The YIDE 7A-23B electric suction apparatus is a high-capacity, heavy-duty surgical suction machine designed for continuous clinical use in operating rooms, ICUs, emergency departments, and general hospital wards. Powered by an oil-free self-lubricating piston pump, it delivers reliable high vacuum negative pressure and high flow suction performance without the contamination risks associated with oil-lubricated pumps. With dual 2500ml glass collection bottles, adjustable negative pressure, and low-noise operation, the 7A-23B is a trusted choice for hospital procurement teams and medical equipment distributors worldwide.

Key Features of the 7A-23B Electric Suction Apparatus

1. Oil-Free Piston Pump — Zero Contamination, Zero Daily Maintenance
The 7A-23B uses a fully oil-free, self-lubricating piston pump, eliminating oil mist pollution from the exhaust. Unlike traditional lubricated pump suction units, there is no need to add oil during daily operation, reducing maintenance workload and lowering the risk of cross-contamination in the surgical field. This makes it a preferred surgical suction apparatus for operating theatres where air quality is critical.
2. High Vacuum, High Flow — Built for Demanding Procedures
With a maximum negative pressure of ≥ 0.09 MPa (90 kPa / 680 mmHg) and a flow rate of ≥ 32 L/min, the 7A-23B is engineered for procedures requiring rapid fluid evacuation — including general surgery, ENT operations, obstetric and gynecological procedures, and emergency airway management. The adjustable negative pressure range (0.02–0.09 MPa) allows clinicians to dial in the precise suction level for each application, from gentle phlegm suction in ward patients to aggressive surgical field clearance in the OR.
3. Dual 2500ml Glass Collection Bottles
Two large-capacity 2500 ml glass collection jars provide a combined 5,000 ml total capacity, allowing extended surgical procedures without frequent interruptions for bottle emptying. The glass construction is heat-resistant and suitable for autoclave sterilization. An overflow protection valve automatically prevents liquid from entering the pump even when the canister is near capacity, protecting both the pump and the operator.
4. Foot Pedal + Manual Dual Control
The 7A-23B includes both a foot pedal switch and a manual switch, enabling hands-free activation during sterile procedures. Surgeons and scrub nurses can activate suction without breaking sterile technique — a critical feature in operating theatre environments.
5. Low Noise Operation — ≤ 60 dB(A)
At ≤ 60 dB(A), the 7A-23B operates quietly enough for sensitive clinical environments including post-operative wards, palliative care units, and overnight ward use. Noise reduction is achieved through the vibration-damped pump mounting and sealed ABS housing.
6. Compact Footprint, Easy Ward Mobility
Despite its heavy-duty capacity, the 7A-23B's compact dimensions (38 × 42 × 90 cm) and integrated carry design allow it to be moved easily between wards, fitted onto emergency trolleys, or positioned in space-limited operating rooms and ambulances. A rear storage compartment accommodates spare tubing, filters, and accessories.
7. Dual Voltage — Global Market Ready
Standard configuration supports both AC 220V/50Hz (EU, Asia, Africa, Middle East) and AC 110V/60Hz (Americas, Japan), making the 7A-23B suitable for export to virtually any market without modification.

Clinical Applications

The 7A-23B heavy-duty suction apparatus serves a broad spectrum of clinical settings:
Operating Room & Surgical Suction
As a dedicated surgical suction unit, the 7A-23B rapidly clears blood, irrigation fluid, pus, and tissue fragments from the operative field during general surgery, laparoscopy, ENT procedures, caesarean sections, and gynaecological operations. The high flow rate and large-capacity dual bottles ensure the surgical field remains unobstructed throughout extended procedures.
ICU & Critical Care
In intensive care units, the 7A-23B is used for continuous airway clearance — removing secretions, mucus, and vomit from patients who cannot clear their own airways. Its reliable negative pressure and overflow protection make it suitable for prolonged unattended operation at the bedside.
Emergency Rooms
For emergency airway management, the high-flow negative pressure suction quickly clears obstructions caused by blood, vomit, or secretions, reducing the risk of aspiration pneumonia in unconscious or seizing patients.
Respiratory Ward & Tracheostomy Care
For patients with chronic respiratory disease, coma, or post-operative tracheostomy, the 7A-23B provides controlled phlegm suction and sputum aspiration from the oral cavity, nasal passage, and upper airway. The adjustable pressure prevents mucosal trauma during routine suctioning.
ENT Clinics & Outpatient Surgical Centers
Compact enough for outpatient ENT suites, powerful enough for nasopharyngeal and laryngeal procedures, the 7A-23B is a versatile choice for specialty clinics needing a reliable hospital suction machine without the footprint of a full trolley system.
Dental Clinics & Oral Surgery
The 7A-23B can be used for high-volume saliva and fluid management during oral surgical procedures where a standard dental suction system may lack sufficient capacity or negative pressure.

How to Operate the 7A-23B Electric Suction Apparatus

1. Setup: Ensure both glass bottles are securely seated and caps are tightly fastened. Connect the patient-side suction catheter and bottle-side tubing.
2. Power: Connect to the appropriate mains supply (220V or 110V). Switch on the main power switch.
3. Pressure adjustment: Use the front-panel regulator to set the desired negative pressure within the 0.02–0.09 MPa range. Verify pressure on the gauge before patient contact.
4. Activation: Use the manual switch or foot pedal to activate suction. Begin with a lower pressure setting and increase as needed for the clinical procedure.
5. Monitoring: Monitor the fluid level in the glass bottles. Empty before reaching capacity to maintain consistent suction performance.
6. Shutdown: Switch off power. Release any residual vacuum before disconnecting tubing. Remove and clean/discard collection bottles per infection control protocol.
