经鼻插管防护装置Nasal intubation protection device

技术领域technical field

本发明属于医疗用品领域，具体地说涉及经鼻插管防护装置。The invention belongs to the field of medical supplies, in particular to a protective device for nasal intubation.

背景技术Background technique

目前患者全身麻醉后，患者呼吸的方式主要是“经鼻插管”和“经口插管”进行辅助呼吸，呼吸机通过插管向患者肺部输气。再行口腔颌面外科手术的过程中，经口插管会导致手术的视野受限，绝大多数情况下，都会选择经鼻插管。但是再行上颌骨肿瘤的切除时，我们会切除部分上颌骨，甚至全切以及扩大切除，常常会切过腭中缝到对侧。At present, after the patient is under general anesthesia, the patient's breathing method is mainly "nasal intubation" and "oral intubation" for assisted breathing, and the ventilator delivers air to the patient's lungs through the intubation. In the process of oral and maxillofacial surgery, oral intubation will result in limited surgical field of view, and in most cases, nasal intubation will be chosen. However, when performing maxillary tumor resection, we will resect part of the maxilla, or even complete resection and extended resection, and often cut through the midpalatal suture to the opposite side.

在使用来福锯或者电钻磨头行上颌骨切除时，常常会损伤到经鼻插入的输气插管，机械刺激产生的热量甚至可能会通过插管输气传递至肺部，导致肺部灼伤。现临床中无保护经鼻插管的装置，外科医师很大程度上还是通过经验来判断，这样也会增加损伤插管的风险。另外，不同患者鼻腔孔径的大小存在差异，如何有效保护插管仍需解决。When using a rifle saw or an electric drill for maxillary resection, the air intubation inserted through the nose is often damaged, and the heat generated by mechanical stimulation may even be transmitted to the lungs through the intubation air, resulting in lung burns . There are currently unprotected nasal intubation devices in clinical practice, and surgeons largely rely on experience to judge, which will also increase the risk of intubation damage. In addition, there are differences in the size of the nasal cavity in different patients, and how to effectively protect the intubation still needs to be solved.

It can be seen from the above structure that thearc tube 2, thearc opening 4, thearc column 6, and thearc arch plate 5 maintain the same axis, so that thearc column 6 can be rotated from the end of thearc tube 2 to thearc tube 2 Inside, and thearc arch plate 5 rotates along thearc opening 4. The rods of the twobolts 3 are provided with external threads, and the inner walls at both ends of thearc tube 2 are provided with internal threads. position, to prevent thearc column 6 from rotating arbitrarily with thearc arch plate 5. The detachable structure can facilitate the replacement ofarc arch plates 5 of different lengths, so as to adapt to the nasal cavity depths of different patients. The surgeon can adjust the position of the arc-shaped tube 2 through thehandle 1, thereby adjusting the positions of the arc-shaped arch plate 5 and the arc-shaped post 6. The arc-shaped opening 4 completely extends to both ends of the arc-shaped tube 2 .

