Description

Technical Field

[0001] This utility model relates to the field of urine sediment smear technology, specifically a urine sediment smear. Background Technology

[0002] Urine sediment smear is a laboratory examination method that involves staining and microscopic observation of the precipitate after urine centrifugation to detect urinary system diseases or infections. To prepare urine sediment, a clean midstream urine sample should be collected. The urine should be centrifuged at 1000-2000 rpm for 3-5 minutes. After discarding the supernatant, approximately 0.2 ml of precipitate should be retained. The centrifuge tube should be gently shaken to thoroughly mix the precipitate with the remaining urine. The mixed sediment should be dropped onto a glass slide and spread evenly into a thin layer using a smearing rod. Finally, staining solution should be added to stain the thin layer on the smear.

[0003] However, existing urine sediment smears are typically stained using a dropper to dispense the staining solution. This method is not precise enough in terms of the volume of staining solution dispensed. Excessive staining can lead to over-staining of cells, resulting in abnormal light refraction and blurred vision. Conversely, insufficient staining can cause some cells to fail to stain, making them unobservable. Furthermore, the coverslips on existing urine sediment smears do not adhere tightly enough, allowing liquid to easily leak out. Therefore, this method does not meet current requirements. To address these issues, we propose a new urine sediment smear method. Utility Model Content

[0004] The purpose of this invention is to provide a urine sediment smear to solve the problem mentioned in the background art where the volume of the staining solution drop is not accurate enough. This results in excessive staining solution leading to over-staining of cells, which in turn causes abnormal light refraction and blurred vision. Insufficient staining solution may also cause some cells to fail to stain, making the cells unobservable. Furthermore, the existing cover slips on urine sediment smears do not adhere tightly enough to the smear, which may cause the liquid in the smear to easily flow out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a urine sediment smear, comprising a bottom glass plate, with limiting posts fixedly connected to both sides of the upper end of the bottom glass plate, a coating groove provided between the two limiting posts, a cover plate inserted into the coating groove, a vent hole vertically penetrating one side of the cover plate, a storage cavity fixedly connected to one side of the upper end of the bottom glass plate, a top plate placed at the upper end of the storage cavity, a connecting post fixedly connected to the middle of the lower end of the top plate, a blocking block fitted around the lower end of the connecting post, an isolation plate fixedly connected to the lower end of the storage cavity, a connecting hole provided in the middle of the isolation plate, the blocking block inserted into the connecting hole, a connecting groove provided at the lower end of the isolation plate, the connecting groove and the connecting hole at the upper end being connected through, and one side of the connecting groove being connected through to the coating groove.

[0006] Preferably, the upper end face of the top plate is provided with multiple through holes, and the blocking block is made of rubber material.

[0007] Preferably, a first positioning member is fixedly connected to both sides of the limiting post. The first positioning member includes a connecting strip fixedly connected to the end face of the bottom glass sheet. An elastic plate is fixedly connected to both sides of the upper end of the connecting strip. A positioning ring is fixedly connected to one end of the elastic plate. A connecting plate is fixedly connected between the two positioning rings.

[0008] Preferably, the cross-section of the positioning ring is a ring structure, and the elastic plate is made of an elastic metal material.

[0009] Preferably, the positioning ring is pressed against the upper end of the cover plate, and the vent hole and coating groove on one side of the cover plate are connected through each other.

[0010] Preferably, a second positioning element is provided on one side of the limiting post. The second positioning element includes an elastic sheet fixedly connected to the upper end of the bottom glass sheet. A plug-in plate is fixedly connected to one side of the elastic sheet, and a pull plate is fixedly connected to the upper end of the plug-in plate.

[0011] Preferably, both sides of the upper end of the cover plate are provided with insertion slots, and the insertion plate is inserted into the insertion slots.

[0012] Preferably, the cross-section of the elastic sheet is a semi-circular structure, and the elastic sheet is made of elastic metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model limits the amount of staining solution by setting up a storage cavity, wherein the internal size of the storage cavity is 0.5ml, thereby ensuring that the volume of staining solution entering the connection tank and coating tank is 0.5ml. This setting avoids excessive staining solution, which would cause cells to be stained too heavily, resulting in abnormal light refraction and blurred vision. It also avoids insufficient staining solution, which would cause some cells to fail to stain, thus making the cells unobservable.

[0015] 2. This utility model uses the elastic force of the elastic plate to press the positioning ring downwards, so that the positioning ring can be squeezed on the upper end of the cover plate. The positioning effect of the four positioning rings on the cover plate makes it difficult for the cover plate to fall off in the coating groove.

