Description

DEVICE FOR PROTECTION FROM ACCIDENTAL BITES BY INJECTION NEEDLE

A protec¬ tion device against accidental pricking by injection needles.

Many ways have already developed desti¬ born to protect people, such as nurses, who make injections of pharmaceutical and medical products to patients through syringes with needles, which may prick themselves by manipulating the syringe or the needle after injection given to the patient.

In general, after an injection, the needle must be removed from the syringe and discarded to be de- trout. The most effective protection means consists of covering the needle with a rigid sleeve or cap while it is still mounted on the syringe and then to withdraw the needle from the syringe, leaving the inside of the cap, and throw together the cap and the needle. As the needles are marketed in individual condi¬ tioning constituted by caps ri¬ GIDES closed by a small removable cap or medium ana¬ logue well as sterile packages of the type inviolable "blister" may be reused for packaging cap cover the needle after use and prior to removal of the syringe. This means protec¬ tion is obviously the most economical, but is not very effective because the packaging of commercia¬ lisation needles were not designed to protect against contamination from dirty needles.

The invention particularly aims to provide a simple, effective and inexpensive à_ this pro¬ Haggard. It proposes for this purpose a device for protection against accidental pricking by ai¬ injection Guilles comprising a conical lindrique or cyclic form of cap for holding the needle and having an open end for introduction of the needle, characterized in that the cap comprises means for gripping and holding a cap similar sen- siblement oriented perpendicularly to the first-mentioned cap.

These gripping and holding means may be constituted by a clamping member elastically deformable, for example comprising two legs forming a clip, formed at the closed end of the cap. a cap may thus be used to hold off another cap, perpendicular to the first and wherein the needle will be introduced.

The device of the invention therefore provides an effective protection against accidental punctures by used needles, while having a production cost substantially equal to that of conventional caps of needle packaging.

According to another characteristic of 1'invention, the cap has a cross-section polygonal outer contour, and the city pré¬ clamping member defines an inner contour housing polygonal shape and dimensions corresponding to those of capu¬ Chon.

Thus, it ensures the immobilization in rotation of the cap that. is mounted in the cited pré¬ clamping member.

According to yet another feature of the invention, a tubular sleeve is slidably mounted on the cap so as to open cover 1'extrémité of the cap and extend beyond the latter.

This way provides additional protection, when the needle is of the type with two ends poin¬ kill, one of which is used for injecting a pro¬ Duit to a patient and the other is used to per- drill a shutter of a tube containing the product to be injected. In this case, the aforementioned tubular sleeve may completely cover the needle housed in the cap, avoiding the risk of such punctures acciden¬.

According to an alternative embodiment of the invention, the engagement means and retention compren¬ NENT at least one elastically deformable tab formed along the cap.

This tab may be used to hold another cap of the same type, when engaged, under the tab of the other cap.

In an alternative embodiment of the invention, applicable in particular to the case of insulin injection needles, the clamping member is designed to take and maintain a small-diameter interlocking sheath on the needle.

The invention will be better understood and other features, details and advantages thereof appa¬ raîtront more clearly on reading the following description with reference to the accompanying drawings in which Figure 1 schematically shows a dis¬ positive protection of the invention; 2 illustrates schematically the use of this device; Figures 3, 4 and 5 show smiling va¬ embodiment of this device.

We will first refer to Figures 1 and 2 showing a first embodiment of the device according to the invention. This device essentially comprises a Puchon 10 ca¬ generally cylindrical or frustoconical very similar to conventional caps used for packaging needles in the anté¬ higher technique. This cap 10 has an open end

12 introduction of a needle and a closed opposite end 13. The open end 12 of the capsule is gé¬ neral delimited by a cylindrical collar 14 receiving a removable cap or other similar closing means. At its closed end, the cap 10 is extended longitudinally by a member 16 and socket 'for holding the cap 10 of another device according to the invention or of a conventional cap needle packaging used in the prior art.

The organ of gripping and holding instrument 16 comprises two tabs 18 elastically deformable, pincer or clamping jaws. Both lugs 18 define between them a housing having a shape and dimensions corresponding to those of the cross section of the cap to receive. Use of this device is extremely simple: as shown in Figure 2, it suffices to introduce a device 10 according to the invention or a vector ca¬ conditioning Puchon the side opposite to its open end, in the organ of gripping and holding 16 of another device 10 according to the invention, and sliding the first device or the first capu¬ chon in the gripper 16 and retention of the second device until it is firmly held by this body 16, due to the elastic deformation of the latter. A person can then hold the assembly thus formed by one of caps 10 and insert a needle 20 mounted at the end of a syringe in the other of capu¬ Khons 10 without any risk of pricking the fingers. The inner surface of the end flange 14 of the cap 10 is provided to immobilize in rotation the ring 22 for mounting needle 20 on the syringe. Thus, when the needle is fully inserted into the cap 10, and its mounting ring 22 is immobilized in rotation inside the collar 14 of the ca¬ Puchon, simply a rotation of the syringe to disengage from the the needle then remains inside the cap 10. it is then put on the collar 14 the closure cap of the cap 10, and discard the chon capu¬ containing the needle, after removing the cap Body of gripping and holding 16 of the other dispo¬ operative part.

