The disclosed techniques relate to an apparatus including: a pump body, an occlusion bed; and a rotor. The rotor includes: a shaft body; a roller body slidably mounted to the shaft body; and a lock mechanism selectively positioned between a first position and a second position. In the first position, the lock mechanism engages with the roller body to lock the roller body at a first roller body position relative to the shaft body where the one or more rollers can compress tubing disposed in the apparatus against the occlusion bed with a first level of compression. In the second position, the lock mechanism disengages the roller body so the roller body can slide along the track relative to the shaft body to a second roller body position configured to cause decreased or no compression of the tubing against the occlusion bed by the one or more rollers.

Peristaltic pump offset rotor assembly

The invention provides improved modular gun stocks and their methods of manufacture. Advantageously, gun stocks of the invention require fewer parts than conventional gun stocks. The lower stock supports of the improved modular gun stocks can be removed and replaced in multiple ways so that a variety of gun stocks can be created as desired. The invention also eliminates the undesirable rattling noise that modular gun stocks often have after assembly.
