The soft inner layer (20) is made of micro fiber in order to release the heat onto the skin of the patient, the outer layer (40) is impermeable for the heat, the central layer (30) is made of a rigid material in order to avoid an interruption of the heat circulation by the blanket (100) being partially squeezed flat by the weight of the patient's body.

Description

The present invention relates to a thermal blanket, in particular thermal underlay having

• - at least one connection for the supply of warm air;
• - At least one of the bodies to be heated by means of the thermal blanket by facing, designed for the warm air permeable interior layer or inner layer; and
• - At least one of the bodies to be heated by means of the thermal blanket by averted, essentially impermeable to warm air trained outer layer or outer layer.

Thermal blankets of the type mentioned at the outset (cf. document DE 201 03 432 U1) basically serve to control the temperature of one on the heat dec ke stored and / or covered by the thermal blanket by Warm air is supplied. Such thermal blankets are found in particular but not exclusively in the medical field Prevent loss of measurement of people to be treated, the same constant heat regulation disrupted or temporarily overridden sets is.

The thermal blanket is placed under and / or over the patient's body tin or of the patient, and by at least one feed Hose-fed warm air spreads across the body the inside of the blanket to warm the body men. With regard to the relevant prior art, this Relationship additionally to the thermal blanket according to the pressure document US 5 891 187 noted.

In the past, with regard to the aforementioned Wärmedec However, the type of use in which the Warming blanket in the form of a to be placed under the body of a person is formed with warm air to be flooded underlay and the used accordingly. In this form of use there is Danger of lying on the person as a thermal pad trained heat blanket the through intended for the warm air flow lines are compressed and blocked in extreme cases. Otherwise, this danger is insufficient or even completely absent not only supply warm air to certain parts of the body Given to people with high body weight, but also in particular Infants or toddlers who are in proportion to their other bodies a relatively large contact area on the thermal blanket  or have thermal underlay.

In this context, in relation to operations in particular, the means to penetrate in the medical and especially in the surgical field the need for continuous and "gentle" heat supply to human beings Chen body, because the usually required during an operation Partial or full anesthesia par basic body functions partially or completely suspended for the duration of the anesthetic, so that the danger of dangerous cooling or hypothermia of the Body is very high.

This is what a patient is like, especially during an operation very sensitive to heat, because the anesthetized person is no longer in the Able to regulate their temperature through the skin; this means that at large temperature release through the skin no change in the skin and consequently, no reheating can take place.

In addition, the overall body temperature is also sensitive; if namely, the patient is hypothermic, this draws a lot much longer residence time in the intensive care unit until the body temperature is optimally set again. In addition, patients and patients who need hypothermia need a lot of warmth rend normothermic patients only with intake of body temperature pointing air must be reheated so that no tempera door waste arises.

Based on the disadvantages and shortcomings set out above opportunities and in consideration of the outlined state of the art in the case of thermal blankets, especially thermal underlays, this is the case ing invention the task of a thermal blanket, in particular re heat pad, of the type mentioned so that the Warm air in any case continuously under the body to be warmed  a person can be passed through, so that on the warmth blanket, especially thermal underlay, supporting body parts under each conditions are reliably warmed.

This task is covered by a thermal blanket, especially a thermal blanket location, solved with the features specified in claim 1. advantageous Refinements and appropriate further developments of the present Er invention are characterized in the subclaims.

According to the teaching of the present invention is therefore between the Body-facing inner air permeable to the warm air ge or inner layer and facing away from the body, for the warm air essentially impermeable outer layer or outer layer at least one intermediate layer or intermediate layer arranged.

In other words, this means that the interior space or "In nenraum "of the heat blanket, in particular the heat pad, with a Material is filled that not only ensures warm air passage, son also a pressure-relieving bedding of anesthetized patients and patients, especially babies and toddlers stet.

