FR2733901A1 - Sealed container for used hypodermic syringe and needle - Google Patents

Abstract

The container (1,2) has a foam square in its base to immobilise the needle (4). The container has a lock which can be activated by simple hand pressure. The cover (2) can articulate with the container by a zone of reduced thickness. A catch on the cover can engage in the catch on the container by simple pressure of the hand for locking. A stop (7) can limit forcing of the catch on the cover onto that on the container.

Description

AS
SINGLE USE LOCKABLE BOX for EASY INSULATION and
QUICKLY the CONTAMINATED MATERIAL such as a syringe and its needle.

B - DESCRIPTION 1) Indication of the technical field of the invention
The invention relates to a device which makes it possible to deposit the soiled needle and syringe in a box, without manipulation of the needle with a view to permanently enclosing this matrix in the box by means of a locking system, and thus to evacuate Lt> ut ri.Nilue of contamination for the user and the environment.

2) Indication of the previous technical state highlighting the technical problem posed
Isolating material contaminated with blood still requires manipulations which potentially risk contaminating the user and also leads to a loss of time in work.

The more handling of the soiled material, the greater the risk of contamination.

It is therefore necessary to minimize gestures which allow the user to isolate a contaminated needle + syringe so as to make the isolation circuit (of contaminated equipment) as short as possible. And thus provide the greatest safety and reliability both for the user and for the environment, thanks to simple and quick to use equipment. Indeed, one should not neglect, in practice, the little time which can be allotted to the user to isolate contaminated material (heavy workload but also emergency situation).

3) Presentation of the inventioll
The box allows to isolate soiled material in order to eliminate the risks of contamination, this respecting essential criteria of:
a Security - for the user
- for the environment
b Reliability
c Speed - Ease of use
a Security
- for the user: It is important to do a small ergonomic study, in order to highlight the need to remove certain unnecessary and potentially dangerous gestures:
The box is placed open, next to the user and the patient at the site of use which is easily accessible at the time of injection or of the sample.

The needle adapted to the syringe will be directly inserted into the square of foam at the bottom of the box in order to immobilize the needle + syringe assembly before closing the box: there is no dangerous handling here.

Ergonomic benefits: the needle does not change direction between the end of use and the isolation in the box. It must not at any time be oriented towards the user since the latter will prick the needle into the box placed next to him as soon as the end of use.

The user can close the box by returning the lid to the container, and lock it by simple pressure of the hand.

- for the environment
Soiled material is isolated in the box. This, to avoid accidental reopening has a locking system, which again eliminates other risks of contamination after isolation of the needle.

b Reliability
.11 there is no risk of contamination for the user by closing the box: the needle is immobilized at the bottom of the box.

 The box cannot be used for another syringe: since this material is for single use.

 It cannot be opened after use thanks to its locking system inside the box.

c Speed
The box will be placed before use next to the user in order to eliminate the time and intermediate gestures to isolate the soiled material.

The box closes quickly with the touch of a hand.

This simplicity of use ensures time savings and a certain comfort in the work.

4) Presentation of the different figures
The attached drawings show:
- figure 1 closed box
- figure 2 locking system of the open box
- Figure 3 open box showing all over the
length the locking system and the
foam square layout
- figure 4 - in section - the closed box is locked 5) Detailed presentation with embodiment - Structure and Layout
With reference to these drawings, the device (fig. 1) consists of a box (container (1) and cover (2)) and showing no possibility of closing or opening on the external part of the box.

 The cover (2) is articulated with the container by a zone of reduced thickness (3) of the wall of the box.

At the bottom of the container, a square of adhesive foam (4) is intended to receive the needle. This foam will be sufficiently rigid and resistant to immobilize the needle without risk of perforation of the plastic.

The container has on its internal and longitudinal face two notches (5) which will fit together with the notches of the cover.

Indeed, the cover also has on its internal and longitudinal face two notches (6). The notches of the lid and the container are antagonistic in shape. Each notch has an oblique cut and a horizontal cut. The notches will be able to fit together by sliding and locking one inside the other.

The locking system also reveals a safety stop (7) which limits the sinking of the notches of the cover into those of the container and eliminates the risks of poor closing due to excessive pressure from the hand of the user.

By way of nonlimiting example, the box will have dimensions of the order of
- 4 cm for the width
- 15 cm for the length 6) Indication of how the invention is capable of industrial application
The device according to the invention is essentially intended to isolate needles and syringes soiled with blood. It will be made of rigid plastic.

However, we can consider any other application of this system in other areas of activity: to isolate equipment or waste that can injure or pollute and thus provide greater protection.

Claims (4)

C - CLAIMS 1) Device for isolating contaminated material such as a syringe provided with a needle characterized in that it comprises a housing (1) and (2), having at the bottom of the container a square of foam intended to immobilize the needle (4) , and provided with a locking system inside the box (5 and 6) by simple pressure of the hand. 2) Device according to claim 1 characterized in that the cover (2) can be articulated with the container by an area of reduced thickness allowing the articulation (3). 3) Device according to claim 1 characterized in that the notches of the cover (6) fit into the notches of the container (5) by simple hand pressure to ensure final locking and without any possibility of reopening the box. 4) Device according to claim 1 characterized in that the stop (7) limits the depression of the notches of the cover in those of the container and thus eliminates the risk of poor closure.
