DESCRIPTION:
BRIEF SUMMARY
This invention has as its object an improved auscultation device.
Medical auscultation devices such as stethoscopes or sphygmomanometers which require the application to the patient's skin of an element intended to pick up a noise or a pressure are already known.
These known devices present the drawback that the first contact of the measuring element with the skin causes a sensation of cold and causes reactions from the patient, which are able to disturb the examination that it is desired to make.
This is the case in particular when it is desired to measure a parameter of the blood circulation, because a sudden sensation of cold often causes a modification of the cardiac rhythm.
Also, this sensation of cold often makes babies or young children that are to be examined scream or cry.
This invention aims at producing medical auscultation devices which prevent this drawback while being of a simple and not very costly embodiment.
This invention has as its object a medical auscultation device comprising an element intended to be applied to the patient's skin, which is characterized by the fact that it comprises on or in the vicinity of this element a heating resistance which is supplied by a contactor from an electric current source such as a battery, a light and portable device.
In a first embodiment, the invention is a stethoscope in which the electrical resistance is applied to the membrane, preferably to the face of the latter which is not in contact with the patient's skin.
The electrical resistance can consist of a filament which is glued along a winding passage to the face of the membrane.
It can also be directly made on the membrane thanks to the known technique of printed circuits.
In a particular embodiment, the resistance of the membrane is supplied with electric current by a battery placed in a case attached to the tube which connects the body of the stethoscope to the ear tips, preferably in the vicinity of the body of the stethoscope.
In another embodiment of the invention, the resistance is supplied by a small-sized battery, which is located in a case on the top of the body of the stethoscope and which can be recharged thanks to electric contacts located on the periphery of the case of the battery.
According to yet another embodiment of the invention, the electrical energy is provided to the resistance by a small-sized battery, placed in a case located on the top of the body of the stethoscope, which is supplied by multiple photovoltaic cells which are placed on the upper face of the cup of the stethoscope and which assure the automatic recharging of the battery.
According to these various embodiments, a slight heating of the membrane of the stethoscope is caused by supplying it with electric current by a switch consisting, for example, of a push button that it suffices to press for a very short time, just before the moment when the cup of the stethoscope is applied to the patient's skin.
In a second embodiment, the invention is applied to a sphygmomanometer and is characterized by the fact that the inflatable rubber pocket, which is applied to the patient's skin and inside of which pressurized air is sent to measure the arterial pressure, comprises a resistance in the vicinity of its face which is applied against the patient's skin, this resistance being supplied with electric current by a switch to heat the rubber before its application to the patient's skin.
To make the invention better understood, several embodiments taken as examples and shown in the accompanying drawing will now be described by way of illustration and without any limiting nature.
