Description

Technical Field

[0001] The utility model relates to the technical field of anesthesia airway management, in particular to a tooth pad for supplying oxygen during non-muscle relaxation general anesthesia. Background Art

[0002] The dental pad is mainly suitable for patients who undergo endotracheal intubation through the mouth in the fields of anesthesiology, emergency and critical patient medicine. After the endotracheal tube is inserted, the dental pad is placed between the two rows of teeth of the patient to prevent the patient's teeth from biting the endotracheal tube or damaging the lips and teeth. Especially for patients such as OSAS, oxygen ventilation can be given after extubation to ensure airway safety.

[0003] With the continuous updating of surgical technology, weak muscle relaxation electrophysiological monitoring (some monitoring requires electrical stimulation of the masseter muscle) and intubation general anesthesia technology with spontaneous breathing in the chest and lung department are increasingly used in clinical practice. Irreversible bite injuries to the mouth, tongue, lips and teeth have been reported many times, and expensive endoscopic instruments are often bitten. When patients under general anesthesia are in the prone position for a long time, it is also easy to cause damage to the lips, teeth, mouth, tongue and gums. For this reason, we propose a tooth pad that can provide oxygen for general anesthesia without muscle relaxation. Utility Model Content

[0004] The utility model aims to provide a non-muscle relaxant general anesthesia oxygen supplying tooth pad to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-muscle relaxant general anesthesia oxygen-supplying tooth pad, including a tooth pad, the tooth pad is arranged in two groups and is symmetrically distributed, a cotton yarn ball is placed on the inner rear surface of the tooth pad, an inflation tube and an oxygen supply tube are fixedly connected to the inner surface of the tooth pad, one end of the inflation tube is inserted into the interior of the cotton yarn ball, a threaded air bag tube is fixedly connected to the interior of the cotton yarn ball, the threaded air bag tube is sleeved on the surface of the inflation tube, the threaded air bag tube and the inflation tube are connected, a tongue depressor is also inserted into the interior of the cotton yarn ball, the tongue depressor is located below the threaded air bag tube, one end of the oxygen supply tube is inserted into the interior of the cotton yarn ball and passes through the cotton yarn ball, and the oxygen supply tube is connected to the front end of the threaded air bag tube.

[0006] Preferably, tooth sockets are provided on both upper and lower surfaces of the tooth pad.

[0007] Preferably, a positioning band is fixedly connected to the outer rear end surface of the tooth pad, and the positioning bands are arranged in two groups and are symmetrically distributed in a "T" shape, and the ends of the positioning bands connected to the surface of the tooth pad are both movable ends.

[0008] Preferably, the outer surface of the tooth pad is provided with a placement hole, and the placement hole is arranged in a rectangular shape.

[0009] Preferably, an opening is provided inside the dental pad, and an oil-emery cloth is fixedly connected to the surface of the cotton yarn ball, and one end of the oil-emery cloth passes through the opening on the surface of the dental pad.

[0010] Preferably, a Murphy hole is provided on the side of the oxygen supply tube.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This solution uses the structure of the dental pad. When two dental pads are placed in the patient's mouth along the patient's molars, the patient's incisor part will be raised to form a channel, which is convenient for medical staff to perform tracheal extubation. It can also prevent the patient from biting the fiberoptic bronchoscope unconsciously during Ebus (bronchoscope ultrasound examination) and prevent the tracheal tube from being bitten and the endoscopic instrument from being bitten. At the same time, it can effectively buffer the strong bite force of electrical stimulation of patients in prone position or electrophysiological monitoring;

[0013] 2. This solution adopts the structure of cotton yarn ball and oil sand cloth. When the dental pad is inserted into the patient's mouth and bitten by the patient, the cotton yarn ball can absorb the secretions in the patient's mouth to prevent the secretions from overflowing or choking the patient after the tube is removed. Due to the fixed setting of the oil sand cloth, the cotton yarn ball can be prevented from falling into the patient's mouth, and it can also play a role of partition between the patient's teeth and lips, and it is convenient to remove the dental pad later;

[0014] 3. This solution uses the structural arrangement of the threaded airbag tube, the inflation tube, the tongue depressor, and the oxygen supply tube so that after the dental pad is placed in the patient's mouth, oxygen is supplied to the patient's mouth through the outer end of the oxygen supply tube and the Murphy hole on its side to ensure smooth breathing of the patient. While the oxygen supply tube supplies oxygen to the inside of the patient's mouth, the inflation tube inflates air into the threaded airbag tube, further expanding the inflated volume of the threaded airbag tube. During the expansion process, the threaded airbag tube pushes the oxygen supply tube to continue to extend deep into the patient's mouth, ensuring that oxygen is sprayed near the glottis. If there is a tongue root suffix, the threaded airbag tube can be manually inflated to lift and press the tongue root proximally to open the airway. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example

