Methods of producing randomized ultrasound waves for sonodynamic therapy

Disclosed are methods of producing randomized ultrasound waves for providing sonodynamic therapy. The method includes coupling a sonodynamic therapy device with an array of piezoelectric transducer elements to a skin surface. A controller is configured to generate an electrical drive signal to produce ultrasound waves to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.

Methods of using planar or defocused acoustic waves for non-invasive sonodynamic therapy

Disclosed are methods of using planar or defocused acoustic waves for providing non-invasive sonodynamic therapy. The method includes acoustically coupling an array of piezoelectric transducers to a patient. A controller is configured to generate an electrical drive signal at a frequency selected from a range of frequencies, modulate the drive signal, and drive the transducer with the modulated drive signal at the frequency to produce modulated acoustic waves to produce an average acoustic intensity sufficient to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.

Patient warming device with patient access

A patient warming device with patient access for maintaining normothermia and/or treating hypothermia is provided. The device includes a first compliant layer and a second compliant layer sealed together around an outer border to contain a liquid between the two layers and to form a wrap that surrounds and conforms to a body portion of a patient. A plurality of flaps extends from opposite sides of a generally longitudinal central portion of the wrap, such that one or more flaps from the opposite sides fasten to each other to surround the body portion. The flaps are openable during functional use to provide access to an underlying patient body surface. A continuous fluid flow path extends between the first compliant layer and the second compliant layer between a fluid inlet and a fluid outlet to carry liquid and deliver heat through the wrap.

THERMAL SYSTEM WITH OVERSHOOT REDUCTION

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically pauses thermal treatment of the patient prior the patient reaching a target temperature. During the pause, the controller assesses a reaction of the patient and changes a temperature of the fluid only inside the thermal control unit if the patient is likely to reach the target temperature without further thermal treatment. However, if the patient is unlikely to reach the target temperature without further thermal treatment, the controller restarts the thermal treatment. The controller may pause thermal treatment again prior to reaching the target temperature and assess the patient's reaction. In some embodiments, the controller may selectively include and exclude a fluid reservoir in a circulation channel within the thermal control unit.

CORE BODY TEMPERATURE MEASUREMENT
20240216168 · 2024-07-04 ·

Continuous core body temperature measurements are made during hypothermic operations, where the core body temperature of the patient is lowered to reduce swelling. Caregivers monitor the patient's core body temperature to prevent damage that can occur to the patient if the patient's core body temperature becomes too low. To accurately determine the core body temperature of the patient, a temperature monitoring system measures the temperature at or near the surface of the patient and through at least a portion of a thermal block at multiple locations.

Compressive cryo-hemostatic device

This is a device, belonging to the medical and hospital artifacts industry, developed to accelerate the hemostatic process for patients undergoing radial punctures, partially compressing the artery subjected to treatment; said cryo-hemostatic device is essentially presented in the form of a wristband (1), providing end bands (2) providing velcro-based closing, interconnected by an intermediate band (3) below which a first cryogenic reservoir pad is located (4), which can be filled with a saline substance by the action of a syringe connected to the first connection nipple (5) attached to the first tube (6), flanked by the second external reservoir pad (7), also provided with a second connection nipple (8), attached to the second tube (9).

NON-INVASIVE, SYSTEMS, DEVICES, AND METHODS FOR SELECTIVE BRAIN COOLING
20190151142 · 2019-05-23 ·

Methods, systems, and devices are disclosed for providing selective and non-selective cooling and warming of a patient. Multiple embodiments of devices are disclosed for performing rapid induction and maintenance of therapeutic hypothermia either in a hospital setting or in the field so that hypothermic treatment can be quickly instituted before significant tissue damage occurs. Methods are also disclosed for targeting brain cooling by irrigating the upper airway, aerodigestive tract, and/or more generalized cooling by irrigating the esophagus and/or stomach.

ORGAN RESTRAINT FOR INFLAMMATION REDUCTION AND ATRIAL FIBRILLATION PREVENTION

An organ restraint device includes a first end portion including a fluid inlet channel, a second end portion including a fluid outlet channel, a medial body portion coupled between the first end portion and the second end portion. The medial body portion includes one or more fluid channels that couple the fluid inlet channel to the fluid outlet channel and a plurality of tension adjustment apertures

Inflatable convective pad for surgery

An inflatable convective pad for warming a person during surgery has two ends, two sides, and at least two openings, each located in an area of the pad between the two ends and between a respective side and the center of the pad. The openings, which may be in the form of slits, allow the threading of a sheet or the person's arms through the pad to restrain the arms during surgery.
