Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical instruments, and in particular relates to a teeth pad for tracheal intubation. Background Art
[0002] In clinical practice, in order to keep the airway of critically ill patients open, a tracheal tube needs to be inserted through the mouth to keep their breathing unobstructed. In order to prevent the patient from biting the tracheal tube, a medical tooth pad is used to prop open the teeth to support and keep the tracheal tube unobstructed. In order to prevent the tube from slipping off, the tooth pad needs to be fixed with both a lace and adhesive tape.
[0003] The dental pads currently used in clinical practice for endotracheal tubes are usually composed of a hard tube and a tooth baffle around the hard tube. Because the outer surface is too hard, patients will feel uncomfortable when biting on it with their teeth, especially patients who are in a state of confusion and patients who are difficult to communicate. They will use their tongues to push out the dental pads after feeling uncomfortable, which will lead to the risk of the endotracheal tube being bitten by the patient and unable to ventilate. In the process of pushing out, the rear end of the dental pad will cause medical device-related pressure damage to the patient's upper jaw. In addition, the original design of the lower baffle of the dental pad will compress the lower lip, causing the problem of medical device-related pressure damage. In addition, the original dental pads need to be fixed with both laces and tape, and tearing off the fixing tape can easily cause damage to the facial skin. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a tooth pad for endotracheal intubation, so as to solve the problems of medical device-related pressure damage caused by the original hard tooth pad causing patient bite discomfort, the pressure of the tooth pad body on the upper palate of the oral cavity and the pressure of the lower baffle of the tooth pad on the lower lip, and the problem that the facial skin is easily damaged by tearing the fixing tape because the original tooth pad needs to be double fixed with a lace and a tape.
[0005] In order to solve the above technical problems, an embodiment of the utility model provides a mouthpiece for endotracheal intubation, comprising a mouthpiece body, a through hole is opened in the mouthpiece body along the length direction, the center line direction of the through hole is parallel to the length direction of the mouthpiece body, a tooth baffle is arranged on the mouthpiece body, the tooth baffle is arranged at the front end of the mouthpiece body, a tongue depressing portion extending inward is arranged at the rear end of the mouthpiece body, and a bite portion is arranged at the rear side of the tooth baffle;
[0006] The tooth baffle includes an upper tooth baffle and a lower tooth baffle, and are respectively arranged at the top and bottom of the front end of the tooth pad body. The length of the upper tooth baffle is smaller than that of the lower tooth baffle. When the lower tooth baffle is fitted with the lips, the contact area of the lips is increased to prevent medical device-related pressure injuries.
[0007] Among them, the upper tooth baffle is provided with a first through hole and a second through hole on both sides, and the lower tooth baffle is provided with a third through hole and a fourth through hole on both sides. The first through hole, the second through hole, the third through hole and the fourth through hole are distributed in a rectangular shape along the center point of the through hole. A first elastic rope is connected through the first through hole and the third through hole, and a second elastic rope is connected through the second through hole and the fourth through hole.
[0008] Wherein, the two ends of the first elastic rope are respectively fixedly connected with the first connecting block and the second connecting block, the two ends of the second elastic rope are respectively fixedly connected with the third connecting block and the fourth connecting block, the first connecting block is detachably connected to the second connecting block, and the third connecting block is detachably connected to the fourth connecting block.
[0009] The first connection block, the second connection block, the third connection block and the fourth connection block are all made of rubber material and are specifically arc-shaped; the first connection block and the second connection block, and the third connection block and the fourth connection block are specifically connected by Velcro.
[0010] Among them, the length of the upper tooth baffle is 3~5mm, and the length of the lower tooth baffle is 9~15mm.
[0011] Wherein, the lower tooth baffle is inclined toward the front end of the tooth pad body, and the inclination angle is 10°~15°.
[0012] Wherein, the tongue pressing portion is an inclined surface structure arranged to be inclined from top to bottom.
[0013] The width of the tongue depressor is greater than the width of the dental pad body, so that the tongue depressor can restrict the patient's tongue from pushing out the dental pad body with a larger area.
[0014] The edges of the tooth baffle and the tongue depressor are passivated and have an arc, so that it is not easy to cause damage to the patient's upper jaw, tongue and lips during long-term use.
[0015] Wherein, the surface of the bite portion is made of an elastic material layer, and the elastic material layer can be made of TPE material.
[0016] The beneficial effects of the above technical solution of the utility model are as follows:
[0017] (1) The utility model restricts the patient by means of the tooth baffle, so that the patient's teeth bite on the bite part, thereby preventing the patient from feeling uncomfortable and pushing out the bite pad body and biting the endotracheal tube. Since the surface of the bite part adopts an elastic material layer, the patient will not feel uncomfortable when biting. Moreover, since the lower baffle is lengthened and thickened and is designed to be inclined at an angle of 10 to 15 degrees, the lower baffle can be better fitted to the patient's lips, avoiding the bottom of the lower baffle being perpendicular to the patient's lips and causing unnecessary medical device-related pressure damage. At the same time, the tongue depressor on the bite pad body is used to open the patient's mouth, so that the tongue depressor presses against the patient's tongue to restrict the patient's tongue and expose the patient's pharynx, thereby restricting the patient from using the tongue to push out the bite pad body;
[0018] (2) The elastic ropes arranged on both sides of the dental pad body can prevent the tongue depressor from excessively extending into the patient's pharynx. The elastic ropes fix the dental pad body on the patient's face, replacing the traditional fixation with fixing tapes, thereby reducing damage to the skin and mucous membranes, thereby preventing patients with thin skin and patients with facial edema from tearing off the fixing tapes and causing damage to the skin and mucous membranes. The detachable connection between the connecting blocks also facilitates the use of the dental pad body. In addition, since the part of the connecting block at the end of the elastic rope that hangs on the patient's ear is made of rubber material, the dental pad body will not cause damage to the patient's ears when used for a long time.

