Abstract
Description
技术领域technical field
本实用新型属于医疗设备技术领域，涉及一种麻醉导管，具体涉及一种可保留自主呼吸的吸入麻醉导管。The utility model belongs to the technical field of medical equipment and relates to an anesthesia catheter, in particular to an inhalation anesthesia catheter capable of retaining spontaneous breathing.
背景技术Background technique
吸入麻醉药经肺通气进入体内和排除，其麻醉深度的调节较其他静脉麻醉药更为容易。吸入麻醉剂如七氟烷，具有良好的镇痛和麻醉作用，且对呼吸抑制轻，能在保留自主呼吸的情况下完成体表和四肢的手术，如前列腺电切术、子宫锥形切除术等；在辅助椎管内麻醉和神经阻滞时，可以完成腹腔镜胆囊切除、肠道肿瘤切除术等的麻醉。Inhaled anesthetics enter the body and are eliminated through pulmonary ventilation, and the adjustment of the depth of anesthesia is easier than other intravenous anesthetics. Inhalation of anesthetics such as sevoflurane has good analgesic and anesthetic effects, and has light respiratory depression, and can complete body surface and limb operations while retaining spontaneous breathing, such as prostate resection, hysterectomy, etc. ; When assisting spinal anesthesia and nerve block, it can complete laparoscopic cholecystectomy, intestinal tumor resection, etc. anesthesia.
目前常用的吸入麻醉工具主要有：面罩、喉罩和气管插管。当行颅脑手术的唤醒麻醉时，采用面罩实施吸入麻醉会因舌后坠等出现上呼吸道梗阻，而采用喉罩或气管插管则会占用患者声门使其无法说话，无法实现患者在手术中与手术医生对话的要求；此外，在行口腔小手术时，若用面罩或喉罩实施吸入麻醉就会占用手术部位，若用气管插管则会用到肌肉松弛药而无法保留患者自主呼吸；目前经鼻非气管插管的气道工具只有鼻咽通气道，但若直接采用鼻咽通气道来实施吸入麻醉，则会患者口鼻未封闭，致使患者呼出的麻醉气体会经口鼻泄漏到手术室，造成污染，而且也无法方便准确地监测呼气末CO2和麻醉气体的浓度。因此目前临床上需要一种可保留自主呼吸且能防止麻醉废气泄漏和保持上呼吸道通畅、方便准确监测呼气末CO2和麻醉气体浓度的吸入麻醉导管。The commonly used inhalational anesthesia tools mainly include: mask, laryngeal mask and endotracheal intubation. When performing wake-up anesthesia for craniocerebral surgery, using a face mask to perform inhalation anesthesia will cause upper airway obstruction due to the tongue falling behind, while using a laryngeal mask or endotracheal intubation will occupy the patient's glottis and make it impossible to speak, and it is impossible for the patient to be able to speak during the operation. The requirement for dialogue with the surgeon; in addition, when performing minor oral surgery, if inhalation anesthesia is performed with a face mask or a laryngeal mask, the surgical site will be occupied, and if a tracheal intubation is used, muscle relaxants will be used, which will prevent the patient from breathing spontaneously; At present, the airway tool for nasal non-tracheal intubation is only the nasopharyngeal airway, but if the nasopharyngeal airway is directly used for inhalation anesthesia, the patient's mouth and nose will not be closed, causing the patient's exhaled anesthetic gas to leak through the mouth and nose. The operating room causes pollution, and it is impossible to conveniently and accurately monitor the concentration of end-tidal CO 2 and anesthetic gas. Therefore, there is currently a clinical need for an inhalation anesthesia catheter that can retain spontaneous breathing, prevent the leakage of anesthesia waste gas, keep the upper airway unobstructed, and facilitate and accurately monitor the concentration of end-tidal CO 2 and anesthetic gas.

本实用新型的目的是提供一种麻醉导管，具体提供一种可保留自主呼吸且能保持上呼吸道通畅和防止麻醉废气泄漏的吸入麻醉导管。The purpose of the utility model is to provide an anesthesia catheter, specifically an inhalation anesthesia catheter that can retain spontaneous breathing, keep the upper airway unobstructed and prevent the leakage of anesthesia waste gas.
