Description

A kind of silicone gel applicator and its using method and application

technical field

The invention belongs to the field of medical applicators, and in particular relates to a silica gel applicator and a method and application thereof.

Background technique

Wound treatment is carried out by wiping the wound lightly and changing the dressing, and the use of the dressing becomes the direct treatment method for wound treatment. After skin injury, it is usually necessary to use a skin substitute medical dressing to protect the wound, prevent wound infection and severe dehydration, provide a moist environment conducive to wound healing, and promote wound healing.

Cotton pads and gauze are the earliest and most widely used types of dressings. The advantage is that the wound exudate is quickly absorbed, and the production and processing process is relatively simple. The disadvantage is that the permeability is too high, which is easy to dehydrate the wound surface and stick to the wound surface. When replacing, it will cause mechanical damage again, resulting in wound bleeding, edema, etc., and increase the probability of passage of microorganisms in the external environment, resulting in wound infection. , time-consuming, increase the patient's pain.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a silicone gel applicator and its use method and application, so as to solve the technical problems that the existing cotton pad adheres to the wound surface, causes mechanical damage again when replacing, and easily passes through the microorganisms in the external environment.

In order to achieve the above object, a kind of silicone gel applicator of the present invention and the specific technical scheme of its using method and application are as follows:

A silicone gel applicator, comprising a release paper layer, one side of the release paper layer is sequentially provided with a wound contact layer, a diversion layer, an intermediate absorption layer and a waterproof protective layer, and two sides of the wound contact layer are arranged in sequence. It is respectively bonded with the release paper layer and the guide layer, and the adhesive force between the release paper layer and the wound contact layer is smaller than the adhesive force between the wound contact layer and the guide layer and the skin;

The peripheries of the diversion layer and the waterproof protective layer are bonded together by ultrasonic heat sealing, and an intermediate absorption layer is sandwiched between the connected diversion layer and the waterproof protective layer, and the wound contact layer prevents adhesion. wound; the guide layer guides the exudate into the middle absorption layer quickly and evenly; the middle absorption layer contains superabsorbent resin material, which quickly absorbs and locks the liquid without reverse osmosis; the waterproof protective layer is used to prevent liquid ooze.

Further, the areas of the release paper layer, the wound contact layer, the flow guiding layer and the waterproof protective layer are equal and larger than the area of the middle absorbing layer.

Further, the wound contact layer is made of transparent material, so as to indirectly observe the healing of the wound.

Further, the wound contact layer is made of silicone gel material, the guide layer is made of SS non-woven fabric, and the intermediate water absorbent layer is made of Super Absorbent Polymer. SAP is a new type of functional polymer material. It has a high water absorption function that absorbs water hundreds to thousands of times heavier than itself, and has excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even if it is pressurized. Therefore, it is widely used in various fields such as personal hygiene products, industrial and agricultural production, civil construction, etc. The waterproof protective layer is made of SMS non-woven materials. SMS non-woven English is: Spunbond+Meltblown+Spunbond Nonwovens are composite Spun cloth, a composite product of spunbond and meltblown, has the advantages of high strength, good filtration performance, no adhesive, and non-toxicity. At present, it is mainly used for medical and health labor protection products such as surgical gowns, surgical caps, protective clothing, hand washing clothes, handbags, etc.

A method of using a silicone gel patch, comprising the following steps, and the following steps are performed in sequence:

Step 1. Routinely clean and disinfect the wound and surrounding skin, remove the necrotic material in the wound area, and dry it with sterile gauze and cotton balls;

Step 2, select a suitable size of silicone gel to apply on the wound surface, so that it can cover at least centimeters of skin around the wound;

Step 3. When using, peel off the release paper layer, then stick the wound contact layer on the wound, and press gently to make the edge of the silicone gel application closely fit the skin;

Step 4. Place an indirect absorbent dressing on the silicone gel applicator and fix it with appropriate fixing parts;

Step 5. Determine the replacement cycle of the silicone gel applicator according to the specific conditions of the wound or skin.

Further, the indirect absorbent dressing is a gauze sheet or a foam dressing.

Further, for cavitary wounds, silicone gel patches are used in combination with alginate.

Further, for leg ulcers, a silicone gel patch is combined with a pressure bandage for pressure therapy.

Application of a silicone gel patch for acute and chronic wound care with moderate to severe exudation.

The silicone gel applicator of the present invention and its using method and application have the following advantages: large liquid absorption capacity, strong liquid locking ability, no reverse osmosis during extrusion, dry surface and no exudation at the bottom layer; High fluid rate, using new polymer materials combined with unique product design, can be professionally used for acute and chronic wound care with moderate to severe exudation; does not adhere to wet wounds, but adheres gently to the surrounding skin; Reduce the trauma to the wound surface during replacement and reduce pain. It can be pasted repeatedly without deformation, displacement, falling off, transparent, and easy to fix to help wound healing.
