Description

Technical Field

[0001] The present invention relates to the technical field of hemostatic devices, in particular to a portable air pressure adaptive hemostatic device. Background Art

[0002] In emergency hemostasis scenarios such as hospital emergency rooms, operating rooms, and outdoor rescue, especially when facing injuries and bleeding in special and critical areas such as the groin, traditional hemostasis methods expose many difficult-to-overcome defects.

[0003] In daily diagnosis and treatment in hospitals, for a large number of emergency trauma patients, the traditional manual compression method is extremely energy-consuming for medical staff. When faced with mass trauma incidents, limited medical resources make it difficult to provide continuous and effective compression to stop bleeding for many injured people at the same time, resulting in the inability to carry out hemostasis operations in a timely and comprehensive manner, delaying the optimal time for hemostasis for some patients. When using a manual binding tourniquet, due to the lack of a precise pressure control mechanism, the pressure adjustment depends entirely on the operator's experience. When the pressure is insufficient, it cannot effectively block the blood flow to the bleeding point, making it difficult to achieve a hemostasis effect; if the pressure is too high, it will hinder the blood circulation in the distal limbs, which may cause local tissue ischemia and necrosis for a long time, posing a serious hidden danger to the patient's subsequent recovery. In addition, manually operating a tourniquet is extremely difficult for non-professionals, such as ordinary people participating in first aid in emergency situations or medical assistants who have not received systematic first aid training. In a panic, it is difficult to master the appropriate binding force and pressing operation method, resulting in poor hemostasis effect in emergency hemostasis scenarios;

[0004] Furthermore, the components of existing devices that come into contact with the patient's skin are mostly fixed structures, making them difficult to quickly replace when used multiple times or for different patients. This can easily lead to infection risks due to cross-contamination, especially in germ-intensive environments like hospitals, where the risk is greater for patients with weaker immune systems. Furthermore, their fixed structure makes it difficult to adapt to patients of varying body sizes and bleeding patterns in various body parts. In irregular, highly mobile areas like the groin, they struggle to adhere tightly and provide effective compression, resulting in poor hemostasis adaptability. Therefore, a portable, adaptive pneumatic compression hemostasis device was proposed. Summary of the Invention

[0005] In view of this, the present invention provides a portable air pressure adaptive compression hemostasis device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the present invention is implemented as follows: a portable air pressure adaptive pressing hemostasis device includes a disc, an airbag is installed at the bottom of the disc, a piezoelectric sensor is installed at the bottom of the airbag, the top of the airbag is connected to an air supply pipe, one end of the air supply pipe passes through the disc, and a micro air pump is installed on the top of the disc, and the output end of the micro air pump is connected to one end of the air supply pipe.

[0007] Further preferably, a plurality of female buckles are evenly installed on the bottom of the disc, an annular patch is provided below the disc, a plurality of sub-buckles are evenly installed on the upper surface of the annular patch, the sub-buckles are snap-connected with the female buckles, and a hemostatic gauze is installed on the inner wall of the annular patch.

[0008] Further preferably, the upper surface of the disc is fixedly connected to a shell, and a control panel is installed on the top of the shell.

[0009] Further preferably, a battery is installed on the upper surface of the disc located inside the shell, a charging port is installed on the upper surface of the shell, and a buzzer alarm is installed on the upper surface of the shell.

[0010] The embodiment of the present invention adopts the above technical solution, which has the following advantages:

[0011] 1. The present invention is easy to use and operate quickly in environments such as hospital emergency rooms and wards, or in outdoor emergency situations, greatly shortening the hemostasis response time. It can be carried and used in a variety of scenarios. According to the changes in bleeding conditions in the groin, wrist, elbow, etc., the target pressure value can be automatically or manually adjusted on the control panel. The device responds and adjusts the airbag pressure in real time to adapt to the hemostasis needs at different stages. In the complex and changeable rescue environment of the hospital, it maintains a stable and efficient hemostasis effect, avoids tissue ischemia and hypoxic necrosis caused by excessive pressure or subcutaneous hematoma and inability to stop bleeding caused by insufficient pressure, thereby improving the accuracy and safety of hemostasis.

