Abstract
The utility model relates to medical device technical field, in particular to a safety valve type infusion set which comprises an inserting needle, an upper infusion tube, a dripping bucket, a lower infusion tube, an adjusting switch and an injecting needle. The dripping bucket is provided with a safety valve seal device consisting of a valve and a valve cover; the valve and the dripping bucket are integrating molded, and the valve cover is movably connected with the valve by a pin; the lower part of the dripping bucket is provided with a pressure gasbag. The unique infusion set with simple structure can effectively prevent blood return and dangers like air embolism and thrombus of human body when infusing with the infusion set, avoid medical contamination and reduce dispute between doctor and patient effectively.
Description
Technical field:
This utility model relates to technical field of medical instruments, refers in particular to a kind of relief valve formula transfusion device.
Background technology:
Transfusion device is as a kind of medical apparatus and instruments commonly used in the medical treatment, in the process of the treatment of giving patient, brought into play important effect, at present, we common to transfusion device comprise contact pin, upper tubing, dropping funnel, tube for transfusion, by-pass cock and entry needle down, if when the transfusion device that adopts this structure carries out infusion treatment to the patient, after medicinal liquid is totally lost, entry needle is pulled out untimelyly, will bring certain potential safety hazard, because if untimely pulling out, because the phenomenon that blood refluxes can appear in the effect of venous pressure; Also may cause the air embolism of human body because the effect of negative pressure makes gas enter vein; No matter be that the reflux blood that forms of blood is fastened or when the air admission blood vessel, all might be caused personnel's death when serious.So medical personnel will often observe the transfusion situation when using the transfusion device of this structure now, particularly medicinal liquid remaining not for a long time medical personnel can not leave easily especially.This not only can bring many inconvenience to medical personnel, handles untimelyly also can bring certain harm to the patient, also might cause some doctor-patient disputes simultaneously.And if after the transfusion device that causes blood to reflux used up, if deal with improperly then can cause certain pollution, its remaining blood might become propagated some viral roots, brings great harm to society.So, develop the urgent needs that a kind of transfusion device safe and easy to use has become numerous relevant producers and medical worker.
The utility model content:
The purpose of this utility model is, at above problem, provides a kind of relief valve formula transfusion device by innovative technology.
For achieving the above object, this utility model adopts following technical scheme: relief valve formula transfusion device, it comprises: transfusion device contact pin, upper tubing, dropping funnel, tube for transfusion, by-pass cock and entry needle down are provided with a safety valve sealing device of being made up of valve and valve gap in described dropping funnel; Described valve and dropping funnel are one-body molded, and valve gap flexibly connects by pin and valve.
Be provided with a pressure air bag in described dropping funnel bottom.
The beneficial effects of the utility model are: adopted to comprise: transfusion device contact pin, upper tubing, dropping funnel, tube for transfusion, by-pass cock and entry needle down are provided with a safety valve sealing device of being made up of valve and valve gap in described dropping funnel; Described valve and dropping funnel are one-body molded, and valve gap flexibly connects by pin and valve; Be provided with a pressure air bag in described dropping funnel bottom.A kind of like this transfusion device of uniqueness, not only simple in structure, and it occurs that blood refluxes can effectively prevent to use transfusion device to infuse the time and dangerous situations such as the air embolism that causes to human body, thrombosis, and meanwhile it can also effectively be avoided medical treatment to pollute and reduce doctor-patient dispute.
Description of drawings:
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is the structural representation of this utility model valve gap when opening.
Structural representation when Fig. 2 is this utility model valve gap closure.
The specific embodiment:
See accompanying drawing 1, accompanying drawing 2; Relief valve formula transfusion device, it comprises: transfusion device contact pin 1, upper tubing 2, dropping funnel 3, tube for transfusion 4, by-pass cock 5 and entry needle 6 down are provided with a safety valve sealing device of being made up of valve 7 and valve gap 8 in described dropping funnel 3; Described valve 7 is one-body molded with dropping funnel 3, and valve gap flexibly connects by pin and valve, is provided with a pressure air bag 9 in described dropping funnel 1 bottom.When not using this transfusion device, valve gap 8 rests on the valve 7 and is sealed and matched with it, when infusing, at first push dropping funnel 3 to patient, this moment, medicinal liquid began to enter dropping funnel 3, and then squeeze pressure air bag 9 makes its pressure that produces force valve gap 8 to be opened, by after medical personnel's aerofluxus the patient being infused.In the infusion process, described valve gap 8 is in suspended state and does not influence normally carrying out of transfusion, and when transfusion is finished, 8 of valve gaps fall back to the liquid outlet that closely cooperates mutually with it on the valve 7 dropping funnel 3 and seal, can effectively prevent owing to patient's vein pressure thereby play, and the generation of dangerous situations such as blood back phenomenon that occurs and air embolism.And in the time will carrying out next bottle transfusion, then can push dropping funnel 3 and pressure air bag 9 once more and repeat above-mentioned process, and do not need to insert once more entry needle 6, and such infusion process is safer, and the danger that has not only reduced patient has also reduced the trouble of medical personnel's operations.
Relief valve formula transfusion device is not only simple in structure, and it occurs that blood refluxes can effectively prevent to use transfusion device to infuse the time and dangerous situations such as the air embolism that causes to human body, thrombosis, and meanwhile it can also effectively be avoided medical treatment to pollute and reduce doctor-patient dispute.
Certainly; the embodiment of the above; it is preferred embodiments of the present utility model; be not to limit this utility model practical range; so all variation or modifications of doing according to the described structure of this utility model claim, feature and principle all should be included in the scope of this utility model patent protection.
