Detailed Description

The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the teachings of the present application, and such equivalents are intended to fall within the scope of the application as defined in the appended claims.

The case specimen collector shown in fig. 1 comprises a specimen separator 1, a medical filter screen 3, a liquid containing bottle 5, a buffer bottle 6, a drainage tube 8, a transfusion tube 9, a communicating tube 10 and a negative pressure guide tube 11. The case specimen collector is of a disposable integral structure, and the concrete structure is as follows:

the head end of the drainage tube 8 is provided with a connector 7, the connector 7 can be connected with a planing device, and the connector 7 comprises a cannula at the front end and a flat handheld part at the rear end, so that the plugging operation is convenient. The end of the drainage tube 8 is communicated with the top end of the specimen separator 1.

The specimen separator 1 is made of transparent soft rubber tube and is divided into an upper chamber and a lower chamber by a rubber isolation 2 arranged in the middle. The glue separating device is characterized in that the glue separating device 2 is of a structure with a middle recessed downwards, a liquid dropping head 4 is arranged in the middle of the glue separating device 2, and an upper cavity and a lower cavity of the sample separator 1 are communicated through the liquid dropping head 4. The inside of the upper cavity of the specimen separator 1 is provided with a medical filter screen 3, the medical filter screen 3 is in a bag shape, the bag opening of the medical filter screen 3 is communicated with the tail end of the drainage tube 8, the mesh size of the medical filter screen 3 is 80 meshes, tissue fragments generated by planing can be intercepted, and cells and blood water can pass through the medical filter screen 3. The lower chamber of the specimen separator 1 is communicated with the liquid containing bottle 5 through a perfusion tube 9, and cells and blood water passing through the medical filter screen 3 enter the liquid containing bottle 5 through the perfusion tube 9 for preservation. The sample separator 1 is used for separating and collecting samples in the process of collection, so that the samples are prevented from being polluted, the smooth operation is ensured, the sample collection amount can be observed in real time, and the sampling time is conveniently controlled.
