Safety sputum aspirator for emergency internal medicine

Abstract

The invention discloses a safety sputum aspirator for emergency internal medicine, and belongs to the field of medical instruments. The sputum aspirator comprises a movable protection cabin, rollers,a rotary opening and closing self-lubricating suction head, a sputum suction cavity, a connecting pipe and a hydrodynamic sputum suction driving device, wherein the movable protection cabin is of a cuboid hollow cavity structure, the rollers are symmetrically arranged on a bottom wall of the movable protection cabin, the sputum suction cavity is arranged on an upper wall of the movable protectioncabin and close to an end part of the movable protection cabin, the connecting pipe is arranged on the upper wall of the sputum suction cavity and is communicated with the sputum suction cavity, the rotary opening and closing self-lubricating suction head is arranged at an end part, far away from the sputum suction cavity, of the connecting pipe, the hydrodynamic sputum suction driving device is arranged in the movable protection cabin and is arranged close to the sputum suction cavity, and the hydrodynamic sputum suction driving device is connected to the sputum suction cavity. The sputum aspirator is used for sucking sputum by extending a spherical suction head with self-lubricating and self-heating functions into a throat, generating mild and adjustable negative pressure through drainage, and preventing the throat of a patient from being injured.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a safety sputum suction device for emergency internal medicine. Background technique [0002] The sputum suction device is mainly used for routine sputum suction and tracheotomy for the wounded and sick. The sputum suction device is divided into electric type and manual type. The general electric type sputum suction device has the advantages of small size, light weight, large attraction, Compact structure, easy to carry, low cost, sturdy and durable, etc. Manual sputum suction device can only perform simple work of suctioning sputum, and cannot adjust the suction speed, and the safety is not high. At the same time, the throat is relatively fragile. The suction head is easy to hurt the throat. [0003] The patent application with the patent number CN107583114A discloses a fast and safe sputum suction device for emergency internal medicine, including a negative pressure bo...
