Description

Предметом изобретени   вл етс  портативный электромагнитный баллистокардиограф дл  исследовани  продольных пульсовых движений тела человека, св занных с перемещением крови при сокращени х сердца.The subject of the invention is a portable electromagnetic ballistocardiograph for the study of longitudinal pulse movements of the human body associated with the movement of blood during contractions of the heart.

Описываемый аппарат  вл етс  приставкой к электрокардиографу и служит подставкой под ноги лежащего на спине больного (фиг. 1). Действие устройства основано на принципе регистрации баллистокардиограмм совмещением особенностей двух известных способов-пр мого и косвенного.The described device is an attachment to an electrocardiograph and serves as a support for the patient lying on his back (Fig. 1). The operation of the device is based on the principle of registration of ballistocardiograms by combining the features of two known methods, direct and indirect.

В отличие от громоздких баллистокардиографических столов, состо щих из нескольких частей, и аппаратов дл  пр мого и косвенного методов , предлагаемый аппарат (приставка к электрокардиографу) представл ет собой единую малогабаритную конструкцию, удобную дл  применени  в щирокой медицинской практике.Unlike bulky ballistocardiographic tables, consisting of several parts, and devices for direct and indirect methods, the proposed device (an attachment to an electrocardiograph) is a single compact design suitable for use in a wide medical practice.

Портативный электромагнитный баллистокардиограф (фиг. 2) состоит из двух площадок / п 4, жестко соединенных между собой четырьм  плоскими стальными пружинами 3. К верхней площадке / при помощи специальной панели 5 прикреплен подковообразный магнит 6, с нижней площадкой 4 жестко скреплена индукционна  катущка 7, концы которой с и б подключаютс  на вход электрокардиографа Соединительными элементами дл  стальных пружин и катущки  вл ютс  металлические уголки 2 и S.The portable electromagnetic ballistocardiograph (Fig. 2) consists of two pads / p 4 rigidly interconnected by four flat steel springs 3. A horseshoe-shaped magnet 6 is attached to the upper pad / using a special panel 5, an induction coil 7 is rigidly fastened to the bottom pad 4, the ends of which with and b are connected to the input of the electrocardiograph. The connecting elements for the steel springs and the rollers are metal corners 2 and S.

Пульсовые смещени  передаютс  верхней площадке аппарата, вследствие чего она смещаетс  относительно нижней в направлении продольной оси тела и перпендикул рно к плоскости стальных пружин. При смещении магнита, соединенного с верхней площадкой, магнитные силовые линии пересекают витки катущки и в ней возникает электрический ток, пропорциональный скорости смещени  магнита, а следовательно, скорости смещени  верхней площадки и тела. Регистрацией этого тока с помощью электрокардиографа заппсываетс  баллистокардиограмма скорости .Pulse displacements are transmitted to the upper platform of the apparatus, as a result of which it is displaced relative to the lower one in the direction of the longitudinal axis of the body and perpendicular to the plane of the steel springs. When the magnet connected to the upper platform is displaced, the magnetic lines of force intersect the turns of the coil and an electric current occurs in it proportional to the speed of displacement of the magnet and, consequently, the speed of displacement of the upper platform and body. By recording this current with an electrocardiograph, a ballistocardiogram of speed is recorded.

Предмет изобретени Subject invention

Портативный электромагнитный баллистскардиограф (приставка к электрокардиографу), снабженный индукционной катушкой и магнитом, отличающийс  тем, что, с целью воспри ти  только продольных смещений по оси тела человека и нечувствительности к толчкам и смещени м в боковом и поперечном направлени х, а также упрощени  самой конструкции, он оформлен как подставка дл  ног,  вл юща с  датчиком к электрокардиографу, и выполнен из двух небольших площадок, соединенных между собой четырьм  плоскими стальными пружинами, к верхней площадке крепитс  магнит, а к нижней-индукционна  катущка.A portable electromagnetic ballistic cardiograph (attachment to an electrocardiograph) equipped with an induction coil and a magnet, characterized in that, in order to perceive only longitudinal displacements along the axis of the human body and insensitivity to shocks and displacements in the lateral and transverse directions, as well as to simplify the design itself It is designed as a footrest, which is a sensor for an electrocardiograph, and is made of two small platforms, interconnected by four flat steel springs, to the upper platform of the support with a magnet, and the lower-induction katuschka.
