Briefly, a kinkless infusion set has a setting control that engages a curved or helical cannula to simultaneously rotate the helical cannula as the helical cannula is moved toward a patients skin and then under the patient's skin to position the curved or helical cannula to a desired depth and position. In one example, the helical cannula is set between 3 mm and 5 mm under the patient's skin. Also, the curved or helical cannula may have side ports to allow medicine to be presented over a larger area for more effective therapeutic treatment. In some constructions the patient rotates the setting control, and in other cases the patient may push, pull or translate the setting control.

Kinkless infusion set for medical use

A guide for supporting a device in a flow of coolant includes a deflector for modifying the coolant flow. The guide include apertures so that the coolant can flow over both the upper and lower faces of a device, for example a printed circuit board

Flow guide

A cooling apparatus for cooling an electrical device using a flow of coolant comprises a cooling unit . The cooling unit is in contact with the device and includes a channel for transporting the coolant past the device . In a preferred embodiment, the sectional area of the channel decreases between the inlet and the outlet of the channel . The velocity of the flow of coolant past the device can be modified, thus improving the efficiency of cooling.

Cooling devices

Cooling apparatus is used to cool equipment, for example electrical equipment, using a fan. In an embodiment described, the cooling apparatus comprises a duct for communication with the fan and for transporting air past the equipment. The duct may include a diffuser for improving the air flow in the duct.
