Abstract
A multi-parameter patient monitoring device rack can dock a plurality of patient monitor modules and can communicate with a separate display unit. A signal processing unit can be incorporated into the device rack. A graphics processing unit can be attached to the display unit. The device rack and the graphic display unit can have improved heat dissipation and drip-proof features. The multi-parameter patient monitoring device rack can provide interchangeability and versatility to a multi-parameter patient monitoring system by allowing use of different display units and monitoring of different combinations of parameters. A dual-use patient monitor module can have its own display unit configured for displaying one or more parameters when used as a stand-alone device, and can be docked into the device rack when a handle on the module is folded down.
Core Innovation
The invention described addresses multi-parameter patient monitoring through a modular device rack capable of docking multiple patient monitor modules and communicating with a separate display unit. By incorporating a signal processing unit into the rack and attaching a graphics processing unit to the display unit, the system achieves improved heat dissipation and drip-proof capabilities. This modular architecture affords interchangeability and versatility, permitting the use of various display units and combinations of monitored parameters.
The background highlights problems with current systems, such as inadequate heat management, susceptibility to contamination from hospital liquids, bulkiness, lack of flexibility in module docking and sensor compatibility, and insufficient portability due to limitations in module form factors. Traditional systems often integrate signal and graphics processing in a single housing, creating heat buildup and requiring large, noisy fans that may be vulnerable to environmental hazards.
The invention solves these issues by decoupling the signal and graphics processing hardware into separate housings with vent and drip-proof designs, enabling effective independent cooling and reducing exposure to liquid ingress. Additionally, a dual-use patient monitor module is introduced: it features a foldable handle and a personal display for stand-alone operation, while remaining compatible with rack docking when the handle is retracted. This design allows customization based on patient acuity and setting, supporting both high-parameter and portable configurations within a unified, modular monitoring platform.
Claims Coverage
The independent claim covers one main inventive feature centered on a modular, portable patient monitoring device with a specific structural housing for heat management and flexible use.
Modular monitoring device with distinct housing portions and ergonomic handle
The device comprises a display unit with a screen and one or more processors designed to wirelessly receive physiological data and output multiple physiological parameters for display. It features a housing divided into a first portion (containing the display unit with a first rectangular footprint) and a second portion extending from the back of the first, where the second portion has a sloped side wall, resulting in a second rectangular footprint that is smaller than the first at its most distant point. This second portion also accommodates inventive airflow design for heat dissipation. A handle extends from the housing to facilitate ergonomic portability.
The inventive feature centers on a modular patient monitoring device with a dual-section housing tailored for improved heat management and portability, supporting wireless data input, ergonomic handling, and structured for multi-parameter physiological monitoring.
Stated Advantages
The modular architecture provides interchangeability and versatility by allowing different combinations of patient monitor modules and display units.
Improved heat dissipation is achieved by separating signal and graphics processing units and incorporating specialized vent and drip-proof features in both rack and display unit housings.
Drip-proof design and placement of vent openings reduce the likelihood of liquid ingress, enhancing safety in hospital environments.
Portable and customizable system supports both fixed and mobile configurations, adapting to various clinical and patient needs.
Compatibility with third-party modules expands the range of measurable physiological parameters and reduces costs for healthcare providers.
Dual-use modules with foldable handles improve ergonomics and transportability without sacrificing rack compatibility.
Documented Applications
Use in low acuity clinical settings such as step-down units, emergency centers, and surgery centers for basic physiological parameter monitoring.
Application in high acuity settings including neonatal ICU, medical ICU, cardiothoracic ICU, and neuro and trauma ICU, supporting extensive multi-parameter monitoring.
Integration with wearable patient monitoring devices and wireless communication for remote parameter display.
