Abstract
The utility model relates to a medical transfusion device, in particular to a cam type transfusion system using a cam mechanism to drive a set of movable sheets to squeeze a transfusion tube in order to cause liquid in the transfusion tube to move forwards orderly for obtaining the aim of transfusion. The transfusion tube (13) of the cam type transfusion system is arranged at one side of the movable sheets (7) which can move up and down orderly. The movement of the movable sheets (7) is transferred for pin joint via a motor (1), a ratio wheel unit, a cam unit and a driven assembly. The cam unit and the driven assembly are arranged on machine bases (8, 9), and the machine bases are arranged in a machine shell (15); the motor and the ratio wheel unit are arranged out of the machine shell (15), and the upper part of the machine shell (15) is provided with a cover board (14). The cam type transfusion system has reasonable structure, reliable performance and simple operation.
Description
Technical field
This utility model relates to medical infusion set, refers in particular to utilize cam mechanism to drive one group of moving plate extruding tube for transfusion, the liquid that makes tube for transfusion in order forward wriggling reach the cam type infusion device of transfusion purpose.
Background technology
Clinically, venous transfusion is a kind of widely used medical skill, but traditional infusion model, is the speed of dripping of examining dropper with observing, manually adjust the degree of tightness that tube for transfusion is clipped on the flexible pipe and guard whole infusion process, and not only waste of manpower, but also loaded down with trivial details, and efficient is low.In recent years, for improving this situation, existing transfusion control device occurs in succession as a drip apparatus, automatic infusion pump, positive effect has been played in the nursing that improves transfusion, but the mode of bent axle and revolving transfusion, its cost is higher, or noise is bigger, and the risk that drags and squeeze brokenly tube for transfusion is arranged, directly influenced the effect of transfusion.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of cam type infusion device is provided.
The purpose of this utility model is finished with following technical scheme: tube for transfusion is placed one group of side of the moving plate of knee-action successively, wherein the motion of moving plate is to be articulated by motor, deceleration wheels, cam set, driven subassembly transmission, described cam set and driven subassembly are arranged on the support, support is arranged in the casing, motor and deceleration wheels are located at outside the casing, and casing top is provided with cover plate.
This utility model pushes deformable tube for transfusion successively by the one group of eccentric cam that rotates under the driving of motor, liquid is exerted pressure, and to overcome resistance, reaches the purpose of transfusion.This utility model is rational in infrastructure, and dependable performance is simple to operate.

The specific embodiment
By Fig. 1,4 as can be known, this utility model places one group of side of the moving plate of knee-action (7) successively with tube for transfusion (13), wherein the motion of moving plate (7) is to be articulated by motor (1), deceleration wheels, cam set, driven subassembly transmission, described cam set and driven subassembly are arranged on the support (8,9), support is arranged in the casing (15), motor and deceleration wheels are located at outside the casing (15), and casing (15) top is provided with cover plate (14).
Motor described in the utility model (1) is located at the outer side of casing (15) by motor cabinet (17), and the deceleration wheels are made up of by the one synchronous belt wheel (4) of band (3) pivot joint synchronously a driving wheel (2), and synchronous pulley (4) articulates main shaft (5).Each cam (6) is axially being spent angular distribution arrangement by 60 separately in the described cam set.Described driven subassembly comprises driven pulley (12), follower lever (10), back-moving spring (11) and moving plate (7), and wherein driven pulley (12) is embedded in follower lever (10) top, and follower lever (10) epimere is provided with back-moving spring (11), and the bottom is provided with moving plate (7).Described support (8) is provided with one group of locating slot (81), and moving plate (7) is located in the locating slot (81), and support (9) is provided with one group of pilot hole (91), and follower lever (10) telescopically is located in the pilot hole (91).Described support (8) is positive to be provided with transfusion pipe clamp (18) along tube for transfusion (13) direction, and tube for transfusion (13) is clamped in the transfusion pipe clamp (18).Described cover plate (14) is connected on the casing (15) with hinge, and cover plate (14) inner face lays with sheet rubber (16), and cover plate (14) is shut the backing plate into tube for transfusion (13).
Operation principle of the present utility model: this utility model has 12 cams and forms cam set, each cam all is fixed on the axle by the order axially spaced-apart at 60 degree angles, when main axis rotation, can guarantee that each cam does the extruding action to the spacing that corresponding moving plate separately moves on request.Extruding puts in place to tube for transfusion in order to make the moving plate uniform motion and to guarantee to have all the time two moving plates, and each moving plate is by the periphery of axially respectively making 61 degree.Moving plate stretches inside and outside the locating slot of support according to the progress of distributing separately.In order to reduce cam friction to moving plate when rotating, in the upper end of double-action plate one driven pulley is installed, below driven pulley, a return spring that is clipped between moving plate and the support is arranged, cam is in when bearing periphery, can guarantee the timely return of moving plate.Tube for transfusion accompanies two, is fixed on the front of support, and it is made by an elastoplast, and tube for transfusion is clamped in wherein.Cover plate is bound up on the casing with hinge, and the one side in the cover plate is laid with sheet rubber,, shuts at cover plate the excessive compression of tube for transfusion and the inequality of pressure with the buffering moving plate, have on the automatic kayser after, just make the backing plate of tube for transfusion.
