Ultrasound bone densitometer with full-dry calcaneus bone mineral density ultrasound probes

Abstract

The invention discloses an ultrasound bone densitometer with full-dry calcaneus bone mineral density ultrasound probes. The ultrasound bone densitometer meter comprises a densitometer shell, the top face of the densitometer shell is provided with a detection chamber, the full-dry calcaneus bone mineral density ultrasound probes which can adapt to different foot breadths of people subjected to detection through elastic stretching and retracting are installed on the chamber walls on the left side and the right side of the detection chamber respectively, and adhesive extruding holes are formed in the peripheries of acoustic windows of the dry calcaneus bone mineral density ultrasound probes; a storage tank used for storing an ultrasonic coupling agent is installed in the densitometer shell, a pedal switch which send out an extruding command through pedaling and enables the ultrasonic coupling agent in the storage tank to be extruded out to the skin on the two sides of the calcaneus of people subjected to detection is arranged on the bottom face of the detection chamber; the temperature of the extruded ultrasonic coupling agent is similar to the temperature of a human body. According to the ultrasound bone densitometer, the problem that inconvenience is caused when a traditional probe uses coupled liquid is solved, and the ultrasound bone densitometer can be widely applied to hospitals, clinics and drugstores and can also be applied to the aerospace field to conduct continuous monitoring on the bone mineral density situations of astronauts.

Description

technical field [0001] The invention belongs to medical instruments, and relates to a detector for measuring the bone density of the calcaneal bone of a human body by using ultrasonic waves, in particular to an ultrasonic bone density meter with a fully dry ultrasonic probe for the bone density of the calcaneal bone. Background technique [0002] The detection and measurement of human bone density and bone health using ultrasound technology has been gradually accepted by people. Compared with traditional detection methods such as double X-ray absorption method and quantitative CT, ultrasonic technology has many advantages such as low price, convenient use and no radiation. According to the measurement site, the currently commonly used ultrasonic bone density testing methods include calcaneus bone density, radius bone density, and phalanx bone density. Among them, the calcaneus bone mineral density is measured by the double-probe method of one send and one receive. The sound...

AI Technical Summary

Problems solved by technology

In order to make the measurement results reliable, the conventional calcaneal bone density probe needs to be coupled with a water bath or an oil capsule, which is not only inconvenient for measurement, but also easily leads to liquid leakage, reduces the service life of the equipment, and even damages the equipment
