After treatment, a doctor often places a nasobiliary drainage tube for a patient, the nasobiliary drainage tube is equivalent to placing one end of a plastic tube in a bile duct, and the other end of the plastic tube is drained to the outside of the body through duodenum, stomach, oral cavity and nostrils, and the main purpose is to drain bile. Since edema may occur in the lower end of the bile duct including the duodenal papilla opening after the operation is performed in the biliary tract, the edema may cause bile drainage to be unsmooth, and acute cholangitis may occur once the bile drainage is unsmooth. The purpose of placing the nose bile duct is to ensure that bile can flow out when edema exists near an operation wound within a short time after an operation, so that acute cholangitis after the operation can not occur. Still another use is that the patient itself suffers from acute cholangitis, and under this condition, the calculus extraction risk is bigger in the first period, and doctors often also place the nose bile drainage tube in the biliary tract to drain the infected dirty bile out, and the calculus extraction is carried out after the bile is clear or the infection is completely recovered, so the operation is safer, and the recovery of the patient is faster. Therefore, the fixing of the nose bile duct and the negative pressure drainage device becomes an important part in the clinical nursing work.
At present, no connecting device suitable for connecting the nasobiliary duct and the drainage device exists in clinic. The nurse is used after the cut rubber tourniquet is soaked and disinfected when the nasal bile duct and the negative pressure box are connected. Not only can the soaked and disinfected tourniquet not be ensured to reach the standard disinfection level. Still often appear because of the pine of negative pressure drainage box and nose bile duct coupling part takes off, lead to the bile juice to spill over the condition emergence on patient's bed unit and clothing, bring the misery for the patient, also lead to nursing staff can not the accurate record discrepancy, influence patient treatment. Also, the drainage tube is short, so that the nasobiliary tube slips due to traction when a patient turns over, the patient can replace the tube, the economic burden is increased, and the sensitive index of department nursing is also influenced.
