The core of the invention is to provide a decomposable pathfinding capsule, which can separate a shell unit under the action of a magnetic field into a plurality of parts with smaller volumes, thus being beneficial to being discharged outside the body.
Another core of the invention is to provide a detection device comprising the resolvable route-exploring capsule.

The decomposable route exploring capsule provided by the specific embodiment comprises an inner core part 1 used for sending signals to the outside and a shell 2 which is wrapped on the periphery of the inner core part 1 and used for simulating the appearance of a capsule endoscope; the shell 2 comprises at least two shell units, wherein at least one of the shell units is a deformation unit which deforms under the action of a magnetic field; in a natural state, the shell units are fixedly connected; under the action of the magnetic field, the deformation unit deforms to separate the fixedly connected shell units.
When the degradable pathfinding capsule provided by the embodiment is used, a user needs to swallow the degradable pathfinding capsule, and the shape of the shell 2 is similar to that of the capsule endoscope, so that the process that the user swallows the degradable pathfinding capsule can be used for simulating the process of swallowing the capsule endoscope, and whether the user is suitable for checking in the mode of the capsule endoscope is judged by judging whether the degradable pathfinding capsule can be discharged out of the body within the specified time; after a certain time, the swallow is generally 30 hours, and of course, the time can also be set according to the specific situation of the user; whether the decomposable exploring capsule exists in the human body or not needs to be detected, if the detection result shows that the decomposable exploring capsule still exists in the human body, the difficulty of discharging the decomposable exploring capsule by a user is proved, at the moment, a magnetic field can be provided near the abdomen of the user, and under the action of the magnetic field, the mutually connected shell units are separated from each other due to the deformation of the deformation unit.
It should be noted that the deformation of the deformation unit mentioned herein may be a material that expands as a whole under the action of a magnetic field, or may be a material that contracts as a whole under the action of a magnetic field, or a material that elongates in a single direction or contracts in a single direction under the action of a magnetic field, which is determined specifically according to actual situations and will not be described herein again.
In addition, the number of the housing units is at least two, and from the perspective of facilitating discharging the inside of the body, the larger the number of the housing units, the smaller the volume of each housing unit after disassembly is, the more beneficial the discharging outside of the body is, and from the perspective of processing cost and assembling process cost, the smaller the number of the housing units is, the more convenient the assembling is, and therefore, the specific number of the housing units needs to be determined according to actual conditions.
Compared with the prior art, the decomposable route exploring capsule provided by the embodiment can be decomposed into the inner core part 1 and each independent shell unit under the action of the magnetic field, and the volume of each independent shell unit and the volume of the inner core part 1 are smaller than the volume of the decomposable route exploring capsule before decomposition, so that the discharge of a user is facilitated, and the decomposable route exploring capsule is prevented from being detained in the body of the user.
On the basis of the above embodiment, it is possible that the deformation unit is the magnetic elongation portion 21 that elongates and deforms under the action of the magnetic field, and at least one of the housing units is the holding portion whose shape remains unchanged under the action of the magnetic field.
The way of assembling the magnetically extendable portion 21 with the holder portion can save material costs by providing the holder portion, since the material costs of the deformation unit are higher than the material costs of the holder portion.
It should be noted that, in the assembling process, one magnetic elongation portion 21 may be connected to one holding portion in a one-to-one correspondence manner, one holding portion may be connected to a plurality of magnetic elongation portions 21, or one magnetic elongation portion 21 may be connected to a plurality of holding portions, it is only required to ensure that the holding portions and the magnetic elongation portions 21 may be fixedly connected together to form the housing 2 without the action of a magnetic field, the shape of the capsule endoscope can be simulated, under the action of the magnetic field, the magnetic elongation portion 21 is elongated and deformed to separate the magnetic elongation portion 21 from the holding portions, so that the housing 2 is decomposed into at least one magnetic elongation portion 21 and at least one holding portion, and the volume of the decomposed housing unit and the core portion 1 is smaller than the volume of the decomposed route exploring capsule before decomposition, thereby facilitating the discharge of a user.
Further, the deformation unit may be a magnetostrictive portion 22 that contracts and deforms under the action of a magnetic field, and at least one of the housing units may be a holding portion whose shape remains unchanged under the action of a magnetic field.
Compared with the above embodiment, the arrangement of the magnetic contraction part 22 is more beneficial to the discharge of a user because the magnetic contraction part 22 contracts and shortens compared with the case that the magnetic extension part 21 deforms under the action of a magnetic field, and under the condition that the volume of the initially decomposable exploring capsule is consistent and the division of the shell units is consistent, the volume of the magnetic contraction part 22 after decomposition is smaller than the volume of the magnetic extension part 21 after decomposition.
In the assembling process, one magnetostrictive part 22 can be connected with one holding part in a one-to-one correspondence manner, one holding part can correspond to a plurality of magnetostrictive parts 22, or one magnetostrictive part 22 corresponds to a plurality of holding parts, and only under the condition that no magnetic field acts, the holding part and the magnetostrictive part 22 can be fixedly connected together to form the shell 2, so that the shape of the capsule endoscope can be simulated; under the action of the magnetic field, the magnetic contraction part 22 is shortened and deformed, so that the magnetic contraction part 22 is separated from the holding part, the shell 2 is decomposed into at least one magnetic contraction part 22 and at least one holding part, and the shell unit and the core part 1 after decomposition are smaller than the decomposable exploring capsule before decomposition, thereby being beneficial to the discharge of a user.

