FR2608053A1 - Safety system for separation/collection of injection and withdrawal equipment for human, veterinary and biological use - Google Patents

Abstract

The invention relates to a single-use box for separating and collecting injection and withdrawal equipment for human, veterinary or biological use, in particular for separating the needle-syringe or needle-withdrawal device system. The box according to the invention is more particularly characterised in that it comprises a neck and a piece E fixed to the upper part of this neck, the said piece E being provided with an orifice A including a slot C emerging at the orifice A, the width of the slot C being such that, on the one hand, it allows the upper part of a needle inserted into the said slot C to be blocked during the separation operation, and on the other hand, it allows the needle to fall into the collection receptacle D after the separation operation.

Description

MATERIAL COLLECTION SECURITY SYSTEM
INJECTION AND SAMPLING FOR HUMAN AND VETERINARY USE
AND ORGANIC
Technical field auauel relates to the invention
Staff handling injection or sampling equipment (needles, trocars, etc.) are frequently victims of accidents; these accidents are all the more serious as the injection or sampling equipment is septic, risking transmitting viral hepatitis B, AIDS, local or general infections with common germs, etc. Our system is intended for all personnel working in human, veterinary or laboratory clinic having to handle needles, trocars or other injection or sampling systems, and seeks to prevent injections, reduce the risk of contamination of these personnel due to the handling of these materials.

State of the prior art
Currently doctors, biologists, veterinarians, nurses handle with high risk of injection different injection and sampling equipment. About 80 percent of nurses' septic injuries are related to recapucination of needles. Needle-syringe or needle-collection device separation is also not without risk since the junction is often soiled or at least septic.

Currently, in the majority of health centers and laboratories, staff proceed as follows after an injection or a sample
- recapping of the needle,
- separation of the recapped cap from the syringe (or the sampling device),
- deposit of the recapped needle in a box which will join a specialized destruction chain; it should be noted that these boxes have a wide opening, which implies a significant septic risk for those around them.

 Sometimes the needle is thrown into these boxes without having been recapped: this nevertheless involves dangerous handling during dissociation.

 These manipulations are all skeptical and numerous scientific publications attest to their danger.

Technical solution aPortée, description of the diagrams
Our system solves both the problem of the immediate fate of the needle, in the absence of manipulation, and its collection in a container specially provided for this purpose.

 Figures 1 and 2 below illustrate, by way of nonlimiting examples, two embodiments of the invention.

 The system is carried on the agent's tray or cart. It should be noted that its small opening does not involve any septic risk, unlike the usual boxes. Once the sample has been taken, the agent introduces the needle or the trocar into the round or oval orifice (A) of the piece (E) of hard plastic at the top of the system (the orifice (A) has a diameter between 10 and 20 mm).

 1-) If it is a needle mounted on a syringe: the upper end of the mounted needle passes below the part (E): it is made to abut against the two angles (B): a simple pull up allows separation of the syringe: the needle falls into the collection jar (D). We do the same with catheters, needles mounted on tubing, lumbar puncture trocars etc ...

2 *) In the case of a screw sampling device ("Vacutainer" type): the mounted needle is inserted into the round orifice (A); the part of the needle closest to the plastic device, of square section, is inserted into the slot (C) whose width corresponds to this section (about 4 mm); once the needle thus blocked, its support is unscrewed; at the end of unscrewing, the "VacutainerZ" type needle is pushed back into the orifice (A) and falls (the length of the slit (C) is less than or equal to 10 mm).
- the needle will never have been left "raw", apart from the obligatory path between the exit of the organism or the material to be sampled and the system; this path can be very short since the small opening of the system allows it to be positioned next to the patient, the septic risk being zero, even in the event of the system falling.

- the needle and its tip have never been touched by the agent; the needle falls directly into the collection jar (D). The needle holder is discarded or retrieved; the system, once full, joins the specialized destruction chain. It should be noted that the system
- in its part (D) is made of translucent plastic (visualization of the filling level), flexible but resistant to possible crushing; this part (D) has the shape of a cube, ideally from 10 to 20 cm on the side.

 - is for single use: once full, it is discarded: nothing is recoverable: this prevents the part (E) from being exposed for too long.

Mode of carrying out the invention
The industrial production of the system poses no technical problem. An industrial possibility is to realize
- the "container" part, made of plastic, by the usual blowing or other methods,
- the part (E) by stamping or by molding and to assemble the two.

 There seem to be other, even simpler methods, which are all common practice anyway.
