Description

Technical Field

[0001] The present invention belongs to the technical field of medical device storage, and in particular, relates to a low-temperature storage device for medical devices. Background Art

[0002] Surgical instruments refer to the medical instruments used in clinical surgery. Surgical instruments refer to the medical instruments used in clinical surgery. These medical instruments often require proper maintenance before and after use to increase the service life of the medical instruments. Most medical instruments need to be disinfected and sterilized before and after use.

[0003] The existing patent application number is CN202210737711.1, which is a medical device safe low-temperature storage device, including a bottom block, a mounting shell, an opening and closing mechanism, a pushing mechanism, and a storage rack, etc.; the mounting shell has two layers, the lower and upper layers, two bottom blocks are provided on the left and right sides of the lower part of the mounting shell, there are four bottom blocks, the front side of the mounting shell is provided with an opening and closing mechanism, a pushing mechanism is provided between the opening and closing mechanism and the mounting shell, a storage rack is provided on the pushing mechanism, the storage rack is slidably connected to the mounting shell, and there are four layers in the storage rack. The present invention senses that the distance between the storage rack and the preset value through the second distance sensor, so that the first fan group and the condenser are started, so that the first fan group blows cold air to the medical device, achieving the effect of cooling and preservation.

[0004] The above patent is to place the medical devices that need to be stored at low temperatures on a storage rack, and perform ultraviolet disinfection through ultraviolet lamps and disinfection with disinfectant by disinfection mechanisms. However, there are a lot of blind spots in this disinfection method. For example, the back of the medical device in contact with the storage rack cannot be irradiated by ultraviolet light, and it is also difficult to be sprayed and disinfected by the disinfection mechanism. If the front is disinfected, the device is opened, the storage rack is slid, and it is manually turned over, but this requires the medical device to contact the outside world again, resulting in a decrease in the disinfection effect. If it is not turned over manually, it will also affect the sterilization effect. When it is subsequently stored at low temperatures, a large number of bacteria will be carried along and stored together. Although bacteria are difficult to grow at low temperatures, a large number of bacteria may go dormant in a low-temperature environment. When the medical device is taken out for medical surgery, the bacteria will reawaken, causing bacterial infection in the patient and affecting life and health.

[0043] like Figure 5 and Figure 6 As shown, a rotating gear 15 is fixedly installed at the rear end of the second rotating plate 9, a fixed gear ring 16 is fixedly installed in the cover 2, the rotating gear 15 meshes with the fixed gear ring 16, a driving column 17 and a driving gear 19 are rotatably installed in the cover 2, the driving column 17 is fixedly connected to the first rotating plate 8, a driving gear ring 18 is fixedly installed on the driving column 17, the driving gear ring 18 meshes with the driving gear 19, and the driving gear 19 is fixedly connected to the driving end of the rotating motor 3.

[0044] like Figure 7 As shown, a connecting groove 111 is provided in the first fixed rod 11, a spray hole 131 is provided on the spray clamp 13, and the spray hole 131 is connected to the connecting groove 111. A first connecting pipe 20 is fixedly installed on the rotating gear 15, and the first connecting pipe 20 passes through the rotating gear 15 and the second rotating plate 9 and is connected to the connecting groove 111. A second connecting pipe 21 is fixedly installed and connected to the driving column 17, and the second connecting pipe 21 is rotatably connected and connected to the first connecting pipe 20. The driving column 17 is rotatably connected and connected to the infusion pipe 401 and the air pipe 501. When the air pump 5 needs to deliver cold air or the liquid pump 4 needs to deliver disinfectant, it is delivered to the driving gear ring 18 through the air pipe 501 or the infusion pipe 401, and then transmitted to the three second connecting pipes 21, and then delivered to the first connecting pipe 20, and the cold air or disinfectant is sprayed from the spray hole 131 through the connecting groove 111 to spray and clean or cool the medical device.

