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.

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.

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.
