Abstract:
A dual mode automatic injector (10) having a dual mode safety device (18) for preventing the release of the stressed spring assembly (16) except when it is desired to operate the medicament injecting assembly (14) by the stressed spring assembly. The dual mode safety device comprises a first part (66) including a pin portion (70) and an automatic removal portion (76, 78, 80 and 82) fixed to the rearward end of the pin portion. The dual mode safety device also includes a separate second part (68) and a connection (90, 92 and 94) between the first and second parts for (1) enabling the second part to be connected with the first part while the pin portion of the latter is in a safety position in a manual mode position wherein the first part is in rearward motion transmitting relation to the second part and (2) enabling the second part to be removed from the manual mode position while the pin portion of the first part is retained in its safety position. The second part includes a cap portion (88) of a size and shape to be conveniently manually grasped by a user and moved rearwardly in order to effect the removal of the pin portion from its safety position when the second part is in its manual mode position.
Abstract:
An automatic injector apparatus (10) comprising an outer housing (12), a hypodermic needle (50), a first and second medicament ingredient (104, 108) in a first and second container (18, 20); first and second pistons (106, 110) in the respective containers and a releasable stressed spring arrangement (22, 24) capable of being released twice for movement through a first and second piston moving stroke; a first releasing device (166) for release of the spring arrangement to effect movement of the first piston through an ingredient moving stroke causing the medicament to mix with the medicament in the second container; a second releasing device (158) operable in response to a second actuating procedure for release of the spring arrangement to effect movement of the second piston through an operative stroke causing the hypodermic needle to be moved into the tissue of the patient and the liquid medicament to be moved through the needle.
Abstract:
An injection device includes a generally tubular outer body (10) and a medicament cartridge assembly carried within the outer body. The cartridge assembly includes a glass container (14), a charge of medicament (36) disposed within the glass container, a plunger member (28) rearwardly confining the medicament, and a seal (22) for sealing the forward portion of the glass container. A needle (34) has a rearward end disposed proximate the seal, with the seal and needle being movable with respect to one another. A rigid needle cover member (40) is normally maintained in an inoperative position and is movable relative to said body to a protective position wherein the needle cover member extends forwardly to cover the forward end of the needle.
Abstract:
An autoinjector (10) converted from an intramuscular to a subcutaneous mode of injection comprising a housing (14) having a medicament cartridge assembly (32) mounted within the housing means in a storage position for movement out of the storage position and a releasable stressed spring assembly (46) for moving the medicament cartridge assembly means out of the storage position. The stressed spring assembly is operable in response to a manual actuating procedure which does not require compression of the subcutaneous tissue to effect an intramuscular mode of injection by moving the hypodermic needle (40) of the cartridge assembly outwardly of the housing into the muscle tissue at the injection site of a user and a major portion of the liquid medicament of the cartridge assembly outwardly through the hypodermic needle into the muscle tissue of the user. An injection mode converting structure (86) is secured in a subcutaneous mode position for converting the mode of injection effected by the stressed spring assembly from the intramuscular mode of injection to a subcutaneous mode of injection in which the needle cannot extend substantially beyond subcutaneous tissue at the injection site of the user and a major portion of the liquid medicament enters into the subcutaneous tissue.
Abstract:
An automatic injecting device (10) including an elongated housing assembly (12), a stressed spring assembly (14) mounted within the housing assembly (12) so as to be released in response to a predetermined manual actuation procedure, and a medicament cartridge assembly mounted within the housing assembly in cooperating relation with the stressed spring assembly (14) comprising a hypodermic needle (62) and a medicament container (60) housing a forward (80) and rearward (88) individual dosages of different relatively incompatible liquid medicaments mounted therein and separated by a deformable stopper (66). A hub assembly (64) connects an exteriorly flanged necked down forward end portion of container (60) with the hypodermic needle. A separate fitment (90) of molded plastic material is mounted within the interior of the cylindrical glass wall of container (60) adjacent the necked down forward end portion thereof for radially inwardly deforming the stopper (82) during operation and thereby providing an axial by-pass in the periphery thereof.
Abstract:
Un auto-injecteur (10) converti d'un mode d'injection intramusculaire à un système d'injection sous-cutanée comprend un logement (14) à l'intérieur duquel est monté un ensemble (32) à cartouche de médicaments, situé dans une position de repos et pouvant quitter cette position, ainsi qu'un ensemble ressort chargé libérable (46) servant à faire sortir la cartouche de médicaments de la position de repos. L'ensemble de ressort chargé peut fonctionner en réaction à une manoeuvre qui ne nécessite pas une compression du tissu sous-cutané afin, d'effectuer une injection intramusculaire en faisant sortir de son logement l'aiguille hypodermique (40) de l'ensemble à cartouche et ensuite en la faisant pénétrer dans le tissu musculaire au point d'injection d'un utilisateur, puis en transférant une partie importante du médicament liquide de l'ensemble à cartouche jusqu'au tissu musculaire de l'utilisateur par l'intermédiaire de l'aiguille hypodermique. Une structure (86) convertissant le mode d'injection est calée en position d'injection sous-cutanée et sert à convertir le mode d'injection effectuépar l'ensemble à ressort, du mode d'injection intramusculaire au mode d'injection sous-cutanée dans lequel l'aiguille ne peut pas aller sensiblement au-delà du tissu sous-cutané situé au point d'injection de l'utilisateur, et une partie importante du médicament liquide est déposée dans le tissu sous-cutané.
