Disclosed herein are several embodiments of a negative pressure appliance and methods of using the same in the treatment of wounds. Some embodiments are directed to improved fluidic connectors or suction adapters for connecting to a wound site, for example using softer, kink-free conformable suction adapters.

Apparatuses and methods for negative pressure wound therapy

A new and improved NPWT bandage which is simple, inexpensive, easy-to-use, small in size (including having a low profile), is atraumatic to the wound during use, has improved pump efficiency, incorporates an automatic pressure indicator for indicating the level of negative pressure created, and provides an automatic pressure limiter for limiting the level of negative pressure created.

A needle guard clip assembly has a clip and a spring, the clip having a first wall with a needle passage therethrough, a generally parallel second wall, a strut connecting the two walls, and a heel extending from the first wall. The walls, strut, and heel are an integral piece. The spring is associated with and extends from the first wall.

A coupling system for receiving a push rod includes a housing defining an internal channel having a sloped wall, and a piston received within the internal channel. The piston includes at least one flexible member arranged within the channel to be acted upon by the sloped wall to engage the push rod. The only external force required to couple the push rod is an axial force on the piston in a direction. The only external force required to de-couple the push rod is an axial force on the piston in an opposite direction.

Disposable pumping system and coupler

A needle guard includes a clip with a canting wall to grip the needle shaft and a distal wall to block the tip thereof, wherein the canting and distal walls may be interconnected by an angled strut, a spring member, such as a leaf spring, may have a portion extending past an edge of the strut to bias the clip to grip the needle shaft, and the distal wall may be or include a stylus and have an L-shape to define a lip to help block the needle tip. The clip may have a depending heel to help pivot the clip about a ledge to grip the needle shaft. A needle support may be provided to limit flexure of the needle which might otherwise allow the needle to come loose from the clip. Arrangements for limiting rotation of the needle hub and needle guard housing are provided, as is a protective shroud to reduce the risk of inadvertent activation of the needle guard. Further, the needle guard may be used with a catheter assembly. Also provided is an improved duckbill release mechanism.