The thermal blanket according to the present invention is therefore with your inner layer or inner layer facing the body underneath these Body and / or placed on this body and does not isolate it only, but warms it convectively, that is, with outflowing Warm air; it is this convective heat supply that cools down cooling or hypothermia also of a body to be operated on reliably prevented.

By this measure, the in Operating room prevailing room temperature can be significantly reduced  because, according to the teaching of the present invention, the warm air by means of the thermal blanket, in particular thermal underlay, in individuali definable and specific form of that necessary during the operation at least partially undressed to be operated on. The latter especially the surgical person involved in the operation nal appreciate this, for example, because of X-rays to be taken during the operation anyway heavy, because lead-shortened and therefore sweaty work clothes wear.

The expert in the field of thermal blankets, especially the Thermal documents, for example a university engineer on the Field of textile technology with special knowledge in the area of heat melehre, is further with respect to the teaching of the present inven dung appreciate that the other two layers or layers (namely the inner layer or inner layer as well as the outer layer or Au outer layer) by arranging the intermediate layer or intermediate layer cannot be compressed to the extent that a through leave, a passage, a flow and / or a transport of the Warm air would no longer allow (the side parts of the body who the one that also flows out of the inner layer or inner layer Warm air warmed).

If the present thermal blanket, in particular a thermal underlay, is to be developed in a particularly inventive manner, the following structure is recommended:

• At least one microfiber layer as the inner layer or inner layer, which is permeable to air, that is to say permeable to warm air det is;
• - as an intermediate layer or intermediate layer at least one spacer / Storage fabric or knitted fabric, in particular at least one Polyester woven or knitted fabric, for letting through, for letting through  to flow and / or to transport the warm air; and
• - as outer layer or outer layer at least one textile layer, The air-impermeable, that means impermeable for the warm air is formed.

Through the appropriate choice of a particularly advantageous type of microfibre on the inner layer or inner layer of the heat facing the body medecke, especially the heat pad, it is possible to fix use the same adhesive strips that are skin-friendly on the one hand and on the other hand no adhesive residues on the microfiber material leave.

According to a preferred development of the present invention the liner or intermediate layer is at least a plastic fabric or knitted fabric that is elastic enough on the one hand, order with regard to the deformation properties under compressive stress to guarantee comfortable and pressure-relieving lying, and that on the other hand, it is so rigid that it is only conditional, that is, for example can compress by about ten percent, so that a flow through is guaranteed with warm air.

According to an advantageous embodiment of the present invention is the thermal blanket on its outer layer facing away from the body or Outer layer heat-reflective; this can in particular by a white coloring of the outer layer or the outer layer hen.

Such a design has the advantage that the outside Surface warmed less than usual in the operating area green materials. This in turn leads to the adhesive layers of Adhesive strips with which the thermal blanket, in particular thermal underlay  often on an operating table or on the body delden person is not easily attached to the heat blanket remain so that a later disinfection and / or cleaning the heat medecke is better possible.

According to various alternative embodiments of the present invention which are alternative to one another or can be combined with one another, the thermal blanket, in particular a thermal underlay, has

• - At least one head area or at least one head part and / or
• - At least one arm area or at least one arm part and / or
• - At least one upper body area or at least one upper body perteil and / or
• - At least one lower body area or at least one lower body perteil and / or
• - At least one leg area or at least one leg part and / or
• - at least one side part and / or
• - at least one pocket part

on.

These parts allow an optimal adjustment of the heat blanket, especially especially the thermal pad, to the physical conditions of the pa patient or the patient, be it an infant, a toddler, an adolescent growing or an adult; for example, individual ar me and / or individual legs inserted into pocket-like parts become; whole parts of the body can also be covered.

According to an expedient embodiment, the thermal blanket comprises in particular thermal underlay, at least one head area, with the head and / or neck of someone covered by the thermal blanket Person can be brought in contact around the head and / or neck to be heated by the supplied warm air.  

