Abstract: To provide a liquid medicine self-injection system that enables patient himself/herself to easily and safely inject (in particular, bolus-infuse) a prescribed amount of liquid medicine for preventing, treating or improving obstetrical pain, in particular, for a painless childbirth. The liquid medicine self-injection system according to the present invention contains a liquid medicine preservation container for storing a liquid medicine, a liquid medicine feeding-out means for feeding out the liquid medicine from the liquid medicine preservation container, and a liquid medicine injection device for allowing the liquid medicine fed out from the liquid medicine preservation container to be self-injected, and is configured to be able to use for preventing, treating or improving obstetrical pain, in particular, for a painless childbirth.

Abstract: In the transplant of a living organism tissue, such as a heart valve, taken from an animal, etc. into a human body, a cell removing solution for removing original cells from the living organism tissue is provided with flow approximately equal to the bloodstream of transplant recipient living body, and the living organism tissue is placed in the flow so as to effect immersion of the living organism tissue in the cell removing solution. In the immersion, it is preferred that the living organism tissue placed in the cell removing solution, while being rotated, be irradiated with microwave. As a result, original cells can be removed from the living organism tissue uniformly and reliably, so that the biocompatibility of living organism tissue after transplant can be enhanced.

Abstract: An applicator suitable for applying various powders and liquids in the fields of cosmetics, writing, painting, and medical treatment etc, which is particularly preferred as a make-up instrument such as a chip or a brush for applying eye shadow, and to a method of producing the applicator. The applicator has one or two coating parts obtained by grinding the peripheral part of either or both ends of an applicator main body which is made by bonding a fiber bundle with a synthetic resin solution, and a holding part being the unground middle part of the applicator main body, wherein the applicator main body impregnated with the resin solution is dried by hot air and the solvent in the resin solution is removed, thereby the resin is unevenly distributed and exists more in the peripheral part, and the peripheral part becomes harder than the central part.

Abstract: A flow control device has a body (41), a plurality of elastic flow control tube (51-54) provided in the body (41), a single fluid path (55) in communication with the flow control tube (51-54), a slider (56) slidable relative to the body (41), and a valve mechanism (71) for selectively pressing and shutting the flow control tube (51-54) in accordance with a slide position of the slider (56).

Abstract: A fluid supplying apparatus having a rubber elastic film (11) with fluid contained therein, an upstream tube (30), an intermediate station (40) disposed at a distal end of the upstream tube (30) and a downstream tube (27) connected to the intermediate station (40) is provided. The upstream tube (30) has two flow paths (31A and 32A) formed in a predetermined length extending in a longitudinal direction. The intermediate station (40) has a case (41), the case (41) having a fluid outlet (51) to which the downstream tube (27) is connected, a first communicating channel (52) for intercommunicating the fluid outlet (51) and one of the flow paths (31A), a reservoir (53) in communication with the other flow path (32A), a second communicating channel (55) having a check valve (54) at an intermediate portion thereof and intercommunicating the reservoir (53) and the fluid outlet (51), and a pressing member (56) for discharging the fluid stored in the reservoir (53) to the second communicating channel (55).

Abstract: A hemoglobin sampler for use with stool samples for clinical tests and diagnoses of the digestive tract diseases in mass screening, etc. by securely sampling and collecting occult hemoglobin with water content from the stool samples without being hindered by the undigested solid content of stools. The sampler has a core member consisting of a porous fiber bundle made up of a plural number of synthetic fibers bundled in the longitudinal direction thereof, a rod of a suitable length provided with a thermosetting synthetic resin sheath at the outer periphery of the core, one end of the rod forming a sample absorbing member with a suitable surface area and small diameter made up of the above mentioned porous fiber bundle. The sampler can quantitatively sample occult hemoglobin with water from stool samples of various properties, thereby offering an easy sample method for the subject and stable specimen for tests.

Abstract: A liquid medicine injecting device for constantly feeding a liquid medicine into a human body at a certain degree. The liquid medicine stored in a liquid medicine receiving portion is fed out therefrom by a pressure means to be supplied into the human body through a flow amount control means and a human body fitting tool such as a needle. Even if there are contaminant and the like in the liquid medicine or if the flow amount control means is folded, twisted, or pressured, the tube is not blocked up to thereby function as a capillary tube and a member for controlling flow amount with a simple structure so that a high productivity and a easy handling can be obtained.

Abstract: Flexible pen nib (20) for writing instruments includes a rod-like nib body having inner capillary channels (24) for passing ink therethrough. This nib body is a porous rubber-like elastic body having composite-fiber textures obtained by combining a number of longitudinally oriented crimped polyamide fibers (21), with synthetic resin elastomer (22). Those composite-fiber textures form, within the cross-section of the pen nib, random-shaped elements (23) which are arranged in a uniformly random aggregation leaving the capillary channels (24). The capillary channels (24) have an orientation in the axial direction of the pen nib, and provide the pen nib with a predetermined porosity.

Abstract: Thermoplastic synthetic resin pen nib is disclosed, which may suitably be employed in writing instruments for fine lettering or for drawing fine lines. The pen nib is formed of thermoplastic crystalline synthetic resin, e.g. polyethylene terephthalate resin, whose molecules are in a specific mixed cystallization structure obtained by controlling the crystallization. This structure consists essentially of molecularly oriented crystals, non-oriented fine crystals dispersed and grown between the oriented crystals, and remaining amorphous regions, and provides the pen nib with highly improved physical and chemical properties.

Abstract: Method of manufacturing synthetic resin pen nibs is disclosed, which pen nibs may suitably be employed in writing instruments for fine lettering or drawing fine lines. The pen nibs are formed of thermoplastic crystalline synthetic resin, e.g. polyethylene terephthalate resin, which is extruded from a molding die and subjected to rapid cooling to form a continuous rod in amorphous state. The rod is axially stretched under predetermined temperature condition to achieve oriented crystallization of the resin molecules, and is further heat-treated such that non-oriented fine crystals are dispersed and grown between oriented crystals and remaining amorphous regions. Pen nib thus obtained has highly improved physical and chemical properties.
