Description

Technical Field

[0001] The utility model relates to the field of respiratory equipment, in particular to an oropharyngeal ventilator. Background Art

[0002] The oral cavity is an important part of the human respiratory tract, and tongue root fall is one of the important causes of respiratory obstruction. Adults are prone to narrowing or obstruction of the respiratory tract due to tongue root fall during sleep, which can lead to snoring or even apnea. At the same time, during general anesthesia surgery, the tongue root may fall due to the effect of drugs, increasing the risk of suffocation for patients; comatose patients due to other reasons are also at risk of suffocation due to tongue root fall. Therefore, preventing tongue root fall through medical device intervention is of great significance in life and clinical practice.

[0003] At present, in order to prevent the tongue from falling back and causing snoring, apnea, etc., there are mainly solutions such as mandibular advancement appliances and ventilators; for patients with postoperative drug effects and coma, ventilators and various oropharyngeal airways (tubes) are mainly used for auxiliary treatment. However, the above methods all have certain limitations, such as the high price of ventilators and high requirements for use conditions, the mandibular advancement appliance needs to be customized, the effect of oropharyngeal airways (tubes) is not satisfactory, the comfort is poor, and intubation is required. Utility Model Content

[0004] The utility model aims to solve the above problems and provide an oropharyngeal ventilator, which can conveniently alleviate the symptoms of poor breathing caused by tongue root falling back.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is an oropharyngeal ventilator, which includes a connecting part and a gas channel, one end of the connecting part is connected to the positioning part, and the other end of the connecting part is connected to the tongue depressor; the tongue depressor includes a tongue depressor airbag and a tongue depressor blade; one end of the gas channel is connected to the tongue depressor airbag, and the other end of the gas channel is connected to the inflation device through the trachea. When in use, the tongue depressor is located at the upper part of the tongue root, and pushes the tongue together with the lower jaw to the side of the front teeth, so that the tongue will not fall down and block the respiratory tract.

[0006] Furthermore, flow channels are provided in both the connecting portion and the positioning portion, and the connected flow channels constitute a gas channel. The flow channel in the connecting portion is connected to the tongue depressor airbag, and the flow channel in the positioning portion is connected to the trachea.

[0007] Furthermore, the outer sides of the connecting part and the positioning part are covered with a soft rubber part, the hardness of the soft rubber part is greater than the hardness of the tongue depressing airbag, and the gap between the soft rubber part and the connecting part and the positioning part constitutes an air channel. The soft rubber part on the outer side of the connecting part is connected to the tongue depressing airbag, and the soft rubber part on the outer side of the positioning part is connected to the trachea.

[0008] Furthermore, the gas channel is composed of a gas pipeline.

[0009] Furthermore, the connecting part is U-shaped, and the tongue depressing part is arranged on both sides of the opening end of the connecting part to facilitate the placement of the tongue and can simultaneously generate thrust on the left and right sides of the tongue; a tongue supporting plate is arranged at the lower end of the middle part of the connecting part, and the tip of the tongue is placed at the upper end of the tongue supporting plate to prevent the tip of the tongue from being inserted between the connecting part, the positioning part and the teeth, thereby pushing the connecting part off the teeth; at the same time, the tongue is located at the upper end of the tongue supporting plate, so that the tongue in a natural state will give the bracket a downward force, so that the bracket will not detach from the mandibular teeth.

[0010] Furthermore, the air tube can be detachably connected to improve wearing comfort.

[0011] Furthermore, an observation airbag is arranged on the trachea, so that the pressure condition in the tongue depressor airbag can be judged by naked eye observation, finger pinching, etc.; at the same time, when there is air leakage, it can be replenished or replaced in time.

[0012] Furthermore, the inflation device includes an inflatable airbag and a valve connected to the trachea to facilitate the wearer to inflate the tongue depressor airbag.

[0013] Furthermore, in order to prevent the connecting part etc. from moving in the oral cavity and thus affecting the use effect, the positioning part includes a slot that cooperates with the mandibular teeth, and the slot is clamped on the mandibular teeth to ensure that the connecting part etc. will not shake.

[0014] Furthermore, the positioning portion also includes an upper jaw baffle arranged at the upper end of the slot. When worn, the upper jaw teeth press against the inner side of the upper jaw baffle, thereby ensuring the forward movement of the lower jaw and improving the anti-snoring effect.

[0015] The beneficial effects of the utility model are as follows: the tongue is relatively soft, so the connecting part does not need to be customized, but can be mass-produced in different sizes for customers to choose from, thereby reducing the cost of use. When in use, the tip of the tongue passes under the tongue depressor, and then the connecting part is pushed toward the throat until the tongue depressor moves to the root of the tongue and the mouth can be closed. After the connecting part is placed, the tongue depressor airbag is inflated by the inflation device. Since the upper palate cannot move, as the tongue depressor airbag expands, the tongue depressor will exert a forward thrust on the root of the tongue, preventing the tongue from falling and blocking the respiratory tract. The above-mentioned action does not require intubation, nor does it require a ventilator, etc., thereby conveniently alleviating the symptoms of poor breathing caused by the tongue root falling back.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.

