Description

Technical Field

[0001] The invention belongs to the technical field of medical testing equipment and relates to a waste sample processing device for clinical medical testing. Background Art

[0002] Medical testing is a means of medical diagnosis using modern physical and chemical methods and means. Medical testing plays a key role in disease diagnosis, disease monitoring, and treatment effect evaluation. In the process of medical testing, various samples usually need to be tested, and medical testing will produce a large amount of test waste liquid. The test waste liquid contains a large number of pathogens and needs to be treated. At present, most medical institutions adopt the method of direct discharge after simple dilution, or hand it over to a professional third party for treatment. However, these methods have obvious defects. Simple dilution is difficult to completely remove harmful substances in the waste liquid, which is easy to cause environmental pollution. At the same time, relying on third-party treatment is not only costly, but also has transportation and storage risks. In addition, if the waste liquid is not treated in time, it is easy to pollute the testing environment, thereby affecting the test results and causing a lot of waste of manpower and material resources.

[0003] In order to solve the above problems, the present invention proposes a waste sample processing device for clinical medical testing. Summary of the invention

[0004] In order to solve the problems existing in the background technology, the present invention proposes a waste sample processing device for clinical medical testing.

[0005] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present invention is as follows: a waste sample processing device for clinical medical testing includes a box body, an ultraviolet lamp is arranged on the inner wall of the box body; a threaded tube is arranged in the box body for up and down movement, and a threaded rod is connected to the threaded tube for up and down movement, and a piston cylinder is connected to the lower end of the threaded rod; a through hole is opened at the outward end of the piston cylinder, and a piston plate is elastically arranged in the piston cylinder; the ultraviolet lamp converts oxygen in the air in the box body into ozone, and when the piston cylinder moves downward, the ozone on the upper part of the box body is sucked, and then the piston cylinder moves downward to the waste liquid and injects ozone into the waste liquid, and then the piston cylinder sucks the waste liquid, and when the piston cylinder moves upward, the waste liquid is sprayed out.

[0006] Furthermore, a pull rope is fixedly connected between the piston plate and the threaded tube.

[0007] Furthermore, there are multiple piston cylinders, and the multiple piston cylinders are distributed along the circumference of the axis of the threaded tube.

[0008] Furthermore, a fixed tube is fixedly arranged on the top of the box body, the threaded tube is slidably arranged in the fixed tube with upper and lower limits, a first gear ring is rotatably arranged in the fixed tube, and the threaded tube and the first gear ring are threadedly connected; a first motor is arranged in the fixed tube, and the first motor is connected to a first gear meshing with the first gear ring.

[0009] Furthermore, the threaded rod is threadedly connected with a second gear ring, and the second gear ring is rotatably arranged in the threaded tube; a second motor is arranged in the threaded tube, and a second gear meshing with the second gear ring is fixedly mounted on the motor shaft of the second motor.

[0010] Furthermore, a spring is fixedly connected between the piston plate and the end wall of the piston cylinder. Furthermore, there are multiple ultraviolet lamps and piston cylinders, and the ultraviolet lamps and piston cylinders correspond to each other one by one, and the through holes on the piston cylinders are close to the corresponding ultraviolet lamps.

[0011] Compared with the prior art, the present invention has the following beneficial effects: as the threaded rod, the threaded tube and the piston plate move, the ozone on the upper part of the box is sucked into the piston cylinder and then injected into the waste liquid, thereby improving the disinfection efficiency and disinfection effect. Afterwards, the piston cylinder sucks the waste liquid and then sprays the waste liquid onto the ultraviolet lamp, thereby further improving the sterilization efficiency and sterilization effect.

[0012] The piston cylinder moves in and out of the waste liquid and in the waste liquid, which has a stirring effect on the waste liquid, helps to make the waste liquid, disinfectant solution and ozone mix more evenly, which is beneficial to improving the disinfection efficiency.

