Embodiment Construction

[0054] In order to explain the overall concept of the present application more clearly, the following detailed description will be given by way of examples in combination with the accompanying drawings.

[0055] The embodiment of this application discloses a circuit of medical communication equipment, such as figure 1 As shown, it includes a signal gating circuit 101 , a codec circuit 102 , an echo cancellation circuit 103 and a power amplifier circuit 104 .

[0056] The following is an example of a call between A and B to illustrate the process of echo generation during a call and the principle of echo cancellation. Wherein, the communication device used by A is defined as device A, and the communication device used by B is defined as device B. After A sends an audio signal to B, the audio signal sent by A is played by the speaker of device B. At this time, the microphone on device B will obtain the audio signal being played, and at the same time obtain the audio signal sent...

Abstract

The invention discloses a circuit of medical communication equipment. The circuit comprises a signal gating circuit, a coding-and-decoding circuit and an echo eliminating circuit. The signal gating circuit is connected with the decoding output end of the coding-and-decoding circuit and the input end of the echo eliminating circuit. The input end of the echo eliminating circuit is connected with the decoding output end of the coding-and-decoding circuit. The output end of the echo eliminating circuit is connected with the coding input end of the coding-and-decoding circuit. The signal gating circuit is used for determining for gating the audio signal transmission line of a local microphone or the audio signal transmission line of a handle microphone according to a received gating control signal. The signal gating line transmits the audio signal which is acquired by the local microphone or the handle microphone to the echo eliminating circuit through the audio signal transmission line ofthe local microphone or the handle microphone, and transmits the audio signal which is transmitted by the decoding output end to power amplifier equipment which corresponds with the local microphoneor the handle microphone. The circuit of the medical communication equipment, and the medical communication equipment have advantages of realizing communication line switching of the medical communication equipment, improving communication quality and transmitting the audio signal through using the network as a medium.

Description

technical field [0001] The present application relates to the technical field of medical communication, in particular to a circuit of a medical communication device and the medical communication device. Background technique [0002] Currently, many hospitals are equipped with medical communication equipment. Medical communication equipment includes medical communication equipment for medical staff and patient communication equipment for patients. [0003] Whether it is medical communication equipment or patient communication equipment, most of the existing medical communication equipment are analog communication equipment. However, due to its own characteristics, analog communication equipment usually has weaknesses such as high equipment noise and difficulty in networking. In order to solve this problem, some enterprises began to design and produce digital medical communication equipment. However, due to the special functions of the existing digital medical communication...
