    摘要： A weight-actuated vacuum pump for a hypobarically-controlled artificial limb having a socket with a cavity to receive a residual limb. A dual-action pump has a housing fixedly attached to the socket of the artificial limb, a cylinder reciprocating within the housing and attached to the pylon of the artificial limb, a first chamber within the cylinder, a piston reciprocating within the first chamber, a second chamber between the cylinder and the housing, and valves for connecting the first chamber and second chamber to the cavity and to atmosphere. A single-action pump has a housing fixedly attached to the pylon of the artificial limb with a first chamber therein, a piston reciprocating in the first chamber with a seal, forming a second chamber between the piston and the housing, an intake/exhaust port connected to the second chamber, and one-way valves connecting the second chamber to the cavity and to atmosphere. Ambulation causes the vacuum pump, under the influence of the wearer's body weight, to draw air out of the cavity, producing a vacuum within the cavity.

    摘要： An absorbent article which comprises an absorbent element which at least partially comprises an absorbent sheet A prepared by applying a pressure-sensitive adhesive 3 having a suitable adhesive power to an absorbent material 1 having a suitable liquid-absorbent (or retentive) power in the form of dot, line or curve (spiral curve or the like) with the pressure-sensitive adhesive in a suitable density; spreading an absorbent polymer 2 thereon; putting another sheet of the absorbent material 1 thereon, and compressing the assemblage into a composite structure. In the course of the absorption of a liquid, the liquid is first stocked in the absorbent material having a high initial absorption velocity, and is gradually transferred to the absorbent polymer by capillary power as the driving force and absorbed therein, while the absorbent polymer is prevented from falling off from the absorbent material by the pressure-sensitive adhesive, whereby the properties of the absorbent polymer can be exhibited to the fullest.
