Problems solved by technology

Although common surgical gowns have good antibacterial and barrier capabilities, the liquid splashed on the gown tends to slide down along the gown and drip to the ground, which reduces the non-slip friction of the ground and increases the contact of medical staff. Liquid, risk of exposure to microorganisms

preparation example Construction

[0053] Second aspect of the present invention proposes a kind of preparation method of composite biological enzyme surgical suit, and preparation step comprises:

[0054] (1) Dissolving the inorganic antibacterial agent and the additive in the solvent and stirring evenly to obtain the antibacterial colloid A;

[0055] (2) adding biological enzymes supported by inorganic particles, stirring evenly to obtain antibacterial colloid B;

[0056] (3) Coating the antibacterial colloid B on the nonwoven fabric, and drying to obtain the surgical gown.

[0057] Preferably, the solvent is deionized water.

[0058] Preferably, the drying temperature in the step (3) is 30-60°C.

[0059] Preferably, the preparation steps include:

[0060] (1) dissolving nano-silver, silver-loaded nano-silica, polylactic acid, and chitosan in deionized water, and stirring evenly to obtain antibacterial colloid A;

[0061] (2) Add mesoporous silica loaded with thrombin, and stir evenly in the dark to obtai...

Embodiment 1

[0067] The first aspect of the present invention proposes a composite biological enzyme surgical gown. The raw materials include 1 part of nano-silver, 3 parts of silver-loaded nano-silica, 1 part of mesoporous silica loaded with thrombin, and 5 parts by weight. Part chitosan, 5 parts polylactic acid, 85 parts deionized water, non-woven fabric.

[0068] Wherein the preparation method of the mesoporous silica loaded with thrombin is as follows:

[0069] (1) Add 1 part of mesoporous silica to deionized water, add 1 part of dopamine, stir evenly in the dark, and centrifuge to obtain dopamine-loaded mesoporous silica;

[0070] (2) Add 1 part of dopamine-loaded mesoporous silica to deionized water, add 1 part of thrombin, stir in the dark, and centrifuge to obtain thrombin-loaded mesoporous silica.

[0071] Among them, silver-loaded nano-silica was purchased from Shanghai Carboxyphene Biomedical Technology Co., Ltd., the model is Ag-MSNs-50.

[0072] The nano-silver is obtained b...

Embodiment 2

[0083] The first aspect of the present invention provides a composite bio-enzyme surgical gown, and the second aspect of the present invention provides a method for preparing the composite bio-enzyme surgical gown. The specific implementation is the same as in Example 1. The difference is that the raw materials include 2 parts of nano-silver, 2 parts of silver-loaded nano-silica, 3 parts of mesoporous silica loaded with thrombin, 6 parts of chitosan, 4 parts of polylactic acid, 85 parts by weight. parts deionized water, non-woven fabric.

Abstract

The invention provides a composite biological enzyme surgical gown and further provides a preparation method of the composite biological enzyme surgical gown. The surgical gown is prepared from the following raw materials of nano silver, silver-loaded nano silicon dioxide, thrombin-loaded mesoporous silicon dioxide, chitosan, polylactic acid, deionized water and a non-woven fabric. Through the combined action of various raw materials, the mechanical strength of the surgical gown and the attaching capacity of an inorganic antibacterial agent and biological enzyme are improved, and the surgical gown is endowed with excellent sterilization and virus killing effects.

Description

technical field [0001] The invention relates to the field of surgical gowns, in particular to a composite biological enzyme surgical gown and a preparation method thereof. Background technique [0002] During surgical operations, it is necessary to ensure that surgical gowns, surgical instruments, and the environment are sterile, and surgical gowns are the main barrier between medical staff and patients. After continuous reform and development, surgical gowns have developed a variety of non-woven surgical gowns from the most primitive cotton surgical gowns, including polyethylene polyester surgical gowns, polypropylene spunbond surgical gowns, and composite nonwoven surgical gowns. These surgical gowns have the functions of antibacterial, antiviral and protective. [0003] During the operation of medical staff, the medical staff have to face the patient's blood, body fluids and secretions that may contain viruses or bacteria, and there is a risk of infection at any time. Th...