[0024] Example 1: Figure 1-4 As shown, the present embodiment discloses an oropharyngeal ventilator, which includes a connecting portion 1 and a gas channel, wherein one end of the connecting portion 1 is connected to the positioning portion 2, and the other end of the connecting portion 1 is connected to the tongue depressor 3; the connecting portion 1 and the positioning portion 2 as well as the connecting portion 1 and the tongue depressor 3 can be integrally formed, or can be separately formed and then assembled, the connecting portion 1, the positioning portion 2 and the tongue depressor 3 are made of hard materials such as plastic and metal that meet hygienic requirements, and can also be made of rubber with higher hardness; the tongue depressor 3 includes a tongue depressor airbag 4 and a tongue depressor plate 5, the tongue depressor airbag 4 can cover the tongue depressor plate 5, or the tongue depressor airbag 4 is located at the lower end of the tongue depressor plate 5, in the present embodiment, the tongue depressor airbag 4 is arranged at the upper end of the tongue depressor plate 5, and the hardness of the tongue depressor plate 5 is greater than that of the tongue depressor airbag 4, thereby ensuring sufficient thrust on the root of the tongue; one end of the gas channel is connected to the tongue depressor airbag 4, and the other end of the gas channel is connected to the inflation device through the trachea 6.

[0025] In order to improve the wearing comfort, the connecting part 1 includes two arcuate edges, which are connected in a U shape. The U shape formed by them is adapted to the mandibular dental arch, and the air avoidance area in the middle can facilitate the placement of the tongue. At the same time, the middle part of the connecting part, that is, the lower end of the connection of the two arcuate edges is provided with a tongue support plate 12 extending toward the throat side, and the tip of the tongue is placed on the upper end of the tongue support plate 12 to prevent the tip of the tongue from being inserted between the positioning part and the teeth, thereby pushing the connecting part 1 off the teeth. At the same time, the two arcuate edges of the connecting part 1 are connected by the tongue support plate 12 to strengthen the strength of the connecting part 1; the tongue depressing part 3 is arranged on both sides of the open end of the connecting part 1, that is, the end of the arcuate edge and extends toward the inside of the tongue, and at the same time, the connecting part 1 is folded inward on one side of the tongue depressing part 3.

[0026] The positioning portion 2 includes a slot 10 that cooperates with the mandibular teeth. For easy wearing, the slot 10 is preferably matched with the mandibular incisors. Since the sizes and shapes of teeth of different people are different, a buffer layer is provided on the wall of the slot 10. The buffer layer can be made of silicone, sponge, etc., so that when the teeth are inserted into the slot 10, the teeth can contact the buffer layer.

[0027] The positioning portion 2 also includes a maxillary baffle 11 arranged at the upper end of the slot. Flexible materials such as silicone stickers can be pasted on the inner side of the maxillary baffle 11 to improve wearing comfort and adjust the backbite distance. The maxillary baffle 11 in this embodiment is located at the maxillary incisors.

[0028] Specific usage process: put the cleaned connecting part 1, positioning part 2 and tongue depressing part 3 into the oral cavity. When putting them in, the tip of the tongue first passes under the tongue depressing part 3, and then push the connecting part 1 to the throat side until the tongue depressing part 3 moves to the root of the tongue, and then the card slot 10 is clamped on the mandibular teeth. At this time, the connecting part 1 is located under the tongue or between the tongue and the mandibular teeth. In order to improve the wearing comfort, the preferred position of the connecting part 1 is between the tongue and the mandibular teeth, and the tip of the tongue is placed on the upper end of the tongue support plate 12. Figure 4 The dotted line in the middle shows the tongue. Figure 4 The outer side of the middle connecting part 1 is a schematic diagram of the mandibular teeth; after the slot 10 is worn, the outer side of the maxillary incisors presses against the maxillary baffle 11, so that the mandible cannot move back. After the connecting part 1 is placed, the tongue depressor airbag 4 is inflated by the inflation device. Since the hardness of the upper jaw is greater than that of the tongue, as the tongue depressor airbag 4 expands, the tongue depressor airbag 4 presses against the upper palate, thereby pushing the tongue depressor 5 to move toward the tongue side. At this time, the tongue depressor 5 will generate a forward thrust and downward pressure on the root of the tongue, preventing the tongue from blocking the respiratory tract due to falling, thereby improving breathing.

[0029] Embodiment 2, as Figure 5As shown, the other structures and usage processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, flow channels 101 are provided in both the connecting portion 1 and the positioning portion 2, and the connected flow channels 101 constitute a gas channel. The flow channel 101 in the connecting portion 1 is connected to the tongue depressor airbag 4, and the flow channel 101 in the positioning portion 2 is connected to the trachea 6.

[0030] Embodiment 3, as Figure 6 As shown, the other structures and use process of this embodiment are the same as those of embodiment 1, but in this embodiment, the gas channel is composed of a gas pipeline 102, and the gas pipeline 102 is a tube made of a flexible material. In order to prevent the gas pipeline 102 from moving and improve the wearing comfort, the gas pipeline 102 at one end of the tongue depressor airbag 4 in this embodiment is bonded to the outer wall of the connecting part 1, and the gas pipeline 102 at one end of the trachea 6 is bonded to the positioning part 2. The gas pipeline 102 in this embodiment can be integrally formed with the trachea 6.

[0031] Embodiment 4, as Figure 1 As shown, the other structures and usage processes of this embodiment are the same as those of Embodiment 1, but in this embodiment, the outer sides of the connecting part 1 and the positioning part 2 are covered with a soft rubber part. To ensure comfort, the lower end of the tongue depressor 5 may also be provided with a soft rubber connected to the soft rubber part on the connecting part 1. The soft rubber part and the soft rubber are made of rubber, latex, silicone and other materials. The hardness of the soft rubber part and the soft rubber is greater than that of the tongue depressor airbag 4.
