Description

Technical Field

[0001] The invention relates to the technical field of sterilization treatment, in particular to a urine sample sterilization treatment device. Background Art

[0002] Urinalysis specimen refers to the urine sample collected during urinalysis. Urinalysis is an important means of diagnosing various diseases, and the test results are an important basis for diagnosing diseases. Urine sample sterilization treatment device is a device used to treat urine samples, aiming to eliminate bacteria, viruses and other pathogens in them to ensure the sterility of the samples. Such devices are widely used in medical laboratories, clinical diagnosis and research institutions.

[0003] At present, urine sample sterilization treatment devices on the market include but are not limited to high temperature sterilization, ultraviolet sterilization and disinfectant sterilization treatment. For example, the Chinese utility model patent with the publication number of CN221206224U discloses a urine sample sterilization treatment device, which can effectively sterilize and disinfect by placing the urine sample in a sample box and rotating the rotating disk under the irradiation of the ultraviolet sterilization lamp and the heating plate, while maintaining the uniformity of the sample. By rotating the sample box, the urine sample can be evenly exposed to the irradiation of the ultraviolet lamp and the heating plate to ensure the uniformity of the sample treatment effect. In addition, the urine sample sterilization treatment device does not need to clean the entire device, only the sample box needs to be replaced, which means that a large amount of detergent, water and energy are not required for cleaning the entire device, which helps to save the resources required for cleaning and disinfection and reduce the idle time during the sample processing process. However, in actual use, the urine sample container is small, and only one sample container can be placed in the sample box at a time, resulting in low efficiency.

[0041] Urine sample sterilization processing devices are equipment used to process urine samples, aiming to eliminate bacteria, viruses and other pathogens therein to ensure the sterility of the samples. Such devices are widely used in medical laboratories, clinical diagnostics and research institutions.

[0042] In the related art, by placing a urine sample in a sample box and rotating a rotating disk, and processing it under the irradiation of an ultraviolet sterilization lamp and a heating plate, it can be effectively sterilized and disinfected while maintaining the uniformity of the sample. By rotating the sample box, the urine sample can be evenly exposed to the irradiation of the ultraviolet lamp and the heating plate to ensure the uniformity of the sample processing effect. In addition, the urine sample sterilization processing device does not need to clean the entire device, only the sample box needs to be replaced, which means that a large amount of detergent, water and energy are not required to clean the entire device, which helps to save the resources required for cleaning and disinfection and reduce idle time during the sample processing process. However, in actual use, the urine sample container is small, and only one sample container can be placed in the sample box at a time, resulting in low efficiency. At the same time, during the rotation of the sample box, the sample container cannot be effectively limited, which brings inconvenience to subsequent use.

[0043] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a urine sample sterilization processing device. When in use, it is only necessary to lift the baffle 14 to expose the placement rack 11, insert the urine sample container between the clamp 1 22 and the clamp 2 23, limit the urine sample container, turn on the ultraviolet lamp on the top surface of the workbench 10, and sterilize the urine sample. It is more convenient and quick, and improves the convenience of the device.

[0044] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0045] Combination Figure 1-Figure 5The present application embodiment provides a urine sample sterilization treatment device, comprising: a workbench 10, a placement rack 11 is arranged inside the workbench 10, an exhaust pipe 12 is arranged on the side of the workbench 10, an adsorption box 13 is arranged on the top of the workbench 10, one end of the exhaust pipe 12 is connected to the adsorption box 13, a baffle 14 is slidably connected to the workbench 10, an ultraviolet lamp 15 is fixedly connected inside the workbench 10, a plate body 20 is fixedly connected inside the placement rack 11, a sliding mechanism 21 is arranged inside the plate body 20, a clamping plate 23 is fixedly connected to the outer end of the exhaust pipe 12, and the sliding mechanism 21 is used to adjust the position of the clamping plate 23, and ... There is a clamping plate 22, a threaded rod 24 is threadedly connected to the plate body 20, a push plate 25 is slidably connected in the plate body 20, the push plate 25 is threadedly connected to the threaded rod 24, the push plate 25 is used to press against the sliding mechanism 21, a positioning rod 26 is fixedly connected in the plate body 20, the positioning rod 26 passes through the push plate 25, a slide groove 31 is opened in the workbench 10, a mounting block 30 is slidably connected in the slide groove 31, the placement frame 11 is rotatably connected to the top of the mounting block 30, a cylinder 41 is arranged at the bottom of the push plate 25, a groove 40 is opened in the mounting block 30, and the cylinder 41 presses against the workbench 10 after passing through the cylinder 41.

[0046] After the workbench 10 is placed at the designated position, the baffle plate 14 is lifted upwards to make the baffle plate 14 slide on the workbench 10, and the placement rack 11 is leaked. Subsequently, the urine sample container is inserted between the clamp plate 1 22 and the clamp plate 23, and the urine sample container is limited and fixed by the sliding mechanism 21. After multiple urine sample containers can be limited and fixed in sequence at the same time, the threaded rod 24 is rotated to make the threaded rod 24 connected with the push plate 25 through the thread, so that the push plate 25 slides downward in the plate body 1 20. While sliding, the positioning rod 26 limits the push plate 25, so that the push plate 25 can only slide longitudinally, until the push plate 25 is tightly pressed against the sliding mechanism 21, and the positions of multiple clamp plates 1 22 are limited and fixed, thereby preventing the urine sample container from shifting and affecting normal use. Finally, the ultraviolet lamp 15 is turned on to sterilize the urine sample in the urine sample container.

