Title:
皮内注射器
Document Type and Number:
Japanese Patent JP3993169
Kind Code:
B2
Abstract:
An injection device that comprises a chamber configured for containing a substance to be injected and a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an intradermal injection site. A collar surrounds the needle, defining a collar cavity. The collar also has a peripheral forward skin-contacting surface that surrounds and is radially spaced from the needle and injection site by an area that is sufficiently large to allow a patient's skin to move into the collar cavity to properly position the needle for intradermal delivery of the substance to the injection site to allow spread of the injected substance under the skin while inhibiting or preventing backpressure within the skin from forcing the substance out through the injection site.
