It is known to use electrically heated covers in the form of electric blankets to completely prevent the human body from getting cold.

However, this has the disadvantage of generating dry heat and excessive perforation.
on), which is inconvenient for patients in hospitals and clinics in that the heat does not provide a comforting effect, even though it is heated. Additionally, these electrically heated blankets pose safety concerns, even though they are equipped with overheating thermostats and switches that shut off the power when a predetermined temperature is reached. be. Moreover, such heat-generating blankets cannot be technically produced in such a way that they can supply cold air on demand.

The present invention provides a cover for use as a blanket for lying down or sitting up.
If a particular person requires cooling, by incorporating a hot air and/or cold air generator, thereby supplying heated normal air instead of hot air to the blanket or human body, a corresponding design may be used. The aim is to completely solve this problem by providing a device that can also supply cold air so that the blanket can be used for therapeutic purposes. Furthermore, the objective is achieved that the air hits the human body evenly and the development of pressure loads in the gap between the blanket and the human body is avoided.

Accordingly, the present invention provides: a) a sealed internal fully formed sheet formed from a two-layer weldable plastic sheet or plastic sheet fully lined fabric, held together at its ends by welding or adhesive joints; ．． It is formed of a plurality of air duct-like interconnections in the interior of the blanket, interconnected in a strip-like or perforated manner by welding or gluing, on the one hand forming a duct device for sending cold and hot air, and in one layer or in two layers. double blankets with air outlets and air supply connections fixed to the ends of the blanket or to one of the two layers; b) multiple air outlet openings at the contact or adhesive connections; and C) a casing connected to the interior of the blanket by an air supply hose connected to an air supply device and having a self-supporting or supporting and hanging or suspension device, a suction-discharge blower contained therein, an air outlet of the casing. a cold air generation and supply system consisting of a nearby heater, at least one purification and/or air humidification filter, and/or an oxygen or mixed gas supply connection and/or a cooling device near the air inlet. Specifically, it provides a device for heating or cooling a person who is lying or sitting up.

The invention further provides: a) formed from a weldable plastic sheet consisting of two layers or a fabric fully lined with a plastic sheet;
held together by welding or adhesive joints at their ends. A plurality of air duct-like interconnections are formed inside the blanket, forming a closed interior and interconnected in a band-like or perforated manner by welding or gluing, and on the other hand forming a duct device for conveying cold and hot air. , with double blankets in which one or both layers are provided with an air outlet and the interior of the blanket has an air supply connection fixed to the end of the blanket or to one of the two layers; b) at welded or glued connections; C) a force enclosing double-layered blanket on all sides, made of a breathable and air-distributing fabric; d) connected to an air supply device; a casing connected to the inside of the blanket, with a free-standing or supporting and hanging or suspension device, a suction-discharge blower contained within it, a heater located near the air outlet of the casing; recumbent or seated with a cold and hot air generation and supply device consisting of one purification and/or air humidification filter and/or oxygen or mixed gas supply connection and/or (one cooling device near the air inlet) It aims to provide a device for warming and cooling people.

With the device configured in this way, it is possible to supply hot or cold air to the human body using the blanket in conjunction with the blower and heater connected to the blanket. Therefore, unlike in the case of known electric blankets, dry warm air is not generated on the human body.
Instead, the hot air supplied has a certain degree of atmospheric humidity, the degree of which is determined by the atmospheric humidity of the surrounding air into which the hot air is drawn. In some cases, the supplied air is further humidified. When the hot air generator is not in use, the blower supplies cold air to the blanket. If the hot air generator has several connecting parts, a single hot air generator can be used to fully supply hot air to several blankets, or to supply N cold air to them with the heater switched off. can do. Since the fabric is breathable, it is connected to a cover made of a suitable fabric that encloses the entire blanket, ensuring uniform air distribution.

The air coming out of the blanket is evenly distributed on both sides of the blanket in the gap between the blanket and the cuff.

There are many possible uses for such a device. The patient may require a separate heat supply due to its use as a heating appliance in the home and the specific heat needs of special geriatric patients.

If necessary, the patient can also be given a full supply of cold air, which is especially effective on very hot days, and cooling generally promotes vitality even in the fittest of people, and who suffers from burns. It has a sedative effect on patients. If this blanket is formed into a cylindrical or small bowl shape and cool air is supplied to it, the blanket can be used to aid the progress of treatment, and can also be used on the human body for local treatment purposes. can. Thus, for example, it can be wrapped around the patient's legs in cylindrical form, or it can be applied as a small thong over the cardiothoracic area to provide a full sedative effect in cases of heart disease.

