Problems solved by technology

[0017] The causes of pressure sores
[0018] 1. Partial long-term pressure without changing body position for a long time, resulting in blood circulation disorder
[0019] 2. The skin is often stimulated by moisture and friction, such as incontinence, debris on the folds of the bed sheet
[0020] 3. Malnutrition throughout the body or insufficient blood supply to local tissues and reduced disease prevention capabilities can easily lead to pressure sores
[0021] 4. The use of plaster bandages and splints is improperly lined, tight and uncomfortable, resulting in blood circulation disorders
[0058] This application provides an anti-pressure sore gasket that can solve the above problems, and replace traditional clinical care with complex, difficult prevention, high cost of use, and difficult-to-observe nursing methods

Embodiment 1

[0104] An anti-pressure sore gasket, the composition and parts by weight are as follows:

[0105]

[0106] The specific preparation is as follows:

[0107] (1) Weigh each raw material according to the above ratio, and then put it in a mixer, mix it at 60-90°C for 30-50 minutes, and let the ratio raw materials mix with each other evenly;

[0108] ⑵Put the material mixed evenly in step ⑴ into the granulator for calendering. The temperature of the molding machine is controlled as follows: first stage: 130-150°C, second stage: 170-200°C, third and fourth stage: 220-240°C , Five and six stages: 210-230°C, each stage is 1-10min, and the thermoplastic composition is obtained after the rolling is completed.

[0109] ⑶ Pass the thermoplastic composition through calendering equipment and injection molding equipment to complete the required shape and size of the product.

Embodiment 2

[0111] An anti-pressure sore gasket, the composition and parts by weight are as follows:

[0112]

[0113] Key product characteristics of the anti-pressure sore gasket provided by the present invention (both embodiment 1 and embodiment 2 meet the requirements)

[0114] ⑴Hardness range: Shore A 0-95.

[0115] ⑵Using temperature performance: It can be processed at high temperature. It has good temperature resistance, its embrittlement temperature ≤ -60°C, the highest operating temperature reaches 149°C, and its decomposition temperature is greater than 270°C in an oxygen atmosphere.

[0116] ⑶ Aging resistance performance: the decline rate of performance is less than 10% after aging in an artificial accelerated aging box for one week, and the performance decline rate is less than 10% after 100 hours of ozone aging (38°C).

[0117] ⑷Environmentally friendly performance: Thermoplastic polymers can be used without vulcanization, which meets environmental protection requirements...

Abstract

The invention relates to a pressure sore prevention gasket. The pressure sore prevention gasket is prepared from the following components in parts by weight: a polystyrene-polrvinyl-polybutylene-1-polystyrene linear copolymer, paraffin-base oil, petroleum resin, alpha-vinyltoluene, an antioxidant, a light stabilizer, an antistatic agent and an assistant, wherein the components are formed and extruded after blended. The pressure sore prevention gasket provided by the invention has the characteristics of high high-temperature creep property, high heat aging resistance, high adhesion, high oil resistance, high transparency, high elasticity, high tear resistance and low cost, and is high in physical and mechanical properties and technical processing performance. Due to the characteristic that the pressure sore prevention gasket is recyclable, the disadvantage that thermosetting high molecular materials are difficult to recycle and reuse is eliminated, and the environment is protected.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to a highly transparent, highly viscous, highly flexible and highly stretchable anti-pressure sore gasket. Background technique [0002] 1. Pressure sores (pressure sores, bedsores, pressure ulcers - PU Pressure Ulcer / Presure Sores) [0003] Pressure sores are caused by long-term pressure on local tissues, resulting in persistent ischemia, hypoxia, and malnutrition, resulting in tissue ulceration and necrosis. According to the 2007 NPUAP (National Pressure Ulcer Advisory Panel) new definition of pressure sore: localized damage to the skin and subcutaneous tissue due to pressure, or combined with shear force and / or friction, at the protrusion of the bony prominence. Once bed sores occur, it will not only increase the pain of the patient, prolong the recovery time, but also cause sepsis due to secondary infection in severe cases, and even endanger life. According to relate...
