Being hypo thermal is a potential threat for a trauma patient. Research has shown that administering a drip liquid at a lower temperature than the usual body temperature could have a negative influence on the total condition of the patient. You can imagine what the reaction will be for a person who suffers from hypo thermal when it gets a drip of 20C or even lower than that. The system developed by Geja makes it possible to adjust the drip correctly to the degree of the desired temperature.

The product contains a small light- weight case in which two bags of 500 ml or 1000 ml drip liquid has been placed in thermal units.
The thermal units have been attached to the case by of an elastic band.

An electric thermostat controls each thermal unit. With this electric thermostat one can adjust the desired temperature. It is also possible to adjust en secure the desired temperature in advance at delivery. One should take into account an accuracy of 1,5C. Temperatures can be read from a display. When the electronic thermostat is set at a certain temperature, one is warned by an acoustic alarm in case of a malfunction of the sensor and at an over temperature. If the temperature is still going up the current will be broken by means of a clixon and a red alarm light will start burning.

The case is attached to a 12 Volt-plug (or a 220Volt transformer) through the supplied linking cable. The consumption of current per thermal unit amounts to about 1 Ampere (20 Watt) for the 500 ml and 2 Ampere for the thermal unit of 1 litre. The case should be attached near a 12Volt connection (or a 220Volt transformer) by way of the supplied wall holder. This connection must be on a continuous electricity supply. The transparent front of the case enables it to read the specifications on the displays any time. The connection on the case is also equipped with a 5-Ampere fuse as a security device.


In use each thermal unit should be disconnected and taken from the case. To prevent the thermal unit from cooling down outside the case the unit is made of a special material. The drip can be injected while remaining in the thermal unit.
The drip will stay in its place by means of Velcro at the bottom of the thermal unit. At the top the thermal unit has a noose with which it can be suspended.

A pressure bag can surround the thermal unit in cases of forced administering of a drip. The thermal units can be cleaned domestically when they become filthy. We advise strongly not to use a washing machine and such-like.

A number of drip bags made by Baxter and Braun are tested at a temperature of 50 Centigrade. On the basis of these results, Geja advises to warm up the Sodium Chloride 0,9 % (Braun / Baxter) in the thermal units to a maximum of 14 days in its own wrapping at a temperature of 40 degrees Centigrade when using non- PVC bags. When this advice is followed correctly the drip liquid can be administered safely.

Generally it is advised not to inject medicine in the heated drip bag.
