Description

Technical Field

[0001] This invention relates to the field of sterilization cabinet technology, and more particularly to a medical device sterilization cabinet with auxiliary structures. Background Technology

[0002] A medical device sterilizer is a device used to kill various microorganisms on medical devices and ensure that they reach a sterile state. It is widely used in medical and health, scientific research and other fields. Sterilizers are required for the disinfection of medical devices in brain tumor departments.

[0003] Existing devices are inconvenient to move medical devices during the disinfection process, resulting in disinfection blind spots; they are also inconvenient to perform mobile, multi-directional disinfection of medical devices, leading to low disinfection efficiency. Summary of the Invention

[0004] This invention relates to a medical device sterilization cabinet with an auxiliary structure, which solves the problems of existing devices being inconvenient to move medical devices during the sterilization process, resulting in sterilization dead zones; and existing devices being inconvenient to move and sterilize medical devices in multiple directions during the sterilization process, resulting in low sterilization efficiency.

[0005] This invention provides a medical device sterilization cabinet with an auxiliary structure, specifically comprising: a sterilization cabinet; a disinfectant storage tank placed on the bottom surface of the inner wall of the sterilization cabinet, the disinfectant storage tank being filled with disinfectant liquid; symmetrically welded supports on the inner wall of the sterilization cabinet, each support having a base block placed on it; rotating shafts equidistantly rotating on the two base blocks, each rotating shaft having a worm gear welded on it; a worm rotating on the base block, the worm meshing with the worm gear; a first motor fixed on the base block, the output shaft of the first motor fixed on the worm; and a rubber tube attached to each rotating shaft, on which a medical device is placed.

[0006] Furthermore, grooves are equally spaced on the outer wall of each rubber tube, and the base block, rotating shaft, rubber tube, grooves, worm gear, worm and first motor together form the placement assembly.

[0007] Furthermore, a spray assembly is installed above the support in the disinfection cabinet. The spray assembly consists of a sliding rail, a seat, rubber bands, a spray pipe, a connecting rope, a winding machine, an electric cylinder, a liquid pump, and spray holes. The sliding rail is symmetrically fixed inside the disinfection cabinet, and the seat slides in the sliding rail. The spray pipe is fixed on the seat. A liquid pump is installed in the disinfectant storage tank, and the liquid pump's drain pipe is connected to the spray pipe.

[0008] Furthermore, two rubber bands are connected to the base, both of which are connected to the sliding track. A connecting rope is connected to the base, and a winding machine is fixed to the rear end of the disinfection cabinet. The connecting rope is connected to the winding shaft of the winding machine.

[0009] Furthermore, the nozzle is a cylindrical tubular structure, and spray holes are arranged in a fan-shaped array on the lower part of the outer wall of the nozzle. The fan-shaped array of spray holes is an extension of the nozzle spray.

[0010] Furthermore, a disinfection lamp is fixed on the sliding track, and the disinfection lamp is electrically connected to an external power supply. Two electric cylinders are symmetrically fixed on the inner wall of the disinfection cabinet, and the extended ends of the two electric cylinders are fixed on the sliding track.

[0011] Furthermore, a spray assembly and a disinfection lamp are also installed inside the disinfection cabinet, located below the support.

[0012] Furthermore, an auxiliary component is installed on the sliding rail described below. The auxiliary component consists of a shielding seat, a threaded rod, and a second motor. The shielding seat slides on the sliding rail and is located above the disinfection lamp. The shielding seat is a shielding component for the disinfection lamp.

[0013] Furthermore, the disinfection cabinet has a rotatable threaded rod that is threadedly connected to the shielding seat, and a second motor is fixed to the rear end face of the disinfection cabinet, with the output shaft of the second motor fixed to the threaded rod.

[0014] Furthermore, the rear end face of the disinfection cabinet is symmetrically welded with two support seats, both of which are concave structures. The support seats serve as the support components and carrying components of the disinfection cabinet.