[0019] See also Figure 1-2 , the utility model provides a technical solution:

[0020] Non-muscle relaxant general anesthesia can provide oxygen dental pads. The dental pads 1 are set in two groups and are used in a symmetrical distribution, which effectively prevents the closure of the teeth in the patient's mouth. The upper and lower surfaces of the dental pad 1 are provided with tooth sockets 2. The tooth sockets 2 are used to place the teeth when the patient bites the dental pad 1. The dental pad 1 is made of silicone material as a whole, which can effectively prevent the patient from biting too hard and damaging the teeth and gums. The silicone material has a certain curvature plasticity and adopts a split design, which is suitable for patients with different maxillofacial and oral sizes.

[0021] A cotton ball 4 is placed at the rear end of the inner surface of the dental pad 1. When the dental pad 1 is inserted into the patient's mouth and bitten by the patient, the cotton ball 4 can absorb the secretions in the patient's mouth to prevent the secretions from overflowing or choking the patient. At the same time, an opening is provided inside the dental pad 1, and an oil sand cloth 8 is fixedly connected to the surface of the cotton ball 4. The other end of the oil sand cloth 8 passes through the opening on the surface of the dental pad 1. Due to the fixed setting of the oil sand cloth 8, the cotton ball 4 can be prevented from falling into the patient's mouth, and it can also play a role of partition and protection between the patient's teeth and lips, and it is convenient to remove the dental pad 1 later.

[0022] The outer rear end surface of the dental pad 1 is fixedly connected with a positioning band 3, which is arranged in two groups and symmetrically distributed in a "T" shape with the dental pad body. And one end of the two groups of positioning bands 3 connected to the surface of the dental pad 1 is a movable end, so that the movable end of the positioning band 3 can be flipped up and down on the outer surface of the dental pad 1 to fit the patient's gums, which can quickly guide the dental pad 1 to align and limit the displacement of the dental pad 1 during surgery;

[0023] When the two tooth pads 1 are placed in the patient's mouth along the patient's molars, the patient's incisor part will be raised to form a channel, which is convenient for medical personnel to perform tracheal extubation and can prevent the patient from biting the fiberoptic bronchoscope unconsciously during Ebus bronchoscopic ultrasound examination.

[0024] The inner surface of the mouthpiece 1 is fixedly connected with an oxygen supply tube 10, one end of which is inserted into and penetrates the cotton ball 4, and a Murphy hole is provided on the side of the oxygen supply tube 10. When the mouthpiece 1 is placed in the patient's mouth, due to the air permeability of the cotton ball 4, oxygen is supplied to the patient's mouth through the front end of the oxygen supply tube 10 and the Murphy hole on the side, thereby ensuring the patient's breathing smoothness.

[0025] The inner surface of the dental pad 1 is also fixedly connected with an air-filling tube 6, one end of which penetrates into the interior of the cotton yarn ball 4, and a threaded air-bag tube 5 is fixedly connected to the interior of the cotton yarn ball 4, which is sleeved on the surface of the air-filling tube 6, and the threaded air-bag tube 5 and the air-filling tube 6 are connected. A tongue depressor 7 is also inserted into the interior of the cotton yarn ball 4, and the tongue depressor 7 is located below the threaded air-bag tube 5. The threaded air-bag tube 5 can be inflated through the air-filling tube 6, which further causes the inflated volume of the threaded air-bag tube 5 to collide, and the threaded air-bag tube 5 will continue to extend deep into the patient's oral cavity during the expansion process, and the tongue depressor 7 is pressed downward during the extension process. Further, the threaded air-bag tube 5 is inflated and pushes up the hard palate, and the tongue depressor 7 is forced to press down the root of the tongue, thereby opening the patient's pharyngeal cavity and nasal cavity. The front end of the oxygen supply tube 10 is connected to the front end of the threaded airbag tube 5, so that during the inflation process, the threaded airbag tube 5 will extend forward, further pushing the oxygen supply tube 10 to continue to extend deep into the patient's mouth, ensuring that oxygen is sprayed near the glottis; if there is a tongue root suffix, the threaded airbag tube 5 can be manually inflated to press the tongue root proximally to open the airway.

[0026] The outer surface of the dental pad 1 is provided with a placement socket 9 on one side of the oil sand cloth 8, through which the dental pad 1 can be conveniently inserted into the patient's oral cavity by a handle. The placement socket 9 is set in a rectangular shape to prevent the dental pad 1 from rotating when it is placed.

[0027] The two dental pad bodies 1 are made entirely of silicone material, which has a certain curvature plasticity and adopts a split design, which is suitable for patients with different maxillofacial and oral cavity sizes.
