AI Technical Summary

Technical Problem

The existing anti-suffocation products are unsafe and inconvenient to operate, and require help from others. The user's manual pulling force and speed affects the suction force and is difficult to operate on their own, especially for babies and other patients who need additional help.

Method used

A choke-proof instrument is designed, including a cylinder, suction nozzle, piston push rod, switch assembly and end cap assembly. The piston push rod is operated by keys to achieve one-button negative pressure suction. The built-in spring and locking plate structure ensure constant negative pressure and prevent accidental contact of the knob to improve safety.

Benefits of technology

It realizes convenient and safe operation of patients on their own in emergencies, constant negative pressure inhalation, avoids pressure fluctuations, and avoids secondary injuries. It is suitable for children and other self-operations.

Abstract

The invention discloses an anti-dysphagia instrument, and relates to the technical field of medical supplies. The dysphagia prevention instrument comprises a barrel, a suction nozzle, a piston push rod, a switch assembly and an end cover assembly, an inner cavity is formed in the barrel, an air inlet valve and an air outlet valve are arranged on the inner cavity, the suction nozzle is communicated with the air inlet valve, the piston push rod is movably arranged in the barrel, the piston push rod can seal the air outlet valve, and the switch assembly is connected with the switch assembly. The switch assembly comprises a key, a locking piece, a second spring and a fixing frame, the fixing frame is arranged at the upper end of the barrel, the second spring is installed on the inner side of the fixing frame and connected with one side of the locking piece, the key is arranged at the upper end of the barrel and connected with the other side of the locking piece, and the locking piece is clamped to the piston push rod under the elastic force of the second spring. The key is pressed to enable the locking piece to extrude the second spring, the locking piece is far away from the piston push rod, the end cover assembly is arranged at the upper end of the cylinder body, the end cover assembly is connected with the tail end of the piston push rod, and the end cover assembly moves along with the piston push rod.
