Abstract
A patient access site securement system includes a housing with an inlet, an outlet and an internal fluid path between the inlet and the outlet. The housing also has a connecting portion that connects to a catheter and/or a fluid line attached to the catheter. A contact surface is located on an underside of the housing and positions the patient access site securement system on the patient. A first reservoir with an interior holds a liquid and transitions from a first state to a second state. The interior is in fluid communication with the inlet when the reservoir is in the second state to allow the liquid to flow from the inlet, through the internal fluid path and exit the outlet. The liquid interacts with the contact surface and/or the patient to alter a level of securement between the catheter and the patient.
Core Innovation
The invention relates to a patient access site securement system for securing a catheter and/or a fluid line attached to the catheter to a patient. The system includes a housing with a first inlet, a first outlet, and an internal fluid path between the first inlet and the first outlet, and a connecting portion configured to connect to the catheter and/or the fluid line attached to the catheter. The housing further includes a contact surface located on an underside of the housing and configured to position the patient access site securement system on the patient.
A first reservoir having an interior configured to hold a first liquid is configured to transition from a first state to a second state. When the first reservoir is in the second state, the interior is in fluid communication with the first inlet such that the first liquid flows from the first inlet, through the internal fluid path, and exits the first outlet. The discharged first liquid interacts with the contact surface and/or the patient to alter a level of securement between the catheter and/or the fluid line attached to the catheter and the patient.
The housing includes at least one access element configured to breach at least a portion of the first reservoir when transitioning towards the second state, thereby allowing the first liquid to flow into the first inlet. The disclosed variants and related structures include protective caps to prevent reservoir transition, reservoir breachable portions, and different implementations in which the housing supplies liquids that change securement level by interacting with the contact surface and/or the patient.
Claims Coverage
The document includes two independent claims covering a patient access site securement system and a method for securing a catheter and/or a fluid line using the system. The claims center on four inventive features: a housing with an internal fluid path and connecting portion, an underside contact surface, a first reservoir that transitions between states to deliver a first liquid, and an access element that breaches the reservoir to enable liquid flow into the first inlet.
Housing with internal fluid path and connecting portion
A housing having a first inlet, a first outlet and an internal fluid path between the first inlet and the first outlet, the housing also having a connecting portion configured to connect to the catheter and/or the fluid line attached to the catheter.
Underside contact surface positioning the system on the patient
A contact surface located on an underside of the housing and configured to position the patient access site securement system on the patient.
State-transition first reservoir supplying first liquid through the internal fluid path to alter securement level
A first reservoir having an interior configured to hold a first liquid, the first reservoir configured to transition from a first state to a second state, the interior being in fluid communication with the first inlet when the first reservoir is in the second state to allow the first liquid to flow from the first inlet, through the internal fluid path and exit the first outlet such that the first liquid interacts with the contact surface and/or the patient to alter a level of securement between the catheter and/or the fluid line attached to the catheter and the patient.
Access element breaching the reservoir during transition to allow liquid flow into the inlet
The housing includes at least one access element configured to breach at least a portion of the first reservoir when transitioning towards the second state, thereby allowing the first liquid to flow into the first inlet.
Method using the system with reservoir transition to alter securement level
Providing a patient access site securement system comprising: a housing having a first inlet, a first outlet and an internal fluid path between the first inlet and the first outlet, the housing also having a connecting portion configured to connect to the catheter and/or the fluid line attached to the catheter; a contact surface located on an underside of the housing and configured to position the patient access site securement system on the patient; and a first reservoir having an interior configured to hold a first liquid, the first reservoir configured to transition from a first state to a second state, the interior being in fluid communication with the first inlet when the first reservoir is in the second state to allow the first liquid to flow from the first inlet, through the internal fluid path and exit the first outlet; connecting a catheter and/or a fluid line to the connecting portion of the housing; positioning the contact surface on the patient; transitioning the first reservoir from the first state to the second state, thereby causing the first liquid to interact with the contact surface and/or the patient and alter a level of securement between the catheter and/or the fluid line attached to the catheter and the patient.
Access element breaching the reservoir during the method transition
Wherein the housing includes at least one access element configured to breach at least a portion of the first reservoir when transitioning towards the second state, thereby allowing the first liquid to flow into the first inlet.
Across both independent claims, the coverage is concentrated on the coordinated combination of a housing with an internal fluid path and connecting portion, an underside contact surface for positioning on the patient, a first reservoir transitioning between states to deliver a first liquid through the fluid path so the liquid interacts with the contact surface and/or patient to alter securement level, and an access element that breaches the reservoir to enable the liquid flow into the first inlet.
Stated Advantages
Alters a level of securement between the catheter and/or the fluid line attached to the catheter and the patient.
Documented Applications
Securing a catheter and/or a fluid line attached to the catheter to a patient using a patient access site securement system.
