背景技术 Background technique
鼻胃、肠管是通过鼻腔或口腔插管向胃肠内注入营养的装置，现有的肠管和胃管均是单 腔肠管或单腔胃管， 病人手术前或给营养时通常需要插入单腔肠管及单腔胃管分别进行肠 内营养及胃部减压， 肠管及胃管分两次插入给病人带来很大痛苦。 Nasal stomach and intestine are devices for injecting nutrients into the gastrointestinal tract through the nasal cavity or oral cannula. The existing intestines and stomach tubes are single-lumen or single-lumen gastric tubes. The patient usually needs to insert a single cavity before surgery or when feeding nutrition. Intestinal tube and single-lumen stomach tube were used for enteral nutrition and gastric decompression, respectively. The intestine and stomach tube were inserted twice to bring great pain to the patient.
发明内容 Summary of the invention
本发明的目的是提供一种可分离鼻胃肠管， 其使用方便， 并且减轻了插管过程中给病 人造成的痛苦。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a separable nasal gastrointestinal catheter which is easy to use and which relieves the suffering of the patient during intubation.
为了达到上述目的，本发明的技术解决方案为：一种可分离鼻胃肠管，包括胃管、肠管， 胃管外壁设有沿长度方向延伸的用于容纳肠管的弧形槽， 肠管卡在弧形槽内。 In order to achieve the above object, the technical solution of the present invention is: a separable nasal gastrointestinal tube comprising a stomach tube and an intestine tube, wherein the outer wall of the stomach tube is provided with an arcuate groove extending in the longitudinal direction for accommodating the intestine tube, and the intestine tube is stuck Inside the curved groove.
本发明可分离鼻胃肠管， 其中， 所述胃管上沿长度方向依次设有若干个球囊， 各球囊均 由弹性材料制成， 球囊套在胃管上并且球囊上除与弧形槽相对应的部分外均与胃管的外壁紧 密贴合， 紧密贴合的部位形成密封层， 各球囊与弧形槽外壁之间形成膨胀腔， 胃管侧壁上设 有沿长度方向延伸的充气腔， 充气腔上连接有充气管接头， 充气管接头位于胃管外， 密封层 上设有使充气腔与各膨胀腔分别相连通的若干个通气孔。 The invention can separate the nasal gastrointestinal tube, wherein the stomach tube is provided with a plurality of balloons in the longitudinal direction, each of the balloons is made of an elastic material, the balloon is sleeved on the stomach tube and the balloon is removed The corresponding portions of the curved groove are closely adhered to the outer wall of the stomach tube, and the tightly fitting portion forms a sealing layer, and an expansion cavity is formed between each balloon and the outer wall of the curved groove, and the length along the side wall of the stomach tube is provided In the direction of extending the inflation chamber, the inflation chamber is connected with an inflation tube joint, the inflation tube joint is located outside the stomach tube, and the sealing layer is provided with a plurality of ventilation holes for respectively connecting the inflation chamber and each expansion chamber.
采用上述方案后， 本发明可分离鼻胃肠管由于肠管卡在胃管的弧形槽内， 因此使用时 一次即可将胃管、 肠管同时放入人体内， 使用方便并且减轻病人的痛苦。 After adopting the above scheme, the invention can separate the nasal gastrointestinal tube. Since the intestinal tube is stuck in the curved groove of the gastric tube, the stomach tube and the intestinal tube can be simultaneously put into the human body at the same time, which is convenient to use and relieves the suffering of the patient.
另外， 由于胃管上设有球囊， 球囊充气后可将肠管挤出弧形槽， 因此胃部减压完成后 可先将胃管取出， 由于胃管较粗， 胃管取出后可大大缓解病人插管的痛苦。 In addition, since the balloon is provided on the stomach tube, the balloon can be extruded into the arc groove after inflation, so that the gastric tube can be taken out after the gastric decompression is completed, because the stomach tube is thick, the stomach tube can be greatly removed. Relieve the pain of patient intubation.
