​What is the gel applied for ultrasound examination?

Health care workers who perform ultrasound examinations always apply a layer of clear gel before touching the probe with the examiner. You might think it’s a lubricant, but that’s just a secondary role. The official name of this gel is Ultrasonic Coupling Agent, and its main purpose, as its name suggests, is as a medium for “coupling”. Ultrasonography scans the human body with ultrasound waves (frequency greater than 20 kHz) that are inaudible to the human ear, and converts the echo signals into image information inside the body. B-ultrasound presents black and white images with different brightness (Brightness), while color Doppler ultrasound presents the blood flow of tissues in color on this basis. However, as a mechanical wave, the propagation of sound waves is affected by changes in the medium. Although the probe of the ultrasound equipment is next to the skin, the dry contact is inevitably separated by air. Due to the large difference in acoustic impedance between the air and the human body, two completely different media, sound waves will be reflected a lot at the interface between the two, and a lot of sound energy has been lost before entering the human body. In order for sound...

Effect of B-Ultrasound on Cattle in Preventing Termination of Pregnancy in Dairy Cows

Reproductive obstacles caused by extensive management and overuse of dairy cows in production: due to extensive management, no lactation period, dry milk period, even regardless of size, mixed group feeding under the same ration formula, resulting in poor body condition of lactating cows, cattle The backfat thickness of lactating cows is poorly checked with B-ultrasound. Breeding cows and dry dairy cows are too obese when examined by B-ultrasound, resulting in low reproductive function of the whole herd of cattle. Excessive utilization and blind pursuit of high milk yield lead to reproductive obstacles in dairy cows. There are cases in which milk production is increased by increasing the supply of high-protein concentrate feed. The result of this blind pursuit of milk yield can only cause reproductive disorders and digestive problems. Systemic diseases occur frequently. Reproductive obstacles caused by improper breeding techniques of dairy cows: estrus observation time is wrong, insemination cannot be timely, and methods such as monitoring follicles with B-ultrasound are not used; artificial insemination personnel are not skilled in artificial insemination, artificially causing cervical Injury; lax aseptic operation, retained placenta failed to deal with in time, resulting in endometritis; Vaginal prolapse, etc. cannot be diagnosed and treated in time,...
