Description

Dental appliance for sound analgesia.

The utility model relates to medicine and, in particular, to devices for pain relief and dental treatment.

There is a known method of pain relief during medical interventions, for example, during dental treatment, exposure through the stereo phones to the patient’s auditory system with white noise, during which the noise intensity from each of the phones is not periodically changed in phase 1. At the same time, an electronic generator with a filter is used as a source of signals, letting in the most efficient but frequency characteristics signal with a ptum level below the pain threshold of sensitivity, i.e., safe for the patient’s hearing. However, such use of the headset robs the patient of communication with the doctor.

The device closest in technical essence is a device containing a sound analyzer, including magnetic heads for reproducing music signals from magnetic tapes and white noise, pre-amplification blocks of low-frequency (LF) signals of music and white noise channels, a signal mixer block of both channels, terminal blocks bass amplifiers and headphones 2.

A disadvantage of the known device is that

that after putting on the headphones, the patient remains deaf not only to the surrounding sounds, but, more importantly, to the voice of his doctor, i.e., the doctor’s communication with the patient during treatment or prosthetics is completely absent. To talk with a doctor

the patient needs to remove the head phones; therefore, the pain sensations sharply increase.

The problem the utility model is aimed at and the technical result of its use are associated with the need to create a device for sound analgesia, which allows maintaining constant or easily restored contact between the doctor and the patient at the right time. At the same time, to restore contact, the patient should not remove the head phones, and the doctor should not be distracted and stop working.

The technical result is achieved by the fact that in the device containing a sound analyzer, including magnetic heads for reproducing music and white noise signals, pre-amplification blocks for low-frequency signals of music and noise, a block of signal mixer for both channels, blocks for low-frequency amplifiers and headphones, are additionally introduced a transceiver in which the receiver is electrically connected to the mixer of the sound analyzer, and the transmitter is connected to the IF amplifier. and a head radiotelephone, made in the form of a headset, in the kit of which a transceiver is mounted with a telephone and a microphone via a radio channel connected to the transceiver. In this case, the receiver of the transceiver device contains a filter and an amplifier equipped with a key cascade configured to enable transmission from tonal frequency signals or a push button switch.

which includes magnetic heads 1 for reproducing music signals from magnetic tapes, white noise generator 2, blocks 3 pre-amplification of low-frequency signals of music and white noise channels, block 4 of the signal mixer of both channels, blocks 5 of the terminal amplifiers of low-frequency signals, as well as headphones 6 for the patient. A transceiver is connected to the sound analyzer; its device 7, the receiver 8 of which is electrically connected to the mixer unit 4, and the transmitter 9 - to the unit 5 of the low-frequency signal amplifiers. Transceiver; its device 7 is connected via radio channel to a head radiotelephone mounted on a headset 10 intended for a doctor when working with a patient. The headset 10 includes a transceiver 11, with a telephone 12 in one ear and a microphone 13. The receiver 8 of the transceiver 7, in addition to the receiver circuit 14 itself, includes a filter 15 and an amplifier 16 with a key stage.

A dental device operates as follows. Before starting treatment or prosthetics, the patient is put on the headphone 6, includes a music program and a white noise generator 2. The signals taken by the magnetic heads 1 are fed to the bass pre-amplification units 3, in which not only amplification, but also adjustment of sound reproduction quality occurs. In the mixer 4, the music and noise signals are mixed in the required proportions and, after amplification in the blocks 5 of the terminal bass amplifiers, are fed to the head phones 6 of the patient. If necessary, the patient can separately adjust the level of music and noise, achieving the optimal ratio. At the same time, the doctor also puts a headset 10 on the head with the patient, while he has only one telephone 12 closed, which gives him the ability to control the signals sent to the head399 c {S

nye phones 6 patients. His second ear is open and he hears external sounds, as well as, if necessary, the voice of the patient. In order to ask or answer a patient’s question, the doctor speaks into the microphone 13 of the headset 10. The doctor’s voice through the transceiver 11 in the form of a signal is transmitted to the receiver 8 of the transceiver 7, to the mixer unit 4, where it is mixed with music and noise signals and fed to Headphones 6 patients. If the microphone 13 of the doctor is constantly open (on), then through it, in addition to the doctor’s voice, the patient will receive external, extraneous sounds, violating the method of sound analgesia. Mute the microphone 13 doctor can be done using a conventional push button switch installed on the headset 10. But in this case, the doctor will be forced to be distracted by turning on and off his microphone, especially since the doctor is constantly busy with both hands. This issue in the receiver 8 is solved by the filter 15 and the amplifier 16 with a key stage, which forcibly include the transmission of tone frequency signals from the microphone 13 of the doctor to the head phones 6 of the patient. As soon as the doctor stops talking, the microphone 13 is automatically turned off, because the filter 15 does not pass on extraneous sounds to the amplifier 16. Thus, using the method of sound analgesia, the patient constantly has two-way communication with the doctor, which helps to improve his well-being and increase comfort during treatment or prosthetics.
