In the present embodiment, as an object to be cleaned, an explanation will be given of an olief in which a doctor inserts a tip into a patient's nostril and sucks nasal discharge or the like as an object to be cleaned. In addition, in this specification, the water used for the preliminary washing before using a detergent other than the water containing a detergent, and the water at the time of rinsing are called washing water.

  The cleaning device 1 has a transparent body 21a fitted in a device body 2 formed in a box shape having a height of about 320 mm, a width of about 730 mm, and a depth of about 500 mm, and a handle 21b formed in an inverted U shape is provided in front. The lid part 21 provided in the part is provided. The lid 21 is rotatably provided on the apparatus main body 2 via a hinge 21c.

  A door latch 22 is provided on the upper surface of the apparatus main body 2 to restrict the lid 21 from being closed when the lid 21 is opened. Further, a power switch 23 and a start button 24 for instructing start of cleaning are provided on the front surface of the apparatus main body 2.

  As shown in FIGS. 2 to 4, the apparatus main body 2 includes a stainless steel cleaning tank 3 for immersing the Olef P, which is a medical instrument having a pipeline, in the cleaning water.

  Connected to the upper part of one end of the cleaning tank 3 is a water supply pipe 31 to which RO (Reverse Osmosis) water, city water supplied from a general water supply, or hot water heated to a high temperature is supplied. ing. The water supply pipe 31 is provided with a water supply valve 32. Further, at the lower part of one end of the cleaning tank 3, a water discharge port 33 for the cleaning water circulating in the cleaning tank 3 is provided.

  A drain outlet 34 for discharging the cleaning water in the cleaning tank 3 is provided at the lower part of the other end of the cleaning tank 3. The drain pipe 34a connected to the drain port 34 is prevented from overflowing the washing tank 3 by draining the washing water when the level of the washing water in the washing tank 3 exceeds a predetermined level. An overflow 36 is connected. This liquid level is monitored by a liquid level monitoring device 4 (not shown in FIGS. 2 to 4). As shown in FIG. 5, the liquid level monitoring device 4 includes a level pipe 41 formed of a light transmissive member connected to a water intake 37 provided in the lower part of the cleaning tank 3, and a liquid in the level pipe 41. Liquid level sensors 42a and 42b for optically detecting the surface and notifying the controller 6 described later via a code 6a, and a partition plate 43 provided at the water intake 37 are provided.

  If bubbles of cleaning water enter the level pipe 41, the liquid level sensors 42a and 42b may be erroneously detected. Therefore, the partition plate 43 formed in the L-shaped cross section on the wall surface of the cleaning tank 3 is provided in front of the water outlet 37, and the gap between the bottom surface of the cleaning tank 3 that becomes a path for the bubble to enter is narrowed. , And the intrusion of bubbles into the level tube 41 can be suppressed.

As shown in FIGS. 2 to 4, a suction unit 35 in which a nozzle 35 b is provided in a suction pipe 35 a is provided at the lower part of the other end of the cleaning tank 3.
In the suction unit 35, six nozzles 35b are arranged in a row so that the suction port faces the center of the cleaning tank 3 along the axis of the suction pipe 35a. The nozzle 35b is a connection joint with a valve that functions to close the flow path when it is in an unconnected state.

A suction pump 5 that sucks cleaning water from a nozzle 35b is connected to the suction pipe 35a. The suction pump 5 circulates the cleaning water in the cleaning tank 3 by discharging the cleaning water sucked through the suction pipe 35 a from the water discharge port 33.
The bottom surface of the cleaning tank 3 is formed in an inclined surface that descends from one end where the water discharge port 33 is provided toward the other end where the drain port 34 is provided. Drainage from the drainage port 34 is controlled by a drainage valve 34b provided in the drainage pipe 34a.

  The suction pump 5 is controlled by the control device 6 to start and stop suction. The control device 6 has a function of controlling the opening / closing of the water supply valve 32 and the opening / closing of the drain valve 34b in addition to the control of the suction pump 5.

  The instrument connection adapter 7 is connected to the nozzle 35 b of the suction unit 35. The appliance connecting adapter 7 and the suction unit 35 constitute a suction part.

  As shown in FIGS. 2 and 6, the instrument connection adapter 7 includes an adapter main body 71, a connection pipe 72 that connects the orifice P to the adapter main body 71, and a connection tube 73 that connects the adapter main body 71 to the nozzle 35 b. ing.

  The adapter main body 71 includes seven water intake pipes 71a protruding from one surface side, two water discharge pipes 71b protruding from the other surface opposite to the one surface side, a water discharge pipe 71b, and a connection tube 73. It is a hollow stainless steel box provided with a main body side connector 71c to be connected.

