Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ultrasonic equipment, especially a novel eye color doppler ultrasonic diagnostic instrument. BACKGROUND

[0002] The eye color doppler ultrasonic diagnostic mechanism is a commonly used device in the ophthalmology department of the medical department, which can not only find common diseases of the eye, but also display the blood vessel conditions around the eye. Specifically, the following diseases can be found through the eye color doppler ultrasonic diagnostic mechanism inspection: vitreous opacity, posterior vitreous detachment, retinal detachment, choroidal detachment, choroidal retinal tumor, vitreous hemorrhage, diabetic retinopathy, and other vitreous and fundus lesions. In addition, it can also detect whether there are foreign bodies in the eyeball after an eye injury, whether the eyeball is ruptured, whether the eye muscles are abnormal, whether the ophthalmic artery and vein are abnormal, and so on.

[0003] Although the existing eye color doppler ultrasonic diagnostic mechanism meets the needs of clinical examination to some extent, it is limited by structure and function, and more or less has the following technical defects. First, it does not have a display screen angle and height adjustment function. When the examiner needs to adjust the angle of the display screen, he can only manually rotate and adjust the position of the entire device to adjust the angle of the display screen. Since the overall shape and weight of the device are relatively large, and the space is limited on site, it will be inconvenient for the examiner to adjust. Since the height is not adjustable, the examiner can only manually adjust the height of the seat to adapt to the height of the operation keyboard of the eye color doppler ultrasonic diagnostic mechanism to facilitate the operation of the related operation keys. When the height difference between different examiners is large, manual adjustment is required before each use, which will also be inconvenient for the examiner to adjust. Second, it does not have an automatic disinfection function for the ultrasonic probe. Under normal circumstances, after the examination of the previous patient is completed, the examiner will not disinfect the ultrasonic probe, which will increase the risk of virus transmission (even if the examiner disinfects the ultrasonic probe, it is a manual way to spray disinfectant on the ultrasonic probe, which will also be inconvenient for the examiner). In summary, it is necessary to provide an eye color doppler ultrasonic diagnostic mechanism that can conveniently adjust the angle of the display screen and the height of the entire device, and can automatically disinfect the ultrasonic probe when not in use.

[0021] Figure 1 、 2, 3, 4, when the doctor checks, because the ultrasonic probe of the eye color Doppler ultrasound diagnostic equipment body 1 is not located in the barrel 21, the ultrasonic probe does not shield the probe of the photoelectric switch U2, then the 3 foot of the photoelectric switch U2 does not output high level, in this way, the liquid pump M2 cannot work, the nozzle lower end of the nozzle 22 (and the nozzle structure of the sprayer is consistent) cannot spray the alcohol disinfectant liquid. When the doctor checks, the ultrasonic probe 107 is inserted into the barrel 21 through the insertion port 26, the ultrasonic probe 107 is located on the upper part of the fixed port, after the ultrasonic probe 107 is located in the barrel, the rear end thereof shields the probe of the photoelectric switch U2, the 3 foot of the photoelectric switch U2 outputs high level into the positive power input end of the time control switch U3, the 3, 4 foot of the time control switch U3 outputs certain time power (for example, 3 seconds) into the power input end of the relay J1, the control power input end and the normally open contact end of the relay J1 are closed in the time of the relay J1 being electrified, the liquid pump M2 is electrified to work to extract the alcohol in the disinfectant tank 24, then the alcohol is sprayed from the nozzle lower end to spray and disinfect the upper end of the ultrasonic probe 107; after 3 seconds, the control power input end and the normally open contact end of the relay J1 are opened, the liquid pump M2 is de-energized and does not work, and the nozzle does not spray the disinfectant liquid. In the specific application, when the liquid amount in the liquid tank 24 is relatively large, the internal contact of the liquid level switch W1 is opened, and the buzzer B does not generate sound. When the liquid amount in the liquid tank 24 is relatively small, the internal contact of the liquid level switch W1 is closed, and the buzzer B generates sound. The doctor can hear the prompt sound in time to add disinfectant such as alcohol, so that the whole equipment can be normally used.
