Combo suction regulator for medical use
First Claim
1. A combo suction regulator for medical use which comprises a cover (casing), a vacuum gauge, a regulating module, a integrated flow channel module, an intermittent timer module, a mode select switch, a vacuum relief and an air buffer, wherein:
- A. the air buffer is disposed inside the casing and integrally formed as a whole with the integrated flow channel module, there are two holes disposed at a bottom of the air buffer thereof for communicating corresponding the holes of flow channels that are susceptible to interference in the integrated flow channel module;
B. a flow channel board and a bottom board coupled with each other to form the integrated flow channel module;
the bottom board has a probe/adapter port at a middle part thereof which connects with an input vacuum source via a threaded connecting inlet, and three needle valves on a board surface thereof for communicating with corresponding flow channels and adjusting the time on and off;
the flow channel board has a pole at an upper end of a front side thereof for installing the mode select switch, and four to six connection holes for communicating with flow channels on the flow channel board;
in a middle part of the front side of the flow channel board, a metal pole, a channel hole and a valve seat of a change valve are disposed which are all connected to a intermittent timer;
in a lower part of the front side of the flow channel board, an sleeve seat for installing the regulating module is disposed, which have mouths communicating with flow channel; and
a fitting port at a bottom side thereof with a threaded is outlet of the suction regulator output;
C. the intermittent timer module comprises the diaphragm piston disposed on one side and the change valve disposed on another side of the middle part of the front side of the flow channel board;
the diaphragm piston comprises mainly a body, a diaphragm, a return spring and piston rod;
the change valve comprises mainly a connecting rod, a crank and a torsion spring, a valve plate and a valve seat;
the diaphragm piston connects to and controls the change valve through the piston rod.

Abstract
A combo suction regulator for medical use which comprises a cover (casing), a vacuum gauge, a regulating module, a integrated flow channel module, an intermittent timer regulating means, a mode select switch, a vacuum relief and air buffer, wherein a flow channel board and a bottom board coupled with each other to form the integrated flow channel module; the air buffer are disposed inside the casing on the board surface of the flow channel board which forms part of the integrated flow channel module, and tow holes disposed at a bottom part thereof for communicating corresponding flow channels of the integrated flow channel module; a sleeve seat is disposed at the center for installing vacuum gauge. The probe/adapter port is used to input of vacuum source and needle vales are used to timer adjusting in the bottom board at a middle part thereof; the flow channel board has a pole on a front side thereof for installing the mode select switch, and channel holes for communicating with flow channels on the flow channel board thereof; in a lower part of the flow channel board, an sleeve seat is disposed for installing the regulating module, which communicates with a flow channel on the flow channel board and adjusts the output vacuum; the fitting port is used to output of the suction regulator and disposed the bottom side. The intermittent timer module comprises the diaphragm piston disposed on one side and the change valve disposed on another side of the middle part of the front side of the flow channel board.
