[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides the following technical solution: a medical dressing changing device that is easy to adjust.

[0025] Example 1: By setting the motor 2 and the limit column 3, the working plate 4 and the vertical plate 6 can be moved in the vertical direction, and then the height of the placement plate 5 can be adjusted, so that medical staff can change the patient's dressing more flexibly according to the actual situation, such as Figures 1-4 As shown, it includes a dressing change bed 1, the lower surface of the dressing change bed 1 is bolted to a bracket, and the surface of the front bracket is bolted to a motor 2, and the lower surface of the dressing change bed 1 is fixedly connected to a limiting column 3; the surface of the limiting column 3 is sleeved and connected to a working plate 4, and the upper surface of the working plate 4 is fixedly connected to a vertical plate 6, and the end of the vertical plate 6 is fixedly connected to a placement plate 5; a long pin 11 is provided for sliding inside the vertical plate 6; the output end of the motor 2 is fixedly connected to a threaded rod 32, and the surface of the threaded rod 32 is threadedly connected to the working plate 4, and the left view of the vertical plate 6 is an inverted "U" shape.

[0026] When in use, the patient places his legs on the placement plate 5, and then starts the motor 2. The motor 2 drives the threaded rod 32 to work synchronously. At this time, the working plate 4 rises under the action of the threaded rod 32 and the limiting column 3, and then the vertical plate 6 and the placement plate 5 are shown. At this time, the patient's buttocks are lifted, which is convenient for the staff to change the dressing. The work process is quick and convenient, and the work efficiency is high.

[0027] Embodiment 2: The difference from embodiment 1 is that, by setting the lifting structure, the extrusion plate 20 can make reciprocating linear motion in the vertical direction, and then the airbag 12 is intermittently squeezed, so that the nozzle 19 can intermittently spray the disinfectant, which improves safety. Figure 5-Figure 7 As shown, the lower surface of the placement plate 5 is connected to the extrusion plate 20 through a lifting structure, and the upper surface of the placement plate 5 is bonded with an airbag 12; the lifting structure includes a lower connecting rod 21 slidably arranged inside the placement plate 5, and the upper surface of the lower connecting rod 21 is fixedly connected to the lower surface of the extrusion plate 20, and the lower surface of the dressing change bed 1 is fixedly connected to the lower connecting plate 7, and the lower connecting plates 7 are symmetrically distributed on both sides of the dressing change bed 1.

[0028] The surface of the lower connecting plate 7 is fixedly connected to the first magnet 8, the left side of the long pin 11 is fixedly connected to the movable plate 9, and the surface of the movable plate 9 is fixedly connected to the second magnet 10, and the long pins 11 are symmetrically distributed on the upper and lower sides of the movable plate 9.

[0029] The magnetic poles on the surface of the second magnet 10 are the same as the magnetic poles on the surface of the first magnet 8, and the second magnets 10 are distributed at equal intervals on the surface of the movable plate 9. The left and right sides of the lower connecting rod 21 are fixedly connected to the cross bar 22, and the surface of the cross bar 22 is fixedly connected to the force block 23, and the surface of the force block 23 is inclined, and the surface of the force block 23 is in contact with the end of the long pin 11.

[0030] The lower surface of the placement plate 5 is fixedly connected to a limiting rod 24, and the limiting rod 24 passes through the inside of the cross bar 22, and the end of the limiting rod 24 is fixedly connected to a baffle 26, and a connecting spring 25 is fixedly connected between the baffle 26 and the cross bar 22. The upper surface of the airbag 12 is fixedly connected to the feed pipe 13, and the lower surface of the airbag 12 is fixedly connected to the discharge pipe 14, and the surface of the feed pipe 13 and the surface of the working tube 18 are both fixedly connected to a one-way valve.

