Abstract
A rolling stagnation clamp comprises a clamp body and two wheel-shaped rolling clamping portions placed on two sides of a connecting hose for a remaining needle or an indwelling catheter respectively. Two wheels can be close to each other, so that the connecting hose positioned between the two wheels is occluded and stagnated. After the connecting hose is occluded by the two wheels, the two wheels can oppositely rotate, so that the rolling stagnation clamp shifts on the connecting hose. By the aid of the technical scheme, the rolling stagnation clamp has the advantages that the problem of blood backflow after the connecting hose is occluded and stagnated is solved, and the problem of negative-pressure blood backflow when a connecting hose is occluded in the prior art is also solved.
Description
Technical field:
This utility model relates to a kind ofly imports the intravital apparatus of people with medium, particularly a kind of rolling flow-stopping clip that is used for remaining needle and inlying catheter.
Background technology:
Remaining needle and inlying catheter are widely used clinically, but the blood back plugging phenomenon in remaining needle and the inlying catheter is commonplace.Prior art is oppressed the flexible pipe that is connected of remaining needle and inlying catheter through flow-stopping clip, makes the liquid in pipe fluid stopping.
Chinese patent ZL200720038724.0 discloses a kind of remaining needle with flow-stopping clip, and its fluid stopping mode is the connection flexible pipe that two clamping parts of flow-stopping clip is inwardly compressed remaining needle, realizes fluid stopping.During practical operation, must the action section of flow-stopping clip be crossed the card inner surface that is partially pressed into canned paragraph, the action that this mistake is partially pressed into makes remaining needle connect flexible pipe and is compressed excessively earlier, is discharged by part then, and this just causes the negative pressure blood back of keeping somewhere in the syringe needle.Chinese patent ZL201020300568.2 discloses a kind of remaining needle flow-stop valve, when practical operation, must be with the hands from the both sides of flow-stop valve remaining needle be connected flexible pipe and is squeezed into the fluid stopping seam on the flow-stop valve.In extrusion process, connect flexible pipe and pointed the compressing distortion, be pressed into after fluid stopping is sewn to the position when connecting flexible pipe, hands is released the compressing of flexible pipe, causes the negative pressure blood back of keeping somewhere in the syringe needle.
Prior, prior art only manages to solve the fluid stopping problem, but after can't solving fluid stopping; Blood back problem in the pipe that causes owing to patient cough or multiple reason such as exert oneself; So, after having used flow-stopping clip, keep somewhere the interior blood back of needle tubing and cause the phenomenon of plugging still to happen occasionally clinically.
Summary of the invention:
In order to address the above problem, this utility model provides a kind of flow-stopping clip that simply, effectively rolls.
The technical scheme of this utility model is: a kind of rolling flow-stopping clip; Comprise clamp (7) and two clamping parts that are connected the flexible pipe both sides that place remaining needle or inlying catheter respectively; It is characterized in that: said two clamping parts are wheel-like structure; Said connection flexible pipe (6) is via passing between wheel (1), wheel (2), and wheel (1), wheel (2) close are closed connection flexible pipe (6) folder between two-wheeled.After said two-wheeled will connect flexible pipe (6) folder and close, can rotate in opposite directions, make said rolling flow-stopping clip connect flexible pipe (6) top offset.Said two-wheeled places clamp (7), and clamp (7) is provided with wheel shaft chute (3).Wheel (1), wheel (2) will connect flexible pipe (6) and press from both sides when closing, and wheel axle center (4) is vertical with wheel shaft chute (3) with the line in wheel axle center (5).
The superiority of the technical scheme of this utility model is: said rolling flow-stopping clip provides processing to connect the solution that flexible pipe is pressed from both sides apolipsis stream back blood back, has solved the problem of prior art generation negative pressure blood back when folder closes the connection flexible pipe again.Can rotate in opposite directions after hose clip closes because the two-wheeled of said rolling flow-stopping clip will connect, make the rolling flow-stopping clip connect the flexible pipe top offset, so; After the fluid stopping; When patient owing to cough or multiple reason such as exert oneself, when causing the most advanced and sophisticated blood back of remaining needle or inlying catheter, only need said rolling flow-stopping clip is being connected on the flexible pipe towards the vessel directions displacement; Can blood back be extruded the tip of remaining needle or inlying catheter, thereby effectively reduce the generation of blood back plugging phenomenon in the conduit.Because the line in two-wheeled axle center when the wheel shaft chute on the said rolling flow-stopping clip will connect hose clip and close perpendicular to two-wheeled, make when connecting flexible pipe is closed by folder forces on it not have part and discharge, thereby avoid managing interior negative pressure blood back.
Description of drawings:
Fig. 1 is the structural representation of this utility model rolling flow-stopping clip.
Fig. 2 is that the A of Fig. 1 is to view.
Specific embodiment:
In conjunction with Fig. 1, Fig. 2, a kind of rolling flow-stopping clip when the transfusion administration finishes, will take turns 1 and press down along chute 3, make its bottom land position that places wheel axle center 4, and this hour wheel 1 and wheel 2 press from both sides the flexible pipe 6 that is connected of remaining needle or inlying catheter to close the completion fluid stopping.
After connecting flexible pipe 6 quilt folder apolipsis streams; If patient coughs or firmly causes blood back in remaining needle or the inlying catheter pipe; Only need taking turns 1 or/and take turns 2 application of forces, make the rolling flow-stopping clip, can blood back be extruded the tip of remaining needle or inlying catheter connecting on the flexible pipe 6 towards the vessel directions displacement.
The embodiment of the above is the preferential embodiment of this utility model, under the condition that does not break away from this utility model principle, to shape and the constructional change that said embodiment made, all should fall into the protection domain of this utility model.
Claims (4)
1. rolling flow-stopping clip; Comprise clamp and two clamping parts that are connected the flexible pipe both sides that place remaining needle or inlying catheter respectively; It is characterized in that: said two clamping parts are wheel-like structure; They can be each other near, the remaining needle that will be between two-wheeled or the connection hose clip apolipsis stream of inlying catheter.
2. a kind of rolling flow-stopping clip according to claim 1 is characterized in that: after said two-wheeled will connect hose clip and close, can rotate in opposite directions, make said rolling flow-stopping clip connect the flexible pipe top offset.
