Abstract

The electronic oxygen regulator adjusts automatically the amount of oxygen, in litres and submultiples, to be delivered to the patient on the base of the oxygen or carbon dioxide concentration detected non-invasively in the blood.

Description

Descnption Electromc Oxygen Regulator with Memory
Technical Field The invention relates to the medical oxygen delivery to patients m hospital or at home In the oxygen-therapy is essential to provide the patient with the right amount of oxygen that may vary continuously
Background Art Till today, the doctor or the therapist adjusts manually the oxygen to be delivered to the patient For this adjustment, he takes into consideration the oxygen saturation with a taking of a blood sample, for example The oxygen saturation m the blood vanes continuously therefore the doctor must control the patient and the exams at short intervals to adjust manually the oxygen flow as required
Disclosure of Invention
The system regulates automatically the amount of oxygen, m litres and submultiples, to be delivered to the patient on the base of the oxygen or carbon dioxide concentration in the blood A sampling system senses the oxygen or carbon dioxide concentration in the blood via a non- invasive sensor On the base of this data, the regulator mcreases or decreases the amount of oxygen to be delivered to the patient The Electromc Regulator stores all vanations occurred dunng the last 24 hours that may be sent to an external printer for reference or studies The Regulator has adjustable alarms
Bnef Description of Drawings
The sampling system (A), via the non-mvasive sensor (C), senses the oxygen and/or carbon dioxide concentration m the blood On the base of this data, the valve (B) mcreases or decreases the amount of oxygen to be delivered to the patient
Best mode for carrying out the invention
The best mode for carrying out the invention is to incorporate in one device an electromc board for detecting the concentrations of oxygen and/or carbon dioxide in the blood with a special valve that regulates the flow of oxygen to the patient The board detects the data thanks a non-mvasive sensor of the type easily found on the market for the pulseoximetry

Claims

Claims
The combination of the three devices (A, B and C) to obtam the automatic regulation of the oxygen flow to the patient
AMENDED CLAIMS
[received by the International Bureau on 19 May 2000 (19.05.00); new claims 2-6 added; other claim unchanged (1 page)]
The combination of the three devices (A, B and C) to obtain the automatic regulation of the oxygen flow to the patient The system is completely independent It does not reqmre the help of further appliances to regulate the oxygen flow to the patient The system may be used for every apphcations that reqmres the regulation of the oxygen flow It is suitable for every kind of patient The sampling system is totally non-invasive and gathers the data continuously It s very simple to use It does not reqmre the assistance of a doctor or a techmcian It may be operated by the patient or his family The data mav be sent via telephone to a control centre on request or in case of alarm
STATEMENT UNDER ARTICLE 19(1)
The amendments have not any impact on the description or drawings Thev simply better define the invention
The claim number 2 relates to the device itself It's a standalone unit It does not depend on other appliances or devices (such as respirators) to control and supply oxygen to the patient One compact unit incorporates the sampling system and the valve that control the oxygen flow
Claim number 3 states the applicability of the system It may be used for every application that reqmres the regulation of the oxygen flow It's suitable for every kind of patient and for every kind of pathology It's not required that the patient is connected with a ventilator
Claim number 4 regards the sampling system The oxygen and carbon dioxide concentration in the blood is gathered via a non-mvasive sensor (such as a finger clip sensor for pulseoximeter) Therefore the sampling process is very easy fast and user friendly You don't need mtra-venous electrodes This enables a continuous sampling of the data The sensor may be left in place without πsk or distress for the patient The continuous samphng is essential to achieve a perfect control of the oxygen flow
The above reiates also to Claim number 5 The device is ideal for home care treatment The Regulator does not require the assistance of a doctor Once the sensor is applied to the patient, the Regulator do all the work It's not essential the continuous bedside monitoring of an assistant
Claim number 6 relates to transfer of information between the Regulator and a control centre The stored data may be sent via telephone upon request of the doctor In an alarm situation, the transfer of the data via telephone is automatic This is another feature that make it ideal for the home care treatments
