[0002] With the development of medical technology, infusion patches have gradually replaced the previous adhesive tape, which is specially used for fixing needles and infusion tubes for infusion of hospital patients. When using a cannula needle, the existing infusion patches may cause blood reflux in the infusion needle, which requires pressurization to stop bleeding. The current infusion patches cannot stop bleeding well, and some infusion patches with pressurization structures cannot adjust the pressure according to needs, which has poor applicability and is not conducive to use.

[0003] The patent with application number 202122610815.X discloses an infusion patch with adjustable hemostatic pressurized pressure, which includes an adhesive tape, a sterile cotton block is arranged on one side of the adhesive tape, an adhesive layer is arranged on the adhesive tape on both sides of the sterile cotton block, and release paper is arranged on the outside of the adhesive layer and the sterile cotton block. It also includes a tearing head, a vent and a pressurizing mechanism, and the inside of the adhesive tape is provided with a pressurizing mechanism; the pressurizing mechanism includes an inner cavity and an inner thread, the inner cavity is arranged inside the adhesive tape, and a pressurized airbag is arranged in the inner cavity, one end of the pressurized airbag is connected to an inflation pipe passing through the adhesive tape, and one end of the inflation pipe is screwed with an inflation joint, an air supply pipe is arranged on the inflation joint, and one end of the air supply pipe is connected to an inflation ball, which is connected to the air supply pipe through a control valve. The utility model has a novel structure and ingenious conception, which is convenient for pressurized hemostasis when the infusion patch is in use, and the pressure can be adjusted as needed. It has strong applicability, and the inflation components can be reused to save costs.

[0004] The above-mentioned infusion patch has the following disadvantages when used: it is necessary to carry an additional inflatable ball for use, and because the pressurized airbag is located above the cotton block and the adhesive layer at the same time, after pressurization, the edge of the adhesive layer is prone to warping due to the expansion of the pressurized airbag, resulting in an unstable overall connection with the skin.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. A first chamber and a second chamber are opened inside the adhesive tape, and the first chamber and the second chamber are connected through a connecting pipe. When in use, the plastic ball shell of the connecting pipe is pressed to cause the barrier film to rupture, thereby achieving unblocked connection of the connecting pipe, and then part of the air in the second chamber enters the first chamber to achieve pressurized hemostasis for the patient. The overall structure is simple and convenient and quick to use;

[0013] 2. By setting the second chamber in a ring shape and being located above the adhesive layer, during use, the air pressure in the second chamber decreases, causing the cavity wall to shrink slightly, causing the entire adhesive layer to shrink synchronously, thereby making the overall adhesion more secure and improving the waterproof performance of the hemostatic area.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2 The utility model provides a technical solution: a pressurized hemostatic patch, comprising an adhesive tape 1 and a pressurizing mechanism arranged on the adhesive tape 1, a hemostatic pad 2 is arranged on the lower surface of the adhesive tape 1, a circle of adhesive layer 3 is arranged around the outer side of the hemostatic pad 2 of the adhesive tape 1, a peelable release layer 4 is arranged on the lower surface of the adhesive layer 3, and the pressurizing mechanism comprises a first chamber 5 and a second chamber 6 opened inside the adhesive tape 1, the first chamber 5 is located above the hemostatic pad 2, high-pressure air is injected into the second chamber 6, and the second chamber 6 is connected to the first chamber 5 through a connecting pipe.

[0020] The connecting pipe includes a first hose 7, a second hose 8 and a plastic spherical shell 9. The ends of the first hose 7 and the second hose 8 are connected to the interior of the first chamber 5 and the second chamber 6 respectively. The plastic spherical shell 9 is located between the first hose 7 and the second hose 8. The plastic spherical shell 9 is connected to the first hose 7 and the second hose 8 through a first vent hole 10 and a second vent hole 11 respectively, and the plastic spherical shell 9 is provided with a barrier film 12 inside the first vent hole 10.

[0021] The second chamber 6 is annular in shape as a whole and is arranged outside the first chamber 5 .

[0022] The second chamber 6 is entirely located above the adhesive layer 3 .

[0023] The upper and lower walls of the first chamber 5 are both made of transparent material.

[0024] Specifically, when using the utility model, tear off the release layer 4 on the lower surface of the adhesive layer 3, fix the adhesive tape 1 through the adhesive layer 3, and at this time press the plastic ball shell 9 to make the barrier film 12 inside the first vent hole 10 rupture under the action of pressure, and then the first chamber 5 is connected with the second chamber 6 through the first hose 7, the second hose 8 and the plastic ball shell 9, and then part of the air in the second chamber 6 enters the first chamber 5, causing the first chamber 5 to expand, thereby achieving pressurized hemostasis for the patient until the air pressure in the first chamber 5 and the second chamber 6 is in a balanced state.

[0025] In the above process, in the initial state, the second chamber 6 is fully expanded, causing the cavity wall of the second chamber 6 to be in a pull-rope state as a whole, that is, the adhesive layer 3 is flatly attached to the skin as a whole. After the air pressure is balanced, the air pressure in the second chamber 6 decreases, causing the cavity wall to shrink slightly, causing the adhesive layer 3 to shrink as a whole synchronously, thereby making the overall adhesion more firmly.

[0026] At the same time, since the upper and lower walls of the first chamber 5 are made of transparent material, the color of the hemostatic pad 2 can be quickly observed through the transparent part during use to judge the hemostatic effect.
