Embodiment Construction

[0032] A medicament delivery device having a drive mechanism for rotating a rotating member is provided. A medicament delivery device comprising: a housing arranged to receive a medicament container having a piston for sealing the medicament container and displacing the medicament; a medicament delivery mechanism, the medicament delivery mechanism being arranged to push the piston to displace the medicament when activated; and a drive mechanism connected to the medicament delivery mechanism such that when the medicament delivery mechanism is activated, the drive mechanism displaces the medicament The linear motion of the medicament delivery mechanism is converted into torque to rotate the rotating member.

[0033] By providing this torque that rotates the rotating member, the internal system can be driven. According to some embodiments, the internal mechanism may be an indicator system or an energy generating device. Thus, the energy used to deliver the medicament to the pat...

Abstract

The present invention discloses a medicament delivery device comprising: a housing arranged to accommodate a medicament container having a piston for sealing the medicament container and displacing the medicament; a medicament delivery mechanism, the a drug delivery mechanism arranged to push the piston when activated to displace the drug; and a drive mechanism connected to the drug delivery mechanism such that when the drug delivery mechanism is activated, the A drive mechanism converts linear motion of the drug delivery mechanism into torque to rotate the rotating member.

Description

technical field [0001] The present invention relates to a device for delivering a medicament to a patient. Background technique [0002] There are a number of diseases that require regular treatment by medicament injection, and such injections can be performed using injection devices. Various injection devices for delivering medicament injections are known in the art. Another type of syringe pump that gains traction is the bolus syringe device. Some bolus syringe devices are intended for use with relatively large volumes of medicament (usually at least 1 ml and possibly several ml). It can take minutes or even hours to inject such a large volume of medicament. Such high volume bolus injector devices may be referred to as large volume devices (LVDs). Typically, such devices are operated by patients themselves, but they can also be operated by medical personnel. [0003] In order to use an injector device, such as an LVD, it is first supported on a suitable injection site...
