Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an esophageal occlusion gastric tube structure with the function of preventing reflux and aspiration. Background Technology

[0002] Patients requiring surgery are at high risk of reflux aspiration during anesthesia, especially during endotracheal intubation under general anesthesia. This is one of the most fatal risks during the induction phase. Due to its severe consequences and extremely high mortality rate, it has been a major challenge for the anesthesiology community since the advent of anesthesia, and a suitable solution remains elusive. The risk of reflux aspiration is also relatively high in other hospital settings, such as: (1) patients in a coma with a full stomach in the emergency room; (2) patients with a full stomach requiring esophageal foreign body removal; (3) patients with esophageal venous bleeding requiring ESD treatment; (4) diabetic patients with poor digestion or even gastroparesis who require elective surgery and are fasting; and (5) patients with a full stomach requiring emergency surgery. In all these cases, anti-reflux aspiration procedures are necessary.

[0003] Currently, when performing the aforementioned surgical procedures on patients, medical staff typically use a nasogastric tube for gastrointestinal decompression to prevent reflux and aspiration. After insertion, the tube allows stomach contents to drain out. Stomach contents can be broadly categorized as thin liquids, viscous liquids, and lumpy solids. Due to its narrow diameter, the nasogastric tube can only drain relatively thin liquids; it cannot effectively drain or block viscous liquids or lumpy solids. While positional changes and the Sellick Maneuver can help to some extent, they cannot completely prevent reflux. It still frequently occurs that stomach contents flow through the esophagus into the mouth and then into the airway, causing serious consequences.

[0004] Furthermore, when medical staff perform gastric tube fixation, they first need to insert the tube through the patient's nostril, through the pharynx and esophagus to the stomach, and then simply fix the end of the tube to the patient's nose with adhesive tape. While this method is simple to operate, it is difficult to effectively secure the tube. When the patient sweats, the adhesive tape easily detaches from the nose, leading to tube dislodgement. Moreover, for patients with sensitive skin, using adhesive tape for fixation can easily cause allergies, damage, and infection, causing significant discomfort. Especially with the gastric tube of this invention having an air bladder at the tip, the air bladder is first deflated and inserted into the stomach through the nostril. During occlusion, it is inflated and pulled upwards, locking the bladder at the cardia of the stomach. In this case, a strong and stable fixation at the nose is even more crucial. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention aims to provide an esophageal occlusion gastric tube structure with anti-reflux and aspiration function. This esophageal occlusion gastric tube structure has a reasonable overall design, simple structure, and convenient operation. The anti-reflux and aspiration gastric tube body can block the cardia during use to prevent reflux and aspiration. In addition, the gastric tube fixing structure can effectively fix the tail end of the anti-reflux and aspiration gastric tube body to the patient's upper lip, making it less likely for the gastric tube to fall off from the patient's nose. At the same time, it can also effectively avoid skin allergies, damage, and infection, providing patients with a better comfort experience.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0034] Reference Figures 1-3 As shown in the figure, an esophageal occlusion gastric tube structure with anti-reflux and aspiration function is presented, including a gastric tube body 100 for preventing reflux and aspiration and a gastric tube fixing structure 200.

[0035] The anti-reflux and aspiration gastric tube body 100 is inserted into the patient's stomach 400 through the nostril and esophagus 300 by medical staff during relevant surgeries, and can prevent reflux and aspiration from occurring in the esophagus 300. The front end of the anti-reflux and aspiration gastric tube body is placed inside the patient's stomach 400, and the tail end is placed outside the patient's nose.

[0036] The gastric tube fixing structure 200 can effectively fix the tail end of the gastric tube body 100, which prevents reflux and aspiration, to the patient's upper lip. The gastric tube fixing structure 200 is set at the position of the patient's upper lip. By using the gastric tube fixing structure 200, the tail end of the gastric tube body, which prevents reflux and aspiration, can be effectively fixed to the patient's upper lip, making it less likely for the gastric tube to fall off from the patient's nose.

[0037] The gastric tube body 100 for preventing reflux and aspiration includes a gastric tube 110 and a cuff structure 120. The gastric tube 110 is used by medical staff to insert into the patient's stomach 400 through the nostril and esophagus 300 when performing related operations on the patient, and the front end can enter the stomach. A decompression hole 111 is provided at the front end of the gastric tube 110, and a suction hole 112 is provided at the tail end of the gastric tube 110.

[0038] The cuff structure 120 is used by medical staff to effectively block the patient's esophagus during relevant surgeries and to prevent reflux and aspiration. The cuff structure 120 is installed on the gastric tube 110.

