Abstract
A rotation stopper capable of eliminating vortex generated when an infusion pump draws liquid during preparation of large infusion. It is composed of a disc of a rotation stopping device and a damping frame at the top of the disc. When the infusion pump draws liquid to generate the vortex, the vortex stopper can prevent the vortex from extending and eliminate the influence of the vortex. Can ensure the smooth operation when preparing the infusion solution and improve the filtering quality.
Description
The utility model is a kind of device that produces vortex in the medical industry production that is used for eliminating.When it can be to pressure filtration because effect is revolved in the vortex start-stop that produces during the infusion pump drawing liquid.
The vortex that produces when at present, infusion pump being extracted soup does not still have good removing method.Because its draft is bigger, and water outlet is less, the impact effect of the soup that in addition refluxes makes soup constantly rotation in mixer when infusion pump extracts soup, when soup be evacuated to mixer half when following, even more serious.Because the rotation of mixer inner liquid medicine forms vortex and causes a large amount of air admissions, the filter pressure rapid drawdown has influenced filter quality, when serious can can't be carried out smoothly.
The purpose of this utility model provides a kind of, can eliminate the vortex that produces when infusion pump extracts soup, can be carried out smoothly, and actv. improves the filter quality and the work efficiency of infusion solutions.
The purpose of this utility model is achieved in that rotation-stop device is made up of the rotation-stop device disk (edge has radian slightly) and the damping frame at disk top.During use rotation-stop device is placed in the exit in the mixer, and fixed.The vortex that the rotation-stop device disk produces in the time of can stoping infusion pump to extract soup extends to the mixer exit, and damping frame has played shock damping action to the rotation of vortex, makes the velocity of rotation reduction of vortex and is tending towards disappearance.Avoided air to enter infusion pump by water outlet.
Owing to adopt such scheme, can eliminate the vortex that produces when infusion pump extracts soup, improved filter quality and work efficiency.It is simple in structure, and is easy to use.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the riding position figure of rotation-stop device.
Fig. 2 is that the rotation-stop device block diagram can be made the specification digest accompanying drawing
Fig. 3 is the rotation-stop device birds-eye view.
Fig. 4 is the rotation-stop device section-drawing.
Among the figure 1, mixer 2, damping frame 3, rotation-stop device disk 4, water outlet
The criss-cross damping frame (2) that rotation-stop device has the rotation-stop device disk (3) of radian slightly by the edge and is welded on rotation-stop device disk (3) top among the figure is formed.The high 20mm in centre of criss-cross damping frame (2), each top, end top is the obtuse angle, its below coincide with the radian on rotation-stop device disk (3) top, each end that grows rotation-stop device disk (3) is respectively than the high 5mm in edge of rotation-stop device disk (3), and it is identical with the radian at mixer (1) end, as fulcrum, make the edge of rotation-stop device disk (3) and mixer (1) end that certain clearance be arranged.The length of the diameter of rotation-stop device disk (3) and damping frame (2) should be according to the decision of the diameter of mixer, is example with the mixer of diameter 1000mm, and rotation-stop device disk (3) diameter is 200mm, and damping frame length is 300mm.Being fixed in water outlet (4) during use locates.The vortex that produces when the infusion pump drawing liquid, rotation-stop device disk (3) can stop it to extend to water outlet (4), and damping frame (2) plays shock damping action to the rotation of vortex, make the rotative speed reduction of vortex and are tending towards disappearance.Because the fulcrum of damping frame (2) makes the rotation-stop device disk (3) and mixer (1) end that certain clearance be arranged, and makes liquid enter water outlet (4) from here.
The utility model is novel, and is rational in infrastructure, convenient and practical, is convenient to make.Being applicable to that hospital, pharmaceutical factory prepare when infusion solutions and other industry extract liquid with water pump from container uses.
Claims (4)
1, a kind of infusion pump drawing liquid rotation-stop device that produces vortex can eliminate the infusion pump drawing liquid time, it is characterized in that rotation-stop device disk (3) is welded on the damping frame (2) on rotation-stop device disk (3) top with it, each end with damping frame (2) is a fulcrum, makes the rotation-stop device disk (3) and mixer (1) end that certain clearance be arranged.
2,, it is characterized in that rotation-stop device disk (3) edge has radian slightly according to the described device of claim 1.
3, according to the described device of claim 1, the damping frame (2) of high 20mm in the middle of it is characterized in that, each top, end top is the obtuse angle, the radian on below and rotation-stop device disk (3) top coincide.
4,, it is characterized in that each end that damping frame (2) grows rotation-stop device disk (3) respectively than the high 5mm in edge of rotation-stop device disk (3), and coincide with the radian at mixer (1) end according to claim 1,3 described devices.
