[0032] In clinical practice, bandages are commonly used to compress and stop bleeding on patients. During use, when using bandages to compress and stop bleeding, the size of the pressure is often difficult to control, and there is a problem of poor stability. In view of the above problems, the utility model provides a medical radial artery pressurized hemostatic ring and a medical early warning system, which achieve pressurized hemostasis for patients through air bags, and the size of the pressure is easy to control, with the advantage of high stability.

[0033] The technical solution of the present invention is described in detail below with reference to specific examples.

[0034] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model relates to a medical radial artery pressurized hemostatic ring, comprising an airbag 1, a fixing belt 2 and an inflation component. The airbag 1 comprises a hard portion 11 and an expansion portion 12, wherein the hard portion 11 is arranged outside the expansion portion 12 in an enclosing manner, and the expansion portion 12 is located at the bottom of the airbag 1, and is used to compress the needle hole of the patient. The end of the fixing belt 2 is connected to the hard portion 11, so as to be fixed around the patient's arm. The inflation component comprises an air pump 3, and the air pump 3 is connected to the expansion portion 12 in an air circuit.

[0035] It should be noted that, in this embodiment, the hard part 11 of the airbag 1 is used as a whole to guide the expansion direction of the expansion part 12. When the air pump 3 pumps gas into the expansion part 12, the hard part 11 limits the expansion part 12 to expand outward only at the bottom of the airbag 1. When the patient wears the fixing belt 2, the bottom of the airbag 1 just corresponds to the needle hole of the patient, thereby achieving the guiding effect. In addition, specifically, in this embodiment, the fixing belt 2 is specifically a hard cloth belt. During the installation process, the hard cloth belt can be put on the patient's arm.

[0036] Illustratively, when the hemostatic ring is used to apply pressure to stop bleeding on the radial artery of a patient, the fixing belt 2 is put on the patient's arm, and the expansion part 12 of the airbag 1 is aligned with the needle port position of the patient's radial artery, and then the air pump 3 is started to inflate the expansion part 12. The expansion part 12 expands toward the needle port position under the guidance of the hard part 11, so that the expansion part 12 compresses the needle port, and finally achieves compression hemostasis. Among them, the expansion size of the expansion part 12 can be adjusted by controlling the pumping volume of the air pump 3, and the pressure is easy to control, which has the advantage of high stability.

[0037] Specifically, in this embodiment, the inflatable component as a whole further includes a solenoid valve 4, which has an exhaust port 41, an air pump connection port 42, and an airbag connection port 43. The solenoid valve 4 has three positions. The normal position is that the exhaust port 41, the air pump connection port 42, and the airbag connection port 43 are all closed, the first communication position is that the air pump connection port 42 is connected to the airbag connection port 43, and the exhaust port 41 is closed, and the second communication position is that the air pump connection port 42 is connected to the exhaust port 41, and the airbag connection port 43 is closed.

[0038] Among them, the hemostatic ring also includes a controller and a control panel 5. The air pump 3 and the solenoid valve 4 are electrically connected to the controller. When the expansion part 12 needs to be inflated, the control panel 5 is operated, specifically, the inflation button is pressed. The controller starts the air pump 3 and connects the first connection position of the solenoid valve 4; after the expansion part 12 reaches the required inflation pressure value, the inflation button is released, the controller turns off the air pump 3, and the solenoid valve 4 returns to the normal position; when the expansion part 12 needs to be exhausted, the second connection position of the solenoid valve 4 is connected, the airbag connecting port 43 is connected to the exhaust port 41, and the airbag 1 is exhausted.

[0039] In one embodiment, the overall structure of the airbag 1 is further refined, and a guide hole 13 is provided at the bottom of the hard part 11 for the expansion part 12 to expand outward. When the air pump 3 is controlled to inflate the expansion part 12, the expansion part 12 can only expand outward through the guide hole 13 under the guidance of the hard part 11. The setting of the guide hole 13 can further optimize the expansion guiding effect of the hard part 11 on the expansion part 12.

