It is manufactured by Keling Medical (Jiangsu Keling Medical Appliances Co., Ltd.) for hospitals, clinics and household first-aid use. ## Quick Facts - The Keling DFX-23A-I is a portable electric sputum suction machine for clearing sputum and thick secretions from patients in hospitals and for first aid at home. - Free air flow of the DFX-23A-I is ≥18 L/min, with an adjustable negative pressure range of 0.013–0.08 MPa. - Liquid vessel capacity is 1×1000 ml medical-grade plastic, with a macromolecule suction bottle that is easy to disinfect and clean. - Noise level is ≤55 dB and input power is 150 VA; power supply is 220 V ±10% 50 Hz ±2%. - The one-piece molded ABS housing provides a durable, compact and lightweight form factor suited to bedside and portable use. - A built-in overflow protection device prevents fluid ingress into the pump assembly, protecting the maintenance-free oil-free piston pump. ## Overview The DFX-23A-I portable electric sputum suction machine is designed for efficient, low-noise aspiration of sputum and other thick secretions from patients' airways in hospitals and clinics, and for emergency first-aid use in household settings. Its oil-free piston pump requires no lubrication maintenance, and the compact ABS one-piece housing keeps the unit lightweight and easy to carry between beds or to different care locations. Free air flow of ≥18 L/min and an adjustable negative pressure range of 0.013–0.08 MPa give clinicians sufficient suction strength to clear moderate secretion volumes efficiently. The macromolecule (medical-grade polymer) suction bottle is engineered for straightforward disinfection and cleaning between uses, reducing cross-contamination risk. An integrated overflow protection mechanism automatically prevents collected fluid from reaching the pump interior even if the bottle approaches full capacity, protecting the pump from damage and reducing maintenance requirements. The low-noise motor design — ≤55 dB at working conditions — keeps bedside environments quieter for patients. A front-panel vacuum gauge and simple ON/OFF and VACUUM controls make the unit intuitive to operate without specialist training, supporting deployment across wards, emergency rooms and household care environments alike. ## Key Features - **≥18 L/min free air flow** — sufficient suction rate for effective clearance of sputum and thick secretions from patients' airways. - **0.013–0.08 MPa negative pressure range** — adjustable vacuum strength to match the clinical requirements of different secretion types and patient conditions. - **One-piece molded ABS housing** — compact, durable and lightweight construction suited to bedside and portable field use. - **Macromolecule suction bottle** — 1×1000 ml medical-grade plastic bottle is easy to disinfect and clean between patients, reducing infection risk. - **Maintenance-free oil-free piston pump** — requires no lubrication servicing, reducing downtime and total cost of ownership. - **Built-in overflow protection** — prevents secretion fluid from entering the pump assembly if the bottle reaches capacity, protecting pump integrity. - **≤55 dB low-noise operation** — quiet motor design maintains a comfortable bedside environment during extended suctioning procedures. ## Technical Specifications | Parameter | Value | |---|---| | Model | DFX-23A-I | | Product type | Electric sputum suction machine | | Power supply | 220 V ±10% 50 Hz ±2% | | Free air flow | ≥18 L/min | | Negative pressure range | 0.013–0.08 MPa | | Noise level | ≤55 dB | | Input power | 150 VA | | Liquid vessel | 1×1000 ml (medical-grade plastic) | *Specifications are subject to change; dimensional tolerances may apply.