本实用新型的目的是通过采用以下技术方案来实现的：一种麻醉导管，包括鼻腔插入端和设备连接端，所述麻醉导管设置有进气管和负压吸引管。使用所述麻醉导管时，将设备连接端的呼吸机连接口和负压吸引器连接口分别连接到相应设备上，将麻醉导管鼻腔插入端经患者鼻腔插入到咽喉部(声门上1-2公分处)，不会占用口腔或颅脑等部位，且麻醉导管的鼻腔插入端端口位于声门上而不经过声门，能让患者在麻醉减浅后说话。进行吸入麻醉的过程中，患者可以保留自主呼吸，吸入由麻醉机导入的麻醉气体和氧气，呼出的CO2和麻醉废气经负压吸引管抽走，这样麻醉气体就不会泄漏到空气中污染环境；此外口腔分泌物或血液也可以被负压吸引管抽走而不会堵塞麻醉导管口或防止其进入气管。作为优选技术方案，负压吸引管的开孔位置设置在麻醉导管靠近插入端端口的外壁上；所述进气管设置在负压吸引管的管腔中，或者负压吸引管设置在进气管的外壁上。The purpose of the utility model is achieved by adopting the following technical scheme: an anesthesia catheter, which includes a nasal cavity insertion end and a device connection end, and the anesthesia catheter is provided with an air intake tube and a negative pressure suction tube. When using the anesthesia catheter, the ventilator connection port and the negative pressure suction device connection port of the equipment connection end are respectively connected to the corresponding equipment, and the nasal cavity insertion end of the anesthesia catheter is inserted into the throat (1-2 cm above the glottis) through the patient's nasal cavity place), it will not occupy the mouth or brain, and the nasal cavity insertion port of the anesthesia catheter is located on the glottis without passing through the glottis, allowing the patient to speak after the anesthesia is reduced. During inhalation anesthesia, the patient can keep breathing spontaneously, inhale the anesthesia gas and oxygen introduced by the anesthesia machine, and the exhaled CO2 and anesthesia waste gas are sucked away through the negative pressure suction tube, so that the anesthesia gas will not leak into the air and pollute Environment; In addition, oral secretions or blood can also be sucked away by the negative pressure suction tube without blocking the anesthesia catheter or preventing it from entering the trachea. As a preferred technical solution, the opening position of the negative pressure suction tube is arranged on the outer wall of the anesthesia catheter near the port of the insertion end; the air intake tube is arranged in the lumen of the negative pressure suction tube, or the negative pressure suction tube is arranged on the outer wall.

When the anesthesia catheter is used for inhalation anesthesia, the CO2 and anesthesia gas exhaled by the patient will reach the monitor through the end-tidal gas concentration monitor connecting tube.
所述麻醉导管上还设置有气囊和气囊导管，气囊设置在麻醉导管靠近插入端端口的外壁上，气囊导管连接在气囊上。优选地气囊为环形，所述气囊导管设置在负压吸引管的内壁上。气囊的作用主要是起支撑作用，通过气囊导管向气囊打气和排气，可以调节气囊的大小以适应不同的患者，防止下坠的舌头等咽部组织阻塞进气管开口和负压吸引管上的开孔，另外还可以阻挡口腔分泌物或血液等流入气管。The anesthesia catheter is also provided with a balloon and a balloon catheter, the balloon is arranged on the outer wall of the anesthesia catheter close to the port of the insertion end, and the balloon catheter is connected to the balloon. Preferably, the air bag is annular, and the air bag catheter is arranged on the inner wall of the negative pressure suction tube. The role of the airbag is mainly to support the airbag through the airbag catheter to inflate and exhaust the airbag. The size of the airbag can be adjusted to suit different patients, preventing the falling tongue and other pharyngeal tissues from blocking the opening of the intake pipe and the opening on the negative pressure suction tube. In addition, it can prevent oral secretions or blood from flowing into the trachea.
