Description
Technical field
This utility model relates to a kind of integral type doppler baby ' s heart instrument carrying out expanded application, for monitoring Fetal Heart Rate, belongs to technical field of medical instruments.
Background technology
Fetus-voice meter is a kind of Medical Instruments, is used for detecting fetal heartbeat, tire tone signal faint for fetus is amplified, people can be easy to hear, according to specialist medical knowledge, can judge that whether fetus is normal by Fetal Heart Rate or instantaneous heart rate curve.
Technologically speaking, doppler baby ' s heart instrument is divided into integral type and split type two kinds, and fetal heart sound signal faint for fetus amplifies by integral type fetus-voice meter, and split type fetus-voice meter comprises probe module, date processing/display module.
Domestic fetus-voice meter popular mostly in the market is integral structure, easy to use, but only can realize the function listening to fetal heart sound.The fetus-voice meter of split-type structural, its date processing/display module is all furnished with special processor and memorizer.
Due to the difference of processing mode, user can only select the one in integral type fetus-voice meter and split type fetus-voice meter usually.
Utility model content
The purpose of this utility model, is to provide a kind of integral type doppler baby ' s heart instrument that can be realized expanded application by audio interface, in expanded application, adopts data processing technique and provides display module.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of integral type doppler baby ' s heart instrument carrying out expanded application, comprise earphone interface module and the ultrasonic transducer be connected successively, sound amplifying signal circuit, height channel filtering circuit, analog switch and audio amplification block, one end of earphone interface module is connected with analog switch, and the other end connects outside expanded application terminal; The fetal heart sound signal that ultrasonic transducer gathers is successively through sound amplifying signal circuit, height channel filtering circuit, analog switch and audio amplification block, and audio amplification block plays fetal heart sound signal; Earphone interface module detects the signal of expanded application terminal and control simulation change-over switch, and the acoustical signal after amplifying is sent to expanded application terminal, and expanded application terminal processes voice data.
Further, also comprise display lamp, described display lamp is connected with analog switch.
Further, described display lamp is LED.
Further, described earphone interface module employing diameter is the audio interface of 3.5 millimeters.
Further, described sound amplifying signal circuit adopts speaker.
After adopting such scheme, the integral type doppler baby ' s heart instrument carrying out expanded application of the present utility model can in conjunction with the function of traditional integral type fetus-voice meter and split type fetus-voice meter, tire sound can not only be detected, but also expanded application terminal can be connected the related data collected is arranged and analyzed, easy to use, cost is low.
Accompanying drawing explanation
Fig. 1 is integrated stand composition of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 1, a kind of integral type doppler baby ' s heart instrument carrying out expanded application comprises earphone interface module and the ultrasonic transducer be connected successively, sound amplifying signal circuit, height channel filtering circuit, analog switch and audio amplification block, one end of earphone interface module is connected with analog switch, and the other end connects outside expanded application terminal.
Ultrasonic transducer gathers fetal heart sound signal successively through sound amplifying signal circuit, height channel filtering circuit, analog switch and audio amplification block, and audio amplification block plays fetal heart sound signal; Earphone interface module detects the signal of expanded application terminal and control simulation change-over switch, and the acoustical signal after amplifying is sent to expanded application terminal, and expanded application terminal processes voice data.
Sound amplifying signal circuit adopts speaker, and user can listen to fetal heart sound with earphone, also can listening to fetal heart sound by putting outward, at the acoustical signal that expanded application terminal processes is crossed, also can pass back to ultrasonic probe and playing.The acoustical signal of expanded application terminal, passes back to described fetus-voice meter and pacifies and education function to realize fetus, can realize Fetal Heart Rate warning function simultaneously.
Described earphone interface module employing diameter is the audio interface of 3.5 millimeters.
Described fetus-voice meter also comprises display lamp, and described display lamp is connected with analog switch.Described display lamp is LED.When described fetus-voice meter is when working, it is luminous that analog switch controls display lamp.
Embodiment 1: conceived 20 weeks of certain anemia of pregnant woman, ultrasonic transducer collects fetal heart sound signal, heart beat rhythm is 148 beats/min, earphone interface module detects that integral type doppler baby ' s heart instrument has been connected to expanded application terminal, fetal heart sound signal is transferred to expanded application terminal by tone frequency channel wire by earphone interface module, expanded application terminal one example is APP, fetal heart sound signal processes by APP, be converted to digital signal display, fetal heart sound signal is transferred to sound amplifying signal circuit to amplify simultaneously, user can observe fetal rhythm data by APP, fetal heart sound can be heard simultaneously.
Embodiment 2: conceived 20 weeks of certain anemia of pregnant woman, ultrasonic transducer collects fetal heart sound signal, the instantaneous Fetal Heart Rate detected has for several times more than 160 beats/min (normal tire heart rate range is 120 beats/min-160 beats/min), when Fetal Heart Rate finds when expanded application terminal processes to have exceeded normal range, alarm signal will be added in fetal heart sound signal, input described fetus-voice meter, speaker plays fetal heart sound signal and alerting signal simultaneously, and prompting anemia of pregnant woman notes.
Embodiment 3: certain anemia of pregnant woman the pregnancy period by fetus-voice meter equipment collect fetus in abdomen time sound, as the heartbeat of anemia of pregnant woman oneself, expanded application terminal is stored into after output, after baby due in one month, fetus-voice meter described in the Speech input of storage can be play, for newborn baby manufactures familiar environment, realize pacifying function.
The integral type doppler baby ' s heart instrument carrying out expanded application of the present utility model can in conjunction with the function of traditional integral type fetus-voice meter and split type fetus-voice meter, fetal heart sound can not only be detected, but also expanded application terminal can be connected the related data collected is arranged and analyzed, easy to use, cost is low.
Audio interface is used to obtain fetal heart sound information, have the following advantages: the electric interfaces standard of most of intelligent terminal's audio interface is unified, interchangeability, versatility are good, this utility model is made to be easy to universal, the electric property of audio interface is stablized, and capacity of resisting disturbance is strong, and joint geometry is axial symmetry, anti-inserted without the need to worrying, connect good mechanical property; Audio interface not only can transmit audio signal, can also bidirectional transmission of digital signal.
