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.
Claims20
An injector for delivering a therapeutic product 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 and the vacuum draws the skin of the patient into the injection chamber;
- a cover disposed over the base;
- a vent aperture, wherein the cover is movable relative to the base from a first position to a second position to cause air to move through the vent aperture for releasing the vacuum generated between the flexible layer and the skin, the cover and base being coupled together in both the first position and the second position;
- and
- a flexible isolator disposed over the injection chamber, the isolator having a concave surface for drawing a portion of the skin up into the injection chamber.

- a container or syringe disposed within the injector, the container or syringe containing a therapeutic product;
- a needle shield removably attached to the container or syringe;
- and
- a peelable substrate disposed over the flexible layer for removing the needle shield from the container or syringe.
