Description

Single-hand double-cavity syringe for simultaneously sealing pipe

Technical Field

The utility model relates to the field of syringes, in particular to a single-hand double-cavity syringe for simultaneous tube sealing.

Background

The PICC has the advantages of little pain, high safety and easy operation, and has been widely used in clinical practice. The high-pressure resistant catheter is not only suitable for patients who need to inject contrast medium for definite diagnosis and/or disease treatment effect evaluation during multiple times of enhanced CT scanning, but also suitable for patients who need critical care, and can meet the requirements of intravenous therapy, namely, intravenous bolus injection, superposition combined administration chemotherapy, rapid infusion and central venous pressure monitoring, thereby really realizing 'one-needle' type completion of all intravenous therapy. However, there are problems associated with the use of high pressure resistant injectable PICC catheters. Research shows that the incidence rate of the double-cavity high-pressure-resistant injection type PICC is 23%, wherein the incomplete tube blocking rate is 18%, the complete tube blocking rate is 5%, and the tube blocking rate is obviously higher than that of the single-cavity high-pressure-resistant injection type PICC. Research shows that various PICC catheters have blood return in the catheters, which is the main reason for catheter blockage. 2016 American "infusion treatment practice Standard" and the national vein treatment nursing technical operating standard recommend that the catheter occlusion liquid is 0-10U/ml heparin liquid, and at present, in domestic multiple researches, the incidence of PICC catheter occlusion is reduced by increasing the concentration of heparin for catheter occlusion or changing to urokinase catheter occlusion. However, studies have shown that 1% to 3% of patients who use heparin drugs develop heparin-induced thrombocytopenia, and that heparin or urokinase tube sealing in patients with bleeding tendency, cerebral hemorrhage, etc. increases the bleeding risk. When the double-cavity high-pressure resistant injection type PICC is clinically used, a scholars think that the tube cavities which are not frequently used are easy to block the tubes, and suggest to alternately use the two tube cavities. At present, the single-hand single-cavity tube sealing is mostly used clinically, the effect of preventing catheter complications and preventing tube cavity blockage is less, so the tube cavity blockage rate can be reduced by using the single-hand double-cavity tube sealing at the same time, but the single-hand double-cavity tube sealing at the same time needs certain technology and time for a front-line clinical nurse, the clinical execution force and the compliance are lower, and certain difficulty exists in the execution of the alternate use of two tube cavities.
