Abstract
A biological fluid collection system including a collecting device, a collecting container, a first channel connecting the two, a sampling bag, a second channel connecting the sampling bag and the first tube and at least one substantially irreversible closure device in an open position on at least the first or second channel. The biological fluid may be blood. A method of collecting biological fluid such as blood using the system so that fluid in the sampling bag is substantially irreversibly prevented from entering the collecting container.
Claims21
A container system for collection of a biological fluid comprising:
- i) a collecting device;
- ii) a collecting container;
- iii) a first channel providing fluid communication between the collecting device and the collecting container;
- iv) a sampling container;
- v) a second channel providing fluid communication between the first channel and the sampling container;
- and
- vi) at least one substantially irreversible closure device in an open position provided on at least one of the first and second channels,
- wherein the substantially irreversible closure device, once in a closed position, cannot readily be restored to an open position and
- wherein the substantially irreversible closure device comprises:
- i) a lock base including:
- (a) a housing with two lateral clips to allow connection of the device to a tube and at least two internal stops and an intermediate region between the two internal stops;
- and
- (b) an orifice;
- ii) a flange including:
- a) a projection that presses into the intermediate region between the two internal stops when the flange is closed over the lock base;
- and
- b) a finger with a radial toe;
- and
- iii) a hinge around which the lock base and flange rotate with respect to each other,
- whereby the lock base and flange may be rotated around the hinge to a closed position wherein the finger is disposed within the orifice and is secured therein by the radial toe.

A container system for the collection of a biological fluid comprising:
- i) a means for collecting the biological fluid;
- ii) a means for storing the collected biological fluid;
- iii) a first fluid communication means for providing fluid communication between the means for collecting the biological fluid and the means for storing the collected biological fluid;
- iv) a means for storing initially collected biological fluid for sampling;
- v) a second fluid communication means for providing fluid communication between the first fluid communication means and the means for storing initially collected biological fluid for sampling;
- and
- vi) at least one means in an open position for substantially irreversible closure of fluid communication in the first or second fluid communication means, wherein the means for substantially irreversible closure of fluid communication, once in a closed position, cannot readily be restored to an open position;
- wherein the means for substantially irreversible closure comprises:
- i) a lock base including:
- (a) a housing with two lateral clips to allow connection of the device to a tube and at least two internal stops and an intermediate region between the two internal stops;
- and
- (b) an orifice;
- ii) a flange including:
- a) a projection that presses into the intermediate region between the two internal stops when the flange is closed over the lock base;
- and
- b) a finger with a radial toe;
- and
- iii) a hinge around which the lock base and flange rotate with respect to each other,
- whereby the lock base and flange may be rotated around the hinge to a closed position wherein the finger is disposed within the orifice and is secured therein by the radial toe.
