Expansible gas delivery system and gas delivery method

Abstract

An expansible gas delivery system and a gas delivery method are disclosed. The system comprises a PAP device and a sensing control device, wherein, the PAP device comprises an air flow generator for providing breathable air to a patient, a processor for providing a control signal to the air generator, and a digital transmission module controlled by the processor; while the sensing control device comprises at least a sensor used for obtaining physiological information from the patient, a processor used for receiving the physiological information from the sensor and thereby generating a data signal, and a digital transmission module controlled by the processor, wherein, the PAP device and the sensing control device carry out digital communication through the respective digital transmission module to transmit the data signal to the PAP device and control the air supply action of the air generator through the data signal. The invention can approach closer to the demand of the user, thus achieving the effect of one machine multiple purposes.

Description

technical field [0001] The present invention relates to a gas delivery system and a gas delivery method for treating respiratory-related diseases, in particular to an expandable gas delivery system that can flexibly increase or decrease physiological signal sources according to different needs, and then obtain an optimal gas delivery pressure range and methods. Background technique [0002] Obstructive Sleep Apnea Syndrome (OSAS) is known as a breathing disorder caused by the collapse or narrowing of the upper airway during sleep. Due to the continuous emergence of related research on sleep physiology over the years, The medical community has also had a considerable degree of understanding of OSAS. [0003] The CPAP (Continuous Positive Airway Pressure, continuous positive airway pressure) system developed in the 1980s is currently the most important way to treat OSAS. Continuous positive pressure to keep the patient's airway open and avoid obstruction caused by muscle col...

Problems solved by technology

[0005] Regardless of the improvement of any CPAP device, the most important behavior is to change the gas pressure supplied to the patient according to the patient's breathing changes. The main reason is that if the gas pressure provided is not appropriate, it is very likely to cause unexpected For example, if the pressure provided is too small, it will not be able to achieve the effect of maintaining the smooth breathing airway. If the pressure provided is too high, it will not only make the user feel uncomfortable, but also likely to cause leakage. gas, or make the patient arousal during sleep, which will affect the patient's sleep. In addition, the oversupply of gas may also cause some side effects. Therefore, the improvement goal of most CPAP devices in terms of gas delivery pressure is , providing the minimum effective pressure value that meets the needs of the patient, thereby improving the comfort of the patient during use, for example, US6,349,724 is an improvement related to this aspect

[0006] However, as can be seen from the above, each PAP (Positive Airway Pressure, positive airway pressure) device has its fixed hardware configuration, and the functions it can provide are also limited by this hardware configuration. For example, when the user When different needs arise, for example, when the physiological state changes, it may be necessary to accept treatment that cannot be adjusted in real time due to the inelastic hardware configuration

As for the improvement in this aspect, US2007 / 0193583 has increased the gas delivery mode through program setting, and US2007 / 0023045 has provided the possibility of changing the hardware. In addition, US 6,397,845 and US 7,204,250 are through Physiological signals are converted to the patient's sleep stage as a basis for adjusting gas delivery, but in any case, the user's choice of use is still limited by the hardware
