Splash-proof liquid sample collector

Abstract

The utility model provides a splash-proof liquid sample collector which comprises a collecting tube, a tube cap is arranged at the open end of the collecting tube, a sleeve cage is arranged in the collecting tube, and the sleeve cage is clamped on the inner side wall of the collecting tube; an opening is formed in the top end of the sleeve cage, and the opening in the top end of the sleeve cage is used for containing the collecting end of the cotton swab; and at least one side of the sleeve cage is hollow. By arranging the sleeve cage and clamping the sleeve cage on the inner side wall of the collecting tube, a cotton swab collecting end after a liquid sample is collected can be separated from a liquid reagent, and the cotton swab collecting end is extruded in the sleeve cage, so that on one hand, the cotton swab collecting end is prevented from sucking back the extruded liquid in the extrusion process; and on the other hand, the phenomenon that the liquid reagent with the liquid sample or the liquid sample is splashed out of the collecting pipe due to incorrect operation (for example, the cotton swab collecting end is moved up and down along the inner side wall of the collecting pipe, and the cotton swab collecting end is extruded to the inner side wall or the inner bottom wall of the collecting pipe) by an operator can be avoided.

Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, specifically to a liquid sample collector that prevents splashing. Background Technology

[0002] Liquid sample collection is a fundamental step in laboratory research and clinical diagnostics, involving the extraction of liquid substances from organisms, the environment, or industrial processes for further analysis. Liquid sample collection refers to the process of obtaining liquid substances from specific sources through a series of standardized procedures. These liquid substances may include bodily fluids (such as blood, urine, and saliva), cell culture supernatants, environmental water samples, and chemical products.

[0003] In the existing liquid sample collection process, due to the non-standard operation of the operators, liquid samples often splash during the squeezing and mixing process. Utility Model Content

[0004] The main objective of this invention is to provide a liquid sample collector that prevents splashing, thereby effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid sample collector for splash-proof liquid includes a collection tube with a cap at the open end and a cage inside the collection tube, the cage being secured to the inner wall of the collection tube.

[0007] The top of the cage has an opening for accommodating the collecting end of the cotton swab.

[0008] The cage is hollowed out on at least one side.

[0009] While adopting the above technical solutions, this utility model may also adopt or combine the following technical solutions:

[0010] As a preferred technical solution of this utility model: the collection tube has a first chamber and a second chamber forming a variable diameter, the inner diameter of the first chamber is larger than that of the second chamber, and the end of the first chamber is provided with an opening; the cage is arranged at the connection between the first chamber and the second chamber.

[0011] As a preferred technical solution of this utility model: a connecting member is provided between the cage and the inner wall of the collection tube, and the connecting member is used to fix the cage to the inner wall of the collection tube.

[0012] As a preferred technical solution of this utility model: the bottom end of the cage is provided with a bottom plate.

[0013] As a preferred technical solution of this utility model: the base plate is provided with a circular hole, the size of which is smaller than the size of the cotton swab collecting end.

[0014] As a preferred technical solution of this utility model: the open end of the collection tube is provided with a sealing film.

[0015] As a preferred technical solution of this utility model: the collection tube is filled with liquid reagent.

[0016] As a preferred technical solution of this utility model: the tube cap is provided with a tube plug, and the tube plug is provided with several ring ribs on its periphery.

[0017] As a preferred technical solution of this utility model: at least one connecting strip is provided between the cap and the collection tube.

[0018] This invention provides a splash-proof liquid sample collector with the following advantages: by setting a cage and securing the cage to the inner wall of the collection tube, the collecting end of the cotton swab after collecting the liquid sample can be separated from the liquid reagent. Furthermore, the collecting end of the cotton swab is squeezed within the cage, which prevents the squeezed liquid from being drawn back in during the squeezing process. It also prevents improper operation by the operator (e.g., moving the collecting end of the cotton swab up and down along the inner wall of the collection tube, squeezing the collecting end of the cotton swab against the inner wall or bottom wall of the collection tube) from causing the liquid reagent or liquid sample to splash out of the collection tube.

[0022] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-2 As shown, a liquid sample collector for splash-proof liquid includes a collection tube 1, a cap 4 at the open end of the collection tube 1, a cage 2 inside the collection tube 1, the cage 2 being secured to the inner side wall of the collection tube 1; the top of the cage 2 has an opening for accommodating the collection end of a cotton swab; the cage 2 is hollowed out at least on the side.

[0024] The collection tube 1 has a first chamber 11 and a second chamber 12 forming a variable diameter. The inner diameter of the first chamber 11 is larger than that of the second chamber 12, and the end of the first chamber 11 is provided with an opening. The cage 2 is disposed at the connection between the first chamber 11 and the second chamber 12. Alternatively, in other embodiments, a connector may be provided between the cage 2 and the inner wall of the collection tube 1, the connector being used to fix the cage 2 to the inner wall of the collection tube 1.

[0025] The cage 2 consists of a base plate, reinforcing ribs, and a ring. The base plate at the bottom is used to compress cotton swabs with sponge tips. In other embodiments, a circular hole can be provided on the base plate, the size of which is smaller than the size of the cotton swab collecting end, for compressing conventional cotton swabs.

[0026] The opening end of the collection tube 1 is equipped with a sealing film to hold liquid reagents inside the collection tube 1. It is necessary to ensure that when the collection tube 1 is used vertically, the liquid reagents will not submerge the bottom end of the cage 2 to achieve dry and wet separation, that is, the cotton swab collection end will not be squeezed in the liquid reagents.

[0027] The cap 4 is provided with a plug 41, and the plug 41 is provided with several ring ribs 42 on its periphery to better seal the cap 4 with the collection tube 1.

[0028] At least one connecting strip 5 is provided between the cap 4 and the collection tube 1.

[0029] Specifically, the liquid sample collector for the aforementioned splash-proof liquid can be implemented in the following manner:

[0030] In this embodiment, the liquid sample to be collected is saliva (in other embodiments, it can also be nasal fluid). When using it, the sponge tip 31 is placed in the mouth to absorb a sufficient amount of saliva, then removed from the oral cavity. The cotton swab 3 is placed into the collection tube 1, and the cotton swab 3 is pressed down to squeeze the saliva in the sponge tip 31 out under the action of the cotton swab 3 handle and the cage 2. The saliva flows down from the first chamber 11 of the collection tube 1 into the second chamber 12 of the collection tube 1. After squeezing out a sufficient amount of liquid (if the liquid volume is insufficient, sampling and squeezing can be repeated), the cotton swab 3 is removed from the cage 2 and the collection tube 1. Figure 2 As shown, place the cap 4 on the collection tube 1; when it is necessary to drip out the liquid sample, the collection tube 1 can be inverted and the outer wall of the collection tube 1 can be squeezed appropriately, and the liquid sample will drip out from the small opening of the cap 4 and drip onto the reagent plate for liquid sample detection.

[0031] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
