Description

Technical Field

[0001] The utility model relates to a dental pad, in particular to a medical dental pad with bilateral grooves and a rotatable split type. Background Art

[0002] Orotracheal intubation, as a way to open the respiratory tract, is used to ensure the smoothness of the patient's respiratory tract during rescue and general anesthesia surgery. After the tracheal intubation is successfully inserted, a dental pad is inserted to fix the tracheal intubation and prevent the patient from biting the tube, avoiding deformation, lumen stenosis or closure of the tracheal catheter caused by occlusion, ensuring the safety of the tracheal catheter, and ensuring the smooth breathing of the patient.

[0003] Most of the dental pads currently used in hospitals are made of high-density polyethylene resin and soft polyvinyl chloride materials, and are tied through the holes on the ear wings of the dental pad by a fixing band and then through the patient's face and the back of the neck. The function is to protect the safety of the tracheal intubation and is easy to place in the oral cavity. However, due to the hard texture of the dental pad, its front end and the edges of the two wings are relatively sharp, and it is easy to cause pressure sores in the patient's lips and oral cavity during use. The oral mucosa is easily damaged, blistered (bleeding), ulcerated, etc. due to the compression and friction of the dental pad. In addition, the existing dental pad has a poor fit with the patient's tongue surface, resulting in discomfort for the patient to wear. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned existing technologies, the purpose of the utility model is to provide a rotatable split type medical dental pad with a reasonable structural design. The main body of the dental pad is not easily bitten and damaged by the patient, ensuring the safety and patency of the tracheal intubation, and also reducing or avoiding skin damage such as lip pressure sores and ulcers caused by the compression, friction or sliding friction in the oral cavity of the tracheal intubation patient, and improving the wearing comfort.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A rotatable split type medical dental pad, including a dental pad main body. The section of the dental pad main body for inserting into the oral cavity is the occlusion section. The dental pad main body is made of a hard material and a limiting part is formed on the dental pad main body. There is a tracheal intubation fixing part on the limiting part. It is characterized in that it further includes a soft silicone occlusion part, and the soft silicone occlusion part is wrapped outside the occlusion section of the dental pad main body. The use of the soft silicone occlusion part can avoid the hard dental pad from pressing on parts such as the lips, tongue, palate and gums, thus avoiding the occurrence of pressure sores, damage and other situations.

[0007] Further, the soft silicone bite piece is divided into two sections: one section has an opening for the dental pad body to pass through, and the inner wall of this section fits against the corresponding position of the dental pad body; there is a gap between the inner wall of the other section and the corresponding position of the dental pad body. When there is a gap between the soft silicone bite piece and the hard dental pad body, it can play a good buffering role. Especially when the patient bites the dental pad restlessly, it can effectively relieve the pressure, friction and damage degree of the dental pad on the upper palate, tongue surface, gums, inner walls of both cheeks, etc.

[0008] Further, the bottom surface of the section of the soft silicone bite piece that has a gap with the dental pad body is composed of a downward convex arc surface and an upper inclined surface. The arc surface and the upper inclined surface are smoothly transitioned, and the upper inclined surface is in an upward inclined shape from the end close to the arc surface to the end far from the arc surface. Due to the obstruction of the teeth, the dental pad together with the tracheal intubation is inserted into the oral cavity at a certain angle. The bottom of the conventional dental pad bite part is flat or an outward convex arc surface. When inserted into the oral cavity at an angle, the contact surface between the bottom of the bite part and the tongue surface is relatively small, the fit between the dental pad and the tongue surface is insufficient, and the compression point of the dental pad on the tongue surface is too small, resulting in an increase in discomfort. However, through the setting of the upper inclined surface in this application and in cooperation with the convex arc surface, after the dental pad of this application is inserted into the oral cavity, the upper inclined surface can be in large-area contact with the tongue surface, and the discomfort of the patient is reduced.

[0009] Further, the included angle between the upper inclined surface and the horizontal plane is 25°. This angle meets the requirements of ergonomic design.

