摘要： Drug delivery devices are described that include an escapement activation assembly. The escapement activation assembly includes a slide having a plurality of pallet engagement portions and a switch engagement portion and a pallet having a plurality of slide engagement portions. A drive is coupled to the pallet to cause the pallet to move relative to the slide to move the plurality of slide engagement portions into and out of engagement with the plurality of pallet engagement portions to allow the slide to move along a path within the drug delivery device. Movement of the slide can cause the switch engagement portion to move out of engagement with an activation trigger of a mechanism of the drug delivery device.

摘要： A medication delivery device includes a disposable portion and a reusable portion. The disposable portion includes a therapeutic agent delivery assembly, and the therapeutic agent delivery assembly includes a needle. The therapeutic agent delivery assembly is translatable from a stowed configuration to a deployed configuration. The reusable portion includes a first rack and pinion mechanism and a second rack and pinion mechanism. The first rack and pinion mechanism is actuatable to translate the therapeutic agent delivery assembly from the stowed configuration to the deployed configuration. The second rack and pinion mechanism is actuatable to translate a plunger and thereby cause the therapeutic agent delivery assembly to deliver a therapeutic agent from the needle.

摘要： A method of delivering epinephrine includes placing a distal end surface of a medical injector into contact with a target location of a patient. The medical injector includes a housing, an energy storage member, and a medicament container containing a dose of epinephrine effective for administration to the patient experiencing anaphylaxis and having a weight of less than 15 kg. The medicament container is coupled to a needle. The medical injector is actuated such that the energy storage member produces a force to move the needle from a first needle position to a second needle position. A distal tip of the needle extends from the distal end surface by a distance of between 7 millimeters and 8 millimeters when the needle is in the second needle position. A portion of the force is exerted to expel the dose of epinephrine when the needle is in the second position.

摘要： Methods of actuating a needle array device can include causing fluid to move through flow channels to needle apertures that are spaced apart from an inflow aperture at different distances where flow channels that have approximately equal pathway lengths and where the fluid can reach tips of the needle apertures approximately simultaneously, which can provide an approximately equal dosage or fluid volume through the tips of the needle apertures.

摘要： A displacement sensing device is configured for a peritoneal dialysis system. The peritoneal dialysis system includes a housing and a syringe. The syringe is disposed on the housing and has a push rod. The displacement sensing device includes a guide rod, a probing module, and a resistance scale. The guide rod is coupled to the push rod, and the probing module is disposed in the housing and is fixed at the guide rod. The resistance scale is disposed at a side of the probing module. The probing module is configured to contact the resistance scale to obtain a resistance value of the resistance scale and determine a displacement magnitude of the push rod. In addition, a peritoneal dialysis system is also mentioned.

摘要： A needle injection array can comprise a plurality of needles that are fluidly interconnected via a fluid manifold. The fluid manifold can be configured to direct fluid from a syringe to arrive at tips of the needles approximately simultaneously. The fluid manifold also be configured to provide approximately equal dosage or fluid volume through each of the needles to an injection site.
