The synchronizing wheel is provided with a screw hole, and the screw rod is fixed on the synchronizing wheel through a fixing screw, so that the synchronizing wheel can drive the screw rod to rotate synchronously.
The side surface of the pressing plate is provided with an inward concave groove, the nut is pressed into the groove from the side, and pressing plate holes for the screw rods to pass through are formed in the two sides of the groove.
Set up bottom plate limit switch 8 on the casing bottom plate, still be equipped with clamp plate limit switch 9 in the casing, move to press bottom plate limit switch when the clamp plate to the direction of casing bottom plate and make it switch on, the control panel stops to give motor input forward power and sends the sound suggestion that the infusion was accomplished or give the light suggestion that the infusion was accomplished through display panel.
When a reset key on the shell is pressed, the control panel inputs a reverse power supply to the motor to reset the pressing plate, and the infusion bag in the shell is taken out after the pressing plate is reset.
The infusion bag is placed into the shell from the limiting hole, the limiting plate covers the limiting hole to be fixed, and the infusion nozzle is exposed out of the limiting groove.
The magnetic blocks 13 are arranged on the shell body on the two sides of the limiting hole, the limiting plate is made of a metal plate, the limiting plate is sucked by the magnetic blocks on the two sides of the limiting hole, and when the limiting plate is to be taken down, the limiting plate can be taken down by overcoming the suction force of the magnetic blocks as long as being pulled forcefully.
As shown in fig. 7, two opposite sides of the housing are respectively provided with a positioning plate 14, and the infusion bag is positioned between the two positioning plates to prevent the infusion bag from sliding sideways.
Be equipped with backup pad 15 in keeping away from the casing in spacing hole, clamp plate limit switch fixes in the backup pad, and the clamp plate is supported when reseing and is accomplished reseing to clamp plate limit switch promptly.
The screw rod has three options. One is a common threaded screw rod matched with a common hexagon nut, and the accuracy of the method is low.
The second type is a trapezoidal screw rod which is matched with a screw rod nut, threads in the screw rod nut are matched with the trapezoidal screw rod, and the cost is low.
The third is a ball screw, which also cooperates with a screw nut, inside which are beads, which cooperate with grooves on the ball screw, which is a lower cost but with a higher precision.

The specification of a dropper which is commonly used in clinic shows that there are two types of droppers, 9cm and 10cm, and 20 drops together are 1ml, so that the average drop is 0.05 ml. Another clinical device for containing liquids is an infusion set used for intravenous infusion, where one drop is equal to 0.04ml on average, or 0.05ml and about 0.06 ml. Because infusion sets have different specifications, different infusion set algorithms are different. Like a conventional disposable infusion set and a dropper, the volume of the infusion set is 1ml after 20 drops are added; the water drop of the precision infusion apparatus is larger, and the water drop of the precision infusion apparatus is 1ml, namely 15 drops; the children transfusion device special for children has the minimum water drop because the dropping speed required by children is relatively slow, and the water drop can reach 1ml only after 60 drops. The infusion apparatus is different, the volume of one drop of the infusion apparatus is different, and the medicine added in the infusion apparatus is different after the medicine is added.
Principle of drop speed regulation: generally, about 40-60 drops/min for adults and 20-40 drops/min for children. But also needs to be adjusted according to the age, the disease condition and the drug property of the patient, and the speed is suitable for patients with heart, lung and kidney diseases, old patients, children and patients who input hypertonic saline, potassium-containing or pressure-increasing drugs; the speed can be properly accelerated for severe dehydration and good cardiopulmonary function.
Taking an infusion bag of 120mm by 180mm 21600mm2 as an example, if the infusion requires 2ml to 3ml per minute, the compression plate is required to be lowered by 0.1mm per minute. The controller controls the rotation speed of the motor by controlling the electric quantity output to the motor.
In addition, in practical application, in order to simultaneously infuse a plurality of people and individually control the infusion speed of each person, a plurality of groups of suspension-free infusion machines are combined together and arranged by using one shell, so that the infusion can be simultaneously performed on the plurality of people.
After the infusion is finished, the reset speed of the pressure plate is usually required to be a little faster, so that the controller can input larger reverse current to the motor to realize quick reset.
The above embodiments are only used for illustrating and explaining the utility model, and are not intended to limit the present invention, and those skilled in the art can make various changes or substitutions within the scope of the present invention, and shall also belong to the protection scope of the present invention.
