Abstract

The present invention describes a method for changing frequency channels of a wireless electronic medical apparatus, which transmits or receives physiological signals produced by human bodies by means of a transmitter and its corresponding receiver of the wireless electronic medical apparatus, and such method includes a step of issuing an instruction to a channel switching module for switching a channel, if there is a conflict of using a frequency channel while several medical apparatuses are using the same frequency channel at the same time.

Claims

1. A method for changing frequency channels of wireless electronic medical apparatus, comprising the steps of:

using at least a first transceiver and a second transceiver in a wireless transmission system;

said first transceiver on a transmitter using a process of noticing said second transceiver on a wireless receiver having the same serial number to change its frequency channel, and said process comprising the steps of;

(A) detecting a signal of the same frequency channel from said first or second transceiver;

(B) transmitting a concurrent frequency hopping signal from said first or second transceiver, and noticing said second transceiver with the same serial number or said first transceiver to concurrently switch to another same backup frequency channel, so as to prevent said transceivers with different serial numbers from receiving unintended information with each other.

2. The method for changing frequency channels of wireless electronic medical apparatus of claim 1, wherein said transmitter is a chest piece of an electronic stethoscope.

3. The method for changing frequency channels of wireless electronic medical apparatus of claim 1, wherein said transmitter is a wireless electronic sphygmomanometer.

4. The method for changing frequency channels of wireless electronic medical apparatus of claim 1, wherein said receiver is an electronic earpiece.

5. The method for changing frequency channels of wireless electronic medical apparatus of claim 1, wherein said receiver is a computer.

6. The method for changing frequency channels of wireless electronic medical apparatus of claim 1, wherein said first or second transceiver is capable of receiving a press button signal from a remote control to change to another backup frequency channel for a signal transmission.
