Abstract

Cardiovertor/defibrillator with electronics (12) that receives a detection signal from a detection device (16) indicating whether a heart of a mammal is fibrillating, processes the detection signal by running a program and generates a control signal for a stimulation device (17) based on the detection signal in order to allow the stimulation device (17) to provoke defibrillation of the heart by a resuscitating stimulation in the area of the pharynx of the mammal. The apparatus has a nose plug.

Claims

1. A cardiovertor/defibrillator comprising:

a casing;

electronics arranged within said casing;

a detection device connected to said electronics;

a stimulation device connected to said electronics; and

the electronics being arranged to receive a detection signal from said detection device indicating a disorder of a body including at least one of a fibrillating heart and a heart infarct to process said detection signal and to generate a control signal for said stimulation device based on said detection signal in order to allow said stimulation device to generate a resuscitating stimulation in order to activate the respiratory centre in the brainstem and, in turn, counteract said disorder, the casing being designed as a nose plug arranged to be inserted into a nostril, and the stimulation device being arranged to stimulate a nasopharyngeal area of said mammal, the cardiovertor/defibrillator either;

being designed such that the stimulating device comprises a spraying unit for distributing a chemical composition into the nostril, or

being designed such that it comprises a thread, wire or fibre having a length such that it touches the pharyngeal area once the casing is inserted into the nostril, which thread, wire or fibre is connected to a motor and arranged to stimulate the nasopharyngeal area by a suitable mechanical movement as instructed by said electronics, or

being designed such that it comprises a wire having a length such that it touches the pharyngeal area once the casing is inserted into the nostril, which wire is arranged to provide electrical stimulation signals to said wire as instructed by said electronics.

2. The cardiovertor/defibrillator according to claim 1, wherein said cardiovertor/defibrillator comprises a nose cap connected to said casing.

3. The cardiovertor/defibrillator according to claim 1, wherein said casing is made of a flexible biocompatible material.

4. The cardiovertor/defibrillator according to claim 3, wherein said flexible material is silicone.

5. The cardiovertor/defibrillator according to claim 4, wherein said electronics comprise electronic components on a flexible substrate.

6. The cardiovertor/defibrillator according to claim 1, wherein said electronics comprise a microprocessor connected to a wave function generator, the wave function generator being arranged to produce said control signal having a wave form selected from at least one of a sinus wave, block wave, spike train or any combination thereof with a predetermined frequency, duration and amplitude.

7. The cardiovertor/defibrillator according to claim 1, wherein said detection device comprises a sensor on said casing for sensing a heartbeat signal.

8. The cardiovertor/defibrillator according to claim 1, wherein said casing comprises a through hole to allow said mammal to breath through said nostril.

9. The cardiovertor/defibrillator according to claim 8, wherein said detection device is arranged to sense breathing activity from air flow through said through hole.

10. Cardiovertor/defibrillator according to claim 1, wherein said cardiovertor/defibrillator comprises a plurality of electrodes to contact said nasopharynx and having some distance between them, such as to cause an electrical current to flow over said distance through said nasopharynx.

11. Cardiovertor/defibrillator according to claim 1, said chemical composition comprises trigemino-olfactoric stimulants comprising one or more of vanillin, amylacetate, propionic acid and phenylethylalcohol.

12. A method of counteracting a disorder of a body comprising:

detecting whether said body shows said disorder of a body including at least one of a fibrillating heart and a heart infarct;

generating a resuscitating stimulation in order to activate the respiratory centre in the brainstem and, in turn, activate the cardiovascular control centre and thus to counteract said disorder; and

wherein said resuscitating stimulation is applied to a nasopharyngeal area of said mammal.

13. The method according to claim 12, comprising implanting an implantable cardiovertor/defibrillator in or behind the nasopharynx in said mammal, which is designed to perform said detecting and said generating.
