Problems solved by technology

At present, there are two main ways to treat skin bacterial infection: (1) Apply antibacterial ointment to the affected area. This method has the disadvantages that the ointment dries quickly and the efficacy is not long-lasting; the antibacterial substances in the ointment are easy to volatilize into the surrounding environment; The germs in the surrounding environment cannot be blocked from contacting the affected area; the killing effect on the germs is not ideal; (2) the affected area is sprayed with antibacterial spray. In this way, the antibacterial substances cannot be all concentrated on the affected area during the spraying process, resulting in waste of liquid medicine; The sprayed antibacterial substances dry faster than smearing antibacterial ointment, and cannot produce lasting curative effect; the antibacterial substances are easily inhaled by the human body during the spraying process, irritating the respiratory tract, and causing discomfort; it cannot block the infection of the affected area by germs in the surrounding environment; it can kill germs Problems such as unsatisfactory effect

preparation example Construction

[0033] The present invention also provides the preparation method of antibacterial dressing described in above-mentioned technical scheme, comprises the following steps:

[0034] Mixing the sodium alginate solution and the antibacterial material to obtain the antibacterial sodium alginate solution;

[0035] The antibacterial sodium alginate solution is dropped into the aqueous solution containing calcium ions, and left to stand to obtain antibacterial liquid beads;

[0036] A plurality of the antibacterial liquid beads are separated and placed on the spunlace nonwoven base fabric, and then covered with the spunlace nonwoven fabric surface layer to obtain an antibacterial dressing.

[0037] The invention mixes the sodium alginate solution and the antibacterial material to obtain the antibacterial sodium alginate solution. In the present invention, the concentration of the sodium alginate solution is preferably 1-5 wt%, more preferably 3-4 wt%. In the present invention, the pr...

Embodiment 1

[0053] At room temperature, add sodium alginate into purified water and stir to completely dissolve the sodium alginate to obtain a 3% sodium alginate solution;

[0054] Adding nano-silver particles with a particle diameter of 50nm into the sodium alginate solution, stirring, so that the nano-silver particles are dispersed in the sodium alginate solution to obtain an antibacterial sodium alginate solution; the mass fraction of the nano-silver particles is 1%;

[0055] At room temperature, calcium chloride is added into purified water, stirred, and the calcium chloride is completely dissolved to obtain a calcium chloride solution with a mass fraction of 5%;

[0056] Use a syringe to drip the antibacterial sodium alginate solution into the calcium chloride solution, the inner diameter of the needle of the syringe is 2mm, and the dropping speed is 1 second / drop; stand for 3 minutes to react to obtain antibacterial liquid beads; the antibacterial liquid beads The diameter is 3~4mm...

Embodiment 2

[0062] At room temperature, add sodium alginate into purified water and stir to completely dissolve the sodium alginate to obtain a 3% sodium alginate solution;

[0063] Adding nano-zinc particles with a particle size of 50nm into the sodium alginate solution and stirring to disperse the nano-zinc particles in the sodium alginate solution to obtain an antibacterial sodium alginate solution; the mass fraction of the nano-zinc particles is 2%;

[0064] At room temperature, calcium chloride is added into purified water, stirred, and the calcium chloride is completely dissolved to obtain a calcium chloride solution with a mass fraction of 5%;

[0065] Use a syringe to drop the antibacterial sodium alginate solution into the calcium chloride solution, the inner diameter of the needle of the syringe is 1mm, and the dropping speed is 0.6 seconds / drop; stand for 3min to obtain antibacterial liquid beads; the antibacterial liquid beads The diameter is 1.5~2mm;

[0066] On the spunlace...

Abstract

The invention provides an antibacterial dressing and a preparation method thereof, and relates to the technical field of medical materials. According to the antibacterial dressing, antibacterial liquid beads are placed between a spunlaced non-woven base fabric and a spunlaced non-woven fabric cover layer and are broken under the stress condition, and due to the fact that the multiple antibacterial liquid beads are placed between the spunlaced non-woven base fabric and the spunlaced non-woven fabric cover layer, therefore, according to treatment requirements, a certain number of antibacterial liquid beads are crushed according to a certain time interval, so that the spunlaced non-woven base fabric with relatively strong hygroscopicity is permanently kept in a state of being infiltrated by the antibacterial liquid beads; and the spunlaced non-woven base fabric is in contact with the skin, so that germs infected parts of the skin can be continuously sterilized, and the sterilization effect is good.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to an antibacterial dressing and a preparation method thereof. Background technique [0002] When the human skin is infected with germs, symptoms such as itching and rashes will appear, which is contagious to a certain extent. At present, there are two main ways to treat skin bacterial infection: (1) Apply antibacterial ointment to the affected area. This method has the disadvantages that the ointment dries quickly and the efficacy is not long-lasting; the antibacterial substances in the ointment are easy to volatilize into the surrounding environment; The germs in the surrounding environment cannot be blocked from contacting the affected area; the killing effect on the germs is not ideal; (2) the affected area is sprayed with antibacterial spray. In this way, the antibacterial substances cannot be all concentrated on the affected area during the spraying process, resultin...
