Compared with the medical device disinfection equipment of the prior art, the installation work before disinfection and the removal work after disinfection are shorter and more convenient on the premise of completing the disinfection work of multiple medical devices, and the disinfection efficiency is further improved.

[0022] Furthermore, by arranging the first supporting assembly and the second supporting assembly in a spiral shape in the vertical direction, any two medical devices are not on the same horizontal plane. Therefore, during the disinfection process, there is no situation where one medical device blocks the disinfectant from flowing to the adjacent medical device. Further, by providing a spiral stirring blade, multiple medical devices in the same vertical position will not block the flow of disinfectant. After starting the motor, the motor drives the mounting base and the stirring blade to rotate reciprocatingly, so that during the entire disinfection process, the disinfectant is in a spiral state as a whole and the spiral direction is constantly changed, thereby enhancing the disinfection effect on the medical device.

[0023] Furthermore, by fixing the upper end of the stirring blade to the connecting ring, and the connecting ring can slide up and down, during the disinfection process, as the rotation direction of the stirring blade continues to change, the pitch of the stirring blade continues to increase and decrease, thereby changing the distance between the medical device and the stirring blade above it and the distance between the medical device and the stirring blade below it. When the water flow rate on the upper and lower sides of the medical device is different, there is a difference in flow rate, thereby forming a water flow from bottom to top or from top to bottom. During the entire disinfection process, the water flow is spiral as a whole and constantly switches its rotation direction. The water between the two layers of stirring blades flows vertically and constantly switches its flow direction, flushing the medical device from multiple angles, further optimizing the disinfection effect.

[0040] The mounting base 200 is coaxially mounted in the disinfection chamber 110 with the disinfection barrel 100, and the mounting base 200 can rotate relative to the disinfection barrel 100. The mounting base 200 is detachably connected to a driving member, and the driving member is used to drive the mounting base 200 to rotate alternately forward and reverse. The mounting base 200 is magnetically connected to the driving block 130, and the driving member is a motor 210, and the output end of the motor 210 is connected to the driving block 130;

[0041] A plurality of mounting frames 300 are provided, and the plurality of mounting frames 300 are evenly distributed around the circumference of the disinfection barrel 100 and are arranged in the disinfection chamber 110; each mounting frame 300 includes a mounting shaft 310, which is vertically arranged and fixedly connected to the mounting base 200 at its lower end, and each mounting shaft 310 is provided with a receiving groove 311;

[0042] The supporting mechanism 400 is provided in plurality, and one supporting mechanism 400 is installed on each mounting shaft 310. The supporting mechanism 400 includes a first supporting assembly and a second supporting assembly; the first supporting assembly is located below the second supporting assembly; the second supporting assembly can be radially movably installed in the receiving groove 311 along the mounting shaft 310, and the second supporting assembly has a stowed state and an unfolded state; when the second supporting assembly is in the stowed state, the second supporting assembly is received in the receiving groove 311, and when the second supporting assembly is in the unfolded state, the second supporting assembly extends out of the receiving groove 311;

[0043] There are multiple first adjustment mechanisms 500, and each mounting shaft 310 is equipped with a first adjustment mechanism 500. The first adjustment mechanism 500 is connected to the first supporting assembly and the second supporting assembly. The first adjustment mechanism 500 is used to switch the second supporting assembly connected to it to an expanded state when the first supporting assembly connected to it is under pressure.

[0044] When the medical device 700 needs to be disinfected, the mounting base 200 is separated from the driving member, and the mounting base 200 and the multiple mounting racks 300 mounted thereon are taken out from the disinfection chamber 110. In the initial state, the second supporting assembly is in a retracted state, which will not affect the vertical sliding of the medical device 700 on the mounting shaft 310; the medical device 700 is sleeved on the mounting shaft 310 from the upper end of the mounting shaft 310, and the medical device 700 moves along the axial direction of the mounting shaft 310 under the action of gravity; when the medical device 700 contacts the first supporting assembly on the mounting rack 300, pressure is applied to the first supporting assembly under the action of gravity, and at this time the first adjusting mechanism 500 switches the second supporting assembly located on the same mounting shaft 310 as the pressurized first supporting assembly to an expanded state (such as Fig. 9 , Fig.11 As shown in FIG. 3 ), at this time, the second supporting component extends out of the receiving groove 311 and can be used to support the medical device 700. At this time, the second medical device 700 can be sleeved on the mounting shaft 310 from above the mounting shaft 310. Each mounting frame 300 can be equipped with at least two medical devices 700, thereby improving the efficiency of sterilizing the medical devices 700.

