Embodiment Construction
[0012] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
[0013] Such as figure 1 , figure 2 , image 3 As shown, the fine-tuning device for the flow of an infusion set according to the present invention includes an adjustment wheel 1, a wheel box 2, and a central shaft 3; one side of the adjustment wheel 1 is provided with an arc-shaped flow adjustment groove with a depth ranging from deep to shallow 4. The other side of the adjustment wheel 1 is provided with a circular flow channel groove 5 with the same depth. The center of the flow channel groove 5 and the flow adjustment groove 4 is on the axis of the central axis 3. The deepest position of the flow adjustment groove 4 is provided with Connect the through hole 6 of the runner groove 5; the wheel box 2 is arranged on both sides of the adjustment wheel 1, and the adjustment wheel 1 is connected and positioned with the wheel box 2 through the central a...

The invention provides an infusion device flow fine-adjustment device. The infusion device flow fine-adjustment device comprises an adjusting wheel, wheel boxes and a middle shaft. One side face of the adjusting wheel is provided with a flow adjusting trough, wherein the flow adjusting trough is of an arc shape and the depth of the flow adjusting trough is gradually reduced. The other side face of the adjusting wheel is provided with a flow channel trough, wherein the flow channel trough is circular and the depth of the flow channel trough is constant. The circle center of the flow channel trough and the circle center of the flow adjusting trough are located on the axis of a middle shaft. A through hole connected with the flow channel trough is formed in the deepest position of the flow adjusting trough. The wheel boxes are arranged on the two sides of the adjusting wheel. The adjusting wheel is connected with the wheel boxes for positioning through the middle shaft. The wheel boxes on the two sides are respectively provided with a guide pipe. The ends of the two guide pipes are communicated with the flow adjusting trough and the flow channel trough respectively. The infusion device flow fine-adjustment device has the advantages of being simple in structure, low in manufacturing cost and safe and reliable in use and enabling flow to be adjusted by one hand.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a flow fine-tuning device for an infusion set. Background technique [0002] Intravenous infusion is a very common clinical treatment method. In the clinical process, especially for infants, young children, the elderly and patients with poor heart function, it is very important to control the infusion rate. Improper infusion rate may have serious consequences. However, at present, many infusion device speed adjustment devices have complex structures, high cost, need two-handed operation, rotation of the infusion tube during operation may cause pain to the patient, etc., and the overall performance needs to be improved. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a flow fine-tuning device for an infusion set, which has a simple structure, low cost, can adjust the flow with one hand, and is safe and reliable to use...
