Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a sharps separation device for vaccine vaccination. Background Art

[0002] Vaccination is the technology of inoculating vaccine preparations into human or animal bodies, so that the recipient can gain immunity against a specific pathogen or a pathogen similar to the vaccine. Through the recognition of foreign substances by the immune system, antibodies are screened and manufactured to produce antibodies against the pathogen or similar pathogens, thereby making the recipient more resistant to the disease. The most common method of vaccination in medicine today is injection, and the word "vaccination" comes from the smallpox vaccination technology. Its original meaning is different from today's usage, and there is also a slight difference in the scope of application in modern immunology research.

[0003] Therefore, a large number of syringes are generated every day. Most of these syringes are disposable medical supplies. The traditional treatment solution is to discard the syringes directly. However, as a sharp instrument, if the needle is not separated properly, there is a risk of puncturing the staff, and even causing cross infection. In my country, each person receives an average of 4.18 injections per year. It has been found that pathogens that can be infected through needle stick injuries include: hepatitis B, hepatitis C, hepatitis G, HIV, herpes simplex, herpes zoster, Ebola / Marburg, dengue fever, Creutzfeldt-Jakob disease, Brucella abortus, Corynebacterium diphtheriae, Neisseria gonorrhoeae, Leptospira hemorrhagic jaundice, Staphylococcus aureus, Streptococcus pyogenes, Mycobacterium tuberculosis, etc., which threaten the health of medical staff.

[0004] In addition, prefilled syringes are often used in current vaccinations. The needle and syringe of such syringes are integrated, not separated. In actual use, such prefilled syringes also need to be separated for later processing.

[0005] Therefore, there is an urgent need to design a sharps separation device for vaccine vaccination, which can separate the separable syringes and the prefilled syringes for easy storage and processing. Utility Model Content

[0010] Two separation mechanisms are arranged on the existing sharps separation device, which can respectively perform different separation operations on the detachable needle, syringe and the syringe with the integrated needle and syringe. The operation is simple and convenient, and different types of syringes can be quickly separated. At the same time, the hands of medical staff also need to touch the needle and other sharp objects to prevent scratches and infection, which greatly improves the work efficiency and facilitates the later recycling and processing.

The track is opened in the base, the limiting structure is arranged in the track, and the separation structure is symmetrically hinged in the track and adapted to the limiting structure.

[0015] Preferably, a support and limiting structure is provided at the hinged part on the lower side of the separation structure of the sharps separation mechanism 1, and the end of the separation structure is an arc-shaped structure.

[0023] (2) The utility model designs a sharps separation mechanism, which is composed of a track, a limiting structure, and a separation structure. The limiting structure limits the syringe to a suitable position so that the separation structure is placed just between the needle part and the syringe tube of the syringe. Then, the operator only needs to pull the syringe tube upward to separate the needle and the syringe tube. The needle can fall into the collection bucket through the track due to gravity.

[0024] (3) The utility model designs a sharps separation mechanism II, which is composed of a cutting structure and a breaking structure. By inserting the needle end of the syringe into the cutting structure, the front end of the needle tube of the prefilled syringe near the bottom end of the needle can be cut. After the cutting is completed, the prefilled syringe is inserted into the breaking structure, and then a reverse force is applied to the breaking structure, so that the prefilled syringe can be broken from the cut portion, completing the separation of the sharp part of the prefilled syringe, and the sharp part falls into the collection bucket under the action of gravity.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] Embodiment 1:

[0037] See attached Figure 1 As shown, a sharps separation device for vaccine vaccination comprises a shell 1, a collecting barrel 2 is arranged in the shell 1, a door panel 101 is hinged at the lower end of the shell 1 for easy access of the collecting barrel 2, the collecting status of the collecting barrel 2 can be checked at any time through the door panel 101, and the collecting barrel 2 can be replaced in time, and the collecting barrel 2 has two collecting chambers, namely a sharps collecting chamber and a consumables collecting chamber, the sharps collecting chamber is used to collect the needle part of the syringe, and the consumables collecting chamber is used to collect the needle tube and other components of the syringe;

[0038] See attached Figure 2-3 As shown, a sharps separation base 3 adapted to the collection barrel 2 is fixedly arranged on the upper end of the housing 1, and a sharps separation mechanism 1 301 and a sharps separation mechanism 2 302 are provided in the sharps separation base 3. The sharps separation mechanism 1 301 is used for syringes with detachable needles and needle tubes.

