Description

Technical Field

[0001] The present invention relates to the technical field of medical devices and their peripheral supporting facilities, and particularly relates to an auxiliary laryngeal mask insertion device. Background Art

[0002] A laryngeal mask is a medical device for airway management and is widely used in the fields of anesthesia and first aid. After the laryngeal mask is inserted, a sealing ring is formed around the patient's laryngeal cavity to establish a gas passage, prevent gas from leaking into the esophagus, and at the same time allow gas to enter the trachea, thereby maintaining the patient's ventilation function.

[0003] In the prior art, the laryngeal mask insertion methods mainly include the following: One method is that medical staff hold the laryngeal mask with one hand in a "pen grip" and lift the patient's neck with the other hand (or lift the patient's mandible with fingers), open the patient's mouth, and push the laryngeal mask along the patient's hard palate to the pharynx; this method has the problem that it is easy to roll the patient's tongue into the empty position of the laryngeal mask bladder, resulting in the inability to insert the laryngeal mask. Another insertion method is that medical staff use the "flipping insertion" - the laryngeal mask bladder faces the patient's nasal cavity, is inserted into the back of the patient's mouth, and then the bladder is rotated so that the empty position of the bladder is behind the patient's tongue root and the laryngeal mask is completely inserted; this method has the problems of complex operation, easy distortion and deformation of the laryngeal mask bladder, and folding in the patient's pharynx, resulting in air leakage and the inability to establish an effective artificial airway. Another common method is that medical staff press the patient's tongue with fingers and insert the laryngeal mask using the first method; this method has the risk that the patient's teeth are likely to scratch the medical staff's fingers, resulting in cross-infection, so it is not suitable for clinical promotion.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The purpose of the present invention is to provide an auxiliary laryngeal mask insertion device to solve the problems existing in the above related technologies, reduce the operation difficulty of laryngeal mask insertion, avoid the laryngeal mask being involved in the patient's tongue during insertion, ensure the laryngeal mask insertion effect, and at the same time avoid harm to the patient during the laryngeal mask insertion process and improve the safety factor of laryngeal mask insertion.

[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0024] Embodiment 1 This embodiment provides an auxiliary laryngeal mask insertion device. Please refer to Figures 1-4 [[ID=2,4]]

[0025] , which includes a grip part 1, a tongue depressor part 2, and a positioning part 3. One end of the tongue depressor part 2 is connected to the grip part 1. The tongue depressor part 2 can be bent and deformed so that the end away from the grip part 1 extends into the patient's oral cavity. The tongue depressor part 2 extending into the patient's oral cavity can contact the patient's tongue, so that the laryngeal mask can be pushed along the tongue depressor part 2 to the patient's oropharynx; the positioning part 3 is slidably connected to the tongue depressor part 2 and the relative position of the two can be fixed, so that the positioning part 3 can abut against the patient's lips, thereby preventing the tongue depressor part 2 from extending too deep into the patient's oral cavity.The auxiliary laryngeal mask insertion device of the present invention, when in use, medical staff can hold the grip part 1, and insert the end of the tongue depressor part 2 away from the grip part 1 into the patient's oral cavity. The tongue depressor part 2 bends and deforms to adapt to the shape of the patient's oral cavity. After the tongue depressor part 2 extends into the patient's oral cavity to a certain depth, slide the positioning part 3 to make it contact with the patient's lips to fix the device and prevent the device from shifting during the subsequent laryngeal mask insertion process; when inserting the laryngeal mask, the laryngeal mask is pushed along the tongue depressor part 2 to the patient's pharynx. Using the auxiliary laryngeal mask insertion device of the present invention can reduce the operation difficulty of laryngeal mask insertion, and at the same time avoid hurting the patient by involving the patient's root of the tongue during the laryngeal mask insertion process, ensure the smooth insertion of the laryngeal mask, and protect the laryngeal mask to enable it to function properly; in addition, with the aid of the auxiliary laryngeal mask insertion device of the present invention, the risk of cross-infection can also be reduced, and the safety factor of laryngeal mask insertion is improved.

