Technical Field
The invention relates to the technical field of medical care products, in particular to a central venous catheter tip protection device for hemodialysis.
Background
Hemodialysis, abbreviated as hemodialysis. Hemodialysis is one of kidney replacement treatment modes of patients with acute and chronic renal failure. The blood and electrolyte solution (dialysate) with similar concentration of organism are arranged inside and outside the hollow fiber by draining the blood in vivo to the outside of the body and passing through a dialyzer consisting of a plurality of hollow fibers, and the function of a semipermeable membrane is utilized to exchange substances by dispersion/convection, thereby removing metabolic waste in the body and maintaining the balance of electrolyte and acid-base; at the same time, the excess water in the body is removed, and the whole process of purified blood return is called hemodialysis.
In hemodialysis departments of various hospitals, in order to facilitate unrestricted movement of upper limbs of patients, a fistulization opening is usually formed in the neck of a patient, a central venous catheter for hemodialysis is inserted into the body of the patient so as to communicate with the central vein of the patient, and the end of the inserted central venous catheter for hemodialysis is kept outside the neck of the patient.
For hemodialysis patients, dialysis is generally required to be performed three times a week, namely, dialysis is performed once every other day, the dialysis time length of each time is not more than one day, so that when hemodialysis is not performed on the hemodialysis patients, the hemodialysis central venous catheter tip for retaining the neck of the hemodialysis patients needs to be isolated and protected to avoid bacterial infection of the hemodialysis stoma of the neck of the patients due to contamination of foreign matters, and therefore, the protection of the hemodialysis central venous catheter tip is very important.
At the present stage, when the patient is not subjected to hemodialysis, the hemodialysis central venous catheter tip which is kept at the neck of the patient and the hemodialysis stoma of the neck of the patient are generally wrapped and protected integrally by medical gauze, and the method has certain defects and shortcomings although the method is widely used;
particularly, medical gauze is the hydroscopicity material, and this is not convenient for patient's shower just, in case patient's shower and when spattering corresponding medical gauze with the water stain, can lead to patient's neck hemodialysis fistulization mouth contaminated and lead to the bacterial infection promptly to, the medical gauze that uses exposes also easily to be infected with the dust and is rubbed and lead to being easily contaminated and the pine takes off by patient's upper part of the body clothing, and simultaneously, the medical gauze that uses directly exposes also very unattractive.
