The negative pressure bag 32 is fixedly connected to the flexible insulation layer 9, the liquid absorption cotton 33 is arranged inside the negative pressure bag 32, the second water permeable pad 34 is fixedly connected to the bottom of the thermal pad 28, and the second capillary hose 35 is embedded in the second water permeable pad 34; the second capillary hose 35 is fixedly connected to the second liquid absorption tube 36, and the second liquid absorption tube 36 is away from the second capillary hose One end of 35 is fixedly connected to the negative pressure bag 32 through a second solenoid valve 37, and a liquid extraction pump 38 is fixedly connected to the negative pressure bag 32; a flexible temperature sensor 39, a flexible humidity sensor 40 and a flexible pH sensor 41 are fixedly connected to the surface of the second permeable pad 34; the injection component includes a needle tube connector 42, an infusion tube 43 and a capillary outlet tube 44, one end of the infusion tube 43 is fixedly connected to the needle tube connector 42 through a one-way valve 45, and the other end of the infusion tube 43 is connected to the capillary outlet tube 44, and the capillary outlet tube 44 is embedded in the interior of the second permeable pad 34.

[0054] In this embodiment, the flexible pH sensor 41 can monitor the pH value in real time and determine whether a large amount of sweat is produced, which serves as a condition for activating the second liquid-absorbing component.

[0055] Specifically, the camera component includes a bracket 46 and a camera 47 fixed on the bracket 46. The bracket 46 is fixedly connected to the negative pressure bag 32 by Velcro.

[0056] In this embodiment, the camera 47 captures images and sends them to the image data processing module. Through image comparison, it is determined whether bleeding occurs, especially at the puncture point. When bleeding is detected, the second pressure-applying component around the bleeding location immediately supplies air to expand the punching airbag 27 to compress and stop bleeding.

[0057] A method for using a forearm hematoma compression device for use after coronary angiography, for use with the aforementioned forearm hematoma compression device for use after coronary angiography, comprising the following steps: prior to contrast injection, fixing the patient's hand and forearm with a joint fixation component and a forearm fixation component, and then performing contrast injection; assembling an arm back support component and a cold compress component to form an annular structure, wherein the two cold compress components can be spliced ​​together as needed; injecting water into the cold compress component and cooling it, stopping cooling after a period of cooling, and, after the temperature stabilizes, sleeved on the patient's coronary angiography puncture site, wherein the arm back support component is located on the back of the arm;

[0058] Gas is injected into the supporting airbag so that the first liquid absorbing component, the second liquid absorbing component and the medicine injection component are in contact with the forearm skin, and the cold compress component compresses and cools the forearm hematoma; after receiving the liquid absorption instruction, the first liquid absorbing component and the second liquid absorbing component absorb the liquid on the forearm skin, and the camera component is correspondingly arranged on the second liquid absorbing component at the corresponding puncture point, and collects the image of the second liquid absorbing component in real time. When bleeding is detected, an alarm is issued through the terminal; the medicine injection component injects detumescent medicine during the detumescence stage to perform medical detumescence.

[0059] Before contrast injection, the patient places the back of their forearm on the first permeable pad 5, the back of their hand on the palm support 58, and grips the U-shaped frame 60. They tighten the first threaded ring 61, squeezing the U-shaped frame 60 to secure it. The first electric push rod 49 then extends, moving the required distance to adjust the length of the telescopic rod 52. The second electric push rod 50 is then angled toward the patient's forearm via the hinged seat. The second electric push rod 50 extends, allowing the silicone squeeze pad 54 to adhere to the skin surface, which is then further secured with the fixing elastic band 57.

[0060] After the angiographic injection is completed, the medical staff will apply pressure to the injection point. In order to better stop bleeding, appropriate pressure can be applied through the wrist fixing structure. The specific process is: the position of the arc frame 65 is adjusted by the limit shell 6202 and the sliding cross bar 6203, and the I-shaped sliding block 66 can move on the arc frame 65 to make the extrusion silicone pad 70 correspond to and contact the bandaging area, and then the electrorheological fluid in the liquid storage bag 69 is energized to change it from liquid to solid, thereby fixing the rectangular shell 68, and squeezing the arc clip 72 through the third threaded ring 73 to achieve clamping and fixing of the extension rod 67.

[0061] In addition, during the hemostasis process, an ice patch can be placed on the forearm and fixed by the elastic band 57 to reduce swelling in the early stage, and then a cold compress can be used to reduce swelling in the later stage.