[0045] like Figure 7 As shown, a sliding clamp block 132 is slidably mounted on the spray clamp block 13, and a first spring 133 is fixedly mounted on the bottom end of the sliding clamp block 132. The other end of the first spring 133 is fixedly connected to the spray clamp block 13. When the upper and lower spray clamp blocks 13 are used to clamp the top and bottom ends of the medical device, the two first springs 133 are compressed, and the vertices of the two sliding clamp blocks 132 and the center of gravity of the medical device are located in a straight line. The medical device held against by the two sliding clamp blocks 132 is fixed by the elastic force of the two compressed first springs 133.

[0046] When no medical device is clamped, the gravity of the first spring 133 is insufficient to compress or stretch the first spring 133 , and the upper and lower first springs 133 maintain their original lengths;

[0047] The distance between the vertices of the two first springs 133 is relatively small, much smaller than the length of the medical device. When the medical device is clamped and vertically, the two first springs 133 are in a compressed state, regardless of whether the first spring 133 is at the highest point or the lowest point. When the first spring 133 is at the lowest point, the first spring 133 reaches the compression limit, and when the first spring 133 is at the highest point, the first spring 133 is still in a compressed state.

[0048] A first limiting groove 134 is provided on the sliding clamp 132, and a first limiting slider 135 matching the first limiting groove 134 is provided in the spray clamp 13 to limit the sliding of the sliding clamp 132 to prevent the sliding clamp 132 and the medical device from being rotated and tilted, causing the sliding clamp 132 to tilt, resulting in the vertices of the two sliding clamps 132 and the center of gravity of the medical device no longer being in a straight line.

[0049] like Figure 8 , Fig. 9 and Fig.11 As shown, the limit clamping frame 14 includes a fixed bracket 141, a connecting sleeve 143 and a sliding arc block 145. The second fixed rod 12 is provided with a mounting groove 121 matching the sliding arc block 145. The fixed bracket 141 is slidably installed with a limit clamping block 147. The side end of the fixed bracket 141 is fixedly installed with a connecting shaft rod 142. The connecting shaft rod 142 is slidably connected to the connecting sleeve 143. The connecting sleeve 143 is slidably connected to the sliding arc block 145. The limit clamping frame 14 is firstly The side end clamping of block 147 installs the medical device on the limit clamping frame 14, and the transverse limit clamping frame 14 is slidably installed on the second fixed rod 12 through the installation slide groove 121, and then slid to the spray clamping block 13, and then the fixed bracket 141 and the connecting sleeve 143 are rotated to make the limit clamping frame 14 and the medical device vertical, press and release the sliding clamping block 132 to complete the longitudinal fixation of the head and tail of the medical device, and then slide the limit clamping block 147 to release the transverse side clamping of the medical device.

[0050] The second fixed rod 12 is evenly provided with a plurality of arc-shaped mounting slots 122, which match the positions of the spray clamping block 13, and the arc-shaped mounting slots 122 and the spray clamping block 13 are located in the same plane, and a limiting arc block 144 matching the arc-shaped mounting slots 122 is fixedly installed on the connecting sleeve 143, and an arc-shaped protrusion matching the inner arc surface of the limiting arc block 144 is provided on the sliding arc block 145. Fig.12 and Fig.13As shown, when the limit clamping frame 14 is slid, the limit arc block 144 abuts against the arc-shaped protrusion on the sliding arc block 145. When the limit clamping frame 14 is rotated, the connecting sleeve 143 is first slid to make the limit arc block 144 slide out of the installation slot 121, and then the connecting sleeve 143 is rotated to drive the connecting shaft 142 and the fixed bracket 141 to rotate, and then the connecting sleeve 143 is clamped into the arc-shaped installation slot 122, so that the limit clamping frame 14 is fixed and can no longer rotate or slide.

[0051] The connecting shaft 142 is a regular hexagonal column, and a regular hexagonal groove matching the connecting shaft 142 is provided in the connecting sleeve 143. The connecting sleeve 143 is first slid, and then the connecting sleeve 143 is rotated to control the rotation of the connecting shaft 142 and the fixed bracket 141. The regular hexagonal column can slide the connecting shaft 143 out of the sliding arc block 145 without affecting the connecting shaft 142 and the fixed bracket 141. When the connecting sleeve 143 is rotated, the connecting shaft 142 and the fixed bracket 141 can be driven to rotate.

