The present application does not limit the specific structure of the liquid dispenser 1 as long as it can dispense liquid through the second tube 32, and the liquid dispenser 1 is, for example, a syringe liquid dispenser or a negative pressure pump liquid dispenser.

The gas source 2 is used to control the amount of gas in the first tube 31, and generate corresponding acting force by pumping/inputting gas, in this embodiment, the gas source 2 may be a syringe or an injection pump, and the like, and has a gas outlet (not shown). The first tube 31 is connected to the gas outlet of the gas source 2, so that the gas pumped/output by the gas source 2 enters the first tube 31. The second tube 32 is communicated with the liquid taking end of the liquid taking device 1, so that the taken liquid enters the inside of the liquid taking device 1 through the second tube 32. Meanwhile, the first tube 31 and the second tube 32 may be flexible tubes, which may be made of non-toxic and stable materials, such as silicone rubber, which is biocompatible. In addition, the outer diameters of the first tube 31 and the second tube 32 can be set to 0.5-1.5 mm, so as to ensure that the first tube 31 and the second tube 32 can pass through a long and narrow or continuously bent lumen of the pipeline, and reduce the damage of the tube 3 to the digestive tract.

In a preferred embodiment of the present application, the second end of the second tube 32 is provided with a liquid taking port, and the liquid taking port is close to the end of the capsule endoscope 4 provided with a lens. By reducing the distance between the liquid taking port and the plane where the lens of the capsule endoscope 4 is located, the overlapping degree of the actual liquid taking position of the liquid taking port and the observation position of the capsule endoscope 4 can be improved, and the liquid taking precision of the liquid taking device is improved.

In the embodiment of the present application, the elastic clamping portion 5 may have a deformation tendency of contracting and expanding, the elastic clamping portion 5 has a cavity 51, the cavity 51 is communicated with the air outlet of the air source 2 through the first tube 31, the elastic clamping portion 5 and the first tube 31 may be connected in an adhesive manner or may be integrally formed, and the second end of the first tube 31 is communicated with the elastic clamping portion 5, so that the air pumped/input by the air source 2 exits/enters the cavity 51 through the first tube 31.

Preferably, in the embodiment of the present application, the second end of the first tube 31 is connected to the bottom of the elastic clamping portion 5, and communicates with the cavity 51 through the bottom of the cavity 51. Specifically, the bottom of the cavity 51 is provided with an air hole (not shown), and the second end of the first tube 31 communicates with the cavity 51 through the air hole. The air holes are formed in the bottom of the cavity, so that the elastic clamping part 5 can be uniformly opened during inflation, the capsule endoscope 4 can fall off from the cavity 51, and the capsule endoscope 4 is prevented from falling off due to the fact that the elastic clamping part 5 deforms unevenly.

More preferably, in an embodiment of the present application, the liquid taking device further includes a pressure detecting component (not shown), disposed in the air source or the first pipe 31, for obtaining a pressure value in the first pipe 31, so as to control the air pressure in the first pipe 31 below a preset pressure value, and prevent the air pressure in the first pipe 31 from being low and causing the flexibility of the pipe 3 to be reduced.

The elastic clip section 5 and the capsule endoscope 4 are arranged such that:

as shown in fig. 5, in the clamped state, at least a part of the capsule endoscope 4 is located in the cavity 51, the elastic grip portion 5 is expanded by the urging force of the capsule endoscope 4, at this time, the elastic grip portion 5 has a tendency to return to the deformed state so as to apply a contraction grip force P1 to the capsule endoscope 4, and by this contraction grip force P1, a frictional force F1 is generated at the contact portion of the elastic grip portion 5 and the capsule endoscope 4, and a discharge force F2 generated by the squeezing of the muscle from the digestive tract 6 is received by the capsule endoscope 4, at this time, F1> F2, so that the capsule endoscope 4 is firmly clamped by the elastic grip portion 5 and its movement is restricted by the tube body 3. After the capsule endoscope 4 reaches the target position, the digestive tract 6 can be detected, and meanwhile, the second end liquid of the second tube body 32 is immersed in the liquid of the digestive tract 6, so that liquid can be taken out.

When both testing and fluid extraction are complete, the capsule endoscope 4 may be released, as shown in FIG. 6, to facilitate evacuation of the capsule endoscope 4 or for further examination. At this time, the gas source 2 outputs gas, the gas enters the cavity 51 through the first pipeline, the pressure P2 in the cavity 51 will gradually increase because the elastic clamping part 5 is tightly attached to the capsule endoscope 4, when the pressure P2 reaches a certain degree, the elastic clamping part 5 will be opened, the capsule endoscope 4 is no longer bound by the elastic clamping part 5, the gas will apply a pushing force F3 to the capsule endoscope 4, and then the capsule endoscope 4 can be pulled out from the cavity 51 under the action of the pushing force F3. The tubular body 3 is then removed from the alimentary tract 6.

As shown in fig. 1 and 2, the first tube 31 and the second tube 32 are arranged in parallel, and the middle sections of the first tube 31 and the second tube 32 are fixedly connected to each other, so that the outer diameter of the tube 3 can be reduced to ensure that the tube 3 does not generate an excessively strong foreign body sensation and to prevent the digestive tract 6 from being cut. The second end of the second tube 32 abuts against the outer wall of the elastic clamping portion 5, specifically, (the end portion of) the second end of the second tube 32 abuts against or is attached to the elastic clamping portion 5, and the liquid taking port is disposed at a position other than the connection position. When the capsule endoscope 4 is held by the elastic holding section 5, the second end of the second tube 32 comes into contact with the outer wall of the capsule endoscope 4, and the capsule endoscope 4 takes the second end of the second tube 32 to reach the target position to take out the liquid.

