DETAILED DESCRIPTION

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] Reference Figure 1-Figure 8 A cleaning device for medical device maintenance includes a cleaning barrel 100 storing a cleaning medium, a side bracket 400 located at one side of the cleaning barrel 100 and arranged vertically, a cleaning mechanism 200 for receiving medical devices and cleaning the medical devices using the cleaning medium, and a drying mechanism 300 for drying the cleaned medical devices, wherein the cleaning mechanism 200 can achieve dead-angle cleaning, and the drying mechanism 300 can achieve dead-angle drying, thereby improving the cleaning effect of the medical devices.

[0035] Furthermore, a drain pipe 101 is provided at the bottom of the cleaning barrel 100, and a solenoid valve 102 is provided on the drain pipe 101. The cleaning medium can be a disinfectant, which can be directly poured into the cleaning barrel 100 from the barrel mouth. After cleaning, the solenoid valve 102 is opened to discharge the dirty cleaning medium.

[0036] 1. Cleaning mechanism 200:

[0037] Reference Figure 4-Figure 6 The cleaning mechanism 200 includes a traction assembly mounted on a side bracket 400 and a cleaning assembly located in the cleaning bucket 100 .

[0038] A guide rod is arranged vertically and close to the wall of the cleaning barrel 100 .

[0039] Reference Figure 5 and Figure 6 The cleaning assembly includes a supporting component, and the supporting component is arranged in two groups along the vertical direction.

[0040] The supporting component includes a sliding seat 203 that is slidably connected to the guide rod and a connecting ring 204 whose axis is vertically arranged and whose outer circular surface is connected to the sliding seat 203. A supporting rod 205 is provided on the inner circular surface of the connecting ring 204. Furthermore, the supporting rod 205 includes a cross bar 2052 horizontally located above the connecting ring 204. Both ends of the cross bar 2052 have side bars 2051 extending downward. The bottom of the side bar 2051 is fixedly connected to the inner circular surface of the connecting ring 204. An inclined surface is provided on the upper end of the cross bar 2052. Furthermore, a plurality of supporting rods 205 are arranged in an array along the horizontal direction, and the array direction of the supporting rods 205 is perpendicular to the extension direction of the cross bar 2052.

[0041] The supporting rods 205 in the two groups of supporting parts are arranged alternately, and when the supporting part located at the lower position moves in the vertical direction, the upper end surface of the supporting rod 205 in the supporting part located at the lower position can be higher or lower than the upper end surface of the supporting rod 205 in the supporting part located at the upper position.

[0042] When the upper end surfaces of the supporting rods 205 in the two groups of supporting components are located at the same horizontal height, the distance between the inclined surfaces of the corresponding supporting rods 205 in the two groups of supporting components decreases along the vertical direction from bottom to top.

[0043] A connecting arm 206 is connected to the sliding seat 203 in the supporting component below, and a cross seat 208 is rotatably mounted at the end of the connecting arm 206. The rotating shaft formed at the rotating mounting position forms a power connection with a motor 207 arranged on the connecting arm 206. A plurality of ultrasonic transducers 209 are distributed in an array on the cross seat 208, and the rotating shaft is coaxial with the connecting ring 204.

[0044] Reference Figure 4The traction assembly includes a traction component for traction sliding seat 203 to move on the guide rod, and two groups of traction components are correspondingly arranged. The traction component includes a traction seat 202 and a linear module 201 for driving the traction seat 202 to move in a vertical direction. The traction seat 202 and the sliding seat 203 are each embedded with a magnet on the side facing each other. The magnetic poles of the two magnets on the sides facing each other are opposite. Therefore, there is a magnetic adsorption force between the two. When the linear module 201 drives the traction seat 202 to move, based on the principle of magnetic coupling, the traction seat 202 will move with the sliding seat 203.

