Abstract

The utility model relates to a tube-blockage-preventing stagnation clamp for an indwelling needle. The tube-blockage-preventing stagnation clamp is a clamp formed by bending and folding a rectangular sheet and provided with an upper clamping piece and a lower clamping piece. The sheet is provided with an extension tube hole, and clamping fasteners are correspondingly arranged at the two ends of the sheet. The tube-blockage-preventing stagnation clamp is simple in structure, can generate enough positive pressure and prevent tube blockage, and is convenient to operate. In the process of tube sealing, the complex technique of pushing and retreating is not adopted, an injector does not need to be used for drawing return blood when infusion is carried out again, and whether tube blockage occurs can be judged by observing the blood return condition directly.

Description

Remaining needle pipe-blocking-proof flow-stopping clip

Technical field

This utility model relates to a kind of remaining needle pipe-blocking-proof flow-stopping clip, belongs to armarium technical field.

Background technology

Hospital, to patient infusion, is often used remaining needle.Remaining needle is a kind of disposable use Special medical equipment, and it is mainly comprised of extension tube, extension tube fore-end, extension tube rear end part, flow-stopping clip, and flow-stopping clip is arranged in extension tube.After having infused, with flow-stopping clip, clamp extension tube and cause plugging to prevent negative pressure blood back.

At present, the fluid stopping of generally using accompanies single piece clip, and it is that a diminishing crack is set at the middle part of a plastics monolithic, during use, with the hands operates extension tube is pushed to flow-stopping clip crack, by the folder power of crack, cuts off blood back.The advantage of single piece clip is simple in structure, low cost, but because the place of clamp is a point, malleation weak effect, while causing tube sealing, need adopt the complicated maneuver of moving back while pushing away, misoperation can cause that negative pressure blood back causes plugging or tube-sealing solution to overflow, and easily causes medical personnel to infect.And while using, need bimanualness (both hands pull out, finger tip pressurization), misoperation can cause negative pressure blood back, causes plugging.In addition, while again infusing, need draw back blood with syringe, determine whether plugging.

Summary of the invention

It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and can produce the remaining needle pipe-blocking-proof flow-stopping clip of enough malleations.

The object of the present invention is achieved like this: a kind of remaining needle pipe-blocking-proof flow-stopping clip, is folded to form the clip with upper and lower holding piece by a rectangle wafer warpage; On thin slice, arrange one and extend pore; At the corresponding clip that is provided with in the two ends of thin slice.Flow-stopping clip is arranged in extension tube by extending pore, with hands, two holding pieces is closed up, by dog down, an elongated segment pipe clamp can be lived and fluid stopping.

The further technical scheme of this utility model is: a kind of remaining needle pipe-blocking-proof flow-stopping clip, is folded to form the clip with upper and lower holding piece by a rectangle wafer warpage; Crooked position at thin slice arranges a prolongation pore; In the thin slice one side of clamping extension tube, be provided with one deck flexible glue layer; At the corresponding clip that is provided with in the two ends of thin slice.

Flow-stopping clip is arranged in extension tube by extending pore, with hands, two holding pieces is closed up, by clip, clamped, an elongated segment pipe clamp can be lived and fluid stopping.Because holding piece is provided with one deck flexible glue layer, make fluid stopping better effects if.

Clip of the present utility model is double buckle.Simple in structure, easy to operate.

This utility model is when clinical practice, due to one section (part) of remaining needle extension tube clamped, can produce enough malleations, effectively reduce the generation of plugging phenomenon, and simple to operate, during tube sealing, need not adopt the complicated maneuver of moving back while pushing away, while again infusing, do not need to draw back blood with syringe, directly can observe blood back situation, judge whether plugging.

Accompanying drawing explanation

Fig. 1 is this utility model using state schematic diagram;

Fig. 2 is Fig. 1 deployed condition schematic diagram.

In figure: 1, lower holding piece; 2, upper holding piece; 3, clip; 4, extend pore; 5, flexible glue layer; 6, extension tube.

The specific embodiment

As shown in Fig. 1 Fig. 2, this utility model is comprised of lower holding piece 1, upper holding piece 2, clip 3, prolongation pore 4, flexible glue layer 5.Lower holding piece 1 and upper holding piece 2 are rectangle thin slice; Flexible glue layer 5 is fixedly installed on two holding pieces; Extending pore 4 is arranged between two holding pieces; End face at holding piece arranges primary and secondary clip.This utility model is through in remaining needle extension tube by extending pore 4.During clinical practice, with hands, upper and lower holding piece is fastened on clip, make holding piece clamp a certain section of extension tube and get final product fluid stopping.Simple to operation, fluid stopping is effective.

Claims

1. a remaining needle pipe-blocking-proof flow-stopping clip, is characterized in that: by a rectangle wafer warpage, be folded to form the clip with upper and lower holding piece; On thin slice, arrange one and extend pore; At the corresponding clip that is provided with in the two ends of thin slice.

2. remaining needle pipe-blocking-proof flow-stopping clip according to claim 1, is characterized in that: in the thin slice one side of clamping extension tube, be provided with one deck flexible glue layer.
