Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an oropharyngeal ventilation device. Background Art

[0002] Oropharyngeal ventilation is an emergency medical treatment method suitable for patients who are unconscious and unable to keep their airways open. This method can keep the airways open and prevent airway obstruction caused by various reasons. Currently, when oropharyngeal ventilation is used on patients, the patient's head is first tilted back, and a suitable oropharyngeal airway is selected according to the patient's age and body shape. The curved part of the oropharyngeal airway is sent into the mouth along the tongue surface to expand the upper and lower jaws and open the airway. Finally, the oropharyngeal airway is fixed with tape to prevent it from falling off. Since oropharyngeal airways vary in size and variety, it takes a certain amount of time to select the right size of oropharyngeal airway. Sometimes, two or three different oropharyngeal airways must be tried before a suitable one can be found, which increases the time for oropharyngeal ventilation treatment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an oropharyngeal ventilation device, which can quickly adjust the expansion angle and is convenient for different patients to use.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] An oropharyngeal ventilation device comprises an upper support plate, a lower support plate, a rotating shaft and an angle positioning assembly; two first rotating handles are arranged at one end of the upper support plate, and the two first rotating handles are arranged at intervals on both sides of the upper support plate, the upper support plate and the first rotating handle are arranged in an L-shape, and a through first axial hole is arranged on the first rotating handle; the lower support plate is located between the two first rotating handles, and a second rotating handle is arranged at one end of the lower support plate, the lower support plate and the second rotating handle are arranged in an L-shape, and a second axial hole is arranged at the lower end of the lower support plate and close to the second rotating handle; the first axial hole and the second axial hole coincide with each other, and the rotating shaft passes through and connects the first axial hole and the second axial hole; the angle positioning assembly is arranged at the lower ends of the first rotating handle and the second rotating handle, and is used to limit the minimum angle between the upper support plate and the lower support plate.

[0006] Furthermore, the angle positioning assembly includes a baffle and an adjusting bolt. The baffle is fixedly connected between the two first rotating handles. The second rotating handle is provided with a screw hole opposite to the baffle. The adjusting bolt is connected to the screw hole, and one end thereof rests on the baffle.

[0007] Furthermore, the upper support plate and the lower support plate are spaced apart to provide an observation and operation space between them.

[0008] Furthermore, an upper tooth groove with an opening facing upward is provided on the upper support plate, and the upper tooth groove is located at an end opposite to the first rotating handle. A lower tooth groove with an opening facing downward is provided on the lower support plate, and the lower tooth groove is located at an end opposite to the second rotating handle.

[0009] Furthermore, a tongue-pressing portion is provided on one end of the lower alveolar plate and extends forward, and the tongue-pressing portion is used to press on the upper end of the tongue.

[0010] Furthermore, the upper support plate and the lower support plate are made of transparent material.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. After the first axial hole and the second axial hole are passed through and connected by the rotating shaft, the upper support plate and the lower support plate can rotate relative to each other to support the patient's upper jaw and lower jaw, thereby achieving the purpose of expanding and opening the airway. Since the angles of the upper support plate and the lower support plate can be rotated and adjusted, it is not necessary to select the appropriate size according to the patient's age and body shape when using it, as with an oropharyngeal ventilation tube, which helps save operation time.

[0013] 2. By providing an angle positioning assembly at the lower end of the first rotating handle and the second rotating handle to limit the minimum opening angle, it is helpful to avoid the upper support plate and the lower support plate rotating in the opposite direction and causing the patient's mouth to close.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figure 1 to Figure 3As shown, the oropharyngeal ventilation device of this embodiment includes an upper support plate 1, a lower support plate 3, a rotating shaft 5 and an angle positioning assembly 9. Among them, two first rotating handles 2 are arranged at one end of the upper support plate 1, and the two first rotating handles 2 are arranged at intervals on both sides of the upper support plate 1. The upper support plate 1 and the first rotating handle 2 are arranged in an L shape, and a through first axial hole 10 is arranged on the first rotating handle 2. The lower support plate 3 is located between the two first rotating handles 2, and a second rotating handle 4 is arranged at one end of the lower support plate 3. The lower support plate 3 and the second rotating handle 4 are arranged in an L shape, and a second axial hole 11 is provided at the lower end of the lower support plate 3 and near the second rotating handle 4. The upper support plate 1 and the first rotating handle 2, as well as the lower support plate 3 and the second rotating handle 4 can be integrally formed, or can be fixed as a whole with an adhesive.

