Publication number: 20230347092Abstract: 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.Type: ApplicationFiled: April 17, 2023Publication date: November 2, 2023Applicant: GrowTrend Biomedical Co., Ltd.Inventors: Pei-Yin OU, Ching-Liang YU, Yun-Yueh LIU, Neng Yu PAN

Publication number: 20230338678Abstract: 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.Type: ApplicationFiled: April 14, 2023Publication date: October 26, 2023Applicant: GrowTrend Biomedical Co., Ltd.Inventors: Chin-Ni LEE, Pei-Yin OU, Neng Yu PAN, Ching-Liang YU

Publication number: 20230279870Abstract: 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.Type: ApplicationFiled: March 6, 2023Publication date: September 7, 2023Inventors: Chin-Ni LEE, Neng Yu PAN, Ching-Liang YU

Publication number: 20210353484Abstract: 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.Type: ApplicationFiled: December 3, 2020Publication date: November 18, 2021Applicant: GrowTrend Biomedical Co., Ltd.Inventors: Ching-Liang YU, Pei-Yin OU, Yun-Yueh LIU, Neng Yu PAN

Publication number: 20160081631Abstract: A respiratory waveform recognition method comprises: (a) detecting a respiratory airflow in a respiratory cycle; (b) measuring an amplitude of the respiratory airflow and a duration of the respiratory cycle; (c) using a plurality of sampling points to determine an inspiration waveform and an expiration waveform according to the amplitude and the duration; (d) normalizing the amplitude and the duration of one of the inspiration waveform and the expiration waveform, so as to establish a normalized waveform; and (e) accumulating the differences between the normalized waveform and a reference waveform to calculate a flow index useful for the identification of a normal respiration state and an abnormal respiration state. A curve, such as a weighted curve or a standard waveform, is used for fitting of the inspiration waveform or the expiration waveform to calculate the differences, and the differences are accumulated to identify the normal respiration state and the abnormal respiration state.Type: ApplicationFiled: September 23, 2014Publication date: March 24, 2016Inventors: Kang-Ping LIN, Geng-Hong LIN, Hao-Yu JAN, Sheng-Cheng HUANG, Po-Chung SHIN, Ching-Liang YU, Da-Long LEE

Publication number: 20110009784Abstract: A compression device for medical treatment includes an upper colloid sheet, a lower colloid sheet, and a plurality of gas ports. The upper colloid sheet is stacked with the lower colloid sheet and welded, so as to form a plurality of isolated cells with welded walls, and each cell respectively corresponds to one of the gas ports. Therein, the welded walls that neighbors each cell extend diagonally along an angle that is between an x-axis direction and an y-axis direction, so that the welded walls extends from an edge of the upper colloid sheet and the lower colloid sheet to another edge of the upper colloid sheet and the lower colloid sheet. Per aforementioned, the compression device for medical treatment has diagonally formed cells, which results in compression from two directions, so that the medical benefits are increased.Type: ApplicationFiled: July 13, 2009Publication date: January 13, 2011Inventors: Li-Ling Li, Yao-Ming Cheng, Ching-Liang Yu
