Abstract

The invention relates to a novel respiratory motion detector (RMD) which is used to observe the physiological respiratory motion of a patient and which is based on infrared motion detection (PIR technology). The inventive detector can be used during the day and at night in order to detect chest expansion with each inhale and exhale and to detect the warm exhaled air flow. The invention is suitable for both adults and new-borns as well as for use in veterinary medicine. In the event of a prolonged respiratory arrest, the electronic system can be used to trigger a local and/or remote alarm.

Description

MOTION DETECTION SYSTEM RESPIRATORY

1. Introduction:

The cardiac arrest (CA) is in most cases the initial stage of death. Sudden death is a natural death that occurs unexpectedly in a subject in full swing. It is increasingly observed in the general population and the causes are many:

• Cardiac Origin (coronary disease, arrhythmias, ...). Sudden cardiac death is often the first symptom of coronary artery disease and is responsible for 50% of cardiac deaths. In France, an estimated 60,000 annual number of sudden death, 80% of CHD. • vascular origin (ruptured cerebral aneurysm or aortic) • pulmonary origin (massive pulmonary embolism, sleep apnea ...) • Metabolic Origin (electrolyte disorders, alcohol, drugs, poison, CO, ..)

In the situation of sudden death, RA is characterized by sudden loss of consciousness, lack of ventilatory movement and absence of peripheral pulse. Only the restoration of movement and effective ventilation IE as soon as possible offers hope for survival with name TOTOTIJITO ™ sequelae. The upstream accident prevention is obviously capital.

The only current means of prevention for at-risk subjects is cardiac monitoring and / or respiratory with skin contact electrodes. These technical means are available practically in the hospital or in specific situations at home. Indeed, the financial cost of monitoring and the ongoing need for skin contact electrodes make it through difficult large-scale or home monitoring. Yet many clinical situations the patient's home or hospital (excluding ICU) require supervision 24 hours 24 hours or during sleep at least a vital function.

The technique of monitoring lung function described below provides a solution both in terms of cost of the apparatus, that of dermal connection problem of electrodes to the patient.

2. Principle:

Respiratory motion detector (DMR) is a new concept of observation of the physiological respiratory movements of an individual, based on the principle of motion detection by infra-red (PIR technology). Day and night, it can detect the amplification of the chest to each inhalation and exhalation and the hot air flow expired, both in adults and in the newborn, as well as veterinary medicine. For prolonged breathing of the individual, the electronic system allows the initiation of a local alarm and / or remotely. 3. Applications:

-φ- Noninvasive Respiratory Monitoring and without skin contact ( "non-invasive patient observation") in patients hospitalized in unmarked units (out of intensive care and care middle). -φ- Noninvasive Respiratory Monitoring and without skin contact ( "non-invasive patient observation") animal veterinary -φ- Monitoring sleep apnea. Monitoring -φ- home of sudden death in adults. -φ Prevention of sudden death of the newborn (in the absence of risk factor or need for cardiac and respiratory monitoring contact).

4. Description:

The operation of the DMR is based on the detection of passive movement by infrared (passive infra-red motion detector: PIR) and the initiation of an appropriate response. The material may comprise 3-8 PIR detectors ( "PIR sensor") disposed around and at a distance (50 to 150 cm) from the thorax and head of the individual. PIR detectors are of type Heimann or Murata. They are all connected to the same integrated circuit of classical logic controller ( "control logic") via an interface and an amplifier for PIR sensor. In this new concept, it is not intended to filter the light background interference, that in this situation, the PIR sensors must have the greatest possible motion detection so the greatest sensitivity (see below). They are equipped with Fresnel lenses increasing their sensitivity to very small movements. The "control logic" is related to a switch relay triggering a local alarm or remotely by wave iradio (fϋgure 1): 4. If at least one of the system PIR detector senses a breathing or other movement, the electronic circuit keeps the relay alarm switch to OFF.

• Φ If no system detector capture of respiratory movements in a given time (programming 10, 20, 30 seconds), turned ON relay and the alarm is activated locally or remotely via radio transmission.

-Φ- The initiation of this system is automated by the pressure sensor at the bedding (weight of the individual).

The DMR also includes a warning light LED type and a discrete sound (click) for objectify each sensing movement by the individual. The device's power is supplied to the network 220V but a battery with a battery life of 24 hours is also planned.

Figures 2 and 3 show a DMR placed on a movable arm mounted on the wall. In this situation, PIR sensors detect motion from above.

Figures 4 and 5 show a DMR disposed in a frame and a bed superstructure (child in this case), the PIR sensors detect the movements laterally here. A combination of different detection fields (top or side) is obviously possible in difficult situations. Details PIR sensors:

PIR sensor technology is now well known and has been published in many journals. The "dual sensor PIR detectors" are now the most widely used.

The DMR can be equipped for example with a sensor dual pyroelectric element having a high sensitivity and a rectangular window for a finer spectrum.

• Technical specifications for example: o Detection range: 51 ° x 51 ° o Sensitivity: 3.9 mVpp o Wavelength: 5-14 microns o Power supply: 3-15 V o Filter: 0 o Temperature: -25 to + 55 ° C o Fresnel lens polyethylene, refractive index.
