Description
技术领域technical field
本实用新型涉及医疗器械技术领域，具体的说，一种能同时进行胃肠减压和空肠营养的分支型肠胃营养减压管。The utility model relates to the technical field of medical devices, in particular to a branch type gastrointestinal nutrition decompression tube capable of performing gastrointestinal decompression and jejunum nutrition at the same time.
背景技术Background technique
胃肠减压术是利用负压吸引和虹吸的原理，将胃肠减压管自鼻腔插入，通过胃肠减压管将积聚于胃肠道内的气体及液体吸出。胃肠减压可减少胰泌素和胆囊收缩素-促胰酶素的分泌，减少胰腺外分泌，并减轻胃肠潴留和腹胀，是治疗急腹症的重要手段之一，可减少胃肠液积聚，减少消化液自穿孔部位漏出，减轻腹胀，改善胃肠道供血，有利于胃肠蠕动的恢复，还可用于上消化道出血、急性弥漫性腹膜炎及腹部大、中型手术，尤其是作消化道吻合术者，可减轻胃肠道的张力，防止胃过度膨胀，减轻吻合口张力，促进吻合口的愈合，也用于急性胰腺炎、急性胃扩张，肠梗阻，胃肠穿孔修补或部分切除术，以及胆道或胰腺手术后。而鼻饲空肠营养管是肠内营养管的一种，通过鼻腔插入一根导管到达空肠上段，然后将配好的营养物质通过这个管道直接注入到空肠，营养物质不经过胃腔，为患者提供肠内营养。Gastrointestinal decompression surgery uses the principle of negative pressure suction and siphon, inserts a gastrointestinal decompression tube through the nasal cavity, and sucks out the gas and liquid accumulated in the gastrointestinal tract through the gastrointestinal decompression tube. Gastrointestinal decompression can reduce the secretion of secretin and cholecystokinin-trypsin, reduce pancreatic exocrine, and relieve gastrointestinal retention and abdominal distension. It is one of the important means for the treatment of acute abdomen and can reduce the accumulation of gastrointestinal fluid , to reduce the leakage of digestive juice from the perforation site, reduce abdominal distension, improve gastrointestinal blood supply, and help the recovery of gastrointestinal motility. It can also be used for upper gastrointestinal bleeding, acute diffuse peritonitis, and large and medium abdominal operations, especially for digestive tract For anastomosis, it can reduce the tension of the gastrointestinal tract, prevent excessive gastric distension, reduce the tension of the anastomosis, and promote the healing of the anastomosis. It is also used for acute pancreatitis, acute gastric dilatation, intestinal obstruction, gastrointestinal perforation repair or partial resection , and after biliary or pancreatic surgery. The nasal feeding jejunum nutrition tube is a kind of enteral nutrition tube. A catheter is inserted through the nasal cavity to reach the upper part of the jejunum, and then the prepared nutrients are directly injected into the jejunum through this tube. The nutrients do not pass through the gastric cavity, providing intestinal nutrition for patients Internal nutrition.
但目前的胃肠营养管有很多的不足及局限性。例如，急性胰腺炎患者由于肠道麻痹腹胀明显，需要立即进行胃肠减压，而另一方面，也需要尽早进行肠内营养，以恢复肠道功能，往往患者需要同时插胃肠减压管和鼻饲营养管，增加患者的痛苦；此外，对于上消化道出血及上消化道梗阻患者，一段时间需要密切观察引流量、引流物颜色等，持续的胃肠减压和胃肠营养，可能要长时间放置，直到患者病情缓解，有时，因患者病情变化，需要重新插入已拔出的胃肠减压管或鼻饲营养管，这些都会增加患者的痛苦及经济负担。But the current gastrointestinal nutrition tube has many deficiencies and limitations. For example, patients with acute pancreatitis need immediate gastrointestinal decompression due to intestinal paralysis and obvious abdominal distension. On the other hand, they also need early enteral nutrition to restore intestinal function. Patients often need to insert a gastrointestinal decompression tube at the same time. In addition, for patients with upper gastrointestinal bleeding and upper gastrointestinal obstruction, it is necessary to closely observe the drainage volume and drainage color for a period of time, and continuous gastrointestinal decompression and gastrointestinal nutrition may require Place it for a long time until the patient's condition is relieved. Sometimes, due to the change of the patient's condition, it is necessary to reinsert the extracted gastrointestinal decompression tube or nasal feeding nutrition tube, which will increase the pain and economic burden of the patient.
发明内容Contents of the invention
为克服上述缺陷，本实用新型设计一种分支型胃肠营养减压管，包括鼻饲营养管和肠胃减压管，鼻饲营养管入口端和肠胃减压管头端相互独立。鼻饲营养管和肠胃减压管有一段公共管壁，该公共管壁由鼻饲营养管的一段中间管壁和肠胃减压管内部管壁粘合而成，作为两管的间隔。In order to overcome the above defects, the utility model designs a branched gastrointestinal nutrition decompression tube, which includes a nasal feeding nutrition tube and an gastrointestinal decompression tube. The inlet end of the nasal feeding nutrition tube and the head end of the gastrointestinal decompression tube are independent of each other. The nasal feeding nutrition tube and the gastrointestinal decompression tube have a section of common tube wall, which is formed by bonding a section of the middle tube wall of the nasal feeding nutrition tube and the inner tube wall of the gastrointestinal decompression tube as the interval between the two tubes.
