Description

Storage cavity type sampling swab

Technical Field

The invention relates to the technical field of sampling swabs, in particular to a storage cavity type sampling swab.

Background

The phenomenon that the sampling is insufficient exists in the use process of the existing oral-nasal sampling swab, but in the sampling process, the situation that the sampled sampling swab is placed into a sampling position again for sampling is not allowed, and the situation that the sampled sample is polluted is mainly avoided.

Therefore, in order to ensure that the sample is collected sufficiently, the conventional sampling swab has a disadvantage that the sample is not collected sufficiently during use, and is not suitable for use. To this end, we propose a storage chamber sampling swab.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a storage cavity type sampling swab.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a store cavate sampling swab, includes the sampling head, the surface of sampling head is equipped with the drainage sand grip, offered jointly between the outside of sampling head and drainage sand grip and stored the chamber, the outside of sampling head and drainage sand grip is stained with the sampling layer jointly, the rear end of sampling head has connected gradually connecting rod, reducing pole and has held the pole, the front end of connecting rod is connected with the rear end of sampling head, the front end of reducing pole is connected with the rear end of connecting rod, the front end of holding the pole is connected with the rear end of reducing pole.

Preferably, the outer ring surface of one end of the connecting rod, which is close to the sampling head, is provided with a breaking groove, and the diameter of the end surface of the front end of the reducing rod is smaller than that of the end surface of the rear end of the reducing rod.

Preferably, the drainage sand grip is spiral ring shape, barb ring shape or horizontal pole strip, the upper and lower both ends when the drainage sand grip is spiral ring shape are connected with the upper and lower both ends of the storage chamber surface that corresponds respectively.

Preferably, the holding rod, the reducing rod, the connecting rod and the sampling head are of an integrated structure.

The storage cavity type sampling swab provided by the invention has the beneficial effects that: when the sampling swab is used, in the sampling process through the sampling swab, the holding rod is held by a hand, the sampling head is placed in the oral-nasal cavity, and then the sampling head is rotated and contacted with the inner wall of the oral-nasal cavity for multiple times, so that the collected sample can be attached to the sampling layer and can enter the storage cavity through the spiral annular, barb annular or cross rod strip drainage convex strip, and meanwhile, the spiral annular, barb annular or cross rod strip drainage convex strip on the outer surface can also store a certain amount of sample; thereby ensuring that the sampling swab obtains a sufficient amount of the object of collecting a sample during a single sampling procedure.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-5, a storage cavity type sampling swab comprises a sampling head 4, a drainage convex strip 6 is arranged on the outer surface of the sampling head 4, and a storage cavity 5 is jointly arranged between the sampling head 4 and the exterior of the drainage convex strip 6.

Sampling layer 8 is stained with jointly to the outside of sampling head 4 and drainage sand grip 6, and the rear end of sampling head 4 has connected gradually connecting rod 3, reducing pole 2 and holding rod 1, and the front end of connecting rod 3 is connected with the rear end of sampling head 4, and the front end of reducing pole 2 is connected with the rear end of connecting rod 3, and the front end of holding rod 1 is connected with the rear end of reducing pole 2.

The outer ring surface of the connecting rod 3 close to one end of the sampling head 4 is provided with a fracture groove 7, and the diameter of the front end surface of the reducing rod 2 is smaller than that of the rear end surface.

The drainage convex strip 6 is in a spiral ring shape, a barb ring shape or a cross rod strip shape, and the upper end and the lower end of the drainage convex strip 6 in the spiral ring shape are respectively connected with the upper end and the lower end of the outer surface of the corresponding storage cavity 5.

The upper end and the lower end of the spiral ring strip 6 are respectively connected with the upper end and the lower end of the outer surface of the corresponding storage cavity 5, so that a sample attached to the spiral ring strip 6 on the outer part of the sampling head 4 enters the storage cavity 5, and the collection amount is improved.

The holding rod 1, the reducing rod 2, the connecting rod 3 and the sampling head 4 are of an integrated structure.

In the invention, in the sampling process through a sampling swab, a holding rod 1 is held by a hand, a sampling head 4 is placed in an oral-nasal cavity, and then a sampling layer 8 outside the sampling head 4 and the inner wall of the oral-nasal cavity are rotated and contacted for multiple times, so that a collected sample can be attached to the sampling layer 8 and also enters a storage cavity 5 through a spiral annular, barb annular or transverse rod strip drainage convex strip 6, and meanwhile, a part of the collected sample can be stored on the spiral annular, barb annular or transverse rod strip drainage convex strip 6; thereby ensuring the purpose of obtaining a sufficient amount of collected samples in the one-time sampling process;

after sampling, the sampling head 4 is placed into the solution of the collection test tube by holding the holding rod 1 by hand, so that the collected samples on the sampling layer 8, on the spiral annular, barb annular or cross-bar-shaped drainage convex strips 6 are released into the solution, and the collected samples in the storage cavity 5 are released into the solution; the connecting rod 3 is then broken off through the breaking slot 7, the holding rod 1 together with the connecting rod 3 is discarded, and the remaining part is stored in a collection tube.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
