Embodiment 1

[0011] see figure 1 , the intelligent anti-pressure sore nursing pad of the present invention is composed of a foam dressing 1, a composite film 2, an array distributed flexible film pressure sensor 3, a polymer chip module 4, a lithium battery 5, a PE waterproof film 6, and a charger 7 , a total of four layers, the surface layer is a replaceable foam dressing 1, the second layer is a diaper-grade composite film 2, which is breathable from top to bottom, and the third layer is an array distributed flexible film pressure sensor 3, which is connected to a polymer chip module 4 and a high-energy The miniaturized lithium battery 5, the fourth layer, the bottom layer, is a PE waterproof film 6, and the charger 7 is an accessory. The periphery of the four-layer film is pressed together tightly, and the size of the entire nursing pad is set to 45cm*60cm.

[0012] Foam dressing 1 is a dressing made of water molecular materials, covered with a layer of polyurethane semi-permeable memb...

Embodiment 2

[0018] When in use, the nursing pad is placed on the part of the patient that is prone to pressure sores. The array distributed flexible film pressure sensor in the nursing pad will measure the pressure statically and dynamically after receiving the pressure. The resistance decreases as the pressure increases. Its piezoresistive characteristics are represented by a power function relationship between resistance and pressure, and an approximately linear relationship between the reciprocal of resistance and pressure, and then transmit data to the mobile terminal in real time and stably through the polymer chip module, and send a warning signal to the mobile terminal when the pressure is ≥ 9.3kPa . The mobile terminal (such as: mobile phone, computer, etc.) used by the nursing staff can download the matching software to monitor the pressure of the pressure part in real time. When the pressure of the pressure part of the patient is too high, the nursing staff will receive a warning...

Abstract

The invention provides an intelligent pressure-sore-preventing nursing mat. The intelligent pressure-sore-preventing nursing mat is composed of a surface-layer foam dressing, a second-layer compositefilm, a third-layer array-distributed flexible film pressure sensor, a polymer chip module, a lithium battery, a fourth-layer PE waterproof film and a charger. The peripheries of the four-layer filmsare pressed to tightly fit one another. The intelligent pressure-sore-preventing nursing mat is designed aiming at solving the problem that when a caregiver nurses a patient susceptible to pressure sore simply by experience, the incidence rate of the pressure sore is high; the pressure of a pressed part can be monitored in real time and stably transmitted to a mobile terminal, when the pressed part is subjected to excessive pressure or is pressed for too much time, caution information can be sent to the mobile terminal through a set program, and therefore, the body position of the patient is changed to relieve local pressure; the content of pressure-sore preventive nursing is perfected, personalized nursing is ensured, the incidence of the pressure core is reduced, and pain of the patientis avoided. The intelligent pressure-sore-preventing nursing mat is reasonable in design, operation of the caregiver is simple, the mat is comfortable for the patient to use, and unnecessary medical costs are reduced.

Description

technical field [0001] The invention belongs to medical auxiliary devices, and relates to an intelligent anti-pressure sore nursing pad. Background technique [0002] A pressure sore is a pressure injury, which is a localized injury to the skin and soft tissue under the bony prominence, medical equipment, and other equipment under the combined action of pressure or pressure combined with shear force. Can present as intact skin or open sores, which may be painful. Severe stage 4 pressure injury skin can present as a full-thickness wound with loss of full-thickness skin tissue with exposure of bone, tendon, or muscle. Necrotic tissue exfoliation or eschar may appear locally. The occurrence of pressure sores is the result of a combination of factors. Pressure sore assessment scale: Braden Scale (Braden Scale) suggests that risk factors for pressure sores include sensation, mobility, activity patterns, nutrition, moisture, and friction. Pressure is the most important factor i...
