目前，一性次止血带一般为为天然像胶制成，呈宽扁型。以条为单位，独立单一包装居多，护理人员使用极不方便，每次使用前须拆解包装、高频次的使用导致工作效能大大降低，不乐意使用。已面市的最新锁扣式连抽式一次性止血带，是将多个止血带放入一包装盒内，各个止血带之间通过锁扣连接，可以达到连续抽取的目的。
At present, the primary tourniquet is generally made of natural glue, which is wide and flat. Taking strip as a unit, most of them are independent and single packing, which is very inconvenient for nursing staff to use. Before each use, they have to disassemble the packing and use it frequently, which leads to greatly reduced work efficiency and unwilling to use it. The latest lock and draw type disposable tourniquet that has been put on the market is to put multiple tourniquets into a packing box, and the tourniquets are connected with each other through the lock to achieve the purpose of continuous extraction.
