Problems solved by technology

[0002] Currently, there are many system designs for gut fluid sampling or drug delivery; however, existing gut sample collection, drug delivery devices for sample collection, or drug delivery can only be performed in a single action
For liquid sampling, if a single sampling fails, such as collecting air, the device will fail and a new device will need to be used again
[0003] Moreover, the existing digestive tract sample collection device passively samples, and its sampling rate and sampling volume are difficult to estimate: if the sampling time is too long, it may cause a large change in the area where the sampling takes place, and the positioning accuracy is low; if the sampling time is too short, it may cause Insufficient sample size

Abstract

The invention provides a sampling / drug delivery capsule, comprising a shell, a sampling / drug delivery assembly and a control module. The shell comprises a first shell body and a second shell body, andat least part of the first shell body comprises a supporting body with a plurality of first open holes, and liquid-proof gas-permeable membranes, at the first open holes, in the supporting body; thesampling / drug delivery assembly comprises a storage cavity, a temporary storage cavity located in the shell, a first unidirectional element enabling the outside of the sampling / drug delivery capsule to communicate with the temporary storage cavity, a second unidirectional element enabling the temporary storage cavity to communicate with the storage cavity, and a pump changing the pressure in the temporary storage cavity, wherein at least part of the storage cavity is formed by the liquid-proof gas-permeable membranes in an enclosed mode, and the communicating directions of the first unidirectional element and the second unidirectional element are the same; and the control module comprises a microprocessor in communication connection with the pump. According to the sampling / drug delivery capsule, through cooperation of the first unidirectional element, the second unidirectional element, the liquid-proof gas-permeable membranes and the pump, multi-time sample introduction and drug delivery can be realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sampling / drug administration capsule capable of sampling and administering medicine multiple times. Background technique [0002] Currently, there are many system designs for digestive tract fluid sampling or drug delivery; however, existing digestive tract sample collection, sample collection or drug delivery of drug delivery devices can only perform a single action. For liquid sampling, if a single sampling fails, such as collecting air, the device will fail, and a new device needs to be used again. [0003] Moreover, the existing digestive tract sample collection device passively samples, and its sampling rate and sampling volume are difficult to estimate: if the sampling time is too long, it may cause a large change in the area where the sampling takes place, and the positioning accuracy is low; if the sampling time is too short, it may cause Insufficient sample si...
