Publication number: 20240151338Abstract: Fluid connector assemblies that seal off fluid paths in the respective connectors are disclosed. When connectors of a fluid connector assembly are connected to each other, respective compressible members in the connectors are displaced, allowing downstream fluid passage through the fluid connector assembly. The connectors maintain a connection by a snap mechanism that provides a threshold retention force. When an external force greater than the threshold force is applied to the fluid connector assembly, the snap mechanism may no longer maintain the connectors together, causing the connectors to decouple from each other. However, each of the compressible members can return to their respective original positions and shapes to seal off respective fluid paths in the connectors, thus preventing further downstream and upstream flow through the fluid connector assembly and limiting or preventing fluid loss.Type: ApplicationFiled: November 9, 2022Publication date: May 9, 2024Inventors: Aman DESAI, Abin Austin, Mohammed Mehtab KHAN

Publication number: 20240100300Abstract: A flow restriction device includes a proximal housing configured to couple to a fluid collection device, a distal housing configured to couple to a catheter assembly, an intermediate housing interposed between the proximal housing and the distal housing and an internal fluid channel extending transversely therethrough. The flow restriction device also includes a fluid shield assembly having an enclosure coupled to an end of the distal housing and a split septum coupled to an end of the enclosure, the split septum comprising a flexible material with a centrally disposed slit. The fluid shield assembly provides for connection of a female connector to a male connector of the distal housing through the slit of the split septum, and to contain fluid within the enclosure and split septum upon disconnection and withdrawal of the female connector from the male connector. Blood collection systems and fluid shield assemblies are also provided.Type: ApplicationFiled: September 27, 2022Publication date: March 28, 2024Inventors: Alireza Salehi Borojerdi, Mohammed Mehtab Khan, Niranjan Lekkala, Sudharshan Mundadishetty, Prabhath Kakaraparthi

Publication number: 20240100315Abstract: A fluid connector device for a blood collection system is disclosed. In order to be safely used with different gauges, the fluid connector device can regulate blood flow therethrough based upon the catheter gauge. For example, when 18-to-22-gauge catheters are used, the fluid connector device regulates the blood flow by positioning a slider assembly (within the fluid connector device) to a setting that allows a single channel to transmit blood through the fluid connector device into a fluid inlet and out of a fluid outlet of the fluid connector device. Alternatively, in another example, when 24-gauge (or greater) catheters are used, the slider assembly can be actuated to a new position, which allows multiple channels to transmit blood into the fluid inlet and out of the fluid outlet. By regulating blood flow, the fluid connector device can limit or prevent hemolysis, while being universally used with different catheters.Type: ApplicationFiled: September 11, 2023Publication date: March 28, 2024Inventors: Mohammed Mehtab KHAN, Amarsinh Deeliprao JADHAV, Abin AUSTIN

Publication number: 20240100246Abstract: Pump assemblies for use with an IV set are described herein. A pump assembly includes a rotatable crank, a piston rod, and a diaphragm assembly. The crank includes a crank profile defining a plurality of lobes. The piston rod includes a first follower and a second follower spaced apart from the first follower. The rotation of the crank relative to the piston rod causes the piston rod to reciprocate relative to the crank. The diaphragm assembly includes a housing and a diaphragm member. The diaphragm member is coupled to the housing and cooperatively defines a volume in fluid communication with the IV set. The diaphragm member is movable between an extended position configured to draw in fluid from the IV set and a contracted position configured to expel fluid into the IV set. The diaphragm member is coupled to the piston rod to reciprocate the diaphragm member.Type: ApplicationFiled: September 23, 2022Publication date: March 28, 2024Inventors: Mohammed Mehtab Khan, Karthik MR, Saushthav Shrivastava, Akshay Srikanth, Abhishek Krishnan

Publication number: 20230390491Abstract: A pressure detection system includes a body having an internal chamber with input and output ports and a flexible membrane fluidically sealed to an exposed opening of the chamber to prevent a fluid passing through the chamber from passing through the exposed opening. The membrane is configured to change shape responsive to an increase in pressure caused by the fluid within the chamber satisfying a predetermined threshold. In some implementations, the membrane includes or is part of an identification mechanism which moves outwards, away from the chamber, as the pressure increases to indicate the pressure increase. In some implementations, the identification mechanism includes markings on the surface of the membrane, and an image sensing device reads the markings, and provides an indication of a current pressure associated with the fluid in the chamber based on a variation in the markings from a default state.Type: ApplicationFiled: December 22, 2022Publication date: December 7, 2023Inventors: Mohammed Mehtab KHAN, Abin AUSTIN, Aman DESAI, Kanjimpuredathil Muralikrishna MENON, Ryan CALLAHAN
