Description

TECHNICAL FIELD

[0001] The utility model relates to medical detection consumable field, concretely is a specimen collection device. BACKGROUND

[0002] When carrying out detection projects such as tubercle bacillus detection, first, specimens need to be collected, then digestive fluid and other pretreatment liquids are added to the specimens, and then the specimens are treated by centrifugation. After centrifugation, the subsequent detection steps can be started. However, in the existing pretreatment process before centrifugation, the specimens need to be transferred multiple times and manually added with digestive fluid and other operations, which results in low detection efficiency. UTILITARIAN CONTENT

[0003] The utility model aims at the above problems, and provides a specimen collection device, which can improve detection efficiency.

[0004] To achieve the above purpose, the utility model adopts the technical scheme of a specimen collection device, which comprises a sampling cup, a cup cover is arranged at the cup opening of the sampling cup, an inner layer cup is arranged in the sampling cup, a pretreatment liquid is stored in the inner layer cup, and a sealing cover that can be opened during centrifugation is arranged at the cup opening of the inner layer cup. The pretreatment liquid is filled into the inner layer cup when it is delivered from the factory, so that manual addition of digestive fluid and other operations is not needed before centrifugation, and the sampling cup can be directly used as a centrifugation container, thereby improving detection efficiency.

[0005] Further, in order to facilitate the production of the sampling cup and the inner layer cup, the filling of the pretreatment liquid, and the sealing of the inner layer cup, the sampling cup and the inner layer cup are separately arranged, so that the sampling cup and the inner layer cup can be produced separately to facilitate the filling of digestive fluid and other liquids into the inner layer cup and the sealing of the inner layer cup.

[0006] Further, the inner side of the sampling cup is provided with a fastening mechanism for fastening the inner layer cup, so as to ensure that the inner layer cup will not fall off from the sampling cup during centrifugation.

[0007] Further, the sampling cup is made of transparent material to facilitate the observation of the amount of specimen by patients and detection personnel.

[0008] Further, the sampling cup is provided with a scale along the axial direction of the cup body to facilitate the accurate understanding of the amount of specimen by patients and detection personnel.

[0009] The beneficial effects of this invention are as follows: Depending on the testing item, the examinee adds the specimen to the sampling cup. For example, when testing for Mycobacterium tuberculosis, the examinee spits sputum into the sampling cup and then tightens the lid onto it. During this process, the testing personnel do not directly contact the specimen, thus improving their protection. During centrifugation, the testing personnel place the sampling cup in the centrifuge. During centrifugation, the pretreatment solution in the inner cup pushes open the sealing cap under centrifugal force, thereby processing the specimen. This process eliminates the need for adding pretreatment solution, thus improving testing efficiency. Attached Figure Description

[0012] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0013] Example 1, such as Figure 1 As shown, the structure of this embodiment is as follows: a specimen collection device, which includes a sampling cup 1, preferably made of transparent materials such as glass or polycarbonate. A scale is provided on the body of the sampling cup 1 along its axial direction. The mouth of the sampling cup 1 is equipped with a lockable lid 2, which can be locked onto the sampling cup 1 by means of threads, etc. An inner cup 3 is provided inside the sampling cup 1. The inner cup 3 is pre-filled with a pretreatment solution configured according to different testing items, such as specimen digestion solution, potassium chloride, sodium hypochlorite, etc. The inner cup 3 and the sampling cup 1 can be set as one piece. In order to avoid the pretreatment solution from undergoing a chemical reaction under light and causing deterioration or failure, the inner cup 3 is preferably made of black or other dark-colored materials. At the same time, the dark-colored inner cup 3 will not interfere with the observation of the specimen state in the sampling cup 1. Therefore, the sampling cup 1 and the inner cup 3 are set separately.

[0014] The sampling cup 1 has a fastening mechanism on its inner side for securing the inner cup 3. The fastening mechanism can be adhesive applied to the bottom outer side of the inner cup 3 or the bottom inner side of the sampling cup 1, which adheres the inner cup 3 to the sampling cup 1; or the fastening mechanism can be ribs set on the inner side wall of the sampling cup 1, with the ribs arranged in a circular array around the axis of the sampling cup 1, which hold the inner cup 3 in place; or the fastening mechanism can use a combination of ribs and adhesive, or a structure in the prior art that can fix one cup body to the inside of another cup body.

[0015] The inner layer cup 3 is provided with a seal cover 4 which can be opened in centrifugation at the cup opening of the inner layer cup 3, and the seal cover 4 can be made of a film of polyvinyl alcohol, polypropylene or the like, and is adhered to the cup opening of the inner layer cup 3 by curing glue or the like.

[0016] Specific use method: the examinee spits sputum into the sampling cup 1, then tightens the cup cover 2 on the sampling cup 1, and hands over the sampling cup 1 to the detection personnel. The detection personnel checks whether the sampling cup 1 is tightly covered, and then marks, collects and the like the sampling cup 1. The detection personnel brings the collected sampling cup 1 back to the detection center, and performs centrifugation in the centrifugal equipment of the detection center. In the centrifugation process, the pretreatment liquid in the inner layer cup 3 pushes open the seal cover 4 under the action of centrifugal force, so as to treat the specimen.
