Abstract
The utility model belongs to medical equipment, and relates to an infusion regulator for regulating the flow rate of an infusion apparatus or an analgesia infusion apparatus. It includes a fixed pedestal and a rotatory overcoat, installs a plurality of branch's transfer line on fixed pedestal, has concatenated the flow controller on every branch transfer line, and the both ends of each branch transfer line are led to the parallelly connected between total feed liquor pipe and total drain pipe through two multipaths, the external diameter of fixed pedestal root and the internal diameter normal running fit of rotatory overcoat, the external diameter of fixed pedestal anterior segment is less than its root, each branch transfer line all has one section part through fixed pedestal anterior segment, and this part evenly distributed is peripheral at the half circumference of fixed pedestal anterior segment, and is corresponding with it, has a bellied semicircular rib on the half circumference of inner wall of rotatory overcoat. The utility model has the advantages that: simple structure, convenient operation, regulation precision height.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of infusion regulator that transfusion device or analgesia impregnator flow velocity are regulated of being used for.
Background technology
At present, be used for patient's back analgesic analgesia impregnator of performing the operation, its flow velocity generally is fixed, can't regulate, and when needs change flow velocity, need change apparatus again, and it is very inconvenient to use; And be used for the transfusion device of venous transfusion, though simple adjusting device (as roller switch) is arranged, its degree of regulation is very poor, is difficult to the occasion that is applicable to that ask for something is higher.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of simple in structure, easy to operate, infusion regulator that degree of regulation is high is provided.
Infusion regulator of the present utility model comprises a fixed base frame and a rotary sleeve, some branch's tube for transfusions are installed on fixed base frame, be serially connected with reducer on every branch's tube for transfusion, the two ends of each branch's tube for transfusion are by logical being connected in parallel between total feed tube and the main drain pipe more than two, the external diameter of described fixed base frame root and the internal diameter of rotary sleeve are rotatably assorted, the external diameter of fixed base frame leading portion is less than its root, described each branch's tube for transfusion all has one section part through the fixed base frame leading portion, this part is evenly distributed on half periphery of fixed base frame leading portion, corresponding with it, the semi-circular rib that a projection is arranged on half circumference of inwall of rotary sleeve, when semi-circular rib is positioned at identical semi-circumference with branch's tube for transfusion of fixed base frame periphery, rib will push branch's tube for transfusion, and close the transfusion path of one or more branch's tube for transfusion.Described branch tube for transfusion can be located on fixed base frame in the following way, promptly at the root of fixed base frame, evenly has several axial through holes on half circumference at its edge, is installed with branch's tube for transfusion in each through hole.
This utility model is controlled the number that branch's tube for transfusion is switched on and closes by changing the relative rotation angle of rotary sleeve and fixed base frame, can reach the purpose of accurate adjustment infusion flow rate, and its adjustment is easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end face structure sketch map of fixed base frame;
Fig. 3 is the cross section structure sketch map of rotary sleeve.
The specific embodiment
As shown in the figure, infusion regulator comprises a fixed base frame 1 and a rotary sleeve 2, some branch's tube for transfusions 3 are installed on fixed base frame, be serially connected with reducer 4 on every branch's tube for transfusion, to set the flow velocity of every branch's tube for transfusion, the two ends of each branch's tube for transfusion are connected in parallel between total feed tube 6 and the main drain pipe 7 by leading to 5 two more, and whole infusion regulator can be serially connected in the infusion pipeline of intravenous transfusion device or analgesia impregnator by total feed tube 6 and main drain pipe 7.The external diameter of fixed base frame root and the internal diameter of rotary sleeve are rotatably assorted, the external diameter of fixed base frame leading portion 8 is less than its root, each branch's tube for transfusion 3 all has one section part through fixed base frame leading portion 8, and this part is evenly distributed on half periphery of fixed base frame leading portion 8.Corresponding with it, the semi-circular rib 9 that a projection is arranged on half circumference of inwall of rotary sleeve 2, when rotating rotary sleeve, when making semi-circular rib enter in the residing semi-circumference of branch's tube for transfusion, rib will push branch's tube for transfusion successively, the transfusion path of one or more branch's tube for transfusion is closed, and the quantity of closing is determined by the angle of rotation.The locate mode of branch's tube for transfusion 3 on fixed base frame 1 is evenly to have several axial through holes 10 on half circumference of the root edges of fixed base frame, is installed with branch's tube for transfusion in each through hole 10.
Claims (2)
1, a kind of infusion regulator, it is characterized in that: it comprises a fixed base frame (1) and a rotary sleeve (2), some branch's tube for transfusions (3) are installed on fixed base frame, be serially connected with reducer (4) on every branch's tube for transfusion, the two ends of each branch's tube for transfusion are connected in parallel between total feed tube (6) and the main drain pipe (7) by logical (5) more than two, the external diameter of described fixed base frame root and the internal diameter of rotary sleeve are rotatably assorted, the external diameter of fixed base frame leading portion (8) is less than its root, each branch's tube for transfusion (3) all has one section part through fixed base frame leading portion (8), this part is evenly distributed on half periphery of fixed base frame leading portion (8), corresponding with it, the semi-circular rib (9) of a projection is arranged on half circumference of inwall of rotary sleeve (2).
2, infusion regulator according to claim 1 is characterized in that: evenly have several axial through holes (10) on half circumference of the root edges of fixed base frame, be installed with branch's tube for transfusion (3) in each through hole.
