目前对皱瘪指掌手印捺印方法主要有皮下注射液体石蜡油加温法、1%KOH浸软法等,这些方法不仅繁琐而且效果差。为此,我们应用沸水膨胀固定法进行了手印捺印的研究。本实验用指掌取源于1988-1990年间案件中腐败或高度腐败尸体。提取的皱瘪指掌由于腐败条件不同表皮呈两种状态:一种是由于尸体掩埋于干燥的地下或长期在干燥环境中指掌表皮呈干燥性皱瘪;另一种是由于尸体掩埋在较湿的地下或长期浸泡在水中指掌表皮形成一层滑腻粘稠样腐败物呈湿性皱瘪。将提取的右手(或左手)用温水浸泡,并用毛刷轻轻刷去指掌表面泥土、附着物,然后用酒精、乙醚棉球轻擦几遍,使表面清洁。注意不要用力过大而使表皮脱落;
At present, the methods of wrinkling, defatting, fingerprinting and stamping mainly include subcutaneous injection of liquid paraffin oil heating method and 1% KOH immersion method, which are not only cumbersome but also ineffective. To this end, we apply the method of boiling water swelling fixed fingerprint research. This experiment used fingerprints derived from the corpse of corrupt or highly corrupt cases from 1988 to 1990. Extracted wrinkled palm due to different spoilage conditions were two kinds of epidermis: one is due to the body buried in a dry underground or long-term dry skin in the palm of the fingers were dry wrinkles; the other is due to the body buried in a wet The underground or long-term immersion in the water refers to the palm of your hand to form a layer of oily skin sticky sticky decay was wet wrinkled. Soak the extracted right hand (or left hand) with warm water, brush gently with a brush to the surface soil and attachments, and then gently wipe the surface with alcohol and ether cotton balls several times to clean the surface. Be careful not to use excessive force to make the epidermis fall off;
