Description

Technical Field

[0001] The utility model relates to the technical field of gastric tubes, in particular to a gastric tube capable of preventing gastric juice from refluxing. Background Art

[0002] Clinically, patients often need to be placed in a gastric tube for some reasons. The gastric tube is usually made of polyurethane or silicone. Depending on the material, polyurethane and silicone gastric tubes should be replaced once a month. When the tube is placed, the gastric tube is inserted from the nostril, through the pharynx, through the esophagus to the stomach, and the general depth is about 45-55cm. This operation can play a role in gastrointestinal decompression, nutritional supplementation, and treatment of gastrointestinal bleeding. It is a common nursing operation that helps patients who cannot swallow to deliver necessary water and food under special circumstances;

[0003] However, there are some risks in leaving a gastric tube. After food is passed into the stomach through the gastric tube, abdominal pressure increases due to coughing, abdominal distension and other factors, and food flows back into the esophagus through the cardia, which can cause a series of consequences such as gastric acid burning, aspiration and choking. Existing preventive measures are aimed at preventing the occurrence of reflux of gastric contents by controlling the increase in abdominal pressure of patients. If the patient has a dangerous situation of aspiration caused by reflux, the sensitivity of medical staff and family members to discover the critical situation and the lag of treatment methods such as suction will still aggravate the patient's lung infection. Moreover, when gastric reflux causes aspiration, the patient will choke and suffocate, making it impossible for the patient to breathe normally, which poses certain safety risks.

[0004] In order to solve the above problems, the present application proposes a gastric tube that can prevent gastric juice reflux. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 A stomach tube for preventing gastric juice reflux comprises a tube body 1, wherein symmetrical cavities 19 are provided inside the tube body 1, both ends of one of the cavities 19 on the tube body 1 are fixedly connected with a stomach tube body 20, one end of one of the stomach tube bodies 20 is fixedly connected with a head end 2, one end of the other cavity 19 on the tube body 1 is fixedly connected with a negative pressure tube 3, and the other end is provided with a side hole 4, the upper end of the negative pressure tube 3 is fixedly connected with a connector 5, the outer wall of the connector 5 is slidably connected with a protective shell 6, the outer wall of the protective shell 6 is fixedly connected with a symmetrical guide block 13, the outer wall of the connector 5 is provided with a guide groove 14 matching the guide block 13, and the outer wall of the connector 5 is provided with a limiting component.

[0025] Specific working principle and implementation method: According to the existing technology, after food is injected into the stomach through a gastric tube, the abdominal pressure increases due to factors such as coughing and abdominal distension, and the food flows back into the esophagus through the cardia, which can cause a series of consequences such as gastric acid burning, aspiration and choking. The existing preventive measures are aimed at preventing the occurrence of reflux of gastric contents in patients by controlling the increase of abdominal pressure in patients. If the patient has a dangerous situation of aspiration caused by reflux, the sensitivity of medical staff and family members to discover the critical situation and the lag of treatment methods such as suction will still aggravate the patient's lung infection. Once it is discovered Or delayed treatment will endanger the patient's life; therefore, there are the technical problems mentioned in the background technology; the above-mentioned scheme is designed to solve the above-mentioned problems; when gastric reflux occurs, by changing the single cavity into a double cavity, adding a negative pressure tube 3, and connecting one end of the negative pressure tube 3 to the negative pressure suction device through a connector 5, when the patient's gastric contents reflux into the esophagus, the negative pressure suction device can be operated to suck out the refluxed material inside the esophagus in time, thereby avoiding the gastric reflux material from continuing to flow upward to cause choking and aspiration and other serious consequences, thereby effectively improving the safety of the gastric tube when in use.

[0026] like Figure 3 and Figure 6 As shown, the limit assembly includes a sliding cavity 7 formed on the outer wall of the connector 5, a limit block 8 is slidably connected to the inside of the sliding cavity 7, a telescopic rod 9 is fixedly connected to the inner wall of the sliding cavity 7, and the other end of the telescopic rod 9 is fixedly connected to the limit block 8. A spring 10 is sleeved on the outer wall of the telescopic rod 9, one end of the spring 10 is fixedly connected to the inner wall of the sliding cavity 7, and the other end is fixedly connected to the limit block 8. A limit groove 11 matching the limit block 8 is formed on the outer wall of the protective shell 6, and a push rod 12 is slidably connected to the inside of the limit groove 11, one end of the push rod 12 is set against the limit block 8, and the other end extends out of the protective shell 6. The medical staff inserts the tube body After being retained in the patient's body, the limit block 8 is pushed to retract into the sliding cavity 7 by pressing the push rod 12. When the limit block 8 is separated from the limit groove 11, the protective shell 6 can be moved toward one side of the negative pressure tube 3. After moving to a certain extent, the connector 5 can be connected to the connecting tube on the negative pressure suction device. After the connection is completed, the protective shell 6 can be moved to the other side. When the limit block 8 is ejected under the action of the telescopic rod 9 and the spring 10, the device can be used normally. The advantage of such a setting is that the connection between the connector 5 and the negative pressure suction device can be more stable, thereby ensuring the normal operation of the device.

[0027] like Figure 5 As shown, there are multiple side holes 4, which are evenly distributed in an array at the lower end of the outer wall of one of the cavities 19 on the tube body 1. By setting the number of side holes 4 to be multiple, the efficiency of the device in sucking out gastric reflux inside the esophagus can be effectively improved.

[0028] like Figure 1As shown, the distance between the lower end of the tube body 1 and the lower end of the gastric tube body 20 is set to 20-25 cm. By setting the distance between the lower end of the tube body 1 and the lower end of the gastric tube body 20 to 20-25 cm, the side hole 4 on the outer wall of the tube body 1 is just located at the lower end of the esophagus, so that the device can more efficiently suck out gastric reflux in the esophagus, and can effectively prevent fluid accumulation in the esophagus, thereby further improving the safety of the gastric tube when in use.

[0029] like Figure 6 As shown, a symmetrical slider 15 is fixedly connected to the outer wall of the push rod 12, and a slide groove 16 matching the slider 15 is provided on the inner wall of the limiting groove 11. When the medical staff presses the push rod 12, the slider 15 provided on the outer wall of the push rod 12 and the slide groove 16 provided on the inner wall of the limiting groove 11 can play a better role in limiting and guiding the push rod 12, thereby effectively preventing the push rod 12 from escaping from the limiting groove 11, thereby effectively ensuring the normal operation of the gastric tube.

[0030] like Figure 2 As shown, the outer wall of the protective shell 6 is fixedly connected to a fixing block 18, and a slot matching the gastric tube body 20 is provided on the fixing block 18. After the medical staff places the gastric tube into the patient's body, the upper end of the gastric tube body 20 can be clamped in the slot on the fixing block 18 to prevent the gastric tube body 20 and the negative pressure tube 3 from being entangled, causing inconvenience to the medical staff and the patient, thereby making the gastric tube more convenient to use.

[0031] like Figure 3 As shown, the inner walls at both ends of the protective shell 6 are fixedly connected with sealing rings 17. The sealing rings 17 arranged on the inner walls at both ends of the protective shell 6 can be made of silicone material. Since the silicone material has good plasticity and cushioning properties, the sealing rings 17 arranged on the inner walls at both ends of the protective shell 6 can better protect the negative pressure tube 3 and the connecting tube on the negative pressure suction device, thereby making the gastric tube more stable when in use.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
