Abstract

A single-use, needleless injector, comprises a capsule which contains a substance to be injected and has an outlet orifice at the distal end thereof. A power unit which has a pre-loaded power source is assembled to the proximal end of the capsule. When the power source is released it causes the said substance to be expelled from the outlet orifice of the capsule. A sleeve is located on the exterior of the injector and is slidable in a direction towards the distal end of the capsule to cause the power source to be released. A holder is provided for holding and operating at least such injector. The holder comprised a housing and a respective support member for the or each injector, mounted in the housing and arranged to receive the proximal portion of the injector and engage the sleeve thereof.
