Description

 The invention relates to medical equipment and can be used in diagnostic studies and to improve the quality of the educational process in the development of auscultation techniques.

 A device for auscultation is known, comprising a sound pickup head with two cameras, a sound duct and a headband, one of the cameras being made with corrugated side walls (SU, ed. St. N 226084, class A 61 B 7/00, 1964).

 This design of the device for auscultation, although it provides increased sensitivity to the low-frequency components of auscultatory signs, makes it difficult to obtain reliable information, since when using one stethophonendoscope, the disruption of the auscultation process is observed.

 During a pause, the characteristics of the sounds being heard can dramatically change and migrate. The teacher comments, only assuming that the student hears the same as he heard. At the same time, even a slight displacement of the bell of the trainee’s phonendoscope from the zone that the teacher had previously been asculted can lead to a change in the characteristics of the sounds being studied.

 In addition, the teacher and student often use stethophonendoscopes of various modifications, which also changes the characteristics of the sounds studied during auscultation for the purpose of training.

 A stethophonendoscope is also known, including a head with a sound receiver (bell), a forked prefix, a sound pipe system, a tee, headband springs, ear tubes with ear olives and a switching tool [1].

 This embodiment of the listening device (stethophonendoscope) allows researchers or the teacher and the trainee to listen to the same thing, since they use the common head of the stethophonendoscope and different sound ducts, auditory tubes with ear olives, but it does not allow dialogue between them, so necessary to focus on specially listening sounds.

 The objective of the invention is to avoid these difficulties and to create such a stethophonendoscope, which, with the relative simplicity of the design, provided the opportunity for several researchers or a teacher and trainees to use, as well as allowing dialogue between them without interruption in auscultation.

 This is achieved due to the fact that the training stethophonendoscope, including a head with a sound receiver (bell), a fork attachment, a sound guide system, a tee, headband springs and ear tubes with ear olives, is equipped with at least one intercom sound receiver connected to the sound pipe system and means for its overlap .

 It is also possible to perform a stethophonendoscope when the interphone is installed on a tee or on a fork prefix, or on each sound pipe.

 In FIG. 1 shows a General view of a training stethophonendoscope; in FIG. 2 is a diagram of a paired training stethophonendoscope with an interphone on a forked console; in FIG. 3 - the same on each sound pipe; in FIG. 4 is a diagram of a work using the group option and the location of the interphone receiver either on the first fork-top box or on the tees; in FIG. 5 is a diagram of a training stethophonendoscope in an audience using an electronic intercom receiver.

 The training stethophonendoscope contains a head 1 (Fig. 1) with sockets 2, 3 and 4 and a forked prefix 5 connected by sound ducts 6 and 7 with tees 8 and 9 and branching sound ducts 10, 11 and 12, 13, connected with auditory tubes 14, 15 and 16, 17, interconnected by springs 18 and 19 with central hinges 20, 21. Hearing tubes end with ear olives 22, 23 and 24, 25. On tees 8 and 9, earphones 26, 27 are connected, connected with sound duct systems 6 and 7 and having means for turning them off 28 and 29. The interphone 26 can be turned on chen a forked attachment 5 (FIG. 2) and also have means for disabling 28. The negotiation horn 26 with forked attachment 5 can be connected, for example, a tubular twin-turbo 30 for convenience as the teacher and the student.

 In FIG. 4 shows a diagram of the use of a group of trainees by this educational stethophonendoscope. To do this, the forked prefix 5 is increased, for example, by two or three of the same forked prefixes 31 and 32, 33, and so on, until it is possible to include all students in the educational process.

 Interphone receivers 26, 27 can be installed both on the first fork-top box 5 and on each tee, as shown in FIG. 13.

 In an audience equipped with means for connecting sound ducts 6 and 7 (Fig. 5), a teacher using an electronic conversation sound receiver, while listening to the person being studied, comments on the sounds heard to emphasize the attention of the trainees.

 A training stethophonendoscope is used as follows.

 In the first (simplified) version, when using an educational stethophonendoscope, a teacher and a student (Figs. 1, 2 and 3) insert olives 22, 23 and 24, 25 into the ears, and head 1, for example, a bell 2, is brought to the body of the subject and pressed for of obtaining a sealed system: the person under study - an educational stethophonendoscope - teacher, student.

 At the same time, sounds from the person under study through the bell 2 (or 3, 4) of the head 1 (Fig. 1) forked prefix 5, sound ducts 6 and 7, tees 8 and 9, branching sound guides 10-13, auditory tubes 14-17, ear olives 22-25 are perceived by the teacher and student. Using the shutdown means 28 and 29, they include intercoms 26 and 27, which allows the teacher and student to exchange opinions about what they heard while talking, without removing the headband from the ear canals, through the intercom. At the same time, sound waves propagate through the sound pipe system of the connected stethophonendoscopes.

 You can perform a training stethophonendoscope with one interphone sound pickup per teacher and student (Fig. 2). The interphone 26 with means for its inclusion, shutdown 28 through a pipe 30 is connected to a forked prefix 5.

 Using several additional fork prefixes 31, 32, 33 (Fig. 4), it is possible to provide additional training for 4 more students.

 Interphone 26, 27 can be made with their own sound bridges connected to the head 1 (Fig. 3), for example with a forked prefix 5.

 When performing a training phonendoscope with electronic intercoms (microphones) and telephones installed in the bell 26 or 3, 4 heads 1 and ear olives 22-25, it can be used in classrooms to teach a large number of students.

 Using the proposed design of the educational stethophonendoscope allows you to reduce the preparation time of the student, improve the quality of training and reduce labor costs in the educational process, and can also be used when conducting joint examination of patients with two or more specialists.
