Abstract: An indicator for a cuffed medical device, attached to a cuffed medical device to indicate internal pressure in a cuff of the medical device. The indicator includes: an indicator main body which includes a check valve adapted to be connected to an injection means for injecting a fluid into the cuff, a connecting section formed integrally with the indicator main body for connecting to the cuffed medical device, the connecting section communicating with the inside of the cuff, and a communication path for making the check valve and the connecting section communicate with each other; and a balloon provided in the indicator main body. The inside of the balloon is made to communicate with the communication path and is inflatable and deflatable in accordance with the internal pressure in the cuff.

Abstract: The magnetic tape guiding cylinder device includes a rotatable upper cylinder; a fixed lower cylinder opposed to the upper cylinder and having a cylindrical member integrally formed with and penetrating through a bottom plate at one end of the lower cylinder which is remoter from the upper cylinder, the cylindrical member being provided with bearings at both axial end portions; a drive shaft rotatably supported by the lower cylinder via the bearings to drive the upper cylinder, the cylindrical member being grasped by a chuck during finishing operation of the lower cylinder. The device is particularly characterized in that the cylindrical member is formed with a circular groove along the outer circumference between the bottom plate and one of the axial end portions which is remoter from the upper cylinder.

Abstract: A device for preventing the observing objective lens window of an endoscope from collecting moisture by directing a small flow of air over the front surface of the observing objective lens window to form a layer of air which has the same temperature as the ambient atmosphere thereby stabilizing the temperature of the window. A control valve is provided which shuts off the flow of air in the event that the pressure within the body cavity in which the endoscope is inserted becomes too high due to the flow of air. A first embodiment of the control valve includes a cylinder and piston arrangement in which at a first position of the piston air is allowed to flow through the tube to the endoscope end. At a second position of the piston, air is vented directly to the atmosphere. In a second embodiment, a lateral hole is provided in the piston with the area of the hole and hence flow of air controlled by a screw the position of which determines the area of the lateral aperture.

Abstract: A device for changing a direction of the top end part of an endoscope in which a manual operating section is coupled to a top end part curving section through wires and the top end part curving section is curved vertically and horizontally by pulling the wires. A pair of wires are adapted to drive the top end part curving section vertically and horizontally, respectively, and a pair of drive members pull the wires directly or through intermediate members. Rotating knobs are integrally coupled to the pair of drive members so as to control the top end part curving section vertically and horizontally. A pair of brake drums confront one another, and a frictional member or brake shoe is mounted on a stationary member of the device in such a manner that it is movable with respect to the pair of brake drums. An external operating lever controls the movement of the brake shoe and the brake shoe abuts against the pair of brake drums by operation of the external operating lever so that simultaneous braking occurs.

Abstract: A suction device for an endoscope in which there is no need for the operator to close a suction pipe with his finger and in which cleaning and sterilizing are readily implemented. A suction path extends from a forceps insertion hole in a forceps receiver. A plug assembly is detachably inserted in the suction path in close contact therewith. The plug assembly includes a piston at least a portion of which is made of an elastic material and a cylinder member into which the piston is loosely fitted. The cylinder member has valve seats formed at first and second ends thereof while the piston is furnished with corresponding first and second abutting portions. An elastic extended member biases the piston outwardly. A suction hole is formed in the cylinder member through which suction pressure is communicated.

Abstract: A device for bending a medical instrument inserted into the body cavity having a flexible cylindrical coil formed by winding an elastic thin wire. The flexible cylindrical coil has a coarsely wound portion at one end portion thereof, that is designed by changing configuration or material so that one side of the coarsely wound portion is different in cross sectional area from the other side which is diametrically opposite. When a pulling string directly or indirectly fastened to the coarsely wound portion of the flexible cylindrical coil is operated, the turns of said flexible cylindrical coil are brought closer to each other on the side of the coarsely wound portion greater in torsional strength to thereby bend the one end portion of the flexible cylindrical coil towards the side of the coarsely wound portion.

Abstract: An end plug or fitting for an endoscope includes a mouthpiece member 1 having a central passage therethrough for the insertion of a medical instrument, such as a forceps, into a guide tube 5. The upper portion of the passage receives a sealing member 2 having a nozzle section 2a whose oblique end face confronts the mouth of a suction pipe 4 and whose inner diameter is smaller than that of the guide tube and approximately the same as the outer diameter of the instrument(s) to be inserted. Such a construction provides for ease of instrument insertion and withdrawal, good suction during insertion, and very low suction after withdrawal.

Abstract: A scraper brush for collecting cells from internal body passages includes a twisted wire root portion 2 mounting hairy fibers 1 between the twisted wires, and a flexible wire winding 4. A tip portion 5 of the winding 4 is stretched to present an increased pitch, and the root portion is threaded into the tip portion with the lay of the twisted wires matching the increased pitch. An additional stretched portion 5b may be provided to increase the flexibility of the brush.

Abstract: A flash device having a plurality of flashbulbs which operate sequentially by the use of time delay circuits to produce a longer duration of flashlight. Light reducing filters are used adjacent the flashbulbs to reduce the light intensity of the flashbulbs to obtain a more uniform light intensity during the length of the flash of all the flashbulbs, especially in the areas of overlapping of light intensity between adjacent sequential flashbulbs. A second embodiment modifies the light intensity by the placement of the flashbulbs in relation to the optical axis of the reflecting mirror.
