Description

  The present invention relates to a separation plate for separating an operating room into a clean field and an unclean field, and is used particularly when blood or a chemical solution is required to flow between the clean field and an unclean field. The present invention relates to an operating room separation plate suitable for the above.

For example, extracorporeal circulation is performed during open heart surgery. In that case, in addition to the pump as an artificial heart-lung machine, various devices such as chemical pumps or blood suction pumps, artificial lungs, and heat exchangers are installed in the operating room. Since such devices cannot be completely sterilized, the device installation area in the operating room is left as an unclean field. On the other hand, the patient side region in the same operating room, that is, the region where the operation is performed (hereinafter referred to as “operating field”) is completely sterilized to be a clean field. Therefore, the surgeons in the clean field must not touch the equipment on the unclean field side. However, in the extracorporeal circulation, the blood circuit connecting the cardiopulmonary apparatus and the patient is set to the minimum necessary length in order to reduce the blood filling amount as much as possible. For this reason, the clean field and the unclean field are brought close to each other, and it is difficult to maintain the clean field. For this reason, it is necessary to separate the operating room into a clean field and an unclean field during surgery using equipment such as an extracorporeal circulation device.
In general, a transparent resin sheet such as PVC (vinyl chloride resin) is used as a separating means for separating the operating room into a clean field and an unclean field. The sheet is used in a state of being suspended in a curtain shape.

  By the way, at the time of extracorporeal circulation, it is necessary to connect the patient and devices by a circuit such as an extracorporeal circulation circuit, and to circulate blood and drug solution therebetween. That is, it is required to distribute blood and chemicals between the clean field and the unclean field. In such a case, if a single sheet is used as a separating means for separating the operating room into a clean field and an unclean field, the sheet may block the patient and the equipment. Therefore, it is necessary to circulate blood and chemicals so as to bypass the sheet. For example, in order to perform extracorporeal circulation, it is necessary to arrange a circuit for connecting a patient and devices so as to pass outside the periphery of the seat. Therefore, the circuit becomes long. On the other hand, as described above, recently, it has become necessary to shorten the extracorporeal circuit as much as possible in order to reduce the priming amount of blood or drug solution to be initially filled during surgery using the extracorporeal circulation. Yes.

For this reason, a sheet provided with an opening at a predetermined position is used as a separating means for separating the operating room where extracorporeal circulation use surgery is performed into a clean field and an unclean field, and the extracorporeal circuit is passed through the opening. In order to shorten the extracorporeal circulation circuit between the clean field and the unclean field by penetrating the path, it has been proposed (see, for example, Patent Document 1 and Patent Document 2).

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows an embodiment of the operating room separator according to the present invention, FIG. 1 is a longitudinal side view showing the operating state of the separator, and FIG. 2 is a front view of the separator as seen from the clean field side. It is.

  The separation plate 1 of this embodiment is used to separate the operating room into a clean field and an unclean field during an operation using extracorporeal circulation. In the operating room, one side (left side in FIG. 1) is an unclean field where an extracorporeal circulation device 2 incorporating a plurality of roller pumps, artificial lungs, heat exchangers, and the like is installed, and the other side (FIG. 1). The right side) is regarded as a clean field as a surgical field where surgery is performed.

  As apparent from FIGS. 1 and 2, the separation plate 1 is formed by connecting a plurality of plate-like cells 4, 4,... The cell 4 is a basic unit constituting the separation plate 1 and is made of a transparent rectangular thin plate made of a soft resin such as PVC or polyethylene. In a state in which the cells 4 are connected, the separation plate 1 has a single plate shape having a larger area than each cell 4.

  The separation plate 1 of the present invention is configured by connecting a required number of cells 4 in the vertical and horizontal directions according to the dimensions and shape of the operating room, the arrangement of the extracorporeal circulation device 2, and the like. 1 and 2, as an example, the separation plate 1 is composed of 20 (5 rows × 4 columns) cells 4, 4,..., And the uppermost cells 4, 4,. It is slidably suspended from

  As shown in the figure, the plurality of cells 4, 4,... Include a cell in which a plurality of openings 5 having a predetermined diameter are formed and a cell having no such opening. The separation plate 1 of the present invention includes at least one cell in which such an opening 5 is formed. The tube 9 of the extracorporeal circuit is penetrated through one or more of the openings 5 of the cell 4. In that case, preferably, a tube holder (see FIG. 7) described later is attached to hold the tube. Alternatively, a tube connection connector (see FIG. 12), which will be described later, is mounted so that the tubes can be interconnected from both sides of the separation plate 1. The opening 5 in which neither the tube holder nor the connector needs to be mounted is closed by a lid (see FIG. 14) described later.

