A medicament delivery device includes a generally elongated tubular housing having opposite proximal and distal parts; a needle shield sleeve slidably and coaxially arranged inside the housing with a proximal part of the sleeve protruding a distance outside the proximal part of the housing; a syringe carrier mechanism having a syringe carrier slidably and coaxially arranged within the needle shield sleeve, a syringe having a stopper, a medicament, and a needle, the syringe being coaxially arranged within the syringe carrier; and a holding member connected to the syringe carrier; a first activator member an a second activator member; a drive mechanism adapted to accumulate a drive force for moving the syringe carrier mechanism in a first step and a second step. The second activator member is arranged within an information device for producing audible, visual, and/or tactile feedback to a user about a completed injection.

RAPID FLUID DELIVERY SYSTEM

A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

Auto injector with variable plunger force

Disclosed is a method and an auto-injector for administering a medicament. The auto injector comprising: a housing; a cartridge receiver configured to receive a cartridge comprising a first stopper; a drive module coupled to move a plunger rod between a retracted plunger rod position and an extended plunger rod position, the plunger rod being configured to move the first stopper; a resistance sensor configured to provide a resistance signal indicative of resistance against movement of the plunger rod; and a processing unit coupled to the drive module and to the resistance sensor. The processing unit being configured to: control the drive module to move the plunger rod towards the extended plunger rod position with a plunger rod speed; determine plunger rod position; receive the resistance signal; and control the drive module to adjust movement of the plunger rod if the resistance signal is indicative of resistance against movement of the plunger rod above a high resistance threshold, wherein the high resistance threshold is based on the plunger rod position.

Disposable syringe for use with pneumatic drivers
11684725 · 2023-06-27 · ·

A disposable syringe for use with a pneumatic driver. The syringe has an elongated barrel with a cap secured to the proximal end that has a through bore. A filter is secured to the cap interior of the barrel that covers an opening in the through bore interior of the barrel. The pneumatic driver includes a source of pressurized air; a support for receiving and locating the syringe; and a supply block configured to receive pressurized air from the source and having an outlet for delivery of pressurized air. The supply block is movable between a first position spaced apart from the cap of the syringe and a second position in contact with the cap with fluid communication being established between the outlet of the supply block and the through-bore in the cap.

INJECTION DEVICE

An autoinjector device is provided. The autoinjector device can include an activator unit including an activation housing, an activation guard, and an activation shell such that a portion of the activation guard extends beyond a proximal end of the activation shell. The autoinjector device can include camouflage on a proximal surface to obscure a device lock hole and reduce user confusion around needle orientation.

System and method for controlling a self-injector device
09844628 · 2017-12-19 ·

A cartridge-based computer controlled self-injection device automatically regulates time and dosage administered to a patient. Cartridges can be electronically tagged so the injection device can determine the content, volume, expiration date, and physician prescribed dosage timetable. Authentication verifies the device and ensures the proper patient is using the device with the appropriate therapeutic injectant. Authentication further provides information controlling device operation including expiration dates and clock synchronization. Therapeutic injectant administration statistics, such as date and time of administration of a therapeutic injectant are stored and provide to a health care provider for monitoring. Patients can be notified of nearing or missed administrations.
