Description

BACKGROUND

Technical Field

The present disclosure relates to a medical battery module for vacuum mattresses and heating mats, the medical battery module comprising a battery compartment and a battery that is removable from and insertable into the battery compartment, wherein the battery is electrically connectable or connected to a heating support, wherein the battery, compartment is padded with a shock-resistant material and the shock-resistant material is at least partly sheathed by a liquid-repellent film. The disclosure further relates to a vacuum mattress or a heating mat comprising such a medical battery module.

Background Information

In medical emergencies, it is generally necessary to treat a patient quickly and efficiently. Various types of vehicles are used to transport patients to a hospital. In this respect, stretchers, vacuum mattresses and the like are used in the vehicles. The requirements for such an apparatus are set out in EN 1865 and EN 1789, respectively, that inter alia specify common minimum requirements for the testing, equipping for the transport, construction of stretchers and other patient transport means that are used in ambulances or rescue vehicles for the treatment and transport of patients.

SUMMARY

The currently most common apparatus is usually only suitable for the use within vehicles or buildings and usually not for a. longer use outside vehicles and buildings,

A temperature-regulating apparatus can be used to provide an apparatus for mobile use outside vehicles. In emergency situations, it has been shown that patients can be helped by supplying cold or heat since e.g. the blood vessels can dilate due to the supply of heat. The blood flow is thereby stimulated and the muscles can relax. Due to the supply of heat, patients can also be helped after a medical emergency, for example an accident or an acute illness, through the supply of heat.

In contrast to this, the blood vessels contract on the supply of cold and the muscles can tense up. The exiting of blood, e.g. into surrounding tissue, can be prevented in this respect. By regulating the temperature to different temperatures, a patient can thus be treated in a more targeted manner outside medical facilities or inside or outside vehicles even in the case of very serious injuries.

A disadvantage of such temperature-regulating stretcher supports is that they are often cabled within the vehicle and can thus form a hazard zone in the vehicle. Due to the cabling of such temperature-regulating apparatus, the service life of such apparatus can also be impaired.

It is an object of the present disclosure to provide an improved power supply for a temperature-regulating apparatus that has a longer life and that can be used without a cabling effort. It is a further object of the present disclosure to provide an apparatus that makes it possible to minimize a space requirement within a vehicle.

This object is satisfied by a medical battery module having the features disclosed herein.

Such a medical battery module for vacuum mattresses and heating mats comprises a battery compartment and a battery that is removable from and insertable into the battery compartment, wherein the battery is electrically connectable or connected to a heating support, wherein the battery compartment is padded with a shock-resistant material and the shock-resistant material is at least partly sheathed by a liquid-repellent film, and wherein the battery module is either separate from the heating support or lies on the heating support.

Such a battery module can be easily used with both a vacuum mattress and a heating mat Depending on the application, the battery module can be fixedly or releasably coupled to the vacuum mattress or the heating mat so that the use of such an apparatus can be adapted to the given situation.

The battery compartment can be manufactured from the shock-resistant material and a battery housing can then be arranged in the battery compartment to remove a battery from or to insert a battery into the housing, wherein the battery and the battery housing can then be protected against shocks by the battery compartment.

The battery compartment can comprise two half shells. Such battery compartments can be manufactured particularly simply.

The shock-resistant material or the battery compartment can also consist of two or more components.

A control unit of the battery and of the heating support can be arranged at one side of the medical battery module. In this respect, the use of the battery module can be made particularly simple.

The shock-resistant material can comprise a material selected from the group comprising plastics, thermoplastics, foam comprising isocyanates and polyols, polyurethane, TPU, styrofoam, and the combinations thereof.

Such materials can be used in an injection molding process to manufacture the battery compartment, the battery housing, or components thereof in a simple, reproducible, and cost-effective manner.

A base of the medical battery module can be arranged, in particular directly, on the heating mat or the vacuum mattress. Space in the vehicle can be saved in this respect.

The medical battery module can be completely sheathed by the liquid-repellent film except for an opening at the front side or the base of the battery compartment. The battery is hereby protected against liquids.

