The Jianfan hemoperfutor user manual is an essential resource for medical professionals who operate hemoperfusion systems in clinical settings. Hemoperfusion is a blood purification technique widely used in emergency medicine, intensive care units, nephrology departments, and toxicology treatments. The Jianfan hemoperfutor is designed to remove toxins, inflammatory mediators, drugs, and metabolic waste from a patient’s bloodstream through adsorption.
Understanding the user manual is critical for ensuring patient safety, maximizing treatment effectiveness, and maintaining equipment reliability. This comprehensive guide breaks down the key elements of the Jianfan hemoperfutor user manual in a clear and structured way, helping clinicians, technicians, and biomedical staff confidently operate the device.
What Is the Jianfan Hemoperfutor?
The Jianfan hemoperfutor is a specialized medical device used in extracorporeal blood purification therapy. Unlike traditional dialysis, hemoperfusion relies on adsorption materials—often activated carbon or resin—to bind harmful substances directly from the blood.
Common Clinical Applications
- Drug and chemical poisoning
- Acute liver failure
- Sepsis and systemic inflammatory response
- Uremia and metabolic disorders
- Cytokine removal in critical care
The Jianfan hemoperfutor user manual outlines approved indications, contraindications, and operational protocols to ensure safe and effective usage.
Key Components Explained in the Jianfan Hemoperfutor User Manual
A thorough understanding of device components is the foundation of proper operation. The user manual typically identifies and describes the following parts:
1. Hemoperfusion Cartridge
This is the core adsorption unit where blood purification occurs. It contains adsorptive material designed to capture toxins and inflammatory molecules.
2. Blood Tubing Set
Medical-grade tubing connects the patient’s vascular access to the hemoperfutor and blood pump system.
3. Inlet and Outlet Ports
Clearly marked ports ensure correct blood flow direction, preventing reverse circulation.
4. Pressure Monitoring Interfaces
These ports allow continuous monitoring of arterial and venous pressure during therapy.
5. Protective Housing
Ensures sterility, stability, and physical protection of internal components.
Pre-Use Inspection and Preparation Guidelines
The Jianfan hemoperfutor user manual emphasizes strict pre-use checks to minimize complications and device failure.
Visual Inspection
- Check packaging integrity
- Confirm sterility indicators
- Inspect tubing for cracks or leaks
- Ensure cartridge is within expiration date
System Preparation
- Prime the hemoperfutor with sterile saline
- Remove all air bubbles from the system
- Verify correct connection to extracorporeal circulation equipment
- Confirm compatibility with blood pumps and monitoring systems
Failure to follow preparation steps may result in air embolism, clot formation, or reduced adsorption efficiency.
Step-by-Step Operating Instructions
The Jianfan hemoperfutor user manual provides a structured operating workflow. Below is a simplified overview for educational clarity.
Step 1: Patient Assessment
- Verify indication for hemoperfusion
- Assess coagulation status
- Confirm vascular access suitability
- Obtain informed consent
Step 2: Device Setup
- Mount the hemoperfutor vertically
- Connect arterial and venous lines correctly
- Secure all connections
- Confirm blood flow direction
Step 3: Initiating Blood Flow
- Start blood pump at a low flow rate
- Gradually increase according to prescription
- Monitor pressure readings continuously
Step 4: Anticoagulation Management
- Administer anticoagulant as prescribed
- Monitor clotting signs within the cartridge
- Adjust dosage based on patient response
Step 5: Treatment Monitoring
- Observe vital signs
- Monitor pressure differentials
- Check for alarms or abnormal resistance
- Ensure stable blood flow throughout the session
Recommended Treatment Parameters
The Jianfan hemoperfutor user manual specifies treatment parameters that should always be followed unless adjusted by a physician.
Typical Parameters Include:
- Blood flow rate: Based on patient size and condition
- Treatment duration: Usually 2–4 hours
- Pressure limits: Defined safe operating range
- Cartridge usage: Single-use only
Exceeding recommended limits may reduce adsorption capacity or increase patient risk.
Safety Precautions and Warnings
Patient safety is a primary focus of the Jianfan hemoperfutor user manual.
Important Safety Warnings
- Do not reuse single-use cartridges
- Never operate with damaged packaging
- Avoid excessive blood flow rates
- Discontinue therapy if clotting is observed
- Monitor for allergic or hypotensive reactions
Contraindications
- Severe bleeding disorders
- Uncontrolled hypotension
- Known hypersensitivity to cartridge materials
All contraindications must be reviewed before initiating therapy.
Common Alarms and Troubleshooting
The Jianfan hemoperfutor user manual includes troubleshooting guidance to address common issues during treatment.
High Pressure Alarm
Possible causes:
- Tubing kink
- Clot formation
- Excessive blood flow
Solution:
- Reduce flow rate
- Inspect tubing
- Replace cartridge if necessary
Low Flow Alarm
Possible causes:
- Vascular access issue
- Air bubble detection
- Pump malfunction
Solution:
- Reassess access
- Re-prime system
- Restart pump carefully
Post-Treatment Procedures
Proper shutdown and disposal procedures are critical for infection control and equipment longevity.
Ending the Session
- Gradually reduce blood flow
- Return blood to patient as per protocol
- Clamp lines securely
Disposal
- Dispose of cartridge as biohazard waste
- Follow institutional infection control policies
- Never attempt to clean or reuse the device
