Single-Use Stopcock
Intended Use
This device is intended for single use of clinical infusion therapy, for changing the infusion direction, extending the infusion pipeline and/or pressure monitoring. The use time in clinical for Pressure Stopcock with Extension Tube shall be no more than 7 days, the other variants shall be not more than 24 hours.
Order Information
The stopcock with extension tube is available in Normal and Pressure type; the stopcock manifold is available in form of 2 or 3 manifolds.
Warning
1. The use of the device must comply with the relevant operating standards and regulations of the medical department, and is limited to trained medical personnel only;
2. Please check the single package before use. Must not use if the package is opened or damaged;
3. All channels should be kept clean and sterile;
4. The shelf life of this device is 3 years.
5. The stopcock with pressure extension tube can be connected to the pressure infusion set to extend the pressure monitoring pipeline. Other models and specifications are prohibited from being used in high-pressure injection systems.
6. This device is only intended for one-time use, and repeated use increases the risk of cross infection. Strict aseptic operation is required during use. Dispose of waste products according to hospital or environmental protection department regulation after use.
7. When there is blockage or leakage during the correct use of the device, medical personnel should promptly stop treatment and replace the device for the patient.
8. Before starting the infusion of the device, it is necessary to confirm the tightness of the connection.
9. The use of infusion sets without threaded interfaces can easily lead to lose connections, leakage, and other situations. It is recommended to use infusion sets with threaded interfaces.
10. After tight connection, do not turn the stopcock counterclockwise before use to prevent accidental loosening or detachment, which may cause liquid leakage.
11. If the device is tightened too tightly, there may be a tendency for cracks to appear under the contact of infusion solution or medication.
12. When using the product in oncology, anesthesia, and other places, close attention should be paid to whether the medicine poses a risk of damage to the device.
13. Sediments of incompatible substances in the blood or coagulation and physicochemical properties of the connecting site may lead to the risk of cracking and difficult disassembly of the device.
14. Due to the sudden change in temperature required for treatment, there is a risk of device cracking and difficulty in disassembly.
15. To avoid the risk of device cracking, leakage, and loosening during use, multiple devices should be avoided from being used in series. Suggest using manifolds one.
16. The device is prone to damage under the erosion of medicine such as cyclosporine, nimodipine, etoposide, propofol, cyclophosphamide, lipids, and sodium phenytoin.
17. The stopcock should be properly fixed during use, especially for children, the elderly, irritable and emotionally unstable patients. Patrol should be strengthened, and if necessary, auxiliary methods should be used to fix it to avoid loosening and leakage during use.
18. To ensure stable operation and avoid problems such as looseness or difficulty in twisting, please hold the device with both hands for operation.
No absolute contraindication.
FAQs – Disposable Stopcock
1. Q: What types of stopcocks are available?
A: Three main types:
Three-way stopcock
Stopcock with extension tube (Normal or Pressure type)
Stopcock manifolds (2 or 3 manifolds)
Covers infusion direction change, extension, and pressure monitoring needs.
2. Q: How long can I use each type?
A:
Stopcock with Pressure Extension Tube: ≤ 7 days
All other variants: ≤ 24 hours
Strictly follow – exceeding limits increases infection/device failure risk.
3. Q: Can I use any stopcock for high-pressure injection?
A: No. Only stopcock with pressure extension tube is designed for connection to pressure infusion sets. Other models are prohibited for high-pressure systems. Check specification before use.
4. Q: What materials are used? Are they safe?
A: Medical-grade polycarbonate (PC), polyurethane (PU), and polyethylene (PE). EO sterilized, non-pyrogenic, latex-free. Biocompatible and clinically proven.
5. Q: Can I reuse this device?
A: Absolutely not. Strictly single-use only. Reuse increases cross-infection risk, device failure, and patient harm. Dispose per hospital or local regulations.
6. Q: What should I do if blockage or leakage occurs during use?
A: Stop treatment immediately and replace the device. Do not attempt to repair or continue use. Patient safety first.
7. Q: Why do you recommend using infusion sets with threaded interfaces?
A: Non-threaded Luer connections are prone to loosening, leakage, and accidental disconnection. Threaded Luer-lock provides secure, leak-proof connection – critical for patient safety.
8. Q: Can I turn the stopcock counterclockwise after tightening?
A: Do not turn counterclockwise before use. Accidental loosening may cause leakage, disconnection, or air embolism. Always operate with both hands for stable control.
9. Q: Is this product compatible with all medications?
A: Use with caution for certain drugs. Risk of device cracking/damage reported with:
Cyclosporine
Nimodipine
Etoposide
Propofol
Cyclophosphamide
Lipids
Sodium phenytoin
Evaluate compatibility before clinical use.
10. Q: Can I connect multiple stopcocks in series?
A: Avoid multiple devices in series – increases risk of cracking, leakage, and loosening. Use manifolds instead for cleaner, safer multi-line management.
11. Q: How should I fix the stopcock during use?
A: Properly secure the device, especially for:
Children
Elderly
Irritable/emotionally unstable patients
Strengthen patrol and use auxiliary fixation methods if needed. Prevents accidental loosening and leakage.
12. Q: What are the contraindications?
A: No absolute contraindications. However, do not use if:
Package opened/damaged
Expired (shelf life: 3 years)
Used beyond recommended duration
Incompatible with high-pressure systems (except pressure type)
13. Q: Is this product CE certified?
A: Yes. Manufactured under ISO 13485, CE marked, compliant with EU MDR. Sterile, EO sterilized. Full documentation available for tenders.
14. Q: Do you offer OEM or private labeling?
A: Yes. OEM/private label available. Custom packaging, labeling, and manifold configurations. MOQ applies – contact sales team.
15. Q: How should I store this product?
A: Store in original packaging, cool, dry place. Do not use if package damaged or expired. Sterile unless opened.