[0016] The second positioning component serves the same purpose: it pulls the plate upward, causing the overall elastic sheet to bend upward, and then inserts the cover sheet downward into the coating groove. The elasticity of the elastic sheet then allows the insertion plate at one end to be inserted into the insertion groove. The insertion between the insertion plate and the insertion groove positions the cover sheet, preventing it from detaching from the coating groove. This design allows the cover sheet to be confined in the coating groove, thereby preventing urine sediment and dyeing solution from leaking out of the coating groove. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 3 An embodiment of this utility model is provided: a urine sediment smear, including a bottom glass plate 1, with limiting posts 2 fixedly connected to both sides of the upper end of the bottom glass plate 1, a coating groove 7 provided between the two limiting posts 2, a cover plate 3 inserted inside the coating groove 7, a vent hole 6 vertically penetrating one side of the cover plate 3, and a storage cavity 5 fixedly connected to one side of the upper end of the bottom glass plate 1, wherein the cover plate 3 is inserted into the coating groove 7 between the two limiting posts 2;

[0025] The storage cavity 5 has a top plate 14 at its upper end. A connecting post 11 is fixedly connected to the middle of the lower end of the top plate 14. Blocking blocks 13 are fitted around the lower end of the connecting post 11. An isolation plate 15 is fixedly connected to the lower end of the storage cavity 5. A connecting hole 12 is provided in the middle of the isolation plate 15. The blocking blocks 13 are inserted into the connecting hole 12. A connecting groove 10 is provided at the lower end of the isolation plate 15. The connecting groove 10 and the connecting hole 12 at the upper end are connected through the groove. One side of the connecting groove 10 is connected through the coating groove 7. Multiple through holes are provided on the upper surface of the top plate 14. The blocking blocks 13 are made of rubber material.

[0026] The first positioning element 4 is fixedly connected to both sides of the limiting column 2. The first positioning element 4 includes a connecting strip 401 fixedly connected to the end face of the bottom glass plate 1. Both sides of the upper end of the connecting strip 401 are fixedly connected to elastic plates 402. One end of the elastic plate 402 is fixedly connected to a positioning ring 403. A connecting plate 404 is fixedly connected between the two positioning rings 403. The cross-section of the positioning ring 403 is set as a ring structure. The elastic plate 402 is made of elastic metal material. This setting makes the overall elastic plate 402 elastic. The positioning ring 403 is pressed against the upper end of the cover plate 3. The vent hole 6 and the coating groove 7 on one side of the cover plate 3 are connected through.

[0027] During the manufacturing process of the coating, liquid containing urine sediment needs to be applied to the surface of the coating tank 7 using a cotton swab, and the cover plate 3 is then placed inside the coating tank 7. The elasticity of the elastic plate 402 presses the positioning ring 403 downward, thereby pressing the positioning ring 403 against the upper end of the cover plate 3. The positioning effect of the four positioning rings 403 on the cover plate 3 makes it difficult for the cover plate 3 to detach from the coating tank 7.

[0028] The testing personnel insert a dropper containing staining solution through the through hole at the top of the top plate 14 into the storage chamber 5 to fill the storage chamber 5 with staining solution. Then, the testing personnel pull the entire top plate 14 upward, causing the connecting column 11 and the blocking block 13 at the bottom of the top plate 14 to move upward. The blocking block 13 moves upward and comes out from the connecting hole 12. The staining solution inside the storage chamber 5 flows downward through the connecting hole 12 into the connecting groove 10, and then flows into the coating groove 7 through the connecting groove 10. Finally, the staining solution inside the storage chamber 5 stains the cells of the urine sediment coated in the coating groove 7.

[0029] The storage chamber 5 limits the amount of staining solution. The internal size of the storage chamber 5 is 0.2 ml, which means that the volume of staining solution entering the connecting groove 10 and the coating groove 7 is 0.2 ml. This setting avoids excessive staining solution, which would cause the cells to be stained too heavily, resulting in abnormal light refraction and blurred vision. It also avoids insufficient staining solution, which would cause some cells to fail to stain and thus make the cells unobservable.

[0030] At this point, the entire smear can be mounted under a microscope for observation of urine sediment. When in use, the connecting plate 404 is moved, causing the connecting plate 404 to swing the elastic plate 402 and the connecting strip 401 to one side. This swing causes the positioning ring 403 to move laterally towards the upper end of the limiting post 2, thereby causing the positioning ring 403 to disengage from the upper end of the cover plate 3, thus ending the locking of the positioning ring 403 to the upper end of the cover plate 3. This setting and operation allow the cover plate 3 to be removed from the coating groove 7, and the inside of the coating groove 7 to be cleaned, thus preparing for the next use.

[0031] Please see Figures 4 to 5 Another embodiment of this utility model is provided: a second positioning member 8 is provided on one side of the limiting post 2. The second positioning member 8 includes an elastic sheet 801 fixedly connected to the upper end of the bottom glass sheet 1. A plug-in plate 803 is fixedly connected to one side of the elastic sheet 801. A pull plate 802 is fixedly connected to the upper end of the plug-in plate 803. Insertion grooves 9 are provided on both sides of the upper end of the cover sheet 3. The plug-in plate 803 is inserted into the insertion grooves 9. The cross-section of the elastic sheet 801 is set as a semi-arc structure. The elastic sheet 801 is made of elastic metal.

[0032] In this example, when the second positioning member 8 is used, the pull plate 802 needs to be pulled upward so that the elastic sheet 801 bends upward. Then, the cover 3 is inserted downward into the coating groove 7. Then, the elastic force of the elastic sheet 801 allows the insertion plate 803 at one end to be inserted into the insertion groove 9. The insertion between the insertion plate 803 and the insertion groove 9 can position the cover 3 and prevent the cover 3 from falling out of the coating groove 7. This setting allows the cover 3 to be confined in the coating groove 7, thereby preventing urine sediment and dyeing solution from leaking out of the coating groove 7.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
