SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that other people are easily accidentally injured when the needle head is pulled out in the prior art, so that safety protection cannot be carried out, and the anti-acupuncture venous indwelling needle which is simple in structure and easy to use is provided.

The utility model adopts the technical scheme as follows:

the anti-acupuncture venous indwelling needle comprises a catheter seat, an isolation plug and a needle point protection clamp, wherein a groove is formed in the isolation plug, a structure which is mutually clamped with the isolation plug is arranged in the catheter seat and connected with the front part of the groove of the isolation plug, the isolation plug is limited through the groove, a U-shaped opening is formed in the rear end of the isolation plug, and the front end of the needle point protection clamp is connected with the U-shaped opening.

Furthermore, the needle tip protection clamp comprises a left clamping piece and a right clamping piece, the rear ends of the left clamping piece and the right clamping piece are connected, and a limiting through hole is formed in the connecting position.

Further, left side clamping piece and right clamping piece are equipped with the kink, the kink block is in U type opening part.

Furthermore, the clamping jaw of the left clamping piece and the clamping jaw of the right clamping piece are made of elastic materials.

Further, the utility model discloses still include a steel needle that has the indentation, the steel needle is installed in the pipe seat.

Furthermore, the diameter of the limiting through hole is smaller than that of the steel needle indentation.

Furthermore, the side surface of the catheter seat is also provided with an infusion port connected with an infusion tube.

Compared with the prior art, the utility model, its advantage lies in: overall structure is simple, compares with prior art, only protects the thorn effect that presss from both sides through the needle point in the isolation stopper can realize the syringe needle.

Detailed Description

The technical solution adopted by the present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1 and 2, for the utility model discloses a prevent acupuncture vein and keep somewhere needle, should prevent that acupuncture vein keeps somewhere needle include, pipe seat 1, isolation stopper 2, steel needle 3 and needle point and protect and press from both sides 4, wherein steel needle 3 follows needle point is protected and is pressed from both sides 4 bottom through-holes and penetrate, through isolation stopper 2, wears out from pipe seat 1 top, is equipped with isolation stopper 2 parcel in the lower part of pipe seat 1, pipe seat 1 lower part is loudspeaker form opening to it is spacing through the recess on the isolation stopper 2 pipe seat 3 side is equipped with an infusion mouth.

As shown in fig. 3 again, do the utility model discloses well isolation plug 2's structural schematic diagram, be equipped with the recess on isolation plug 2, pipe seat 1 rear end cover is in it is spacing through the recess in isolation plug recess front portion, isolation plug 2 bottom is equipped with U type opening, and U type both sides are equipped with the fender bone, needle point protection clamp 4 front end with U type opening is connected, and U type opening is made by elastic material.

As shown in fig. 4 the needle tip protection clip 4 comprises a left clip piece 41 and a right clip piece 42, the top of the front end of the left clip piece 41 and the top of the right clip piece 42 are overlapped with each other, the rear ends of the left clip piece 41 and the right clip piece 42 are connected with each other, a limiting through hole is arranged in the center of the connection part of the rear ends, the top of the clamping opening of the left clip piece 41 and the right clip piece 42 is made of elastic material and can be bent towards.