  In addition, arrangement | positioning of cell 4,4 ... is not limited to the aspect to show in figure, Considering the positional relationship of a patient and the extracorporeal circulation apparatus 2, etc., it arrange | positions so that the opening 5 may be located in a desired position. At that time, since the adjacent cells 4 and 4 are detachably connected to each other, they are rearranged as necessary, and the arrangement thereof is changed as appropriate.

Next, based on FIG.3 and FIG.4, the connection structure of cell 4,4 ... which comprises the separating plate 1 is demonstrated.
3A is an enlarged vertical side view showing a connecting member for connecting adjacent cells 4 and 4, and FIG. 3B is an enlarged vertical side view showing a state in which the cells 4 and 4 in the connected state are folded. FIG. FIG. 4 is a top view of the separation plate 1 shown in FIG. 2 and shows a state in which it is slid along the guide rail 11 and folded.

  As shown in FIG. 3A, adjacent cells 4 and 4 are connected to each other by a detachable connecting member 21. The connecting member 21 is composed of holding portions 22 and 22 at both ends for detachably holding the edge portion of the cell 4 and a plate-like connecting portion 23 for connecting the holding portions 22 and 22 to each other. The connecting portion 23 is made of a flexible material, and the connected cells 4 and 4 can be folded by bending the connecting portion 23 as shown in FIG. Therefore, for example, in the case of the separation plate 1 shown in FIG. 2, it is possible to fold the whole separation plate and collect it compactly as shown in FIG. 4 while being suspended like a curtain.

  In addition, the connection member for connecting adjacent cells 4 and 4 so that folding is possible is not limited to what is shown in FIG. 3, For example, the O-ring 26 as shown to Fig.5 (a) may be sufficient, Moreover, the S-shaped hook 27 as shown in FIG.5 (b) may be sufficient, or the flexible sheet-like member 28 as shown in FIG.5 (c) may be sufficient. Instead of the connecting member described above, the cell 4 itself may be integrally provided with a hook-like connecting structure 29 as shown in FIG.

In this way, according to the operating room separation plate 1 described above, the plurality of cells 4, 4,... Are detachably connected to each other, so that an opening 5 is formed among the cells 4, 4,. It is possible to change the arrangement position of the cell 4 that has been set. Then, blood and chemicals can be circulated through the opening 5. Accordingly, the position of the opening 5 provided on the separating plate 1 for separating the operating room into a clean field and an unclean field and for circulating blood and chemicals between the clean field and the unclean field is designated as a patient or device in the operating room. It can be set appropriately according to the arrangement of the class.
In addition, each cell 4 has a much smaller area than the entire separation plate 1, so that sterilization processing and handling during transportation are facilitated. Since each cell 4 itself can have the same shape, its manufacture is easy and it can be obtained at low cost.

  Further, since the separation plate 1 is configured to be foldable, the separation plate 1 can be compactly gathered when not needed, and can be deployed only when necessary to partition the operating room. Therefore, even when the devices are moved before and after the operation, the separation plate 1 does not hinder the work.

Next, the tube holder provided in the opening 5 of the cell 4 will be described with reference to FIGS.
Fig.6 (a) is a front view of a tube holder, FIG.6 (b) is sectional drawing which follows the AA line of (a). Moreover, Fig.7 (a) is a front view of the state which mounted | wore the opening 5 of the cell 4 with the tube holder of FIG. 6, FIG.7 (b) is sectional drawing which follows the BB line of (a). And Fig.8 (a) is a vertical side view which shows the usage example of a tube holder, FIG.8 (b) is a vertical side view which shows another usage example.

