안과 AB 초음파 진단 장치(AB)

당사는 이 제품에 대한 모든 독립적인 지적 재산권을 보유하고 있으며 다수의 특허 인증서를 획득했습니다. 이 제품은 A-초음파의 측정 정확도, 측정 오차 및 B-스캔 이미지 품질, 특히 임상 응용 분야에서 보다 지능적이고 인간적인 측면에서 국내 유수 및 국제 선진 수준에 도달했습니다. 제품은 전국의 병원에서 사용되며 만장일치로 찬사를 받았습니다.


제품 설명

장비에는 다음과 같은 특성이 있습니다.

첫째, 진단 기기는 90V-264V 및 50/60Hz의 매우 넓은 전압 범위로 다양한 복잡한 상황에 적응할 수 있는 가볍고 컴팩트합니다.

둘째, A- 초음파 측정 값은 정확하고 측정 정확도는 0.02mm입니다. 청두 서부극장병원, 사천무장경찰대병원, 이빈제일인민병원 등 병원에서 사용하는 병원에서 애프터 서비스 직원이 전화를 걸면 이 병원에서 사용하는 교사를 받았다. 피드백에 따르면 AB 초음파와 A 초음파의 측정 결과를 IOL master와 lenstar900을 동시에 측정한 실제 측정 결과와 비교한 결과 오차는 0.02mm 이내였다. 조밀한 백내장 환자와 같은 특수 환자를 만날 때 우리 회사의 기계 A의 초정밀도 다른 유사한 기계보다 훨씬 높습니다. 우리 회사의 기계는 A-초음파 에코의 처리 및 식별에 고급 처리 기술과 알고리즘을 사용합니다. 에코 감도는 높고 너비는 좁으며 전방, 수정체 및 망막을 지능적으로 식별할 수 있습니다.

컴팩트 백내장을 측정할 때 전방과 수정체 에코를 정확하게 식별할 수 없는 경우, 예를 들어 전방을 2mm 적은 수정체와 2mm 더 많은 수정체로 측정하면 전체 축 길이가 실제로 변경되지 않은 것처럼 느낄 것입니다(2 /1532*1661-2=0.17), 음속의 차이로 인해 눈 축의 길이에 대한 최종 영향은 0.1-0.2mm에 도달할 수 있습니다.

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.
