Embodiment 1

[0079] Embodiment 1, the preparation of needle-free injection ampoule

[0080] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0081] Such as figure 1 A. figure 1 As shown in B, the needle-free injection ampoule of prepacked vaccine or medicine provided by the present invention includes a tube body 1, a needle-free syringe joint 2, a power push rod 3, a jetting port 4, a stop rod 5, A sealing cap 6 and a sealing lock block 7; wherein, the tube body 1 is used for pre-filling a fixed and precise dose of vaccine or medicine, the needle-free syringe connector 2 is integrally arranged at one end of the tube body 1, and the power push rod 3 is controlled by the tube body The other end of 1 is slidingly arranged in the tube body 1, and closes the tube body 1; the injection port 4 is set in the needleless syringe joint 2, which has a stop groove 8, and the injection port 4 passes through the stop slot 8 and the...

Embodiment 2

[0092] Embodiment 2, needle-free porcine virus vaccine system and application

[0093] The needle-free porcine virus vaccine system of the present embodiment includes a needle-free injection ampoule filled with 1 / 5-1 times the standard dose of porcine virus vaccine and a needle-free syringe for supporting use;

[0094] The standard dose of porcine virus vaccine is the intramuscular injection dose of 1 part of porcine virus vaccine; the intramuscular injection dose of 1 part of porcine virus vaccine is reflected by the virus content:

[0095] For different porcine virus vaccines, the volume and virus content of 1 porcine virus vaccine intramuscular injection dose are different, as follows:

[0096] Porcine Reproductive and Respiratory Syndrome virus content in 1 portion of porcine virus vaccine should be ≥ 10 5.0 TCID50 / head, the volume is generally 2.0ml per pig.

[0097] The antigen content of the attenuated strain of CSF in 1 pig virus vaccine contains 15,000 RID of virus ...

Abstract

The invention discloses a pig virus vaccine needle-free injection system and application. The pig virus vaccine needle-free injection system comprises a container filled with a pig virus vaccine and a readable carrier. Content recorded in the readable carrier includes that needle-free injection dosage of the pig virus vaccine is not larger than the standard dosage of the pig virus vaccine. Experiments prove that when a needle-free injection ampoule and a needle-free syringe are combined for immunization, the antigen dosage only accounts for part of a traditional intramuscular injection antigen dosage, and the same or better immunization effect can be achieved. It is further indicated that a needle-free immune mode is an ideal strategy capable of being selected by the pig virus immunization vaccine.

Description

technical field [0001] The invention relates to the field of medicine, especially the field of infectious diseases. More specifically, it relates to a needle-free porcine viral vaccine system and application. It is suitable for immunization and vaccination of various porcine virus vaccines. Background technique [0002] Traditional injection techniques require special injection skills and skillful techniques to operate, which requires professionals, which increases labor costs, increases the risk of bleeding and infection when the needle penetrates the animal body, and is prone to the hidden danger of needle breakage in the animal body, which affects Meat is safe to eat. In recent years, needle-free injection technology is in a stage of rapid development. The traditional high-pressure needle-free injection has a large trauma, and today's low-pressure needle-free injection has a small trauma, which promotes the development and application of needle-free injection technology...