In contrast to conventional thermal blankets, the thermal underlay leaves ge according to the present invention thus the head area and / or not open the neck area of a patient, but rather also includes these areas in the insulation and heat supply. This can significantly improve the temperature control properties of the present thermal blanket can be achieved. So can For example, in the case of an anesthetized person, the heat loss of the Body by up to about twenty percent over conventional ones Thermal blankets can be reduced.

There are various options for the design of the head area available. According to a preferred variant, the Head area at least two stripes from an upper body area, especially from a chest / back area, the thermal blanket, especially special of the thermal pad, go out and the head of a closed covered person can be arranged in a comprehensive and / or supportive manner can.

The stripes coming from the upper body area of the thermal blanket can if the upper body area - depending on the storage of the For example during a surgical procedure - on the chest and / or on the back of a patient duck is arranged lying, especially along the neck of the patient tin or the patient and around the head. To this In this way, the strips protect and guide the corresponding parts of the body to this warm air. In this context it is advantageous that the Stripes are flexible and therefore very precise to the respective body perform or adapt to the respective head posture.

The strips are preferably all over or at least partially for Warm air permeable. In the permeable areas, the supplied Escape warm air and thereby heat the adjacent  Body parts worry.

Because the head area as well as the neck area in contrast to the upper body or trunk area are not completely covered can, the strips are conveniently not only on the immediate bar air-permeable side trained, but by arching the inside at least partially also in the outside are sufficient so that a warming due to air leakage from these areas from the head and neck.

The strips described above preferably have connecting means in their respective end areas, by means of which the ends of the strips can be fixed to one another. The connecting means can be essential to the invention

• - As at least one Velcro connection and / or
• - as at least one button connection,
  in particular as at least one push-button connection, and / or
• - As at least one lacing connection

be designed.

Due to the connecting means arranged at the ends, the two Stripes connected to each other after laying around the head to form a loop of fixed length, its configuration and Maintains stable position.

Preferably, the connecting means at the ends of the strips are like this arranged or set up that the connecting means a connection allow the end areas of the strips at different angles; this allows the strips in different configurations and on ver to put different ways around your head and still for one to ensure secure detachable connection of the end regions.  

According to another preferred development of the present invention The head area can have position-variable covers to direct the exit of the warm air and in the covered areas to suppress chen. The covers can be made, for example at least one air-impermeable material and / or from at least an air-impermeable fabric.

Furthermore, the covers in the head area can correspond to Appropriate fastening means, for example Velcro fasteners or the like, be attached in the desired position. If about the head area is formed by the strips explained above, can these strips after they are placed around the head and after the fixie ren on the then exposed outer sides with those explained above Covers are provided to prevent hot air from escaping at these not to prevent places in contact with the body.

An alternative embodiment of the head area of the heat blanket, especially the thermal pad, may consist of the Head area as at least one surround profile for the head and / or is designed for the neck. Unlike the stripes, the header must rich are therefore not formed from separate sections, son The head area then has the final shape from the outset.

According to a particularly advantageous embodiment of the present Invention includes the trained as a thermal underlay Heat blanket at least one arm area covering the arm or part of the arm of a person covered by the thermal blanket can be arranged.

Through the arm area or through the preferably two arm areas can also be a patient's arms entirely or partially, for example only in the upper arm area and / or only in the lower  arm area to be included in the heat regulation. This too Measure leads to a significant improvement in thermal insulation, because one can also notice the (upper and / or lower) arm area heat loss occurs because the arms - like all extremities in general ten - compared to the hull of the risk of a higher degree of cooling cooling or hypothermia.

According to a preferred embodiment of the arm area, this is formed as at least one substantially rectangular approach, the can be wrapped around a person's arm to complete it to enclose. The ends of the overlap when wrapping sentence in this context in a practical form means with which they can be attached to each other. On in this way a tight and stable fit of the arm areas of the heat around the arm.

The at least one connecting means can be in an essential manner according to the invention

• - At least one Velcro connection and / or
• - at least one button connection,
  in particular by at least one push-button connection, and / or
• - by at least one lacing connection

act.

