Description

  The present invention relates to a fixed cover for a puncture needle unit that can satisfactorily prevent a puncture needle stuck in an arm during artificial dialysis, infusion, blood transfusion, blood donation, or the like.

  During infusion or artificial dialysis, it is necessary to keep the injection needle stuck in the arm for a long time during the treatment. For example, the injection needle is fixed with a medical adhesive tape. However, the patient may accidentally drop the needle when the patient moves, or in the case of a patient with dementia or a child, etc. A method is adopted in which the needle tip is fixed so that the needle is not easily removed from the arm. Conventionally, as a method for fixing an injection needle or the like, for example, an injection needle is temporarily fixed to a patient's body with a medical adhesive tape, and injection is performed together with an arm using a medical cinema used for fixing a fracture or a sprain location. The needle was covered and fixed. However, with the conventional method of covering the injection needle with the arm using a cine, the covered part is stuffy and causes skin abnormalities such as itchiness, and the periphery of the arm is fixed to largely suppress movement. Therefore, the patient felt uncomfortable, uncomfortable, a sense of pressure and restraint, or pain and distress, and was physically and mentally burdensome. In addition, since it takes time to attach and detach, and the surroundings of the arm where the needle is inserted cannot be seen from the outside, check the drip and dialysis circuit tube, check the progress and instrument status, and check whether the needle has been removed. When doctors or nurses perform confirmation work such as confirmation or confirmation of the surrounding skin with a needle, etc., it is necessary to remove cine and gauze each time, which is cumbersome and further burdens the patient. It was.

  On the other hand, for example, Patent Document 1 proposes an infusion protector for the purpose of preventing withdrawal of an infusion needle for elderly people, children, and patients with dementia. The drip protector of Patent Document 1 has a mesh-like protective member, a protective frame is provided on four sides of the protective member, and attachment strings are provided on extensions of two opposite sides of the protective frame, and Each attachment string and the protective frame were detachably joined with a hook-and-loop fastener.
