Description

Simple external counterpulsation system

This work is related to the technical field of external counterpulsation system, especially a simple external counterpulsation system.

Extracorporeal Counterpulsation (ECP) is a non-invasive medical treatment method that can effectively help blood circulation and improve heart function. It has been used in clinical practice for more than 20 years. It mainly involves tying air bags to the lower limbs of the human body. By inflating the air during the diastole of the heart, the pressure of the aorta is increased, which helps to increase coronary artery perfusion, improve heart blood supply, and reduce the workload of the heart.

In addition, an inflatable leg massager is a home health product that also uses air bags or expansion bags around the legs to inflate and deflate, but it can only be used to provide massage and relief for the legs.

The human vein is an important vascular reservoir, with 64% of the systemic blood in the venous system. Venous return is critical because it must be equal to cardiac output in a stable state. The calf is commonly known as the second heart of the human body because the blood volume in the veins in this area is equal to the heart's output. Sitting for a long time will cause blood to accumulate in the lower body, reducing blood circulation in the legs. This may lead to leg swelling, varicose veins and discomfort.

Driving is also an activity that requires long periods of sitting. Its impact on the human body is the same as long periods of sitting at a desk or long-distance flights. Long-term driving cannot bear the physical load required for driving, which puts a burden on the heart and overall health. It may affect blood circulation and insufficient blood supply to the brain, making drivers more likely to feel tired and mentally exhausted. The physiological response will deteriorate, seriously affecting the safety of the car. The longer a person drives, the more likely he or she will experience fatigue driving. Although fatigue driving accounts for 5% of the types of car accident accidents, the casualties and losses caused by fatigue driving account for as high as 60% of the total car accident accidents.

Although the existing external body counterpulsation (ECP) can effectively help blood circulation, it is large in size and complex to operate. It is mainly used in hospitals or clinics and needs to be monitored and operated by medical professionals. It will generate high-frequency noise and vibration when used, and the pressure will reach 300mmHg, which is even more difficult for the elderly to bear, causing them to give up halfway and fail to complete the 35-week treatment. The traditional inflatable leg massager, although it is light and can be used by individuals at home without the need for monitoring by medical professionals, has a simple massage function and cannot achieve the same effect as external body counterpulsation, so it is very limited in helping to improve blood circulation.

In view of this, the main purpose of this invention is to provide a simple external counterpulsation system, which mainly includes: a leg massager, a human physiological signal detector, an air pressure automatic control unit, and an external counterpulsation application program APP; wherein the leg massager has at least a leg sleeve and an air supply pump, the leg sleeve is provided with a hard shell outer cover covering the calf and an inner air bag, and the air supply pump and the leg sleeve are connected by a pipeline; the human physiological signal detector is installed on the user, and the air supply pump is connected to the leg sleeve by a pipe ... The user's heart rate or breathing rate is monitored in real time, and the air pressure automatic control unit is connected to the air pressure automatic control unit by wired or wireless information transmission; the air pressure automatic control unit is set corresponding to the air supply pump and the leg sleeve, and the air supply pump adjusts the massage rhythm of the leg sleeve to inflate and deflate the air according to the user's real-time monitoring of the heart rate or breathing rate data, and; the external counterpulsation application APP is set corresponding to the air pressure automatic control unit to connect to the cloud to record and analyze the user's human physiological signals and system operation data.

In a preferred implementation, the human physiological signal detector can be a heart rate detector, a heart sound detector, or a breathing detector, but is not limited thereto.

In a preferred implementation, the air pressure automatic control unit may be provided with a corresponding gravity sensor to be installed on the car's driver's seat to monitor the user's body position and movement, but the invention is not limited to this.

Compared with the existing known technologies, the advantages of this simple external counterpulsation system are that the overall structural design is very practical, the system is easy to operate and does not require complicated settings. You only need to wear a leg cuff to start the system, and it can generate effective external counterpulsation massage rhythms based on real-time monitoring of human physiological signals, promote human blood circulation and physical health, improve blood supply to the brain, help users refresh their minds and reduce fatigue, and can especially be used to improve driving safety and reduce accident risks.

Start the system equipment to start operation, so that the air pressure automatic control unit 3 adjusts the massage rhythm of the air supply pump 12 to inflate and deflate the leg sleeve 11 according to the user's real-time monitoring of the heart rate or breathing rate data, and; Step S104. At the same time, use the external counterpulsation application APP 4 to connect to the cloud to record and analyze the user's human physiological signals and system operation data.

