A dose delivery mechanism and a medicament delivery device are presented having a housing holding a medicament container and a power unit, where the power unit has a plunger rod, a drive spring, operably arranged to act on the plunger rod and on the medicament container. A locking ring is operatively engaged with an actuator having a holding ledge that can releasably hold the plunger rod with the drive spring in a tensioned state, and with an actuator sleeve to form a lock that prevents axially movement of the actuator after dose delivery. The locking ring also cooperates with the actuator to generate an end-of-dose delivery signal. An activator is directly engaged with the actuator to provide a well-defined activation point.

The operational parameters of a respiratory apparatus can be controlled through the use of a user interface located on a separate or separable mobile computing device. Sensors or features located on the mobile computing apparatus can be used to adjust the operation parameters or therapy of the respiratory apparatus or otherwise improve the compliance of a patient utilizing the respiratory apparatus.

A medical syringe plunger and a medical finger grip for a disposal syringe having both a dose accuracy function and a plunger pulling out prevention function are provided. A plunger rod includes a first guide groove for guiding the axial movement by a protrusion of a finger grip which extends toward the center of the hole of the finger grip and moves in it, a second guide groove formed at a position on the plunger rod which is rotated by a predetermined angle in the circumferential direction with respect to the first guide groove for guiding the axial movement, an axial direction movement restriction section formed in the vicinity of the end point of the first guide groove for restricting the protrusion's movement in the axial direction, and a protrusion transition section for enabling the protrusion to transit from the first guide groove to the second guide groove.

A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.

A surgical cassette/pack usage tracker for tracking a number of uses for a cassette/pack to prohibit uses from exceeding a maximum amount. A usage tracker system engages with or scans a portion of the cassette/pack to determine the number of uses. In illustrative embodiments, an implement interacts with a film in the cassette after each use and determines remaining uses for the cassette/pack. In other embodiments, an implement interacts with a rotatable wheel that rotates with each use, the implement configured to permit the tracker to identify the number uses and determine remaining uses for the cassette/pack. When a maximum usage amount is reached, the tracker system may issue a warning, eject or reject the cassette/pack and/or disable the surgical device from further use.

In a locking device for locking a plunger rod a plunger rod locking portion is provided for locking a plunger rod of a syringe after use and preventing re-use of the syringe. A chamber is formed inside the plunger rod locking portion for receiving the disc-shaped proximal end of the plunger rod after use of the syringe. The plunger rod locking portion comprises at least one positive locking device configured to positively lock the axial position of the plunger rod by positive-fit engagement with the disc-shaped proximal end of the plunger rod and retain the disc-shaped proximal end of the plunger rod inside the chamber. The locking device provides the functionality of a tamper-evident plunger rod locking device once a dose of medication has been injected by pushing the plunger rod forward, for preventing inadvertent re-use of the syringe.

A portable urinal device includes a base forming a liquid receptacle. Tubing extends from the base to a head member which can be positioned onto genitalia for urination. Suction is provided via a pump or vacuum device to suction urine from the head into the base receptacle.

In an elongated casing, an active agent container connected to an injection needle can be shifted axially by a spring force. Auto-injectors distributed pre-filled and with the springs tensed may be provided with a needle protecting cap to ensure sterility of the needle. When the needle protecting cap is removed as preparation for using the auto-injector, a tensile force can be exerted on the active agent container. Therefore, the active agent container and needle must be prevented from being undesirably pulled forwards. At least one latching tongue prevents the active agent container from being prematurely shifted with respect to the casing, by abutting a flange arranged on a sliding sleeve accommodating the active agent container. When the auto-injector is placed onto the skin, a needle protecting tube is shifted into the casing, forcing the latching tongue away from the flange, thereby freeing the travel path for needle movement.

An injection device is presented having an outer housing configured to receive a syringe, the syringe containing medicament, a movable stopper, and a needle. A plunger rod moves the stopper and a needle shield moves relative to the outer housing between a needle covering position and a needle exposing position, where the needle exposing position is axially rearward of the needle covering position. The needle shield is biased axially forwardly toward the needle covering position. A locking member is axially moveable in the outer housing from a first axial position to a second axial position in response to forward axial movement of the plunger rod. A locking sleeve is axially movable relative to the outer housing between a non-locking position and a locking position, the locking position being axially rearward of the non-locking position, in which axial movement of the locking sleeve is selectively limited by the locking member when in the second axial position.

The present invention relates to a safety injection needle assembly (100) comprising an injection needle (110) affixed to a hub (120) having a stud (130) and a receiving means (140) for receiving a dental syringe, an inner sheath (150) having a slit (190) to receive the stud (130) for retaining the injection needle (110), and an outer sheath (220) and a cap (240) for housing the inner sheath (150). In addition, a pair of outer studs (170) of the inner sheath (150) complements with an outer sheath inlet (230) and a cap inlet (250) for removably engaged and locked via locking means (210). The slit (190) comprises a plurality of terminal ends (200) for receiving and locking the stud (130) via the locking means (210). Preferably, the safety injection needle assembly (100) comprises a sealing member (260) having two set of indicators (280) for indicating position.
