Description

The present invention relates to an isolation device that is suitable for patient transportation in ambulances or within hospitals, but can also be used for protected care on ocean-going ships or drilling platforms.

Presentation of the invention

Isolation devices, in particular those that are portable, are known from the prior art. For example, an insulation suit can be named that is based on the script FR 278 89 66 A1 is disclosed. This suit completely surrounds the patient, has a helmet and various devices for monitoring the patient. However, he restricted the freedom of movement so that the patient can get an oppressive feeling. Treatment from the outside is also difficult. In addition to the patient, all connected equipment must also be transported individually, which increases the effort.

In Scripture JP 2007 175 266 A is presented a transport stretcher on which the patient can lie, surrounded by a dome. Devices or personal items can be carried in a special compartment on the top of the dome. Treatment from the outside is not possible without intervention in the dome, so that the patient cannot receive adequate medical care during transport from one protected area to another.

Finally, it is from Scripture CN 204 446 429 U an insulation device is known which allows the patient to be treated by the gloves arranged on its outer cover, for example by accessing the loosening or tightening of seat belts and the administration of medicaments which have to be stored inside, but not the protected exchange with the patient. As a result, this isolation device is particularly unsuitable for transport over long distances or for storing the patient in the isolation device for a long time.

All named devices according to the state of the art have the disadvantage that consumables which are incurred by the patient or also by the treating doctor or medic can be stored inside the device or can not be handed over to the outside in a secured manner. In addition, transportation with conventional vehicles is not possible or only with increased effort, since a coupling with existing vehicle technology is not provided.

The invention has for its object to provide an improved isolation device that facilitates the treatment of the patient, but also offers the patient a higher quality while in the isolation device.

The object is achieved with the features of claim 1, the subclaims describing further refinements.

The insulation device for patient transport comprises an inflatable, sealed chamber made of a robust, predominantly transparent material, preferably plastic, for the transport of patients lying down, gloves being arranged on the chamber, which can be inserted into the interior of the chamber and which can be accessed from outside through glove openings is. The insulation device is characterized in that a ventilation system is arranged on the chamber, the ventilation system being designed such that the chamber can be operated with overpressure or underpressure. Antiaerosol and / or gas protection and / or comparable filters are arranged on the ventilation system, a pressure-maintaining system being arranged on the chamber, which regulates the overpressure or underpressure. It is conceivable that the automatic pressure maintenance system works at +50 Pa when operating with the positive pressure and - 50 Pa when operating with the negative pressure. Centrifugal fans in a housing are preferred for the filter ventilation system.

In a special embodiment of the isolation device for patient transport, a microprocessor system and an energy supply are arranged on the isolation device. The microprocessor system enables monitoring of the battery charge level and also a possible external supply of energy. The insulation device is self-sufficient on the one hand, but also enables the control of the necessary energy e.g. for the purpose of sealing off the patient from external influences.

According to a further embodiment of the isolation device for patient transport, the microprocessor system is designed in such a way that it determines pressure, temperature and / or humidity in the interior of the chamber by means of appropriate sensors and displays it by means of a display element, and determines and displays the status of the energy supply. The energy is supplied by batteries or rechargeable batteries or externally.

According to a further embodiment of the isolation device for patient transportation according to the invention, an alarm system, a doctor call system, a data transfer device and / or comparable devices are on and / or in the chamber Facilities arranged. the data transfer device can be carried out using Bluetooth, the data can then be output or stored on external data carriers.

According to a further embodiment of the isolation device for patient transport according to the invention, a light and / or sound indicator is arranged on the chamber for the energy supply, the alarm system and / or the doctor call system or comparable devices. The operating status of the isolation device can be tracked and system faults can be signaled and recognized.

Furthermore, according to one embodiment of the isolation device for patient transport, it is provided that the chamber has a zipper that extends at least substantially around the lower edge of the chamber. This is preferably arranged at a distance of 10 to 15 cm from the chamber floor and sealed in accordance with the specifications.

According to a special embodiment of the isolation device for patient transport according to the invention, the chamber has a patient fixation system, an internal mattress, an external stretcher fixation system and / or an external folding stretcher. On the one hand, the patient can be fixed in the isolation device, but this can also be attached to existing vehicle installations by means of the stretcher-fixing system. A mattress protects the patient for longer transport.

According to a further embodiment of the isolation device for patient transport according to the invention, the chamber can be held in shape by means of at least three, preferably five transverse arches and at least one longitudinal strut. The crossbows are inserted into holding pockets attached to the chamber base and bulge the chamber out in the form of a tunnel. At least one longitudinal strut keeps the cross struts at a distance and thus the chamber in shape.

According to an embodiment of the isolation device for patient transport according to the invention, the chamber has at least one inner pocket, a transfer lock and / or interfaces for connecting external devices. In the inside pocket e.g. medical waste or personal possessions of the patient are stored, additional drugs and consumables can be safely transferred into the interior through the transfer lock during patient transport. The interfaces are sealed connections e.g. for a ventilator, an EEG or EKG. Furthermore, there can be feed lines for infusion solutions.

The technical result of the invention is to prevent the ingress of microorganisms, dust particles and chemical substances through the portable insulation device during operation with the negative or positive pressure.

The microprocessor system can be addressed and operated by means of a console. A control unit can also be provided for this purpose, which can also be used separately from the isolation device by means of remote data transmission if required.

All the seams of the chamber are preferably produced by quality welding with subsequent sealing by means of tapes made from the base material by high-temperature splicing with hot air, which ensures that the seams are not separated during operation.

All connections are designed as stationary, the absence of moving parts ensures the greatest tightness of the device and prevents incorrect assembly of the device. Exchangeable gloves and filters are an exception.

The portable isolation device for patient transportation ensures the following technical result: Prevention of the ingress of microorganisms, radioactive dust particles and chemical substances through the portable isolation device while maintaining the operation with a negative or positive pressure.

The portable isolation device according to the invention is used for the transport, for example, of burn-injured patients and patients with a weakened immune system to protect them from the “contaminated” environment and of patients suspected of being infected with particularly dangerous infectious diseases.
