Claims
- 1. A method of manufacturing a ventilating/aspirating assembly comprising the steps of:
- assembling a manual aspirating control valve by placing a plunger in a closed end of an exteriorally tapered elastic seal member and placing the plunger/sealing member assembly within a tapered sealing bore of a valve body having an open top and an open bottom, folding a wall which comprises an open end of the sealing member upon itself in reverse curve orientation, anchoring and sealing said wall in said reverse curve orientation in stretch fit relation thereby biasing the sealing member into a closed sealing position by forces comprising the memory of the material from which the sealing member is made;
- placing a bottom closure and a top actuator upon the valve body following installation of the plunger/sealing member assembly;
- linearly force-fit connecting the distal and proximal ends of a sterility preserving flexible manually collapsible envelope respectively between a ventilating/aspirating fitting and the manual aspirating control valve;
- stationarily connecting the proximal end of an aspirating catheter tube to the aspirating control valve and slidably associating the distal end of the catheter tube with the ventilating/aspirating fitting.
