在美国卡尔曼负压空针的基础上.南京市设计了一种新型的塑料负压人流器(称NS—1型塑料负压人流器).外形似50毫升注射器,重88克,由塑料筒芯和橡胶零件组成.塑料筒芯上设有四块档板,每档板间容量各15毫升.容量越大,负压越高,最大负压为600毫米汞柱.负压和容量可根据临床需要而调节.避免不必要的过大负压,可减少
Based on the American Karman negative pressure needle, Nanjing has designed a new type of plastic negative pressure flow absorber (called NS-1 plastic negative pressure flow absorber), which looks like a 50ml syringe with a weight of 88g and is made of plastic Core and rubber parts. There are four baffles on the plastic core with a capacity of 15ml between each baffle. The larger the capacity, the higher the negative pressure, the maximum negative pressure is 600mmHg. Negative pressure and capacity can be Adjust according to clinical needs to avoid unnecessary negative pressure can be reduced
