Definitions
- Needle protection device for a syringe and injection device comprising a syringe and this protection device.
- the present invention relates to a needle protection device for a syringe which comprises a needle, a tubular body at the distal end to which the needle is fixed, and an injection piston mounted to slide in the body, this device comprising a needle protector substantially coaxial with the body of the syringe; a protective support secured to said body or provided with means for securing to said body; a spring disposed in abutment between the support and the protector, the support and the protector being movable relative to each other between a retracted position of the protector in which the needle of the syringe is released and the spring is locked in a compressed state, and a deployed position of the protector in which the needle is disposed inside the protector and the spring is, at least partially, relaxed; and means for unlocking the spring.
- the invention applies in particular to the field of single-use pre-filled injection syringes, intended in particular for intramuscular or subcutaneous injections.
- document US 5,591,138 describes a device of the aforementioned type, which can be used in one of the following two ways: once the injection has been carried out with one hand, the user actuates the unlocking means with his other hand to release the compression spring and allow the protector to deploy around the needle. Or else the needle is pressed deep enough into the patient's skin to cause the spring to unlock, the latter not being able to relax because of the support of the protector against the patient's skin; in this case, the spring relaxes when the entire device is removed from the patient.
- This type of device therefore requires, in order to obtain the desired deployment of the protector, either manipulation with two hands or the support of the protector on the patient's skin. This manipulation does not guarantee a great convenience of use for the practitioner, nor a great comfort for the patient. These devices therefore remain little used because of use too far from the current use of an injection syringe.
- the decompression energy of the spring is often released violently, without possible control by the user, which causes a certain instability of the device in the hand of the user.
- rigid locking of the protector in the deployed position is only possible by handling the device with two hands.
- the object of the present invention is to propose a protection device which allows the protector to be deployed by the same hand as that which holds the syringe, with a simple triggering gesture without the protector having to press against the patient, and possible control of the movement of the protector by the user.
- the invention relates to a protection device of the type defined above and for which the spring has, in the locked state, a predetermined force greater than the pushing force necessary to move the plunger of the syringe over substantially its entire injection stroke, and the unlocking means comprise a digital support flange, integral with the protector, and suitable for, on the one hand, during the sliding of the piston for injection, transmit to the spring a force compression less than said predetermined force, and secondly, when the piston is at the end of the injection stroke, transmit to the spring a compression force greater than said predetermined force.
- the thrust force is at least equal to the sum of the injection force, and the detachment and sliding forces of the piston inside the body of the syringe;
- the collar is located at the proximal end of the protector; - The length of the protector is substantially equal to that of the body of the syringe;
- the means for securing the protective support to the body of the syringe comprise means for fixing said support on the neck of the syringe
- Said fixing means comprise at least one hook for clipping the neck of the syringe
- the support and the protector are mounted in rotation relative to each other between the retracted position of the protector and an unlocking position of the spring;
- the unlocking means comprise on the one hand at least a first groove formed in one of the support and of the protector, and at least partly inclined relative to the axial direction of the body of the syringe, and on the other hand at least one pin integral with the other of the support and the protector, and received in said first groove, the groove and the pin cooperating to guide the support and the protector in rotation relative to each other between the retracted position of the protector and the unlocking position of the spring;
- At least a second groove for receiving the pin, communicating with the first groove, is formed in that of the support or of the protector in which the first groove is formed, said second groove extending substantially in the axial direction of the body of the syringe so as to be able to guide in translation the support and the protector with respect to each other between the unlocking position of the spring and the deployed position of the protector;
- locking means in the deployed position of the protector;
- Said locking means comprise on the one hand at least one tongue secured to the support, and on the other hand at least one deformable hook, secured to the protector, each tongue and each hook respectively provide two substantially conjugate bearing surfaces, suitable for radially deform the corresponding hook when the support and the protector pass from the retracted position to the deployed position of the protector, and each tab and each hook respectively provide two substantially conjugate axial abutment surfaces, adapted to lock the support and the protector relative to each other in the deployed position protector;
- control means comprise on the one hand a removable cap adapted to be disposed around the needle of the syringe before use, and on the other hand deformable tongues formed at the distal end of the protector and delimiting a passage opening whose diameter is, when said tabs are not deformed, less than the maximum diameter of the cap.
