Abstract

A treatment bag for contaminated fabrics is used to carry contaminated fabrics with high humidity. The main bag body (1) of the treatment bag is made of water-insoluble thin film material. Each side of the main bag body is provided with a seal-connect structure (2, 4) for sewing up edges of two-layer separate thin films. The seal-connect structures are water-soluble. Two leakage-proof heat-seal lines (3,7) extend from the bottom of the main bag body upwardly between the two seal-connect structures in a heat-seal manner, and highness of the two leakage-proof heat-seal lines is less than that of the main bag body, thus enabling the middle and lower part of the main bag body to form a small bag body for carrying liquid without liquid leakage. The treatment bag has advantages of simple structure and low cost.

Description

Contaminated fabric treatment bag and application thereof

Technical field

The present invention relates to a soiled fabric treatment bag for use in hospitals or other places with radiation, pollution, and infectivity to treat high humidity contaminated fabrics produced in such locations. Background technique

Say

Hospitals or other places with radiation, pollution, and infections produce a variety of contaminated fabrics with high humidity, such as rags, sheets, and mop heads after cleaning the floor. The current treatment methods for such contaminated fabrics are:

Method 1: Put these high-humidity contaminated fabrics into a bag made of ordinary water-insoluble materials (such as: PE, PP, PET ······), and then apply these before cleaning and disinfecting. The moisture-contaminated fabric is taken out of the bag and placed in the cleaning and disinfecting equipment. During the handling operation, the contaminated fabric is easily exposed to the environment and contaminates the environment, infecting the operator.

Method 2: These high-humidity contaminated fabrics are packed into a bag made of a high-temperature book water-soluble PVA material. The wall thickness of the bag is generally thicker, mostly above 40 microns. After the processing bag is loaded with contaminated fabric, it is not opened. In the case of airtightness, the washing and disinfecting equipment is put into the washing and disinfecting, and the processing bag can be dissolved and exposed to the high-temperature washing water to expose the contaminated fabric to water. However, after the water-soluble bag is loaded with the high-humidity fabric, the moisture can easily cause leakage of the heat-sealed seal or the bag body of the water-soluble bag, thereby causing cross-infection or secondary pollution; in addition, the water-soluble PVA material is more The thickness is also high. Summary of the invention

The invention is to overcome the deficiencies of the prior art and to provide a pollution fabric treatment bag, which can effectively treat high humidity pollution fabrics in hospitals and the like, and avoid cross infection and secondary pollution.

The technical solution of the present invention to solve the technical problem is: a pollution fabric treatment bag, the main bag body is a commonly used water-insoluble film material (such as: PE, PP, PET, etc.) bag body, in the main bag body Each side of the side is provided with a sealing structure for sewing the side separation film, the sealing structure is soluble and disintegrated in water; between the two sealing structures, the bottom of the main bag body is extended in a heat-sealing manner to seal the two heights less than the main The leakage preventing heat sealing line of the bag body height, the two leakage preventing heat sealing lines may be perpendicular to the bottom edge of the main bag body or heat sealed into a wide and narrow trumpet shape, so that the middle and lower parts of the bag body can be accommodated without A small bag of liquid leaking. Such a clever use of the low-cost ordinary water-insoluble material film bag body combined with the leak-proof heat sealing line can effectively prevent the liquid of the high-humidity fabric from leaking out; and when the sealing structure encounters the washing water, It can be destroyed to make the main bag body rupture and open into a sheet shape, which avoids the non-water-soluble bag body wrapping the fabric and causing incomplete washing and disinfection. In addition, the height of the leakproof heat seal line of the main bag body is set according to the amount of water that the high humidity fabric is expected to ooze out and the size of the single piece of the contaminated fabric. It is expected that the smaller the amount of water oozing or the smaller the volume of the single piece of contaminated fabric, The lower the height of the leakproof line is; the height of the two leakproof heat seal lines is less than 1/2 of the height of the main bag body.

The contaminated fabric treatment bag of the above solution may have a sealing structure in which the water-soluble PVA line is sutured in parallel. The two layers on both sides of the bag separate the film edges, so that when the washing water is encountered, the PVA line dissolves, and the two layers of the film on both sides of the main bag are separated. The sealing structure may also be a water-soluble PVA tape and a binder respectively bonding the separation films on both sides of the main bag body, so that when the washing water is encountered, the water-soluble PVA tape is dissolved, and both sides of the main bag body are dissolved. The two layers of film are separated. This facilitates the contamination of the fabric to the wash water for thorough cleaning and disinfection.

According to a further improvement of the present invention, the inner bag of the processing bag is further provided with an inner bag of a high-temperature water-soluble PVA material bag, and the two are integrally bonded in an adhesive manner. The high-temperature water-soluble PVA material refers to a water-soluble PVA material which is easily dissolved under water at 40 ° C to 90 ° C. A further solution is that the height of the main bag body is lower than the height of the inner bag body, which is 2/5^3/5 of the height of the inner bag body; or the height of the main bag body is equal to the inner bag bag. Body height. In this way, the main bag body can be used to replenish the liquid which may be leaked from the inner bag, and the bottom of the inner bag of the water-soluble PVA material is protected and strengthened after being loaded with high humidity and contaminated fabric, and the strength is deteriorated and easily damaged. The thickness of the layer bag can be greatly reduced compared with the thickness of the conventional single-layer PVA bag, generally according to the actual use, and is generally about 25 microns thick; thus reducing the amount of PVA material with higher cost and reducing the overall product. Cost; The height of the main bag body can be adjusted according to the quantity of the inner bag load. The more the inner bag load, the higher the height of the main bag body, so as to protect and strengthen the inner bag. .

In addition, the present invention also discloses the application of the above-mentioned contaminated fabric treatment bag, which is applied to a pollution fabric loaded with high humidity, and after the treatment bag is loaded with the pollution fabric, the cleaning and disinfection equipment is put into the washing and disinfecting in the case of being sealed without opening the package. After the treatment bag is exposed to high temperature water (generally 40 °C-90 °C), the bag body can be dissolved and ruptured to expose the contaminated fabric to water, but it can effectively prevent moisture infiltration of high humidity pollution fabric before putting into washing and disinfecting equipment. Leak out of the bag to prevent secondary pollution of the contaminated fabric after loading. More specifically, the treatment bag is applied to the treatment of high humidity contaminated fabrics produced in hospitals or other places with radiation, pollution, and infectivity, especially for high humidity mop heads that are loaded with clean ground.

In summary, the contaminated fabric treatment bag of the present invention compensates for the deficiency of the existing contaminated fabric treatment bag in a simple and novel bag structure in the case of cost reduction or no increase, that is, the treatment bag is loaded. After high-humidity pollution of fabrics in hospitals and other places, the washing and disinfecting equipment is put into washing and disinfecting without opening the package. After the treatment bag is exposed to high-temperature water, it can be dissolved and ruptured to expose the contaminated fabric to water, but it is put into washing and disinfecting equipment. It can prevent the moisture of the high humidity polluted fabric from leaking out of the bag outside the bag, effectively preventing the secondary pollution that may occur after the loaded fabric is loaded.
