Definitions
- the invention relates to a thermal blank, in which between an inner layer and an outer layer, an intermediate layer and / or a space for für manufactoring, for manufactoring, for flowing through and / or transporting of heat air is arranged.
- Thermal blankets of the type mentioned initially serve for tempering a body covered with the thermal blanket by supplying heat air.
- thermal blankets are used in particular, but not exclusively, in the medical field to prevent heat loss of persons to be treated, whose independent heat regulation is disturbed or temporarily suspended.
- the thermal blanket is placed over the patient's body or under the patient, and the heat conducted through at least one supply tube exits in a planar manner on the underside of the thermal blanket facing the body in order to heat the body.
- the underside can be made of polyester.
- the inner layer which faces the body and is permeable to the hot air
- the inner layer which faces the body and is permeable to the hot air
- the hot air substantially impermeable outer layer formed an intermediate layer or space may be arranged.
- This intermediate layer of the thermal blanket can be filled with a material that is not only permeable to air, but also ensures pressure-relieving storage, for example, of anesthetized patients.
- the heat blankets of the prior art are thus placed with their body-facing inner layer under the body and / or on the body of the patient. These not only isolate it but also convectively heat it, i. with outgoing hot air. Due to the convective heat supply, cooling or undercooling of a body to be o perated is prevented in a reliable manner.
- the monitoring extends, for example, to cardiac functions of respiration, body temperature and the like. The like. This monitoring is usually done by sensors that are attached to the body.
- the invention provides for the use of the thermal blanket in the medical field, wherein according to a further advantageous embodiment, the thermal blanket is used in surgical operations.
- the core idea of the invention is to integrate sensors, in particular for detecting a vital function, from the outset into the thermal blanket by providing the inner layer or also the intermediate layer with sensors.
- the sensors may, for example, be sensors for detecting the skin resistance, the respiration, the pulse, the cardiac currents or the body temperature.
- the fact that the thermal blankets are used as heat pads on the body it is ensured that the sensors remain sufficiently in the body contact.
- the application of the thermal blanket on the body also ensures that the sensors remain fixed in the correct position on the body.
- the advantage of the invention is the fact that the application or removal of the sensors on or from the body is accompanied by the application or removal of the heat blanket. In this way, the procedure of separately mounting and removing the sensors is avoided.
- sensors can be sensors which can be fixed to thermal blankets. It should be noted that common Thermal ceilings of the type mentioned by the following structure:
- inner layer at least one microfiber layer which is permeable to air, d. H. is designed for the warm air permeable;
- At least one spacer / storage fabric or knitted fabric in particular at least one polyester fabric, or knitted fabric, for passing through, for passing through, for flowing through and / or for transporting the hot air;
- outer layer or outer layer at least one textile layer which is impermeable to air, i. is designed for the hot air impermeable.
- the fixing agents must be selected so that sensors can be fixed to thermal blankets having this specific structure and these specific materials.
- the sensors should therefore consist of a material which is insensitive to common textile care or detergent. This takes into account the fact that thermal blankets are often subjected to cleaning.
- the sensors are made of a material that is resistant to body perspiration and body evaporation. In this way, the functionality of the sensor is preserved, even if body odors or perspiration occur during an operation. It should also be ensured that the sensors are arranged to insulate each other in a heat-insulating manner. This is particularly desirable in temperature sensors, since in this way a mutual influence of the sensors is prevented.
- the sensors are made of a material that can be subjected to sterilization and / or disinfection.
- the sensors can be fixed on the inner layer and / or inside the inner layer via a holder.
- the brackets may be, for example, snap fasteners, Velcro fasteners or connectors, which are incorporated in the thermal blanket.
- Such holders can also be provided for the sensors which are fixed in the intermediate layer and / or within the intermediate layer.
- a practicable variant of the invention provides that the sensors are woven or sewn into the inner and / or intermediate layer.
- the sensors are held for example by transverse and / or longitudinal threads.
- the contacting and the connection of the sensors with each other via electrically conductive yarns and / or threads is given.
- electrical conductors may be integrated as threads and / or yarns in the inner layer and / or in the gap to provide the necessary electrical connections between the sensors. It has been shown that the wiring between the sensors can be made such that conductor threads are mounted in textile threads of the thermal blanket. The conductor threads can be woven into the thermal blanket. Short description of the drawing
- FIG. shows in a schematic representation:
- Fig. 1 is a plan view of an embodiment of a thermal blanket gem. of the present invention
- a heat blanket according to the invention is shown, which is provided with the reference numeral 100.
- the thermal blanket 100 has a terminal 10 for an air hose 12 through which warm air may be supplied from a hot air source 14, such as from a powered heating fan.
- a hot air source 14 such as from a powered heating fan.
- the hot air is then distributed in the intermediate space 13 of the double-layered thermal blank 100 between the two layers, i. between the inner layer 15 and the outer layer 16.
- the intermediate space 13 is bounded by the inner layer 15 and by the outer layer 16.
- the outer layer 16 of the thermal blanket 100 is in this case formed impermeable to air, to which end the outer layer 16 essentially consists of a coating of polyurethane.
- the inner layer 15 of the thermal blanket is permeable to air so far as this inner layer 15 has the finest, especially pore-like openings for the outflow of hot air supplied.
- any air-permeable inner layer of fabric, knitted fabric and knitted fabric can be used. The aforementioned technical measures mean that the hot air can emerge substantially exclusively from the inner layer 15, the when using the thermal blanket 100 faces the body of a patient. In this way, the thermal blanket 100 at the same time provide insulation against heat loss and in addition to an active heat.
- the outer layer 16 may also consist of a rubberized material. It is conceivable that the material is a polyurethane coating.
- the air hose 12, which supplies the warm blank 100, the warm air is air-permeable fabric, wherein the inner side of the air hose 12 can be reinforced with knitted fabric. This ensures that no hot air can escape from the air hose 12 and the hot air flowing through the air hose 12 is forwarded even with existing kinks of the air hose 12.
- knitted fabric has a depressurizing effect, d. H. It can counteract pressure loads, for example, the result of the fact that self-weight surgical equipment such as hoses during surgery on body parts.
- As material for the bottom fabric or knit polyester may be provided.
