技术领域technical field
本实用新型涉及一种多功能鼻腔气囊式扩张器，尤其涉及一种能够有效进行前后鼻腔止血，鼻腔术后填塞止血，用于鼻孔术后扩张成形，同时保持鼻腔通气功能，减少鼻粘膜摩擦损伤，适合各类临床机构及急救处理广泛使用的多功能鼻腔气囊式扩张医用器械。The utility model relates to a multifunctional nasal cavity air bag dilator, in particular to a device capable of effectively hemostasis in the front and rear nasal cavity, stuffing and hemostasis after nasal cavity surgery, used for expansion and shaping of nostrils after surgery, maintaining nasal cavity ventilation function, and reducing nasal mucosal friction damage , a multi-functional nasal air bag expansion medical device suitable for various clinical institutions and emergency treatment.
背景技术Background technique
鼻腔出血是耳鼻喉科常见疾病，可发生在鼻腔前部或后部，需要立即给予快速有效的止血处理。临床常用止血材料主要为：凡士林纱条、膨胀止血海绵及高分子可吸收止血材料。在治疗过程中可能存在盲目性和过度填塞，导致鼻腔粘膜损伤糜烂，鼻腔继发出血，鼻腔粘连、嗅觉减退等并发症。Nasal bleeding is a common disease in otolaryngology, which can occur in the front or back of the nasal cavity, and requires immediate and effective hemostasis treatment. Commonly used clinical hemostatic materials are mainly: vaseline gauze, expanded hemostatic sponge and polymer absorbable hemostatic materials. During the treatment process, there may be blindness and excessive packing, leading to nasal mucosal damage and erosion, secondary bleeding in the nasal cavity, nasal adhesion, hyposmia and other complications.
尤其是蝶腭动脉等较大分支破裂等导致后鼻孔大出血，往往出血凶猛，临床处理困难，严重时导致失血性休克、误吸，危及生命。目前主要是通过后鼻孔填塞术，传统操作方法繁琐，效果欠佳。由于无法评估局部压力情况，为了保证止血效果，导致局部填塞压力过大，往往伴随明显咽痛、吞咽困难、呼吸困难等不适，甚至导致急性化脓性中耳炎、鼻咽脓肿、颅底骨髓炎等并发症。In particular, the rupture of larger branches such as the sphenopalatine artery leads to massive hemorrhage in the posterior nares, which is often violent and difficult to treat clinically. In severe cases, it can lead to hemorrhagic shock, aspiration, and life-threatening. At present, it is mainly through posterior nostril packing. The traditional operation method is cumbersome and the effect is not good. Due to the inability to assess the local pressure, in order to ensure the hemostatic effect, the local packing pressure is too high, often accompanied by obvious sore throat, dysphagia, dyspnea and other discomfort, and even lead to acute suppurative otitis media, nasopharyngeal abscess, skull base osteomyelitis and other complications disease.
鼻孔成形术后需要使用辅助支撑架，用于鼻孔塑性扩张，防止术后瘢痕挛缩，影响手术效果。目前临床多采用固定大小的筒形支撑架。由于个人差异，往往大小规格不能完全满足临床需求，放置时可能损伤鼻腔粘膜组织，长期放置清洗更换不方便，取出时易粘连，引起患者疼痛、出血。支撑架管径固定，单个型号仅仅起到支撑作用，达不到扩张鼻腔的目的。After rhinoplasty, an auxiliary support frame is required for plastic expansion of the nostrils to prevent postoperative scar contracture and affect the surgical effect. At present, a cylindrical support frame with a fixed size is mostly used clinically. Due to individual differences, the size and specifications often cannot fully meet the clinical needs, and the nasal mucosa may be damaged when placed. It is inconvenient to clean and replace after long-term placement, and it is easy to stick when taken out, causing pain and bleeding in patients. The diameter of the support frame is fixed, and a single model only plays a supporting role, and cannot achieve the purpose of expanding the nasal cavity.

本实用新型的工作原理和工作过程：1.应用在患者鼻出血、鼻腔术后止血的情况时：Principle of work and working process of the present utility model: 1. When being applied in the situation of patient's epistaxis, postoperative hemostasis of nasal cavity:
患者取坐位或半卧位，将鼻腔血凝块尽量清除，使用含丁卡因和呋麻棉片收缩鼻腔粘膜，行局部麻醉。在鼻咽部气囊2和鼻腔气囊3表面可涂抹止血药物或放置可溶性止血纱布。将本器械经患侧鼻腔总鼻道送入鼻咽部。观察中央通气管1刻度标示，插入深度约10～13cm，经口腔在咽后壁可看到为准。The patient is placed in a sitting or semi-recumbent position, and the blood clot in the nasal cavity is removed as much as possible. The nasal mucosa is shrunk with cotton pads containing tetracaine and furan, and local anesthesia is performed. On the surface of nasopharyngeal air bag 2 and nasal cavity air bag 3, hemostatic drugs can be applied or dissolvable hemostatic gauze can be placed. Send the device into the nasopharynx through the common nasal passage of the affected side. Observe the scale marks on the central ventilation tube 1, the insertion depth is about 10-13 cm, whichever can be seen on the posterior pharyngeal wall through the oral cavity.
