Description

Indwelling needle

Technical Field

The utility model relates to a medical supplies especially relates to a keep somewhere needle.

Background

Indwelling needles include soft catheters/cannulas that can be indwelling in blood vessels, and stainless steel puncture-guiding steel needles. When in use, the catheter and the steel needle are punctured into a blood vessel together, after the catheter completely enters the blood vessel, the steel needle is withdrawn, and only the soft catheter is left in the blood vessel so as to carry out infusion treatment. The use of the indwelling needle can reduce the pain of the patient caused by repeated venipuncture, is convenient for clinical medication, can be used for emergency treatment of critical patients, can reduce the workload of nurses and reduce the pain of the patient.

However, in the case of a conventional indwelling needle, a medical worker cannot perform a puncture at one time due to a manipulation and a blood vessel of a patient, and the indwelling needle needs to be adjusted forward and backward. In this case, the clearance of the indwelling needle is likely to change, which may affect the progress of the puncture. Therefore, it is necessary to provide a further solution to the above problems.

Detailed Description

The present invention is described in detail below with reference to various embodiments, but it should be noted that these embodiments are not intended to limit the present invention, and those skilled in the art should be able to make equivalent changes or substitutions in functions, methods, or structures according to the embodiments without departing from the scope of the present invention.

The utility model provides a remaining needle, it includes: three-way catheter seat, steel needle, needle seat;

The following describes an embodiment of the indwelling needle according to the present invention.

As shown in fig. 1 and 2, the indwelling needle of the present embodiment includes: three-way pipe seat 1, steel needle 2, needle file 3.

The three-way catheter hub 1 has: a conduit seat body 11 which is arranged in a front-back through way, and a branch pipe 12 which is connected with one side of the conduit seat body 11.

One end of the steel needle 2 is connected to the needle seat 3 and is contained in the catheter seat body 11. The needle seat 3 abuts against the end face of the other end of the catheter seat body 11. The other end of the steel needle 2 extends out of one end of the catheter holder body 11.
