Anti-collision device for mobile medical equipment

The present invention relates to an anti-collision device for a mobile medical device, and more particularly to an anti-collision device for a mobile medical device combined with a camera.

Today's medical routine inspections often use X-ray equipment. In addition to the fixed X-ray equipment, there are mobile X-ray machines that are more convenient to use in a variety of environments, while mobile X-ray machines are used to avoid taking pictures during surgery, serious or inconvenient patients in the ward. Running between the examination rooms can also reduce the possible damage caused by the above-mentioned patients' movement and ensure the safety of the critically ill patients.

In the mobile traditional X-ray equipment, although the volume and weight are relatively light and lightweight, it still has a certain size and weight due to complicated accessories, which in turn causes flexibility and convenience when moving, and the operator moves X-ray. When the camera is used, it is easy to cause poor visibility in the front because of the large size. It is more difficult to control because the weight of the machine is too heavy. When the line of sight is not good, it is impossible to know in advance whether there are obstacles or people in front, and it is often known that the machine is in the machine. Excessive manipulation is difficult and cannot be stopped or turned immediately. Therefore, mobile X-ray machines frequently cause collisions in medical institutions. The cost of X-ray equipment is not as high as the cost of repairs caused by collisions. In addition, it is even more unimaginable if pedestrians or children are involved in the front and even after the patient collides.

In order to improve the mobile X-ray equipment that can be quickly, conveniently and safely operated by each operator, how to solve the above-mentioned lack of the prior art is a subject that is pursued by those involved in this industry.

Therefore, in order to solve the above problems, the purpose of the present invention is to provide an anti-collision device for a mobile medical device, by combining a mobile medical device and an anti-collision device. In order to solve the inconvenience caused by the operator when moving the medical equipment, it can also reduce the operation time and improve the operation safety.

Sending to the distance determining device, the distance determining device respectively generates a normal traveling control signal, a deceleration traveling control signal, and a stop control signal to the motor control circuit according to the obstacle object distance and the distance reference value, and then The motor control circuit controls the normal travel, deceleration or stop of the drive motor.

The anti-collision device further includes an image capturing device connected to the processing unit via the image processing device, wherein the image capturing device is disposed at a position in front of the moving device facing the moving direction to capture the medical device. An image of a obstacle object that exists in front. The image capturing device can also incorporate a display device.

The distance determining device generates an alert signal to a warning device when determining that the obstacle object distance is less than the distance reference value. The warning device comprises an audible warning device and a illuminating warning device.

The anti-collision device of the mobile medical device further includes a predetermined object image data storage device connected to the processing unit and storing at least one image pixel depth signal of the predetermined object.

In terms of effects, through the above-mentioned technical means adopted by the present creation, the operator can easily grasp the front road condition by simply using the anti-collision device of the present invention when moving the X-ray diagnosis and treatment equipment, thereby solving the operator's movement. The inconvenience caused by the diagnosis and treatment equipment, and the device is equipped with a warning device, which enables the operator and the pedestrians in front of the device to simultaneously achieve the warning effect, reducing the operation time and improving the mobile safety in all aspects.
