The invention discloses a gastrointestinal catheter, which comprises a main pipe. The end of the main pipe is provided with a head and the head is a solid ball structure. The end of the head is provided with grooves. The two sides of the groove and the bottom of the groove are provided with a number of drainage holes connected with the outside of the head. The main pipe is provided with an inner tube closed by the end, and the head and the inner tube are retained between the main pipe and the inner tube. The end part of the inner tube is arranged in the groove, and the lower part of the inner pipe is provided with a through hole. Compared with the prior art, the invention can discharge the air in the inner tube and the main pipe when injecting fluid into the inner tube. The fluid in the inner tube enters the main pipe through the through hole, and then draws the end of the inner tube out of the groove of the head. The fluid can enter the intestine and stomach through the drainage hole on the head, thus avoiding the pressure of air into the intestine when feeding or feeding medicine. Abdominal distension caused by stomach can prevent gastrointestinal dilatation and promote the recovery of gastrointestinal function.
【技术实现步骤摘要】
一种肠胃导管
本专利技术涉及肠胃疾病的治疗设备,特别是一种肠胃导管。
技术介绍
目前消化系统疾病病人如需手术治疗,为了防止患者在手术中由于麻醉影响而产生呕吐、窒息,便于术中的操作和增加手术安全性,一般在手术前会插一根导管到胃中进行胃肠减压;术后为了减轻缝线张力和切口疼痛,利于腹部伤口愈合,减轻胃肠道内压力,促进胃肠功能尽快恢复,防止腹胀,也会留置一根导管在胃中;另外某些饮食不能自理、深度昏迷的危重病人,为了正常的生理机能也会留置一根导管在胃中或者肠道中,以帮助病人饮水、进食和喂药。然而在通过肠胃导管进行喂食或喂药时,流体通常会将导管内的空气压入到肠胃中,容易引起腹胀,和胃肠道扩张,影响胃肠道血液循环,降低胃肠道功能的恢复。
技术实现思路
本专利技术的目的是要提供一种肠胃导管,避免了在喂食或喂药时将空气压入肠胃中引起的腹胀现象发生,防止胃肠道扩张,促进胃肠道功能的恢复。为达到上述目的,本专利技术是按照以下技术方案实施的:一种肠胃导管,包括主管,所述主管的端部设有封头,封头为实心球结构,所述封头的端部设有凹槽,凹槽的两侧壁和底部开设若干与封头外部连通的引流孔,所述主管内设有端部封闭的内管,主管和内管之间留有间隙,所述内管的端部设置于凹槽内,内管的下部末段设有通孔。作为本专利技术的进一步优选方案,所述凹槽两侧壁设有密封圈。作为本专利技术的进一步优选方案,所述主管外表面上设置有亲水性超滑涂层。作为本专利技术的进一步优选方案,所述主管上设置有可在X光或CT下显影的显影层。与现有技术相比,本专利技术能够在内管中注入流体时将内管和主管内的空气排出,内管中流体通过通孔进入主管 ...
