Intermittent pneumatic compression system with venous refilling detecting function

Abstract

The invention provides an intermittent pneumatic compression system with a venous refilling detecting function, which comprises a system host, a vent line, a limb sleeve and a detection sensor. The system host is connected to the limb sleeve through the vent line. The limb sleeve is used for providing air pressure with certain strength to a limb of a patient according to the control of the system host so as to change the blood circulation state of the limb. The detection sensor is arranged in the limb sleeve and is used for detecting the blood circulation state of the limb in the limb sleeve in real time and transmitting a detection signal to the system host. The system host is used for automatically regulating the operations of inflating and deflating the limb sleeve according to the signal transmitted by the detection sensor. By the intermittent pneumatic compression system provided by the invention, the time interval of pressurizing by air inflation can be controlled and automatically regulated and the blood circulation is well promoted. The intermittent pneumatic compression system is helpful to prevent the deep vein thrombosis from being formed, relieves various symptoms caused by the deep vein thrombosis and performs early warning on the various symptoms and has wide application prospect.

Description

technical field [0001] The invention relates to an air-inflated pressurized medical-rehabilitation device capable of promoting blood and interstitial fluid circulation, and more specifically relates to an intermittent air-inflated pressurized system with the function of venous refill detection. Background technique [0002] Intermittent Pneumatic Compression system is a medical and rehabilitation device that applies a certain intensity of air pressure to the patient's limbs through the limb sleeve at a certain time, position sequence and intermittent interval. It can effectively promote the circulation of blood and interstitial fluid, help prevent the formation of deep vein thrombosis, improve the arterial blood supply of limbs, treat venous edema of limbs and arterial ischemic diseases of lower limbs, and relieve various symptoms caused by them. At present, this type of equipment has two names: air pressure therapy device (IPC) and air pressure anti-thrombotic pump (DVT). ...

AI Technical Summary

Problems solved by technology

At present, the IPC system has been widely used in clinical treatment, but the current IPC system is used for mechanical compression therapy, and the interval between inflation and compression is not adjusted according to the circulation of the patient's limbs, and it exists in conjunction with the actual disease of the patient. Unsatisfactory problems, such as the blood in the patient's limbs may be pressured and emptied again before it is fully recharged, and because the doctor does not have enough information on the circulation level of the limbs and the principle of the equipment, it cannot achieve the best Therapeutic effect

In order to achieve a better therapeutic effect, the interval between inflation and pressurization should be dynamically adjusted according to the circulation of the patient's limbs. In this regard, it is known that the related products of the American Tyco Company have similar functions. Its equipment measures the volume of the patient's limbs in The amount of change after venous refilling is used to control and adjust the time of extremity circulatory pressurization, but in actual trials, it is found that the measurement results are very inaccurate, because the volume of the patient's limbs changes very little after venous refilling, so this device cannot achieve the best therapeutic effect
