Description

Negative pressure sampling drainage bag

technical field

The utility model relates to the technology of medical equipment, in particular to the technology of a negative pressure sampling and drainage bag.

Background technique

Clinically, some patients need to set up a drainage bag for drainage after surgery, and also need to sample the drainage fluid to monitor the patient's condition during the drainage process. The current drainage fluid sampling method is to open the drainage valve at the bottom of the drainage bag, release part of the drainage fluid in the bag into the sampling container, and then close the drainage valve at the bottom of the drainage bag after collecting enough volume. Drainage fluid spilled to the outside, causing pollution to the surrounding environment.

Utility model content

In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a negative pressure sampling drainage bag that can collect drainage fluid in real time and avoid the drainage fluid from spilling to the outside.

In order to solve the above technical problems, a negative pressure sampling and drainage bag provided by the present invention includes a bag body, the bottom of the bag body is provided with a drain valve for discharging the accumulated liquid in the bag body, and the top of the bag body is provided with a drain valve for discharging the accumulated liquid in the bag body. The drainage interface pipe connected to the drainage pipe is characterized in that: it also includes a negative pressure sampling ball and a sampling inlet valve;

The sampling inlet valve is a one-way valve, the negative pressure sampling ball is an elastic hollow sphere, and the negative pressure sampling ball is provided with a negative pressure port and a discharge port;

The pipe wall of the drainage interface pipe is provided with a sampling port, the liquid inlet of the sampling inlet valve is connected to the sampling port of the drainage interface pipe through the pipe fitting, and the liquid outlet of the sampling inlet valve is connected to the negative pressure of the negative pressure sampling ball through the pipe fitting. mouth;

The discharge port of the negative pressure sampling ball is provided with a sampling outlet valve for controlling the opening and closing of the discharge port.

The negative pressure sampling drainage bag provided by the utility model only needs to pinch the negative pressure sampling ball to be flat, and the drainage fluid can be collected in a closed manner, the drainage fluid can be collected in real time, and the drainage fluid can be prevented from spilling to the outside.

Description of drawings

FIG. 1 is a schematic structural diagram of a negative pressure sampling drainage bag according to an embodiment of the present invention.

Detailed ways

The embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present utility model. Any similar structures and similar changes of the present utility model shall be included in the protection of the present utility model. Scope, the commas in the present utility model all represent the relationship of and.

As shown in FIG. 1 , a negative pressure sampling drainage bag provided by an embodiment of the present invention includes a bag body 1, a negative pressure sampling ball 5, and a sampling inlet valve 6;

The bottom of the bag body 1 is provided with a drain valve 4 for discharging the accumulated liquid in the bag body, and the top of the bag body 1 is provided with a drainage interface pipe 2 for connecting the drainage pipe 3;

The sampling inlet valve 6 is a one-way valve, the negative pressure sampling ball 5 is an elastic hollow sphere, and the negative pressure sampling ball 5 is provided with a negative pressure port and a discharge port;

A sampling port is opened on the pipe wall of the drainage interface pipe 2, the liquid inlet of the sampling inlet valve 6 is connected to the sampling port of the drainage interface pipe 2 through the pipe fitting, and the liquid outlet of the sampling inlet valve 6 is connected to the negative pressure sampling through the pipe fitting. Negative pressure port of ball 5;

The discharge port of the negative pressure sampling ball 5 is provided with a sampling outlet valve 7 for controlling the opening and closing of the discharge port.

The embodiment of the present utility model is used in the occasions where the drainage fluid needs to be sampled. When in use, the drainage tube 3 is connected to the drainage interface tube 2. When sampling is required, the sampling outlet valve 7 is opened first, and then the negative pressure sampling ball 5 is squeezed flat, and then Then close the sampling outlet valve 7, and then release the negative pressure sampling ball 5;

Since the sampling inlet valve 6 is a one-way valve, when the negative pressure sampling ball 5 is squeezed, the air in the negative pressure sampling ball 5 will be discharged through the sampling outlet valve 7, and the negative pressure sampling ball 5 will gradually expand after loosening. Negative pressure suction will be generated, so that the drainage liquid is sucked through the sampling inlet valve 6. After the collection, you can use a catheter to connect to the liquid outlet of the sampling outlet valve 7, then open the sampling outlet valve 7, and squeeze the negative pressure sampling ball again. 5. The sample can be introduced into the sampling container through the catheter. After the introduction of the sample, the negative pressure sampling ball 5 is released. After the negative pressure sampling ball 5 is restored to the prototype, the sampling outlet valve 7 can be closed.
