Description

Technical Field

[0001] This utility model relates to the field of medical paper-plastic bag technology, and in particular to a highly permeable medical paper-plastic bag. Background Technology

[0002] In the medical field, medical paper-plastic bags are widely used for packaging various medical supplies, and their sealing structure has high requirements. Traditional sealing methods for medical paper-plastic bags commonly include drawstring, adhesive, and heat sealing. Drawstring sealing is relatively cumbersome, and the drawstring is prone to wear and loosening. Adhesive sealing reduces its stickiness over time and with environmental changes, affecting the seal. Heat sealing requires specialized equipment and is inconvenient to operate at any time. With the increasing demand for efficiency and convenience in medical work, there is an urgent need for a new sealing structure that can automatically tighten, reliably seal, and is easy to operate to meet the usage scenarios of medical paper-plastic bags.

[0003] Most existing medical paper-plastic bag sealing structures have varying degrees of defects. For example, drawstring bags are prone to opening if not tightened properly during handling, posing a risk of items falling out. Adhesive strips lose their stickiness after repeated use, resulting in poor sealing and allowing external dust and germs to enter, affecting the hygiene and safety of medical supplies. While heat-sealing provides a good seal, it relies on equipment and cannot be flexibly used for temporary access or rapid packaging, limiting the convenience and reliability of medical paper-plastic bags in practical use.

[0004] Therefore, a new type of highly permeable medical paper-plastic bag is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly permeable medical paper-plastic bag to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a highly permeable medical paper-plastic bag, comprising a paper layer, an inner layer installed on the inner wall of the paper layer, a thermoplastic layer installed on the top of the inner wall of the inner layer, two sets of symmetrical connecting holes opened on the thermoplastic layer, a handle installed in the connecting holes, an adhesive layer installed on the inner wall of the thermoplastic layer, and a release film installed on the end of the adhesive layer away from the thermoplastic layer.

[0008] Preferably, the thermoplastic layer has a wrinkled texture and is distributed radially.

[0009] Preferably, the handle has anti-slip holes, and the diameter of the anti-slip holes on the handle is larger than the diameter of other parts of the handle.

[0010] Preferably, a fixing strap is installed on the sidewall of the inner layer, and the fixing strap is elastic.

[0011] Preferably, the paper layer has ventilation holes that penetrate the inner layer, and an installation component is installed inside the ventilation hole, with a filter screen installed inside the installation component.

[0012] Preferably, the mounting component has an absorbent layer installed inside, and the absorbent layer is located at one end of the filter screen near the inner layer.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This highly permeable medical paper-plastic bag features a resilient, pleated sealing structure that offers significant advantages. The elastic pleats automatically tighten the bag opening using gravity, simplifying operation and improving the efficiency of medical staff in retrieving items. Furthermore, as the pleats shrink, the adhesive layers adhere to each other, further enhancing the seal and effectively blocking external dust and germs, ensuring a sterile environment for medical supplies.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a highly permeable medical paper-plastic bag.

[0029] Please see Figure 1-6 As shown, this embodiment is a highly permeable medical paper-plastic bag, including a paper layer 110, an inner layer 111 installed on the inner wall of the paper layer 110, a thermoplastic layer 210 installed on the top of the inner wall of the inner layer 111, two sets of symmetrical connecting holes 211 opened on the thermoplastic layer 210, a handle 230 installed in the connecting holes 211, an adhesive layer 220 installed on the inner wall of the thermoplastic layer 210, and a release film 221 installed at the end of the adhesive layer 220 away from the thermoplastic layer 210.

[0030] The thermoplastic layer 210 has a wrinkled texture and is distributed radially. The material of the wrinkled texture is a thermoplastic elastomer material with high elasticity and high toughness that meets medical standards. It has good tensile properties and shape recovery ability and can withstand repeated deformation operations.

[0031] The handle 230 has anti-slip holes 231. The diameter of the anti-slip holes 231 on the handle 230 is larger than the diameter of other parts of the handle 230. This design increases the friction when holding the hand, making it easier for the user to carry the paper-plastic bag stably.

[0032] A fixing strap 130 is installed on the side wall of the inner layer 111, and the fixing strap 130 is elastic. This design can fix the instrument and avoid the problem of the paper layer 110 and the inner layer 111 being punctured due to the movement of the instrument, thereby improving the overall antibacterial properties.

[0033] A ventilation hole 112 is provided on the paper layer 110, and the ventilation hole 112 penetrates the inner layer 111. An installation component 120 is installed in the ventilation hole 112, a filter screen 121 is installed in the installation component 120, and a water-absorbing layer 122 is installed in the installation component 120. The water-absorbing layer 122 is located at the end of the filter screen 121 close to the inner layer 111. This design can effectively replace and circulate the air in the bag, and the designed filter screen 121 can filter out dust in the air. The designed water-absorbing layer 122 is made of absorbent cotton, which can absorb moisture in the air when the air circulates.

[0034] Working principle: When using the paper-plastic bag, after placing the item inside, the bag hangs down under gravity. Due to the presence of the elastic corrugated thermoplastic layer 210, the thermoplastic layer 210 gradually stretches and converges towards the center of the bag opening under tension. As the thermoplastic layer 210 contracts, its own elastic potential energy is converted into a tightening force on the bag opening, causing the bag opening to converge inward, thus achieving automatic tightening of the bag opening. Moreover, this tightening method relying on the thermoplastic layer 210 can flexibly adjust the degree of tightening according to the weight of the item. Whether it is a lighter medical dressing or a heavier small medical device, the adaptive deformation of the corrugated texture can achieve a suitable tightening state, effectively preventing the item from falling out of the bag opening. Furthermore, the designed adhesive layer 220 allows the release film 221 to be torn off before lifting, ensuring the airtightness of the paper-plastic bag when the bag opening contracts.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
