Safety and Effectiveness of CATHTONG™ II PICC

Study Overview
=================
Brief Summary
-----------------
This clinical trial is a prospective, multi-centre, open, parallel and comparative non-inferior trial design.

Detailed Description
-----------------
Four clinical trial institutions that meet the national qualification are selected as clinical research centers. After informed consent of the subjects and meeting the selection criteria, the subjects will be included in this clinical study. After the follow-up, all the data were sorted out and analyzed. Finally, the data of the two groups were compared to prove whether the high-pressure-resistant peripherally inserted central venous catheter developed by L&Z US, Inc. was not inferior to the control group.

Age 18 years old, 80 years old; gender is not limited; Suitable for patients who need central venous catheterization via peripheral venipuncture (life expectancy is more than 6 months): need medium-term and long-term infusion or intravenous drug therapy; need multi-chamber infusion of multiple drugs at the same time; need infusion of irritating, corrosive or hyperosmotic drugs; hyperbaric angiography or central venous pressure monitoring function; Patients who need to be maintained in the investigator's hospital after PICC catheterization; Ability to communicate well with researchers and comply with test requirements. Exclusion Criteria: Local infection of puncture vein or occlusion or serious lesion of blood vessel at puncture place; Patients with known or suspected allergies to polyurethane; Pre-intubation site includes trauma history, vascular surgery history, thrombosis history, radiotherapy history, bilateral breast cancer surgery affected upper limbs, superior vena cava compression syndrome, etc. The prothrombin time was 6 seconds longer than the normal value and the activated partial thromboplastin time was 2.5 times longer than the normal value. Pregnancy and lactation women; The subjects had a history of difficulty in catheterization.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Successful rate of one-time catheterization | Subcutaneous detection of blood vessel movements less than three times, and finally completed catheterization and confirmed that the end of the catheter in the pre-positioning proportion of the total number of patients (catheterization success refers to the chest X-ray and other fluoroscopy means to confirm that the end of the catheter is located in the middle and lower segment of superior vena cava). | Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Operating time | The time between the beginning of disinfection of the patient's skin and the fixing of transparent dressing is in minutes. | Day 1 | 
| success rate of one puncture. | Success of one puncture refers to entering the target vein only once. If the puncture needle failed to penetrate the vein once and retreated to the subcutaneous area, then exploratory puncture was the second puncture. | Day 1 | 
| The incidence of adverse events | Record the adverse events in the test, determine whether they are related to the test product, and calculate the incidence of adverse events/reactions. | about three months |
