Fig. 2 is the structural representation of the transfusion device of the band degassing function of another embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, this utility model is described in further detail.
Embodiment one
See Fig. 1, this utility model provides a kind of transfusion device with degassing function, and this transfusion device comprises dropper 1, the tube for transfusion 2 being communicated with dropper 1 and the actuator 3 be placed on tube for transfusion 2.Wherein, tube for transfusion 2 is provided with exhaust apparatus 4, and this actuator 3 is placed between dropper 1 and exhaust apparatus 4.Exhaust apparatus 4 comprises discharge chamber 41, and discharge chamber 41 is communicated with tube for transfusion 2.
In the present embodiment, discharge chamber 41 two ends are communicated with tube for transfusion 2, and the tube for transfusion 2 that exhaust apparatus 4 is connected with patient is provided with the first control and presss from both sides 5.Better can control bleeding thus, when needs aerofluxus, the first control folder 5 can be closed, control bubble and move towards the direction of dropper 2 and be discharged.
In the present embodiment, the diameter of section at the middle part of discharge chamber 41 is greater than the diameter of tube for transfusion 2, and this discharge chamber 41 can be elliposoidal, circle or other similar cavity geometries.The material of discharge chamber 41 is elastomeric material.This elastomeric material can be polrvinyl chloride, polyethylene, polypropylene or poly vinyl acetate material, also can be thermoplastic elastomer (TPE), as TPO etc.So, because discharge chamber 41 is elastomeric material, can better crimp and fast quick-recovery, be that the liquid carrying of the bubbles in extruding tube for transfusion 2 is for better motive force.
In the present embodiment, the two ends of this discharge chamber 41 are communicated with tube for transfusion 2 respectively.Discharge chamber 41 can first independent molding, then is bondd as a whole by Joining Technology with tube for transfusion 2; Discharge chamber 41 also can be formed with tube for transfusion 2 one.
In the present embodiment, discharge chamber 41 can be communicated with exhaustor 43.So, owing to adding exhaustor 43, the exhaust effect of exhaust apparatus 4 can be increased further.
In the present embodiment, the lower end in dropper 1 can be provided with defecator 11.In present embodiment, this defecator 11 is filter bag.In other embodiments, this defecator 11 also can be filter membrane or drainage screen or other defecators.Thus, the impurity in loading liquid can be removed, avoid causing untoward reaction.
In the present embodiment, exhaust apparatus 4 is 5 ~ 20cm apart from tube for transfusion 2 near the end of patient.Optionally, exhaust apparatus 4 is located apart from tube for transfusion 2 end about 10cm.So, when in infusion bottle, liquid drips off, air can enter tube for transfusion 2 li and slowly decline, but due to the pressure of venous patient blood itself, the fluid level declined in tube for transfusion 2 can at least stop higher than transfusion vein plane 20-30cm place, if exhaust apparatus 4 is placed in distance tube for transfusion 2 end about 5 ~ 20cm, can ensures not enter air in exhaust apparatus 4, can effectively stop and slow down the generation of blood back phenomenon.
The transfusion device of the band degassing function that present embodiment provides, in actual clinical transfusion, when there is bubble in tube for transfusion 2, the operating procedure of deaeration: when there is bubble in tube for transfusion 2, after first cut out first control folder 5 is fastening, then extrude discharge chamber 41, make the liquid of bubbles move to rapidly dropper 1, finally slowly unclamp discharge chamber 41, so repeatedly several times in tube for transfusion 2 till bubble collapse.After air drains, the first control folder 5 can be opened, continue normal infusion.
Embodiment two
Be another embodiment of this utility model see Fig. 2, Fig. 2.The difference of present embodiment and embodiment one is: in present embodiment, and exhaust apparatus 4 also comprises connection tube 42, and the Single port of connection tube 42 is communicated with discharge chamber 41, and another port is communicated with tube for transfusion 2.So, owing to increasing connection tube 42, one is convenient to processing and fabricating; Two carry out discharge chamber 41 can control separately, uses flexible operation.
In the present embodiment, port connection tube 42 being communicated with tube for transfusion 2 can be provided with the second control folder 44, and this second number controlling folder 44 is one.Thus, better can control aerofluxus, when without the need to aerofluxus, can close the second control folder 44, the use operating procedure of tube for transfusion 2 is the same with common transfusion pipe, facilitates medical worker to use; And when needs aerofluxus, then can open the second control folder 44 and be exhausted operation.In the present embodiment, in order to improve the exhaust efficiency of exhaust apparatus 4, the caliber that connection tube 42 is connected with tube for transfusion 2 is greater than the caliber of tube for transfusion 2.In addition, in the present embodiment, owing to employing the second control folder 44, the first control folder 5 be similar in embodiment one can be omitted.
The transfusion device of the band degassing function that present embodiment provides, in actual clinical transfusion, the operating procedure of deaeration: this transfusion device is when just bringing into use, first can control folder 44 with second and be fixedly connected with pipe 42, now this transfusion device equally can use, without the need to being additionally exhausted discharge chamber 41 as general infusion set.When there is bubble in tube for transfusion 2, open the second control folder 44, by extruding discharge chamber 41, deaeration, after air drains, can close the second control folder 44, continue normal infusion.
Other guide in present embodiment also see embodiment one, can not repeat at this.
The transfusion device of band degassing function provided by the utility model, this transfusion device not only structure is simple, easy to operate, safe and reliable, can fast and effectively by clean for the removal of bubbles in tube for transfusion 2.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from this utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
