Abstract: A drape for clean operation is a flexible bag-shaped structure for maintaining a substantially closed operating space around an operation site. The bag-shaped structure comprises a bottom wall 1 and a transparent top wall 2 and has a closed proximal end 100a and a closed distal end 100b. The bottom wall 1 is provided with at least one operation site-revealing opening 3 close to the proximal end, and the top wall 2 is provided with at least one pair of hand insertion parts 4 at a position close to the operation site-revealing opening 3 to allow the physician to aseptically insert the hands into the operating space, and a closed, openable and closable medical device supply port 5 for supplying medical devices required for operations at a position away from the operation site-revealing opening 3.

Abstract: A balloon catheter which is good in cross ability and is also good in gripping property so as not to cause slipping during kissing technique includes a tubular body having a balloon 3provided in a distal section 12 of a shaft 1, the shaft 1 being flexible in the distal section 12 and stiff on its proximal side, whereby gripping property and cross ability are adjusted with good balance. Specifically, the gripping property is adjusted to 3.2 N to 6.0 N, and the cross ability is adjusted so that its initial value is not higher than 0.65 N and its middle value is 0.40 N.

Abstract: A suction-type blood sampler has a housing (1), a lancet unit (2) having a rod (4) extending backward from the lancet unit, and a plunger (3) connected to the rod in the housing and having a seal (7) attached to a forward end of the plunger. The seal is in sliding airtight contact with an inner periphery of the housing. The lancet unit consists of a lancet body (11) having a forwardly extending needle (12) and held by a lancet retainer (18) which is in sliding contact with the inner periphery. The blood sampler further has first, second and third springs (8, 9, 10) placed between the lancet unit and the plunger. The second spring urges the lancet unit to project the needle forwards, and the third spring tends to retract it. The first spring acts to reduce air pressure in the housing when the plunger is released.

Abstract: A trocar assembly includes a cannula, a trocar needle fitted in a lumen of the cannula, a cannula-retaining member having a through-hole for inserting the cannula therein and being provided at a bottom thereof with an adhesive layer for fixing the cannula in place on the skin of a patient. The cannula is adapted to be held in the retaining member by engaging elements between them to permit the cannula to move forward continuously or continually through the through-hole of the retaining member as well as to fix the cannula in a desired position.

Abstract: A device for forming an inserting hole comprising at least two tubes having different outer diameters, and at least one of a guide wire and a sticking needle. A largest diameter tube has at its thick-walled end at least one longitudinal and approximately linear tearing line. The largest diameter tube, after being inserted into the body, can be torn using the tearing line and fixed to the skin of a patient by sewing a folded portion of the tube on the skin. The tube is not moved by the breathing or pressure since it is fixed to the skin. When the tearing line is formed by an ultrasonic cutter, width of the tearing line can be made narrow thereby preventing adhesion of bacteria to a cut portion and unexpected opening of the tearing line in the body.

Abstract: A microphone output transmission circuit for a capactive microphone such as an electret microphone employs a differential amplifier to provide a transformerless balanced connection to a microphone transmission line, either at the transmission end or at the reception end thereof. Power is applied in a phantom connection by superimposing a DC voltage on two balanced signal conductors of the transmission line, and using the shield thereof as a ground return line. A pair of microphones with oppositely-directed sound-gathering planes can be connected to respective inputs of a differential amplifier at the transmission end, so that the two microphones together have a bidirectional characteristic.

Abstract: A multiple magnetoresistance element includes a first stripe group and a second stripe group which comprise a plurality of stripes electrically connected in series with each other and spaced from each other by a predetermined distance. The stripes are made of ferromagnetic material having an anisotropic effect of magnetoresistance and have a plurality of main current path portions.The first stripe group and the second stripe group are electrically connected to each other and spaced from each other by a predetermined distance. An output terminal is connected to a connecting point of the first stripe group and the second stripe group. Current supply terminals are connected to ends of the first stripe group and the second stripe group.
