Technical Field

[0001] The utility model relates to a detection reagent, in particular to a occult blood detection reagent. Background Art

[0002] The utility model with the publication number of CN212864773U discloses a virus sampling preservation and detection composite tube; the composite tube includes: a tube body, an upper cover and a lower cover. The inner cavity of the tube body is partitioned into a main cavity, an exchange cavity and a detection cavity which are communicated with the upper opening of the tube body. The main cavity and the detection cavity are communicated through the exchange cavity; the lower cover has a sealing member extending into the exchange cavity. Rotating the lower cover drives the sealing member to rotate in the exchange cavity, so as to realize the sealing or communication of the exchange cavity connecting the main cavity and the detection cavity. The structure of the utility model is simple and practical, and the operation is simple. It can reduce the operation links of detection and save the detection cost. The utility model can not only sample and detect quickly on site, but also sample separately and detect centrally. At the same time, because the main cavity and the detection cavity are relatively sealed, there will be no cross-contamination.

[0003] The above virus sampling preservation and detection composite tube has no sampling component, so it is still not very convenient to use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a convenient occult blood detection reagent. An inner tube is coaxially arranged inside the tube body. The inner tube divides the internal space of the tube body into an inner cavity and an outer cavity. A reagent paper is arranged in the outer cavity. The inner cavity and the outer cavity are isolated by a diaphragm at the bottom of the inner tube. An upper cover is arranged at the upper port of the tube body. A sampling rod extending axially is arranged at the center of the upper cover. Pulling the easy-pull ring at the lower part of the upper cover can further press down the upper cover, and the thimble at the lower end of the sampling rod can pierce through the diaphragm, submerging the reagent line in the sampling solution. The utility model has the characteristics of reasonable structure, convenient operation, safety and hygiene.

[0005] The following technical solutions are adopted to achieve the above purpose:

[0006] A convenient occult blood detection reagent includes a tube body, and an upper cover and a bottom cover are arranged at the upper and lower ends of the tube body. It is characterized in that: an isolation part is arranged inside the tube body. The isolation part divides the internal space of the tube body into an inner cavity and an outer cavity. The inner cavity is communicated with the upper port of the tube body, and the outer cavity is communicated with the lower port of the tube body. The inner cavity is filled with a reagent solution, and a diaphragm is arranged at the bottom of the inner cavity;

[0007] The upper cover includes a cap and a connecting part. A sampling rod extending towards the bottom of the inner cavity is arranged on the cap. The end of the sampling rod has a thimble. An easy-pull ring is arranged between the cap and the connecting part. When the upper cover is fixed on the upper port of the tube body through the connecting part, the thimble cannot touch the diaphragm. Tearing off the easy-pull ring and pressing down the cap can make the thimble at the end of the sampling rod pierce through the diaphragm and communicate the inner and outer cavities; a reagent paper is arranged inside the outer cavity.

[0008] A sampling seat is provided on the cap, and the upper end of the sampling rod is integrally formed with or connected to the sampling seat.

[0009] The outer diameter of the sampling seat matches the inner diameter of the upper port of the tube body, and a sealing ring is further provided on the outer wall of the sampling seat; when the upper cover is fixed to the upper port of the tube body, the sampling seat seals the upper port of the tube body.

[0010] The tube body is of a columnar structure, and the isolation part is an inner tube. The inner tube, the tube body and the sampling rod are coaxially arranged. The outer cavity is located around the inner cavity, and the diaphragm is arranged at the bottom of the inner tube.

[0011] An inner plug is further provided at the lower port of the tube body. The inner plug seals the lower port of the tube body, and the lower part of the reagent paper is connected to the inner plug.

[0012] In the utility model, the inner tube divides the internal space of the tube body into an inner cavity and an outer cavity. The inner cavity is communicated with the upper port and filled with a reagent solution. The outer cavity is communicated with the lower port for conveniently placing the reagent paper. A sampling rod is installed on the upper cover; after sampling, the sampling rod directly extends into the inner cavity and mixes with the reagent solution in the inner cavity. After being fully dissolved, the easy-pull ring is torn off and the cap is pressed down to break the diaphragm, so that the reagent solution of the mixed sample enters the outer cavity to immerse the reagent paper, and wait for the test result. The structure design of the utility model is reasonable, which can effectively avoid cross contamination, and has the characteristics of convenient operation, safety and hygiene.

