Abstract: An implanter for implanting an implant (3) in an animate being (14) includes a housing (15) on which the inner end of a hollow injection needle (2) is mounted, a plunger (6) mounted in the housing and adapted to extend into the hollow needle through the inner end of the needle, and a locking element (8, 32) for engaging with and retaining the plunger (6) against the force of compression spring (7) in a position where the plunger extends into the hollow needle for a predetermined distance. The locking element is part of a release device (9, 10; 30, 31, 33) which abuts the body (14) of the animate being when the injection needle has been introduced into the body to a predetermined depth to automatically unlock the locking element. The plunger is then forced by the spring (7) against an implant (3) disposed in operation in the injection needle for retaining the implant in the body when the injection needle is retracted from the body.

Abstract: The application describes an administering device, in particular a self-injecting device, comprising a body for holding a container of a substance to be administered, a release mechanism, and means controlled by the release mechanism to discharge the said substance. The body is formed of two parts, one part being movable relative to the other, wherein one part has a trigger and the said release mechanism is partly actuated by the operation of a trigger of the said one part and partly actuated by movement of the other part relative to the said one part, but is only wholly actuated by both the operation of the trigger and the movement of the other part. Thus the discharge means cannot be accidentally actuated.

Abstract: A retractable needle-type syringe having a maximum amount of safety features, including maintaining the needle of the syringe in a retracted and totally shielded position prior to use. After an injection has been given, the plunger rod of the syringe can be operated by one hand of the user in such a manner as to completely and totally disable the syringe and thereby render secondary use of the syringe practically impossible. This feature leaves the other hand of the user out of danger and proximity to the syringe and available to perform other patent-assisting functions. The above multifunctional nature and operation of this invention is accomplished through the use of a minimum number individual components which are uniquely adapted for packaging and cooperative interaction within an elongated cylindrical housing of the syringe.

Abstract: A medicament container assembly for an autoinjector having a power assembly actuatable to cause a power stroke in cooperating relation with said medicament container assembly. The medicament container assembly comprises a container having a forward end, a hypodermic needle having a sharpened end, and first and second liquid medicaments.

Abstract: A medical injector apparatus includes a syringe having a barrel with a lateral projection, a needle, a plunger in the barrel having a portion extending from the barrel opposite the needle.

Abstract: The invention relates to a device for sampling and analyzing blood. It comprises an auto-pricker (1), a magazine (2) for strips, these strips comprising a reactive zone, and a reflectometer (6). Moreover, the magazine (2) is integral with the auto-pricker (1) and the device comprises means (7, 8) enabling the reflectometer (6) and the auto-pricker (1) to be made integral at rest.

Abstract: A safety injector, primarily for self-administered medicaments, is adapted to hold a charged hypodermic syringe and its needle with the needle in a protected retracted position. When a trigger member of the injector is pressed against the skin of the patient, the needle is exposed for producing shallow penetration of the skin, then a plunger actuator is released for producing a forward movement of the syringe a limited distance to cause full penetration by the needle and a coordinated forward movement of the syringe plunger to force medicament from the syringe through the needle in a "tracked injection." A safety mechanism prevents release of the plunger actuator unless the syringe is fully seated within the injector.

Abstract: A method of treating a patient with liquid medicament under circumstances where intravenous injection is not practical but the fast response time of an intravenous injection is desirable, including the treatment of individuals undergoing heart attack symptoms with t-PA.

Abstract: A device for initiating reperfusion treatment of a coronary prone individual prior to the establishment of qualified direct contact personal care at a time during the early minutes or hours after the onset of heart attack symptoms and after qualified personnel have participated by telephone in the decision to initiate such treatment. The device comprises an automatic injector assembly including a releasable force applying assembly, a safety normally disposed in a release preventing position movable therefrom into a release permitting position, a container or containers for separately containing a plurality of separate medicament dosages including a first dosage containing a clot selective coronary thrombolytic agent and a separate second dosage containing a cardiac antiarrhythmic agent and one or more hypodermic needles.

Abstract: A plural dosage automatic injector comprising an elongated tubular housing assembly having side by side first and second medicament injecting assemblies each including a container, a hypodermic needle, a liquid medicament and a plunger within the forward end portion thereof and, first and second stressed spring assemblies in the rearward end portion thereof disposed in operative relation with said first and second medicament injecting assemblies for operating the latter. A manually operable safety device is provided which includes a first safety pin operable (1) when in a safety position with respect to the first spring stressed assembly to prevent actuation and release thereof and (2) when removed from its safety position to permit the actuation and release of the second stressed spring assembly.

Abstract: An injection device useful either for manual injection or mechanical injection, comprises a cross frame having the shape of a revolver. A removable injection syringe having a syringe piston and at least one needle, is mounted on the cross frame, and a syringe cradle secures the syringe to the cross frame. A device is provided for positioning the penetration and to predetermine the degree of penetration of the needle. There is a trigger on the cross frame, and a pawl is actuated by the trigger. The pawl rotates a barrel step by step upon repeated actuation of the trigger. A screw-threaded axle is rotated by the barrel, and a screw-threaded slider is in screw-threaded engagement with the screw-threaded axle and moves forward upon rotation of the axle. The slider and the syringe piston are interconnected to advance the syringe piston stepwise upon repeated actuation of the trigger.

Abstract: An injection device particularly suitable for the intraruminal injection of ruminants is described. The injection device is characterized by a needle carrying means and a needle actuation means, which are operatively coupled such that the needle actuation means permits movement of the needle carrying means from a retracted position to an extended position, wherein the needle is capable of piercing the rumen, only when the needle carrying means is in a preferred orientation (e.g. perpendicular) to the surface of the host animal at the injection site. The injection device is further characterized by a dose delivery actuation means which is responsive to the relative position of the needle carrying means and the needle actuation means such that the dose is delivered to the host animal only when the needle carrying means and the needle actuation means are in a preferred position relative to each other.

Abstract: A blood lancet device for taking blood for diagnostic purposes, having a housing with an exit opening for the lancet, a lancet guide for guiding the puncturing and return movement of the lancet, a spring drive for movement of the lancet and a stop by means of which the lancet is held in a position remote from the part of the body from which blood is to be taken. In the region of the exit opening for the lancet, a release element is present in the housing, the release element being in operative connection with the stop.
