治疗颌面部化脓性炎症,动脉内注射抗生素比内服、肌肉或静脉注射有效,因为能使进入病灶的抗生素达到较高浓度,不通过肺、肝等生理屏障,药物在组织内的弥散较好,显然能提高疗效。但是现在还未普遍应用,部分原因是由于导管护理和预防血栓形成较复杂,多次用注射器给药有空气栓塞的危险等。作者为使操作简化并减少并发症,用加温定量输液器,它为一金属容器,用弹性隔膜分成两个小室,第1个小室充满抗生素溶液,有可多次加药的橡皮塞口,有输出管能和导管接通,定量结构是水压节流阀。第2个小室充满氟氯烷液,在患者体温作用下沸腾,造成一定压力,经过弹性隔膜挤压第1小室的药液,使其经输出管
Treatment of maxillofacial purulent inflammation, intra-arterial injection of antibiotics than the oral administration, intramuscular or intravenous injection, because it can enter the lesions of antibiotics to a higher concentration, not through the lungs, liver and other physiological barriers, drug dispersion in the tissue better , Obviously can improve the curative effect. However, it is not yet widely used, due in part to the more complicated catheterization and prevention of thrombosis and the risk of air embolism with multiple syringe administrations. In order to simplify the operation and reduce the complications, it uses a warm quantitative infusion set, which is a metal container and is divided into two chambers by an elastic membrane. The first chamber is filled with antibiotic solution, The output tube can be connected with the catheter, the quantitative structure is a water pressure throttle valve. The second chamber filled with fluorochloromethane liquid, boiling in the patient's body temperature, resulting in a certain pressure, squeezed through the elastic membrane of the first chamber of the liquid to make it through the output tube
