Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically relates to a low-temperature thermoplastic composite resin pillow and a preparation method and application thereof. Background Art

[0002] Sleep, like diet and exercise, is the most basic physiological need of human beings. As a common cyclical physiological phenomenon, it can maintain the normal growth and development of the body, ensure adequate sleep, accumulate energy for the body, restore physical strength, and allow the brain to get enough rest, protect brain function, and maintain the body's normal immune balance. Sleep is vital for everyone. Different individuals may have different sleep conditions. Long-term lack of sleep will bring some physical and mental changes, such as anxiety, depression, obesity, and poor mental state.

[0003] As an important tool that affects sleep quality, the importance of pillows is mainly reflected in the following aspects: (1) Supporting the head and neck: pillows can provide support for the head and neck, help maintain the natural curvature of the cervical spine, maintain the natural posture of the neck, avoid excessive bending or extension of the neck, and thus reduce the pressure on the neck and shoulders; (2) Improving sleep quality: a suitable pillow can not only provide comfort and support, but also reduce muscle and nerve compression, help people fall asleep more easily, and maintain a healthy sleeping posture, thereby improving sleep quality; (3) Promoting blood circulation: pillows help keep the head and heart at the same height, reduce pressure on the neck and head blood vessels, and maintain good blood circulation; (4) Preventing gastroesophageal reflux. For people with symptoms of gastroesophageal reflux, the proper use of pillows can reduce the possibility of food and gastric acid reflux into the esophagus; (5) Improving respiratory patency: pillows can maintain a certain angle of the upper body, which is conducive to the smooth flow of the airway and prevent the tongue from falling back and blocking the airway when lying flat, which is especially beneficial for patients with snoring or sleep apnea syndrome.

[0004] In order to meet the market demand, memory pillows came into being. Memory pillows refer to pillows with rebound function, which are filled with hollow shaping blocks of silicone or polyurethane. Because of their soft texture, they can gradually form the inherent shape of the head and neck, which can play a certain protective role on the cervical spine. However, this type of pillow requires a long time to shape to fit the curvature of the cervical spine, and there is a certain degree of discomfort during the shaping process. At the same time, the shaping process of this type of pillow is completely based on the user's sleeping posture. If the user's sleeping posture is not good, the shaping will not be effective for the patient's sleep improvement, and it is difficult to adjust once the shaping is completed. Summary of the invention

[0005] The present invention is aimed at the defects of the current use of memory pillows and provides a low-temperature thermoplastic composite resin pillow and a preparation method and application thereof. The pillow can be softened at 45-70°C for shaping adjustment and hardened below 45°C. Under the intervention of a sleep monitoring system and a physician, multiple adjustments can be made in a targeted manner, which is helpful to alleviate various sleep disorders.

[0006] The first aspect of the present invention provides a low-temperature thermoplastic composite resin pillow, comprising the following components in the following mass percentages: 40% to 50% polyurethane, 35% to 40% caprolactone, and 5% to 10% nylon.

[0007] Polyurethane is a common material for memory pillows, but it can only be thermoplastic at temperatures above 100°C. Adding caprolactone helps increase the low-temperature thermoplasticity of the composite resin, and can increase the thermoplasticity of the resin within a temperature that is comfortable for the human body; adding nylon resin helps to enhance the rigidity of the composite resin. By adjusting the composite resin formula, the softening temperature point of the composite resin can be adjusted. It softens in the temperature range of 45 to 70°C, hardens below 45°C, and maintains a suitable hardness.

[0008] Further preferably, a carbon nanotube film interlayer is provided in the low-temperature thermoplastic composite resin pillow of the present invention. The carbon nanotube film interlayer is laid in the composite resin and has a thickness of 5 to 20 microns, and can be deformed completely according to the plastic changes of the composite resin.

[0009] When the carbon nanotube film interlayer is electrified, the carbon nanotube emits far infrared rays, which irradiate a human body sleeping on the pillow, thus playing an infrared physiotherapy role.

