Abstract
The utility model relates to a supersonic Doppler stethoscope, which develops an ultrasonic Doppler blood flow detection device into a style like a traditional stethoscope. The utility model is composed of ear plugs (1), sound transmission tubes (2), a circuit box (3), a plastic tube (4) and an ultrasonic Doppler probe (5), and can be used for clinic physicians in various departments as internal medicine, cardiovasology, gynecotokology and neurology, so that detection and diagnosis can be combined together, which provides convenience for patients and doctors.
Description
This utility model relates to a kind of stethoscope, is specifically related to a kind of ultrasonic doppler stethoscope.
It is unimpeded or whether block that traditional stethoscope can not be measured blood flow, can not measure fetal heart sound and Placenta Hominis blood supply situation.Even if when the auscultation heart, lower to the discrimination threshold of heart murmur, especially the diagnosis to the valve pathological changes is more difficult.The ultrasonic doppler blood flow detection method is quite ripe since the development seventies, it can measure cardiac murmur easily, the blood vessel break-make is differentiated after valve pathological changes situation, fetal heart sound, Placenta Hominis blood supply, the replantation of amputated limb, blood pressure determination to patients such as shock, child, obesities, also can be by blood vessel damage situations after the measurement trick toe blood flow research arteriosclerosis, the position of perioperatively blood vessel and understanding and considerate again condition, and sufferer such as brain blood supply situation.Above detection mode is early used clinically and is become indispensable diagnostic means, yet this equipment all is large-scale desktop apparatus so far.Patient must go to go to a doctor to special diagnosis room, can not use in department of Out-Patient Departments, brings all inconvenience.
The purpose of this utility model is this ultrasonic doppler blood flow checkout gear is developed into ultrasonic doppler stethoscope as traditional stethoscope style, use for the outpatient service doctor of each section (internal medicine, cardiology department, orthopaedics, department of obstetrics and gynecology and department of neurology), detection and diagnosis are combined, bring convenience for patient and doctor.
The purpose of this utility model is achieved in that this ultrasonic doppler stethoscope is made up of earplug, voice tube, circuit box, plastic tube, ultrasonic Doppler probe, and ultrasonic Doppler probe links to each other with voice tube by oscillating circuit, power amplifier, signal processing circuit, low-frequency amplifier circuit, the earphone in the circuit box.
Because not resembling, Ultrasound Doppler Method can not diagnose some pulmonary disease traditional stethoscope, so this utility model also the auscultation head of traditional membrane stethoscope and ultrasonic Doppler probe are attached together with relative two ends of sick body contact portion, membrane type auscultation head links to each other with voice tube by low-frequency amplifier circuit, the earphone in the circuit box.The doctor need only turn out the auscultation head as required, just can make things convenient for and promptly converts another kind of pattern to by a kind of diagnostic mode.
Because this utility model adopts battery powered,, utilize the fastening spring between the voice tube to connect a Magnet double as on and off switch for saving electricity consumption.When not using stethoscope to take off earplug, fastening spring presses down the drive on and off switch automatically and cuts off the electricity supply automatically.Need not be hand-manipulated, thus can not shorten battery life because of forgetting about powered-down.
This utility model has also designed output plughole, can an external set of headphones, monitor or recorder.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of this utility model embodiment 1;
Fig. 2 is the circuit diagram of this utility model embodiment 1;
Fig. 3 is the structural representation of this utility model embodiment 2;
Fig. 4 is the circuit diagram of this utility model embodiment 2.
Embodiment 1: this ultrasonic doppler stethoscope is made up of earplug 1, voice tube 2, circuit box 3, plastic tube 4, ultrasonic Doppler probe 5 as shown in Figure 1, and ultrasonic Doppler probe 5 links to each other with voice tube 2 by oscillating circuit, power amplifier, signal processing circuit, low-frequency amplifier circuit, earphone in the circuit box 3 as shown in Figure 2.Fastening spring between the voice tube 2 connects a Magnet double as on and off switch 7.Output plughole 8 is arranged on the circuit box 3.
Embodiment 2: this ultrasonic doppler stethoscope is made up of earplug 1, voice tube 2, circuit box 3, plastic tube 4, ultrasonic Doppler probe 5, membrane type auscultation 6 as shown in Figure 3, membrane type auscultation 6 and ultrasonic Doppler probe 5 attach together with relative two ends of sick body contact portion, ultrasonic Doppler probe 5 links to each other with voice tube 2 by oscillating circuit, power amplifier, signal processing circuit, low-frequency amplifier circuit, earphone in the circuit box 3 as shown in Figure 4; Membrane type auscultation 6 low-frequency amplifier circuit, an earphone that pass through in the circuit box 3 link to each other with voice tube 2.Fastening spring between the voice tube 2 connects a Magnet double as on and off switch 7.Output plughole 8 is arranged on the circuit box 3.
This utility model is with ultrasonic doppler blood flow checkout gear miniaturization, be designed to the stethoscope type blood flow detecting device that the doctor can carry, again with the traditional stethoscope complementary pluses and minuses that unite two into one, constitute a kind of stethoscope of more perfect functions, bring more convenient diagnostic means more efficiently for the doctor of Out-Patient Departments.The first-aid patients and the medical teaching that are particularly useful on the ambulance use.
