A picc pulse flushing device for discharged patients

Abstract

The PICC pulse flushing device for discharged patients includes a bottom plate, tethers are connected to the edges on both sides of the bottom plate, an installation shell is connected to the upper side of the bottom plate coaxially, and a semi-cylindrical notch is horizontally opened on the lower side of the install There is a liquid storage tank, which is connected to the installation shell through a buckle, and the top pressure device is installed on the lower part of the installation shell, and the outer circumference of the lower part of the installation shell is covered with a collar, and the inner ring of the collar is provided with a placement groove along the circumferential direction , the outer ring wall of the collar is provided with penetration holes, the outer circumference of the middle part of the installation shell is connected with a fixed ring through threads, the top surface of the installation shell is provided with a switch and a reverse start button, and the top of the installation shell is installed with a micro-control unit and a battery. , switch, and reverse start button are all connected to the circuit of the micro-control unit; in summary, the invention can effectively help discharged patients to flush the PICC catheter, and can prevent the PICC catheter exposed outside the patient's body from slipping.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a PICC pulse flushing device for discharged patients. Background technique [0002] PICC refers to peripherally punctured central venous catheterization, which is a method of indwelling catheters directly inserted into the superior vena cava from the peripheral veins, usually in the basilic vein, median cubital vein and cephalic vein of the patient Choose one for intubation; PICC can avoid direct contact between chemotherapy drugs and arm veins, and the blood flow in the large vein (superior vena cava) is fast, which can quickly dilute chemotherapy drugs and prevent drugs from stimulating blood vessels, so it can effectively protect Upper extremity veins can reduce the occurrence of phlebitis and reduce the pain of patients; PICC technology is widely used clinically, mainly for: patients who need long-term intravenous infusion, but peripheral superficial vein conditi...

AI Technical Summary

Problems solved by technology

[0003] The PICC catheter can be left in the patient's body for a long time, but if it is left in the blood vessel for a long time, there will be blood in the catheter, and 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 thrombolysis with urokinase However, thrombolysis with urokinase will cost a lot of money, and it may not be able to dissolve the thrombus. If the PICC catheter is removed, the patient may need to re-place the PICC catheter. It will cost about 2,000 yuan to place a PICC catheter, so the PICC catheter needs to be flushed. Tube and tube locking are very important; the existing tube locking method is to add 1.6ml of heparin sodium to 100ml of normal saline to make a tube locking solution containing 100 units of heparin per ml for tube locking. If the patient’s catheter has a risk of infection, antibiotics can be used+ Heparin sealed tube, aztreonam for injection 0.5g + 2ml heparin + 1ml normal saline is diluted and mixed evenly to seal the tube, if the patient has contraindications to heparin, the tube can be flushed with normal saline alone, and the normal saline can be flushed once 5-10ml , flush the tube every 6-8 hours

[0004] It is troublesome to flush the PICC for discharged patients, and it is inconvenient for the patient to operate, and the infection of the PICC catheter can easily lead to systemic infection of the patient. The length of the PICC catheter is generally about 10 cm outside the body, and the catheter is easily pulled off, causing the patient to hemorrhage. Seriously affect the life and health of patients
