An intravenous (IV) tubing fitment is provided. The IV tubing fitment includes a unitary body. The unitary body includes a first end configured to couple to a first tubing, a substantially hemispherical surface adjacent to the first end, and a cylindrical body adjacent to the substantially hemispherical surface. The cylindrical body including a plurality of wings and is configured to receive a second tubing. The unitary body is configured to be received into a mating recess of a fluid delivery device such that the substantially hemispherical surface is uniformly mated with a substantially identical surface of the mating recess, and the cylindrical body is positioned outside of the mating recess.

A system and method for correcting a volume of fluid delivered by a fluid injector during an injection procedure is described. The method included determining and compensating for a volume factor associated with compliance of the fluid injector system and correcting for the volume by one of over-driving the distance that the drive member travels in a fluid reservoir, under-driving the distance that the drive member travels in the fluid reservoir, or lengthening or shortening a fluid delivery time.

A parenteral nutritional diagnostic system, apparatus, and method are disclosed. In an example embodiment, a parenteral nutritional diagnostic apparatus determines muscle quantity and muscle quality of a patient's psoas muscle to determine a nutritional status of the patient. An image interface is configured to receive a medical image including radiodensity data related to imaged tissue of the patient. The apparatus also includes a processor configured to use the medical image to determine a tissue surface area for each different value of radiodensity and determine a distribution of the tissue surface area for each radiodensity value. The processor is configured to determine muscle quality by locating a soft tissue peak within the distribution that corresponds to a local peak in at a region related to at least one of muscle tissue, organ tissue, and intramuscular adipose tissue. The processor determines the nutritional status of the patient based on soft tissue peak.

The present disclosure describes a system for the delivery of therapeutic substances to the cavities of a patient. The system can include a wearable micropump that is fluidically coupled with a handpiece. The handpiece can be inserted, for example, into the middle ear via a surgical tympanotomy approach. The system can enable a controlled injection of a therapeutic substance directly into the patient's cavity.

An implant system is provided, which includes an implant, including an implant body and an electrode disposed on the implant body; and a hollow needle, which is configured to be percutaneously advanceable into tissue of a subject. The hollow needle is shaped so as to define a lumen dimensioned to house the implant; at a distal end of the hollow needle, a distal end opening configured to facilitate passage of the implant therethrough from the lumen; and a lateral wall shaped so as to define a window therethrough to the lumen. Other embodiments are also described.

Apparatus and methods for monitoring and delivering a cell suspension. In certain examples, the apparatus comprises a reservoir containing the cell suspension, a cannula, and a liquid transfer mechanism configured to transfer the cell suspension from the reservoir to the cannula. The apparatus can also comprise an agitation mechanism to agitate the cell suspension, and a monitoring device to quantify a concentration of cells transferred from the reservoir to the cannula.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user’s body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user’s outer skin layer. The system further may include an applicator for inserting the cannula into the user’s skin and/or applying an adhesive pad to the skin.

An infusion system comprises an infusion set (30) with one or more advanced features including tube set strain relief (10), infusion pumps having heat exchange abilities and two-direction pumping abilities (100), Piezo pump devices (200), reservoirs (220, 240) made from expanded tubing, and oil impregnated pump plungers (302). An exemplary strain relief (10) includes an adhesive layer (12) such as pressure sensitive adhesive (PSA) secured to a base (14). The base (14) rotatably receives a pin (18) of a tube holder (16). The pin (18) is captured within an opening (22) of the base (14) to allow 360 degree rotation of the tube holder (16).

A monitoring device for monitoring the fluid balance of an animal or human body. The device includes a body weight sensor for continuously or periodically weighing the body, a fluid delivery device for providing a controllable supply of fluid to the body, a urine output sensor for determining the urine output of the body, a processor. The processor is adapted for determining a total fluid outtake of the body and a fluid outtake due to perspiration and respiration by taking a signal provided by the body weight sensor and a signal provided by the urine output sensor into account, and providing a control signal to the fluid delivery device to regulate a volume, flow velocity or flow rate of the fluid delivered to the body, so as to maintain a predetermined fluid balance in the body.

An infusion system for subcutaneous delivery of a fluid to a subject is disclosed. The infusion system comprises a source of a fluid; a fluid delivery system; a first fluid conduit in fluid communication with the source of the fluid and the fluid delivery system; a fluid injection device configured to be inserted into the skin of a subject for delivering the fluid to the subject; a second fluid conduit in fluid communication with the fluid delivery system and the fluid injection device; and a support frame attached to the source of the fluid and the fluid delivery system, wherein the support frame is configured to mount the source of the fluid and the fluid delivery system on a region of a head of the subject. The fluid delivery system moves the fluid from the source of the fluid, through the first fluid conduit, through the second fluid conduit, and through the fluid injection device.
