Description

Heating ultrasonic probe integrating cleaning and smearing of couplant

Technical Field

The invention relates to the technical field of medical instruments, in particular to a heating ultrasonic probe integrating smearing and cleaning of a coupling agent.

Background

The ultrasonic technology is widely applied in the medical field, the ultrasonic wave plays an important role in the aspects of disease condition examination, diagnosis and the like, and the ultrasonic diagnosis examination generally utilizes an ultrasonic probe, wherein the ultrasonic probe is a device for transmitting and receiving the ultrasonic wave and is a transducer for converting electric energy and sound energy by utilizing the piezoelectric effect of materials. The existing clinical ultrasonic detection generally comprises B-type ultrasonic, M-type ultrasonic and D-type ultrasonic, and the B-type ultrasonic (B-type ultrasonic) is most applied. During ultrasonic examination, air between the probe and the patient's skin will prevent the transmission of ultrasonic waves into the body, and in order to obtain high quality images, a liquid conductive medium is required to connect the probe to the patient's body surface, which is the coupling agent.

Ultrasonic probe need cooperate the couplant to use, in current clinic, ultrasonic probe inspection and the paining of couplant often separately go on, need medical personnel to paint the couplant in advance on the skin surface of the big position of waiting to examine of patient, later cooperate the probe to detect again, to some large tracts of land and long-time inspections, for example pregnant woman, often need to add the couplant many times in the inspection process, need medical personnel's operation that pauses ultrasonic probe to wait that the couplant paints and then resumes, but because the picture of ultrasonic probe inspection is interrupted, when reexamination, need look for the inspection angle and the position of interruption before the time of looking for again, except that complex operation, the check-out time has been prolonged greatly, still arouse the omission of inspection position easily, influence the accuracy of disease inspection, delay the state of an illness very easily.

In addition, the couplant is jelly with low temperature, so that the couplant is smeared on the body surface of a patient at about 37 ℃ to cause stimulation to the patient, and a large amount of couplant on the surface of the skin after examination is difficult to thoroughly clear away due to the oil and fat, easily pollutes clothes, influences the comfort and causes more burden to the patient who is uncomfortable or inconvenient to the body.
