The exemplary embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention. Further description below in conjunction with accompanying drawings.

As shown in Figures 1-6, the present invention provides an adjustable precision continuous syringe, including a liquid suction pull plate 1, a switch 6, a liquid suction button 16, an injection press plate, a first syringe 4, and a second syringe 3 , ladder piston arm 13, needle seat 5, injection arm 2, positioner, positioning needle 14, first spring 18, second spring 23, first motor 24, second motor 20, first gear 21, second gear 26. Connecting wire 25, intelligent control chip, touch screen, setting plus key 10, setting minus key 11, indicator light 8, digital display 12, screen touch lock 9, button battery 17, battery compartment cover 7.

The syringe is controlled by a smart chip. The syringe is double-layered, including a first syringe 4 and a second syringe 3, the first syringe 4 holds the injection piston 15 and stores the medicinal solution. The second syringe 3 contains the injection arm 2, the button battery 17, the first motor 24 and the second motor 20, etc. There is a touch screen on the outside of the second syringe 3, and the injection arm is provided with a quantitative thread 19, which can realize precise injection .

The liquid suction pull plate 1 is connected to the liquid suction arm, which is a ladder-shaped piston wall 13 , and the liquid suction arm has an inverted triangle with precise quantification to ensure precise injection driven by the positioning needle 14 . The suction arm is used for aspirating liquid medicine and precise dosing, both arms can do precise dosing.

The ladder-shaped piston wall 13 restricts the movement of the positioning pin 14, and the time is also controlled by the positioning pin 14. When the injection pressing plate is pressed, the injection pressing plate drives the positioning pin 14 to move, and the positioning pin 14 drives the ladder-shaped piston wall 13 to move at the same time. The piston wall 13 drives the piston to discharge the liquid medicine from the syringe. Since the ladder-shaped piston wall 13 is designed as an inverted triangle, the positioning pin 14 on the positioner automatically returns to its original position under the action of the first spring 18 and the second spring 23 after the injection is completed, and the positioning pin 14 A part is cylindrical, and a part is a rack 22 , which matches with the first gear 21 .

On the injection arm 2, there is a touch screen, and the bottom of the touch screen is an intelligent control chip. The touch screen has a setting plus key 10 and a setting minus key 11 to set the injection dose. The digital display area can display two digits with a decimal point in the middle, that is, it can be accurately injected to one digit after the decimal point. According to injection needs, syringes with different ranges can be designed and produced, such as two digits after the decimal point. After the screen touch lock 9 locks the screen, the first motor 24 moves the positioning pin 14 to the setting dose place, clicks the screen touch lock 9 screen three times to allow touch and adjustment, and clicks the screen touch lock 9 lock screen once after setting.

Below the touch screen are the suction button 16 and the switch 6 key. Click the liquid suction button 16 to switch 6, and the positioning needle 14 is retracted under the drive of the first motor 24. At this time, the liquid medicine can be sucked. Press the liquid suction button 16 again after air bubbles, and the positioning pin 14 returns to its original position.

The injection arm 2 is designed in a spiral shape, which can accurately quantify the injection dose. The first motor 24 can move up and down on the injection arm 2 and automatically move to the position where the dose is set. After the injection is completed, the positioning needle 14 returns automatically under the action of the first spring 18 and the second spring 23 . The button battery 17 provides electric energy for the first motor 24 and the second motor 20, and the battery compartment cover 7 is tightly sealed and waterproof.

The syringe is designed as two layers, the piston arm is designed as a trapezoidal inverted triangle, and the scale line is placed on the injection arm 2 and the suction arm. Dosage required. The dose adjustment is automatically positioned by the locator to precisely lock the injection dose. The injection arm 2 can return to its original position automatically and can inject continuously. It effectively avoids problems such as inaccurate dosage, unclear scale, injection angle, liquid leakage, and air bubbles. Achieve continuous, precise and rapid injection, greatly improving the efficiency of experiments.

In this embodiment, the first syringe 4 can be thickened and lengthened to expand the capacity, increase the injection capacity, and reduce the number of times of extracting the liquid medicine. The unit of the spiral design on the injection arm 2 is smaller to improve the precision of injection.

The beneficial effect of the patent of the present invention is: the syringe is equipped with a button battery 17 and an intelligent control chip, and the injection dose can be set through the touch screen, which is electronically adjusted, and the setting is fast and accurate, and can be used for multiple times after one setting, and there is no need for naked eye quantification during injection , to avoid injection errors. One extraction of medicinal liquid can complete multiple precise injections until the medicinal liquid in the first syringe 4 is injected, and the injection dose can be adjusted at any time. The injection speed is extremely fast, reducing repetitive labor in the epidemic prevention injection operation and greatly improving work efficiency. At the same time, the patented invention has the advantages of simple structure, convenient use, reasonable structural design, and only one person can inject livestock, and the manufacturing cost is not high. It is suitable for all injections and is worthy of popularization and use.

The existing continuous syringe is generally equipped with a medicine tank, and the medicine liquid is placed through the medicine tank, and the angle of injection must be guaranteed, which is inconvenient to operate. This embodiment is an adjustable precision continuous injector, which overcomes the shortcomings of the above-mentioned prior art, and provides a continuous injector with simple structure, low cost, convenient operation and use, safety and reliability. At the same time, a syringe for gavage is provided, and the scale wear phenomenon of the syringe and the coincidence problem between the color of the liquid and the scale do not occur during the use of the syringe. At the same time, it effectively ensures that the experimenter can accurately grasp the dosage of the drug, and can quickly and accurately adjust the injection dosage anytime and anywhere. It is easy to use and widely used.
