Abstract

A tube for a ventilation system ( 1 ) for newborns is provided with a first section ( 7 ) comprising a heating wire ( 14 ), an electrical conductor ( 15 ), and a first connector ( 9 ) and a second connector ( 10 ), and with a second section ( 8 ) comprising a heating wire ( 16 ) extending over at least a certain portion of its length, an electrical line ( 17 ) extending over at least a certain portion of its length, and a first connector ( 11 ) and a second connector ( 12 ), wherein the second section ( 8 ) comprises a temperature sensor ( 18 ), wherein the electrical and pneumatic connection of the first section ( 7 ) with the second section ( 8 ) via the connection of the second connector ( 10 ) of the first section ( 7 ) is achievable by either connecting to the first connector ( 11 ) of the second section ( 8 ), so that the second section ( 8 ) is substantially heatable, or by connecting to the second connector ( 12 ) of the second section ( 8 ), so that the second section ( 8 ) is substantially not heatable.

First claim

The invention claimed is:

1. A tube for a ventilation system for newborns comprising:
a first section comprising a heating wire, an electrical line, and a first connector and a second connector; and
a second section comprising a heating wire extending over at least a certain portion of its length, an electrical line extending over at least a certain portion of its length, and a first connector and a second connector, the second section including a temperature sensor; and
electrical and pneumatic connection of the first section with the second section via the connection of the second connector of the first section being achievable by either one of two different alternative configurations, including (a) a first configuration in which the second connector of the first section is connected to the first connector of the second section so that the second section is heatable, or (b) a second configuration in which the second connector of the first section is connected to the second connector of the second section so that the second section is substantially not heatable.

2. The tube according to claim 1 wherein the first section is connectable to a respiratory humidifier and the second section is connectable to a Y-piece close to the patient.

3. The tube according to claim 1 wherein the heating wire of the first section and/or of the second section is formed as a high-impedance two-wire line.

4. The tube according to claim 1 wherein the electrical line of the first section and/or of the second section is formed as a low-impedance, two-wire signal or measurement line.

5. The tube according to claim 4 wherein:
the temperature sensor is configured as a thermocouple and is integrated into the second connector of the second section;
the thermocouple is adapted to bridge the low-impedance, two-wire signal or measurement line; and
a connection piece in or at the second connector of the second section is adapted to bridge the high-impedance heating wire line.

6. The tube according to claim 3 wherein:
the temperature sensor is configured as a thermocouple and is integrated into the second connector of the second section;
the thermocouple is adapted to bridge the low-impedance, two-wire signal or measurement line; and
a connection piece in or at the second connector of the second section is adapted to bridge the high-impedance heating wire line.

7. The tube according to claim 1 wherein the electrical contacts of the connectors are arranged on end surfaces thereof such that, when the connectors are connected end to end to each other, the electrical contacts are protected from being touched unintentionally from the outside.

8. The tube according to claim 1 wherein the first section is longer than the second section.

9. A ventilation tube system comprising:
an exhalation tube;
an inhalation tube upstream of a respiratory humidifier;
an inhalation tube downstream of the respiratory humidifier, such downstream inhalation tube including:
a first section comprising a heating wire, an electrical line, and a first connector and a second connector; and
a second section comprising a heating wire extending over at least a certain portion of its length, an electrical line extending over at least a certain portion of its length, and a first connector and a second connector, the second section including a temperature sensor;

electrical and pneumatic connection of the first section with the second section via the connection of the second connector of the first section being achievable by either one of two different alternative configurations, including (a) a first configuration in which the second connector of the first section is connected to the first connector of the second section so that the second section is heatable, or (b) a second configuration in which the second connector of the first section is connected to the second connector of the second section so that the second section is substantially not heatable.

10. A ventilation tube system according to claim 9 wherein at least the downstream inhalation tube is formed as a medical-grade, single-use or disposable article.

11. The ventilation tube system according to claim 9 wherein the first section is connectable to a respiratory humidifier and the second section is connectable to a Y-piece close to the patient.

12. The ventilation tube system according to claim 9 wherein the heating wire of the first section and/or of the second section is formed as a high-impedance two-wire line.

13. The ventilation tube system according to claim 9 wherein the electrical line of the first section and/or of the second section is formed as a low-impedance, two-wire signal or measurement line.

14. The ventilation tube system according to claim 13 wherein:
the temperature sensor is configured as a thermocouple and is integrated into the second connector of the second section;
the thermocouple is adapted to bridge the low-impedance, two-wire signal or measurement line; and
a connection piece in or at the second connector of the second section is adapted to bridge the high-impedance heating wire line.

15. The ventilation tube system according to claim 12 wherein:
the temperature sensor is configured as a thermocouple and is integrated into the second connector of the second section;
the thermocouple is adapted to bridge the low-impedance, two-wire signal or measurement line; and
a connection piece in or at the second connector of the second section is adapted to bridge the high-impedance heating wire line.
