Description

Y-shaped closed venous indwelling needle capable of withdrawing needle by single hand

Technical Field

The utility model relates to the field of medical instruments, in particular to a Y-shaped closed venous indwelling needle capable of withdrawing a needle by one hand.

Background

Intravenous infusion is the most common medical treatment means, and the basic principle is to input liquid into the venous blood vessel of a human body through an infusion pipeline and a hollow needle. When infusion is started, the hollow needle needs to be punctured into a vein. The puncture process needs to be repeated every time due to the need of repeated infusion.

In order to protect the blood vessel, the blood vessel injury and the mental pain of the patient caused by repeated puncture are reduced; the patient can move and carry the infusion bag easily, and the infusion leakage is reduced; the vein channel is kept smooth at any time, so that the medicine is convenient to be administered in time and emergently rescued; the workload of nurses is reduced, and the working efficiency is improved. Therefore, indwelling needles have been widely used clinically in recent years.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model provides a Y-shaped closed indwelling needle capable of withdrawing the needle with one hand, and the indwelling needle can carry out needle withdrawing operation with one hand so as to meet the requirements of medical care personnel.

In order to achieve the purpose, the utility model provides the following technical scheme: the Y-shaped closed indwelling needle capable of withdrawing the needle by one hand comprises a Y-shaped catheter seat and a steel needle seat connected to the Y-shaped catheter seat, wherein a steel needle is fixed on the Y-shaped steel needle seat and penetrates through the Y-shaped catheter seat and the catheter; the rear end of the steel needle base is also provided with a straight handle, and the Y-shaped catheter base is provided with a lug.

And (3) pin inserting operation: the thumb and the middle finger clamp the straight handle, and the index finger presses the lug and pushes the lug backwards so as to perform the pin inserting action; needle withdrawing operation: the thumb and the middle finger clamp the straight handle, the index finger presses the lug, the straight handle is pulled backwards through the thumb and the middle finger, and the steel needle is further pulled out from the Y-shaped catheter seat to complete the needle withdrawing action. The indwelling needle is simple in structure and convenient and quick to operate by one hand.

Preferably, the straight handle is inserted and connected into a whole along the axial direction of the Y-shaped catheter seat.

Preferably, both sides of the straight handle are designed into concave arc needle holding surfaces; a plurality of anti-slip strips are arranged on the arc needle holding surface.

Preferably, the steel needle seat and the straight handle are integrally formed.

Preferably, the front end of the straight handle extends with a lug which is integrally formed with the Y-shaped catheter holder.

In conclusion, the utility model has the following beneficial effects:

the clinical use requires an indwelling needle: safety, effectiveness, practicality, ease of use. On the premise of ensuring safety and effectiveness, the utility model is innovated and improved in practicability, particularly in usability, so that the Y-shaped closed indwelling needle only can be held by a side wing, and a straight needle holding handle and a lug on a catheter seat are added, so that the venous puncture can be completed by one hand like a pen-holder indwelling needle, the catheter is pushed to go deep into a vein, and a steel needle is withdrawn, and three standard operations are carried out.

The application is innovated, and practicality and ease of use design make traditional Y type closed keep somewhere the needle and be suitable for flank needle-holding operation promptly, have increased again if the pen-holder type keeps somewhere needle one-hand operation and accomplishes venipuncture, propelling movement pipe and withdraw from the steel needle.

Detailed Description

The utility model is further described with reference to the accompanying drawings.

Example 1: the embodiment discloses a Y-shaped closed indwelling needle capable of withdrawing the needle by one hand, which comprises a catheter 1, an outer needle tube 2, a Y-shaped catheter holder 3 and a steel needle holder connected to the Y-shaped catheter holder 3, wherein the steel needle holder is inserted at the rear end of the Y-shaped catheter holder 3; the front end of Y type pipe seat 3 cup joints pipe 1, and the front end of Y type pipe seat 3 still fixes outer needle tubing 2, is fixed with steel needle 5 on the steel needle file, and steel needle 5 runs through Y type pipe seat 3 and pipe 1, and steel needle 5 and outer needle tubing 2 set up in the lumen of pipe 1, and straight formula handle 9 is still installed to the rear end of steel needle file, is equipped with one on the Y type pipe seat 3 and straight formula handle 9 matched with lug 7.

And (3) pin inserting operation: the thumb and the middle finger clamp the straight handle 9, the forefinger presses the lug 7 and pushes the lug 7 backwards, and then the pin inserting action can be carried out; needle withdrawing operation: the thumb and the middle finger clamp the straight handle 9, the index finger presses the lug 7, and the straight handle 9 is pulled backwards through the thumb and the middle finger, so that the steel needle 5 is pulled out from the Y-shaped catheter seat 3 to complete the needle withdrawing action. The indwelling needle is simple in structure and convenient and quick to operate by one hand.

In some embodiments, the straight handle 9 is integrally inserted along the axial direction of the Y-shaped catheter hub 3. The straight handle 9 is inserted and connected with the Y-shaped catheter seat 3 into a whole along the axial direction of the Y-shaped catheter seat 3. Meanwhile, both sides of the straight handle 9 are designed into concave arc needle holding surfaces 6; a plurality of anti-skid strips 8 are arranged on the arc needle holding surface 6. Therefore, the medical staff can be prevented from sliding relative to the straight handle 9 in the process of withdrawing the needle.

Wherein, the steel needle seat and the straight handle 9 are integrally formed. Thus, the number of parts can be reduced, and the production and the assembly are convenient. In addition, the front end of the straight handle 9 extends to a lug 7 which is integrally formed with the Y-shaped catheter hub 3.
