Description
Technical field
This utility model relates to a kind of remaining needle, belongs to technical field of medical instruments.
Background technology
Existing remaining needle generally comprises indwelling flexible pipe, indwelling needle, prolongation base, is connected to indwelling needle and extends prolongation flexible pipe between base, is installed on the liquid stopping clamp extended on flexible pipe, and existing liquid stopping clamp generally comprises holder, the integrated device intermediate plate on holder, holder is placed through and extends on flexible pipe, can be clamped extend flexible pipe to be formed and stops liquid by coordinating of intermediate plate and holder.But because liquid stopping clamp is installed in extension tube actively, in infusion-completed and the process after stopping liquid, liquid stopping clamp easily swings on indwelling needle, the liquid extended in flexible pipe is caused to produce siphonage and be drawn back into by vessel inner blood in indwelling flexible pipe, cause blood backflow and form thrombosis, have a strong impact on the service time of remaining needle, therefore existing remaining needle generally can only use just remaining needle must be pulled out, the remaining needle more renewed because of the formation of thrombosis for 1-2 days.Particularly because existing liquid stopping clamp is clamping in the process extending flexible pipe because the moment after the intermediate plate of liquid stopping clamp unclamps causes the prolongation flexible pipe clamped to have a resilience because flexible pipe rebounds, the prolongation flexible pipe of former clamping is made to form an elastic rebound and cause blood backflow to arrive in indwelling flexible pipe, cause blood backflow and form thrombosis, affecting the serviceability of remaining needle.Simultaneously because the tip of indwelling flexible pipe is open, change with patient respiration and heart beating the pressure oscillation brought and also there will be blood back and platelet and blood coagulation substance and enter into the phenomenon causing blood coagulation plugging in indwelling flexible pipe.
Summary of the invention
The purpose of this utility model is existence for the problems referred to above and deficiency, there is provided a kind of and ensure that liquid stopping clamp can not drive the bending of the prolongation flexible pipe between liquid stopping clamp and indwelling needle or opisthotonos, avoid the liquid extended in flexible pipe produce siphonage and be drawn back into by vessel inner blood in indwelling flexible pipe, cause blood backflow and thrombosed remaining needle.
On this basis, further object of the present utility model be to provide a kind of structure simple, only liquid effect stability reliable, effectively can avoid the thrombotic remaining needle with spring contact.
The technical solution of the utility model is achieved in that
The sleeved remaining needle of a kind of tool, comprise indwelling flexible pipe, indwelling needle, prolongation base, be connected to indwelling needle and extend prolongation flexible pipe between base, be installed on the liquid stopping clamp extended on flexible pipe, it is characterized in that one end of above-mentioned liquid stopping clamp is provided with the sleeve that can be fixed on indwelling needle sidewall inlet, liquid stopping clamp, is avoided causing because liquid stopping clamp swings extending the swing of flexible pipe and the appearance of twisted phenomena by this sleeve Hard link fixture on the inlet of indwelling needle.
Now, for improving range of application described in the utility model and practicality further, make this utility model can strengthen the working place of medical personnel in operation and reduce the probability that medical personnel touch extension tube, avoid the blood siphonage that the swing owing to extending flexible pipe causes.And facilitate medical personnel's one-handed performance, right-hand man's operation is simultaneously convenient too, solve the medical personnel that original left hand is conventional hands, open the shortcoming that clamp left hand is difficult to open, simultaneously also can reducing liquid stopping clamp because of being fixed on the foreign body sensation that indwelling needle causes, making its angle and remaining needle Y shape seat form a triangle body, reduction liquid stopping clamp is blown out scope, hands can be made to reduce when activity and collide the chance that liquid stopping clamp touches the movement making Y shape seat, the indwelling flexible pipe caused is in the chance of Ink vessel transfusing opisthotonos.Above-mentioned sleeve is arranged at opposite direction end position liquid stopping clamp being positioned at liquid stopping clamp opening.
For realizing further object of the present utility model, ensure this utility model stop liquid effect stability reliable, effectively can avoid thrombosis, above-mentioned liquid stopping clamp pressure touch in the upper contact head of part, lower contact has at least a contact be adopt be different from liquid stopping clamp hard body can to the spring contact extending flexible pipe and formed continuous positive pressure.Or be positioned between the intermediate plate of above-mentioned liquid stopping clamp and holder liquid stopping clamp press the front portion of contact up and down of touching part locate also to be provided with at least one have elastic there is larger clamping area can to the elastic pressuring clamping device extending flexible pipe and formed continuous positive pressure.
This utility model is owing to adopting the sleeved liquid stopping clamp structure of tool, liquid stopping clamp is made to be connected and fixed on indwelling needle, avoid causing because liquid stopping clamp swings extending the swing of flexible pipe and the appearance of twisted phenomena, effectively prevent indwelling needle end extension tube and to swing and distortion causes siphonage to make blood backflow in indwelling needle.Particularly there is the spring contact of continuous positive pressure or the increase of elastic pressuring clamping device, both make liquid stopping clamp intermediate plate reliably clamp and extend flexible pipe formation only liquid, utilize again the spring contact of continuous positive pressure or elastic pressuring clamping device sustainable extruding indwelling needle end to extend flexible pipe to make it deformation occurs, extruding liquid in pipe enters in indwelling flexible pipe, pressure is effectively transmitted in indwelling flexible pipe and forms malleation, effectively avoid the blood backflow that liquid stopping clamp causes in the blood siphon that operation moment causes because flexible pipe rebounds.During remaining needle indwelling, utilize again spring contact or elastic pressuring clamping device to the continuous positive pressure extending flexible pipe, make to produce blood backflow because of venous pressure fluctuation in indwelling flexible pipe, avoid blood backflow in indwelling flexible pipe, reach the object of preventing thrombosis and the service time extending remaining needle to 7-10 days, reduce the increase of misery that patient brings because of repeated localised puncture and medical expense.Especially, the interaction of the tube-in-tube structure of liquid stopping clamp and spring contact or elastic pressuring clamping device makes the liquid in indwelling needle form a continuous positive pressure, further avoid the backflow of blood, reaches the object of preventing thrombosis, and this utility model structure is simple, makes easily practical.
Below in conjunction with accompanying drawing, this utility model is further described.
