Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
Referring to fig. 1, the iodine solution protective cap comprises a protective cap upper cap 10 and a protective cap lower cap 30, wherein the protective cap upper cap 10 comprises a hollow part with only one open end, the open end 14 of the hollow part is connected with the protective cap lower cap 30, and the hollow part of the protective cap upper cap 10 is a closed space by connecting the protective cap lower cap 30 with the open end 14.
Referring to fig. 1 and 3, a plug 11 is fixedly connected to an inner wall of an upper end (an end far away from an opening end 14) of the upper cover 10 of the protective cap, an annular space 12 is formed between the plug 11 and the inner wall of the upper cover 10 of the protective cap, a sponge 20 is arranged in the annular space 12, a distance is provided between a lower end face of the sponge 20 and a lower end face of the plug 11, the sponge 20 is made of polyurethane, the shape of the sponge is a cylinder or a regular polygon, a circular hole 21 is formed in the middle of the sponge, and the plug 11 penetrates through the circular hole 21. The sponge 20 is adsorbed with disinfectant, which is povidone iodine.
As shown in fig. 1, the lower part of the upper cap 10 is provided with internal threads 13, and the internal threads 13 are used for connecting the upper cap 10 with external threads of a screw port of an external peritoneal dialysis connecting tube.
Referring to fig. 1, in order to facilitate the insertion of the plug 11 into the interior of the spiral port of the external connection tube for peritoneal dialysis, the plug 11 has a tapered shape (such as a luer connector) with a large upper part and a small lower part.
As shown in fig. 1, for sealing safety, the upper surface of the lower cap 30 of the protective cap is fixed with a convex sealing body 31, and the sealing body 31 is located in the open end 14 and is in interference fit with the open end.
To reduce the size of the iodine solution protective cap, the open end 14 abuts the internal thread 13, as shown in fig. 1.
In order to use less material, the plug 11 is hollow tubular, as in fig. 1.
As shown in fig. 2 and 4, in order to increase the friction force, the outer surfaces of the upper cap 10 and the lower cap 30 are provided with friction areas (see reference numerals 101 and 301).
The working principle is as follows:
when not in use, the lower cap 30 is connected to the open end 14 to make the hollow part of the upper cap 10 a closed space, so as to keep the sponge 20 and the disinfectant from contacting the outside.
During the use, take off protective cap lower cover 30, hold the friction district of holding protective cap upper cover 10, aim at peritoneal dialysis external connecting pipe screw port with stopper post 11, carry out threaded connection with the internal thread 13 of protective cap upper cover 10 and peritoneal dialysis external connecting pipe screw port, when revolving wrong, stopper post 11 aims at peritoneal dialysis external connecting pipe screw port gradually and seals, airtight screw interface inner chamber, simultaneously, sponge 20 and the disinfectant in it contact the external connecting pipe screw port of peritoneal dialysis, the sponge that soaks with the disinfectant wraps up external connecting pipe screw interface surface after receiving the extrusion, keep external connecting pipe screw interface disinfection state.
