order.
[0093]
Please refer to FIG. 7 and FIG.
The chair 20 is provided with a seat 21 having a circular shape in plan view and a leg 22 mainly formed by combining a stainless steel bar.
[0094]
The leg portion 22 includes a plate-shaped base portion 221 (hereinafter, referred to as a substrate 221) having a circular shape in a plan view, a shaft foot portion 222, and a required number of foot portions 223 (five in this embodiment). The shaft foot 222 extends downward from the center of the lower surface of the substrate 221. Each leg 223 is provided to extend obliquely downward so as to extend outward from the inner edge of the substrate 221. Reference numeral 224 indicates an annular footrest.
[0095]
The annular footrest portion 224 is fixed to each foot portion 223 by a required number of foot connecting portions 225 (five in this embodiment) extending slightly obliquely downward toward the center. The feet 223 are connected to each other by the foot rest 224 and the foot connecting part 225. The foot portion 223 is located more inward (center side) than the footrest portion 224, and is designed so that an operator does not catch a foot on the foot portion 223.
[0096]
Due to its design, the shaft foot 222 is formed so that its diameter narrows in two steps downward from the substrate 221, and the diameter of the thinnest portion on the lower side is substantially the same as the diameter of the foot 223. The size has become.
[0097]
The seat portion 21 is rotatably supported by the shaft foot portion 222 by the shaft portion 220 so that the orientation of the body after sitting can be changed. The shaft portion 220 has a thread, and the shaft portion 220 moves up and down by rotating the seat portion 21 so that the height of the seat portion 21 can be adjusted.
[0098]
The column 30 supporting the mounting table 10 is mainly formed of a stainless steel pipe, and has a movable caster 50 at a lower end. The support column 30 has a nesting type at the front end side like a rod antenna and is extendable and retractable, so that the height of a book or the like placed on the mounting table 10 can be adjusted.
[0099]
More specifically, a column extending / contracting portion 302 is inserted and nested from an upper portion of a column main body 301 having a caster 50 at a lower end. The recesses 303,... Are provided at predetermined intervals in the height direction on the peripheral surface of the support column expandable portion 302. Bolt insertion holes (hidden in FIG. (Not visible). Then, in a state where the concave portion 303 of the column extending / contracting portion 302 and the bolt insertion hole of the column main body 301 are aligned, it is screwed and tightened with a fastener 305 provided with a bolt 304 to fix the column extending / contracting portion 302 and set the height. .
[0100]
The height adjustment mechanism of the column 30 is not particularly limited to this structure, and other well-known technologies (for example, an air cylinder or the like) can be adopted.
[0101]
The mounting table 10 is attached to the upper side of the column 30 (the column extending / contracting portion 302) so as to be tiltable with respect to the column 30 so that the placed books and the like can be easily viewed. The mounting table 10 has a rectangular shape in a plan view, and a bar-shaped stopper 101 that receives a mounted book or the like from below is provided along a long side of the plate body on the lower side (the left end side in FIG. 8) in FIG. It is provided.
[0102]
The angle adjusting mechanism of the mounting table 10 is as follows.
The strut extension portion 302 has an upper end portion formed in a flat shape in the diameter direction, and semicircular joint portions 102, 102 provided on a lower surface portion of the mounting table 10 are tiltably connected to the flat portion 302a. I have. The joints 102, 102 are juxtaposed at substantially the center of the lower surface of the mounting table 10 so as to sandwich the flat portion 302a from both sides.
[0103]
As shown in FIG. 7, a partially arc-shaped groove 103 is formed in each joint 102. A wing bolt 104 is provided through the groove 103 and the flat portion 302a. The bolt tip of the wing bolt 104 (hidden and invisible in the figure) is screwed into a bolt hole (hidden and invisible in the figure) provided in the joint 102 on the rear side in FIG. Then, the angle of the mounting table 10 with respect to the support column extending / contracting portion 302 can be fixed by turning and tightening the butterfly bolt 104 with a finger.
[0104]
Further, as described above, the chair 20 and the support 30 are connected by the connecting portion 40 so that the distance between the chair 20 and the support 30 can be adjusted. The connecting portion 40 is configured by joining arms 40 a and 40 b (two in this embodiment) via a shaft portion 401. The angle between the arms 40a and 40b in the horizontal direction can be adjusted to approximately 360 degrees (actually, within a range where the column 30 does not contact the chair 20).
[0105]
Therefore, by changing the angle between the arms 40a and 40b in the horizontal direction, the distance between the chair 20 and the support 30 can be adjusted within a certain range. Since the joining structure between the arms 40a and 40b is a well-known technique, a detailed description is omitted.