The thermal blanket, especially the thermal underlay, can still be at least at least partially the chest and / or at least partially the Back of a person covering upper body area and / or mind at least partially the belly and / or at least partially the Hip area and / or at least partially the buttocks area and / or at least at least partially on the lower body area covering the legs of a person point. The thermal blanket, especially thermal underlay, can therefore be used for a complete or only partial covering of a patient  or a patient.

To increase stability and protect mechanically special stressed areas, such as the head area and / or the arm area and / or the upper body area and / or the lower body rich and / or the leg area, the thermal blanket, in particular Heat pad, in certain areas expediently with min at least one reinforcement, in particular with at least one reinforcement section.

The thermal blanket, in particular a thermal underlay, is then attached to the and when storing in the operating room and in the context of the subsequent disinfection and / or cleaning less easily damaged, so that long-term reusability of the thermal blanket, in particular thermal underlay is given.

Further refinements, features and advantages of the present invention are explained in more detail below with reference to the three exemplary embodiments illustrated by FIGS . 1 to 5.

It shows:

Fig. 1 is a plan view of a first embodiment of a Wärmedec ke, in particular thermal underlay, according to the present inven tion;

FIG. 2 shows a sectional view, not to scale, of the thermal blanket, in particular a thermal underlay, from FIG. 1 along the section line II-II from FIG. 1;

Fig. 5 is a plan view of a third embodiment of a Wärmedec ke, in particular heat pad, according to the present inven tion.

Identical or similar configurations, elements or features are provided with identical reference numerals in FIGS. 1 to 5.

In Figs. 1 to 5 dei embodiments one for the body of a living being, especially a human, specific heat blanket 100 (see FIG. First embodiment according to FIGS. 1 and 2) or 100 '(see FIG. Second embodiment are shown in Figs , for example, during surgery may be employed. 3 and 4) or 100 '(see FIG. third embodiment according to Fig. 5) in each case as a heat pads on the body.

The heat blanket 100 (see FIGS . 1 and 2) or 100 '(see FIGS. 3 and 4) has a connection 10 , the heat blanket 100 "(see FIG. 5) has two connections 10 for an air hose 12 , via the warm air from a hot air source 14 , such as blower or air heating device from a powered Heizge, can be supplied.

All three exemplary embodiments have in common the feature that the hot air is distributed after switching on the hot air source 14 and after passing through the air hose 12 in the intermediate layer 30 formed as an intermediate layer, which in the three-layered thermal blanket 100 or 100 'or 100 " between the inner layer 20 formed as an inner layer, facing the body, and the outer layer 40 designed as an outer layer, facing away from the body (the intermediate layer or intermediate layer 30 is thus in an essential manner according to the invention by the inner layer or inner layer 20 facing the body and by the body facing away from the body Outer layer or outer layer 40 limited).

By the provision of the intermediate layer 30 , the warm air provided by the hot air source 14 can in any case be passed continuously under the body to be heated, so that the body parts resting on the heat pad 100 or 100 'or 100 "under any conditions be reliably warmed.

For this purpose, the inner space or "interior" of the thermal blanket 100 or 100 'or 100 "is filled with an intermediate layer material made of synthetic fabric, namely of knitted polyester fabric. This material of the intermediate layer 30 is, on the one hand, so firm, stable and rigid in the manner essential to the invention, that the passage of warm air is ensured, on the other hand, this material of the intermediate layer 30 in inventive manner has a degree of elasticity, which ensures a pressure-relieving load of anesthetized patients, in particular Ba bys and small children.

Furthermore, both the inner layer or inner layer 20 and the outer layer or outer layer 40 are not compressed so much by the arrangement of the intermediate layer or intermediate layer 30 that passage, passage, flow and / or transport of the hot air is no longer possible is (the side parts of the body who is also warmed by the warm air flowing out of the inner layer 20 ).

