Abstract
A high-barrier-performance moist-load-resistant anti-infection disposal bag and an application thereof. The structure of the disposal bag comprises: a mouth tying band 1; and a thin film bag body 2, wherein the thin film bag body is bonded with a bonding structure to form a closed body. The thin film bag body can be at least one piece of quadrilateral non-water-soluble material. The bonding structure is capable of separating and debonding in water and may comprise two ends of the thin film bag which are overlapped and bonded together with a narrow band 3 by means of a strip shaped thin adhesive layer ‘a’. The disposal bag is intended to provide anti-infection, sealing and preservation performance and reduced of the risk of heat transfer and virus spreading from medical supplies.
Description
HIGH-BARRIER-PERFORMANCE MOIST-LOAD-RESISTANT
ANTI-INFECTION DISPOSAL BAG AND APPLICATION THEREOF
Technical Field
The present invention relates to the field of A61, in particular to a hi gh -barri er-performance moist-load-resistant anti -infection disposal bag and an application thereof
Background of the invention
Hospitals bear the burden of treating diseases and saving lives in society; however, due to the converge of numerous patients, they have become a source of hidden danger of virus transmission. For example, a variety of infectious diseases such as infectious pneumonia, tuberculosis, cholera, and AIDS have the potential to transmit in hospitals. In addition, during the process of doctors and nurses treating patients, it is also possible to produce a large number of soiled medical articles, such as medical textiles, containers and utensils with body fluids, blood, excreta and germs. Improper disposal of the above-mentioned medical articles and wastes very easily leads to cross-infection between patients or between patients and medical treatment staffs. The best way to treat such soiled medical textiles is to disinfect the place where they are produced, enclose and isolate these soiled medical textiles in situ, and then transported away for further disinfection and washing treatments. Moreover, the spread of viruses also easily occurs during the sealed preservation and disinfection of medical articles.
When medical care staffs collect soiled medical textiles, they usually use some cloth packaging bags or ordinary plastic packaging bags for packing. However, using such cloth packaging bags or ordinary plastic packaging bags to pack soiled medical textiles may pose great hidden danger of contamination: (1) cloth packaging bags have no tightness, so germs or viruses can still diffuse and spread through the air during the process of collecting, transporting, washing and disinfecting soiled medical textiles; and (2) when ordinary plastic packaging bags are used to pack soiled medical textiles, the medical care staffs need to open the plastic packaging bags and take out the soiled medical textiles when washing and disinfecting the soiled medical textiles, and this process will increase the chance of infection to the medical care staffs and contamination to the workplace.
The prior invention (CN 202220562749.5) provides a medical bag for soiled clothing, the main structure of which comprises a mesh base frame provided with an upward opening and a disposal bag in the base frame. The structure can realize rapid collection of clothing, and during cleaning, the disposal bag can be directly taken out of the frame for transportation and cleaning. However, this structure only focuses on accelerating the collection of soiled textiles and does not practically ensure the isolation of contaminants from the external environment, so it cannot solve the technical problem of reducing the risk of secondary contamination and infection. The prior invention (CN 202010539117.2) provides a multifunctional bedding and clothing disposal bag comprising a rectangular body with four corners cut off, wherein various sealing structures are arranged in the middle of the long sides of the rectangle. The multifunctional bedding and clothing disposal bag can not only be directly spread on the floor to collect and sort clothes, but can also wrap and seal the clothes by means of drawstring sleeves arranged at the bevel edges. Although it is convenient and practical to use, a direct contact between internal contaminants and external air may occur during actual use due to the fluctuation of wrapping and sealing of the drawstring sleeves, resulting in a relatively poor contaminant diffusion prevention. The prior invention (CN 202121252228.1) provides a medical waste disposal bag with a sealing structure. By rotating a button, a screw can be rotated to drive a sliding plate and a clamping block to move, causing a relevant rope to be tensioned and positioned, thus avoiding contaminant leakage. However, during actual use, limited by the poor sealing performance of the rope, the product thereof can often only provide reliable stability, while the sealing performance cannot reach complete isolation from the external environment before cleaning, so it cannot completely prevent the contaminants from diffusion.