[0045] After the medical devices 700 are installed on all the mounting frames 300, the mounting base 200 and the mounting frames 300 fixedly connected thereto are placed in the disinfection chamber 110, and the mounting base 200 is connected to the driving member; thereafter, the driving member is started, and the driving member drives the mounting base 200 to rotate back and forth, thereby completing the disinfection of the medical devices 700.

[0046] After the disinfection work is completed, the mounting base 200 is separated from the driving member again, and then the mounting base 200, the mounting frame 300 thereon and the medical device 700 are taken out of the disinfection chamber 110. After taking them out, the mounting base 200 and the mounting frame 300 are inverted, and the medical device 700 moves away from the mounting base 200 under the action of gravity. At this time, the first supporting assembly no longer receives the pressure of the medical device 700. At this time, the first adjustment mechanism 500 drives the second supporting assembly connected thereto to switch to a retracted state, and the medical device 700 on the mounting shaft 310 can naturally move along the axis of the mounting shaft 310 under the action of gravity, away from the mounting base 200. When the medical device 700 is detached from the mounting shaft 310, the disassembly of the disinfected medical device 700 is completed.

[0047] Compared with the disinfection equipment in the prior art, the present invention has a shorter installation period before disinfection and a shorter and more convenient dismantling period after disinfection, while completing the disinfection of multiple medical devices 700, thereby further improving the disinfection efficiency.

[0048] In a further embodiment, Figure 7 , Figure 8As shown, each mounting shaft 310 is provided with a receiving groove 311, the first supporting assembly is a supporting tray 410, and the second supporting assembly includes a plurality of supporting plates 420, the supporting plates 420 are fan-shaped, and the plurality of supporting plates 420 are evenly distributed along the circumference of the mounting shaft 310, and can be installed in the receiving groove 311 to be radially movable along the mounting shaft 310, and the first adjusting mechanism 500 is used to move the supporting plates 420 radially outward along the mounting shaft 310 when the supporting tray 410 is subjected to pressure.

[0049] When the medical device 700 needs to be sterilized, the mounting base 200 is separated from the driving member, and the mounting base 200 and the plurality of mounting brackets 300 mounted thereon are taken out of the sterilization chamber 110. In the initial state, the support plate 420 is received in the receiving groove 311, and the peripheral wall of the support plate 420 is flush with the peripheral wall of the mounting shaft 310. Fig.10 As shown, it will not affect the vertical sliding of the medical device 700 on the mounting shaft 310; thereafter, the medical device 700 is sleeved on the mounting shaft 310 from the upper end of the mounting shaft 310, and the medical device 700 moves downward under the action of gravity; when the medical device 700 contacts the supporting tray 410, under the action of gravity, pressure is applied to the supporting tray 410, and the first adjustment mechanism 500 causes the supporting plate 420 located above the supporting tray 410 to move radially outward along the mounting shaft 310 and extend out of the accommodating groove 311, which can be used to support the medical device 700. At this time, the second medical device 700 can be sleeved on the mounting shaft 310 from the upper side of the mounting shaft 310.

[0050] In a further embodiment, Figure 8 , Fig. 9As shown, a plurality of vertical first slide grooves 312 are provided on the peripheral wall of the installation shaft 310, and the plurality of first slide grooves 312 are uniformly distributed along the circumference of the installation shaft 310; an annular groove 313 is provided at the lower end of the installation shaft 310, and the bearing tray 410 can be installed in the annular groove 313 movably up and down, and a first support assembly is provided at the lower end of the bearing tray 410, and the first support assembly is used to make the bearing tray 410 have a tendency to maintain a preset height when not under pressure; the first adjustment mechanism 500 includes a plurality of first adjustment units 510, and the plurality of first adjustment units 510 are uniformly distributed along the circumference of the installation shaft 310; the first adjustment unit 510 includes a first rack 511, a transmission shaft 512, a second rack 513 and a connecting rod 514; the first rack The rack 511 extends in the vertical direction, and the lower end is fixedly connected to the supporting tray 410; the transmission shaft 512 is horizontally arranged, and a hinge hole 314 is opened on the mounting shaft 310, and the transmission shaft 512 is rotatably installed in the hinge hole 314, and the transmission shaft 512 is synchronously rotatably installed with a first gear 516 and a second gear 517, and the first gear 516 is meshed with the first rack 511; the second rack 513 is horizontally arranged, and can be radially moved along the mounting shaft 310.

