The present invention relates to a portable sphygmomanometer.
High blood pressure is a very common condition in modern society. It has been estimated that one in five Americans, around 50 million people, suffer from high blood pressure. In general, more men than women have high blood pressure, and the number of sufferers of both genders increases rapidly with age.
The majority of people with high blood pressure has no symptoms, but if left untreated high blood pressure can lead to major health problems. Consequently the monitoring of blood pressure is vitally important in order to detect cases of high blood pressure and treat them early before health problems can develop.
The conventional sphygmomanometer that functions to measure blood pressure by placing the cuff band on the upper arm has been mainly used. However, the traditional sphygmomanometer is huge and inconvenient. The users cannot measure their blood pressure wherever they need to.
The present invention provides a portable hydraulic sphygmomanometer, comprising (a) a hydraulic belt; (b) a pressure sensor operably linked to the hydraulic belt for detecting the pressure of hydraulic belt; and (c) a computer device for calculating the pressure.
The present invention further provides a method for measuring blood pressure, comprising (a) providing a user with the previously mentioned sphygmomanometer and wearing on one hand; (b) pushing a button on a panel by the other hand; (c) releasing the button slowly when hearing the alarm sound; and (d) reading the values of blood pressure on the panel.
Recently, the wrist type sphygmomanometer with the cuff wrapped around the wrist is invented to solve these problems. Although it is much smaller and easier to use than conventional sphygmomanometer, inflating the air bag on the wrist consumes a lot of electricity, and it is also inaesthetic.
The present invention provides a portable hydraulic sphygmomanometer, comprising (a) a hydraulic belt (30); (b) a pressure sensor (40) operably linked to the hydraulic belt (30) for detecting the pressure of hydraulic belt (30); and (c) a computer device (50) for calculating the pressure. The sphygmomanometer further comprises a power supply (70), a panel (21), a button (22) and a wrist band (10) connected to the main body (20) of sphygmomanometer. The panel comprises a button (21) operably linked to the hydraulic belt (30). The force exerted when pushing the button (21) causes the hydraulic belt (30) to compress the blood vessel. Thus, the blood pressure could be calculated during the process of decompression. Also, the panel (21) shows time, date, and values of pressure.
The sphygmomanometer additionally comprises an alarm device (60), a beat detector (80) and a recorder (90). The beat detector (80) detects the disturbance of blood, and the recorder (90) keeps track of the change of pressure in the hydraulic belt (30).
The present invention significantly saves energy by using a hydraulic belt (30) in substitution for a conventional cuff spring. The power supply (70) set forth could be a solar cell, an alkaline battery, a mercury battery or other kinds of batteries. The hydraulic belt (30) is used to detect the blood pressure of brachial or radial arteries. The hydraulic belt (30) further comprises an impermeable package and a liquid. Also the liquid of the hydraulic belt (30) is non-toxic.
The present invention further provides a method for measuring blood pressure, comprising (a) providing a user with the sphygmomanometer of the present invention and wearing on one hand; (b) pushing a button (22) by the other hand; (c) releasing the button (22) slowly when hearing the alarm sound; and (d) reading the values of blood pressure on the panel (21). The button (22) of the sphygmomanometer is operably connected with the hydraulic belt (30). The alarm sound is emitted by the alarm device (60) when the blood stream is blocked.
The present invention was further detailed in the following examples, which were offered by way of illustration and were not intended to limit the invention in any manners. Standard techniques well known in the art or the techniques specifically described below were utilized.
The axiom of the present invention was the same as the prior art. The present invention used a hydraulic belt (30) in substitution for the conventional cuff spring. The user wore the portable hydraulic sphygmomanometer on one hand as
