Abstract

The utility model relates to a medical device technical field, in particular to a pressure air sac type infusion set which comprises an infusion set inserting needle, an upper infusion tube, a dropping bucket, a lower infusion tube, an adjusting switch and an injection needle. The dropping bucket is provided with a taper piston capable of moving up and down inside the dropping bucket and a pressure air sac below the dropping bucket. The unique infusion set with simple structure can effectively prevent dangers of blood returning, air embolism and thrombus during infusion with the infusion set and effectively avoid medical pollution and reduce medical dispute.

Description

Pressure gasbag-type transfusion device
Technical field:
This utility model relates to technical field of medical instruments, refers in particular to a kind of pressure gasbag-type 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 pressure gasbag-type transfusion device by innovative technology.
For achieving the above object, this utility model adopts following technical scheme: pressure gasbag-type transfusion device, it comprises: transfusion device contact pin, upper tubing, dropping funnel, following tube for transfusion, by-pass cock and entry needle are provided with a tapered piston that can move up and down in dropping funnel inside in described dropping funnel; Be provided with a pressure air bag in described dropping funnel bottom.
Described pressure air bag is spherical in shape.
Described pressure air bag ovalize.
Described pressure air bag is cylindrical.
Described pressure air bag and transfusion device are arranged under the dropping funnel one-body moldedly.
Described pressure air bag is located away from the molding of transfusion device independence.
The beneficial effects of the utility model are: adopted to include transfusion device contact pin, air inlet pipe, upper tubing, dropping funnel, following tube for transfusion, by-pass cock and entry needle, be provided with a tapered piston that can move up and down in dropping funnel inside in described dropping funnel; Be provided with the transfusion device of a kind of like this uniqueness of a pressure air bag in described dropping funnel bottom, 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 a structural representation of the present utility model.
The specific embodiment:
See accompanying drawing 1; Pressure gasbag-type transfusion device, it comprises: transfusion device contact pin 1, upper tubing 2, dropping funnel 3, following tube for transfusion 4, by-pass cock 5 and entry needle 6 are provided with a tapered piston 7 that can move up and down in dropping funnel 3 inside in described dropping funnel 3; Be provided with a pressure air bag 8 in described dropping funnel 3 bottoms, when not using this transfusion device, tapered piston 7 rests on the bottom of dropping funnel 3, when infusing, at first push and be located at dropping funnel 3 to patient, this moment, medicinal liquid began to enter dropping funnel 3, and then squeeze pressure air bag 8 makes its pressure that produces force the tapered piston 7 of dropping funnel 3 bottoms to raise to dropping funnel 3 tops, by after medical personnel's aerofluxus the patient being infused.In the infusion process, described tapered piston 7 rests on dropping funnel 3 tops and does not influence normally carrying out of transfusion, and when transfusion is finished, 7 of the tapered pistons liquid outlet that the bottom of residual titration bucket 3 closely cooperates with it mutually with dropping funnel 3 that falls seals, 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 8 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.
Described pressure air bag 8 can be done globulate, ellipse, cylindrical or other shape according to the needs of practical situation.
Described pressure air bag 8 is arranged under the dropping funnel 3 with transfusion device is one-body molded, also can be located away from the molding of transfusion device independence, like this can be at any time according to the needs decision of practical situation whether pressure air bag 8 be set on transfusion device.
Pressure air bag 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.
