Description

Technical Field

[0001] This utility model relates to the field of high-pressure steam sterilization technology, specifically a sterilization device for replacement parts used in joint replacement. Background Technology

[0002] Joint prosthesis replacements require re-sterilization in certain special circumstances, such as when a joint prosthesis needs to be removed and reimplanted due to infection. For prosthesis replacements that have already been implanted and need to be removed for reuse, the sterilization process is very strict. It is necessary to ensure the complete removal of all potential pathogens while ensuring that the prosthetic material is not damaged. Autoclaving is a commonly used and reliable sterilization method. It is a proven and feasible method for most medical devices and components, including joint replacement replacements. This sterilization method can effectively kill most microorganisms, ensuring the safety and sterility of the replacement.

[0003] For example, authorization announcement number CN217091520U discloses a high-pressure steam sterilizer, including a cabinet body. Both sides of the outer surface of the cabinet body are fixedly connected to disinfectant tanks. An injection port is provided at the top of the disinfectant tanks. A heating element is fixedly installed inside the disinfectant tanks. Two sets of conduits are symmetrically arranged inside the cabinet body. One end of each set of conduits extends into the interior of the disinfectant tanks, and a steam nozzle is fixedly installed at the other end of each set of conduits. In this invention, when sterilizing the surface of objects inside the sterilizer, a motor drives a drive wheel to rotate. The rotation of the drive wheel drives a rotating rod to rotate, which in turn causes the objects inside the disc to rotate in a circular motion. This allows the steam emitted from the steam nozzles to sterilize the objects from all sides, reducing sterilization dead zones, improving the effectiveness of the device, and making operation more convenient and practical.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Although this type of high-pressure steam sterilizer allows the steam from the steam nozzles to sterilize objects from all angles, reducing sterilization dead spots, there are certain limitations in its use. When the high-temperature steam enters the cabinet, it rises and adheres to the top of the inner wall, accumulating into water droplets that fall onto the surface of the items being sterilized. These water droplets do not evaporate quickly, and if users use external tools to wipe or dry the items, secondary contamination can easily occur. Natural air drying, on the other hand, leads to low sterilization efficiency. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a disinfection device for replacement parts of joint replacement, which has the advantage of easy protection. It solves the problem that after high-temperature steam enters the cabinet, it rises as a whole and adheres to the top of the inner wall of the cabinet, accumulating into water droplets that fall onto the surface of the disinfected items. These water droplets do not evaporate in a short time, and users can easily cause secondary pollution by wiping or drying the disinfected items with external tools. Natural air drying leads to low disinfection efficiency, thus limiting its use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disinfection device for replacement parts in joint replacement, comprising a disinfection cabinet body, a disinfectant tank, a steam nozzle, and a rotating mechanism. The disinfectant tank is fixedly installed on the left and right sides of the disinfection cabinet body, and the steam nozzle is fixedly installed inside the disinfectant tank. The rotating mechanism includes a servo motor, which is fixedly installed on the top of the disinfection cabinet body. A transmission rod is fixedly connected to the output end of the servo motor, and a fixing ring is fixedly connected to the surface of the transmission rod. Three fixing rings are arranged at equal intervals. Placement plates are fixedly connected to the left and right sides of the surface of each fixing ring. A flow guide plate is fixedly connected to the front side of the top of the inner wall of the disinfection cabinet body, and the rear side of the flow guide plate is fixedly connected to the top of the rear side of the inner wall of the disinfection cabinet body. The flow guide plate is inclined. A protective mechanism is fixedly connected to the rear side of the bottom of the inner wall of the disinfection cabinet body, and an adjustment mechanism is fixedly connected to the outer side of the placement plate.

[0008] As a preferred embodiment of this utility model, the protective mechanism includes a splash guard, and a water outlet pipe is connected to the bottom right side of the inner wall of the disinfection cabinet body, with a sealing plug inserted into the inner wall of the water outlet pipe.

[0009] In a preferred embodiment of this utility model, the adjusting mechanism includes a fixed plate, and a connecting seat is movably connected to the rear side of the fixed plate via a pivot pin. An L-shaped rod is fixedly connected to both the front and rear sides of the outer side of the connecting seat.

[0010] As a preferred embodiment of this utility model, a screw is provided on the front side of the connecting seat. One end of the screw near the fixing plate passes through the connecting seat and the fixing plate in sequence and extends into the interior of the fixing plate. The screw is threadedly connected to the connecting seat and the fixing plate, and a handwheel is fixedly connected to the other end of the screw.

