Description
Technical field:
The present invention relates to a kind of medical instrument, particularly relate to a kind of iodide-containing cap for closed peritoneal dialysis external short tube mouth.
Technical background:
After iodide-containing cap is used for peritoneal dialysis treatment, close and sterilization peritoneal dialysis external short tube mouth.CN201453819U discloses a kind of iodide-containing cap, it is characterized in that the port of iodide-containing cap has connection cap to coordinate with it, current iodide-containing cap comprises at the bottom of iodide-containing cap and iodide-containing cap wall, at the bottom of iodide-containing cap and iodide-containing cap wall surround cup-shaped cavity, sponge is filled with in cavity, sponge contains disinfectant solution (povidone iodine), not enough below current technical scheme:
1, peritoneal dialysis external short tube joint is coniform, when povidone iodine cap is on peritoneal dialysis external short tube, the cup-shaped cavity that peritoneal dialysis external short tube joint inserts at the bottom of iodide-containing cap and iodide-containing cap wall surrounds, this external short tube will inevitably form extruding to sponge, disinfectant solution (povidone iodine) contained in sponge just can pass through, into peritoneal dialysis external short tube abdominal cavity, to strengthen the stimulation to abdominal cavity;
2, due to, when povidone iodine cap is on peritoneal dialysis external short tube, povidone iodine cap and peritoneal dialysis connect closely with being formed between external short tube, there is no space, disinfectant solution in sponge is by Quick squeezing, iodide-containing cap loses the protection of disinfectant solution, prevent the effect of bacteriovirus infection from will weaken, and, in extrusion process, there is larger deformation in sponge, when turning on iodide-containing cap, sponge easily comes off from iodide-containing cap, and extruded for a long time due to sponge, cannot reply, the ability absorbing disinfectant solution (povidone iodine) declines, can not reuse, so, current iodide-containing cap can only use once, this not only causes waste, also result in the pollution to environment simultaneously.
Summary of the invention:
The object of the invention is to, provide a kind of, when povidone iodine cap is on peritoneal dialysis external short tube, disinfectant solution can not flow into abdominal cavity, and the good reused iodide-containing cap of Disinfection Effect.
In order to complete object of the present invention, the present invention by the following technical solutions:
A kind of iodide-containing cap comprises at the bottom of iodide-containing cap and iodide-containing cap wall, at the bottom of iodide-containing cap and iodide-containing cap wall surround cup-shaped cavity, wherein, there are one and the tight-lipped leakproof fit iodide-containing cap projection of peritoneal dialysis external short tube in central authorities at the bottom of iodide-containing cap, iodide-containing cap wall is made up of iodide-containing cap wall epimere and iodide-containing cap wall hypomere, water-absorbing flexible material is filled with between iodide-containing cap projection and iodide-containing cap wall epimere, containing disinfectant solution in water-absorbing flexible material, peritoneal dialysis is truncated cone shape with external short tube joint, the shape of iodide-containing cap wall hypomere matches with it, screw thread is had inside iodide-containing cap wall hypomere, the external screw thread of this screw thread and peritoneal dialysis external short tube joint matches, make peritoneal dialysis external short tube joint can be screwed into iodide-containing cap wall hypomere, tightening structure is provided with between iodide-containing cap wall epimere and iodide-containing cap wall hypomere.
