A disposable blood sampler for a blood braid of a blood bag includes a blood taking needle cannula, a threaded cannula, a blood braid clamp, a connecting pipe, a needle inserting sheet and a blood braid. The blood taking needle cannula includes a tubular threaded structure at both ends, a bottom port of the threaded cannula is connected with the blood taking needle cannula, and an upper port of the threaded cannula includes symmetrically distributed clamping slots extending to a middle lower part of the wall. Grips are arranged on the outer wall surface of the blood braid clamp, and the blood braid clamp is arranged in the threaded cannula. The grip is arranged outside the clamping slot, and the connecting pipe is directly inserted into the upper port. An inner cavity in which the needle inserting sheet is placed is arranged inside the inner part of the connecting pipe.

The inventive apparatus is a device for collecting a target volume of blood in a collecting bag connected to a collection needle with a flexible tube. The device has a plate for the collecting bag and a clamping device for clamping the flexible tube. The device also has a bearing element having a bearing surface, and a clamping element with a clamping surface. The clamping element is able to move between an open position in which the flexible tube positioned between the bearing and clamping surfaces is not deformed and a closed position in which the flexible tube positioned between the bearing and clamping surfaces is closed off. The device also has a control unit configured to determine the volume of blood collected and move the clamping element from the open position to an intermediate position, when the determined volume of blood collected reaches a predetermined volume.

A specimen transfer device adapted to receive a blood sample is disclosed. The specimen transfer device includes a housing and an actuation member. A deformable material is disposed within the housing and is deformable from an initial position in which the material is adapted to hold the sample to a deformed position in which at least a portion of the sample is released from the material. A viscoelastic member is disposed within the housing between the material and the housing and between the material and the actuation member. The viscoelastic member is engaged with the actuation member and the material such that movement of the actuation member from a first position to a second position deforms the material from the initial position to the deformed position.

The invention relates to a device for connecting a cannula to a container under reduced pressure, in particular a blood culture flask, including an inflow opening for connecting to the cannula or to a connection tube connected to the cannula, an outflow opening for connecting to a hollow pin for piercing a closure of the container, and a tight fluidic connection of the inflow opening to the outflow opening. According to the invention, a reservoir which is separated from the fluidic connection and contains a specified gas quantity is connected to the fluidic connection with the interposition of a valve which is preferably open towards the fluidic connection.

An integrated catheter is disclosed having a body defining a channel to direct a biological fluid therethrough, a connection port defined in the body, in which an extension tube is fluidly coupled to the connection port, a vented access port in fluid communication with the extension tube, the vented access port spaced apart from the connection port, an integrated catheter operatively connected to the body to direct a biological fluid into the body, and a distal access port defined in the body, the distal access port configured to be in fluid communication with a removable sample collection container. An initial biological fluid volume directed through the body is directed into the extension tube via the connection port and into the vented access port.

In a method embodiment, an example method for simultaneously filling balloons with water, using an apparatus sufficiently compact to be operated while being held by hand, is disclosed. The method includes attaching the apparatus to a water supply. The apparatus includes a fitting comprising an inlet configured to connect to the water supply and a bulkhead joining the at least three branch assemblies. Each branch assembly includes a tube and an automatically-sealing balloon with a neck disposed around and removably attached to the tube. The method further includes simultaneously providing water from the attached water supply to each balloon of the balloon-filling apparatus. The method further includes detaching one or more of the balloons from the balloon-filling apparatus using a force comprising gravity each detached balloon and the water contained therein. Each detached balloon automatically seals upon detachment.

Disclosed embodiments relate to a collection device for bodily fluids comprising a tubular material with a first end and second end. A portion of the first end is configured to be secured to a user and the tubular material may be folded over itself to form a first sheath and a second sheath. In some applications, the fluid collection devices described may be secured to a user using interlocking loops.

A vacuum pad may include a top layer forming a top surface of the vacuum pad; a bottom layer forming a bottom surface of the vacuum pad; and a plurality of spacers located between the top layer and the bottom layer such that an interior space is formed between the top layer and the bottom layer. The interior space may have at least one channel extending around at least one spacer of the plurality of spacers. The vacuum pad may also include an outlet tube in fluid communication with the interior space, where the top layer includes a plurality of holes. A vacuum system may include the vacuum pad along with a canister and a vacuum source for moving fluid from the vacuum pad to the canister.

A specimen mixing and transfer device adapted to receive a sample is disclosed. The specimen mixing and transfer device includes a housing, a material including pores that is disposed within the housing, and a dry anticoagulant powder within the pores of the material. In one embodiment, the material is a sponge material. In other embodiments, the material is an open cell foam. In one embodiment, the material is treated with an anticoagulant to form a dry anticoagulant powder finely distributed throughout the pores of the material. A blood sample may be received within the specimen mixing and transfer device. The blood sample is exposed to and mixes with the anticoagulant powder while passing through the material.