[0010] The second aspect of the present invention provides a method for preparing the low-temperature thermoplastic composite resin pillow described above, comprising the following steps:

[0011] A. Preparation of rectangular composite resin blocks

[0012] Polyurethane, caprolactone and nylon are mixed in predetermined amounts and stirred evenly at high speed, then injected into a rectangular mold, and a carbon nanotube film interlayer is embedded therein, and a foaming initiator and a foaming agent are added to foam freely, and after the foaming reaction is completed, a rectangular composite resin block can be formed;

[0013] B. Pillow Preparation

[0014] After the rectangular composite resin block is heated and softened at 45 to 70 degrees Celsius, the user lies on it, and the composite resin block is shaped according to the user's head and neck shape. After the shaping is completed, the heating is stopped, and the resin module cools and solidifies to form a personalized resin pillow.

[0015] In the preparation process of the present invention, the resin foaming is self-foaming at room temperature, and the foaming agent is selected from any one or more of environmentally friendly foaming agents, water-decomposing foaming agents, active hydrogen foaming agents, and non-ionic surfactant type foaming agents.

[0016] Among them, environmentally friendly foaming agents are a type of foaming agent that does not contain fluorine and does not harm human health and the environment, represented by water vapor, alkyl ethers and aliphatic alcohols; water-decomposable foaming agents are a type of compound containing functional groups such as carboxylic acids, amides, and ureas. Their characteristic is that the foaming process mainly depends on the water decomposition reaction, and can produce a large volume expansion rate and low-density polyurethane foam; active hydrogen foaming agents are a type of compound containing an active hydrogen structure, such as polyether polyols, polydimethylsiloxanes, etc., and their foaming reaction is mainly to react with isocyanates to form polyurethane, gradually producing bubbles; non-ionic surfactant type foaming agents are a type of compound including fatty alcohols, polyoxides, dimers, etc., and the foam they form is delicate, uniform, and has good compression resistance.

[0017] In order to control the progress of foaming, regulators may also be added, such as plasticizers, catalysts, stabilizers, emulsifiers, etc. These additives can promote the foaming reaction, improve the foaming performance, increase the foaming speed, etc., thereby achieving the effect of regulating the foaming speed of polyurethane.

[0018] Further preferably, in step B, the pillow shape can be adjusted by using AI optimization or in combination with the professional diagnosis of a neurologist: when using AI optimization, the deep sleep time of composite resin pillows of different shapes is recorded, the relationship between deep sleep time and pillow shape is constructed, and the pillow shape is adjusted through AI machine learning. When adjusting in combination with the doctor's professional judgment, the user's sleep parameters are detected by polysomnography or a smart bracelet, and the pillow parameters are manually adjusted based on the doctor's analysis of the parameters.

[0019] In a third aspect, the present invention provides a system for optimizing deep sleep, comprising the low-temperature thermoplastic composite resin pillow, a sleep recording system, and a pillow adjustment system. The sleep recording system is used to record various sleep parameters of the user when sleeping on pillows of different shapes, such as using a polysomnography system; the pillow adjustment system selects an artificial neural network to learn the sleep analysis results and pillow shape parameters under different test conditions, and analyzes the pillow shape based on the learning results.

[0020] Functions and Effects of the Invention

[0021] The present invention provides a low-temperature thermoplastic composite resin pillow and a preparation method and application thereof. The formula of the composite resin is first adjusted so that the pillow has low-temperature softening performance and can be softened between 45 and 70°C. The human body feels better in this temperature range, which is conducive to the smooth shaping of the pillow. At the same time, the pillow hardens at 45°C and maintains a certain rigidity, effectively preventing the pillow from deforming at high temperature.

[0022] Furthermore, the preparation process of the pillow of the present invention is simple, and the foaming molding can be completed at room temperature without complicated process steps. At the same time, during the shape adjustment process of the pillow of the present invention, the shape of the pillow can be adjusted in combination with AI optimization or the professional diagnosis of a neurologist, so as to achieve the specific design of the pillow shape for each user, which is more helpful for improving the sleep quality of the user and can be used as an auxiliary treatment for certain sleep disorders.

