Title:
SUCTION OPERATING PART STRUCTURE OF ENDOSCOPE
Document Type and Number:
Japanese Patent JP3217996
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the number of parts, to make assembling, disassembling, and cleaning easier, and to stabilize switching operation for a long period, by equipping a button to execute open/close of an upper opening, communicating/closing of an air suction hole, communicating and closing between upper/lower halves, and closing/opening of a lid of a lower part protruding part utilizing elastic deformation of a casing tubular body.
SOLUTION: For instance, when body fluid, etc., is discharged outside, an operation button 28 is pressed to elastically downward deform the upper half part 11 of a tubular body 21 to convert an air suction hole 27 and a communicating hole 20 from a non-suction condition, in which both are communicated with each other to a suction condition. That is, the communication between upper and lower halves 11, 10 is closed and a port 8 and a suction channel are communicated. Consequently air is flown from a small diameter part 15 to the port part 8 and sucked by the suction channel to discharge body fluid, etc. When the pressing is released, each part will be restored by elastic force of the upper half part 11 to be in a non-suction condition. Thus the switching operation can be easily done and assembling/disassembling is made easier.
