Abstract

The utility model relates to the technical field of medical monitoring equipment, in particular to a novel arterial indwelling needle. The novel arterial indwelling needle is characterized by comprising an outmost puncture needle, wherein an indwelling needle is arranged in the puncture needle; an indwelling needle core is mounted in the indwelling needle; the puncture needle is provided with two lateral wings through which the novel arterial indwelling needle is held; the indwelling needle comprises a solid core at a non-hollow part at the front end and a hollow transparent part at the rear end; two side holes are formed in the joint of the hollow transparent part at the rear end and the non-hollow part at the front end; an anti-slip protrusion is arranged on the side wall of the hollow transparent part at the rear end; the tail part of the hollow transparent part at the rear end is provided with a pressure measuring device connecting port; the indwelling needle core adopts a non-hollow structure. The novel arterial indwelling needle improves the success rate of radial artery puncture and catheterization, and reduces the probability of vessel penetration, the amount of bleeding, and the disadvantages of puncture failure and injury of lining of blood vessels caused by split of the top end of a traditional indwelling needle.

Description

A kind of Novel arterial indwelling needle

Technical field

This utility model relates to medical monitoring equipment technical field, especially relates to a kind of Novel arterial indwelling needle.

Background technology

The needle of retaining on artery of clinical practice mostly at present is sleeve pipe and is placed in the design outside puncture needle, in clinical implementation process, exist tremulous pulse (being mainly to perturb arteries and veins) puncture and intubation mortality higher, hemorrhage more, the drawback larger to blood vessel injury, thereby increased patient vessel's damage, incur loss through delay patient's treatment.

Summary of the invention

The purpose of this utility model is to avoid the defect of the easy injured blood vessel of prior art that a kind of Novel arterial indwelling needle is provided, thereby effectively solves the defect existing in prior art.

For achieving the above object, the technical scheme that this utility model is taked is: described a kind of Novel arterial indwelling needle, be characterized in comprising outermost puncture needle, in puncture needle, be provided with remaining needle, remaining needle nook closing member is arranged in remaining needle, on described puncture needle, be provided with two flanks for holding pin, described remaining needle comprises solid core and the rear end hollow transparent part of the non-hollow space of front end, in the hollow transparent part of rear end, be provided with two side openings with the non-hollow space of front end joint, in the hollow transparent partial sidewall of rear end, be also provided with non-slip process, rear end hollow transparent part afterbody is provided with and connects pressure tester mouth, described remaining needle nook closing member is non-hollow structure.

Described puncture needle comprises the front end of metal material and the well-illuminated afterbody of well-illuminated material, and puncture needle afterbody is provided with blood back observation panel.

Between the described non-hollow space of remaining needle front end and puncture needle, be provided with and be convenient to observe the gap that arterial blood refluxes, movable laminating between described remaining needle rear end hollow transparent part and puncture needle, prevent that arterial blood from flowing out in a large number, described remaining needle nook closing member and remaining needle fit tightly, and the arterial blood that prevents from entering side opening flows out and play the effect of a supporting tube in a large number.

Two described flanks are used for holding pin in the time of puncture, complete after puncture, firmly to pressing, puncture needle division are come.

The flank near-end center line of two described flanks is the weak design of needle body, is convenient to the stressed rear needle body symmetry of two flanks and splits; The flank far-end center line of two flanks is closely to stick together assurance no leakage simultaneously along longitudinal section and disconnection.

The beneficial effects of the utility model are: described a kind of Novel arterial indwelling needle, the solid core of the non-hollow space of its front end can burr or splitting, thereby is convenient to put pipe, improves and puts pipe success rate, has reduced the damage of burr to tunica intima yet.Arterial puncture intubation success rate is scratched in its raising, reduces blood vessel penetration probability and amount of bleeding, reduces the top splitting of traditional remaining needle and causes puncture failure and the drawback to blood vessel damage.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is this utility model structural principle schematic diagram;

Fig. 2 is the A-A place sectional structure schematic diagram of this utility model Fig. 1.

In figure: 1. puncture needle; 2. remaining needle; 3. the non-hollow space of front end; 4. side opening; 5. remaining needle nook closing member; 6. flank; 7. non-slip process; 8. connect pressure tester mouth; 9. blood back observation panel; 10. flank near-end center line; 11. flank far-end center lines; 12. rear end hollow transparent parts.

The specific embodiment

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining this utility model, is not intended to limit scope of the present utility model.

As illustrated in fig. 1 and 2, described a kind of Novel arterial indwelling needle, be characterized in comprising outermost puncture needle 1, in puncture needle 1, be provided with remaining needle 2, remaining needle nook closing member 5 is arranged in remaining needle 2, on described puncture needle 1, be provided with two flanks 6 for holding pin, described remaining needle 2 comprises solid core and the rear end hollow transparent part 12 of the non-hollow space 3 of front end, in rear end hollow transparent part 12, be provided with two side openings 4 with the non-hollow space of front end 3 joints, on hollow transparent part 12 sidewalls of rear end, be also provided with non-slip process 7, rear end hollow transparent part 12 afterbodys are provided with and connect pressure tester mouth 8, described remaining needle nook closing member 5 is non-hollow structure.

Further, described puncture needle 1 comprises the front end of metal material and the well-illuminated afterbody of well-illuminated material, and puncture needle afterbody is provided with blood back observation panel 9.

Further, between the described remaining needle non-hollow space 3 of 2 front end and puncture needle 1, be provided with and be convenient to observe the gap that arterial blood refluxes, movable laminating between described remaining needle 2 rear end hollow transparent parts 12 and puncture needle 1, prevent that arterial blood from flowing out in a large number, described remaining needle nook closing member 5 fits tightly with remaining needle 2, and the arterial blood that prevents from entering side opening flows out and play the effect of a supporting tube in a large number.
