Embodiment 1

[0060] Straight parts

[0061] A straight piece is a straight fabric piece of equal width that can be made from elastic webbing. Elastic webbing is a belt-shaped fabric with certain elasticity, width and thickness that is woven and formed by a machine. The yarn materials used include but are not limited to: spandex, nylon, cotton yarn, polyester, Tetoron, PP polypropylene, silk, etc. Mechanical punching or ultrasonic punching, or high-frequency wave fusion cutting edge sealing process cuts the above-mentioned rolled elastic webbing to make a straight part with a certain length and a specific end edge shape.

[0062] The straight part can also be made of one or more than one kind of fabric with or without edge banding, and the optional straight part is made of a composite fabric made of three or more materials, with a thickness of 1mm-10mm, the width is 5mm-50mm, and the width is often selected within the range of 8mm-30mm. The main strap and the three-dimensional head strap c...

Embodiment 2

[0071] Main strap made of the above straight parts

[0072] 1. The main strap composed of a straight part: bend a straight part into a three-dimensional ring, oval or crown that conforms to the basic shape of the back of the head with an open lower end to form the main strap;

[0073] 2. The main strap composed of two straight parts: connect the two straight parts together by splicing, sewing or hemming the oblique edges of the two straight parts whose ends are cut with oblique lines and rounded corners , forming a three-dimensional annular, oval or coronal main strap with an open lower end conforming to the basic shape of the back of the head with an included angle range of 150°-179°. These two straight parts constitute the left side of the main strap respectively. main strap and right main strap;

[0074] 3. The main strap composed of three straight parts: this main strap includes a top strap and two side straps, where the top strap is located at the parietal bone at the ba...

[0076] strap connector

[0077] The strap connector is a part with a certain geometric shape and thickness, which is divided into the main strap connector and the neck connector according to the connected parts and functions. Wherein, the part connecting the top strap and the side strap is the main strap connector 70, and the main strap connector is composed of a top strap end 71, an upper strap end 72 and a side strap end 73, (for the structure, refer to Figure 6a , but not limited to Figure 6a The structure shown); while the part that connects the end of the main strap or the main strap and the lower strap is called the neck connector (such as Figure 6b shown in ). The strap connector is connected with other parts of the head strap to form a connection joint, which can strengthen the support strength, adapt to adjust the wearing angle, and be combined with other parts of the head strap to form a better fit with the shape of the human head head strap.

Abstract

The invention provides a breathing mask three-dimensional head tying band, a main tying band composing the breathing mask three-dimensional head tying band and processing methods of the main tying band and the breathing mask three-dimensional head tying band, and relates to a head tying band for a medical treatment breathing machine mask, a major component composing the head tying band and machine methods of the head tying band and the major component, in particular to the three-dimensional head tying band, the main tying band composing the three-dimensional head tying band and the processing methods of the three-dimensional head tying band and the main tying band. Most components of both the three-dimensional head tying band and the main tying band are formed by connecting straight-strip parts; the straight-strip parts are high in universality and easy and flexible to assemble, the assembly angle can be adjusted at will so that the main tying band and the three-dimensional head tying band comprising the main tying band can be better attached to the head, stress is more even, and the main tying band and the three-dimensional head tying band are more comfortable to wear. The processing methods of the main tying band and the three-dimensional head tying band are simple, gapless discharge can be realized, the cost can be reduced, the components are assembled flexibly and diversely, and therefore different requirements of a user can be met.

Description

technical field [0001] The present invention relates to a three-dimensional head strap used for a breathing mask of a medical ventilator, a main strap constituting it and a processing method thereof, especially a main strap composed of straight parts and a three-dimensional head strap including the same, There is also a processing method for the three-dimensional head strap. Background technique [0002] The head strap is used to fix the breathing mask at the appropriate position on the user's face. Therefore, the head strap should not only achieve a sufficient sealing effect when the mask is in contact with the face to prevent air leakage, but also maintain a certain fastening force to prevent use. The relative displacement of the mask occurs during sleep. In addition, the head strap should be safe and comfortable, with a soft veneer, reliable functional design, and a certain degree of stretch opening and resilience. [0003] It is known that the headgear needs to have on...
