Description

Title: Device for shielding the free end of a hypodermic needle
The present invention relates to a device for shielding, in particular after use, the free end of a hypodermic needle secured to a hypodermic syringe, which shielding device comprises a shielding part which can at least partly surround the hypodermic needle, and which is slidable in the longitudinal direction of the hypodermic needle by means of control means connected with the hypodermic syringe, the control means being foldable by a hinge joint between a position in which the component parts of the control means make an angle with each other and a substantially stretched position in which the control means are formed by a first connecting element hingedly connected with the hypodermic syringe and a second connecting element hingedly connected with the first connecting element, at the end of which second connecting element the shielding part is provided, at least one of the connecting elements, preferably the second, being relatively rigid.
The intent of such a shield for the free tip of a hypodermic needle after use is to minimize the risk of injuring and infecting those who administer the injection or third parties who afterwards, often by accident, come into contact with the hypodermic needle. The control means should be such that shielding is rendered possible by a simple operation. Although various proposals have been made for such a shield for a needle tip, the control means used therein have still been found too complicated and the production cost thereof is still too high.
A device as described in the opening paragraph is, for instance, known from US-A-5 , 700 , 249. In the two connecting elements referred to therein, no energy is built up during the upward movement of the connecting elements, so that the connecting elements do not move downwards by themselves. At the end of the second connecting element, a complicated shielding part is hingedly provided which, after the connecting elements have been moved upwards far enough, shields the needle tip by a tilting movement.
The object of the invention is to provide a device for shielding the free end of a hypodermic needle as described in the opening paragraph, in which the control means are of very simple design, easy to operate and cheap to produce, while the reliability of the shield is ensured.
According to the invention, the device for shielding, in particular after use, the free end of a hypodermic needle secured to a hypodermic syringe is characterized in that the shielding part is formed by the end of the second connecting element without forming a hinge joint therewith.
In particular with hypodermic needles intended for single use, it is economically favorable if the two connecting elements together with the shielding part are made of plastic and are composed by molding them from one piece. In particular, it is favorable if, furthermore, a securing element is provided by means of which the control means are hingedly connected with the hypodermic syringe, the control means and the securing element being made by molding from one piece .
In order to achieve that in the substantially stretched position the connecting elements tend to move into the folded position, so that the shielding part remains in position against the needle tip, the first connecting element may have a curved shape, and moreover, when the connecting elements have been brought into the substantially stretched position, it may be prestressed. It is also possible that in this substantially stretched position a prestress is built up in the hinge joint between the two connecting elements. Furthermore, in the substantially stretched position, too, a prestress may be built up in both connecting elements. In a further preferred embodiment, the shielding part is of such a shape that it falls over the tip of the hypodermic needle when the control means are brought into the substantially stretched position.
When the control means have been brought into the substantially stretched position, the prestress then present between the two connecting elements and/or the prestress then present between the control means and the securing part and/or the prestress then present in the first connecting element may be such that the shielding part undergoes such a sideward movement with respect to the hypodermic needle that under a simultaneous, backwardly directed movement of the first connecting element effected by at least one of the above prestresses, the shielding part falls over the tip of the hypodermic needle.
The invention will now be explained in more detail on the basis of the accompanying drawing, in which:
Figs. 1A, IB show a first embodiment of the device according to the invention in the folded position and in the position in which the needle tip is shielded, respectively; Fig. 1C is a side view of the second connecting element;
Figs. 2A, 2B show a second embodiment in the above positions ;
In the figures corresponding parts are indicated by equal reference numerals.
Figs. 1A, IB show a syringe head 1 having a hypodermic needle 2 fixed therein. Arranged on and over this assembly of head 1 and needle 2 is a shielding device 3 according to the invention. The shielding device 3 is composed of a shielding part 4, control means 5 and, in the embodiment of Figs. 2A, 2B, also a securing element 6. The control means 5 are built up from a first connecting element 7 and a second connecting element 8.
In the embodiment shown in Figs. 1A, IB, the first connecting element 7 is slightly curved and is prestressed in this curved position. In this embodiment, the shielding part 4 is formed by the bent end of the connecting element 8 and is thereby easier and cheaper to produce. The connecting element 8 is provided with a slot -shaped opening 9 (see Fig. 2C) , thus enabling this element to be moved backwards and forwards in the longitudinal direction over the needle 2 with ample play. Because of the prestress in the curved connecting element 7, the needle 2, when the connecting element is moved upwards in the drawing, will finally slip from the opening 9 and the bent shielding part 4 will come to lie around the needle tip, so that this shielding part cannot be pulled down anymore. As an extra protection, a thickening 10 is provided on the connecting element 8 above the opening 9. This thickening prevents the needle from slipping back into the opening in case the connecting elements should be pressed against it. This embodiment renders it possible that in the event of a sleeve-shaped covering or packing being slid over the whole needle and syringe head, the connecting elements can easily be pressed flat against the syringe head in the position shown in Fig. 2A, while they directly assume the position shown in Fig. 2A when this covering or packing is removed .
In the second embodiment shown in Figs. 2A, 2B, which is largely similar in structure to the first embodiment, a prestress is applied in the hinge points A and B between the two connecting elements 7 and 8 and between the connecting element 7 and the securing element 6. The hinge connections are formed by deformable, thinned connecting parts. The operation is further essentially equal to that of the embodiment in Figs. 1A and IB. In the position shown in Fig. 2B, the condition is reached in which because of the prestresses in the hinge points A and B the shielding part 4 is pushed slightly sidewards (in the direction of the arrow S) , after which the shielding part 4 is pulled over the needle tip (in the direction of the arrow T) .
The shielding part 4, the two connecting elements 7 and 8 and the securing element present in the embodiment of Figs. 2A, 2B are made of plastic and molded in one piece.
In the exemplary embodiments shown, the two or one of the two connecting elements may be relatively rigid. In particular when the second connecting element is relatively rigid, it is ensured that because of this greater rigidity the shielding part is forced, when the control means move in the direction of the needle tip, to move straight along the needle to the needle tip, while in the substantially stretched position of the two connecting elements the shielding part comes to lie at the needle tip. Of importance is therefore that when the connecting element 7 in Fig. 1A is pushed upwards in the direction of the arrow P, the connecting element 8 as a more or less rigid element moves the shielding part 4 upwards along the needle 2. The connecting element 7 can be pushed upwards by hand or a single finger; it is also possible to move the whole hypodermic syringe with the control means 5 backwards relative to the needle tip along an available projection of whatever object in the space where the injection is administered.
In the resting position, the control means 5 assume a position in which the connecting elements 7 and 8 make an acute angle. In this resting position, the shielding part 4 is at such a distance from the needle tip that this part does not hinder the administration of an injection. When the connecting element 7 is pushed upwards, the control means are finally brought into a substantially stretched position in which the shielding part 4 comes to lie around the needle tip .
The invention is in no way limited to the exemplary embodiments described herein with reference to the drawing, but comprises all kinds of modifications thereof, of course as far as they fall within the scope of protection of the annexed claims. In particular, it is observed that also the connecting element 7 may be relatively rigid, while the connecting element 8 may be relatively flexible.
