Abstract

The utility model relates to a pointer type controllable micro-flow transfusion system which consists of a box body, a valve core and a knob, and is characterized in that a run-through hole (2) is arranged at the lower part of the box body (1), a valve core chamber (4) is arranged above the hole, the valve core (5) is arranged in the valve core chamber, a screw rod (6) is arranged at the upper end of the valve core, the knob with internal threads is arranged on the screw rod, a pointer (9) is fixedly arranged on the screw rod, and scales (10) are manufactured on the surface of the box body. In the utility model, the disadvantages of the current transfusion system are overcome, and the pointer type controllable micro-flow transfusion system has the advantages that flow rate can be directly displayed through the pointer, the pointer type controllable micro-flow transfusion system is convenient and safe in use, the transfusion speed can be micro-regulated, the production process and the structure are simple, the cost is low and asepsis principle can be kept and the like.

Description

The controlled micrometeor transfusion device of pointer-type

Technical field

This utility model relates to the medical infusion field, but the transfusion device of a kind of more precisely pointer-type micrometeor regulation and control.

Background technology

Transfusion is one of conventional medical procedure, in treatment clinical course, control for transfusion speed is important, the input speed of a lot of patients' all strict control intravenous fluids of the state of an illness, particularly for the baby, the children, the child, the relatively poor patient of old people and cardiac function more should note the speed of venous transfusion, do not note slightly just acute heart failure may occurring, even cause death, at present, the many employings of hospital's transfusion disposable transfusion device, the control of transfusion speed, adopt the position of roller bearing in surface groove, the size that tube for transfusion is exerted pressure is regulated its shortcoming: 1, can't accurately show and regulate transfusion speed; 2, operator need retest when regulating number of infusion drops, expend time in troublesome poeration; 3, the easy upward displacement in the position of roller bearing in chute causes transfusion speed to accelerate, and to strong antihypertensive drugs, easily causes danger.At present, be head it off, existing more patent occurs, and these patents respectively have characteristics, to regulating transfusion speed certain effect is arranged, but the complex structure that has, and the needs that have expend electric power, involve great expense, and what have is unfavorable for aseptic principle again.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can intuitively show flow velocity, easy to use, safe by pointer, the transfusion device that transfusion speed can trace regulation and control.

The purpose of this utility model adopts following technical measures to realize: the controlled micrometeor transfusion device of a kind of pointer-type, form by box body, spool, knob, it is characterized in that: a hole that connects is arranged in the box body bottom, its aperture ratio tube for transfusion diameter is slightly thick, one valve core chamber is arranged above the hole, the indoor spool that is equipped with, spool is a cylinder, the lower end is the bullet of round end, there is a screw mandrel spool upper end, and the knob of female thread is housed on the screw mandrel, and knob is installed in the space on box body top, be fixed with pointer on the screw mandrel, be shaped on scale on the box body surface.

Remarkable result of the present utility model: can intuitively show flow velocity, easy to use, safe by pointer, transfusion speed can be regulated and control by trace, production technology and simple in structure, and cost is low, is beneficial to keep aseptic principle.
