Installation method of ultrasonic probe isolation sheath

Technical Field

The invention relates to the technical field of medical instruments, in particular to an installation method of an ultrasonic probe isolation sheath.

Background

The ultrasonic examination is widely applied to clinic and plays an important role in diagnosis and treatment of diseases. The ultrasonic probe is one of the most important parts in the ultrasonic equipment, but the probe is repeatedly contacted with the skin of a patient, so that the carrying quantity of bacteria is large, and the potential safety hazard of cross infection exists. To avoid cross-contamination, it is common practice in the clinic to sterilize the ultrasound probe or use a disposable ultrasound probe isolation sheath. The ultrasonic probe is sterilized once every time one patient is examined, which has the problem of operability. Therefore, various types of disposable ultrasound probe isolation sheaths have been clinically developed.

Chinese patent CN201420834822.5 discloses an ultrasonic probe sterile protective sleeve. This aseptic protective sheath of ultrasonic probe includes protective sheath body and elastic webbing. The protective sheath body includes hollow silica gel head, connecting portion and fixed part. The inner surface of the head of the silica gel is attached with an ultrasonic coupling agent, a first elastic band is arranged between the head of the silica gel and the connecting part, and a second elastic band is arranged at the tail part of the fixing part. However, this patent uses conventional liquid ultrasound couplants for sound transmission, which still require the application of the couplant to the patient's skin prior to use. In addition, the protective sleeve is fixed in an elastic belt mode, and the use is inconvenient. The silica gel head designed by combining the shape of the probe limits the compatibility of the protective sleeve to ultrasonic probes with different shapes.

Chinese patent cn201620671182.x discloses a novel aseptic ultrasound probe isolation sheath. The ultrasonic probe specifically comprises a sterile liquid ultrasonic couplant which is fixed on a soft silica gel patch at the front end and protected by a tearable strip, wherein the tearable strip is torn during use to carry out ultrasonic examination, the couplant does not need to be coated on the skin of a patient, and the ultrasonic probe isolation sheath and the probe are fixedly pasted through a magic tape. But this patent is fixed the protective sheath through strap and tightening belt, and it is inconvenient to use. Moreover, the film body wraps the whole probe, so that the compatibility of the protective sleeve to probes of different shapes is limited.

Chinese patent CN201710070740.6 discloses an ultrasonic probe protective sleeve. The protective sleeve comprises a bottom lining, an outer material and an inner material. The ultrasonic probe enters the top end through the open end of the bottom lining and is pressed against the top end of the bottom lining through the fixing belt. The outer material and the inner material are bonded on the corresponding outer part and the corresponding inner part of the top end of the bottom lining, the outer material is used for the sound transmission coupling of the skin side of a patient, and the inner material is used for the sound transmission coupling of the ultrasonic probe side. However, the ultrasonic probe is fixed by the fixing band and the elastic band, and the use is complex.
