Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a heart ultrasonic probe convenient for smearing a couplant, which is used for heart ultrasonic image acquisition in laboratories and the like in the fields of biology and medicine, and reduces the time-consuming of frequently taking and placing the couplant in the image acquisition process.
Background
Heart color Doppler ultrasound is the most widely used means for heart disease examination in clinic at present, and can dynamically display the intracardiac structure, the pulsation and the blood flow of the heart. The heart super probe looks like a camera lens, and various structures of the heart are clearly displayed on a screen along with the rotation of the probe. In ultrasonic examination, the cavity of the probe, which is in contact with the skin, is necessarily filled with air, so that a large acoustic impedance difference is generated. When the ultrasonic waves emitted by the probe head travel to the air interface, the strong emission effect causes that the ultrasonic waves cannot enter the human body basically, so that the imaging fails and the diagnosis inspection cannot be completed.
The ultrasonic couplant is water-soluble polymer gel used for filling between the probe and the skin to eliminate air interference, reduce loss of sound waves, facilitate smooth passage of ultrasonic waves and enter the human body to the greatest extent. In addition, the couplant can keep moist and sticky for a long time, plays a role of lubrication, can ensure flexible sliding exploration of the probe, and can prevent the skin friction caused by sliding in the probe inspection from being stimulated and damaged.
In the process of cardiac ultrasonic inspection, an operator repeatedly takes and puts and extrudes the couplant bottle for many times, even in one inspection, the condition that the couplant is repeatedly smeared for many times is likely to happen, the tedious and repeated process tends to increase the working intensity of the operator, prolong the inspection time and reduce the overall inspection efficiency. In addition, as the operator often directly smears the couplant on the surface of the skin to be inspected, if a plurality of body surfaces of the same patient are to be inspected, the couplant is easy to cause overlarge smearing range, and the waste of the couplant and the difficulty of wiping and cleaning are inevitably caused. Meanwhile, the extrusion quantity of the couplant is unstable due to the difference of extrusion force of the couplant bottle each time, so that the inspection result is influenced, unnecessary waste is generated, and the inspection cost is increased.
In order to solve the problem of smearing an ultrasonic couplant, chinese patent discloses an ultrasonic probe and a B-ultrasonic diagnosis and treatment device (CN 110013268A), wherein a coupling liquid bag is arranged at the end part of the ultrasonic probe, and the coupling liquid bag is extruded through a telescopic mechanism, so that the front end of the ultrasonic probe can always keep a certain thickness of coupling liquid, and the time for smearing the couplant back and forth is saved.
However, the process is not limited to the above-mentioned process,
the coupling liquid bag and the telescopic mechanism have certain thickness, and in clinic, the couplant is directly filled between the probe and the skin to be most beneficial to ultrasonic development. Therefore, the device with the coupling liquid bag and the telescopic mechanism can influence the detection imaging quality of the ultrasonic probe and influence the inspection result.
