Abstract

PROBLEM TO BE SOLVED: To provide a jaw joint stethoscope for a medical examination, in which a pair of right and left sound reception devices are attached to a spring type grasper so as to face each other in order to attain one-operation mounting and the rapid and simultaneous auscultation of jaw joint sound on both sides in a school dental examination, etc.SOLUTION: A pair of right and left sound reception devices of a stethoscope are attached to a spring type nip grasper so as to face each other. Each of attachment parts of the sound received devices has an elastic tube structure whose angle is automatically adjusted and that has a function of fitting to a face surface and a function of transmitting reception sound. The elastic tubes are connected to L shape hard hollow pipes and the L shape hard hollow pipes are connected to tubes of auscultation sound transmission parts. The L shape hard hollow pipes and partial portions of the tubes of the auscultation sound transmission parts having a function of received sound transmission penetrate the hard hollow pipes of the spring type grasper. Spring type graspers are also attached to auditory tube parts to be mounted on an examiner. Both parts are mounted by one hand with one operation, so that jaw joint sound on both sides is simultaneously auscultated in as short a period of time as possible.

Description

  This invention adds a sound receiving device for a stethoscope, attaches it to a spring-type gripper so as to be paired with left and right, attaches it to the left and right temporomandibular joints on both sides of the face, and opens and closes the mouth The temporomandibular joint sound can be auscultated at the same time.

  Since the existing stethoscope has only one sound receiving device that listens to the body sound of the human body, it cannot simultaneously hear the body sound of a distant place such as a pair of left and right temporomandibular joints. Also, it took time to auscultate the left and right separately. It took a little time for the examiner to wear the stethoscope after each dental examination in turn at the school dental examination.

  Since 1995, screening of the temporomandibular joint has been introduced in school dental examinations. However, since about 250 people are examined per day, it is difficult to examine the temporomandibular joint in detail after the dental examination due to the time constraints imposed on each subject. The present invention has been devised so that it can be worn in as short a time as possible under the time constraints and the temporomandibular joint can be examined in more detail.

  The present invention provides a spring-type gripper with a pair of sound receiving tools using a hollow rigid pipe so that the sound generated by the left and right temporomandibular joints can be auscultated simultaneously while applying equal pressure across the left and right temporomandibular joints on both sides of the face. Attach to fit. The attachment part of the sound receiving tool has an elastic tube structure in which the angle is automatically adjusted to fit the face part and to transmit the sound reception. The elastic tube is connected to the L-shaped hard hollow tube, and the L-shaped hard hollow tube is connected to the tube of the auscultatory sound transmission unit. The L-shaped hard hollow tube that plays the role of sound reception transmission and a part of the tube of the auscultation sound transmission part penetrate through the hard hollow pipe of the spring type grasper. In addition, a spring-type gripper is also attached to the ear canal part to be attached to the examiner himself to shorten the equipment wearing time.

  After a dental examination in a group dental examination, the temporomandibular joint when the examiner wears the ear canal with the examiner himself with one hand and the auscultatory sound detector with the other hand simultaneously with one touch and opens and closes the mouth Can now be auscultated at the same time in a relatively short time. In addition, it became possible to detect early abnormalities of the temporomandibular joint that had been overlooked by conducting detailed examinations with a stethoscope.

  It is a front view of the present invention.   It is sectional drawing of this invention.

  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 4) is attached so as to be mated with the spring type gripper (5). The attachment part of the sound receiving tool is an elastic tube (2) whose role is to adjust the angle automatically and to fit the face part and to transmit sound reception. The elastic tube (2) is connected to the L-shaped hard hollow tube (3), and the L-shaped hard hollow tube (3) is connected to the tube (6) of the auscultatory sound transmission unit. A part of the L-shaped rigid hollow tube (3) that plays the role of receiving sound and the tube (6) of the auscultatory sound transmitting part are in the rigid hollow pipe (4) that is the gripping part of the spring-type gripper. It penetrates. In addition, the examiner himself / herself wears the spring-type grasper (7) with the ear canal part with one touch to shorten the instrument wearing time.

Claims (4)

  A temporomandibular joint stethoscope that can be attached to the spring-type gripper with a pair of left and right receiving devices, which are the auscultation sound detection part of a stethoscope, and can be quickly attached to both temporomandibular joint sounds by one touch.   The attachment portion of the sound receiving tool has an elastic tube structure that automatically adjusts the angle and fits the face portion and transmits the sound reception.   The elastic tube is connected to the L-shaped hard hollow tube, and the L-shaped hard hollow tube is connected to the tube of the auscultatory sound transmission unit. A part of the tube of the L-shaped hard hollow tube and the auscultatory sound transmission unit that plays a role of sound reception transmission penetrates the hard hollow pipe of the spring-type gripper.   A spring-type gripper is also attached to the ear canal part to be attached to the examiner so that it can be attached with one hand with one touch.
