Alimentary tract drug release remote controlled capsule system

Abstract

The invention relates to an enteron remote-control drug release capsule system. Wherein, it comprises external remote controller and electric capsule; the electric capsule comprises frame, remote-control circuit, spring, piston, positioning mark resource, and drug release channel; the remote-control circuit has electromagnetic couple unit, without energy storage unit; the couple unit comprises couple antenna, resonance circuit; the external remote controller comprises a high-frequency electromagnetic field generator; the couple antenna couples the electromagnetic energy generated by said high-frequency electromagnetic field generator, to obtain the resonance voltage via the resonance circuit; said resonance voltage is generated by micro heating resistance and other circuits of electric capsule. The invention has small volume and high safety.

Description

Technical field: [0001] The invention relates to a capsule system for remote drug release in the digestive tract, which is used for remote release of substances, such as medicine, food, markers, etc., in the digestive tract of animals or human bodies. Background technique: [0002] The remote drug release capsule system is a drug release system based on micro-mechanical electronic technology. It can control the release time and release position of drugs in the digestive tract through external remote control. It has good application value in clinical treatment and research on drug absorption in the digestive tract. . In Chinese patent CN200410040809.3, a fixed-point release device for digestive tract drugs is disclosed, which includes an external remote control mechanism and an electronic capsule that can be swallowed. The release channel mechanism and the positioning mark source are characterized in that the cavity between the piston, the inner wall of the shell and the dru...

Problems solved by technology

[0003] There are following two disadvantages in the above-mentioned invention: one is that the energy source of the electronic capsule adopts a button battery, and the battery has a chronic power consumption phenomenon. Therefore, after the capsule is encapsulated, the power consumption of the battery will cause a decrease in reliability. Composition, once the capsule leaks, it will cause potential harm to the human body. In addition, due to technical limitations, the button battery has a large volume and occupies a large space, resulting in a large capsule volume that is difficult to swallow, or resulting in a bulky medicine storage compartment. Smaller, difficult to pack enough medicine

Another disadvantage is that after triggering the capsule to release the drug, whether the drug is released successfully or not, there is a lack of verification information, and in vitro operators cannot know whether the drug release is successfully triggered