[0028] The low-temperature thermoplastic composite resin pillow formula of this embodiment includes the following components in the following mass percentages: 40% to 50% polyurethane, 35% to 40% caprolactone, and 5% to 10% nylon. Since additives need to be added, the sum of the three masses should be less than 100%, such as 50% polyurethane, 40% caprolactone, 9% nylon, and the rest is additives.

[0029] Furthermore, a carbon nanotube film interlayer is also provided in the low-temperature thermoplastic composite resin pillow of this embodiment. The carbon nanotube film interlayer is laid in the composite resin and has a thickness of 5 to 20 microns. The thickness can be deformed completely according to the plastic changes of the composite resin.

[0030] The carbon nanotube film interlayer provides a therapeutic effect. When powered on, the carbon nanotubes emit far-infrared rays, which irradiate the human body sleeping on the pillow and play an infrared therapeutic role.

[0032] A. Preparation of rectangular composite resin blocks

[0033] Polyurethane, caprolactone and nylon are mixed in predetermined amounts and stirred evenly at high speed, then injected into a rectangular mold, and a carbon nanotube film interlayer is embedded. After adding a foaming initiator and a foaming agent, they are freely foamed. After the foaming reaction is completed, a rectangular composite resin block can be formed.

[0034] The resin foaming is self-foaming at room temperature, and the foaming agent is selected from any one or more of environmentally friendly foaming agents, water-decomposition foaming agents, active hydrogen foaming agents, and non-ionic surfactant type foaming agents.

[0035] Specifically, environmentally friendly foaming agents are a type of foaming agent that does not contain fluorine and does not harm human health and the environment, and are represented by water vapor, alkyl ethers, and aliphatic alcohols; water-decomposable foaming agents are a type of compound containing functional groups such as carboxylic acids, amides, and ureas, and are characterized in that the foaming process mainly relies on water decomposition reactions, and can produce a large volume expansion rate and low-density polyurethane foam; active hydrogen foaming agents are a type of compound containing an active hydrogen structure, such as polyether polyols, polydimethylsiloxanes, etc., and their foaming reaction is mainly to react with isocyanates to form polyurethanes, and gradually produce bubbles; non-ionic surfactant type foaming agents are a type of compound including fatty alcohols, polyoxides, dimers, etc., and the foams they form are delicate, uniform, and have good compression resistance.

[0036] In order to control the progress of foaming, regulators may also be added, such as plasticizers, catalysts, stabilizers, emulsifiers, etc. These additives can promote the foaming reaction, improve the foaming performance, increase the foaming speed, etc., thereby achieving the effect of regulating the foaming speed of polyurethane.

[0037] B. Pillow Preparation

After the shaping is completed, the heating is stopped, and the resin module cools and solidifies to form a personalized resin pillow.

[0039] C. Shaping and adjustment

[0040] Use AI optimization or combine with the professional diagnosis of neurologists to adjust the shape of the pillow: When using AI optimization, record the deep sleep time of composite resin pillows of different shapes, build the relationship between deep sleep time and pillow shape, and adjust the pillow shape through AI machine learning. Specifically, monitor NREM (light sleep + deep sleep) and REM through polysomnography (PSG), use artificial neural network for AI learning, and through learning a large amount of test data, AI can find the pillow shape that prolongs deep sleep time, and then fine-tune the pillow based on the shape parameters.

[0041] When making adjustments based on the doctor's professional judgment, the user's sleep parameters are detected through polysomnography or a smart bracelet, and the pillow parameters are manually adjusted based on the doctor's analysis results and improvement suggestions.

[0042] Based on the above analysis, the present invention provides a system for optimizing deep sleep. Figure 2 , including the low-temperature thermoplastic composite resin pillow, sleep recording system, and pillow adjustment system described above. Among them, the sleep recording system is used to record various sleep parameters of users when sleeping on pillows of different shapes, such as using a polysomnography monitoring system; the pillow adjustment system selects an artificial neural network to learn and record the sleep analysis results and pillow shape parameters under different test conditions, and construct a mathematical model of the relationship between deep sleep time and pillow shape.
