What are the main components of a disposable flush suction device?

The disposable flush suction device is mainly composed of the following key components:

Receiver: As one of the core components of the flush suction device, the receiver is responsible for connecting other components to form a complete flush suction system. It is made of corrosion-resistant and pressure-resistant materials to ensure the smooth and safe flow of flushing fluid and waste liquid. The design of the receiver needs to take into account compatibility with catheters, valves and other components to ensure the stability and reliability of the entire system.

Catheter: The catheter is the channel for the flow of rinsing fluid and waste liquid, and its material needs to have good flexibility and abrasion resistance in order to adapt to a variety of bending and pulling in the surgical process. Common catheter materials include medical grade PVC and other plastics. Catheters have a smooth inner wall to minimize fluid resistance, while their outer diameter is moderate to facilitate the surgeon's manipulation during the procedure.

Flushing Valve and Suction Valve: These two valves control the flow of flushing fluid and waste fluid, respectively. The flushing valve is used to open or close the passage of flushing fluid to ensure that the flushing fluid can enter the surgical site as needed; while the suction valve controls the suction of waste fluid to help the surgeon remove waste fluid and residues from the surgical area in a timely manner. The valves are designed to ensure easy operation and reliable sealing to avoid leakage and misuse.

Valve body: The valve body is the component that installs the flushing valve and suction valve, and plays the role of supporting and fixing the valve. The material of the valve body needs to be matched with the receiver and conduit to ensure the stability and compatibility of the whole system. At the same time, the design of the valve body needs to be considered easy to clean and disinfect to meet the requirements of medical use.

Stainless steel flush suction tube: Stainless steel flush suction tube is another core component of the flush suction device, which is responsible for delivering the flushing fluid to the surgical site and suctioning out the waste fluid and residue. This component is made of high-quality stainless steel with excellent corrosion and abrasion resistance, which ensures stability and reliability during the surgical process. The Stainless Steel Flush Suction Tube has a smooth, rounded design without a sharp piercing tip end to avoid unnecessary damage to patient tissue. Its smooth inner wall reduces fluid resistance and improves the efficiency of flushing and suctioning.

Clamps: Clamps are used to secure the catheter and prevent it from moving or falling out during the procedure. The clamps are designed to be easy to maneuver and securely fastened so that the surgeon can readily adjust the position and angle of the catheter during the procedure.

Suction connector: The suction connector is the component that connects the suction tube to the negative pressure suction system. It usually has a standardized interface design to allow compatibility with different types of negative pressure suction systems. The suction connection is designed to ensure a reliable seal to avoid leakage and loss of negative pressure.

In addition, depending on the specific design and functional requirements, a disposable flush suction unit may also include other components such as a tee tube (for connecting the passageways for rinsing and waste fluids), a back cover (to close the back end of the flush suction unit), seals (to ensure a tight seal between the various components), etc.

Overall, Donho's various components of a disposable irrigation and suction device work together to form a complete irrigation and suction system that provides the necessary irrigation and suction functions for surgery. Strict adherence to relevant medical standards and specifications is required during manufacture and use to ensure the safety and effectiveness of the product.