[0026] It should be explained here that in this specific embodiment, the tongue depressor part 2 can be inserted into the patient's oral cavity to the uvula, and the tongue depressor part 2 is attached to the surface of the patient's tongue, which is convenient for the laryngeal mask to be pushed to the patient's oropharynx. In practical applications, the depth of the tongue depressor part 2 extending into the patient's oral cavity shall be subject to the specific operation requirements of the medical staff when inserting the laryngeal mask. The structure of the laryngeal mask, the laryngeal mask insertion part, the insertion depth, and the insertion completion standard are all well-known common knowledge to those skilled in the art, and will not be elaborated here.

[0027] Among them, the tongue depressor part 2 has a flat structure with an arc surface, so that the tongue depressor part 2 can fit the surface of the patient's tongue. The tongue depressor part 2 having an arc surface enables it to better fit the patient's tongue, avoid the patient's root of the tongue being involved in the laryngeal mask, ensure the smooth insertion of the laryngeal mask, and enhance the laryngeal mask insertion effect. The tongue depressor part 2 adopts a flat structure, which reduces the occupied space of the tongue depressor part 2, provides sufficient operation space for the smooth insertion of the laryngeal mask, and can also reduce the discomfort caused by the laryngeal mask insertion operation to the patient as much as possible.

[0028] In practical applications, the tongue depressor part 2 can be made of a metal material, and the tongue depressor part 2 can produce elastic deformation when extending into the patient's oral cavity. The metal material has a certain elastic deformation ability, so that the tongue depressor part 2 can produce elastic deformation when extending into the patient's oral cavity, adapt to the shape of the patient's oral cavity, and ensure the smooth extension of the tongue depressor part 2. It should also be noted here that in order to avoid the tongue depressor part 2 from hurting the patient's oral cavity, the end of the tongue depressor part 2 extending into the patient's oral cavity can be set to a semi-circular shape, and the edge can be rounded to avoid the edge of the tongue depressor part 2 from hurting the patient's oral cavity and improve the safety of device use. In order to further improve the safety factor of the tongue depressor part 2, a protective layer can be provided on the outside of the tongue depressor part 2. The protective layer can be made of medical silicone material, which can further improve the safety of tongue depressor use while ensuring that the hygiene factor of the tongue depressor part 2 meets the relevant standards.

[0029] In a specific embodiment of the present invention, the tongue depressor 2 can be made of a memory alloy, such as nickel-titanium alloy, so that the tongue depressor 2 can bend and deform when inserted into the patient's mouth, and can restore its original shape when not in operation, thereby avoiding plastic deformation of the tongue depressor 2.

[0030] In other specific embodiments that can be realized by the present invention, the tongue depressor 2 can also adopt an inflatable structure. When the tongue depressor 2 is in an uninflated state, it can be inserted into the patient's oral cavity. The tongue depressor 2 can be connected to an external air source. After the tongue depressor 2 is inserted into the patient's oral cavity, the tongue depressor 2 is inflated by the external air source so that the tongue depressor 2 can be bent and in contact with the patient's tongue. When the tongue depressor 2 adopts an inflatable structure, the tongue depressor 2 can be set to a shape roughly consistent with the shape of the patient's oral cavity. After the uninflated tongue depressor 2 is inserted into the patient's oral cavity, the tongue depressor 2 is inflated so that it can fit with the patient's tongue, providing convenience for laryngeal mask insertion. The inflatable tongue depressor 2 can be used to adjust the curvature of the tongue depressor 2 by the pressure of the gas filled in to adapt to patients with narrow oral cavity and improve the flexible adaptability of the device.

[0031] In order to allow the uninflated tongue depressor 2 to be smoothly inserted into the patient's oral cavity, in actual application, the tongue depressor 2 can also be made of a plastic material with a certain structural strength and can be deformed, or a guide wire can be built into the tongue depressor 2 to guide the tongue depressor 2 to a suitable position in the patient's oral cavity. It should be explained here that the guide wire in medical devices is a common method used by those skilled in the art and will not be described in detail here.

[0032] Specifically, to enable medical personnel to monitor the insertion depth of the tongue depressor 2 in real time, the tongue depressor 2 is provided with a depth scale 4, thereby improving the device's ease of operation and enhancing its practicality. In practical applications, depth scales 4 can be provided on both sides of the tongue depressor 2 to facilitate medical personnel in observing the insertion depth from different viewing angles, further facilitating medical personnel's operation and improving the device's adaptability. In practical applications, to ensure that medical personnel can observe the depth scale 4, the depth scale 4 can be made of a fluorescent material, allowing it to be clearly identified even in dimly lit environments (such as emergency rooms).

