Abstract
The utility model relates to an infusion tube wall thickness compensation device of an infusion pump. The infusion tube wall thickness compensation device comprises a power mechanism and an infusion pump door, wherein the power mechanism comprises a cam shaft, bearings are installed at the two ends of the cam shaft, a first cam group and a second cam group are installed in the middle of the cam shaft, the first cam group is used for controlling a first closing valve and a first extruding sheet, and the second cam group is used for controlling a second closing valve and a second extruding sheet; and the infusion pump door comprises a guide plate, a stress column which is sheathed on the guide plate, a buffer spring and a supporting plate which is used for supporting the spring. By compensating the wall thickness of an infusion tube through the structure on the infusion pump door, the infusion tube wall thickness compensation device of the infusion pump is enabled to be applicable to various infusion methods by using infusion tubes with different tube diameters.
Description
Technical field
This utility model relates to the tube for transfusion wall thickness compensation arrangement of a kind of compensation arrangement, particularly a kind of infusion pump.
Background technology
The tradition infusion is utilize the gravity of liquid to do power, and patient is carried out venous transfusion.This infusion model is difficult to control steadily in the long term transfusion speed and amount of infusion, and the high or strict occasion of controlling transfusion speed and amount of infusion of needs, be difficult to meet the demands for the ask for something precision.Perhaps, the compensation arrangement of a lot of infusion sets can be arranged on body interior, can cause like this and safeguard inconvenience, and mode is difficult, thereby after life-time service, the dirt that inside produces is difficult to process so that affect the performance of compensation arrangement, causes precise decreasing even can't use.
The utility model content
A kind of tube for transfusion wall thickness compensation arrangement of infusion pump, comprise actuating unit, infusion pump door, wherein: described actuating unit comprises camshaft, bearing, the first cam set, the second cam set, the first sealing valve block, the second sealing valve block, the first extruding plate and the second extruding plate, bearing is arranged on the two ends of camshaft, the centre is equipped with the first cam set and the second cam set from top to bottom, and controls respectively the first sealing valve block, the first extruding plate and the second sealing valve block, the second extruding plate; Described infusion pump door comprises guide plate and is set with superincumbent force column, and the force column back is over against filling the buffer spring that is supported on gripper shoe.
As further improvement of the utility model: have cam hole on described the second sealing valve block.
As further improvement of the utility model: the centrage of described the first sealing valve block and the second sealing valve block all with the axis conllinear of force column.
As further improvement of the utility model: described buffer spring and force column are coaxial.
Compared with prior art, the beneficial effects of the utility model are: compensation mechanism is directly installed on infusion pump door simple in structure, and is easy to maintenance, and it is convenient to regulate, the dirt that in use produces in inside is easy to cleaning, thereby guarantees transfusion precision of the present utility model and service life.
Description of drawings
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the A-A profile.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Referring to figs. 1 through Fig. 2, a kind of tube for transfusion wall thickness compensation arrangement of infusion pump, comprise actuating unit 1, infusion pump door 10, wherein: described actuating unit 1 comprises camshaft 5, bearing 2, the first cam set 3, the second cam set 4, the first sealing valve block 9, the second sealing valve block 6, the first extruding plate 8 and the second extruding plate 7, bearing 2 is arranged on the two ends of camshaft 5, the centre is equipped with the first cam set 3 and the second cam set 4 from top to bottom, and controls respectively the first sealing valve block 9, the first extruding plate 8 and the second sealing valve block 6, the second extruding plate 7; Described infusion pump door 2 comprises guide plate 12 and is set with superincumbent force column 14, and force column 14 back are over against filling the buffer spring 13 that is supported on gripper shoe 15.
The cam that described the second sealing has cam hole 17, the second cam set 4 on valve block 6 is packed into and is used for controlling the first sealing valve block 9 actions in cam hole 17.
Described the second sealing valve block 6 and the first sealing valve block 9 have same structure.
Described the first cam set 3 and described the second cam set 4 certain angle that staggers when mounted, thus dress liquid formed, and as long as the tapping alternating movement is the velocity of rotation of adjustment cam axle 5 just scalable transfusion speed and amount of infusion.
The centrage of described the first sealing valve block 9 and the second sealing valve block 6 all with the axis conllinear of force column 14, in order to the wall thickness compensation is carried out in the transfusion of difference transfusion caliber, improve sealing effect, thereby allow all relatively more thorough transfusion precision that improved of dress liquid and tapping.
Described buffer spring 13 and force column 14 are coaxial, thereby guarantee that buffer spring 13 in use can not cause sealing effect to reduce impact transfusion precision because unbalance stress produces dislocation.
In use, camshaft 5 rotates, when the first sealing valve block 9 and the first extruding plate 8 pushed down tube for transfusion 11, tube for transfusion 11 is in the dress liquid status, liquid enters and fills liquid zone 16, because tube for transfusion 11 is crushed to death, so the dress liquid zone 16 quantitative liquid can be housed, when camshaft 5 continues to turn over an angle again, the second sealing valve block 6 can kill tube for transfusion 11, liquid no longer flows into and fills in liquid zone 16, and when the first sealing valve block 9 and the first extruding plate 8 are opened, the second extruding plate 7 extrudes the quantitative liquid that fills liquid zone 16, thereby realizes the function of quantitative transfusion; If when changing the tube for transfusion 11 of different tube diameters, because force column 14 can be elastic, can adapt to different tube for transfusion wall thickness, can realize above function equally.
In sum; after those of ordinary skill in the art reads this utility model file; need not creative mental work according to the technical solution of the utility model and technical conceive and make other various corresponding conversion scheme, all belong to the scope that this utility model is protected.
