Description
Technical Field
The utility model belongs to the technical field of nursing, and particularly relates to an antibacterial device for absorbing blood oozing of an infusion port.
Background
An implanted intravenous administration system (VIAS), called a Port and a chemotherapy pump (Port) for short, is an intravenous infusion device which is implanted under the skin for relieving the irritation of medicine to the blood vessel of a patient and can be kept in the body for a long time, and is divided into three parts: the puncture needle comprises a non-traumatic needle (butterfly wing needle), a catheter which is placed into a subclavian vein, and an injection seat (port body) which is buried under the skin and connected with an infusion needle, wherein the injection seat is connected with the catheter which is inserted into the subclavian vein to form a long-term vascular access and plays a role similar to a port, so that the puncture needle is called as an 'infusion port', the catheter is punctured and placed into a great vein of a human body such as the subclavian vein and the superior vena cava through the skin by a small operation method, part of the catheter is buried in the subcutaneous tissue, the puncture seat at the other end is left in the subcutaneous tissue of the chest wall and is fixed by suturing, only a small suture wound is seen in the appearance of the skin after the operation, and a protruding round ball can be touched on the body surface of a patient after healing and removing the suture. The common position of the catheter of the transfusion port is the superior vena cava, the blood flow is large, the medicine, nutrient solution and blood products can be quickly diluted, and the vein sclerosis or necrosis caused by the stimulation of the blood vessel can be reduced or avoided. Compared with the common intravenous infusion, the method reduces the chance of hardening the blood vessel and also reduces the pain of repeatedly puncturing the blood vessel because the blood vessel can not be found.
Benefits of the port of infusion: (1) no pipe is exposed on the surface, so that doubtful inquiry disturbance of others is avoided; (2) the bath lotion can be used for bathing after being placed under the skin, and is more convenient for daily life; (3) the probability of infection is small, and the transfusion port is completely buried in the body, so that the transfusion port is not easy to be infected, and the problems of skin itch, red swelling and the like caused by PICC (peripherally inserted central catheter) are avoided; (4) the leakage of the medicine is avoided, and the common tube placement may cause the leakage of the chemotherapy medicine due to the 'needle running' caused by improper posture and overlarge action, stimulate the blood vessel and even cause irreversible injury. In this respect, the port has great advantages, which are substantially impossible; (5) the puncture needle can be repeatedly used for a long time, the 19G atraumatic puncture needle punctures 1000 times, the butterfly wing needle is continuously used for 7 days for calculation, and the transfusion port can be used for 19 years, but one transfusion port can also be repeatedly used for more than 10 years according to clinical use experience due to different maintenance modes of each person.
The use of the transfusion port needs to be matched with a nondestructive needle for puncture to establish a venous transfusion channel, the transfusion port base needs to be fixed and the puncture partition needs to be palpated and positioned in the puncture process, generally, a thumb, a forefinger and a middle finger of a non-dominant hand are made into a triangle, the transfusion port is fixed, the middle points of the three fingers are determined, the puncture partition is vertically inserted from the middle point of the transfusion port gently and reaches the bottom of a liquid storage tank, and the transfusion safety and smoothness are guaranteed. However, in clinical use, because patients use different types of transfusion ports and have different skin thicknesses of port placement parts and port seats, the transfusion ports are used in a short time after the port placement, blood and liquid are easy to seep at the wounds of the capsular bags, and the pain of the patients is obvious. In addition, because the operation methods and the proficiency of nurses are different, the transfusion port cannot be well fixed during puncture, the puncture success rate of the transfusion port is reduced, the problems that the medication of patients is influenced, the puncture times and the blockage of catheters are increased and the like are caused, and the pain of the patients and the medical care risk are increased.
