[0018] The detailed description and technical content of the present invention are described as follows with illustrations:
[0019] See figure 1 , figure 2 , image 3 , Figure 4A and Figure 4B As shown, the present invention is a mouthpiece, which is fixedly placed in a human oral cavity (not shown) in conjunction with a tracheal intubation tube 1. The mouthpiece includes a rigid tube 10 and a covering on the rigid tube 10 of the surface of the elastic covering 20. The rigid tube 10 includes a tube body 11, a channel 12 arranged in the tube body 11, a tongue depressor 13 arranged on one side of the tube body 11, and an occlusal joint adjacent to the tongue depressor 13 The portion 14, a stopper 15 connected to the side of the bite portion 14 away from the tongue depressing portion 13, and an extension portion 16 connected to the side of the stopper 15 away from the bite portion 14. The channel 12 can be used for nursing staff or physicians to perform sputum or corresponding operations; the tongue depressor 13 is used to penetrate deep into the human oral cavity to avoid the situation where the tongue can easily push the mouthpiece and cause the mouthpiece to fall off; The occlusal portion 14 provides the patient's teeth for bite to maintain the patient's mouth open, and allows the tracheal intubation 1 to enter the human oral cavity for corresponding anesthesia, first aid or oxygen supply; the stop 15 is set at The body is outside the oral cavity; the extension 16 is provided for the nurse or physician to hold to place or remove the mouthpiece in the oral cavity of the human body, and the extension 16 can also be used for the nurse or physician to perform corresponding tape sticking Paste and fix.
[0020] The elastic covering member 20 includes a covering body 21, a positioning portion 22 covering the surface of the channel 12 adjacent to the tongue depressing portion 13, and an elastic blocking piece 23 covering the stopper 15 correspondingly, The elastic baffle 23 extends outward from the center, and is correspondingly arranged on the outside of the lips, so as to prevent the mouthpiece from sliding into the human oral cavity. In addition, in order to enhance the effect of fixing, the elastic covering member 20 can also be coated on the inner surface of the channel 12, thereby completely covering the rigid pipe 10, so as to reduce the elastic covering member 20 and the rigid tube. The probability of detachment of the quality pipe 10.
[0021] To further illustrate, the stopper 15 includes a first notch area 151, and the elastic blocking piece 23 has a second notch area 231 corresponding to the first notch area 151 to firmly rely on the tracheal intubation tube 1. The tongue depressing portion 13 extends from the position of the bite portion 14 to a position away from the stopper 15, and has a tapered arc section 131 adjacent to one side of the channel 12 and a pressing portion away from the side of the channel 12 Section 132, through which the pressing section 132 can be used as a means of pressing the tongue to protect the tracheal intubation tube 1 from the interference of the tongue, and the tapered arc section 131 is smoother to avoid compressing the oral mucosa and causing damage to the oral mucosa And there is the problem of infection or festering.
[0022] In this embodiment, the tongue pressing portion 13 further has at least one first through hole 133 perpendicular to the axial direction of the channel 12, and the elastic covering member 20 covers and penetrates the first through hole 133. In addition, please refer to Figure 5 As shown, the stopper 15 has at least one second through hole 152 parallel to the axial direction of the channel 12 for the elastic covering member 20 to cover and penetrate. The elastic covering member 20 penetrates the first through hole 133 and the second through hole 152 to enhance the mutual fixing ability of the rigid tube 10. Therefore, even if the patient bites off the elastic covering member 20 at the occlusal portion 14 due to excessive force, the elastic covering member 20 can still be connected to the first through hole 133 and the second through hole 152. The stable covering is fixed on the hard pipe 10 to avoid the problem of the elastic covering 20 and the hard pipe 10 falling off.
[0023] Please refer to Image 6 As shown, the elastic baffle 23 of the elastic covering member 20 has a plurality of protrusions 232 on a side surface adjacent to the occlusal portion 14. The arrangement of the protrusions 232 can prevent the elastic baffle 23 from being damaged for a long time. Contact with the outside of the patient’s lips, causing pressure sores on the lips. In addition, the elastic baffle 23 can be made of a transparent material, so that the nursing staff can directly observe the color of the patient's lips so as to judge the patient's physical condition.
[0024] Please refer to Figure 4B As shown, in order to further alleviate the influence of the occlusal force of the patient's teeth, the occlusal portion 14 has two alveoli 141 respectively corresponding to the positions of an upper row of teeth and a lower row of teeth of the human oral cavity, and the elastic covering member 20 There are two bite protrusions 24 corresponding to the tooth grooves 141 respectively. In other words, the thickness of the tooth bite protrusion 24 will be thicker than that of other areas of the elastic covering member 20. On the one hand, the patient can have better elasticity when biting through the tooth bite protrusion 24 and provide better elasticity. Good cushioning, and the use of the thicker tooth bite protrusion 24 can reduce the chance of the elastic covering member 20 being bitten by the patient. On the other hand, the tooth bite protrusion 24 and the tooth groove 141 are used to cooperate and fix , The fixing and positioning ability of the elastic covering member 20 and the rigid pipe member 10 can also be further enhanced.
[0025] In summary, the present invention has the following characteristics:
[0026] 1. Utilize the rigid tube in the shape of the tube body to match the design of the tongue depressor to avoid the problem that the mouthpiece is easily pushed out by the patient.
[0027] 2. The arrangement of the covering body and the positioning part can effectively prevent the patient's tongue from contacting the hard tube and causing scratches, causing damage and infection of the tongue and the oral cavity.
[0028] 3. The formation of the first notch area and the second notch area provides a stable positioning space that depends on the tracheal intubation and enters and exits the oral cavity of the human body.
[0029] 4. The first through hole and the second through hole are used to cooperate with the connection of the elastic covering member to strengthen the fixed connection between the elastic covering member and the hard tube, even if the elastic covering member is bitten by the patient If the force is too strong and breaks, the elastic covering member can still be fixedly connected to the hard pipe member.
[0030] 5. Cooperating with the arrangement of the tooth groove and the tooth bite protrusion, on the one hand, it provides a better cushioning force during occlusion and reduces the possibility of the elastic covering member being bitten by the patient. On the other hand, it also provides the hard tube Better fixing and positioning ability with the elastic covering member.
[0031] The present invention has been described in detail above, however, what is described above is only a preferred embodiment of the present invention, and should not limit the scope of implementation of the present invention. That is, all equal changes and modifications made according to the scope of application of the present invention should still fall within the scope of the patent of the present invention.
