Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an ultraviolet disinfection device. Background Art

[0002] The hematology department is a branch of internal medicine, mainly treating problems of the hematopoietic system, providing professional services for many non-hematological hematological problems and conducting a number of technical tests. Common red blood cell diseases include anemia, iron deficiency anemia, aplastic anemia, and abnormal hemoglobin.

[0003] In the hematology department, the collected samples and medical devices need to be placed in an ultraviolet disinfection cabinet for storage, and the blood storage equipment needs to be cleaned and disinfected regularly to ensure the safe storage and use of blood. The existing Chinese patent publication: CN213608474U discloses an ultraviolet disinfection device for medical laboratories. Through the settings of a driving motor, an upper fixing plate and a lower fixing plate, the driving motor drives the round rod and the lower fixing plate to rotate, the round rod drives the upper fixing plate to rotate, thereby driving the test tubes and experimental utensils to rotate. The surfaces of the test tubes and experimental utensils can be evenly irradiated by ultraviolet rays for disinfection, avoiding insufficient disinfection caused by irradiation dead angles. However, before the test tubes are stored and disinfected, the test tubes need to be cleaned. After the test tubes are inverted, the water on the inner wall of the test tubes will drip downward. If not cleaned in time, it is easy to cause more accumulated water inside the equipment. Summary of the Invention

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 8 , an ultraviolet disinfection device shown in the figure, including a device housing 1 and a top cover 2 installed on the top of the device housing 1. A positioning disk 3 is fixedly installed inside the device housing 1. A plurality of centrally symmetric suspension holes are formed on the surface of the positioning disk 3. A test tube body 4 is arranged inside the suspension holes. An ultraviolet light bar 5 is arranged inside the test tube body 4. A power supply 6 is fixedly installed between the bottom end of the ultraviolet light bar 5 and the device housing 1 to perform ultraviolet light disinfection on the test tube body 4 from the inside out; further including: a tube cleaning mechanism for cleaning the water stains inside the test tube body 4, and the tube cleaning mechanism is installed inside the device housing 1; a drainage mechanism for draining the water cleaned inside the test tube body 4, and the drainage mechanism is installed below the test tube body 4; a tube positioning mechanism for positioning and installing the test tube body 4, and the tube positioning mechanism is installed at the bottom of the positioning disk 3.

[0031] The pigging mechanism includes an electric telescopic rod 8 fixedly installed at the bottom of the positioning disk 3. The output end at the bottom of the electric telescopic rod 8 is fixedly installed with a pulling block 9. The electric telescopic rod 8 can adjust the vertical position of the pulling block 9. A sleeve 10 is slidably installed on the outer side of the ultraviolet light rod 5. A sponge brush 11 is fixedly installed on the outer side of the sleeve 10 for cleaning the water stains inside the test tube body 4. A sliding tube 12 is fixedly installed at the bottom of the sleeve 10. The bottom end of the sliding tube 12 is rotatably installed with a connecting rod 13. One end of the connecting rod 13 is fixedly connected to the pulling block 9, enabling the pulling block 9 to achieve the vertical movement of the sliding tube 12 through the connecting rod 13. An installation disk 14 is fixedly installed inside the device housing 1 and is located below the test tube body 4. Both the electric telescopic rod 8 and the sliding tube 12 penetrate through the installation disk 14. A collar 15 is fixedly installed at the bottom of the installation disk 14 on the outer side of the sliding tube 12. Two helical strips 16 distributed symmetrically about the center are fixedly installed inside the collar 15. A helical groove matching with the helical strips 16 is opened on the outer side of the sliding tube 12, enabling the sliding tube 12 to move along the outer side of the helical strips 16 through the helical groove when moving, realizing the self-rotation of the cleaning sponge brush 11;

[0032] When the electric telescopic rod 8 operates, it can push the connecting rod 13 to move upward through the pulling block 9, causing the connecting rod 13 to push the sliding tube 12 to move upward along the outer side of the ultraviolet light rod 5. The helical groove on the sliding tube 12 moves along the helical strips 16 on the collar 15, causing the sliding tube 12 to rotate. The sliding tube 12 drives the sponge brush 11 to rotate and move upward along the inner side of the test tube body 4 through the sleeve 10 to clean the water stains inside the test tube body 4, and the sponge brush 11 is reset downward through the electric telescopic rod 8, facilitating the disinfection of the cleaned test tube body 4 by the ultraviolet light rod 5, thereby achieving the effect of comprehensive disinfection and water stain cleaning.