[0020] The first axial hole 10 is set at 2 to 3 cm from the upper end of the first rotating handle 2, and the lower support plate 3 is fixed with a connecting plate near the second rotating handle 4. The second axial hole 11 is set on the connecting plate, and the first axial hole 10 and the second axial hole 11 coincide with each other. The rotating shaft 5 passes through and connects the first axial hole 10 and the second axial hole 11, so that the upper support plate 1 and the lower support plate 3 can rotate relative to each other, thereby supporting the upper and lower jaws of the patient. In this way, the upper support plate 1 and the lower support plate 3 can be set at intervals so that there is a certain space between the two to facilitate ventilation of the patient, and it is also convenient for doctors to check or operate in the oral cavity, such as suctioning sputum, collecting throat swabs, etc.

[0021] In order to prevent the upper support plate 1 and the lower support plate 3 from reversing and maintain the expanded state, the oropharyngeal ventilation device is further provided with an angle positioning assembly 9, which is provided at the lower ends of the first rotating handle 2 and the second rotating handle 4, and is used to limit the minimum angle between the upper support plate 1 and the lower support plate 3. Specifically, the angle positioning assembly 9 includes a baffle plate 92 and an adjusting bolt 91, the baffle plate 92 is fixedly connected between the two first rotating handles 2, the second rotating handle 4 is provided with a screw hole 12 opposite to the baffle plate 92, the adjusting bolt 91 is connected to the screw hole 12, and one end of the adjusting bolt 91 is against the baffle plate 92.

[0022] In order to ensure that the oropharyngeal ventilation device is stably stuck in the patient's oral cavity, an upper alveolar 6 with an opening facing upward is provided on the upper support plate 1, and the upper alveolar 6 is located at the end opposite to the first rotating handle 2. A lower alveolar 7 with an opening facing downward is provided on the lower support plate 3, and the lower alveolar 7 is located at the end opposite to the second rotating handle 4. When in use, the patient's upper teeth are placed in the upper alveolar 6, and the lower teeth are placed in the lower alveolar 7, thereby preventing the upper support plate 1 and the lower support plate 3 from moving forward and backward relative to the patient's oral cavity.

[0023] In order to ventilate the patient more effectively and prevent the tongue root from falling back, the lower support plate 3 is provided with a tongue depressor 8 extending forward on the end provided with the lower alveolar 7. The tongue depressor 8 is used to press on the upper end of the tongue, thereby facilitating opening the patient's airway for oropharyngeal ventilation.

[0024] The upper support plate 1 and the lower support plate 3 are made of transparent material, so that the doctor can easily observe the internal conditions of the patient's oral cavity.

[0025] When in use, the upper support plate 1 and the lower support plate 3 are inserted into the patient's oral cavity so that the upper alveolar plate 6 is opposite to the patient's upper teeth, the lower alveolar plate 7 is opposite to the lower teeth, and the tongue depressor 8 is pressed on the tongue. Then the first rotating handle 2 and the second rotating handle 4 are rotated to drive the upper support plate 1 and the lower support plate 3 to rotate relative to each other to support the patient's upper and lower jaws. After the upper support plate 1 and the lower support plate 3 are opened to a suitable angle, the adjusting bolt 91 is rotated so that the end of the adjusting bolt 91 is against the baffle 92. In this way, when the patient applies force to the upper support plate 1 and the lower support plate 3, the upper support plate 1 and the lower support plate 3 will not continue to rotate and cause the patient's oral cavity to close. The oropharyngeal ventilation device can quickly adjust the expansion angle to facilitate use by different patients.

[0026] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