The first rack 511 slides downward, and the first gear 516 rotates. When the first gear 516 rotates, it drives the transmission shaft 512 and the second gear 517 to rotate synchronously. The rotation of the second gear 517 drives the second rack 513 to move radially outward along the installation shaft 310, thereby driving the connecting rod 514 and the supporting plate 420 to move outward synchronously and extend out of the accommodating groove 311, which can be used to support the medical device 700. At this time, the second medical device 700 can be put on the installation shaft 310 from the top of the installation shaft 310.

[0052] In a further embodiment, Figure 7 , Figure 8As shown, a slider 422 is fixedly connected to the inner end of the support plate 420, and the slider 422 is installed on the connecting rod 514 so as to be movable up and down. A second support assembly is arranged at the lower end of the support plate 420, and the second support assembly is used to make the support plate 420 tend to maintain a preset height when not under pressure; a second slide groove 421 is opened on the support plate 420, and the second slide groove 421 extends radially along the mounting shaft 310; at least two second support assemblies are installed on each mounting shaft 310, and a second adjustment mechanism is connected between two adjacent second support assemblies on the same mounting shaft 310, and the second adjustment mechanism is used to switch the upper second support assembly to an expanded state when the lower second support assembly moves downward, and the second adjustment mechanism includes a plurality of second adjustment units, and the plurality of second adjustment units are evenly distributed along the circumference of the mounting shaft 310; the structure of the second adjustment unit is consistent with the first adjustment unit 510, but the lower end of the first rack 511 in the second adjustment unit is slidably installed in the second slide groove 421 on the support plate 420 below it.

[0053] After the mounting base 200 and the multiple mounting racks 300 mounted thereon are taken out from the disinfection chamber 110, the medical device 700 is sleeved on the mounting shaft 310 from the upper end of the mounting shaft 310, and the medical device 700 moves downward under the action of gravity; when the medical device 700 contacts the support tray 410, under the action of gravity, pressure is applied to the support tray 410, driving the support tray 410 to move downward synchronously, and when the support tray 410 moves downward, the first rack 511 is driven to move downward synchronously, and the first rack 511 slides downward in the first slide groove 312, and the first rack 511 slides downward to drive the first gear 516 to rotate, and when the first gear 516 rotates, it drives the transmission shaft 512 and the second gear 517 to rotate synchronously, and the rotation of the second gear 517 drives the second rack 513 to move outward along the radial direction of the mounting shaft 310, thereby driving the connecting rod 514 and the support plate 420 to move outward synchronously, extending out of the receiving groove 311, and can be used to support the medical device 700. When the supporting plate 420 moves outward, the first rack 511 above it slides in the second sliding groove 421;

[0054] At this time, the second medical device 700 can be placed on the mounting shaft 310 from above the mounting shaft 310; when the supporting plate 420 located below is under pressure, the slider 422 moves downward relative to the connecting rod 514, driving the second (hereinafter referred to as the second) first rack 511 from bottom to top to move downward synchronously, and the second first gear 516 rotates, thereby driving the second transmission shaft 512 and the second second gear 517 to rotate synchronously, and then driving the second second rack 513 to move outward along the radial direction of the mounting shaft 310, and finally driving the second connecting rod 514 and the supporting plate 420 to move outward synchronously. After the supporting plate 420 extends out of the accommodating groove 311, it can support the third medical device 700 on the mounting shaft 310. Through this design, multiple medical devices 700 can be installed on each mounting shaft 310, thereby further improving the disinfection efficiency.

[0055] In a further embodiment, Figure 8 , Fig. 9 As shown, the first supporting component is a first spring, which is located in the annular groove 313, with the upper end of the first spring fixedly connected to the supporting plate 410, and the lower end fixedly connected to the annular groove 313; a vertical groove 515 is provided on the connecting rod 514, and the supporting plate 420 can be installed in the vertical groove 515 so as to move up and down; the second supporting component is a second spring, which is located in the vertical groove 515, and the upper and lower ends of the second spring are respectively connected to the supporting plate 420 and the connecting rod 514.