[0015] This invention provides a medical device sterilization cabinet with an auxiliary structure, which has the following beneficial effects: In eliminating blind spots during disinfection, the placement components of the sterilization cabinet play a crucial role. The rotating shaft on the base is driven by a first motor through a worm gear transmission, which moves the attached rubber tube and the placed medical devices. At the same time, the grooves on the outer wall of the rubber tube increase the frictional resistance with the medical devices, preventing slippage and ensuring that the position of the medical devices is dynamically adjusted during the disinfection process. In conjunction with the spray components and disinfection lamps installed above and below the tray inside the sterilization cabinet, the medical devices can be fully covered, especially for easily overlooked areas such as the bottom, thoroughly eliminating blind spots that are difficult to reach with traditional equipment.

[0016] This device features a highly targeted design for its spray assembly, which expands the disinfection range and improves efficiency. The spray nozzle moves back and forth by reciprocating the connecting rope through a winding machine. Combined with the fan-shaped array of spray holes below the nozzle, the spray range is doubled. At the same time, the electric cylinder drives the sliding track to adjust the height of the spray nozzle and the disinfection lamp, further expanding the coverage area and allowing the disinfectant to contact medical devices more evenly and widely. The liquid pump efficiently delivers the disinfectant to the spray nozzle, which, together with the disinfection lamp, forms a dual disinfection mode of spraying and light irradiation, greatly improving disinfection efficiency and shortening the overall disinfection time.

[0017] In terms of ensuring equipment safety and ease of use, the auxiliary components on the lower sliding track can adjust the position of the shielding seat by driving the threaded rod with the second motor. During spraying, the shielding lamp is blocked to prevent short circuits caused by liquid contact, thus ensuring safe operation of the equipment. The concave support seat at the rear of the disinfection cabinet not only keeps the equipment away from the wall when placed to prevent moisture damage, but also serves as a carrying tool, making it easy for operators to hold and move, thus improving the convenience of equipment handling.

[0025] Example 1: Please refer to Figures 1 to 9 : This invention proposes a medical device sterilization cabinet with auxiliary structures, comprising: a sterilization cabinet 1; a disinfectant storage tank 103 placed on the bottom surface of the inner wall of the sterilization cabinet 1, the disinfectant storage tank 103 being filled with disinfectant liquid; symmetrically welded supports 101 on the inner wall of the sterilization cabinet 1, each support 101 having a base block 201 placed on it; rotating shafts 202 equidistantly rotating on the two base blocks 201; a worm gear 205 welded to each rotating shaft 202; a worm 206 rotating on the base block 201, the worm 206 meshing with the worm gear 205; and the base blocks 201... A first motor 207 is fixed on 01, and the output shaft of the first motor 207 is fixed on the worm gear 206. A rubber tube 203 is attached to each rotating shaft 202, and a medical device 3 is placed on the rubber tube 203. During the disinfection process, the first motor 207 is started, and the first motor 207 drives the worm gear 206 to rotate. Under the meshing transmission of the worm gear 206 and the worm wheel 205, the rotating shaft 202 can be rotated. At this time, the rubber tube 203 drives the medical device 3 to move. Through the displacement of the medical device 3, the disinfection dead corners can be eliminated.

[0026] Each rubber tube 203 has grooves 204 evenly spaced on its outer wall. The base block 201, rotating shaft 202, rubber tube 203, grooves 204, worm gear 205, worm 206 and first motor 207 together form the placement assembly 2. The rubber tube 203 and grooves 204 can increase the frictional resistance between the rubber tube and the medical device 3, thereby avoiding slippage that could affect the displacement of the medical device 3.

[0027] The disinfection cabinet 1 is equipped with a spray assembly 4 above the support 101. The spray assembly 4 consists of a sliding rail 401, a seat 402, a rubber band 403, a spray pipe 404, a connecting rope 405, a winding machine 406, an electric cylinder 407, a liquid pump 408, and a spray hole 409. The sliding rail 401 is symmetrically fixed inside the disinfection cabinet 1. The seat 402 slides inside the sliding rail 401. The spray pipe 404 is fixed on the seat 402. The liquid pump 408 is installed inside the disinfection liquid storage tank 103. The drain pipe of the liquid pump 408 is connected to the spray pipe 404.