[0052] A second spring 146 is fixedly mounted on the connecting shaft 142 , and the other end of the second spring 146 is fixedly connected to the connecting sleeve 143 . When the limiting arc block 144 is stuck in the arc-shaped mounting groove 122 , the second spring 146 is in a stretched state, so that the limiting arc block 144 can be tightly stuck in the arc-shaped mounting groove 122 .

[0053] An adjusting bolt 148 is rotatably installed on the limit clamping block 147, and the adjusting bolt 148 is threadedly connected to the fixed bracket 141. A second limit sliding block 149 is fixedly installed on the side end of the limit clamping block 147, and a second limit sliding groove 1410 matching the second limit sliding block 149 is provided on the fixed bracket 141. The sliding of the limit clamping block 147 is controlled by rotating the adjusting bolt 148, and the second limit sliding groove 1410 is used for limiting to prevent the limit clamping block 147 from rotating with the adjusting bolt 148. The medical device is clamped by adjusting the distance between the two limit clamping blocks 147. When the limit clamping frame 14 and the medical device have been rotated vertically upward, and the sliding clamping block 132 completes the longitudinal clamping of the head and tail of the medical device, the limit clamping block 147 is rotated again to release the lateral clamping of the side end of the medical device.

[0054] like Fig. 9 and Fig.10As shown, two (1411) are provided on the limit clamping block 147, (1412) is rotatably installed in (1411), and (1413) is fixedly installed on (1412). When the adjusting bolt 148 is rotated to adjust the distance between the two limit clamping blocks 147, (1413) can be tightly abutted against the medical device, so that (1413) is deformed, and the medical device is clamped and fixed by (1413). When the sliding clamping block 132 completes the clamping and fixing of the medical device up and down, the adjusting bolt 148 is rotated to loosen the lateral clamping of (1413) on the adjusting bolt 148, and (1413) returns to its original shape, but (1413) is still slightly abutted against the adjusting bolt 148. Two (1413) form a group, and there are two groups of (1413) for the medical device. The medical device is limited to prevent displacement during rotation and sliding, so that the center of gravity of the medical device is no longer in a straight line with the apex of the two sliding clamps 132. When the medical device slides relative to the limit clamping frame 14, the sliding medical device will slide relative to (1413), or drive (1413) and (1412) to rotate, which will not affect the sliding of the medical device. At the same time, the distance between the two groups (1413) and the limit clamping block 147 is short, which is smaller than the sliding distance of the medical device. The part of the medical device located between the two groups (1413) will continue to slide to the top or bottom of the area between the two groups (1413), so it will not affect the illumination of the ultraviolet disinfection lamp 7, nor will it affect the liquid spray disinfection and jet cooling of the spray hole 131.

[0055] A positioning rod 201 is fixedly mounted on the cover 2, and a positioning slot matching the positioning rod 201 is provided on the housing 1. The cover 2 is positioned and installed by the positioning rod 201 to prevent the cover 2 from rotating and deviating when the first rotating plate 8 rotates subsequently.

[0056] The present invention slides out the cover 2, pulls the limiting arc block 144 outward, and then rotates the connecting sleeve 143 to make the limiting arc block 144 tightly attached to the arc protrusion of the sliding arc block 145, slides the limiting clamping frame 14 from the second fixing rod 12 along the installation slide groove 121, inserts the medical device between the two limiting clamping blocks 147, rotates the adjusting bolt 148, adjusts the distance between the limiting clamping blocks 147, and clamps and fixes the side end of the medical device.

[0057] Then, along the installation slide groove 121, the limit clamping frame 14 that clamps and fixes the medical device is slidably installed on the second fixed rod 12. When the sliding arc block 145 slides to the arc-shaped installation groove 122, it stops sliding, pulls the limit arc block 144, and makes the limit arc block 144 disengage from the arc-shaped installation groove 122. Then, the connecting sleeve 143 is rotated and the limit arc block 144 is released, and the limit arc block 144 is clamped into the arc-shaped installation groove 122. At this time, the clamped and fixed medical device is also vertically upward. Press the sliding clamp block 132 and then release it to clamp and fix the upper and lower ends of the medical device. Turn the adjusting bolt 148 to loosen the clamping of the limit clamping block 147 on the medical device, so that the sliding clamp block 132 and the medical device will not be affected by the limit clamping block 147 when sliding back and forth.