The outer layer 40 of the heat blanket 100 or 100 'or 100 "is airtight and airtight, for which purpose the outer layer 40 consists essentially of textile material. In contrast, the inner layer 20 of the heat blanket 100 or 100 ' or 100 " Air-permeable formed in that this inner layer 20 consists of microfiber material and in he essential to the invention has the finest, in particular pore-like openings for the outflow of the supplied warm air.

The aforementioned technical measures lead to the fact that the warm air can escape essentially exclusively on the inner layer 20 , which faces the body of a patient when using the heat blanket 100 or 100 'or 100 ". In this way, the The thermal blanket 100, 100 'or 100 ", which acts as a thermal base, simultaneously provides insulation against heat loss and additionally ensures active heat supply.

The air-permeable inner layer 20 of the heat blanket 100 or 100 'or 100 "is designed in a shade of green customary for operating areas. In contrast, the air-tight and air-impermeable outer layer 40 is kept in a light color, in particular in white, so that this outer layer 40 is less heat-absorbing and is more heat reflective and therefore warms less.

A cooler outer surface 40 also has the advantage that this Außenflä surface 40 when fixing the thermal blanket 100 or 100 'or 100 "less easily contaminated by the residues of adhesive strips, tapes or the like, because the adhesive residues at low Temperatures are less soluble and therefore essentially stick to the adhesive strip, tape or the like and do not stick to the outer layer 40 of the heat blanket 100 or 100 'or 100 ".

The reusable heat blanket 100 or 100 ′ or 100 ″ illustrated with reference to FIGS . 1 and 2 or with reference to FIGS. 3 and 4 or with reference to FIG. 5 is therefore intended for convective warming of the body and can be used, for example, during operations under the The "center point" or central area of the warming blanket 100 or 100 'or 100 "is formed here by the upper body area 70 , which - as is also the case with known warming blankets - the chest and / or the back, that is, the patient's torso area is to be assigned.

After the common features of the three exemplary embodiments according to the present invention have been set out above, the differences between the first embodiment (see FIGS. 1 and 2), the second embodiment (see FIGS. 3 and 4) and the third embodiment are shown below (see Fig. 5) explains:
The heat blanket 100 according to FIGS . 1 and 2 is essentially intended for the upper body and is shown in FIG. 1 in the spread state. This heat blanket 100 has various, particularly shaped areas, the "center" of the heat blanket 100 forming an upper body area 70 which, as with known heat blankets, is to be arranged on the chest and / or under the back of a patient.

From the upper body region 70 , two mutually spaced strips 50 a and 50 b extend in a neck cutout 72, projecting approximately at right angles. These two strips 50 a, 50 b are arranged with the thermal blanket 100 on the left and right of the neck or head of a patient. Because of their flexibility, the strips 50 a, 50 b can therefore be placed around the neck and head of a patient in order to isolate these parts of the body and to provide them with heat.

At their free ends facing away from the upper body region 70 , the strips 50 a and 50 b each have Velcro fasteners 52 a and 52 b, with which the ends can be connected. The strip 50 b has two Velcro strips 52 b which are at an angle to one another in the illustrated first exemplary embodiment, in order to enable the respective end regions of the two strips 50 a, 50 b to be connected at different angles.

The strips 50 a, 50 b are typically air-permeable on their inner side 20 facing the body in order to allow the escape of warm air. In addition, they can also be partially air-permeable on their outer side 40 , so that warm air can escape there and flow around uncovered areas of the face.

Furthermore, based on the illustration in FIG. 1, an arm area 60 a or 60 b is provided on the left or right on the upper body area 70 . These arm areas 60 a, 60 b are designed as approximately rectangular lobes that can be wrapped around the upper arms of a patient.

At their - in relation to the illustration in FIG. 1 - upper edge, the arm regions 60 a and 60 b have multiple rows of push buttons 62 a and 62 b, those with push buttons 64 a and 64 b on the - based on the illustration in FIG Fig. 1 - lower edge of the arm areas 60 a and 60 b can be joined together to fix the wrapping of an arm. The arm regions 60 a and 60 b can effectively protect the upper extremities, which are subject to hypothermia, and provide them with heat.

