Pump-action device, include catch bar, cock body, motor 10, driving gear 4, driven gear 3 and the protuberance be fixed on away from the center of circle on driven gear 3, described protuberance is be fixed in first protuberance 8 in driven gear 3 front and be fixed in second protuberance 11 at the driven gear back side, described first protuberance 8 and the second protuberance 11 positioned opposite at the tow sides of driven gear 3, described cock body is the first cock body 6 and the second cock body 13, described cock body and connected chamber close fit and can horizontally slip in connected chamber, described catch bar is the first catch bar and the second catch bar, one end of first catch bar and the first protuberance are rotationally connected and the other end and the first cock body are rotationally connected, one end of second catch bar and the second protuberance are rotationally connected and the other end and the second cock body are rotationally connected, described driving gear is driven by motor and engages with driven gear.
On the basis of technique scheme, described infusion pump in medical application also comprises mainboard, data module, liquid crystal operation display, and described mainboard is electrically connected with single-chip microcomputer, and described motor is electrically connected with mainboard.
On the basis of technique scheme, described infusion pump in medical application has the transparent outer cover of observable internal operations.
This utility model tool has the following advantages: two cock bodys be mounted opposite on a gear, the reciprocating-piston that can hocket with the rotation of gear moves, reach the carrying out of not interrupting flow velocity to infuse, and can adjust amount of infusion on this basis, have at short notice repeatedly adjust infusion rate and do not interrupt infuse effect.
Accompanying drawing explanation
Fig. 1 is the inner pump-action device sectional view of this utility model;
Fig. 2 is this utility model internal circuit configuration figure;
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, explanation is further expalined to this utility model:
As depicted in figs. 1 and 2, infusion pump in medical application, is characterized in that, comprising:
Power supply 17; It is electrically connected with motor 10;
Pipeline 9, its two ends have an input port 2 and a delivery outlet 1, and the inner side of pipeline 9 has two inside deep connected chambers;
Liquid valve, it is that the first liquid valve 7 and the second liquid valve 14, first liquid valve 7 are arranged on cock body relative position with the second liquid valve 14 and are connected with pipeline 9 by spring;
Pump-action device, include catch bar 5, cock body 6, motor 10, driving gear 4, driven gear 3 and the protuberance be fixed on away from the center of circle on driven gear 3, described protuberance is be fixed in first protuberance 8 in driven gear 3 front and be fixed in second protuberance 11 at the driven gear back side, described first protuberance 8 and the second protuberance 11 positioned opposite at the tow sides of driven gear 3, described cock body is the first cock body 6 and the second cock body 13, described cock body and connected chamber close fit and can horizontally slip in connected chamber, described catch bar is the first catch bar 5 and the second catch bar 12, one end of first catch bar 5 and the first protuberance 8 are rotationally connected and the other end and the first cock body 6 are rotationally connected, one end of second catch bar 12 and the second protuberance 11 are rotationally connected and the other end and the second cock body 13 are rotationally connected, described driving gear 4 is driven by motor 10 and engages with driven gear 3.
Preferably, described infusion pump in medical application also comprises the mainboard 16, data module 15, the liquid crystal operation display 18 that are electrically connected each other, and described mainboard is electrically connected with single-chip microcomputer, and described motor 10 is electrically connected with mainboard 16.
Preferably, described infusion pump in medical application has the transparent outer cover 19 of observable internal operations.
When using this infusion pump in medical application, after input port being accessed the liquid of required input, start power supply, power supply drive motor operates, and drives driving gear to rotate, thus drives the driven gear engaged with driving gear.What the positive and negative of driven gear was relative is furnished with two protuberances, two protuberances are rotatably connected to respectively two catch bars, other one end of catch bar and cock body are rotationally connected, thus the one end that catch bar can be enable to be connected with protuberance moves in a circle around the center of circle of driven gear, formed and be similar to piston-engined pump-action device.When cock body moves to the side away from pipeline, make pipeline form vacuum and liquid is drawn into pipeline, when cock body moves to the side close to pipeline, compressed liquid, to an end motion of liquid valve, compresses liquid valve simultaneously and makes pipeline connection; When cock body moves to the direction away from pipeline again, pipeline is closed due to the elastic reaction of spring by liquid valve, complete motion of once infusing, because the two cover catch bars and two that are provided with relative on a gear overlap cock bodys, so what two cover cock bodys can replace carries out reciprocating-piston motion, and then continual transfusion can be realized, and send instruction to single-chip microcomputer by being arranged in LCD Controlling display in infusion pump, by the rotating speed of Single-chip Controlling motor, thus the flow velocity of transfusion can be controlled.
