Abstract

The utility model discloses a transfusion device adjusting clamp capable of adjusting flow slightly. The utility model is characterized in that an upper part and a lower part of a front part of a clamp body (1) are respectively provided with a horizontal semi-circular hole (2); a valve core chamber (4) is disposed on an upper part of the hole, and a valve core (5) is disposed in the chamber; the valve core is a cylinder body, and a lower end is a conical body (6) provided with a round head; a lead screw (7) is disposed on an upper end of the valve core, and a top end of the lead screw is provided with an adjusting knob (8). The transfusion device adjusting clamp provided in the utility model can be used to overcome the defects of the conventional transfusion devices that the flow can not be adjusted slightly, and the transfusion devices cannot be visually observed. By using the transfusion device adjusting clamp provided in the utility model, the flow velocity can be visually observed by arranging a pointer, the use is convenient and safe, the transfusion speed can be adjusted slightly, the production technology as well as structure is simple, and the costs are low.

Description

The transfusion device adjustable clamp of fine-tuning flow

Technical field

This utility model relates to the medical infusion field, but the Infusion clip of a kind of more precisely micrometeor regulation and control.

Background technology

Transfusion is one of conventional medical procedure, and is in treatment clinical course, important for the control of transfusion speed; The input speed of a lot of patients' all strict control intravenous fluids of the state of an illness particularly more should be noted the speed of venous transfusion for the relatively poor patient of baby, children, child, old people and cardiac function, do not note slightly just acute heart failure possibly occurring; Even cause death, and at present, hospital's transfusion disposable transfusion devices that adopt more; The position of roller bearing in surface groove adopted in the control of transfusion speed, and 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, is prone to cause 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 through pointer, the transfusion device that transfusion speed can trace regulation and control.

The purpose of this utility model adopts following technical measures to realize: a kind of transfusion device adjustable clamp of fine-tuning flow, form by clamp, spool, adjusting knob, and it is characterized in that: the hole that a horizontal semicircle is respectively arranged up and down in the clamp front portion; Its aperture ratio tube for transfusion diameter is slightly thick, a valve core chamber is arranged, the indoor spool that is equipped with above the hole; Spool is a cylinder; The lower end is the bullet of round end, and there is a screw mandrel spool upper end, and adjusting knob is housed on the screw mandrel; Pointer fixedly is housed on the screw mandrel, is shaped on scale on the clamp face.

The remarkable result of this utility model: can intuitively show flow velocity, easy to use, safe through 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.
