ABSTRACT:
A suction device is disclosed comprising a molded plastic handle having a suction bore therethrough and a spigot for connection to the hospital suction source. The device further comprises a probe having a suction passage therethrough and terminating in a suction tip. At its proximal end the probe is formed with a male thread which threadedly engages in internal threads provided at an enlarged entrance portion of the handle. The proximal end of the probe terminates in an end member which fits within a reception bore located between the front bore and the suction bore of the handle. The dimensions of the end member are such that there is an annular space between the reception bore and the end member and this space connects through an opening through the suction bore. The handle has a controllable suction port whereby the suction at the tip can be controlled. This port opens into the annular space downstream of the connection between the opening and the suction bore.
Various modifications including modifications for use with flexible catheters are also described.
