Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Embodiment one

As shown in Figures 1 to 4, a pleural fluid specimen collector includes

The housing assembly constitutes the main structure of the collector, and it includes a cylindrical shell 1, the tail end opening of the shell 1 is connected with a shielding piece 12, and the front end of the shell 1 is provided with a threaded butt joint hole;

The drainage assembly is installed on the front end of the housing 1, and it includes a drainage joint 2 composed of a front liquid inlet pipe 24 and a rear end liquid outlet pipe 25. The drainage joint 2 is provided with a threaded butt joint hole for matching with the front end of the housing 1 The threaded connection seat 23, and the front end of the threaded connection seat 23 is integrally connected to the limit baffle 21, the front end liquid inlet pipe 24 is located at the outer end of the shell 1, and the rear end liquid outlet pipe 25 is located in the inner cavity of the shell 1;

The collection assembly is used to collect the aspirated pleural fluid specimen, and it includes a collection tube 4 inserted in the shell 1, and the collection tube 4 is a negative pressure vacuum collection tube.

Embodiment two

As shown in Figures 1 to 4, in addition to all the technical features in Embodiment 1, this embodiment also includes:

The outer edge of the opening of the tail end of the shell 1 is integrally connected with a retaining ring 11, which can limit the hand holding the shell 1 during the operation and use of the medical staff, so that it is more convenient to place the collection tube 4 in the The rear end fluid outlet pipe 25 is used for collecting pleural fluid.

The front-end liquid inlet tube 24 is connected to the joint at the end of the drainage tube on the patient's chest wall, and the pleural fluid that needs to be collected and sampled can be directly sucked into the collection tube 4 through the drainage joint 2, without first drawing a sufficient amount of pleural fluid from the drainage tube through a syringe and then Transfer to the inspection test tube or the inspection box, which reduces the difficulty of operation.

There is a cross-shaped opening in the middle of the shielding sheet 12, which can pass through the collection tube 4 conveniently. At the same time, when the collection pipe 4 is filled with pleural fluid and removed, the shielding sheet 12 can be automatically closed to protect the inner cavity of the shell 1. , and then continue to install a new collection tube 4 for operation.

Embodiment three