[0047] Before placing the urine sample container, pull the mounting block 30 outwards to make the mounting block 30 slide outwards from the slide slot 31, and at the same time, move the plate body 1 20 and its upper mechanism to slide outwards, and finally make the placement rack 11 slide out of the workbench 10, so that the staff can insert the urine sample container between the clamping plate 1 22 and the clamping plate 2 23;

[0048] Before or after placing the urine sample container, the threaded rod 24 is rotated to make the push plate 25 slide downward, and at the same time, the cylinder 41 is pushed downward in the groove 40, until the push plate 25 contacts the sliding mechanism 21, and at the same time, the cylinder 41 is pressed against the workbench 10, thereby limiting and fixing the position of the clamping plate 23 and limiting and fixing the front and rear positions of the mounting block 30 (reference direction). Figure 4 ).

[0049] Specifically, the slide groove 31 is a dovetail slide groove, which prevents the mounting block 30 from sliding upward out of the slide groove 31 .

[0050] In some embodiments, the adsorption box 13 is an activated carbon adsorption box, and the air exhausted from the exhaust pipe 12 is purified by the activated carbon in the adsorption box 13, thereby improving safety.

[0051] Specifically, a mechanical valve is provided on the exhaust pipe 12 to achieve blocking of the exhaust pipe 12 , thereby facilitating cleaning and maintenance of the adsorption box 13 .

[0052] In some embodiments, a sealing gasket is disposed on the baffle 14 so that the baffle 14 covers the workbench 10 and contacts the workbench 10 through the sealing plug, thereby improving the sealing effect.

[0053] In some embodiments, the sliding mechanism 21 includes: a plate body 211 fixedly connected to the plate body 20; a rod body 212 fixedly connected to the outside of the plate body 211; a rod body 213 slidably connected to the outside of the rod body 212; a spring 214 is sleeved on the outside of the rod body 212, and the two ends of the spring 214 are respectively fixedly connected to the plate body 211 and the rod body 213, and the outer end of the rod body 213 is fixedly connected to the splint 23.

[0054] When the urine sample container is inserted between the first clamp plate 22 and the second clamp plate 23, the second clamp plate 23 pushes the second rod body 213 to slide into the first plate 20. The second rod body 213 is limited by the first clamp plate 212, and the second rod body 213 squeezes the spring 214 until the urine sample container is inserted between the first clamp plate 22 and the second clamp plate 23. The rebound force of the spring 214 clamps the urine sample container between the first clamp plate 22 and the second clamp plate 23 to complete the placement.

[0055] In some embodiments, the outer side of the second rod body 213 is fixedly connected to a limiting block 215 , and the limiting block 215 limits the second rod body 213 to prevent the second rod body 213 from being separated from the first rod body 212 .

[0056] In some embodiments, the rod body 1 212 , the rod body 213 , the spring 214 , the limit block 215 , the clamp plate 1 22 and the clamp plate 2 23 are a group, and multiple groups are arranged on the plate body 1 20 .

[0057] The resilience of the multiple springs 214 acts between the multiple clamping plates 1 22 and the multiple clamping plates 23 , thereby clamping and limiting multiple urine sample containers of different sizes at the same time.

[0058] In some embodiments, a motor 50 is slidably connected inside the workbench 10, a gear 1 51 is fixedly connected to the output end of the motor 50, a gear 2 52 is fixedly connected to the outer side of the placement rack 11, and the gear 1 51 is meshed with the gear 2 52.

[0059] The motor 50 is turned on, and the output end of the motor 50 drives the gear 1 51 to rotate. At the same time, through the engagement with the gear 2 52, the gear 2 52 drives the placement rack 11 to rotate, so that the placement rack 11 drives the multiple urine sample containers inside it to move, so that the urine sample is in a moving state, which is convenient for the ultraviolet lamp 15 to sterilize the urine sample.

[0060] In some embodiments, the cylinder 41 is rotatably connected to the push plate 25 .

[0061] Pull the mounting block 30 forward, insert the urine sample between the clamp plate 1 22 and the clamp plate 2 23, and then push the mounting block 30 backward until the gear 2 52 on the outside of the placement rack 11 is meshed with the gear 1 51, and then rotate the threaded rod 24, and limit the mounting block 30 by means of the cylinder 41 being pressed against the workbench 10. At the same time, after turning on the motor 50, the placement rack 11 is rotated on the mounting block 30 through the meshing of gear 1 51 and gear 2 52. At the same time, because the cylinder 41 is pressed against the workbench 10, the push plate 25 is rotated in place, and the angle of the cylinder 41 remains unchanged, which does not affect the normal rotation of the placement rack 11 and can also have a good limiting effect on the mounting block 30.

[0062] In some embodiments, a fixing block 1 32 is fixedly connected to the side of the mounting block 30, and a fixing block 2 33 is fixedly connected to the inner side of the workbench 10. When the mounting block 30 slides outward, the fixing block 1 32 is limited by the fixing block 2 33 to prevent the mounting block 30 from sliding out of the slide groove 31, thereby improving safety.

[0063] In some embodiments, the positioning rod 26 is located between two adjacent rod bodies 212 to prevent the positioning rod 26 from affecting the normal sliding of the rod body 213 .

[0064] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.

[0065] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0066] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