  The connecting pipe 72 is a tube whose inner diameter and outer diameter do not change from one end side to the other end side, and is formed of a soft silicon tube so as to be in close contact with the outer peripheral surfaces of the water inlet pipe 71a and the olief P.

  The connection tube 73 is a water pipe having connectors formed at both ends of the tube in order to connect the main body side connector 71c and the connector of the nozzle 35b in a communicating state.

Here, the connection of the connection pipe 72 will be described in detail with reference to FIG.
As shown in FIG. 7, the leading connecting pipe 72 is fitted in a state where one end communicates with the water inlet pipe 71 a of the adapter main body 71. Since the water inlet pipe 71a is formed in a cylindrical shape, the entire outer peripheral surface of the water inlet pipe 71a can be brought into close contact with the inner peripheral surface of the connecting pipe 72 formed in the same cylindrical shape. The other end of the leading connecting pipe 72 is fitted with an orifice P1 that gradually decreases in diameter toward the distal end.

  The connecting pipe 72 is further fitted as a second fitting at the base end of the olief P1 connected to the connecting pipe 72 attached to the water inlet pipe 71a. In this way, the connecting pipe 72 and the olives P (P1 to P4) are alternately fitted, so that the olives P are connected in cascade like a daisy chain. That is, as shown in FIG. 2 and FIG. 6, four orifes P are connected to one inlet pipe 71a, so that 28 orifes P are connected to one instrument connection adapter 7. As a whole, 84 olives P are connected.

The use state of the cleaning apparatus 1 according to the embodiment of the present invention configured as described above will be described with reference to the drawings.
First, the operator connects three instrument connection adapters 7 connected to the two nozzles 35b. It is assumed that the connection pipe 72 is fitted into the water intake pipe 71a in the appliance connection adapter 7. When the connection of the instrument connection adapter 7 is completed, one end of the orifice P1 that needs cleaning is fitted into the connection pipe 72 and connected. Then, the connecting pipe 72 is fitted into the other end of the orifice P1, and then the orifice P2 is fitted. In this way, the connection between the olives P1 to P7 and the connecting pipe 72 is alternately repeated to connect the olives P1 to the olives P7 in a communicating state.

Next, the operator turns on the cleaning device 1 with the power switch 23 and presses the start button 24, whereby the control device 6 performs cleaning. The cleaning is started by first opening the water supply valve 32 by the control device 6 so that the cleaning water containing the chemical solution is supplied to a predetermined liquid level based on information from the liquid level monitoring device 4. When the water supply is completed, the suction pump 5 is operated to circulate the cleaning liquid. The suction of the suction pump 5 is transmitted to the instrument connection adapter 7 through the nozzle 35b of the suction unit 35. The appliance connection adapter 7 is connected to seven sets of four olives P1 to P4 that are connected in cascade as a set, so that washing water can be passed through the pipe line formed by the four olives P. Requires a considerable suction force. In the present embodiment, since the instrument connection adapter 7 uses the instrument connection adapter 7 connected to the two nozzles 35b, it is possible to ensure a suction force twice that of the instrument connection adapter 7 connected to the one nozzle 35b. . Therefore, even when a large number of the olives P are connected, it is possible to prevent the suction force from decreasing.
Further, since the bottom surface of the cleaning tank 3 is inclined so as to be lowered in the suction direction of the cleaning water, the cleaning water flowing in the olief P is sucked down so that the cleaning effect can be improved. it can.

  Washing by circulation is performed for 3 cycles, with a 2-minute operation and a 5-minute stop by the suction pump 5 as one cycle. This cycle is executed by programming the control device 6. Thus, as one cycle of washing, by providing a period during which the washing water flows and a period during which the washing water flows through the pipes of the olief P, deposits that cannot be removed are lifted during the period during which the washing water stays. Since the adhering substances floating during the period when the washing water flows can be discharged and removed, the detergency can be improved.

  When the cleaning by the circulation is completed, the control device 6 opens the drain port 34 and drains the cleaning water. The bottom surface of the washing tub 3 is formed on an inclined surface that descends from one end portion where the water discharge port 33 is provided toward the other end portion where the drain port 34 is provided, so that quick drainage is possible. It is.