In the attachment areas of the narrow, head-facing strips 50 a and 50 b on the large-area rest of the heat pad 100 reinforcement sections 90 a and 90 b are provided. These protect the mechanically particularly stressed (transition) areas and accordingly increase the service life and the number of reuses of the thermal blanket 100 . The reinforcing sections 90 a and 90 b can be formed, for example, by forming the heat pad 100 in multiple layers and / or by attaching a tear-resistant, particularly stable material.

Finally, the heat blanket 100 according to FIGS . 1 and 2 can have one or more recesses 92 designed as a passage for (supply) connections. Such gap-shaped or slit-shaped or flat recesses 92 allow the use of the thermal underlay 100 in particular in the operating area (so-called “operating area”) and in intensive care, because the necessary connections, such as electrical [K] ardio ] G [ramm] electrodes and / or infusions can be guided to the patient without the complete coverage by the heat blanket 100 suffering as a result.

The second exemplary embodiment of the heat blanket 100 ′ shown in FIGS . 3 and 4 corresponds in its basic structure essentially to the first exemplary embodiment of the heat blanket 100 (cf. FIGS . 1 and 2). Unlike the first exemplary embodiment, the thermal blanket 100 'is, however, a full body blanket in which the upper body region 70 is continued by a lower body region 80 ; this lower body region 80 can cover the abdomen and also the hip part and also the buttock part and also the legs of a patient.

Particularly noteworthy in relation to the second exemplary embodiment of the heat pad 100 '(see FIGS . 3 and 4) is a hood-like two-part head region 50 a, 50 b,

• - the one on the heat blanket 100 'to be stored and of the thermal blanket 100' to bedec kenden person for heating by means of hot air escaping be brought into contact partially with the head and the neck and
• - The partial as a profile for the head and neck out forms is.

Furthermore, the heat pad 100 'according to FIGS. 3 and 4 has two arm areas 60 a and 60 b, formed on the left and right of the upper body region 70 , which are formed on the left and right of the upper body region, based on the illustration in FIG Arm or with the left arm of a person to be stored on the thermal blanket 100 'and to be covered by the thermal blanket 100 ' for heating by means of warm air escaping by the right arm from the left arm area in the top view of FIG. 3 60 a and the left arm is enclosed by the right arm region 60 b in the top view of FIG. 3.

Since the arm areas 60 a, 60 b are designed in a manner essential to the invention in the essential union in the form of triangular lobes and consequently can also be folded or placed over a person lying on the back in relation to the top view according to FIG Arm areas 60 a, 60 b in a manner essential to the invention also as a kind of "cover" with which the heat pad 100 'is equipped.

Not least for this case of use as a "cover", the arm regions 60 a, 60 b described above have in their respective end regions (= region of the approximately right angle of the essentially triangular flaps) connecting means in the form of Velcro connections 66 a, 66 b, whereby the left in the plan view of FIG. 3 arm portion 60a are two spaced-apart flauschförmige Velcro portions 66 a and the right in the plan view of FIG. 3 arm section 60 b, a thereto corresponding hook-shaped velcro portion 66 b associated, through which the free ends of the arm areas 60 a, 60 b to form a "cover" fixed to each other who can.

By means of the connecting means 66 a, 66 b arranged at the ends, the two arm areas 60 a, 60 b can be connected to one another after laying around the body (= chest area and / or back area) of the patient to form a fixed length upper body covering that keeps its configuration and position stable.

In this context, the Velcro-type connecting means 66 a, 66 b are arranged or set up at the ends of the two arm regions 60 a, 60 b so that the connecting means 66 a, 66 b connect the end regions of the arm regions 60 a, 60 b below allow different angles; this makes it possible to put the two arm areas 60 a, 60 b in different configurations and in different ways around the upper body or torso of the patient and to ensure that the end areas are still securely detachably connected.

