Abstract

The utility model discloses a V-shaped incision needle tube of a Y-type retained needle, which includes a needle tube, and the head part of the needle tube is provided with a needle with an oblique incision. Corresponding tangent planes are arranged on the front end of the tangent sides on the two sides of the oblique incision of the needle, the tangent planes extend towards the backside and the frontage of the needle, the two tangent planes intersect to form the needlepoint. The radial position of the needlepoint is arranged between the axis of the needle tube and the outer wall of the needle tube. The cut after the sufferer is punctured by the needle is V-shaped. The utility model can prevent the catheter from being squashed flat, can prevent the needlepoint from pricking the inner wall of the capillary catheter, and can ensure the safety and sanitation of the infusion.

Description

The V-notch needle tubing of Y type remaining needle

Technical field

This utility model relates to a kind of V-notch needle tubing of Y type remaining needle.

Background technology

Present remaining needle mainly includes puncture needle, conduit, catheter block, long duct and infusion connector assembly, and catheter block is connected rear end of conduit, and puncture needle comprises the notch needle tubing that is plugged in conduit and the catheter block, the notch needle stand that is exposed to catheter block.After medical personnel use venous indwelling at the patient's vein vascular puncture, puncture needle to be extracted from catheter block rear end and conduit, comparatively softish duct portion is kept somewhere in the patient's vein blood vessel, carries out continuously to the patient or transfusion discontinuously by conduit.Because it is flexible that soft conduit has, when remaining needle placed vein, conduit can be tortuous synchronously with vein, makes the injection site still can freely move, to alleviate the sense of discomfort of patient when using.

As Fig. 1, Fig. 2 and shown in Figure 3, the needle tubing 01 of existing puncture needle partly is provided with an angular cutouts 02 in the puncture of its head, the preceding end-grain cutting of side cut that syringe needle 03 is positioned at angular cutouts 02 both sides is provided with arc tangent plane 04, behind the patient's vein vascular puncture, patient's wound almost is in-line, therefore is easy to recover.Though the needle tubing of this puncture needle has effect preferably when being used in syringe, when it was used in remaining needle, the in-line wound resistance that this needle tubing puncture back produces was big, thus the influence puncture; In addition, because needle point 05 is to be formed on the needle tubing wall of a side, when puncture needle thrust the conduit endoporus, needle point was easy to prick a hair pipe inner wall, thus the safety and the health of influence transfusion.

Summary of the invention

This utility model purpose is: the V-notch needle tubing that a kind of Y type remaining needle is provided, wound after the patient is punctured by the syringe needle of this needle tubing is V-shaped, avoided conduit when transfusion, to be crushed, in addition, the radial position of needle point is between the outer wall of needle tubing axial line and needle tubing, therefore when puncture needle thrusts the conduit endoporus, avoid needle point to prick the hair pipe inner wall, guaranteed the safety and the health of transfusion.

The technical solution of the utility model is: a kind of V-notch needle tubing of Y type remaining needle, comprise needle tubing, the head of needle tubing is the syringe needle with angular cutouts, the front end that described syringe needle is positioned at the side cut of angular cutouts both sides is provided with corresponding tangent plane, tangent plane extends to syringe needle back and the place ahead, two tangent planes intersect the formation needle point, and the radial position of needle point is between the outer wall of needle tubing axial line and needle tubing, and the wound after the patient is punctured by syringe needle is V-shaped.

The further technical scheme of this utility model is: a kind of V-notch needle tubing of Y type remaining needle, comprise needle tubing, the head of needle tubing is the syringe needle with angular cutouts, the front end that described syringe needle is positioned at the side cut of angular cutouts both sides is provided with corresponding tangent plane, tangent plane extends to syringe needle back and the place ahead, two tangent planes intersect the formation needle point, and the radial position of needle point is between the outer wall of needle tubing axial line and needle tubing, and the wound after the patient is punctured by syringe needle is V-shaped; The front portion of described needle tubing is provided with the side channel hole that is communicated with its inner chamber.

This utility model advantage is:

1. the wound after the patient is punctured by syringe needle of the present utility model is V-shaped, has avoided conduit to be crushed when transfusion, has guaranteed to infuse and has normally carried out.

In this utility model the radial position of needle point between the outer wall of needle tubing axial line and needle tubing, therefore when puncture needle thrusts the conduit endoporus,, avoided needle point to prick a hair pipe inner wall, guaranteed the safety and the health of infusing.

3. whether this utility model is provided with the side channel hole in the front portion of needle tubing, and the side channel hole is communicated with the inner chamber of needle tubing, so can have blood flow to go out to judge whether success of pricker according to the side channel hole during pricker, has avoided pricker to be forbidden the puncture failure that brings.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further described:

Fig. 1 is the sketch map of prior art;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the partial enlarged drawing of prior art;

Wherein: 01 needle tubing; 02 angular cutouts; 03 syringe needle; 04 arc tangent plane; 05 needle point;

Fig. 4 is a sketch map of the present utility model;

Fig. 5 is the vertical view of Fig. 4;

Fig. 6 is a partial enlarged drawing of the present utility model.

Wherein: 1 needle tubing; 2 angular cutouts; 3 syringe needles, 4 tangent planes; 5 needle points; 6 needle tubing axial lines; 7 inner chambers; 8 side channel holes; 9 cut edge; 10 syringe needle backs.

The specific embodiment

Embodiment: as Fig. 4, Fig. 5 and shown in Figure 6, a kind of V-notch needle tubing of Y type remaining needle, comprise needle tubing 1, the head of needle tubing 1 is the syringe needle 3 with angular cutouts 2, the front end that syringe needle 3 is positioned at the side cut 9 of angular cutouts 2 both sides is provided with corresponding tangent plane 4, tangent plane 4 extends to syringe needle back 10 and the place ahead, two tangent planes 4 intersect formation needle point 5, the radial position of needle point 5 is between the outer wall of needle tubing axial line 6 and needle tubing 1, therefore when puncture needle thrusts the conduit endoporus, avoid needle point 5 to prick the hair pipe inner wall, guaranteed the safety and the health of transfusion.Wound after the patient is punctured by syringe needle 3 is V-shaped, has avoided conduit to be crushed when transfusion, has guaranteed to infuse and has normally carried out.

Whether the front portion of needle tubing 1 is provided with the side channel hole 8 that is communicated with its inner chamber 7, so can have blood flow to go out to judge whether success of pricker according to side channel hole 8 during pricker, has avoided pricker to be forbidden the puncture failure that brings.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
