【摘要】：為了解決殼聚糖和膠原蛋白可吸收縫合線制備工藝中縫合線線徑粗細不均、抗張強度不均的問題,設(shè)計了可吸收縫合線恒張力控制系統(tǒng)。檢測裝置采用敏感元件為電阻應變片的三輥式張力傳感器;控制算法采用PID算法;執(zhí)行裝置采用變頻調(diào)速三相電機。實驗證明:恒張力控制系統(tǒng)能將被控張力誤差控制在±0.1 N以內(nèi),實時性好,可靠性高,制作出的縫合線完全符合美國藥典第32版中膠原縫合線的標準。
[Abstract]:In order to solve the problem of uneven diameter and tensile strength of suture line in the preparation process of chitosan and collagen absorbable suture, a constant tension control system for absorbable suture was designed. The detecting device adopts three roller tension sensor with sensitive element as resistance strain gauge, pid algorithm with control algorithm and three phase motor with variable frequency speed regulation. The experiment shows that the constant tension control system can control the error of controlled tension within 鹵0.1 N, has good real-time performance and high reliability. The suture made by the system conforms to the standard of collagen suture in American Pharmacopoeia 32 edition.
