Technical Field
[0001] This utility model relates to the field of medical equipment technology, and more specifically, it relates to a novel gastric tube pack. Background Technology
[0002] A gastric tube is a medical tube inserted through the nose or mouth, passing through the throat to the stomach, and is widely used in clinical medicine. The functions of a gastric tube include: It can suction gas and liquid from the gastrointestinal tract, reducing intraluminal pressure and tension, improving intestinal blood circulation, and is used for patients with intestinal obstruction or after gastrointestinal surgery to relieve abdominal distension and pain, and reduce postoperative complications; it provides a channel for delivering liquid food and nutrition to patients who cannot eat orally, such as those who are comatose or have difficulty swallowing, ensuring adequate nutrition and maintaining normal metabolism and physiological functions; it ensures accurate medication intake for patients with difficulty swallowing or unable to take oral medications, as well as those who vomit frequently, allowing the medication to reach the stomach directly to exert its effect; it allows for the analysis of gastric juice extracted through a gastric tube, detecting indicators such as gastric acid concentration and pepsin content, aiding in the diagnosis of gastric diseases, and allowing for observation of the color and amount of drainage fluid in cases of gastrointestinal bleeding, enabling timely detection of bleeding; during general anesthesia, indwelling gastric tubes can reduce the risk of gastric contents reflux into the trachea, ensuring airway access and safety during surgery.
[0003] In clinical settings, single-use gastric tubes are commonly used. After removal, paraffin oil-soaked gauze or cotton balls are applied to the tube for lubrication. However, in actual clinical practice, obtaining separate prescriptions for paraffin oil and the gastric tube is cumbersome, as they are separate medical supplies.
[0004] In addition, patients who come to the outpatient clinic to change their gastric tubes must first obtain a prescription for paraffin oil, then go to the outpatient clinic to pick up the medication, and then return to have the gastric tube changed. This process is cumbersome and places an extra burden on patients. If paraffin oil is not used for lubrication, it will cause pain and discomfort to patients during the insertion of the gastric tube.
[0005] Furthermore, manually applying paraffin oil for lubrication after removing the gastric tube can easily lead to contamination of the tube, making it impossible to ensure sterile insertion to the greatest extent. In addition, the gastric tube insertion process requires the use of various medical supplies, which need to be prepared in advance, resulting in a long preparation time and reducing the efficiency of gastric tube insertion.
[0006] Therefore, the present invention aims to provide a novel gastric tube pack to solve the above-mentioned problems. Utility Model Content
[0007] The purpose of this invention is to provide a novel gastric tube package. This invention utilizes a lubrication chamber containing lubricating fluid, where the gastric tube tip is placed, eliminating the need for additional lubricant application. This simplifies the procedure, saves time, and allows for faster treatment, especially in emergency medical settings. The bag's divider separates the package into a gastric tube bag and an accessory bag, reducing the risk of cross-contamination. A sealing line further divides the lubrication chamber into an insertion chamber and a storage chamber, independently storing the gastric tube tip and lubricating fluid, avoiding contamination from traditional manual lubrication application. This ensures aseptic insertion, reduces the chance of infection, and the accessory bag can store various medical supplies without prior preparation, making it convenient, quick, and efficient, shortening preparation time and improving operational fluency.

[0044] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.
[0045] Example: A novel gastric tube package includes a packaging bag 1, which is made entirely of transparent material to facilitate observation of the medical items inside. The packaging bag 1 contains a lubrication chamber 2, which stores a lubricating fluid 3. The lubricating fluid 3 is specifically paraffin oil, which is non-toxic, non-irritating, and safe for the human body. Even if it enters the gastrointestinal tract, it is generally not digested and can lubricate the intestinal wall and feces, preventing water absorption and thus softening the stool for easier passage. A gastric tube 4 is also located inside the packaging bag 1, with its head positioned within the lubrication chamber 2. This allows medical personnel to directly insert the gastric tube 4 into the patient's stomach, avoiding the need for lubrication with paraffin oil applied to gauze as in traditional procedures. This improves the efficiency of gastric tube insertion and ensures aseptic insertion to the greatest extent possible.
[0046] In this preferred embodiment, a sealing line 5 is provided in the lubrication chamber 2, which divides the lubrication chamber 2 into an independent insertion chamber 6 and a storage chamber 7. The head of the gastric tube 4 is placed in the insertion chamber 6, and the lubricating fluid 3 is stored in the storage chamber 7. This operation allows the lubricating fluid 3 and the gastric tube 4 to be stored independently. When the gastric tube 4 is needed, the sealing line 5 is squeezed open to squeeze the lubricating fluid 3 into the insertion chamber 6, so that the head of the gastric tube 4 is evenly coated with the lubricating fluid 3 to achieve a lubrication effect.