  The tube holder 30 is used to hold a tube penetrating the opening 5 of the cell 4 and is detachably attached to the opening 5. As shown in FIG. 6, the tube holder 30 includes a holding tube 32 that holds the tube inside, and a fixing portion 33 that fixes the holding tube 32 to the cell 4. The tube holder 30 having the above configuration is formed of an elastically deformable resin and is integrally molded.

The inner diameter of the holding tube 32 is slightly smaller than the outer diameter of the tube used in the extracorporeal circuit or the like. Therefore, the tube holder 30 can hold the tube in an inscribed state so that the tube does not move relatively.
Three fixing portions 33 are provided at equiangular intervals at the outer peripheral end of the holding tube 32. Each fixing portion 33 includes an arm 34 and a latch 35. As shown in FIG. 6A, the arm 34 projects radially from the outer peripheral end of the holding tube 32. As shown in FIG. 6B, the latch 35 is erected between the base end and the distal end of the arm 34, and extends in a direction parallel to and away from the holding tube 32. An engaging claw 36 that can engage with the peripheral edge of the opening 5 of the cell 4 is provided at the tip of the latch 35. A recess 37 is formed between the distal end side of the arm 34 and the engaging claw 36, and the periphery of the opening 5 can be fitted into the recess 37.

  When the tube holder 30 is attached to the opening 5 of the cell 4, the tapered surface of the engaging claw 36 is pressed against the periphery of the opening 5 and the holding tube 32 is pushed in. Then, all the fixing parts 33 are elastically deformed in the centripetal direction with the pushing. When further pushed in and the engaging claw 36 protrudes beyond the opening 5 to the opposite side of the cell 4, the fixing portion 33 returns to the original shape, and the periphery of the opening 5 is fitted into the recess 37, as shown in FIG. To the state. In this state, the engaging claw 36 of the fixing portion 33 engages with the peripheral edge of the opening 5 of the cell 4.

  When the mounting of the tube holder 30 is completed, the holding tube 32 is fixed at a position facing the opening 5 as shown in FIG. Then, as shown in FIG. 7B, the periphery of the opening 5 is fitted into the recess 37 between the arm 34 and the engaging claw 36, so that the dropout from the opening 5 is reliably prevented.

  In addition, the width of the concave portion 37 of the fixing portion 33 may be wider than the thickness of the cell 4 so that the tube holder 30 can rotate relative to the cell 4. By doing so, even if the tube is twisted at the time of tube connection or surgery, the twist can be automatically eliminated.

A specific use example of the tube holder 30 described above is shown in FIG.
When using the tube holder 30, first, the tube 8 on the operator side (clean field side) is fitted and inserted into the holding tube 32 of the tube holder 30, and the tube 8 is moved to the holding tube 32 at an arbitrary position. Keep it impossible. Next, a tube connecting connector 13 is prepared, and one end thereof is pushed into the distal end opening of the held tube 8 and connected as shown in the figure. Subsequently, in consideration of the positional relationship between the patient and the extracorporeal circulation device 2 or the like, the opening 5 at the most suitable position for passing the tube 8 is determined. Then, the connector 13 is passed through the opening 5 from the clean field side as shown in the figure, and the tube holder 30 is attached to the opening 5 from the clean field side and fixed to the cell 4. Subsequently, the tube 9 from the extracorporeal circulation device 2 is connected to the other end of the connector 13 that has come out to the unclean field side of the cell 4.
In addition, although the case where the tube holder 30 was mounted | worn from the clean field side was demonstrated in the usage example mentioned above, it can also be mounted | worn from the unclean field side by making the tube holder 30 into a reverse direction.

  In a state where the tube holder 30 is attached to the opening 5 of the cell 4, the tube 8 is held immovably by the holding tube 32. Therefore, even if the surgeon or the like pulls the tube 8 on the clean field side, the tube 9 on the clean field side does not move to the clean field side, so there is no possibility that the clean field side is contaminated.

  When removing the tube holder 30 from the opening 5, first the tube 9 on the unclean field side is removed from the connector 13. Next, the holding tube 32 is pressed and elastically deformed in the vicinity of the base of the arm 34 so that the engaging claw 36 is separated from the peripheral edge of the opening 5. At the same time, the tube holder 30 can be pulled out from the opening 5 by pulling it from the clean field side.

