Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a laryngeal mask with a barrier sheet. Background Art

[0002] The laryngeal mask is a special artificial airway management technique, which was successfully developed and used clinically in the mid-1980s and introduced into China in the 1990s. Great progress has been made in the use of laryngeal masks, and the application range is becoming wider and wider. The ventilation mask at the front end of the laryngeal mask is oval, which can wrap the epiglottis and glottis and form a sealed ventilation space above the glottis. Patients can breathe spontaneously through the laryngeal mask or perform controlled ventilation.

[0003] The published patent No. CN209123112U discloses a laryngeal mask with a barrier sheet. During medical treatment, an operator can directly insert the laryngeal mask into the throat of a patient. When the barrier sheet contacts the patient's mouth, it is the maximum insertion state of the laryngeal mask. However, during the use process, the structure of its own laryngeal tube is fixed and cannot adjust the overall bending angle and the size of the laryngeal mask according to different users, so there are great limitations in use. For this reason, we propose a laryngeal mask with a barrier sheet. Content of the Utility Model

[0004] In view of the problems in the prior art, the utility model provides a laryngeal mask with a barrier sheet.

[0005] The technical solution adopted by the utility model to solve its technical problems is a laryngeal mask with a barrier sheet, which includes a bending adapter tube. A threaded through hole is opened at the bottom end of the bending adapter tube, and a threaded connector is threadedly connected inside the threaded through hole. The threaded connector penetrates and is fixedly connected to one end of a laryngeal mask connecting tube. The end of the laryngeal mask connecting tube far from the threaded connector penetrates and is fixedly connected to a rotating connector. The rotating connector is rotatably connected inside a rotating connection groove, and the rotating connection groove is opened inside an adjustable laryngeal mask;

[0006] A rotating clamping part is penetrated and opened on the side wall of the top end of the bending adapter tube, and a pressing clamping part is clamped inside the rotating clamping part. The pressing clamping part is fixedly connected to one end of an oral straight tube. The end of the oral straight tube far from the pressing clamping part is fixedly and penetratedly connected to a flexible bite piece. A barrier sheet is fixedly and penetratedly connected to the side of the flexible bite piece far from the oral straight tube. An external replacement trachea for conveniently controlling ventilation is penetratedly arranged on the side of the barrier sheet far from the flexible bite piece.

[0007] By adopting the above technical solution, first, according to the esophageal sizes of different patients, the threaded through-hole at the bottom end of the corresponding model of the curved adapter tube is connected to the threaded connector at the top end of the laryngeal mask connecting tube. Then, press the button on the side wall of the push-button fastener so that the fastener at the inner end of the push-button fastener contracts and inserts into the rotating fastener opened on the side wall of the top end of the curved adapter tube, and then release to complete the clamping, thus completing the overall splicing of the laryngeal tube. And through the splicing, the overall length of the esophageal tube is reduced, which is convenient for disinfection and cleaning. Subsequently, adjust the angle of the adjustable laryngeal mask according to the surgical requirements. After adjustment, fix the rotating connector by tightening the knob at the top end of the rotating connection groove, thereby fixing the adjustable laryngeal mask at the bottom end of the tube. After inserting the drainage tube through the side wall of the curved adapter tube, the laryngeal mask can be inserted into the patient's esophagus. Place it between the upper and lower dental arches through the flexible occluding piece to reduce tooth contact and wear the oral straight tube. Use the barrier piece to limit the maximum insertion distance of the laryngeal tube to avoid over-insertion and damage to the patient's esophagus. Control ventilation or the patient's spontaneous breathing through the external replacement trachea.

[0008] Specifically, the external replacement trachea, the oral straight tube, the curved adapter tube, the laryngeal mask connecting tube, and the adjustable laryngeal mask are connected through various connection structures to form a complete laryngeal mask structure.

[0009] By adopting the above technical solution, through a convenient detachable connection method, the whole pipeline can be freely connected according to the esophageal sizes of different patients, thereby improving the overall applicable range of the equipment and being convenient for disassembly and assembly and use.

[0010] Specifically, a locking knob for screwing in and abutting and friction-locking the threaded connector is provided on the side wall of the curved adapter tube.

[0011] By adopting the above technical solution, the laryngeal mask connecting tube and the curved adapter tube are more convenient for disassembly and assembly through a threaded connection method. At the same time, by tightening the locking part to abut and fix the two, it is avoided that they are loosened and fall off due to operation during the operation.

[0012] Specifically, an adjustment knob for controlling the rotation and fixation of the rotating connection groove is installed at the top end of the adjustable laryngeal mask.

[0013] By adopting the above technical solution, by rotating the adjustment knob to control the overall rotation of the laryngeal mask or locking it at one end of the laryngeal mask connecting tube, it is convenient to adjust the angle of the laryngeal mask according to different surgical requirements.

[0014] Specifically, a through-hole for inserting the drainage tube is opened on the side wall at the top end of the curved adapter tube.

[0015] By adopting the above technical solution, the drainage tube inserted through the additional through-hole is used to insert a gastric tube to drain gastric juice, preventing gastric distension and reflux aspiration.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the technical solution of this application, through the design of the bending adapter tube, threaded through-hole, threaded connector, laryngeal mask connecting tube, rotating connector, rotating connection groove, adjustable laryngeal mask, rotating clamping part, pressing clamping part, oral straight tube, flexible occlusal part, barrier sheet and external replacement trachea tube, first connect the threaded through-hole at the bottom of the corresponding model of the bending adapter tube with the threaded connector at the top of the laryngeal mask connecting tube according to the esophageal size of different patients, and press the button on the side wall of the pressing clamping part so that the clamping part at the inner end of the pressing clamping part contracts and inserts into the rotating clamping part opened on the side wall at the top of the bending adapter tube and then release to complete the clamping, thus completing the overall splicing of the laryngeal tube. And the overall length of the esophageal tube is reduced through the splicing, which is convenient for disinfection and cleaning. Subsequently, adjust the angle of the adjustable laryngeal mask according to the surgical requirements. After adjustment, fix the rotating connector by tightening the knob at the top of the rotating connection groove, and then fix the adjustable laryngeal mask at the bottom of the pipeline. After inserting the drainage tube through the side wall of the bending adapter tube, the laryngeal mask can be inserted into the patient's esophagus. Place it between the upper and lower dental arches through the flexible occlusal part to reduce the wear of the teeth on the oral straight tube. Limit the maximum insertion distance of the laryngeal tube through the barrier sheet to avoid over-insertion and damage to the patient's esophagus. Control ventilation or the patient's spontaneous breathing through the external replacement trachea tube. BRIEF DESCRIPTION OF THE DRAWINGS
