DESC:Field of Invention
The subject matter of this document is mattress systems, and more specifically, techniques, equipment, and systems for sensing bed or user-related characteristics, such humidity and temperature.
(001)This invention is centred on a body heat reflecting body that includes a heat sensing layer for mattresses, which greatly improves the heat insulation properties. This device captures electromagnetic vibrations when the body's position changes, helping to prevent decubitus ulcers. It consists of various components such as a pipe-like structure, a body, and solenoid, an external system for storing electromagnetic energy, a control unit, and an internal energy source.

Background of the Invention

(001) Bedsores, often called pressure ulcers, are the problem that this technology aims to solve. To prevent the patient's skin from being stressed and developing bedsores, it is recommended to change your position often. "When it Depending on the patient's health, the heat sensor detector will modify their posture anywhere from 15 minutes to 6 hours per hour. People who have been in the hospital for a long period, whether they are old, on trama, comatose, or in critical care, can benefit much from this.
(002)The body's heat insulation can be passive or active, with passive methods focusing on keeping heat within and active methods seeking heat from outside sources. A passive method involves insulating the body through fabric or infrared reflective materials. An active method involves incorporating electric heating, chemical reactions, and solar heat-retaining materials into a tube-like device that generates electromagnetic oscillations during movement. However, this method lacks a second solenoid with an electromagnetic energy storage system and control block.

(003)The prototype consists of a stem-like pipe, a body moving along the pipe channel, a solenoid, an external system for storing electromagnetic energy, and a control block. The body is housed in the interior cavity of the stem-like tube, and the solenoid is linked to the external system through the energy storage system. The control block is connected to the specified external system, allowing the body to detect electromagnetic oscillations in response to changes in body position.

(004)Thermal conductivity is a material-specific constant that indicates the amount of heat transmission within an object. It is influenced by factors like density, specific heat, and viscosity. Metals are valuable due to their free magnetism and heat conduction. To enhance radiation properties, a practical model was added with a solenoid, external electromagnetic energy storage system, and control block. The body with internal electromagnetic energy is connected to the external system through an electromagnetic energy storage system. The body in the inner cavity of the stem-like tube also contains a second solenoid, external electromagnetic energy storage system, control block, and internal energy source. The internal energy source is a resonator-accumulator of electromagnetic energy, and the current flows in the opposite direction of the first solenoid's current. The model consists of a stem-like tube, body for movement along the tube channel, a solenoid, external electromagnetic energy storage system, and control block.
(005)The utility model aims to address limitations in nursing practice by proposing a body position change alarm system that includes a bed frame, an alarm, a two-way threaded rod, and a pressure sensor. The system includes a safeguard outside the bed frame, which includes two buffer plates in the form of an arc. Sliders A and B control the movement of the two arc-shaped buffer plates, which are positioned in the middle of the nursing bed while the bed is in use. This allows the patient to slide down in case of an unintentional fall, increasing their protection from striking the ground.

(006)The utility model also allows the pressure sensor board and gadget to track the patient's location. The patient is equipped with a telescopic rod and a pressure spring, and an alarm is set off to alert the nursing staff in case of the patient's slip from their bed. The telescoping rod and pressure spring work together to make the pressure sensor plate more sensitive to pressure, making the patient safer and more comfortable.

(007)The utility model has several advantages over the state-of-the-art, including ensuring patient safety through the safeguards offered by the system, tracking the patient's Position, and providing a more user-friendly design. However, there are potential issues such as potential degradation of coating appropriateness.

(008)This specification describes a surface position measuring device, consisting of a position sensor, an electrical device, a current detector, a unit that moves and drives the object or position sensor, and a unit that measures the relative amount of movement between the two. The current detection means pick up the current from the field emission, and a position calculation means determines the item's position in relation to the moving amount.

(009)An optimal position measuring sensor uses an elastic mechanism to direct the electrode towards a predetermined position while allowing movement. An arc-shaped elastic metal plate covers the displacement electrode. A voltage source is connected, allowing adjustment of gap.
(008) The displacement electrode is an arc-shaped elastic metal plate covering the measuring electrode's tip. The ideal voltage producing means include an adjustment circuit for gap adjustment, with the distal end shaped like an arc and the center of curvature parallel to the movement drive.
(009)The control means should stop the movement driving means when the current detected by electric field radiation reaches a first set value. The movement amount measuring means should measure the movement from start to stop. If the current detected is less than the first set value, the control means should decrease the speed.
(010)The present specification proposes a position measurement sensor that can measure the surface position of an object. This sensor consists of a measurement electrode and a displacement electrode. The displacement electrode is positioned such that it can generate electric field radiation between the two electrodes when a voltage is applied, and the measurement electrode can then use this radiation to determine the surface position.
Effect of the invention
(011) A mattress is a piece of furniture used for sleeping and relaxing, often featuring a soft mattress on top of the frame. Modern mattresses may include springs, foam materials, and air chambers to support the weight of one or more users. Various features and systems have been used in conjunction with the mattress, including heating and cooling systems and temperature sensors for heating and cooling.

(012)Most existing nursing mattresses are equipped with movable mattress boards to help patients sit up or change lying positions, but most products have a low level of intelligence and are subject to certain restrictions on use. The elderly and disabled who are mattressridden for a long time need a multi-degree-of-freedom, modular robotic nursing mattress system that can realize the functions of a conventional nursing mattress, combine the mattress-chair conversion function, and have a high level of automation and intelligence.

(013)Some embodiments of a mattress system include a sensor strip for sensing parameters of the mattress system and/or a user, such as temperature and humidity values, and a microclimate control system that supplies conditioned air to achieve a desired temperature on top of the mattress. The sensor strip can be easily replaced with another sensor strip for repair and upgrade.

(014)The carrier strip in a mattress system can be configured to releasably attach to the foam layer, with the first surface being configured to releasably attach to the first and second portions of the foam layer. A plurality of first and second sensors may be disposed at the first surface of the carrier strip, and a plurality of first and second sensors may be provided at the second surface. The system may optionally include features such as a mattress cover disposed over the foam layer and covering the foam layer and sensor strips. The sensor strip may be configured to releasable attach to the foam layer without an intermediate surface between the sensor strip and the foam layer, and may include micro hooks or loop fasteners. The top layer may be a compressible material, foam, or fabric. The method may also include features such as a second sensor strip with different types, numbers, and arrangements from the first sensor strip. The system may also include a mattress topper disposed over the foam layer and covering the foam layer and sensor strips.

(015)The sensor strip configuration described in this article provides several advantages to the mattress system. It enhances stability, serviceability, and application by securely attaching the sensor strip to the mattress's top layer using micro hook attachments at the ends. This allows for consistent temperature and humidity values, which can be used to accurately determine temperature trends, user body temperature, desired airflow supply, mattress occupancy, and user sleep position.

(016)Additionally, the sensor strip configuration makes it easier and faster to remove the entire sensor strip from the mattress system, as all sensors can be attached in series, making the repair process faster and less invasive. The sensor strip can be easily attached to any mattress or mattress system using micro hook attachments at each end, ensuring no movement of the sensor strips.

(017)Another advantage is providing different airflow supplies to different parts of the mattress system. For example, in a king-size mattress system, the sensor strip may include a plurality of first sensors and a plurality of second sensors, with each sensor positioned over each air chamber.

(018)In conclusion, the sensor strip configuration provides personalized management of airflow through the mattress, providing more accurate temperature and humidity readings, better airflow supply, and more comfortable sleeping conditions for users.