Another example of use of the tube holder 30 is shown in FIG.
In the example of use of the tube holder 30 shown in the figure, first, the tube 8 on the operator side (clean field side) is fitted into the holding tube 32 of the tube holder 30, and the tube 8 is held by the holding tube 32. Let Next, as shown in the figure, the tube 8 is passed through the opening 5 from the clean field side, and the tube holder 30 is attached to the opening 5 from the clean field and fixed to the cell 4. Subsequently, in this state, the tube 9 from the extracorporeal circulation device 2 is connected via the connector 13 to the tube 8 that has come out from the opposite side (the unclean field side) of the cell 4.

  As described above, according to the present embodiment, since the tube holder 30 that holds the tube 8 that penetrates between both surfaces of the cell 4 through the opening 5 is provided, for example, during the extracorporeal circulation, the clean field and the unclean field It is possible to stably support the tubes 8 and 9 for circulating blood and chemicals between them at any opening position. Therefore, the arrangement of the extracorporeal circuit is facilitated.

Next, a modified example of the tube holder will be described.
The tube holder which constitutes a part of the present invention is not limited to the above-described form, and for example, a modification described later can be adopted. Fig.9 (a) is a front view which shows the tube holder which concerns on a 1st modification, FIG.9 (b) is sectional drawing which follows the CC line | wire of (a).

  The tube holder 31 according to the first modification is different from the holding tube 32 shown in FIG. 6 in the configuration of the holding tube 38 that holds the tube. The holding tube (clip) 38 is integrally formed with a fixing portion 33 and is made of an elastically deformable resin. The holding tube 38 is a tube having a C-shaped cross section, and a gap 39 is formed along the axial direction. The inner diameter of the holding tube 38 is designed to be slightly smaller than the outer diameter of the holding tube. The holding tube 38 having such a configuration functions as a clip (grip pipe) that holds the tube as a whole.

  When the holding tube 38 holds the tube, the tube is pressed against the outer periphery of the holding tube 38 along the gap 39. When the tube is pushed in against the elastic force of the holding tube 38, the holding tube 38 is elastically deformed and the gap 39 is expanded. When the tube is pushed in continuously, the tube can be placed inside the holding tube 38 beyond the gap 39. In the state where the tube is accommodated in the holding tube 38, the outer diameter of the tube is larger than the inner diameter of the holding tube 38, so that the grip force (restoration due to elastic deformation) is applied to the tube from the entire inner circumference of the holding tube 38. Force) acts. As a result, since the holding tube 38 is firmly fixed to the tube, the holding tube 38 does not fall out of the tube through the gap 39, and the unclean field side tube enters the clean field side. Nor. If necessary, the holding tube 38 covered with the tube can be tightened with a fastening band or the like.

  According to the tube holder 31 having the above-described features, the holding tube 38 functions as a detachable clip, so that the tube holder 31 can be directly covered and fixed at an arbitrary position of the tube. Therefore, when attaching to the tube, a complicated operation of sliding from the end of the tube to a predetermined position becomes unnecessary, and a similar sliding operation becomes unnecessary when removing the tube. As a result, the tube holder can be attached and detached easily and quickly at the start and end of work. In addition, since the holding tube 38 is configured as a detachable clip that can be elastically deformed, the range of tube sizes that can be held is expanded, so that the convenience of the tube holder 31 can be enhanced.

Next, a second modification of the tube holder will be described.
Fig.10 (a) is a front view which shows the tube holder which concerns on a 2nd modification, FIG.10 (b) is sectional drawing which follows the DD line | wire of (a).

  The tube holder 40 according to the second modification is different from the fixing unit 33 shown in FIG. 6 in the configuration of the fixing unit 43. The fixing portion 43 includes a flange 44 provided at one end of the holding tube 32 and a latch 45 provided integrally with the flange 44. The flange 44 has an outer diameter that exceeds the diameter of the opening 5 of the cell 4. The latch 45 is erected on the flange 44 and extends in a direction parallel to and away from the holding tube 32. An engaging claw 46 that can engage with the periphery of the opening 5 is provided at the tip of the latch 45.

  In a state where the tube holder 40 is attached to the opening 5, the opening 5 is shielded by the flange 44 around the holding tube 32. That is, the flange 44 also functions as a lid in a state where it is attached to the opening 5. Therefore, the opening 5 is totally shielded by the holding tube 32 and the flange 44 that hold the tube, and the clean field can be prevented from being contaminated through the periphery of the holding tube 32.

