The hygroscopic effect of spunlace nonwovens in surgical instrument sterilization packaging
- 2024-08-30
Through the actual application observation method, the actual application effect of spunlace nonwovens in surgical instrument packaging interlayers was observed. Spunlace nonwovens are used as spacers between surgical instrument packages. After pressure steam sterilization, they have good hygroscopicity, basically no wet packing phenomenon, storage resistance, and good practicality. Therefore, spunlace nonwovens are more suitable for pressure steam sterilization packaging hygroscopic materials.
Spunlace nonwovens are a kind of non-woven fabric that sprays high-pressure fine water flow onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. This type of nonwoven fabric is characterized by soft feel, fluffy, high hygroscopicity, good air permeability, no fiber scraps, etc. It is widely used in packaging materials for medical devices and supplies, as well as tray liners, medical wipers.
Spunlace nonwovens replace cloth pads as hygroscopic cloth pads between surgical instruments and instrument baskets, achieving good results.
1 Usage:
According to the size of the instrument basket, cut the spunlace non-woven fabric into different length and width specifications of cloth pads. After the surgical instruments and instrument baskets are cleaned and disinfected, when packing, first select the appropriate spunlace non-woven fabric according to the size of the instrument basket, pad the bottom of the instrument basket, and then put the surgical instruments in to separate the surgical instruments from the instrument basket before packing.
2 Observation results:
The spunlace non-woven fabric is used as a moisture-absorbing pad between surgical instrument packages. After pressure steam sterilization, it has good moisture absorption, basically no wet pack phenomenon, and is durable in storage and has good practicality. The results suggest that spunlace non-woven fabric is more suitable for pressure steam sterilization packaging hygroscopic materials.
3 Discussion
Wet pack is a phenomenon of package moisture caused by various reasons during pressure steam sterilization. The formation of wet packs in surgical instrument packages is due to the fact that during pressure steam sterilization, steam transfers heat energy to the surgical instrument package. The heat conduction of the metal in the surgical instrument package is fast, so a lot of condensed water is generated. The metal in the instrument package does not absorb the condensed water. The condensed water is directly precipitated from the surface of the metal object. If there is no time to drain it, it will infiltrate the outer packaging and form a wet pack. After the wet pack is generated, a continuous liquid channel is formed inside and outside the package, thereby destroying the effective barrier function of the packaging material to block microorganisms, causing the sterilized surgical instrument package to be invaded by microorganisms, causing contamination inside the package, resulting in sterilization failure. The placed utensils should be separated by absorbent cloth, gauze or medical absorbent paper. Surgical instruments and instrument baskets are both metal objects, so when the instrument basket is used to hold surgical instruments, the absorbent cloth should be placed at the bottom to facilitate the absorption of moisture and the evaporation of water, and prevent the formation of wet packs after pressure steam sterilization.
Cotton cloth is processed into cloth pads of different specifications that are suitable for the instrument basket. They are placed at the bottom of the surgical instrument basket as moisture-absorbing cloth. No wet bags are produced after pressure steam sterilization. However, since the cloth pads need to be counted and cleaned, the cost and work links increase, affecting work efficiency. Therefore, spunlace non-woven fabrics are used instead of cloth pads as moisture-absorbing cloths between surgical instruments and instrument baskets. The effect after pressure steam sterilization is the same as that of cloth pads, and no wet bags are produced. Spunlace non-woven fabrics are low-priced, disposable, reduce work links, and improve work efficiency. They are worth promoting and applying.
