By providing the elastic rope 16, it can meet the needs of patients with different fat and thin degrees, because the wound height of a thin patient may be lower than that of a fat patient. By providing the elastic rope 16, wounds in different positions can be met.

[0035] The collecting mechanism also includes a cylinder 2 32 fixedly mounted on the processing box 27, the protruding end of the cylinder 2 32 is fixedly connected to the round rod 31, one end of the round rod 31 is rotatably connected to one end of the telescopic rod 30, the other end of the telescopic rod 30 is slidably matched with the inclined groove 28 and the straight groove 29 on the processing box 27, the inclined groove 28 is connected to the straight groove 29, the other end of the round rod 31 is rotatably connected to one end of the lifting rod 1 33, the other end of the lifting rod 1 33 is rotatably connected to one end of the driving rod 34, the other end of the driving rod 34 is rotatably connected to one end of the L-shaped rod 51, the other end of the L-shaped rod 51 is fixedly connected to the lower extrusion rod 38, the lower extrusion rod 38 is slidably matched with the collecting box 39, and the end of the telescopic rod 30 away from the round rod 31 is rotatably matched with the upper extrusion rod 47.

[0036] Specifically, the upper squeezing rod 47 can slide on the inclined groove 28 and the straight groove 29. The upper squeezing rod 47 and the lower squeezing rod 38 are used to squeeze the used and discarded sterile cotton to remove blood in the sterile cotton.

[0037] As a preferred solution, a door that can be opened and closed can be provided at the connection between the bracket 9 and the processing box 27. When the upper squeezing rod 47 and the lower squeezing rod 38 complete the squeezing of the disinfectant cotton and the application of medicine to the wound, the door can be opened to take out the pressurized disinfectant cotton and place it in the lower squeezing rod 38.

[0038] As another preferred scheme, a conical hole can be set under the processing box 27, and the diameter of the conical hole close to the upper extrusion rod 47 is smaller than the diameter of the end away from the upper extrusion rod 47. At the same time, a hair dryer is set inside the processing box 27. After the extrusion of the sterilizing cotton is completed, the hair dryer can be started to blow the extruded sterilizing cotton on the lower extrusion rod 38 into the conical hole. The conical hole is connected to the collection box 39, so that the sterilizing cotton will automatically fall into the collection box 39.

[0039] The collecting mechanism also includes a pressing block 35, one end of which is rotatably connected to a lifting rod 33, and the other end of the pressing block 35 is connected to one end of a water pipe 36, the other end of the water pipe 36 is connected to a plurality of nozzles 37, and the water pipe 36 is connected to a water tank 52 fixedly mounted on a collecting box 39, and the nozzle 37 is located on one side of a lower extrusion rod 38.

[0040] Specifically, a water pump is provided in the water tank 52, and the water pump can transport the water in the water tank 52 to the water pipe 36. Water is sprayed from the nozzle 37 to wash the blood water inside the treatment box 27.

[0041] The collecting mechanism also includes a rotating rod 40, one end of which is rotatably connected to the pressing block 35, the other end of which is rotatably connected to the rotating rod 40, and the rotating rod 40 is rotatably installed on the collecting box 39. The other end of the rotating rod 40 is connected to one end of a rotating rod 42, the other end of the rotating rod 42 is connected to one end of a lifting rod 43, the other end of the lifting rod 43 is connected to a dredging rod 44, the lifting rod 43 is slidably matched with a storage box 53, and the storage box 53 is connected to a processing box 27, a through hole 46 is provided inside the processing box 27, and the through hole 46 is located above the dredging rod 44.

[0042] Specifically, the dredging rod 44 is fixedly installed below the processing box 27, and the dredging rod 44 is connected to the collecting box 2 45, and the collecting box 2 45 is fixedly installed below the dredging rod 44. Fig.10 As shown, the part inside the processing box 27 where the through hole 46 is provided is in an inclined state, which facilitates the flow of waste water and blood in the disinfection cotton.

