Problems solved by technology

This device does not guarantee the sterility of the liquid components introduced into the syringe, and the liquid components may become contaminated, especially if they come into contact with the outlet orifice of the cartridge valve.
The device is not suitable for dispensing compressible components (gaseous or containing gas) because it is difficult, if not impossible, to accurately measure the volumetric dose introduced into the syringe simply by observing the position of the plunger

Embodiment Construction

[0052] figure 1 The device 1 of the present invention is shown in a ready-to-use sterile packaged state, comprising:

[0053] A sterile outer package 2 of a sealed airtight enclosure containing the various components of the device is defined, namely:

[0054] a rigid cartridge 3 as a container containing a single-use amount of therapeutic fluid, especially therapeutic gas at a certain pressure;

[0055] Administration syringe 4;

[0056] Filter type sterilization device 5;

[0057] An upstream sealing connection 6 to be placed between the filter sterilization device 5 and the cartridge 3;

[0058] injection needle 7;

[0059] For a bracelet 8 worn by the patient.

[0060] All of these components are single use, disposable.

[0061] The cartridge 3 comprises an external hard metal, especially aluminum or tin-plated iron housing 9, which defines a port closed by an outlet valve 10 with, for example, the commercially available EPSPRAY SYSTEM SA ( Switzerland) produced th...

Abstract

The apparatus for an impromptu preparation of an individual quantity of a sterile fluid has a rigid cartridge (3) containing the fluid. A syringe (4) has a piston sliding within a cylinder, and an axial outflow opening (41). A flushing / sterilizing unit (5,6) is fitted in the flow path between the cartridge and the syringe, to sterilize the fluid by filtration.

Description

technical field [0001] The present invention relates to a device and method for the extemporaneous preparation of single-use quantities of sterile therapeutic fluids which are compressible, in particular a device for administration to a patient (human or animal) therapeutic gas. Background technique [0002] Some therapeutic or surgical procedures require the injection of sterile and compressed fluids, so-called therapeutic fluids, especially gases such as air or fluorocarbon gases (CF 4 、C 2 f 6 、C 3 f 8 ,...), SF 6 , N 2 , CO 2 Etc. For example, some ophthalmic surgery procedures need to locally inject the above-mentioned sterile, completely neutral therapeutic gas into the ocular cavity. [0003] The general problem posed here is therefore that of enabling a professional to obtain single-use quantities (that is to say for a single patient) of the above-mentioned fluids under appropriate conditions for intended injections in a completely sterile state. [0004] To...
