Background

In the 80's last century, after the first instance of AIDS was discovered in the United states, the world health organization WHO proposed "three principles of safe injection" requiring the study and use of disposable safety injection needles. However, for technical reasons, in the international society, self-destruction syringes are often produced by a method of restricting the syringe outer cylinder and the plunger, or a method of piercing the piston or breaking the plunger, and the reuse of the syringe is restricted. The needle point of the injection is still exposed, so that the needle point cannot be prevented from being injured by acupuncture, and the infection and the transmission of blood-borne diseases (AIDS, hepatitis B, hepatitis C and the like) are still caused.

After the 21 st century, the need for safe injection of injection needles has become more urgent due to governments and international society of various countries. Safety syringes of various technical solutions are available on the market. Most of the schemes are to use manual hand power or mechanical force (such as a spring) to make the injection needle retract into the outer cylinder or shield the inner cavity of the push rod, and simultaneously destroy the injection needle to make the injection needle not reusable.

However, the cost of the safety syringe is increased by several times compared with the common syringe, which adversely affects the popularization of the safety syringe and limits the application range of the safety syringe. Meanwhile, the existing safety syringe is a technical scheme of protecting the injection needle by using the syringe, so that the risk-free syringe is greatly destroyed, and serious resource waste is caused.

Therefore, there is a need to design a disposable safety syringe with self-protection function for use with an injector and with a minimized cost.

Examples

The specific implementation mode of the utility model is shown in figures 1-3, the disposable safe injection needle comprises a needle base 1 and a needle tube 2, and a needle sleeve 3 is sleeved outside the needle tube 2. Wherein, one end of the needle sleeve 3 close to the needle seat 1 is flexibly connected with a sleeve ring 31 arranged on the needle seat 1. The side wall of the needle sleeve 3 is provided with an opening 35 for moving out the needle base 1 and the needle tube 2. The sleeve ring 31 is connected with the needle sleeve 3 through a detachable connecting piece. In this embodiment, the needle sheath 3 and the sleeve ring 31 are an integrated structure, which can effectively avoid the occurrence of the loss of parts. Meanwhile, the sectional area of the part of the needle sleeve 3, which is positioned on the needle seat 1, is larger than that of the part of the needle sleeve 3, which is positioned on the needle tube 2. The design can facilitate medical care personnel to visually distinguish the positions of the needle base 1 and the needle tube 2 at the first time.

Before the disposable safety injection needle is used, medical staff only need hold the needle sleeve 3 with one hand and then break the sleeve joint ring 31 with the other hand, so that the detachable connecting piece can be separated, and the needle base 1 and the needle tube 2 are moved out from the needle sleeve 3, so that the injection needle can be normally used in cooperation with an injector. After the use, the needle seat 1 and the needle tube 2 are moved into the needle sleeve 3 while the detachable connecting piece is reconnected by reversely snapping the socket ring 31, so that the injection needle, especially the needle tube 2, can be stored in all directions. Specifically, the detachable connecting piece can adopt common buckle type clamping pieces and plug-in type clamping pieces, and is convenient to use and low in cost.

The disposable safety injection needle can take the needle tube 2 into the needle sleeve 3 for storage after use, thereby avoiding the acupuncture risk caused by the exposed needle tube 2 after use and further avoiding the infection and the spread of blood-borne diseases. Wherein, because the disposable safety injection needle connects the needle base 1 with the needle sleeve 3 through the sleeve ring 31, compared with the existing tubular needle sleeve, the possibility that the safety component, namely the needle sleeve 3 is lost can not occur. Simultaneously, compare in the safe injection device that current needs the syringe to participate in, the syringe of this disposable safe syringe needle is accomodate and is need not the participation of syringe, consequently, it still has the advantage that the structure is ingenious, low cost, convenient to use.

In particular, the needle hub 3 is flexibly connected to the coupling ring 31 by a flexible coupling 32. The needle sleeve 3 is flexibly connected with the sleeve ring 31 through the lantern ring connecting piece 32, so that the requirement of breaking off the needle seat 1 installed in the sleeve ring 31 can be met, and the needle tube 2 and the needle seat 1 can be moved out of/into the needle sleeve 3.

In this embodiment, a notch 34 is formed at one end of the needle sleeve 3 away from the needle seat, so that medical staff can observe whether the needle tube 2 is straight or not through the notch 34, thereby avoiding using defective products. Specifically, the notch 34 is a square notch. Of course, other shapes of the notch 34 can be selected during the actual manufacturing process, and are not limited to a square shape.

It should be noted that the detachable connector is a breakable disposable connector 311 for cost saving and medical safety. This is primarily to prevent the disposable safety needle from being recycled by a bad merchant. Meanwhile, in order to further avoid the situation that the needle sleeve 3 is separated from the needle sleeve 3, a needle tube limiting part 33 for limiting the needle tube 2 is further arranged in the needle sleeve 3. The needle tube position limiter 33 in this embodiment includes two spaced position limiting plates arranged in a V-shape. The syringe stop 33 is located below the syringe 2 prior to use. After the needle tube is used, the needle tube 2 can be pressed down to the lower part of the two limit plates, and the needle tube 2 is clamped to prevent the needle tube from falling off and hurting people. Of course, other shapes of the needle cannula stop 33, such as a U-shaped member or a notched plate, may be selected as desired during the actual manufacturing process.

The disposable connectors 311 are two, and the two disposable connectors 311 are disposed on opposite sides of the socket ring 31. The disposable connecting piece 311 designed in this way can ensure that the separation of the needle sheath 3 and the sleeve joint ring 31 can not easily occur before the disposable safety injection needle is used, thereby ensuring the safety of medical personnel. Meanwhile, the disposable connection member 311 is a column shape, and the sectional area of the middle portion thereof is smaller than the sectional areas of both ends thereof. The design is also to ensure that the medical staff can easily break the disposable connecting piece 311, so as to be convenient for use.

The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the above-disclosed embodiments, and various modifications, equivalent combinations, which are made according to the essence of the present invention, should be covered.