[0062] Depending on the needs, choose cold compress components of different sizes to accommodate the patient's forearm diameter. During assembly, align the first fixing ring 11 on one side of the flexible cold compress array cavity with the second fixing ring 12 on the support cotton 1, and insert the fixing rod 13 to achieve fixation. Then, water is injected into the flexible cold compress array cavity through the infusion component. In the initial stage, one infusion component is responsible for liquid supply and the other for exhaust. Once the liquid supply is completed, the flexible cold compress array cavity is filled with water.

[0063] Power is supplied to the cooling element, causing the semiconductor cooling plate 23 near the micro motor 24 to cool the water. Simultaneously, the motor drives the ice scraper 25 to rotate, scraping off frost from the surface of the semiconductor cooling plate 23. When all the drive motors are rotating, the frost flows. After a period of cooling, the cooling stops to prevent freezing inside the flexible cold compress array cavity, creating an ice-water mixture inside.

[0064] After power is turned off and the temperature on one side of the second pressure-applying component drops, place the cold compress component on the inner forearm at the location of the hematoma. Place the support pad 1 on the back of the forearm and secure it with the first and second fixing rings 11 and 12 on the other side. To ensure a tight fit and achieve hematoma compression, fill the support airbag 2 with gas, causing it to expand and reduce the space.

[0065] Furthermore, to ensure that each location reaches the preset pressure, the pressure values ​​collected by each pressure sensor are first collected and compared with the target pressures stored in the database. If the pressure is insufficient, the corresponding second pressure-applying component applies pressure. Specifically, gas is injected into the gas distribution pipe 30, and the first solenoid valve 31 at the location where pressure is required is opened. The gas enters the ram bag 27 through the gas pipe 29, inflating the ram bag 27 and increasing the pressure. If the pressure is insufficient, the air can be released by deflation.

[0066] After the pressure adjustment is complete, a cold compress can be applied to reduce swelling. The ice-water mixture in the flexible cold compress chamber 10 cools the thermal pad 28 and the second permeable pad 34 via the semiconductor refrigeration sheet 23 and the thermally conductive aluminum sheet 26. Because the ice-water mixture cools steadily, it can achieve global cooling of the forearm, preventing localized cooling from causing arm discomfort. Of course, the flexible cold compress chamber 10 can also contain water other than an ice-water mixture, and a relatively low temperature of water, such as 10 degrees Celsius, to prevent discomfort caused by excessively low temperatures.

[0067] After global cooling through ice-water mixture or lower temperature water, formal cold compress compression and swelling reduction begins. According to the location of the hematoma, determine in advance which flexible cold compress chambers 10 correspond to the hematoma location. According to the preset program, the refrigeration components and the second pressure-applying components at these locations are controlled to operate. The refrigeration components are intermittently powered, and the semiconductor refrigeration plate 23 close to the heat-conducting aluminum plate 26 cools on one side and heats on the other side. The semiconductor refrigeration plates 23 at other locations provide auxiliary cooling to ensure that the temperature difference with the hematoma area is not too large, causing discomfort. The temperature sensor 39 can monitor the temperature in real time to achieve temperature control.

[0068] The ice-water mixture or water at a lower temperature in the flexible cold compress cavity 10 can be cooled. After a period of time, one of the two infusion parts is responsible for supplying liquid and the other is responsible for draining liquid to replace the liquid and ensure the normal operation of the semiconductor refrigeration plate 23.

[0069] Because cold compresses last for a relatively long time, potentially over an hour, the skin may sweat and become excessively moist, necessitating liquid suction to prevent discomfort. A humidity sensor detects surface humidity. When the humidity reaches a set threshold, the corresponding second absorbent element begins to absorb liquid, while the first absorbent element continues to absorb liquid at a set frequency.

[0070] Negative pressure is applied to the collecting pipe 147, and liquid is aspirated through the first liquid aspiration pipe 6. The liquid pump 38 creates negative pressure inside the negative pressure bag 32, opening the second solenoid valve 37. The second liquid aspiration pipe 36 and the second capillary hose 35 draw sweat into the negative pressure bag 32, where the absorbent cotton 33 absorbs the sweat. Simultaneously, the camera 47 captures images and sends them to the image data processing module. Through image comparison, it determines whether bleeding is occurring, particularly at the puncture point. If bleeding is detected, the second pressure-applying component around the bleeding site immediately supplies air, inflating the ram airbag 27 to apply pressure to stop the bleeding.
