An injection device comprising a housing; a securing arrangement for securing the injection device against an injection site of a patient; a needle insertion mechanism configured to cause insertion of a needle into a patient when the injection device is secured against the injection site of the patient; a medicament delivery arrangement configured to cause injection of a medicament into tissue of the patient at the injection site; and a medicament retention sensor configured to detect retention of medicament in the tissue of the patient at the injection site, wherein the injection device is configured to respond to detection of swelling of the tissue of the patient at the injection site by causing provision of an alert and/or by causing suspension or halting of injection of medicament.

An injector device and method for use, and particularly a veterinary injector, is disclosed herein. One aspect of the present technology, for example, is directed toward a veterinary injector including a flexible container configured to house a medicament, a plunger configured to be slidably received within a lumen of the container, a needle, and a stabilizer at the distal portion of the container and configured to be grasped by a user. The stabilizer can include a first flap extending away from the hub in a first direction, a second flap extending away from the hub in a second direction, and a third flap extending away from the hub in a third direction.

A manual infusion set comprises a top connector lockable in a plurality of positions. The top connector and tubing is initially loaded from the top and then slid forward in order to puncture the septum. Once the connector is attached, it cannot be rotated. With the connector locked in place, flexible tubing connects the septum hub with a medicine pump, which continually supplies medicine such as insulin to a user.

A method, including the operations of molding a hollow cannula to create flash on the cannula at parting lines of a mold, retaining the flash on the cannula, and installing the cannula with the flash in a medical device.

The disclosed antimicrobial device securely attaches to an underlying substrate such that the insertion needle can puncture though the antimicrobial device for easy application and antimicrobial protection of the insertion needle. The antimicrobial device comprises a contact dressing with a contact dressing first surface and contact dressing second surface, opposite the contact dressing first surface. The contact dressing first surface has an adhesive and an antimicrobial agent. The insertion needle is inserted through the contact dressing. The adhesive and antimicrobial agent are on the contact dressing first surface adjacent the inserted insertion needle.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

An infusion device system includes a base (12) for removably coupling to a delivery device, a needle hub (22) supporting an insertion needle (20) and a catheter (18) for delivering a substance to a patient. The infusion device includes a needle shield (24) for covering the insertion needle (20) after inserting the catheter (18) into the patient. The needle hub (22) includes a least one leg (70) extending from the needle shield (24) to stabilize the needle shield (24) and needle hub (12) relative to the base. In one embodiment, the legs (70) can include a latching tab (74) to couple to the needle hub (22) to resist separation of the needle hub from the base (12) until the legs are deflected outward to release the needle hub (22).

An auto-retractable blood collection needle, including: a needle holder including a first tube, a second tube and a holder tail; a needle in stalled in the first tube; a built-in sliding sleeve which is elongated and through and has a C-shaped cross section; a needle shield which is hollow and elongated; and a spring sheathed on the first tube. The second tube is installed in the built-in sliding sleeve and is capable of sliding back and forth. The built-in sliding sleeve is installed in the needle shield and is capable of sliding back and forth. A locking mechanism is formed by the holder tail and the needle shield. When the holder tail is unlocked from the needle shield, a force of the spring pushes the second tube to slide backward, and then the built-in sliding sleeve is driven to slide rearward to lock with the needle shield.

An adhesive patch is secured to an infusion set, patch pump or other on-body medical device by an overmolding process during manufacture of the medical device, or during manufacture of a portion of the medical device, without the need for a separate adhesive. This provides a more secure connection between the patch and the medical device, and reduces the required number of adhesive layers from two (skin attachment side and device attachment side) to one (skin attachment side only), thereby simplifying the design and manufacture of the patch.

In accordance with yet another embodiment of the present disclosure an inserter assembly may comprise a housing. The inserter assembly may further comprise an infusion set having adhesive on a portion thereof for adhering the portion of the infusion set to skin. The inserter assembly may further comprise a sharp bearing body. The inserter assembly may further comprise a trigger. The inserter assembly may further comprise an insertion bias member held in an energy storing state by the trigger. The insertion bias member may urge the sharp bearing body from a raised state to a forward state when the trigger is released. The inserter assembly may further comprise a means for releasing the trigger after inserter assembly is withdrawn from the body and skin adhered to the portion of the infusion set has been lifted from underlying anatomy.
