可弯曲式表面麻醉注药器

Flexible surface-anesthesia medicine injector

Abstract

本实用新型涉及一种可弯曲式表面麻醉注药器,属于医疗器械领域。可有效解决病人清醒时气管插管或纤支镜检查需要在口咽腔、鼻腔、气管部位表面麻醉的问题。它是由注药管、三通开关、注射器三部分组成。注药管壁内有金属丝,注药管一端与三通开关连接;三通开关由底座和手柄组成,手柄内有药液通道,可随手柄180°旋转,底座上有外丝扣;注射器头部为双层结构,外壁上有内丝扣,便于与三通开关上的外丝扣联接。在病人需要口咽腔、鼻腔、气管内表面麻醉时,根据口咽腔、鼻腔、气管曲度将注药管弯曲到合适角度伸入口咽腔、鼻腔、气管内,保证麻药均匀注入各个部位。且简便、易行、安全、可靠。
The utility model relates to a flexible surface-anesthesia medicine injector, which belongs to the field of medical equipment and can be used for effectively performing surface anesthesia on the oropharyngeal cavity, the nasal cavity and the trachea of a waked patient during tracheal intubation or bronchoscopy. The flexible surface-anesthesia medicine injector consists of a medicine injection tube, a three-way switch and an injector, wherein a metal wire is arranged in the wall of the medicine injection tube, and one end of the medicine injection tube is connected with the three-way switch; the three-way switch comprises a base and a handle, a liquid medicine channel is arranged in the handle and can rotate with the handle by 180 degrees, and an outer screw thread is arranged on the base; the head part of the injector is of a dual-layer structure, and an inner screw thread is arranged on the outer wall of the head part of the injector and can be connected with the outer screw thread on the three-way switch conveniently. When the surface anesthesia needs to be performed on the inner surface of the oropharyngeal cavity, the nasal cavity and the trachea of the patient, the medicine injection tube extends into the oropharyngeal cavity, the nasal cavity and the trachea of the patient after being bent to a proper angle according to the curvature of the oropharyngeal cavity, the nasal cavity and the trachea of the patient, so that anesthetic is uniformly injected into each part. The flexible surface-anesthesia medicine injector is simple, convenient, safe and reliable and is easy to operate.