[0039] Specific reference attached Figure 4-5 As shown, the sharps separation mechanism 301 includes a track 301-4, a limiting structure 301-1, and a separation structure 301-2; the track 301-4 is preferably a cylindrical structure and is opened in the base 3, the limiting structure 301-1 is arranged in the track 301-4, and the separation structure 301-2 is symmetrically hingedly arranged in the track 301-4, and it can only rotate between 0-90 degrees, and the separation structure 301-2 is adapted to the limiting structure 301-1, so as to separate the needle part and the needle tube part of the syringe;

[0040] See attached Figure 6 As shown, the limiting structure 301-1 is a circular structure, and a through hole 301-1A is provided in the middle, and the through hole 301-1A is adapted to the syringe needle tube, that is, the needle part of the through hole 301-1A can pass through, and the syringe part cannot pass through, that is, the diameter of the syringe is larger than the diameter of the through hole 301-1A;

[0041] Further references Figure 5 , 7 As shown, a support and limiting structure 301-3 is provided at the hinged part of the lower side of the separation structure 301-2, and the end of the separation structure 301-2 is an arc-shaped structure. The arrangement of the arc-shaped structure facilitates the separation structure 301-2 to be compatible with the needle and the syringe of the syringe (the existing syringes are generally circular structures); the support and limiting structure 301-3 allows the two separation structures 301-2 to be arranged oppositely, and the maximum distance between the two separation structures 301-2 is less than the diameter of the connection between the syringe needle end and the needle;

[0042] The two separation structures 301-2 are arranged relative to each other using the support and limit structure 301-3, so that syringes of different thicknesses can pass through the two separation structures 301-2. The two separation structures 301-2 are always against the syringe, and when the syringe is pulled upward, the support and limit structure 301-3 can block the needle part of the syringe, so that the needle can be separated from the syringe when the syringe is pulled up, completing the sharp separation operation of the syringe;

[0043] Specific reference attached Figure 5As shown, the support and limiting structure 301-3 includes an elastic member 301-3A and a limiting member 301-3B, one end of the elastic member 301-3A and the limiting member 301-3B are respectively fixedly connected to the side wall of the track 301-4, and the other end is respectively fixedly connected to the separation structure 301-2; the elastic member 301-3A is preferably a spring, which supports the hinged separation structure 301-2 so that it is always in a state perpendicular to the side wall of the track 301-4, and the limiting member 301-3B is preferably an inelastic soft belt, which limits the separation structure 301-2, and when the syringe needle is pulled up, it further enhances the downward pulling force of the separation structure 301-2, so that the syringe needle and the syringe are separated;

[0044] The use process and principle of the sharps separation device for vaccine vaccination in the preferred embodiment are as follows: first, insert the detachable syringe into the track 301-4 from one end of the needle, then pass one end of the syringe needle through the perforation 301-1A of the limiting structure 301-1, and then pass through between the two separation structures 301-2, and at the same time squeeze the two separation structures 301-2, so that the elastic member 301-3A is compressed, and the limiting member 301-3B is squeezed and folded due to its flexibility. At the same time, since the diameter of the syringe barrel is larger than the diameter of the perforation 301-1A, the bottom of the syringe barrel finally abuts against the limiting structure 301-1A. At the upper end of structure 301-1, the tail of the needle of the syringe just passes through the two separation structures 301-2, and then the syringe is pulled upward. At this time, the tail of the needle of the syringe is stuck between the two separation structures 301-2. When the pulling force continues to be applied, under the action of the hinge and the pulling force of the limit member 301-3B, the tail of the needle of the syringe is stuck on the lower side of the two separation structures 301-2. Under the action of continuous pulling force, the needle part is separated from the needle tube part, and under the action of gravity, the needle part falls into the collection bucket 2 through the track 301-4, thereby completing the sharp separation and collection of the syringe.

