The utility model belongs to the technical field of medical equipment, in particular to a gastric tube which can adjust the elasticity of the tube wall through inflation and ventilation. The bottom section of the gastric tube wall is composed of two thin inner and outer layers. The distance between the inner and outer walls is 0.8-1.0 mm. The inner and outer walls are connected by soft and dense threads to form a wall cavity of the gastric tube. The wall cavity of the gastric tube encircles the cavity of the gastric tube. The wall cavity of the gastric tube is also provided with a longitudinal multi-side pore injection trachea, and the injection trachea is upward to the top of the gastric tube along the inside of the wall of the gastric tube. The outer end of the gas injection pipeline is connected with a one-way valve. The utility model can control the hardness and elasticity of the gastric tube wall by changing the structure of the gastric tube wall which causes adverse reactions of the patients, so as to ensure the sufficient strength and elasticity of the gastric tube when the gastric tube is needed to work, and obviously reduce the strength and elasticity of the gastric tube wall during the intermission to alleviate the stimulating effect on the mucosa of the corresponding parts, and alleviate the serious uncomfortable reaction of the patients caused by the indwel

一种可经充气与泄气调节管壁弹性的胃管
本技术属于医疗设备
,具体涉及一种可经充气与泄气调节管壁弹性的胃管。
技术介绍
临床治疗中,在临床治疗肠梗阻、消化道穿孔、急性胰腺炎等各种急腹症、经胃管鼻饲、各种胃肠道手术前准备时,需常规将胃管从鼻腔经咽喉等路径置入胃内,即可通过外接负压吸引装置,将胃腔内容物排出,从而达到缓解患者症状、预防患者因呕吐导致误吸等治疗效果,也可经此管予鼻饲;但是在临床观察中,患者在置入胃管治疗措施过程中,绝大部分患者出现明显抗拒置入胃管行为,有的患者在胃管置入后出现严重恶心呕吐等不适反应,甚至违抗医嘱自行拔除胃管,即使患者勉强接受了胃肠减压治疗措施,在胃管留置过程中,经常抱怨咽喉不适等,严重干扰患者心情,尤其影响患者睡眠,影响治疗效果,患者配合治疗顺应性明显不足。导致患者不适反应的主要原因:(1)在人体鼻、咽喉部粘膜正常情况下基本无硬物刺激,对外界刺激普遍敏感,反应敏感。(2)目前临床所需要使用胃管,无论是为胃肠减压或鼻饲作用,为保持管腔通畅,胃管壁就必须达到一定硬度、弹性以支撑胃管腔形状,若管壁太软,管腔塌陷,胃管腔塌陷,影响治疗效果。( ...
