Aparell de diagnòstic per ultrasons Oftalmologia AB (AB)

La nostra empresa té tots els drets de propietat intel·lectual independents d’aquest producte i ha obtingut diversos certificats de patents. El producte ha assolit el nivell avançat internacional i líder nacional en la precisió de la mesura, l’error de mesura i la qualitat d’imatge d’escaneig B de l’ecografia A, especialment l’aplicació clínica, que és més intel·ligent i humana. Els productes s’utilitzen en hospitals de tot el país i han rebut elogis unànimes.


Descripció del producte

L’equip té les següents característiques:

En primer lloc, l’instrument de diagnòstic és lleuger i compacte, amb un rang de tensió ultra ampla de 90V-264V i 50 / 60Hz, que es pot adaptar a diverses situacions complexes.

En segon lloc, el valor de la mesura per ultrasons A és precís i la precisió de la mesura és de 0,02 mm; en ús en hospitals com l'Hospital del Teatre Occidental de Chengdu, l'Hospital del Cos de Policia Armada de Sichuan i el Primer Hospital Popular de Yibin, el personal del servei postvenda va rebre els professors que utilitzaven aquests hospitals quan pagaven una trucada de devolució. Segons la retroalimentació donada, els resultats de la mesura de l’ecografia AB i de l’ecografia A es van comparar amb els resultats reals de la mesura de IOL master i lenstar900 al mateix temps, i l’error va ser de 0,02 mm. Quan es troben amb pacients especials, com ara pacients amb cataractes denses, la super precisió de la màquina A de la nostra empresa també és significativament superior a la d’altres màquines similars. La màquina de la nostra empresa utilitza algoritmes i tecnologia de processament avançats en el processament i identificació de ressons d’ultrasons A. La sensibilitat del ressò és elevada, l’amplada és estreta i permet identificar de manera intel·ligent la cambra anterior, la lent i la retina.

Si la càmera anterior i el ressò de la lent no es poden identificar amb precisió quan es mesura la cataracta compacta, per exemple, si la cambra anterior es mesura amb 2 mm menys de lent i 2 mm més de lent, sentireu que la longitud axial total no ha canviat, de fet (2 /1532*1661-2=0.17), a causa de la diferència de velocitat del so, l'impacte final sobre la longitud de l'eix de l'ull pot arribar a 0,1-0,2 mm.

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.
