Embodiment Construction

[0028] A wearable fluid delivery device for delivering a fluid medicament to a patient is described below. The device includes a reservoir for storing a quantity of medicament and a dispense interface for delivering the medicament to a patient. The device is configured to deliver the medicament from the dispense interface by injection and to sense partial or complete detachment of the device from the patient's skin.

[0029] As a precaution, the patient may want to place the device 1 under clothing so that the device is not visible during use. The patient may not be aware that the device 1 has become partially detached because he or she cannot see the device. The patient may also not feel the device 1 becoming detached since they may have lost sensation to the part of the body where the device is placed. For example, people with diabetes are known to develop difficulties related to their sense of sight and touch.

[0030] The detachment detection function notifies the patie...

Abstract

A skin-patch type large volume medicament injection device (1) comprising an adhesive surface (21 / 23) for attachment to the skin and a plurality of contact sensors (24) configured to output a signal representing a degree of detachment of the device from the injection site, and an alarm and control function which outputs an alert to the user based on the signal received from the sensors and stops the injection in case the degree of detachment is too large to guarantee further save injection.

Description

technical field [0001] The present invention relates to a partial disengagement sensor, and in particular to a sensor for detecting partial disengagement of a medicament delivery device from an injection site. Background technique [0002] There are a variety of diseases that require regular treatment with injectable drugs. Such injections can be performed using an injection device administered by medical personnel or by the patient himself. As an example, type 1 and type 2 diabetes can be treated by the patient himself by injecting insulin doses, eg once or several times a day. Biopharmaceuticals are increasingly being developed that comprise injectable liquids of higher viscosity and that are administered in larger volumes than known liquid medicaments. Large volume devices ("LVDs") for administering such biological agents may include pre-filled, disposable drug delivery devices, or alternatively, disposable drug delivery devices into which the patient or medical personn...
