Problems solved by technology

[0002] The heart sound detection head used in the hospital still adopts the traditional, ancient, backward, and uncivilized operation method, that is, to use multiple sticking plasters and adhesive tapes to fix the detection head closely to the detection surface of the person being examined, which is time-consuming. , laborious, unhygienic, causing pollution and pain, low work efficiency
Moreover, because the wire has no fixed device for positioning, it is easy to be bent and twisted, and because the wire is very long, the wire will swing and deform when people move a little or vibrate caused by external factors, causing telecommunications interference, thereby affecting the accuracy of detection

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0010] The protective cover (3) has a stepped through hole in the middle, one end is conical, one end is cylindrical, and one end has an internal screw hole.

[0011] The upper part of the outer casing (5) has an external thread at one end and an internal screw hole at the other end. There is a horizontal and straight through hole in the middle. The lateral end face is a tapered hole. The lower part is conical and cylindrical. The spout (9) of the hole has anti-slip, anti-off serrations on its periphery.

[0012] The upper end of bell jar (8) has external thread, and the lower end is the spherical cavity that communicates with upper cavity.

[0013] First the threaded end of the bell jar (8) coated with glue is screwed into the inner screw hole on the top of the outer casing (5) and connected as a whole, then the acoustic sensor ( 6), put it into the ...

Abstract

The detector head of heart sounds is an important device matched with medical instruments, for example, coronary heart disease non-traumatic detection instrument related to detection of human heart sounds and blood vessel sounds. It is characterized by that the sound can be passed through the sound sensor, and converted into electric orginal and transferred into the related instrument by means ofconductor. Said detector head of heart sound is formed from sound sensor connected with conductor and support device on which the sound sensor is placed. Said support device is an external cover shell which possesses an inverted mouth and is connected on the bell-jar connected with sound sensor, and a rubber suction cup is connected on the invented mouth. Said detector head can raise sensitivity and accuracy of detection.

Description

technical field [0001] The invention relates to an important device used in conjunction with medical equipment, especially in conjunction with related instruments such as coronary heart disease non-destructive detectors for detecting human heart sounds and blood vessel sounds. The sound is converted into electrical signals through the acoustic sensor on it. , and then transmitted to the heart sound detection head of the relevant complete machine for analysis and use by wires. Background technique [0002] The heart sound detection head used in the hospital still adopts the traditional, ancient, backward, and uncivilized operation method, that is, to use multiple sticking plasters and adhesive tapes to fix the detection head closely to the detection surface of the person being examined, which is time-consuming. , laborious, unhygienic, causing pollution and pain, and low work efficiency. Moreover, because the wire has no fixed device for positioning, it is easy to be bent an...
