AI Technical Summary
In the prior art, when medical staff put the throat hood into the human throat, they often resist the inside of the patient's mouth or throat due to the thrust tip being squeezed and deformed by the front end of the throat hood, causing the soft tissue of the tongue to sink into the opening of the throat hood, resulting in the problem of being unable to push the throat hood.
A tongue pressing plate with a flexible body is designed to form a channel with the upper palate and soft jaw of the human body through the bending state of the flexible body, so as to prevent the throat hood from being squeezed and deformed, and the travel direction of the throat hood is controlled by the shape characteristics of the concave arc surface.
It effectively avoids the throat hood being squeezed and deformed during the placement process, reduces the difficulty of placement, and improves the success rate of placement, ensuring that the throat hood can enter the human throat smoothly.

Abstract
Description
Technical Field
[0001] The present invention relates to a tongue depressor, and particularly to a tongue depressor having a flexible main body for assisting in placing a laryngeal mask. Background Art
[0002] The existing laryngeal mask is inserted into the tracheal opening of a patient by medical staff from the patient's throat so as to inject oxygen into the patient's body. However, due to the curved structures of the human upper jaw and throat, when medical staff want to insert the laryngeal mask into the human body through the throat, the front end of the laryngeal mask often gets squeezed and deformed by the thrust force, touching the inside of the patient's oral cavity or throat, and causing the soft tissue of the tongue to get into the opening of the laryngeal mask, resulting in a situation where medical staff cannot apply force and cannot push the laryngeal mask. Therefore, there is a need for improvement. Summary of the Invention
[0003] The main object of the present invention is to provide a tongue depressor having a flexible main body for assisting in placing a laryngeal mask.
[0004] To achieve the above object, the tongue depressor for assisting in placing a laryngeal mask of the present invention includes a flexible main body. The flexible main body is in a long and flat shape, having a width W and a thickness D, where 1.5 cm < W < 3.5 cm and 0.05 mm < D < 2 mm. The flexible main body has a bent state and a straight state. With the above structure, when in the straight state, after the flexible main body is placed in the human oral cavity, the flexible main body is subjected to an external force to change from the straight state to the bent state, causing the flexible main body to press down the tongue and form a channel between the flexible main body and the human upper jaw, so that the laryngeal mask can advance along the flexible main body without being squeezed and deformed, and preventing the soft tissue of the tongue from getting into the opening of the laryngeal mask, and smoothly entering the human throat through the channel.
[0005] With the tongue depressor having a flexible main body of the present invention, after the flexible main body is placed in the human oral cavity, the flexible main body is subjected to an external force to change from the straight state to the bent state, thereby forming a channel between the bent tongue depressor and the human hard palate, soft palate and cervical vertebra, so that the laryngeal mask can enter the human throat along the tongue depressor through the channel. In addition, with the shape of the concave arc surface of the tongue depressor being slightly higher at both sides and slightly lower in the middle, the opening part of the laryngeal mask can touch the concave arc surface and enter the human throat along the concave arc surface through the channel. By using the shape characteristics of the concave arc surface to control the advancing direction of the laryngeal mask entering the human throat without being squeezed and deformed, and preventing the soft tissue of the tongue from getting into the opening of the laryngeal mask, the difficulty of placing the laryngeal mask is reduced and the placement success rate is increased. Accordingly, the problem mentioned in the prior art is solved, that is, due to the curved structures of the human upper jaw and throat, when medical staff want to insert the laryngeal mask into the human body through the throat, the front end of the laryngeal mask often gets squeezed and deformed by the thrust force, touching the inside of the patient's oral cavity or throat, and causing the soft tissue of the tongue to get into the opening of the laryngeal mask, resulting in a situation where medical staff cannot apply force and cannot push the laryngeal mask.

