Description
Technical field
This utility model relates to a kind of intravenous transfusion device, is specifically related to a kind of flow regulator of intravenous transfusion device.
Background technology
The intravenous transfusion device flow regulator of at present common stability of flow is the roller type by-pass cock, is made of the framework of being with skewed slot and the roller that is located at the skewed slot top, and the tube for transfusion of transfusion device is arranged between skewed slot and the roller; By scroll wheel, regulate the distance between idler wheel bottom and the skewed slot ground, reach the purpose of effective transfusion caliber of regulating tube for transfusion, thereby regulate transfusion speed.But the adjustment precision of this flow regulator is not high enough.For solving this technical problem, Granted publication number a kind of for the utility model patent of CN 201147545Y discloses " easily speed governing transfusion device ", it is characterized in that it comprises two roller type by-pass cockes, the gradient difference of the skewed slot of these two speed-regulating switch kind frameworks, what wherein gradient was bigger is the coarse adjustment switch, and gradient smaller is an inching switch.This patent scheme has improved the degree of accuracy of speed governing by the combination of coarse adjustment and fine setting.But above-mentioned two kinds of flow regulators all utilize roller extruding tube for transfusion, and then change the caliber of tube for transfusion, reach the purpose of regulating flow.Therefore, a lot of unexpected factors can cause roller to produce displacement in infusion process, and as rocking of tube for transfusion, the variation of ambient temperature causes the coefficient of elasticity of tube for transfusion to become big or the like.These accidentalia usually cause the roller change in location, cause the infusion flow instability.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of intravenous transfusion device flow regulator, and this device has the advantage of stability of flow.
The technical scheme that this utility model addresses the above problem is:
A kind of intravenous transfusion device flow regulator of stability of flow is characterized in that, it is made up of the rotating disk of up and down coaxial setting and price fixing and detent mechanism, wherein,
Be evenly equipped with some radial transfusion runners of arranging in turn according to pore size in the body of price fixing, the import of every transfusion runner is located at the upper surface of price fixing and lays respectively at the axial line is on the circumference in the center of circle, and the outlet of every transfusion runner comes together in the lower surface of price fixing;
Be provided with a transfusion in the body of rotating disk and distribute runner, this transfusion distributes the import of runner to be positioned at the center of rotating disk upper surface, exports to be positioned on the rotating disk lower surface and to exist together on the circumference with the import of described transfusion runner; Described transfusion distributes the aperture of runner to be not less than the aperture of the transfusion runner of aperture maximum;
Described detent mechanism is: being respectively equipped with between the lower surface of described rotating disk and the price fixing upper surface with the two axial line is the circular groove that cooperatively interacts and the circular protrusions in the center of circle, the periphery of described circular protrusions is provided with annular gathering sill, and bottom land is provided with recess in the import department corresponding to described transfusion runner; At least be evenly equipped with the alignment pin that three heads and described recess are complementary on the inner headed face of described circular groove in the corresponding position of annular gathering sill, wherein have the position of an alignment pin to distribute the outlet of runner corresponding with described transfusion, the afterbody of self-align pin outwards is provided with spring and plug screw successively in the installing hole of each alignment pin.
The intravenous transfusion device flow regulator of a kind of stability of flow described in the utility model, wherein, import department at the transfusion runner on the periphery of described price fixing is respectively equipped with graduation mark, distributes the corresponding position of runner exit to be provided with indicatrix in transfusion on the periphery of rotating disk.
The intravenous transfusion device flow regulator of a kind of stability of flow described in the utility model, wherein, the periphery of described rotating disk or price fixing is provided with the arrow that points to the ascending direction of transfusion flow passage aperture.
The intravenous transfusion device flow regulator of stability of flow described in the utility model, wherein said detent mechanism are a kind of pin detent mechanism, tube for transfusion rock and the change of the coefficient of elasticity of tube for transfusion all can not gently be anticipated and changed the relative position of rotating disk and price fixing.When therefore using, medical worker's advanced row coarse adjustment is according to circumstances promptly rotated rotating disk and is selected suitable transfusion runner, and then the height of adjustment liquid medicine bottle is finely tuned, can not change in case infusion flow just configures, unique factor that can cause that infusion flow changes has only liquid level variation in the liquid medicine bottle.But the people of tool general knowledge knows slightly, and liquid level variation causes that the variation of infusion flow is small and slowly in the liquid medicine bottle, and only understands linearity and diminish, and is can portion not big, can not cause in infusion process therefore that the patient's is uncomfortable because of the variation of flow.
