Product Description

Liquid Injection Molding Medical Silicone Wound Drainage Bulb, Negative Pressure Wound Drainage Bulbs

Wound drainage bulbs are an essential component in the healing process of various wounds. These devices are designed to collect excess fluid and blood from a surgical site, allowing for better healing and reducing the chances of infection. Wound drainage bulbs are an important part of post-operative care. They help to prevent complications such as seromas, which are pockets of fluid that can develop after surgery. Seromas can cause pain, swelling, and delay healing. By removing excess fluid, wound drainage bulbs can help to reduce the risk of seromas and other complications.

Product Information

The manufacturing process of the wound drainage bulb is critical to ensure the effectiveness and safety for patients. Made from high-quality medical-grade silicone, the material is preferred due to its bio-compatibility, which means it is safe for use within the human body. The silicone is then molded into the desired shape using high precision liquid injection molding machine. The silicone injection molding process is critical to ensure that the drainage bulb has a smooth and uniform surface, which reduces the risk of tissue damage during use. Once the medical silicone has been molded, it is then cured to ensure that it retains its shape and properties. The curing process involves exposing the silicone to high temperatures for a specific period, which causes it to harden and become more durable. This step is critical to ensure that the drainage bulb can withstand the rigors of use without breaking or degrading.

Q: What is wound drainage bulb?

A: Wound drainage bulb is a small, portable device that collects excess fluids from surgical wounds. It consists of a silicone bulb with a drainage tube attached to it.

Q: How does a wound drainage bulb work?

A: The drainage tube is inserted into the surgical wound, and the bulb is squeezed to create a vacuum that pulls excess fluids out of the wound and into the bulb.

Q: What are the benefits of using a wound drainage bulb?

A: Using a wound drainage bulb can help reduce the risk of infection and promote faster healing by removing excess fluids from the surgical site.

Q: Are wound drainage bulbs reusable?

A: No, wound drainage bulbs are designed for single-use only and should be disposed of after each use.

Q: How are wound drainage bulbs manufactured?

A: Wound drainage bulbs are typically made from medical-grade silicone or PVC plastic using silicone injection molding or blow molding techniques.

Q: How often should a wound drainage bulb be emptied?

A: Wound drainage bulbs should be emptied when they are approximately half full to prevent overfilling and potential leakage.
