Problems solved by technology

[0003] During use, the throat generally needs to be connected to the gas supply device through a connecting joint, but the existing connection between the connecting joint and the throat is relatively thin and unstable, and it is easy to cause the joint to be damaged due to external force. If it is separated from the throat, the air supply to the patient will be interrupted, which will bring hidden dangers to the operation, and if the connection between the connecting joint and the throat is too complicated, it will affect the doctor's rescue of the patient; moreover, the existing throat When the mask is in use, the gas exhaled by the patient contains a lot of water vapor produced by breathing, and the water vapor is discharged out through the throat along with the gas exhaled by the patient, and the gas passes through the connecting joint during the process of discharging. , since the connecting joint is in the outside air, water vapor will condense into water droplets when it is cold inside the connecting joint. As the operation progresses, more and more water droplets will accumulate on the inner wall of the connecting joint. In view of the above, we provide a medical device with a reliable connection between the throat and the connecting joint and which can clean the water droplets in the connecting joint. laryngeal mask

Embodiment 1

[0045] Embodiment 1, a medical laryngeal mask, includes a throat 1 and a cuff 2 is connected to the opening of the front section of the throat 1, and the cuff 2 is connected to an inflatable tube 3. It is characterized in that the other end of the throat 1 is connected to a cylinder A tube 4, the throat 1 is longitudinally provided with an air passage 5 and a drainage channel 6, and the air passage 5 and the drainage channel 6 communicate with the cylindrical tube 4 respectively, and the end of the cylindrical tube 4 away from the throat 1 is provided with a drainage channel seal device, the cylindrical barrel 4 is horizontally slidably connected with a connecting pipe 7 matching with the air passage 5 and a positioning device is arranged in the cylindrical barrel 4, and an unlocking device is provided at the sliding matching part of the connecting pipe 7 and the cylindrical barrel 4, so The connecting pipe 7 passes through the side wall of the cylindrical tube 4 and extends ou...

Embodiment 2

[0051] Embodiment 2, on the basis of Embodiment 1, the annular ring 9 includes a first circular ring 13 and a second circular ring 14 arranged transversely and concentrically, and the first circular ring 13 and the second circular ring 14 are arranged vertically The two sides are fixedly connected by U-shaped sliders 15, and the two rings are laterally slidably connected to the inner wall of the connecting pipe 7 through two U-shaped sliders 15, and the inner wall of the connecting pipe 7 is provided with a rectangular slideway that is slidably matched with the U-shaped sliders 15 16. Two first rectangular sliding rails 17 are fixedly connected to the semicircular ring on the longitudinal side of the first circular ring 13 at intervals along its diameter direction, and the arc-shaped scraper 10 is slidably fitted to the corresponding first In the rectangular slide rail 17, the two arc-shaped scrapers 10 and the first circular ring 13 are slidingly fitted and spaced from the sec...

Embodiment 3

[0053] Embodiment 3. On the basis of Embodiment 2, the drive device includes: the first ring 13 and the second ring 14 are respectively fixedly connected with connecting rods 19 through their circle centers, and the center positions of the two connecting rods 19 are fixedly connected with inner rings. Threaded cylinder 20, the internally threaded cylinder 20 is fitted with a drive screw 21 that is rotatably mounted on the connecting pipe 7 and coaxially arranged with the connecting pipe 7 through threads, and the drive screw 21 is driven by a motor 22 fixed in the transfer chamber 8 , the motor controller is electrically connected to the microcontroller.

[0054] When this embodiment is in use, how the driving device works will be described in detail below; the first circular ring 13 and the second circular ring 14 are respectively fixedly connected with connecting rods 19 and the two connecting rods 19 through their center positions. The central part is fixedly connected with...

Abstract

The invention relates to a medical laryngeal mask. The invention effectively solves the problem that the existing laryngeal mask cannot realize the connection between the connecting joint and the throat pipe more stably and cannot clean the water droplets in the connecting joint; the technical solution includes: A positioning device is provided in the tube and a quick unlocking device is provided on the connecting joint, so that the connection between the throat of the medical laryngeal mask and the connecting joint is simple and convenient, and the installation and disassembly of the connecting joint and the throat can be realized relatively quickly. It saves time for the operation. Furthermore, by installing a water drop cleaning device in the connection joint, the water droplets that adhere to the inner wall of the connection joint placed in the outside air due to cold are discharged from the connection joint, avoiding the accumulation of water droplets. The occurrence of reflux into the patient's trachea greatly improves the safety and reliability of the medical laryngeal mask.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and more specifically relates to a medical laryngeal mask. Background technique [0002] The laryngeal mask is a ventilation device used in surgery. The laryngeal mask can quickly establish an artificial airway to ensure the smooth progress of the operation. The laryngeal mask has the advantages of high success rate of placement, less stimulation to the human body, and convenient operation. Widely; in the prior art, the laryngeal mask mainly includes a cuff, a throat connected to the cuff at one end and an inflatable tube communicated with the cuff, the cuff is provided with a vent hole communicated with the throat, and the cuff inflatable tube The other end is provided with an inflation valve, and the cuff in the deflated state is inserted into the patient's throat, and by inflating the inflation valve, the cuff is inflated and pressed against the patient's throat, so that the patien...
