Description

Multifunctional capsule capable of sampling and releasing medicine

Technical Field

The invention relates to the field of medical appliances, in particular to a multifunctional capsule capable of sampling and releasing medicine.

Background

The existing sampling capsule technology generally adopts an active technology, and a power module and a circuit module provide power for sampling or detecting positions, wherein the technology for controlling the sampling of the capsule at a specified position mainly comprises two kinds of technologies: 1. taking a picture by adopting a camera arranged in the capsule, transmitting the picture to an external host through a wireless signal, and determining whether to sample at the position after an operator analyzes the picture; 2. the capsule endoscope is guided to move to a designated position by adopting a magnetic control technology through a large magnet outside the body, and then the sampling capsule is controlled to sample by transmitting a command in a wireless transmission way.

The capsules of the two prior art schemes can not realize the two-in-one function of sampling and releasing medicine.

The Chinese patent application 2023104624338 provides a sampling capsule, and the technical scheme of the sampling capsule adopts a control component to send an instruction to pump air to form a vacuum state of a sampling cavity, and a camera arranged in the sampling capsule is convenient for observing the sampling state in real time.

The technical defects of the existing sampling capsules are mainly as follows: 1. the operation is complex, and the operation can be performed only in medical places under the guidance of qualified medical professionals; 2. the function is single, and the sampling can be realized in one capsule only; 3. the cost is high; 4. the volume is limited, the power supply module and the circuit control module occupy the volume of the capsule, the volume of the sampling cavity is limited, and the sampling capacity is insufficient.

Therefore, a novel sampling capsule is necessary to be designed, meanwhile, the medicament can be filled in the sampling cavity in advance, and the medicament is released at the fixed point position, so that the multifunctional capsule design is realized, the operation is simple, the volume is reduced, and the large-scale popularization is convenient.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples, it being understood that the specific examples described herein are only for explaining the present invention and are not intended to limit the present invention.

Referring to fig. 1, which is a cross-sectional view of the overall structure of the multifunctional capsule, the multifunctional capsule of the present invention mainly includes a capsule end cap 10, an inner frame assembly 11 and a capsule bottom shell 12, wherein the inner frame assembly 11 is accommodated in a cavity formed by the capsule end cap 10 and the capsule bottom shell 12.

With further reference to the schematic diagram of the internal components of the multifunctional capsule in fig. 2 and the schematic diagram of the multifunctional capsule in another angle in fig. 3, the internal frame assembly 11 mainly comprises a motor 20, a pipeline 21, a peristaltic pump sheet 22, a sampling tube 23, a power module 24 and a control module 25, wherein the peristaltic pump sheet 22 is a pump sheet formed by six groups of cam structures, at least three small holes are formed in the shell of the multifunctional capsule according to the invention, the peristaltic pump inlet 30, the sampling tube inlet 31 and the PH sensor 32 are respectively arranged, and the motor 20 is a reversible rotating motor.

Referring to the schematic diagrams of the positions of the pump sheets in fig. 4a and the schematic diagrams of the positions of the pump sheets in fig. 4b at another angle, a-f in the figures respectively show the deepest points of the extrusion pipelines 21 which can be reached by 6 groups of pump sheets, when the pump sheets rotate in the direction shown in the figure, the points a-f sequentially pass through the points a-f, wherein the point a indicates the deepest point of the extrusion pipeline of the first pump sheet, the extrusion pipeline of the pump sheets gradually deepens in the rotating process, meanwhile, the extrusion point a of the first pump sheet gradually rises to attract the subsequent digestive juice to be replenished, and the digestive juice in the continuous extrusion pipeline continuously moves from left to right.

The working principle of the invention is as follows: when the multifunctional capsule enters the gastrointestinal tract environment, the PH value sensor 32 detects the PH value of the surrounding environment in real time, and when the PH value reaches the preset PH value, the control module 25 sends a rotation command to the motor 20 so as to drive the peristaltic pump sheet 22 to rotate, and the peristaltic pump sheet 22 sequentially extrudes the pipeline 21 to form negative pressure, so that the digestive juice sampling is completed.

The peristaltic pump 22 is rotated to any position, and one pump or two adjacent pump compression lines are arranged, i.e. in any stopped state, the liquid at two ends of the peristaltic pump 22 is blocked by the peristaltic pump 22.

The rotation direction of the motor 20 can control the extrusion sequence of the peristaltic pump sheets 22, thereby controlling the movement direction of the liquid in the pipeline 21 and achieving the function of sampling or releasing the medicine. With further reference to the sectional view of the sampling state of fig. 5, when the motor 20 rotates to drive the peristaltic pump 22 to rotate, the peristaltic pump 22 sequentially extrudes the pipeline 21 to pump the digestive juice 51 into the capsule, the digestive juice enters the sampling cavity through the pipeline 21, the piston 61 is pushed to move in the sampling cavity to discharge the air 62, and after the piston 61 moves to the limit point 40 of the pump, the digestive juice is stored in the pipeline 21 between the piston 61 of the sampling cavity and the peristaltic pump 22 and the sampling cavity, thereby achieving the purpose of sampling.

The infusion is achieved by the control module 25 sending a reverse rotation command to the motor 20 in the cross-sectional view of the infusion state of fig. 6, and the basic principle is the same as that of the sampling process, and the applicant will not repeat the description here.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
