Definitions
- the present invention relates to a device for syringes and self-locking safety needles with protective tab for the operator, glass and or disposable plastic to make unusable after a first injection a needle and a medical syringe, whether intended vaccines or medical care, laboratories, veterinarians and any other medical activity.
- the syringe is intended for the injection of drugs or liquids into humans and animals.
- this invention relates to a medical device for administering a medicament to a patient, comprising a syringe whose plunger 24 defines a reservoir for the medicament, a needle cannula 26 coupled to a front end of the barrel, and a plunger with a plug positioned in the cylinder that drives the medication while moving.
- the medical device also comprises a cap 22 disposed on the needle cannula on which it slides from a first position, in which the forward tip of the needle cannula is exposed, to a second position in which this same tip is covered by The hairdo.
- An actuation mechanism connected to the cap comprises a constraint element, coupled to the cylinder and the cap, which moves the latter to the second position.
- a trigger element i liberally holds the actuator element under load and freely holds the cap on the first position.
- the actuator element can release the cap either by manual control or by interaction of the pusher.
- the invention relates to a medical syringe plastic disposable non-reusable very economical because without needle cap.
- the needle being housed inside the piston handle.
- a neutralization device 1 with U-spring rods connecting the two parts of the handle is proposed.
- the control suction device 2 is constituted by an elongated syringe tip centered by a sleeve 3 that can be glued through an ovular opening 4. Models of pre-filled syringes are described. One where the needle cap serves as a piston handle.
- the base of the needle is the body of the syringe which is capped by a plug which must be pushed by an independent handle, or by an elastic piece intended to be inflated by a conventional syringe whose manipulator has a unique copy serving him for all vaccinations.
- a passive needle shield comprises a body having distal and proximal ends and a cavity for receiving a medicament cartridge, and a sliding slider on the body between drawn and developed arrangements for exposing and covering, respectively, a needle. attached to the body, the screen being constrained in the developed position.
- Ratchet type members depart from the screen and include pawls that cooperate with pawls on the body to maintain the screen in its retracted position. A syringe is inserted into the needle guard, and the needle of the syringe inserted into the patient.
- the plunger of the syringe is pressed to inject the drug and to deflect the latch-like elements to disengage the pawls and release the drug and to deflect the latch-like elements to disengage the pawls and release the latch. 'screen.
- the screen then automatically advances to the expanded position. In the developed position, cooperation elements on the screen and the body cooperate with each other, thereby aiming for undesirable removal of the screen.
- F 2787718 and FR2787719 the invention fig.
- a disposable plastic or glass syringe that can not be used for a second injection and another person. It is intended for injection of solution and pharmaceutical liquid in humans and animals, (medical and pharmaceutical use).
- the device according to the invention overcomes these disadvantages.
- the device comprises according to a first feature, a needle holder or hollow cannula of variable diameter glass or molded plastic, adapted according to the gauges and needle lengths, which has the distinction of being introduced into the base d a syringe body to be blocked there.
- This support of variable length (depending on the size of the syringe) enters the piston at its center or offset to block the end of injection.
- the device comprises in fact according to a second characteristic, a one-piece hollow piston made of glass or molded plastic of variable size and diameter developed at its center and or offset from its axis so as to receive the tip of the needle holder or any other part to block and so not to perform a second injection.
- the device has indeed a third feature, a one-piece syringe body of molded glass or plastic of variable size and diameter whose base consists of lugs for locking the needle holder.
- the device also comprises, in fourth characteristic, a one-piece syringe body molded in green or plastic of variable size and diameter, a molded receptacle for receiving a tongue and thus, after a tilting of the latter, enclose the needle and offer protection for the operator.
- the device also comprises fifth characteristic, a plastic tongue of variable length and variable width and articulated molded to cap a needle after injection and thus make it harmless for the medical operator.
- the needle holder fully molded part, can be of variable length and have additional notches for allow to offer a better resistance to tearing compared to the size of the syringe.
- the support or base being hollow at both ends and slotted on one end, inner diameter is a function of the diameter of the needle and its technical characteristics, the support or base can be used reversibly according to its use, that is to say that is to say that it can be inserted into the body of the hollow and conical piston then comes to take position in the bosses to be clipped and at the end of the injection the other end is housed in the clips thanks to the pins of the body of syringe and thus render the syringe unusable.
- the piston integrally molded piece, can be of varying length and diameter. It is hollow and conical in its base and thus offers the possibility of integrating the needle support in both directions. This action makes it possible to block the piston since provided with lugs it is thus blocked.
- the number of pins is not limited and are reproduced as necessary in the hollow part of the piston. This provision for better blocking especially for large capacity syringes.
- the syringe body integrally molded piece may be of varying length and diameter. It is in its inner base provided with several lugs for locking the needle holder after insertion.
- the syringe body integrally molded piece has a receptacle at its end for housing a removable tab and tilting.
- the removable and tilting tab fully molded part, integral part of the body of the delivered syringe ready to use, allows as soon as it tilts forward to lock the needle and thus protect the operator after his injection
- Figure 1 shows the assembly of the mounted syringe ready for use.
- Figure 2 shows the body of the syringe.
- Figure 3 shows the piston
- Figure 4 shows the support or base of the needle
- FIG. 5 shows the protection tab
- Figure 6 shows the needle guard
- Figure 7 shows the variant of the body of the syringe
- FIG. 8 shows the piston variant
- FIG 9 shows a variant plug
- FIG. 10 represents an alternative cylindrical tube
- these devices comprise a set fig. 1 page 1/9 representing a self-locking syringe, a self-locking needle (5), a needle hub with safety (3), a protection tongue (4), a groove for housing the needle (6), a piston (2) , a base with clips (7), a syringe body (1), a needle cover (8).
- the device comprises a set fig.2 page 2/9 a syringe body (10), an inner boss (11), a conical groove
- the device comprises a set fig.3 page 3/9, a piston
- a support needle and or hollow cannula (20), having a number of recess on its lower part (21) surmounted by several conical bases and or flat (22), of a stop (23), a hollow portion with a narrowing (24).
- the device comprises a set fig. 5 page 5/9, an attachment pin (25), a hollow protrusion (31), a curved groove (30), a convex and concave shape (26), a shape at its concave end ( 27), several grooves (28), a slot (29).
- the device comprises a cover for protecting the needle (32), a conical cavity at its end (33).
- a piston formed of four faces crosswise along its length, a minimum face has a projection thus forming a fin (unlimited number) (37) surmounted by a shoe (38).
- a split cylindrical tube its lower part shows a throat (41), its upper part an internal boss (42).
- the entire body of the syringe will have a size of approximately 5 mm to 150 mm and covers a range of between 0.3 cc and 60 cc.
- the device according to the invention is particularly intended for health practitioners regardless of the field. This device contributes to a better comfort of the use of the syringes and also brings a maximum of security for the actors of health. In addition, the device addresses the issues of safety and reuse of used syringes.
