[0036] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0037] First embodiment

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a pressure tourniquet regulated according to a patient's blood pressure provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the structure of the tourniquet shown; Figure 3 for Figure 1 A top view of the tourniquet is shown; Figure 4 for Figure 3 A pressure tourniquet adjusted according to the patient's blood pressure, comprising:

[0039] A tourniquet body 1 and a controller body 11, wherein a first Velcro 2 is provided on the surface of the tourniquet body 1, and a sponge pad 3 is bonded to the surface of the first Velcro 2;

[0040] A waterproof film 4, wherein the number of the waterproof films 4 is two, and the two waterproof films 4 are respectively connected to the upper and lower sides of the surface of the tourniquet body 1;

[0041] A connecting belt 5, the connecting belt 5 is connected to one end of the tourniquet body 1, and a second Velcro 6 is sewn on the surface of the connecting belt 5;

[0042] A third Velcro 7, wherein the third Velcro 7 is sutured to the surface of the tourniquet body 1;

[0043] A connecting ring 8 is connected to one end of the tourniquet body 1 through a connecting strip.

[0044] A mounting head 13 is connected to one side of the tourniquet body 1 , and a connecting tube 9 is connected to one end of the mounting head 13 .

[0045] One end of the connecting pipe 9 is connected to a connecting head 10 , and the connecting head 10 is connected to the controller body 11 .

[0046] Blood pressure measurement of the controller body 11:

[0047] Direct measurement: Generally, the tourniquet body 1 is equipped with an invasive blood pressure monitoring module. By inserting an arterial catheter into the artery, the pressure change in the artery is directly measured. The patient's systolic blood pressure, diastolic blood pressure, mean arterial pressure and other data can be obtained in real time and accurately. This method is mainly used in some critical surgeries or scenarios with extremely high requirements for blood pressure monitoring accuracy.

[0048] Indirect measurement: In most cases, smart pressure tourniquets use indirect measurement methods, such as the oscillometric method, which uses an inflated cuff to block limb arterial blood flow and then slowly deflates it. Blood pressure is calculated by monitoring the pressure changes in the cuff and the oscillation waves generated by arterial blood flow. This method is easy to operate and suitable for most clinical scenarios. The smart tourniquet can be built with a measurement module similar to an electronic sphygmomanometer to achieve this.

[0049] Pressure value calculation

[0050] Basic pressure setting: The pressure of the tourniquet is usually determined based on the patient's systolic blood pressure. Generally speaking, the pressure of the tourniquet needs to be higher than the systolic blood pressure to effectively block blood flow and achieve the purpose of hemostasis. In practical applications, the initial pressure is often set by adding a certain safety margin to the systolic blood pressure. For example, for general patients, 30-50 mmHg may be added to the systolic blood pressure as the initial pressure setting value of the tourniquet.

[0051] Consider individual differences: factors such as the patient's age, weight, limb circumference, and vascular condition will affect the hemostatic effect and tolerance to tourniquet pressure. For the elderly, children, or patients with vascular diseases, their blood vessels are less elastic or more fragile, and the degree of pressure increase needs to be appropriately reduced. For patients with well-developed muscles and thicker limbs, it may be necessary to appropriately increase the pressure value on the basis of the above.

[0052] Dynamic adjustment: The smart pressure tourniquet will also dynamically adjust according to the patient's physiological changes during the hemostasis process. For example, if the patient's blood pressure fluctuates due to surgical stimulation, blood loss, etc., the tourniquet will monitor the blood pressure changes in real time and adjust the pressure value accordingly to ensure that effective hemostasis is always maintained while avoiding damage to tissues caused by excessive pressure.

[0053] Pressure control

[0054] Feedback regulation mechanism: The intelligent pressure tourniquet monitors the pressure inside the tourniquet in real time through a pressure sensor, and feeds back the pressure data to the control chip. The control chip compares the actual pressure value with the target pressure value calculated based on the blood pressure. When the actual pressure is lower than the target pressure, the control chip instructs the air pump to inflate the tourniquet to increase the pressure; conversely, when the actual pressure is higher than the target pressure, the control chip controls the deflation valve to deflate appropriately to reduce the pressure, thereby achieving precise control of the tourniquet pressure.

[0055] Safety protection mechanism: To prevent excessive pressure from causing harm to the patient, smart pressure tourniquets usually also have an upper pressure limit. Even if the pressure value calculated based on blood pressure exceeds this upper limit, the tourniquet will only maintain the pressure at the upper limit and issue an alarm to alert medical staff so that they can take timely measures to adjust.

[0056] A plurality of air bags are installed inside the tourniquet body 1 and connected by a hose, so as to facilitate the delivery and extraction of gas through the connecting tube 9 and the controller body 11 .

[0057] Two waterproof films 4 are used to protect the tourniquet body 1 from liquid.

[0058] The sponge pad 3 is used to increase the comfort level when the tourniquet body 1 is tied.

[0059] The working principle of a pressure tourniquet provided by the present invention that is adjusted according to the patient's blood pressure is as follows:

[0060] During use, when the patient's wound is to be hemostatically controlled, the sponge pad 3 is first bonded to the surface of the tourniquet main body 1 through the first Velcro 2. After the sponge pad 3 is bonded, the tourniquet main body 1 is placed on the patient's wound. Then, one end of the tourniquet main body 1 is sleeved on the surface of the connecting ring 8 through the connecting belt 5 with the second Velcro 6, and the connecting ring 8 is reversely sleeved to pull the tourniquet main body 1 to fix it to the position of the patient's wound. Then, the second Velcro 7 on the surface of the connecting belt 5 is bonded and fixed to the third Velcro 7 on the surface of the tourniquet main body 1. After the tourniquet main body 1 is fixed, the connector 10 at one end of the connecting tube 9 is connected to the controller main body 11. Finally, the patient's blood pressure is transmitted to the controller main body 11 for selection of pressure values. After the specified value is selected, the controller main body 11 is started to use the connecting tube 9 to vacuum the tourniquet main body 1 to stop the bleeding of the patient's wound.

[0061] Compared with the related art, the pressure tourniquet provided by the present invention that is adjusted according to the patient's blood pressure has the following beneficial effects:
