Intermittent Infusion
Home Cage Package

MED-125-CT
Home Cage Infusion Flush Test Package for Rat

This is our turnkey system for doing intermittent home cage infusions in catheterized rats. Permanently attached tethers have been found to remain trouble free for longer periods of time when given periodic infusions with saline in the home cage. Up to three individually housed rats can be infused from a single syringe pump loaded with three syringes. The MED-125CT package includes six PHM-125B plastic home cages with ad lib food and liquid receptacles. Three of these are used to hold animals at any point in time, while the additional three cages serve as backups to have on hand for routine cage changes. The top lid of the PHM-125B home cage features a slot and hole allowing the tether system to exit the cage, and the lid is held on the cage using slots and screws. This mechanism allows secure housing of the animal, while facilitating removal with the leash attached to the animal when experiment time comes. The PHM-110-SAI drug delivery arm assembly is a counter balance to support the swivel and leash assembly. We have also included three PHM-119A-23 quick disconnect drug delivery assemblies. The PHM-102-A Triple Infusion Pump with Expanded Cycling Timer Options infuses up to three animals at the same time. A pair of two digit thumb-wheel switches are used to set a cycle time from 1 to 99 minutes and an infusion time from 1 to 99 seconds. A setting of 60 and 10, for example, will produce a ten second infusion at one hour intervals. Other features include a flush push button, test mode, single injection mode, and indicator lights that identify cycle activation and infusion activation.

Interface, computers and software are sold separately.
