Description

Novel hemodialysis is pressed with blood vessel and is stanched device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to novel hemodialysis is with vascular pressing hemostasis device.

Background

The maintenance hemodialysis is one of the treatment means of the end-stage renal disease, and the good vascular access is the basis for ensuring the smooth proceeding of the hemodialysis and is the 'life line' of the patient with the maintenance hemodialysis. Autologous arteriovenous internal fistula (AVF) is the first vascular access of a maintenance hemodialysis patient, the first 5-10 puncture periods are the start-up periods of early internal fistula, the start-up period is the internal fistula blood vessel: the wall is thin, the brittleness is large, the elasticity is poor, the pressure is high, the puncture needle eye is easy to damage and not easy to heal; artificial vascular graft internal fistulas (AVGs) are valuable vascular access for maintenance hemodialysis patients, internal fistula vessels in use: the blood vessels are different in depth, bent during running, free of reparative property, inferior in elasticity and contractibility to autologous blood vessels, and form blood coagulation plaques after needle withdrawal to stop bleeding. During the starting period, AVF and AVG are improperly pressed after needle withdrawal, bleeding and subcutaneous hematoma are easy to occur, pain of patients is increased, serious patients can cause thrombus, mature development and service life of internal fistula are directly affected, the best pressing method is that a senior special nurse directly presses fingers to accurately press two puncture points of a skin-entering needle eye and a blood vessel-entering needle eye without blocking blood backflow of the far end of a limb, but the labor cost of the nurse which needs to consume is higher. In 2020, 6 new fistulas are started in the department of China, each fistula takes 450 minutes in total and is calculated according to the first 5 times of puncture, each time of puncture is at least 15 minutes; artificial arteriovenous fistula (AVG) 11 persons punctured 32 times per week 1664 times per year with at least 5 minutes per compression for a total time of 8320 minutes. Fistulae and AVG direct finger pressure during the start-up period: the total time consumption is 8770 minutes (146.2 hours) every year, which is equivalent to that at least 18.27 working days of special nurses with advanced skills are consumed every year to reduce the incidence rate of the internal fistula and the AVG subcutaneous hematoma in the starting period, maintain the patency rate of the internal fistula and prolong the service life of the internal fistula.

At present, the clinical hemostasis method after needle withdrawal comprises the following steps:

1. binding of hemostatic bandage to stop bleeding: is a method generally used in clinic at present, and is simple and quick. Checking the puncture point position when dialysis is finished, folding (7 cm multiplied by 9 cm) sterile gauze into a cuboid of 2x3cm, placing the cuboid above the skin of the puncture point, pressing the upper side of the sterile gauze by using an index finger and a middle finger while pulling out the puncture needle, then binding and pressurizing the tourniquet by using the tourniquet, and gradually relaxing the tourniquet when a patient leaves the hospital. This method is applicable to conventional AVFs, if AVG and AVF enable periods use this method: the tourniquet annular binding pressurization can block the blood supply of the limb end, influence the venous return, cause the limb swelling at the side of the internal fistula and is difficult to be distinguished from subcutaneous hematoma; the degree and time of pressing is not easy to be controlled, which is easy to cause subcutaneous hematoma, artificial blood vessel collapse and internal fistula embolism.

2. Direct finger pressure hemostasis method: because the pressing is accurate, the special nurse of the profession observes the condition of the puncture position at any time, does not block the blood supply of the limb end, influences the venous return, is suitable for the hemostasis by compression of the internal fistula in the AVG and AVF starting period. Checking the puncture point position when dialysis is finished, folding (7 cm multiplied by 9 cm) sterile gauze into a cuboid of 2x3cm, placing the cuboid above the skin of the puncture point, and pressing the top of the sterile gauze with an index finger and a middle finger while pulling out the puncture needle; and the other nurse pulls out the venous end puncture needle, and the off-hook nurse simultaneously presses the index finger and the middle finger of the left hand and the right hand respectively to stop bleeding, wherein the average pressing time is 15-20 min. The method has the defects of insufficient manpower resources for nurses, and the smoothness of the internal fistula cannot be judged in time in the process of pressing by hands of the nurses; if the puncture point bleeds in the pressing process, other nurses need to help to treat the puncture point. The method increases the risk of complications of internal fistula of patients, increases the workload of nurses, and consumes a large amount of labor cost.

3. Novel practical tourniquet stanchs: the air bag is adopted to pressurize and stop bleeding, after dialysis, gauze is placed in the air bag and is placed above a puncture point, and the air bag is pressurized while a needle is pulled out, so that the aim of stopping bleeding is fulfilled. Although the method reduces the workload of nurses, the risk of complications of internal fistula of patients is increased, the pressure in the air bag can not reach the pressure hemostasis force in time when the needle is pulled out, and the internal fistula is easy to bleed and hematoma during the period; the pressure in the air bag can also block the blood supply of the limb end, and the venous reflux is influenced, so that the ischemia, swelling and pain of the limbs at the side of the internal fistula, the collapse of the artificial blood vessel and the embolism of the internal fistula are caused; the hemostatic part pressed by the air bag is not easy to observe, if the bleeding and the displacement of the pressing point occur, the air bag needs to be deflated to be reprocessed and repressed; the air bag compression tourniquet is used for disinfecting the tourniquet which is difficult to meet the requirement of feeling control.
