As shown in fig. 1, one embodiment of the present application provides a blood flow monitoring device, which includes a treatment device 100 and a main control device 200.
The treatment device 100 is used for performing freezing fat-reducing treatment by being adsorbed on the skin surface and refrigerating. In this embodiment, the treatment device 100 may be a vacuum suction handle. Treatment device 100 includes a housing 110, a cooling surface 120, and a detection module 130.
The housing 110 is used to form a treatment chamber to accommodate a treatment area on the skin, the surface of the housing 110 may be arc-shaped, and the material of the housing 110 may be plastic.
The cooling surface 120 is disposed inside the housing 110, and the shape of the cooling surface 120 is fitted to the shape inside the treatment chamber for cooling, so that the adipocytes are crystallized at low temperature to start the apoptosis process. In this embodiment, the cooling surface 120 may be a flexible panel or a rigid panel. Research shows that low temperature can promote subcutaneous fat cells to crystallize and start apoptosis, and the apoptotic fat cells are exhausted by the immune system and are not retained in vivo, so that local fat reduction can be realized by adopting the cooling surface 120 for local refrigeration.
The detection module 130 may be disposed between the cooling surface 120 and the housing 110, as shown in fig. 1, or the detection module 130 may be embedded in the cooling surface 120, as shown in fig. 2. The detection module 130 may detect the blood flow velocity of the treatment region by means of sound or light or a combination of both. Specifically, the detecting unit 130 emits an acoustic wave signal or a light wave signal to detect the blood flow, and the acoustic wave signal or the light wave signal is scattered when being transmitted to the red blood cells in the blood vessel. During scattering, the red blood cells become a new sound source or light source, and emit sound wave signals or light wave signals to the periphery. The detection module 130 is provided with a receiver therein for receiving the signal reflected by the red blood cells and analyzing the signal to detect the blood flow velocity. Further, the treatment device 100 may further include an anti-freezing film 140, wherein the anti-freezing film 140 is disposed on a surface of the cooling surface 120 facing the skin, and is used for preventing the skin from being frostbitten due to the low temperature of the cooling surface 120. Since the detection module 130 optically detects the blood flow velocity, the light wave signal needs to pass through the anti-freezing film 140, and thus the anti-freezing film 140 in this embodiment may be made of a light-transmitting material, such as silk or plant fiber.
The main control device 200 is communicatively connected to the treatment device 100, and is configured to receive the blood flow velocity detected by the treatment device 100 and generate a control command according to the blood flow velocity.

The blood flow monitoring device provided by the embodiment comprises the detection module 130, the detection module 130 detects the subcutaneous blood flow speed in a sound and/or light mode, the detection precision is high, the anti-freezing film only can influence the temperature, and the sound waves and the light waves cannot be influenced, so that the accuracy of the detection result can be improved, and the safety and the effectiveness of the treatment device can be further improved.
In one embodiment, the instruction execution module 300 may be disposed on the treatment device 100, or the instruction execution module 300 may be disposed on the main control device 200. In this embodiment, the instruction execution module 300 may include a start/stop button, an alarm unit, and the like.

The laser emitting end emits laser to the treatment area, red blood cells in blood reflect or scatter the laser, and the laser receiving end is used for receiving the laser reflected by the red blood cells. The detection module 130 is internally provided with an arithmetic unit, and the arithmetic unit analyzes the reflected laser power spectrum, converts the laser power spectrum into an electric signal, and calculates the blood flow velocity at the current moment through analog-to-digital conversion after filtering and amplification.
When the detection module 130 includes an ultrasonic doppler probe, the ultrasonic transmitting end transmits ultrasonic waves to the treatment region, the ultrasonic waves are scattered by red blood cells in blood, and after the ultrasonic receiving end receives the scattered ultrasonic signals, the operation unit performs analysis operation on the received ultrasonic signals to obtain the blood flow velocity at the current moment.
When the detection module 130 includes an optical camera, the optical camera is used to shoot a microvascular microscopic image, a blood vessel center line is extracted, and the flow velocity of blood is calculated by counting the time-varying property of the center line of the frame sequential image.
When the detection module 130 includes a plurality of laser doppler probes, ultrasonic doppler probes, and optical cameras, the average value of a plurality of detection results can be used as the blood flow velocity at the current time, which can improve the detection accuracy.
In one embodiment, referring to fig. 3, the main control device 200 includes a control module 210, and the control module 210 is communicatively connected to the detection module 130. The detection module 130 includes an operation unit 131, and the control module 210 includes a comparison unit 211 and an instruction generation unit 212. The operation unit 131 is configured to calculate a blood flow velocity variation at preset time intervals, and send the blood flow velocity variation to the control module 210. The comparing unit 211 in the control module 210 compares the blood flow rate variation with a pre-stored threshold, and generates a control command according to the comparison result, so that the command executing module 300 executes a corresponding action.
The control module 210 has a first threshold and a second threshold stored therein. When the cryotherapy is started, the operation unit 131 calculates a first variation of the blood flow velocity within a preset time interval Δ t, and sends the first variation to the control module 210. The method for detecting the blood flow velocity by the detection module 130 is described above, and the operation unit 131 obtains the blood flow variation by subtracting the maximum value and the minimum value of the detected blood flow velocity within the preset time interval Δ t.

