Description of the Related Art Medical capsules are already known in which the capsule body is used as a cylinder and a piston is moved within the cylinder to introduce digestive juices and the like into the capsule body. Since this type of capsule must start the collection operation at a predetermined position on the main body, the piston is locked at a predetermined position with a thread, and the thread is fused at a desired point by the heat of the filament. However, since the filament is fine and easily sagging, it has been extremely difficult to maintain a constant relationship between the filament and the thread. Therefore, even if a current is applied to the filament under control from outside the body, it may not be possible to reliably melt and cut the thread.

This hollow cylindrical portion is provided with an opening 12 for taking in digestive juices when aligned with the opening 10 of the cylinder portion, and a locking member 13 of 4 is fixed to the right end of the hollow cylindrical portion. Furthermore, a silicone O-ring 14 is installed in a groove on the outer peripheral surface of the movable body 2 in order to improve the sealing performance between the capsule body 1 and the movable body 2. Since the compression coil spring 3 is disposed between the stepped portion of the cylindrical fixed support member 15 integrated with the capsule body 1 and the stepped portion of the movable body 2, the movable body 2 always remains as shown in FIG. biased to the right. However, since the movable body 2 is locked by the thread 4 supported by the fixed support member 15, the state shown in FIG. 1 is maintained until the thread 4 is fused.

Since the reinforcing body 6 is supported with rigidity, the reinforcing body 6 will not sag. Therefore, the reinforcing body 6 prevents the filament 5 from sagging. The filament 5 and the thread 4 are arranged perpendicularly to each other, as is clear from FIGS. 3 and 4, and the thread 4 is in contact with or close to the filament 5.

後に採取した液を検査することになる。 When collecting digestive juices, etc. using a capsule constructed as described above, the subject swallows the capsule shown in Figure 1, and when the capsule reaches the desired position in the body, a transmitter outside the body send electromagnetic waves. Note that whether or not the capsule has arrived at the desired position is determined based on the elapsed time after swallowing or based on X-rays or the like. When electromagnetic waves are sent from outside the body, the receiving coil 20 receives them, turns on the transistor 19, and then turns on the transistor 18 as well. As a result, current is supplied to the filament 5 from the battery 9, the yarn 4 is fused by the heat of the filament 5, the holding of the movable body 2 by the yarn 4 is released, and the movable body 2 is moved to the first position by the force of the coil spring 3. Move to the right in the figure. At this time, the air in the space 26 between the right end of the moving body 2 and the capsule body 1 is gradually exhausted through the opening 11. Therefore, the space 26 acts as an air damper. On the other hand, since the volume of the hollow part 25 of the moving body 2 increases as the moving body 2 moves, the hollow part 25 becomes in a reduced pressure state, that is, a negative pressure state. When the movable body 2 is displaced in this way and the opening 10 of the capsule body 1 and the opening 12 of the movable body 2 match, the hollow part 25 of the movable body 2 is moved to the outside of the capsule body 1, that is, the part where digestive juices etc. are present. Digestive fluid and the like flow into the hollow part 25 under negative pressure. Since the movable body 2 continues to move by the coil spring 3 to the final position shown in FIG. 25 is completely sealed from the outside of the capsule body 1. When the moving body 2 reaches the final position shown in FIG. 2, the detector 7 is pressed at the right end of the moving body 2, and the contact a of the switch 21 shown in FIG. 5 is turned off and the contact b is turned on. As a result, the circuit of the filament 5 is cut off, and the coil 23 and capacitor 22 are coupled in its place, forming a collector-tuned oscillation circuit, and electromagnetic waves are radiated from the body to the outside, and a receiver outside the body receives them. receive,
It can be seen that the collection operation has been completed completely. Once collected, the capsule passes through the intestines and is expelled from the anus after several to tens of hours. Therefore, the liquid collected after being discharged will be tested.
上述から明らかなように、本実施例によれば、

Since the lower end of the coiled filament 5 is fixed by a reinforcing body 6 made of an electrically insulating material with low thermal conductivity, the filament 5 is prevented from sagging in the direction away from the thread 4, and the filament 5 and the thread 4 are contact can be maintained. Therefore, thread 4
The success rate of fusing increases.

The capsule body 1 is provided with conductors 27 to 30, and the movable body 2 is provided with a conductive contact piece 31. While this contact piece 31 connects the conductors 27 and 28, the electric circuit of the filament 5 shown in FIG. 5, and when the movable body 2 moves to the right end of the capsule body 1 and the contact piece 31 connects the conductors 29 and 30, the portion corresponding to the contact point b in FIG. 5 may be connected. Furthermore, the gap between the conductors 27, 28 and 29, 30 in FIG. It's okay.
