Description
Technical field
The utility model is related to a kind of Medical Devices, more particularly to a kind of remaining needle of high pressure resistant Anti-bubble.
Background technology
At present, in medicine equipment, remaining needle is widely used, and remaining needle greatly facilitates the injection of decoction and defeated
Liquid.But the drawbacks of traditional remaining needle is all the injection using single flow, such electrolyte filling method when to human body fluid injection is straight
The injection of streaming often forms minute bubbles in the sap cavity of remaining needle, and if minute bubbles are input in human vas, to defeated
Liquid patient brings potential safety hazard.
The indwelling protection injection nested structure of traditional remaining needle is all knockdown structure in addition, can not thus ensure it
The sealing of itself, and structural stability is poor, resistance to pressure to external world is excessively poor, it is impossible to ensure infusion safety.
Utility model content
The utility model is in order to solve the above-mentioned deficiency of prior art, it is proposed that a kind of remaining needle of high pressure resistant Anti-bubble.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：A kind of high pressure resistant Anti-bubble is stayed
Pin, including indwelling needle component are put, the indwelling needle component is provided with needle injection joint and injection out splice going splice, the note
Penetrate and transfusion catheter is connected with out splice going splice, further comprise indwelling protection injection set, the interior of set is injected in the indwelling protection
Portion has a transfusion host cavity, the transfusion host cavity, the conduit adapter sleeve of the side of the upper end of the transfusion host cavity, institute
State transfusion catheter and be connected to the conduit adapter sleeve；The opposite side of the upper end of the transfusion host cavity is described provided with outlet end mouthful
The side of outlet end mouthful is provided with liquid outlet channel, the bottom transfusion cushion chamber of the liquid outlet channel, the bottom peace of the liquid cushion chamber
Equipped with steel pricker.
Further, the inner chamber of described injection out splice going splice is horizontally installed with an infusion filter film.
Further, the side of described indwelling protection injection set, which is provided with, connects in the ventilative blocking solution of transfusion host cavity
Piece.
Further, the top of described steel pricker is provided with casing seat.
Further, the outside of described indwelling protection injection set is provided with hand holding handle.
Compared with prior art, the utility model employs transfusion host cavity and the outlet end mouth structure of side, thus
The decoction for avoiding transfusion catheter inflow is directly poured into human body, and the problem of being also directly inputted to human body with regard to the bubble in decoction is sent out
It is raw, the decoction in transfusion catheter can be allowed to be introduced into transfusion host cavity and give certain buffering, allow to form bubble breaking, Ran Houzai
Inputted into the human body from outlet end mouthful, and be provided with ventilative liquid barrier discharge bubble, eliminate bubble, it is ensured that the safety of transfusion.
Indwelling protection injection nested structure of the present utility model is Integral injection molded integrative-structure in addition, and this makes it possible to ensure its own
Sealing, and structural stability is high, resistance to pressure to external world is very good, it is ensured that transfusion is perfectly safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model proposes a kind of high pressure resistant Anti-bubble remaining needle, including indwelling needle component 1,
Indwelling needle component 1 is injected provided with needle injection joint 2 and injection out splice going splice 3 and is connected with transfusion catheter on out splice going splice 3
4, in addition to indwelling protection injection set 5, indwelling protection injection set 5 inside have one transfusion host cavity 6, infuse host cavity 6,
The side conduit adapter sleeve 7 of the upper end of transfusion host cavity 6, transfusion catheter 4 is connected to the conduit adapter sleeve 7.Transfusion host cavity 6
Upper end opposite side provided with outlet end mouthfuls 8, the side of outlet end mouthful 8 is provided with liquid outlet channel 9, and the bottom of liquid outlet channel 9 is infused
Cushion chamber 10, the bottom of the liquid cushion chamber 10 is provided with steel pricker 11.It is defeated that the inner chamber of injection out splice going splice 3 is horizontally installed with one
Liquid filter membrane 12.
The side of indwelling protection injection set 5, which is provided with, to be connected in the ventilative liquid barrier 13 of transfusion host cavity 6.
The top of steel pricker 11 is provided with casing seat 14.The outside of indwelling protection injection set 5 is provided with hand holding handle 15.
In the utility model, decoction is entered in transfusion catheter from the injection out splice going splice 3 of indwelling needle component 1, and
Pass through infusion filter film 12, be filled into the impurity in decoction, after transfusion host cavity is entered, form the accumulation of decoction, this
Sample just gives certain buffering to decoction, allows to form bubble breaking, is then inputted into the human body from outlet end mouthful again, and is provided with
Ventilative liquid barrier discharge bubble, eliminates bubble, it is ensured that the safety of transfusion.Noose is injected in indwelling protection of the present utility model in addition
