Description
Technical Field
The invention belongs to the technical field of medical treatment, and particularly relates to a PICC pulse type washpipe device for a patient discharged from a hospital.
Background
The PICC is a central venous catheter for puncture through a peripheral vein, is an indwelling catheter method for directly inserting a catheter from the peripheral vein to a superior vena cava, and is generally inserted into any one of a basilic vein, a median elbow vein and a cephalic vein of an elbow pit of a patient; the PICC can avoid direct contact between chemotherapy drugs and arm veins, has high blood flow speed of a large vein (superior vena cava), can quickly flush the chemotherapy drugs, and prevents the drugs from stimulating blood vessels, so that the PICC can effectively protect upper limb veins, reduce phlebitis and relieve pain of patients; the PICC technology is widely applied clinically, and is mainly applied to: patients who need long-term venous transfusion but have poor peripheral superficial vein conditions and are not easy to puncture successfully; patients who need to repeatedly input irritant drugs; patients who need to input high-permeability or high-viscosity medicines for a long time, and the like.
The PICC catheter can be left in a patient body for a long time, but is left in a blood vessel for a long time, blood is reserved in the catheter, the blood in the catheter is easy to coagulate, if the blood in the catheter coagulates, the PICC catheter needs to be pulled out or urokinase is used for thrombolysis treatment, but urokinase thrombolysis needs to be used for thrombolysis, the thrombus cannot be dissolved, if the PICC catheter is pulled out, the patient possibly needs to replace the PICC catheter, and the PICC catheter needs to be placed by about 2000 yuan, so that the PICC catheter is very important for flushing and sealing the catheter; the existing tube sealing method is to add 1.6ml heparin sodium into 100ml normal saline to prepare tube sealing liquid containing 100 units heparin per ml for tube sealing, if the patient catheter has infection risk, the tube sealing liquid can be used for sealing the tube by antibiotics and heparin, one injection of aztreonam is diluted by 0.5g, 2ml heparin and 1ml normal saline to be uniformly mixed and sealed, if the patient has contraindication to heparin, the tube can be flushed by normal saline alone, the tube is flushed by normal saline once by 5-10 ml, and the tube is flushed once every 6-8 hours.
Carry out the flushing to the patient that discharges from hospital PICC troublesome, the patient oneself inconvenient operation, PICC catheter infection leads to patient's general infection easily moreover, and the PICC catheter generally has about 10cm long at external section, and the catheter is drawn and leads to the catheter to drop easily, causes the patient to bleed greatly, seriously influences patient's life health.
