DE2703448A1 - Self operated blood pressure measuring device - is secured under arm and operated with pumping action for indication on dial - Google Patents

Abstract

The device enables a person to measure his blood pressure unaided. It has a member which is fitted under the user's arm, and above which is a movable assembly (c, d) housing a spring (2). The two portions of the movable assembly are operated against the force of the spring with a pumping action. The assembly is retained by a crank or gripping member (f) at the side. The diastolic and systolic pressures are then indicated by a pointer moving over a scale. An alternative design does not use an indicator.

Description

Self-blood pressure monitor for everyone

High blood pressure (hypertension) is a very common disease and has devastating consequences if it is not recognized or not recognized early.

This device was invented so that everyone could get it and themselves can measure the blood pressure more often even at home, just like the one with a donor thermometer because the device has a very simple structure, easy to use and very inexpensive to manufacture is. To measure blood pressure you don't fry a cuff or a utethoscope.

The device consists of a solid. and a moving part. Of the fixed part consists of an elongated plate a, which is connected to the plate b is (Fig.1): The moving part consists of the also elongated plate c, which is connected with b, and the elongated plate d, which is connected with c by a rail connected (Fig. 1). The spring e is attached between the plates c and d, which has a function similar to that of the Bourdon tube in a pressure gauge. The plate c can be moved against a by the crank or the rotary handle f. The plates c and d can also be moved relative to one another. The latte d is with an egg connected (iibb. 1), of the blood pressure values shows on the scale. The fixed point of the pointer is a stick o; , the far left on the ilatte c that is attached to the leverage of the pointer and dadurcll the deflections very much are great. To measure blood pressure, the forearm is used in the distal area and with the Palmar side up into the device so that it is from the plates a and is included. Then the crank f is turned and so the plate d @@ egen the forearm pressed until the pointer shows pulse-synchronous movements. The value shown is the diastolic pressure. If you turn f @ ort a little further, the deflections slowly cease. The value now shown on the scale is the systolic pressure.

Wieser's process can also be carried out in reverse.

A red area on the scale may indicate the pathological blood pressure demonstrate.

Claims self-blood pressure meter for everyone 1. Construction, function and use of the device, characterized in that the forearm in the distal Area and with the palmar side up between a solid (e. Fig. 1) and a manageable part (d c) of the device through the crank or the rotary handle f and with the help of the spring e is compressed and released again and the Transferring pressure values to a zei @ or, amplifying them by means of a gag effect and at the beginning and at the end of the pulsations of the pointer the corresponding values the diastolic and systolic blood pressure can be measured on a scale . The device is also characterized in that it is very easy to build and can be produced cheaply; it is used to measure blood pressure and is also characterized by the fact that you do not need any special knowledge, another lianschette or a titletloscope. 2. To generate pressure, the device described can be used instead also use a rubber hose attached under c and through a ground Blower is on-inflated; then d and f (Fig.1) would appear and instead of a Bourdon tube must be attached to the pointer.
