Description

A disposable sample collection bottle

technical field

The utility model relates to a disposable sample collection bottle, in particular to a disposable sample collection bottle for batch testing.

Background technique

The following background art is used to help readers understand the utility model, and should not be regarded as prior art.

At present, devices for collecting and storing liquid, solid or semi-solid samples, including those used for collecting stool samples in immunoassays, are often used by medical institutions in their daily work. Many testing institutions also need to use this kind of collection device, especially for the collection of various in vitro samples of the human body, and when many solid or semi-solid samples are directly tested, the detection of hepatitis B or uneven distribution may lead to The result is inaccurate. Therefore, pretreatment, such as dissolution or dilution, is required before being tested.

In addition, even after dissolution, some solid samples will have a lot of residues that cannot be dissolved. These residues usually float in the liquid, which will affect the accuracy of the test when sampling. Therefore, it is necessary to isolate the undissolved bulk residue.

Usually, in the traditional manual detection process, the solid sample is added to the collection device, the diluent liquid is added, and the sample is drawn for the next step of detection after manual mixing steps.

However, with the advancement and development of science and technology, automated testing has been widely used, especially in some medical institutions, which require batch processing of samples before batch testing. Therefore, some traditional collection devices for samples cannot meet this requirement.

Utility model content

The utility model provides an improved disposable sample collection bottle, which can meet the needs of automatic detection and make up for the deficiencies of the prior art. The improved sample collection device and collection bottle can automatically dissolve, dilute, mix and filter solid or semi-solid samples to provide qualified samples for the next step of detection and ensure the accuracy of detection. And while saving labor costs, it improves detection efficiency.

The disposable sample collection bottle provided by the utility model comprises a bottle body with openings at both ends, one opening end of the bottle body includes a filter net; the other opening end of the bottle body is covered by a first cover connected with a collecting part.

In some embodiments, the collection bottle further includes a second elastic cover, which covers the open end of the bottle body including the filter mesh. When the mixed sample in the bottle passes through the filter, it enters the cavity of the second cover, and the second cover is elastic, allowing the sampler of the needle tube to penetrate and reach the cavity of the second cover for sampling . The "elasticity" mentioned here means that it has the function of stretching and shrinking, and can self-close small holes or micropores, especially after being pierced by a sharp object (such as a needle tube), it can seal the periphery of the needle tube without liquid leakage.

In some embodiments, one end of the elastic second cover of the collection bottle is the bottom end. That is, the filter screen and the elastic second cover are located at the bottom of the collection bottle. Since the filter screen is arranged at the bottom of the bottle body, the collection bottle usually has ovum located at the bottom of the liquid due to the effect of gravity, so it is easy to enter the filter screen into the bottom of the bottle body, which is very beneficial to the collection of worm eggs in the sample.

In some embodiments, the filter has a one-way conduction or one-way permeation function. That is, the one-way permeable filter screen allows the liquid and/or worm eggs on the filter screen to enter the bottom of the bottle body, but the liquid and/or worm eggs cannot reversely flow from the bottom of the bottle body through the filter screen into the bottle at the top of the filter screen . In some specific embodiments, the filter screen can be a one-way permeable membrane. In some other embodiments, the filter screen includes a two-layer structure, one layer is a common filter screen structure, and the other layer is a one-way permeable membrane. The filter screen is used to isolate the large debris structure, and the permeable membrane is used to capture eggs in one direction.

In a preferred embodiment, the first cover and the second cover seal the two open ends of the collection bottle. Two caps seal the collection bottle so that the sample inside the bottle cannot leak.

The sample collection bottle in the utility model is filled with samples and buffer solutions at one end, and samples are taken at the other end by piercing the elastic cover at the bottom. The sample collection bottle with this structure can realize the collection and mixing of solid samples and the suction of liquid samples without turning over the collection bottle, and is especially suitable for automatic detection equipment.

In some specific embodiments, the collecting part can rotate relative to the first cover.

In a preferred manner, the first cover includes a first through hole for accommodating the passage and rotation of the collection component.

In another embodiment, the collecting part is a detachable structure. In a specific embodiment, the collecting rod of the collecting part passes through the first through hole of the first cover and is connected with the collecting cap located above the first cover. The detachable structure of the collecting part is convenient to be connected with the first cover and to be able to rotate relative to the first cover.

In some embodiments, the top of the collection cap includes grooves or protrusions. The groove or protrusion on the top of the collecting cap can be conveniently connected with external equipment, and the collecting part can be rotated relative to the first cover through the external equipment. The shape of the groove or the protrusion is not limited, and it is a standard that it can be matched with external connection equipment. In a specific embodiment, the top of the collecting cap has a rectangular groove.

In a specific embodiment, a sampling spoon is connected to the bottom of the collecting rod.

In another preferred manner, in order to facilitate adding diluting liquid into the bottle, the first cover includes a second through hole.

In a specific manner, the second through hole includes a sealing film or a sealing plug. The second through hole is covered with a sealing film or has a sealing plug in the through hole; the second through hole is sealed by the sealing film or the sealing plug.

Beneficial effect

Through the sample collection bottle provided by the utility model, solid or semi-solid samples can be dissolved, diluted, mixed and filtered efficiently and quickly, thereby improving detection accuracy; adapting to automation needs, improving detection efficiency and reducing costs.
