Abstract
A sensitive blood return infusion apparatus comprises an infusion catheter. An intravenous infusion needle is arranged at one end of the infusion catheter, a bottle stopper puncture device is arranged at the other end of the infusion catheter, a dripping bucket, a flow regulator and a medicine liquid filter are sequentially arranged on the infusion catheter between the bottle stopper puncture device and the intravenous infusion needle, and a sensitive blood return device is arranged on the infusion catheter between the medicine liquid filter and the intravenous infusion needle. By utilizing the sensitive blood return device arranged between the medicine liquid filter and the intravenous infusion needle, medical staff is facilitated to clearly see whether a vein of a patient is stabbed or not; by utilizing a blood return balloon arranged in the middle of a sensitive blood return tube, the objective of blood return can be achieved through contraction and expansion along with different pressure; the wall thickness of the blood return balloon is gradually increased from the middle to two ends, so that the objective of sensitive blood return can be achieved. The sensitive blood return infusion apparatus is simple in structure, reasonable in design, sensitive in blood return and stable in using effect.
Description
Technical field
The present invention relates to a kind of medicine equipment, particularly a kind of sensitive blood returning transfusion system.
Background technology
At present, when needs of medical treatment are infused, medical personnel will observe syringe needle and woven hose in the link of venipuncture
Whether junction has blood backflow phenomenon --- and blood back occurs, once blood back occur proves that syringe needle has been enter into vein, so that
Infusion treatment work after a while can be carried out.But medical personnel can run into panoramic patient during transfusion, bag
Blood back relatively difficult patient when including the thinner acupuncture treatment of some blood vessels, such as infant or the elderly, and some blood pressures
Hypodynamic patient cannot observe its blood back state, cause transfusion device blood back difficult, cause medical personnel to learn that vein is defeated
Whether liquid pin penetrates blood vessel, if puncture unnecessary pain can be increased to patient back and forth, meanwhile, also increase the labor of medical personnel
Fatigue resistance.
The content of the invention
The technical problem to be solved in the present invention is directed to the deficiencies in the prior art, proposes that a kind of blood back effect substantially, can keep away
Exempt to puncture the sensitive blood returning transfusion system for bringing pain to patient back and forth.
The technical problem to be solved in the present invention is achieved through the following technical solutions.The present invention is that a kind of sensitive blood-return is defeated
Liquid device, including transfusion catheter, one end of transfusion catheter are provided with intravenous infusion needle, and the other end of transfusion catheter is provided with bottle stopper puncture
Device, dropping funnel, flow regulator and medical filtration are sequentially provided with the transfusion catheter between bottle plug puncture unit and intravenous infusion needle
Device, is characterized in：Sensitive blood back flowing device, sensitive blood-return are provided with transfusion catheter between liquid medicine filter and intravenous infusion needle
Device includes base, and the liquid import and export communicated with transfusion catheter is respectively equipped with the upper/lower terminal of base, is set in base
There are the liquid medicine flow passages of connection liquid import and medicine liquid outlet, opening of being communicated with liquid medicine flow passages is provided with the side of base
Mouthful, lid is installed at opening, the sensitive blood-return pipe being fixedly connected with lid is installed, sensitive in the liquid medicine flow passages
Blood back sacculus is provided with the middle part of blood return tube, the wall thickness of blood back sacculus is gradually thickening from middle part to two ends, in the blood back sacculus
Portion's wall thickness is 0.3-0.5mm, is fixed with protective cover outside sensitive blood-return pipe, and protective cover is by the case welding group that is symmetrical set
Into, be equipped with left and right case with blood back sacculus heave state cooperation arc convex.
In a kind of sensitive blood returning transfusion system technical scheme of the present invention, further preferred technical scheme is characterized in：
1st, the sensitive blood-return pipe is silicone tube；
2nd, the middle part wall thickness of the blood back sacculus is 0.4mm；
3rd, the sensitive blood-return pipe is hollow blood return tube, and the convex coordinated with hollow blood back inside pipe wall is provided with the inside of lid
Rise.
Compared with prior art, the present invention is using the sensitive blood-return dress being arranged between liquid medicine filter and intravenous infusion needle
Put, contribute to medical personnel to see the vein blood vessel for whether pricking patient；Using the blood back being arranged in the middle part of sensitive blood-return pipe
Sacculus, the purpose of blood back is reached as different pressure is shunk and expanded；By the wall thickness of blood back sacculus from middle part to two
End is gradually thickening, can reach the purpose of sensitive blood-return.Simple structure of the present invention, reasonable in design, blood back is sensitive, and using effect is steady
It is fixed.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of sensitive blood back flowing device.
Specific embodiment
Referring to the drawings, concrete technical scheme of the invention is further described, is entered in order to those skilled in the art
One step ground understands the present invention, without constituting the limitation to its right.
Embodiment 1, reference picture 1,2, a kind of sensitive blood returning transfusion system, including transfusion catheter 5, one end of transfusion catheter 5 sets
The other end for having intravenous infusion needle 7, transfusion catheter is provided with bottle plug puncture unit 1, between bottle plug puncture unit 1 and intravenous infusion needle 7
Transfusion catheter on be sequentially provided with dropping funnel 3, flow regulator 4 and liquid medicine filter 2, in liquid medicine filter 2 and intravenous infusion needle 7
Between transfusion catheter be provided with sensitive blood back flowing device 6, sensitive blood back flowing device 6 includes base 8, in the upper/lower terminal point of base 8
The liquid import and export communicated with transfusion catheter is not provided with, and the liquid stream of liquid import and medicine liquid outlet is communicated with base
Circulation passage, the opening communicated with liquid medicine flow passages is provided with the side of base, and lid 9, the liquid stream are provided with opening
The sensitive blood-return pipe 10 being fixedly connected with lid is installed in circulation passage, blood back sacculus is provided with the middle part of sensitive blood-return pipe 10
14, the wall thickness of blood back sacculus 14 is gradually thickening from middle part to two ends, and the middle part wall thickness of the blood back sacculus is 0.3-0.5mm,
Protective cover is fixed with outside sensitive blood-return pipe, protective cover is welded to form by the case 11 being symmetrical set, on left and right case 11
It is equipped with the arc convex 12 that state cooperation is heaved with blood back sacculus.The blood back sacculus when not having pressure, suppress by centre；
When there is certain pressure, center section can reach the purpose of blood back, institute as different pressure is shunk and expanded
Blood back sacculus both sides wall thickness is stated for 1.0-2.0mm, the intermediate thin of blood back sacculus is because original blood pressure is very low, if middle wall thickness surpasses
