Reference numerals: the blood disinfection device comprises an inner cover 1, external threads 11, a disinfection liquid storage medium 12, a sealing plug 13, an outer cover 2, a shell 21, an elastic filler 22, a disinfection liquid storage layer 23, a threaded wall 24, internal threads 241, a gap 242, a sealing ring 3 and a hemodialysis catheter 4.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Example 1

Fig. 1-3 show a hemodialysis catheter iodine solution microcap according to a preferred embodiment of the present invention, which comprises an inner cap 1 and two outer caps 2, the outer caps 2 covering the inner cap 1 from both ends, respectively.

The outer side wall of the inner cover 1 is provided with an external thread 11, preferably, the middle of the inner cover 1 is provided with a needle hole, a disinfectant storage medium 12 is arranged in the needle hole, and the disinfectant storage medium 12 is preferably medical sponge or medical cotton containing iodophor or alcohol. The two ends of the needle hole are provided with sealing plugs 13.

The outer cover 2 comprises a shell 21, an elastic filler 22, a disinfectant storage layer 23 and a threaded wall 24 which are sequentially embedded from outside to inside. As shown in fig. 4, the screw wall 24 has an internal thread 241 capable of engaging with the external thread 11 of the inner cap 1, and the screw wall 24 has elasticity and a gap 242 is provided on the surface thereof as a seepage passage for the sterilizing liquid.

Preferably, the disinfectant storage layer 23 is medical sponge or medical cotton containing iodophor or alcohol.

Preferably, the resilient filler 22 is foam, rubber or silicone.

Preferably, when the inner cap 1 is covered, the cap openings of the two outer caps 2 are butted and kept sealed, and the cap opening of one outer cap 2 is jointed with the sealing ring 3.

Fig. 1 and fig. 3 show the utility model discloses hemodialysis pipe iodine solution miniature lid's for use state, inner cup 1 and two enclosing covers 2 are fixed together, constitute confined structure, can prevent that the inside antiseptic solution of three for example iodophor, alcohol etc. from being influenced by external air, both can avoid volatilizing, can avoid again being polluted by the external world, and then improve the storage nature of hemodialysis pipe iodine solution miniature lid.

And figure 5 shows the utility model discloses a user state of hemodialysis pipe iodine liquid microcap, wherein two enclosing covers 2 cup joint on two joints of the hemodialysis pipe 4 of Y type, and inner cup 1 overlaps on the syringe needle of the other end, disinfects joint and syringe needle simultaneously to guarantee that the patient is safer when carrying out hemodialysis.

Specifically, when the outer cap 2 covers the joint of the hemodialysis catheter 4, the outer diameter of the joint is designed to be slightly larger than the inner diameter of the outer cap 2, so that the joint can extrude the structure inside the outer cap 2, then, because the elastic filler 22 on the periphery of the disinfectant storage layer 23 has an elastic function and can generate certain elastic force when being extruded by external force, when the joint extrudes the outer cap 2, the elastic filler 22 can be extruded with the disinfectant storage layer 23 as a medium and mutually extrude the joint, and disinfectant in the disinfectant storage layer 23, such as iodophor or alcohol, can seep through the gap 242 of the thread wall 24 and then be coated on the periphery of the joint, so as to achieve the effect of disinfecting the joint.
