Description
Technical field
This utility model relates to a kind of mechanically operated adjustable continuous micro-portable infusion device.
Background technology
The method of infusing in medical procedure at present all adopts utilizes the gravity of medicinal liquid to flow into vein by liquid-transport pipe-line in transfusion bag (bottle) drug pack.Infusion bottle or transfusion bag must be suspended on suitable height, because flow of liquid is gone into the influence that the flow of vein blood vessel will be subjected to medicinal liquid own wt and height, the flow of medicinal liquid input relies on the regulating wheel in the liquid-transport pipe-line to control.Patient must sit near drip stand and crouch during transfusion, this is very inconvenient for the people of long-time transfusion as everyone knows, along with the minimizing of liquid, small variation also will take place to transfusion bag (bottle) in the flow of input liquid, and the flow of medicinal liquid can not be controlled effectively under level altitude simultaneously.Especially sometimes because of the medicine difference, the flow that need import is also different, and transposing is got up and rather bothered, and the nurse often will by virtue of experience just can reach requirement through repeatedly debugging.The utility model proposes a kind of by the mobile transfusion device of action of mechanical pressure promotion medicinal liquid, the solution that the problems referred to above are satisfied with.
Summary of the invention
Below in conjunction with accompanying drawing structural principle of the present utility model is described.As shown in the figure, adjustable continuous micro-transfusion device comprises fixed support, gear train, clockwork spring, escapement, hairspring, transfusion catheter and medicine bottle etc.Fixed support 1 is equipped with 4 pairs of gears and constitutes gear train, and every pair of gear comprises each one of large and small gear.First couple of gear 2-1 fixes with an end of manual clockwork spring 3, and the other end is fixed in fixed support 1.The steamboat of the bull wheel of gear 2-1 and second level gear 2-2 is meshing, and the steamboat of the bull wheel of gear 2-2 and third level gear 2-3 is meshing, and the steamboat of the bull wheel of gear 2-3 and fourth stage gear 2-4 is meshing.The bull wheel of gear 2-4 is connected with escapement 5 by dibit check lever 4, and escapement 5 is coaxial fixing with an end of hairspring 6, and the other end of hairspring 6 is fixed on the fixed support 1.The rotational power of gear train and escapement provides (as Fig. 1) by manual clockwork spring 3.Rotating disk 7 is upper and lower dish structure, is provided with 4 rollers 8 between upper and lower dish.Transfusion catheter 9 is positioned at the outside of rotating disk 7 and locatees with bent plate 10, and bent plate 10 is by contact roller 11 fixing (as Fig. 2,3).This device utilizes the unisexuality of hairspring 6 to make escapement 5 do initial swing, and under hairspring and the combined effect of escapement inertia, escapement 5 is done periodic oscillations.Under the effect of escapement periodic oscillations, pass through the velocity of rotation (as Fig. 5) of dibit check lever 4 control gear groups, because upper surface and clockwork spring and the coaxial gear 12 that is equipped with of gear 2-1 at fixed support 1, finger 13 (as Fig. 4) is housed on the chassis of rotating disk 7, so when the effect lower tooth wheels of clockwork spring rotate release clockwork spring energy, drive rotating disk 7 by the effect of gear 12 and finger 13 and rotate, rotating disk 7 drives four rolling 8 thereupon and rotates and push liquid with this and discharge from transfusion catheter 9.The adjusting of fluid flow is by changing the transfusion catheter 9 of different tube diameters, and the caliber scope of transfusion catheter 9 is 2～5mm.Bent plate 10, contact roller 11 and rotation display 14 place the upper surface of fixed support 1, rotate display 14 and are connected with gear 2-4 is coaxial.One end of transfusion catheter 8 links to each other with medicine bottle 15, and the transfusion catheter other end links to each other with infusion needle.For preventing that tube for transfusion from moving, be provided with fixing card 16 in fixed support 1 upper surface fixing with transfusion catheter 9.

The specific embodiment
Below by specific embodiment to this utility model do one the step explanation.Accompanying drawing is assembled each parts to specifications.Fixed support 1 is equipped with 4 pairs of gears and constitutes gear train except that escapement 5, and every pair of gear comprises each one of large and small gear, and the gear ratio of big pinion is 20: 1.The rotational power of gear train and escapement is provided by manual clockwork spring 3, tightens clockwork spring by knob 17, and upward expiring behind the clockwork spring can continuous operation 24 hours.This machine driving has been utilized the clock and watch drive mechanism, and dibit check lever 4 by the transmission speed (as Fig. 5) of check lever 4 control gear groups, thereby makes the velocity of rotation of roller 8 constant under the effect of escapement 5 periodic oscillations.During use transfusion catheter 9 is placed the outside of rotating disk 7 four rollings 8, bent plate is fixed and clamped by bent plate 10 location and by the position of adjusting contact roller 11.Rotational power drive rotating disk 7 by escapement and gear train carries out slight rotation, and the four rolling in the rotating disk 7 will roll on transfusion catheter thereupon, thus liquid continuous " squeezing " is gone out.According to depending on actual need, the control of medicinal liquid flow size can be changed the transfusion catheter of different-diameter, also can finely tune the rotating speed of gear by adjusting hairspring.The caliber scope of transfusion catheter 9 is 2～5mm, is 3mm to the caliber of present embodiment transfusion catheter.Fixed support is put into special-purpose instrument box together with medicine bottle integral body, and the overall volume of instrument box is 130mm (length) * 80mm (wide) * 50mm (height).The position of instrument box can arbitrarily be placed and do not influenced the output of liquid.When rotating, gear train work can observe the demonstration of rotating display 14 by viewing window.
The utility model beneficial effect is: the liquid of realizing adjustable continuous micro take clockwork spring as power is carried infusion bag Putting position be not subjected to constraint, and the stability of flow carried of liquid. The utility model does not need driven by power, knot Structure is simple, except using as also can be used as a kind of desirable Miniature liquid pump at other numerous areas medical.
