Abstract

The utility model provides a slotted type puncture indwelling needle, which belongs to the field of medical appliances, and structurally comprises a puncture needle core which is in a tubular structure, wherein the front end of the puncture needle core is a pin head, the back end of the puncture needle core extends into a transparent window, a holding handle is formed on the transparent window, apuncture indwelling hose is covered outside the puncture needle core, and a slot communicated with the inner cavity of the puncture needle core is formed on the outer surface of the puncture needle core. When the puncture indwelling needle is used for venous puncture on patients, blood flows into the slot through the puncture needle core after a successful puncture, operators can fast give puncture success signals through the transparent puncture indwelling hose, so the continuous puncture on blood vessels by a needle is avoided, the puncture success ratio is improved, and the pain of patientsis relieved.

Description

Open flume type puncture remaining needle

(1) technical field

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of open flume type puncture remaining needle.

(2) background technology

Venous detaining needle claims the trocar again, because the soft nothing point of its trocar sheath, place to be difficult for puncturing or skidding off blood vessel in the blood vessel, can in blood vessel, keep a couple of days, at any time intravenously administrable, can reduce puncture time and intravenous extravasation, can alleviate nursing work load, increase work efficiency, and simple to operate, become the regeneration product of scalp acupuncture gradually, the main tool of clinical transfusion.

Venous detaining needle be applied to clinical after, both solved the misery of patient's repeated localised puncture, protected vein blood vessel, alleviated nurse's nursing work load, particularly critical patient again, can open venous access at any time, medication early improves salvage success rate.

But still there is following some deficiency in the puncture remaining needle of prior art:

1) because the nook closing member length of puncture remaining needle is longer, behind the punctures blood vessel, blood flow is longer through the time of the nook closing member arrival transparency window of puncture remaining needle, the operator can take for syringe needle and also not puncture blood vessel, so can continue to puncture forward, thereby blood vessel be pierced through puncture failure;

2) be positioned at and hold handle only in one-sided setting on the transparency window, use very inconveniently, only looked after the right-handed person and used the crowd, and do not considered that left hander uses the crowd.

3) hold between handle and the nook closing member and to rotate freely, after fixedly holding handle, still can not fundamentally limit the rotation of nook closing member, thus good fixed needle, bulging easily pin.

(3) summary of the invention

Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, open flume type that one-time successful puncture rate improves greatly puncture remaining needle is provided.

The technical scheme that its technical problem that solves this utility model adopts is:

Open flume type puncture remaining needle, the puncture nook closing member that comprises tubular structure, the front end of puncture nook closing member is a syringe needle, the rear end of puncture nook closing member extend in the transparency window, transparency window is provided with holds handle, coated in the outside of puncture nook closing member have puncture to keep somewhere flexible pipe, offers on the outer surface of puncture nook closing member and be equipped with the groove that communicates with the inner chamber of the nook closing member that punctures.

Above-mentioned open flume type puncture remaining needle, the handle of holding on its transparency window is symmetrical arranged on transparency window.

Above-mentioned open flume type puncture remaining needle, it holds fixedly connected or semifixed connection between handle and the puncture nook closing member.

Open flume type puncture remaining needle of the present utility model compared with prior art, the beneficial effect that is produced is: reasonable in design, simple in structure, easy to use, because puncture nook closing member fluting, can find rapidly to puncture successfully, avoid continuing the inserting needle piercing blood vessel, improve puncture success rate, alleviated the patient suffering.

(4) description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

Among the figure, 1, the puncture nook closing member, 2, transparency window, 3, hold handle, 4, puncture keeps somewhere flexible pipe, 5, groove.

(5) specific embodiment

Below in conjunction with explaining below 1 pair of open flume type puncture remaining needle work of the present utility model of accompanying drawing.

As shown in Figure 1, open flume type puncture remaining needle of the present utility model, its structure comprises the puncture nook closing member 1 of tubular structure, the front end of puncture nook closing member 1 is a syringe needle, the rear end of puncture nook closing member 1 extend in the transparency window 2, and transparency window 2 is provided with holds handle 3, holds handle 3 and is symmetrical structure and is arranged on the transparency window 2, coated in the outside of puncture nook closing member 1 have puncture to keep somewhere flexible pipe 4, offers on the outer surface of puncture nook closing member 1 and be equipped with the groove 5 that communicates with the inner chamber of the nook closing member 1 that punctures.

Above-mentioned hold handle 3 and the puncture nook closing member 1 between fixedly connected or semifixed connection.

Its processing and fabricating of open flume type puncture remaining needle of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.

Except that the described technical characterictic of description, be the known technology of those skilled in the art.
