Claims

1. A pediatric nursing medication delivery device, characterized in that: The device includes an injection tube, a feeding head, a pusher, and a limiting assembly. The pusher includes a push rod, a piston, and a pressing plate. The piston is located at the front end of the push rod, and the pressing plate is located at the rear end of the push rod. The front end of the push rod and the piston are located inside the injection tube. The piston is in contact with the inner wall of the injection tube. The front end of the injection tube has an open opening. The feeding head is located at the front end of the injection tube, and the rear end of the feeding head is connected to the front end of the injection tube. The front end of the feeding head has a feeding port. By filling the injection tube with liquid medicine and pressing the pressing plate to drive the piston to move inside the injection tube, the piston squeezes the liquid medicine inside the injection tube to move towards the feeding port through the channel provided inside the feeding head and squeezes it out from the feeding port. The injection tube has a limiting component at its tail end, which includes a limiting sleeve, a base plate, and a limiting ring plate. The injection tube has a limiting cavity at its tail end, with the limiting sleeve located inside the cavity. The push rod passes through the limiting sleeve and moves up and down within it. A threaded hole is located near the outer end of the limiting cavity, and the outer wall of the limiting sleeve has a threaded structure. The limiting sleeve and the threaded hole are spirally connected. The base plate is located at one end of the limiting sleeve and inside the limiting cavity. The limiting ring plate is located at the other end of the limiting sleeve and outside the limiting cavity. By rotating the limiting sleeve, the distance between the outer limiting ring plate and the outer wall of the limiting cavity can be adjusted. When the pressing plate is pushed, it is limited by the limiting ring plate, thereby controlling the amount of liquid medicine squeezed out of the injection tube by the piston.

2. The pediatric nursing medication feeding device according to claim 1, characterized in that: The channel is Y-shaped, and there are two feeding ports, which are located on both sides of the front end of the feeding head.

3. The pediatric nursing medication feeding device according to claim 1, characterized in that: The front end of the feeding head is provided with a protective cover, which is engaged with the outer wall of the feeding head.

4. A pediatric nursing medication feeding device according to claim 3, characterized in that: The inner wall of the protective cover is provided with a retaining ring, and the outer wall of the feeding head is provided with a retaining groove. The protective cover and the feeding head are engaged with each other by the retaining groove and the retaining ring.

5. A pediatric nursing medication feeding device according to claim 1, characterized in that: The push rod has a scale mark on the side near the pressing plate. The scale mark includes several equal parts. The limiting ring plate cooperates with the scale mark to achieve precise adjustment of the medication dosage.

6. A pediatric nursing medication feeding device according to claim 1, characterized in that: The lower end of the feeding head has a first thread on its inner wall, and the front end of the injection tube has a second thread on its outer wall. The feeding head and the injection tube are spirally connected by the first thread and the second thread.

7. A pediatric nursing medication feeding device according to claim 1, characterized in that: The injection tube has auxiliary plates on both sides of its outer wall at the tail end, which facilitate the pushing of the push rod.
