Description

A medical porous blood testing needle tube

technical field

The utility model relates to the technical field of medical detection, in particular to a medical porous blood detection needle tube.

Background technique

The blood test generally takes venous blood. Except for the special requirements, the venous blood test generally requires blood to be drawn in the morning. Some of the experimental results of taking have interfered. If you are an inpatient, the doctor or nurse should draw blood for you in a relatively stable state. Before drawing blood, you should try to clean the skin of the blood drawing site. The amount of blood drawn is based on the laboratory test. It depends on the difference in content and the number of items.

In the prior art, when blood is collected, the needle tube used for drawing blood is slow, and when two tubes of blood need to be drawn, different vacuum blood collection tubes need to be replaced, and the needle tube head stays in the blood vessel for a long time, which brings pain The feeling time is longer.

Utility model content

The purpose of this utility model is to solve the problem that the needle tube used in the prior art has a relatively slow blood drawing speed when collecting blood. Long, the problem that the pain feeling time that brings to the people is longer, and proposes a kind of medical porous type blood detection needle tube.

In order to achieve the above object, the utility model adopts the following technical solutions:

A medical porous blood testing needle tube, comprising a needle tube, a needle head is provided at one end of the needle tube, and a plurality of circular holes are arranged around the outer wall of the needle tube head, and the other end of the needle tube is nestedly connected with a connector, so that One side of the connector is fixedly connected with a handle, one end of the connector is provided with a piston, one end of the piston is fixedly connected with a hose, the hose runs through the piston, and the hose communicates with the connector, the One side of the hose is fixedly connected with a branch pipe, one end of the hose is provided with a hose connection cover, and one end of the branch pipe is provided with a branch pipe connection cover.

Preferably, a sleeve is provided at one end of the needle tube, a groove is provided at one end of the connector, and the needle tube is nestedly connected to the groove through the sleeve.

Preferably, one end of the needle head is sleeved with a needle head cover.

Preferably, the piston is movably connected with the connector, and the piston is made of hard plastic.

Preferably, the sectional radius of the piston is slightly larger than the sectional radius of the connector.

Preferably, the hose connection cap and the branch pipe connection cap are respectively movably connected to two different vacuum blood collection tubes.

In the utility model, first, the sleeve provided at one end of the needle tube is nested in the groove, thereby nestingly connecting the needle tube and the connector, and then one end of the piston is sleeved on one end of the connector, and one end of the piston is fixedly connected with a soft tube and branch tube, connect the hose connection cap and the branch tube connection cap at one end of the hose and the branch tube to two different vacuum blood collection tubes, then pick up the handle and connect the needle head cover with the needle head Take it off, insert the needle head into the blood vessel of the human body, the blood flows into the flexible tube and branch pipe through the multiple round holes surrounding the needle head and the outer wall of the needle head, and then flows into two different vacuum blood collection tubes to collect an appropriate amount of blood. The head can be pulled out.

By setting multiple round holes around the outer wall of the needle head, the speed of blood outflow is accelerated. By setting the flexible tube and branch tube, two different vacuum blood collection tubes are connected at the end of the flexible tube and branch tube. When two tubes of blood need to be collected, The time for replacing the vacuum blood collection tube is reduced, and the residence time of the needle tip in the blood vessel is shortened, thereby reducing pain.
