Description

Syringe safety needle sleeve structure

The invention relates to a safety needle sleeve structure of a syringe. The safety needle sleeve is a clip which is formed by a clamping end and is combined into a sleeve structure, so that the sleeve structure can be combined with the needle seat of the syringe to cover and cover the needle. Achieve the safety of the needle can be removed laterally to avoid accidental contact with the needle.

Syringes are the most frequently used medical equipment in medical procedures. All blood and injections must be used.

In the structural design of the conventional syringe, the needle is mainly composed of a needle sleeve and a needle sleeve, and the needle is usually covered and protected by the needle sleeve, and the needle is prevented from stabbing the user. Therefore, the needle must be first operated during operation. Pulling out of the sleeve reveals that the needle is used for safety protection.

However, when the user holds the syringe with one hand and pulls the needle sleeve with the other hand, the movement of the two hands is an outwardly pulling out process, but the hands are forced to complete the extraction of the needle sleeve. The inertial force of the reverse return (the clamping force between the needle sleeve and the needle seat of the needle) is often easily accidentally stabbed by the needle at this time. Or, after the syringe is used, when the needle sleeve is re-bonded to the needle holder to cover the needle, since the diameter of the needle sleeve is not large and not every user can keep the hands stable, the accident may be stabbed by the needle. Not small, and has a lot of feeling The risk of dyeing exists, which is very dangerous.

In view of the above-mentioned shortcomings, the creator deeply feels that the linear relative structure between the conventional needle sleeve and the needle seat has great use risk. Therefore, with his years of experience in professional nursing, he actively develops and improves, and is cautious in all conditions. Under consideration, we finally created the composition of this structure, which will completely solve the problems of the application.

The utility model relates to a safety needle sleeve structure of a syringe. The safety needle sleeve is a clamped end, and the two half-shaped body is combined into a sleeve structure clip, so that the sleeve structure can be combined with the needle seat of the syringe to cover and cover the needle. Therefore, after the implementation, the following performance can be provided: since the safety needle sleeve of the present invention is combined into a sleeve structure by forming the two halves of the clip, the safety needle sleeve can be safely separated from the needle hub of the needle. The lateral pressing arm of the needle sleeve applies a force to open the sleeve structure, so that the safety needle sleeve and the needle are laterally separated, so as to avoid the safety of the needle.

The safety needle sleeve of the present invention is carried out in the manner of opening the sleeve structure when the needle seat of the needle is relatively combined, so that the safety needle sleeve and the needle are combined in a state of ninety degrees, so that the stability of the hands can be completely avoided. Unexpected injury caused by insufficient.

The outer joint surface of the two half-shaped body of the sleeve structure is designed to have a convex portion extending from the inside and the outside, so that even if the joint surface of the sleeve structure is subjected to lateral pressure, it will not be opened, so as to improve safety. The safety of the needle guard (avoiding the user from accidentally opening the sleeve structure due to the needle coming into contact with the joint surface when the safety needle is pulled out).

In order to enable your reviewers to clearly understand the structure of the creation and the functional benefits that can be achieved, the rest will be accompanied by a diagram to illustrate the examples and a detailed description of the following: This creation is a safety needle sleeve structure for syringes, mainly The safety needle sleeve 10 is a clip that forms a two-half body 11 and can be combined into a sleeve structure 1 (as shown in the first figure), and the force of the arm 12 can be pressed on the other side via the sleeve structure 1 The sleeve structure 1 is opened, so that the sleeve structure 1 can be combined with the needle seat 21 of the syringe 2 to cover and cover the needle 22 (as shown in the second and third figures), and the needle 22 is laterally removed and combined with the safety needle sleeve 10 Security.

According to the above composition design, since the safety needle sleeve 10 of the present invention is biased by the pressing arm 12 of the clip, the laterally opening and closing operation sleeve structure 1 can be combined with the needle holder 21 (such as the fourth). As shown in the figure), when the safety needle guard 10 is separated from the needle seat 21 of the needle 22, the sleeve structure 1 can be opened by the force of the pressing arm 12 of the safety needle sleeve 10, and the safety needle sleeve 10 and the needle 22 are urged. The state can be separated laterally to avoid the safety of accidental contact with the needle. Furthermore, when the safety needle sleeve 10 is relatively coupled to the needle hub 21 of the needle 22, the sleeve structure 1 can be opened by the force of the pressing arm 12, and the safety needle sleeve 10 and the needle 22 can be combined in a ninety degree state. Therefore, accidental injury caused by insufficient stability of the hands can be completely avoided.

In addition, the outer joint surface between the two halves 11 of the sleeve structure 1 is The stopper portion 111 having the inner and outer convex portions is designed to form a closed state in which the inner and outer stopper portions 111 overlap, so that even if the joint surface of the sleeve structure 1 is subjected to the lateral pressure, it is not accidentally opened, so as to raise the safety needle. The safety of the sleeve 10 prevents the user from operating the manner in which the safety needle guard 10 is pulled out, because the accidental opening of the sleeve structure 1 by the needle 22 against the joint surface causes an accident of stabbing the user.

Claims (2)

The utility model relates to a safety needle sleeve structure of a syringe. The safety needle sleeve is mainly a clamped end forming a two-half body and can be combined into a clip of a sleeve structure, and the sleeve can be opened by the biasing force of the other side of the sleeve structure. The structure is such that the sleeve structure can be combined laterally to cover the needle holder of the syringe. The safety needle sleeve structure of the syringe according to the first aspect of the invention, wherein the outer joint surfaces of the two halves are formed with inner and outer portions protruding from each other to form a closed state in which the inner and outer end portions overlap.
