The lower part of the collecting tank 8 is provided with a drain outlet which is provided with a sealing cover.

The specific implementation process is as follows: cleaning medical instruments in the cleaning box 6, draining water, putting the medical instruments into the disinfection box 2, and injecting disinfectant into the disinfection box 2 for disinfection. When a patient needs to be nursed, the frame body 1 is pushed to realize the movement of the disinfection box 2 and the cleaning box 6, so that the movement of medical instruments is realized; simultaneously, the switch is pressed, so that the heating pipe is started by the switch, the heating pipe heats the heating space, the water pump is turned on to add water into the heating cavity, and the water is heated by the heating pipe.

In the moving process of the frame body 1, the sliding wheel 12 continuously rotates to drive the rotating shaft 13 to rotate, so that the cam 14 rotates, the piston rod 52 drives the piston 51 to move up and down in a reciprocating mode when the cam 14 rotates, intermittent water pumping and draining of the water guide barrel 5 are achieved, water is drained into the cleaning box 6, the cleaning box 6 is washed and cleaned, and the water is drained into the collecting tank 8 through the water drainage pipe 62.

With the continuous heating of the heating pipe, the temperature of the water in the heating cavity is gradually increased, the temperature of the trifluoroacetic acid solution is gradually increased, and the boiling point of the trifluoroacetic acid solution is lower, so that the trifluoroacetic acid solution is gasified and expanded. After the trifluoroacetic acid solution is gasified and expanded, the pressure intensity of the liquid storage cavity is increased to push the push plate 7 to slide, so that the movable rod 71 drives the rack 72 to move, and the gear ring 64 drives the rotary valve 63 to rotate and close. And the cleaning tank begins to store water. And the trifluoroacetic acid solution pushes the sliding block 411 to move upwards after expanding, and the sliding block 411 can rotate when moving upwards because the thread pair formed by the sliding block 411 and the sliding hole does not meet the self-locking condition, thereby realizing the rotation and the upwards movement of the supporting plate 3. When the supporting plate 3 rotates, the limiting protrusion 32 is used for limiting, and the occurrence of the damage caused by relative impact of medical instruments can be avoided. And the supporting plate 3 moves upwards and is separated from the disinfectant in the rotating process, and the disinfectant on the medical instrument is thrown off under the action of the rotating centrifugal force, so that the medical instrument is convenient to use.

When the frame body 1 moves to the position to be used, the heating pipe continues to heat, and the gasified trifluoroacetic acid solution is kept warm, so that the support of the support plate 3 is realized. The cover body 9 on the sterilizing box 2 is opened again, and the medical instrument is taken out for use. After the medical instrument is used, the cover body 9 on the cleaning box 6 is opened, and the medical instrument is put into the cleaning box 6 for soaking and cleaning. After the nursing of the patient is completed, the frame body 1 is pushed to leave the sickbed, and the switch is pressed, so that the heating pipe is closed. And stopping heating the water in the heating cavity. And in the process of pushing the frame body 1, the water guide barrel 5 can continuously fill water into the cleaning box 6 to clean the medical apparatus. Since the water in the water guide barrel 5 is discharged under the action of the increased pressure when the piston 51 moves downwards, the water has a certain initial speed when being discharged into the cleaning tank 6, and the water impacts on the medical instrument, so that the cleaning effect is better.

When moving support body 1 to the parking position, open the water pump, to heating intracavity makeup water, the temperature in heating chamber reduces gradually this moment for the temperature of trifluoroacetic acid solution reduces gradually and liquefies, thereby makes the pressure of liquid reserve tank reduce, and the power of extrusion push pedal 7 disappears, therefore rack 72 resets under the effect of piece that resets, drives rack 72 antiport, thereby rotary valve 63 reverses and opens, will wash in the case 6 sewage discharge after the medical instrument in the collecting box.

After the medical instrument washs the completion, take out and put into on the backup pad 3 in disinfect box 2 to extrude backup pad 3 downwards, make backup pad 3 move down and reset, realize that medical instrument and antiseptic solution contact disinfect, be convenient for use next time.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications should not be construed as affecting the performance of the invention and its practical application.
