Embodiment Construction

[0027] figure 1 According to an embodiment of the present invention, a patient 1 is shown being administered intravenous (referred to herein as IV) fluid to be heated.

[0028] For example, the patient 1 may be a soldier on the battlefield receiving heated IV liquid. Alternatively, the patient may be located in a remote area without electricity or in an underdeveloped country. The IV device 2 for heating the liquid in the patient 1 before delivery into the patient 1 includes an IV bag 4, a liquid line 6, a power supply device 8 and a heating element 10. The liquid line 6 has a first end 12 connected close to the IV bag 4 and a second end 14 positioned relative to the first end 12. The second end 14 may be coupled to a catheter 16 having a needle therein for insertion into the blood vessel of the patient 1. For example, the blood vessel may be a vein or an artery.

[0029] The IV device 2 used to deliver the heated liquid to the patient 1 may be any standard liquid delivery syste...

Abstract

An apparatus for warming fluids includes a heating element having a resistance value that limits an amount of heat dissipated from the heating element to a threshold temperature value in response to a specific amount of electrical energy being applied to the heating element. A fluid carrying member may have the heating element coupled thereto to transfer heat from the heating element to a fluid within the fluid carrying member. A power supply may control a temperature of the fluid so as not to exceed the threshold temperature value by applying the specific amount of electrical energy to the heating element.

Description

Technical field [0001] This specification generally relates to the field of heating intravenous fluids, and more specifically, to methods and devices for heating intravenous fluids to a suitable temperature and not exceeding a safe temperature. Background technique [0002] Intravenous fluid delivery, such as drug delivery, is ubiquitous in healthcare practices worldwide. Intravenous fluid delivery is an important component in the ATLS (Advanced Trauma Life Support System) protocol used to treat traumatized patients. The ATLS protocol is designed to maximize the treatment within the first "golden hour" immediately after the trauma, thereby ensuring the best long-term results. Treatment during the "golden hour" usually includes intravenous fluid delivery, which usually takes place on the battlefield, in a hospital, or in an ambulance. [0003] During the treatment of hypothermia, heated IV fluid is generally required. The usual cause of hypothermia is surgery, which usually resul...
