Osmotic Pumps

Overview

The osmotic pump consists of a robust semi-permeable membrane that allows animals’ fluids to pass through. Built-in high-pressure salt interlayer, which absorbs animal fluids, causing them to expand and squeeze the drug storage capsule. The stored liquid in the capsule can be delivered to specific tissue area continuously and accurately at a constant rate.

Applications

• Cardiovascular disease model;
• Addiction Research;
• Emotion-based research;
• Medication research for diabetes and other metabolic diseases;
• Pain, injury, and other therapeutic drug infusions;
• Cancer Drug Screening;

Positions of the implanted pump and the drug pumped out

The pump can be implanted directly into the peritoneal cavity or the back of the neck to deliver the drug.
Drug delivery can be even for specific tissues, such as vessels, inner brain, spinal cord, lung, liver etc., just by attaching catheters or other accessories.

Size of Pump

Models: 3 sizes, 100ul, 200ul, and 2ml. The pump rate is stable through in-vivo testing.

Benefits of material

Made by biocompatible material to avoid immune rejection after implantation in rats and mice. Each pump is also sterilized by irradiation to ensure no inflammatory reaction in mice and rats.

Advantages

Stable Pumping Rate

Predictable dosing and minimizes experimental variables to ensure reproducible and consistent results.

Reduced Stress Response to Mice and Rats

Different from the traditional multiple injections, it reduces the stress response by continuous administration, without frequent animal handling, that ensures the experimental results and that animal welfare is guaranteed.

Wide Application, Easy to Operate

Reducing the need for regular injections at night and on weekends. It can be directly subcutaneously or intraperitoneally embedded for systemic drug delivery, or connected to a catheter for use in other specific tissues or organs such as blood vessels, brain, liver, etc.