If the first variation is smaller than the first threshold, indicating that there is blood perfusion, that is, the treatment device 100 does not complete vacuum adsorption, the instruction generating unit 212 generates an alarm instruction, and the instruction executing module 300 controls to issue an alarm or prompt re-adsorption according to the alarm instruction, wherein the instruction executing module 300 includes an alarm unit, and the alarm unit may be installed on the treatment device 100 or the main control device 200.
If the therapeutic device 100 successfully adsorbs, i.e., after refrigeration is started, the control module 210 is further configured to record refrigeration time, the comparison unit 211 determines whether the refrigeration time reaches a preset time, and if the refrigeration time reaches the preset time, the instruction generation unit 212 generates a refrigeration stop instruction, so that the instruction execution module 300 stops refrigeration and prompts the end of therapy, and meanwhile, the control module 210 records therapy data.
If the refrigerating time does not reach the preset time, the operation unit 131 calculates a second variation of the blood flow rate at preset time intervals Δ t during the treatment process, and sends the second variation to the comparison unit 211. The comparison unit 211 compares the second variation with a second threshold. If the second variation is greater than or equal to the second threshold, it indicates that blood perfusion occurs during the treatment process, that is, the treatment device 100 falls off during the treatment process, the instruction generating unit 212 generates an alarm instruction, the instruction executing module 300 sends an alarm according to the alarm instruction, and the control module 210 stores data, such as the cooling time, the blood flow speed, and the like. If the second variation is smaller than the second threshold, it indicates that no perfusion occurs during the treatment process, i.e., the treatment device 100 does not fall off, the treatment device 100 continues to cool until the cooling time reaches the preset time or the second variation is greater than or equal to the second threshold. In this embodiment, values of the first threshold and the second threshold may be determined according to actual conditions.

s100: the blood flow velocity is detected acoustically and/or optically.
The treatment device is first activated and includes a detection module that detects blood flow velocity either acoustically or optically or a combination thereof. The detection module can comprise any one or more of a laser Doppler probe, an ultrasonic Doppler probe and an optical camera.
The detection module further comprises an operation unit, and the operation unit is used for calculating the blood flow speed variation at preset time intervals.
S200: and generating a control command according to the blood flow velocity.
The main control device generates a control command according to the blood flow velocity. Specifically, the main control device comprises a control module, and the control module comprises a comparison unit and an instruction generation unit. The comparison unit is used for comparing the blood flow variation in the preset time interval with the threshold value, and the instruction generation unit generates the control instruction according to the comparison result.
S300: and receiving a control instruction and executing a corresponding action.
The instruction execution module receives the control instruction and executes corresponding actions, such as starting refrigeration, stopping refrigeration, giving an alarm or prompting information and the like.

Specifically, referring to fig. 5, the detection unit detects the blood flow velocity when the treatment apparatus is activated. The operation unit calculates a first variable quantity of the blood flow speed in a preset time interval and sends the first variable quantity to the control module. The comparison unit compares the first variation with a first threshold, if the first variation is larger than or equal to the first threshold, the blood perfusion is blocked, namely the vacuum adsorption of the treatment device is completed, a refrigeration instruction is generated, and the instruction execution module starts refrigeration. If the first variable quantity is smaller than the first threshold value, the blood flow perfusion is indicated, namely the treatment device does not complete the vacuum adsorption, and the instruction generation unit generates an alarm instruction.
After the refrigeration is started, the control module records the refrigeration time and judges whether the refrigeration time reaches the preset time. If the refrigeration time is up, the instruction generation unit generates a refrigeration stopping instruction, the instruction execution module stops refrigeration and prompts the end of treatment, and meanwhile, the control module records treatment data. If the refrigerating time is not reached, the operation unit calculates a second variation of the blood flow speed at preset time intervals and sends the second variation to the comparison unit. The comparison unit compares the second variation with a second threshold. If the second variable quantity is larger than or equal to the second threshold value, the occurrence of blood perfusion in the treatment process is indicated, namely the treatment device falls off in the treatment process, and the instruction generating unit generates an alarm instruction. While the control module stores data such as refrigeration time, blood flow rate, etc. If the second variation is smaller than the second threshold, it indicates that no perfusion occurs during the treatment process, i.e., the treatment device does not fall off, the treatment device 100 continues to cool until the cooling time reaches the preset time or the second variation is greater than or equal to the second threshold.
