Description
技术领域technical field
本实用新型涉及外科手术医疗器械领域，更具体的说，是一种家兔自主呼吸麻醉下的简易吸氧面罩。The utility model relates to the field of surgical medical instruments, in particular to a simple oxygen inhalation mask for rabbits under spontaneous breathing anesthesia.
背景技术Background technique
随着自主呼吸麻醉技术在胸科手术中的广泛应用，目前胸外科手术可选择的麻醉方式多样，深入研究与自主呼吸麻醉下胸外科手术期间相关的机体病理生理改变，阐明发病机制，有利于指导临床进一步对手术麻醉方式的选择。兔的呼吸系统解剖及主要生理指标与人体相近，且来源广泛，生存能力较强，是研究自主呼吸麻醉胸外科手术的理想动物。经鼻和口面罩给氧，能够保证自主呼吸麻醉下足够的供氧，以维持相对较长手术时间。但兔的口和鼻外形特殊，没有专用的鼻导管或给氧面罩，也没有专用的喉罩。With the widespread application of spontaneous breathing anesthesia technology in thoracic surgery, there are currently various anesthesia methods available for thoracic surgery. It is beneficial to study the pathophysiological changes of the body related to thoracic surgery under spontaneous breathing anesthesia and clarify the pathogenesis. To guide the clinical selection of further surgical anesthesia. The anatomy and main physiological indicators of the rabbit's respiratory system are similar to those of the human body, and it has a wide range of sources and strong viability. It is an ideal animal for studying spontaneous breathing anesthesia in thoracic surgery. Oxygen supply through the nose and mouth mask can ensure sufficient oxygen supply under spontaneous breathing anesthesia to maintain a relatively long operation time. However, the shape of the mouth and nose of rabbits is special, and there is no special nasal cannula, oxygen mask, or special laryngeal mask.
实用新型内容Utility model content
针对现有技术存在的不足，本实用新型的目的在于提供一种家兔自主呼吸麻醉下的简易吸氧面罩，主要适用于家兔非气管插管自主呼吸麻醉手术过程中保证家兔氧气的的供应。In view of the deficiencies in the prior art, the purpose of this utility model is to provide a simple oxygen inhalation mask for rabbits under spontaneous breathing anesthesia, which is mainly suitable for ensuring the oxygen of rabbits during non-tracheal intubation spontaneous breathing anesthesia. supply.
本实用新型的目的通过下述技术方案实现：The purpose of this utility model is achieved through the following technical solutions:
本实用新型的一种家兔自主呼吸麻醉下的简易吸氧面罩由膨大部分和尾部组成，所述膨大部分和所述尾部连为一体。The utility model relates to a simple oxygen inhalation mask for rabbits under spontaneous respiration anesthesia.
优选的，所述膨大部分为中空结构，开口为直径3cm的圆口。Preferably, the enlarged part is a hollow structure, and the opening is a round mouth with a diameter of 3 cm.
优选的，所述膨大部分的侧壁上有圆孔。Preferably, there is a round hole on the side wall of the enlarged part.
优选的，所述圆孔直径为2mm。Preferably, the diameter of the circular hole is 2mm.
优选的，所述圆孔为3个。Preferably, there are three circular holes.
优选的，所述面罩的两侧设有固定带。Preferably, two sides of the mask are provided with fixing straps.
使用时，本实用新型的面罩尾部与输氧导管相连，输氧导管上安装有输氧单向阀。氧气经狭窄的尾部进入面罩膨大处，由于喷射入面罩的气流大于兔吸气时的最高流速和潮气量，所以吸氧浓度恒定，因高流速的气体不断冲洗面罩内部，面罩上的小孔可以排出气体，兔呼出的气体难以在面罩中滞留，因此，基本无重复呼吸。During use, the mask tail of the utility model is connected with the oxygen delivery conduit, and the oxygen delivery check valve is installed on the oxygen delivery conduit. Oxygen enters the enlarged part of the mask through the narrow tail. Since the airflow injected into the mask is greater than the maximum flow rate and tidal volume when the rabbit inhales, the concentration of oxygen inhalation is constant. Because the high-velocity gas continuously washes the inside of the mask, the small holes on the mask can Exhaust gas, the gas exhaled by the rabbit is difficult to stay in the mask, so there is basically no rebreathing.
本实用新型的简易吸氧面罩能够保证自主呼吸麻醉过程中非气管插管状态下保证手术过程中足够的供氧，在保证家兔麻醉安全性的前提下满足实验人员各种基础实验的需求，可以深入研究与自主呼吸麻醉下各种外科手术间相关的机体病理生理改变，阐明发病机制，有利于指导临床进一步对手术麻醉方式的选择。The simple oxygen inhalation mask of the utility model can ensure sufficient oxygen supply during the operation process in the non-tracheal intubation state during the spontaneous breathing anesthesia process, and meet the needs of various basic experiments of the experimenters on the premise of ensuring the safety of rabbit anesthesia. It can deeply study the pathophysiological changes of the body related to various surgical operations under spontaneous breathing anesthesia, clarify the pathogenesis, and help guide the selection of further clinical anesthesia methods.
本实用新型的简易吸氧面罩操作省时、方便灵活；使家兔不用气管切开或者气管插管情况下进行自主呼吸麻醉手术。The simple oxygen inhalation mask of the utility model is time-saving, convenient and flexible in operation; it enables rabbits to perform spontaneous breathing anesthesia operation without tracheotomy or trachea intubation.
