Example 1
The present embodiment provides an infusion hemostatic patch, as shown in fig. 1 and 2, which includes a sterilizing and anti-inflammatory block 1, a first release paper 2, a first adhesive sheet 3, and an elastic pressing assembly. The sterilizing and anti-inflammatory block 1 is a main component of the transfusion hemostatic patch and is used for sterilizing and anti-inflammatory skin at a transfusion needle hole. The first release paper 2 is arranged below the sterilizing and anti-inflammatory block 1 and is in contact with the lower bottom surface of the sterilizing and anti-inflammatory block 1, the first adhesive sheet 3 is adhered above the sterilizing and anti-inflammatory block 1, and the sterilizing and anti-inflammatory block 1 is positioned between the first adhesive sheet 3 and the first release paper 2. The first adhesive sheet 3 and the first release paper 2 are both long-strip-shaped, the lengths of the first adhesive sheet 3 and the first release paper 2 are both larger than the length of the sterilizing and anti-inflammatory block 1, and the part of the first adhesive sheet 3 protruding out of the sterilizing and anti-inflammatory block 1 is adhered to the part of the first release paper 2 protruding out of the sterilizing and anti-inflammatory block 1, so that the sterilizing and anti-inflammatory block 1 is fixed between the first adhesive sheet 3 and the first release paper 2, and the first adhesive sheet 3 and the sterilizing and anti-inflammatory block 1 can be exposed after the first release paper 2 is torn down before the transfusion hemostatic patch is used. The elastic pressing component comprises an elastic pressing block 4, the elastic pressing block 4 is arranged above the first adhesive sheet 3 and is opposite to the sterilizing and anti-inflammatory block 1, and the elastic pressing block 4 can generate certain pressure on the sterilizing and anti-inflammatory block 1 under the action of self gravity or other external forces, so that the sterilizing and anti-inflammatory block 1 can generate certain pressure on an infusion needle hole, and the aim of pressing the skin at the infusion needle hole of a patient is fulfilled.
Compared with the prior art, after transfusion is finished, a patient or other people need to hold the sterilized cotton ball to press the skin at the transfusion needle hole so as to reduce the bleeding amount, in the embodiment, the sterilizing and anti-inflammatory block 1 can be pressed at the needle hole under the pressing of the elastic pressing block 4 by arranging the elastic pressing block 4, so that the skin at the transfusion needle hole of the patient is pressed, sterilized and anti-inflammatory, the bleeding amount at the needle hole can be reduced, the healing speed of the needle hole is improved, the hands of the patient are liberated under the premise of ensuring the pressing effect, the freedom of movement of the patient is improved, and the situation that other people need to help to press is avoided. In the infusion process of a patient, the infusion hemostatic patch can be adhered to the skin of the patient by using the first adhesive sheet 3, so that the sterilization and anti-inflammatory block 1 and the elastic pressing block 4 are fixed at the infusion needle, the infusion needle can be limited to a certain extent, and the needle running phenomenon is avoided. In addition, the arrangement of the first release paper 2 can improve the use convenience of the transfusion hemostatic patch, is favorable for keeping the adhesiveness of the first adhesive sheet 3 and avoids the first adhesive sheet 3 from being polluted by unnecessary foreign matters.
Specifically, in this embodiment, the first adhesive sheet 3 is selected to be a medical adhesive tape, the medical adhesive tape includes a base material layer and a hot-melt pressure-sensitive adhesive layer, the base material layer is a fabric, the fabric may be made of a medical adhesive tape material such as a nonwoven fabric, and the hot-melt pressure-sensitive adhesive layer is disposed on the bottom surface of the fabric, for achieving adhesion with the skin of a patient. Of course, a sheet-like structure made of a material having a remarkable elasticity may be selected as the base material layer in addition to the cloth, so that the adhesive area between the first adhesive sheet 3 and the skin of the patient is increased by elongating the first adhesive sheet 3 when the first adhesive sheet 3 is adhered to the skin of the patient, thereby improving the firmness of the adhesion.
Specifically, the sterilizing and anti-inflammatory block 1 comprises an adsorption layer and an anti-inflammatory layer, wherein the adsorption layer is adhered to the first adhesive sheet 3, the adsorption layer is made of medical materials such as cotton fibers and can adsorb overflowed blood at the infusion needle hole, the anti-inflammatory layer is abutted to the first release paper 2, medicines capable of sterilizing and diminishing inflammation at the infusion needle hole are arranged on the anti-inflammatory layer, and the type of specific medicines is not limited. After the first release paper 2 is torn, the medicine on the anti-inflammatory layer can leak out. Since the sterilizing and anti-inflammatory block 1 needs to be in direct contact with the skin at the needle hole, in order to ensure sanitation and use safety, the sterilizing and anti-inflammatory block 1 needs to be sterilized, in particular, the sterilizing and anti-inflammatory block 1 is sterilized by using ethylene oxide when producing the transfusion hemostatic patch.
Specifically, the elastic pressing block 4 is a block structure made of an elastic material, and the specific shape of the elastic pressing block 4 is not limited, and may be, for example, a cylindrical shape, a cubic shape, or other shapes. In this embodiment, the elastic material may be made of one or more of PAV sponge, rubber or wood pulp sponge, and when the elastic material is made of rubber, silica gel is preferable. PAV sponge is also called as expansion sponge, which can expand after absorbing liquid, wood pulp cotton is also called as lignocellulose, is an organic flocculent fibrous substance obtained by processing natural renewable wood through a chemical treatment mechanical method, and has the characteristic of absorbing and expanding.