[0047] In this preferred embodiment, the packaging bag 1 is provided with a bag body partition 8, which divides the packaging bag 1 into an independent gastric tube bag 9 and an item bag 10. The gastric tube 4 and the lubrication chamber 2 are located in the gastric tube bag 9. The item bag 10 can also store a variety of medical supplies during the gastric tube 4 insertion operation, eliminating the need to prepare these items in advance, saving preparation time for gastric tube 4 insertion, and further improving the efficiency of gastric tube 4 insertion.
[0048] In this preferred embodiment, the item bag 10 contains sterile gloves 11, treatment towels 18, sterile gauze 19, and labeling stickers 20. The sterile gloves 11, treatment towels 18, and sterile gauze 19 are all individually packaged, and commercially available packaged sterile gloves 11, treatment towels 18, and sterile gauze 19 can be used directly without the need for remanufacturing. By opening the packaging bag 1, the labeling sticker 20 is affixed to the side wall of the end of the gastric tube 4, indicating the insertion time and the person responsible for the gastric tube 4. This helps medical staff to keep track of the gastric tube 4 insertion and to identify the main person responsible for nursing care, thereby further improving the standardization and efficiency of nursing care. Wearing sterile gloves 11 allows for direct handling of the gastric tube 4, improving the efficiency of gastric tube 4 insertion while also saving on departmental consumables.
[0049] In this preferred embodiment, the item bag 10 is equipped with a measuring ruler 12. The measuring ruler 12 can be used to measure the accurate distance from the tip of the patient's nose to the earlobe and from the earlobe to the xiphoid process. This avoids the traditional operation of holding the gastric tube 4 on the patient to measure its length, saving time and allowing for precise control of the distance the gastric tube 4 is inserted into the stomach. Furthermore, the measuring ruler 12 is located inside the item bag 10, ensuring that it is not mixed with other medical supplies and guaranteeing the cleanliness and sterility of all items in the gastric tube package.
[0050] In this embodiment, the measuring ruler 12 is preferably made of paper. The measuring ruler 12 made of paper is inexpensive and can be used for disposable measurement, which effectively improves the convenience and practicality of the overall gastric tube package.
[0051] In this preferred embodiment, medical tape 13 is placed inside the item bag 10. The medical tape 13 helps to fix the gastric tube 4 after it is inserted into the stomach. The medical tape 13 is located inside the item bag 10, so that the medical tape 13 is not mixed with other medical supplies, thus ensuring the cleanliness and sterility of all items in the gastric tube package.
[0052] In this preferred embodiment, the gastric tube 4 is equipped with a connector 14 at its tail end. The connector 14 is used to connect a syringe or other delivery device to meet the patient's nutritional needs or treatment needs.
[0053] In this preferred embodiment, a sealing plug 15 is provided on the connector 14, which can seal the connector 14 and prevent the connector 14 from being contaminated.
[0054] In this preferred embodiment, the head of the gastric tube 4 is provided with multiple side-flow feeding ports 16. There are 3 side-flow feeding ports 16 in the same horizontal direction, and they are arranged in a ring along the side wall of the gastric tube 4. There are 3 groups of side-flow feeding ports 16 in the same vertical direction, and they are arranged at even intervals along the side wall of the gastric tube 4. The multiple side-flow feeding ports 16 can make the liquid food delivery faster and more even, and it is less likely to cause blockage, resulting in a better feeding effect.
[0055] In this preferred embodiment, the gastric tube 4 is fitted with a soft plastic head 17. The soft plastic head 17 is flexible and can be retracted under force, which avoids scratching and damaging the internal gastrointestinal mucosa when the gastric tube 4 is inserted into the stomach. This provides better protection and improves the safety of gastric tube 4 insertion.
[0056] Working principle: When using this gastric tube kit to insert the gastric tube 4, the patient is usually in a sitting position. If sitting is not possible, a supine or lateral position can be used. Next, check if the patient's nasal cavity is clear and if there is any damage to the nasal mucosa. Then, open the item bag 10, take out the measuring ruler 12 to measure the required length of the gastric tube to be inserted, and then squeeze the storage chamber 7 to open the sealing line 5, squeezing the lubricant 3 into the insertion chamber 6. This ensures the tip of the gastric tube 4 is evenly coated with the lubricant 3 for lubrication. After sufficient lubrication, open the gastric tube bag 9 to expose the gastric tube 4, take out the treatment towel 18 from the item bag 10 and place it on the patient's chest. Wear sterile gloves 11 and directly handle the gastric tube. Insert the gastric tube 4 downwards through one nostril. When the gastric tube 4 reaches the marked earlobe position, instruct the patient to swallow to assist the tube 4 into the esophagus. Once the tube 4 is in the esophagus, the insertion speed can be increased appropriately until the target length is reached. If the patient experiences nausea or other discomfort during the process, pause briefly. If coughing or difficulty breathing occurs, remove the tube and reinsert it. Then connect the syringe to connector 14. If gastric fluid can be drawn out and there are no other discomforts, the insertion is successful. Finally, use medical tape 13 to secure the gastric tube 4 at the nose to complete the insertion of the gastric tube 4. Remove the label 20, write the responsible person and insertion time, and attach it to the end of the gastric tube 14.
[0057] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
