DETAILED DESCRIPTION

[0034] Combined with Figure 1-Figure 10 The device for quantitatively feeding medicine to infants and young children comprises a syringe 11, a cavity is provided in the syringe 11 and a piston 34 is slidably installed, a piston shaft 18 is fixed at one end of the piston 34, a piston handle 17 is fixed at the end of the piston shaft 18, and an injection head 39 is fixedly connected to the front end of the syringe 11. The piston shaft 18 and the piston 34 are driven to move by pulling the piston handle 17. The movement of the piston 34 can realize negative pressure in the cavity of the syringe 11, and the liquid medicine is drawn into the cavity of the syringe 11:

[0035] A dosing assembly 50 is provided on the injection barrel 11;

[0036] During use, the syringe 11 is not stable enough and can easily collide with the inside of the infant's mouth and cause damage. To this end, the applicant fixedly installed an airbag 12 on the syringe 11, and the airbag 12 is fixedly connected to one end of the trachea 13, and the trachea 13 is fixedly connected to the latex inflatable ball 15. The latex inflatable ball 15 is fixedly installed with a copper air valve 14 and a return air valve 16. After the syringe 11 is inserted into the infant's mouth, the latex inflatable ball 15 is manually squeezed to allow the airbag 12 to expand and hold the infant. The tongue and upper palate of the infant are prevented from colliding with the syringe barrel 11 and the inner side of the infant's mouth, thereby improving the safety and stability of medicine feeding. When feeding medicine, the air bag 12 can block part of the infant's mouth to prevent the medicine liquid from being spit out, and can also make the medicine liquid directly enter the esophagus without passing through the mouth, thereby preventing the mouth from affecting the medicine liquid and improving the effect of the medicine liquid. Manually releasing the copper air valve 14 can realize the deflation of the air bag 12, so that the air bag 12 is deflated (please refer to the common components of manual blood pressure measurement for this part of the structure);

[0037] Infants and young children need to be fed with a certain amount of medicine multiple times so that the medicine can be stably effective without over-stimulating the infants and young children. To this end, the applicant has opened a plurality of pairs of grooves on the syringe 11 inside the airbag 12, each pair of grooves including at least one intermediate groove 33, and a barrier film 32 is fixed in each intermediate groove 33 to isolate the airbag 12 from the inner cavity of the syringe 11. The barrier film 32 is elastic. After the airbag 12 is inflated, the barrier film 32 will collide with the inner cavity of the syringe 11 under pressure to form a bulge. When the piston 34 moves along the inner cavity of the syringe 11 to feed the medicine, it will be blocked by the raised intermediate groove 33. The user will feel resistance when continuing to push the piston 34, which means that a certain amount of liquid medicine has been fed. The user will continue to push the piston 34 when feeding a certain amount of liquid medicine next time until the piston 34 is blocked by the next raised intermediate groove 33 and feels resistance again.

[0038] It is particularly important to note that the syringe 11 is marked with an identification to ensure that the amount of liquid medicine extracted is a constant value, so that the quantitative distribution of the liquid medicine can be achieved in cooperation with the barrier membrane 32. After the injection of the liquid medicine is completed, the copper air valve 14 is manually controlled to achieve exhaust, and the barrier membrane 32 can also be reset.

[0039] The dosing assembly 50 includes a dosing box 20 fixed on the injection barrel 11, at least one dosing groove 23 is provided on the top of the dosing box 20, a connecting groove 35 connecting the dosing groove 23 and the inner cavity of the injection barrel 11 is provided in the dosing box 20, a dosing block 36 is rotatably installed in the connecting groove 35, the dosing block 36 and the connecting groove 35 are kept sealed, a rotating shaft 30 penetrating to the outside is fixed on one side of the dosing block 36, a knob 28 is fixed on one end of the rotating shaft 30, a receiving groove 37 is provided on the top of the dosing block 36, a medicine pushing block 38 is slidably installed in the receiving groove 37, and the medicine pushing block 38 and the receiving groove 37 are rotatably installed. The medicine is fixed by at least one spring 41, and the medicine is added from the medicine adding groove 23 and falls into the receiving groove 37 at the top of the medicine pushing block 38. The medicine adding block 36 is driven to rotate 180 degrees by manually turning the knob 28, and the receiving groove 37 will be connected to the inner cavity of the injection barrel 11. At this time, the medicine pushing block 38 will move along the receiving groove 37 under the action of gravity, and the medicine in the receiving groove 37 will be completely pushed out into the inner cavity of the injection barrel 11, and the spring 41 will be stretched. After completion, the knob 28 is manually turned to reset the medicine adding block 36, and the spring 41 will also reset, driving the medicine pushing block 38 to reset.

[0040] It is particularly important to note that two identification blocks 27 are fixed on the medicine adding box 20, and a pointer 29 is fixed on the knob 28. The two identification blocks 27 represent "waiting for medicine adding state" and "dosing state" respectively, and cooperate with the pointer 29 to realize the position control of the knob 28.

[0041] However, many drugs are difficult for infants to swallow. For this reason, a drug crushing assembly is installed on the top of the drug adding box 20. The drug crushing assembly includes a support seat 22 fixed on the top of the drug adding box 20. The support seat 22 is provided with guide grooves 26 of the same number as the drug adding grooves 23. A guide rod 24 is slidably provided through the guide grooves 26. One end of the guide rod 24 is fixed to a pressure sheet 25. The other end of the guide rod 24 is fixed with a crushing head 42 that slidably cooperates with the drug adding groove 23. At least one drug inlet hole 43 connected to the connecting groove 35 is provided at the bottom of the drug adding groove 23. The pressure sheet 25 is manually lifted to pull the crushing head 42 out of the drug adding groove 23. At this time, the drug can be manually added to the drug adding groove 23. The crushing head 42 crushes the drug by manually pushing the pressure sheet 25. The crushed drug will fall from each of the drug inlet holes 43 to the top of the drug pushing block 38.

[0042] Furthermore, a pin 44 is fixed at the bottom center of the drug adding groove 23. The pin 44 is conical and supports the drug. Together with the crushing head 42, the drug can be crushed more conveniently and evenly. The drug entering the inner cavity of the injection barrel 11 will dissolve in the drug solution or water sucked into the inner cavity of the injection barrel 11.

[0043] In addition, in order to prevent the liquid medicine injected into the infant's mouth from being too irritating to the infant, at least one spray hole 40 is opened around the injection head 39, and the liquid medicine will be discharged from each spray hole 40, thereby evenly spreading into the infant's esophagus.

[0044] The injection head 39 is provided with a thread and is threadedly connected with a sealing nozzle 21 , through which the injection hole 40 can be closed. At this time, the injection head 39 can be manually shaken to allow the drug to fully dissolve in the drug solution in the injection barrel 11 .

[0045] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
