The device is a common device in the prior art, and is applied to equipment such as an intelligent watch, a blood pressure detector and the like.
The compression device 4 is a device for compressing the pulse pulsation point through movement, extension and the like, and is a device commonly used in the prior art, the device is arranged on a common massage instrument, the difference is that the compression device in the massage instrument reciprocates according to a certain rule, and the compression device 4 does not move after applying a certain pressure to the pulse pulsation point to cut off blood flow in the operation process.
In the embodiment, the pulse pulsation point is judged according to the detection value of the pulse detection device 3, and then the pulse pulsation point is compressed by the compression device 4, so that the compression position is accurate, the purpose of blocking blood flow can be really achieved, in addition, the pulse pulsation point is automatically identified for automatic compression, and the operation is convenient. And the component parts are fewer, and the structure is simpler.
It should be noted that: the compressor is an auxiliary device for cerebrovascular intervention operation, judges the pulse pulsation point according to the detection value of the pulse detection device 3, and compresses the pulse pulsation point through the compression device 4, and does not relate to diagnosis and treatment of diseases.
The inner side of the machine body 1 is of an arc structure. The compressor is in the use, and the cover is established at human neck, and organism 1 laminates with the rear side of neck, and two oppression portions 2 are located the both sides of neck respectively, set the inboard of organism 1 into the arc structure, accord with human neck comfort level design, accord with human neck curvature. Of course, in order to improve the comfort of the compressor or facilitate the holding of the compressor, the outer side of the machine body 1 may be provided with an arc-shaped structure.
Further, the inboard of oppression portion 2 also is the arc structure to adapt to human neck curvature, in addition, the free end of two oppression portions 2 draws in the setting in to the centre, and this kind of mode of setting can provide certain clamping-force when the compressor cover is established at the neck, is difficult to follow the neck slippage. Particularly, the pressing part 2 can be more attached to the neck, so that the pulse beating point can be conveniently detected and pressed.
The inner sides of the body 1 and the pressing part 2 are made of flexible materials. For example, a soft pad is provided at a portion of the body 1 and the pressing portion 2 contacting the neck, so that the comfort of use can be improved.
In the present embodiment, a specific structure form of the compression device 4 is provided, specifically as follows:
the pressing device 4 is a slider that can reciprocate in the longitudinal direction of the pressing section 2 (reciprocate in the circumferential direction of the neck).
The slider is provided with a pressing head which can reciprocate along the thickness direction of the pressing part 2. That is, the pressing head is provided on the slider and can reciprocate in a direction perpendicular to the slider (reciprocate in the radial direction of the neck).
Since the position of the detected pulse point is not fixed, the slider needs to be moved to the detected pulse point to press the pulse point. In addition, since the slider has a problem that the pressing strength of the slider against the pulse point is not sufficiently low to block the blood flow, the blood flow needs to be blocked by moving the pressing head so as to increase the pressing strength.
In the present embodiment, a driving device for driving the slider and the pressing head is not modified, and a ball screw mechanism, a rack and pinion mechanism, a slider-crank mechanism, and the like, which are commonly used in the related art and driven by a motor, may be used as the driving device.

The pulse sensor has two output modes of analog output and digital output. The method can be mainly divided into a piezoelectric type, a piezoresistive type, a photoelectric type and the like according to the signal acquisition mode. The piezoelectric type and the piezoresistive type convert the pressure process of pulse pulsation into signals and output the signals through micro-pressure type materials (piezoelectric sheets, bridges and the like). The photoelectric pulse sensor converts the change of the light transmittance of the blood vessel in the pulse beating process into a signal to be output in a reflection or correlation mode. The present embodiment preferably employs piezoelectric and piezoresistive pulse sensors.
In addition, in order to improve the detection accuracy, a plurality of pulse sensors are provided on both sides of the inner surface of the pressing portion 2, that is, a plurality of pulse sensors are provided along both sides of the movement locus of the slider.

The remote control device 5 and the control device can be connected through Bluetooth, and the control distance of the remote control device 5 is 10 m.
The control device is internally provided with a power supply device, a processor, a data transmission device and the like, can supply power to the compressor, receives external control signals, processes the data of the pulse detection device according to a preset program in the processor, and controls the operation of the compressor according to a processing result.
Specifically, the remote control device 5 sends a control signal to the control device, and the control device controls the operation of the compression device 4 according to the control signal. Of course, the control device may automatically control the operation of the compression device 4 based on the detection value of the pulse wave detection device 3.
Specifically, when the pulse detection device 3 detects the pulse strongest point, the remote control device 5 controls the slider to move to the point, or the control device automatically controls the slider to move to the point according to the position coordinate of the pulse strongest point.
The remote control device 5 can display the detection value of the pulse detection device 3 and adjust the compression force of the compression device 4. If, set up different gears (like 1 shelves, 2 shelves … …) on remote control unit 5, different gears represent different oppression dynamics, and when setting up to 1 gear dynamics, pulse detection device 3 feedback still has blood flow fluctuation on the remote controller, just pressurize again to 2 gears or even higher gears, until pulse detection device 3 feedback value is 0, later carry out the intervention of blocking the carotid blood flow temporarily and diagnose the operation. The process of increasing or decreasing the shift position may be automatically performed by controlling the pressing device 4 (specifically, controlling the extension or contraction of the pressing head) by the control device.
When the slider is moved to the pulse strongest point and the feedback value of the pulse wave detection device 3 is 0, the indication may be performed by a method such as a corresponding indicator lamp being constantly on.
In the present embodiment, there is also provided a carotid artery compression method for compressing a carotid artery using the carotid artery compressor for cerebrovascular disease interventional procedures as described above.
The carotid pulsation point of the carotid artery is identified by the pulse detection device 3, and then is compressed by the compression device 4.
Specifically, a plurality of carotid pulsation points identified by the pulse detection device 3 are compared, and the strongest point of the carotid pulsation is selected; the compression device 4 compresses the strongest point of the carotid artery pulse.
