Abstract
An injector for delivering a therapeutic product may include a base having a flexible surface that conforms to various body contours of a patient and defines one or more an injection chambers. The injector may have a height that is substantially less than its width, thereby defining a low profile, which provides a larger more stable base that can pinch or stretch the skin in a controlled manner. The larger base can also accommodate larger volumes via multiple injection chambers and/or large combined primary containers.

An injector for delivering a therapeutic product, the injector comprising:
- a base having a bottom surface;
- a flexible layer coupled to the bottom surface of the base that conforms to various body contours of a patient;
- an injection chamber, wherein the flexible layer forms a vacuum with the skin of the patient to draw the skin of the patient into the injection chamber;
- a cover disposed over the base;
- and
- an air vent arrangement, wherein movement of the cover relative to the base causes air to move through the air vent arrangement, the air vent arrangement being configured to close after air is displaced therethrough and to subsequently open to release the vacuum.