[0012] 2. The overall structure of the present invention is compact, small in size, and light in weight. The ring patch and hemostatic gauze are connected to the disc through a snap buckle, which is easy to replace. New consumables can be replaced in time after each use to avoid cross infection. At the same time, the device body can be reused, reducing the cost of use.

[0022] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-6 As shown, an embodiment of the present invention provides a portable air pressure adaptive compression hemostasis device, including a disc 1, an air bag 3 is installed at the bottom of the disc 1, a piezoelectric sensor 4 is installed at the bottom of the air bag 3, the top of the air bag 3 is connected to an air supply pipe 9, one end of the air supply pipe 9 passes through the disc 1, and a micro air pump 8 is installed on the top of the disc 1, and the output end of the micro air pump 8 is connected to one end of the air supply pipe 9.

[0025] In one embodiment, a plurality of female buckles 2 are evenly installed on the bottom of the disc 1, a ring-shaped patch 5 is provided below the disc 1, a plurality of sub-buckles 7 are evenly installed on the upper surface of the ring-shaped patch 5, the sub-buckles 7 are snap-connected with the female buckle 2, and a hemostatic gauze 6 is installed on the inner wall of the ring-shaped patch 5.

[0026] In one embodiment, a housing 11 is fixedly connected to the upper surface of the disc 1 , and a control panel 12 is mounted on the top of the housing 11 .

[0027] In one embodiment, a battery 10 is installed on the upper surface of the disc 1 inside the housing 11 , a charging port 13 is installed on the upper surface of the housing 11 , and a buzzer alarm 14 is installed on the upper surface of the housing 11 .

[0028] When the present invention is working: check the status of the device to ensure that the battery 10 has sufficient power, and can be charged in advance through the charging port 13; check whether the micro air pump 8, air supply pipe 9, air bag 3 and piezoelectric sensor 4 are connected intact and there is no leakage or damage; check whether the display of the control panel 12 is normal to ensure that the device can operate normally, and fix the new ring patch 5 with the female buckle 2 at the bottom of the disc 1 through the sub-buckle 7 to ensure a firm connection. At this time, the hemostatic gauze 6 on the inner wall of the ring patch 5 is in a clean state and can directly contact the hemostatic site. Clear the bleeding points in the groin, wrist, elbow and other parts, clean up the debris around the bleeding point to avoid affecting the sticking effect of the ring patch 5, and then put the ring patch 5 Accurately align the hemostatic gauze 6 with the bleeding point in the groin, wrist, elbow, or other areas, ensuring that the hemostatic gauze 6 completely covers the bleeding area. Firmly press the edge of the ring patch 5 to ensure it adheres tightly to the skin, ensuring that it does not shift during the application. Press the power button on the control panel 12 on top of the housing 11 to activate the device. Depending on the bleeding situation, select the appropriate hemostasis mode (e.g., automatic or manual) on the control panel 12. If automatic mode is selected, the device automatically adjusts the air pressure based on feedback from the piezoelectric sensor 4. Once the device is activated, the micro-pump 8 begins to operate, inflating the airbag 3 through the air supply tube 9. The airbag 3 expands and applies pressure to the bleeding point in the groin, wrist, elbow, or other areas. The piezoelectric sensor 4 monitors the compression pressure in real time and transmits the data to the control panel 12, which displays the current pressure value. When the pressure reaches the appropriate range, the inflation can be manually stopped through the control panel 12. If in automatic mode, the device automatically stops inflation or adjusts the air pressure based on the preset pressure threshold to achieve adaptive compression hemostasis. When the bleeding is effectively controlled, the buzzer alarm 14 sounds a beeping alarm, prompting the device to shut down.

[0029] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications and substitutions within the technical scope disclosed in the present invention, and such modifications and substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