[0028] The base 402 is connected to two rubber bands 403, both of which are connected to the sliding rail 401. A connecting rope 405 is connected to the base 402. A winding machine 406 is fixed to the rear end of the disinfection cabinet 1. The connecting rope 405 is connected to the winding shaft of the winding machine 406. When spraying disinfectant, the liquid pump 408 is started, and the liquid pump 408 delivers the disinfectant liquid to the spray pipe 404 for spraying. At the same time, the winding machine 406 is driven to rotate back and forth. When the winding machine 406 rotates back and forth, it can continuously wind up the connecting rope 405. At this time, the reciprocating movement of the spray pipe 404 is realized, thereby expanding the spraying range.

[0029] The nozzle 404 is a cylindrical tubular structure. Spray holes 409 are arranged in a fan-shaped array on the lower part of the outer wall of the nozzle 404. The fan-shaped array of spray holes 409 is an extension of the spraying of the nozzle 404. During the spraying process, the spraying range can be further expanded through the fan-shaped array of spray holes 409, thereby improving the spraying disinfection efficiency.

[0030] The disinfection lamp 5 is fixed on the sliding track 401 and is electrically connected to an external power source. Two electric cylinders 407 are symmetrically fixed on the inner wall of the disinfection cabinet 1. The extended ends of the two electric cylinders 407 are fixed on the sliding track 401. During disinfection, the power supply of the disinfection lamp 5 is turned on, and the medical device 3 can be disinfected by irradiation through the disinfection lamp 5. The two electric cylinders 407 are also driven to extend, which can realize the height adjustment of the disinfection lamp 5 and the spray nozzle 404, further expanding the disinfection range.

[0031] The disinfection cabinet 1 is also equipped with a spray assembly 4 and a disinfection lamp 5 located below the support 101. The spray assembly 4 and the disinfection lamp 5 below can disinfect the bottom of the medical device 3, eliminating disinfection dead corners.

[0032] An auxiliary component 6 is installed on the lower sliding rail 401. The auxiliary component 6 consists of a shielding seat 601, a threaded rod 602, and a second motor 603. The shielding seat 601 slides on the sliding rail 401 and is located above the disinfection lamp 5. The shielding seat 601 is a shielding component for the disinfection lamp 5. By shielding the disinfection lamp 5 with the shielding seat 601, the spray liquid can be prevented from contacting the disinfection lamp 5, thereby preventing short circuits.

[0033] The disinfection cabinet 1 has a rotating threaded rod 602, which is threadedly connected to the shielding seat 601. A second motor 603 is fixed to the rear end face of the disinfection cabinet 1, and the output shaft of the second motor 603 is fixed to the threaded rod 602. When the bottom of the medical device 3 is disinfected by the disinfection lamp 5 below, the second motor 603 is driven to rotate, which in turn drives the threaded rod 602 to rotate. Under the threaded drive of the threaded rod 602, the position of the shielding seat 601 can be adjusted, thus preventing the shielding seat 601 from affecting the disinfection of the bottom of the medical device 3 by the disinfection lamp 5 below.

[0034] Example 2, based on Example 1, such as Figures 1-9 As shown, two support seats 102 are symmetrically welded to the rear end face of the disinfection cabinet 1. Both support seats 102 are concave structures. The support seats 102 are the support components and carrying components of the disinfection cabinet 1. When placed, the two support seats 102 are in contact with the wall. This can prevent the device from getting damp. When carrying, holding the upper support seat 102 makes it convenient to carry the device.

