为了研究胃肠道的生理和营养,愈来愈多的持久性胃导管应运而生。本文介绍的是一种新型的一体化的持久性胃导管。它具有较大的自由度和极少的紧张性,可以大大地改善以往的持久性胃导管的堵塞和渗漏现象。价格便宜,使用简便,并可应用于总摄取热量的研究。胃导管由聚乙烯管、一个顶部球形的灌胃针头和一个静脉注射器的接合器组成。聚乙烯管长15cm,两端分别与球形灌胃针头和
In order to study the physiology and nutrition of the gastrointestinal tract, more and more persistent gastric catheters have emerged. This article describes a new, integrated, and durable gastric catheter. It has greater freedom and less tension, can greatly improve the past persistent gastric duct plug and leakage. Cheap, easy to use, and can be applied to the total calorie intake. The gastric catheter consisted of a polyethylene tube, a top spherical gavage needle and a syringe adapter. Polyethylene tube length 15cm, both ends of the spherical gavage needle and
