A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

Techniques disclosed herein relate to gesture-based control of diabetes therapy. In some embodiments, the techniques may involve identifying at least one gesture indicative of utilization of an injection device for preparation of an insulin injection based on user activity data obtained from a wearable device disposed on an arm of a user. The techniques may further involve based on the at least one identified gesture, determining whether the insulin injection meets criteria of a proper insulin injection. The techniques may further involve outputting information indicative of whether the criteria is satisfied based on the determination.

A hemodialysis system includes: a hemodialysis machine configured to provide hemodialysis treatment to a patient, wherein the hemodialysis treatment includes circulating extracorporeal blood of the patient through an extracorporeal blood circuit; a first oxygen saturation sensor device configured to measure oxygen saturation corresponding to the extracorporeal blood of the patient in the extracorporeal blood circuit; a second oxygen saturation sensor device configured to measure oxygen saturation corresponding to blood flowing within the patient; and at least one controller configured to determine one or more oxygen saturation phase shift (OSPS) values or one or more transcutaneous travel time values corresponding to the patient based on oxygen saturation measurements from the first oxygen saturation sensor device and the second oxygen saturation sensor device.

The present invention relates to the intravenous injection aid for indicating vein, comprising: a compression strap; a binding means disposed at the opposite ends of the compression strap; a near-infrared lamp disposed at the compression strap; and a controller disposed on the compression strap for controlling the near-infrared lamp. The present invention as mentioned above may not only indicates vein with high visibility but also keep the vein from swaying or moving even during intravenous injection, so the intravenous injection can be carried out safely and efficiently.

Devices, kits and methods for determining the site of intramuscular injection in adult and child patients are disclosed. The device includes a top element and two legs that are configured to be fastened in a first position and a second position. When placed in the first position and second position, the device forms a substantially triangular region having a center that corresponds to the site of injection.

A bilateral humeral guide for intraosseous infusion includes a three-dimensional mirror symmetric shell configured to fit on either shoulder of a patient, the shell being symmetric about a plane bisecting an alignment hole configured to aid positioning of the shell on the shoulder by aligning the alignment hole on acromion of the shoulder, and two insertion-site indication holes symmetrically positioned on two opposite sides of the plane, the insertion-site indication holes including a left and a right hole each configured to indicate insertion sites for intraosseous infusion through the shell to a target region of a left or right humerus of the patient when the shell is positioned on the shoulder corresponding to the respective humerus.

A method of providing and/or injecting octreotide acetate to a subject in need thereof includes storing the octreotide acetate in a cartridge of a multi-use multi-dose injector provided with a variable dose setter and actuator. The injector includes a needle configured for subcutaneous administration of the octreotide acetate, the octreotide acetate having a concentration of 2,500 μg/mL. The method further includes providing, on the injector, a plurality of indicia only at prescribed doses of 50 μg, 100 μg, 150 μg and 200 μg settable via the dose setter without indicia between said prescribed doses; and permitting setting of a dose of the octreotide acetate by rotation of the variable dose setter, wherein the injector is configured to provide at least one audible feedback during the rotation.

Wearable devices can be used to provide therapy to users and/or to monitor various physiological parameters of the user. In some cases, therapy can be triggered automatically based on the monitored physiological parameters reaching or exceeding predefined thresholds.

A bilateral humeral guide for intraosseous infusion includes a three-dimensional minor symmetric shell configured to fit on either shoulder of a patient, the shell being symmetric about a plane bisecting an alignment hole configured to aid positioning of the shell on the shoulder by aligning the alignment hole on acromion of the shoulder, and two insertion-site indication holes symmetrically positioned on two opposite sides of the plane, the insertion-site indication holes including a left and a right hole each configured to indicate insertion sites for intraosseous infusion through the shell to a target region of a left or right humerus of the patient when the shell is positioned on the shoulder corresponding to the respective humerus.

Some implementations of the present invention relate to systems and methods for managing disruptive sleep disorders. In some cases the described systems and methods may detect an episode of parasomnia, such as sleep paralysis, sleepwalking, night terrors, chronic nightmares, sleep hallucinations, sleeping disorders associated with post-traumatic stress disorder, or a similar sleep disturbance, and provide a stimulus to wake the user from the episode of parasomnia. Accordingly, in some cases, the present invention comprises a sensor to monitor a user's physiological indicators to first determine if the user is asleep and then identify the onset of an episode of parasomnia, and a mechanism for providing a sensory stimulus to wake the user. Other implementations are also described.
