DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiment. In FIG. 1 and FIG. 2, the affected-part cleaning apparatus includes a cleaning apparatus main body 1, and a cleaning liquid is supplied to the affected part to clean the body. And a drainage collection unit 3 that collects drainage from which the affected part has been cleaned. The cleaning liquid supply means 2 includes a cleaning liquid container 4 for storing the cleaning liquid, a supply nozzle 5 for supplying the cleaning liquid to the affected area, and a supply tube 6 made of a soft synthetic resin or the like connecting the supply nozzle 5 and the cleaning liquid container 4. ing. In the middle of the supply tube 6, there is provided a supply pump 7 which obtains a pumping action while crushing the supply tube 6 by a rotating roller, and is discharged from the supply pump 7 downstream of the supply pump 7. A heater 8 for heating the cleaning liquid to a required temperature is provided. In the present embodiment, as shown by a broken line in FIG. 1, the supply tube 6 is arranged in a meandering manner at a portion heated by the heater 8, and the meandering portion is larger in diameter than other portions. It is formed in a bag shape.

A control device 9 for controlling the operation of the supply pump 7 is provided inside the cleaning device main body 1, and a control panel 9 provided in the cleaning device main body 1 controls the control device 9 to supply the cleaning liquid per unit time. , The operation of the supply pump 7 can be controlled by the control device 9 so as to obtain the discharge flow rate per unit time. The operation start and stop of the supply pump 7 are basically performed in accordance with a signal input from the operation panel 10 to the control device 9.
The total flow rate of the cleaning liquid from the start of the operation of the supply pump 7 can be displayed by the display means provided at 0. Further, a liquid shortage detector 11 is provided at a position close to the supply tube 6 which is on the upstream side of the supply pump 7.
When the liquid-out detector 11 detects that the supply tube 6 is empty and the cleaning liquid in the cleaning liquid container 4 has been consumed and emptied, this is input to the controller 9. I am trying to do it. At this time, the operation of the cleaning liquid supply means 2 is stopped by the control device 9.

Next, the drainage collecting means 3 is provided with a first suction nozzle 14A for collecting drainage that has washed the affected part of the patient.
And a second suction nozzle 14B, and each of the nozzles 14A, 14B is connected to the distal end of the collection tube 15A, 15B. The ends of the collection tubes 15A and 15B are connected to a first drainage container 16A and a second drainage container 16B.
And the collected drainage is stored in both of the drainage containers 16A and 16B. The two drainage containers 16A and 16B are connected via a connection tube 17 to a vacuum pump 18 serving as a negative pressure source or a connector 19 connectable to a supply port of an existing negative pressure source installed in the building. A negative pressure can be introduced into the two drainage containers 16A and 16B from the negative pressure sources via the connection tube 17. When a negative pressure is introduced, the drained liquid after washing is sucked through the nozzles 14A and 14B and the collection tubes 15A and 15B, and the drainage containers 16A and 16A are discharged.

When the A and 16B are damaged, the first filter 22 is for collecting the waste liquid stored in them, and the first filter 22 filters minute dust and the like when a negative pressure is introduced into both the waste containers 16A and 16B. It is for doing.

In the non-operating state, the three-way flow path switching valve 23 is connected to the vacuum pump 18 or the negative pressure source of the existing equipment connected via the connector 19 and the two drainage containers 16A, 16A,
6B while preventing the second filter 25 from communicating with these negative pressure sources,
The atmosphere can be introduced from the second filter 25 to the negative pressure source. At this time, minute dust in the air introduced into the negative pressure source is filtered by the second filter 25. The connection tube 17 that connects the second filter 25 and the three-way flow switching valve 23 is provided with a variable orifice 26, thereby adjusting the amount of air introduced from the second filter 25 to the negative pressure source. can do. When the three-way flow switching valve 23 is operated with respect to the non-operating state, the communication between the second filter 25 and the negative pressure source is blocked to prevent the introduction of the atmosphere and the negative pressure source. And the two drainage containers 16A and 16B communicate with each other. In the present embodiment, the three-way flow path switching valve 23 is operated when the cleaning liquid supply unit 2 supplies the cleaning liquid to the affected part. When the connector 19 is connected to an existing negative pressure source in the building and a negative pressure is introduced into both the drainage containers 16A and 16B by only the negative pressure source on the connector 19 side, the three-way flow path switching is performed. The stop state and the operation state of the valve 23 are appropriately repeated, and the amount of air introduced by the variable orifice 26 is adjusted to adjust the magnitude of the negative pressure of the negative pressure source. With this configuration, when obtaining a negative pressure from the existing negative pressure source in the building, a negative pressure of a required magnitude can be introduced into both of the drainage containers 16A and 16B.

In this embodiment, a vacuum pump 18 as a negative pressure source and a negative pressure source as existing equipment of a building connected by a connector 19 are switched as necessary, and either of the negative pressure sources A negative pressure is introduced into the drainage containers 16A and 16B. When the vacuum pump 18 is used as the negative pressure source, when the magnitude of the negative pressure of the vacuum pump 18 greatly deviates from the set value, the three-way flow path switching valve 23 is set to the operating state as described above. By repeating the stop state, the magnitude of the negative pressure of the vacuum pump 18 is maintained at the set value. The buffer tank 24 provided on the downstream side of the three-way flow switching valve 23 temporarily stores air to buffer pressure fluctuations. Is provided with a pressure sensor 29 for detecting the negative pressure. The connection tube 17 on the downstream side of the pressure sensor 29 is branched into two, and one end of the connection tube 17 is connected to the vacuum pump 18.
And the other end of the connector 1
9 is connected. A manual three-way switching valve 30 is provided at a location where the connection tube 17 is branched.
A and 16B are connected to the vacuum pump 18, while the drainage containers 16A and 16B are connected to the supply port of the existing negative pressure source laid in the building via the connector 19.

Reference numeral 1 is open when the cleaning liquid is supplied to the affected part, and the supply of the cleaning liquid to the supply nozzle 5 is permitted. Further, the control device 9 of the present embodiment is configured so that the supply pump 7
If there is an operation stop command to the supply pump 7 after the operation start command to the
Is stopped, and immediately thereafter, the supply pump 7 is automatically reversed by a predetermined amount. As described above, the control device 9 reverses the supply pump 7 by a predetermined amount, so that the cleaning liquid remaining in the supply nozzle 5 flows backward to the upstream side of the supply nozzle 5, and when the state is reached, The supply nozzle 5 is gripped and closed by the clamp 31. As a result, it is possible to reliably prevent the cleaning liquid from remaining in the supply nozzle 5, and it is possible to appropriately prevent the liquid from flowing from the supply nozzle 5 to the affected part after the operation of the supply pump 7 is stopped. As in the present embodiment, when the supply tube 6 serving as the location of the heater 8 is expanded and arranged in a meandering manner, the meandering portion which has been expanded by the cleaning liquid during the operation of the supply pump 7 is supplied. Since the diameter is reduced when the operation of the pump 7 is stopped, there is a possibility that the liquid dripping from the supply nozzle 5 may increase accordingly. However, in the present embodiment, the supply nozzle is configured as described above. 5 can be reliably prevented from dripping to the affected area.
