Disclosed is a tube connector for medical treatment including a housing including an internal channel configured to allow an inflow pipe disposed at the front end thereof and an outflow pipe disposed at the rear end thereof to fluidly communicate with each other, an insertion hole formed from the outer surface of the rear end of the housing to the internal channel, and at least one branch pipe disposed so as to fluidly communicate with the internal channel, a push button having a through hole, the push button being disposed in the insertion hole so as to be movable upwards and downwards, and an elastically deformable dome-shaped balloon configured to surround the insertion hole of the housing, the lower part of the balloon being open, wherein the internal channel of the housing is opened and closed through the upward and downward movement of the push button.

A splittable sheath includes a splittable sheath body, a splittable sheath hub, and a valve element. The sheath body comprises a generally flexible tubular structure, a proximal end, and a distal end. The sheath body defines a longitudinal axis and is splittable into two halves along a pre-determined line generally parallel to the longitudinal axis. The sheath hub extends from the proximal end of the sheath body and defines a longitudinal axis generally aligned with the longitudinal axis of the sheath body. The sheath body and sheath hub form an inner cavity along their respective longitudinal axes. The valve element includes a resilient plate and a sealing element. The resilient plate includes a distal portion extending radially inwardly from a side of the inner cavity. The sealing element includes a sealing surface and is supported by the resilient plate such that the sealing element is biased toward a position against a second sealing surface on at least one of the splittable sheath body and hub to substantially seal the inner cavity.

Aspects include systems having an intravenous fluid bag, a tubing line assembly including tubing connected to a connector and a purge valve assembly including a spike and an outer housing. The outer housing is connected to the spike and includes a receiving end portion configured to receive the connector. The purge valve assembly further has a check valve provided within the outer housing. Generally, the purge valve assembly interconnects the fluid bag to the fluid tubing assembly for removal of air from the fluid bag prior to connection to the tubing line assembly. Various methods and purge valve assemblies provide a rapid infusion system for use. The purge valve assemblies do not require the user to reinsert the connector or spike into the intravenous fluid bag, creating a sterile solution to preparing the intravenous fluid for rapid infusion while reducing the risk of air emboli.

Methods and devices for accurately pumping small quantities of liquid to a patient with a broad range of flow and low cost.

A wound irrigation system and method of making and using. The system uses a pored, closed-ended delivery conduit to enhance the consistency and speed with which anti-microbial or related irrigation fluids may be delivered in order to promote cleansing, debridement and biofilm reduction in wounds. The ease of use of the system as a moist wound healing cascade makes it applicable to both in-home and in-facility environments that is not offered through traditional instillation negative pressure systems. In one form, the fluid delivery conduit is used as part of a dual-conduit approach in order to also help promote the removal of drainage, waste, irrigation overflow or other fluid from the wound. Utilization of such a pored, closed-ended delivery conduit in conjunction with a separate drainage conduit infusing helps reduce the frequency of dressing changes as well as the likelihood of microorganism formation and colonization.

A drainage liquid sampling system is disclosed and includes a connector couplable with a drainage tube of a drainage system, the connector defining an inlet port, an outlet port, and a sample port, where the inlet port, the outlet port, and the sample port are in fluid communication with each other, and a sample container couplable with the sample port. A valve within the connector selectively allows and prevents flow of drainage liquid into the sample container. A cap couplable to the sample container also includes a valve. A system for draining liquid from a patient includes the drainage liquid sampling system.

A dental valve device has a valve body having a tip receiving end having a flexible tubing extending outwardly from the tip receiving end with the flexible tubing having a flexible tubing opening, a hose receiving end, a lumen formed between the flexible tubing opening and the hose receiving end, and a partial opening formed in the valve body, and a rotatable valve sealing body adapted to be inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the flexible tubing opening and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening.

Methods and devices for accurately pumping small quantities of liquid to a patient with a broad range of flow and low cost.

New shape memory polymer compositions, methods for synthesizing new shape memory polymers, and apparatus comprising an actuator and a shape memory polymer wherein the shape memory polymer comprises at least a portion of the actuator. A shape memory polymer comprising a polymer composition which physically forms a network structure wherein the polymer composition has shape-memory behavior and can be formed into a permanent primary shape, re-formed into a stable secondary shape, and controllably actuated to recover the permanent primary shape. Polymers have optimal aliphatic network structures due to minimization of dangling Chains by using monomers that are symmetrical and that have matching amine and hydroxl groups providing polymers and polymer foams with clarity, tight (narrow temperature range) single transitions, and high shape recovery and recovery force that are especially useful for implanting in the human body.

The present disclosure relates to a subcutaneous fixation system for fixing medical devices, in particular catheters, and keeping them in position with respect to an access point on the skin of a patient.
