Technical Field
[0001] The present invention relates to the technical field of medical devices, in particular to a device for assisting in placing a gastric tube under general anesthesia. Background Art
[0002] Gastric tube (nasogastric tube, nasogastric feeding tube) is inserted through the nostril, through the pharynx, and through the esophagus to the stomach. It is mostly used for gastrointestinal decompression, and can also be used to inject liquids into the stomach to provide patients with necessary food and nutrition. During nursing, care should be taken to avoid gastric tube contamination and gastric tube prolapse, which may lead to aspiration. Because the gastric tube is very soft, awake patients need to cooperate with swallowing when inserting it. However, sometimes patients undergoing general anesthesia need to insert a gastric tube for the purpose of postoperative gastrointestinal decompression and enteral nutrition due to changes in surgical conditions, such as surgery involving the gastrointestinal tract. The existing anesthesia department has certain disadvantages in the process of assisting the placement of gastric tubes under general anesthesia. During the intubation process, the auxiliary device is invisible and the patient cannot cooperate under general anesthesia, resulting in multiple attempts. When medical staff are delivering the tube, it is still possible to cause damage to the inner wall and mucosa of the human body. For this reason, we propose a device for assisting the placement of gastric tubes under general anesthesia to solve the above problems. Summary of the Invention

[0018] See also Figure 1-5The present invention provides an embodiment of a device for assisting the placement of a gastric tube under general anesthesia, comprising a fixing frame 1, a gastric tube 2 being arranged inside the fixing frame 1, a positioning mechanism 3 being arranged on the outside of the fixing frame 1, and a guiding mechanism 4 being arranged inside the fixing frame 1; the positioning mechanism 3 comprising a wire 301, a camera 302 and a display screen 303; the wire 301 being inserted into the gastric tube 2, the end of the wire 301 being connected to the camera 302, and a display screen 303 being installed on the left inner wall of the fixing frame 1; the guiding mechanism 4 comprising a roller 40 1. A first baffle 402 and a handle 403. A roller 401 is rotatably provided on the right side of the fixing frame 1. A first baffle 402 is provided on the right side of the roller 401. A handle 403 is fixedly connected to the top of the fixing frame 1. The gastric tube 2 is evenly wound on the surface of the roller 401. Before inserting the gastric tube 2, the camera 302 is first placed at the end of the gastric tube 2 through the wire 301, and then the gastric tube 2 is wound on the surface of the roller 401. Then, the gastric tube 2 is inserted into the patient's body, and the specific position of the gastric tube 2 is observed through the display screen 303.
[0019] By setting up the positioning mechanism 3 and the guiding mechanism 4, this device solves the problem that during the intubation process, multiple attempts are required because the auxiliary device is invisible and the patient cannot cooperate under general anesthesia, which may cause damage to the inner wall of the human body tube and mucosa.
[0020] Furthermore, a first fixing rod 404 is fixedly connected to the center position of the right side of the fixing frame 1, the right end of the first fixing rod 404 is threadedly connected to the first baffle 402, the surface of the first fixing rod 404 is movably sleeved with a roller 401, and the right side of the surface of the roller 401 is threadedly connected to the second baffle 405. Figure 3 As shown, this structure is used to evenly wrap the gastric tube 2 around the surface of the roller 401, and then put the roller 401 on the first fixed rod 404. First, the second baffle 405 is rotated to connect with the roller 401 to limit the gastric tube 2, and then the first baffle 402 is rotated to connect with the first fixed rod 404 to limit the roller 401, so that the roller 401 can rotate easily.
[0021] Furthermore, a connecting hole 5 is provided at the center of the surface of the fixing frame 1, and an auxiliary component 6 is provided at the bottom of the connecting hole 5. The auxiliary component 6 includes a guide block 601, a storage groove 602, a ball 603 and a feed port 604. The bottom of the fixing frame 1 is fixedly connected to the guide block 601, and a storage groove 602 is provided inside the guide block 601. Eight sets of ball 603 are rotatably installed inside the storage groove 602. The left side of the guide block 601 is connected to the feed port 604. Figure 5As shown, this structure is used to pour lubricant from the feed port 604 into the storage tank 602. When the gastric tube 2 passes through the connecting hole 5 and the guide block 601, it contacts the ball 603 and drives the ball 603 to rotate. Under the rotation of the ball 603, the lubricant in the storage tank 602 is applied to the surface of the gastric tube 2, thereby facilitating the insertion of the gastric tube 2.
