    摘要： The present disclosure relates to a tracheostomy exchange system including a catheter comprising a distal end and a proximal end, a balloon fluidly coupled to the distal end of the catheter, and an adapter assembly removably coupleable to the catheter and configured to fluidly couple the balloon with the proximal end of the catheter when the adapter assembly is coupled to the catheter. When the adapter assembly is decoupled from the catheter, the balloon is fluidly sealed from the proximal end of the catheter. When the is inflated before the adapter assembly is decoupled from the catheter, the balloon can remain inflated while the tracheostomy is exchanged preventing aerosolization, protecting the lungs from bleeding and aspiration, allowing for effective oxygenation while preserving an access to the main airway.

    摘要： An oxygenator includes: a housing; a bubble-removing hollow fiber membrane layer removing a bubble; a gas-exchanging hollow fiber membrane layer exchanging a gas with blood; and a discharge port to discharge the bubble removed by the bubble-removing hollow fiber membrane layer to the outside of the housing. The oxygenator further includes a gas permeable portion that is arranged between the discharge port and an end portion of the bubble-removing hollow fiber membrane layer, is formed by a member having gas permeability, and allows passage of the bubble removed by the bubble-removing hollow fiber membrane layer without allowing passage of plasma leaking through the bubble-removing hollow fiber membrane layer. A plasma capture chamber that captures the plasma leaking through the bubble-removing hollow fiber membrane layer is formed between the end portion of the bubble-removing hollow fiber membrane layer and the gas permeable portion.

    摘要： Device having a reservoir containing a dose of powder, a head having an orifice, an actuating member displaceable with respect to the head, and an air vent generating a flow of compressed air for delivering the dose of powder into the nostril through the orifice. The air vent has a chamber, formed by a cylinder, and a piston which slides sealingly within the cylinder in order to compress the air contained in the chamber. The device has an insert forming the piston and interacting sealingly, in a rest position, with the reservoir, the insert being axially displaceable with respect to the reservoir between its rest position and an actuation position, in which it no longer interacts sealingly with the reservoir.

    摘要： A surgical instrument has a hollow tubular member, and a pressurization unit that has an outer valve portion, a pressurization device having a movable part configured to generate pressurized fluid when the movable part is moved, and an inner valve portion. The inner valve portion includes a first flow passage that is configured to fluidically connect a first port and a second port of the outer valve portion to each other when the inner valve portion is in a first position, and a second flow passage that is configured between the inner valve portion and the outer valve portion to fluidically connect the first port and a third port when the inner valve portion is in a second position. A sealing system fluidically isolates the second port and the third port from each other at any position of the inner valve portion. Pressurized fluid from the pressurization device causes the inner valve portion to move from the first position to the second position, thereby providing positive pressure to the hollow tubular member.
