Description

Neck catheter fixing device for hemodialysis

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a neck catheter fixing device for hemodialysis.

Background

Chronic Kidney Disease (CKD) has become another important Disease threatening human health following cardiovascular diseases, tumors, diabetes. The prevalence rate of chronic kidney diseases in China is as high as 10.8%, 1% of patients can develop End-Stage Renal Disease (ESRD), newly-discovered ESRD patients account for one ten-thousandth of the total number of ESRD patients in China every year, and about 200 ten thousand ESRD patients exist in China according to statistics. Hemodialysis is one of the effective renal replacement therapies for ESRD patients. Good vascular access is a prerequisite to ensure that hemodialysis is performed smoothly and that dialysis is adequate. The establishment and maintenance of a well-functioning vascular access is critical to the success of dialysis. The vascular access of a dialysis patient is often considered the "life line" of the dialysis patient. An ideal vascular access should have: long service life, enough blood flow and few complications. Common vascular access comprises arteriovenous internal fistula (AVF) and a central venous indwelling catheter (CVC), and the proportion of temporary central venous catheters in the neck is up to 91.79% in patients who are clinically dialyzed for the first time at present.

After the temporary blood permeable catheter for the internal jugular vein is successfully placed, the proper fixation of the catheter is emphasized, and if the catheter is not fixed properly, complications related to the catheter, such as catheter breakage, catheter blockage, catheter related infection, skin infection, catheter slippage and the like, can occur. At present, most of clinical methods adopt a traditional adhesive tape fixing method, but the factors influencing the fixation are more, and the temporary blood permeable catheter placement patient in the internal jugular vein is easy to sweat due to more grease secretion of the skin of the neck and the head and face, more wrinkles of the skin of the neck and the like, so that the adhesive tape is easy to be sticky and loose, and gauze wrapping and winding the catheter falls off to expose a puncture point, so that a nurse needs to replace the dressing again, the medical cost and the time cost are increased, and the workload of the nurse is additionally increased; because the neck of a human body has large movement range, under the repeated traction, the suture line used for fixing the catheter at the skin end of a patient is easy to break to cause the catheter to shift or slip, so that adverse nursing events are caused, and the hidden danger of nursing risks is an important factor causing medical disputes; because the existing medical adhesive tape respectively adopts the zinc oxide adhesive and the medical pressure-sensitive adhesive as the manufacturing methods for sticking the skin, the zinc oxide adhesive and the medical pressure-sensitive adhesive can cause discomfort such as skin allergy, red swelling, skin injury, local pruritus and the like of a patient after contacting the skin for a long time; when the adhesive plaster is used for fixing, because the side end of the catheter head is heavy, the phenomenon of over-tension often occurs when the adhesive plaster is used for tightly fixing the cheek parts. Meanwhile, the adhesive plaster has high skin tension on the neck and the head and the face, so that the patient is easy to feel uncomfortable, and skin damage is easy to occur when the adhesive plaster is pulled by high skin tension; and the adhesive plaster has an unfirm fixed appearance and is not attractive, so that patients are easy to generate negative emotions such as depression due to poor psychological experience, and the treatment and prognosis are not facilitated.
