  • Patent number: 7497870
    Abstract: 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.

  • Patent number: 7488306
    Abstract: To prevent fluid collected at a contaminated needle from being splattered to the environment when the housing of a needle protection device is pivoted to enclose the needle, a bias member is provided in the needle protective housing to provide damping for the needle as the needle is moved within the housing. By damping the movement of the needle relative to the needle housing, splattering of the fluid that results from the jerky movements of the needle due to sudden acceleration/deceleration of the needle relative to the housing are absorbed and/or suppressed.

  • Publication number: 20080317605
    Abstract: A pump is provided that includes a body made at least partially of an elastomeric material and an inlet port and an outlet port, with each port being coupled to the body. The pump further includes a flow passage formed in the body and extending between the inlet port and the outlet port, with at least a portion of the flow passage being normally closed and with the inlet port being fluidicly uncoupled with the outlet port when the pump is in a free-state condition. An actuating device is coupled to the body and is operable for sequentially deforming the body to create a cavity within the normally closed portion of the flow passage, the cavity being in fluid communication with the inlet port, thereby drawing a packet of fluid from the inlet port into the cavity and propagating the cavity and the packet of fluid contained therein toward the outlet port.

  • Publication number: 20080306424
    Abstract: A flow-through fluid reservoir includes a body with a first fluid port, a member movable within the body by an actuator to increase or decrease a volume of a chamber defined by a sidewall of the body. The actuator has a second fluid port. Movable member has a fluid path therethrough such that fluid ports are in fluid communication irrespective of the position of the movable member or the volume of chamber. A shaped slot on the shell of the actuator and a projection on the body cooperate to constrain relative movement of the body and actuator along a path corresponding to the shaped slot. The slot advantageously may include a stop intermediate therealong. A canted aspect of the slot may be used to initiate relative movement of the member within body. The body includes an end wall through which the first fluid port communicates. A shroud is defined by a coaxial extension of the sidewall beyond the end wall to surround the first fluid port, and gripping elements may be provided on the shroud.

  • Publication number: 20080300543
    Abstract: An enclosed needle catheter insertion device includes a catheter assembly and a need insertion device having a needle guard housing to enclose a needle in a shielded position and a needle support supporting the needle for movement between a ready position, with the tip of the needle exposed, to a shielded position with the needle within the needle guard housing. Movement of the needle support and the needle relative to the needle guard housing is accomplished by manual manipulation of a gripping component external of the needle guard housing. A separate, proximal end cap external of the needle guard housing encloses a proximal portion of the needle guard housing, and is affixed to the needle support.

  • Publication number: 20080286092
    Abstract: To reduce the noise level of air convective warmer, the air filter of the warmer is fitted with an air intercept mechanism to disrupt the flow of air that traverses inside the interior cavity of the air filter. By thus disrupting the air flow, the noise that otherwise would have been generated due to a non-interrupted air stream flow is lowered. The air intercept mechanism may be in the form of at least one partition positioned inside the interior cavity of the air filter. Alternatively, double-ended open tubes may be used, so long as the interior cavity of the filter is sealed, with only the tubes providing the passages for air to output from the air filter. Yet a third embodiment of the air reduction filter has an air impermeable material covering at least one portion of the surface area of the filtering material to prevent the inflow air from directly entering into the interior cavity of the air filter through the covered surface area.

  • Publication number: 20080287887
    Abstract: A pump module for use in a medical fluid dispensing system is provided that includes a pump body and first and second pump chambers formed in the pump body. The module further includes a pair of chamber inlets and chamber outlets formed in the pump body, each associated with one of the pump chambers. Each of the pump chambers further includes a first portion having a generally spherical segment shape and a second portion integral with the first portion and having a generally conical shape, with the first and second portions in fluid communication with the chamber inlet and the chamber outlet. The second, conically shaped portion converges to the chamber outlet.

  • Publication number: 20080287872
    Abstract: A pump module is provided for use in a medical fluid dispensing system that includes a pump body made of a non-compliant material and first and second pump chambers formed in the body. Each of the chambers has a first, open end and an opposite, closed end. The pump module further includes first and second pistons in the first and second pump chambers, respectively. At least one fluid inlet and a fluid outlet are selectively in fluid communication with the first and second pump chambers. Each of the pistons extends through the open end of a respective one of the pump chambers, with each of the pistons being operably translatable within the pump chamber toward and away from the closed end of the chamber. The pistons are translatable independently of one another.

  • Publication number: 20080288034
    Abstract: A convective blanket has multiple sets of discontinuous bonding strips that bond or attach its upper layer to its lower layer to form a number of air flow guides within the blanket. There is at least one set of substantially parallel discontinuous strips proximate to the air input port of the blanket and another set of substantially parallel discontinuous strips remote from the air input port. For each set of in parallel discontinuous bond strips, the respective distal and proximal ends of each successive strips are aligned with the distal and proximal ends of a corresponding substantially in parallel strip to effect a cross channel so that air flowing along the air flow guide may escape to different sections of the blanket. To output the heated air from the blanket, respective single rows of successively spaced air holes are formed adjacent to and substantially along the length of the discontinuous bond strips that are located proximate to the air input port.
