Connector structure and a connector structure of a sampling tube of a patient respiratory tubing
View Patent ↗A connector structure for a fluid tube is provided. The connector structure comprises: a first connector body connected to a fluid tube; a second connector body, the first connector body and the second connector body being connectable to each other and comprising mating surfaces to create a fluid tight seal between the first connector body and the second connector body, wherein the mating surfaces comprise only vertical and/or oblique parts and are configured to press tightly against each other and form a fluid tight seal with the locking mechanism; and a locking mechanism, wherein the first and the second connector body are configured to detach from each other when the locking mechanism is not used.
1. A connector structure for a fluid tube for connecting to a gas analyzer, the connector structure comprising:
a locking mechanism comprising a mechanism loaded by a resilient locking element;
a first connector body connected to a fluid tube; and
a second connector body formed from a sidewall of a housing of the gas analyzer;
the first connector body and the second connector body being connectable to each other and comprising mating surfaces to create a fluid tight seal between the first connector body and the second connector body, wherein the mating surfaces comprise only vertical and/or oblique parts and are configured to press tightly against each other and form the fluid tight seal with correct usage of the locking mechanism, the locking mechanism disposed on the sidewall of the housing adjacent to the second connector body; and
the first and the second connector body are configured to fall off from each other by the effect of gravity force without correct usage of the locking mechanism.
2. The connector structure as claimed in claim 1 , wherein the mating surfaces comprise flat surfaces.
3. The connector structure as claimed in claim 1 , wherein the mating surfaces comprise conical surfaces.
4. The connector structure as claimed in claim 1 , wherein the mating surfaces comprise curvilinear surfaces.
5. The connector structure as claimed in claim 1 , wherein the mating surfaces are formed without substantially protruding components.
6. The connector structure as claimed in claim 5 , wherein the mating surfaces do not provide any support for a friction based loose connection between the mating surfaces.
7. The connector structure as claimed in claim 1 , wherein the connector structure further comprises resilient elements configured to boost the detaching or falling off of at least one of the first connector body and the second connector body relative to each other without correct usage of the locking mechanism.
8. The connector structure as claimed in claim 7 , wherein the resilient elements comprise spring elements.
9. The connector structure as claimed in claim 1 , wherein the resilient locking element comprises a spring element.
10. The connector structure as claimed in claim 1 , wherein at least one of (i) the fluid tube is a sample tube of a patient respiratory gas tubing and (ii) the second connector body is a part of a gas analyzer.
11. The connector structure as claimed in claim 1 , wherein the second connector body is a part of the patient respiratory tubing.
12. A connector structure of a sampling tube of a patient respiratory gas tubing for connecting to a gas analyzer, the connector structure comprising:
a locking mechanism comprising a mechanism loaded by a resilient locking element;
a first connector body connected to a fluid tube; and
a second connector body;
the first connector body and the second connector body being connectable to each other and comprising mating surfaces to create a fluid tight seal between the first connector body and the second connector body, wherein the mating surfaces comprise only vertical and/or oblique parts and are configured to press tightly against each other and form the fluid tight seal with correct usage of the locking mechanism, wherein the mating surface of the second connector body is formed from a sidewall or a bottom of a housing of the gas analyzer, and wherein the locking mechanism is disposed on the sidewall or the bottom of the housing adjacent to the second connector body; and
the first and the second connector body are configured to fall off from each other by the effect of gravity force without correct usage of the locking mechanism.
13. The connector structure as claimed in claim 12 , wherein at least one end of the sampling tube comprises the first connector body.
14. The connector structure as claimed in claim 12 , wherein at least one end of the sampling tube comprises the second connector body.
15. The connector structure as claimed in claim 12 , wherein the both ends of the sampling tube comprise the first connector body or the second connector body.
16. The connector structure as claimed in claim 12 , wherein the mating surfaces comprise flat surfaces, conical surfaces or curvilinear surfaces.
17. The connector structure as claimed in claim 12 , wherein the mating surfaces are formed without substantially protruding components.
18. The connector structure as claimed in claim 12 , wherein the connector structure further comprises resilient elements configured to boost the detaching or falling off of at least one of the first connector body and the second connector body relative to each other without correct usage of the locking mechanism.
19. The connector structure as claimed in claim 12 , wherein the locking mechanism comprises a mechanism loaded by a resilient locking element.
