Mattress for enabling uniform stressing of all parts of human body and method thereof for generating uniform supporting force

Abstract

The invention discloses a mattress for enabling uniform stressing of all parts of a human body lying on a bed and keeping a normal physiological curve and a method of the mattress for generating a supporting force. A bed net of the mattress comprises a plurality of independent piston mechanisms and a sealed air chamber, wherein the piston mechanisms are vertically arranged in parallel; the sealed air chamber is located below the piston mechanisms, communicated with the piston mechanisms and filled with gas having a certain mass; the lower end of a piston cylinder in each piston mechanism is communicated with the sealed air chamber; a piston head of each piston mechanism is fixed on the upper end of a piston rod and connected with a human body or a mattress fabric; after the piston head is pressed, the piston rod can move downwards in the piston cylinder; after pressure applied to the piston head is released, the piston rod can move upwards in the piston cylinder under the action of air pressure of the sealed air chamber; the piston head and the piston cylinder are slidably and hermetically connected; piston cylinders of all the piston mechanisms are mounted on a bracket connected with the wall of the sealed air chamber. The mattress has good breathability, and can be used for ensuring that a person acquires a normal human body physiological curve regardless of the sleeping posture and avoiding poor blood circulation of the person.

Description

technical field [0001] The invention relates to an elastic mattress, in particular to a mattress which makes the supporting force of a person lying on the bed uniform and a method for generating the supporting force. Background technique [0002] A really good mattress must meet at least three criteria: 1) It has good air permeability; 2) No matter what sleeping position the person lying on the bed is in, it can maintain the normal physiological curve of the human body; 3) It can truly Evenly support all parts of the human body, effectively disperse the weight of each part of the human body, and avoid excessive pressure on parts of the body that may cause poor blood circulation. [0003] Most of the mattresses in the prior art can only meet the first standard mentioned above, and a small part can meet the first two standards mentioned above at the same time, but can really meet all the aforementioned standards or the third standard mentioned above. .

Problems solved by technology

[0004] Chinese Invention Patent No. 96204818.6 "Independent Dense Enclosed Plunger Spring Mattress" introduces a kind of independent plunger spring mattress. Since the elasticity of each spring is determined, when a person sleeps on the mattress When the weight force is high, the reaction force received by the part of the body with heavy weight is large, and the reaction force received by the part with low gravity is small. The place with large reaction force is easy to cause compression on local muscles and nerves, so it is difficult to meet the aforementioned requirements. three standards

[0005] Air mattresses or water mattresses are common: 1) Too soft and easy to cause people to sink in the deep pocket of the mattress, that is, the center of the mattress is low and the surroundings are high due to the pressure of body weight. This situation is caused by air or water bags (bags) ) surface tension, the forces on various parts of the human body are not balanced, which not only increases the muscle tension on the lower back and other sides, but also inevitably leads to the relative elevation of the head and neck. This will lead to local muscle tension. Ligament imbalance, which directly affects the normal physiological curve of the human body

2) The air or water bag (bag) is in close contact with the human body, and the air permeability is not good enough

3) The air or water bag (bag) is not effectively blocked or protected, and it is easy to be pierced by sharp tools, which is not safe

4) The water bed is also prone to fluctuations and dizziness, and the water quality is cold, so it is not suitable for people with weak constitutions to use for a long time

[0006] The applicant's previous Chinese utility model patent (Patent No. ZL200520058319.6, titled "Button Mattress") can relatively meet the above three standards, but it is not enough to use physics knowledge to explain It is clear, and there are some defects in the specific implementation as follows:

[0009] 3) Under the action of the gravity of the human body, the contact key of the corresponding part moves downward and compresses the corresponding air column filled with gas downward. Since all the air columns are connected as one, some air columns are compressed and dropped It will pull the adjacent air column downwards to separate the corresponding contact key from the human body, failing to achieve uniform support along the normal physiological curve of the human body

[0010] 4) The manufacture of the inflatable cushion is very difficult