[0010] Further, a groove for supporting the tracheal intubation and limiting the tracheal intubation is formed on the side surface of the soft silicone bite piece; a special card slot for the tracheal intubation is opened on the limiting part of the dental pad body, and the groove is coaxial with the special card slot for the tracheal intubation during use. The main functions of the groove and the special card slot for the tracheal intubation are to support the tracheal intubation and limit the tracheal intubation relative to the dental pad body, and then to be fixed under the action of the tracheal intubation fixing member (i.e., the fixing band), which can make the position of the tracheal intubation relatively stable, reduce the occurrence probability of sliding friction caused by the tracheal intubation deviating from the dental pad body, and ensure the safety and comfort of the use of the tracheal intubation.

[0011] Further, two grooves are provided and are axially symmetrically arranged. During use, the dental pad body can be rotated to align the special card slot for the tracheal intubation on the dental pad body with the grooves in different directions (left or right), so as to change the position of the tracheal intubation (or the left or right side of the dental pad body), and avoid always pressing one part.

[0012] Further, a first through hole penetrating through both ends in the length direction is opened on the dental pad body; a second through hole penetrating through its length direction and communicating with the first through hole is opened on the soft silicone bite piece. Through the connected first through hole, second through hole, etc., it is convenient to insert a suction tube to suck out the secretions in the oral cavity and throat.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model is provided with a soft silicone bite piece sleeved outside the hard mouthguard body. By contacting the upper palate, tongue surface, gums and other parts of the patient through the soft silicone bite piece, it can effectively reduce the pressure of the mouthguard on the aforementioned parts, avoid the occurrence of pressure sores, breakage and other situations, and improve the comfort of the patient's oral cavity;

[0015] 2. The present utility model designs the soft silicone bite piece into a flat oval shape (or duckbill shape) with a gap between it and the mouthguard body, which can make it better fit the tongue surface and other parts in the oral cavity without pressing, and improve the wearing comfort;

[0016] 3. The present utility model sets the fixing part of the tracheal intubation on the side of the mouthguard body, and through multiple limit positions such as the tracheal intubation fixing part on the mouthguard body and the groove of the soft silicone bite piece, it can effectively prevent the tracheal intubation from generating sliding friction, slipping and other phenomena, and at the same time vacate the positions of the first through hole in the center of the mouthguard body and the second through hole in the center of the soft silicone bite piece, which is convenient for the suction tube to suck out the secretions in the oral cavity and throat through the first through hole and the second through hole;

[0017] 4. The present utility model is provided with grooves for fixing the tracheal intubation on both sides of the soft silicone bite piece, which is convenient for changing the fixing part of the tracheal intubation from one side to the other when the mouthguard body is rotated 180°, avoiding pressing the same part for a long time;

[0018] 5. The mouthguard of the present utility model is applicable to patients with oral tracheal intubation, especially for patients with tracheal intubation in prone position ventilation, which can reduce the incidence of oral instrumental pressure sores. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings and preferred embodiments in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0025] In this article, terms related to connection relationships are all carried out in a conventional manner.

[0026] As Figures 1-4 As shown, a rotary split-type medical dental pad of the present utility model includes a dental pad body 1, a soft silicone bite piece 2, and a fixing band 3. The dental pad body 1 is made of a hard material, and the top and bottom surfaces of the rear end are designed as inclined surfaces that incline towards the horizontal plane where the central axis is located (this rear end is called the tip). A first through hole 1.1 that penetrates its length direction is opened in the middle of the dental pad body 1. A relatively narrow horizontal plane (called the bite surface) is designed on the outer walls of the top and bottom of the dental pad body 1. The dental pad body 1 is generally in a near-cylindrical shape. The rear end of this dental pad body 1 is slightly pointed, although it is easy to be inserted into the oral cavity, it is easy to cause damage to the lips and oral skin mucosa. The left section of the annular limiting part 1.2 of the dental pad body 1 is the holding section, and the right section is the biting section. The annular limiting part 1.2 is formed at a position slightly to the left of the middle of the dental pad body 1. The annular limiting part 1.2 of the dental pad body 1 plays a limiting role when the dental pad is inserted into the oral cavity. The annular limiting part 1.2 of the dental pad body 1 and its left section are all located outside the oral cavity, and the right section is located inside the oral cavity. A special card slot 1.3 for the tracheal intubation to pass through and support the tracheal intubation is formed on one side of the limiting part 1.2. The opening of the special card slot 1.3 penetrates the outer edge of the limiting part 1.2. In addition, two through holes 1.4 for the two ends of the fixing band 3 to pass through respectively are also opened on the limiting part 1.2.

