Abstract
Description
Technical Field
[0001] This utility model relates to the field of laryngeal masks, and in particular to a laryngeal mask with suction function. Background Technology
[0002] A laryngeal mask airway (LMA) is a special artificial airway management tool mainly used to establish a safe airway during general anesthesia. It consists of an inflatable leaf-shaped mask and a connecting tube. The cuff seals the esophagus and pharynx, allowing ventilation through the larynx, avoiding the damage and discomfort of endotracheal intubation. The front ventilation mask of the LMA is oval-shaped and can wrap around the epiglottis and glottis, forming a sealed ventilation space at the glottis. Patients can breathe spontaneously through the LMA or control ventilation. The LMA seals the esophagus and pharynx through the cuff, ensuring airway sealing and ventilation effectiveness.
[0003] Most existing laryngeal masks have simple structures and limited functions, lacking good auxiliary capabilities. They are not convenient enough when patients need to clear sputum, and blocked sputum can easily cause airway obstruction, affecting normal gas exchange. At the same time, existing laryngeal masks do not have the ability to be disassembled and separated independently, which limits the applicability of the laryngeal mask and reduces its practicality. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content
[0004] The purpose of this utility model is to provide a laryngeal mask with suction function, including a device body. The device body includes a connector, a laryngeal mask airbag, a lower tube, an upper tube, a connecting component, and an auxiliary component. The laryngeal mask airbag is conductively connected to the connector. An air tube is provided on one side of the laryngeal mask airbag and a one-way valve is provided at the outer end of the air tube. The lower tube is conductively connected to the other side of the connector. The upper tube is located at the upper end of the lower tube. A connecting component is provided between the lower tube and the upper tube. An external interface is provided at the top of the upper tube. The auxiliary component is located on one side of the lower tube.
[0005] Furthermore, the connecting assembly includes an inner conduit and an outer conduit. The inner conduit has a central ring in the middle of its outer side and sealing protrusions at both ends. The inner side of each end of the outer conduit has a set of limiting rings.
[0006] Furthermore, the auxiliary component includes a side tube and an auxiliary tube. The side tube is connected to one side of the lower catheter, and the auxiliary tube is connected to the outside of the side tube. The upper end of the auxiliary tube is provided with a suction port.
[0007] Furthermore, the inner conduit is sealed between the lower and upper conduits by sealing protrusions at both ends. The lower and upper conduits are respectively provided with a lower locking groove and an upper locking groove on their outer sides, and the limiting rings on both sides of the outer tube are respectively fitted into the lower locking groove and the upper locking groove.
[0008] Furthermore, the upper end of the side pipe is provided with an internal thread, the lower end of the auxiliary pipe is provided with a threaded head and the threaded head is screwed into the internal thread, and a sealing gasket is provided between the side pipe and the auxiliary pipe.
[0009] Furthermore, a connecting strip is provided at the upper end of the suction port, and a sealing plug is connected to the other end of the connecting strip, with the sealing plug corresponding to the suction port.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 As shown in Figure 4, this embodiment provides a laryngeal mask with suction function, including a device body 1. The device body 1 includes a connector 2, a laryngeal mask airbag 3, a lower tube 4, an upper tube 5, a connecting component 7, and an auxiliary component 8. The laryngeal mask airbag 3 is electrically connected to the connector 2. A ventilation tube 31 is provided on one side of the laryngeal mask airbag 3, and a one-way valve 32 is provided at the outer end of the ventilation tube 31. The lower tube 4 is electrically connected to the other side of the connector 2. The upper tube 5 is provided at the upper end of the lower tube 4. A connecting component 7 is provided between the lower tube 4 and the upper tube 5. An external interface 6 is provided at the top of the upper tube 5. The auxiliary component 8 is provided on one side of the lower tube 4.
[0023] Preferably, the connecting assembly 7 includes an inner conduit 71 and an outer conduit 74. The inner conduit 71 has a central ring 72 in the middle of its outer side and sealing protrusions 73 at both ends. The inner side of both ends of the outer conduit 74 is provided with a set of limiting rings 75. The two ends of the inner conduit 71 are sealed and inserted between the lower conduit 4 and the upper conduit 5 through the sealing protrusions 73. The lower conduit 4 and the upper conduit 5 are respectively provided with a lower groove 41 and an upper groove 51 on their outer sides. The limiting rings 75 on both sides of the outer conduit 74 are respectively fitted into the lower groove 41 and the upper groove 51.
[0024] The inner conduit 71 is sealed between the lower conduit 4 and the upper conduit 5 by the sealing protrusion 73. The outer sleeve 74 is fitted onto the connection between the lower conduit 4 and the upper conduit 5, and the limiting ring 75 is engaged in the lower slot 41 and the upper slot 51. This enables the sealing and disassembly of the lower conduit 4 and the upper conduit 5, making it easy to disassemble or connect the two sets of conduits and to disassemble and replace the conduits individually. The operation is simple and convenient, improving the practicality of the device.
[0025] Preferably, the auxiliary component 8 includes a side tube 81 and an auxiliary tube 83. The side tube 81 is connected to one side of the lower catheter 4, and the auxiliary tube 83 is connected to the outside of the side tube 81. The upper end of the auxiliary tube 83 is provided with a suction port 86. The upper end of the side tube 81 is provided with an internal thread 82. The lower end of the auxiliary tube 83 is provided with a threaded head 84, and the threaded head 84 is screwed into the internal thread 82. A sealing gasket 85 is provided between the side tube 81 and the auxiliary tube 83. The upper end of the suction port 86 is provided with a connecting strip 87, and the other end of the connecting strip 87 is connected to a sealing plug 88, and the sealing plug 88 corresponds to the suction port 86.
[0026] The auxiliary tube 83 is connected to the side tube 81 via the internal thread 82 and the threaded head 84. The auxiliary tube 83 is connected to the lower tube 4 via the side tube 81. The suction port 86 is opened and closed by the sealing plug 88, thereby enabling assisted suctioning of the patient's throat. This facilitates maintaining airway patency, timely clearing of sputum in the airway, preventing sputum from blocking the airway, ensuring normal gas exchange, and improving the practicality of the device.
[0027] The working principle and usage process of this utility model are as follows: First, select a suitable upper tube 5. Connect the upper tube 5 and lower tube 4 through the sealing protrusion 73 and the inner tube 71. Connect the laryngeal mask to the external equipment through the outer interface 6. Cover the outer tube 74 on the outside of the upper tube 5 and the lower tube 4 so that the limiting ring 75 is tightened in the lower slot 41 and the upper slot 51 respectively. At this time, the laryngeal mask can be used. When it is necessary to perform assisted suctioning, the auxiliary tube 83 can be connected to the inner thread 82 through the threaded head 84 so that the auxiliary tube 83 is connected to the side tube 81. Then, open the sealing plug 88 and suction air through the suction port 86 to complete the assisted suctioning operation.
