Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a disposable safety syringe needle.

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, the self-destruction syringes are often produced in international society by means of a method of stopping the syringe outer cylinder and the plunger, or piercing the piston, or breaking the plunger, etc., thereby limiting the reuse of the syringe. 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 adopts the technical scheme that the syringe is used for protecting the injection needle, 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 a syringe and reducing the cost as much as possible.

Examples

The specific implementation mode of the utility model is shown in figures 1-4, which is a disposable safety injection needle, comprising a needle base 1 and a needle tube 2, wherein the needle tube 2 is externally sleeved with a needle sleeve 3. Wherein, one end of the needle sleeve 3 close to the needle base 1 is flexibly connected with a sleeve ring 31 arranged on the needle base 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, and the needle sleeve 3 is also flexibly connected with a tube cover 4 which is used for shielding the opening 35 and is matched with the opening 35 in a quick-release manner. In this embodiment, the needle sheath 3, the sleeve ring 31 and the tube cover 4 are integrated, so as to effectively avoid the occurrence of the loss of parts.

Before the disposable safety injection needle is used, the needle seat 1 and the needle tube 2 can be moved out of the needle sleeve 3 only by opening the tube cover 4 and then breaking the sleeve joint ring 31, and the injection needle can be normally used in cooperation with the injection syringe. After the use is finished, the needle seat 1 and the needle tube 2 are moved into the needle sleeve 3 only by reversely breaking the sleeve connecting ring 31, and then the tube cover 4 is covered, so that the all-dimensional storage of the injection needle, especially the needle tube 2 can be finished.

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 of losing safety components, namely the needle sleeve 3 and the tube cover 4, can not occur. Meanwhile, compared with the existing safe injection device needing the participation of the injector, the needle tube 2 of the disposable safe injection needle is stored without the participation of the injector, so that the disposable safe injection needle also has the advantages of ingenious structure, low cost and convenient 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. Meanwhile, the needle sleeve 3 is flexibly connected with the tube cover 4 through a bendable tube cover connecting piece 43. The needle sleeve 3 is flexibly connected with the tube cover 4 by the tube cover connecting piece 43, so that the possibility of losing the tube cover 4 can be avoided, and the function of opening/shielding the opening 35 can be achieved.

In this embodiment, there are at least two tube cap connectors 43, and the two tube cap connectors 43 are sequentially arranged along the extending direction of the needle tube 2. The arrangement can ensure the connection stability of the tube cover 4 and the needle sleeve 3, and can limit the track of the tube cover 4 in the overturning process, thereby ensuring the on/off matching of the tube cover 4 and the opening 35.

Meanwhile, the edge shape of the tube cover 4 is matched with the edge shape of the opening 35, so that the integrity of the whole structure can be ensured, and the appearance is attractive. In this embodiment, the edge of the opening 35 is provided with a tube cover clamping step 34 along the edge, and the edge of the tube cover 4 is provided with a cover clamping edge 41 which is in quick-release clamping fit with the tube cover clamping step 34. The tube cover clamping step 34 and the cover clamping edge 41 are in clamping fit, so that the tube cover 4 can be conveniently opened/closed, and the disposable safety injection needle is convenient to use.

In the needle hub 3, a needle stopper 33 for stopping the needle tube 2 is provided. The needle tube position-limiting members 33 include two spaced position-limiting plates arranged in a V-shape. Before use, the needle tube limiting part 33 can effectively support the needle tube 2 to prevent the needle tube 2 from contacting with the inner wall of the needle sleeve 3, so that deformation is generated. After the needle tube is used, the needle tube 2 can be pressed down to the lower parts of the two limiting 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.

In addition, an opening projection 42 for breaking the tube cover 4 and the needle hub 3 is further provided on the outer side wall of the tube cover 4. By opening the projection 42, the medical staff can complete the opening/closing between the tube cover 4 and the needle sheath 3 very conveniently.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made according to the essence of the present invention.