Finally, the heat blanket 100 '- based on the illustration in Fig. 3 - in a manner essential to the invention below the upper body region 70 , that is to say in the lower body region 80 at least two leg regions 82 a and 82 b, which are arranged next to one another and are pocket-shaped and which are on the right Leg or the left leg of a person lying on his back in relation to the top view according to FIG. 3 are assigned.

These leg areas 82 a and 82 b are formed in an essential manner in the form of leg bags and / or can be detachably fixed and closed to one another in a manner according to the invention using suitable closure means, such as by means of Velcro closures 84 a and 84 b, so that the warm air supplied remains in the area of the legs and is not lost to the outside.

The leg regions 82 a and 82 b can be brought into contact at least partially with the respective leg, in particular at least partially with the respective foot, of a person to be stored on the heat pad 100 'and to be covered by the heat pad 100 ' for heating by means of escaping warm air, the respective leg, in particular the respective foot, being enclosed by the respective leg area 82 a or 82 b.

The third exemplary embodiment of the heat blanket 100 "shown in FIG. 5 essentially corresponds to the second exemplary embodiment of the heat blanket 100 '(see FIGS . 3 and 4). Unlike the first exemplary embodiment and the second exemplary embodiment, the heat blanket 100 " ( see Fig. 5), which is designed in particular as a heat blanket or heat pad for infants, toddlers or adolescents, two connections 10 for the air hose 12 , via the warm air from the warm air source 14 , such as from a current-operated heating fan or Air heating device, can be supplied.

In this connection, the "child blanket" 100 (see FIG. 5) has two such inlet options 10 in order to be able to arrange the air hose 12 depending on the side on which the small patient is being operated on the illustration of FIG. 5 can be removed, is in the non-central, but laterally offset to the two terminals 10 properly considered that the warm air before beistreicht side of the head of the small patient or of young patients, that is not directly on the head hits ,

This measure, essential to the invention, to provide two connection options 10 for the air hose 12 , distributes the warm air better; Furthermore, overheating, which is particularly virulent in the head area, is prevented (in the head area, the temperature of the warm air is the highest anyway).

The thermal pad is particularly noteworthy with respect to the third embodiment 100 '(see. Fig. 5) a hood-like design one-piece head portion 50 c,

• - the one on the heat blanket 100 "to be stored and of the thermal blanket 100" to bedec kenden person for heating by means of hot air escaping be brought into contact partially with the head and the neck and
• - The partial as a profile for the head and neck out forms is.

Finally, the arm areas 60 a, 60 b of the thermal blanket 100 "- based on the illustration in FIG. 5 - in an essential manner according to the invention not least for the case of use as a" blanket "in their respective end areas (= area of the approximately right angle the substantially triangular lobe) connecting means in the form of Schnürverbin connections 68 a, 68 b, wherein the left arm area 60 a in the top view of FIG. 5 a cord 68 a and the right arm area 60 b in the top view of FIG. 5 a corresponding cord 68 b is assigned, through which the free ends of the arm regions 60 a, 60 b can be tied together to form a “cover”.

By means of the connecting means 68 a, 68 b arranged at the ends, the two arm areas 60 a, 60 b can be connected to one another after laying around the body (= chest area and / or back area) of the patient to form a fixed length upper body covering that keeps its configuration and position stable.

In this context, the cord-like connecting means 68 a, 68 b are arranged or set up at the ends of the two arm regions 60 a, 60 b in such a way that the connecting means 68 a, 68 b tie up the end regions of the arm regions 60 a, 60 b under different Angles he leave; this makes it possible to put the two arm areas 60 a, 60 b in different configurations and in different ways around the upper body or torso of the patient and to ensure that the end areas are still securely detachable.

With regard to the further configurations, features and advantages of the third exemplary embodiment according to FIG. 5, in order to avoid unnecessary repetitions, reference may be made to the above explanations regarding the second exemplary embodiment according to FIGS . 3 and 4.
