Wheel-clamp combined tube-flushing clamp

Abstract

The invention discloses a wheel-clamp combined tube-flushing clamp, comprising a pressure flushing seat, a support shaft, a pressure wheel, a clamp seat plate, a liquid stop hook, an elastic plate, aliquid stop upper clamp strip, and a liquid stop lower clamp block. An infusion catheter is passed through a through slot and a through hole; when the elastic plate is hooked by the liquid stop hook,the lower end of the liquid stop upper clamp strip and the liquid stop lower clamp block tightly clamp the infusion catheter; when pressuring for tube flushing is performed, the pressure wheel moves along the through slot from the other end of the pressure flushing seat, and the pressure wheel turns to a compressive liquid-stop state from a non-pressure state; after the pressure wheel is continually moved, liquid in the infusion catheter compressed passes through the clamping gap between the liquid stop upper clamp strip and the liquid stop lower clamp block in the infusion catheter. The wheel-clamp combined tube-flushing clamp of the above structural form can prevent blood reflow from occurring after liquid stopping by clamping, allows the pressure wheel to be pushed during indwelling stage to implement tube flushing, and allows blood clotting and blocking to be prevented at any time via multiple repeating.

Description

technical field [0001] The invention relates to a medical device, in particular to a tube flushing and stopper clamp for intravenous indwelling needles. Background technique [0002] Indwelling needles, central venous catheters, etc. must block the liquid flow channel during indwelling. Commonly used clips, one-handed clips, etc., are called stop clips. In the process of closing the stop clip, many factors can cause negative pressure in the catheter. Even a slight negative pressure will cause blood to flow into the cannula of the indwelling needle, which will quickly form a thrombus and block the cannula. For this reason, in recent years, there have been a variety of patents and products of elastic stop clips or positive pressure stop clips, which have a positive effect on preventing the formation of thrombus due to negative pressure when closing the stop clips. However, the general indwelling time ranges from several hours to dozens of hours or even longer. After closing, ...

Problems solved by technology

However, the general indwelling time ranges from several hours to dozens of hours or even longer. After closing, there is residual liquid in the indwelling needle, and the blood will penetrate into the residual liquid in the cannula. After reaching a certain concentration and time, a thrombus will form. plugging sleeve

[0003] For this reason, the routine operation of indwelling needles stipulates that when suspending infusion for indwelling, the tube should be flushed with normal saline, then sealed with anticoagulant, and repeated every 6-8 hours, which will not only increase the workload of nursing but also increase the risk of infection. chance, increased medical costs
