Description

Injection device for storage

The invention relates to an injection device for storage, which is used for directly injecting stored samples.

With the advancement and development of biotechnology, in many cases it is necessary to preserve biological samples by cryogenic freezing. For some rare and precious samples or drugs, in practice, they are often subpackaged through a plurality of cryogenic tubes or containers. Used for multiple trials or injections, such as vaccines.

Traditionally, when injecting samples or medicines, the biological samples or medicines are thawed first, and then extracted with a needle.

However, some biological samples or drugs may be non-homogeneous or thick due to changes in concentration, crystallization, solubility, or volume during the thawing process, resulting in difficulties in needle extraction operations, or partial The sample is more difficult to extract, and if it is extracted with high pressure, it will cause biological samples or drugs to lose their biological activity, such as stem cell samples.

If the object of operation or injection is a human or live animal, it is difficult to extract biological samples or medicines, which will increase the difficulty for the operator to extract samples; for the operator, it will increase discomfort and injection time.

In addition, if samples or medicines need to be injected, the current practice is to extract them from frozen biological tubes and then inject them into the actual phase, which is inconvenient.

Therefore, the current biological samples or medicines used for injection lack a device that is simple in design, easy to operate, and can maintain biological activity. This invention is designed for the biological sample preservation device used for injection.

In view of the above-mentioned shortcomings of existing storage devices for injection, this creation hopes to allow operators to extract and inject biological samples or drugs without worrying about the difficulty in extracting and injecting samples with heterogeneous phases and high viscosity. In addition, It is more hoped that this creation can combine the device for cryopreservation and the injection device, so as to optimize the operation convenience of the operator or the injection person.