- the invention further relates to an injection device comprising on the one hand a syringe which comprises a needle, a tubular body at the distal end of which the needle is fixed, and an injection piston mounted to slide in the body, and on the other hand a needle protection device which comprises both a needle protector substantially coaxial with the body of the syringe, a protector support secured to said body or provided with means for securing to the body of the syringe, a spring placed in abutment between the support and the protector, the support and the protector being movable relative to each other between a retracted position of the protector in which the needle of the syringe is released and the spring is locked in a compressed state, and a deployed position in which the needle is disposed inside the protector and the spring is, at least partially, relaxed, and means for unlocking the spring , wherein the needle protection device is as defined above.

- Figure 1 are shown in perspective a syringe 1 and a protective assembly 2.
- proximal and rear are synonymous, like the terms “distal” and “front”.
- Syringe 1 is a standard shape glass syringe, intended for single use. It contains a liquid to be injected, intramuscularly or subcutaneously, into a patient. It has for this purpose a body 4, a needle 6 secured to the distal end of the body 4 and a piston 8.
- This piston conventionally comprises a rod 10 provided at its distal end with a pusher 12 not visible in FIG. 1 and a support head 14 on which is intended to rest the thumb of the practitioner's hand.
- the body 4 of the syringe has in its proximal part a neck 16 circumferentially delimiting two diametrically opposite ears 18, intended normally, especially in the absence of the assembly 2, to form bearing surfaces for the index and middle finger of the practitioner when handling the syringe and injecting the liquid therein.
- the protection assembly 2 of general axis X-X, essentially comprises, as shown in FIG. 1:
- a support 20 of generally tubular shape
- a protective sleeve 22 disposed coaxially with the support 20 and of diameter greater than that of the support
- the support 20 comprises a main section 26, substantially cylindrical and of internal diameter substantially equal to the external diameter of the body 4 of the syringe 1. This section 26 is extended at its proximal end by a secondary section 28 of larger inside and outside diameters than those of the main section 26, forming a radial shoulder 29.
- the proximal section 28 is provided with means 30 for fixing to the syringe neck 16. More specifically, these means 30 comprise on the one hand a pair of diametrically opposite deformable hooks 32, also visible in FIG. 1. Each of these household hooks a substantially frustoconical ramp surface 32A flaring towards the free end of the section 28, intended to be pushed elastically by the ears 18 of the syringe neck 16 when the support 20 is attached to the syringe 1.
- the hooks 32 are distant of the shoulder 29 by a distance substantially equal to the thickness of the ears 18. The hooks 32 thus form a means of clipping the syringe neck 16.
- the fixing means 30 also comprise protuberances 34 (FIGS. 1, 4 and 6B) which project radially towards the inside of the section 28. These protuberances are adapted on the one hand to form means of angular indexing, to within 180 °, of the neck 16 of the syringe, and on the other hand of the rotation locking stops for this neck 16 when the latter is retained axially between the hooks 32 and the shoulder 29. Two through grooves 36 are formed one opposite the other in the main section 26.
- Each groove consists of a first rectilinear part 38 which extends substantially along the axis XX of the support 20 over a length greater than that of the needle 6, and of a second rectilinear part 40 which extends in an inclined manner with respect to the same axis XX.
- the inclined part 40 opens into the proximal end part of the main groove part 38, forming a V, the point of which is directed towards the proximal side of the assembly 2.
- the main section 24 has at its distal end a first pair of diametrically opposite tongues 42, each located in the extension of the grooves 36 (FIG. 5).
- These tongues 42 have an internal face 42A of substantially cylindrical shape and an external face 42B substantially frustoconical, diverging towards the rear.
- the main section 24 comprises a second pair of diametrically opposite tongues 44, situated between the tongues 42 following the circumference of the distal end of this section. They have an outer surface 44A which is substantially frustoconical, diverging towards the front, and a distal surface 44B which is substantially planar.
- the protective sleeve 22 is of length substantially equal to that of the body 4 of the syringe 1. It consists of two cylindrical sections 46 and 48, the proximal section 46 having a diameter slightly greater than that of the main section 48. These two sections are connect by forming a radial shoulder 49.
- the sleeve 22 integrally comprises, in its proximal part, an external flange 50 in the form of two diametrically opposite ears 52 (FIG. 4).