  After draining, the control device 6 completes cleaning by rinsing and drying by suction. As described above, the cleaning apparatus 1 according to the present embodiment allows the cleaning water to sufficiently flow through the pipes in all the olives P by cascading a large number of the olives P that require cleaning through the connection pipe 72. Can do. Accordingly, even if the olives P are bulky if they are collected together, many olives P can be connected at a time, so that the olives P can be reliably washed. Therefore, a large number of olives P can be washed in a short time, and secondary infection can be prevented.

  Next, a connecting pipe according to another embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a view showing a connecting pipe according to another embodiment of the present invention, in which (A) is a perspective view and (B) is an exploded perspective view. FIG. 9 is a diagram showing another olief. FIG. 10 is a diagram illustrating an example of a connection pipe.

  As shown in FIG. 8, the connection pipe 8 is for cascade connection in a state where medical instruments such as an olief are communicated, and includes a first connection pipe (first connection portion) 81 and a second connection pipe ( The second connection part) 82 and the intermediate connection part 83 are formed.

  The first connecting pipe 81 and the second connecting pipe 82 have different inner diameters, but are formed of the same soft silicon tube. The intermediate connection portion 83 is made of hard polypropylene by cutting.

  If the medical device connected in cascade for cleaning is connected even if the opening diameter of the connecting pipe is the same on the one end side and the other end side across the connecting pipe, the inner diameter does not change A connecting pipe 72 can be employed. However, for example, in the case of an infant olief Px to be inserted into two nostrils as shown in FIG. 9, a connecting tube having a larger opening diameter is required. Therefore, for example, when the olives Px shown in FIG. 9 are cascade-connected to the olives P shown in FIG. 6, they can be easily connected by using the connecting pipe 8 shown in FIG.

  As the connecting pipe having an opening diameter on one end side larger than the opening diameter on the other end side, a tube (connecting pipe 9) whose inner diameter gradually decreases from one end side 9a toward the other end side 9b as shown in FIG. ) Is also possible. However, since the diameter of the other end 9b of the connecting tube 9 increases toward the back from the opening, the opening of the other end 9b is brought into contact with the outer peripheral surface of the medical instrument when the medical instrument is connected. Although it can be in a state, there is a possibility that a gap may be formed toward the back, and the degree of adhesion is low. Moreover, although it is possible to make the connecting tube 9 as an integrally molded product made of silicon tube, a great cost is required to manufacture the mold.

In the case of the connecting pipe 8 shown in FIG. 8, the first connecting pipe 81 and the second connecting pipe 82 are soft members whose inner diameters do not change. Therefore, when the medical instrument is inserted deeply, the opening is elastically deformed to expand the inner diameter. Thereby, the inner peripheral surface of the 1st connection pipe 81 and the 2nd connection pipe 82 can be stuck to the whole outer peripheral surface of the part which inserted the medical instrument. Therefore, even if the connecting part of the medical device is somewhat irregular, it is possible to secure a wide contact surface between the connecting pipe 8 and the medical device, so that the cleaning water can prevent or prevent leakage to a minimum. , A reduction in cleaning power can be suppressed. In addition, the first connecting pipe 81 and the second connecting pipe 82 can be adjusted by adjusting the length of the silicon tube whose inner diameter does not change, and the intermediate connection portion 83 can be formed at a low cost by cutting polypropylene. It is.
Furthermore, since the first connection pipe 81 and the second connection pipe 82 can be easily removed from the intermediate connection portion 83, the connection pipe can be easily formed into a connection pipe having a shape corresponding to the medical instrument to be connected or a connection pipe branched into a plurality. Can be replaced. The material of the intermediate connecting portion 83 is not only polypropylene but also the first connecting tube so that it has heat resistance and corrosion resistance and can be easily connected to the first connecting tube 81 and the second connecting tube 82. If it is harder than 81 and the 2nd connecting pipe 82, it can be used.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment. In the present embodiment, as shown in FIG. 6, the same connection pipe 72 fitted in the water inlet pipe 71 a is used to connect the olives P in cascade, but the thickness varies depending on the type of the olives P. Different connecting pipes or connecting pipes that branch into two or three branches or more can be used.

  INDUSTRIAL APPLICABILITY The present invention is suitable for a medical device cleaning apparatus having a pipeline that requires cleaning. In particular, since as many medical devices as possible can be connected in cascade in the length direction of the cleaning tank and stored at a time, it is possible to perform cleaning at a time, which is optimal for a medical device having a short length such as an olief. In addition, the cleaning device of the present invention is operated by incising a suction fistula, a medical tube, an abdomen, etc. used when sucking out body fluids such as saliva and nasal discharge, medicinal fluids, and cleaning fluids by placing them in the oral cavity or nostril It is also ideal for cleaning surgical instruments used in the process.
