Abstract
The utility model relates to a transfusion set with easy speed regulation, and comprises a transfusion tube (1) and speed regulation switches arranged on the transfusion tube (1). The number of the speed regulation switches is two which are a crude regulation switch and a fine regulation switch. The slope angle of the skewed slot (4) of the crude regulation switch is larger than that of skewed slot (4') of the fine regulation switch. The transfusion set can conveniently and accurately regulate the speed of transfusion; s the crude regulation switch is regulated when the transfusion speed needs to be changed rapidly, and the fine regulation switch is regulated when the transfusion speed needs to be changed accurately; the transfusion set is especially suitable for the transfusion occasions having strict requirement for the transfusion speed.
Description
Technical field
This utility model relates to a kind of medical Transfusion device, the particularly a kind of easy speed governing transfusion device that can accurately regulate transfusion speed.
Background technology
The speed-regulating switch of existing transfusion device comprises framework and regulating wheel, and skewed slot is offered in the framework both sides, and regulating wheel places in the skewed slot by axle, during use, tube for transfusion passes framework, rotates regulating wheel and moves may command to the depression degree of tube for transfusion along skewed slot, thereby regulate transfusion speed.The problem that exists is: existing transfusion device speed-regulating switch has only one, when needs are finely tuned transfusion speed, need carefully rotate regulating wheel, and it is very inconvenient to regulate control, also is difficult to reach the requirement of fine adjustment speed.
Summary of the invention
The purpose of this utility model is to provide a kind of easy speed governing transfusion device that overcomes above-mentioned shortcoming, can convenient, accurately adjust transfusion speed.
This utility model is achieved in that a kind of easy speed governing transfusion device, comprise tube for transfusion and the speed-regulating switch that is arranged on the tube for transfusion, speed-regulating switch comprises guide frame and places the interior regulating wheel of guide frame, the guide frame both sides are provided with skewed slot, this speed-regulating switch is two, be respectively coarse adjustment switch and fine tuning switch, the skewed slot angle of inclination of coarse adjustment switch is greater than the skewed slot angle of inclination of fine tuning switch.
The utility model has the advantages that: by two speed-regulating switch are set, can make things convenient for, regulate accurately transfusion speed, when needing to change transfusion speed fast, adjust the coarse adjustment switch, when needing accurately to change transfusion speed, regulate the fine tuning switch.
Description of drawings
Fig. 1 looks sketch map for master of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in the figure, this utility model is provided with two speed-regulating switch on tube for transfusion 1, be respectively coarse adjustment switch and fine tuning switch, both structures are formed identical, respectively by guide frame 2, regulating wheel 3 and guide frame 2 ', regulating wheel 3 ' constitute, guide frame 2,2 ' on offer respectively skewed slot 4,4 ', the difference of coarse adjustment switch and fine tuning switch be skewed slot 4 and skewed slot 4 ' the angle of inclination different.The angle of inclination of the skewed slot 4 of coarse adjustment switch is big, regulating wheel 3 is fast along the rising or falling speed of skewed slot 4, is applicable to quick variation transfusion speed, the skewed slot 4 of fine tuning switch ' the angle of inclination little, regulating wheel 3 ' along skewed slot 4 ' rising or falling speed slow, be applicable to accurate adjustment transfusion speed.This utility model is specially adapted to transfusion speed is had the transfusion place of strict demand.
Claims (1)
1, a kind of easy speed governing transfusion device, comprise tube for transfusion and the speed-regulating switch that is arranged on the tube for transfusion, speed-regulating switch comprises guide frame and places the interior regulating wheel of guide frame, the guide frame both sides are provided with skewed slot, it is characterized in that: this speed-regulating switch is two, be respectively coarse adjustment switch and fine tuning switch, the skewed slot of coarse adjustment switch (4) angle of inclination is greater than skewed slot (4 ') angle of inclination of fine tuning switch.
