Abstract

1,220,255. Suction unit for dentistry. CHIRANA ZAVODY ZDRAVOTNICKE TECHNIKY OBOROVY PODNIK ZAVOD STRASNICE. 2 May, 1968 [7 June, 1967], No. 20788/68. Heading BIT. [Also in Divisions A5 and A6] A suction unit for removing cooling liquid, solids and saliva from a patient's mouth during dental operations comprises a pump 11 which draws air from a pipe 1, leading to the patient's mouth, through a solids and liquid trap formed in the lower part of the casing by baffles 4, 8, 23, 24. Solids collect in annular well 7 and liquid passes through holes 5, 14 and collects in removable receptacle 6, whose lower end comprises a membrane valve 15, 16, through which liquid drains when pump 11 is switched off and the weight of liquid deforms valve membrane 15. If the liquid level in receptacle 6 rises sufficiently, disc 20, supported on float 18, closes the inlet to the pump at 10. The air outlet side of the pump incorporates sound absorber 12. When receptacle 6 has been removed, baffle 4 can be removed to empty well 7.
