  • Patent number: 4085755
    Abstract: The specification describes a fluid drainage bag having first and second plies, a fold in the first ply, and a drainage opening closed by a flap valve in the fold. The fold is held open by means of a flexible drainage tube maintained in a flexed position between the fold and the upper end of the bag. The opening of the fold draws the flap valve away from the second ply so that it does not stick in the open position to the second ply.

  • Patent number: 4078555
    Abstract: An endoscope having control mechanism for permitting fine adjustment of the bending operation of a flexible tip. The flexible tip of an endoscope is controlled in its bending direction by rotating a knob at the opposite end of the endoscope. The knob is engageable by a braking clutch mechanism for stopping the rotation thereof and thereby fixing the position of the endoscope tip. A separate release mechanism is provided for temporarily disengaging the knob from the braking force of the clutch mechanism without requiring the release of the clutching mechanism to its disengaged state. The temporary release mechanism is operated by means of a button located on the knob thereby permitting easy operation while the physician or other operator is performing a viewing operation or the like.

  • Patent number: 4073294
    Abstract: A negative pressure drainage vessel equipped with an interior resilient flexible diaphragm and means for producing a negative pressure on that side of such diaphragm which is proximate a fluid recovery area. The opposite side of the diaphragm is exposed to atmospheric pressure. A progressive rise of fluid level in the container, as may tend to increase the pressure on the negative-pressure side of the diaphragm, is accompanied by an elastomeric contraction "pull-down" or "pull-up" of the diaphragm so as to maintain essentially the negative pressure required for an essentially constant suction condition for a large progressive rise in fluid level. The negative pressure may be increased by periodic application of vacuum as may be effected by an air-evacuation mechanism. A separate, liquid-filled bag may be employed together with an appropriate valving means.

  • Patent number: 4072147
    Abstract: A radiation endoscope is described wherein a laser or other radiation source is employed for therapeutic purposes. Radiation energy may be accurately directed at a target in a body cavity with the use of a marking spot whose light energy is passed along an optical path in the sheath of the radiation endoscope to the cavity area on which the radiation beam is incident. Eye protection for an operator of the radiation endoscope is obtained with the use of a variable filter interposed in an image path and coupled to correspondingly reduce the beam radiation effective in the body cavity as the image path transmissivity is enhanced. In one embodiment, attenuation of beam radiation is obtained by using a variable density optical filter coupled to the filter operative in the image path. In another embodiment, radiation beam attenuation is achieved by deriving a radiation beam control signal from the filter operative in the image path.

  • Patent number: 4066070
    Abstract: Main and auxiliary cuffs made of an elastic material such as rubber, etc., are mounted in close proximity to each other on the forward end portion of a flexible sheath of a tubular medical instrument. The flexible sheath is inserted into a body cavity of a human being and with further insertion of the flexible tube the main cuff is contacted, while at the expanded state, with the wall surface of the body cavity and when the flexible sheath is forwardly pushed the portion of the main cuff is rearwardly deformed, while effecting a rolling contact with the wall surface of the body cavity, to permit it to ride on the auxiliary cuff. When the auxiliary cuff is then expanded to cause the corresponding wall surface of the body cavity to be expanded, the main cuff is separated away from the wall surface of the body cavity to cause the portion of the main cuff to be forwardly pushed ahead into an original position.
