[0023] In order to better understand the purpose, structure and function of the present invention, a medical device disinfection device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, a medical device disinfection device of the present invention comprises a disinfection cabinet, a first placement frame 4 for placing devices in the disinfection cabinet, a disinfection device for disinfecting the devices in the disinfection cabinet, and a discharge part for discharging disinfectant. When in use, it is only necessary to place the medical device to be disinfected on the first placement frame 4, and then start the disinfection device to disinfect the device, and the disinfectant sprayed by the disinfection device will be collected through the discharge part and discharged to the outside, which is convenient to use.

[0025] Specifically, the disinfection cabinet includes a cabinet body 1, a mounting opening 2 is opened on the cabinet body 1, and a door panel 3 is rotatably provided on the mounting opening 2 to close the mounting opening 2, and a first placement frame 4 is located in the cabinet body 1. Among them, the mounting opening 2 is opened on the front and back of the cabinet body 1, and the door panels 3 on each mounting opening 2 are double-door designs, which not only allows sufficient moving space for manual placement of instruments in the cabinet body 1, but also saves space occupied when the door panels 3 are opened. The first placement frame 4 is located inside the cabinet body 1 and is flush with the bottom surface of the mounting opening 2, so that instruments can be placed on the first placement frame 4 conveniently.

[0026] The disinfection device for disinfecting the instruments on the first placement frame 4 includes a fixed block 11 slidably arranged in the cabinet 1, and the fixed block 11 is symmetrically arranged with respect to the center of the cabinet 1. A sliding groove is provided on the side of the fixed block 11 close to the inner wall of the cabinet 1, and a slide rail matching the sliding groove of the fixed block 11 is provided on the inner wall of the cabinet 1, so that the fixed block 11 can slide in the cabinet 1. A support frame 6 and a first motor 12 are also provided on the fixed block 11, and the first motor 12 is connected to an external power supply. A loading circle 9 is also rotatably arranged between the two support frames 6, and a liquid spraying device is symmetrically arranged with respect to the center of the inner circle of the loading circle 9, and the liquid spraying device is arranged toward the center of the loading circle 9, so as to spray disinfectant on the instruments in the first placement frame 4. In order to realize the rotation of the loading circle 9, the first motor 12 is connected to the loading circle 9 through a transmission part. It should be noted that when the first placement frame 4 is in the object-carrying circle 9, the first motor 12 and the spray device can be started at the same time when the instrument is disinfected. The first motor 12 drives the object-carrying circle 9 to rotate back and forth through the transmission part. The spray device sprays disinfectant on the top and back surfaces of the instrument on the first placement frame 4 at the same time, and in the process of the object-carrying circle 9 driving the spray device to rotate, the spray device can also spray disinfectant on the side of the instrument, thereby achieving a comprehensive effect on the instrument, saving the work of manually turning over the instrument, improving the disinfection efficiency of the instrument, and making the instrument disinfection more comprehensive and uniform.

[0027] The transmission part used to connect the first motor 12 and the object-carrying circle 9 includes a first gear 13 provided on the first motor 12, an outer gear ring 10 sleeved on the object-carrying circle 9, and the first gear 13 meshes with the outer gear ring 10. The rotation of the first motor 12 will drive the first gear 13 to rotate, and the rotation of the first gear 13 will drive the outer gear ring 10 to rotate, and the outer gear ring 10 will also drive the connected object-carrying circle 9 to rotate. It should be noted that the first motor 12 can rotate forward and reverse, so that the nozzle 16 on the object-carrying circle 9 can reciprocate and spray disinfectant to each instrument on the first placement frame 4 for multiple times, so that the instrument disinfection is more thorough, and the sprayed disinfectant can also wash away impurities on the surface of the instrument, further improving the practicality of the disinfection device.