进一步的，所述圆弧拱板5包括左圆弧拱板7和右圆弧拱板8；所述弧形柱6包括位于左圆弧拱板7一端的左弧形柱9和位于右圆弧拱板8一端的右弧形柱10；所述左弧形柱9和右弧形柱10断开设置；所述左圆弧拱板7靠近右圆弧拱板8侧设有上搭接板11；所述右圆弧拱板8靠近左圆弧拱板7侧设有下搭接板12；所述上搭接板11搭接在下搭接板12上侧；所述下搭接板12上侧设有弹性橡胶条13；所述上搭接板11抵靠弹性橡胶条13。由上述结构可知，圆弧拱板5是由左圆弧拱板7和右圆弧拱板8拼接而成，当圆弧拱板5整体宽度需要调大一点时，两个螺栓3向外旋出一点，这样左弧形柱9和右弧形柱10所在空间增加，由于上搭接板11抵靠弹性橡胶条13，弹性橡胶条13位于下搭接板12上侧，弹性橡胶条13的弹力使左圆弧拱板7和右圆弧拱板8有排开的趋势，从而左弧形柱9和右弧形柱10有排开的趋势，左弧形柱9一端继续顶到一个螺栓3，右弧形柱10一端继续顶到另一个螺栓3，圆弧拱板5整体宽度增加。当圆弧拱板5整体宽度需要调小一点时，两个螺栓3向弧形管2端内旋入一点，这样左弧形柱9和右弧形柱10所在空间减小，由于上搭接板11抵靠弹性橡胶条13，弹性橡胶条13位于下搭接板12上侧，左圆弧拱板7和右圆弧拱板8靠近使弹性橡胶条13进一步压缩，从而左弧形柱9和右弧形柱10仍有排开的趋势，左弧形柱9一端继续顶到一个螺栓3，右弧形柱10一端继续顶到另一个螺栓3，圆弧拱板5整体宽度减小。圆弧拱板5整体宽度大小可调，使圆弧拱板5可以适配不同患者鼻腔孔径。Further, thearc arch 5 includes aleft arc arch 7 and aright arc arch 8; thearc column 6 includes aleft arc column 9 at one end of theleft arc arch 7 and aright arc column 9 Theright arc column 10 at one end of thearc arch plate 8; theleft arc column 9 and theright arc column 10 are disconnected; the leftarc arch plate 7 is provided with an upper lap near the rightarc arch plate 8plate 11; the rightarc arch plate 8 is provided with alower lapping plate 12 near the leftarc arch plate 7; theupper lapping plate 11 is lapped on the upper side of thelower lapping plate 12; the lower lapping plateElastic rubber strips 13 are provided on the upper side of 12; It can be seen from the above structure that thearc arch 5 is spliced by theleft arc arch 7 and theright arc arch 8. When the overall width of thearc arch 5 needs to be increased a little, the twobolts 3 are turned outward. A little bit, the space where theleft arc column 9 and theright arc column 10 are located increases like this, because theupper lapping plate 11 is against theelastic rubber strip 13, theelastic rubber strip 13 is positioned at thelower lapping plate 12 upper side, and theelastic rubber strip 13 The elastic force makes the leftarc arch plate 7 and the rightarc arch plate 8 tend to be spaced apart, so that theleft arc column 9 and theright arc column 10 tend to be spaced apart, and one end of theleft arc column 9 continues to push against abolt 3. One end of theright arc column 10 continues to push against anotherbolt 3, and the overall width of thearc arch plate 5 increases. When the overall width of thearc arch plate 5 needs to be adjusted a little smaller, the twobolts 3 are screwed into the end of the arc tube 2 a little, so that the space where theleft arc column 9 and theright arc column 10 are located is reduced. Theplate 11 is against theelastic rubber strip 13, and theelastic rubber strip 13 is located on the upper side of thelower lap plate 12. The leftarc arch plate 7 and the rightarc arch plate 8 are close to make theelastic rubber strip 13 further compressed, so that theleft arc column 9 Andright arc post 10 still has the trend of rowing away, andleft arc post 9 one ends continue to push to abolt 3, andright arc post 10 one ends continue to push to anotherbolt 3, and the overall width ofarc arch plate 5 reduces. The overall width of thearc arch 5 is adjustable, so that thearc arch 5 can be adapted to the nasal cavity diameters of different patients.

进一步的，左圆弧拱板7和右圆弧拱板8所有边缘设有倒圆角。由上述结构可知，倒圆角避免左圆弧拱板7和右圆弧拱板8具有锋利处，图中虽未示意出，实际加工均需要进行倒圆角，保证装置使用的安全，不会戳伤鼻腔。Further, all edges of theleft arc arch 7 and theright arc arch 8 are rounded. It can be seen from the above structure that the rounding avoids the sharpness of theleft arc arch 7 and theright arc arch 8. Although it is not shown in the figure, the actual processing requires rounding to ensure the safety of the device. poke the nasal cavity.