[0035] The working principle of this embodiment is as follows: First, ensure the disinfection cabinet 1 is placed stably. Then, check the amount of disinfectant liquid in the disinfectant storage tank 103. If the liquid is insufficient, add enough disinfectant liquid. Next, open the door of the disinfection cabinet 1 and place the medical devices 3 to be disinfected one by one onto the rubber tube 203, ensuring that the medical devices 3 are stably placed in the groove 204 on the outer wall of the rubber tube 203. After placement, close the door of the disinfection cabinet 1. Then, connect the external power supply to the entire device. First, start the first motor 207. The output shaft of the first motor 207 will drive the worm gear 206 to rotate on the base block 201. Since the worm gear 206 meshes with the worm wheel 205, the worm wheel 205 will rotate with the worm gear 206, driving the rotating shaft 202 between the two base blocks 201. When the rotating shaft 202 rotates, it drives the rubber tube 203 to rotate as well, thereby causing the medical device 3 on the rubber tube 203 to shift. Then, the liquid pump 408 in the disinfectant storage tank 103 is activated, and the liquid pump 408 delivers the disinfectant liquid from the storage tank 103 to the spray nozzle 404 through the drain pipe. The disinfectant liquid is then sprayed out from the fan-shaped array of spray holes 409 on the lower outer wall of the spray nozzle 404. Simultaneously, the winding machine 406 at the rear end of the disinfection cabinet 1 is activated, causing the winding machine 406 to reciprocate. During reciprocating rotation, the winding machine 406 continuously winds and releases the connecting rope 405. The movement of the connecting rope 405 causes the seat 402 to slide back and forth within the sliding track 401. The sliding of the seat 402 drives... The spray nozzle 404 moves back and forth together; if the height of the spray nozzle 404 needs to be adjusted, the two electric cylinders 407 symmetrically fixed on the inner wall of the disinfection cabinet 1 can be driven to extend or retract the protruding ends of the electric cylinders 407. The movement of the electric cylinders 407 drives the sliding rail 401 to move up and down, thereby driving the spray nozzle 404 to adjust its height; while spraying disinfection, the disinfection lamp 5 is connected to the external power supply to start working; if the height of the disinfection lamp 5 needs to be adjusted, the two electric cylinders 407 are also driven to move the sliding rail 401 up and down, and the disinfection lamp 5 fixed on the sliding rail 401 will adjust its height accordingly; when it is necessary to use the spray assembly 4 and the disinfection lamp 5 located below the support 101 in the disinfection cabinet 1, follow the instructions. The same operation method described above is used to start the liquid pump 408, winding machine 406 and disinfection lamp 5 in the lower spray assembly 4. At the same time, the height of the lower sliding track 401 can be adjusted by driving the corresponding electric cylinder 407, thereby adjusting the height of the lower spray pipe 404 and disinfection lamp 5. When it is necessary to use the lower disinfection lamp 5 to irradiate and disinfect the bottom of the medical device 3, the second motor 603 at the rear end of the disinfection cabinet 1 is started. The output shaft of the second motor 603 drives the threaded rod 602 to rotate on the disinfection cabinet 1. Since the threaded rod 602 is threadedly connected to the shielding seat 601, the rotation of the threaded rod 602 will drive the shielding seat 601 to slide on the lower sliding track 401, moving the shielding seat 601 to a position that does not block the irradiation path of the lower disinfection lamp 5.When the lower disinfection lamp 5 is no longer needed and spraying is required, restart the second motor 603 to reverse the rotation of the threaded rod 602, causing the shielding seat 601 to slide to a position above the lower disinfection lamp 5, thus shielding the lower disinfection lamp 5. After the entire disinfection process is completed, first turn off the first motor 207, liquid pump 408, winding machine 406, disinfection lamp 5, and second motor 603, disconnect the device from the external power supply, and wait for the medical device 3 inside the disinfection cabinet 1 to cool down and the surface disinfection liquid to be basically dry. Then, open the cabinet door of the disinfection cabinet 1 and remove the disinfected medical device 3 from the rubber tube 203. If the device needs to be carried later, it can be moved by holding the upper one of the two symmetrically welded support seats 102 at the rear end of the disinfection cabinet 1.
