Abstract:
A safety catheter includes a catheter hub (16), a catheter tube (18), a needle hub (20), a needle cannula (22) having a distal tip (24), and a tip protector (30). The tip protector (30) includes an outer member (34) having a flexible tab (130) configured to releasably engage with the catheter hub (16) and release therefrom upon inward flexing of the tab (130). An inner member (32) is positioned entirely within the outer member (34) and has a portion (64) that impedes inward flexing of the tab (130) when disposed adjacent thereto. The inner member (32) is axially shiftable relative to the outer member (32) between a first position wherein the needle tip (22) is distal of the tip protector (30) and the inner member portion (64) is disposed adjacent the tab (130) to impede release from the catheter hub (16), and a second position wherein the tip (22) is within the outer member (34) and the inner member portion (64) is no longer adjacent the tab (130) and no longer impedes release from the catheter hub (16).
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.
Abstract:
An ambulatory infusion pump can include a guided user help system that allows for a user to correct an error with the pump without needing to summon a home healthcare aide or other medical professional. When an error occurs with the pump, the user can select an option to receive help with the error. The help screen can display a possible solution for correcting the error that the user can follow. Additional help screens can display additional possible solutions if prior possible solution prove ineffective at correcting the problem.
Abstract:
A connector assembly for a heat exchanger has a fitting and a mount to which the fitting couples. The fitting has an elongate body having a proximal portion and a distal portion. At the proximal portion there is a crossbar, and at the distal portion there are an inlet and an outlet that protrude away from the body. Two wings extend from the body in a direction opposite to that of the inlet and outlet. There is formed on each of the wings a locking protrusion. The mount has a top portion where there is a groove dimensioned to accept the crossbar of the fitting. A longitudinal channel is formed orthogonal to the groove in the mount. Two sidewalls extend from the mount each for accepting a corresponding one of the wings, when the fitting is coupled to the mount. Apertures are provided at the sidewalls to engage the protrusion at the wings so that, once the fitting is coupled to the mount, it is secured thereto, until a force is exerted to compress the wings towards each other to disengage the protrusions from the apertures. To couple the fitting to the mount, a user first positions the crossbar of the fitting onto the groove of the mount, with the body of the fitting at an angle relative to the mount. With the crossbar resting on the groove, a pivot point is established between the fitting and the mount, so that the body of the fitting can be pivotally positioned within the channel of the mount. At that time the inlet and outlet of the fitting are mated to an output port and an input port, respectively, of the mount; and the protrusions at the wings of the fitting are engaged to the apertures at the sidewalls of the mount. An infusate line and a heat exchanger are connected to the proximal end and distal end, respectively, of the fitting.

Abstract:
A convective warming blanket has a head portion and a plurality of peripheral sections extending orthogonally from each side of a central section that extends uninterrupted from a proximal end below the head portion to a distal foot end of the blanket. Each peripheral section is separable from its adjacent peripheral section by a frangible or tearable common seal. At least one through passage connects each peripheral section to the central section, so that the peripheral sections are inflated when heated air is input to the blanket. The multiple peripheral sections each are movable relative to the central section, so that different body parts of the patient may be selectively accessed. The head portion of the blanket is formed by two tubular sections that extend from the proximal portion of the blanket to encircle the head of the patient, when the blanket is placed over the patient.
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:
A full body blanket has a central bonded strip that extends from a distal end of an upper portion of the blanket to the foot end of the blanket to divide the main body of the blanket into two longitudinal portions. A discontinuous slit or tearable line is provided along the length of the strip to enable the longitudinal portions to be separable from each other by a user applying a force along the tearable strip. The strip may be torn anywhere along its entire length so that the longitudinal portion to be removed from the patient may be folded back anywhere along the length of the strip to selectively expose particular body parts of the patient. The blanket is inflated by heated air, and the heated air is circulated by channels that extend longitudinally along each of the longitudinal portions. Rows of apertures provided along the channels at the layer of the blanket that makes contact with the patient output the heated air to warm the patient.
Abstract:
A convective warming blanket is configured to have an upper body portion and two leg portions that extend from a distal end of the upper body portion. The leg portions are separated by a space sufficient to expose a lateral side of a patient covered by the blanket. A flap separable from the leg portion that extends from the mid-section of the upper body portion may be used to securely wrap around the extended arms of the patient, who is lying on his side. Adhesive tapes are provided on the outside edges of the leg portions to secure the blanket to the surface onto which the patient lies. Apertures are appropriately formed at the sheet that comes into contact with the patient at the upper body portion and along the respective inner side edges of the leg portions so that both the upper body and the exposed lower body of the patient are warmed by heated air. The blanket is designed to have mirror image versions usable for exposing the lateral left side or the lateral right side of the patient.
Abstract:
A heat exchanger has a multi-lumen tubing having one end connected to a supply fitting and another end connected to a return fitting. The tubing has a central lumen, a middle lumen that surrounds the central lumen and an outer lumen that surrounds the middle lumen. The supply fitting has an inlet, an outlet and a proximal port wherethrough an infusate is input to the heat exchanger. The supply fitting is configured such that its inlet is connected to the central lumen, its outlet connected to the outer lumen, and its proximal port connected to the middle lumen of the tubing. The return fitting is configured to establish a through passage between the central lumen and the outer lumen of the tubing so that a heating fluid fed through the supply fitting to the central lumen is returned to the supply fitting by way of the outer lumen. The return fitting further has a distal port configured to connect to the central lumen of the tubing, so that the infusate fed to the proximal port of the supply fitting may be output from the distal port of the return fitting, after passing through the central lumen of the tubing. As the infusate traverses along the heat exchanger, it is heated by the heating fluid that flows along the central lumen, and also by the rerouted heating fluid that flows along the outer lumen of the tubing. The heat exchanger is fluidly coupled to a heater by its inlet and outlet so that the temperature of the heating fluid for warming the infusate is maintained at a predetermined temperature.