[0028] To better understand the technical content of the present invention, the following preferred specific embodiments are provided for illustration. Please refer to the following together Figures 1 to 3 The schematic diagram of the first embodiment of the tongue depressor of the present invention in a straight state, the schematic diagram of the second embodiment of the tongue depressor of the present invention in a straight state, and the schematic diagram of the second embodiment of the tongue depressor of the present invention in a bent state
[0029] As Figures 1 to 3 shown, the tongue depressors 1, 1a of the present invention are used to assist in placing a laryngeal mask on the human larynx. The tongue depressors 1, 1a both include a flexible main body 10. The flexible main body 10 is in a long and flat shape and has a width W and a thickness D, where 1.5 cm < W < 3.5 cm, 0.05 mm < D < 2 mm or 0.05 mm < D < 1.2 mm, and the flexible main body 10 includes a convex arc surface 11 and a concave arc surface 12 opposite to the convex arc surface 11. The flexible main body 10 has a straight state S1 and a bent state S2. According to an embodiment of the present invention, the flexible main body 10 further has a length L, L’, 8 cm < L, L’ < 30 cm, and the flexible main body 10 is made of elastic metal (such as spring steel). When an external force is applied to the convex arc surface 11 of the flexible main body 10, the flexible main body 10 will change from the straight state S1 to the bent state S2. According to a specific embodiment of the present invention, when the flexible main body 10 is subjected to an external force of about 0.95 kgw ± 0.5 kgw, the flexible main body 10 will change from the straight state S1 to the bent state S2
[0030] As Figures 1 to 3As shown, the difference between the first embodiment and the second embodiment of the tongue depressor of the present case is that the tongue depressor 1a of the second embodiment has a hand-held portion 30 for medical personnel to hold, and the hand-held portion 30 is arranged at one end of the flexible body 10. It should be noted here that the width W of the flexible body 10 referred to in the present invention is the widest part of the flexible body 10 itself, even if it is a tongue depressor 1a with a hand-held portion 30, the width W of the flexible body 10 is the widest part of the flexible body 10 itself, excluding the width of the hand-held portion 30. The thickness D of the flexible body 10 referred to in the present invention is the thickest part of the flexible body 10 itself, even if it is a tongue depressor 1a with a hand-held portion 30, the thickness D of the flexible body 10 is the widest part of the flexible body 10 itself, excluding the thickness of the hand-held portion 30. According to a specific embodiment of the present invention, the tongue depressor 1 of the present invention is a slap ruler commonly seen in stationery or toys, or a slap ruler bracelet (see https: / / www.youtube.com / watch?v=MF7QlBfmDBI), that is, a slap ruler that maintains a straight line before being subjected to force and can be bent to a handle or arm after being subjected to force. Alternatively, in another embodiment of the present invention, unlike the previous embodiment, a hand-held portion 30 is provided at one end of the slap ruler of the tongue depressor 1a. According to a specific embodiment of the present invention, the tongue depressor 1, 1a of the present invention may further include a coating layer 20 to coat the flexible body 10. The coating layer 20 may be made of an elastic material, such as silicone or rubber. It should be noted that the thickness D of the flexible body 10 referred to in the present invention does not include the thickness of the coating layer 20.
[0031] Please continue to refer to the following Figure 3 , and refer to Figures 4 to 6 A cross-sectional schematic diagram of the second embodiment of the tongue depressor of the present invention in a straight state inserted into the human throat, a cross-sectional schematic diagram of the second embodiment in a bent state in the human throat, and a cross-sectional schematic diagram of the laryngeal mask being placed in the human throat along the second embodiment of the tongue depressor in a bent state.
[0032] like Figure 4 As shown, when the flexible body 10 is in the straightened state S1, the medical staff 300 can hold the hand-held portion 30 of the tongue depressor 1a with the left hand, and after inserting the flexible body 10 into the human oral cavity 90, the medical staff 300 can apply an external force F to the convex arc surface 11 of the flexible body 10 of the tongue depressor 1a, or use the external force generated by the collision between the convex arc surface 11 and the teeth, so that the flexible body 10 can be turned from the straightened state S1 to Figure 5 The bent state S2 shown in the figure allows the flexible body 10 in the bent state S2 to abut against the tongue 94, so that the flexible body 10 in the bent state S2 and the human oral cavity 90 form a channel 100 for the laryngeal mask 80 to enter the human throat 93 along the flexible body 10 through the channel, thereby forming Figure 6According to a specific embodiment of the present invention, the external force is about 0.95 kgw±0.5 kgw, but the present invention is not limited thereto, as long as the external force can make the flexible body 10 change from the straight state S1 to the bent state S2.
