Description
Technical field
The utility model belongs to medical instrument quality examination technical field, and in particular to one kind is for transabdominal ultrasonography probe table
The load mould of face temperature measurement.
Background technique
Medical ultrasound diagnostic-custodial care facility be via ultrasonic probe to human body appointed part transmitting certain frequency, intensity and
The ultrasonic wave of form receives, processing reflection-scatter echo signal, and then being shown in the form of image, figure, number, sound etc. should
The physiology and pathological information at position to judge to the presence or absence of disease, damage, property, degree, or join human body physical sign
The complication system that number is monitored.However, sent out ultrasonic wave is while as information carrier and the carrier of power and energy,
By with radiant force, acoustic streaming and tissue resorption sound can after the thermal energy that is converted to act on tissue, can also cause cavitation in some cases,
Cavitation causes high temperature again, high pressure acts on tissue.When acoustic pressure, sound intensity height to a certain extent when, one such or several effects
It will cause disorganization or denaturation, i.e. developmental biology effect.For this purpose, relevant unit it is consistent with brainstrust seek it is appropriate
The output amplitude of physical parameter characterization and control diagnosis ultrasound.But discovery later, causes tissue via ultrasonic probe
Injury, the heat generated there are also inverting element itself and caused temperature rise.For this purpose, International Electrotechnical Commission (IEC) and China

For this demand, United Kingdom National physics laboratory has developed one and is known as " surface temperature detection body mould
The device of (surface temperature test phantom) " ties up in plexiglass cylinder and a layer thickness is perfused about
Agar gel type sound-heat of 11cm imitates organization material, firstly, the title of the device be it is inaccurate, as body mould, it is only
As the tissue substitute of ultrasonic probe load, rather than a kind of measurement means.In use, temporarily covering a piece of room temperature sulphur
SiClx building rubber compound adult mold device, top surface are in plane.But plane sound window is only applicable to plane antenna probe, is not suitable for facing
Most of convex array probe is accounted for used in bed；In addition, its interior sound path is too short, the effective attenuation of ultrasonic wave, and its side not can guarantee
Wall heat transfer is bad, will lead to the deviation of surface temperature of probe measured value；Its Open architecture will lead to liquid evaporation loss, thus
The change of imitative organization material sound-thermal characteristics is caused, therefore is simply possible to use in short-term research experiment, cannot function as the long-term (number of fixed equipment
Year) use.Furthermore Open architecture, which also results in, to be used in a water bath.
