Description

Technical Field

[0001] The invention relates to the technical field of medical disinfection equipment, in particular to a hand disinfection auxiliary device for medical staff in an infection department. Background Art

[0002] Hand disinfection of medical staff in infection departments is extremely important. Existing auxiliary induction disinfection equipment, such as induction hand sterilizers, use the induction principle to spray disinfectants in a contact-free manner to effectively avoid cross-infection. These devices are widely used in hospitals, food processing plants and other places. They are efficient, convenient and safe. Medical staff only need to put their hands into the induction area to automatically spray disinfectant to complete the disinfection process. There is no need to directly contact the disinfection equipment, which greatly reduces the risk of cross-infection.

[0003] The patent with application number CN202210220264.2 discloses a hand disinfection auxiliary device for medical staff in the infectious department, which includes a box body, a blocking part, an extrusion part, a cleaning part, a drying part, a driving part and a control box. The box body is a rectangular box-shaped structure, and two support plates are symmetrically installed on the bottom end surface of the box body, and a liquid storage barrel is installed in the box body. Four fixing seats are fixed to the box body by bolts. Because the extrusion plate is in contact with the water pipe, and when the extrusion plate elastically resets, the extrusion plate and the water pipe are in a collision state, the water droplets on the water pipe can be shaken off, thereby preventing the water droplets from remaining on the water pipe for a long time and increasing the probability of rust.

[0004] In current medical practice, medical staff need to use alcohol disinfectant, spray devices and air drying equipment in sequence to disinfect their hands. This process relies on high-precision sensors to ensure contactless operation. However, this multi-device system not only significantly increases the overall cost of the hand disinfection device, but also expands the floor space of the cleaning operation area, which can easily lead to queues and congestion for medical staff during peak hours. In addition, some medical staff stay in each disinfection link for longer than necessary, resulting in non-optimal use and waste of disinfection resources.

[0005] In view of this, we propose a hand disinfection auxiliary device for medical staff in infection departments. Summary of the invention

The first storage groove 112 and the second storage groove 113 are internally connected to pipes for replenishing alcohol disinfectant and cleaning water. The interior of the outer cover 120 is used to place the control mainboard to receive and process the data signal of the sensor 130. After the hot air blower 140 is started, it is used to blow the liquid on the hands of medical staff. The fixed bracket 150 is used to provide a fixed base point for the air pump 240.

[0034] In this embodiment, Figure 6-Figure 7 As shown, the driving device 200 includes an electric push rod 210, a mobile bracket 220 that moves with the telescopic rod of the electric push rod 210, a plurality of fixed pawls 230 regularly arranged on the inner side wall of one of the cross bars of the mobile bracket 220, two groups of symmetrically arranged air pumps 240 whose ends are fixed on the outer side wall of the mobile bracket 220, and a transmission mechanism 260 whose internal structure moves only when the mobile bracket 220 moves to the rear position; Specifically, the electric push rod 210 is fixedly connected to the inner wall of the outer cover body 120 by bolts, the ends of the telescopic rod of the electric push rod 210 are fixed to the outer walls of the left and right end horizontal plates of the mobile bracket 220, and a plurality of fixed pawls 230 are welded and fixed to the mobile bracket 220.

[0036] Furthermore, after the medical staff extends their hand under the sensor 130, the control main board built into the coat cover 120 receives the signal and controls the telescopic rod of the electric push rod 210 to start to retract. Subsequently, after the telescopic rod of the electric push rod 210 starts to retract, the movable bracket 220 moves backward along with its end, driving the pull rods in the two sets of air pumps 240 to move inward, and then injecting the external air into the first storage tank 112 and the second storage tank 113 through the two ventilation pipes 250 respectively.

[0037] In this embodiment, Figure 8As shown, the transmission mechanism 260 includes a dial 261, a center plate 262 disposed at the center of the top surface of the dial 261, a plurality of docking gears 263 regularly distributed on the outer ring wall of the center plate 262 for cooperating with the mobile bracket 220, a lever 264 rotating with the dial 261, and a groove wheel 265 cooperating with the lever 264 to rotate at a period of 90°; Specifically, the dial 261 is rotatably connected to the top surface of the fixed base plate 110, the center plate body 262 and the dial 261 are integrally formed, and a plurality of regularly distributed plate surface grooves 2620 are opened on the outer wall ring wall of the center plate body 262 and used to provide a rotation range for the docking gear 263.

[0038] Furthermore, the docking gear 263 is rotatably connected to the inside of the plate groove 2620 , and the tooth end of the docking gear 263 is bent toward the direction in which the fixed pawl 230 moves forward, and the lever 264 and the dial 261 are integrally formed.

[0039] Furthermore, as the movable bracket 220 moves backward, the fixed pawls 230 on the inner wall of the movable bracket 220 come into conflict with the docking gear 263, driving it to rotate one circle, thereby driving the dial 261 and the lever 264 to rotate one circle, thereby driving the groove wheel 265 to rotate 90°.

[0040] In this embodiment, Figure 9-10 As shown, the rotating device 300 includes a rotating disk 320 that moves synchronously with the groove wheel 265, and the rotating device 300 also includes a disinfectant extrusion head 330, a rectangular shower head 340 and an air guide grille 360 ​​that are regularly arranged on the bottom surface of the rotating disk 320; Specifically, the rotating disk 320 is rotatably connected to the inside of the rotating groove 111, and the rotating shaft 310 is fixedly connected to the center of the top surface of the rotating disk 320 by bolts. The top end of the rotating shaft 310 extends above the top surface of the fixed base plate 110 and is fixedly connected to the groove wheel 265 by a pin.

[0041] Furthermore, a plurality of disk through holes 321 connected to the disinfectant extrusion head 330 and the rectangular shower head 340 are respectively provided on the outer ring wall of the rotating disk 320.

[0042] Furthermore, the disinfectant extrusion head 330, the rectangular shower head 340 and the air guide grille 360 ​​are all clamped and fixed on the bottom surface of the rotating disk 320, and the top surface of the rotating disk 320 is clamped with an air guide duct 350 outside the circular hole above the air guide grille 360, and the top surface of the air guide duct 350 is in conflict with the top surface groove wall of the rotating groove 111.

[0043] Furthermore, when the groove wheel 265 rotates 90°, the rotating disk 320 is driven to rotate 90° through the rotating shaft 310, so that the disinfectant extrusion head 330 moves to above the medical staff's hand. Then, in the process of the electric push rod driving the movable bracket 220 to move forward, the alcohol disinfectant in the first storage tank 112 enters the disk through hole 321 through the connecting hole 114 under the influence of atmospheric pressure, and the disinfectant extrusion head 330 squeezes the alcohol disinfectant toward the medical staff's hand. After that, the movable bracket 220 continues to retract and extend twice with the electric push rod. When the rectangular shower 340 moves to above the medical staff's hand, the cleaning water in the second storage tank 113 is sprayed toward the medical staff's hand by the rectangular shower 340. When the air duct 350 moves to above the medical staff's hand, the hot air blower 140 is started. Subsequently, the rotating disk 320 is restored to its initial state after the movable bracket 220 is retracted again.