In the embodiment shown in Figure 3, the cap 10 of the device according to the invention has a cross-section polygonal outer contour, for example hexagonal, and the member 16 gripping and maintenance provided at the closed end of the cap defines a hexagonal inner contour housing corresponding to the hexagonal outer contour of the cap 10. Thus, when another cap 10 is inserted into this socket member 16 and holding, it is automatically immo¬ bilisé rotated.

Furthermore, needle 20 packaged in this device may be of the type extending from either side of the ring 22 for mounting on a syringe and terminating in two. pointed ends, one of which 24 is used for injecting a product to a patient and the other 26 is used to puncture a fer¬ meture closure member of a small tube containing the product to be injected, this small tube being housed in within the body of the Ringue se-.

In this case, when the needle is condi¬ tioned in the device 10 of Figure 3, the mounting ring 22 is accommodated inside an extension tu¬ lary 28 of collar 14 of the device and the part of the needle terminating in the tip 24 is inside of the cap 10, while the opposite portion of the needle having the other tip 26 protrudes outside the device and is normally covered by a tubular cap 30 which is mounted on the prolonge- ment 28 of the collar 14 and abuts the latter. The device according 1'invention may then comprise a tubular sleeve 32 which is mounted coulis¬ sant on the cap 10 and the collar 14 and which has a lon¬ LATIONS sufficient to overlie and completely hide part of the needle terminating in the tip 26 'when it is pushed to the right in FIG 3.

The left end of the sleeve 32 may take com¬ a flange or an internal shoulder 34 forming a stop on the flange 14. This device is used in the manner sui¬ boasts: when one wishes to use the needle 20 housed in the device according to the invention, removed bou¬ chon 30, is slid to the right sleeve 32 to hide the end 26 of the needle and the approach of a syringe device in which was placed a tube containing injectate. By the end 26 of the needle, the closure cap is perforated of the tube, is fixed for example by screwing the ring 22 of the needle on the nozzle corresponding end of the syringe, and then the cap is removed 10 to leave ap¬ appear the other end 24 of the needle.

After injection of the product to a patient, brings the cap 10 on the end 24 of the needle, holding the cap by means of another device lon se¬ the invention and as shown in Figure 2, en¬ gage ring 22 of the needle inside the prolonge¬ ment 28 of the collar 14, separating the needle from the syringe by rotation of the latter, it raises the syringe and replace the cap 30 on the extension 28 of the collar 14 of the device to hide the end 26 of the needle.

At this time, an accidental puncture by the tip 26 of the needle is always possible.

therefore gives the body 36 of the plug 30 a cross section identical to that of the cap 10 of the device according to the invention, allowing to mount the body 36 of the plug into the gripper 16 and retention of a device according the invention, to manipulate and place on the extension 28 of the cap 10 without the risk of puncture by the tip 26 of the needle. 4 shows an alternate embodiment 'tion of the device of Figure 3.

In this alternative embodiment, the means for gripping and holding comprise at least one elastically deformable tab 38, which extends along the cap 10 of a relatively small length, for example from the collar 14 thereof and towards the closed end of the cap.

In the example shown in Figure 4, the positive dis¬ comprises two legs 38 elastically deform ables which are diametrically opposed.

The plug 30 associated with the cap 10 also includes at least one, for example two lugs elasti¬ cally déformableε 40 of the same type, which extend along the body 36 of the cap toward its closed end.

This device is used as follows: to hold a cap 10 in which a needle after one use dé¬ reintroduce sire, we take another device according to the invention, the same type, it is oriented perpendicular to the cap 10 that it is desired to hold and engages a lug 38 of this tif disposi¬ under the lug 38 of the cap 10 that one wants to keep, between this leg 38 and the cap 10 itself.

Similarly, for holding a plug 30 which is de- sire put on the cap 10 to close its open extré¬ moth, is introduced one leg 38 of the other dispo¬ operative part under a tab 40 of the plug 30.

5 shows another alternative embodiment of the invention, applicable in particular to Ai- insulin injection Guilles which fit on reusable systems of metering and injection automa¬ ticks.

These needles are of the type extending on either side of a mounting ring 42, as the needle shown in Figure 3, and portion 44 for the injection of insulin is often covered with a cylindrical sleeve 46 having an outer diameter very low (of the order of 3 mm), the whole needle sheath 46 being covered by a cap 48 whose green or- end engages on the ring 42 of mounting the needle.

These needles are disposable after use principle, but some people leave the mon¬ tees permanently on the dosing system and automatic injection and trying after each injection, replacing the sheath 46 of the part 44 of the needle , it is difficult to do without risk of poking.

The invention then provides that 1'extrémité fer¬ MEE of cap 48 is provided with a member 50 for gripping and holding the sheath 46, which allows not to hold the sheath 46 with the fingers, but via the cap 48, when trying to put on the portion 44 of the needle.

In general, the invention allows to manipulate a cap or sleeve that is to be placed on a needle or wherein it is desired to introduce a needle, without taking the cap or the sheath di¬ rectly with the fingers, eliminating the risk of inadvertent puncture by the needle, and which increases the safety for sure caregivers.
