Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a transoral gastric tube insertion guide device. Background Technology

[0002] In the treatment of critically ill patients, we often encounter patients with skull base fractures combined with cerebrospinal fluid leakage, nasal trauma, deviated nasal septum, nasopharyngeal carcinoma, massive nasal hemorrhage, etc., where there are contraindications to nasogastric tube placement. However, nasogastric tube placement is an important treatment measure for critically ill patients, such as gastrointestinal decompression, nutritional support, and drug infusion. This necessitates the placement of nasogastric tubes orally.

[0003] In critically ill patients with altered consciousness, laryngeal edema, esophageal intubation, esophagotomy, or inability to cooperate with swallowing, blind insertion of a nasogastric tube via the mouth carries the risk of the tube kinking or coiling in the pharynx, and repeated insertions pose a risk of injury and bleeding. In recent years, video laryngoscopy combined with guidewire guidance and video laryngoscopy-guided esophageal catheterization have been used clinically. However, the nasogastric tube guidewire is flexible and lacks directionality, and esophageal intubation guidance requires inserting the catheter into the esophageal inlet, which can cause esophageal damage. This also consumes nurses' time and energy, exacerbates laryngeal edema, causes mucosal bleeding, and may even lead to other complications.

[0004] In view of this, the present invention proposes a transoral gastric tube insertion guide device. Utility Model Content

[0005] To overcome the aforementioned shortcomings of existing technologies, this invention provides a transoral nasogastric tube insertion guide device. This addresses the issues of blindly inserting a nasogastric tube into the pharynx in critically ill patients with impaired consciousness, laryngeal edema, esophageal intubation, esophagostomy, or inability to cooperate with swallowing. These issues include the risk of the tube kinking or coiling in the pharynx during repeated insertions, and the risk of injury and bleeding from repeated attempts. In recent years, video laryngoscopy combined with guidewire guidance and video laryngoscopy-guided esophageal catheterization have been used clinically. However, the nasogastric tube guidewire is soft and lacks directionality, and esophageal intubation guidance requires inserting the catheter into the esophageal inlet, which can damage the esophagus. This also consumes nurses' time and energy, exacerbates laryngeal edema, causes mucosal bleeding, and may even lead to other complications.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a transoral gastric tube insertion guide device, including a guide tube body, which is used to guide the gastric tube into the patient's body.

[0007] Preferably, the guide tube body has a guide port inside for inserting a gastric tube.

[0008] Preferably, the bottom end of the guide tube body has an outlet.

[0009] Preferably, the diameter of the outlet is 3mm, which is used to expand the guide port.

[0010] Preferably, the side end of the guide tube body is provided with a wire.

[0011] Preferably, the wire is made of rust-proof material.

[0012] Preferably, the wire is made of hard material for shaping.

[0013] Preferably, the outer surface of the wire is provided with a spacing layer to avoid contact between the wire and the esophagus of the patient.

[0014] Compared with the prior art, the utility model has the beneficial effects that:

[0015] The utility model discloses a guide tube body is provided, when using guide tube body, first inserting the stomach tube into the guide mouth inside in preparation stage, and the stomach tube can move in the guide tube body, then under the cooperation of laryngoscope, control guide tube body makes the stomach tube accurate and places into the esophagus, after waiting for the connection to be completed, can take out the stomach tube from the taking -out port, thereby reach the guide tube body is taken down, simultaneously, the guide tube body is the soft material as a whole, when using, in order to be convenient for the control and the adjustment stomach tube direction and angle, the guide tube is shaped through the guide wire, and in order to avoid the guide tube body damage in the bending process simultaneously, the protective layer is set up to the outer layer of the wire, more safe protection guide tube body.
