Description

TECHNICAL FIELD

[0001] The utility model relates to a reinforced arteriovenous fistula hemostasis device belongs to the field of clinical nursing. BACKGROUND

[0002] In clinical nursing work, when the dialysis patient completes the dialysis treatment, the needle is pulled out after the machine. The puncture site often occurs bleeding. Not only increases the workload of the nurse, but also causes the patient to lose blood. Because long-term dialysis patients all have chronic anemia, each dialysis has blood loss. It is our important responsibility to cherish every drop of blood of the dialysis patient.

[0003] The natural blood flow of mature and unobstructed internal fistula is more than 500-600ml / min, so the loss of blood in the human body within a short time exceeds 800ml, which will cause blood pressure to drop and shock. If the blood loss continues or the rescue is not timely, it will endanger life.

[0004] Hemodialysis treatment is an important treatment for patients with renal failure. In the clinical work of the dialysis room, the puncture needle is pulled out of the body after the dialysis patient completes the dialysis treatment. The puncture point needs to be pressed to stop bleeding. The reason for the bleeding is:

[0005] 1. Because the dialysis patient has long-term hemodialysis treatment, the arteriovenous puncture point needle eye is large, the blood flow is fast, and the arteriovenous fistula blood vessel is dilated to form an arteriovenous aneurysm, so that the puncture point is uneven, which causes the pressure fistula ball to be difficult to fix after the needle is pulled out.

[0006] 2. Because the dialysis patient uses anticoagulants for a long time, the clotting time is prolonged.

[0007] 3. Because the patient's arm movement causes the pressure fistula ball to be often displaced from the arteriovenous fistula puncture point, causing the puncture point to bleed. Excessive blood loss can cause the arteriovenous fistula to fail, and even shock.

[0008] The existing pressure fistula ball has the following disadvantages:

[0009] The pressure fistula ball and the puncture point are displaced: the movement of the patient's arm may cause the pressure fistula ball to be displaced from the arteriovenous fistula puncture point, which not only reduces the pressure of the hemostatic ball on the puncture point, but also may cause the puncture point to bleed.

[0010] The hemostatic ball is not fixed firmly: the existing hemostatic ball may be due to design defects, such as too narrow adhesive tape or pressure pulse belt that is not fixed firmly, which causes the hemostatic ball to be not fixed firmly and unable to provide continuous and stable pressure hemostasis.

[0011] Comfort and safety problems: the existing hemostatic ball may not be comfortable enough to cause discomfort to the patient, or may cause allergic reactions due to material problems.

[0012] Cost and operational complexity: Some existing hemostatic balls can be costly or operationally complex, requiring additional training and time, which increases the difficulty and cost of nursing work. Invention content

[0013] To overcome the defects of the prior art, the utility model provides a reinforced arteriovenous fistula hemostatic device, the technical scheme of the utility model is:

[0017] The medical pressure-sensitive adhesive layer is coated on one side of the medical non-woven fabric, which is used to fix the cylindrical compression fistula ball on the skin of the patient;

[0018] The annular groove part is arranged along the circumferential direction of the cylindrical compression fistula ball and is integrally formed with the cylindrical compression fistula ball, which is used to accommodate the puncture point and ensure the close contact between the cylindrical compression fistula ball and the puncture point;

[0019] The anti-skid part is arranged on the outer surface of the cylindrical compression fistula ball close to the annular groove part, which is used to increase the friction with the skin and prevent the cylindrical compression fistula ball from sliding during use.

[0020] It also includes a breathable window arranged on the medical non-woven fabric, which covers the central area of the cylindrical compression fistula ball and is integrally formed with the medical non-woven fabric, which is used for air circulation.

[0021] An indication area is arranged on the edge of the medical non-woven fabric, which is used to guide the nurse to correctly place the hemostatic ball.

[0022] The width of the medical non-woven fabric is consistent with the length of the cylindrical compression fistula ball.

[0023] The medical pressure-sensitive adhesive layer is directly coated on one side of the medical non-woven fabric, which is integrally formed with the medical non-woven fabric, and the other side is exposed to facilitate pasting on the skin.

[0024] The indication area is directly printed or embossed on the edge of the medical non-woven fabric, which is integrally formed with the non-woven fabric.

[0025] The diameter of the cylindrical compression fistula ball is 2cm, and the length is 3cm, which is made of cotton material.

[0026] The medical non-woven fabric has a length of 14 cm and a width of 3 cm.

[0030] Stable fixation: The medical pressure-sensitive adhesive layer ensures that the hemostatic device can be stably fixed on the patient's skin, reducing displacement and falling caused by patient activity, and improving the reliability of hemostasis.

[0031] Precise compression: The design of the annular groove part allows the cylindrical compression ball to accurately accommodate the puncture point, ensuring close contact with the puncture point and improving hemostasis efficiency.

[0032] Anti-slip design: The anti-slip part increases the friction with the skin, effectively preventing the cylindrical compression ball from sliding during use, ensuring continuous and stable compression.

[0033] Improve patient comfort: Due to the anti-slip design and integrated structure, the number of adjustments required due to device movement or falling is reduced, improving patient comfort.

[0034] The utility model reduces the occurrence of puncture point bleeding, making patients more confident and safe. It improves the work efficiency of nurses, and more importantly, reduces the occurrence of nursing adverse events, achieving the safety of dialysis patients. BRIEF DESCRIPTION OF DRAWINGS
