Abstract
The present invention pertains to a swallowable electrochemical sensor, which is characterized in that its housing has electrolyte inlets, through which an aqueous electrolyte, for example, gastric acid, can enter from the area surrounding the sensor into the interior and act as an electrolyte there.
Claims15
A swallowable electrochemical sensor for detecting gases in the intestinal tract of a person, the electrochemical sensor comprising:
- a housing;
- at least one working electrode;
- a counterelectrode;
- a gas-permeable membrane;
- and
- a hydrophilic sealant,
- wherein the housing has an interior space, in which the working electrode and the counterelectrode are arranged,
- wherein the housing has at least one gas inlet,
- wherein the at least one gas inlet is closed with the gas-permeable membrane,
- wherein the housing has at least one electrolyte inlet, and
- wherein the at least one electrolyte inlet is filled with the hydrophilic sealant.
A process for providing a swallowable electrochemical sensor, the electrochemical sensor comprising:
- a housing;
- a working electrode;
- a counterelectrode;
- a gas-permeable membrane;
- and a hydrophilic sealant, wherein the housing comprises an interior space, in which the working electrode and the counterelectrode are arranged, and the housing comprises a gas inlet closed with the gas-permeable membrane, and the housing comprises an electrolyte inlet filled with the hydrophilic sealant, the process comprising the steps of:
- a. providing the electrochemical sensor as an unfilled electrochemical sensor;
- b. providing an electrolyte solution;
- c. bathing the unfilled electrochemical sensor in the electrolyte solution;
- d. providing the electrochemical sensor as prefilled electrochemical sensor.
A kit for detecting intestinal gases, the kit comprising:
- an electrochemical sensor, the electrochemical sensor comprising a working electrode;
- a counterelectrode;
- a gas-permeable membrane;
- a hydrophilic sealant and a housing, the housing comprising an interior space, in which the working electrode and the counterelectrode are arranged, a gas inlet closed with the gas-permeable membrane, and an electrolyte inlet filled with the hydrophilic sealant, wherein the electrochemical sensor is an unfilled electrochemical sensor;
- and
- an electrolyte preparation.
