Problems solved by technology

However, the use of cotton non-woven dressings in surgery is very limited because non-woven cotton dressing products are rather stiff and their cost is too high to attract the attention of hospitals

Embodiment 1

[0064] This embodiment 1 is a piece of 18 "(inches) * 18 "(inches) 2 layers of abdominal surgical towels made by 100% plant fiber spunlace non-woven fabric, adopting cross-laying, the grammage of cloth is 40 grams / per square meters. To clarify, 18" x 18" is the most common size for abdominal drapes. The abdominal surgical drape of this embodiment feels soft and easy to bend like a gauze abdominal surgical drape. The tensile strength of this embodiment in both directions is higher than the standard requirements for surgical dressing sheets. When the abdominal surgical drape of this embodiment is compared with the gauze abdominal surgical drape of the same size (product size) and equal weight (per dry weight) (as shown in Table 1), the water absorption of each abdominal surgical drape of this embodiment The volume and unit water absorption are about twice that of gauze abdominal surgical drapes. It should be noted that the actual size of the gauze abdominal surgical drapes be...

Embodiment 2

[0066] This embodiment 2 is a piece of 11.5 "(inches) x 11.5 "(inches) 2 layers of abdominal surgical towels made of 100% plant fiber spunlace non-woven fabric, using cross-lapping, the grammage of the cloth is 40 grams / per square meters. That is, relative to Embodiment 1, the size of this embodiment is much smaller, and the water absorption of each abdominal surgical towel in this embodiment is the same as that of a gauze abdomen with a size of 18 "(inches) * 18 "(inches). Each piece of surgical drapes absorbs approximately the same amount of water. The tensile strength of the abdominal surgical drape of this embodiment in both warp and weft directions is higher than the standard requirements for surgical dressing sheets. In Table 1, the product size and dry weight of each piece of abdominal surgical drape in this embodiment are about half of that of gauze abdominal surgical drape, and the water absorption of each piece is roughly the same, but the unit water absorption is a...

Embodiment 3

[0068] This embodiment 3 is a piece of 11.5 "(inches) x 11.5 "(inches) single-layer abdominal surgical towels made of 100% plant fiber spunlace non-woven fabric, which adopts cross-lapping, but the grammage of the cloth is 80 grams / Per square meter, relative to Example 2, the grammage of the cloth in this example is twice that of Example 2. The tensile strength of the abdominal surgical drape of this embodiment in both warp and weft directions is higher than the standard requirement of the dressing sheet. In Table 1, the size (product size) of the abdominal surgical drape of this example is the same as that of Example 2. However, the grammage of the cloth in this example is twice that of Example 2, and only one layer of spunlace nonwoven is required. Cloth is made to form a single-layer abdominal surgical towel, and its water absorption capacity and unit water absorption capacity are all approximately the same as in Example 2.

Abstract

The invention relates to surgical dressing with great water absorption property and an application of the same. The surgical dressing with great water absorption property is applied to hospital surgeries and comprises at least one layer of surgical towel sheet made of a spunlaced non-woven fabric. The spunlaced non-woven fabric has first fiber material. The first fiber material is selected from atleast one fiber of plant fibers, viscose fibers, bamboo fibers, modal fibers and tencel. The surgical dressing with great water absorption property has features required by various surgeries, such asgreat water absorption property, great tensile strength, adhesion resistance to an exposed wound, great capillary absorption action, villus prevention and yarn thread prevention. The surgical dressing with great water absorption property can be especially suitable for blood and effusion absorption in laparotomy or less-invasive operations with small wounds; expansion and small-wound operation safety is enhanced due to the great water absorption property; and a problem of accidental dressing residual in a patient body after the surgery can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of medical surgical dressings, in particular to a highly water-absorbent plant fiber spunlace non-woven surgical dressing and its application. Background technique [0002] During surgery, disposable absorbent dressings are used for blood absorption and wound debridement. There are two main types of absorbent dressings used in hospital procedures: [0003] (a) Laparotomy Drapes (also known as Abdominal Drapes), for laparotomy with open incisions where large amounts of blood and exudate will need to be absorbed with Abdominal Drapes. Abdominal drapes are generally made of cotton woven gauze with a short radiopaque barium sheet sewn to one side of the abdominal drapes. If abdominal drapes are accidentally left inside a patient, they can be traced by X-ray detection. The radiopaque barium sheet is a strip of PVC rubber containing approximately 60% barium sulfate by weight. Abdominal drapes must be relativel...