Additionally, in tropical regions, the device is used to cool people and can replace expensive air conditioner equipment that is expensive to operate.

This device is used to supply warm lice when a person is not sufficiently warmed up.

Further developed advantages of the invention are summarized in the claims.

The invention will now be explained in more detail on the basis of non-limiting examples and the accompanying drawings.

The apparatus shown in FIGS. 1 and 2 consists of a blanket 10 and a hot air generator 70. Blanket 10 is constructed of two walls, consisting of two layers 11 and 111, preferably a weldable plastic sheet or a woven plastic sheet-backed fabric in the form of cedar. two layers 11
and 111 are all welded or glued together near the rounded end 12. The welded or glued connections at the ends are designated by the reference numeral 15 (FIG. 1).

Blanket 10 consists of a rectangular piece of fabric which, when folded in the middle at right angles to the longitudinal direction, halves the two pieces of fabric, resulting in two layers 11 and 1111116 with folds at the edges of the blanket. They communicate with each other through the Tenmoku.

Meanwhile, the remaining three ends 12a, 12b and 12c are glued or welded together.

The two end-welded or end-glued layers 11 and 111 form a cold and hot air ducting device 20) rJt6, which entirely surrounds the interior 13 and is constituted by a plurality of interconnected air duct-like sections 21 in the interior 13. , interconnected by welds or adhesives 40, either in the form of bands, as shown at 41 in FIG. 1, or in a perforated manner, as shown at 42 in FIG. This perforated weld is configured as a disk-shaped weld 42a, but it is also possible to configure the weld in a different shape.This is used for connecting the two layers 11 and 111, The entire duct system for sending the air is designated by reference numeral 41a. These bonded parts 4°0 are such that air supplied through the entire interior 13 of the blanket 10 is
They are arranged alternately so that the force balls can flow through the three. Combinations of alternating or staggered arrangements and web-like connections also have advantages.

Cold and hot air is supplied to the interior 13 of the blanket 10 via an air supply connection 30 which is connected to a hot air generator by a flexible hose 71.

The layer 11 or both layers 11 and 111 has an air outlet 25 near the air duct-like portion 21 in order to supply the human body with cold and hot air that can be supplied to the interior 13 of the blanket 10 using a hot air generator. This is layer 11 and/or both layers 1
1 and 111. In order not to reduce the air output of the air outlet 25, the air outlet is located adjacent to or near the weld or bond 40 (FIG. 1).

As shown in FIG. 2, the weld bond 40 has an opening 125 through which the air escaping from the air outlet 25 is evenly distributed over the surface of the blanket 10.

This is particularly advantageous if the blanket 10 has air outlets 25 only in the layer 11 and is covered with a cover 50. Air escaping from the air outlet 25 flows through the opening 125
through the blanket 10 to the upper surface of the blanket 10, where the blanket 10
Since it is evenly distributed between the upper part of the cover and the upper part of the cover, the cooling and heating results are good. Furthermore, the openings 125 serve to avoid any compression between the blanket 10 and the person using the blanket. As a precaution, the air supply connection 30 or flexible hose 71

The interior 13 of the blanket adjacent to the edge 12 is rounded on all sides.
In order to distribute the air amount uniformly, the air free outlet section 16 is
layer 11 and/or layer 1 carrying the air outlet 25
1 and 111. The incoming air passes through the air free outlet section 16 without any disturbance and from there proceeds to the area of the air outlet 25 through which the air (1) can escape. It is preferable not to be interconnected by welds or adhesives 40 in the vicinity of the free outlet section 16, so that air can flow through the air free outlet section 16ff without hindrance.

Blanket 10 can also be used as a single piece of cloth encased in a cuff or covered with a cuff or jacket 50 (FIG. 2). Since it is made of Kaz-5OU breathable fabric, the air outflow of the air outlet 25 can reach the human body using the blanket. A regular blanket or pillowcase is suitable for this.

In order to use the blanket 10 as a bedding or a fastener, one or more fasteners, etc. 60.6
Since 0a and 60b are attached and extend to two or three adjacent ends μ of blanket 10, there is one or two insertion opening sounds VI crab. Bedding 1 shown in Figure 3
