Title: Improvements relating to syringe holders
Inventor: MARSHALL JEREMY
IPC: A61M5/32
Filed: 2002-04-29
Abstract: A syringe holder is designed to be thrown away after a single use with the syringe safely captive within. The holder has a barrel (5) into whose rear end a syringe (1) is entered until the rear flange (2) of the syringe seats in a socket (15). Then a gate (16) is hinged in a radial plane through a slot (14) in a thick flange (12) surrounding the socket (15) and snap fastens in a position obstructing rearward movement of the syringe (1). The syringe needle (3) projects forwardly of the barrel (5) and is shrouded by a sleeve (7) captive to the barrel and urged forwards by a spring (6).

Title: A process for storing enriched nematodes
Inventor: TANDLER AMOS
IPC: A23K1/18
Filed: 2002-06-04
Abstract: A process for preserving and storing nematodes having an increased feeding value for later use as needed in the feeding of aquaculture organisms. In this process, nematodes are enriched with an additive such as essential fatty acids, vaccines, hormones, immunostimulants, attractants, nutrients and pigments. Liposomes can serve as a medium for feeding the additives to the nematodes. The enriched nematodes are then desiccated by inducing a quiescent anhydrobiosis (dehydration) and stored for off-the-shell use as needed. When required for feeding, the desiccated enriched nematodes are rehydrated and fed to the aquaculture organisms.
