[0030] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] As attached Figure 1 To the attached Figure 7 As shown:

[0032] Embodiment 1: The present invention provides a disinfection device for preventing arm infection, comprising a disinfection frame 1, a rotatably connected mounting plate 2 provided inside the disinfection frame 1, a placement hole 3 for inserting an arm provided inside the mounting plate 2, disinfection nozzles 4 evenly distributed on the inner wall of the mounting plate 2, a disinfection liquid delivery pipe 5 connected to the disinfection nozzle 4, and the other end of the disinfection liquid delivery pipe 5 connected to a disinfection liquid tank 6;

[0033] The outer wall of the disinfection frame 1 is provided with a nozzle adjustment assembly, which drives the disinfection nozzle 4 on the mounting plate 2 to change to different positions within the disinfection frame 1;

[0034] A collecting assembly is provided at the bottom of the disinfection frame 1, and the collecting assembly is used to collect the disinfectant.

[0035] It should be noted that, by arranging a mounting plate 2 inside the disinfection frame 1, a plurality of disinfection nozzles 4 are distributed on the inner wall of the mounting plate 2. When the injured arm is placed in the placement hole 3, the disinfectant is sprayed out through the disinfection nozzle 4 through the disinfectant delivery pipe 5. The nozzle adjustment assembly provided can drive the disinfectant nozzle to realize rotary spraying, thereby performing all-round disinfection of the injured arm, improving the uniformity of disinfection, and avoiding incomplete disinfection.

[0036] In this embodiment, the disinfection frame 1 is designed as a rectangular body with a hollow interior. A limiting concave ring 7 is symmetrically provided inside the disinfection frame 1, and an annular clamping groove 8 is provided on the limiting concave ring 7. A clamping ring 9 is symmetrically provided on the outer wall of the mounting plate 2, and the clamping ring 9 is movably engaged in the clamping groove 8.

[0037] It should be noted that the limiting concave ring 7 is fixedly connected to the disinfection frame 1. By setting a groove 8 in the limiting concave ring 7, the snap ring 9 is fixedly connected to the mounting plate 2. The snap ring 9 and the groove 8 cooperate with each other, so that the mounting plate 2 can be rotated inside the disinfection frame 1, indirectly driving the disinfection nozzle 4 to adjust its position.

[0038] In this embodiment, sealing air cushions 10 covering the inlet and outlet are provided at both ends of the disinfection frame 1, and a through hole 11 is provided in the middle position of the sealing air cushion 10. Connecting plates 12 are symmetrically provided at the bottom of the disinfection frame 1, and a supporting plate 13 is provided at the bottom of the connecting plate 12. The disinfectant box 6 is placed on the supporting plate 13.

[0039] It should be noted that a through hole 11 is designed on the sealing air cushion 10, so that the patient's arm can be inserted into the placement hole 3 through the through hole 11. The interior of the sealing air cushion 10 is filled with gas so that the through hole 11 can fit the arm. At the same time, the sealing air cushion 10 covers the inlet and outlet of the disinfection frame 1, thereby ensuring that the disinfectant will not flow out of the disinfection frame 1 during the disinfection nozzle 4 disinfecting the patient, thereby improving the level of hygiene and safety.

[0040] In this embodiment, a placement rack 14 is provided in front of the disinfection frame 1, the bottom of the placement rack 14 is connected to the supporting plate 13, and the top of the placement rack 14 is provided with a downward placement groove 15, the vertical section of the placement groove 15 is "V"-shaped, and a foam pad 16 is provided in the placement groove 15.

[0041] It should be noted that by arranging a placement rack 14 in front of the disinfection frame 1 and a placement slot 15 on the top of the placement rack 14, the patient's arm can be placed on the placement slot 15 after being inserted into the placement hole 3, thereby providing support for the arm and avoiding arm soreness caused by long disinfection time. At the same time, a foam pad 16 is arranged in the placement slot 15. The foam pad 16 has a certain elasticity, which improves the comfort of the patient after placing his arm on it.