[0043] A contact switch 2 50 and a contact switch 1 48 are provided inside the processing box 27 . The contact switch 2 50 is fixedly installed inside the processing box 27 . The contact switch 1 48 is located below the contact switch 2 50 . The contact switch 1 48 is fixedly installed on a mounting plate 49 , and the mounting plate 49 is connected to the round rod 31 .

[0044] Working principle: When changing the dressing of the patient's wound, let the patient lie on the bed 1, and then push the bracket 9 and the turntable 4 according to the position of the wound. The turntable 4 moves on the horizontal guide rod 2 through the moving block. The bracket 9 is fixed to the processing box 27, and the processing box 27 and the collection box 39 are fixed, so the processing box 27 can be moved on the moving block by pushing the bracket 9. By moving the bracket 9 and the turntable 4, on the one hand, it is convenient for the patient to lie on the bed 1, and on the other hand, it can meet the needs of applying medicine to wounds in different positions.

[0045] When applying medicine to a patient lying on the bed 1, different drawers 5 can be pulled out from the turntable 4 by rotating the turntable 4. Since the ball head rod 3 does not rotate relative to the turntable 4, when the turntable 4 is rotated, the sliding block 7 will gradually rotate to contact the ball head rod 3. In this way, when the inclined surface 8 rotates along the ball head rod 3, the ball head rod 3 will push the sliding block 7 away from the turntable 4. In this way, the sliding block 7 drives the pulling rod 6 and the drawer 5 to be pulled out from the turntable 4, so that the required medicines stored in the drawer 5 can be taken out, which is convenient for medical staff to use.

[0046] As an optional, in order to facilitate the rotation of the turntable 4, a handle can be installed on the turntable 4 for the medical staff to operate. In addition, different medicines are installed in the multiple drawers 5, which can facilitate the medical staff to select according to actual conditions.

[0047] In addition, during the process of applying medicine, medical staff can hold the handle 17 and bring the clip 10 with disinfectant cotton close to the patient's wound to wipe the blood on the wound and disinfect it. The elastic rope 16 is an elastic rope and is wound inside the winding box 18. When the handle 17 is pulled, the elastic rope 16 can be released to meet the needs of different distances (the distance between the wound and the connecting plate 11 is also different due to the different fatness and thinness of the patients).

[0048] In addition, by starting the motor 22, the motor 22 can drive the threaded rod 21 to rotate, so that the sliding plate 19 drives the winding box 18 and the clip 10 to move in the horizontal direction, thereby meeting the use requirements.

[0049] After the disinfection is completed, the sliding plate 19 drives the winding box 18 and the connecting plate 11 to move to the side close to the bracket 9, and the connecting rod 20 drives the feed trough 23 to slide together on the bracket 9. The feed trough 23 has the same movement direction as the clip 10, and in the initial state, the clip 10 is located in front of the end of the feed trough 23. During the movement, the clip 10 contacts the wedge block 14 and slides along the wedge block 14. The second inclined surface 15 will gradually insert into the center of the clip 10, and then the clip 10 will be stretched open. In this process, the short rod 13 plays a guiding role, and the reset spring 12 will be compressed to generate elastic force. The function of the reset spring 12 is to assist the reset of the clip 10 and clamp the disinfection cotton. After the inclined plane 15 opens the two ends of the clip 10, the disinfectant cotton is no longer clamped by the clip 10, and the disinfectant cotton will fall into the processing box 27 and fall onto the lower extrusion rod 38 (the feeding trough 23 and the clip 10 move at the same time, and the clip 10 is located in front of the end of the feeding trough 23, so the fallen disinfectant cotton will not fall onto the feeding trough 23) to complete the collection. In this way, when the disinfectant cotton is recycled after use, the disinfectant cotton will not come into direct contact with medical staff, which can effectively avoid infection to medical staff.

