The outer surface of the disinfection cap 10 and the inner surface of the sheath 9 have vertical stripes that cooperate with each other, and the outer surface of the sheath 9 and the inner surface of the cavity 8 have vertical stripes that cooperate with each other. The split structure is convenient for separating the sheath 9 from the protective cap 5 and storing them separately when the disinfection and protection operation of the infusion port is not required.
使用时，当护士使用注射器完成冲洗、封管操作后，将注射器从输液端口取下，从空腔8取出护套9，将封口贴12撕开。将消毒盖帽10对准输液端口（如正压接头等）按顺时针方向旋拧，将消毒盖帽10固定在输液端口处，然后向后抽离护套9。 When in use, after the nurse uses the syringe to complete flushing and tube sealing operations, the syringe is removed from the infusion port, the sheath 9 is taken out from the cavity 8, and the sealing sticker 12 is torn off. Align the disinfection cap 10 with the infusion port (such as a positive pressure joint, etc.) and twist clockwise, fix the disinfection cap 10 at the infusion port, and then pull the sheath 9 backwards.
实施例3 Example 3
如图5所示，作为另一种优选结构，消毒盖帽10采用硬质塑料时，消毒盖帽10直接存放于空腔8中，用封口贴密封消毒盖帽10，护帽5侧壁在近底部处有两个缺口13，便于将护帽5中的消毒盖帽10推出。消毒盖帽10外表面与空腔8内表面有相互配合的竖条纹。 As shown in Figure 5, as another preferred structure, when the sterilizing cap 10 is made of hard plastic, the sterilizing cap 10 is directly stored in the cavity 8, and the sterilizing cap 10 is sealed with a sealing sticker, and the side wall of the protective cap 5 is near the bottom. There are two gaps 13, which are convenient for the disinfection cap 10 in the protective cap 5 to be released. The outer surface of the disinfection cap 10 and the inner surface of the cavity 8 have vertical stripes that cooperate with each other.
使用时，当护士使用注射器完成冲洗、封管操作后，将注射器从输液端口取下，从空腔8取出消毒盖帽10，将封口贴12撕开。将消毒盖帽10对准输液端口（如正压接头等）按顺时针方向旋拧，将消毒盖帽10固定在输液端口处。 When in use, after the nurse uses the syringe to complete flushing and tube sealing operations, the syringe is removed from the infusion port, the disinfection cap 10 is taken out from the cavity 8, and the sealing sticker 12 is torn off. Align the disinfection cap 10 with the infusion port (such as a positive pressure joint, etc.) and twist clockwise to fix the disinfection cap 10 at the infusion port.
在完成实施例中操作后，消毒盖帽10连同内里的浸有消毒液的海绵11则连接在输液端口处。浸有消毒液的海绵11与输液端口紧密接触，起到对输液端口的消毒保护作用。在护士进行下次冲洗、封管操作时，将消毒盖帽10从输液端口处分离，即可进行冲封管操作。完成操作后继续将消毒盖帽10重新对准输液端口操作，即可完成对端口的保护工作。从上述可知，消毒盖帽的使用使得输液端口消毒操作简单、标准化。 After the operation in the embodiment is completed, the disinfection cap 10 and the sponge 11 soaked in the disinfection solution inside are then connected to the infusion port. The sponge 11 soaked in the disinfectant is in close contact with the infusion port to protect the infusion port from disinfection. When the nurse performs the next flushing and sealing operation, the disinfection cap 10 is separated from the infusion port, and then the flushing and sealing operation can be performed. After completing the operation, continue to align the disinfection cap 10 with the infusion port again to complete the protection of the port. It can be seen from the above that the use of the disinfection cap makes the disinfection operation of the infusion port simple and standardized.
