Abstract
Description
Technical Field
[0001] The utility model relates to the field of infusion sets, in particular to a fine-tuning infusion set. Background Art
[0002] Intravenous infusion is a common clinical treatment method. In the clinical process, it is particularly important to control the infusion speed for infants, children, the elderly and patients with poor heart function. A faster infusion speed will cause discomfort to the patient's body, and a slower infusion speed will prolong the patient's infusion time. The current commonly used method is a sliding sleeve and a pulley to solve the problem. The pulley slides in the sliding sleeve and squeezes the outer wall of the infusion tube so that the infusion tube is compressed, thereby reducing the infusion caliber of the corresponding part of the infusion tube to achieve the purpose of controlling the infusion speed. However, in actual use, the above method is generally roughly adjusted by the patient or the accompanying person when adjusting, and it is difficult to achieve more subtle adjustments. For example, when encountering a more stimulating drug solution, it is generally necessary to adjust the infusion speed more slowly. If it is roughly adjusted, it may cause the infusion time to be excessively extended. In addition, since the infusion tube is mostly made of PVC or PE material, the elasticity is poor, and the restoring force is poor after being squeezed by the pulley, it will remain in the squeezed state or slowly return to the original state, which also affects the patient or the accompanying person to adjust the infusion speed of the infusion device.
