RWD Osmotic Pumps

Animal fluids can pass through the sturdy semi-permeable membrane that makes up the osmotic pump. Animal fluids are absorbed by an internal high-pressure salt interlayer, which causes them to swell and crush the medication storage capsule. The stored liquid in the capsule can be continuously and precisely administered at a set rate to a particular tissue location.

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.

Locations of the Implanted Pump and the Medicine Pushed out

To distribute the medication, the pump can be surgically inserted into the peritoneal cavity or the back of the neck.

By affixing catheters or other devices, drug administration can even be for specific tissues like arteries, inner brain, spinal cord, lung, liver, etc.

Size of Pump

Models: 3 sizes, 100ul, 200ul, and 2ml. In-vivo testing has shown that the pump rate is steady.

Benefits of Material

To prevent immunological rejection following implantation in rats and mice, the osmotic pumps are made from biocompatible material. To ensure that mice and rats do not experience an inflammatory reaction, each pump is additionally disinfected by irradiation.

Advantages

Stable Pumping Rate

Predictable dosing and a reduction in experimental variables enable consistent and reproducible findings.

Reduced Stress Response to Mice and Rats

In contrast to the conventional repeated injections, continuous administration, without frequent animal handling, lowers the stress reaction and assures both the integrity of the experiment and the wellbeing of the animals.

Wide Application, Easy to Operate

Eliminating the requirement for routine injections on the weekends and at night. For systemic medication delivery, it can be inserted directly subcutaneously or intraperitoneally. It can also be attached to a catheter and used in other targeted tissues or organs, such as blood arteries, the brain, the liver, or other organs.
