Description

A kind of indwelling needle blood collection connector

technical field

The utility model relates to the technical field of medical equipment, in particular to a blood collection connector for an indwelling needle.

Background technique

At present, the blood collection needles used in clinical practice are steel needles. When the patient replenishes fluid and collects blood, it is necessary to perform venipuncture at least twice. In order to reduce the pain of the patient's puncture, some nurses will connect the indwelling needle to the blood collection device for blood collection. Take out the blood collection needle, remove the original heparin cap and replace it with a Clifford connector. Disadvantages of the above operation process: 1. Increase the number of punctures, increase the pain of the patient, and is not conducive to protecting blood vessels. 2. Connecting the indwelling needle with the blood collection device prolongs the venous return path. Patients with poor blood circulation may not be able to successfully collect blood, and need to be changed. Manually drawing blood for access to a syringe increases the chance of occupational exposure and wastes heparin caps.

Utility model content

In order to achieve the above purpose, the present invention provides the following technical solutions: an indwelling needle blood collection joint, comprising a fixed tube, a joint and a protective sleeve, wherein the fixed tube, the joint and the protective sleeve are all hollow cavities, and one end of the fixed tube is a hollow cavity. A joint is provided, the inner wall of the joint is provided with an internal thread, the other end of the fixed pipe is provided with a protective sleeve, a fixed layer is arranged between the fixed pipe and the protective sleeve, and a through hole is opened on the fixed layer, One side of the fixed layer is provided with a connecting pipe, which is located in the hollow cavity of the fixed pipe. The connecting pipe extends from the fixed layer to the joint and extends out of the joint, and the other side of the fixed layer A blood-sucking needle is provided, and the blood-sucking needle is located in the protective sleeve cavity.

Preferably, the diameter of the through hole of the fixed layer is the same as the inner diameter of the connecting pipe.

Preferably, the axis of the blood-sucking needle, the fixing layer and the connecting tube are the same.

Preferably, the fixed pipe, the joint, the protective cover, the fixed layer and the connecting pipe are of an integrated structure.

Preferably, the top of the protective cover extends outward to form a force ring.

The blood collection connector of the indwelling needle made by using the technical solution of the utility model can reduce the number of punctures in the blood collection process through the blood collection connector, protect the blood vessels, improve the blood collection efficiency, and save costs at the same time.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

The present invention provides an indwelling needle blood sampling joint 2 as shown in FIG. 1 , comprising a fixed tube 1, a joint 2 and a protective cover 3, wherein the fixed tube 1, the joint 2 and the protective cover 3 are all hollow cavities, One end of the fixed pipe 1 is provided with a joint 2, the inner wall of the joint 2 is provided with an internal thread 4, the other end of the fixed pipe 1 is provided with a protective sleeve 3, and a protective sleeve 3 is disposed between the fixed pipe 1 and the protective sleeve 3. The fixed layer 5 is provided with a through hole on the fixed layer 5 , and a connecting pipe 6 is provided on one side of the fixed layer 5 , which is located in the hollow cavity of the fixed pipe 1 , and the connecting pipe 6 is formed by the fixed layer 5 . Extending to the connector 2 and protruding out of the outer side of the connector 2, the other side of the fixing layer 5 is provided with a blood-sucking needle 7, and the blood-sucking needle 7 is located in the cavity of the protective cover 3; the fixing layer 5 has a through hole The diameter is the same as the inner diameter of the connecting tube 6; the axis of the blood-sucking needle 7, the fixing layer 5 and the connecting tube 6 are the same; the fixing tube 1, the joint 2, the protective sleeve 3, the fixing layer 5 and the connecting tube 6 are One-piece structure; the top of the protective cover 3 extends outward to form a force ring 8 .

Specific use: When in use, in the process of venous blood drawing, when the needle of the indwelling needle is located inside the human body, the medical nurse inserts the connector 2 into the indwelling needle, and the inner thread 4 on the inner side of the connector 2 can be rotatably connected with the indwelling needle, The connection is stable and the sealing is strong. The connecting pipe 6 in the fixed pipe 1 extends to the side of the joint 2 and is longer than the joint 2, so that it is in contact with the bottom of the indwelling needle, and the fixed layer 5 on the connecting pipe 6 is in contact with the connecting pipe 6. A through hole is opened at the matching place, the blood-sucking needle 7 is arranged on the other side of the fixed layer 5 and is connected to the connecting tube 6, the blood-sampling tube is inserted into the blood-sucking needle 7, and blood is collected, and the protective sleeve 3 wraps the blood-sampling tube, which is effective. Prevent blood from splashing during the blood collection process, causing danger to medical staff or contaminating other supplies.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements to some of the technical features.
