As shown in fig. 1 and 2, the present embodiment provides a carotid artery compressor for an interventional operation for cerebrovascular diseases, which includes a body 1, a compression part 2, a pulse detection device 3, and a compression device 4.
Both ends of the machine body 1 are provided with a pressing part 2, and the machine body 1 and the two pressing parts 2 are surrounded to form an annular structure with an opening at one end.
The inside of the compression unit 2 is provided with a pulse detection device 3 and a compression device 4, and the compression device 4 compresses the pulse beat point according to the detection value of the pulse detection device 3.

The device is a device commonly used in the prior art, and has application on devices such as a smart watch, a blood pressure detector and the like.
The pressing device 4 is a device for pressing the pulse beating point through movement, expansion and contraction and the like, which is a device commonly used in the prior art, and is arranged on a common massage instrument, wherein the difference is that the pressing device in the massage instrument reciprocates according to a certain rule, and the pressing device 4 does not move after applying certain pressure to the pulse beating point to isolate blood flow in the operation process.
In the present embodiment, the pulse beat point is determined by the detection value of the pulse detection device 3, and then the pulse beat point is compressed by the compression device 4, so that the compression position is accurate, the purpose of blocking the blood flow can be truly achieved, and in addition, the pulse beat point is automatically identified and compressed, so that the operation is convenient. And the component parts are fewer, and the structure is simpler.
It should be noted that: the compressor is auxiliary equipment for cerebral vascular interventional operation, judges the pulse beat point through the detection value of the pulse detection device 3, and then compresses the pulse beat point through the compression device 4, so that diagnosis and treatment of diseases are not involved.
The inner side of the machine body 1 is of an arc-shaped structure. The compressor is in the use, and the cover is established at human neck, and organism 1 is laminated with the rear side of neck, and two oppression portions 2 are located the both sides of neck respectively, set up 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 to facilitate the grip of the compressor, the outer side of the machine body 1 may be provided with an arc-shaped structure.
Further, the inside of the pressing part 2 is also of an arc-shaped structure so as to adapt to the curvature of the neck of a human body, in addition, the free ends of the two pressing parts 2 are folded towards the middle, and in the arrangement mode, when the pressing device is sleeved on the neck, a certain clamping force can be provided, and the pressing device is not easy to slip from the neck. It is particularly important that the compression part 2 can be more attached to the neck, so that the detection and compression of the pulse beat point are facilitated.
The inner sides of the machine body 1 and the compression part 2 are made of flexible materials. For example, a cushion is provided at the contact portion of the body 1 and the pressing portion 2 with the neck, so that the comfort of use can be improved.
In the present embodiment, a specific structural form of the compression device 4 is provided, specifically as follows:
the pressing device 4 is a slider that can reciprocate (reciprocate in the circumferential direction of the neck) along the longitudinal direction of the pressing portion 2.
The slider is provided with a pressing head capable of reciprocating in the thickness direction of the pressing part 2. I.e., the pressing head is provided on the slider and is capable of reciprocating in a direction perpendicular to the slider (reciprocating in the radial direction of the neck).
The detected pulse beat point is not fixed in position, and therefore, it is necessary to move the slider to the detected pulse beat point to press it. In addition, since the slider has a problem that the pressing strength against the pulse beat point is low enough to block the blood flow, it is necessary to block the blood flow by moving the pressing head to increase the pressing strength.
In the present embodiment, the driving device for driving the slider and the pressing head is not modified, and the driving device may be a ball screw mechanism, a rack and pinion mechanism, a slider-crank mechanism, or the like which is commonly used in the prior art and driven by a motor.

The pulse sensor has two types of analog output and digital output according to the output mode. The method for collecting signals can be mainly divided into three types of piezoelectric type, piezoresistive type and photoelectric type. In which piezoelectric and piezoresistive materials (piezo-electric plates, bridges, etc.) convert the pressure course of pulse pulses into a signal output. The photoelectric pulse sensor converts the change of the transmittance of the blood vessel in the pulse beating process into signal output by a reflection or correlation mode. The present embodiment preferably employs piezoelectric and piezoresistive pulse sensors.
The pulse sensors are provided on both pressing portions, and are provided along the inner surface of the pressing portion, and 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, along both sides of the movement track of the slider.

Specifically, the remote control device 5 transmits a control signal to the control device, and the control device controls the operation of the pressing device 4 according to the control signal. Of course, the control device may also automatically control the operation of the compression device 4 according to the detection value of the pulse detection device 3.
Specifically, when the pulse detecting device 3 detects the pulse beat strongest point, the 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 coordinates of the pulse beat 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 different gears (such as 1 gear and 2 gear … …) are set on the remote control device 5, the different gears represent different compression forces, when the force is set to be 1 gear, the pulse detection device 3 feeds back that blood flow is fluctuated on the remote control device, then the pressure is increased to 2 gears or even higher gears again until the feedback value of the pulse detection device 3 is 0, and then interventional diagnosis and treatment operation of temporarily blocking carotid blood flow is performed. The process of adding or subtracting the gear may also control the pressing device 4 (specifically, control the expansion and contraction of the pressing head) to automatically operate through the control device.
When the slider is moved to the pulse maximum point and the feedback value of the pulse detection device 3 is 0, the instruction may be made by a corresponding indicator lamp being normally 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 a cerebral vascular disease interventional procedure as described above.
The carotid artery pulsating point is identified by the pulse detection device 3, and then compressed by the compression device 4.