将采用普通医用注射器作为充排气装置，将其注射口端插入弹簧式充排气阀，顶开阀门，经导气管对鼻咽部气囊2注入空气10～20ml，使其充盈。然后将中央导气管回拉，将鼻咽部气囊2拉到后鼻孔至无法拉动固定。再使用医用注射器经导气管对鼻腔气囊3注入空气30～40ml,使其充盈。根据患者出血情况，观察鼻咽部压力检测气囊6和鼻腔压力检测气囊9的压力值，适当增减鼻咽部气囊2和鼻腔气囊3内的空气，达到良好止血效果，同时降低患者不适感；最后将本器械鼻外部分用胶布固定于面颊部，止血完成。A common medical syringe will be used as the inflation and exhaust device, insert the injection port into the spring-type inflation and exhaust valve, open the valve, and inject 10-20ml of air into the nasopharyngeal air bag 2 through the airway to make it inflate. Then the central airway is pulled back, and the nasopharyngeal air bag 2 is pulled to the posterior nostril until it cannot be pulled and fixed. Then use a medical syringe to inject 30-40 ml of air into the nasal cavity air bag 3 through the airway to make it full. According to the bleeding situation of the patient, observe the pressure values of the nasopharyngeal pressure detection airbag 6 and the nasal cavity pressure detection airbag 9, and appropriately increase or decrease the air in the nasopharyngeal airbag 2 and the nasal cavity airbag 3, so as to achieve a good hemostatic effect and reduce the discomfort of the patient; Finally, fix the outer part of the instrument on the cheek with adhesive tape, and the hemostasis is completed.
插管后48小时，如果出血停止，即可准备拔管。拔管前先将鼻咽部气囊2和鼻腔气囊3内的空气抽出，观察鼻腔是否停止出血。然后再将导管拔出，最终确认止血成功。对于出血凶猛的患者，可分2～3次抽出鼻咽部气囊2和鼻腔气囊3内空气，逐渐降低气囊对出血点的压迫作用，达到止血目的。48 hours after intubation, if the bleeding has stopped, you are ready for extubation. Before extubation, the air in the nasopharyngeal air bag 2 and the nasal cavity air bag 3 is drawn out to observe whether the nasal cavity stops bleeding. Then the catheter was pulled out, and the hemostasis was finally confirmed. For patients with severe bleeding, the air in the nasopharyngeal air bag 2 and the nasal cavity air bag 3 can be extracted 2 to 3 times to gradually reduce the pressure of the air bag on the bleeding point and achieve the purpose of hemostasis.
由于中央通气管硬度适中，不会因受压导致阻塞通气。如果由于鼻腔分泌物或血凝块造成阻塞，可以在中央通气管1外侧端接吸引器，将其清除。对于需要吸氧的患者，可以在中央通气管1外侧端接吸氧管，保证患者吸氧需求。Due to the moderate hardness of the central ventilation tube, the ventilation will not be blocked due to pressure. If the blockage is due to nasal secretions or blood clots, it can be removed with an aspirator terminated on the outside of the central vent tube 1 . For patients who need to inhale oxygen, an oxygen inhalation tube can be terminated outside the central ventilation tube 1 to ensure the oxygen inhalation demand of the patient.
2.应用在鼻孔成形术后：2. Application after rhinoplasty:
根据鼻孔成形术后要求，选择鼻咽部气囊2或鼻腔气囊3作为术后辅助支撑架，用于鼻孔塑性扩张。鼻腔粘膜局部麻醉后，在中央通气管1刻度标识辅助下将本器械置入鼻腔深部，将选择的气囊充盈。按照术后鼻孔塑性扩张的需要，通过观察压力检测气囊调整气囊的压力值，达到扩张术后鼻孔的目的，避免术后瘢痕挛缩。最后将本器械鼻外部分用胶布固定于面颊部。According to the requirements after rhinoplasty, nasopharyngeal air bag 2 or nasal cavity air bag 3 is selected as the postoperative auxiliary support frame for plastic expansion of nostrils. After local anesthesia of the nasal mucosa, the device is inserted into the deep part of the nasal cavity with the aid of the 1 scale mark of the central ventilation tube, and the selected air bag is inflated. According to the needs of postoperative nostril plastic expansion, the pressure value of the airbag is adjusted by observing the pressure detection airbag, so as to achieve the purpose of postoperative nostril expansion and avoid postoperative scar contracture. Finally, fix the outer part of the instrument on the cheek with adhesive plaster.
由于中央通气管1不影响正常鼻腔通气，置入本器械后可长期带管。同时可通过定期观察压力检测气囊的压力值，了解气囊对鼻孔扩张作用效果，必要时经充排气阀增减空气，调整气囊的压力。充分满足鼻孔成形术后需要长时间支撑扩张要求。Since the central ventilation tube 1 does not affect the normal nasal cavity ventilation, it can be worn for a long time after the device is inserted. At the same time, the pressure value of the airbag can be detected by regularly observing the pressure to understand the effect of the airbag on the expansion of the nostrils. If necessary, the air can be increased or decreased through the inflation and exhaust valve to adjust the pressure of the airbag. Fully meet the requirements of long-term support and expansion after rhinoplasty.
