Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a vaccine syringe. Background Art

[0002] In order to reduce infectious diseases or cross-infection, vaccination requires a one-person-one-needle-one-tube system, so disposable syringes are very popular. Vaccines are transported in sealed bottles at low temperatures and then taken out after arriving at the destination. Only then do they need to be injected with disposable syringes. This requires medical workers to complete multiple steps such as taking the vaccine bottle and opening it, taking the syringe, and then extracting the vaccine. This not only increases the workload of medical workers, but also makes it very easy for bacteria to be attached during the vaccine removal operation and the syringe extraction process. At the same time, if the vaccine extraction operation time is too long, the vaccine will be affected by the ambient temperature, causing a small amount of active ingredients to be inactivated, which weakens the vaccine effect, thereby greatly reducing practical performance and other problems.

[0003] In view of this, research and improvement are conducted on the existing problems, and a vaccine syringe is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0007] As a further optimization of the technical solution, the front end of the sleeve of the vaccine syringe of the utility model is conical, the rear end is cylindrical, and the sleeve is made of medical transparent plastic.

[0008] As a further optimization of the technical solution, the limit platform of the vaccine syringe of the utility model is in a circular ring shape, and a needle penetrates the middle position of the limit platform.

[0009] As a further optimization of the technical solution, one end of the compression spring of the vaccine syringe of the utility model is connected to the protective cover, and the other end is tightly connected to the rear end of the syringe.

[0010] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0011] 1. The utility model provides a vaccine syringe, which stores the syringe containing the vaccine in a sleeve and seals it with a sterile packaging bag, thereby reducing the number of operating steps from transportation to injection, preventing bacterial infection, improving the vaccine effect, and further improving the practical performance of the device.

[0012] 2. The utility model provides a vaccine syringe. The syringe can be firmly fixed in the sleeve by passing the needle of the syringe through the limit platform and then applying pressure with the compression spring at the rear end, so as to avoid damage caused by shaking and influence on the vaccine inside, thereby improving the safety performance of the device and making it more practical.

[0013] 3. The utility model improves the structure of the above-mentioned device, simplifies the vaccine transportation and injection operation steps, is not easy to cause bacterial infection, improves the vaccine effect, and further improves the safety performance of use, thereby effectively solving the problems and shortcomings of the existing technology and equipment.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figures 1 to 3 The utility model provides a specific technical implementation scheme of a vaccine syringe:

[0021] A vaccine syringe comprises: a sleeve 1, a limit platform 2, a syringe 3, a needle 4, a protective cover 5, a compression spring 6, and a sterile packaging bag 7; the interior of the front end of the sleeve 1 is an integrated structure with a limit platform 2, and the syringe 3 is placed inside the sleeve 1; the needle 4 is installed at the front end of the syringe 3, and the needle 4 passes through the limit platform 2; the protective cover 5 is screwed to the rear end of the sleeve 1 by threads, and the compression spring 6 is bonded to the inner wall of the protective cover 5; the sleeve 1 is packaged inside the sterile packaging bag 7.

[0022] Specifically, the front end of the sleeve 1 is conical, and the rear end is cylindrical. The sleeve 1 is made of medical transparent plastic, and the sleeve 1 is packaged in a sterile packaging bag 7 to further improve the hygiene and safety performance, and to provide a certain degree of protection for the syringe 3.

[0023] Specifically, the limiting platform 2 is in a circular ring shape, and a needle 4 passes through the middle of the limiting platform 2 .

[0024] Specifically, one end of the compression spring 6 is connected to the protective cover 5, and the other end is tightly connected to the end of the syringe 3, and the force of the compression spring 6 only needs to be sufficient to firmly fix the syringe 3 in the sleeve 1, and the force should not exceed the thrust of the piston of the syringe 3 to avoid leakage of the internal vaccine.

[0025] Specific implementation steps:

[0026] When using the device, first draw one person's dose of vaccine into the syringe 3, then place it into the sleeve 1 and package it in a sterile packaging bag 7 and transport it to the vaccine injection hospital through the cold chain. The staff only needs to open the sterile packaging bag 7 and unscrew the protective cover 5 to take out the syringe 3 and directly perform the vaccine injection. This process is simple and quick, thereby reducing unnecessary trouble and making the device more practical.

[0027] To sum up: this vaccine syringe, by storing the syringe with the vaccine in the sleeve and sealing it with a sterile packaging bag, reduces the operating steps from transportation to injection, eliminates bacterial infection, improves the vaccine effect, and further improves the practical performance of the device; by passing the needle of the syringe through the limit table and applying pressure with the compression spring at the rear end, the syringe can be firmly fixed in the sleeve, avoiding damage caused by shaking and affecting the vaccine inside, thereby improving the safety performance of the device, making it more practical, and solving the problems existing in the prior art.