[0106]
One end side of the connecting portion 40 (arm 40 a) is fitted to the shaft portion 220 of the seat portion 20 via a joining portion 402 formed in a cylindrical shape, and the connecting portion 40 is circumferentially centered on the shaft portion 220. It is designed to rotate. The other end of the connecting portion 40 (arm 40b) is provided by being fixed to a substantially middle portion of the column 30 by welding.
[0107]
Further, when the connecting portion 40 rotates in the circumferential direction around the shaft portion 220, the arm 40a is slightly separated from the substrate 221 so that the arm 40a does not contact the substrate 221 of the leg portion 22. Fixed to.
[0108]
(Operation)
The operation of the chair device B will be described with reference to FIG.
FIG. 9 shows an example in which the dissection table 1 is used in combination with the dissection table 1 having the cover members 3a and 3b. However, the present invention is not particularly limited to this and is used in combination with a dissection table having another structure. It goes without saying that you can do it.
[0109]
In the present embodiment, a case where the chair apparatus B is used for anatomy training of a medical student will be described as an example.
[0110]
As shown in FIG. 9, when the chair apparatus B is used, the chair apparatus B is disposed slightly away from the dissection table 1 so as not to hinder the dissection operation. Similarly, the mounting table 10 is not located between the dissection table 1 and the chair 20, but the dissection table 1 as a front face as shown in FIG. Place on both sides.
[0111]
The connecting portion 40 connecting the columns 30 rotates in the circumferential direction around the shaft portion 220 of the chair 20, and the columns 30 are provided with casters 50. Therefore, if the connecting portion 40 is rotated while sitting on the chair 20, the position of the mounting table 10 with respect to the chair 20 in the circumferential direction can be easily changed with a small operation force.
[0112]
Moreover, the distance between the chair 20 and the support 30 can be freely adjusted within a certain range by bending or extending the connecting portion 40. Therefore, the mounting table 10 can be moved to an optimum position where the text can be easily viewed without disturbing the dissection operation. For example, if the column 30 is pulled toward the chair 20 from the position illustrated in FIG. 7 to the position illustrated in FIG. 9, the floor area occupied by the chair device B also becomes small, and does not hinder the dissection operation.
[0113]
Then, for example, the text T for dissection training is placed on the mounting table 10 in an open state, and the angle and height of the mounting table 10 are adjusted so that the text T is easily viewed. For example, if the height is adjusted as shown in FIG. 9, it is possible to check the text T while standing while performing the dissection work, as well as sitting down and viewing the text T.
[0114]
Thus, if the chair device B is used and placed nearby, unlike the related art, there is no need to go to the text T on the desk away from the dissection table 1, and the medical student can concentrate on the dissection training. .
[0115]
The mounting table 10 is supported from the ground surface by the columns 30. As shown in FIG. 8, below the mounting table 10, there are provided a foot member, a supporting member, and the like that protrude out of the frame of the mounting table 10. Not provided. In other words, even if the medical student passes beside the mounting table 10, there is no member that catches the foot, and the safety is high.
[0116]
In addition, since the foot 223 constituting the leg 22 of the chair 20 is located more inward than the footrest 224, there is no possibility that a medical student will get caught on the foot 223.
[0117]
The column 30 is provided at a distance from the chair 20 by the connecting portion 40. Therefore, in order for the support 30 to fall, an external force enough to simultaneously lower the chair 20 is required. Therefore, even if some external force is received, the support 30 does not fall. Moreover, since the casters 50 are provided on the support columns 30, even if a medical student accidentally hits the mounting table 10, the chairs 20 are stably standing just by moving the support columns 30 in the circumferential direction. Thus, the support 30 is prevented from falling down.
[0118]
In addition, as shown in FIG. 10, a structure in which the column 30 supporting the mounting table 10 is supported by four legs 30 a arranged in a cross shape (the rear leg 30 a is hidden and cannot be seen) may be employed. Alternatively, a structure in which three or five or more feet 30a are supported may be used. Each leg 30a shown in FIG. 10 is provided with a caster 50.
[0119]
If the support 30 has excellent stability and there is no danger of falling down, a chair as shown in FIG. 10 (a chair having the support 70 and four legs 70a arranged in a cross shape) is adopted. You can also. Further, although not shown, a caster can be attached to the chair, and a backrest can be provided.
Note that the leg 30a shown in FIG. 10 can be used as the support 30 of the chair device B shown in FIG. 7, and the support 70 and the foot 70a shown in FIG. 10 can be used as the chair 20 of the chair device B. it can.
