Description

Technical Field

[0001] The utility model relates to a hemostatic pressing patch, in particular to a hemostatic pressing patch with adjustable pressure. Background Art

[0002] Venipuncture is a common treatment and testing method in clinical practice. Venipuncture generally refers to puncturing a vein through a venous puncture needle to complete an infusion or puncture operation. After the treatment is completed and the needle is removed, the puncture site should be pressed appropriately to prevent bleeding. Currently, a cotton swab is generally used to press the puncture point in clinical practice to prevent continued bleeding from the blood vessel. It is generally necessary to press for about 5 minutes after the venous puncture needle is removed. Those with weak coagulation function need to appropriately extend the pressing time.

[0003] Although this pressing technique can be flexibly implemented according to the patient's physical condition, it still has the following defects:

[0004] 1. Since patients usually have not received special training, performing the pressing operation on their own can easily lead to adverse consequences. For example, pressing for too long or too short, or pressing too much or too little, will have a negative impact on the recovery of the skin and blood vessels at the puncture point, and may cause subcutaneous hematoma, cyanosis, or even retrograde infection causing complications such as phlebitis, resulting in poor safety.

[0005] 2. The pressing operation by medical staff will take a lot of time, especially for the unaccompanied nursing staff in the ICU. The labor cost is too high and it is difficult to implement in clinical practice.

When in use, when the tourniquet contacts the puncture site of the patient, the elastic pressing device is in an extended state, which pushes up the compression bag. At this time, the medical staff pulls the middle drawstring to compress the elastic pressing device. When the pressing force is appropriate, the fixing device on the middle drawstring is connected to the connecting piece, and the pressing force can be linearly controlled to ensure the hemostatic effect. Therefore, the design can accurately control the pressing force and ensure the hemostatic effect by matching the middle drawstring with the connecting piece, thereby effectively improving the safety of the compression hemostatic operation.

[0022] 3. In the utility model, a pressure-adjustable hemostatic pressing patch, the elastic pressing device includes a spring, a gasket and a pressing plate. The pressing plate is a flat disc structure, which can fit the patient's wound so as to accurately press the patient's puncture site. At the same time, when the patient's joint moves, the spring can be retracted to ensure that the pressure is continuous and uninterrupted. Therefore, this design can accurately and stably press the patient's puncture site through the flat disc structure pressing plate, effectively improving the hemostatic effect of the hemostatic pressing patch.

[0023] 4. In the utility model, the pressure-adjustable hemostatic pressing patch has a fixing device which is a medical adhesive. Both fixing devices are fixedly arranged at the bottom of the tourniquet. The medical adhesive can conveniently and quickly fix the hemostatic pressing patch on the human body, and the cost is low. Therefore, the design can conveniently and quickly fix the hemostatic pressing patch on the human body through the medical adhesive, effectively reducing the production cost and shortening the installation time of the hemostatic pressing patch.

[0024] 5. In the utility model, a pressure-adjustable hemostatic pressing patch has a fixing device of Velcro, and two fixing devices are fixedly arranged at the top and bottom of the tourniquet respectively.