The battery compartment preferably comprises a battery housing and the battery can be removed from the battery housing and can be repeatedly inserted into the battery housing. An electrical connection between the battery and the electronic components of the vacuum mattress or the heating mat can be improved by such a battery housing and protection against an entry of a liquid into the vacuum mattress or the heating mat can also be improved by such a battery housing.

The battery housing preferably comprises a multi-part housing that is at least liquid-repellent, preferably liquid-tight. Since the battery housing can be configured as liquid-repellent, an entry of liquid into the battery housing can be avoided so that the risk of a short circuit in one or more electronic components, which can be arranged in the vacuum mattress, can be minimized.

The heating support particularly preferably has a temperature-regulating film, wherein the temperature-regulating film can be regulated to an at least substantially constant temperature in the range from 15 to 42° C., preferably from 16 to 30° C., in particular from 20 to 30° C., specifically from 22 to 26° C., wherein the temperature can be set in dependence on the patient by a control unit. These temperature ranges are perceived as pleasant by patients who are transported on the vacuum mattress and enable a heating or a cooling of the body of the patient.

The cover preferably has a frame in which the battery is arranged. The battery can be repeatedly and more precisely inserted into the battery housing by such a frame.

A seal is preferably arranged between the cover and the upper shell as well as the lower shell. Since the cover is usually arranged at the outer side of the support, the seal usually likewise seals from the outside such that no liquid, such as water, detergent, disinfectant, blood or the like, can enter the vacuum mattress.

The battery housing and/or the cover is/are preferably manufactured from a plastic, preferably in an injection molding process. The components of the battery housing can hereby be manufactured in a cost-effective and reproducible manner.

The seal is preferably arranged between the cover and a groove of an outer frame, wherein the outer frame connects the upper shell to the lower shell. The connection between the housing parts of the battery housing can be improved by such an outer frame.

The control unit is preferably arranged in the region of the connection between the upper shell and the lower shell, preferably arranged at the outer frame. The control unit can hereby be particularly securely attached to the battery housing.

The battery housing preferably further has a reception space for at least one board on which at least one electronic circuit is provided to communicate with the battery. Such an electronic circuit can thus be arranged more securely in the vacuum mattress than without such a battery housing.

In accordance with a further aspect of the disclosure, the disclosure relates to a vacuum mattress comprising a medical battery module, wherein the medical battery module is welded or adhesively bonded to the vacuum mattress and is electrically connected to a heating support of the vacuum mattress. With a heat-regulating vacuum mattress, patients can, for example, in an emergency situation be supported by the addition of heat.

The heating support can be arranged at an upper side of the vacuum mattress. It has namely been found that the vacuum mattress as such is relatively sensitive to maintain its vacuum properties so that it is advantageous to apply the heating support, in particular directly, to an enveloped vacuum mattress. Thus, already existing vacuum mattresses can also be retrofitted with a heating mat or a battery module of the initially mentioned type.

A liquid-repellent layer can additionally be arranged on the vacuum mattress. The heating support or further components of the vacuum mattress can hereby be protected against liquid. The liquid-repellent layer can be arranged on the heating support at the upper side of the vacuum mattress. It should be noted here that the upper side of the vacuum mattress is the side of the vacuum mattress at which a patient is treated.

An electrical cabling of the heating support can likewise be arranged at the upper side of the vacuum mattress and is preferably likewise arranged under the liquid-repellent layer so that the electrical cabling of the heating support can also be protected against liquids.

An electrical coupling of the electrical cabling can be provided and can be guided through the liquid-repellent layer to establish or to provide an electrical connection with the batten module.

The battery module can be arranged on the vacuum mattress such that the electrical coupling is covered by the battery module. In particular such that the electrical coupling is covered in a liquid-repellent manner by the battery module.

In accordance with a further aspect of the disclosure, the disclosure relates to a heating mat comprising a medical battery module, wherein the medical battery module is separate from the heating mat and is electrically connectable to a heating support of the heating mat.

The advantages that were discussed above in connection with the medical battery module apply accordingly to the vacuum mattress and to the heating mat.

The heating support can be arranged at an upper side of the heating mat. A liquid-repellent layer can likewise be arranged on the healing mat. The liquid-repellent layer can preferably be arranged on the heating support at the upper side of the heating mat.