[0028] In order to make the object-carrying circle 9 rotate more smoothly on the support frame 6, the support frame 6 is composed of a rib plate 61 arranged on the fixed block 11, two support plates 62 detachably arranged on the rib plate 61, and two sets of limit wheels 63 rotatably arranged on the inner wall of each support plate 62, and the object-carrying circle 9 is supported between the two sets of limit wheels 63 of each support plate 62. When the first motor 12 drives the object-carrying circle 9 to rotate through the transmission part, the object-carrying circle 9 will rotate under the rotation of the limit wheels 63, so that the rotation is more stable and smooth. In order to facilitate the disassembly and assembly of the object-carrying circle 9 and the support frame 6, the support plate 62 and the rib plate 61 are set to be slidably connected, and protrusions are arranged at both ends of the rib plate 61, and a bidirectional threaded rod 7 is rotatably arranged between the two protrusions, and the bidirectional threaded rod 7 passes through the two support plates 62 and is threadedly connected with the two support plates 62, and hand wheels 8 are arranged at both ends of the bidirectional threaded rod 7. By turning the hand wheel 8, the hand wheel 8 drives the bidirectional threaded rod 7 to rotate, and the two support plates 62 threadedly connected to the bidirectional threaded rod 7 will move relative to each other on the rib plate 61. When the two support plates 62 move relatively away from each other, the limiting wheels 63 set on the two support plates 62 will also move relatively away from each other, and then the object-carrying ring 9 can be removed from between the limiting wheels 63 of the two support plates 62. Similarly, when installing the object-carrying ring 9, it is only necessary to place the object-carrying ring 9 between the limiting wheels 63 of the two support plates 62 and turn the hand wheel 8 so that the two support plates 62 move relatively close to each other.

[0029] like Figure 1 and Figure 3 As shown, the liquid spraying device includes a storage box 24 arranged on the outer wall of the cabinet 1, a spray pipe 16 arranged on the inner wall of the object-carrying circle 9, and the spray pipe 16 is connected with the liquid pump in the storage box 24 through a connecting pipe 25. When the liquid pump is working, the disinfectant in the storage box 24 will be transported to the spray pipe 16 through the connecting pipe 25, and then sprayed onto the instrument through the spray pipe 16 to complete the disinfection of the instrument. The connecting pipe 25 used to connect the spray pipe 16 and the liquid pump is a hose.

[0030] At the same time, a reciprocating device 14 is symmetrically arranged at the longitudinal center of the cabinet 1, and each reciprocating device 14 is connected to the fixed block 11. The reciprocating device 14 includes a screw 142 rotatably arranged on the cabinet 1, and a second motor 141 arranged on the outer wall of the cabinet 1. The second motor 141 is connected to the screw 142, and the screw 142 penetrates the corresponding fixed block 11 and is threadedly connected thereto. The second motor 141 is connected to an external power supply, and when the second motor 141 is working, it will drive the corresponding screw 142 to rotate, and when the screw 142 rotates, it will drive the fixed block 11 to move in the cabinet 1, and the fixed block 11 will also drive the object-carrying circle 9 and the liquid spraying device on the object-carrying circle 9 to move through the support frame 6, so that the liquid spraying device can further perform comprehensive disinfection on each instrument on the first placement frame 4, thereby improving the practicality of the disinfection device.

[0031] In order to collect and discharge the disinfectant sprayed by the spray device, a discharge part is provided in the cabinet 1, and the discharge part includes a collection tank 22 provided in the cabinet 1, and the collection tank 22 is located below the disinfection device, and a discharge pipe 23 is connected to the bottom surface of the collection tank 22. Among them, the collection tank 22 is a conical design with a large top and a small bottom, which can facilitate the collection and discharge of the disinfectant.

