Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a novel oropharyngeal humidifying tracheal swallowing tube. Background Art

[0002] For anesthetized or comatose patients, the floor of the mouth and pharyngeal muscles that support the tongue to maintain upper airway patency relax, and the tongue will fall backward into the posterior pharyngeal wall, causing upper airway obstruction. In order to maintain upper airway patency, an oropharyngeal airway is usually inserted.

[0003] When anesthetized patients or comatose patients breathe through a trachea, their mouths remain open, causing the oral mucosa to dry out and the resistance of the oral mucosa to decrease, making them prone to dry mouth and thirst. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a novel oropharyngeal humidification tracheal tube, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a new oropharyngeal humidification tracheal tube, including a flange connector, a curved protective member, a water absorption cuff and an electrical device, wherein the flange connector is arranged on the curved protective member, the water absorption cuff is arranged inside the curved protective member, and the electrical device is connected to the flange connector; a threaded hole is provided in the center of the flange connector, and water absorption holes and inflation holes are respectively provided on both sides of the threaded hole, an atomization channel is provided on the top of the threaded hole, and a tooth pad is provided on the back of the flange connector.

[0006] Preferably, the protruding outer edge of the flange connector can prevent the patient from swallowing and inserting too deeply. The tooth pad portion is the occlusal portion that contacts the teeth, and its width is sufficient to contact two to three teeth so that the tooth occlusal pressure can be evenly distributed to the contacted teeth.

[0007] Furthermore, the bending protection piece includes a bending protection sleeve, a breathing tube and a pharyngeal separation piece, the bending protection sleeve is arranged on the tooth pad part, the breathing tube is arranged in the threaded hole, and the pharyngeal separation piece is arranged at the end of the breathing tube.

[0008] Furthermore, the curved protective sleeve is provided with a tooth pad connecting portion and a flexible curved portion, the tooth pad connecting portion is provided on the tooth pad portion, and atomization tube holes are provided on both sides of the flexible curved portion.

[0009] Preferably, the curved protective sleeve is made of medical-grade PVC material, which has little irritation to the patient's oral and throat mucosa, reduces postoperative discomfort, and has good biocompatibility, reduces the risk of infection. At the same time, the curved protective sleeve blocks and protects the various pipes inside it, preventing the internal pipes from scratching the oral wall when the curved protective piece is inserted into the patient's mouth.

[0010] Furthermore, the breathing tube is provided with a threaded portion and a curved portion, a sliding boss is provided at the end of the curved portion, the threaded portion is arranged in a threaded hole, and the threaded portion and the threaded hole are connected by threads, and the breathing tube serves as the main pipeline for maintaining the patient's airway unobstructed.

[0011] Furthermore, a sliding groove is provided inside the pharyngeal separation piece, the sliding boss slides in the sliding groove, and a cuff baffle is provided outside the sliding groove.

[0012] Furthermore, the bending protective member also includes a connecting tube, a sliding tube and an atomizing tube, the connecting tube is respectively connected to the water suction hole and the inflation hole, the sliding tube slides in the connecting tube, one end of the atomizing tube is arranged in the atomizing channel, and the other end of the atomizing tube is arranged in the atomizing tube hole.

[0013] Preferably, when anesthetized patients or comatose patients breathe through a trachea, their mouths remain open, causing the oral mucosa to dry out and the resistance of the oral mucosa to decrease, making them prone to dry mouth and thirst. Water vapor is sprayed onto the patient's oral mucosa through an atomizer tube to alleviate the patient's thirst symptoms.

[0014] Furthermore, the water absorbing cuff is provided with an air-filled layer and a water absorbing layer. When the air-filled layer is not inflated, the water absorbing cuff is accommodated in the curved protective sleeve, and the water absorbing cuff slides on the breathing tube.

[0015] Furthermore, an air guide tube is provided on the air-filled layer, and the air guide tube is provided on the sliding tube on the left side of the bending protective member. A supporting air groove is provided inside the air-filled layer, and the supporting air groove is connected to the air guide tube.

[0016] Preferably, the water-absorbing cuff is located at the root of the patient's tongue. When gas is injected into the inflation layer through the airway tube, the bottom of the water-absorbing cuff will push the pharyngeal separation piece to slide, thereby creating a gap between the pharyngeal separation piece and the curved protective sleeve. The water-absorbing cuff extends from the gap, and the supporting air groove expands after the gas is injected, thereby playing a supporting role.

[0017] Furthermore, a water absorption pipe is provided on the top of the water absorption layer, and the water absorption pipe is provided on the sliding pipe on the right side of the bending protective member. A water collection trough is provided on the water absorption layer, and the water absorption pipe is the lowest point of the water absorption layer.

[0018] Preferably, since the atomizer tube continuously sprays water vapor onto the patient's oral mucosa, excess water in the mouth will gather on the surface of the water absorption layer, and the water will be gathered to the bottom of the water absorption tube through the water collection groove on the surface of the water absorption layer, and then the excess water will be sucked out by the water absorption tube, ensuring that the liquid in the mouth will not flow into the esophagus and respiratory tract.

[0019] Furthermore, the electrical device is provided with a pipeline, the end of the pipeline is provided with a connector, and the connector is provided on the flange connector.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The protruding outer edge of the flange connector can prevent the patient from swallowing and inserting too deeply. The tooth pad is the occlusal part that contacts the teeth. Its width is sufficient to contact two to three teeth so that the occlusal pressure of the teeth can be evenly distributed on the contacted teeth.

[0021] 2. The bending protective sleeve is made of medical-grade PVC material, which has little irritation to the patient's oral and throat mucosa, reducing postoperative discomfort. It also has good biocompatibility and reduces the risk of infection. At the same time, the bending protective sleeve blocks and protects the various pipes inside it, preventing the internal pipes from scratching the oral wall when the bending protective piece is inserted into the patient's mouth.

[0022] 3. When anesthetized patients or comatose patients breathe through a trachea, their mouths remain open, causing the oral mucosa to dry out and the resistance of the oral mucosa to decrease, making them prone to dry mouth and thirst. Water vapor is sprayed onto the patient's oral mucosa through an atomizer tube to alleviate the patient's thirst symptoms.

[0023] 4. The water-absorbing cuff is located at the root of the patient's tongue. When gas is injected into the inflation layer through the airway tube, the bottom of the water-absorbing cuff will push the pharyngeal separation piece to slide, thereby creating a gap between the pharyngeal separation piece and the curved protective sleeve. The water-absorbing cuff extends from the gap, and the supporting gas groove expands after the gas is injected, playing a supporting role.

[0024] 5. As the atomizer tube continuously sprays water vapor onto the patient's oral mucosa, excess water in the mouth will gather on the surface of the water absorption layer, and the water will be gathered to the bottom of the water absorption tube through the water collection groove on the surface of the water absorption layer. The excess water will then be sucked out by the water absorption tube to ensure that the liquid in the mouth will not flow into the esophagus and respiratory tract. BRIEF DESCRIPTION OF THE DRAWINGS
