Description
技术领域： Technical field:
本实用新型涉及人类生活用品，尤其涉及医疗器械，特别涉及全身麻醉或面罩通气时的辅助用具，具体的是一种口面部支撑装置。The utility model relates to articles for human life, in particular to medical instruments, in particular to auxiliary appliances for general anesthesia or mask ventilation, in particular to an orofacial support device.
背景技术： Background technique:
麻醉医学的临床治疗中，对于老年病患，在面罩给予纯氧和正压通气的过程中有时会出现通气不足，致使麻醉前SPO2＞90％的病人无法维持SPO2＞90％以上。老年人发生面罩通气困难的主要原因是缺齿。这主要是因为唇颊部因失去硬组织的支持，向内凹陷，上唇丰满度丧失，面部皱褶增加，口角下陷，面下1/3距离变短，从而导致面罩无法与面形紧密贴合，造成面罩通气困难。同时，由于牙列缺失，舌失去牙的限制，因而伸展扩大，严重者可造成舌形态的改变和功能失常，且可导致舌与颊部内陷的软组织接触，使整个口腔为舌所充满，在麻醉诱导后常发生舌根后坠，阻塞通气道，这是造成老年患者通气困难的另一主要原因。目前对无齿老年患者进行面罩通气，主要是通过在面罩周围填塞纱布，或将假牙保留在原位以解决面罩通气困难，但效果不理想，且保留假牙在原位有导致患者损伤、阻塞气道等危险。另外，也不能解决麻醉诱导后舌根后坠的问题。In the clinical treatment of anesthesia medicine, for elderly patients, hypoventilation sometimes occurs during the process of giving pure oxygen and positive pressure ventilation by face masks, so that patients with SPO2>90% before anesthesia cannot maintain SPO2 >90%. The main cause of face mask ventilation difficulties in the elderly is edentulousness. This is mainly because the lips and cheeks are sunken inward due to the loss of hard tissue support, the fullness of the upper lip is lost, facial wrinkles are increased, the corners of the mouth are sunken, and the distance of the lower 1/3 of the face is shortened, which makes the mask unable to fit the face shape tightly. , causing difficulty in mask ventilation. At the same time, due to the lack of dentition, the tongue loses the restriction of the teeth, so it stretches and expands. In severe cases, it can cause changes in the shape and dysfunction of the tongue, and it can cause the tongue to contact the soft tissue recessed in the cheek, so that the entire oral cavity is filled with the tongue. After induction of anesthesia, the base of the tongue often falls back and blocks the airway, which is another major cause of ventilation difficulties in elderly patients. At present, face mask ventilation is performed on edentulous elderly patients, mainly by stuffing gauze around the mask, or keeping the dentures in place to solve the difficulty of mask ventilation, but the effect is not ideal, and keeping the dentures in place will cause damage to the patient and obstruct the airway. Road and other dangers. In addition, it cannot solve the problem of tongue root falling back after induction of anesthesia.
发明内容： Invention content:
本发明的目的在于提供一种口面部支撑装置，所述的这种口面部支撑装置要解决现有技术中麻醉面罩使用于缺齿老年患者时通气不足、产生麻醉风险的技术问题。The purpose of the present invention is to provide an orofacial support device, which solves the technical problems of insufficient ventilation and anesthesia risk when anesthesia masks are used for edentulous elderly patients in the prior art.
本实用新型的一种口面部支撑装置，由一个口面部支撑器和一个口咽通气管道构成，所述的口面部支撑器呈蝶状向两侧延伸，口面部支撑器的中部设置有一个通气管道，所述的口咽通气管道设置在所述的通气管道内，口咽通气管道的长度大于口面部支撑器的长度，口咽通气管道的外径与通气管道的内径相配合，口咽通气管道的后部在口面部支撑器的后端穿出后呈弧状弯曲。An orofacial support device of the present utility model is composed of an orofacial support and an oropharyngeal ventilator. The orofacial support extends to both sides in a butterfly shape, and a ventilator is arranged in the middle of the orofacial support. pipeline, the oropharyngeal ventilation pipeline is set in the ventilation pipeline, the length of the oropharyngeal ventilation pipeline is greater than the length of the orofacial support, the outer diameter of the oropharyngeal ventilation pipeline matches the inner diameter of the ventilation pipeline, and the oropharyngeal ventilation pipeline The rear portion of the duct is curved in an arc after passing through the rear end of the orofacial support.
进一步的，所述的通气管道的径向截面呈扁圆状。Further, the radial section of the air duct is oblate.
进一步的，所述的口咽通气管道的前端面上通过螺钉连接有一个旋转限位片。Further, a rotation limiting piece is connected to the front end surface of the oropharyngeal airway through screws.
进一步的，通气管道两侧的蝶状延伸部分上对称设置有孔。Further, holes are symmetrically arranged on the butterfly-shaped extension parts on both sides of the air duct.
本实用新型的工作过程是：患者除去假牙，然后常规麻醉诱导，当患者自主呼吸消失后，将口内支撑器正面朝上置入患者口腔内(口唇与牙槽之间)，进行通气，如果通气仍然不理想，在所述的通气管中插入口咽通气管道，将旋转片固定于通气管外，以避免口咽通气管道插入过深，再继续进行通气，完成“驱氮给氧”过程后，将口内支撑器取出，进行气管插管。The working process of the utility model is as follows: the patient removes the dentures, and then induces conventional anesthesia. After the patient's spontaneous breathing disappears, the intraoral support is put into the patient's oral cavity (between the lips and the alveolar) with the front facing up, and ventilation is performed. Still unsatisfactory, insert the oropharyngeal ventilation tube into the ventilation tube, fix the rotating piece outside the ventilation tube to avoid the oropharyngeal ventilation tube from being inserted too deep, and then continue ventilation, after completing the process of "expelling nitrogen and supplying oxygen" , the intraoral support was taken out, and the endotracheal intubation was performed.
本实用新型与已有技术相对照，其效果是积极和明显的。本实用新型的口面部支撑器可显著改善无齿老年患者通气的效果，大大降低通气困难的发生率，并且不会造成通气道的阻塞，一定程度上确保了麻醉安全。另外，安放与去除十分方便，减少了病人无通气状态的时间，同时避免了保留假牙给患者造成潜在的副损伤。口面部支撑器的制作工艺简单，成本低廉，一次性使用，适合广泛应用于各级医院麻醉科及呼吸科老年患者无创通气治疗。Compared with the prior art, the utility model has positive and obvious effects. The orofacial supporter of the utility model can significantly improve the ventilation effect of edentulous elderly patients, greatly reduce the incidence of ventilation difficulties, and will not cause obstruction of the ventilation passage, thereby ensuring the safety of anesthesia to a certain extent. In addition, it is very convenient to place and remove, which reduces the time of the patient in the non-ventilated state, and avoids potential secondary damage to the patient caused by retaining the dentures. The manufacturing process of the orofacial support is simple, the cost is low, and it is disposable, and it is suitable for non-invasive ventilation treatment of elderly patients in anesthesiology and respiratory departments of hospitals at all levels.