[0042] In this embodiment, the nozzle adjustment assembly includes a driven gear ring 17, a driving gear 18 and a linkage rod 19. The linkage rod 19 is laterally arranged on the side of the disinfection frame 1. The driving gear 18 is symmetrically fixedly connected to the linkage rod 19. A positioning plate 20 is provided between the linkage rod 19 and the disinfection frame 1.

[0043] It should be noted that the linkage rod 19 is rotatably connected to the positioning plate 20. When the linkage rod 19 rotates, it drives the fixedly connected driving gear 18 to rotate, thereby cooperating with the driven gear ring 17 to rotate.

[0044] In this embodiment, gear holes 21 are symmetrically provided on the side panels of the disinfection frame 1, and the gear teeth on the driving gear 18 pass through the gear hole 21. A gear box 22 covering the driving gear 18 is provided outside the gear hole 21. The gear ring is fixedly mounted on the outer wall of the mounting plate 2, and the gear teeth on the outer wall of the gear ring cooperate with the driving gear 18. A rotating handle 34 is provided at one end of the linkage rod 19.

[0045] It should be noted that the rotating handle 34 is fixedly connected to the linkage rod 19, thereby controlling the rotation angle of the linkage rod 19. When the linkage rod 19 rotates, the driving gear 18 is driven to cooperate with the driven gear ring 17. The driven gear ring 17 is fixedly connected to the mounting plate 2, so that the mounting plate 2 is rotated inside the disinfection frame 1. By rotating the disinfection frame 1, the disinfection nozzle 4 on the inner wall is driven to perform rotational spraying, thereby achieving all-round disinfection of the arm. For the arm with a more serious injury, comprehensive disinfection is guaranteed, the efficiency of disinfection is improved, and the occurrence of infection in the later stage is reduced.

[0046] A covered gear box 22 is provided on the gear hole 21, which can hide the driving gear 18 therein, so as to prevent it from being touched by medical staff during rotation, and also to hide it therein, thereby improving the aesthetics;

[0047] In this embodiment, the rotating handle 34 is connected to the linkage rod 19, and the rotation and disinfection of the disinfection nozzle 4 are controlled by people themselves, but it is not limited to manual control. The linkage rod 19 can also be connected to a motor of an external power supply to achieve automatic rotation of the linkage rod 19.

[0048] In this embodiment, a sealing plate 23 is provided in the placement hole 3, and the sealing plate 23 blocks the water outlet of the disinfection nozzle 4. A notch 24 is also provided on the sealing plate 23. A matching ring 25 is provided on the side of the sealing plate 23 away from the placement rack 14. A second card groove 26 is provided on the side of the matching ring 25 close to the sealing plate 23. A rubber strip 27 is provided on the relative ring wall inside the second card groove 26. The second card groove 26 cooperates with the mounting plate 2 to realize the closure of the disinfection nozzle 4 by the sealing plate 23.

[0049] It should be noted that the matching ring 25 is fixedly connected to the sealing plate 23. The sealing plate 23 can be inserted into the mounting plate 2 through the second card slot 26 and the rubber strip 27. The outer wall of the sealing plate 23 fits with the liquid outlet 28 of the disinfection nozzle 4, thereby blocking the spray port of the disinfection nozzle 4 and preventing the disinfectant from spraying out from the disinfection nozzle 4. However, there is also a notch 24 on the sealing plate 23. When the position of the matching ring 25 is adjusted so that the disinfection nozzle 4 is located on the notch 24, the disinfectant will be sprayed out, and the other disinfection nozzles 4 will remain in a closed state. By adjusting the position of the notch 24, when a specific position of the patient's arm needs to be disinfected, the disinfection nozzle 4 can be sprayed at a fixed point, and the other disinfection nozzles 4 will not spray disinfection, thereby improving the flexibility of disinfection, and can be flexibly adjusted according to the position of the patient's arm that needs to be disinfected.