[0023] like Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: the waste sample processing device for clinical medical testing includes a box body 1, an ultraviolet lamp 5 and a piston cylinder 19.

[0024] A liquid inlet is provided on one side of the box 1, and a filter plate 3 is provided at the liquid inlet.

[0026] A fixed tube 6 is fixedly installed on the top of the box body 1, and a threaded tube 7 is provided in the fixed tube 6 for upper and lower limit movement. Specifically, a first limit block 12 is fixedly installed on the inner wall of the fixed tube 6, and a first limit groove 8 that slides with the first limit block 12 is provided on the outer wall of the threaded tube 7. A first gear ring 9 is coaxially installed in the fixed tube 6, and the first gear ring 9 is threadedly connected to the threaded tube 7. A first motor 10 is fixedly installed in the fixed tube 6, and a first gear 11 is fixedly installed on the motor shaft of the first motor 10, and the first gear 11 is meshed with the first gear ring 9. The first motor 10 drives the first gear ring 9 to rotate through the first gear 11, thereby causing the threaded tube 7 to move up and down relative to the fixed tube 6.

[0027] A threaded rod 14 is provided in the threaded tube 7 for upward and downward movement. A second limit block 13 is fixed on the inner wall of the threaded tube 7, and a second limit groove is provided on the threaded rod 14 for limited sliding cooperation with the second limit block 13. A second motor 16 is fixedly installed in the threaded tube 7, and a second gear 17 is fixedly installed on the motor shaft of the second motor 16. A second gear ring 15 is coaxially installed in the threaded tube 7 for rotation, and the second gear 17 is meshed with the second gear ring 15. The second gear ring 15 is threadedly connected to the threaded rod 14. The second motor 16 drives the second gear ring 15 to rotate through the second gear 17, thereby causing the threaded rod 14 to move upward and downward relative to the threaded tube 7, and the second limit block 13 slides in the second limit groove.

[0028] The lower ends of the threaded tube 7 and the threaded rod 14 are both extended into the box body 1. A connecting plate 18 is fixedly installed at the lower end of the threaded rod 14, and a plurality of piston cylinders 19 are installed on the connecting plate 18. The plurality of piston cylinders 19 are evenly distributed around the axis of the threaded rod 14. A through hole 21 is provided at the outward end of the piston cylinder 19. A piston plate 20 is sealingly and slidably provided inside the piston cylinder 19, and a spring 23 is fixedly connected between the end wall of the piston cylinder 19 at one end away from the through hole 21 and the piston plate 20. A pull rope 22 is fixedly connected to the piston plate 20. A threading hole connected to the piston cylinder 19 is provided on the piston cylinder 19, and the end of the pull rope 22 away from the piston plate 20 slides through the threading hole and then extends to the outside of the piston cylinder 19 and is fixedly connected to the threaded tube 7.

[0029] In this embodiment, the ultraviolet lamps 5 and the piston cylinders 19 correspond one to one, and the through holes 21 on the piston cylinders 19 are close to the corresponding ultraviolet lamps 5 .

[0030] Working principle: Initially, the piston cylinder 19 is at the upper end of the box body 1. Under the action of the spring 23, the piston plate 20 is at one end of the piston cylinder 19 close to the through hole 21.

[0031] The waste liquid to be tested is added into the box body 1 through the liquid inlet hopper 2, and disinfectant solution can also be added into the box body 1 together.

[0032] The ultraviolet lamp 5 is started, and the ultraviolet lamp 5 has the effect of sterilizing and disinfecting the waste liquid. The ultraviolet lamp 5 changes the oxygen in the air into ozone, and the ozone can disinfect the waste liquid.

