Description

Technical Field

[0001] The utility model belongs to the technical field of oral tooth pads, and specifically relates to a novel tracheal intubation tooth pad capable of preventing oral mucosal damage. Background Art

[0002] During tracheal intubation, in order to prevent the patient from biting the intubation instrument or his own oral tissues due to the bite reflex, a tooth pad can be placed between the teeth to reduce the patient's bite force, thereby reducing the risk of oral injury; during the intubation process, the tooth pad can provide additional support to help stabilize the position of the intubation instrument. This is crucial to ensure that the intubation instrument enters the trachea correctly and avoids accidental displacement or falling off.

[0003] In the existing tracheal intubation operation, the position of the tooth pad is generally placed between the teeth on both sides or on the tongue, and the mouth is opened with the expansion structure to ensure the smooth intubation process. However, during the intubation process, medical staff need to test the position of the intubation tube entering the trachea. Therefore, when testing in the mouth, it is easy to scratch the mucosa on both sides of the mouth, causing secondary damage to the patient. It is impossible to form a shielding protection for the inner oral mucosa between the teeth, thereby reducing its safety of use. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of endotracheal tube tooth pad which can prevent oral mucosal damage and can be filled according to the angle of the patient's oral teeth, so as to protect the oral mucosa inside the teeth and support the teeth.

[0007] The angle conversion assembly includes two circular gears rotatably connected in a hollow plate, the two circular gears are meshed with each other, the circular gear on the rear side is meshed with a half gear, and a rack is meshed on one side of the circular gear on the front side. A screw is threadedly connected to the front side wall of the baffle, and the rear end of the screw extends into the hollow plate and is rotatably connected to the rack.

[0009] Two screw holes are arranged on the bottom surface of the splicing plate, and the inner threads of the screw holes are connected with filling blocks.

[0010] The side wall of the baffle is symmetrically provided with two reserved holes.

[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0024] like Figure 1-Figure 7 As shown, a new type of endotracheal tube tooth pad for preventing oral mucosal damage includes a baffle 1, which is arranged in an arc shape to adapt to the curvature of the mouth. A through hole 2 is opened on the side wall of the baffle 1, and a limit ring 3 is fixedly connected to the rear side wall of the baffle 1. The cross section of the limit ring 3 is L-shaped, and an air cushion 4 is fixedly connected to the side wall. Two hollow plates 5 are symmetrically fixedly connected to the rear side wall of the limit ring 3. The rear side wall of the hollow plate 5 is open, and a half gear 7 is rotatably connected to the hollow plate 5. An angle conversion component is arranged in the inner cavity of the hollow plate 5, and a plurality of splicing plates 6 are arranged on the rear side of the half gear 7. The frontmost splicing plate 6 is fixedly connected to the half gear 7, and a clamping component is arranged between the splicing plates 6. Silicone pads 11 are fixedly connected to the upper and lower side walls of the splicing plate 6 respectively.

[0025] like Figure 3 and Figure 7 As shown, the angle conversion assembly includes two circular gears 8 rotatably connected in the hollow plate 5, the two circular gears 8 are meshed with each other, the rear circular gear 8 is meshed with the half gear 7, a rack 9 is meshed on one side of the front circular gear 8, a screw 10 is threadedly connected to the front side wall of the baffle 1, and the rear end of the screw 10 extends into the hollow plate 5 and is rotatably connected to the rack 9.

[0026] Among them, in order to increase the operating stability of the rack 9, the rack 9 can be connected to the inner wall of the hollow plate 5 in the form of a slider groove to limit the rack 9; in addition, two rectangular grooves are also symmetrically opened on the rear end surface of the hollow plate 5, and the width of the rectangular groove is greater than the thickness of the half gear 7, so that the half gear 7 can drive the splicing plate 6 to change its angle without causing motion interference therewith.

[0027] like Figure 4-Figure 6 As shown, the clamping assembly includes a T-shaped block 12 fixedly connected to the front end surface of the splicing plate 6, a groove 13 is formed on the rear end surface of the splicing plate 6, a T-shaped slot 14 is formed on the bottom surface of the groove 13, and the T-shaped block 12 is adapted to the T-shaped slot 14.

[0028] The design of T-shaped blocks 12 and T-shaped slots 14 has the characteristics of simple structure, quick splicing, good stability, etc., and is also convenient for medical staff to quickly disassemble and disinfect after use; in addition, the length, width, curvature and other parameters of the splicing plate 6 can be limited according to actual needs, and no specific limitations are made in this solution.

[0029] like Figure 4 As shown, two screw holes 15 are provided on the bottom surface of the splicing plate 6 , and a filling block 16 is threadedly connected to the inner surface of the screw hole 15 .

[0030] Specifically, the filling block 16 is mainly made of soft materials such as silicone. When individual users are missing teeth, the filling block 16 can be used to fill the missing position to protect the gums and mucosa, further expanding the protection range and flexibility of use. The length of the splicing plate 6 can be set to one tooth length or two or more lengths, and can be selected and used on-site according to the patient's oral condition.

[0031] like Figure 1 and Figure 2 As shown, two reserved holes 17 are symmetrically formed on the side wall of the baffle 1 .

[0032] Specifically, the main function of the reserved hole 17 is to facilitate the later installation of the elastic band, and the baffle 1 is fixed to the patient's oral position using the elastic band, omitting the traditional method of bonding with tape. The use of the elastic band is only one form of this solution, and methods other than this solution can also be selected according to needs.

[0033] The working principle of the utility model is as follows: when the patient needs to be intubated, firstly, according to the distribution angle of the patient's oral teeth and the depth of the oral cavity, a suitable number of splicing plates 6 are selected, and each splicing plate 6 is connected, and the T-shaped block 12 at one end of the splicing plate 6 is first inserted into the groove 13 on the other side, and then pressed downward so that the T-shaped block 12 is stuck in the T-shaped groove 14, and the silicone pad 11 is in a flush state, and then the splicing plate 6 and the silicone pad 11 are placed in the patient's oral cavity, and the patient's front teeth bite on the air cushion 4 to increase the comfort of the patient's oral cavity, and then the angles of the silicone pads 11 on both sides are adjusted to between the teeth on both sides;

[0034] First, rotate the screw 10 to drive the rack 9 to move, and the rack 9 engages the front circular gear 8. The front circular gear 8 drives the half gear 7 to rotate through the rear circular gear 8. The half gear 7 drives the splicing plate 6 and the silicone pad 11 to change the angle. When the silicone pad 11 is located between the teeth on both sides, it stops rotating, which can not only protect the oral mucosa inside the teeth, but also support the teeth.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
