A compression device includes: an adhesive sheet having an adhesion surface; and a compression member. The compression member includes: a pressing body configured to press a biological surface; and a holding body fixed to the adhesive sheet and configured to hold the pressing body to be extendable. The pressing body includes: an inflatable portion that is inflatable; and an extending portion extending from the inflatable portion and wound around the holding body to extend from the inflatable portion to an upper surface side of the holding body with the holding body interposed therebetween. The extending portion includes a light-transmitting portion having translucency in the thickness direction at a position covering an upper surface of the holding body. The holding body includes, at a position overlapping with the light-transmitting portion of the extending portion in a plan view, a marker portion configured to be visually identified.

A system for strain relieving intravenous (IV) assembly includes a dressing and an anchor portion for use with the dressing. In various embodiments, the dressing may cover an injection site into a portion of a patient's body for an intravenous (IV) assembly that provides fluid communication between the injection site and a fluid reservoir remote from the injection site through a flexible tube. In an illustrative example, the anchor portion may include a first member and a second member. The first member may be secured, for example, to the dressing and may, in some examples, wrap around the tubing so as to resist axial movement of the tubing relative to the dressing. The second member may be secured to the dressing and may wrap around the tubing and a portion of the patient's body so as to resist radial movement of the tubing relative to the body.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

A system for providing the collection of advanced, improved, and novel new components and elements in a single package to simplify assembly and use of the infusion set by the user, including one or more of an exemplary pushbutton-type inserter, squeeze-type inserter, contact-type inserter, skin pinching-type inserter, folding retraction-type inserter, and/or multistage-type inserter (700) having at least one reusable stage, an exemplary set (350) having an adhesion means with two or more user-selectable degrees of adhesion strength, a self-sealing tube connection means, a lens feature to view a site beneath the set, exemplary tube management and connection elements (450), insulin supply (475), adhesion concealment means (500), finger loops on the inserter and site preparation wipes or sprays (550) which can be provided as part of the inserter. The system can further include an exemplary package (12) which can hold a number of sets that can be easily released and retrieved from the tray by an inserter, an exemplary insertion needle handle and shroud, an exemplary squeeze-type latch between an upper portion and a lower portion of the set, and/or a tool removable upper portion of the set.

Systems and methods for automatic intravenous injection in accordance with embodiments of the invention are illustrated. One embodiment includes a method for automatically injecting a needle into a vein. The method includes steps for identifying an injection position using a first set of one or more sensors, positioning an injection mechanism at the identified injection position, and vertically inserting a needle until entry in a vein is detected using a second set of one or more sensors.

This invention relates to a catheter cover. Previously, catheter covers that may protect a catheter from water were not efficiently securable to a human user. Embodiments of the present invention use a tab (50) joined to a sleeve on the catheter cover. A first adhesive strip (52) is joined to the tab and the sleeve and is configured to be attached to skin of a human user.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user's body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user's outer skin layer. The system further may include an applicator for inserting the cannula into the user's skin and/or applying an adhesive pad to the skin.

Devices, kits and methods described herein are be used at chronic injection site or in conjunction with an indwelling catheter or cannula. A book-like packaging, applicator and/or tensioning device with an opening and optional indicia to align the catheter or cannula to the opening may be used to apply a dressing to a subject. The packaging, applicator and/or tensioning device may apply and/or maintain a strain in an elastic dressing.