[0039] The cuff structure 120 includes a cuff 121 and an inflation connector 122. The cuff 121 is used by medical staff to effectively seal the patient's esophagus 300 after inflation during relevant surgeries, and to prevent reflux and aspiration within the esophagus 300. The cuff 121 is positioned near the front end of the gastric tube 110. The cuff 121 is secured to the stomach wall at the cardia of the patient by the gastric tube fixing structure 200, effectively preventing reflux and aspiration.

[0040] The inflation connector 122 can be inflated with a syringe. The inflation connector 122 is connected to the cuff 121 through the inflation tube 123. The inflation tube 123 is located inside the side wall of the gastric tube 110 to facilitate the inflation operation of the cuff 121.

[0041] The cuff structure 120 also includes a pressure sensor for real-time detection of the pressure of the cuff on the side wall of the patient's esophagus during the inflation process. The pressure sensor is connected to the display screen. This structure ensures that the pressure of the cuff 121 is kept within a safe pressure value, thus avoiding harm to the patient.

[0042] The cuff 121 is positioned 10cm from the front end of the gastric tube 110. The maximum diameter of the cuff 121 is 4.5cm. This positioning size and outer diameter can effectively block the esophagus of patients of all ages and effectively prevent reflux and aspiration.

[0043] The esophageal occlusion gastric tube structure with anti-reflux and aspiration function also includes a high-definition camera observation structure 130 that can observe the occlusion status in real time after the cuff effectively occludes the patient's esophagus. The high-definition camera observation structure 130 is set on the gastric tube 110. Using the high-definition camera observation structure 130, medical staff can intuitively observe the occlusion status of the cuff on the patient's cardia through the display screen, effectively avoiding reflux and aspiration.

[0044] The high-definition camera observation structure 130 includes a high-definition camera 131 and a high-definition camera connector 132. The high-definition camera 131 can observe the sealing status of the cuff 121 in real time. The high-definition camera 131 is set at one end of the gastric tube 110 near the cuff 121. The high-definition camera 131 is located 2cm behind the cuff 121, and can observe the adhesion between the cuff and the stomach wall at the cardia.

[0045] The high-definition camera connector 132 is connected to the high-definition camera 131 via a signal connection cable 133. The signal connection cable 133 is located inside the side wall of the gastric tube 110. The high-definition camera connector 132 is plugged into a monitor that allows medical staff to directly observe the obstruction of the patient's esophagus 300.

[0046] The gastric tube fixation structure 200 includes a non-woven adhesive layer 210, a fixation narrow band 220, and a fixation wide band 230. The non-woven adhesive layer 210 has a breathable function and is bonded to the patient's upper lip. The fixation narrow band 220 is used to fix the tail end of the gastric tube 110 to the patient's upper lip. One end of the fixation narrow band 220 is fixed to one side of the upper surface of the non-woven adhesive layer 210, and the other end of the fixation narrow band 220 is a free end.

[0047] The fixed wide band 230 and the fixed narrow band 220 are used to fix the tail end of the gastric tube 110 to the patient's upper lip. One end of the fixed wide band 230 is fixed to the other side of the upper surface of the non-woven adhesive layer 210, and the other end of the fixed wide band 230 is a free end. A fixing clearance hole 231 is provided in the middle of the fixed wide band 230. The width of the fixing clearance hole 231 is greater than the width of the fixed narrow band 220, so that the fixed narrow band 220 can pass through it.

[0048] A first fixing structure 600 for fixing the tail end of the gastric tube 110 to the patient's upper lip is provided at the middle position of the upper surface of the fixing narrow band 220. A narrow band adhesive layer is symmetrically provided on the upper surface of the fixing narrow band 220 and on both sides of the first fixing structure 600. A narrow band release layer is attached to the narrow band adhesive layer.

[0049] A second fixation structure 500 is provided at the middle position of the upper surface of the fixed broadband 230, which is combined with the first fixation structure 600 to effectively fix the tail end of the gastric tube 110 to the patient's upper lip. A broadband adhesive layer is symmetrically provided on the upper surface of the fixed broadband 230 and on both sides of the second fixation structure 500. A broadband peel-off layer is attached to the broadband adhesive layer.

[0050] This technology, which uses pressure control via a pressure sensor, is suitable for all age groups and has a promising future. It can perfectly solve the long-standing clinical problem of reflux and aspiration.

[0051] In summary, the present invention has a reasonable overall design, simple structure, and convenient operation. The anti-reflux and aspiration gastric tube body can prevent the reflux and aspiration of gastric contents. In addition, the gastric tube fixing structure can effectively fix the tail end of the anti-reflux and aspiration gastric tube body to the patient's upper lip, making it less likely for the gastric tube to fall off from the patient's nose. At the same time, it can also effectively avoid the patient's skin allergies and infections, bringing greater comfort to the patient.