[0040] In an extended embodiment, the gas circuit of the expansion part 12 is connected to an exhaust pipe, and a valve is arranged on the exhaust pipe. The arrangement of the exhaust pipe and the valve provides an additional exhaust method for the hemostatic ring. When the expansion part 12 needs to be exhausted, in addition to operating the control panel 5, the valve can also be operated to exhaust the expansion part 12 using the exhaust pipe.

[0041] In one embodiment, a mounting plate is fixedly arranged on the fixing belt 2, and the inflation assembly, the controller and the solenoid valve 4 are all arranged on the mounting plate. The mounting plate is a rigid structure as a whole, and the main components of the hemostatic ring are all fixedly arranged on the mounting plate. Since the fixing belt 2 is specifically made of soft material, the arrangement of the mounting plate can optimize the installation structure of the hemostatic ring, so that the components can be fixedly installed on the soft fixing belt 2 through the mounting plate.

[0042] In one embodiment, preferably, a pressure sensor 6 is provided on the expansion portion 12 to detect the pressure value of the expansion portion 12. At the same time, a controller and a display panel 7 are provided on the mounting plate, the pressure sensor 6 and the display panel 7 are both electrically connected to the controller, and the display panel 7 is used to display the pressure value of the pressure sensor 6.

[0043] Illustratively, the pressure sensor 6 can monitor the pressure value of the expansion part 12 in real time. During use, the real-time pressure value monitored by the pressure sensor 6 can be processed by the controller and displayed on the display panel 7. The patient wearing the device and the medical staff can understand the real-time pressure value of the expansion part 12 by observing the pressure data on the display panel 7, so that the medical staff can adjust the expansion pressure of the expansion part 12.

[0044] In this embodiment, it is more preferred that an alarm is also provided on the mounting plate, and a liquid sensor 8 is provided at the bottom of the expansion portion 12. The liquid sensor 8 is electrically connected to the controller, and when the liquid sensor 8 detects blood gushing out, the controller controls the alarm to sound an alarm.

[0045] It should be noted that, in this embodiment, the liquid sensor 8 is specifically used to detect whether there is blood flowing out of the needle hole of the radial artery. During the patient's wearing process, when an accident occurs and causes blood to flow out of the needle hole, the liquid sensor 8 will provide real-time feedback to the controller, and the controller will control the alarm to sound an alarm, so that medical staff can arrive at the scene in time for emergency treatment.

[0046] Specifically, the alarm includes at least one of an indicator light, a buzzer and an audible and visual alarm. In this embodiment, the alarm is specifically an audible and visual alarm, and the alarm is also fixedly mounted on the mounting plate.

[0047] In this embodiment, a protective cover is provided on the upper cover of the inflation component, and the controller, alarm, solenoid valve 4 and power supply are all installed inside the protective cover. In addition to protecting the components, the protective cover can also optimize the overall aesthetics of the hemostatic ring.

[0048] After the coronary angiography is completed, the radial artery pressurized hemostat needs to compress for twelve hours, and is required to release one milliliter of gas every two hours. In an extended embodiment, the controller presets the timing on and off time of the solenoid valve 4 to ensure that the pressurized pressure of the airbag 1 is slowly released until the pressure is completely released twelve hours after the operation. The specific setting can be based on actual conditions.

[0049] The utility model also provides a medical early warning system, including the medical radial artery pressurized hemostatic ring mentioned in the above scheme, and the medical early warning system also includes a mobile communication module and a mobile terminal. The controller is connected to the mobile communication module through a serial port, and the controller is connected to the set mobile terminal through the mobile communication module. When the liquid sensor 8 detects blood gushing, the controller controls to push alarm information to the mobile terminal.

[0050] It should be noted that the mobile terminal includes at least one of a smart phone, a tablet computer and a smart wearable device. In this embodiment, the alarm device is specifically an audible and visual alarm, and the alarm device is arranged in the nurse station, so when the alarm device sounds an alarm, the medical staff in the nurse station can respond in time.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
