Description

technical field

[0001] The invention relates to a medical device, in particular to a nutrient solution pusher. Background technique

[0002] Patients with gastric tube intubation need to use the nutrient solution pusher to push the nutrient solution into the patient's stomach through the gastric tube. The nutrient solution should not be too fast during the pushing process. Pushing the nutrient solution too quickly can easily lead to excessive stomach capacity in a short period of time, resulting in gastric dilation, reflex hypotension, and decreased heart rate; in addition, it is easy to cause vomiting, food reflux, aspiration, and aspiration pneumonia. Contents of the invention

[0003] In view of the above problems, the present invention aims to propose a nutrient solution pusher, when the user pushes the nutrient solution too fast, the pusher can automatically decelerate.

[0004] For this reason, the present invention proposes a kind of nutrient solution pusher, and ...