[0011] As a preferred embodiment of this utility model, two crossbars are fixedly connected to the inner side of the L-shaped rod, and a surrounding plate is fixedly connected to the front and rear sides of the top of the placement plate, and a diagonal frame is fixedly connected to the inner side of the L-shaped rod.

[0012] As a preferred embodiment of this utility model, a support platform is fixedly connected to the bottom of the inner wall of the disinfection cabinet body, and the end of the transmission rod away from the servo motor is movably connected to the top of the support platform through a bearing. A timer is fixedly installed on the front side of the disinfection cabinet body, and a controller is fixedly installed on the top of the front side of the disinfection cabinet body. Both the servo motor and the timer are electrically connected to the controller through wires.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a diversion plate, can divert the water droplets formed by high-temperature steam to the rear side of the inner wall of the disinfection cabinet, thereby preventing water droplets from falling onto the surface of the joint replacement parts. This solves the problem that after the high-temperature steam enters the cabinet, it rises as a whole and adheres to the top of the inner wall of the cabinet, forming water droplets that fall onto the surface of the disinfected items. The water droplets do not evaporate in a short time, and the user's use of external tools to wipe or dry the disinfected items can easily cause secondary pollution. Natural air drying leads to low disinfection efficiency, thus limiting its use. This invention achieves a convenient protective effect.

[0015] 2. By setting up a protective mechanism, the splash guard can prevent falling water droplets from splashing onto the top of the placement plate. By pulling out the sealing plug, the falling water droplets can be gathered into a water flow and flow out of the disinfection cabinet body through the water outlet pipe.

[0016] 3. By setting an adjustment mechanism, the fixed plate can limit the movement of the connecting seat through the shaft pin, so that the user can easily flip and adjust the connecting seat and the L-shaped rod. The connecting seat and the L-shaped rod can provide tilt support for the disinfected joint replacement part. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a disinfection device for replacement parts of joint replacement, including a disinfection cabinet body 1, a disinfectant tank 2, a steam nozzle 3, and a rotating mechanism 4. The disinfectant tank 2 is fixedly installed on the left and right sides of the disinfection cabinet body 1, and the steam nozzle 3 is fixedly installed on the inner side of the disinfectant tank 2. The rotating mechanism 4 includes a servo motor 41, which is fixedly installed on the top of the disinfection cabinet body 1. A transmission rod 42 is fixedly connected to the output end of the servo motor 41. A fixing ring 43 is fixedly connected to the surface of the transmission rod 42. Three fixing rings 43 are provided and are evenly distributed. Placement plates 44 are fixedly connected to the left and right sides of the surface of the fixing rings 43. A diversion plate 5 is fixedly connected to the front side of the top of the inner wall of the disinfection cabinet body 1. The rear side of the diversion plate 5 is fixedly connected to the top of the rear side of the inner wall of the disinfection cabinet body 1. The diversion plate 5 is inclined. A protective mechanism 6 is fixedly connected to the rear side of the bottom of the inner wall of the disinfection cabinet body 1. An adjustment mechanism 7 is fixedly connected to the outer side of the placement plate 44.

[0024] refer to Figure 2 The protective mechanism 6 includes a splash guard 61, and a water outlet pipe 62 is connected to the bottom of the right side of the inner wall of the disinfection cabinet body 1. A sealing plug 63 is inserted into the inner wall of the water outlet pipe 62.

[0025] As a technical optimization of this utility model, by setting the protective mechanism 6, the splash guard 61 can prevent falling water droplets from splashing onto the top of the placement plate 44. By pulling out the sealing plug 63, the falling water droplets can be gathered into a water flow and flow out of the disinfection cabinet body 1 through the water outlet pipe 62.

[0026] refer to Figure 4The adjustment mechanism 7 includes a fixed plate 71, and a connecting seat 72 is movably connected to the rear side of the fixed plate 71 via a shaft pin. L-shaped rods 73 are fixedly connected to the front and rear sides of the outer side of the connecting seat 72.

[0027] As a technical optimization of this utility model, by setting the adjustment mechanism 7, the fixing plate 71 can limit the movement of the connecting seat 72 through the shaft pin, so that the user can easily flip and adjust the connecting seat 72 and the L-shaped rod 73. The connecting seat 72 and the L-shaped rod 73 can provide tilt support for the disinfected joint replacement part.

[0028] refer to Figure 4 A screw 8 is provided on the front side of the connecting seat 72. One end of the screw 8 near the fixing plate 71 passes through the connecting seat 72 and the fixing plate 71 in sequence and extends into the interior of the fixing plate 71. The screw 8 is threadedly connected to the connecting seat 72 and the fixing plate 71. A handwheel 9 is fixedly connected to the other end of the screw.

