Patent Description:
At present, guide wires in endovascular surgery are very important and an important part of surgery. These guide wires have broad application prospects in angiography, coronary angiography, valve replacement, coronary artery replacement and so on. For all these steps, one or two or more guide wires are used now. They are very expensive and difficult to protect. Using them in the market's existing technology can solve different problems. First, it is the length issue of the guide wire and its toughness problem. According to the professional requirements, the length may be between <NUM> to <NUM>, and they are used in a PE pipe.

The existing urinary catheter is pulled out and inserted into a large tray or a special tray including physiological saline. The use of this guide wire basin is risky. Due to the length and its flexibility, if the operation is not careful, the guide wire will jump out of the guide wire basin, thereby leading to product contamination. These specific guide wire basins require <NUM> to <NUM> in height. The packaging for special purposes is a very large volume, which increases the cost of transportation, sterilization, storage and physiological saline used in the clinical process. If the guide wire needs to be replaced, it must always be placed in the guide wire basin, which is very inconvenient to use.

<CIT> discloses a guidewire insertion assembly.

In view of the shortcomings of the prior art, the present invention provides a drape including an integrated guide wire use device, which solves the following problem: the packaging for special purposes is a very large volume, which increases the cost of transportation, sterilization, storage and physiological saline used in the clinical process, and if the guide wire needs to be replaced, it must always be placed in the guide wire basin, which is very inconvenient to use.

In order to achieve the above objective, the present invention is implemented as in claim <NUM>.

Preferably, the drape body comprises a surface layer, a water-absorbing layer, an antibacterial layer and a bottom lining layer, a bottom of the surface layer is stitched and connected to a top of the water-absorbing layer.

Preferably, a bottom of the water-absorbing layer is stitched and connected to a top of the antibacterial layer, and a bottom of the antibacterial layer is stitched and connected to a top of the bottom lining layer.

Preferably, the water-absorbing layer is woven by blending polyacrylonitrile fiber and polyethylene oxide fiber, the antibacterial layer uses bamboo charcoal fiber as a raw material, and the bottom lining layer uses pure cotton as a raw material.

Preferably, the surface of the drape body is stitched and connected with a fixing line.

Preferably, the guide wire bag uses PE as a raw material.

Preferably, the surface layer comprises a first surface layer, a second surface layer and a third surface layer, the first surface layer is separately stitched and connected to surfaces of the second surface layer and the third surface layer, and the second surface layer is stitched and connected to the surface of the third surface layer.

Preferably, the first surface layer uses cobes21G PP+<NUM> airlaid as a raw material, the second surface layer uses Transparent PE <NUM> as a raw material, and the third surface layer uses cobes2730/pe27a+spu30B as a raw material.

The drape body is an existing one, which is an infection control non-woven fabric covered with an adhesive used in an operating room, and is generally made of a non-woven fabric or a PE composite non-woven fabric. The present invention improves the drape body by adding a water-absorbing layer, an antibacterial layer and a bottom lining layer, and setting the surface layer of the drape body as a three-layer layered structure comprising a first surface layer and a second surface layer and the third surface layer. In general, the first surface layer is a composite layer compounded by PP (polypropylene) and airlaid (dust-free paper) through an adhesive, a transparent polyethylene layer is used as the second surface layer, and the third surface layer is a composite layer compounded by PP (polypropylene) and polyethylene (PE) through an adhesive.

The above-mentioned PP, PE, and dust-free paper are all commercially available existing products.

In the present application, in particular, the first surface layer uses cobes21G PP+<NUM> airlaid as a raw material, that is, a composite layer compounded by PP (polypropylene) with a gram weight of <NUM> grams per square meter and airlaid (dust-free paper) with a gram weight of <NUM> grams per square meter through an adhesive produced by the applicant is used; the second surface layer uses Transparent PE <NUM> as a raw material, which refers to transparent PE with a thickness of <NUM> made by a blow molding method; and the third surface layer uses cobes2730/pe27a+spu30B as a raw material, which refers to a composite layer compounded by PE (polyethylene) with a gram weight of <NUM> grams per square meter and blue PP (polypropylene) with a gram weight of <NUM> grams per square meter through an adhesive produced by the applicant using a casting method (code: cobes2730).

In particular, the blow molding method is to extrude plastic into a thin tube, then blow the plastic to a required thickness by high-pressure air while it is hot, and then cool it to shape and rewind.

The casting method is to melt PE particles through a screw, flow out at a required width through a mold head, perform molding by a calender roll, and cool it to shape, so that a finished product of cast film is finished.

PP is a spunbonded nonwoven fabric. After a PP polymer is extruded and stretched to form continuous filaments, the continuous filaments are then laid into a web, and then it is subjected to a reinforcement treatment of thermal bonding or chemical bonding, so that the web turns into a non-woven fabric.

Airlaid is also called an Airlaid pulp nonwoven fabric, which is one of dry nonwoven fabrics. Wood pulp fiber is pulverized and stirred, air-laid into a web and then molded, bonded by a chemical adhesive, and then baked and consolidated into a fabric.

Preferably, an outer side of the protective bag is fixedly provided with a convex block, and a material of the convex block is polyethylene.

Preferably, a right end part of the guide wire bag is a horn-shaped connector that expands toward the end part, and the disinfection connection port and the drain plug are provided on the horn-shaped connector, and a protective film is encapsulated at a port of the disinfection connection port.

The protective film is made of a microporous, breathable and waterproof material, such as a breathable PE film, or a composite film of breathable PP and breathable PE. It can isolate large water molecules and permeate small gas molecules. When sterilizing, a sterilant gas can enter the guide wire bag through the protective film for sterilization, but it is difficult for other water molecules, bacteria and other macromolecules to enter, thereby playing the role of barrier and protection.
