Triggering means for a pressure jet injector
First Claim
1. A pressure jet injector for administering an injectable product, said pressure jet injector comprising:
- a) a casing;
b) a feeder mounted on the casing;
c) a pressure chamber from which the product is administered by a feeding action of the feeder, the product exiting through a jet outlet of the pressure jet injector;
d) a trigger for triggering the feeder; and
e) a resistance element supported by the casing, wherein a pressing force, with which the jet outlet is pressed against a tissue for an administration of the product, is exerted on the trigger and is transferred from the trigger to the resistance element and from the resistance element to the casing, the feeder being triggered as the pressing force reaches or exceeds a selected magnitude.

Abstract
A pressure jet injector for administering an injectable product, including a casing, a pressure chamber connected to the casing, and a feeder for administering the product from the pressure chamber. To administer the product, a jet outlet, which may be formed as the pressure chamber outlet, is pressed against tissue using a pressing force. The pressing force acts on a trigger for the injector. The trigger is connected to the casing such that the pressing force is transferred to a resistance element. The resistance element is supported on the casing and the pressing force acting on the trigger is further transferred from the trigger onto the casing via the resistance element. The feeder is triggered as the pressing force reaches or exceeds a pre-set and/or measured magnitude.

23. A pressure jet injector for administering an injectable product, said pressure jet injector comprising:
-
a) a casing;
b) a pressure chamber connected to the casing from which the product is administered, the pressure chamber having a pressure chamber outlet at a front end;
c) a feeder for administering the product from the pressure chamber; and
d) a trigger for triggering the feeder to administer the product, wherein the pressure chamber outlet is pressed against a tissue with a pressing force, the pressing force being exerted upon the trigger and transferred to the casing via a resistance element, the feeder being triggered as the pressing force reaches or exceeds a selected magnitude. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