[0029] As a technical optimization of this utility model, by setting a screw 8 and a handwheel 9, the screw 8 can position the connecting seat 72. When it is necessary to adjust the angle of the connecting seat 72, first rotate the handwheel 9 to drive the screw 8 to rotate so that it is disengaged from the inside of the fixing plate 71. After the adjustment is completed, rotate the screw 8 in the opposite direction to screw it back into the inside of the fixing plate 71 to position the connecting seat 72.

[0030] refer to Figure 4 Two crossbars 10 are fixedly connected to the inner side of the L-shaped rod 73. The front and rear sides of the top of the placement plate 44 are fixedly connected to the surrounding plate 11. The inner side of the L-shaped rod 73 is fixedly connected to the diagonal bracket 12.

[0031] As a technical optimization of this utility model, by setting up a crossbar 10, a surrounding plate 11 and a diagonal frame 12, the crossbar 10 can improve the support effect of the L-shaped rod 73 on the joint replacement part, the diagonal frame 12 can limit the tilted placement of the joint replacement part, and the surrounding plate 11 can improve the protection effect of the placement plate 44 on the joint replacement part.

[0032] refer to Figure 1 and Figure 2 A support platform 13 is fixedly connected to the bottom of the inner wall of the disinfection cabinet body 1. The end of the transmission rod 42 away from the servo motor 41 is movably connected to the top of the support platform 13 through a bearing. A timer 14 is fixedly installed on the front side of the disinfection cabinet body 1. A controller 15 is fixedly installed on the top of the front side of the disinfection cabinet body 1. The servo motor 41 and the timer 14 are both electrically connected to the controller 15 through wires.

[0033] As a technical optimization of this utility model, by setting up a support platform 13, a timer 14 and a controller 15, the support platform 13 can limit the movement of the transmission rod 42, the timer 14 makes it easy for the user to control the disinfection time of the joint replacement parts, a control valve is installed on the steam nozzle 3, a heating element is installed inside the disinfectant tank 2 and is electrically connected to the controller 15 through a wire, and the controller 15 makes it easy for the user to operate the servo motor 41, the timer 14, the control valve and the heating element.

[0034] The working principle and usage process of this utility model are as follows: First, open the cabinet door of the disinfection cabinet body 1. Then, rotate the handwheel 9 to drive the screw 8 to rotate, causing it to disengage from the inside of the fixing plate 71. Next, adjust the connecting seat 72 according to the required size of the replacement joint. At this time, the L-shaped rod 73, the crossbar 10, and the inclined bracket 12 rotate synchronously with the connecting seat 72. Then, place the replacement joint on the top of the placement plate 44, with the other end of the replacement joint leaning against the surface of the crossbar 10. At this time, the inclined bracket 12 and the surrounding plate 11 can limit and protect the replacement joint. The inclined replacement joint has a larger contact surface with the outside, improving the disinfection effect. After placement, close the cabinet door, then open the control valve of the steam nozzle 3 through the controller 15, and start the disinfection liquid tank 2. The internal heating element heats the disinfectant solution inside the disinfectant tank 2. The high-temperature steam generated by the heating is sprayed out through the steam nozzle 3 to disinfect the joint replacement parts inside the disinfection cabinet body 1. Then, the controller 15 starts the servo motor 41, which drives the transmission rod 42 to rotate. The rotation of the transmission rod 42 can drive the fixing ring 43 and the placement plate 44 to rotate, thereby improving the disinfection efficiency of the joint replacement parts. At this time, the steam rising to the bottom of the diversion plate 5 can gather into water droplets and flow down its surface. The anti-splash plate 61 can prevent the falling water droplets from splashing onto the top of the placement plate 44, providing good protection. After disinfection, the sealing plug 63 is pulled out, allowing the falling water droplets to gather into a water flow and flow out of the disinfection cabinet body 1 through the water outlet pipe 62.

[0035] In summary, this joint replacement component disinfection device, by setting a diversion plate 5, can divert water droplets formed by high-temperature steam to the rear side of the inner wall of the disinfection cabinet body 1, thereby preventing water droplets from falling onto the surface of the joint replacement component. This solves the problem that after the high-temperature steam enters the cabinet, it rises as a whole and adheres to the top of the inner wall of the cabinet, forming water droplets that fall onto the surface of the disinfected items. The water droplets do not evaporate in a short time, and the user's use of external tools to wipe or dry the disinfected items can easily cause secondary pollution. Natural air drying leads to low disinfection efficiency, thus limiting its use.
