Background technique

At present, it is very troublesome to give medicine to infants and young children. It is often difficult to control the dosage of medicines by feeding them with ordinary medicine spoons. Currently, there is a commonly used oral medicine injection hose because It is not good to control the length of the extension. The tube head will often move to the base of the tongue, causing vomiting. The liquid will often enter the trachea directly, resulting in sputum. On the other hand, when feeding a psychiatric patient, a spoon is usually used to deliver the liquid to the patient. However, because such patients are unconscious and unwilling to cooperate with the treatment, the liquid is easily spilled, which is not conducive to the recovery of the patient. It also increases the workload of medical staff. Therefore, a number of structurally different feeders have emerged.

Let it normally suck the warm water of the nozzle and swallow it normally. Push it slowly into the piston during the process of sucking warm water. The liquid enters the mouth and mixes with warm water and is swallowed. Continue to swallow warm water and push the liquid until the drug is pushed out, and the warm water will rinse the oral residual liquid. Feeding is completed; B: For younger infants, the basic principle of feeding is the same as that of large children. The difference is to use nipple-like nozzles and induced feeding methods. The feeding method is as follows: firstly let the overflowing warm water (including sweetness) induce the suction in the child's mouth, and then slowly push the medicine when the normal suction is allowed; when the child stops the suction, stop pushing the medicine immediately. When the suction is allowed again, push the liquid again; cycle until the liquid is pushed out. The invention has undergone systematic comprehensive clinical trials, and can completely achieve no bitterness and no odor for children taking the powder, and unknowingly swallows the drug in the process of absorbing warm water.
