Description

TECHNICAL FIELD

[0001] The application belongs to medical auxiliary equipment, and particularly relates to a hemodialysis catheter protective sleeve. BACKGROUND

[0002] During hemodialysis, waterproof measures for deep vein catheters are very important, and the following are some key waterproof measures: 1. Waterproof dressing is used: when bathing or washing, waterproof paste should be used to protect the puncture point to avoid the catheter being wet or immersed in water. 2. Keep clean and dry: the catheter dressing is replaced every time of dialysis, and the dressing is kept clean and dry. If the patient's skin has symptoms such as itching and redness, the doctor should be consulted in time. 3. Avoid the catheter from contacting water: when bathing, special attention should be paid to protect the catheter to avoid the catheter from contacting water to reduce the risk of infection. 4. Correct catheter care: after dialysis, the catheter should be cared immediately. The catheter port is disinfected with iodophor disinfectant, and is naturally dried. The catheter should not be used as a transfusion line such as infusion and blood transfusion to avoid pollution. 5. Inform the patient of precautions: medical staff should inform the catheterized patient to pay attention to protecting the catheter when bathing or washing to avoid the catheter being wet or immersed in water. 6. Regularly replace the dressing: the dressing covering the puncture point is regularly replaced. The sterile gauze is replaced at least once every 2 days, and the sterile transparent dressing is replaced at least once every week. The dressing should be replaced in time when it is wet, loose or visible pollution. 7. Hand hygiene: medical staff should strictly perform hand hygiene according to the relevant requirements of the Hand Hygiene Standard for Medical Staff before contacting the puncture point of the catheter or replacing the dressing.

[0003] The hemodialysis treatment time is 4 hours each time, and it is inevitable to change the body position, have a meal or sleep. If the limb of the puncture part is suddenly bent, the puncture needle is easily to pierce the blood vessel, form subcutaneous hematoma and cause pain at the puncture part. The puncture needle is also easily to be displaced out of the blood vessel due to turning over, suddenly sitting up, and the pulling and compression of the quilt, which causes the occurrence of internal fistula complications such as insufficient blood flow, bleeding, pain at the puncture part and the like. The serious bleeding can endanger life. Therefore, the patient is very nervous during the 4-hour hemodialysis treatment process, and the medical staff is not convenient when observing and treating. SUMMARY

[0004] The purpose of the present application is to provide a hemodialysis catheter protective sleeve, which comprises a shell, the edge of the shell is hard, the upper and lower parts of the shell are hard parts of the shell for fixing the catheter, the middle part of the shell is made of transparent material to facilitate the observation of the internal blood vessel, a protective film is arranged on the inner surface of the shell, a buckle is arranged on one side of the shell, a pipe hole is left in the hard part of the upper end of the shell, two pipe holes are left in the hard part of the lower end of the shell, one side of the outer surface of the shell is a skin-adhesive surface, and the skin-adhesive surface has adhesion to be attached to the skin.

[0005] Further, the protective film is a PE self-adhesive protective film, which wraps the catheter and is adhered when the shell is closed, so as to prevent water or dirt from entering.

[0006] Further, an easy-to-tear opening is arranged in the middle of the shell above the protective film, which is used for adjusting the internal catheter when necessary.

[0007] Further, sterilized short fibers are arranged in the inner side of the tube hole, and a water-color-changing material is attached to the short fibers, so that water entering can be observed.

[0008] Further, the transparent part in the middle of the shell is in an integrated structure with the hard part of the shell.

[0009] Further, the shell is made of waterproof material.

[0010] Further, for further fixation, medical staff can use adhesive tape to reinforce and paste on the required position of the patient.

[0011] Compared with the prior art, the hemodialysis catheter joint protection assembly adopting the technical scheme has the following beneficial effects: first, the hemodialysis catheter joint protection assembly of the utility model is used, a nurse puts a protective sleeve on a hemodialysis catheter joint, and the protective sleeve is attached to the skin around the puncture position of a patient, so that the whole hemodialysis catheter joint is sealed in the protective sleeve and can be further reinforced through a fixed patch, so as to prevent the protective sleeve from falling off and causing the hemodialysis catheter joint to be directly exposed and infected, and the hemodialysis catheter joint is sealed and fixed. Second, the protective sleeve is made of waterproof material, the protective film in the protective sleeve further seals and protects the catheter, the hemodialysis catheter joint is sealed in the protective sleeve, and the hemodialysis catheter joint can be prevented from being accidentally wetted by water when the patient uses water. Third, an easy-to-tear opening is arranged on the shell, so that a nurse can make slight adjustment when the hemodialysis catheter joint needs to be adjusted. Fourth, compared with manually wrapping the hemodialysis catheter joint, a nurse puts the hemodialysis catheter joint in the protective sleeve, which saves time and effort and reduces the working intensity of the nurse; the tube holes are arranged on the upper and lower shells, which do not limit the use time and scene. Fifth, sterilized short fibers are arranged in the inner side of the tube hole, so that water entering can be directly observed. BRIEF DESCRIPTION OF DRAWINGS