The prior invention (CN 213978286 U, the patent granted to the present applicant) provides a novel disposal bag for textile collection and washing. A body of the disposal bag is made of one or more tubular or sheet-like non-water-soluble thin films bonded by an adhesive, and the bottom of the body is sealed at a heat-sealing line by means of hot melt sealing to form a bottom. Structures such as a strap are further comprised, thus realizing complete sealing from textile collection through cleaning, with a good protection and isolation effect. However, the practicability thereof during practical application, especially the service effect in a cleaning process, needs to be improved.
Therefore, in order to solve the above problems, the present application provides an anti-infection textile disposal bag, which can alleviate the diffusion of contaminants in the bag and realize convenient sealing and preservation.
Summary
In order to solve the above problems, a first aspect of the present invention provides a high-barrier-performance moist-load-resistant anti-infection disposal bag, wherein the structure of the disposal bag comprises: (1) a mouth tying band, and (2) a thin film bag body, wherein the thin film bag body is bonded with a bonding structure to form a closed body.
Traditional disposal bags have the technical problems of poor strength and easy breakage when loaded with high-humidity textiles, especially during the process of moving and using.

In addition, the medical and health care field has higher mechanical strength and tightness requirements on disposal bags, and conventional disposal bags cannot meet the increasingly high use requirements for anti-infection performance. By means of a simple and feasible structure, the anti-infection textile disposal bag provided by the present application can comprehensively achieve multiple properties such as mechanical strength, tightness, and moisture resistance, can provide effective safety guarantee when used for washing, sealing and disinfection of medical textiles, has a strong barrier property, can effectively reduce the contamination risk in a workplace, and has prominent practical application value in the context of coronavirus epidemic.

After extensive experiments and explorations, the applicant has found that a thin-film-type narrow band made of only a water-soluble/water-di sintegrable material is substantially affected by the environmental humidity, causing poor weather resistance and use limitations; whereas, water-soluble textiles, non-water-soluble textiles, or non-water-soluble thin films with micropores/fine pores can exactly make up for the issues of substantial environmental humidity influence and insufficient weather resistance; in addition, in order to further improve the product performance, the non-water-soluble textile material used as the material of the narrow band has better weather resistance.
Preferably, the non-water-soluble textile material is non-water-soluble fibrous textile or mesh textile.
In a preferred solution, the narrow band is a common non-water-soluble textile coated with a water-soluble material In a preferred solution, the water-soluble material in the common non-water-soluble textile coated with the water-soluble material is water-soluble PVA.
In the present application, the water-soluble opening mode of the anti-infection textile disposal bag is novel During cleaning, the textiles tumble inside the bag, generating an expansive force on the bonding structure. The water-soluble mouth tying band and narrow band are exposed to the water environment, which makes them lose their mechanical properties and gradually open after coming into contact with water, finally causing the body of the bag to break apart to release the textiles, thus achieving the service effect. The bag can be effective when used to hold a moist load.
In a preferred solution, the raw material of the water-soluble PVA comprises the following components in parts by mass: 80-100 parts of a polymer raw material, 1-10 parts of a solid filler, 15-30 parts of an auxiliary agent, and 5-25 parts of deionized water.
In a preferred solution, the polymer raw material is a mixture of PVA and a water-soluble polymer at a mass ratio of 6-8:0.8-1.
In a preferred solution, the water-soluble polymer is polyvinylpyrrolidone In a preferred solution, the weight average molecular weight of PVA is 50000-80000 In a preferred solution, the solid filler is at least one of talcum powder, carbon black, white carbon black, zinc oxide, and bentonite.
In a preferred solution, the auxiliary agent is a surfactant and a plasticizer at a mass ratio of 0.1-1:10-30.
In a preferred solution, the surfactant is polyoxyethylene stearyl ether.
In a preferred solution, the plasticizer is sorbitol and glycerol at a mass ratio of 1:1.

Preferably, the mouth tying band is in the shape of an elongated strip and has a width of 10-200 mm and a thickness of 20-100 pm.
Further preferably, the length of the mouth tying band is consistent with the length of the thin film bag body, and the mouth tying band can be placed inside the bag or fixed on the thin film bag body by means of spot bonding.
Further preferably, the mouth tying band is parallel to a long side of the thin film bag body and is fixed in a position of an outer surface of the thin film bag body by means of spot bonding with a water-soluble or non-water-soluble viscid adhesive.