[0050] When new sterilizing cotton is needed, the cylinder 1 25 is started, and the baffle 26 is pulled by the extended end of the cylinder 1 25 to make the baffle 26 leave the bottom of the storage box 24, so that the sterilizing cotton stored in the storage box 24 will fall onto the feeding trough 23 (one sterilizing cotton falls at a time), and then the extended end of the cylinder 1 25 is extended, and the sterilizing cotton is pushed to the side where the wedge block 14 is located through the baffle 26, and then the medical staff removes the clip 10 from the wedge block 14, and at the same time clamps the new sterilizing cotton on the feeding trough 23 and uses it (clamps the sterilizing cotton under the elastic force of the reset spring 12). In this way, the medical staff can avoid direct contact with the sterilizing cotton, causing contamination of the sterilizing cotton, and reducing the risk of infection of the patient.

[0051] Start the cylinder 2 32, so that the extended end of the cylinder 2 32 drives the round rod 31 to move downward, and the round rod 31 drives the telescopic rod 30 to move downward. The end of the telescopic rod 30 away from the round rod 31 will drive the upper extrusion rod 47 to move along the inclined groove 28, and then move downward along the straight groove 29. The straight groove 29 is smoothly connected with the inclined groove 28 (the purpose of setting the inclined groove 28 is to make the upper extrusion rod 47 not directly above the lower extrusion rod 38 in the initial state, so as not to interfere with the disinfection cotton falling directly onto the lower extrusion rod 38). During the downward movement of the round rod 31, the lifting rod 1 33 will also move downward, and the lifting rod 1 33 will push the pressing block 35 downward. At the same time, the driving rod 34 fixedly connected to the lifting rod 1 33 will rotate, and the other end of the driving rod 34 is connected to the L-shaped rod 51, so the L-shaped rod 51 will drive the lower extrusion rod 38 to move upward, so that the lower extrusion rod 38 and the upper extrusion rod 47 are close to each other, and then the lower extrusion rod 38 contacts the upper extrusion rod 47 to squeeze out the blood in the disinfection cotton falling on the lower extrusion rod 38. It should be noted that the extrusion occurs at the highest point of the through hole 46, that is, at the horizontal position below the treatment box 27, so that the blood water produced can only flow along the downward trend of the through hole 46, and will not splash when the blood water stays because the extrusion position is too high (such as Fig.10 As shown, the left side of the through hole 46 is in a horizontal state, that is, the position where the extrusion occurs).

[0052] After squeezing the sterilizing cotton, the door can be opened to take out the sterilizing cotton and put it into the collection box 39 for recycling and sterilization; or after the lower squeezing rod 38 moves downward, a blower can be used to blow the squeezed sterilizing cotton on the lower squeezing rod 38 into the conical hole, and the conical hole is connected to the collection box 39, so that the sterilizing cotton will automatically fall into the collection box 39. In addition, when the pressing block 35 moves downward, the rotating rod 1 40 will be pulled downward, and the rotating rod 1 40 drives the rotating rod 2 42 to move upward through the central rod 41. The rotating rod 2 42 moving upward drives the lifting rod 2 43 and the dredging rod 44 to move downward, and the dredging rod 44 will be inserted into the through hole 46. The function of the dredging rod 44 is to clean the through hole 46 to prevent blood from remaining. The generated blood will flow into the storage box 53 through the through hole 46, and the storage box 53 is connected to the collection box 2 45, and the blood will eventually flow into the collection box 2 45 to complete the collection.

[0053] At the same time, when the pressing block 35 moves downward, the water pipe 36 and the nozzle 37 will move downward. When the pressing block 35 moves upward, the water pipe 36 and the nozzle 37 will also move upward. Finally, the top of the nozzle 37 will move to a position higher than the through hole 46 in the processing box 27. At the same time, the upper side of the nozzle 37 bends to the side where the through hole 46 is located, and the water pump in the water tank 52 is started to spray water through the nozzle 37. The water flushes the through hole 46 to rinse the residual blood water and prevent the adverse consequences caused by the breeding of bacteria.

[0054] The mounting plate 49 also moves with the round rod 31, and the mounting plate 49 drives the contact switch 1 48 to move, so that the contact switch 1 48 and the contact switch 2 50 can be connected and disconnected, thereby generating different signals to control the start and stop of the round rod 31 and the water pump, etc. This belongs to the prior art and can be realized by those skilled in the art.