[0056] In the natural state, the first spring and the second spring respectively keep the preset distance between the tray 410 and the mounting base 200 and between the supporting plate 420 and the mounting base 200. When the tray 410 is subjected to the pressure of the medical device 700, the gravity of the medical device 700 gradually overcomes the elastic force of the first spring, thereby driving the tray 410 to move downward and approach the mounting base 200; when the supporting plate 420 is subjected to the pressure of the medical device 700, the gravity of the medical device 700 gradually overcomes the elastic force of the second spring, thereby driving the supporting plate 420 to move downward and approach the mounting base 200. After the disinfection is completed, the tray 410 and the supporting plate 420 are no longer subjected to the pressure of the medical device 700. Under the elastic force of the first spring and the second spring, the tray 410 and the supporting plate 420 are respectively away from the mounting base 200 and restored to the initial state, that is, the supporting plate 420 is located in the receiving groove 311 and does not block the axial movement of the medical device 700 on the mounting shaft 310.

[0057] Alternatively, the first supporting assembly and the second supporting assembly each include two magnets, the two magnets of the first supporting assembly are respectively installed below the annular groove 313 and below the supporting tray 410, and the magnetic poles of the two magnets facing each other are the same; the two magnets of the second supporting assembly are respectively installed at the lower end of the vertical groove 515 and the lower end of the slider 422, and the magnetic poles of the two magnets facing each other are the same.

[0058] In the natural state, the magnets keep the preset distance between the tray 410 and the mounting base 200 and between the supporting plate 420 and the mounting base 200. When the tray 410 is subjected to the pressure of the medical device 700, the gravity of the medical device 700 gradually overcomes the repulsion between the two magnets, thereby driving the tray 410 to move downward and approach the mounting base 200; when the supporting plate 420 is subjected to the pressure of the medical device 700, the gravity of the medical device 700 gradually overcomes the repulsion between the two magnets, thereby driving the supporting plate 420 to move downward and approach the mounting base 200. After the disinfection is completed, the tray 410 and the supporting plate 420 are no longer subjected to the pressure of the medical device 700. Under the repulsion of the magnets, the tray 410 and the supporting plate 420 are away from the mounting base 200 and return to the initial state, that is, the supporting plate 420 is located in the receiving groove 311 and does not block the axial movement of the medical device 700 on the mounting shaft 310.

[0059] In a further embodiment, Figure 3 , Figure 4 , Figure 5 As shown, a bracket 610 is rotatably provided in the disinfection chamber 110, and a connecting piece 620 is fixedly connected to the bottom of the bracket 610; the lower end surface of the connecting piece 620 abuts against the bottom wall of the disinfection barrel 100; a driving block 130 is fixedly connected to the middle of the connecting piece 620, and a docking magnetic block 201 is fixedly connected to the lower part of the mounting base 200, and a mounting groove 131 is provided on the driving block 130, and the docking magnetic block 201 is magnetically mounted in the mounting groove 131, and the driving block 130 is connected to the driving member; a spiral stirring blade 600 is installed on the bracket 610;

[0060] The supporting mechanism 400 installed on the mounting frame 300 is arranged in a spiral shape in the vertical direction as a whole, and its rotation direction and pitch are consistent with the rotation direction and pitch of the stirring blade 600; the upper end of the stirring blade 600 is higher than the highest second supporting component, and the lower end of the stirring blade 600 is lower than the lowest first supporting component. The vertical distance between the supporting tray 410 and the stirring blade 600 above it, the vertical distance between the supporting tray 410 and the stirring blade 600 below it, the vertical distance between the supporting plate 420 and the top of it, and the vertical distance between the supporting plate 420 and the stirring blade 600 below it are all equal.

