[0002] In current medical practice, especially during medical procedures that require skin puncture, such as injections or blood draws, medical staff usually need to take quick measures to prevent bleeding after removing the needle.

[0003] The traditional method involves placing cotton or a standard hemostatic patch on the needle wound and applying prolonged pressure to ensure effective bleeding. However, this method has significant limitations. First, manual pressure requires the medical staff or patient to maintain a steady hand and apply continuous force, which increases the burden on the medical staff or patient. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution of an automatic pressing hemostatic patch: it includes a patch 1, an adhesive layer 2, and a cotton layer 3; the adhesive layer 2 is arranged on the lower surface of the patch 1, and the cotton layer 3 is located in the middle of the patch 1; the adhesive layer 2 is used to stick to the skin, and the cotton layer 3 is made to correspond to the wound to stop bleeding.

[0025] Furthermore, an expansion component 4 is provided on the patch 1 to act on the cotton layer 3 so as to apply pressure to the cotton layer 3 so that the cotton layer 3 is pressed tightly against the wound to achieve the purpose of pressing to stop bleeding.

[0026] Preferably, the expansion assembly 4 includes a bubble capsule 41, a capsule opening 42, a one-way valve 43, a hard layer 44, and a soft layer 45; the capsule opening 42 is provided on the bubble capsule 41; the bubble capsule 41 covers the hard layer 44 to form an air inlet chamber A; the hard layer 44 is located above the soft layer 45 to form an air storage chamber B; the one-way valve 43 is mounted on the hard layer 44 to connect the air inlet chamber A to the air storage chamber B in one direction; and the cotton layer 3 is fixed to the soft layer 45. Thus, when the bubble capsule 41 is pressed, the gas in the air inlet chamber A enters the air storage chamber B through the one-way valve 43, causing the air storage chamber B to expand, thereby causing the soft layer 45 to swell, and the cotton layer 3 to be pressed tightly against the wound.

[0027] Furthermore, the bag opening 42 is connected to the air inlet cavity A, and the outside air enters the air inlet cavity A through the bag opening 42. When the bubble bag 41 is pressed, the finger will block the bag opening 42 to prevent the air in the air inlet cavity A from escaping from the bag opening 42.

[0028] Furthermore, in order to enhance the expansion effect of the soft layer 45 , the hard layer 44 is made of hard PVC material, and the soft layer 45 is made of soft PVC material; thus, when the air storage cavity B expands, the soft layer 45 will be more easily deformed by stress.

[0029] Furthermore, in order to reduce the backflow of air in the air storage chamber B to the air inlet chamber A, in one embodiment, the one-way valve 43 includes a valve body 431, an air inlet 432, a limiting ring 433, and a valve 434; the air inlet 432 is connected to the air inlet chamber A and is discharged from the valve 434 to the air storage chamber B; the limiting ring 433 is fixed in the valve body 431, and the valve 434 is located below the limiting ring 433; there are three valves 434 distributed around the circumference, and the valves 434 are tilted and fixed on the valve body 431; the three valves 434 are staggered to form a variable Air outlet S; the limiting ring 433 is in the shape of a fence, and the limiting ring 433 limits the top of the valve 434; in this way, air enters from the air inlet 432, and is pressurized on the valve 434 through the limiting ring 433. Since the valve 434 is made of soft PP material, it will disperse downward after being stressed. During this period, the variable air outlet S is connected, so that the gas can smoothly enter the air storage chamber B; and after the pressure on the air bubble stops, the gas in the air storage chamber B pressurizes the valve 434, which will cause the valve 434 to disperse upward, but the valve 434 is affected by the limiting ring 433 and cannot disperse. During this period, the variable air outlet S is sealed to achieve the purpose of air storage.

[0030] Working principle: Medical staff place the cotton layer 3 against the patient's wound, stick the adhesive layer 2 to the skin to fix it, and then block the bag opening 42 with their fingers to press the bubble bag 41, squeezing the gas in the air inlet chamber A into the air storage chamber B through the one-way valve 43. The soft layer 45 is pressurized and expanded, and the cotton layer 3 is pressed tightly against the wound.

[0031] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
