Embodiment 1

[0029] This embodiment is basically as figure 1 Shown: a power supply structure, including a power supply battery 6, a magnet 4, and a conductive connecting piece 5 formed with an accommodating space, the conductive connecting piece 5 is in the shape of a "C", and the magnet 4 is arranged in the accommodating space of the conductive connecting piece 5 . One pole of the power supply battery 6 is welded and fixed to the conductive connecting piece 5, and the other pole of the power supply battery 6 is electrically connected to the load. The horizontal straight portion of the upper end of the sheet 5 is electrically connected to the load. The power supply battery 6 , the conductive connecting piece 5 and the load form a circuit loop, and the power supply battery 6 supplies power to the load through the conductive connecting piece 5 . The load of this embodiment includes a PCB board, the PCB board includes the upper part 11 of the PCB board and the lower part 12 of the PCB board...

Embodiment 2

[0033] This embodiment is basically as figure 2 As shown: a capsule endoscope, including a capsule-shaped casing 9, the power supply structure of Embodiment 1 is arranged in the casing 9, a gap 91 is provided between the casing 9 and the power supply structure, and a gap 91 is provided in the gap 91. There is an antenna 8 electrically connected to the PCB board. The antenna 8 is made of a steel sheet. In this embodiment, copper sheet is preferred. The antenna 8 can be bent into a ring or a part of the ring. In this embodiment, the bent antenna 8 is set around the battery. Of course, the antenna 8 can also surround the power supply structure. Other positions in the length direction are set; the height of the antenna 8 is 4 mm to 8 mm, preferably 6 mm.

Abstract

The invention relates to the technical field of medical devices, and discloses a capsule endoscope, which includes a capsule-shaped casing and a power supply structure installed in the casing; the power supply structure includes a power supply battery, a magnet, and a conductive connection forming an accommodation space The magnet is set in the accommodation space of the conductive connecting piece, the two poles of the power supply battery are electrically connected with the conductive connecting piece and the load respectively, and the end of the conductive connecting piece far away from the power supply battery is also electrically connected with the load to form a circuit loop; the power supply structure and There is a gap between the shells, and an antenna electrically connected to the PCB board is arranged in the gap, and the antenna is arranged around the power supply structure. In the present invention, the magnet is arranged in the accommodating space of the conductive connecting piece, so that the conductive connecting piece straddles the magnet and is directly electrically connected to the load, which can effectively solve the power supply problem of the endoscope when the capsule endoscope in the prior art adopts the spring contact power supply mode. Bad contact problem. The invention can effectively utilize the internal space of the endoscope, making the endoscope more compact and delicate.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a capsule endoscope. Background technique [0002] The commonly used power supply methods for capsule endoscopes are spring contacts. This method can meet the power supply demand when all the internal parts of the capsule endoscope are not moving. However, a magnet is provided inside the gastric capsule endoscope (hereinafter referred to as the endoscope), and the power supply battery in the endoscope is conducted to the spring through the magnet to supply power to the load. [0003] When examining the human stomach with an endoscope, the magnetic field of the magnet outside the endoscope pulls the endoscope to move in the human body. When the endoscope is pulled to move, the magnet inside the endoscope has the risk of moving. Once the endoscope The activity of the magnet inside may cause the spring to be in poor contact with the load. Poor contact will cause the e...
