Detailed introduction

Awake animal cages for rats and mice are mainly used to maintain free movement of rats and mice during microdialysis or long-term administration.

装置可以对清醒状态下的大鼠/小鼠进行长时间的微透析或给药实验。 The rat microdialysis cage / rat automatic drug delivery device can perform long-term microdialysis or drug delivery experiments on rats / mouses in the awake state. The rotation of the container counteracts the rotational force generated by the animal's activity, so that the catheter and the connection line are less tangled and twisted. With the behavior monitoring system, the activity of animals can also be monitored, so as to study the differences in the activities of animals before and after taking the medicine, which greatly improves the work efficiency of the experimental staff.

Awake mice and rats can keep rats and mice free during microdialysis or long-term administration. The patented Raturn device can perform long-term microdialysis experiments on small animals in the awake state. The rotation of the container counteracts the rotational force generated by the animal's activity, so that the catheter and the connection line are less tangled and twisted. With the behavior monitoring system, the activity of animals can also be monitored, so as to study the differences in the activities of animals before and after taking the medicine, which greatly improves the work efficiency of the experimental staff.
The Raturn device replaces the traditional liquid movable arm, ensures a continuous liquid path, ensures the continuity of the experiment, and greatly prolongs the service life of the awake movable arm. It is also possible to connect multiple pipelines from animals to complete experiments that previously required multiple animals to complete on one animal, and ensure the reliability of the experiment and the accuracy and stability of the experimental data.


Sampling Caging Systems
When sampling from awake, freely moving animals, one must ensure theanimals don't hurt themselves or damage your sampling lines. BASi offers two technologies to achieve this; the Raturn interactive caging system, and liquid swivels. The Raturn System is based on technology developed by BASi . However, as a company that prides itself on satisfying ourcustomers, we want to be sure to offer you the options you desire. Depending on your anticipated experimental goals, you may find it moreuseful to use one type of system over the other. The guide below isintended to help you select the system that best meets your needs.

The five-way swivel is a five-channel awake mobile device with low dead volume and small rotation torque, suitable for large and mouse experiments. It can meet the customer's requirements for simultaneous experiments such as single-site, dual-site microdialysis, and multi-point perfusion / body fluid collection in the awake state of rats. The channels are treated with special materials to prevent effects on neurotransmitters or the drugs being observed. The five-channel rotator includes a balancing arm to reduce vertical pressure above.  

Liquid Swivel-based Systems is composed of two small cylinders, which rely on the animal's drag to rotate. It requires the experimenter to carefully adjust the tightness of the two small cylinders. That is to resolve the contradiction between leakage and rotation. If the adjustment seal is tight, it can not leak liquid, but it is not easy to rotate and block the tube. If the adjustment seal is loose, the rotation is flexible, but it is easy to leak liquid. It is necessary to prevent easy leakage and adhesion between the two cylinders;
 
Liquid Swivel-based Systems
Swivel systems have been successfully been used for years byresearchers in pharma, universities, and CROs.
Swivels function by using concentric channels for each line thatgoes into or out of the subject. With each channel that is added to theswivel, the dead volume and the resistance to being turned by the animal increases.
Swivels contain internal seals which maintain the connection from the top of the swivel to the bottom (these seals require maintenance after each use of the swivel).
When using a swivel system, it is the swivel itself that turns to prevent twisting of the inlet and outlet lines.
A liquid swivel is satisfactory if:
You intend to use the system ONLY for a single type of sampling atone time (microdialysis or ultrafiltration or blood sampling)
There will only be one or two lines plumbed to / from the animal
The ability to upgrade, or add capability to your existing equipment is not important to you
You do not wish to use electrical lead lines
· You are not interested in collecting automated animal activity data
· You would like to be able to use a home-cage in your experimentalset-up. (Note: If your animal has a brain microdialysis probe or a guidecannula, we do not recommend sampling in a home cage with a descendingcage lid.)
