The specific embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of the specific embodiment.
Referring to Fig. 1; This EA drip tube comprises: nutritional solution liquid storage pipe 1, Mo Feisi dropper 2, nutritional solution joint 3, nursing pipeline adaptor 4 and breather 5; Wherein, The lower end of China ink Fes dropper 2 and breather 5 is connected to the upper end of nutritional solution liquid storage pipe 1 through pipeline, and the upper end of Mo Feisi dropper 2 is connected with nutritional solution joint 3, and nutritional solution joint 3 is connected on the container that holds intestinal nutrient solution; The upper end of feeding pipeline adaptor 4 is connected to the lower end of nutritional solution liquid storage pipe 1 through pipeline, the lower end of feeding pipeline adaptor 4 with feed pipeline (the interior part of body) (not shown) and be connected.Pipeline between China ink Fes dropper 2 and the nutritional solution liquid storage pipe 1 is provided with flow regulator 6; The pipeline of feeding between pipeline adaptor 4 and the nutritional solution liquid storage pipe 1 is provided with flow regulator 7; Flow regulator 7 comprises: the housing 71 and roller 72 that have skewed slot; This housing 71 is located on the pipeline, controls the tube chamber cross-sectional sizes of local pipeline through roller 72 scroll-up/down in the skewed slot of housing 71 and adjusts the speed that nutritional solution instils.The tube chamber cross section of nutritional solution liquid storage pipe 1 is slightly larger than the pipeline between Mo Feisi dropper 2 and the nutritional solution liquid storage pipe 1 and feeds the cross section of the pipeline between pipeline adaptor 4 and the nutritional solution liquid storage pipe 1; For example the diameter in the tube chamber cross section of nutritional solution liquid storage pipe 1 is 8-15mm; Preferential; The diameter in the tube chamber cross section of nutritional solution liquid storage pipe 1 is 5mm; Make nutritional solution that Mo Feisi dropper 2 flows into nutritional solution liquid storage pipes 1 flow down, feed pipeline thereby avoid getting in the inclusion of air nutritional solution, and get into human body along the tube wall of nutritional solution liquid storage pipe 1; Also be provided with scale on the outer wall of nutritional solution liquid storage pipe 1.Breather 5 and atmosphere, top are equipped with the filter membrane (not shown), filter membrane be arranged so that breather 5 with atmosphere the time mask airborne impurity, antibacterial etc. again, guaranteed the health of nutritional solution; The outside of feeding pipeline adaptor 4 is covered with protective cap 41, sealing and health that assurance and nursing pipeline are connected.
Can find out in conjunction with Fig. 2; In use; To hold the height (nutritional solution container lower end is connected with independent exhaustor) that nutritional solution container 81 hangs on about 1.5m earlier, and use nutritional solution joint 3 to connect, and let the Mo Feisi dropper 2 of lower end hang down naturally then with nutritional solution liquid storage pipe 1; Then upwards fixing breather 5 makes the top end opening of breather 5 be higher than the height of liquid level in the nutritional solution container, prevents that in infusion process because resistance is excessive, the nutritional solution liquid level in the nutritional solution liquid storage pipe 1 constantly rises, and then gets into breather 5 outflows; Use then and feed pipeline adaptor 4 connection nursing pipelines 83; And the position of guaranteeing nutritional solution liquid storage pipe 1 lower end is lower than the position 84 (being the horizontal position of feeding tube in the body) that lies in patient's the intestines and stomach on the sick bed 85; Make to have in the nutritional solution liquid storage pipe 1 to remain with one section nutritional solution liquid level all the time, continue infusion to patient, prevent simultaneously when the gastrointestinal tract internal pressure is too small with less pressure; The nutritional solution liquid level is reduced to below the lower end of nutritional solution liquid storage pipe 1; Thinner pipeline below directly getting into after nutritional solution flows down along nutritional solution liquid storage pipe 1 tube wall, thus bring more air into, influence patient's health.
After installing; Earlier that flow regulator 7 is tight dead; Opening flow regulator 6 again makes nutritional solution get into Mo Feisi dropper 2 and nutritional solution liquid storage pipe 1; China ink Fes dropper 2 is used to observe the speed of dripping of nutritional solution infusion; When nutritional solution (this highly observes through the scale on the outer wall of nutritional solution liquid storage pipe 1) when nutritional solution liquid storage pipe 1 rises to the certain altitude a little more than patient's the intestines and stomach position 84 (being the horizontal position of feeding tube in the body), be adjusted to the predetermined infusion flow-rate of nutritional solution through flow regulator 6 this moment again, slowly opens flow regulator 7 and begin the infusion for patient.
When the gastrointestinal tract internal resistance raises; Liquid infusion speed in the nutritional solution liquid storage pipe 1 can slow down or suspend; But because the upper end of nutritional solution liquid storage pipe 1 is connected with the breather 5 with atmosphere, the pressure of the lower end mouth of pipe that connects Mo Feisi dropper 2 and nutritional solution liquid storage pipe 1 pipeline is constant all the time, thus nutritional solution still at persistent instillation in nutritional solution liquid storage pipe 1; Make the nutritional solution liquid level in the nutritional solution liquid storage pipe 1 begin to raise; Thereby pressure reduction is increased, and when the pressure balance of gastrointestinal tract internal resistance and infusion, liquid level also keeps stablizing gradually; Get into the liquid velocity of human body and the speed of flow regulator 6 settings and reach unanimity, so recovered setting speed patient's nutritional solution infusion.Otherwise; When the gastrointestinal tract internal resistance diminished, the liquid infusion speed in the nutritional solution liquid storage pipe 1 can accelerate, but nutritional solution liquid storage pipe 1 upper end is still at the speed persistent instillation with original setting; Make the nutritional solution liquid level in the nutritional solution liquid storage pipe 1 begin to reduce; Thereby pressure reduction is reduced, and when the pressure of gastrointestinal tract internal resistance and infusion once more during balance, it is stable that liquid level keeps gradually; Get into the liquid velocity of human body and the speed of flow regulator 6 settings and reach unanimity, so recovered setting speed patient's nutritional solution infusion.In whole process, infusion velocity appears: normal → utmost point is slack-off in the short time → normal, or normal → utmost point accelerates in the short time → normal buffer circle, and the speed certain degree ground that makes nutritional solution get into human body is stablized on the plan speed that remains on artificial setting.Under the extreme case, if infusion tube is if stop up in the patient body, nutritional solution can rise in the breather 5, but because the top end opening of breather 5 is higher than the height of liquid level in the nutritional solution container, overflow the unlikely upper end from breather 5 of nutritional solution.
In the infusion process; Can check the height of liquid level through the scale on the nutritional solution liquid storage pipe 1; And then the variation of the pressure in the understanding gastrointestinal tract, when liquid level significantly improves, point out the interior liquid holdup situation of gastrointestinal tract to be tending towards serious; Need to transfer slow even the time-out EA, with the gastrointestinal complication that prevents therefore possibly cause.
More than disclosedly be merely a specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