Compared with the above embodiment, the case unit is provided with both the magnetic elongation portion 21 and the magnetic contraction portion 22, so that the case 2 has both an elongated portion and a shortened portion under the action of the magnetic field, the relative deformation amount of the whole case is increased, the case 2 can be decomposed favorably, and the situation that the decomposition is insufficient due to insufficient deformation amount is avoided.
It should be noted that, in the assembly process, the housing unit may only include the magnetostrictive extensions 21 and the magnetostrictive portions 22, and the magnetostrictive extensions 21 and the magnetostrictive portions 22 may be connected in a one-to-one correspondence, or a plurality of magnetostrictive extensions 21 are all connected to one magnetostrictive portion 22, or a plurality of magnetostrictive portions 22 are all connected to one magnetostrictive portion 21, which is determined according to actual conditions.
The housing unit may further include at least one magnetic elongation portion 21, at least one magnetic contraction portion 22, and at least one holding portion, the outer dimension of which is kept constant under the action of the magnetic field, and the holding portion is engaged with or disengaged from the magnetic elongation portion 21 or the magnetic contraction portion 22, so as to ensure that the housing 2 can be successfully decomposed into a plurality of housing units under the action of the magnetic field.

In order to enable the clamping portion 24 and the clamping groove 23 to be fixedly connected in a natural state and avoid accidental separation under the action of external force, the clamping groove 23 can comprise a first groove and a second groove which are arranged on the inner side of the shell unit, and the first groove and the second groove are symmetrically arranged along the length direction of the shell unit.
As shown in fig. 6, the first groove and the second groove are arranged along the length direction of the magnetic elongation portion 21, and under the action of the magnetic field, the magnetic elongation portion 21 is elongated and deformed, so that the distance between the first groove and the second groove is increased, and the clamping portion 24 is disengaged from the clamping groove 23, thereby realizing the decomposition of the housing 2.
On the basis of the above embodiment, a fixing groove 25 for fixing the core portion 1 may be provided on the inner side of at least one housing unit, and the fixing groove 25 may be provided to fix the core portion 1 relative to the housing 2 before the housing 2 is disassembled, so as to avoid the core portion 1 moving relative to the housing 2 and increasing the discomfort of the user.

It should be noted that the first and second recesses mentioned in the present application are only for limiting the position difference and are not in sequence.
Further, the magnetostrictive extension 21 and the magnetostrictive contraction 22 mentioned in the present document may be an iron-gallium alloy Fe83Ga17, and the iron-gallium alloy Fe83Ga17 may exhibit elongation or contraction under the action of an external magnetic field depending on the processing technique or the magnetizing direction.
On the basis of the above embodiment, the resolvable route exploring capsule further comprises at least one acceleration sensor and at least one pressure sensor, wherein the acceleration sensor is arranged in the inner core part 1, and the pressure sensor is arranged outside the shell 2.
In use, the external device may be provided with a first data receiver for receiving data measured by the acceleration sensor, a second data receiver for receiving data measured by the pressure sensor, and a processor for processing data measured by the first data receiver and the second data receiver. The acceleration sensor can transmit the detected data to the first data receiver, and the processor judges the shape and the patency degree of the cavity according to the acceleration information transmitted by the acceleration sensor. The external device is an external detection device which is used together with the decomposable pathfinding capsule and is used for detecting the condition of the decomposable pathfinding capsule in the cavity and the channel.

Preferably, at least two acceleration sensors can be arranged, and the acceleration sensors are respectively arranged at different positions of the decomposable route exploring capsule so as to obtain the parameters of the decomposable route exploring capsule in a rotating state.
In the detection process, the acceleration conditions of different parts of the decomposable route exploring capsule can be obtained, and comprehensive judgment is carried out by combining the body position of a human body, for example, after the human body swallows the decomposable route exploring capsule, when the human body is in a standing posture, the decomposable route exploring capsule is generally in a vertical state, when the data measured by the acceleration sensor is not zero and the decomposable route exploring capsule can be proved to be in a motion state, the smoothness in the section of vertical cavity or vertical channel is proved to be good; when the human body is in a lying posture, the decomposable pathfinding capsule is generally in a transverse state, and when the data measured by the acceleration sensor is not zero and the decomposable pathfinding capsule can be proved to be in a motion state, the patency degree in the transverse cavity or channel of the section is proved to be good.
The processor is used for processing the data received by the first data receiver, for example, the speed and direction of the motion of the resolvable exploring capsule can be calculated according to the data measured by the acceleration sensor.
Preferably, at least three pressure sensors can be arranged, wherein two pressure sensors are respectively arranged at two ends of the length direction of the decomposable route exploring capsule, and at least one pressure sensor is arranged at the peripheral side surface of the decomposable route exploring capsule.
In the using process, when the number of the pressure sensors is large, the pressure data received by the second data receiver can be converted into a pressure cloud picture through the processor, so that the pressure distribution on different parts of the decomposable pathfinding capsule can be conveniently observed; in addition, the processor can be combined with the data measured by the pressure sensor and the acceleration sensor to judge the specific blocking position of the cavity or the channel, for example, when a human body is in a standing state, the data measured by the pressure sensor can judge which specific part of the decomposable route exploring capsule is extruded, and the approximate position of the decomposable route exploring capsule can be measured according to the data measured by the acceleration sensor and the signal emitted by the signal emitting part, so that the specific blocking position of the cavity or the channel can be roughly determined.