[0027] The outer periphery of the limiting part 1.2 of the dental pad main body 1 and the holding section are also wrapped with food-grade soft silica gel 4. When wrapping with the food-grade soft silica gel 4, it is necessary to leave a blank at the positions of the two through holes 1.4 for the fixing straps 3 to pass through. A soft silica gel occluding member 2 is sleeved outside the occluding section of the dental pad main body 1. The soft silica gel occluding member 2 is hollow and the hollow cavity penetrates at least one end in the length direction of the soft silica gel occluding member 2 for the occluding section of the dental pad main body 1 to penetrate into. The soft silica gel occluding member 2 wraps the tip of the dental pad main body 1, etc.

[0028] The soft silica gel occluding member 2 is divided into two sections, front and back: one section has an opening for the dental pad main body to penetrate into and the inner wall of this section fits against the corresponding position of the dental pad main body 1 (this section is called the cylindrical part 2.1), and there is a gap 5 between the inner wall of the other section and the corresponding position of the dental pad main body 1 (this section is called the hollow mouth-containing part 2.2). The front section of the soft silica gel occluding member 2 (the section close to the holding section of the dental pad main body) is the cylindrical part 2.1. The cavity of the cylindrical part 2.1 matches the outer contour of the part of the dental pad main body 1 behind the limiting part 1.2 so that the cylindrical part 2.1 of the soft silica gel occluding member 2 tightly wraps around the corresponding part of the dental pad main body 1; the rear section of the soft silica gel occluding member 2 is the duckbill-shaped hollow mouth-containing part 2.2 (the cavity here is elliptical or oblate). There are gaps between the upper inner wall, lower inner wall, left inner wall, and right inner wall of the hollow mouth-containing part 2.2 and the outer wall on the corresponding side of the dental pad main body 1. The existence of these gaps can play a good buffering role and can effectively relieve the pressure, friction, and damage degree of the dental pad on the upper palate, tongue surface, gums, and the inner sides of the two cheeks when the patient is restless and bites the dental pad.

[0029] The bottom surface of the hollow mouth-containing part 2.2 is composed of a downward convex arc surface 2.21 and an upper inclined surface 2.22. The one close to the cylindrical part 2.1 is the arc surface 2.21 and there is a downward-sloping smooth transition surface between the bottom surface of the cylindrical part 2.1 and the arc surface 2.21. And the angle between the downward-sloping smooth transition surface and the bottom surface of the cylindrical part 2.1 is an obtuse angle of 160°. The rear end of the convex arc surface 2.21 extends to the upper inclined surface 2.22. The two ends of the convex arc surface 2.21 form an obtuse angle of 145°. The angle between the upper inclined surface 2.22 and the horizontal plane is 25°. Such a design conforms to the ergonomic design. When the dental pad is tilted and inserted into the oral cavity to make way for the lower teeth, etc., the upper inclined surface 2.22 can be horizontally attached to the tongue surface, thereby increasing the area of the dental pad attached to the tongue surface and reducing the discomfort of the tongue surface.