[0033] More specifically, the side of the tongue depressor 2 that can contact the patient's tongue is provided with anti-slip grooves. The anti-slip grooves can ensure stable contact between the tongue depressor 2 and the patient's tongue, prevent the tongue depressor 2 from sliding and dislocating on the surface of the patient's tongue, and help improve the stability of the device and the safety of operation.

[0034] To ensure that the laryngeal mask can be smoothly pushed into the patient's oropharynx, a guiding groove is provided on the side of the tongue-depressing part 2 away from the patient's tongue. The laryngeal mask can slide along the guiding groove to the patient's oropharynx. The guiding groove provides a guiding function for the insertion of the laryngeal mask, preventing the laryngeal mask from tilting during insertion. In this specific embodiment, the guiding groove is a U-shaped groove. To prevent the guiding groove from affecting the movement of the laryngeal mask, in this specific implementation manner, a low-friction coating is provided on the wall surface of the guiding groove to reduce the frictional force between the laryngeal mask and the wall of the guiding groove, ensuring that the laryngeal mask can move smoothly along the guiding groove, reducing wear of the laryngeal mask bladder, and further improving the reliability of laryngeal mask insertion. The low-friction coating can be made of materials such as PTFE.

[0035] Furthermore, the positioning part 3 has a positioning protrusion 5, and the positioning protrusion 5 can abut against the tongue-depressing part 2 to fix the relative position of the positioning part 3 and the tongue-depressing part 2, making the positioning part 3 abut against the patient's lips, fixing the overall position of the device, and preventing the device from falling into the patient's oropharynx.

[0036] In other specific implementation manners achievable by the present invention, the positioning part 3 has an adsorption element, and the adsorption element can adsorb on the tongue-depressing part 2, which can also fix the relative position of the tongue-depressing part 2 and the positioning part 3. It should be noted here that the adsorption element can be a suction cup or a magnetic adsorption element. When a suction cup is used, to ensure the adsorption firmness, multiple suction cups can be provided to enhance the adsorption effect; when a magnetic adsorption element is used, since the tongue-depressing part 2 may not be made of ferromagnetic material, two sets of magnetic adsorption elements with opposite magnetic polarities can be respectively provided at the corresponding positions of the positioning part 3. By sleeving the positioning part 3 slidably on the outside of the tongue-depressing part 2, the two sets of magnetic adsorption elements with opposite magnetic polarities provided on the positioning part 3 are respectively arranged on both sides of the tongue-depressing part 2 to achieve the purpose of fixing the relative position of the tongue-depressing part 2 and the positioning part 3.

[0037] To adapt to different patients, in the specific implementation manners achievable by the present invention, the positioning part 3 can be set as a telescopic structure to adjust the width of the positioning part 3 to adapt to the oral cavity widths of different patients, ensuring that the positioning part 3 can contact the patient's lips and fixing the device of the present invention. When the positioning part 3 is a telescopic structure, the positioning part 3 can simultaneously adopt a split structure. For example, the positioning part 3 includes a positioning ring and multiple groups of positioning plates connected to the positioning ring. The positioning ring is slidably sleeved on the outside of the tongue-depressing part 2. One end of the positioning plate is connected to the positioning ring, and the positioning plate is a telescopic plate. Multiple groups of positioning plates can be telescoped to adapt to the lip shapes of different patients, improving the adaptability of the device.

[0038] Even further, the positioning part 3 is connected with a lip pad, and the positioning part 3 and the lip pad are detachably connected. The lip pad can contact the patient's lips. The lip pad can be made of soft rubber material to reduce the compression of the device on the patient's lips and provide protection for the patient; in addition, the lip pad can be a disposable product to ensure the hygiene and safety of the device.

[0039] It should also be noted that the grip portion 1 has operating lines, which increase the friction between the grip portion 1 and the medical staff's hand, improve the grip stability, and ensure the operational safety of the device.

