Introduction to the performance of surgical gowns

Introduction of surgical gowns

Surgical gown fabric is a kind of medical protective fabric, which mainly focuses on the protective performance. The protective properties include the ability to prevent the penetration of fluids and microorganisms. During medical visits, medical staff will inevitably come into contact with patients' blood and body fluids, which are often prone to carry HBV (hepatitis B virus), HCV (hepatitis C virus) and HIV pathogens.

The safety of patients is easily endangered due to pathogens such as hairs and particles that are easily carried on the surface of ordinary surgical gowns. Sterile surgical gowns also make the operator cleaner and tidier and less likely to produce dander or dust. At the same time, a good gown should consider the tensile strength and abrasion resistance of the fabric, because torn and broken clothing can lead to direct contact of bacteria with the medical staff's skin, and the gown is useless. In addition, patient blood will be spilled during surgery, so surgical gowns must also have a certain level of absorbency and resistance to water pressure. In addition, surgical gowns should also meet the requirements of comfort, flame retardancy, anti-static properties, etc.

Performance of medical surgical gowns

The performance of medical surgical gowns mainly includes: barrier performance, comfort performance. Barrier performance mainly refers to the protective performance of the surgical gown. Evaluation methods include hydrostatic pressure, water test, impact penetration, spray, blood penetration and microbial penetration, particle filtration efficiency. Comfort performance includes: breathability, water vapor permeability, drapability, quality, surface thickness, electrostatic properties, color, reflectivity, odor and skin sensitivity, as well as design and process effects. The main evaluation indicators are breathability, moisture permeability and charge density.

Structural design of surgical gowns

By setting a protective collar, it can provide warmth and protection to the neck of the surgical personnel. By setting the hand guard pocket, it is beneficial for the surgical staff to temporarily put their hands in the hand guard pocket when waiting intraoperatively, which plays a protective role and is more in line with the principle of aseptic operation and occupational protection.

By setting the contraction cuff, it helps to make the cuff fit the wrist, prevent the cuff from loosening, and avoid the gloves from slipping off during surgery and causing the surgical staff's hands to be exposed outside the gloves.

The design of the new humanized protective surgical gown is improved in the key areas of the gown, with double thickening in the forearms and two areas of the chest area and hand protection pockets in front of the chest and abdomen. By providing reinforcement sheets (double-layer structure) in the key areas, it helps to improve the ability of the gown to resist water penetration and enhance safety.
