Description

Technical Field

[0001] The utility model relates to the technical field of braided tubes, in particular to a new type of braided tube used for medical equipment. Background Art

[0002] As an important component in modern industry, the hose is widely used in the transportation of gas, liquid, etc. in various fields. At present, the commonly used hose structure generally includes an inner tube and an outer tube, and a braided layer is arranged between the inner tube and the outer tube. The braided layer is woven from fiber filaments or steel wires and other materials, which can significantly enhance the strength, compression resistance, wear resistance and other properties of the hose. In the medical field, the braided tube, as an important component of medical equipment, plays an indispensable role in medical equipment such as catheters and infusion tubes.

[0003] At present, most traditional braided tubes for medical equipment are braided in a single material or simple structure. This design has shown its limitations in certain applications. Traditional braided tubes may have problems such as insufficient pressure bearing capacity, poor flexibility, and easy creases, which will affect the normal operation of medical equipment and the treatment effect of patients. The braided tubes have relatively insufficient anti-bending performance. During the transportation of medical devices, medical hazards may be caused due to insufficient anti-bending and anti-wrinkling capabilities. The safety protection performance is relatively insufficient. For this reason, we propose a new type of braided tube for medical equipment to solve the above problems. Utility Model Content

[0030] Further, the anti-bending transverse band 4 is evenly arranged on the outside of the annular anti-bending ring 3 in a ring shape, and the annular anti-bending ring 3 is evenly arranged on the inside of the anti-bending transverse band 4;

[0031] By arranging the anti-bending transverse band 4 in a ring shape and evenly arranging it on the outside of the annular anti-folding ring 3, the annular anti-folding ring 3 and the anti-bending transverse band 4 can be folded and woven with each other to play the role of a keel, with good anti-bending and anti-puncture effects, avoiding creases when the pipe is bent, and having excellent tensile properties.

[0032] Furthermore, the inner positioning tube 5 and the outer positioning tube 6 are both shaping positioning tubes, the inner side of the annular anti-bending ring 3 is connected to the inner positioning tube 5, and the outer side of the anti-bending transverse belt 4 is connected to the outer positioning tube 6;

[0033] By setting the inner positioning tube 5 and the outer positioning tube 6 as shaping positioning tubes, the annular anti-folding ring 3 is hot-melted to the surface of the medical diversion inner tube 1 by the inner positioning tube 5, and the anti-bending transverse band 4 is hot-melted to the inner side of the heat-resistant outer tube 2 by the outer positioning tube 6. When the pipeline is bent, the annular anti-folding ring 3 and the anti-bending transverse band 4 are not prone to twisting and deviation, and have good load-bearing fixation.

[0034] Furthermore, the medical diversion inner tube 1 is a medical-grade diversion tube, the heat-resistant outer tube 2 is a heat-insulating tube, and both the medical diversion inner tube 1 and the heat-resistant outer tube 2 are made of a soft tube material and are bendable;

[0035] By setting the medical diversion inner tube 1 as a medical-grade diversion tube with high medical conditions, the heat-resistant outer tube 2 is a thermal insulation pipe, which plays a role of thermal insulation, prevents temperature loss in the tube, and prevents external burns. The medical diversion inner tube 1 and the heat-resistant outer tube 2 are both made of soft hose material and are bendable. The whole has good flexibility and resistance, can be bent, and is not easy to produce creases and wrinkles during bending, and has excellent durability.

In addition, the outer positioning tube 6 is tightly sleeved on the outer side of the medical diversion inner tube 1 by the annular anti-folding ring 3 and the anti-bending transverse band 4. The overall tube body is woven relatively densely and has a good load-bearing effect.

[0042] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device belongs to a simple series and parallel connection circuit. There is no innovation in the circuit connection.

[0043] Working principle: annular anti-folding rings 3 are arranged at equal distances on the outside of the medical diversion inner tube 1, and the outside of the medical diversion inner tube 1 is wrapped with a heat-resistant outer tube 2, which plays a role of heat insulation and heat preservation, prevents the temperature loss in the tube, and prevents external scalding. The inner wall of the heat-resistant outer tube 2 is evenly provided with anti-bending transverse belts 4 in a ring shape, so that when the heat-resistant outer tube 2 is wrapped on the outside of the medical diversion inner tube 1, the annular anti-folding ring 3 and the anti-bending transverse belt 4 can be folded and wrapped with each other, tightly woven and connected together, to achieve an anti-bending weaving effect. The annular anti-folding ring 3 can play a role of transverse anti-bending, and can play a role of limiting and positioning support for the anti-bending transverse belt 4;

[0044] The annular anti-folding ring 3 cooperates with the anti-bending transverse belt 4 to play an anti-bending protection role. The annular anti-folding ring 3 can support the anti-bending transverse belt 4. The anti-bending transverse belt 4 can have good toughness when the pipeline is bent, and is not easy to cause bending, creases, etc. The annular anti-folding ring 3 is hot-melted from the inner positioning tube 5 to the surface of the medical diversion inner tube 1, and the anti-bending transverse belt 4 is hot-melted from the outer positioning tube 6 to the inner side of the heat-resistant outer tube 2, so that when the pipeline is bent, the annular anti-folding ring 3 and the anti-bending transverse belt 4 are not easy to twist or deviate, and the load-bearing fixation is good. The anti-puncture braided tube 7 is spirally wrapped and sleeved on the outside of the heat-resistant outer tube 2, which has anti-puncture and anti-bending effects. The overall braided tube has high strength, which makes the device excellent in anti-bending and anti-crease capabilities. It is not easy to wrinkle and bend during medical operations, and the operation is relatively safe and stable, which solves the problems of relatively insufficient anti-bending performance of existing braided tubes, easy to cause medical risks, and relatively insufficient safety protection performance.
