Description

Technical Field

[0002] For patients with dysphagia, the nature of food has a great impact on whether the patient can eat smoothly. The clinical classification standards are as follows:

[0003] The specific classification standards for liquid food are as follows: Level 1 low-viscosity type: The specific characteristics are described as follows: it spreads in the mouth when entering, and does not require much force when swallowing, which is suitable for patients with mild swallowing disorders; it is easy to flow out of the spoon in a line when the spoon is tilted, and the word "sucking" is the most appropriate expression;

[0004] The specific properties of the secondary medium-thick type are as follows: it slowly spreads in the mouth and easily gathers on the tongue, and is suitable for patients who have just started oral therapy. It can drip out of the spoon when scooped up and tilted, and the expression "drink" is the most appropriate.

[0005] The specific characteristics of the third-level high-viscosity type are as follows: it is obviously sticky and requires a certain amount of force to be put into the throat, which is suitable for patients with severe dysphagia; it is lumpy when scooped up with a spoon and tilted, and will not flow down immediately, so the most appropriate expression is "eat";

[0006] The specific solid food classification standards are as follows: Level 4 fine mud type: The specific characteristics are described as: homogeneous, smooth, easy to gather, can be scooped up with a spoon, can form a food ball through the mouth, easy to swallow, not easy to remain in the oropharynx or aspirate; for example, it can be swallowed without biting or chewing, and various homogeneous paste foods that are mixed by a blender after adding food function regulators; suitable for those who do not need chewing ability but need to have the ability to transport food and can eat orally; the whole spoonful of food will slide out when the spoon is tilted;

[0007] The specific characteristics of the fifth-level fine filling type are described as: having a certain shape, but easy to crush, having a certain degree of cohesion, easy to form a food mass, not leaving the mouth in large quantities, not easy to disperse in the pharynx, and can be crushed between the tongue and the upper and lower jaws; for example, food made by adding food functional regulators and stirring, such as three-point porridge, five-point porridge and various soft foods; suitable for objects that can be crushed by the tongue and the upper and lower jaws, and food can be transported by the tongue; the shape can be maintained on the spoon, and when the spoon is tilted downward or sideways or slightly shaken, the whole spoonful of food will slide down, and it can form a mass or slowly collapse on the plate;

[0008] The specific characteristics of the sixth-level soft food type are described as: soft, not easy to disperse, not easy to stick, the hardness can be cut with chopsticks or spoon, and can be swallowed without teeth or dentures, but requires the ability to be crushed between the upper and lower gums; for example, soft food and liquid food are mainly foods, such as whole porridge, soft rice, and stirred foods with higher hardness; suitable for people with decreased swallowing and chewing functions who are at risk of aspiration; the edge of the spoon can be used to cut or divide the food into small pieces, and the food can be flattened when a small piece of food is pressed down with the head of the spoon. If the spoon is removed, the food will not return to its original shape.
