Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.
Embodiment one:
As shown in fig. 1, the embodiment provides an oropharynx air duct, which comprises a tube body 1 and a retainer ring 2, wherein the tube body 1 and the retainer ring 2 are made of sterile medical silica gel.
The tube body 1 consists of an oral cavity part 101 and a throat part 102, and the retainer ring 2 is arranged at the front end of the oral cavity part 101 to play a limiting role and prevent the tube body from completely sinking into the oral cavity of a patient; a circle of biting pad made of silica gel is arranged at the position, 1-1.5 cm behind the retainer ring 2, of the oral cavity part 101, the biting pad 3 is a groove biting pad 3, the groove biting pad 3 is in a ring shape, the groove biting pad 3 is detachably sleeved outside the tube body 1, the groove biting pad 3 is in contact connection with the tube body 1 through friction force, a groove is formed in the outer ring of the groove biting pad 3, the groove biting pad 3 is matched with the biting position of teeth of a patient in use, and upper and lower incisors of the patient are clamped into the grooves of the biting pad, so that the effect of preventing the tube body 1 from moving and preventing the tube body 1 from being damaged when the patient bites is achieved.
The existing oropharynx airway is usually formed by combining a tube body 1 and a retainer ring 2, but in actual use, a patient often has a fear of tension or self-stress reaction of the human body to spit out or bite the tube body 1, so that the channel is blocked after the tube body 1 is pressed, and normal ventilation treatment cannot be performed; in addition, the patient bites the tube body 1, so that the tube body 1 is seriously worn and cannot be used for multiple times, the medical cost is increased, and finally, the burden is caused to hospitals and patients; in this embodiment, the oral cavity portion 101 of the tube body 1 is detachably sleeved with a circle of the concave groove bite pad 3, and when the oropharynx airway is used, the upper and lower incisors of the patient are clamped into the concave grooves, so that the tube body 1 can be prevented from moving, and the tube body 1 can be prevented from being damaged when the patient bites. When the groove biting pad 3 is damaged due to multiple biting, the groove biting pad 3 can be continuously used only by replacing the groove biting pad 3, the whole oropharynx airway is not required to be discarded, and therefore loss of the oropharynx airway is reduced.
Embodiment two:
As shown in fig. 2 to 3, this embodiment is a preferred scheme of the bite pad in the first embodiment, and provides an oropharyngeal airway, in which the bite pad is a dental tray bite pad 4, the entire dental tray bite pad 4 is made of solid silica gel, the dental tray bite pad 4 includes two upper and lower semicircular bite surfaces, an included angle between the two bite surfaces is 40 °, the front end of the dental tray bite pad 4 is 3 cm, the embodiment is suitable for common adults, the cavity opening and closing distance of the normal adult is 3 to 5cm, and the dental tray bite pad with the front end of 3 cm is suitable for most adults. When the embodiment is put into the oral cavity of a patient, the dental tray bite pad 4 is positioned at the biting position of the patient, the dental tray bite pad 4 is attached to the teeth of the patient, the movement of the tube body 1 is avoided, and the oral cavity of the patient is propped up to a comfortable opening and closing angle of the oral cavity.
In the prior art, after the oropharynx airway is put into the oral cavity, the patient needs to open the mouth to keep the oropharynx airway smooth at any time, which leads to long-time tension fatigue of oral muscles of the patient, which not only causes burden to the patient, but also causes tension of the patient to be uneasy, can not be relaxed, even has strong rejection and stress response, and causes danger in the treatment process. Although the recess bite pad 3 in the first embodiment can be fitted to the teeth of the patient to prop open the mouth, only the upper and lower incisors of the patient are in contact with the recess bite pad 3, the contact point is small, and the oral support for the patient is limited. The teeth are supported by the dental tray bite pad 4 in the embodiment, so that the supporting area is increased, the pressure of opening the oral cavity of a patient is further relieved, and the comfort level of the patient is improved.
In addition, arc-shaped tooth support grooves 401 corresponding to the tooth profile of a patient are formed in the two occlusal surfaces of the embodiment, 16 tooth grooves 402 are formed in the upper tooth support groove 401 and the lower tooth support groove 401 respectively, 32 tooth grooves 402 are formed in the total, each tooth groove 402 comprises a large tooth groove and a small tooth groove, the small tooth grooves correspond to the incisors and the cuspids, the large tooth grooves correspond to the groove teeth, the effect of further fitting the tooth shape of the patient is achieved, the movement of the tube body 1 is avoided, the occlusal comfort level is improved, the stress of the patient is further avoided, and the operation effect is improved.
When the dental tray bite pad is used, in the process of plugging the oropharynx channel into the oropharynx of a patient, the dental tray bite pad 4 is folded by hands and then put into the oral cavity of the patient, and the dental tray bite pad 4 can be unfolded by the elasticity of silica gel and attached to the occlusal position of the teeth of the patient in the oral cavity.
Embodiment III:
As shown in fig. 4 to 6, the present embodiment is a preferred scheme of the dental tray bite pad 4 in the second embodiment, the inside of the dental tray bite pad 4 in the present embodiment is a hollow structure, the front end of the dental tray bite pad 4 is provided with an air charging port 404 and an air discharging port 403, a one-way valve is disposed in the air charging port 404, and a plug is disposed on the air discharging port 403. In the second embodiment, the dental tray bite pad 4 is of a solid structure, and needs to be folded when in use to be put into the oral cavity of a patient, and the angle of the upper occlusal surface and the lower occlusal surface of the dental tray bite pad 4 cannot be adjusted, so that the dental tray bite pad cannot be perfectly adapted to different sizes of the oral cavity of the patient.
The dental tray bite pad 4 of the embodiment adopts an inflatable hollow structure, when in use, after the dental tray bite pad 4 is put into the oral cavity of a patient, the dental tray bite pad 4 is inflated by the air pump 5 through the inflation inlet 404 until the oral cavity of the patient is opened to the most comfortable angle, and then the inflation is stopped; when the dental tray bite pad 4 is taken out, the plug of the exhaust port 403 is pulled out to release air, so that the dental tray bite pad can be easily taken out.