[0022] Furthermore, a limit assembly 7 is provided on the top of the fixing frame 1. The limit assembly 7 includes a second fixing rod 701, a limit plate 702 and a torsion spring 703. The inner wall of the fixing frame 1 is fixedly connected to the second fixing rod 701. The outer side of the second fixing rod 701 is rotatably connected to the limit plate 702. The left and right ends of the second fixing rod 701 are sleeved with torsion springs 703. The two ends of the torsion spring 703 are respectively connected to the fixing frame 1 and the limit plate 702. Figure 6 As shown, this structure is used to rotate the limiting plate 702 outward through the second fixing rod 701 when the roller 401 is placed, so that the torsion spring 703 is deformed. After the roller 401 is placed, the end of the limiting plate 702 is attached to the surface of the gastric tube 2 under the elastic action of the torsion spring 703, thereby limiting the gastric tube 2 and preventing the gastric tube 2 from loosening and falling off.
[0023] Furthermore, a distance measuring component 8 is provided on the surface of the fixing frame 1. The distance measuring component 8 includes a card slot 801 on the surface of the fixing frame 1, a card block 802 is inserted into the card slot 801, a first spring piece 803 is fixedly connected to the surface of the card block 802, and a second spring piece 804 is fixedly connected to the bottom of the second baffle 405. Figure 7 As shown, this structure is used to drive the roller 401 to rotate when the gastric tube 2 is inserted, so that when the roller 401 rotates one circle, the second spring piece 804 contacts the first spring piece 803 and makes a collision sound, which prompts the medical staff to the inserted length and facilitates the judgment of the inserted length.
[0024] Furthermore, the diameter of the second baffle 405 is consistent with that of the first baffle 402, which can limit the position of the limiting plate 702 and prevent the limiting plate 702 from directly contacting the surface of the gastric tube 2. The inner wall surface of the second baffle 405 is smooth. Figure 3 As shown, this structure is used to improve the aesthetics of the device by making the diameter of the second baffle 405 consistent with that of the first baffle 402, and the smooth surface facilitates the positioning of the gastric tube 2 to avoid damage to the gastric tube 2.
[0025] Furthermore, the limiting plate 702 is arc-shaped, and a silicone pad is provided on the bottom end surface of the limiting plate 702 to enhance the service life of the device. Figure 4 As shown, this structure is used to better fit the outer side of the gastric tube 2 by making the limiting plate 702 arc-shaped, thereby improving the limiting effect.
[0026] Working principle: When used, Figure 1 and Figure 3 As shown, before inserting the gastric tube 2, the camera 302 is first placed at the end of the gastric tube 2 through the guide wire 301, and then the gastric tube 2 is wrapped around the surface of the roller 401. Then, the roller 401 is put on the first fixing rod 404, and the second baffle 405 is first rotated to connect with the roller 401 to limit the gastric tube 2. Then, the first baffle 402 is rotated to connect with the first fixing rod 404 to limit the roller 401, so that the roller 401 can rotate easily. Figure 4 and Figure 6 As shown, when the roller 401 is placed, the limiting plate 702 is rotated outward by the second fixing rod 701, causing the torsion spring 703 to deform. After the roller 401 is placed, the end of the limiting plate 702 is attached to the surface of the gastric tube 2 under the elastic action of the torsion spring 703, limiting the gastric tube 2 to prevent the gastric tube 2 from loosening and falling off. When the gastric tube 2 is passed through the communicating hole 5 and the guide block 601, as shown in FIG. Figure 5 As shown, the contact with the ball 603 drives the ball 603 to rotate, and the lubricant in the storage tank 602 is applied to the surface of the gastric tube 2 under the rotation of the ball 603, which facilitates the insertion of the gastric tube 2. Then, the gastric tube 2 is inserted into the patient's body, and the specific position of the gastric tube 2 is observed through the display screen 303, as shown. Figure 7 As shown, when the gastric tube 2 is inserted, the roller 401 is driven to rotate, so that when the roller 401 rotates one circle, the second spring piece 804 contacts the first spring piece 803 and makes a collision sound, which prompts the medical staff to the inserted length and facilitates the judgment of the inserted length. The above is the entire working principle of the present invention.