[0033] The second motor 16 is started, and the second motor 16 drives the second gear ring 15 to rotate through the second gear 17, so that the threaded rod 14 moves downward relative to the threaded tube 7, and the distance between the lower end of the threaded rod 14 and the lower end of the threaded tube 7 gradually increases, and the connecting plate 18 and the piston cylinder 19 move downward. At the same time, the piston plate 20 moves away from the through hole 21, and the ozone in the upper part of the box body 1 is sucked into the piston cylinder 19 through the through hole 21.

[0034] As the piston cylinder 19 moves downward, the piston cylinder 19 enters the waste liquid. Then the first motor 10 is started, and the first motor 10 drives the first gear ring 9 to rotate through the first gear 11, thereby causing the threaded tube 7 to move downward relative to the fixed tube 6. At the same time, by causing the second motor 16 to rotate in the opposite direction, the threaded rod 14 moves upward relative to the threaded tube 7, thereby keeping the height of the piston cylinder 19 in the box body 1 unchanged. At the same time, as the threaded rod 14 moves upward relative to the threaded tube 7, the distance between the lower end of the threaded rod 14 and the lower end of the threaded tube 7 gradually decreases, and the distance between the piston cylinder 19 and the threaded tube 7 decreases. Under the action of the spring 23, the piston plate 20 slides in the direction close to the through hole 21, thereby injecting the ozone in the piston cylinder 19 into the waste liquid, so that the ozone can better sterilize the waste liquid.

[0035] When the piston plate 20 is at the end of the piston cylinder 19 close to the through hole 21, the first motor 10 rotates in the opposite direction, thereby moving the threaded tube 7 upward. At the same time, the threaded rod 14 moves downward relative to the threaded tube 7, the height of the piston cylinder 19 in the housing 1 remains unchanged, the distance between the lower end of the threaded rod 14 and the lower end of the threaded tube 7 gradually increases, and the piston plate 20 slides in the direction away from the through hole 21, sucking the waste liquid into the piston cylinder 19.

[0036] Until the threaded tube 7 moves to the top of the fixed tube 6, then the first motor 10 is stopped, and the threaded rod 14 is moved upward relative to the threaded tube 7 by the second motor 16, and the distance between the lower end of the threaded rod 14 and the lower end of the threaded tube 7 gradually decreases. At the same time, under the action of the spring 23, the piston plate 20 slides toward the direction close to the through hole 21, and then the waste liquid in the piston cylinder 19 is sprayed out, so that the waste liquid is fully in contact with the ozone in the upper part of the box body 1, thereby improving the sterilization efficiency. The waste liquid in the piston cylinder 19 is sprayed onto the ultraviolet lamp 5, and the radiation intensity near the ultraviolet lamp 5 is relatively large, which is conducive to improving the sterilization effect, and the ozone concentration near the ultraviolet lamp 5 is relatively high, which can further improve the efficiency of sterilization.

[0037] The piston cylinder 19 moves up and down in the waste liquid, stirring the waste liquid, so that the waste liquid, disinfectant solution and ozone are mixed more evenly, which is beneficial to improving the disinfection efficiency.

[0038] When the connecting plate 18 and the piston cylinder 19 move to the initial position, the threaded rod 14 moves downward relative to the threaded tube 7 again, the distance between the lower end of the threaded rod 14 and the lower end of the threaded tube 7 gradually increases, and the ozone near the ultraviolet lamp 5 is sucked into the piston cylinder 19.

[0039] With the movement of the threaded rod 14, the threaded tube 7 and the piston plate 20, the ozone in the upper part of the housing 1 is sucked into the piston cylinder 19 and then injected into the waste liquid, thereby improving the disinfection efficiency and disinfection effect. Afterwards, the piston cylinder 19 sucks the waste liquid and then sprays the waste liquid onto the ultraviolet lamp 5, thereby further improving the sterilization efficiency and sterilization effect. The piston cylinder 19 moves in and out of the waste liquid and in the waste liquid, thereby stirring the waste liquid, helping to make the waste liquid, disinfectant solution and ozone mix more evenly, thereby improving the disinfection efficiency.
