Description

(54) STETOSKOP

The invention relates to medical technology, namely to devices for auscultation.

A stethoscope is known, which has a bell-mounted sound sensor in the form of a bell with a microphone fixed in it, as well as an amplifier with a power source, telephones, and a switch 1 located in the housing.

However, the design of a well-known stethoscope does not automatically turn it on when the bell is in contact with the patient's body, which complicates the process of auscultation and limits its operational capabilities.

The purpose of the invention is to provide automatic switching on when the bell is in contact with the patient's body.

The goal is achieved by the fact that in a stethoscope containing a sound absorber mounted at the end of its body in the form of a socket with a microphone fixed in it, an amplifier with a power source, telephones and a switch in the case, the latter is made in the form of two fixed contacts fixed in the case .My moving contact, which serves as the facing

To the body and made by conductive end of the socket, the socket is mounted with the possibility of axial movement and is spring-loaded relative to the body.

FIG. 1 shows a schematic proposed stethoscope, a longitudinal section; in fig. 2 is a section A-A in FIG. one.

The device includes a housing 1, an acoustic collector mounted at its end in the form of a bell 2 with a microphone 3 fixed in it. In addition, an amplifier 4 with a power supply 5, telephones (not indicated), and a switch are placed in the housing. The switch is made in the form of two fixed contacts fixed in the housing 1 6. closed by a moving contact, which serves as an end facing the housing and made as a conductive end

7 socket 2. The spout 2 is mounted with the possibility of axial movement and interaction with the spring 8 installed in the housing.

The device is used as follows.

The telephones are connected to the device and, with the housing 1 in hand, the socket 2 is pressed against the patient's body, while the spring 8 is compressed and the conductive end 7 closes the contacts 6 of the power supply, thereby turning on the device. Controllers set the desired volume and clarity of the phones. When using the proposed device by people with reduced cases, a hearing aid can be used instead of telephones. In this way, the design of the proposed stethoscope ensures its automatic activation when the socket is contacted with the patient's body, which means auscultation and the operational capabilities of the stethoscope. la isooreteni Stetoskog, at the end of it
