Description

Auxiliary device for ultrasound department examination

Technical Field

The invention relates to the technical field of medical equipment, in particular to an auxiliary device for ultrasonic department examination.

Background

Ultrasonic examination is a very important disease diagnosis technology in modern clinical medicine, and has the advantages of no wound, wide examination range, low cost and the like. Ultrasound examination is one of medical imaging examinations that assist clinicians in diagnosing disease and also can assess efficacy and guide further treatment. The couplant is a substance which is necessary to be used for ultrasonic examination, the function of the couplant is to facilitate ultrasonic conduction between the probe and the skin or mucosa of a human body, and the using method of the ultrasonic examination is as follows: the patient crouches on the inspection bed, exposes the inspection position, and paint special couplant, then medical staff holds ultrasonic probe and dabs patient inspection position body surface, and constantly moves and carry out the ultrasonic scanning, can demonstrate the multiple tissue image at this position according to the probe position of touching on the display screen of ultrasonic instrument, thereby help medical staff's accuracy to make the judgement, for making the inspection process more smooth, can use auxiliary device to cooperate, however current department of ultrasound inspection has following problem with auxiliary device:

the prior auxiliary device for the ultrasonic department examination needs a patient to lift clothes to expose a part to be examined during the ultrasonic examination, the examination is possibly influenced by unstable support of the clothes during the examination, in addition, the arm is sour and numb and the physical strength is consumed due to the patient keeping the posture of lifting the clothes for a long time, and the clothes are not convenient to support and fix, and a doctor usually uses a cotton swab or a sponge to smear a couplant when smearing the couplant on the patient, or squeezes the couplant to the palm directly, so the smearing mode is very troublesome, the couplant needs to be squeezed from a couplant bottle, the workload is increased for medical workers if the amount is small during the smearing process, the detection efficiency is low when too many patients are detected, and the operation of smearing and squeezing is not convenient, when the couplant is smeared on the body of a patient, the couplant has certain fluidity, so that the couplant can flow from two sides of the body to a lying bed, the subsequent cleaning is required, and the lateral leakage prevention treatment is inconvenient to be carried out when the couplant is smeared.

Therefore, we have proposed an ultrasound examination assisting apparatus in order to solve the problems set forth above.
