Abstract

The invention discloses a sputum excretion device for a critical patient in the neurosurgery department, and the device comprises a sputum collection bottle with an opening in the top; the sputum collection bottle is sleeved with a bottle cap in a threaded mode, the right side of the sputum collection bottle is fixedly connected with a U-shaped handle, a sputum suction hose is arranged above the bottle cap, and an air pump is fixedly installed on the right side of the top of the bottle cap; the bottle cap is provided with a two-way quick cut-off mechanism and a quick-locking type opening sputum suction mechanism matched with the two-way quick cut-off mechanism. The design is reasonable, the two-way plugging can be automatically removed when the air extracting pump is started, the air inlet end and the sputum suction hose can be rapidly plugged in the two directions when the air extracting pump is stopped, the phenomenon that a person forgets to plug after use can be effectively avoided in the mode that plugging and plugging removing are linked with starting and stopping of the air extracting pump, and the risk that sputum flows out or into the sucking pump due to accidents such as toppling and the like after sputum suction is completed is reduced, and use is facilitated.

Description

technical field

[0001] The invention relates to the technical field of expectoration equipment, in particular to an expectoration device for critically ill patients in neurosurgery. Background technique

[0002] It is a common and important defensive mechanism when coughing and expectoration. Some neurosurgical patients with severe neurosurgery cannot complete expectoration independently. Most of the sputum devices use sputum suction devices, which mostly use the principle of negative pressure suction to achieve sputum suction. Most of them are composed of sputum collection bottles, sputum suction hoses and suction pumps. Collection device.

[0003] The existing sputum removal device for critically ill patients in neurosurgery is inconvenient to quickly block the suction end of the suction pump and the sputum suction hose in two directions when the suction pump is stopped after the sputum suction work is completed; it is easy to place it after use or On the way to the tras...
