Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical accessories, and particularly relates to a hemodialysis auxiliary nursing device. BACKGROUND

[0002] Hemodialysis is a routine method for treating end-stage kidney disease, which cleans the patient's blood through extracorporeal circulation. This process simulates the function of a healthy kidney, helping to remove excess fluid, electrolytes and waste from the body. Hemodialysis uses a semipermeable membrane for material exchange, which allows small molecules (such as urea, creatinine and other waste and excess water molecules) to pass through, but not large molecules (such as proteins and blood cells). The basic steps of hemodialysis include: first, blood is drawn from the patient's body through an arteriovenous fistula or temporary catheter, then the blood enters the dialyzer (artificial kidney), which contains a semipermeable membrane, and the waste and excess water in the blood pass through the dialysis membrane into the dialysate; during the material exchange process, the dialysate contains components similar to the electrolyte concentration in the blood, and through the concentration gradient, the waste is moved from the blood to the dialysate, while maintaining electrolyte balance, and finally the purified blood is returned to the patient's body through another tube. The process of hemodialysis includes a preparation phase, during which the nurse or technician will clean and prepare the arteriovenous fistula or catheter to ensure that the equipment is sterile; then connect the dialysis circuit, including the hemodialysis machine, dialyzer and blood pump; during the dialysis process, the nurse or technician will regularly check the patient's blood pressure, body temperature and electrolyte levels to ensure everything is normal and adjust the dialysis parameters as needed; after dialysis, the blood is circulated in the dialysis machine to prevent clotting, and then the blood is returned to the patient's body, and after completion, the arteriovenous fistula is fixed or the catheter is removed. Indications mainly include end-stage kidney disease, in addition, acute kidney injury, certain toxic conditions, severe fluid overload and electrolyte imbalance may also use hemodialysis. Common risks and complications include hypotension, muscle spasms, infection, dialysis arrhythmia, blood clotting and malnutrition, etc. In terms of maintenance and management, dialysis is usually performed 2-3 times a week, each time for about 3-5 hours, while limiting potassium, phosphorus, sodium-containing foods, maintaining appropriate protein intake, and controlling daily fluid intake according to urine output, adjusting drug use according to doctor's orders. As an important kidney replacement therapy, hemodialysis plays a crucial role in ensuring the quality of life and prolonging the life of patients, and patients and their family members should work closely with the medical team to understand the dialysis process, manage their diet, control fluid intake and deal with possible complications in order to better cope with the challenges posed by the disease.

[0032] The following effects and novel technologies are brought about:

[0033] Improve the fixing effect: through the combination of the arm ring 41, the bracket 42 and the clamping block 43, the position adjusting structure 4 can effectively fix the patient's arm, prevent accidental shaking during treatment, and ensure the stable operation of dialysis.

[0034] Self-adaptive adjustment: the diameter of the arm ring 41 is adjustable, which can be adjusted according to the thickness of the patient's arm, so as to provide the best fixing effect. For patients of different body types, this self-adaptive adjustment ability enhances the universality and application range of the device.

[0035] Increase flexibility: the user can modify the connection mode between the arm ring 41 and the bracket 42, add rotating connecting parts, make the arm ring 41 be able to flip in the middle of the bracket 42, further improve the use flexibility, and adapt to patients with different arm positions.

[0036] Increase the fixed length: the design also considers the setting of the position adjusting structure 4 inside the lower branch groove 6 and the upper branch groove 8, which increases the length of the patient's arm being clamped, so as to provide more comprehensive fixing.

[0037] Convenient operation: the clamping connection design of the position adjusting structure 4 simplifies the installation process of the clamping block 43, medical staff can quickly adjust the fixed position according to the position of the patient's arm, which reduces the operation time and complexity.
