Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel anesthesia tooth pad. Background Art

[0002] Anesthesia bite pads are often used for patients with general anesthesia and endotracheal intubation to prevent the patient's teeth from biting the endotracheal tube flat. Traditional bite pads are generally cylindrical or conical, with two side wings on one end. After the patient is anesthetized and intubated, the bite pad is placed between the upper and lower teeth, with the side wings of the bite pad on the outside of the teeth to prevent the bite pad from falling completely into the mouth. Then, the bite pad and the endotracheal tube are wrapped together with tape, and the end of the tape is attached to the patient's facial skin to fix the endotracheal tube and prevent the endotracheal tube from being bitten flat by the patient. However, for patients in the prone or lateral position, it is very important to prevent the tube from shifting and falling out. The currently commonly used tape-type fixation method has the following shortcomings:

[0003] 1. The tracheal tube cannot be fixed and installed, which can easily cause damage to the patient's trachea. In addition, for patients in the prone position, oral secretions cannot be discharged from the mouth in time and flow into the trachea. Anesthetized patients cannot cough out in time, which can easily cause harm.

[0004] 2. Although the dental pad can limit the tongue when in use, it is usually of a certain thickness. When the part extending into the oral cavity is long, it is easy to cause pressure on the tongue and cause discomfort. Utility Model Content

[0005] The utility model aims to solve the problems that the endotracheal tube cannot be fixedly installed, the secretions produced in the oral cavity cannot be discharged from the oral cavity in time, and the long dental pad easily causes discomfort to the tongue. Therefore, a new type of anesthesia dental pad is provided to solve the above problems.

[0006] In view of the above-mentioned deficiencies in the prior art, the utility model provides a new type of anesthesia bite pad, including a bite pad body, a limit baffle plate is sleeved on the outer side of the bite pad body, a protective soft pad 1 is provided on the upper side of the bite pad body, a protective soft pad 2 is provided on the lower side of the bite pad body, and a groove is provided at the edge of the outer wall of the lower side of the bite pad body;

[0007] The inner side of the bite block body is a hollow structure, a fixed conduit is installed through the middle part of the inner side of the bite block body, and rotating conduits are rotatably installed on the inner side of the bite block body and on both sides of the fixed conduit.

[0008] As an improvement: a limit strip is installed at the front edge of the groove, and the second protective cushion is located between the limit strip and the limit baffle.

[0009] As an improvement: a tracheal cannula is passed through the interior of the fixed catheter, and a connecting tube 1 is connected to the front end of the tracheal cannula.

[0010] As an improvement, a rotating shaft is provided between the upper and lower side walls of the rotating conduit and the inner wall of the tooth pad body for rotation connection.

[0011] As an improvement: a saliva suction tube is passed through the interior of the rotating catheter, and a connecting tube 2 is connected to the front end of the saliva suction tube.

[0012] As an improvement: a U-shaped groove is provided in the middle of the upper side of the limit baffle.

[0013] As an improvement: the protective cushion 1 and the protective cushion 2 are both made of antibacterial silicone material.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The dental pad body is set to a hollow structure, and a fixed catheter and a rotating catheter are set on the dental pad body, which are used to install the tracheal tube and the saliva straw respectively. The tracheal tube is fixedly installed by the fixed catheter to prevent the shaking of the tracheal tube from causing damage to the patient's trachea. The saliva straw is rotatably installed by the rotating catheter, and the position of the saliva straw in the oral cavity can be adjusted to facilitate the suction of secretions inside the oral cavity and prevent the secretions from flowing into the trachea;

[0016] 2. By setting a groove on the lower side of the dental pad body, the patient's tongue is placed inside the groove, which has a good limit on the tongue and does not cause pressure on the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 4 As shown, a new type of anesthesia tooth pad comprises a tooth pad body 1, the outer side of the tooth pad body 1 is covered with a limiting baffle 2, the upper side of the tooth pad body 1 is provided with a protective pad 3, and the lower side of the tooth pad body 1 is provided with a protective pad 2, both of which are made of antibacterial silicone, a groove 5 is provided at the edge of the outer wall of the lower side of the tooth pad body 1, a limiting strip 14 is installed at the front edge of the groove 5, and the protective pad 2 4 is located between the limiting strip 14 and the limiting baffle 2. When the anesthesia tooth pad is used, the rear end of the tooth pad body 1 is placed into the patient's oral cavity, and the patient's teeth are respectively bitten on the outside of the protective pad 1 3 and the protective pad 2 4, and the lower teeth are limited by the limiting strip 14 to prevent the lower teeth from biting into the inner side of the groove 5. The patient's tongue is placed on the inner side of the groove 5 without causing pressure on the tongue.

[0025] The inner side of the bite block body 1 is a hollow structure, and a fixed catheter 6 is installed in the middle of the inner side of the bite block body 1, and an endotracheal tube 7 is passed through the fixed catheter 6. The front end of the endotracheal tube 7 is connected with a connecting tube 8. The endotracheal tube 7 is inserted into the fixed catheter 6 and connected to an external device through the connecting tube 8. There is friction between the inner wall of the fixed catheter 6 and the outer side of the endotracheal tube 7, so that the endotracheal tube 7 will not slide freely inside the fixed catheter 6, and the position of the fixed catheter 6 is fixed, so that the endotracheal tube 7 will not shake, thereby avoiding damage to the trachea.

[0026] A rotating catheter 9 is rotatably installed on the inner side of the tooth pad body 1 and on both sides of the fixed catheter 6. A rotating shaft 10 is rotatably connected between the upper and lower side walls of the rotating catheter 9 and the inner wall of the tooth pad body 1. A saliva suction tube 11 passes through the rotating catheter 9. A connecting tube 2 12 is connected to the front end of the saliva suction tube 11. The saliva suction tube 11 is inserted into the inner side of the rotating catheter 9, so that the saliva suction tube 11 is placed inside the patient's mouth, and is connected to an external suction device through the connecting tube 2 12 for use. The rotating catheter 9 is rotatably connected to the inner wall of the tooth pad body 1 through the rotating shaft 10, so that the saliva suction tube 11 can swing, which is convenient for sucking out secretions at various positions inside the patient's mouth.

[0027] A U-shaped groove 13 is provided in the middle of the upper side of the limiting baffle 2 so that the limiting baffle 2 will not block the lower side of the patient's nasal cavity and will not affect the insertion of the oxygen tube into the nasal cavity.

[0028] The above description is only a preferred embodiment of the present utility model patent and is not intended to limit the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the protection scope of the present utility model patent.
