Description

Probe and breast machine

Technical field

The present application relates to a medical detection device, in particular to a probe and a mammary gland machine.

Background technique

Breast machine is a device for breast examination and diagnosis of breast lesions.

A probe box is installed on the cantilever of the mammary gland, and a probe head and other devices are installed in the probe box. The lower end (detection end) of the probe box has an opening, and the probe head is exposed through the opening at the lower end of the probe box. During detection, the probe head in the probe box will be moved close to or in contact with the human body. In order to protect the human body and the probe head, a sound window is installed at the lower end of the probe box. The sound window is used to isolate the probe from the human skin. In order to seal the probe head and other components in the probe box.

Because the sound window is a one-time consumable, the sound window will be removed after one use, but the sound window is transparent. After removing the sound window, it is difficult for medical staff to identify whether a sound window is installed on the probe box. The sound window is installed for detection. The detection head is likely to be in direct contact with the human body, the probe will cause harm to the human body, and it will also crush the detection head.

Therefore, before the mammography machine is used, it is very important to detect whether the sound window is in place. If it is detected that the sound window is not in place, the medical staff should be warned, and the mammography machine cannot detect it.

The traditional sound window in-situ signal detection is achieved by sensors (such as position switches, light sensors, etc.), the cost is relatively high, and the reliability is not very satisfactory (such as the position switch is prone to failure after a long life, the light sensor is easy to Interference by oil, etc.), and the installation and fixing of the sensor itself is also more complicated.
