Abstract: Provided is a method for peeling a PSA sheet adhered on a polarizing plate. The PSA sheet has a PSA layer. The PSA layer includes a layer A forming at least one surface of the PSA layer. Of the polarizing plate, the surface to which the PSA sheet is adhered is corona-treated or plasma-treated. The peeling method includes a water-peel step in which the PSA sheet is peeled from the polarizing plate, in a state where an aqueous liquid exits at the interface between the polarizing plate and the PSA sheet at the front line of peeling the PSA sheet from the polarizing plate, with the aqueous liquid allowed to further enter the interface following the movement of the peel front line.

Abstract: A battery monitoring device includes: a pair of terminals for measuring voltage or current of a battery, and to which a filter unit including a capacitive element is connected; an AD converter that measures a waveform of voltage between the terminals during charging or discharging of the capacitive element; and a time constant calculation unit that calculates a time constant of the filter unit based on the waveform measured. The AD converter is, for example, a first AD converter or a second AD converter. The filter unit is, for example, a first filter unit or a second filter unit.

Abstract: A method for producing a polyurethane foam includes mixing and reacting a polyurethane foam raw material containing a polyol, an isocyanate, a foaming agent, and a catalyst, wherein the polyurethane foam raw material contains sodium bicarbonate and an organic solid acid such as citric acid or malic acid.

Abstract: The invention provides a dilator having characteristics as an inexpensive instrument that allows insertion of a guidewire for assisting insertion of a catheter into a vessel in a simple and smooth manner. A first through-hole 5 into which a guidewire can be inserted is pierced over an entire region of a dilator 1 from a distal end face 3a to a rear end face 3b in the longitudinal direction of the dilator. A second through-hole 7 into which a guidewire can be inserted is pierced over a region of the dilator 1 from a midway to the rear end face 3b in the longitudinal direction of the dilator. A tapered portion 9 is formed such that it is tapered toward the distal end face 3a. An opening 7a a of the second through-hole 7 is open on the surface of the tapered portion 9.

Abstract: A catheter a part which is inserted into and indwelled in a blood vessel by the Seldinger method and a sheath for covering the catheter are included. The catheter is constituted of a double lumen portion in which a first lumen and a second lumen are integrally formed in parallel with each other, a first branch tube and a second branch tube extended to the one side of the double lumen portion and an extension tube connecting portion provided to the other side of the double lumen portion. The inner cavity of the first branch tube communicates with the first lumen and the inner cavity of the second branch tube communicates with the second lumen. The distal end of the first branch tube is bulged in the vicinity thereof so as to slidably contact with the inside of the distal end of the sheath.

Abstract: A catheter including a tubular body having a distal end, and a tubular tip portion extending contiguously from the distal end substantially coaxially therewith and terminating in a forward facing aperture, wherein the tubular tip portion is formed of a water-absorbing, water-swelling material.

Abstract: A suction catheter is disclosed having a tubular, bellowed flexible proximal or patient contacting end creating a rigidity to not permit bending and twisting during the catheter's insertion and operation, a flexibility to prevent injuring a patient's trachea or bronchial tube and having a good suction efficiency. A lumen leads to openings in the catheter made at the bellowed proximal end that fluidly connects the lumen with the exterior of the catheter.

Abstract: A method of manufacture of a fiberscopic catheter having a tightly fitted optical glass fiber bundle received within an internal lumen of the catheter. The lumen for receiving the optical glass fiber bundle is heated and expanded under internal fluid pressure. The catheter and lumen are then cooled with the lumen still under the internal fluid pressure. After cooling, the fluid pressure is released and the lumen retains its expanded condition. An optical glass fiber bundle is inserted into the expanded lumen to a predetermined position within the catheter. The catheter and lumen are reheated to contract the expanded diameter of the lumen about the optical glass fiber bundle to provide a fiberscopic catheter having a tightly fitted fiber optic bundle within the catheter.

Abstract: A double lumen gastric tube including a valve to prevent gastric reflux or leakage through the vent lumen thereof. The gastric tube also includes an adaptor which allows fluid injection through the tube without removing the valve. The valve allows the passage of air into the vent lumen when atmospheric pressure exceeds stomach pressure. When stomach pressure exceeds atmospheric pressure the valve prevents flow of fluid through the tube. The adaptor allows fluid to be injected into the vent lumen through the valve.

Abstract: A hemostasis valve membrane for use with a catheter introducer having a cover and a frame is disclosed. The valve membrane is inserted between the cover and the frame of the catheter introducer body. The valve membrane is a disc made of a soft elastic material. The disc has opposed faces, at least one of which has a concave shape extending into the disc. A plurality of slits extend into the disc from the faces so that slits extending into the disc from one face do not touch slits extending into the disc from the opposed face. A needle hole connects the slits extending into the disc from one face with the slits extending into the disc from the opposed face.

Abstract: This invention provides a catheter for nasogastric intubation comprises a tube for nasogastric intubation and a plastic separator, said tube for nasogastric intubation consisting of a catheter and a plastic sheath tube having a longitudinal tear-off line over full length thereof together with elasticity and rigidity slightly larger than those of said catheter inserted slidably thereinto, and said separator for splitting said sheath tube fixing said tube at the vicinity of a nostril.

Abstract: The present invention provides a catheter for nasogastric intubation comprising a plastic sheath tube and a fixing means of said tube at nose, said tube having a longitudinal tear-off line over the full length thereof and having elasticity and rigidity slightly larger than those of said catheter, said catheter being inserted entirely in said plastic sheath tube slidably.

Abstract: The present invention a catheter obturator including a stopper having a bore formed therethrough, a tube of resilient material connected at one end with the stopper to communicate with the bore in the stopper, the opposite end of the tube being closed, and manipulating means including a rigid rod adapted to be inserted into the tube, whereby when the rigid rod is moved forwardly in the tube, the latter can be elongated to facilitate the insertion of the tube into a catheter while when the rigid rod is removed out of the tube, the latter tends to return to its original form to fully close the internal bore of the catheter.

Abstract: The present invention provides a catheter assembly for placement in a blood vessel which comprises a catheter body having an opening at the distal tip thereof and provided with a luer-connector at proximal portion and a flexible guide wire inserted into said catheter body and bendingly formed to be J-shaped at the distal tip thereof.