- two diametrically opposed nipples 54 are integral with the sleeve ( Figure 5). These two pins are adapted to be received and guided respectively in the two grooves 36 of the support 20, the support and the sleeve being thus movable relative to each other in translation along their common axis and in limited rotation around the same axis when the pins 54 are in the groove parts 40.
- the support 20 and the sleeve 22 are movable between a retracted position of the sleeve, in which most of the sleeve covers most of the support and the pins 54 are located at the distal end of each of the parts of inclined grooves 40, as shown in FIGS. 2 to 7, and a deployed position of the sleeve in which the latter extends axially projecting from the support and the pins are located at the distal end of the longitudinal groove part 38, as shown in Figures 11 to 13.
- these extreme positions correspond respectively to an injection configuration in which the needle 6 of the syringe 1 is released and intended to be inserted into a patient, and to a protection configuration in which this needle is surrounded by the protective sleeve 22.
- the proximal part of the sleeve 22 also includes internally a pair of deformable hooks 56 diametrically opposite.
- Each of these hooks has on the one hand an internal surface 56A of substantially frustoconical shape diverging towards the front, complementary to that of the internal surfaces 44A of the tongues 44 of the support 20, and a proximal surface 56B substantially planar (FIG. 3).
- these hooks 56 In the retracted position of the sleeve, these hooks 56 extend inside the recesses 26A formed in the support 20.
- the faces 56B of the hooks 56 are in axial abutment against the tongues 44, the hooks and tongues thus forming a rigid locking assembly in the deployed position.
- the sleeve 22 is moreover provided at its distal end with a crown of deformable tongues 58, the distal edges of which form a substantially circular opening 60, of diameter less than the inside diameter of the main section 26 of the support 20.
- the spring 24 is a spiral spring, disposed between the protective sleeve 22 and the protective support 20. More specifically, the spring is housed between the shoulder 29 of the support 20 and the shoulder 49 of the sleeve 22. In the retracted position of the sleeve, the spring 24 is in a compressed state, thus having a decompression energy linked to the stiffness of the spring and to the difference between the length of the spring in the rest state and its length, noted L in FIGS. 2 to 7 , in the compressed state.
- the spring 24 has an additional compressive force threshold which corresponds to the minimum force necessary to further compress the spring from its initial compressed state in FIGS. 2 to 7.
- the stiffness of the spring and or the length of initial compression L are chosen so that this force threshold is greater than the thrust force necessary to move the piston 8 of the syringe 1 over its entire injection stroke. More specifically, the force of the spring in the locked state is greater than the sum of the injection force, that is to say of evacuation of the liquid outside the needle 6 of the syringe 1 , and detachment and sliding efforts of the pusher 12 inside the body 4 of the syringe.
- the protection assembly 2 further comprises a cap 66 of generally tubular shape, shown in FIGS. 1 and 6A.
- the cap 66 is adapted to surround the needle 6 before using the syringe 1.
- This cap is closed at one of its ends and its opposite end is formed by an annular ring 68 of outside diameter suitable for both being conjugated with the surface 42A of the hooks 42 of the support 20 and be greater than the diameter of the opening 60 formed by the tongues 58 of the protective sleeve 22.
- the inner face of this ring 68 is intended to adhere to the glass base 67 of the syringe body 4 where the needle 6 is fixed, in particular to guarantee a certain seal against bacteria.
- the protection device 2 is assembled in its retracted configuration, that is to say that of FIGS. 2 to 7.
- the protective sleeve 22 is therefore threaded around the support 20 from the distal end of the support, placing the spring 24 between them. More precisely, the sleeve is moved axially towards the rear relative to the support, while radially outwardly deforming the hooks 56 by means of a suitable tool, at least until they reach axially the front part of the longitudinal recesses 26A.
- the glass syringe 1 is pre-filled with a liquid to be injected into a patient.
- This syringe is fitted with the cap 66 which encloses the base 67 of the syringe body 4.
- the syringe and the cap are then inserted inside the assembly 2 to form the injection device, as shown in FIGS. 6A and 6B. More specifically, the body 4 of the syringe is moved substantially axially inside the support 20 until the syringe neck 16, indexed by the protuberances 34, snaps inside the proximal section 28, radially outwardly deforming the hooks 32. The ears 18 of the syringe neck 16 are then retained axially by the hooks 32, while the peripheral protuberances 34 retain the syringe neck, and therefore the syringe, in rotation relative to the support 20.
