The heating system is complemented by warm IV infusion and warm oxygen delivery to the victim.
Description
- 1. Field of the Invention
- This invention relates to a portable forced air warming apparatus for warming victims of hypothermia.
- Severe hypothermia is a surprisingly common occurrence in cold areas of the world. Hypothermia is considered to be severe when there is a significant risk of spontaneous ventricular fibrillation, which can result in death of the victim. The risk of ventricular fibrillation increases significantly when the victim's core or deep body temperature is below 28° C. At such low core temperatures, the victim should be handled carefully because of his/her unstable condition. A severe hypothermia victim who has been cooled rapidly, e.g. during immersion in water, is preferably rewarmed rapidly. A severe hypothermia victim who has been cooled slowly, e.g. by exposure to cold air, is preferably rewarmed slowly. In any event, it is imperative to stop heat loss and to initiate rewarming of victims of hypothermia as soon as possible to optimize the chances of survival. During rescue operations in remote areas, it may take several hours to transport casualties from the rescue site to a hospital for treatment.
- 2. Discussion of the Prior Art
- Warming apparatuses, some of which are portable, are disclosed by U.S. Pat. Nos. 5,300,101, which issued to S. D. Augustine et al on Apr. 5, 1994; 5,304,213, which issued to L. D. Berke et al on Apr. 19, 1994; 5,336,249, which issued to I. Mahawili on Aug. 9, 1994; 5,350,417, which issued to S. D. Augustine on Sep. 27, 1994 and 6,001,057, which issued to R. A. Bongiovanni et al on Dec. 14, 1999.
- The inventors have determined that when rewarming a hypothermia victim, it is preferable to heat the torso only while preventing heat loss from the extremities. Heating of the victim's limbs causes the return of cold blood to the torso which contributes to a core temperature drop that can decrease the chances of survival.
- Very few warming apparatuses are available in the marketplace, and those that do exist consist of heated blankets or bags for heating a victim's entire body and extremities, and devices for providing warm air for inhalation by the victim. A need exists for a system for eliminating heat loss and initiating rewarming of a hypothermia victim in the field.
- An object of the present invention is to meet the above need by providing a relatively simple, portable, forced air warming apparatus, which is easily transported to the field, and which can be used for controlled heating of a victim's body.
- Another object of the invention is to provide a portable warming apparatus which can be used to warm a victim's body only while preventing heat loss from the extremities.
- Yet another object of the invention is to provide a warming apparatus which can be used to effect controlled warming of the victim's head and neck which contributes to warming of the central nervous system, and helps a victim to regain normal respiratory and cardiovascular functions.
- In its simplest form, the invention relates to a portable warming apparatus for warming a hypothermia victim comprising a stretcher, said stretcher including a bottom wall, side walls and end walls contiguous with each other; a support extending between said side walls for supporting the body of a hypothermia victim, openings in said support permitting the circulation of warm air around the torso of the victim, a canopy for covering the torso of the victim and defining a heating chamber around the torso with said stretcher; at least one heating duct in said chamber for discharging warm air against the torso of the victim, whereby the warm air circulates through said openings around the torso; and a forced air heater for warming ambient air, and delivering the warm air to the heating duct.
- The invention is described below in greater detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:

- FIG. 10 is a perspective view of the shell of FIG. 7; and
- FIG. 11 is a perspective view of a leg bag used in the apparatus of FIGS.1 to 3.
- Referring to FIGS.1 to 3, the warming system of the present invention includes a housing generally indicated 1 defined by two
rectangular shells pin 6 on oneshell 2, and a notchedarm 7, which is pivotally mounted on theother shell 3 of the housing. In the fully open position (FIG. 2), thehousing shells tubular handles 8 are provided in the housing. The handles 8 (FIGS. 2 and 3 ) are slidably mounted insockets 9 in the corners of the outer free ends of theshells handles 8 are retained in the retracted, non-use positions bysmall latches 11, which are pivotally mounted on the ends of theshells handles 8. - The patient's head and neck are supported by a headrest generally indicated at12. The
headrest 12 is defined by aplatform 13 carrying acushion 14. Theplatform 13 is a thin, metal, generally L-shaped panel. Ashort arm 16 at one end of theplatform 13 includeskeyhole slots 17 for releasably mounting theplatform 13 onpins 18 extending outwardly from a plate 20 (FIGS. 4 and 5) on oneend 21 of theshell 2. The sides of the patient's head are covered by ahood 23, which is integral with thecushion 14. - The
shell 2 contains a plurality of spaced apart strips 24 (in this case nylon) for supporting the torso of a patient. Thestrips 24 extend transversely of the housing between the sides of theshell 2. The spaced apart strips 24 promote air flow around the patient's torso. However, other supports with openings permitting air circulation around the patient can be used. For example, thestrips 24 can be replaced by a perforated sheet or panel. - An inflatable, semicylindrical canopy generally indicated at25 is mounted on the open top of the
