Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical equipment technology, specifically to a disinfection cotton pad assembly. Background Technology
[0002] Disinfection of clinical instruments is a crucial infection control step in medical procedures. Currently, the disinfection of absorbent cotton pad substrates for the heads of small instruments such as forceps and scissors mainly relies on individually packaged, ready-to-use absorbent cotton pad substrates.
[0003] Existing technologies typically employ two methods: One involves directly tearing open the single-layer packaging and inserting the instrument head into the space between the cotton pad and the packaging bag for single-sided wiping. This method reduces the effective contact area of the alcohol because the instrument only contacts the alcohol-soaked non-woven fabric on one side, while the other side rubs against the barrier packaging material. The second method involves tearing the pre-folded cotton pad along the crease to create a double-sided disinfection chamber. However, in practice, limitations in the tear strength of the packaging material and defects in the crease-pressing process can easily lead to deviations in the tear path or incomplete packaging layering, requiring repeated adjustments by medical personnel. This is especially prone to operational errors in emergency situations.
[0004] In summary, there is an urgent need for a disinfection pad assembly that is easy to tear open and provides more reliable disinfection when disinfecting the heads of small medical devices. Utility Model Content

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0023] Example 1:
[0024] A disinfectant cotton pad assembly includes a packaging body 1. The packaging body 1 includes a first barrier film layer 11 and a second barrier film layer 12 laminated together. An absorbent cotton pad substrate 2 is disposed inside the packaging body 1. The absorbent cotton pad substrate 2 is fixedly connected to the inner surface of the first barrier film layer 11. One end of the packaging body 1 has a Y-shaped opening. The Y-shaped opening extends from the distal end to the proximal end of the packaging body 1 to form a forked channel. The packaging body 1 can be opened by separating the Y-shaped opening. The packaging body 1 is formed by a hot-pressing composite process of the first barrier film layer 11 and the second barrier film layer 12. The first barrier film layer is a polyester / aluminum foil / polyethylene composite film (thickness 80-120 μm), and the second barrier film layer 12 is a polyethylene / ethylene-vinyl alcohol copolymer (EVOH) composite film (thickness 60-100 μm). The composite of the two forms a highly barrier-resistant sealed cavity, thereby significantly reducing the evaporation rate of the disinfectant liquid absorbed by the absorbent cotton pad substrate 2. The absorbent cotton pad substrate 2 and the inner surface of the first barrier film layer 11 are formed by a peelable fixed connection through a hot melt adhesive layer. The absorbent cotton pad substrate 2 is made of non-woven fabric or cellulose substrate and can be bonded to the inner surface of the first barrier film layer 11 by hot melt adhesive. The absorbent cotton pad substrate 2 and the first barrier film layer 11 are both fixedly connected, that is, each side of the first barrier film layer 11 is connected to the absorbent cotton pad substrate 2.
[0025] Specifically, the Y-shaped opening is formed at the longitudinal end of the packaging body 1, creating a pre-designed weakened Y-shaped tear-inducing line with the packaging body 1. That is, the intersection of the Y-shaped opening and the packaging body 1 forms the tear-inducing line. During use, the tear path is guided by the Y-shaped opening. The Y-shaped opening extends from the distal end to the proximal end of the packaging body 1, forming a bifurcated channel at an angle of 30°-60°, preferably 45°. This creates a V-shaped opening after the packaging opens, increasing the contact area with the instrument head while preventing the instrument tip from piercing the sidewall.
[0026] Example 2:
[0027] Specifically, the packaging body 1 has a folded double-sided structure with a crease line in the middle. The apex of the Y-shaped opening is collinear with the crease line. In use, the folded packaging body 1 is opened through the Y-shaped opening to reveal a double chamber.
[0028] Specifically, the absorbent cotton pad substrate 2 is fixedly connected to the inner surface of the first barrier film layer 11 on both sides of the folded double-sided structure. The absorbent cotton pad substrate 2 is fixedly connected to both sides of the inner surface of the first barrier film layer 11. The absorbent cotton pad substrate 2 is uniformly fixedly connected to the inner surface of the first barrier film layer 11, and the absorbent cotton pad substrate 2 is used to impregnate with disinfectant, such as alcohol.
[0029] In use, the packaging is opened through the Y-shaped opening, and the head of the small medical device is inserted into the packaging. At this time, each side of the packaging is equipped with an absorbent cotton pad substrate, which can evenly disinfect the head of the medical device. Furthermore, in the folded double-sided structure, there is a crease line in the middle of the folded double-sided structure, and the apex of the Y-shaped opening is aligned with the crease line. The absorbent cotton pad substrate is fixedly connected to the inside of the packaging. In use, the Y-shaped openings are torn open to open the two sides of the folded packaging. Then, the head of the small medical device is placed on each side for disinfection. At this time, the contact area between the head of the small medical device and the cotton pad is increased, and the disinfection is more thorough.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
