Drawings
The invention will be further explained with reference to the drawings and examples, wherein:
fig. 1 is a schematic structural view of a wireless stethoscope provided in an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the wireless stethoscope in this embodiment is composed of the following parts:
(1) the auscultation head: the device comprises a shell (not shown in the figure), and a sound sensor, a signal processing unit and a wireless signal transmitter which are fixedly arranged in the shell, wherein the sound sensor, the signal processing unit and the wireless signal transmitter are sequentially connected; wherein, sound sensor is used for gathering sound signal and converting it into the signal of telecommunication, has adopted 2 sound sensor in this embodiment: the stethoscope head is characterized by comprising a shell, a stethoscope head, a sensor and a control circuit, wherein the shell is arranged on the surface of the shell, which is far away from the human body and can be called an environmental sound sensor; one is installed on the casing of auscultation head and is close to the one side of human body, can be called human sound sensor for gather the stack of the biological sound of human body and the sound of the surrounding environment that the human body is located, signal processing unit is used for carrying out relevant processing to above-mentioned signal of telecommunication, including differential processor, wave filter, signal amplifier, the AD converter that connects gradually:
the difference processor is used for carrying out difference processing on the sound signals collected by the human body sound sensor and the environment sound sensor so as to obtain biological sounds (including heart sounds, intestinal sounds, lung sounds and the like) of the human body;
the filter is used for filtering the received signals, namely filtering the signals which are not in a preset frequency range, and as the frequency range of heart sounds is 0-600 Hz, the frequency range of bowel sounds is 0-1500 Hz, and the frequency range of lung sounds is 100-1500 Hz, according to the frequency range of heart-intestine lung sounds, the embodiment can adopt 3 special filters so as to be switched among different filters when needed;
the signal amplifier is used for amplifying the signals, and the signals are amplified in the embodiment because the heart, intestine and lung sounds of the human body collected by the sound sensor are weak and accurate judgment is convenient for doctors to make;
the A/D converter is used for carrying out analog-to-digital conversion on the signals, and is convenient for subsequent wireless transmission;
(2) the earphone comprises a wireless signal receiver, a D/A converter and a loudspeaker which are sequentially connected, and also comprises a memory, wherein the memory is connected with the wireless signal receiver, and the wireless signal receiver is simultaneously in wireless connection with the wireless signal transmitter of the auscultation head; wherein,
the wireless signal receiver is used for receiving the digital signal sent by the wireless signal transmitter of the auscultation head;
the memory is used for storing the data received by the wireless signal receiver for later reference and teaching;
the D/A converter and the loudspeaker are used for converting the received digital signals into analog signals and then playing the analog signals, and doctors can diagnose according to the sound.
In the wireless stethoscope, the wireless signal transmitter can set its own address (i.e. the address of each stethoscope head is different), so that the communication address of the wireless signal receiver can be set as the address of the stethoscope head to be listened to at the earphone end during application; in addition, the auscultation head is in a dormant state at ordinary times, when auscultation is needed, the earphone pages the auscultation head corresponding to the communication address through the wireless signal receiver, and the auscultation head enters an activated state after receiving the paging message to start working and carries out real-time data transmission with the earphone. In this embodiment, the wireless stethoscope can have two working modes: one is a single person auscultation mode, and the other is a multi-person combined auscultation mode. In a single auscultation mode of one person, only one earphone is needed, and wireless connection is established between the earphone and the auscultation head to realize auscultation; under many people's joint auscultation mode, need to use a plurality of earphones to all set for the address of same auscultation head with the communication address of the wireless signal receiver of these earphones, can realize a plurality of earphones and carry out real time data transmission with same auscultation head simultaneously after the activation like this, thereby realize a plurality of doctors and jointly auscultate.
The above embodiments are merely for illustrating the technical solutions of the present invention and are not to be construed as limiting, and the present invention is described in detail with reference to the preferred embodiments. It should be understood by those skilled in the art that various modifications and equivalent substitutions may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and all the modifications and equivalents should be covered by the scope of the claims of the present invention.
