Abstract
The utility model relates to a fine speed adjusting switch of a transfusion device for a patient's transfusion, which comprises a long rectangular box-shaped supporting frame 2 without a top cover, wherein two long end faces of the supporting frame 2 are provided with holes and a transfusion rubber pipe 3 can thread through the holes. Two side panels are provided with four inclined rectilinear shape or cambered shape adjusting slot holes 4 in a bisymmetrical way, and moreover, the inclined angle of each adjusting slot hole is identical or different. The front parts and the rear parts of two adjusting wheels 1 are installed above the transfusion pipe 3 in the box-shaped supporting frame 2. Wheel shafts can respectively and horizontally thread through the bisymmetrical adjusting slot holes 4, and the wheel edges are pressed on the transfusion rubber pipe 3. The fine speed adjusting switch of the transfusion device has two adjusting wheels for the coarse adjustment and the fine adjustment, so that after one adjusting wheel can approximately adjust the speed of the transfusion, the other adjusting wheel is rotated to carry out the fine adjustment. Thus, the utility model can squeeze the transfusion rubber pipe in different degrees so as to obtain the satisfactory speed of the transfusion.
Description
Technical field
This utility model relates to a kind of the transfusion to the patient and uses the meticulous speed-regulating switch of transfusion device.
Background technology
When infusing to the patient, speed to transfusion is that certain area requirement is arranged, the method of existing adjusting transfusion speed is to adopt speed-regulating switch, its composition comprises a half-headed long square box-section trestle, perforate on the panel of two ends can be passed the transfusion sebific duct, and symmetry has the linear adjusting slotted eye of inclination on the panel of both sides, regulating wheel is contained in central, the transfusion sebific duct top of box-section trestle, and its wheel shaft crosses aforesaid adjusting slotted eye.Make wheel shaft downward along the adjusting slotted eye that tilts if dial to change regulating wheel, then the regulating wheel sebific duct extruding of will infuse is flat, and transfusion speed descends, on the contrary then rising.Because the difference of fluid infusion, patient's body constitution, sometimes the adjusting to transfusion speed requires very accurate, but existing speed-regulating switch is owing to the angle of inclination of regulating slotted eye is fixed and has only a pair of, so be difficult to accurately regulate transfusion speed, need to adjust back joint step by step and just can meet the demands, for clinical position brings many troubles.
The utility model content
The purpose of this utility model just provides a kind of accurately meticulous speed-regulating switch of transfusion device easy to use of regulating.
For realizing above-mentioned utility model purpose, the meticulous speed-regulating switch of transfusion device of the present utility model, comprise a half-headed long square box-section trestle, perforate on the panel of two ends, the transfusion sebific duct can be passed, symmetry has the adjusting slotted eye of inclination on the panel of both sides, and regulating wheel is contained in the central transfusion sebific duct top of box-section trestle, and its wheel shaft crosses aforesaid adjusting slotted eye.It is characterized in that: the described adjusting slotted eye that symmetry has an inclination on the panel of both sides has two pairs at least, and the regulating wheel that matches is with it arranged.
On the basis of the above, this utility model also can be done further perfect:
Described two pairs of symmetric adjusting slotted eye gradient differences.
Described adjusting slotted eye is an arc-shaped slot.
The beneficial effects of the utility model are: because the meticulous speed-regulating switch of this transfusion device has two regulating wheels, one is coarse adjustment, one is fine setting, after using a regulating wheel roughly to regulate transfusion speed, rotate another regulating wheel again and carry out trace adjustment, can push the transfusion sebific duct to some extent, thereby obtain satisfied transfusion speed.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
From Fig. 1 to Fig. 3, can see, the embodiment 1 of the meticulous speed-regulating switch of transfusion device of the present utility model, comprise a half-headed long square box-section trestle 2, on its two long end plates, have the hole, transfusion sebific duct 3 can be passed, the linear that the two sides has four inclinations symmetrically altogether on the panel of both sides is regulated the top that 4, two regulating wheel 1 front and back of slotted eye are contained in transfusion sebific ducts 3 in the middle of the box-section trestle 2, and its wheel shaft passes across the symmetric adjusting slotted eye 4 in two sides, wheel respectively along being pressed on the transfusion sebific duct 3.When rotating arbitrary regulating wheel, wheel shaft is downward along the adjusting slotted eye that tilts, and then the regulating wheel sebific duct extruding of will infuse is flat, and transfusion speed descends, on the contrary then rising.Carry out trace adjustment owing to there are two regulating wheels can push the transfusion sebific duct to some extent, thereby obtain satisfied transfusion speed.
4, two pairs of symmetric adjusting slotted eyes of embodiment shown in Figure 7 are arc-shaped slot gradient difference, and the principle of regulating transfusion speed is the same.
Claims (3)
1, the meticulous speed-regulating switch of a kind of transfusion device, comprise a half-headed long square box-section trestle (2), on its two long end face, have the hole, transfusion sebific duct (3) can be passed, have the adjusting slotted eye (4) of inclination on the panel of both sides symmetrically, regulating wheel (1) is contained in the middle of the box-section trestle (2), the top of transfusion sebific duct, and its wheel shaft passes across two and regulates slotted eyes, wheel along being pressed on the transfusion sebific duct, it is characterized in that: described adjusting slotted eye has two pairs four at least, and the regulating wheel that matches is with it arranged.
