Definitions

  • the utility model relates to a medical device, in particular to an infusion device self-closing device.
  • Infusion sets are one-time consumables that are used in hospitals.
  • patients are infusion, because of the long time, the caregiver or the patient is prone to fatigue.
  • the nurse Once the drug is finished, if the nurse is not promptly notified, the nurse will take the needle.
  • the patient returns blood, causing pain to the patient, the needle is pulled too early, and the residual liquid is too much, which causes waste.
  • the purpose of the utility model is to provide an infusion device self-closing device with simple structure and good sealing effect.
  • the purpose of the utility model can be achieved by the following measures:
  • the utility model comprises a casing, wherein the upper and lower ends of the casing are respectively provided with a liquid inlet and a liquid outlet, and a base with a cavity is arranged in the casing, and a floating body is arranged in the base, an outer surface of the floating body and an inner surface of the cavity in the base In agreement, a liquid outlet is provided in the center of the base.
  • the floating body is a sphere or a cone, etc., and may also be other suitable shapes.
  • the outer casing and the base are cylindrical or other shapes.
  • the outer casing is composed of a cylindrical cavity in the middle and a liquid-passing pipe at the upper and lower ends.
  • the outer casing is formed by a cylindrical cavity in the middle and a liquid-passing pipe at the lower end.
  • the outer casing is composed of upper and lower parts which are assembled together, and of course, it can also be made into an integrated structure.
  • the utility model adopts the design of the floating body and the concave cavity in the base, so that the utility model can effectively solve the problem of drug residue and the blood return problem caused by not taking the needle in time, and has the advantages of simple structure and good effect.
  • the utility model can be applied to other similar functions in addition to medical devices. Aspect.
