Description

A kind of automatic exhausting anti-blood backflow medical Transfusion device

Technical field

This utility model relates to a kind of automatic exhausting anti-blood backflow medical Transfusion device.

Background technology

At present, in the time of the intravenous transfusion device transfusion, owing to store gas in tube for transfusion and the black Fei Shi pipe; The main effect of China ink Fei Shi pipe is in infusion process, to judge the flow velocity of transfusion and produce a siphonage to slow down infusion pressure, because the existence of black Fei Shi pipe, so infusion process just requires before venipuncture, to do the operation that drains air; Increased nurse's operation sequence like this; For making things convenient for nurse's operation, to this problem, Chinese patent CN1337098A and CN101940807A disclose respectively a kind of can self-bleeding transfusion device; But these two patents do not have stopping of lower end object in the real process, can't reach the meaning of real " automatically ".

Now general infusion set is after medicinal liquid flow when transfusion, and the interior medicinal liquid of transfusion device just flows down always, and medicinal liquid just stops when the gravitational equilibrium of the venous pressure of human body and transfusion device Chinese medicine; Because the diffusion of liquid, the blood in the human body is back in the conduit of transfusion device, and this phenomenon causes that not only patient's terrified and nurse spends the aerofluxus again of a lot of times; Because the forming very soon even cause phlebitic generation of thrombosis; For addressing these problems, patented product both domestic and external all has automatic solution stopping transfusion device, and principle is after medicinal liquid drips off in black Fei Shi pipe; Automatically seal the downcomer water inlet, so also can't reach the effect of blood return prevention.Based on this reason; Chinese patent CN201814935U has adopted the method for a drainage strip a spot of debris in the black Fei Shi pipe to be reached the effect of blood return prevention through the front end of the method introducing scalp acupuncture of syphon drainage; But because the design of processing technology and drainage strip is relatively more difficult; So manufacturing cost is relatively expensive, is difficult to into scale.

The specific embodiment

Shown in Fig. 1-4; The described a kind of automatic exhausting anti-blood backflow medical Transfusion device of this utility model embodiment; Comprise black Fei Shi pipe 1, said black Fei Shi manages 1 upper end and connects the bottle plug puncture unit 4 that has sheath 3 through upper conduit 2, and the right-hand member of bottle plug puncture unit 4 connects air filter 6 through communicating pipe 5; China ink Fei Shi manages 1 top and is provided with black Fei Shi pipe loam cake 7, and black Fei Shi pipe loam cake 7 is provided with injection member 8; The left side of China ink Fei Shi pipe 1 has side opening 9, is provided with air filtration film 10 in the side opening 9, and the outer edge of side opening 9 is connected with air filter cover 11; Said black Fei Shi manages 1 inside and is provided with dropper 12 and filter 13; Dropper 12 passes black Fei Shi pipe loam cake 7 and connects upper conduit 2; The two ends up and down of filter 13 are respectively equipped with filter cover 14 and filter lower cover 15, are provided with aqua storage tank 16 and solution stopping filter membrane 17 in the filter 13, and the both sides of aqua storage tank 16 are provided with water inlet 18; Aqua storage tank 16 bottoms are provided with weepage holes 19, and the lower end of weepage holes 19 is provided with solution stopping filter membrane 17; Said black Fei Shi manages 1 bottom and connects actuator 20, and actuator 20 other ends connect vein scalp acupuncture 22 through downcomer 21.

The operation principle of this utility model is: after opening sheath 3 bottle plug puncture unit 4 being inserted the medicinal liquid bottles; Air filter 6 on communicating pipe 5 makes medicinal liquid communicate with ambient atmosphere; Liquid is flowed in the black Fei Shi pipe 1 through upper conduit 2 and the black Fei Shi pipe loam cake 7 that has injection member 8 under action of gravity; Water main inlet port 18 through filter 13 gets in the filter 13 then; Because of the capillary effect of the solution stopping filter membrane 17 in the filter 13, medicinal liquid can not penetrate at once, and air is discharged through waterproofing type air filtration film 10 channels in the side opening 9 under the effect of liquid extruding current downflow in the black Fei Shi pipe 1; Until the air filtration film 10 that blocks water that covers side opening 9 to medicinal liquid, this pathway closure; Medicinal liquid has been broken through the surface tension of solution stopping filter membrane 17 under the effect of gravity then, flows into vein scalp acupuncture 22 through filter lower cover 14, downcomer 21, and the automatic vent before whole transfusion is accomplished; Sterilize then and begin puncture and infuse; Regulate transfusion speed with actuator 20; After the medicinal liquid of medicinal liquid bottle has flowed to the black Fei Shi pipe 1, when the nursing staff fails in time to change the bottle transfusion, because the surface tension of the solution stopping filter membrane 17 in the filter 13 follows the gravity of liquid to reach balance; Cause the medicinal liquid in the downcomer 21 not flow; Simultaneously the small amount of liquid in the aqua storage tank 16 of filter cover 14 is also on the solution stopping filter membrane 17 that splashes into slowly through the weepage holes filter cover 14 in 19 filter 13 in, and through downcomer 21 inflow vein scalp acupunctures 22 to human body, follow the gravity of medicinal liquid to reach new balance once more until surface tension; Reach the effect of automatic solution stopping, the debris in the aqua storage tank 16 is referred to as the blood return prevention time until the time of having flowed in addition.

During concrete the use; In the time of in medicinal liquid flows into black Fei Shi pipe 1, because stopping of solution stopping filter membrane 17 can be got rid of air in the black Fei Shi pipe 1 automatically through side opening 9; After side opening 9 is covered by medicinal liquid; Medicinal liquid is broken through the tension force of solution stopping filter membrane 17, flows directly into downcomer 21 and behind needle point, can infuse, and can reach self-bleeding effect fully like this; Because side opening 9 is tapers, and side opening 9 is bigger, and surface tension is not easy formation, and when changing bottle, owing to the existence of solution stopping filter membrane 17, medicinal liquid can continue to realize automatic vent; Empty the position in addition at the center of filter cover 14 and increased a groove that can store small amount of residual liquid; A very little weepage holes 19 is opened in the centre; Through the gravity drainage effect, a spot of debris is slowly flowed on the solution stopping filter membrane 17, until vein scalp acupuncture 22; Endovascular blood is produced a malleation, reached the real interior blood return prevention effect of certain hour.

As shown in Figure 2; China ink Fei Shi pipe 1 also can not established steam vent, only need close actuator 20 and extruded ink Fei Shi pipe 1, perhaps is inverted the mode water-retention of black Fei Shi pipe 1; Reach 1/2-2/3 position of black Fei Shi pipe 1 up to medicinal liquid; Medicinal liquid can be infused after downcomer 21 flows into vein scalp acupuncture 22 then, after medicinal liquid has flowed, can reach the effect of blood return prevention equally through blood return prevention filter 13; But when reaching blood return prevention, need close actuator 20 extruded ink Fei Shi pipe 1 when changing bottle, could guarantee that like this downcomer 21 can not produce bubble.