[0058] After all the medical devices are placed and clamped, the cover 2 is closed by sliding cover, and the ultraviolet disinfection lamp 7 and the rotating motor 3 are started. The ultraviolet disinfection lamp 7 performs ultraviolet disinfection on the medical devices in the housing 1. The rotating motor 3 drives the driving gear 19 to rotate, so that the driving gear ring 18 and the driving column 17 rotate, thereby driving the second connecting pipe 21 and the first rotating plate 8 to revolve in the cover 2. The first rotating plate 8 also drives the second rotating plate 9 and the rotating gear 15 to revolve, but the rotating gear 15 is meshed with the fixed gear ring 16. When the rotating gear 15 rotates, it will also rotate. The medical device clamped by the two sliding clamps 132 will slide continuously with the revolution and rotation. For example, when the head of the medical device is facing up and the tail is facing down, the sliding clamp 1 connected to the tail The vertex 32 is farthest from the limit clamping frame 14, and the vertex of the sliding clamp block 132 connected to the head is closest to the limit clamping frame 14. For example, when the medical device rotates to the point where the tail is facing up and the head is facing down, the vertex of the sliding clamp block 132 connected to the head is farthest from the limit clamping frame 14, and the vertex of the sliding clamp block 132 connected to the tail is closest to the limit clamping frame 14. The medical device and the two sliding clamp blocks 132 will slide back and forth. The areas of the medical device that were originally blocked by the fixed bracket 141 and could not be irradiated by the ultraviolet disinfection lamp 7 will be re-irradiated by the ultraviolet light of the ultraviolet disinfection lamp 7 during the triple movement of revolution, rotation and reciprocating sliding, eliminating blind spots in illumination and allowing the medical device to be fully disinfected by the ultraviolet disinfection lamp 7.

[0059] After the ultraviolet disinfection treatment is completed, turn off the ultraviolet disinfection lamp 7, start the liquid pump 4, and pass the disinfectant in the liquid storage tank 6 through the driving column 17, the second connecting pipe 21, the first connecting pipe 20 and the connecting groove 111, and finally spray out from the spray hole 131, and spray the disinfectant from both ends of the medical device, so that the medical device is sprayed without dead angles and in all directions, so as to achieve further disinfection and spraying. A solenoid valve is provided in the discharge pipe 101, and the solenoid valve can be closed to prevent the disinfectant from being discharged after spraying, so that the lower part of the shell 1 accumulates. When the medical device revolves to the lower part, it is immersed and rotated to clean by self-rotation and the accumulated disinfectant. After cleaning, the solenoid valve in the discharge pipe 101 is opened to discharge the disinfectant waste liquid.

[0060] After the disinfectant is sprayed, the liquid pump 4 is turned off and the air pump 5 is started. The air pump 5 is connected to the external cold air pipe. Both the liquid infusion pipe 401 and the air infusion pipe 501 are provided with a one-way valve. The air pump 5 delivers dry cold air, which passes through the driving column 17, the second connecting pipe 21, the first connecting pipe 20 and the connecting groove 111, and is finally sprayed from the spray hole 131 to the medical device. The sprayed cold air cools the medical device and sprays off the residual disinfectant on the medical device. A thermometer is also installed in the shell 1. When the temperature in the shell 1 reaches the preset temperature value, the output of the solenoid valve in the discharge pipe 101 is adjusted, and the input rate of the air pump 5 is adjusted to keep the temperature in the shell 1 within the preset temperature range, thereby realizing low-temperature storage of the medical device.

[0061] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present invention may make equivalent replacements or changes according to the technical solution and inventive concept of the present invention without departing from the scope of the technical solution of the present invention, and all of these shall be covered within the protection scope of the present invention.