[0045] Example 2

[0046] See attached Figure 4 As shown, the difference between Example 1 and Example 2 is that, on the basis of Example 1, a sharp separation mechanism 2 302 is further provided on the separation base 3, for separating and collecting the sharps of the prefilled syringe; specifically, the sharp separation mechanism 2 302 includes a cutting structure 302-1 and a breaking structure 302-2, which are sequentially provided in the separation base 3, and by inserting the syringe needle end into the cutting structure 302-1, the front end of the needle tube of the prefilled syringe near the bottom end of the needle can be cut, and after the cutting is completed, the prefilled syringe is inserted into the breaking structure 302-2, and then a reverse force is applied thereto, so that the prefilled syringe can be broken from the cut portion, completing the separation of the sharp part of the prefilled syringe, and the sharp part falls into the collection bucket under the action of gravity;

[0047] See attached Figure 5 , 8 As shown, the structure of the cutting structure 302-1 is the same as that of the sharps separation mechanism 301, both of which include a track 301-4, a limiting structure 301-1, and a separation structure 301-2; the track 301-4 is preferably a cylindrical structure, and is opened in the base 3, the limiting structure 301-1 is rotatably arranged in the track 301-4, and can rotate 360 ​​degrees relative to the track 301-4, the separation structure 301-2 is symmetrically hingedly arranged in the track 301-4, and can only rotate between 0-90 degrees, and the separation structure 301-2 is adapted to the limiting structure 301-1, so as to separate the needle part and the needle tube part of the syringe;

[0048] See attached Figure 6 As shown, the limiting structure 301-1 is a circular structure, and a through hole 301-1A is arranged in the middle, and the through hole 301-1A is adapted to the syringe needle tube, that is, the needle head part of the through hole 301-1A can pass through, and the syringe part cannot pass through, that is, the diameter of the syringe is larger than the diameter of the through hole 301-1A; and a plurality of rubber protrusions 301-1B are also arranged on the upper surface of the limiting structure 301-1, which are used to increase the friction force when it contacts the syringe;

[0049] The difference is that, refer to the Figure 8 As shown, an elastic support member 302-1A is provided at the hinge of the separation structure 301-2, which is used to support the separation structure 301-2 and enable the separation structure 301-2 to adapt to syringes of different specifications, and at the same time, its end is against the syringe; and a cutting blade is provided at the end of the separation structure 301-2, which can cut the glass wall of the prefilled syringe;

[0050] See attached Fig. 9 As shown, the breaking structure 302-2 is a breaking channel opened in the base 3, and the breaking channel includes a vertical track 302-2A and an arc track 302-2B connected to each other. The setting of the arc track 302-2B facilitates the breaking of the cutting part of the prefilled syringe, so that the needle and the needle tube of the prefilled syringe are better separated;

[0051] The use process and principle of the sharps separation device for vaccine vaccination in the preferred embodiment are as follows: first, insert the prefilled syringe (or an integrated syringe) into the track 301-4 from one end of the needle, then pass one end of the syringe needle through the perforation 301-1A of the limiting structure 301-1, and then pass through between the two separation structures 301-2, and at the same time squeeze the two separation structures 301-2, so that the elastic support member 302-1A is compressed, and at the same time, because the diameter of the syringe barrel is larger than the diameter of the perforation 301-1A, the bottom of the syringe barrel finally abuts against the upper end of the limiting structure 301-1, and the injection is now The tail of the needle of the syringe also just passes through between the two separation structures 301-2, and the two separation structures 301-2 are against the bottom of the syringe barrel, and then the syringe is rotated. At this time, it rotates synchronously with the limiting structure 301-1 driven by the syringe. At the same time, the blade parts of the two separation structures 301-2 cut the bottom of the syringe barrel of the syringe. After rotating several circles, take out the cut syringe, insert it into the breaking structure 302-2, and then give it a reverse force. The syringe will be disconnected from the cutting part, and its sharp part will immediately fall into the collection bucket 2, completing the sharp separation and recycling of the prefilled syringe.
