Abstract

The invention discloses a nutrient solution pushing device, which comprises a drum body, a push rod, a piston head and sliding blocks, wherein the piston head comprises a seal sleeve and an inner core; the second end of the inner core is provided with at least one pair of supporting arms in a mode of extending outwards; each pair of the supporting arms of the at least one pair of supporting arms are arranged on parts, close to periphery of the inner core, in a mode of directly facing to each other; a guide hole is formed in each supporting arm; each sliding block is inserted into the corresponding guide hole in a sliding mode; friction soft pads are arrange at the first ends of the sliding blocks and first holes are formed in the second holes of the sliding blocks; at least one pair of branched sheets are formed at the first end of the push rod; each pair of the branched sheets of the at least one pair of branched sheets are formed at two opposite sides of the first end of the push rod; a second hole is formed in each branched sheet; one of the first holes is in correspondence to one of the second holes; a rigid connecting rod is connected between one of the first holes and one corresponding second hole; and a spring is further supported between the second end of the inner core and the first end of the push rod.

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 ...
