Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a novel gastric tube. Background Technology

[0002] A nasogastric tube, also known as a gastric tube, is mainly used to extract gastric juice. It can also be used to inject liquid into the stomach to provide patients with necessary food and nutrition. In clinical practice, nasogastric tubes are needed for nutritional support of critically ill patients, preoperative preparation for surgery of gastrointestinal diseases, and conservative treatment of patients with intestinal obstruction and pancreatitis. They are used to decompress and drain patients or to allow them to eat independently. Currently, nasogastric tubes are fixed externally to the nose and face with tape, which often results in patients pulling out the tube, making them less practical. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a novel gastric tube, including a tube body 1. A counterweight guide head 2 is provided at one end of the tube body 1. Several discharge ports 3 are circumferentially formed along the length of the tube body 1 near the counterweight guide head 2. A fixing component 4 is adjusted and provided on the outer circular wall of the tube body 1. A feeding head 5 is connected to the top of the tube body 1, and a sealing cap 6 is connected to one side of the feeding head 5. When the device needs to be installed in the patient's body, the counterweight guide head 2 guides the tube body 1, and the scale on the surface of the tube body 1 (not shown in the figure) is observed. (Draw), then insert the tube 1 into the patient's stomach, and then connect the external saline injection device to the infusion head 7 in the fixing component 4. The saline is injected into the regulating ring 42 through the external injection device and delivered to the air bag 43 along the guide tube 47. The air bag 43 expands and fits against the inner wall of the gastrointestinal tract to fix the tube 1 and improve its stability. Then, by opening the sealing cap 6, the nutrients are delivered through the infusion head 5 to the outlet 3 side of the tube 1, and finally conveniently guided to the patient's stomach, improving the practicality of the equipment.

[0025] like Figure 3 As shown, specifically, the counterweight guide head 2 is hemispherical, and a counterweight ball 21 is provided in the middle of the counterweight guide head 2. The counterweight guide head 2 is bonded to the end of the tube body 1. By setting the counterweight ball 21 in the middle of the counterweight guide head 2 and setting the end of the counterweight guide head 2 to be hemispherical, it is convenient to guide and install the tube body 1, and improve the convenience of guiding and installing the tube body 1.

[0026] like Figure 2As shown, specifically, the outer circular wall of the tube body 1 is provided with a plurality of slots 101. The outer circular wall of the tube body 1 is provided with threads 102 at both ends of the slots 101. The feeding head 5, the adjusting ring 42 and the fixing ring 41 are respectively connected to the corresponding threads 102 on both sides of the outer circular wall of the tube body 1, thereby adjusting and installing them onto the outer circular wall of the tube body 1.

[0027] Specifically, the discharge port 3 is waist-shaped, and adjacent discharge ports 3 are staggered along the length of the tube 1. By staggering the discharge ports 3 along the length of the tube 1, it is easier to guide nutrients evenly into the patient's stomach cavity.

[0028] like Figure 4 and Figure 5 As shown, specifically, the fixing component 4 includes a fixing ring 41 threadedly connected to the side of the tube 1 near the outlet 3, and an adjusting ring 42 threadedly connected to the side away from the outlet 3. An air bladder 43 is symmetrically connected to the middle of the fixing ring 41. Connecting heads 44 are symmetrically arranged on both sides of the air bladder 43 at the top of the fixing ring 41. A through hole 45 is opened in the middle of the adjusting ring 42. Several connecting heads 46 are arranged in a ring around the top of the adjusting ring 42, connecting to the through hole 45. The connecting heads 46 are connected to the connecting heads 44 via a guide tube 47. By threading the fixing ring 41 and the adjusting ring 42 to the tube 1, it is convenient to adjust the distance between the fixing ring 41 and the outlet 3, as well as the distance between the fixing ring 41 and the adjusting ring 42, according to different patients. The fixing ring 41 is connected to the adjusting ring 42 via the guide tube 47, thus facilitating the injection of saline solution into the air bladder 43. The air bladder 43 inflates, fixing the tube 1 into the gastrointestinal tract, preventing movement and improving stability.

[0029] Specifically, the side wall of the adjusting ring 42 is connected to the through hole 45 and is equipped with an infusion head 7 and a pressure valve 8. The outer circular wall of the connector 44, the coupling 46 and the infusion head 7 are all provided with hemispherical protrusions 9. The inner wall of the guide tube 47 is provided with a groove (not shown in the figure) that engages with the hemispherical protrusions 9. By engaging the groove of the guide tube 47 with the hemispherical protrusions 9 of the connector 44 and the coupling 46, the stability of the installation of the guide tube 47 with the connector 44 and the coupling 46 is improved, thereby improving the stability of nutrient flow.

[0030] Specifically, by symmetrically setting the airbags 43, the two airbags 43 are respectively attached to the inner wall of the gastrointestinal tract on the same side, thereby fixing the fixing ring 41. A certain gap is left between the two adjacent airbags 43, which is conducive to the patient's saliva, esophageal secretions, etc. entering the stomach cavity.

[0031] Specifically, the output end of the external saline injection device is connected to the hemispherical protrusion 9 on the outer wall of the infusion head 7 via a pipe, thereby improving the stability of the saline injection.

[0032] Specifically, the inflation size of the airbag 43 is linearly related to the reading of the pressure valve 8. When injecting saline, the inflation size of the airbag 43 can be determined by observing the reading of the pressure valve 8.

[0033] Specifically, the inner wall of the fixing ring 41 is provided with a plurality of retaining strips 10. When the fixing ring 41 is installed by threaded connection, the retaining strips 10 are engaged with the retaining grooves 101 to further improve the stability of the installation of the fixing ring 41.

[0034] like Figure 6 As shown, specifically, the top of the sealing cover 6 is provided with a handle 11, which facilitates the opening and closing of the sealing cover 6.

[0035] Specifically, the side wall of the tube 1 is marked with graduations. When installing this device, doctors or nurses can observe the graduations on the side wall of the tube 1 to further determine the position of the tube 1 inserted into the patient's body.

[0036] The working principle of this utility model is as follows: In use, the tube body 1 is guided by the counterweight guide head 2, and the scale on the surface of the tube body 1 is observed. Then, the tube body 1 is inserted into the patient's stomach. Then, the external saline injection device is connected to the infusion head 7, and the saline is injected into the regulating ring 42 through the external injection device. It is then transported to the air bladder 43 along the guide tube 47, so that the air bladder 43 expands and fits against the inner wall of the gastrointestinal tract to fix the tube body 1 and improve its stability. Then, by opening the sealing cap 6, the nutrients are transported through the infusion head 5 through the tube body 1 to the outlet 3 side, and finally conveniently guided to the patient's stomach, improving the practicality of the equipment.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
