Description

Изобретение относитс к медицине, а именно к устройствам дл измерени физиологических показателей.The invention relates to medicine, specifically to devices for measuring physiological parameters.

Известна радиокапсула дл измерени активности ферментов, содержаща источник питани , радиопередатчик, корпус и датчик кислотности, не обладает необходимой надежностью .The known radio capsule for measuring the activity of enzymes containing a power source, a radio transmitter, a housing and an acidity sensor does not have the required reliability.

Целью изобретени вл етс повышение надежности радиокапсулы.The aim of the invention is to increase the reliability of the radio capsule.

Достигаетс это тем, что радиопередатчик выполнен в виде туннельного диода, а источник питани - биогальванический элемент- в виде -корпуса и датчика кислотности.This is achieved by the fact that the radio transmitter is made in the form of a tunnel diode, and the power source is a bio-galvanic element in the form of an enclosure and an acidity sensor.

На чертеже изображена предлагаема радиокапсула и разрез по А-А.The drawing shows the proposed radiocapsule and a cut along the AA.

Радиокапсула содержит источник питани в виде биогальванического элемента, состо щего из алюминиевой пластины 1 и пластины 2 из хлористого серебра, разделенных изол ционной резиной 3, электролитом которого служат желудочный сок и жидка фаза пищи , вл ющегос одновременно корпусом иThe radio capsule contains a food source in the form of a bio-galvanic element consisting of an aluminum plate 1 and a plate 2 of silver chloride, separated by insulating rubber 3, the electrolyte of which is the gastric juice and the liquid phase of the food, which is both the body and

датчиком кислотности; радиопередатчик 4, выполненный в виде туннельного диода.acidity sensor; radio transmitter 4, made in the form of a tunnel diode.

Раднокапсула работает следующим образом .Radnocapsule works as follows.

В зависимости от кислотности желудочного сока измен етс внутреннее сопротивление биогальванического элемента и, следовательно , емкость перехода туннельного диода, вли ющего в свою очередь на частоту колебательного контура радиопередатчика, антенной которого служит катущ-ка индуктивности 5 с ферритовым сердечником.Depending on the acidity of the gastric juice, the internal resistance of the biogalvanic element changes and, consequently, the junction capacitance of the tunnel diode, which in turn affects the frequency of the oscillating circuit of the radio transmitter, the antenna of which serves as an inductance cable 5 with a ferrite core.

Предмет изобретени Subject invention

Радиокапсула дл исследовани желудочно-кищечного тракта, содержаща источник питани , радиопередатчик, корпус и датчик кислотности, отличающа с тем, что, с целью повыщени надежности, радиопередатчик выполнен в виде туннельного диода, а источник питани - биогальванический элемент - в виде корпуса и датчика кислотности .A radio capsule for researching the gastrointestinal tract, containing a power source, a radio transmitter, a housing, and an acidity sensor, characterized in that, in order to increase reliability, the radio transmitter is made in the form of a tunnel diode, and the power source is a bio-galvanic cell - in the form of a housing and an acidity sensor .
