Technical Field

The utility model belongs to the field of experimental tools, and particularly relates to a buffer bottle convenient to fix.

Background

In vitro diagnosis, i.e. ivd (invitrodiagnosis), refers to products and services that are used outside the human body to obtain clinical diagnosis information by detecting human body samples (body fluids, tissues, blood, etc.) and further determine diseases or body functions. In vitro diagnostic and test medicine forms an organic whole that is both closely related and distinct from each other. In vitro diagnostics are "tools" and "weapons" of laboratory medicine, while laboratory medicine is "users" and "markets" of the in vitro diagnostics industry, both of which have the common purpose of performing in vitro diagnostics. About 80% of clinical diagnostic information comes from in vitro diagnosis, and the cost thereof accounts for less than 20% of medical costs. In vitro diagnosis has become an increasingly important component for human disease prevention, diagnosis and treatment, and is an increasingly important component for ensuring human health and building a harmonious society.

The buffer bottle is a common instrument in a laboratory and can be used as a small-dose reagent reaction container or a storage container.

In this embodiment, in view of the problem that the bottle body used in the conventional sampling has the problems of leakage, air leakage and deterioration of the buffer solution due to the fact that the sealing cover and the bottle body are not tightly sealed, a dual-purpose sealing cover is specially arranged in this embodiment, can be used as the sealing cover to seal the buffer bottle body, can be taken down to be nested and matched with the bottom of the bottle body, and can be used as the base of the buffer bottle to fix the bottle body and prevent the experimental accident caused by the toppling of the bottle body. The dropper cap 2 in this embodiment can replace a dropper for sample application after being installed at the opening of the buffer solution.

As shown in fig. 2, when the buffer bottle provided by this embodiment is used, the sealing cap at the bottle mouth can be taken down to be nested and matched with the lower bottle body, so as to be used as a dual-purpose sealing cap, and the buffer bottle can be conveniently fixed.

As shown in fig. 3, the bottom of the inner cavity of the bottle body 1 of the present embodiment is provided with irregular protrusions, which can increase the friction force with the cotton swab.

The application process of this embodiment is as follows:

1. the dual-purpose sealing cover serving as the sealing cover at the opening of the bottle body 1 is taken down firstly, and is in nested fit with the bottom of the buffer bottle to serve as a base of the bottle body 1, so that the buffer bottle body is conveniently fixed, the bottle body 1 is prevented from being toppled over, and a reagent bottle rack is not required to be purchased additionally. It is not only suitable for laboratory, but also suitable for self-test of single-person in vitro diagnostic reagent.

2. A cotton swab carrying a test sample is inserted into the vial and brought into full contact with the buffer stored in the vial. The lower bottle body is squeezed, and the irregular bulges at the bottom of the inner cavity of the bottle body 1 are utilized, so that the sample carried on the cotton swab is released more thoroughly.

3. After the sample is completely dissolved in the bottle body, the dropper cap 2 is covered, and a proper amount of sample solution is directly dripped into the in-vitro diagnostic reagent sample adding hole through the dripping hole of the dropper cap without additionally purchasing a dropper for sample adding.

Example 2

As shown in fig. 6, a buffer bottle convenient for fixing, this embodiment is different from embodiment 1 in that: the position that the inner wall of bottle 1 is close to the opening is equipped with tectorial membrane 6 for seal the buffer bottle inner chamber and store the region of solution, prevent the weeping in the transportation. The distance between the covering film and the bottle mouth is larger than or equal to the depth (namely the length of the supporting groove body) of the dual-purpose sealing cover embedded into the bottle body when the dual-purpose sealing cover is installed at the opening of the bottle body, so that the dual-purpose sealing cover is prevented from being influenced by the existence of the covering film at the opening of the bottle body.

The application process of this embodiment is as follows:

1. whether the liquid is less or not and the liquid leakage condition is checked through the scale line type anti-slip lines. The coating film 3 is then peeled off. 2. A cotton swab carrying the test sample is inserted into the vial and allowed to fully contact the buffer. The irregular bulges at the bottom of the inner cavity of the bottle body 1 are utilized to ensure that the sample carried on the cotton swab is released more thoroughly. 3. After the sample is completely dissolved in the bottle body, the dropper cap 2 is covered, and a proper amount of sample solution is directly dripped into the in-vitro diagnostic reagent sample adding hole through the dripping hole of the dropper cap without additionally purchasing a dropper for sample adding. 4. In the subsequent experiment process, if the bottle body needs to be temporarily closed, the dual-purpose sealing cover at the bottom of the bottle is taken down and is nested and matched with the bottle opening.

Example 3

The buffer bottle convenient to fix is different from the buffer bottle in embodiment 1 in that: the outer side of the bottle body is provided with external threads at the end part close to the opening. Correspondingly, the inner side walls of the dual-purpose sealing cover and the dropper cap 2 are provided with internal threads; both the dual purpose closure and the drip cup 2 can be threadably connected to the opening of the bottle body 1, rather than the nesting fit connection of example 1. In the initial state, the dual-purpose sealing cover is in threaded connection with the opening of the bottle body 1 to seal the bottle body and prevent liquid leakage in the transportation process. When in use, the dual-purpose sealing cover is taken down, and the supporting groove body in the dual-purpose sealing cover is nested and matched with the bottom surface of the bottle body 1 to be used as a buffer bottle base.

The application process of this embodiment is as follows:

1. whether the liquid is less or not and the liquid leakage condition is checked through the scale line type anti-skidding lines.

(rotate and unscrew) take off the dual-purpose closing cap that is located 1 opening part of bottle to it cooperates with buffering bottle bottom nestification, as the base of bottle 1, plays the fixed action to the buffering bottle conveniently, prevents that bottle 1 from empting.

3. A cotton swab carrying a test sample is inserted into the vial and brought into full contact with the buffer stored in the vial. The lower bottle body is squeezed, and the irregular bulges at the bottom of the inner cavity of the bottle body 1 are utilized, so that the sample carried on the cotton swab is released more thoroughly.

4. After the sample is completely dissolved in the bottle body, the dropper cap is covered (the connecting strip is disconnected, the dropper cap is taken down), and a proper amount of sample solution is directly dripped into the in-vitro diagnostic reagent adding hole through the dripping hole of the dropper cap.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should take the description as a whole, and the technical solutions in the embodiments may be appropriately combined to form other embodiments understood by those skilled in the art.
