A blood flow stimulator may help encourage blood flow in a limb of a patient. The blood flow stimulator may include a housing configured for sealing about the limb of the patient. The housing may include a sealable volume, and the sealable volume may receive the limb of the patient. The blood flow stimulator may include a seal, and the seal may be coupled with the housing. The seal may engage with at least a portion of the limb, for instance to segregate the sealable volume from a surrounding environment of the blood flow stimulator. The blood flow stimulator may include a conduit extending through the housing. The conduit mat help provide access to the sealable volume, for instance from the surrounding environment. In some examples, an adjustable stent is utilized to enhance blood flow within vasculature of a patient. A stent operator may change a size of the stent.

A heel protector (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section (101) and the foot engaging section (102) define a leg insertion aperture (104). The leg engaging section (101) defines at least one aperture (203) disposed in an ankle region (205) to permit a connection tube (1002) extending from an inflatable bladder (901) of a compression device (800) to pass therethrough. The heel protector (100) and compression device (800) work together as a rehabilitation system (1300).

There are provided a fluid-path tester and a fluid-path testing-method capable of performing classification of abnormal-modes into a problem in a system, a leakage in a dedicated tube, a problem of a failure in a suppression pressure, and the like, an analysis of the abnormal-modes, and the like in a simplified manner. PAPS valves are included, and an abnormality emulator inspecting an abnormal condition in a fluid path of a DUT by emulating characteristics of the fluid-circuit represented by each of a plurality of abnormal-modes having possibilities of occurring in the fluid path of the DUT through pressurization of a fluid pressure using a compressor-under-test and adjustment of the fluid pressure using the PAPS valves.

An air absorbing and discharging massager, comprising: a housing, an air pump, a solenoid valve, a PCB board and a silicone massaging case connected to the air pump through a nozzle rack; the air pump connected to the solenoid valve. The air pump and the solenoid valve controls the silicone massaging case to absorb or release air so as to obtain a squeezing and inflating massage effect; the nozzle rack includes a filter screen. A user is covered by the massage cavity and uses an air pump and a solenoid valve to realize an air absorbing and releasing action, so that the massage cavity can be squeezed or inflated, and the user can receive a comfortable massaging and stimulating feeling.

An ambulatory respiratory assist device utilizes a cuirass worn on the chest and/or abdomen and supported by a hip belt so that it does not place a load on the patient's shoulders. The belt also supports a ventilator that includes a pump and its power supply, valving, controls and auxiliary equipment. The device is optionally integrated with auxiliary features such as chest wall vibration, which can be achieved by utilizing cuirass pressure modulation, with shoulder or upper arm supports for simulating the tripod position, with positive pressure ventilation apparatus, or with patient monitoring. Shoulder or upper arm supports can extend directly from the belt to the shoulders or upper arms, utilized independently of the cuirass, and optionally integrated with one or more of the above-mentioned auxiliary features.

A method for external ear canal pressure regulation to alleviate one or more symptoms associated with a disorder or treat one or more disorders, the method including providing a fluid transfer device which generates a fluid flow of a fluid through an earplug, the earplug having an earplug external surface configured to sealably engage an external ear canal wall as a barrier between an external ear canal pressure and an ambient pressure; sealably engaging the earplug of the fluid transfer device with the external ear canal wall as the barrier between the external ear canal pressure and the ambient pressure; and operating the fluid transfer device to generate the fluid flow of the fluid through the earplug to achieve an external ear canal pressure differential between the external ear canal pressure and the ambient pressure effective to alleviate a disorder symptom or treat a disorder.

Described herein are various embodiments of differential air pressure systems and methods of using and calibration such systems for individuals with impaired mobility. The differential air pressure systems may include an access assist device configured to help a mobility impaired user to stand in a pressure chamber configured to apply a positive pressure on a portion of the user's body in the sealed pressure chamber. The system may also include load sensors configured to measure the user's weight exerted inside and outside the chamber. The system may be calibrated by determining a relationship between the actual weight of the user and the pressure in the chamber, where the actual weight of the user may be measured by more than one load sensor and at least one load sensor is not in the pressure chamber.

A system such as a hospital bed provides capability to monitor and alleviate the pressure points and provides oxygen and water jets to prevent and treat bed sores in bed-ridden patients. An array of balloons touching each other form a mattress of unstitched but contiguous balloons like in a conventional mattress with stitched puffs. Individual pressure sensors placed within each balloon measure and monitor pressure. Furthermore, horizontal rods which lay between the balloons perform oxygenation and provide water massage to the back of the patient body from the interstitial spaces within the unstitched mattress of contiguous balloons. The rods are elevated to raise the patient above the mattress to relieve overall pressure and enable cleaning and wipe down of the back of the patient body. The rods can elevate the entire patient body or its torso alone or the lower extremities alone to clean as desired.

A patient support apparatus includes an air supply and an air fluidization therapy bed including a fluidization space and a fluidizable medium positioned in the fluidization space. The air fluidization therapy bed receives a flow of pressurized air from the air supply. The flow of pressurized air operable to fluidize the fluidizable medium. The patient support apparatus is configured to provide other therapies, such as pulmonary therapies, in addition to the air fluidization therapy.

The invention relates to a massage device (1) for massage by means of pressure waves, comprising a housing (2) having a grip section (4) and a massage section (6), at least one first chamber (8, 10) having an opening (12) in the massage section, leading towards the outside, and a drive means (30) for changing the volume (V1) of the first chamber (8), wherein the drive means (30) has at least one coil element (32, 34) and at least one movably guided magnetic core (38) arranged parallel to the coil element (32, 34) for acting on the first chamber (8).