Next, a third modification of the tube holder will be described.
Fig.11 (a) is a front view which shows the tube holder which concerns on a 3rd modification, FIG.11 (b) is sectional drawing which follows the EE line | wire of (a).

The tube holder 41 according to the third modification differs from the second modification shown in FIG. 10 in terms of the holding tube 38 and the flange 47 that hold the tube.
The holding tube (clip) 38 is integrally formed with a fixing portion 43 and is made of an elastically deformable resin. The holding tube 38 is a tube having a C-shaped cross section, and a gap 39 is formed along the axial direction. The inner diameter of the holding tube 38 is designed to be slightly smaller than the outer diameter of the holding tube. A flange 47 is provided at the end of the holding tube 38 as in the second modification shown in FIG. The flange 47 is formed with a fan-shaped notch 48 that communicates with the gap 39.

  According to the tube holder 41 having the above-described characteristics, the holding tube 38 functions as a detachable clip as in the first modification shown in FIG. Can be covered and fixed. Therefore, the effect that the tube holder can be attached and detached easily and quickly at the start and end of work is achieved.

Next, the connector provided in the opening 5 of the cell 4 will be described with reference to FIG.
FIG. 12 is a vertical side view of the connector.

  The connector 50 is used to interconnect the clean field side tube 8 and the unclean field side tube 9 and is detachably attached to the opening 5 of the cell 4. The connector 50 is formed of resin and includes a connection member 51 for connecting a tube and a holding member 54 for holding the connection member 51 in a rotatable manner.

  The connecting member 51 is formed in a substantially cylindrical shape, and tubes 8 and 9 are connected to both ends thereof from the clean field side and the unclean field side, respectively. A plurality of annular step portions 52 and 53 for preventing the connected tubes 8 and 9 from coming off are formed on the outer peripheral surfaces of both ends of the connection member 51, respectively. In a state where the tubes 8 and 9 are connected to both ends of the connection member 51, it is possible to circulate blood or drug solution through the connection member 51.

  The holding member 54 has the same shape as the tube holder 30 shown in FIG. 6, and includes a support tube 55 that supports the connection member 51 and a fixing portion 56 that fixes the support tube 55 to the cell 4. Have. The inner diameter of the support tube 55 is slightly larger than the outer diameter of the straight tubular portion provided between the step portions 52 and 53 at both ends of the connection member 51. Therefore, the support tube 55 can rotatably support the connection member 51. The fixing portion 56 is provided on the outer peripheral surface of the end portion of the support tube 55, and includes an arm 57 and a latch 58 similarly to the fixing portion 33 of the tube holder 30 shown in FIG.

  In using the connector 50 described above, first, the tube 8 on the operator side (clean field side) is connected to one end of the connection member 51. Next, in consideration of the positional relationship between the patient and the extracorporeal circulation device 2 and the like, the opening 5 at the position most suitable for the interconnection of the tubes is determined. Subsequently, the other end side of the connecting member 51 is passed through the predetermined opening 5 from the clean field side, and the connector 50 is attached to the opening 5 from the clean field side and fixed to the cell 4. In this state, the tube 9 on the extracorporeal circulation device 2 side is connected to the other end of the connection member 51 protruding from the unclean field side of the cell 4. Through the above procedure, the mounting of the connector 50 and the interconnection of the tubes 8 and 9 are completed.

  Note that the stepped portions 52 and 53 of the connection member 51 come into contact with both ends of the support tube 55, so that the connection member 51 does not fall out of the support tube 55. Further, the tubes 8 and 9 connected to the connection member 51 are firmly held by the step portions 52 and 53. Therefore, even if the tube 8 is pulled by an operator or the like, the tube 9 on the unclean field side does not move beyond the opening 5 to the clean field side, and the clean field side is contaminated by the tube 9 on the unclean field side. There is no.

  When removing the connector 50 from the opening 5 of the cell 4, first the tube 9 on the unclean field side is removed from the connection member 51. Next, the support tube 55 is pressed and elastically deformed near the base of the arm 57 so that the latch 58 is separated from the periphery of the opening 5.
