Problems solved by technology
However, the pH sensors currently used in the gastrointestinal tract mainly include glass electrodes, antimony electrodes, and hydrogen ion sensitive grids. Among them, glass electrodes are bulky and difficult to integrate in capsules; antimony electrodes have limited life and are easily corroded; hydrogen ion sensitive grids Poor stability and short service life

The invention provides a gastrointestinal tract positioning switch. The gastrointestinal tract positioning switch comprises a substrate, a first electrode, a second electrode, conductive devices and positioning film, wherein the first electrode and the second electrode are fixedly arranged on the substrate at an interval, the first electrode and the second electrode are electrically connected withthe conductive devices respectively, the positioning film covers the first electrode and the second electrode, the first electrode and the second electrode are both inert electrodes, and the positioning film is dissolved or / and degraded to expose the first electrode and the second electrode in the stomach or intestinal tract. The invention also provides a manufacturing method of the gastrointestinal tract positioning switch and a digestive tract site-specific delivery capsule. The gastrointestinal tract positioning switch integrates two functions of positioning and triggering, and does not require external large instruments for gastrointestinal tract positioning, so that SSDC becomes simple in operation and use, and independent medication of a patient is achieved; on the other hand, not only is space in the capsule saved, but also sufficient space is provided for delivery and sampling of the capsule, and the cost of SSDC is also reduced.
Description
technical field [0001] The invention relates to the technical field of gastrointestinal tract positioning, in particular to a gastrointestinal tract positioning switch, a manufacturing method thereof, and a digestive tract fixed-point drug release capsule. Background technique [0002] At present, most chronic diseases of the gastrointestinal tract require oral medicines for long-term treatment, but because the medicines stay in the body for a short time and are greatly affected by gastric acid, the medicines that reach the lesion will be reduced or even unable to reach the lesion, thereby reducing the efficacy of the medicine . In addition, statistics show that about 40% of candidate new drugs are eliminated not because of their poor curative effect on the human body, but because of poor experimental methods in the early development process of new drugs, which cannot accurately obtain the absorption characteristics of candidate drugs in different regions of the digestive tr...
