Abstract: The present invention provides a fluorine-containing ether compound represented by the following Formula. R1-[B]-[A]-CH2—R2—CH2-[C]-[D]-R3 (R2 is a perfluoropolyether chain; [A] is Formula (2-1); [B] is Formula (2-2); [C] is Formula (3-1); [D] is Formula (3-2); R3 is Formula (4); and R1 is a terminal group.

Abstract: An object of the present invention is to provide a revolutionary suture needle of exceptionally high marketability. The suture needle curves in the lengthwise direction of the needle body. A curved inner surface portion extending from a needle distal end (3) to a predetermined position P1 towards the basal end of a distal end portion (2) of circular cross section is furnished with frictional resistance reducing means for reducing the frictional resistance to less than that of a curved outer surface portion from the needle distal end (3) to the predetermined position P1 towards the basal end. The frictional resistance reducing means is a chamfered portion (4) chamfered at a surface passing through the needle distal end (3). The needle distal end (3) is furnished at a position coincident with the center axis L of the needle body (1).

Abstract: The present invention addresses the problem of providing an innovative suture needle which exhibits unprecedented effects. An uneven part is provided to left and right side parts of a distal end site of a needle body (1), and edge parts of the uneven part are configured as small blades (6, 7).

Abstract: A cranial treatment apparatus has a head portion arrangement body for arranging around a head, a retainer member retained at each cranial piece being tensed by a tension maintenance member for maintaining a tensed condition so that cranial pieces are tensed in a direction away from each other. The retainer member is provided in the head portion arrangement body.

Abstract: An air mattress is provided having an improved internal construction for supporting a patient. The mattress provides an internal ventilation system for controlling environmental conditions present at the patient mattress interface. The air mattress contains a plurality of pneumatic envelopes disposed adjacent each other. Located between the envelopes are ventilation conduits having a plurality of exhaust ports. Sequentially alternating envelopes are coupled to a fluid supply line which in turn is coupled to a source of compressed air. At predetermined intervals, a first set of envelopes is inflated while adjacent envelopes are deflated, and vice versa, shifting support for the patient to different areas of the body. Each envelope has two vertically disposed chambers. These preferably are provided lateral support by upright, lateral elastic members straddling the envelope. Ventilating air may be provided by an air conditioning system to a manifold for distribution to the several ventilation conduits.

Abstract: A device for securing detachably a filtering sheet to an air bed, which includes a bed body, having an upper peripheral edge defining an opening, and a number of fine solid particles contained in the bed body, has a flange secured to the upper peripheral edge of the bed body, a hook tape secured to an upper surface of the flange, a loop tape secured to a lower surface of a periphery of the filtering sheet, and a cover resiliently clamped on the flange. The filtering sheet can be firmly secured in an airtight manner to the flange in an easily removable manner by engagement between the hook tape and the loop tape.

Abstract: An apparatus for connecting a thread wound on a bobbin to a surgical needle including feeding rollers for unwinding the thread from the bobbin, a tube-like chuck for selectively fix the thread thereto, a guide for guiding the front end of the thread, a feeding device for supporting the needle such that a hole formed in a rear end face of the needle is faced to the front end of the thread, and a clamping device having pushing rods for pressing the rear end of the needle to clamp the thread in the hole. By moving the needle to the guide, the front end of the thread is inserted into the hole of the needle, and then the clamping device is driven to press the rear end of the needle so that the thread is clamped in the hole. Then, the thread is unwound from the bobbin by a desired length by moving the feeding device away from the guide, and finally the thread is cut along an inclined line.

Abstract: A protector for a surgical knife having an edge portion and a stem portion is disclosed. The protector is formed by a mold of synthetic resin and comprises a base plate having a peripheral shape substantially corresponding to a peripheral configuration of the edge portion of the knife, an upright ridge formed along a periphery of the base plate except for a portion through which the stem portion of the knife fit in the protector extends, and at least one projection formed on the base plate at a position at which a hole formed in the stem portion of the knife situates upon fitting the knife in the protector.
