Description
Technical Field
The utility model relates to a medical ultrasonic sound guide pad device, in particular to a conformal medical ultrasonic sound guide pad with adjustable thickness and length.
Background
When the ultrasonic examination of the superficial organ is carried out, because part of focus positions are shallower, the focus positions are closer to the skin and are in the near field of an ultrasonic field, a large number of ultrasonic artifacts exist, lesions cannot be clearly displayed, and clinically, a plurality of smearing couplants are often adopted to increase the distance between a probe and a focus, so that the quality of an ultrasonic image is attempted to be improved. Part of the focus is concave, the probe can not be tightly attached to the focus, the concave is filled by a plurality of smearing couplant in clinic, the gas between the focus and the probe is eliminated, and the ultrasonic inspection quality is improved. However, the couplant used in the current ultrasonic examination is mainly prepared from water-soluble polymer materials, when the temperature is increased, the couplant is easy to thin under the condition of body temperature, and flows everywhere, and the couplant is soft, so that the distance between the probe and the focus is difficult to be controlled stably by a sonographer, and the ideal examination effect cannot be achieved.
Currently, an ultrasonic coupling pad (a platy hydrogel elastomer) is applied to ultrasonic inspection, so that the distance between a probe and a focus can be increased, ultrasonic near-field artifacts can be reduced, and ultrasonic inspection quality can be improved. However, the ultrasonic coupling pad sold in the market at present is a disposable product, has high price and is difficult to popularize and apply. Some ultrasonic doctors try to use the ultrasonic coupling pad for a plurality of times to reduce medical cost, but the sound guiding glue of the commercial ultrasonic coupling pad is exposed to air, so that the ultrasonic coupling pad is difficult to preserve after being started and easy to shrink, deform and crack after being placed for a long time. In addition, most of the materials used for the sound guiding glue are water-soluble polymer substances, and the sound guiding glue is in direct contact with a focus of a patient during ultrasonic examination, so that the sound guiding glue cannot be cleaned and disinfected after being used, and is easy to cause iatrogenic cross infection after being repeatedly used.
Most of the sound guide pads sold in the market at present are square or round cushion blocks, the thickness of each part of the whole sound guide pad is uniform and unchanged, the texture is more tough, and the compressibility is poor. When the focus protrudes out of the skin and the height is uneven, the sound guide pad with constant thickness is difficult to change in shape according to the surface condition of the focus, and the ultrasonic examination effect is obviously affected. In addition, some normal human body structures such as non-horizontal surfaces of elbows, wrists and the like often need to be fully inspected around joints, but the currently marketed ultrasonic coupling pads are much smaller in length, difficult to fully cover a longer range of focus, and are clinically inspected by applying a coupling agent. The multi-smeared couplant easily falls onto the examination bed or the ground and even becomes contaminated on the body or clothing of the subject or even the examining physician.
