Abstract
The utility model discloses a safe medical infusion device and more particularly relates to a medical instrument, in particular to the safe medical infusion device. The safe medical infusion device comprises a Murphy dropper as well as a liquid catheter and an infusion tube which are connected with two ends of the Murphy dropper; an internal cavity of the Murphy dropper is provided with a floating ball; the diameter of the floating ball is more than the internal diameter of the infusion tube; and a port of the infusion tube is flush with a lower port of the Murphy dropper. The safe medical infusion device disclosed by the utility model has the advantages of simple structure, low cost, simpleness in manufacturing, economy and practicability and capability of effectively preventing air from entering the infusion tube, resulting in blood-backflow situations; and the infusion safety is guaranteed and convenience is provided for operation of nursing staff.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of safe medical transfusion device.
Background technology
Transfusion device uses clinically in a large number, because the patient infusion time is longer, the person of accompanying and attending to or patient are easy to generate feeling of fatigue; In case medicinal liquid drips off; Because of the nursing staff has little time nursing or the not discovery of the sleeping back of patient, the phenomenon of blood back will appear, increase patient's misery.And after infusion bottle drips sky, if patient's regulating and controlling switch not, or medical personnel can not in time change liquid; Cause medicinal liquid often to drop to below the Mo Feishi dropper; Air in the infusion bottle is got in the tube for transfusion with bubble form, all will get rid of the bubble in the tube for transfusion at every turn when causing the nursing staff to change liquid, this not only brings certain trouble to the nursing staff; And pollute easily; Therefore, conventional transfusion device brings potential safety hazard not only for transfusion person, also brings the inconvenience in the work to medical personnel.For a kind of safe medical Transfusion device is provided; Many technical solutions have appearred; As through setting up control valve or optoelectronic induction dispatch control system, because these technical schemes have increased control device, bring the transfusion device complex structure, production cost is higher, makings is difficult, operate problems such as inconvenience.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, this utility model purpose provides a kind of simple in structure, safe medical transfusion device that cost is lower, economical and practical.
For achieving the above object; This utility model is realized through following technical scheme: the described safe medical transfusion device of this utility model; Comprise Mo Feishi dropper and the catheter and the tube for transfusion that are connected with Mo Feishi dropper two ends; The inner chamber of described Mo Feishi dropper is provided with a ball float, and the diameter of said ball float is greater than the internal diameter of tube for transfusion, and the described tube for transfusion mouth of pipe is concordant with the lower port of Mo Feishi dropper.
The described ball float of this utility model can be hollow shape or solid shape.
Compared with prior art, the described safe medical transfusion device of this utility model, simple in structure, cost is low, making is simple, economical and practical; Can effectively prevent the air admission tube for transfusion; Can not cause the blood back phenomenon, so both guarantee transfusion safety, again the convenient nursing personnel operation.
Description of drawings
Fig. 1 is the user mode structural representation in this utility model infusion process.
Fig. 2 is this utility model transfusion user mode structural representation after accomplishing.
The 1-catheter, 2-Mo Feishi dropper, 3-ball float, 4-tube for transfusion.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described, but is not limited to embodiment.
Embodiment 1
As shown in Figure 1; The described safe medical transfusion device of this utility model comprises Mo Feishi dropper 2 and the catheter 1 and the tube for transfusion 4 that are connected with Mo Feishi dropper 2 two ends, is provided with a ball float 3 at the inner chamber of Mo Feishi dropper 2; Ball float 3 usefulness proportions are made less than lightweight, the non-toxic material of water; Ball float 3 can be made into hollow or solid shape, and the diameter of ball float 3 is greater than the internal diameter of tube for transfusion 4, and the lower end of Mo Feishi dropper 2 is set to cone-shaped.When normal infusion, the ball float 3 in Mo Feishi dropper 2 inner chambers is lighter than water because of its proportion, and ball float 3 just can swim in the medicinal liquid surface, does not influence normal infusion.When medicinal liquid was about to be totally lost, ball float 3 just descends along with the liquid level of medicinal liquid together, and was as shown in Figure 2; Ball float 3 is reduced to the lower port of Mo Feishi dropper 2 at last, because the diameter of ball float 3 is greater than the internal diameter of tube for transfusion 4, and the lower end of Mo Feishi dropper 2 is a cone-shaped; Narrow gradually, when ball float 3 is reduced to the lower port of Mo Feishi dropper 2, because tube for transfusion 4 mouths of pipe are concordant with the lower port of Mo Feishi dropper 2; Just just in time with the internal diameter mouth of tube for transfusion 4 stifled on; And the arc section of ball float 3 just in time can form good sealing effectiveness between Mo Feishi dropper 2 lower port taper surfaces, makes air can not get into tube for transfusion 4, also the blood back phenomenon can not occur; Both guaranteed transfusion safety, again the convenient nursing personnel operation.
Claims (3)
1. safe medical transfusion device; Comprise Mo Feishi dropper and the catheter and the tube for transfusion that are connected with Mo Feishi dropper two ends; It is characterized in that: the inner chamber of described Mo Feishi dropper is provided with a ball float; The diameter of said ball float is greater than the internal diameter of tube for transfusion, and the described tube for transfusion mouth of pipe is concordant with the lower port of Mo Feishi dropper.
