The present invention relates to a needle length adjusting device, a needle length adjusting device, a syringe having the same adjustable needle length, and a syringe package.

Vaccines to prevent COVID-19, which is spreading worldwide, are manufactured by various manufacturers and supplied to each country. In order to achieve herd immunity through the above vaccine for preventing COVID-19 as soon as possible, each country is striving to increase the amount of vaccine secured and the inoculation rate, while taking various measures to ensure efficient and safe vaccination without medical accidents at the medical site. are devising a plan.

Since the vaccine for preventing COVID-19 is supplied through various manufacturers, specifically Moderna, AstraZeneca, Pfizer, and Janssen, each vaccine Each has a difference in supply and inoculation methods. For example, the number of inoculations may be different from one or two times for each vaccine. In addition, since each vaccine is stored and supplied in liquid or powder form (used with the addition of a solvent or diluent) in vials with different specifications, the number of people who can be inoculated per vial and the dose per dose may also be different. Accordingly, medical staff are paying attention to the number of inoculations by different vaccine manufacturers, the number of people who can be inoculated per vial, and the inoculation dose, and to ensure that inoculation is performed without medical accidents.

However, even though the number of people who can be inoculated per vial is determined as described above, in the case where the remaining amount of vaccine for 1 or 2 doses remains in the vial in the actual medical field, since the needle length is not adjusted with a commonly used syringe, the rubber of the vial It was difficult to extract the remaining amount because the needle exposed through the front was long. In addition, even if extraction of the remaining amount in the vial is possible, there is a problem in that excessive time is required for vaccine extraction at a medical site where a large number of people are inoculated. In addition, it has been pointed out that it is not appropriate in the current situation where the supply and demand of vaccine is not sufficient in that the remaining amount of about 1-2 doses of the vaccine that has not been extracted is contained in the vial and discarded.

In addition, when the vaccination target for the COVID-19 preventive vaccine is a child under the age of 15, the vaccination dose per dose is inevitably relatively small, about 50 to 90% compared to adults, and adult syringes currently used in medical settings When using as is, it is difficult to accurately control the inoculation amount, so there is a risk of medical accident inoculating an excessive amount of vaccine to children. In addition, in the case of children compared to adults, there is a problem that the risk of inserting a needle of the same length as that of an adult inoculation may occur even though the needle length to be inserted should be short because the skin, subcutaneous fat layer, and deltoid muscle are thin.

Therefore, it is necessary to research and develop a syringe capable of minimizing the remaining amount of vaccine in the vial when inoculating a vaccine for preventing COVID-19 and adjusting the length of the needle inserted during inoculation and the appropriate inoculation amount depending on the inoculation target, such as adults and children. The situation is.