[0031] When the vertical plate 6 rises, the movable plate 9 rises synchronously. At this time, the second magnet 10 on the surface of the movable plate 9 will intermittently approach the first magnet 8 on the surface of the lower connecting plate 7. When the second magnet 10 approaches the first magnet 8, the repulsive magnetic force received by the movable plate 9 increases. At this time, the movable plate 9 drives the long pin 11 to move in the direction of pushing the force block 23. At this time, the force block 23 and the cross bar 22 descend (the limit rod 24 makes the cross bar 22 move only in the vertical direction). At the same time, the connecting spring 25 is squeezed. When the second magnet 10 is away from the first magnet 8, the repulsive magnetic force received by the movable plate 9 decreases. At this time, the cross bar 22 and the force block 23 rise under the action of the connecting spring 25, and then the force block 23 will push the long pin 11 to move back, and repeat the above process. The movable plate 9 and the long pin 11 make reciprocating linear motion in the horizontal direction, while the cross bar 22 and the lower connecting rod 21 and the extrusion plate 20 make reciprocating linear motion in the vertical direction. When the lower connecting rod 21 descends, the extrusion plate 20 will squeeze the airbag 12. At this time, the airbag 12 provides disinfectant to the nozzle 19 through the discharge pipe 14 and the working pipe 18. The nozzle 19 sprays the disinfectant to disinfect the surrounding air, making subsequent dressing operations safer.

[0032] When the extrusion plate 20 rises and the airbag 12 is not squeezed, the airbag 12 will inhale air through the feed pipe 13. At this time, the airbag 12 expands, which is convenient for the next use of the airbag 12. During use, the one-way valve makes the flow direction of the disinfectant from the airbag 12 to the nozzle 19, and backflow will not occur, thereby ensuring stability. After long-term use, when there is less material inside the airbag 12, the airbag 12 can be fed through the feed pipe 13.

[0033] Embodiment 3: The difference from embodiment 2 is that the swing structure can make the nozzle 19 in a swinging state when working. At this time, the working range of the nozzle 19 is increased and the disinfection effect is better. Figures 8-10As shown, the lower surface of the placement plate 5 is connected to the connecting shaft 16 through a swinging structure, and the surface of the connecting shaft 16 is fixedly connected to the equipment plate 17, and the lower surface of the equipment plate 17 is fixedly connected to the nozzle 19, and the upper surface of the upper end long pin 11 is fixedly connected to the gear block 27 at equal intervals. The swinging structure includes a connecting plate 15 fixedly connected to the lower surface of the placement plate 5, and the connecting plate 15 is internally rotatably provided with a connecting shaft 16, and the end of the connecting shaft 16 is fixedly connected to a gear 28, and the gear 28 is meshed with the gear block 27. The upper surface of the equipment plate 17 is fixedly connected to the working pipe 18, and the working pipe 18 and the discharge pipe 14 are connected by an external hose.

[0034] When the long pin 11 makes reciprocating linear motion in the horizontal direction, the long pin 11 will drive the tooth block 27 to move synchronously. At this time, the tooth block 27 and the gear 28 are engaged, which will drive the connecting shaft 16 to rotate inside the connecting plate 15. The long pin 11 makes reciprocating linear motion, so the connecting shaft 16 rotates reciprocatingly. At this time, the nozzle 19 is in a reciprocating rotation state, and the working range of the nozzle 19 is expanded, which can better disinfect.

[0035] Embodiment 4: The difference from embodiment 3 is that the sound piece 31 is provided to remind the patient to leave the dressing room and protect the patient's privacy. Figure 2 and Figure 9 As shown, the surface of the long pin 11 is fixedly connected to the limit block 29, and the other side surface of the long pin 11 is fixedly connected to the knocking rod 30, and the end of the knocking rod 30 is convex, and the surface of the vertical plate 6 is fixedly connected to the sound piece 31.

[0036] During the movement of the long pin 11, the limit block 29 on the surface of the long pin 11 limits the maximum distance that the long pin 11 moves back, and the long pin 11 will not move excessively. At the same time, when the long pin 11 is working, it drives the knocking rod 30 to hit the clicker 31, causing the clicker 31 to make intermittent sounds, thereby reminding surrounding personnel to leave the dressing change position, protecting the patient's privacy, and at the same time allowing staff to concentrate their attention and ensure the effect of dressing change.

[0037] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