In the embodiment of the present application, in order to reduce the interference of the elastic clamping portion 5 and the tube body 3 on the detection, the elastic clamping portion 5 is connected to one end portion of the capsule endoscope 4 far away from the lens, and the elastic clamping portion 5 at least partially covers the end portion, so that the capsule endoscope can be connected through the elastic force of the elastic clamping portion 5. Alternatively, in order to further increase the clamping force of the elastic clamping part 5 on the capsule endoscope 4, in the embodiment of the present application, the gas source 2 may extract the gas in the first tube 31, so that the gap formed between the first tube 31 and the elastic clamping member 5 and the capsule endoscope 4 forms a negative pressure, thereby enhancing the clamping force of the elastic clamping member 5 and preventing the capsule endoscope 4 from being separated from the elastic clamping member 5 during examination.

In one embodiment, both ends of the capsule endoscope 4 may be configured as a hemispherical structure, the middle section of the capsule endoscope 4 is configured as a cylindrical section 41, and the elastic clamping portion 5 clamps at least a part of the cylindrical section 41. The elastic grip portion 5 accommodates a hemispherical structure of one end of the capsule endoscope 4 and extends to a part of the cylindrical section 41 to increase a contact area of the two, enhancing a clamping effect. In other embodiments of the present application, the middle section of the capsule endoscope 4 may have a shape other than the cylindrical section 41, for example, a truncated cone section, a conical section, an elliptical section, or the like, as long as the elastic clamping member 5 can clamp or release the middle section.

Accordingly, in the above embodiment, the inner wall of the elastic grip portion 5 is a hemispherical inner wall adapted to, for example, a hemispherical structure, and in a state where the capsule endoscope 4 is not gripped by the elastic grip portion 5 (i.e., the hemispherical inner wall is in a natural state), the maximum transverse diameter of the hemispherical inner wall is a first diameter, and the maximum transverse diameter of a portion of the capsule endoscope 4 in contact with the hemispherical inner wall (i.e., a portion of the capsule endoscope 4 in contact with the hemispherical inner wall) is a second diameter, and the first diameter is smaller than the second diameter. So that the capsule endoscope 4 can open the elastic grip 5 and then create a clamping force between the two.

The contact area between the elastic clamping part 5 and the capsule endoscope 4 directly determines the acting force between the two, so that in order to enable the acting force to be moderate in magnitude, the elastic clamping part 5 can be clamped in a clamping state, and the capsule endoscope 4 is convenient to release in a releasing state, the elastic clamping part 5 and the capsule endoscope 4 are configured in the embodiment of the application: in the clamped state, the ratio of the volume of the part of the capsule endoscope 4 located in the cavity 51 to the total volume of the capsule endoscope 4 is 1/5 to 1/2.

In addition, the cross-sectional structure of the elastic clip part 5 along the axial direction of the capsule endoscope 4 is "U" shaped, which is formed by connecting a hemispherical structure and a ring structure. The hemispherical structure abuts the hemispherical inner wall and the annular structure abuts a portion of the cylindrical section 41, thereby clamping the capsule endoscope 4 via the resilient clamping portion 5.

In the embodiment of the present application, the liquid taking device further comprises a control mechanism, a magnet 42 is arranged inside the capsule endoscope 4, and the control mechanism is configured to control the direction and speed of the capsule endoscope 4 through the magnet 42. That is, the posture of the capsule endoscope 4 in the alimentary canal 6 can be adjusted by controlling the magnet 42 and the control structure, so as to adjust the angle and other parameters of the capsule endoscope 4 in the esophagus, thereby facilitating observation.

Based on the structure, an embodiment of the present application further provides a liquid taking method, which is applied to the liquid taking device of any one of the embodiments, and the method includes the following steps:

s001: under normal pressure, the capsule endoscope 4 is clamped through the elastic clamping part 5, at least one part of the capsule endoscope 4 is positioned in the cavity 51 of the elastic clamping part 5, at the moment, the elastic clamping part 5 has the tendency of restoring deformation so as to apply contraction clamping force to the capsule endoscope 4 and further clamp the capsule endoscope 4, and meanwhile, the second end of the second pipe body 32 is abutted against the surface of the capsule endoscope 4;

s002: under the action of the traction force of the tube body 3, the capsule endoscope 4 and the elastic clamping part 5 are placed into a target position, the position is detected, and meanwhile, liquid is taken through the second end of the second tube body 32;

s003: after the liquid is taken out, gas is input into the cavity 51 through the gas source 2 until the elastic clamping part 5 is opened under the action of air pressure, so that the capsule endoscope 4 falls off from the cavity 51, and then the tube body 3 is taken out.

Further, after the capsule endoscope 4 is released, the capsule endoscope 4 can enter the next stage under the thrust of the air flow or the gravity of the capsule endoscope 4, and the capsule endoscope 4 can also be controlled to enter the next stage by an external control mechanism through matching with the magnet 42 in the capsule endoscope 4.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