[0120]
Although not shown, the connecting portion 40 is formed in an L-shape to directly connect the mounting table 10 and the chair 20, and furthermore, the support 30 is provided separately and independently from the connecting portion 40, and the connecting portion 40 and the support It is also possible to adopt a structure in which the mounting table 10 is supported by both of them.
[0121]
As described above, if the dissection table 1 and the chair device B according to the present embodiment are used, the dissection operation can be performed safely while concentrating on the anatomy training.
[0122]
The terms and expressions used in the present specification are illustrative only, not limiting, and do not exclude the terms, expressions, and equivalents. Further, the present invention is not limited to the illustrated embodiment, and various modifications are possible within the scope of the technical idea.
[0123]
【The invention's effect】
The present invention has the above configuration and has the following effects.
(A) According to the dissection table according to the present invention, the processing section is covered with the cover member in an essentially closed state (covers the dissection body so as not to substantially come into contact with the outside air), thereby generating from the dissection body. The diffusion of the harmful gas can be prevented. Thereby, when performing the dissection, the worker can safely perform the dissection operation without impairing the health.
[0124]
(B) If the cover member can be folded and stored at the time of dissection, or if the cover member rotated to the lower side of the dissection table main body is provided with means capable of fixing the cover member to the dissection table main body, It is convenient because it does not interfere with the dissection work.
[0125]
(C) In the apparatus provided with a means for purifying the air inside the cover member or a means for reducing or removing the harmful gas inside the cover member, the diffusion of the harmful gas generated from the anatomy can be more effectively performed. Safe and safe.
[0126]
(D) In the case of purifying while circulating the internal air covered by the cover member or reducing or removing the internal harmful gas while circulating the internal harmful gas, circulate the internal air or harmful gas not once but repeatedly. By purifying while harmful gases can be reliably purified to a safe level. Therefore, even if the cover member is actually opened and the dissection operation is started, there is no possibility that the operator will inhale a large amount of harmful gas in a short time.
[0127]
(E) According to the chair device of the present invention, the mounting table on which the books and the like are mounted is not provided on the dissection table, but is provided on a chair that is arranged separately and independently from the dissection table. Therefore, the mounting table can be arranged at a position slightly away from the dissection table. Therefore, unlike the case where the mounting table is directly installed on the dissection table, it is less likely to hinder the dissection operation. In addition, if the chair device is used, for example, for anatomical training, the medical student can concentrate on the anatomical training without having to leave the dissection table and look at the training text each time.
Further, the connecting portion connects the mounting table directly or indirectly to the chair so that the distance between the chair and the mounting table can be adjusted. Therefore, the mounting table can be moved to an optimal position that does not hinder the dissection operation, so that the dissection operation can be performed safely without any hindrance.
Further, the mounting table is supported by a support portion to improve stability. Moreover, as described above, the mounting table is connected to the chair by the connecting portion. Therefore, in order for the support portion to fall down, an external force enough to cause the chair to fall down at the same time is required, so that the mounting table does not fall down even if it receives some external force.
[0128]
(F) Since the mounting table is supported by the columns, there is no extra member for the operator to catch the foot, so that the safety is high. In addition, since the casters are provided at the lower end of the column, the position of the column, that is, the position of the mounting table with respect to the chair can be easily changed with a light operating force.
[0129]
(G) The one having the adjusting means capable of adjusting the angle and height of the mounting table can be adjusted to a position where a book or the like can be easily seen, so that the convenience is high. For example, if an adjustment is made so that a book or the like can be viewed while sitting or standing, the dissection work can be performed more concentratedly.
[0130]
(H) When the connecting portion is rotated in the circumferential direction about the chair so that the position of the mounting table with respect to the chair in the circumferential direction can be changed, the dissection operation can be performed without particularly changing the position of the chair. The mounting table can be adjusted to an optimum position so as not to disturb the user. In addition, when casters are provided on the support, even if the worker accidentally hits the mounting table, the caster simply moves in the circumferential direction, and the chair stably stands. Is prevented.
[0131]
(I) In the dissection system according to the present invention, which is a combination of the dissection table and the chair device, the dissection operation can be performed safely by the above-described effects.
[0132]
(J) According to the method for preventing harmful gas diffusion according to the present invention, the anatomical body to be dissected is covered so that it does not substantially come into contact with the outside air, and the harmful gas inside the covered anatomical body is reduced or removed. The diffusion of the harmful gas generated from the water can be prevented. Thereby, when performing the dissection, the worker can safely perform the dissection work without impairing the health.
