Abstract
The utility model discloses a safe infusion device, which comprises an infusion tube with a gas inlet pipe, a Murphy's tube, a control switch and an injection needle head, wherein the two ends of the inner cavity of the Murphy's tube are taper cone shape, in the cavity of the Murphy's tube is provided with a floating ball which corresponds to the tube cavity shape of taper cone shape at both ends and the density is less than the water; between the control switch on the infusion tube and the injection needle head is provided with an injection port and a corresponding plug. The utility model solves the problems of needing the throughout care by the doctors or accompanying service staff during the infusion process, and the safe injection of drugs in the patients, thus to reduce the sufferings of the patients during the infusion process.
Description
Technical field
This utility model relates to field of medical products, especially a kind of safe and reliable safe transfusion system.
Background technology
At present, the most frequently used medical Transfusion device partly is made up of syringe needle, air inlet pipe, liquid-transport pipe-line, Murphy tube, speed regulator etc.During transfusion, treatment liquid enters liquid-transport pipe-line, observes the speed that splashes into by speed regulator from Murphy tube, is changed bottle or is pulled out the pin processing by the medical worker after liquid is totally lost and is finished.But this old-fashioned transfusion device has following weak point: at first, this kind mode must strict be carried out under medical worker or entourage's monitoring, because after one bottle of liquid is totally lost, because old-fashioned transfusion device can not be closed liquid-transport pipe-line automatically, air can directly enter the liquid-transport pipe-line hypomere under the effect of various pressure, need again the exhaust work amount to increase in the time of can causing changing bottle; It is nervous panic that tube for transfusion hypomere blood back causes patient to occur; The infusion needle clottage needs puncture again to add heavy patient's misery; The air accident is advanced in the people patient body, especially during part vein negative pressure, causes patient air embolism to occur, the people's death of seriously can causing a disease.Next is that old-fashioned transfusion device need be pulled down transition joint when needs carry out intravenous injection, pollutes easily, damages to patient.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of the transfusion and intravenous injection safe transfusion system as safe as a house.
For solving the problems of the technologies described above, the technical solution of the utility model is: safe transfusion system, comprise the tube for transfusion, Murphy tube, gauge tap and the injection needle that have air inlet pipe, the two ends of described Murphy tube inner chamber are coniform, and described Murphy tube intracavity is provided with and density corresponding with the cone shape lumen shape in the two ends ball float less than water; Be provided with injection port on the described tube for transfusion between gauge tap and the injection needle and fill in stifled accordingly.
Adopt the safe transfusion system of said structure, by floating of Murphy tube intracavity ball float, this utility model can or be closed liquid-transport pipe-line according to the automatic opening of the situation that no liquid is arranged, and has fundamentally solved the generation that old-fashioned Murphy tube needs aerofluxus again, blood back, syringe needle obstruction, air embolism situation.Solved the problem that need are kept an eye on by doctor or entourage's whole process in infusion process.And by injection port, the doctor can utilize this utility model that patient is carried out the safety injection medicine easily.And this utility model is simple in structure, with low cost, safe and efficient, has reduced patient's painful and uneasy in infusion process.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Fig. 1 is the structural representation of safe transfusion system of the present utility model when normal infusion;
Fig. 2 is the structural representation of safe transfusion system of the present utility model when transfusion finishes.
The specific embodiment
With reference to Fig. 1, a kind of safe transfusion system of the present utility model is: comprise the tube for transfusion 6, Murphy tube 1, gauge tap 2 and the injection needle 3 that have air inlet pipe, two ends at Murphy tube 1 inner chamber are coniform, are provided with and density corresponding with the cone shape lumen shape in the two ends ball float 5 less than water at Murphy tube 1 intracavity; Between gauge tap 2 on the tube for transfusion 6 and injection needle 3, be provided with injection port 4 and corresponding plug stifled 41.
When using the safety transfusion device, under the situation of normally infusing, as shown in Figure 1, ball float 5 swims on the liquid level of Murphy tube 1 intracavity liquid, and transfusion is normally carried out; When liquid is totally lost, as shown in Figure 2, ball float 5 can descend with the decline of Murphy tube 1 intracavity liquid liquid level, when ball float 5 arrives the cone shape tube chamber in Murphy tube 1 intracavity lower end, ball float 5 can be blocked the cone shape tube chamber in Murphy tube 1 intracavity lower end, and the effect of the negative pressure that produces along with the decline of liquid levels is more and more tighter, needs aerofluxus again, blood back, syringe needle obstruction, the generation of the stifled situation of air lock and the problem that will be kept an eye on by doctor or entourage's whole process with regard to having solved old-fashioned Murphy tube in infusion process like this.When needs carry out pressure transfusion and safety injection medicine to patient, as long as gauge tap 2 cuts out, the plug of opening on the injection port 4 blocks up 41, aims at injection port 4 with syringe and carries out the safety injection medicine.
The safety transfusion device is simple in structure, and is easy to operate, safe and reliable, has very big use value.
