An apparatus and method for non-invasive and continuous measurement of respiratory chamber volume and associated parameters including respiratory rate, respiratory rhythm, tidal volume, dielectric variability and respiratory congestion. In particular, a non-invasive apparatus and method for determining dynamic and structural physiologic data from a living subject including a change in the spatial configuration of a respiratory chamber, a lung or a lobe of a lung to determine overall respiratory health comprising an ultra wide-band radar system having at least one transmitting and receiving antenna for applying ultra wide-band radio signals to a target area of the subject's anatomy wherein the receiving antenna collects and transmits signal returns from the target area.

A system and method for assessing treatment effects on obstructive sleep apnea are provided. The apparatus includes a bio-signal measurement unit, a combined index calculation unit, and a treatment response assessment unit. The bio-signal measurement unit measures each of the electrocardiogram and respiratory rhythm of a patient. The combined index calculation unit calculates a combined cardiac and respiratory index by combining the heart rate variability and respiratory rhythm signals measured by the bio-signal measurement unit. The treatment response assessment unit assesses a response of the patient to the treatment of obstructive sleep apnea.

The invention discloses a digital respiration-following oxygen supply system, comprising: a respiration rhythm sensor, a height sensor, a microcontroller, a D / A converter and a proportional valve, the input ends of the microcontroller are respectively connected to the height sensor and the respiration rhythm sensor, The proportional valve communicates with the oxygen source and the oxygen mask through the oxygen pipeline. The invention also discloses an oxygen supply method of a digital breathing following oxygen supply system, which includes the following steps: detecting the breathing depth P of the human lung; detecting the breathing cycle T of the human lung; The mathematical model in the processor calculates the pulmonary ventilation Flow∑ and the required oxygen flow Flow (O2); the microcontroller converts the obtained pulmonary ventilation Flow∑ and the required oxygen flow Flow (O2) into electrical signals and sends them to D / A converter: use the D / A converter to control the opening degree of the proportional valve according to the strength of the electrical signal. Improve the utilization rate of oxygen and the comfort of oxygen users.

The invention relates to a respiratory mask which is in line with the ergonomic design and an design method thereof, including a mask body with the facial three-dimensional characteristics, the respiratory mask is characterized in that: the mask body has 28 physiological characteristic points and product characteristic points, the contact position of the mask body and the face forms a three-dimensional characteristic curve, the middle transition part of the mask body is a curve, a respiratory rhythm, an alarm indicator and an anti-gas leak partition board are arranged on the respiratory mask.The respiratory mask extracts the characteristic points to establish the three-dimensional characteristic curve according to a human face three-dimensional model, the mask is closely attached to the face, and the oppression on the face is reduced simultaneously, therefore the respiratory mask is applicable to those who need the long-term non-invasive respiration for usage.

The invention discloses a respiratory muscle training system in an exercise state and a method for using the same, comprising a wearable respiratory monitoring module, an interactive display module, exercise equipment and a respiratory training management system. The wearable respiratory monitoring module monitors the subject's respiratory rate, respiratory flow rate, respiratory flow, heart rate and other parameters in real time through the flow sensor and ECG electrodes, and transmits them to the interactive display module; the interactive display module receives the training mode issued by the training management system, The training parameters are compared with the breathing and heart rate information obtained from the wearable breathing monitoring module, and the subject is reminded to adjust the breathing rhythm and breathing depth in real time; the exercise equipment is used to assist the subject to maintain breathing training under the set exercise intensity, It is helpful to improve the training effect; the respiratory training management system is a management tool for rehabilitation physicians to issue training programs. It is used to formulate respiratory training plans, set differentiated training parameters, track and manage data during respiratory training, and realize continuous optimization of respiratory training programs.

The invention discloses a conveniently aerosolized respiratory medicine oxygen mask which comprises a mask body. A PLC (programmable logic controller) is mounted on the left side surface of the mask body, an oxygen spraying cover and an expiration cover are arranged in the middle of the mask body, an oxygen sensor is mounted on the right side surface of the mask body, and a connecting pipe is fixed on a left inlet of the oxygen spraying cover. The conveniently aerosolized respiratory medicine oxygen mask is simple in structure, oxygen is supplied by the oxygen spraying cover, medicines are supplied by a spraying pipe, treatment can be achieved through the medicines when the oxygen is supplied, medical negligence caused by escape of the mask is avoided, the content of the oxygen in the maskis calculated by the oxygen sensor, the oxygen and the medicines are supplied according to respiratory rhythms of a patient, so that the medicines are inhaled a human body when the patient inhales the oxygen, treatment effect is ensured, the medicines directly enter a nasal cavity through the spraying pipe and cannot be discharged out of the mask along with expiration of the patient, waste of themedicines is avoided, the mask is convenient to use, treatment effect is improved, and rehabilitation of the patient is accelerated.
