Problems solved by technology

[0002] At present, clinically, when patients take medicinal liquid, they mostly observe the medicine bottle, visually divide the medicinal liquid into equal parts according to the single scale mark on the medicine bottle, and roughly estimate the dosage, or It is to pour the medicinal liquid into the cup before taking the medicine, so that the dosage cannot be accurately determined when taking the medicine, and the operation is troublesome, which increases the patient's taking medicine difficulty
There are also ​using a needle tube to draw out a specified amount of liquid medicine from the liquid medicine bottle and put it into a cup before taking it. If the needle penetrates into the liquid medicine bottle, it will contaminate the liquid medicine in the bottle and suck it into the measuring cup. When there is too much medicine in the bottle, it is necessary to put the excess medicine into the medicine bottle, which will also cause pollution of the medicine in the bottle

Abstract

The invention provides a drug delivery device. The device includes a body, a drug feeding hole and a dosage adjustment device. The drug delivery device is characterized in that the dosage adjustment device is composed of an adjustment knob, an regulating disc and a regulating screw. The adjustment knob is provided with a dosage display window and a marking rod. When the adjustment knob is rotated,the regulating disc rises along the screw, the volume of a body changes accordingly, and the dosage display window displays the volume of the body after adjustment. In addition, there is a stereo scale mark on the body. When the adjustment knob rotates to a specific dose unit, the stereo scale mark causes the edge of the window to be stuck in a designated position so as to avoid the change of thevolume of the body due to the action of placement and the like.
