Description

Technical Field

[0001] This utility model relates to the field of electrocardiograph technology, specifically to a lead suction bulb anti-dislodgement structure for an electrocardiograph. Background Technology

[0002] The lead suction bulb of an electrocardiograph is an important component used in electrocardiogram (ECG) examinations to contact the human skin and obtain electrical signals.

[0003] Currently, in the use of lead suction bulbs in electrocardiographs, a metal cover is placed on the skin to be tested. By pressing the lead suction bulb, a negative pressure is created between the metal cover and the skin, and then the electrical signal is acquired. However, the lead suction bulbs of electrocardiographs are prone to falling off, lacking a limiting and anti-fall-off structure. When multiple lead suction bulbs are used repeatedly, the falling off phenomenon can easily cause inconvenience to medical staff and the tested patients. Therefore, this problem needs to be addressed and improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a lead suction bulb anti-dislodgement structure for an electrocardiograph. The structure includes a limiting sleeve, which is a hollow cylindrical structure made of transparent material. The limiting sleeve and the lead wire are interference-fitted, which restricts the displacement of the connecting sleeve on the lead wire. The structure also includes a protrusion and a limiting seat, further restricting the rotational freedom of the connecting sleeve on the lead wire, thereby improving the reliability of the lead suction bulb during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lead suction bulb anti-dislodgement structure for an electrocardiograph includes a cable, a conductor on the side of the cable, a connecting sleeve on the conductor, a connecting ring on the side of the connecting sleeve connecting to the lower part of the lead suction bulb, a metal cover at the bottom of the lead suction bulb, and a limiting sleeve on the side of the connecting sleeve away from the cable and on the conductor.

[0007] As a further improvement to the above solution, the limiting sleeve is a hollow cylindrical structure made of transparent material, and the limiting sleeve and the wire are interference fit.

[0008] As a further improvement to the above solution, multiple anti-slip textures are provided on the outer surface of the middle of the guide suction ball.

[0009] As a further improvement to the above solution, the connecting sleeve is provided with multiple protrusions at one end near the cable, and the protrusions are matched with the limiting seats provided on the side of the cable.

[0010] As a further improvement to the above solution, the protrusion has a rectangular block structure and is arranged in a circumferential array outside the connecting sleeve.

[0011] As a further improvement to the above solution, a connecting plate is provided on the side of the connecting sleeve, and the connecting plate is internally equipped with a connecting piece on the side of the connecting ring. The connecting piece and the connecting plate are connected by a nut, a spring washer and a double-ended bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This application includes a limiting sleeve, which is a hollow cylindrical structure made of transparent material. The limiting sleeve and the wire are interference-fitted, which can limit the displacement of the connecting sleeve on the wire. It is provided with a protrusion and a limiting seat, which can further limit the rotational freedom of the connecting sleeve on the wire, thereby improving the reliability of the connecting suction ball when in use.