The preferred implementation is shown in FIG1 , wherein the human physiological signal detector 2 can be further a heart rate detector 21, having a full-face finger cuff 211, and at least one PPG pulse sensor 212 is arranged inside. The full-face finger cuff 211 can be made of a soft rubber sleeve, so that it has flexibility and can be worn tightly and comfortably. Its greatest feature is that the full-face finger cuff 211 can effectively isolate the external light source of the finger, so that the detection of the internal PPG pulse sensor 212 is more accurate, so as to measure the changes in blood oxygen saturation (SpO2), heartbeat, heart rate variability analysis (HRV), and cardiac output.

In this way, the user's heart rate can be monitored in real time during use, and the air pressure automatic control unit 3 can adjust the inflation/deflation rhythm of the leg massager 1 according to the monitored heart rate to ensure that the leg massager 1 can be inflated during the diastole period, increase the pressure of the aorta to improve the heart's blood supply, and help the heart to pump blood more effectively in each beat, which is then pumped to the organs throughout the body to promote physical health. Photoplethysmography (PPG), blood oxygen saturation monitoring (Pulse oximetry, i.e. SPO2), heart rate variability analysis (heart rate variability, abbreviated as HRV).

In a preferred embodiment, as shown in FIG6 , the human body physiological signal detector 2 can also be further configured as a heart sound detector 22, which at least includes a micro-microphone 220 connected to a micro-computer circuit 221, wherein the micro-computer circuit 221 at least has a preamplifier 222, a filter amplifier 223, and an A/D linear digital converter 224 to process the patient's heart sound source signal captured by the micro-microphone 220; A signal processing unit 225 and a signal analysis unit 226 are built into the circuit 221 to perform intelligent analysis and model building on the collected heart sound source signals, wherein the signal analysis unit 226 models the effective heart sound event signal, and the modeling reference is taken from two data, one is the big data of the majority of heart sound evidence data, and the other is the patient's own heart sound evidence data, so as to obtain a personalized and accurate modeling of the heart valve opening sound signal.

Thus, by monitoring the user's breathing rhythm, the system can adjust the inflation/deflation rhythm of the leg massager 1 to ensure that the massage is synchronized with the breathing, so that the leg massager 1 can be inflated during the exhalation period of the lungs. This can also promote the health of human blood circulation and improve the blood supply to the brain, helping the user to refresh the mind and reduce fatigue.

The preferred implementation is shown in FIG3 , where the air pressure automatic control unit 3 can also be further provided with a corresponding G-Sensor gravity sensor 31 to be installed on the car driver's seat 30 to monitor the user's body position and movement. When the system detects that the user's body position is improper or too still, the blood circulation may be affected due to long-term driving, and the blood supply to the brain is insufficient, resulting in mental fatigue and lack of concentration. At this time, the system can be activated to strengthen the external counterpulsation to promote blood circulation, improve blood supply to the brain, reduce fatigue and boost spirits to improve driving safety.

As shown in Figures 1 to 5, it is particularly worth mentioning that the leg massager 1 of the invention is designed as a lightweight leg sleeve 11, so it can be worn and used at any time.

It does not require too much pressure to achieve the effect of cardiac counterpulsation, so that the blood perfusion efficiency can be optimized, and at the same time, it can also achieve the purpose of "reducing vibration" and "eliminating noise".

Specific applications: 1. Wrap the leg sleeve 11 around the user's calf. 2. At the same time, the full-face finger sleeve 211 is mounted on the user's fingertips, and the internal PPG pulse sensor 212 is used to measure changes in blood oxygen saturation (SpO2), heart rate, HRV, and cardiac output. Inflation and deflation are performed based on changes in heart rate. 3. The air bag 112 in the leg sleeve 11 is filled with 250~300mmHg gas from bottom to top with a time difference of 50ms to pressurize the calf, drive the blood in the lower limbs to flow back to the heart, and increase the coronary artery blood flow to the myocardium. 4. Then the air bag 112 in the sleeve is quickly deflated to release the compressed blood vessels in the lower limbs, thereby reducing the heart load.

The effective structure of this invention can reduce the pressure by 30% compared with the known external counterpulsation system, that is, the counterpulsation effect can be achieved, and the vibration can be reduced by 15% compared with the known external counterpulsation system, and the noise can be reduced by 10dB, that is, it can overcome and improve the shortcomings of the existing external counterpulsation and inflatable leg massager 1 in application, and can enhance the effect of external counterpulsation, so as to achieve the purpose of promoting blood flow and improving blood circulation.

Compared with the existing known technology, the advantages of the simple external counterpulsation system 100 and the application method of this invention are that the overall structural design is very practical, the system is easy to operate and does not require complicated settings. Just wear the leg sleeve 11 to start the system, and it can generate effective external counterpulsation massage rhythm according to real-time monitoring of human physiological signals, promote human blood circulation and physical health and improve brain blood supply, help users refresh their minds and reduce fatigue.
