Problems solved by technology
However, due to the elasticity of the infusion tube and the smooth outer wall, the rollers tend to roll back after adjustment, affecting the accuracy of speed regulation; in addition, the patient's body movements are also likely to affect the adjustment accuracy of the regulator, which will adversely affect the treatment. Accidents may also occur, endangering the personal safety of patients
[0004] Some modifications and innovations have been made to the infusion regulator in the prior art, but there are still problems such as complex structure and insufficient reliability, which are not conducive to popularization and utilization

Embodiment Construction
[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] see Figure 1~4 , a knob-type infusion speed regulator, comprising a main body 1, a speed-regulating knob 2 and a speed-regulating lever 6. The main body 1 is made of plastic, and is provided with an infusion tube through hole 7 that runs through the main body left and right. The cross-sectional diameter of the infusion tube through hole 7 matches the diameter of the infusion tube 3, and the infusion tube 3 can just pass through the infusion tube through hole 7. See Figure 4 . The upper part of the main body 1 is provided with a speed regulating rod through hole with an internal thread connecting the upper surface of the main body and the through hole of the infusion tube. The speed regulating rod 6 is a screw rod, and its external thread matches the internal thread of the speed regulating rod through hole. The rod 6 can be inserted...

The invention discloses a knob-type infusion speed regulator, and belongs to the field of medical apparatus and instruments. The knob-type infusion speed regulator comprises a main body and a speed regulating rod. The main body is provided with an infusion pipe through hole, and the speed regulating rod can move up and down. The speed regulating rod penetrates into the infusion pipe through hole from the upper portion of the main body. The knob-type infusion speed regulator is an auxiliary product for a disposable infusion apparatus. During production of the disposable infusion apparatus, an infusion pipe is penetrated through the infusion pipe through hole, and accordingly the knob-type infusion speed regulator is sleeved on the infusion pipe. When the knob-type infusion speed regulator is used, a medical worker rotates a speed regulating knob to a required dripping speed scale and the infusion pipe is oppressed by the lower portion of the speed regulating rod to be deformed, so that the purpose of controlling the dripping speed of drug fluid accurately can be achieved, and the dripping speed of the drug fluid can be kept stably. The knob-type infusion speed regulator is safe and convenient, simple in structure, low in cost and convenient to popularize and apply.
Description
[0001] technical field [0002] The invention belongs to the field of medical equipment, in particular to a knob type infusion speed regulator. Background technique [0003] It is known that the drop rate of the medicinal liquid in the disposable infusion set widely used at present is controlled by the regulator installed on the infusion tube, that is, the roller on the sliding regulator is used to squeeze the infusion tube to deform, thereby controlling the passage of the medicinal liquid. speed. However, due to the elasticity of the infusion tube and the smooth outer wall, the rollers tend to roll back after adjustment, affecting the accuracy of speed regulation; in addition, the patient's body movements are also likely to affect the adjustment accuracy of the regulator, which will adversely affect the treatment. Accidents can also occur, endangering the personal safety of patients. [0004] Some transformations and innovations have also been carried out for the infusion...
