TWI765785B - Preloadable syringe auto-inducer and rechargeable syringe preloaded with same - Google Patents

Abstract

The invention relates to a syringe inducer, which includes a capsule body filled with medicament contents and a puncture member mounted within the capsule body. Alternatively, the syringe inducer may include an outer brace, in which a capsule body and a puncture member are mounted, with the puncture member being mounted outside of the capsule body. The syringe inducer may be preloaded in the barrel of an injection syringe, so that an injection procedure can be carried out by forward compression of a plunger against the capsule body or the outer brace, thereby making the puncture member penetrate the capsule body to release the contents into the syringe barrel. The invention constitutes a substitution for the conventional medication bottles by virtue of the advantages of high portability and high endurance for long distance transport. The invention further relates to a rechargeable syringe preloaded with the syringe inducer.

Description

Self-draining pre-loaded capsules and reloadable capsule injection device