[0040] In practical applications, an image acquisition element can be provided at the end of the tongue depressor 2 that extends into the patient's oral cavity to capture images of the patient's oral cavity. The image acquisition element can communicate with an external device, such as a mobile phone or an external display using Bluetooth, to transmit images of the laryngeal mask insertion process, facilitating real-time observation of the laryngeal mask insertion process by medical staff for teaching or difficult airway management. An image acquisition element with a built-in lighting function can be used, or a lighting element, such as a micro-LED, can be provided at the same time as the image acquisition element to illuminate the patient's throat for auxiliary observation.

[0041] Example 2 This embodiment provides a device for assisting laryngeal mask insertion. In this embodiment, a bite retainer replaces the positioning portion 3. The insertion depth of the device is automatically fixed after the patient's teeth occlude. The use of the bite retainer is suitable for awake patients. The structure and operating principles of the bite retainer are common knowledge to those skilled in the art and will not be further described here.

[0042] The other structures of the auxiliary laryngeal mask insertion device of this embodiment are the same as those of the first embodiment and will not be repeated here.

[0043] Example 3 This embodiment provides an auxiliary laryngeal mask insertion device. In this embodiment, the tongue depressor 2 can adopt a combined structure. The tongue depressor 2 includes a tongue depressor frame and a tongue depressor surface layer. The tongue depressor frame can bend and deform so that the tongue depressor 2 can bend to adapt to the shape of the patient's mouth when inserted into the patient's mouth. The tongue depressor surface layer is covered on the outside of the tongue depressor frame to prevent the tongue depressor 2 from causing damage to the patient's mouth and tongue. The tongue depressor surface layer is made of elastic material to adapt to the bending and deformation of the tongue depressor frame.

[0044] Among them, the tongue depressor skeleton can adopt the following structural modes: The tongue depressor frame can be made of elastic material so that the tongue depressor portion 2 can be elastically deformed when inserted into the patient's oral cavity. The tongue depressor frame can be made of a material with a certain elastic deformation ability, such as plastic material.

[0045] The tongue depressor frame can also adopt a multi-section structure, comprising multiple connecting rods connected in sequence. Adjacent connecting rods are hingedly connected, so that the tongue depressor portion 2 can bend and deform when inserted into the patient's mouth to adapt to the shape of the patient's mouth. The tongue depressor surface is covered on the outside of the tongue depressor frame to prevent the hinges of adjacent connecting rods from causing damage to the patient's mouth. At the same time, the tongue depressor frame is linked to the handle portion 1, making it easy for medical personnel to control the degree of bending of the tongue depressor portion 2 to adapt to the anatomical differences of the tongues of different patients.

[0046] In addition, the tongue depressor skeleton can adopt a frame structure to make the structure of the tongue depressor skeleton more stable. The tongue depressor skeleton can adopt structures such as a spring frame, a flexible hinge frame, or a composite material elastic frame, so that when the tongue depressor part 2 extends into the patient's oral cavity, the tongue depressor skeleton can bend and deform, enabling the tongue depressor part 2 to smoothly extend into the patient's oral cavity to a certain depth.

[0047] The other structures of the auxiliary laryngeal mask insertion device in this embodiment are the same as those in the first embodiment and will not be elaborated here.

[0048] Embodiment Four This embodiment provides a method for inserting a laryngeal mask, using the auxiliary laryngeal mask insertion device in any of the above embodiments, which specifically includes the following operation steps: Step One: Preoperative Preparation Determine the appropriate length of the tongue depressor part 2 (child / adult model) according to the patient's age.

[0049] Check whether the locking function of the positioning part 3 is normal.

[0050] Step Two: Insertion and Fixation Insert the tongue depressor part 2 along the midline of the tongue to the uvula (scale reference: about 10 - 12 cm for adults).

[0051] Press down the grip part 1 to make the tongue depressor part 2 bend and fit the tongue surface, slide the positioning part 3 to the lip edge and lock it.

[0052] Step Three: Laryngeal Mask Insertion Push the laryngeal mask along the guiding groove to the pharynx, and remove the auxiliary laryngeal mask insertion device after confirming the position of the mask bladder.

[0053] Embodiment Five This embodiment provides a laryngeal mask insertion instrument, including a laryngeal mask and also including the auxiliary laryngeal mask insertion device in any one of Embodiments One to Three.