[0061] When the medical device 700 needs to be disinfected, the docking magnetic block 201 is separated from the mounting groove 131, and the mounting base 200 and the multiple mounting frames 300 installed thereon are rotated clockwise and taken out from the disinfection chamber 110. After the multiple medical devices 700 are sequentially connected to the mounting shaft 310 from top to bottom, the installation of the medical device 700 is completed. Thereafter, the mounting base 200 and the multiple mounting frames 300 installed thereon are rotated counterclockwise until the motor 210 is inserted into the mounting groove 131. Thereafter, the cover 120 is closed and the motor 210 is started. The motor 210 drives the mounting base 200 to rotate reciprocatingly. At the same time, the motor 210 drives the stirring blade 600 to rotate synchronously. Since the first supporting assembly and the second supporting assembly are arranged in a spiral in the vertical direction, that is, any two medical devices 700 are not on the same horizontal plane, during the disinfection process, there is no situation where one medical device 700 blocks the disinfectant from flowing to the adjacent medical device 700. Furthermore, by providing a spiral stirring blade 600, multiple medical devices 700 in the same vertical position will not block the flow of disinfectant. During the entire rotation process, the disinfectant is in a spiral state as a whole and constantly changes the spiral direction, thereby enhancing the disinfection effect on the medical devices 700. By making the rotation direction and pitch of the spiral arrangement of the first supporting component and the second supporting component in the vertical direction consistent with the rotation direction and pitch of the stirring blade 600, the vertical distance between the supporting tray 410 and the stirring blade 600 above it, the vertical distance between the supporting tray 410 and the stirring blade 600 below it, the vertical distance between the supporting plate 420 and the top of it, and the vertical distance between the supporting plate 420 and the stirring blade 600 below it are all equal, so that the upper and lower sides of the medical device 700 are washed by water, further optimizing the disinfection effect.

[0062] After the disinfection work is completed, the base 200 is installed again and separated from the driving part, and then the mounting base 200 and the mounting frame 300 and the medical device 700 thereon are rotated clockwise to take out the disinfection chamber 110. After taking them out, the mounting base 200 and the mounting frame 300 are turned upside down, and the medical device 700 moves away from the mounting base 200 under the action of gravity. At this time, the supporting tray 410 and the supporting plate 420 are no longer subjected to the pressure of the medical device 700, and the medical device 700 naturally slides off the mounting shaft 310, completing the disassembly of the medical device 700 after disinfection.

[0063] In a further embodiment, Figure 4 , Figure 5 , Figure 6As shown, a mounting frame 300 includes two adjacent mounting shafts 310, and two first supporting components on the two mounting shafts 310 in the same mounting frame 300 are located at the same horizontal plane, and two second supporting components are located at the same horizontal plane. It can be used to sterilize complex medical devices 700 with joints or grooves, such as scissors, vascular clamps, needle holders, bone clamps, etc.

[0064] In a further embodiment, Figure 3 , Figure 4 , Figure 5 As shown, a connecting ring 630 is installed on the upper part of the bracket 610 so as to be movable up and down; the upper end of the stirring blade 600 is fixedly connected to the connecting ring 630, and the stirring blade 600 can be elastically deformed. When the motor 210 drives the stirring blade 600 to rotate clockwise, the disinfectant flows downward along the upper surface of the stirring blade 600, and the stirring blade 600 is subjected to the reaction force of the water, and the connecting ring 630 moves upward, the pitch of the stirring blade 600 increases, the distance between the medical device 700 and the stirring blade 600 above it increases, and the distance between the medical device 700 and the stirring blade 600 below it decreases, thereby causing a flow rate difference between the upper and lower water flows of the medical device 700, and then forming a downward water flow between the two layers of stirring blades 600, so as to rinse the medical device 700 from top to bottom. When the motor 210 drives the stirring blade 600 to rotate counterclockwise, the disinfectant flows downward along the upper surface of the stirring blade 600, and the stirring blade 600 is subjected to the reaction force of the water above, the connecting ring 630 moves downward, the pitch of the stirring blade 600 decreases, the distance between the medical device 700 and the stirring blade 600 above it decreases, and the distance between the medical device 700 and the stirring blade 600 below it increases, which leads to a flow rate difference between the upper and lower water flows of the medical device 700, and then an upward water flow is formed between the two layers of stirring blades 600, so as to flush the medical device 700 from bottom to top. During the entire disinfection process, the stirring blade 600 driven by the motor 210 reciprocates, thereby continuously switching the direction of the water flow for flushing the medical device 700, and further optimizing the disinfection effect.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