Preferably, the thin film bag body is a flat cuboid body with a built-in volume, and the thin film bag body has a long side length of 50-200 cm and a short side length of 40-190 cm.
Further preferably, the thin film bag body has a thickness of 15-100 Rm.
Preferably, the narrow band is fixed in parallel to one side of the thin film bag body and connected to the thin film bag body.
Further preferably, the narrow band has a width of 5-100 mm Further preferably, the length of the narrow band is consistent with that of the thin film bag body.
Further preferably, the number of the narrow bands is 2.
Preferably, the bonding structure on the thin film bag body is a connecting structure A at which one end of the thin film bag body overlaps the other end with an overlapping width of 1-300 mm. The overlapping part is bonded together with the narrow band by means of an adhesive to form a closed body.
In a preferred solution, the bottom of the thin film bag body is hot-sealed in a hot-melt hot-seal welding manner to form the bag.
In the present application, by means of the arrangement of the connecting structure A, a tight void-free disposal bag is formed, and after the formed bag is used to collect items, the narrow band can be fully prevented from coming into direct contact with the moist load in the bag, thereby ensuring that the strength of the body of the bag is protected from damage. When the disposal bag is placed in a washing machine, water continues to erode the narrow band, whereupon the two non-water-soluble layers of the body of the bag separate apart and the clothes are released from the fissure.
In a preferred solution, the number of the connecting structures A is two, and the connecting structures A are located on the same outer surface of the thin film bag body or respectively on the two different outer surfaces of the thin film bag body.
In a preferred solution, the adhesive at the connecting structure A is a 2-100 mm wide strip-shaped thin adhesive layer a.
In a preferred solution, one side of the strip-shaped thin adhesive layer a covers the overlapping part at the junction, leaving a bonding coverage with a width of at least 1 mm on thin film surfaces at the two ends of the thin film bag body; the other side of the strip-shaped thin adhesive layer a is fully covered and bonded with the narrow band.
In a preferred solution, the length of the strip-shaped thin adhesive layer a is consistent with the length of the thin film bag body, and the width of the strip-shaped thin adhesive layer a does not exceed the range of the width of the narrow band.
In a preferred solution, the water-soluble or non-water-soluble adhesive bonds the thin film bag body and the narrow band to form the connecting structure A, and the non-water-soluble thin films at two ends of the overlapping structure in the connecting structure A have a tensile force greater than 0.3 N per 10 square millimetres of glued area.
By means of extensive experiments and explorations and after various adjustments made to the structure of the disposal bag, the applicant has found that when the connecting structure A is used as the bonding structure, on the one side, by controlling the width of overlapping between one end and the other end of the thin film bag body, the capacity of the disposal bag to hold textiles with high humidity can be effectively improved. The greater the overlapping width, the more difficult it is for water in the textiles in the bag to seep to the position of the narrow band, and the stronger the water/moisture-resistant loading capacity of the body of the bag. On the other side, by changing the bonding mode to cover the overlapping part of the non-water-soluble thin film with the adhesive in the adhesive layer at the junction and fully cover and bond the two ends of the non-water-soluble thin film with a narrow band, a body structure free from air leakage points in the overlapping part of the non-water-soluble thin film can be realized. However, for a conventional disposal bag, non-water-soluble thin films at two ends of a thin film bag body are respectively glued with a viscid adhesive and bonded without sealing the overlapping part of the non-water-soluble thin film at the junction where air leakage may occur; on the other side, the water-soluble material and the non-water-soluble material cannot be welded in a hot-melt hot-seal manner, so there are air leakage points at the overlapping part of the non-water-soluble thin film and air leakage at the hot-melt hot-seal weld site between the water-soluble material and the non-water-soluble material, leading to the technical problem that the tightness of the whole body of the bag cannot be guaranteed. The innovative bonding method used in the present application can substantially prevent the anti-infection textile disposal bag from air leakage, and the anti-infection textile disposal bag can maintain the sealing effect for a long time. After further exploration, it has been found that providing an adhesive as a 2-100 mm wide strip-shaped thin adhesive layer a at the connecting structure A can effectively balance the bonding strength of the body of the bag and the production cost. The obtained disposal bag can maintain excellent bonding strength when holding both dry and moist textiles and can function to maintain closed packaging and isolation even after being beaten and violently shaken, which is convenient for washing and loading soiled medical textiles Preferably, the material of the strip-shaped thin adhesive layer a may be a water-soluble or non-water-soluble adhesive. Further preferably, the material of the strip-shaped thin adhesive layer a is a water-soluble viscid adhesive.
