Auxiliary device for sputum adsorption of elderly respiratory medicine department

Abstract

The invention belongs to the technical field of medical instruments, and discloses an auxiliary device for sputum adsorption of the elderly respiratory medicine department. The auxiliary device comprises a sputum suction tube, wherein a through hole is formed in the bottom end of the sputum suction tube, a one-way valve is arranged at the other end of the sputum suction tube, a negative pressure cavity is formed in the left side of the one-way valve, and an L-shaped tube communicates with the left side of the one-way valve. When the sputum suction device is in use, after the sputum suction tube extends into the position, where sputum needs to be sucked, in the respiratory tract of a patient, the sputum suction tube can be effectively prevented from slipping off from the respiratory tract of the patient through an anti-slipping assembly, and then a pull rod and a piston are driven to move rightwards by drawing a handle, so that negative pressure is generated in a negative pressure cavity, then the sputum in the respiratory tract of the patient is sucked into the sputum suction pipe through an L-shaped pipe and then collected into a sputum collecting barrel through a sputum outlet and a connector, and thus sputum suction operation is completed; and the problem that the auxiliary device for sputum adsorption is easy to slip off from the respiratory tract of the patient is solved,and the pain of the patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to an auxiliary device for sputum adsorption in elderly respiratory medicine. Background technique [0002] For critically ill patients, comatose patients, patients with tracheotomy and elderly patients with respiratory diseases, due to the inability to cough up sputum, sputum can easily block the respiratory tract and endanger life safety. one of the important ways. [0003] The current sputum suction device usually includes a sputum collection bottle, a sputum suction tube, a suction tube and a negative pressure structure. One end of the sputum suction tube and one end of the suction tube are all connected to the top of the sputum collection bottle. The free end of the tube is inserted into the sputum site, and the free end of the suction tube is connected to the negative pressure structure. The negative pressure structure works to generate negative pressure, and...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an auxiliary device for sputum adsorption in elderly respiratory medicine, which has the advantage of preventing the sputum suction tube from slipping, and solves the problem that the existing sputum suction device protrudes into the patient's respiratory tract to suck sputum. Because the diameter of the sputum suction tube is relatively small, the patient's respiratory tract is slippery due to a large amount of mucus, so the sputum suction tube is easy to slip off from the patient's respiratory tract, which not only brings pain to the patient but also adds trouble to the medical staff.
