Description

Artery puncture needle convenient to fix and prevent blood splash

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to artery pjncture needle convenient to it is fixed, prevent blood splash.

Background

Clinically, blood pressure needs to be continuously monitored for critically ill operation patients or intensive care patients, and arterial manometry is generally adopted, namely an arterial puncture needle is inserted into an artery and then connected with an arterial manometry device to immediately measure the change of arterial blood pressure. The radial artery is the first choice for measuring the pressure of the artery due to the superficial position, relative fixation, easy touch and the like. In the radial artery puncture indwelling needle process commonly used in the market at present, the following problems are difficult to solve: 1. when the arterial indwelling needle punctures and blood returns to the needle tail, the blood inevitably flows out of the body in the process of pulling out the needle core, so that blood pollution is caused, and whether the blood is arterial blood or venous blood cannot be accurately judged; 2. currently, some doctors adopt Y-type venipuncture indwelling needles, whether indwelling is successful or not can be visually judged through blood pulsation in self-contained extension tubes, blood pollution does not exist, and the Y-type venipuncture indwelling needles have obvious advantages compared with arterial indwelling needles.

Disclosure of Invention

In order to solve the problem, the utility model discloses an artery pjncture needle convenient to it is fixed, prevent blood splash adopts Y type vein puncture to keep somewhere the needle, and the adjustable snap ring of extension pipe tail end design is convenient for fix, prevent blood splash.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides an artery pjncture needle convenient to it is fixed, prevent blood splash, includes guide body, nook closing member and extension pipe, the guide body is keeping somewhere the handle and setting up at the soft needle of keeping somewhere the handle front end, keeps somewhere the inside elastic sealing body that is equipped with of handle, and the handle outside of staying is equipped with the side mouth, the side mouth sets up the one side that is close to the steel needle at elastic sealing body, the extension pipe is connected to the side mouth, extension pipe tail end is equipped with adjustable snap ring, be equipped with the recess on the adjustable snap ring, the nook closing member includes puncture handle and sets up the steel needle at puncture handle front end, inside the steel needle passes and keeps somewhere handle entering soft needle, and outside the head end that the head end of steel needle stretches out the soft needle.

As an improvement of the utility model, the side surface of the puncture handle is butterfly-shaped.

As an improvement of the utility model, the recess is square groove or circular arc groove, and the groove depth is greater than the extension pipe external diameter.

As an improvement of the utility model, the groove width is less than the extension pipe external diameter.

As an improvement of the utility model, the relative inboard of recess notch is equipped with the arc lug.

As an improvement of the utility model, the inner wall of the extension tube is provided with an anticoagulant layer.

The utility model has the advantages that:

(1) the Y-shaped vein puncture indwelling needle is adopted to replace an artery indwelling needle for puncture, and the adjustable clamping ring is designed at the tail end of the extension tube, so that the fixing is convenient, the blood splashing is prevented, and the blood pollution is avoided;

(2) when an arterial blood sample needs to be taken in the monitoring process, blood can be directly taken at a side port, and compared with the common straight needle type blood taking path, the blood taking path is short, and the liquid volume of a back flushing artery is reduced.

Fig. 2 is a schematic view of the adjustable snap ring of the present invention.

Fig. 3 is a usage state diagram of the present invention.

List of reference numerals:

1. the indwelling needle comprises an indwelling handle, 2, a soft needle, 3, an elastic closing body, 4, a side opening, 5, an extension tube, 6, an adjustable clamping ring, 7, a groove, 8, a puncture handle, 9, a steel needle, 10, an arc-shaped bump, 11 and an anticoagulant layer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in the drawing, an artery pjncture needle convenient to fix, prevent blood splash, including guide body, nook closing member and extension pipe 5, the guide body is including keeping somewhere handle 1 and setting at the soft needle 2 of keeping somewhere the handle front end, keeps somewhere that handle inside is equipped with 3 stifled inside the handle 1 of keeping somewhere of elasticity obturator, keeps somewhere that handle 1 outside is equipped with side mouth 4, side mouth 4 sets up the one side that is close to the steel needle at elasticity obturator 3, extension pipe 5 is connected to side mouth 4, extension pipe 5 tail end is equipped with adjustable snap ring 6, be equipped with recess 7 on the adjustable snap ring 6, the nook closing member is including puncture handle 8 and the steel needle 9 of setting at puncture handle front end, inside steel needle 9 passed to keep somewhere handle entering soft needle 2, and outside the head end that the head end of steel needle 9 stretches out soft needle 2.

An artery pjncture needle convenient to fix, prevent blood splash, in the position of extension pipe, design an adjustable snap ring 6, as shown in fig. 2, extract steel needle 9 after the puncture, in blood recoil entering extension pipe 5, stopped the possibility of blood splash basically, the utility model discloses an extension pipe is very long (being greater than 20 cm), can hold more blood of recoil on the one hand, on the other hand can bypass extension pipe 5 thumb department then with extension pipe embedding recess in, adjustable snap ring 6 tightens up the thumb toward thumb direction translation, live pjncture needle monolithic stationary.

The pjncture needle, when needing to get in the monitoring process and using arterial blood sample, can directly get blood at the side mouth, it is short to get the blood route than ordinary straight needle type, has reduced the liquid volume of recoil artery.

8 sides of the puncture handle are butterfly-shaped (arc-shaped or wave-shaped), so that the operator can conveniently pinch and pull out the steel needle.
