An introducer sheath is disclosed, which includes a tube body that is percutaneously inserted into a body lumen; and a hub that is connected to a proximal portion of the tube body. The tube body contains a polyvinylidene fluoride resin, a ratio of a thickness to an inner diameter of the tube body is 1/16 or lower, and a ration of a kink radius to an outer diameter of the tube body is 9.5 or lower.

A fluid-management system for selectively draining fluid from a body cavity includes a valve assembly and a tube for carrying fluid from a body cavity of a person to the valve assembly. The valve assembly is configured to be positioned external to the person's body and comprises (i) an inlet, (ii) an outlet, (iii) a pumping chamber between the inlet and outlet and configured to be compressed and decompressed to pump fluid, (iv) a first one-way valve positioned on a first side of the pumping chamber, (v) a second one-way valve positioned on a second side of the pumping chamber, and (vi) an adjustable inlet lock configured to selectively prevent fluid movement through the inlet, and wherein the tube is configured to extend from the inlet of the valve assembly to the person's body cavity.

A cannula ingress system may include a tip stabilization mechanism having a tip stabilization mechanism distal end and a tip stabilization mechanism proximal end, a fixation mechanism, a hypodermic tube having a hypodermic tube distal end and a hypos dermic tube proximal end, and a tip having a tip distal end and a tip proximal end. The tip may be disposed within the hypodermic tube wherein the tip distal end extends from the hypodermic tube distal end. The fixation mechanism may be disposed within a fixation mechanism channel of the tip stabilization mechanism. The tip stabilization mechanism may be disposed over the tip and the hypodermic tube distal end.

A medical connector of the present invention is characterized in that: when a male connector portion is inserted into a female connector portion, a first locking portion is engaged with the female connector portion to achieve a first locked state as well as a second locked state; when the second locked state is released by operation of a second unlock operating portion and the female connector portion is moved in a disengagement direction with respect to the male connector portion, the locking member is moved in the disengagement direction together with the female connector portion while keeping the first locked state; and when the female connector portion is rotated with respect to the male connector portion, the first locked state is released.

A breast milk collection device includes a reservoir volume and an adaptor having one end to receive a woman's breast. The adaptor has a drip tube communicating with the reservoir. A source of cyclical application and relief of vacuum force is applied to the woman's breast located in the adaptor for the expression of breast milk. A one-way assembly permits breast milk to enter the reservoir and to submerge the valve element. The valve assembly includes a flexible barrier having an interior hollow chamber in fluid communication with said cyclical source of vacuum force and relief pressure, the flexible barrier fluidly isolating the source from the reservoir. The flexible barrier inflatably expands when relief pressure is applied to the interior of the flexible barrier, the flexible barrier becoming deflated when a vacuum force is applied to the hollow interior of the flexible barrier.

A hemostatic device has a band for being wrapped around a puncture site P of a wrist W, securing means for securing the band in a state where the band is wrapped around the wrist, an inflation portion that interlocks with the band, and that is inflated by injecting gas, and an injection portion that can inject gas into the inflation portion. The injection portion is disposed in the band, and is foldable so as to decrease a space formed inside the injection portion. The hemostatic device can thus inflate an inflation portion without using a separate dedicated instrument, which can prevent a hemostasis-requiring site from being unintentionally compressed more than necessary.

A pumping system comprising a pump comprising a door for access within a housing of the pump, a pump segment configured for conveying a fluid based on compression of the pump segment, a pump segment frame for preventing said pump segment from stretching, a visual placement indicator configured for facilitating in a proper placement of the pump segment frame in the housing, and a non-pinching valve configured to be disposed in the housing and to control a flow of the fluid without requiring pinching of a tube.
