An injection device is described. The injection device includes a stopper having a first conductive element, a barrel having a medicament reservoir sealed at a proximal end with the stopper, and a plunger rod having a second conductive element. The plunger rod is coupled with the stopper to cause forward axial movement of the stopper to expel a medicament from the medicament reservoir. The first conductive element and the second conductive element complete an electrical circuit when the plunger rod is coupled to the stopper.

Injection device

Injection monitoring circuitry is provided for coupling to part of an injection device having a syringe and a plunger rod. The injection monitoring circuitry has an input to receive force measurement data from a force sensor, the force measurement data includes a plurality of timestamped force measurements of force applied by a user to the injection device when an injection is administered to an injection site. Processing circuitry is provided to determine from the force measurement data when an end of injection has been reached, the end of injection corresponding to the plunger rod having reached an end position in a distal portion of the barrel of the syringe during administration of the injection by the user. Machine readable instructions and an injection monitoring method are also provided.

A catheter and associated method for taking a plurality of samples from within a length of a blood vessel. The catheter includes an elongate central body arranged to be inserted into and positioned along a central region of a blood vessel. A plurality of collection areas are defined along the elongate central body for collecting samples at the central region of the blood vessel. A plurality of mixers are provided radially outwardly of the elongate central body and arranged to create a flow of blood from a boundary layer at a wall of the blood vessel to the elongate central body. This enables the collection areas to collect samples from the boundary layer.

Catheter

An injection device including a barrel having a medicament reservoir therein capable of fluid communication with a needle assembly at a distal end thereof and sealed at a proximal end thereof with a stopper. The injection device further includes a plunger rod having a distal rod end which is couplable with said stopper, wherein, when the plunger rod is coupled to the stopper, forward axial movement of the plunger rod causes forward axial movement of the stopper coupled thereto into the medicament reservoir in order to expel medicament through the needle assembly. Further, the plunger rod can be decoupled from the stopper by applying a rearward axial force on the plunger rod, said rearward axial decoupling force being less than a rearward axial force required to move the stopper rearwardly with respect to the barrel.

An injection deviceis described having a housingthat receives a syringehaving a needle, wherein the syringe is supported in a syringe carrier. The syringeand syringe carrierare biased by a return springfrom an extended position in which the needleextends from the housingthrough an exit apertureto a retracted position in which it does not. A drive springacts via a drive to advance the syringefrom its retracted position to its extended position and discharge its contents through the needleand a return spring, brought into play when the drive has reached a nominal return position, restores the syringeto its retracted position. The syringe carrieris designed to restrict rearward movement of the syringe so that the injection device is less prone to failure and damage to is components than prior art devices.

An injection deviceis described having a housingthat receives a syringehaving a needle, wherein the syringe is supported in a syringe carrier. The injection devicehas a removable cap. The syringeand syringe carrierare biased by a return springfrom an extended position in which the needleextends from the housingthrough an exit apertureto a retracted position in which it does not. The syringe carrierabuts a surface inside the removable capwhich prevents forward movement of the syringe carrierwhen the cap is in place. The injection device is less prone to failure than prior art devices and is safer should failure occur.