[0032] Preferably, a connecting frame 18 is further provided on the fixing block 11, and an inner gear ring 19 is provided on the connecting frame 18. A hanging plate 15 is provided on the inner wall of the carrier circle 9 at the position corresponding to the nozzle 16, and the nozzle 16 and the hanging plate 15 are rotatably arranged, and the nozzle 16 and the carrier circle 9 are connected by a spring 17. At the same time, a second gear 20 is rotatably arranged on the nozzle 16, and the second gear 20 is eccentrically arranged on the nozzle 16, and the second gear 20 is meshed with the inner gear ring 19. In order to facilitate the disassembly and assembly of the spring 17, a limit column 21 is obliquely provided on the nozzle 16 and the carrier circle 9, and the two limit columns 21 are coaxially arranged, and the spring 17 is sleeved on the two limit columns 21. When the carrier ring 9 drives the nozzle 16 to rotate through the hanging plate 15, the second gear 20 rotates under the action of the inner ring gear 19, and the nozzle 16 cooperates with the spring 17 to perform a reciprocating swing when the second gear 20 rotates, thereby expanding the spray range of the nozzle 16 during spraying, so that all instruments can be fully exposed to the disinfectant for disinfection.

[0033] As another preferred embodiment, a second placement frame 5 is provided in the cabinet 1, and a lifting device for driving the second placement frame 5 to move is provided in the cabinet 1, and the second placement frame 5 cooperates with the first placement frame 4. After the lifting device drives the second placement frame 5 to rise, the instrument placed on the first placement frame 4 can be lifted, so that the instrument is out of contact with the first placement frame 4, and then the liquid spraying device can spray disinfectant at the position where the instrument contacts the first placement frame 4 when moving to the initial position, so as to prevent the problem of incomplete disinfection of the instrument.

[0034] Specifically, the first placement frame 4 includes a first support rod 41 symmetrically arranged with respect to the longitudinal midline of the cabinet 1, and a plurality of first connecting rods 42 are spaced apart between the two first support rods 41. The second placement frame 5 includes a second support rod 51 symmetrically arranged with respect to the longitudinal midline of the cabinet 1, and a plurality of longitudinal rods 52 are spaced apart on the bottom surface of each second support rod 51, and the longitudinal rods 52 of the two second support rods 51 are connected by a second connecting rod 53. Moreover, each longitudinal rod 52 is located inside the first connecting rod 42, and the second connecting rod 53 and the first connecting rod 42 are staggered. Among them, the lifting device for driving the second placement frame 5 to move includes an electric push rod 56 arranged on the top surface of the cabinet 1, and a connecting plate 55 is provided at the telescopic end of the electric push rod 56, and a hoisting rod 54 is provided at both ends of the bottom surface of the connecting plate 55, and the hoisting rod 54 is connected to the second connecting rod 53. After the reciprocating device 14 drives the fixed block 11 to move once in the cabinet 1, the electric push rod 56 can be started, and the electric push rod 56 drives the first placement frame 4 on the hanging rod 54 to move upward through the connecting plate 55, and the second placement frame 5 will lift the equipment on the first placement frame 4, so that the equipment is out of contact with the first placement frame 4, and then the second motor 141 in the reciprocating device 14 drives the screw 142 to rotate in the opposite direction, so that the fixed block 11 moves to the initial direction, and during its movement, the liquid spraying device will disinfect the position where the equipment contacts the first placement frame 4, so as to achieve the effect of comprehensive disinfection of the equipment by the disinfection device, and also improve the practicality of the disinfection device. When the liquid spraying device has finished disinfecting the equipment, the electric push rod 56 lowers its second placement frame 5 to the initial position through the connecting plate 55 and the hanging rod 54, and then the equipment can be removed from the first placement frame 4.

[0035] Instructions for use: place the instrument on the first placement frame 4, then start the first motor 12, the second motor 141 and the liquid pump, the first motor 12 drives the loading circle 9 to rotate through the transmission part, the nozzle 16 set on the loading circle 9 through the hanging plate 15 begins to swing the reciprocating device 14 under the action of the second gear 20 and the inner gear ring 19, and the liquid pump transports the disinfectant to the nozzle 16 through the connecting pipe 25, and sprays it to the instrument on the first placement frame 4 through the nozzle 16, thereby completing the disinfection of the instrument.
