Description

Wrist type digital blood pressure monitor equipped with touch panel

The present invention is to install a touch panel on the liquid crystal display panel instead of separately installing a control button operated by the user for blood pressure measurement on the wrist-type digital sphygmomanometer, without increasing the area and volume of the case forming the exterior liquid crystal for the case The present invention relates to a wrist-type digital sphygmomanometer equipped with a touch panel that can increase the installation area of the display panel, thereby bringing an extension of the visible area of the user, and which is easier to operate than a digital sphygmomanometer equipped with control buttons.

In general, there are two types of blood pressure monitors, traditional mercury or mercury-type analog sphygmomanometers, and digital sphygmomanometers, which have recently come into the spotlight. The former can measure blood pressure by using a stethoscope to measure the height of the mercury or the scale indicated by the needle. While the cuff can inflate air with a rubber pump to measure blood pressure very accurately, the latter can automatically inflate air to the cuff using a motor pump and the user's blood pressure can be displayed on the screen numerically. Because it appears, it is very easy to read, and since it is not necessary to use a stethoscope, the hearing impaired person can easily measure blood pressure, and most of all, it is very popular because it is very easy to measure blood pressure alone.

Briefly looking at the prior art of the digital sphygmomanometer and its operation principle is provided with an air pump to supply air by the driving of the motor inside the case and the air generated by the air pump is supplied to the cuff connected to the pipeline After the pressure of the cuff reaches a certain level, the pressure reducing valve installed in the conduit is operated and the air supplied to the cuff is gradually discharged to reduce the pressure. After the blood pressure measurement, the solenoid valve connected to the conduit is operated. The remaining air remaining in the cuff is discharged to prepare for the next measurement. As described above, the pipeline, the pressure reducing valve, and the solenoid valve are operated to inject and discharge the air into the cuff. It is executed by pressing the start button or the mode setting button. These buttons are connected to a control device such as a printed circuit board (PCB) inside to control the operation of the valve, etc., so that the start and end of blood pressure measurement can be easily operated with a button. .

In addition, the cuff is connected to the pressure sensing device inside the blood pressure monitor so that some of the air injected into the cuff enters the pressure sensing device. In the pressure sensing device, air introduced through the cuff is gradually discharged by the operation of the pressure reducing valve. While detecting the pressure of the air when the systolic blood pressure is detected and the pressure of the air when the diastolic blood pressure is detected, and serves to deliver the pressure signal of the air to the control device, the control device is a pressure sensing device After converting the pressure signal transmitted from the blood pressure signal to the liquid crystal display panel to display the systolic and diastolic blood pressure to the user to complete the blood pressure measurement.

On the other hand, the upper part of the blood pressure monitor is provided with a control button for controlling the start and mode setting, etc., with the liquid crystal display panel, because the wrist-type digital blood pressure monitor is usually small because the size of the liquid crystal display panel is small, The user is inconvenient to see the instrument panel, and due to the space occupied by the control button, there is a limit to expand the visible area by increasing the size of the liquid crystal panel.

Of course, in order to expand the size of the liquid crystal panel, the size of the blood pressure monitor itself may be designed to be larger, but this is far from the recent trend to realize miniaturization, light weight, and high integration of electronic products, and the blood pressure monitor is worn on a wrist. In order to measure blood pressure, the size of the blood pressure monitor itself may be increased indefinitely.

Accordingly, technical proposals for realizing the expansion of the liquid crystal panel while having the same size without departing from the above technical limitations are emerging.

The present invention was conceived in view of the above circumstances, and by mounting a touch panel on the liquid crystal panel instead of a separate control button and allowing the touch panel to be connected to a control device inside the blood pressure monitor, the user directly inputs a signal on the screen. By increasing the size of the liquid crystal panel while maintaining the size of the blood pressure monitor itself, it is possible to provide an extension of the visible area and to provide a wrist-type digital sphygmomanometer equipped with a touch panel that is easier to control the operation. There is a purpose of the present invention.