所述鼻饲营养管全管由顺-聚异戊二烯制作，鼻饲营养管为管腔可扩张和回缩的弹性软管，初始时鼻饲营养管呈回缩状态附着在肠胃减压管上，可以减小插入时管道的直径，最大限度的降低鼻饲营养管对鼻腔的刺激，减轻了患者痛苦及损伤。所述鼻饲营养管管道由不透放射线材质构成，方便透视和造影，便于X线下定位。The whole tube of the nasal feeding feeding tube is made of cis-polyisoprene, and the nasal feeding feeding tube is an elastic hose with a lumen that can be expanded and retracted.

在鼻饲营养管入口端还可以连接有医用单向阀，单向阀只有在针管注射给药时呈开放状态，针管拔出后，单向阀可实现自行闭合，保持密封状态，防止营养液返流。A medical one-way valve can also be connected to the inlet of the nasal feeding nutrition tube. The one-way valve is only open when the needle tube is injected. flow.
所述肠胃减压管全管由强化聚氨酯制作，这样就可以使减压管始终处于开放状态，有利于持续吸引。所述肠胃减压管底端是封闭的，与鼻饲营养管不相通，但外部管壁上有若干吸引孔，可利用负压吸引的原理，将积聚于胃肠道内的气体及液体吸出。The entire tube of the gastrointestinal decompression tube is made of reinforced polyurethane, so that the decompression tube can always be in an open state, which is conducive to continuous suction. The bottom end of the gastrointestinal decompression tube is closed and does not communicate with the nasal feeding nutrition tube, but there are some suction holes on the outer wall of the tube, and the gas and liquid accumulated in the gastrointestinal tract can be sucked out by using the principle of negative pressure suction.
使用时，提前将导丝插入营养管，先在鼻饲营养管出口端涂抹润滑油，然后顺着鼻腔插入，使肠胃减压管插入到胃腔，然后继续插入，在X线的引导下，将鼻饲营养管插入到空肠，然后拔出导丝。需要鼻饲给药时，针管插入单向阀，单向阀呈开放状态，鼻饲营养管的管腔呈扩张状态；给药结束后，针管拔出，单向阀将自行闭合，鼻饲营养管的管腔回缩，管径减小。需要吸引时，通过肠胃减压管进行负压吸引。When using, insert the guide wire into the nutrition tube in advance, first apply lubricating oil on the outlet end of the nasal feeding nutrition tube, and then insert it along the nasal cavity, so that the gastrointestinal decompression tube can be inserted into the gastric cavity, and then continue to insert. A feeding feeding tube was inserted into the jejunum, and the guide wire was pulled out. When nasal feeding is required, the needle tube is inserted into the one-way valve, the one-way valve is in an open state, and the lumen of the nasal feeding nutrition tube is in an expanded state; The cavity retracts and the diameter of the tube decreases. When suction is needed, negative pressure suction is performed through the gastrointestinal decompression tube.
本实用新型总长约140cm，胃肠减压管的长度为80-100cm，鼻饲营养管的长度为120-140cm，表面由下往上依次设有刻度：80cm、100cm、110cm、120cm、130cm、140cm等，标明刻度既可以起到大致知道营养减压管位置的作用，还可以识别营养减压管是否有移位。还可以根据实际需要，加大或减少通道的直径和长度。The total length of the utility model is about 140cm, the length of the gastrointestinal decompression tube is 80-100cm, the length of the nasal feeding nutrition tube is 120-140cm, and the surface is provided with scales from bottom to top: 80cm, 100cm, 110cm, 120cm, 130cm, 140cm etc. Marking the scale can not only roughly know the position of the nutrition decompression tube, but also identify whether the nutrition decompression tube has shifted. It is also possible to increase or decrease the diameter and length of the channel according to actual needs.
本实用新型的优点在于：提供一种分支型胃肠营养减压管，在进行胃肠减压的同时，还可以方便地进行空肠营养，做到一管多用，减轻患者痛苦。初始时鼻饲营养管呈回缩状态附着在肠胃减压管上，只有在鼻饲给药时才呈扩张状态，没有增加插入时管道的直径，最大限度的降低鼻饲营养管对鼻腔的刺激，减轻了患者痛苦及损伤。通过在鼻饲营养管入口处连接医用单向阀，单向阀在针管注射结束后可实现自行闭合，保持密封状态，有效防止营养液返流。The utility model has the advantages of providing a branch type gastrointestinal nutrition decompression tube, which can conveniently perform jejunum nutrition while decompressing the gastrointestinal tract, so that one tube can be used for multiple purposes, and the pain of patients can be alleviated. Initially, the nasal feeding feeding tube was attached to the gastrointestinal decompression tube in a retracted state, and it was expanded only when the nasal feeding was administered, without increasing the diameter of the tube when inserted, which minimized the stimulation of the nasal feeding tube to the nasal cavity and eased the Patient pain and injury. By connecting the medical one-way valve at the entrance of the nasal feeding nutrition tube, the one-way valve can close itself after the injection of the needle tube, maintain a sealed state, and effectively prevent the reflux of the nutrient solution.