[0050] In this embodiment, a liquid outlet 28 is provided on the bottom plate of the disinfection frame 1, and the collection assembly includes a collection box 29, a baffle 30, a slide rail 31 and a slider 32. The baffle 30 is installed between the two connecting plates 12 near the side of the entrance of the placement hole 3. The collection box 29 has a liquid inlet 33, the slider 32 is symmetrically installed at the bottom of the collection box 29, the slide rail 31 is symmetrically installed on the top of the supporting plate 13, and the slider 32 and the slide rail 31 cooperate with each other. When the collection box 29 is pushed to fit with the baffle 30, the liquid inlet 33 on the collection box 29 coincides with the liquid outlet 28 on the disinfection frame 1.

[0051] It should be noted that a liquid outlet 28 is provided on the disinfection frame 1 so that the disinfectant after disinfection is completed will flow out from the liquid outlet 28, and a baffle 30 is provided between the two connecting plates 12, so that when the collection box 29 is pushed to the bottom of the disinfection frame 1, the collection box 29 touches the baffle 30, so that the liquid outlet 28 and the liquid inlet 33 coincide with each other, so that the disinfectant after disinfection is completed can enter the collection box 29 and be collected centrally;

[0052] Moreover, with the cooperation of the slider 32 and the slide rail 31, the collection box 29 can be pulled out from the bottom of the disinfection frame 1 after the disinfectant is collected, thereby improving convenience.

[0053] As can be seen from the above, when the injured arm needs to be disinfected, the arm is passed through the through hole 11 on the sealing air cushion 10 into the inside of the placement hole 3, and the arm is placed in a suitable position in the placement slot 15 on the placement rack 14. After the arm is placed, there is a pump body in the disinfectant tank 6. The pump body is started to pump the disinfectant stored in the disinfectant tank 6 into the disinfectant delivery pipe 5, and then enters the disinfectant nozzle 4 through the disinfectant delivery pipe 5 and is sprayed out and sprayed in the placement hole 3, thereby achieving disinfection of the arm.

[0054] At the same time, evenly distributed disinfection nozzles 4 are provided in the mounting plate 2. Medical staff can rotate the rotating handle 34 to drive the linkage rod 19 to rotate. A fixedly connected driving gear 18 is provided on the linkage rod 19. The driving gear 18 cooperates with the driven gear ring 17 connected to the outer wall of the mounting plate 2, thereby driving the mounting plate 2 to move in the limiting concave ring 7 to adjust the position of the disinfection nozzle 4. When the entire arm of the patient needs to be disinfected, all-round disinfection of the patient can be achieved by rotation, thereby improving the degree of disinfection.

[0055] When the patient's arm only needs to be disinfected at a specific position, before placing the arm into the placement hole 3, the blocking plate 23 is first inserted into the placement hole 3, so that the second slot 26 on the matching ring 25 is inserted into the mounting plate 2. After the insertion is completed, the outer wall of the blocking plate 23 blocks the disinfection nozzle 4, and the disinfectant will no longer be sprayed out. However, a notch 24 is also provided on the blocking plate 23. By aligning the notch 24 with the injured disinfection position of the patient, during the disinfection process, other disinfection nozzles 4 will not spray disinfectant, and only the disinfection nozzle 4 on the notch 24 will spray out, thereby achieving fixed-point disinfection of the patient's arm and improving flexibility.

[0056] After the disinfection is completed, a liquid outlet 28 is set on the disinfection frame 1, and the collection box 29 has been pushed to the bottom of the disinfection frame 1 before the patient's arm is disinfected, so that the liquid outlet 28 and the liquid inlet 33 overlap with each other. During the disinfection process, the sprayed disinfectant will eventually flow into the collection box 29 through the liquid outlet 28, thereby realizing the collection of waste disinfectant and avoiding pollution.

[0057] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
