Embodiment 1

[0049] Figure 2 to Figure 12 An ultrasonic diagnostic device provided by an embodiment of the present invention is shown. The ultrasonic diagnostic equipment includes an ultrasonic host and an ultrasonic probe.

[0050] Since different substances or tissues in the human body have different densities and hardnesses, they each have different sonic impedances. Ultrasound imaging is a method of scanning the human body with ultrasonic sound beams, and obtaining images by receiving and processing reflected signals. Due to the advantages of real-time imaging and low cost, ultrasound imaging is widely used in the medical field. The ultrasonic probe contains an ultrasonic transducer, which is a piezoelectric crystal component that resonates at an ultrasonic frequency. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. Ultrasonic transducers are both transmitters and receivers. That is, sound waves can be radiated into the tissue to be ...

Embodiment 2

[0072] The embodiment of the present invention provides an ultrasonic pupil measurement method, which is applied to the ultrasonic diagnosis in Embodiment 1, such as figure 1 As shown, the ultrasonic pupil measurement method mainly includes:

[0073] Step S10: Obtain a pupil image including changes in pupil diameter by controlling the operation of the ultrasound probe and controlling the brightness change of the light source device when the pupil measurement instruction is received;

[0074] The ultrasonic probe collects two-dimensional image data of the tissue to be measured and transmits it to the ultrasonic host. The control of turning on, turning off and brightness of the light source device can be realized through the control device on the ultrasonic host and / or the ultrasonic probe. When the instruction of pupil measurement is received, the opening, duration, brightness adjustment and closing of the light source device are automatically controlled by the automatic measu...

Abstract

The invention provides an ultrasonic pupil measurement method, an ultrasonic host and ultrasonic diagnosis equipment, and the method comprises the steps: controlling an ultrasonic probe to work and controlling the brightness change of a light source device when a pupil measurement instruction is received, so as to obtain a pupil image containing the pupil diameter change; calculating the pupil diameter of the pupil image; and displaying the change curve of the pupil diameter. The ultrasonic pupil measuring method is based on a ultrasonic imaging principle, automatic measurement can be achieved without pushing open eyelids of a patient, the method can be suitable for special scenes such as coma, severe coma and burns, the light source device is controlled to be turned on and turned off, and the light response sensitivity of pupils is evaluated in combination with the turning-on and turning-off time of the light source device, including the pupil size, the pupil contraction rate, the pupil reduction rate and the like, and an important treatment and diagnosis basis is provided for medical clinic.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to an ultrasonic pupil measurement method, an ultrasonic host and ultrasonic diagnostic equipment. Background technique [0002] The size and change of pupil diameter are important indicators of clinical detection. The regular and quantitative monitoring of pupil can reflect physiological awakening, reflect and evaluate autonomic nervous activity, reflect heart rate changes and realize non-contact and non-injury measurement of heart rate variability; it is helpful for coma, Judging the condition of patients with convulsions, shock, poisoning, respiratory failure and circulatory failure, especially for patients with craniocerebral injury, it can determine the location of intracranial injury. Effective, timely, and dynamic observation and evaluation of pupillary changes can not only detect the aura of the disease, seize the best and more opportunities for treatment, ...
