Abstract

The utility model discloses a kind of remaining needle, including indwelling needle, extend base, be connected to indwelling needle and extend extending flexible pipe, be arranged at the liquid stopping clamp extended on flexible pipe between base, it is characterized in that being set with trocar sheath outside described prolongation flexible pipe, being provided with otch on described trocar sheath, liquid stopping clamp is clamped in trocar sheath incision.This utility model simple in construction, easy to use, only liquid is reliable for effect, improves the safety of use.

Description

A kind of remaining needle
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of remaining needle.
Background technology
The use of remaining needle can effectively reduce the misery that venipuncture repeatedly causes to patient, and facilitates clinical application, anxious, The rescue medication of critical patient, alleviates the workload of nurse, and is widely used in clinic.Existing remaining needle generally comprises and stays Put flexible pipe, indwelling needle, extension tube, the prolongation flexible pipe being connected between indwelling needle and prolongation base, be installed on prolongation flexible pipe On liquid stopping clamp.Currently used liquid stopping clamp is unreliable to the clamping effect extending flexible pipe, in infusion-completed and only mistake after liquid Cheng Zhong, liquid stopping clamp easily swings on indwelling needle, cause the liquid extending in flexible pipe to produce siphonage and by Ink vessel transfusing blood Liquid is drawn back in indwelling flexible pipe, causes blood backflow to form thrombosis, and affects the use of remaining needle.
Utility model content
The purpose of this utility model is to overcome above-mentioned technological deficiency, it is provided that a kind of remaining needle, its simple in construction, user Just, only liquid is reliable for effect.
To achieve these goals, the scheme of employing is as follows for this utility model:
A kind of remaining needle, including indwelling needle, extends base, is connected to indwelling needle and the prolongation extended between base is soft Pipe, the liquid stopping clamp being arranged on prolongation flexible pipe, is characterized in that being set with trocar sheath, on described trocar sheath outside described prolongation flexible pipe Being provided with otch, liquid stopping clamp is clamped in trocar sheath incision.
Described liquid stopping clamp includes locking boss, intermediate plate and holder, and when locking boss separates with intermediate plate, liquid stopping clamp is in and opens State, extends flexible pipe and is internally located at holder from the two gap entrance liquid stopping clamp, liquid stopping clamp lock when locking boss closes with intermediate plate Fixed, prolongation flexible pipe is gripped by the lower edge of intermediate plate with holder.More preferably, intermediate plate lower edge is provided with latch, and latch snaps in overcoat In the otch of pipe.It is provided with limited impression on holder, extends flexible pipe and fall in limited impression.
Described intermediate plate is arranged on elastic arm, and elastic arm is provided with anti-slip veins.
The utility model has the advantages that to extend at remaining needle and on flexible pipe, trocar sheath be set on trocar sheath, have the convenient only liquid of otch Folder reliable retention extends flexible pipe.Latch on the intermediate plate of liquid stopping clamp especially intermediate plate gos deep into trocar sheath otch so that liquid stopping clamp pair The clamping extending flexible pipe is more firm, stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model remaining needle.
Fig. 2 is partial enlarged drawing of the present utility model.
Fig. 3 is the structural representation of trocar sheath.
Fig. 4 is the structural representation of liquid stopping clamp.
In figure, 1 extends base, 11 positive valves, 12 positive pressure connectors, 13 end caps, and 2 prolong soft long tube, 3 trocar sheaths, 31 otch, and 4 Liquid stopping clamp, 41 locking boss, 42 latches, 43 holders, 44 limited impressions, 45 anti-slip veins, 46 intermediate plates, 47 elastic arms, 5 remaining needles Seat, 6 hold needle handle.
Detailed description of the invention
Remaining needle of the present utility model, as it is shown in figure 1, include indwelling needle 5, prolongation base 1, be connected to indwelling needle 5 And the prolongation flexible pipe 2 extended between base 1, the liquid stopping clamp 4 being arranged on prolongation flexible pipe 2, extend and be provided with positive valve on base 1 11, positive pressure connector 12, end cap 13 etc., indwelling needle 5 connects holds needle handle 6, and these are routine techniques, repeat no more.
Extending and be set with trocar sheath 3 outside flexible pipe 2, trocar sheath 3 and the outer wall extending flexible pipe 2 fit together, at overcoat Being provided with otch 31 on pipe 3, liquid stopping clamp 4 is clamped at the otch 31 of trocar sheath.
In the present embodiment, liquid stopping clamp 4 includes locking boss 41, intermediate plate 46 and holder 43, and intermediate plate 46 is arranged on elastic arm 47 On, elastic arm 47 is provided with anti-slip veins 45, convenient manipulation elastic arm 47.Outwardly open elastic arm 47, locking boss 41 with Intermediate plate 46 separates, and now liquid stopping clamp 4 is in open mode, extends flexible pipe 2 and is internally located at holder from the two gap entrance liquid stopping clamp On 43, holder 43 is provided with limited impression 44, extends flexible pipe 2 and fall in limited impression 44 that (adjustment makes trocar sheath 3 fall into limit In the groove 44 of position), inwardly close elastic arm 47, lock convex 41 and close with intermediate plate 46, now liquid stopping clamp 4 locks, intermediate plate 46 times Prolongation flexible pipe 2 is gripped by edge with holder 43.Intermediate plate 46 lower edge is provided with latch 42, and latch 42 snaps in the otch of trocar sheath In 31, can further improve the liquid stopping clamp 4 clamping effect to prolongation flexible pipe 2, improve the safety that remaining needle uses.
