Embodiment Construction

[0034] Briefly, this specification describes a medicament injection device with a new and innovative trigger configuration, for example in the form of a bolus syringe device, a patch pump or an infusion pump. In particular, the medicament injection device is provided with a cavity configured to receive a corresponding key device. Means disposed within the injection device is configured to detect (e.g., sense) whether the key device has been inserted into the cavity, and trigger the operation of the pump described. Triggering may involve causing the needle insertion mechanism to insert a needle (which may be a hollow needle or a trocar) into a subject (eg, a patient) for receiving an injection of a medicament and / or causing initiation of delivery of a medicament. By triggering the operation of the pump in response to detecting the presence of the key device in the cavity, the possibility of accidental triggering by inadvertently pressing a button or the like is avoided. In th...

Abstract

An injection device (100) comprises: a needle insertion mechanism (111); a medicament delivery arrangement (123) configured to cause injection of a medicament into a patient; and a cavity (102) having an opening (103) for receiving a key device (104). The injection device is configured to respond to detecting the presence of the key device in the cavity by triggering operation of the injection device. The specification also provides a method of controlling an injection device (100) including a needle insertion mechanism (111); a medicament delivery arrangement (123) configured to cause injection of a medicament into a patient; and a cavity (102) having an opening (103) for receiving a key device (104), the method comprising: responding to detecting the presence of the key device in the cavity by triggering operation of the injection device.

Description

technical field [0001] The present invention relates to injection devices, and in particular to triggering the operation of an injection device. Background technique [0002] Syringe or infusion pumps of the type known as patch pumps for delivering medicament injections are known in the art. Another type of syringe pump that is receiving attention is the bolus syringe device. [0003] Some bolus syringe devices are intended for relatively large dose volumes, usually at least 1 ml and possibly several ml. Injecting such large dose volumes may take minutes or even hours. Such high volume bolus syringe devices may be referred to as large volume devices (LVD). [0004] In order to use a patch pump or bolus syringe device (eg LVD), it is first supported on the patient at the appropriate injection site. Once located, the injection is initiated by the patient or another person (user). [0005] Typically, the user performs a number of steps before the medicament injection can b...
