The alarm 70 will issue a warning when output pressure of the compression assembly 10 , as sensed by the sensor 40 , reaches a limit value. Method for measuring blood pressure and pulse rate with a pump-less mechanical compression apparatusPatent 6939306 Method for measuring blood pressure and pulse rate with a pump-less mechanical compression apparatus A method for measuring blood pressure and pulse rate with a pump-less mechanical compression apparatus, wherein the pump-less mechanical compression apparatus comprises a compression assembly with a closed system air bag having a fixed air volume fastened on the human body measuring site; a sensor coupled to the air bag for garage plan shelf storage sensing pressure change inside the air bag; a processor for processing the pressure change; and a display. Also, the mainspring 17 , being connected to the arc walls 111 and annular seat 11 , is coiled during the pressure exertion process for storing elastic energy. As a result, the compressed states of the air bag 20 and thus the wrist of the person are changed to the uncompressed states by the release of the stored elastic force of the mainspring 17 if a person feels uncomfortable during the blood pressure measuring process. . The typical electronic sphygmomanometer is characterized in that an air bag is inflated by a pump, then pressure of the air bag is slowly released by a pressure release device, a sensor is deformed due to the pressure change inside the air bag, the differential electrical resistance of the sensor is then measured by the Wheatstone bridge, and finally a blood pressure is displayed.In the pressure exertion process, the turning member 16 rotates a number of times. A method for measuring blood pressure and pulse rate with a pump-less mechanical compression apparatus, comprising the steps of: fastening an air bag, which is a closed system with fixed air volume, on the human body; activating a compression assembly to exert pressure on the closed system air bag and onto the human body; releasing pressure for returning the air bag to its original state for causing a pressure change inside the air bag and transmitting the pressure change to a sensor for calculating a value; sending the value to a processor for processing in order to obtain a blood pressure including a contraction pressure and a dilation pressure, and a pulse rate; and showing the contraction pressure, the dilation pressure, and the pulse rate on a display. 3A and 3B are cross-sectional views of the pump-less mechanical compression sphygmomanometer/sphygmometer of the invention for illustrating the expanded and the contracted states of the closed system air bag respectively; FIGS. Step e: Contraction pressure, dilation pressure, and pulse i have big ball rate are transmitted from the processor 50 to the display 60 for showing in a digital form. The pressure change inside the air bag 20 is transmitted to the sensor 40 through the duct 80 which is coupled to and connected between the air bag 20 and the sensor 40. Hence, a need for improvement exists. 5, the pump-less mechanical compression apparatus applied on a sphygmomanometer/sphygmometer comprises a fastening device 30 having an air bag 20 , which is a closed system with fixed air volume, fastened at the measuring site (e. During decompression, the compression assembly 10 is adapted to gradually return to its original state and thus the pressure on the air bag 20 is decreased. Note that all of the contraction pressure and dilation pressure, and the pulse rate are measured during the decompression (deflating) process of the air bag 20. As such, rotation of the toothed section 152 of the gear 15 is not stopped by the shaft 181. Step d: The value is sent from the sensor 40 to the processor 50 for processing in order to obtain a corresponding blood pressure including a contraction pressure and a dilation pressure, and a pulse rate. 6 is a flow chart illustrating a process according to the invention. 4A and 4B, the operation of the deactivation assembly 19 is described below.

The sphygmomanometer comprises a processor, an air pump controlled by the processor for pumping air into an air bag until a predetermined pressure is reached, a slow pressure release device is adapted to release pressure of the air bag, and other associated devices (e. As defined, pulse is the regular beating in the arteries caused by the contraction and the dilation of the heart. |
