Problems solved by technology

The disadvantage of these types of liquid formulation delivery is that the user must have a large existing supply of liquid formulation to treat a large number of patients or animals
This reduces the practicality and use of the syringe in many settings

Embodiment Construction

[0035] refer to Figure 1 to Figure 5 , a handheld spring-actuated needle-free injector device 10 comprising an inner housing 12 having a front end 14 and a rear end 16 . The front end 14 of the inner housing 12 is constructed and arranged to receive a vial 18 for holding a fluid 20 to be delivered into the tissue of the animal or human 24 through the skin 22 covering the tissue of the animal or human 24 . It should be appreciated that although the present invention has been described in relation to "skin" and "animal", it is intended to include human, animal and other surfaces.

[0036] Such as figure 1 and image 3 As shown, the inner shell 12 is movably mounted within the outer shell 28 for sliding movement along its axial direction. The inner shell can be obtained from Figure 4 The wait position shown moves to the Figure 5 The trigger position is shown.

[0037] The inner shell 12 can be moved to the Figure 4 waiting position. The skin tensioning spring 30 has at ...

Abstract

A vial filling system for a needle-less injector, the system including an adaptor (70). The adaptor (70) has a housing including a top and a side wall extending downwardly from the top. A recess (72) is disposed in the side wall of the adaptor for receiving a vial. The vial (18) has an inner cavity for receiving a liquid formulation. An inlet opening (80) is located in the top of the adaptor, wherein when the vial is inserted into the recess the inlet opening is aligned with a nozzle of the vial. A needle (82) extends from the top of the housing and in communication with the inlet opening. The needle is constructed and arranged to pierce a container of liquid formulation. A plunger (38) is movably disposed within the cavity of vial for drawing the liquid formulation from the container into the cavity of the vial.

Description

technical field [0001] The present invention relates to vial filling systems and methods for filling vials of needle-free injectors for the subcutaneous delivery of doses of liquid formulations to humans or animals, and more particularly to A filling adapter for a vial of a needle-free injection device that delivers a high-pressure fluid jet through the epidermis of a human or animal. Background technique [0002] The advantages of needle-free injection devices have been recognized for some time. Some of these advantages include: the absence of dangerous needlestick injuries to health care workers; reduced risk of cross-infection between humans or animals; elimination of the risk of needle breakage in human or animal tissue; The jet is usually smaller than the diameter of a hypodermic needle, so it is less painful than a hypodermic needle. [0003] Due to the known advantages of needle-free injection, there are many pneumatic or pneumatic needle-free injection devices desi...