[0033] The drainage mechanism includes a plurality of mounting cylinders 17 fixedly installed on the top of the mounting plate 14 in central symmetry. The number of the mounting cylinders 17 is the same as that of the test tube bodies 4. The plurality of mounting cylinders 17 are respectively located directly below the plurality of test tube bodies 4. A water filtering cylinder 18 is fixedly installed inside the mounting cylinder 17. The water filtering cylinder 18 is located outside the sliding tube 12. The inner diameter of the water filtering cylinder 18 is smaller than the outer diameter of the sponge brush 11, which is convenient for extruding the sponge brush 11. A water filtering hopper 19 is fixedly installed on the top of the water filtering cylinder 18, which is convenient for putting the sponge brush 11 into the water filtering cylinder 18. The filter holes on the surfaces of the water filtering cylinder 18 and the water filtering hopper 19 are both inclined plane structures, which is convenient for discharging the water in the sponge brush 11. A plurality of drain pipes 20 in central symmetry are fixedly installed at the bottom of the mounting cylinder 17. The drain pipes 20 penetrate through the mounting plate 14, which is convenient for discharging the water extruded by the sponge brush 11 to the bottom of the device housing 1. Two symmetrically distributed support rods 36 are fixedly installed inside the mounting cylinder 17. The support rods 36 are located directly below the test tube body 4 and above the water filtering hopper 19 to provide support for the bottom end of the test tube body 4. A sliding ring 7 is fixedly installed at the bottom of the mounting cylinder 17. A rubber block 21 matching the spiral groove on the sliding tube 12 is fixedly installed inside the sliding ring 7 to provide sealing for the sliding ring 7;

[0034] When the sponge brush 11 moves downward and the bottom of the sponge brush 11 contacts the inside of the water filtering hopper 19, the sponge brush 11 is extruded by using the inclined plane of the water filtering hopper 19, so that the sponge brush 11 enters the water filtering cylinder 18. Through the inclined filter holes on the water filtering hopper 19 and the water filtering cylinder 18, the water in the sponge brush 11 is discharged into the mounting cylinder 17 and then discharged from the drain pipe 20 to the bottom of the device housing 1. The electric telescopic rod 8 can drive the sponge brush 11 to move upward again to clean the test tube body 4 again, improving the cleaning efficiency of the test tube body 4, thus achieving the effect of automatic drainage and facilitating repeated cleaning.

[0035] The fixed tube mechanism includes a plurality of positioning cylinders 22 that are fixedly installed at the bottom of the positioning disk 3 in central symmetry. The number of the positioning cylinders 22 is the same as the number of the test tube bodies 4. The test tube bodies 4 are located inside the positioning cylinders 22. Two symmetrically distributed pull plates 24 are arranged on the outer sides of the positioning cylinders 22. Two vertically distributed pressure wheels 25 are arranged on the side of the pull plate 24 close to the positioning cylinder 22 for pressing and positioning the test tube bodies 4. An opening for the limit sliding of the pressure wheels 25 is formed on the outer side of the positioning cylinder 22. The outer sides of the pressure wheels 25 are arc-shaped concave surfaces and are in contact with the outer sides of the test tube bodies 4, facilitating the clamping of the outer sides of the test tube bodies 4. Positioning plates 26 are rotatably installed at both ends of the pressure wheels 25. The positioning plates 26 are fixedly installed on the outer sides of the pull plates 24. Ratchets 27 located inside the positioning plates 26 are fixedly installed at both ends of the pressure wheels 25. Inside the positioning plates 26 of the test tube bodies 4, teeth 28 that cooperate with the ratchets 27 are rotatably installed, enabling the pressure wheels 25 to provide limits for the test tube bodies 4 when the test tube bodies 4 are pulled upward. Two symmetrically distributed springs 29 are fixedly installed between the pull plates 24 and the positioning cylinders 22, facilitating the elastic clamping of the outer sides of the test tube bodies 4 by the pressure wheels 25;

[0036] The user inserts the test tube body 4 upside down into the suspension hole of the top cover 2, enabling the outer side of the test tube body 4 to move along between the four pressure wheels 25. The friction between the test tube body 4 and the pressure wheels 25 can drive the pressure wheels 25 to rotate downward, causing the pressure wheels 25 to drive the ratchets 27 to move along the teeth 28. When the test tube body 4 comes into contact with the support rod 36 on the mounting cylinder 17, by utilizing the elasticity of the spring 29, the pull plate 24 drives the pressure wheels 25 through the positioning plates 26 to clamp and position the outer side of the test tube body 4, completing the placement of the test tube body 4. When the sponge brush 11 moves upward along the inner side of the test tube body 4, it can utilize the limit of the teeth 28 on the ratchet 27, enabling the pressure wheels 25 to only rotate in one direction. Thus, the pressure wheels 25 can provide limits for the upward movement of the test tube body 4, improving the smoothness of the upward cleaning of the test tube body 4 by the sponge brush 11. When removing the tube, the user pulls the two pull plates 24 away from the positioning cylinder 22, causing the pressure wheels 25 to move away from the test tube body 4, and then the test tube body 4 can be taken out, thereby achieving the effects of positioning and clamping and smooth cleaning, and improving the smoothness of the storage of the test tube body 4.

