Abstract
The utility model belongs to the field of medical apparatus and instruments, and provides a novel remaining needle. The novel remaining needle is characterized in that a plane is arranged on the outer surface of the front end of a Y-shaped catheter seat of an existing remaining needle, the plane inclines towards the axis of a sleeve of the remaining needle, a transfusion connector of the remaining needle is connected with an exhaust cap, an exhaust pipe is arranged on the exhaust cap, a puncture end of the exhaust pipe rightly penetrates through sealant of the transfusion connector, and the outer end of the exhaust cap is provided with a hydrophobic membrane. The novel remaining needle reduces bending degree of the sleeve of the remaining needle, is beneficial for improving transfusion effect, and meanwhile avoids discomfort in physiology and psychology of a patient because the sleeve of the remaining needle tilts. Due to the fact that the exhaust cap is connected with the transfusion connector, when a medical worker uses the remaining needle to carry out puncture, blood enters a transfusion catheter of the remaining needle, air in the catheter is forced into the exhaust cap through the transfusion connector, and is discharged through the hydrophobic membrane, and the air is effectively prevented from being left in the remaining needle.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of Novel remaining needle.
Background technology
Remaining needle is a kind of armarium that repeatedly carries out within a certain period of time infusion treatment, and remaining needle claims again the trocar, generally comprises: infusion connector, transfusion catheter, Y shape catheter block, puncture draw point and remaining needle sleeve pipe.The remaining needle sleeve pipe is made by the transparent organism material, has softness, tough and tensile large, the characteristics that are difficult for the injured blood vessel wall.During clinical use, at first with medicinal liquid, the air in remaining needle is drained, the puncture draw point leads the remaining needle sleeve pipe to enter the blood vessel of human body, and after confirming to puncture successfully, the draw point that will puncture is extracted out, and the remaining needle sleeve pipe is retained in blood vessel.The remaining needle sleeve pipe can be used safely in safe indwelling time, can accomplish at any time venous transfusion for operation, neonate, the patient such as critical, guarantees treatment, avoids frequent puncture to the misery that the patient brings, and has also alleviated nurse's workload.
At present, before existing retained needle puncture, must couple together with transfusion system, utilize the medicinal liquid deaeration.This process not only operates inconvenience, and is difficult to air is drained fully, the air in infusion connector especially, and these gases probably are brought into human body in infusion process; In addition, the front end of its Y shape catheter block of existing remaining needle is cylindric, there is larger angle between the contact point of remaining needle sleeve pipe and Y shape catheter block front end and skin, because the remaining needle sleeve pipe is more soft, position in remaining needle sleeve pipe and contact skin, the phenomenon that bends or be upturned easily appears in the remaining needle sleeve pipe, on the one hand due to remaining needle sleeve pipe bending impact transfusion effect, the remaining needle sleeve pipe of perk easily brings uncomfortable sensation to the patient on the other hand, also easily allow the patient feel frightened, bring psychologically discomfort at it, the impact treatment.
The utility model content
For the defects that existing remaining needle exists, this utility model provide a kind of namely can automatic vent, can reliably infuse again, guarantee that patient feels comfortable Novel remaining needle.
this utility model is that the technical scheme that its technical problem of solution is taked is, design a kind of Novel remaining needle, its structure comprises infusion connector, transfusion catheter, the Y shape catheter block, puncture draw point and remaining needle sleeve pipe, infusion connector is connected with the Y shape catheter block by transfusion catheter, front end at the Y shape catheter block is connected with described remaining needle sleeve pipe, the front end outer surface of wherein said Y shape catheter block is provided with a plane to the inclination of remaining needle casing axis, the angle of described plane and remaining needle casing axis is 18 °, be connected with exhaust cap on described infusion connector, be provided with exhaustor on exhaust cap, the cutting tip of exhaustor just passes the fluid sealant of infusion connector, the outer end of described exhaust cap is provided with hydrophobic membrane.
this utility model is by front end outer surface design one clinoplain at catheter block, when catheter block is contacted with patient skin, the axis of remaining needle sleeve pipe and the angle between skin reduce, alleviated the degree of being bent into of remaining needle sleeve pipe, be conducive to improve the transfusion effect, simultaneously also avoided the perk of remaining needle sleeve pipe to bring physiology and psychological discomfort to the patient, also be connected with exhaust cap on infusion connector, when medical personnel utilize remaining needle to puncture, blood enters the retention needle infusion conduit, gas in conduit is approached in exhaust cap through infusion connector, and discharge through hydrophobic membrane, the characteristic of the hydrophobic membrane of this programme only allows the air process and does not allow the liquid process, so this process blood can be stopped by hydrophobic membrane, prevent from flowing out, at this moment pull out exhaust cap, all there is no air in the passage of whole remaining needle, lunging transfusion needle infuses again, so just effectively avoid leaving in remaining needle air.

Fig. 1 is the overall structure schematic diagram of a kind of Novel remaining needle of this utility model.
The specific embodiment
Claims (1)
1. Novel remaining needle, comprise infusion connector, transfusion catheter, the Y shape catheter block, puncture draw point and remaining needle sleeve pipe, infusion connector is connected with the Y shape catheter block by transfusion catheter, front end at the Y shape catheter block is connected with the remaining needle sleeve pipe, it is characterized in that being provided with a plane to the inclination of remaining needle casing axis at the front end outer surface of described Y shape catheter block, the angle of described plane and remaining needle casing axis is 18 °, be connected with exhaust cap on described infusion connector, be provided with exhaustor on exhaust cap, the cutting tip of exhaustor just passes the fluid sealant of infusion connector, the outer end of described exhaust cap is provided with hydrophobic membrane.