[0017] As Figures 1-4 shown, a fecal occult blood detection reagent includes a tube body 1. Upper covers 2 and bottom covers 3 are provided at the upper and lower ends of the tube body 1. The tube body 1 is of a columnar structure. An inner tube 10 is provided inside the tube body 1. The inner tube divides the internal space of the tube body into an inner cavity 11 and an outer cavity 12. The inner cavity 11 is communicated with the upper port of the tube body, and the outer cavity 12 is communicated with the lower port of the tube body. The inner cavity 11 is filled with a reagent solution, and a diaphragm 13 is provided at the bottom of the inner cavity 11.

[0018] The upper cover 2 mentioned above includes a cap 21 and a connecting part 22. A sampling seat 6 is provided on the cap 21. Two clamping ribs are provided on the sampling seat 6. A clamping groove is formed on the inner wall of the cap. The sampling seat is clamped on the cap through the cooperation of the clamping ribs and the clamping groove. The outer diameter of the sampling seat 6 matches the inner diameter of the upper port of the tube body 1. A sealing ring 61 is also provided on the outer wall of the sampling seat 6. When the upper cover 2 is screwed and fixed on the upper port of the tube body 1 through the connecting part, the sampling seat 6 seals the upper port of the tube body 1.

[0019] A sampling rod 4 extending towards the bottom of the inner cavity is provided on the sampling seat 6. The inner tube 10, the tube body 1 and the sampling rod 4 are coaxially arranged. The outer cavity 12 is located on the periphery of the inner cavity 11. The diaphragm 13 is arranged at the bottom of the inner tube 10. The upper end of the sampling rod 4 is integrally formed with or connected to the sampling seat 6. The end of the sampling rod 4 has a thimble 41. An easy-pull ring 23 is provided between the cap 21 and the connecting part 22. When the upper cover 2 is fixed on the upper port of the tube body 1 through the connecting part 22, the thimble 41 at the end of the sampling rod 4 cannot touch the diaphragm 13. By tearing off the easy-pull ring 23 and pressing down the cap 21, the thimble 41 at the end of the sampling rod 4 can pierce through the diaphragm 13 at the bottom of the inner tube 10 and connect the inner and outer cavities. An inner plug 7 is also provided at the lower port of the tube body 1. The inner plug 7 seals the lower port of the tube body 1. A reagent paper 5 is arranged inside the outer cavity 12. The lower part of the reagent paper 5 is fixed on the inner plug 7.

[0020] The using process of the present utility model is as follows: Remove the upper cover 2 from the tube body, obtain a test sample through the sampling rod 4 on the upper cover, then insert the sampling rod 4 and the test sample into the reagent solution in the inner tube and tighten the upper cover. The sampling seat 6 on the upper cover can seal the upper port of the tube body 1. Shake the tube body to accelerate the mixing of the test sample and the reagent solution. After sufficient mixing, tear off the easy-pull ring 23 to create a gap between the cap 21 and the connecting part 22, and press down the cap forcefully to make the thimble 41 at the end of the sampling rod 4 pierce through the diaphragm at the bottom of the inner tube 10. At this time, the mixed reagent solution in the inner cavity will enter the outer cavity and immerse the reagent paper 5 in the mixed reagent solution. Observe the test result after the color strip on the reagent paper 5 changes color.

[0021] The upper port of the tube body of the present utility model communicates with the inner cavity, and the lower port communicates with the outer cavity. The reagent paper 5 at the lower port is fixed by the inner plug 7. The production process is very simple. The sampling seat 6 and the sampling rod 4 are of an integral structure. The sampling seat is clamped on the cap. The structure design of the present utility model is reasonable and the production and assembly are very simple. Cross contamination can be effectively avoided during sampling and detection, and it has the characteristics of convenient operation, safety and hygiene.
