Abstract:
PROBLEM TO BE SOLVED: To provide underbody blanket that warms the head, as well as the body of the patient, wherein the warm air circulates about the blanket to maintain an even temperature throughout, and when output from the blanket, is focused to the patient.SOLUTION: A convective underbody blanket has a head portion 10 and a body portion 12. Provided at the head portion is a non-inflatable head area 14 surrounded by a channel 18 that has arranged thereat at least one row of air apertures 22, 22', 22", 24, and 24' that are oriented toward the non-inflatable head area when the channel is inflated. At the body portion, there is provided a non-inflatable body area 26. Along each longitudinal side of the body area, there are longitudinal channels 28a, 28b, 30a, and 30b. Each of the longitudinal channels is in fluid communication with the channel that surrounds the non-inflatable head area. The longitudinal channels that sandwich the non-inflatable body area extend substantially along the length of the non-inflatable body area and are in communication with each other by way of a cross channel 36 formed at the foot end of the blanket.

PROBLEM TO BE SOLVED: To provide a convective warmer capable of optimally inflating blankets of various dimensions.SOLUTION: The convective warmer is capable of providing air to the various blankets at flow rates that optimally inflate the blankets. The convection warmer may have multiple fixed air flow rates each selectable by a user via switches 26 either electronically or mechanically. For the electronic selection of a given flow rate, a motor 6 is used. To vary the flow rate mechanically, a valve is controlled. In addition, a feedback circuit that maintains the pressure sensed at the outlet of the warmer to a preset pressure is used.

PROBLEM TO BE SOLVED: To provide a convective warmer to which blankets of different dimensions may be connected, that is capable of providing air to the various blankets at flow rates that optimally inflate those blankets to achieve the optimal clinical result for the patients covered by those blankets.SOLUTION: The blanket connected to the warmer may range from a full size adult warming blanket to a pediatric or neonate warming blanket. There is provided on each blanket a code, marking or marker, to be read by a sensor(s) provided at the outlet of the warmer, that identifies the type of blanket when the blanket is coupled to the warmer. Consequently, heated air may be automatically output by the warmer to the blanket at the appropriate flow rate of that blanket to optimally inflate the blanket without any need for intervention by a user. In addition to being used to control the flow rate of the heated air, the code from the blanket may also be used to control the temperature of the heated air to be input to the blanket.
Abstract:
Each leg of a U tube blanket is configured to have at least one row of holes extending substantially along the length thereof. The size of the holes is incrementally increased from the proximal portion that is closest to the air inlet cross section of the blanket where heated air is input to the blanket for inflating the same to the distal portion of the legs of the blanket. For an embodiment of the inventive blanket, the plurality of vent holes along each leg of the blanket are grouped into a number of sections, for illustration purposes three, with the vent holes in each section having the same dimension.
Abstract:
A convective underbody blanket has a head portion and a body portion. Provided at the head portion is a non-inflatable head area surrounded by a channel that has arranged thereat at least one row of air apertures that are oriented toward the noninflatable head area when the channel is inflated. At the body portion there is provided a non-inflatable body area. The longitudinal channels that sandwich the non-inflatable body area extend substantially along the length of the noninflatable body area and are in fluid communication with each other by way of a cross channel formed at the foot end of the blanket. The configuration of the blanket allows air input to the blanket to be circulated through the various channels, so that the heated air output from the different rows of apertures formed at the various channels has substantially the same temperature.
Abstract:
A combination underbody and overbody blanket has first and second portions sandwiching a middle portion. The first portion may be shorter than the second portion. An opening is provided at the middle portion, or at a location that overlaps the middle and first portions. The opening has a dimension sufficiently large to enable the head of a patient to pass through. At least one air inlet is provided at the middle portion to allow air to be input into the blanket. The blanket is configured in the shape of a poncho, with the first portion covering the front torso of the patient and the second portion covering the back of the patient. A tearable seal is provided at the first portion that allows the first portion to be separated into two halves to expose the front upper torso of the patient and/or to facilitate the placement of the middle portion about the neck and onto the shoulders of the patient.
Abstract:
An inflatable convective thermal blanket is designed to have at least one section on its top surface that has securely mounted thereon at least one fluid absorbent mechanism for absorbing fluids from a subject that is placed onto the blanket, or from fluids fallen onto the blanket from other sources. The one section is configured onto the blanket in such a way that it forms a well for collecting the fluids. The fluid absorbent mechanism, which may be in the form of a pad, would absorb the collected fluid to thereby minimize evaporative and cooling effects on the subject. Instead of mounting it on top of the blanket, the fluid absorbent pad may be mounted to the underside of the blanket, with appropriate holes and/or openings provided at the fluid collecting section, so that the collected fluids are drained onto the fluid absorbent pad. To enhance the input flow of air to the blanket, as well as to enable the blanket to be flatly folded for storage or shipping, a collapsible retainer mechanism is provided at the input port(s) of the blanket. The retainer mechanism opens up to a shape that facilitates the mating of an air hose to the input port. When folded to its collapsed position, the retainer mechanism, and the input port, would lie substantially copfanarty with the blanket. When configured to the position for accepting the air hose, the retainer mechanism is positioned substantially orthogonal to the blanket.

A convective warmer to which blankets of different dimensions may be connected is capable of providing air to the various blankets at flow rates that optimally inflate those blankets to achieve the optimal clinical result for the patients covered by those blankets. The blanket connected to the warmer may range from a full size adult warming blanket to a pediatric warming blanket. The convection warmer may have multiple fixed air flow rates each selectable by a user, via switch(es) either electronically or mechanically. For the electronic selection of a given flow rate, a motor adaptable to rotate a different speeds is used. To vary the flow rate mechanically, a valve is controlled to vary the amount of air that may pass to the blanket. Instead of different fixed flow rates, variable air flow rates, selectable by the user, may be used. Also, a feedback circuit that maintains the pressure sensed at the outlet of the warmer to a preset pressure may be used to eliminate the need for user intervention.
Abstract:
An underbody convective warming blanket that may be used by a pediatric or neonate patient includes a head portion configured with multiple substantially U-shaped channels each having a plurality of adjacent rows of apertures that circumscribe the head of the patient positioned on the blanket. The adjacent rows of apertures are configured on the upper layer of the blanket so as to be positioned at an orientation or angle relative to the base plane of the blanket or the head of the patient such that those apertures would substantially face the head of the patient when the blanket is inflated, so that the heated air output from the apertures is directed substantially towards the head of the patient to thereby effect an invisible dome of heated air that envelopes the head of the patient.