[0025] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0026] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a mouth guard for endotracheal intubation, comprising a mouth guard body 1, a through hole 2 is opened in the mouth guard body 1 along the length direction, the center line direction of the through hole 2 is parallel to the length direction of the mouth guard body 1, the mouth guard body 1 is in the shape of an elongated strip, and PC material is used as the material inside the mouth guard body 1, a tooth baffle is provided on the mouth guard body 1, and the tooth baffle is provided at the front end of the mouth guard body 1, and a tongue depressing portion 6 extending inward is provided at the rear end of the mouth guard body 1. In this embodiment, both sides of the tongue depressing portion are widened, and the width thereof is twice the width of the mouth guard body, and a bite portion 5 is also provided on the tooth baffle, and the bite portion 5 is provided on the rear side of the tooth baffle, and an elastic material layer is used. In this embodiment, the elastic material layer is made of TPE material;
[0027] The tooth baffle includes an upper tooth baffle 3 and a lower tooth baffle 4, which are respectively arranged at the top and bottom of the front end of the tooth pad body 1, and the length of the upper tooth baffle 3 is less than the length of the lower tooth baffle 4. The lower tooth baffle is arranged to be inclined 10° to 15° toward the front end of the tooth pad body to prevent the lower tooth baffle from being vertically pressed against the patient's lower lip. When the patient wants to push out the tooth pad, the tongue depressor is widened to prevent the tooth pad body from shifting and being spit out, and it does not play the role of supporting the tracheal intubation. In the process of tongue pushing out, it also avoids injury to the upper palate to a certain extent.
[0028] The upper tooth baffle plate is provided with a first through hole and a second through hole on both sides, and the lower tooth baffle plate is provided with a third through hole and a fourth through hole on both sides. The first through hole, the second through hole, the third through hole and the fourth through hole are arranged in a rectangular distribution along the center point of the through hole. The first elastic rope is connected through the first through hole and the third through hole, and the second elastic rope is connected through the second through hole and the fourth through hole. The first elastic rope 12 is fixedly connected to the first connecting block 14 and the second connecting block 15 at both ends, and the third connecting block 16 and the fourth connecting block 17 at both ends. The first connecting block 14 is detachably connected to the second connecting block 15, and the third connecting block 16 is detachably connected to the fourth connecting block 17.
[0029] In this embodiment, the first connection block 13, the second connection block 14, the third connection block 15 and the fourth connection block 16 are all made of rubber material and are specifically arc-shaped; the first connection block 13 and the second connection block 14, the third connection block 15 and the fourth connection block 16 are connected by Velcro. The first connection block 13 and the second connection block 14, the third connection block 15 and the fourth connection block 16 are all detachably connected. When the patient uses the dental pad, the dental pad body can be fixed first, and then the connection blocks are connected and fixed to the patient's ears in pairs. Because the rubber material is used and the shape is arc-shaped, the ear pain caused by the patient wearing the dental pad for a long time is greatly alleviated. In addition, the setting of the first elastic rope and the second elastic rope replaces the traditional fixing tape, which reduces the damage to the skin and mucous membrane, so as to prevent the patients with thin skin and patients with facial skin edema from tearing off the fixing tape and causing damage to the skin and mucous membrane.
[0030] The tongue depressor 6 is a slope structure inclined from top to bottom, and the width of the tongue depressor 6 is greater than the width of the dental pad body, so that the tongue depressor can restrict the patient's tongue from pushing out the dental pad body with a larger area.
[0031] The edges of the upper tooth baffle plate 3, the lower tooth baffle plate 4 and the tongue depressor 6 are all passivated and have an arc, so that it is not easy to cause damage to the patient's upper jaw, tongue and lips during long-term use.
[0032] In this embodiment, the length from the front end of the bite pad body to the baffle is 18 mm, the length from the upper tooth baffle to the rear end of the bite pad body is 30 mm, the length from the lower tooth baffle to the tongue depressor is 50 mm, the width of the bite pad body is 13 mm, the length of the upper tooth baffle is 5 mm, the thickness is 2 mm, the length of the lower tooth baffle is 15 mm, the thickness is 2 mm, and the width of the tongue depressor is 26 mm. During use, the length and width of the bite pad body adapt to the human mouth, thereby facilitating the fixation of the tracheal tube.
[0033] The working principle of the utility model is:
[0034] The tongue depressor on the dental pad body is used to open the patient's oral cavity, so that the tongue depressor is pressed against the patient's tongue to restrict the patient's tongue and expose the patient's pharynx, and the patient is also restricted from using the tongue to push out the dental pad body. At the same time, the patient's teeth are restricted by the tooth baffle, so that the patient's lips and teeth are engaged on the engagement part. Since the surface of the engagement part adopts an elastic material layer, the patient will not feel discomfort when engaging. Moreover, since the lower tooth baffle is lengthened and the inclined angle is increased, the lower tooth baffle can be effectively prevented from being vertically pressed on the patient's lower lip. At the same time, the passivation treatment at the edge of the dental pad body also reduces unnecessary damage. After the dental pad body is placed, the first connecting block and the second connecting block are connected to each other, and the third connecting block and the fourth connecting block are connected to each other, and the connecting block set at the end of the elastic rope is hung behind the patient's ear and is tightly attached through the arc portion. Since the part of the connecting block set at the end of the elastic rope hanging on the patient's ear is made of rubber material, the dental pad body will not cause damage to the patient's ear when used for a long time.
[0035] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
