Various devices exist in the prior art which are directed to sundry functions such as recording muscle movements or relating to other dental dimensioning devices. Exemplary of such prior art are U. S. Pat. Nos. 3,610,227; 3,129,510; 3,075,573; 3,557,855; 3,614,950; 2,060,555; 2,758,375; 1,944,601; 3,056,210; 2,902,769; 2,552,385 and 2,299,285. None of the above prior art, however, is concerned; with detecting the existence of an improper swallow.
SUMMARY OF THE INVENTION An object of this invention is to provide a device which may be used for diagnosing an abnormal swallow.
A further object of this invention is to provide such a device which is simple in construction and use thereby lending itself to ready availability for ultimate users.
In accordance with this invention a device for diagnosing an abnormal human swallow comprises a support member for fitting over the teeth of the user with the shaft slidably mounted at one end in the support member and a contact member mounted at the other end of the shaft for being disposed in the mouth of the user and with resilient means acting between the support member and contact member to hold the contact member at a relatively fixed distance from the support member during a normal swallow and to permit the shaft to slidably project from the support member during an abnormal swallow by the force of the tongue against the contact member.
The support member may be properly positioned on the teeth by an arcuate groove on the lower surface of the support member. The contact member is advantageously disc shaped and includes a dished-out recess on its tongue contact surface with a peripheral rim or flange around the recess to assure proper positioning of the tongue against the contact member.
THE DRAWINGS FIG. 1 is an end elevation view of a diagnostic device in accordance with this invention;
FIG. 2 is a side elevation view of the device shown in FIG. 1;
FIG. 3 is a top plan view of the device shown in FIGS. l-2;
FIG. 4 is a bottom plan view of the device shown in FIGS. l-3;
FIG. 5 is a front elevation view of the device shown in FIGS. 14;
FIG. 6 is a cross-sectional view taken through FIG. 4 along the line 66;
FIG. 7 is a cross-sectional view in elevation similar to FIG. 6 in a different phase of operation; and
FIG. 8 is a front elevation view similar to FIG. 1 of a modified diagnostic device in accordance with this invention.
It is noted that FIGS. 1-5 and 8 are drawn to a scale enlarged 1% times full size, while FIGS. 6-7 are at a scale double full size.
DETAILED DESCRIPTION As illustrated in the drawings the diagnostic device 10 includes a support member 12 which is generally bowed shaped with the ends 14, 14 thereof coverging toward each other and toward contact member 16 mounted on the end of shaft 18 which in turn is slidably held in support member 12. The lower surface 21 of support member 12 includes an arcuate groove 20 shaped to generally conform to the maxillary arch of the user. In practice a few different size devices may be necessary to accommodate different age groups. As indicated in FIGS. 4 and 6 tongue contact member 16 has a dished-out recess 22 on its contact surface thereby creating a peripheral rim or flange 24 to guide the tongue T into proper position against contact member 16. Resilient means such as a spring 26 reacts between support member 12 and contact member 16 to maintain the contact member a fixed distance from the support member. The end of shaft 18 has an enlarged flattened portion 28 which acts as a stop to prevent the shaft and contact member from becoming dislodged from support member 12. Shaft 18 is slidably mounted in wear sleeve 30 as best shown in FIGS. 6-7.
In practice device 10 is inserted into the mouth of the patient with the lower teeth T being positioned in groove 20 to assure proper relative positioning of the device with respect to the tongue. The distance d between the contact member and the support member as measured, for example, from the center of contact surface 22 to the center line of groove 20 is about inches or approximately 1 1/16 inches in the illustrated embodiment so that the tongue may barely contact surface 22 during a normal swallow. After device 10 has been inserted in the mouth, the patient is instructed to place the tongue against contact surface 22 and then swallow. Resilient means or spring 26 is so selected as to maintain contact member 16 and thus also shaft 18 relatively stationary during this normal swallow. If the swallow is abnormal as indicated in FIG. 7 the force created by the tongue is such to cause the contact member 16 to shift toward support member 12 which in turn causes the end of shaft 18 to project from the support member thereby providing a clear visible indication to the orthodontist that the swallow is abnormal. Advantageously, support member 12 has an arcuate inner edge 13 to accommodate disc 16 when the disc is moved outwardly by the tongue.
If desired indicia such as colored rings or spaced lines I contact member 16A is made oval or eliptical shape to more generally conform to the general configuration of the tongue. In this embodiment suitable means are provided to prevent any rotational movement of contact member 16A and thereby assure proper orientation to the contact member with respect to the tongue. Thus in the embodiment illustrated in FIG. 8 shaft 18A is made non-circular such as of square cross-section and slides in a complimentary shaped sleeve in the support member thereby preventing any rotation of the shaft and contact member while still permitting the shaft to slide in and out.