[0033] More specifically, if Figure 3 and Figure 6 As shown, the concave arc surface 12 of the flexible body 10 in the bending state S2 forms the channel 10 with the hard palate, soft palate and cervical vertebra of the human body. The concave arc surface 12 is slightly higher on both sides and slightly lower in the middle, so that the opening 81 of the laryngeal mask 80 can contact the concave arc surface 12 and enter the human throat 93 through the channel 100 along the concave arc surface 12. The shape characteristics of the concave arc surface 12 are used to control the direction of the laryngeal mask 80 entering the human throat 93, so as to reduce the difficulty of placing the laryngeal mask 80 and increase the success rate of placement.
[0034] Please refer to the following Figures 7 to 10 A stereoscopic view and a schematic diagram of the tongue depressor in use of the third embodiment of the present invention, a cross-sectional schematic diagram of the third embodiment in use inserted into the human throat, a cross-sectional schematic diagram of the third embodiment in a bent state in the human throat, and a cross-sectional schematic diagram of the laryngeal mask being placed in the human throat along the third embodiment of the tongue depressor in a bent state.
[0035] like Figure 7 As shown, the tongue depressor 1b of the third embodiment of the present invention further includes a fold 40 provided on the flexible body 10 at a distance of 1 to 5 cm from the front end, wherein the fold 40 is formed by folding the convex arc surface 11 of the flexible body 10 toward the concave arc surface 12, wherein the fold 40 further divides the flexible body 10 into a first portion 14 and a second portion 15. Before use, the first portion 14 is first bent toward the convex arc surface 11, but due to the limitation of the fold, the flexible body will not be completely bent and curled, and only the first portion 14 will be in a bent state.
[0036] like Figure 8 As shown, in this embodiment, when the flexible body 10 is in use, the medical staff 300 can hold the hand-held portion 30 of the tongue depressor 1b with the left hand and put the flexible body 10 into the human oral cavity 90. When the first portion 14 touches the tissue of the human oral cavity 90, the convex arc surface 11 is subjected to the rebound force F after the first portion 14 contacts the tissue of the human oral cavity 90, so that the second portion 15 of the flexible body 10 is changed from the straight state S1 to Fig. 9 The bent state S2 shown in the figure allows the flexible body 10 in the bent state S2 to abut against the tongue 94, so that the flexible body 10 in the bent state S2 and the human oral cavity 90 form a channel 100 for the laryngeal mask 80 to enter the human throat 93 along the flexible body 10 through the channel, thereby forming Fig. 9In other words, if the flexible body 10 shown in the third embodiment of the present invention is used, the medical staff 300 does not need to apply additional external force to the flexible body 10. The medical staff 300 only needs to put the flexible body 10 of the third embodiment into the human oral cavity 90, and then use the rebound force F after the first part 14 contacts the tissue of the human oral cavity 90 to make the flexible body 10 change from the straight state S1 to the bent state S2.
[0037] When the flexible body 10 changes from the straight state S1 to the bent state S2, Fig.10 As shown, the concave arc surface 12 of the flexible body 10 in the bending state S2 forms the channel 100 with the hard palate, soft palate and cervical vertebra of the human body. By virtue of the shape of the concave arc surface 12 being slightly higher on both sides and slightly lower in the center, the opening 81 of the laryngeal mask 80 can contact the concave arc surface 12 and enter the human throat 93 along the concave arc surface 12 through the channel 100. The shape characteristics of the concave arc surface 12 are used to control the direction of the laryngeal mask 80 entering the human throat 93, so as to reduce the difficulty of placing the laryngeal mask 80 and increase the success rate of placement. This solves the problem mentioned in the prior art that due to the curved structure of the upper jaw and throat of the human body, when medical staff want to put the laryngeal mask into the human body through the throat, the front end of the laryngeal mask is often squeezed and deformed by the thrust and contacts the inside of the patient's mouth or throat, and the soft tissue of the tongue is trapped in the opening of the laryngeal mask, causing the medical staff to be unable to apply force and unable to push the laryngeal mask.
[0038] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
