Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1 and fig. 2, the embodiment discloses a dialysis access protective sleeve, which comprises a protective sleeve 1, wherein the lower part of the protective sleeve 1 is thick, the upper part of the protective sleeve is thin, a cotton-sandwiched adsorption layer 2 is attached to the inner surface of the protective sleeve 1, and the cotton-sandwiched adsorption layer 2 is made of a strong water-absorbing material. During the specific use, the dialysis patient will protect the oversleeve 1 area on the arm of having implemented arteriovenous fistula, then the position of adjustment protection oversleeve 1 makes the thick position in protection oversleeve 1 lower part down, does benefit to like this fixedly, can locally raise the affected limb moreover, prevents the limbs swelling. When a patient has emergent massive hemorrhage and lacks first-aid compression hemostatic articles, the cotton-sandwiched adsorption layer 2 can be used for first aid, hemostasis is performed in a pressing mode, precious time is won for rescuing the patient, and reliable guarantee is provided for treatment of the patient; and the upper part of the protective sleeve 1 is thin, so that the compression hemostasis is convenient to implement.

As shown in fig. 1, in this embodiment, elastic bands 3 are disposed at two ends of the protection sleeve 1. So set up, elastic cord 3 can let protection oversleeve 1 fix on patient's arm more reliably, can not remove easily, really plays the guard action.
