Publication number: 20040064076Abstract: Massaging and compressing the lungs of a patient has been proven effective in loosening mucus buildup. Devices and methods for this purpose have been designed for patients older than infants and toddlers. A method for massaging and compressing the lungs of infants and toddlers has been developed using a device similar to those used for older patients. Such devices use pulsating air to inflate and deflate bladders that are in contact with the patient and apply pressure to the upper torso of the patient. For older patients, the devices are typically made into a vest and fitted on the patient. For infants and toddlers the device, herein called a J-blanket, having the same bladder arrangement is spread flat on a suitable surface and the patient placed on the J-blanket. This reduces the physical trauma to these very young patients. The J-blanket™ can be fitted with sensors to provide important feedback related to the patient's well-being.Type: ApplicationFiled: September 27, 2002Publication date: April 1, 2004Inventor: Jagadish Bilgi

Spherical valve bodies movably are provided in the valve chambers, respectively, each for closing one inlet port and one exhaust port. Shafts extend from the valve bodies, respectively. Each shaft has an end portion passing through one exhaust port and protruding from the housing. Electromagnetic actuators are coupled to the end portions of the shafts, respectively.Type: GrantFiled: June 25, 1998Date of Patent: March 12, 2002Assignee: Nitto Kohki Co., Ltd.Inventor: Haruki Nakao

Publication number: 20020022791Abstract: An entirely self-contained, patient-worn apparatus for deep vein thrombosis (DVT) prophylaxis, and other conditions includes an inflatable/deflatable bladder disposed against an extremity such as the upper calf, foot, or hand of a patient, or within a cast. An inelastic member is preferably used to fully enclose the bladder and body part, such that compressive forces are directed substantially entirely against the body part of the patient when the bladder expands, thereby conserving the power and reducing the volume of pneumatic compression required to operate the device. Given this conservation of energy, the invention may be battery operated from a source immediately proximate to the bladder arrangement, enabling the entire device to be self-contained and, in fact, worn by the patient. The reduced volume also allows the use of miniaturized components including the compressor motor and compressor.Type: ApplicationFiled: September 18, 2001Publication date: February 21, 2002Applicant: John K.

Patent number: 6315744Abstract: A chair type air massager includes a chair body having a seat, a back rest and a plurality of massage bags embedded therein, and a leg massage device having a pair of leg accommodating grooves and a plurality of massage bags provided in correspondence to the leg accommodating grooves. The leg massage device is capable of moving between a first position where the leg massage device is disposed in front of the seat and is connected to the chair body, and a second position where the leg massage device is separated from the chair body. The leg accommodating groove is capable of accommodating therein at least one leg of a user sitting on the seat of the chair body when the leg massage device is disposed in the first position, and the lower leg accommodating groove is capable of accommodating therein at least one leg of a user who is not sitting on the seat of the chair body when the leg massage device is in the second position.Type: GrantFiled: December 16, 1999Date of Patent: November 13, 2001Assignee: Toshiba Tec Kabushiki KaishaInventor: Katumi Inaba

Patent number: 6254556Abstract: A vest for a human body has an air core coupled to a pulsator operable to subject the vest to pulses of air which repetitively applies and releases pressure to the body. The vest has a cover having a pocket accommodating the air core. The pulsator has diaphragms connected to a d.c. electric motor with a rotary to reciprocating motion transmitting mechanism operable to generate air pulses in the air core.Type: GrantFiled: March 12, 1999Date of Patent: July 3, 2001Inventors: Craig N.
