The size of the haematomas treated with hirudoid was reduced after 24 hours , while the haematomas which remained untreated or were treated with cream base required 24 - 36 hours to show a distinct improvement 血肿的大小在喜疗妥组用药24小时后即减小了，而未治疗组或软膏基质组则需要24 36小时才有明显的改善。
Superficial subcutaneous haematomas are particularly suitable for the verification of the absorption promoting effect of cutaneously administered compounds on corpuscular components and fibrin deposits of extravasates 浅表皮下血肿特别适合用于验证连续应用化合物后，其对渗出物中细胞成分及纤维沉淀物的吸收促进作用。
Thus , hirudoid / hirudoid forte prevent the formation of superficial thrombi , promote their absorption , counteract local inflammatory processes and accelerate the absorption of haematomas and the reduction of swelling 因此，喜疗妥乳膏/特强喜疗妥乳膏能预防浅表血栓的形成，促进它们的吸收,阻碍局部炎症的发展，加速血肿的吸收和具有消肿作用。
If injecting an invariable alternating current into patient ' s brain , the brain edema or haematoma in the brain will change the interal electric field and the distribution of voltage on the brain ' s surface 如果对病人大脑注入此电流，由于病人大脑内部的血肿和水肿改变大脑内部的组织结构，也就改变了的大脑内部的电场和大脑表面的电位分布。
Because coronal haematoma absorptance is slower , avoid by all means is carried with the needle broken , or go drawing blood with injector , can enter a bacterium because of taking instead so and produce infection , cause undesirable consequence 由于头颅血肿吸收比较慢，切忌用针挑破，或用注射器去抽血液，这样反而会因带入细菌而发生感染，引起不良后果。
The second part is a detector which is used to detect the distribution of voltage on the patient ' s brain surface from all different directions . the third is a mixed signal processor ( c8051f020 ) which is used to control the other parts of the system and display some necessary information and convert the voltage signals into digital signals , as well as transmit the acquired data to the computer . the fourth is computer with eit software which is used to analyze and process the received data and construct a picture for the brain edema and haematoma on screen 32通道电阻抗断层成像系统由4个部分组成：第一部分是正弦波恒流源，用来产生注入大脑的激励电流；第二部分是电位信号的提取与转换，用来提取当激励电流注入时，在大脑表面形成的电位分布信号；第三部分是数据采集与控制系统，用来控制激励电流的频率，注入方向，注入强度，控制采集大脑表面的电位分布信号，并且将这些采集的电位分布数据传到pc机；第四部分是计算机eit成像软件，用来接收下位机的电位分布数据，并且对这些数据进行分析计算，重建电阻抗图像。
If injecting an invariable alternating current into patient ' s brain from all directions , and detect the distribution of voltage on the brain ' s surface which reflect the brain ' s internal information about impedance , then use computer to analyze the distribution of voltage detected by sensors , so that localizes the position and constructs an image for the brain edema and haematoma 将一个小的交变电流从大脑不同的方向注入，就会在大脑表面产生不同的电位分布，通过检测大脑表面的电位分布，用计算机来对这些分布的电位进行分析、计算、定位和重建水肿血肿的图像。
Diagnosing and constructing an image for the brain edema and haematoma mainly depends on ct or mri , but they are expensive , so it is impossible to frequently use ct or mri to monitor patient . it is necessary to develop the 32 channels eit system to show the process of the evolution of brain edema and haematoma 目前ct和mri是作为诊断水肿和血肿的主要手段，水肿，血肿病人的病情发展很快，然而ct和mri造价昂贵，体积庞大，不可能频繁的用ct和mri来监测病人的病情，所以有必要研制32通道的电阻抗断层成像（ eit ）系统来监测血肿水肿的演变过程。
Go out for advantageous and fetal childbirth , the doctor employs obstetric forceps or fetal head is attracted implement will undertake aiding yield , right now fetal head suffers extruding , make coronal bone overlaps , the head surrounds decrescent , cause the blood - vessel below periosteum likely to get hurt burst , blood builds up slowly a haematoma 为了有利胎儿娩出，医生动用产钳或胎头吸引器来进行助产，此时胎儿头部受挤压，使头颅骨重叠，头围变小，就有可能造成骨膜下血管受伤破裂，血液慢慢积聚成一个血肿。
