Ophthalmology AB Ultrasound Diagnostic Apparatus(AB)

Our company has all independent intellectual property rights for this product, and has obtained a number of patent certificates. The product has reached the domestic leading and international advanced level in the measurement accuracy, measurement error and B-scan image quality of the A-ultrasound, especially the clinical application, which is more intelligent and humane. The products are used in hospitals all over the country, and have won unanimous praise.

Product Description

The equipment has the following characteristics:

First, the diagnostic instrument is light and compact, with an ultra-wide voltage range of 90V-264V and 50/60Hz, which can adapt to various complex situations.

Second, the A-ultrasonic measurement value is accurate, and the measurement accuracy is 0.02mm; in use in hospitals such as the Western Theater Hospital in Chengdu, the Sichuan Armed Police Corps Hospital, and the Yibin First People's Hospital, after-sales service personnel received the teachers used by these hospitals when they paid a return call. According to the feedback given, the measurement results of the AB ultrasound and the A ultrasound were compared with the actual measurement results of the IOL master and lenstar900 at the same time, and the error was within 0.02mm. When encountering special patients, such as patients with dense cataracts, the super accuracy of our company's machine A is also significantly higher than other similar machines. The machine of our company uses advanced processing technology and algorithms in the processing and identification of A-ultrasound echoes. The echo sensitivity is high, the width is narrow, and it can intelligently identify the anterior chamber, lens, and retina.

If the anterior chamber and lens echo cannot be accurately identified when measuring compact cataract, for example, if the anterior chamber is measured with 2mm less lens and 2mm more lens, you will feel that the total axial length has not changed, in fact (2/1532*1661-2=0.17), Due to the difference in sound velocity, the final impact on the length of the eye axis can reach 0.1-0.2mm.

Second, the intelligent recommendation function of IOL calculation formula: the instrument automatically recommends SRKT (selected when the long eye axis, eye axis length ﹥25mm), HOFFER-Q (short eye axis, when the eye axis length ≤ 20mm according to the measurement result of the eye axis length Choose), HOLLADAY (normal eye axis, 20mm <when ​​the eye axis length is less than 25mm), the appropriate one of the three formulas and SRK-Ⅱ will calculate the degree of intraocular lens at the same time for doctors to choose. Doctors can also choose one of the five formulas of SRKT, BINKHORST, HOFFER-Q, HOLLADAY, HAIGIS, and SRK-Ⅱ formula to calculate the intraocular lens power at the same time according to their own experience. This feature is our company's first recommendation.

Third, when the measurement error of A-scan is too large, the array will automatically retest. When encountering a more special patient, such as: vitreous turbidity and severe bleeding, the turbidity point and the bleeding point are on the visual axis, and the echo amplitude and position meet the automatic freezing conditions. At this time, the A-scan will use this point as The retinal echo causes a large deviation in the array. If the testing doctor is negligent or is unfamiliar with the use of the instrument and does not manually delete the set of data, the patient may experience excessive deviation in the degree after surgery. In order to avoid this situation, after 9 sets of data measured by our company's A-ultrasound, it is immediately compared with the average value. When there is a large error in one or several sets of measurement data, the system will automatically mark the array with large error and alarm. Measure the marked data. This function is currently only available in our company.

Fourth, the B-ultrasound image is clear, fully digitalized, and the signal is rich and delicate.

Fifth, B-ultrasonic frequency conversion launch, real-time comparison. The transmitting frequency of the B-ultrasound probe can be adjusted in real time from 8MHz to 11MHz. This technology has obtained a national invention patent.

Sixth, B-ultrasound probe drive adopts all-digital subdivision drive circuit, 256 steps, one-step transmission, the drive is more stable, the position accuracy is higher, and the sound and vibration are smaller. This technology has applied for a national invention patent.

Seventh, the detection depth can be adjusted in real time during B-scanning, and the image can be zoomed in and out in real time, so that the doctor can better observe the small lesions.

Eighth, 256 movies are played back frame by frame, and the playback images can be frozen at any time, and screenshots can be selected frame by frame. It is convenient to select and save the typical case map.

Ninth, with the computer and SDK180 operating software, it can realize the operation of saving, recalling and printing cases.
