In certain embodiments, the graduation marks are formed by a laser marking process.
In summary, the jejunal nutrient canal dredging assembly 100 of the present embodiment generally operates as follows:
opening the first cap 16, manually withdrawing one end of the pull-out spring 30, and allowing the pull-out spring 30 to pass through the spring passage 12, thereby allowing the pull-out spring 30 to penetrate into the blocked nutrient canal;
when the nutrition tube is blocked, bent or friction force is increased due to the increase of contact area, a switch is turned on, a driving motor positioned in the first mounting part 142 is started, the driving motor drives the spool 22 of the line wheel 20 to rotate, the dredging springs 30 on the spool 22 do rotary motion along with the spool 22, the bulges 28 at the two ends of the spool 22 are erected on the bearing lugs in the second mounting part 144 to freely rotate, and the spool 22 and the housing 24 can move so as to smoothly pull out the dredging springs 30 outwards;
the spring 30 receives the pressure from the first pressing block 1466 and the second pressing block 162 at the spring channel 12, generates larger friction force, and slowly advances by itself while rotating due to the characteristics of the spring 30, so that the knife edge 32 for dredging the head of the spring 30 cuts the blockage in the radial direction, and the purpose of dredging is achieved;
the distance of the dredging spring 30 advancing in the nutrition tube can be identified by dredging the scale marks on the spring 30, so that the damage to a patient caused by too deep depth is avoided;
after dredging is completed, the driving motor is reversed, and the dredging spring 30 can automatically withdraw.