Preferably, the water-soluble viscid adhesive is a water-soluble liquid glue and/or a water-soluble hot melt adhesive.
When washing medical textiles in the anti-infection textile disposal bag, on the one side, it is necessary to ensure that the bonding strength can be maintained while the anti-infection textile disposal bag is holding moist textiles and that the disposal bag remains sealed; on the other side, after being immersed in water, the disposal bag needs to be quickly disintegrated to release the content for washing. However, traditional disposal bags cannot meet both of the above two conditions. In the present application, on the basis of the structure of a specific disposal bag, the material of the strip-shaped thin adhesive layer a is controlled to be a water-soluble viscid adhesive and/or a non-water-soluble viscid adhesive, which can not only ensure the bonding strength of the disposal bag while holding textiles, especially in terms of improving the moist load resistance of the disposal bag, but can also shorten the time for the disposal bag to break and disintegrate in water, that is, the disposal bag can quickly disintegrate within 5 min after being immersed in the liquid. The use of the water-soluble viscid adhesive can realize a faster breaking and disintegration speed of the body of the bag in water, and the use of the non-water-soluble viscid adhesive can realize a higher moist load resistance of the body of the bag.
Further preferably, the adhesive force of the material of the strip-shaped thin adhesive layer a to the non-water-soluble material is greater than that to the water-soluble material.
In the course of exploration, the applicant has found that the material of the strip-shaped thin adhesive layer a has a crucial influence on the effect of the disposal bag during washing. When the bonding effect of the material is relatively poor, the disposal bag easily breaks and disintegrates when it is filled, leading to a seal failure; in addition, contaminants on medical supplies easily spread with a high risk factor. However, when the adhesive force of the material of the strip-shaped thin adhesive layer a to the non-water-soluble material is less than that to the water-soluble material, the viscid adhesive easily falls off and sticks to the textiles during washing. In addition, when the adhesive force of the viscid adhesive to the non-water-soluble material is greater than that to the water-soluble material, the obtained anti-infection textile disposal bag can maintain the sealing effect under non-washing condition, and during washing, the anti-infection textile disposal bag can quickly disintegrate while allowing the viscid adhesive to stick to the non-water-soluble material without falling off to the textiles. It shows an optimal effect at different stages of action and has positive significance for both the suppression of epidemic situation and the blockage of viruses In a preferred solution, the water-soluble viscid adhesive is any one of a water-soluble acrylic adhesive, a water-soluble polyvinyl alcohol glue, and a water-soluble hot-melt acrylic adhesive A second aspect of the present invention provides an application of the above high-barrier-performance moist-load-resistant anti-infection disposal bag, including an application of the disposal bag in sealed transportation, sealed washing, and sealed storage.
Beneficial Effects: 1. The high-barrier-performance moist-load-resistant anti-infection disposal bag provided by the present application has excellent moisture resistance and moist textile load resistance and can ensure that the body of the bag is fully sealed, the protective isolation effect is good, and the barrier property is reliable; in addition, the disposal bag is particularly suitable for collecting textiles soiled by highly contagious and airborne infectious sources, has excellent safety and reliability, and is suitable for use in various sites of medical and emergent health events.
2. The high-barrier-performance moist-load-resistant anti-infection disposal bag provided by the present application has a novel water-soluble opening mode. During cleaning, the textiles tumble inside the bag, generating an expansive force on the bonding structure. The water-soluble mouth tying band and narrow band are exposed to the water environment, which makes the water-soluble mouth tying band and narrow band lose their mechanical properties and gradually open after coming into contact with water, finally causing the body of the bag to break apart to release the textiles, thus achieving the service effect.
3 The special narrow band prepared in the present application can effectively form a water-soluble bonding structure, but it also has a general water contact resistance, so that it can effectively resist disintegration and collapse when disturbed by external humid air during storage, thereby maintaining a good sealing effect, and can also smoothly disintegrate under cleaning condition, thus fully releasing the internal content
