Description

Special bed for ultrasonic examination

Technical Field

The invention relates to the field of medical human body ultrasonic examination, in particular to a special bed for ultrasonic examination. Can help the body position of the checked person to change to the organ position checked by the doctor, and help the ultrasonic doctor to obtain the optimal space point for operating the ultrasonic probe.

Background

The development of science and technology has led to the development of more and more means and tools for detecting the organs of the human body, and ultrasonic waves are an important tool for these means, and have the advantages compared with other means for checking the human body, such as: compared with the nuclear magnetic examination and photography, the nuclear magnetic resonance imaging device has no nuclear radiation to hurt the human body (secondary), and can detect almost all organs of the human body along with the continuous breakthrough of the ultrasonic technology.

At present, ultrasonic examination is that an examinee lies on a bed, an ultrasonic doctor holds a probe right hand and manipulates an ultrasonic device left hand to examine the examinee, the device position is basically placed on the side of the head of the examinee, the position is favorable for the doctor to examine in the maximum range, but due to individual differences of human bodies, in some cases, the doctor has to get up (sometimes can not get up) or often requires the examinee to move and turn around in the bed in order to better examine the examinee (patient), and the method is very inconvenient and humanized for the patient or the elderly.

The examination bed used in the prior art is a four-leg bed which is a traditional four-leg bed for thousands of years, and adopts a fixed structure. With the continuous progress of research and development technology, patent documents and patent numbers: 201920223945.8, the name is: a medical ultrasonic examination bed convenient to adjust. The technology makes the bed board mechanism form a chair shape through the stretching movement of the electric telescopic rod, so that the patient can conveniently move to the bed. Another patent document exists, patent number: 202210561697.4, the name is: a multifunctional ultrasonic examination bed. The technology gives instructions for changing the posture of a patient in the examination process according to different detection parts, scans the posture of the patient through a scanning module and displays the posture through a posture display; meanwhile, the U-shaped grooves are formed by turning over the two sides of the bed body in the middle and are used for limiting the actions of infant patients, so that the safety of the infants can be protected and the detection efficiency can be improved while the detection is convenient.

In summary, although the existing examination couch can perform a part of telescopic movement, the use requirements of the current doctors and the current requirements are not met, for example: when the doctor is far away from the part to be detected of the inspected person and the inspection bed cannot move, the doctor is still required to rise or move the inspected person to perform inspection; or when the patient is inconvenient to move or has no mobility, the doctor can check the patient to be checked, and the doctor can finish the examination by assisting personnel or family members.

Thus, current ultrasound examination beds do not meet their operational requirements. It is necessary to provide an ultrasonic examination table which is humanized for medical examination and convenient for doctors to use by the examined person.

Disclosure of Invention
