Abstract: A mobile respirator has a respiratory device, a pipe, a breathing component, and a power bank. The pipe has two opposite ends respectively connected to the respiratory device and the breathing component, and the power bank is electrically connected to the respiratory device. A user can place the power bank and the respiratory device inside a backpack, and the pipe can be outstretched from the backpack. Thereby, the user can carry the backpack and wear the breathing component, so the user may breathe with assistance of the mobile respirator. By the power bank supplying electricity for the respiratory device, the mobile respirator is mobile outdoors and solves the trouble of dyspnea while exercising or staying outdoors.

Abstract: A continuous positive airway pressure device has a shell, a diversion sound-absorbing foam pad, a blower, and a partition. The shell has an inlet and an outlet. The diversion sound-absorbing foam pad is disposed inside the shell and forms an airflow passage extending tortuously inside the shell. The blower is disposed on the diversion sound-absorbing foam pad and fluidly communicates with the airflow passage and the outlet of the shell. The partition covers the blower and the diversion sound-absorbing foam pad and has a leading hole fluidly communicating with the airflow passage and the inlet of the shell. After air flows into an interior space of the shell, the air flows through the airflow passage being tortuous and then flows out from the shell, which lengthens flow path of the air, reduces noises generated during the air flowing, and helps the air to flow more fluently.

Abstract: A blower includes an upper housing and a lower housing. An air flow space and an air outlet passage are formed inside and communicate with each other. A fan is mounted in the upper housing and the lower housing. A driving shaft of a motor passes through the lower housing and is connected to the fan. The upper housing has a first annular rib with an arc-shaped surface at an edge of the air inlet opening. The upper housing has a second annular rib protruding on an inner bottom surface of the upper housing and adjacent to the air inlet opening. When an external fluid flows in the air inlet opening, the fluid can smoothly pass through the arc-shaped surface of the first annular rib. A part of the fluid is blocked by the second annular rib, and thus forms a vertical downward airflow curtain.

Abstract: A negative pressure protection system has a cover enclosing an inner space, a ventilation duct fluidly communicating with an air outlet port of the cover, a filter having an inlet end communicating with the ventilation duct, and an air exhausting device connected to an outlet end of the filter. The air exhausting device draws air out from the inner space of the cover via the ventilation duct. The air is filtered and purified by the filter and then is exhausted away by the exhausting device.

Abstract: A non-invasive continuous blood pressure monitoring system includes a first sensor configured to send a first ultra-wideband electromagnetic pulses to an upper site of a blood vessel and receive a first reflected ultra-wideband electromagnetic pulses with phase variations caused by a pressure wave propagating in the blood vessel, a second sensor configured to send a second ultra-wideband electromagnetic pulses to a lower site of the blood vessel and receive a second reflected ultra-wideband electromagnetic pulses with phase variations caused by the pressure wave propagating in the blood vessel, and a signal-processing and blood pressure displaying device configured to calculate an estimated blood pressure by taking into consideration a propagation time of the pressure wave from the upper site to the lower site in the blood vessel.

Abstract: A nose cap includes a hollow body having a first opening, a second opening communicating with the first opening via a first passage and an outer covering having a third opening communicating with the first opening of the hollow body and a fourth opening communicating with the third opening via a second passage. An air chamber is formed between the hollow body and the outer covering after extension of the hollow body into the second passage. The air chamber is able to provide comfort to a patient.

Abstract: An air flow measurement device includes an air pipe securely formed inside the cylindrical tube, a first measuring tube securely formed inside the cylindrical tube and having a first open end located at an inner side face of the air pipe so as to measure radial pressure of air flowing through the air pipe and a second open end extending out of the cylindrical tube. An L shaped measuring tube is securely formed inside the cylindrical tube and has a first open end located at the inner side face of the air pipe so as to measure axial pressure of air flowing through the air pipe and a second open end extending out of the cylindrical tube.
