In addition, the setting of the first release paper 2 can improve the convenience of use of the infusion hemostatic patch, which is beneficial to maintain the adhesiveness of the first adhesive sheet 3 and prevent the first adhesive sheet 3 from being polluted by unnecessary foreign matter.

Specifically, in this embodiment, the first adhesive sheet 3 is selected to use 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 cloth, and the hot-melt pressure-sensitive adhesive layer is arranged on the cloth. Bottom side, for achieving adhesion to the patient's skin. Of course, in addition to cloth, it is also possible to choose a sheet-like structure made of a material with obvious elasticity as the base layer, so that when the first adhesive sheet 3 is pasted on the patient's skin, the first adhesive sheet 3 can be stretched 3 Enlarging the bonding area between the first adhesive sheet 3 and the patient's skin to improve the firmness of the bonding.

Specifically, the sterilization and anti-inflammatory block 1 includes an adsorption layer and an anti-inflammatory layer arranged up and down. The adsorption layer is bonded on the first adhesive sheet 3. The adsorption layer is made of medical materials such as cotton fibers, which can absorb the fluid overflowing from the infusion needle hole. Blood, the anti-inflammatory layer is in contact with the first release paper 2, and the anti-inflammatory layer is provided with drugs capable of sterilizing and anti-inflammatory at the infusion needle holes, and the specific types of drugs are not limited here. After the first release paper 2 is torn off, 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 pinhole, in order to ensure hygiene and use safety, when producing the infusion hemostatic patch, it is necessary to sterilize and disinfect the sterilizing and anti-inflammatory block 1, specifically, the sterilizing and anti-inflammatory Block 1 was sterilized with ethylene oxide.

Specifically, the elastic pressing block 4 is a block structure made of elastic material, and the specific shape of the elastic pressing block 4 is not limited, for example, it may be cylindrical, cubic or other shapes. In this embodiment, the elastic material can be made of one or more of PAV sponge, rubber, wood pulp sponge or silica gel. PAV sponge is also called expansion sponge, which can expand after absorbing liquid, and wood pulp sponge It is called lignocellulose, which is an organic flocculent fibrous substance obtained from natural renewable wood through chemical treatment and mechanical processing. It has the characteristics of adsorption and expansion. When multiple elastic pressing blocks 4 are used, the elastic pressing block 4 is preferably arranged in a multi-layer structure, each layer adopts a different elastic material, and the deformation capacity of the elastic material located on the upper layer is smaller than that of the elastic material located on the lower layer. Therefore, it is ensured that the elastic pressing block 4 has a better pressure-resisting effect. The elastic pressing block 4 can press the sterilization and anti-inflammation block 1 below the first adhesive sheet 3 to a certain extent by its own gravity or under the action of an external force, so that the sterilization and anti-inflammation block 1 is in close contact with the skin at the infusion needle hole , thereby improving the healing speed of infusion pinholes.

Further, a water-permeable hole 31 is provided at the part where the first adhesive sheet 3 faces the sterilization and anti-inflammatory block 1. The water-permeable hole 31 can not only improve the air permeability of the whole infusion hemostatic patch, but also can be used on the sterilization and anti-inflammatory block 1 pair. The pressure of the skin at the infusion needle hole is too small, resulting in increased bleeding. When the sterilized and anti-inflammatory block 1 is soaked, the blood can pass through the first adhesive sheet 3 and enter the inside of the elastic pressing block 4, so that the elastic pressing block 4 absorbs blood and expands , increase the weight of the elastic pressing block 4 and improve the pressure of the elastic pressing block 4 on the sterilization and anti-inflammatory block 1, and then increase the pressure of the sterilization and anti-inflammatory block 1 on the skin at the infusion needle hole to achieve the purpose of hemostasis.

In order to ensure that the elastic pressing block 4 can produce a stable pressure on the sterilization and anti-inflammatory block 1 , in this embodiment, the elastic pressing assembly further includes a fixed shell 12 , an inverted tooth structure 11 and a pressing plate 10 . As shown in FIG. 5 , the bottom end of the fixed shell 12 is fixedly connected to the upper surface of the first adhesive sheet 3 , preferably by bonding. A plurality of elastic teeth of the inverted tooth structure 11 are arranged at intervals along the height direction of the fixed housing 12 on the inner wall of the fixed housing 12 , specifically, the plurality of elastic teeth may be linear or helical. Both the elastic pressing block 4 and the pressing plate 10 are arranged in the inner cavity of the fixed shell 12, the pressing plate 10 is arranged above the elastic pressing block 4, and the end of the pressing plate 10 abuts against the elastic teeth, and the fixed shell 12 is provided with a pressing port .

When the patient needs to stop the bleeding at the infusion needle hole after the infusion, the patient can press the finger on the pressure plate 10 through the pressure port and apply force downward, so that the pressure plate 10 moves downward along the height direction of the fixed shell 12 . When the pressing plate 10 moves downward, the elastic pressing block 4 is compressed, thereby giving a stable pressure to the sterilization and anti-inflammation block 1, so that the sterilization and anti-inflammation block 1 is stably pressed against the patient's infusion needle hole. When the pressure is in place, the patient can stop applying force. At this time, since the pressure plate 10 is located between two adjacent elastic teeth, the upper elastic teeth can restrict the upward movement of the pressure plate 10, thereby fixing the pressure plate 10. When the patient can loosen the pressing plate 10, the patient's hands are completely liberated.

Further, in order to facilitate the pressing plate 10 to move downward along the height direction of the fixed shell 12 . In this embodiment, the surface of the pressure plate 10 in contact with the teeth is set as an inclined plane, and the inclined plane is preferably parallel to the upper surface of the teeth. The specific inclination angle is not specifically limited here, and can be specifically set according to factors such as the manufacturing material of the tooth and the weight of the pressing plate 10 . In order to prevent the pressing plate 10 from moving upwards from adjacent teeth under the action of the elastic pressing block 4, the lower surface of the teeth is preferably set as a plane.

Further, according to the shape of the pressing plate 10, the fixed shell 12 can be composed of two oppositely arranged L-shaped plates, the L-shaped plate includes a tooth mounting portion and a flange portion, the teeth are fixed on the inner wall of the tooth mounting portion, and the flange is turned over. The edge is connected with the first adhesive sheet. Of course, it can also be composed of a cylinder with an open top and a flanging arranged at the bottom of the cylinder and turned outwards. In this case, the top opening of the cylinder is the pressing port. Of course, the fixed shell 12 can also be in other shapes, such as a cube shape. At this time, the pressing port can be arranged on the top of the fixed shell 12, or on the fixed shell 12 or the side wall.