shell 2. Thecanopy 25 is defined by outer andinner shells arcuate end walls canopy 25 is stored in theshell 3 when the housing 1 is closed, i.e. not in use. After the housing 1 is opened, the canopy is removed and inflated using CO2 cartridges 31 carried by the canopy. In order to inflate thecanopy 25, anactuation cord 32 is pulled to open avalve 33 on one of thecartridges 31, admitting CO2 to the canopy through the valve. Excess pressure in thecanopy 25 is released usinghose 35 containing a one-way exhaust valve. Thecanopy 25 is attached toflanges 36 on the periphery of theshell 2 to surround the top and sides of the torso of the patient. The head and neck of the patient extend through a generallysemicircular notch 38 in oneend wall 29, and the hips and legs of the patient extend through asimilar notch 39 in the other end wall 30 (FIG. 8) of thecanopy 25.Notches 40 in the bottom side edges of thecanopy 25 receive the arms of the patient, so that the arms extend out of the canopy. - The arms of the patient are covered by
insulated sleeves 41. Eachsleeve 41 is attached to thecanopy 25 by aflap 42 sewn to thesleeve 41, straps 43 and buckles 44. With thebuckle 44 released, thesleeve 41 can be moved to accept a patient's arm. Once the arm is positioned in thesleeve 41, thebuckle 44 is closed to secure the arm in position against thecanopy 25. As best shown in FIG. 6, thesleeve 41 is tubular with aclosed end 46 and anopen end 47 for receiving a patient's arm. Azipper 49 extends longitudinally of thesleeve 41 permitting access to a patient's arm for connecting an IV line or for administering medicine. - With the
canopy 25 closed, the torso of the patient is warmed using a hot air system. Referring to FIG. 7, the hot air heating system includes ablower 51 mounted in theshell 3. Theblower 51 receives air via anopening 52 in one end of theshell 3. The air is circulated between theshells sheet 2 through an opening (not shown) flows through theopening 52 into theshell 3. Theopening 52 and the opening theshell 2 are closed when the apparatus is not in use, i.e. during storage or transport. The air discharged from theblower 51 passes through aduct 54 containing a pair of heating elements and a heat exchanger (illustrated schematically at 55), and then through aflexible tube 56 and an opening (not shown) in theshell 3. The warm air passes throughplastic connectors 57 at the ends of theshells shells - The warm air enters into one end of a
box 59 in one end of theshell 2. A manifold 60 (FIG. 9), defined by a plastic tube with a closed outer free end (not shown) extends out of thebox 59 across the end of theshell 2. A pair of plastic tubes orducts 62 extend out of the manifold 60 longitudinally of theshell 2. The closed outer ends of the ducts 60 are anchored to the end wall of theshell 2.Perforations 63 in the manifold 60 and theducts 62 discharge warm air into theshell 2 beneath thestrips 24. - A
flexible tube 64 extending out of the top of thebox 59 carries warm air to a manifold 66 (FIG. 8) extending transversely of one end of thecanopy 25.Ducts 67 carry air from the manifold 66, the length of the canopy. The free ends of the manifold 66 and of theducts 67 are closed.Perforations 68 in the manifold 66 and in theducts 67 discharge warm air into the top of the chamber defined by theshell 2 and thecanopy 25. - Referring again to FIG. 7, the interior of the
shell 3 is divided by apartition 70 into acompartment 71 containing theblower 51, theduct 54, the heaters andheat exchangers 55 and thetube 56, and astorage compartment 72 containing acontrol box 74. The controls (not shown) for theblower 51,heater 55 and the heater in thecushion 12 are located on a control panel 75 (FIG. 2) which forms the outer wall of thecontrol box 74 and is accessible from outside of the shell. The control box has preset controls for the speed of theblower 51 and the intensities of the heaters to provide different levels of heating power to the torso of a victim. Thestorage compartment 72 is used to store thecanopy 25 and the head supporting elements during storage or transporting. - When the apparatus is not in use, the
storage compartment 72 is closed by apanel 79, which is also used as a support for the legs of a patient during use of the apparatus. The cover/leg support panel 79 supports the legs of the patient in an inclined position. For such purpose, aleg 81 is connected to one end of thepanel 79 by apiano hinge 82. The bottom end of theleg 81 is maintained in position by aflange 84 extending around the two sides and the free end of theshell 3. - Referring to FIG. 11, an
insulated bag 85 is used to cover the legs of a patient. Thebag 85 is tubular with a closedbottom end 86 and an opentop end 87 for receiving the patient's legs. Alongitudinally extending zipper 89 facilitates insertion of the legs into the bag. A second zipper (not shown) extends across theclosed end 86 of thebag 85 to facilitate access to the feet of a patient, without opening thezipper 89. The bag 76 is made snug around the legs of a patient bystraps 90 and buckles 91. During storage or transporting of the apparatus, the bag 76 for the patient's legs remains on thepanel 79. - Thus, in its simplest form the apparatus described above includes a stretcher for supporting a hypothermia victim while warm air is circulated around the torso of the victim. The invention can be incorporated in a modified, commercially available stokes litter. Such a device would be admirably suited to certain search and rescue operations, e.g. ground search and rescue.
- It should also be noted that the apparatus described herein can be used for complete treatment of hypothermia victims in the field, including the administering of warm IV fluid to correct dehydration and improve circulation, and warm oxygen to assist in the oxygenation of tissues and decrease the risk of infection. An IV fluid bag and an O2 tank are carried in the stretcher beneath a victim. The containers are warmed by activating the heating system before placing a patient on the stretcher.