- the syringe neck 16 is completely clipped inside the section 28, it can no longer fulfill its usual role of forming a support surface for the practitioner's index and middle finger.
- This support function is performed by the flange 50 integral with the sleeve 22.
- the practitioner can then manipulate the syringe by resting his thumb on the support head 14 of the piston 8 as usual, and by resting his index and middle fingers on the faces of the ears 52 directed towards the needle 6.
- the cap 66 extends projecting outside the protective sleeve 22.
- the practitioner When the practitioner is ready to inject the liquid contained in the syringe, he withdraws the cap 66 by pulling it axially forward. The ring 68 then crosses the opening 60 by deforming the tabs 58. Once the cap 66 removed, the tabs 58 return to their initial position. The passage hole 60 at the distal end of the sleeve, with a diameter smaller than the outside diameter of the cap 68, then prevents the cap from being replaced around the needle. The cooperation of the cap 66 and the tongues 58 thus form a means of controlling the first use of the injection device.
- the practitioner then withdraws the needle from the patient.
- the practitioner exerts additional pressure on the piston rod 8.
- This pressure must be greater than the predetermined force produced by the spring 24 in the locked state, so that this spring is more compressed. and goes from its length L to a shorter length L ′, as shown in FIGS. 8 to 10.
- the protective sleeve 24 moves axially towards the proximal end of the support 20
- the practitioner performs this movement by exerting a corresponding pressure by means of his index and middle finger on the ears 52 of the flange 50 of the sleeve 22.
- This pressure causes, in combination with the translational movement, the rotation of the protective sleeve 22 around the syringe support 20, the pins 54 being guided by the inclined groove parts 40.
- This rotational movement is continues until the pins reach the proximal end of this groove part 40, that is to say the proximal end of the longitudinal groove part 38, as visible in FIG. 9.
- the device 2 is then in the unlocking position of the spring 24.
- the practitioner releases the pressure which he exerted until then on the flange 50, allowing the spring 24 to relax until a state of rest.
- the pins 54 move in translation inside the longitudinal groove part 38, up to the distal end of the latter as shown in FIG. 13.
- the translational movement of the sleeve 22 relative to the support 20 is controllable by the practitioner, if the latter gradually releases the digital retainer which he exercises the flange 50.
- the pins 54 When the pins 54 have arrived at the distal end of the groove 36 (FIG. 13), the protector is in its deployed position.
- the hooks 56 pass through the longitudinal recesses 26A of the support, until they slide along the distal tongues 44 of the support 22, by cooperation of their complementary surfaces 56A and 44A.
- the tabs 44 hold the hooks 56 in position by cooperation of the surfaces 56B and 44B, so that the protective sleeve 22 cannot be returned to its initial position.
- the sleeve 44 cannot be easily torn off from the support 20 since the pins 54 are in abutment against the distal bottom of the longitudinal groove part 38 (FIG. 13), the tongues 42 forming this bottom being radially held between the body syringe 1 and sleeve 22.
- the injection device according to the invention is thus simple to use, while allowing the practitioner to control the movement of covering of the needle by the protective sleeve.
- the number of parts of which the protection assembly 2 represented is reduced to three.
- the device according to the invention is adaptable to different types of syringes, both in terms of shapes and volumes. This device therefore has the advantage of not calling into question the general shape of the syringes used and consequently does not entail any modification of the industrial processes for filling these syringes.
- Various variants of the device according to the invention can be envisaged:
- the pins 54 and / or the flange 50 of the protective sleeve 22 can be attached to the sleeve 22 and not made in one piece with it; - unlike the device described, the pins 54 can be made on the external surface of the protector support 20 and the guide groove 36 formed in the protective sleeve 22;
- the support 20 can be made in one piece with the syringe body 4; and / or - the protuberances 34 of the means 30 for fixing the support 20 on the syringe neck 16 can be eliminated and possibly replaced by one or more hooks similar to the hooks 32 described above, all of these hooks axially retaining the neck 16 relative to the support 20 for any relative angular position between the syringe 1 and the support; in this case, the syringe 1 is free to rotate inside the support 20, which in return provides greater ease of attachment of the protective assembly 2 to the syringe (absence of indexing).