[0045] Furthermore, the linear module 201 includes a vertically arranged screw and a motor 3 for driving the screw to rotate. A nut is installed on the outside of the screw, and the nut is connected to the traction seat 202. The traction seat 202 and the side bracket 400 form a sliding guide fit along the vertical direction.

[0046] Working principle of cleaning mechanism 200:

[0047] Initially, the crossbar 2052 of the upper supporting component is higher than the crossbar 2052 of the lower supporting component, and the medical device is placed on the crossbar 2052 of the upper supporting component;

[0048] The two traction components operate simultaneously, respectively pulling the two supporting components to move downward simultaneously, so that the medical device is immersed in the cleaning medium of the cleaning bucket 100;

[0049] The ultrasonic transducer 209 is started and cooperates with the cleaning medium to clean the medical device. At the same time, the motor 207 drives the horizontal seat 208 to rotate around the axis of the rotating shaft, so that the ultrasonic transducer 209 is located under each part of the medical device in turn, thereby improving the cleaning effect;

[0050] After a preset time, the traction component corresponding to the supporting component located below is started, pulling the supporting component located below to move upward, thereby supporting the medical device through the cross bar 2052 of the supporting component located below. The advantage of this is that the two groups of supporting components alternately support the medical device, which can achieve comprehensive cleaning of the medical device without dead ends.

[0051] 2. Drying mechanism 300:

[0052] Reference Figure 4 , Figure 7 and Figure 8 The drying mechanism 300 includes a drying cover 301 coaxially located above the washing barrel 100 and connected to the side bracket 400. The upper end of the drying cover 301 is closed, the lower end is open, and the outer surface is provided with a plurality of avoidance air holes 302 in an array along the circumferential direction.

[0053] The upper end of the guide rod extends into the drying shell 301 and is connected to the closed end of the drying shell 301. Therefore, the supporting assembly and the medical device placed on the supporting assembly can be pulled into the drying shell 301 through the traction assembly.

[0054] A rotating arm 303 is rotatably mounted on the upper closed end of the drying shell 301, and a connecting shaft formed at the rotating mounting position is coaxial with the drying shell 301. The connecting shaft is dynamically connected to a motor 304 disposed on the side bracket 400. The end of the rotating arm 303 is located on one side of the outer cylindrical surface of the drying shell 301. A drying element 305 is disposed at the end of the rotating arm 303. The drying element 305 is used to provide hot air into the drying shell 301, thereby drying the medical device. Furthermore, the drying element 305 can be realized by using a fan technology combined with an electric heating technology, or other existing technologies can also be used, which will not be elaborated on.

[0055] Working principle of drying mechanism 300:

[0056] After the medical device is cleaned, the two pulling components operate simultaneously, pulling the two supporting components upwards respectively, thereby transferring the medical device into the drying housing 301;

[0057] Then, the drying element 305 is started, and the hot air generated will continue to pass through the drying housing 301. At the same time, the second motor 304 is started, driving the rotating arm 303 to rotate around the axis of the connecting shaft and rotating with the drying element 305. The two cooperate to achieve the drying process of the medical device.

[0058] In addition, during the drying process, the medical device is supported by the supporting member located at the top, and the cross bar 2052 of the supporting member located at the bottom is lower than the cross bar 2052 of the supporting member located at the top. In this way, a part of the hot air is directly blown to the side of the medical device to dry the side of the medical device, a part of the hot air flows from the upper surface of the medical device to dry the upper surface of the medical device, and a part of the hot air is guided by the inclined surface of the cross bar 2052 of the supporting member located at the bottom, flows upward, and dries the lower surface of the medical device. After a preset time, the positions of the two supporting members are changed, and the medical device is supported by the cross bar 2052 of the supporting member located at the bottom, and the inclined surface of the cross bar 2052 of the supporting member located at the top guides the hot air. In this way, the hot air can be blown to the medical device from all sides, so as to achieve comprehensive and dead-angle drying of the medical device.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention.
