1.胆甾型液晶(Cholesteric liquid crystal)是一种很好的温敏材料,国内外近十余年来已先后用于诊断肿瘤。诊断肿瘤时大多是采取涂抹液晶法(即把液晶涂在肿瘤部位皮肤上,涂液晶前要先涂上黑色成膜物质或先粘附黑色薄膜),这种方法虽较简单,但因为是临时涂抹,所以在医院门诊应用上仍感不便。为了使液晶诊断方法简化并得到进一步推广,我们开展了胆甾型液晶涂料和诊断肿瘤的液晶膜的研制工作。本文简要地叙述了一种液晶树脂胶涂料(WQ—1型)的制法以及用此涂料制备诊断肿瘤的液晶膜的方法。也叙述了对这种膜的理化特性进行实验观察所得到的初步结果。2.用液晶树脂胶涂料所制的诊断肿瘤的液晶膜是一种可长期反复使用的液晶固定膜。从试制品看,该膜感温敏感,膜薄色亮,所用材料来源广,制造工艺简单,膜面光滑。已经试用于临床,对25例病人进行了病情诊断,与原来使用的涂抹液晶诊断法进行对照,结果一致。3.诊断肿瘤的液晶膜与过去本研究室仿制成功的微胶囊液晶膜(Microencapsulatedliquid crystal film)相比有较多的优越性。新制品可作为一种诊断身体浅层肿瘤的辅助工作使用,也可用于其他目的。这不但简化了液晶诊断肿瘤的方法,便于广泛地推广使用,也扩大了液晶材料的用途。4.本文也简略地叙述了用于检测红外光、激光的液晶屏的制法及其在红外成象、检测激光等方面的初步应用。
1. Cholesteric liquid crystal (Cholesteric liquid crystal) is a good temperature-sensitive materials, at home and abroad for more than 10 years has been used to diagnose the tumor. Most of the time to diagnose tumors by smear LCD method (that is, the liquid crystal coated on the skin of the tumor, the first coating of liquid crystal coated with black or first attached to the black film), although this method is relatively simple, but because it is temporary Smear, so the application is still inconvenient in the hospital clinic. In order to simplify and further promote the diagnosis of liquid crystal, we carried out the development of cholesteric liquid crystal coatings and liquid crystal films for the diagnosis of tumors. This article briefly describes a method for preparing a liquid crystal resin coating (WQ-1 type) and a method for preparing a liquid crystal film for diagnosis of tumors using the coating. Also described the physical and chemical properties of this film experimental observations obtained preliminary results. 2. With liquid crystal resin coating made of the diagnosis of tumor liquid crystal film is a long-term repeated use of liquid crystal fixed film. From the trial products, the film temperature sensitive, thin film bright color, the source of a wide range of materials used, the manufacturing process is simple, smooth membrane surface. Has been tried in clinical, 25 patients were diagnosed with the original smear LCD diagnostic method used for control, the results are consistent. 3. The diagnosis of tumor liquid crystal membrane and the past, the successful imitation of the microcapsule liquid crystal film (Microencapsulatedliquid crystal film) compared to have more advantages. New products can be used as a diagnosis of superficial tumors of the body auxiliary work, but also for other purposes. This not only simplifies the liquid crystal diagnosis of cancer methods, to promote the widespread use of, but also expanded the use of liquid crystal materials. 4. This article also briefly describes the method used to detect infrared light, laser liquid crystal screen and its preliminary application in infrared imaging, laser detection and so on.
