Abstract
Description
Technical Field
[0001] This application relates to the field of reagent tube technology, and more specifically, to a reagent tube for medical testing. Background Technology
[0002] In the biomedical field, liquid reagents or samples often require suitable containers for storage, processing, and transfer. These containers have a wide range of applications and are in high demand, especially in research laboratories and hospitals. Currently, the containers on the market are mainly various types of reagent tubes. According to the opening method of the reagent bottle cap, they can be divided into two categories: one is the flip-top reagent tube, which is mainly opened by flipping the cap upwards or closing it downwards; the other is the screw-on reagent tube, which is mainly opened or closed by twisting the cap clockwise or counterclockwise.
[0003] Reagent tubes are usually stored in reagent kits or test tube racks. To ensure the storage and retrieval of reagent tubes, the placement holes on the reagent kits or test tube racks are often large. After the reagent tubes are placed, they are prone to tilting, which can cause them to collide and spill liquid. Utility Model Content
[0004] To address the aforementioned issues, this application provides a reagent tube for medical testing.
[0005] The medical testing reagent tube provided in this application adopts the following technical solution:
[0006] A reagent tube for medical testing includes a reagent tube body and a reagent tube cap threaded to its top. A sleeve is sleeved to the top of the outer side wall of the reagent tube body, and a snap-fit base is inserted into the bottom end of the reagent tube body. Several external support strips are fixedly connected between the sleeve and the snap-fit base. The total length of the sleeve, the snap-fit base and the external support strips is greater than the length of the side wall of the reagent tube body.
[0007] Furthermore, the top surface of the snap-fit base is provided with a limiting slot that matches the bottom of the reagent tube body.
[0008] Furthermore, the bottom edge of the side wall of the reagent tube is provided with a limiting rib.
[0009] Furthermore, the inner wall of the limiting slot is provided with several limiting protrusions.
[0010] Furthermore, the limiting protrusions are arranged in three sets at equal intervals along the vertical direction.
[0011] Furthermore, the top of the side wall of the reagent tube body is provided with a protruding stop, and the top of the sleeve is provided with a groove that matches the stop.
[0012] Furthermore, the outer support bar has an outwardly bent portion at its center.
[0013] Furthermore, three outer support strips are provided at equal intervals.
[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] This application incorporates a support strip on the outside of the reagent tube. When the reagent kit or test tube rack has a large insertion hole that is difficult to place stably, the reagent tube is pressed down, causing its bottom end to engage with the snap-fit base. This compresses the support strip, causing it to bend outward and thus form a support. Through multi-level limiting of the limiting slot, it can adapt to insertion holes of different sizes and specifications, making it highly practical. This application has a simple structure, is easy to manufacture, and has good market prospects. Attached Figure Description

[0026] Example 1:
[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] This application discloses a reagent tube for medical testing, including a reagent tube body 1 and a reagent tube cap 2 threaded to its top. A sleeve 3 is sleeved to the top of the outer side wall of the reagent tube body 1, and a snap-fit base 4 is inserted to the bottom of the reagent tube body. A plurality of external support strips 5 are fixedly connected between the sleeve 3 and the snap-fit base 4. The total length of the sleeve 3, the snap-fit base 4 and the external support strips 5 is greater than the length of the side wall of the reagent tube body 1.
[0029] Preferably, the top surface of the snap-fit base 4 is provided with a limiting slot 41 that matches the bottom of the reagent tube body 1.
[0030] Preferably, the bottom edge of the side wall of the reagent tube body 1 is provided with a limiting rib 11.
[0031] Preferably, the inner wall of the limiting slot 41 is provided with a plurality of limiting protrusions 42.
[0032] Preferably, the limiting protrusions 42 are arranged in three sets at equal intervals along the vertical direction.
[0033] Preferably, the top of the side wall of the reagent tube body 1 is provided with a protruding stop 12, and the top of the sleeve 3 is provided with a groove 31 that matches the stop 12, which improves the stability between the sleeve 3 and the reagent tube body 1, prevents relative rotation between the two, and facilitates the unscrewing of the reagent tube cap 2.
[0034] Preferably, the outer support bar 5 has an outwardly bent portion at its center.
[0035] Preferably, the outer support strips 5 are provided in three equally spaced positions.
[0036] The implementation principle of a medical testing reagent tube in this application embodiment is as follows:
[0037] In the initial assembly state, such as Figure 1 , Figure 3 and Figure 4 As shown, the reagent tube body 1 is inserted from the top of the sleeve 3, and the bottom end of the reagent tube body 1 is fitted into the limiting slot 1 of the snap-fit base 4. The limiting rib 11 abuts against the bottom of the first-stage limiting protrusion 42 to prevent the sleeve 3, snap-fit base 4, and outer support strip 5 from falling off. During use, if the reagent kit or test tube rack insertion hole is too large to be stably placed, the reagent tube body 1 can be pressed down, such as... Figure 2 and Figure 5 As shown, the limiting rib 11 at the bottom of the reagent tube body 1 is restricted by the second or third limiting protrusion 42 in the limiting slot 41. The sleeve 3 and the snap-fit base 4 can squeeze the outer support strip 5, causing it to bend outward, thereby forming a stable support between it and the inner wall of the reagent kit or test tube rack insertion hole. Through the multi-level limiting of the limiting rib 11 at the bottom of the reagent tube body 1 by the limiting protrusion 42 in the limiting slot 41, the bending degree of the outer support strip 5 can be controlled according to the pressing depth, thereby controlling the overall support diameter. It can adapt to insertion holes of different sizes and specifications, and has high practicality. The structure of this application is simple, easy to produce, and has good market prospects.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
