Abstract
The utility model relates to a venous infusion device. The venous infusion device comprises an infusion component which comprises an infusion tube, a dripping bottle and a puncture needle. The infusion tube comprises a top-section infusion tube and a bottom-section infusion tube which are connected through the dripping bottle, an air tube for regulating the air pressure is arranged at the liquid feeding end of the dripping bottle, a water stop is arranged on the bottom-section infusion tube, and a tightening unit for producing negative pressure during puncturing needle feeding is arranged on the bottom-section infusion tube. The venous infusion device is capable of facilitating back flow of needle feeding blood, simple in structure, low in cost and convenient to operate.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of transfusion device, relates in particular to a kind of intravenous infusion device.
Background technology
At present, in clinical treatment process, when many patient, need to give medicine by vein leaves, when particularly patient's state of an illness sharply changes or rescues in batch the wounded, intravenous medicine is one of necessary emergency measures especially; In venous transfusion process, there is an important link, in acupuncture treatment process, must occur blood backflow exactly, otherwise will be considered as infusing unsuccessfully, need to be from new acupuncture treatment transfusion.
Traditional intravenous infusion device is because tube for transfusion is closed poor flexibility, and lumen diameter is little, intrinsic pressure large, again because of the effect of fluid pressure and gravity, exists blood back resistance large, and the problem that leeway is few easily causes blood back slowly or loses the situation of blood back.
In rescue process, can run into unavoidably the patient of infant, body obesity, edema, dewaterer long-term infusion; this class treatment crowd also often there will be special circumstances; as: blood vessel is too tiny; the situations such as patient's hypopiesia; this class situation all can cause intravenous infusion syringe correctly to insert the phenomenon that blood backflow still can not appear in blood vessel in time; therefore be mistaken for puncture failure, again acupuncture treatment.This has caused very large trouble to medical personnel, has also delayed the rescue time of patient's preciousness simultaneously.
Utility model content
In order to solve existing technical problem in background technology, the utility model proposes a kind of can effectively solve that blood do not reflux intravenous infusion device.
Technical solution of the present utility model: a kind of intravenous infusion device, comprises infusion set; Described infusion set comprises the tube for transfusion, droplet kettle and the piercing needle that connect successively along flow direction; Described tube for transfusion comprises the epimere tube for transfusion and the lower end tube for transfusion that connect by dripping kettle; Described kettle liquid feeding end is provided with the air hose for adjustable pressure; Only on described hypomere tube for transfusion, be provided with water; It is characterized in that: on above-mentioned hypomere tube for transfusion, be also provided with the clamping device for generation of negative pressure in the time of puncture inserting needle;
Above-mentioned clamping device comprises and steps up sheet and produce adding of negative pressure for stepping up tube for transfusion to link closely, and steps up sheet one end and is flexibly connected with adding to link closely.
The beneficial effects of the utility model are: the utility model proposes and a kind ofly can effectively solve the intravenous infusion device that venous transfusion when acupuncture treatment blood does not reflux, by produce certain negative pressure in tube for transfusion, after syringe needle penetrates blood vessel negative pressure can certainly be about to blood extract out, cause backflow.This apparatus structure is simple, with low cost, easy to operate.

Detailed description of the invention
Referring to Fig. 1-2, a kind of intravenous infusion device, comprises infusion set; Infusion set comprises the tube for transfusion, droplet kettle 3 and the piercing needle 6 that connect successively along flow direction; Tube for transfusion comprises the epimere tube for transfusion 2 and the lower end tube for transfusion 7 that connect by dripping kettle 3; Drip kettle 3 liquid feeding ends and be provided with the air hose for adjustable pressure; On hypomere tube for transfusion 7, be provided with water and stop 4; On hypomere tube for transfusion 7, be also provided with the clamping device 5 for generation of negative pressure in the time of puncture inserting needle.
Drip kettle below tube for transfusion and be provided with water only 4 apart from the about 20-30 centimeters of tube for transfusion end 6, regulate the speed of liquid droping speed, on hypomere tube for transfusion 7, be also provided with the front clamping device 5 for generation of negative pressure of piercing needle 6 inserting needles, clamping device 5 comprises and steps up sheet 51 and produce adding of negative pressure for stepping up the tube for transfusion of tube for transfusion end 7 tops to link closely 52, steps up sheet 51 and 52 is flexibly connected with adding to link closely.
In the time carrying out venipuncture, water is only moved to apart from the position of the about 20-30 of tube for transfusion end centimetre and only close water, then make the liquid in the tube for transfusion of water only and between clamping device be forced to flow out from puncture needle head by the clamping device on nearly tube for transfusion end, allow in this section of tube for transfusion generation negative pressure naturally, and close clamping device, inserting needle afterwards punctures, in whole inserting needle process, negative pressure in the tube for transfusion of water only and between clamping device exists all the time, in the time of inserting needle, determine after needle slope enters subcutaneous tissue completely and unclamp clamping device, now water stops in following tube for transfusion, in piercing needle and piercing needle flexible pipe, be negative pressure, continue inserting needle, once needle slope intravasation, due to the swabbing action of negative pressure, visible blood is back to rapidly in piercing needle flexible pipe, determine and puncture successfully, the acupuncture treatment failure of having avoided error in judgement to cause, improve greatly success rate, reduce patient's misery, improve work efficiency.
