To all whom t may concern.'
Be it known that I, FERDINAND GRosHANs, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Dental Saliva-Ejectors, of which the following is a specification.'
This invention relates to improvements in dentalV saliva ejecto-rs and has for its object to provide an improved construction of saliva ejector that will overcome the serious objections to ejectors of this kind now in use.
Some of the objectio-ns to the saliva ejectors now in use by the dental profession are that the perforations, through which the saliva must pass, become cut off by the tissues in the month being drawn over the per-V forations; that particles of matter are drawn through the perforations into the ejector but frequently do not pass out from the latter and great difficulty is experienced in` removing such particles, and that the difficulties experienced in sterilizing the ejector-passages and chambers is so great, and the results so uncertain, that many patients and dentists refuse to use saliva ejectors.
The objects, therefore, of the present invention are to provide an improved construction and arrangement of parts of a dental ejector' which will not embed itself in the soft tissues to such extent as Vto close the perforations; whose interior passages may be'readily examined and particles of matter removed therefrom and whose parts may be separated-to expose the interior surfaces to the direct action of sterilizing agents so that a thorough Sterilization may be effected.
lith these objects in view, the invention is illustrated in the accompanying drawing, in which.'- Y Y Figure 1, shows the improved ejector in side elevation. Fig. 2, illustrates the ejector tube on an enlarged scale with the mouth bell removed therefrom,-a portion of the tube being in section to show the location of a cleaning perforation and the means for closing the same. Fig. 8, shows an enlarged sectional detail of the detached body of the mouth bell, and Fig. 4, illustrates an enlarged cross-sectional detail through the detached button head of the mouth bell.
In practice the parts of the ejector may be constructed, of metal, glass or a rubber composition, and of course it is to be used tube bend.
.having a passage 6, 4therein and also provided with a bend 7, nat one end thereof. The straight end .8, of the tube has a form that will permit'the ready connection there-l withof fa flexible rubber hose or tube k9;
The end of the bendV 7, is vprovided witn ex-j j and upon removal will permit access to the passage for the purpose of enabling the latter to be opened in case of stoppage.
.A bell-shaped or flaring body 13, is connected toand depends from the end of the This flaring bell body has an diameter at the lower end than at its upper end, and. at said smaller upper end said body is provided with interior screw threads 15, which engage the exterior threads 10,
on the bent end of the tube. At the larger lower end, .the bell body is provided with .exterior screw threads 16, and immediately the larger lower end ofthe bell body and said head has a broad outer lower face'19, and also has an upwardly curved or rounded annular guard rim 20. This head is also provided with a cavity` 21, in its upper side and the wall of this cavity, which also forms said rounded annular rim, is provided with interior screw threads 22, so as to engage the exterior threads on the larger lower end of the bell body. When the but* ton head 18, is attached to the larger end of the bell body its rounded annular rim forms an annular guard below the perforations 17, in the bell body and at the same time the head forms a broad bearing surface to seat on the soft tissues in the mouth and therefore distributes the pressure on the tissues over an extended surface. By providing the rounded annular guard rim 20, beneath the perforations 17, the soft `or screw 12, serves to clo'se the said opening soy tissues in the mouth are prevented from closing around said perforations and thereby cutting oli the suction. By forming the ejector in sections, the tube 5; flaring body 13 and socketed or recessed head 18, may all be separated and thoroughly cleaned and sterilized as the sterilizing and cleaning agents may have ready access to all interior and exterior surfaces.
I-Iaving thus described my invention what I claim is,-
l. In a saliva ejector for the mouth the 'f L, combination with a tube having a passage therethrough said tube having a bend therein of a hollow body detachably connected to the bent end of the tube said body flaring in a direction away from its attaching end and provided with circumferential perfora- .tions around itslarger end and a head detachably connected to the larger flared end of the hollow body beneath the perforations.
2. In a saliva ejector for the mouth, the
vcombination with a tube having a bend at Copies of this patent may be obtained for one end and a passage therethrough, of a hollow bell-shaped body having' its wall ilaring outwardly and at the smaller end said body having interior screw-threads to detachably connect with the bent-end of the tube and at the larger end said body having exterior screw-threads and perforations which latter are immediately above the eX- terior screw-threads, and a head having a cavity in its upper side with an upwardlycurved annular guard rim that terminates just beneath the perforations in the body said guard rim of the head being provided with interior screw-threads to detachably engage the exterior threads on the large]` end of the body.
In testimony whereof I afliX my signature in presence of two witnesses.
FERDINAND GROSIIANS.
