Description

Puncture-proof injection needle

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to a puncture-proof injection needle.

Background

In clinical work, injection of drugs and blood drawing tests are commonly used in western medicine as a treatment means.

The injection needle mainly includes muscle syringe needle, intravenous route needle, these medical injection needles such as vein indwelling needle all are hollow stainless steel needles, and is very sharp, and medical personnel takes place when taking out the needle after carrying out puncture treatment to the patient, and the accident that accidentally stabs oneself takes place by accident, all carries various germ in patient's body fluid and the blood usually, and the pjncture needle after being contaminated pierces medical personnel and can cause the influence for medical personnel's health undoubtedly.

In addition, if the needle point of the abandoned puncture needle is exposed outside, the collection and treatment personnel of medical waste are easy to stab, and the health of the personnel is also influenced.

CN 205095167U discloses a "needle sheath of preventing stinging", can form the needle cover piece of cladding syringe needle and needle body including two closed backs, can get up the syringe needle cladding when using and use, in the needle cover is retrieved with the syringe needle again to the locking after using up, and protect, thereby avoid stabbing the nursing staff, this kind of "needle sheath of preventing stinging" can solve the problem that the mistake stabbed, but the structure is comparatively complicated, and is with high costs, and it is also not convenient enough to operate.

CN 105833388A discloses a "safety indwelling needle", which is relatively complicated in structure, and is provided with an indwelling needle safety unit, so that a puncture needle can be hidden in a cannula, and thus an operator or other persons can be prevented from being injured by the puncture needle that has punctured a patient, and the safety of the use of the indwelling needle is increased.

In addition, there is a case where, after the puncture, the inner needle is drawn into the needle hub via a spring by pressing a button provided in the indwelling needle, and is received therein (for example, JP hei 10-52499, patent application publication No. CN 102512728A); a spring type needle point protecting mechanism is provided inside the outer needle hub, and when the inner needle is drawn out, the needle point protecting mechanism is separated from the outer needle hub and covers the tip of the inner needle (for example, patent publication No. CN 101011613 a); these all need use the spring to realize, if the spring can't deform to reset smoothly, then can't realize the protection to the steel needle point, consequently reliable inadequately, at present, lack a safe and reliable, simple structure, convenient to use's puncture-proof syringe needle.

Disclosure of Invention

The invention aims to solve the technical problem of providing the puncture-proof injection needle, which can be conveniently sleeved into a needle sleeve without aligning the needle sleeve and using a spring after being used, is safe and reliable, is more convenient to use, has a simpler structure and is low in cost.

In order to solve the technical problems, the invention adopts the technical scheme that: including needle file, needle body and needle point, its characterized in that: the joint of the outer side of the needle body and the needle seat is provided with a telescopic sleeve, and the other end of the telescopic sleeve is provided with a sleeve cap.

The telescopic sleeve can be made of elastic or soft materials such as rubber or non-woven fabrics, and the needle point is pricked on the sleeve cap after being stretched.

The needle can also be made of plastic materials, the middle part of the telescopic sleeve is provided with a longitudinal telescopic sleeve crack, the stretched needle body is pulled into the needle sleeve through the crack, and then the needle tip is pricked on the sleeve cap.

As an improvement of the second technical scheme, an upper opening hole is formed in the upper end of the crack of the telescopic sleeve, a lower opening hole is formed in the lower end of the crack of the telescopic sleeve, and the needle body can be more easily retracted into the telescopic sleeve.

As a further improvement, a transverse upper gap is arranged at the upper gap hole, and a transverse lower gap is arranged at the lower gap hole, so that the folding is easier.

As a further improvement, a splayed opening is arranged at the middle section between the upper split and the lower split, and the middle part of the telescopic sleeve is easier to fold.

As a further improvement, the handle is arranged on the side surface of the cap sleeve, so that the hand is not easy to prick.

The invention has the advantages that the telescopic sleeve is arranged at the joint of the outer side of the needle body and the needle base, the sleeve cap is arranged at the other end of the telescopic sleeve, the telescopic sleeve and the sleeve cap are both retracted at the rear end of the needle body before use, the normal use of the injection needle is not influenced, after the injection needle is pulled out, the sleeve cap is pinched by fingers to draw the needle body into the telescopic sleeve, and the needle tip is inserted into the sleeve cap to prevent medical personnel and related personnel from being punctured by mistake.