[0037] Working principle: First, the user opens the top cover 2 and inserts the test tube body 4 upside down into the suspension hole of the top cover 2, so that the outside of the test tube body 4 moves along between the four pressure wheels 25. The friction between the test tube body 4 and the pressure wheels 25 can drive the pressure wheels 25 to rotate downward, causing the pressure wheels 25 to drive the ratchet wheel 27 to move along the teeth 28, so that the bottom end of the test tube body 4 contacts the support rod 36 on the mounting cylinder 17. The support rod 36 provides support for the bottom of the test tube body 4. At this time, using the elasticity of the spring 29, the pull plate 24 drives the pressure wheels 25 to contact the outside of the test tube body 4 through the positioning plate 26, and elastically clamp the outside of the test tube body 4. Then, the user starts the electric telescopic rod 8. The electric telescopic rod 8 pushes the connecting rod 13 upward through the pull block 9, causing the connecting rod 13 to push the sliding tube 12 to move upward along the outside of the ultraviolet light rod 5. The spiral groove on the sliding tube 12 moves along the spiral strip 16 on the collar 15, causing the sliding tube 12 to rotate. The sliding tube 12 drives the sponge brush 11 to rotate and move upward along the inside of the test tube body 4 through the sleeve 10, cleaning the water stains in the test tube body 4. And using the limit of the teeth 28 on the ratchet wheel 27, the pressure wheels 25 can only rotate in one direction, providing a limit for the upward movement of the test tube body 4 and improving the smoothness of the sponge brush 11 for upward cleaning of the test tube body 4. At this time, the electric telescopic rod 8 pulls the connecting rod 13 downward through the pull block 9, causing the sponge brush 11 to reset downward and perform secondary cleaning on the inside of the test tube body 4. When the bottom of the sponge brush 11 contacts the inside of the water filtering hopper 19, using the inclined surface inside the water filtering hopper 19, the sponge brush 11 is squeezed, causing the sponge brush 11 to enter the water filtering cylinder 18. Through the inclined filter holes on the water filtering hopper 19 and the water filtering cylinder 18, the water in the sponge brush 11 is drained into the mounting cylinder 17 and discharged from the drain pipe 20 to the bottom of the device housing 1. Finally, the user seals the top of the device housing 1 through the top cover 2 and turns on the power supply 6 to supply power to the ultraviolet light rod 5, so that the ultraviolet light rod 5 disinfects the test tube body 4 from the inside out, thus achieving the effect of comprehensive disinfection and cleaning of water stains, and facilitating the storage of the test tube body 4.

[0038] Embodiment 2: Please refer to Figures 1 - 4 , this embodiment further explains Embodiment 1. A reflective layer 30 is fixedly installed inside the device housing 1 in the figure to improve the irradiation effect of the ultraviolet light rod 5. A baffle plate 31 is fixedly installed between the top of the power supply 6 and the inside of the device housing 1. The ultraviolet light rod 5 penetrates through the baffle plate 31. A drain plug 32 is fixedly installed on the outside of the device housing 1 above the baffle plate 31 to facilitate draining the water in the device housing 1. A waterproof sleeve 33 is fixedly installed between the outside of the ultraviolet light rod 5 and the baffle plate 31 to prevent the water on the baffle plate 31 from seeping into the power supply 6.

[0039] In this embodiment: When the ultraviolet light rod 5 operates, the reflective layer 30 inside the device housing 1 can be utilized to increase the irradiation surface of the ultraviolet light rod 5, improve the irradiation efficiency of the ultraviolet light rod 5, facilitate the rapid disinfection of the test tube body 4. The baffle plate 31 can catch the water cleaned out of the test tube body 4, and the waterproof sleeve 33 on the ultraviolet light rod 5 can provide the sealing performance at the connection between the ultraviolet light rod 5 and the baffle plate 31, protecting the power supply 6 below the baffle plate 31. During later cleaning, the user can open the drain plug 32 to drain the water on the baffle plate 31, facilitating timely cleaning.

[0040] Embodiment 3: Please refer to Figures 6 - 8 , this embodiment further illustrates other embodiments. A rubber sleeve pad 23 is fixedly installed on the outer side of the support rod 36 in the figure. The outer side of the rubber sleeve pad 23 is in contact with the bottom end of the test tube body 4, facilitating the support for the bottom end of the test tube body 4. A guide rod 34 is arranged inside the spring 29. One end of the guide rod 34 is fixedly installed on the outer side of the positioning cylinder 22. A perforation for the positioning cylinder 22 to slide through is formed on the outer side of the pull plate 24, improving the smoothness of the movement of the pull plate 24. An arc-shaped pull bar 35 is fixedly installed on the side of the pull plate 24 away from the positioning plate 26, facilitating the pulling of the two pull plates 24 apart.

[0041] In this embodiment: The support rod 36 can be in contact with the bottom end of the test tube body 4 through the rubber sleeve pad 23. Utilizing the elasticity of the rubber sleeve pad 23, it can prevent the test tube body 4 from being bumped during transportation, improving the safety of the storage of the test tube body 4. The user can pull the pull plate 24 to move through the arc-shaped pull bar 35 on the pull plate 24, facilitating the synchronous opening of the two pull plates 24 away from each other, and the pull plate 24 can move along the outer side of the guide rod 34, improving the smoothness of the movement of the pull plate 24.
