Micro Vacuum Pump for Medical Industry

Micro vacuum pumps have extensive and critical applications in the medical field. Their small size, high efficiency, low noise, portability, and controllability make them suitable for a variety of medical devices. The following are several specific application scenarios of micro vacuum pumps in the medical field:

✅ 1. Negative Pressure Wound Therapy (NPWT)

Application principle:

The micro vacuum pump provides a continuous or intermittent negative pressure environment for the wound area, which promotes wound tissue regeneration and accelerates healing by sucking away exudate and bacteria.

Application equipment:

• Portable NPWT equipment
• Electric negative pressure wound therapy system for hospitals

Technical requirements:

Stable negative pressure range (usually -40 kPa to -120 kPa)

• Quiet operation (<50 dB)
• Support continuous work (>24 hours)
• The pump body must be corrosion-resistant (to prevent damage caused by liquid backflow)

✅ 2. Respiratory Therapy Devices

• Ventilators

Used to assist or replace spontaneous breathing, especially portable oil-free micro pumps are very popular during COVID-19.

Function: Suction gas or adjust pressure curve

Requirements: High dynamic response, oil-free and clean, low noise

• Suction Units

Used to remove secretions from the patient's mouth, trachea or bronchi.

Function: Rapidly establish negative pressure to extract liquid

Requirements: High flow rate (>15 L/min), controllable negative pressure (-50~ -80 kPa)

✅ 3. In vitro diagnostic equipment (IVD Devices)

Application areas:

• Microfluidic chip (Lab-on-a-chip)
• Blood gas analyzer, urine analyzer
• Chemieluminescence, enzyme-linked immunosorbent assay

Working method:

Use a micro vacuum pump to evacuate the reagent or sample chamber, transfer fluid, and achieve metering control

Technical requirements:

• High vacuum control accuracy (error <±2 kPa)
• Micro flow control (<1 L/min)
• High frequency start and stop (>100,000 cycle life)
• No pollution to biochemical media, no reflux

✅ 4. Laboratory automation equipment

Application examples:

• Automatic pipetting workstation
• Vacuum module of PCR instrument
• Blood separation, test tube vacuum packaging system

Features:

• Vacuuming for sample processing and prevention of cross contamination
• Requires high repeatability, chemical corrosion resistance, and sensitive control

✅ 5. Surgical and anesthesia auxiliary equipment

Typical equipment:

• Anesthetic gas recovery system (AGSS)
• Surgical drain, chest negative pressure drainage device
• Electric negative pressure suction device (used to aspirate blood or body fluids)

Required features:

• Quickly establish a stable vacuum (<3 seconds response)
• High negative pressure, high flow
• The pump body material must be sterilizable and resistant to drug corrosion

✅ 6. Dental and oral equipment

Typical uses:

• Saliva separator for dental workstations
• Suction of intraoperative fluids (blood, saliva, cleaning fluid)

Requirements:

• Ultra-low noise (<40 dB) to prevent affecting patient experience
• Long continuous working time
• Can be quickly stopped and started (used for intraoperative interruption of suction)

✅ 7. Body fluid sampling system and reagent distribution equipment

Application examples:

• Vacuum blood collection system (such as vacuum blood collection tube)
• Automatic urine sampling equipment
• Vaccine or drug filling machine

Principle:

• Micro vacuum pump is used to create negative pressure in a closed system to drive liquid flow or precise filling.