[0030] The rear end of the hollow mouthpiece 2.2 is designed with an oval-shaped reduced diameter, and this reduced diameter is the second through hole 2.4. Correspondingly, a first through hole 1.1 that penetrates both ends in the length direction is formed on the mouthguard main body 1. The first through hole 1.1 is connected to the cavity of the soft silicone occluding member 2 and the second through hole 2.4 to facilitate the suction tube to pass through and suck out the secretions in the oral cavity and throat from the oral cavity. Grooves 2.3 for supporting the tracheal intubation and limiting the tracheal intubation are formed on one or both sides (preferably both sides and arranged axially symmetrically) of the hollow mouthpiece 2.2. During use, by rotating the mouthguard main body 1, the special card slot 1.3 for the tracheal intubation is coaxially arranged with one of the grooves 2.3, and then the tracheal intubation is inserted into the special card slot 1.3 and the corresponding groove 2.3, and then fixed by the fixing band 3, which can prevent the tracheal intubation from deviating from the mouthguard main body and generating sliding friction, etc.

[0031] The soft silicone occluding member 2 is made of food-grade silicone, with a soft texture, no peculiar smell, good fit with the oral tongue surface, etc., reducing the pressure on the patient's gums, lips, tongue surface, etc., and not easily forming pressure sores (especially when the patient is restless, with a large biting force and a strong friction force, it is not easily formed pressure sores), which can reduce the discomfort of the patient and reduce the nursing difficulty. The soft silicone occluding member 2 can be removed from the mouthguard main body 1 for cleaning and then disinfected for reuse (when the soft silicone occluding member 2 cannot tightly wrap the mouthguard main body, the soft silicone mouthpiece 2 can be discarded), preventing it from falling off; by rotating the mouthguard main body 1 by 180°, the special card slot 1.3 on it is rotated to the other side to correspond to another groove 2.3 on the soft silicone occluding member 2, and then the tracheal intubation is fixed, which is convenient for better replacement of the position of the tracheal intubation in the oral cavity, improving the versatility of the mouthguard, and avoiding long-term compression of the same part.

[0032] The tracheal intubation fixing member for fixing the mouthguard is the fixing band 3. The fixing band 3 is a pure cotton widened inch band, and both ends are inclined edges with an inclination angle of 15°, which is easy to pass through the two through holes 1.4 on the limiting part 1.2. During use, the tracheal intubation passes through the special card slot 1.3 and one of the grooves 2.3 in sequence from front to back for double limiting, and then the fixing band 3 is used to tie and fix the tracheal intubation to prevent the tracheal intubation from shifting. After the tracheal intubation is firmly fixed, according to the patient's neck circumference, the tracheal intubation and the mouthguard main body are fixed by the double knot method, and the fixing band is tied around the neck and fixed.

[0033] During use, first insert the tracheal intubation. One nurse fixes the tracheal intubation by hand, while the other nurse checks and cleans the oral cavity and cheek area. The tracheal intubation is located in the middle of the oral cavity. Then insert the dental pad (between the upper and lower molars), and then snap the tracheal intubation into the special card slot and groove to form double limit, and use the fixing band to tie and fix the tracheal intubation, which can effectively prevent the tracheal intubation from shifting. After the catheter and the dental pad are inserted, they can be moved left and right together, or the main body of the dental pad can be rotated to change the position of the tracheal intubation, so as to avoid the occurrence of pressure sores caused by long-term compression of the same part such as the lips and tongue.

[0034] The dental pad of the present utility model solves the problems of the existing dental pads, improves the problems of the existing dental pads with hard and sharp edges, poor fit with the gums and tongue surface, insufficient softness despite sufficient hardness, lack of safety performance and comfort, separation of the oral end of the dental pad from the tracheal intubation catheter, easy to cause sliding friction, causing pain and discomfort to the patient, insufficient firmness of the inch band fixation, and inability to guarantee the safety performance of the tracheal intubation catheter, etc. At the same time, it reduces the incidence of instrumental pressure sores caused by the hardness of the dental pad. The dental pad of the present utility model combines soft texture with hardness, has high safety performance and high comfort, double limits the tracheal intubation catheter, and is fixed again with a fixing band, overcoming the problems existing in the existing dental pads, and maximizing the safety and comfort of patients in the intensive care unit.
