Description

Bleeding Hemostasis Feedback System

The present invention is a bleeding hemostasis feedback system, in particular, a bleeding hemostasis feedback system that can simulate wound bleeding, provide medical rescue trainees with accurate hemostasis training, and provide feedback on whether the operation is correct and the hemostasis effect is achieved.

According to the information, whether it is accidental collision, amputation, gunshot, cutting, puncture accident, etc., it is easy to cause the victim to go into shock or die due to excessive bleeding, poor hemostasis effect, etc., which makes the mortality rate of accidental trauma bleeding high. Therefore, in addition to reducing the occurrence of accidents, improving the ability of rescue personnel to successfully stop bleeding from wounds and reducing the occurrence of excessive bleeding are indeed issues that medical staff and medical practitioners are eager to improve.

In order to improve the above-mentioned shortcomings, some practitioners have designed training, simulation and teaching systems such as packing hemostasis training sets, wearable hemostasis training sets, trauma simulators, etc., so that trainees can practice correct hemostasis. However, it is found that the water used to simulate blood in the above-mentioned hemostasis training and simulation systems is mostly transported by a single motor, so that the amount of bleeding in the above-mentioned simulation systems is a single fixed state. Therefore, it is not possible to simulate arterial or venous bleeding. At the same time, because the motor delivery speed is fixed, it is not possible to simulate the intermittent bleeding of the injured due to the real heart rate, resulting in a monotonous training mode that does not conform to the actual situation. And because the liquid must be manually returned to its original place for standby after each hemostasis exercise, and cannot be automatically circulated and used continuously, it is difficult to learn. If the liquid has been completely discharged during the training, the trainee must pour it back in the middle of the training, which results in the training being interrupted. In particular, the above-mentioned simulation and training systems are not equipped with pressure and flow sensing components, so that the trainee cannot accurately know whether the appropriate pressure is applied to successfully stop the bleeding during the training, which makes it easy for the trainee to operate uncertainly, and when actually rescuing the injured, It is impossible to achieve effective and successful hemostasis, resulting in excessive blood loss to the injured. In addition, since the above simulation system is not equipped with a pulse simulation device, when the trainees practice with a tourniquet, they cannot confirm whether the pulse in the hemostasis state has stopped bleeding correctly. Therefore, the above simulation system is insufficient in simulation and cannot enable trainees to achieve the best training effect. This defect needs to be improved.

The purpose of the present invention is to improve the defects of the above-mentioned simulation system, so as to provide a bleeding hemostasis feedback system that can simulate wound bleeding, provide ambulance trainees with the opportunity to practice accurate hemostasis, and provide feedback on whether the operation is correct and whether the hemostasis effect is achieved.

To achieve the above-mentioned purpose, the hemostasis feedback system of the present invention includes a control element, a pulse width modulation element (PWM), a relay, a motor element, a water flow sensing element, a water pressure sensing element, a Bluetooth element, a power supply, a water storage tank and a simulated body; wherein: the control element is connected with the pulse width modulation element (PWM), the water flow sensing element, the water pressure sensing element, the Bluetooth element and the power supply to output a control signal to the pulse width modulation element (PWM), and can receive the signals transmitted by the water flow sensing element and the water pressure sensing element; the control element also uses the Bluetooth The components and the mobile device receive and transmit signals to each other; the pulse width modulation component (PWM) is electrically connected to the control component, the relay and the power supply.

The technical means and structures used by the present invention to achieve the purpose are described in detail as follows in conjunction with the embodiments shown in Figures 1 and 2:

As shown in FIG1 , the hemostasis feedback system of the present invention includes a control element 10, a pulse width modulation element (PWM) 20, a relay 30, a motor element 40, a water flow sensing element 50, a water pressure sensing element 60, a Bluetooth element 70, a power supply 80, a water storage tank 100 and a simulation body 200; wherein:

70與行動裝置300間相互接收、傳送訊號。 The control element 10 (see FIG. 1 ) is connected to the pulse width modulation element (PWM) 20, the water flow sensing element 50, the water pressure sensing element 60, the Bluetooth element 70 and the power supply 80 to output a control signal to the pulse width modulation element (PWM) 20 and receive signals transmitted by the water flow sensing element 50 and the water pressure sensing element 60. The control element 10 also uses the Bluetooth element

70 and the mobile device 300 receive and transmit signals to each other.

The pulse width modulation element (PWM) 20 (see FIG. 1 ) is electrically connected to the control element 10, the relay 30 and the power supply 80. The pulse width modulation element (PWM) 20 is used to receive the control signal transmitted by the control element 10 and transmit the control signal to the relay 30.

The relay 30 (see FIG. 1 ) is electrically connected to the pulse width modulation element (PWM) 20, the motor element 40 and the power supply 80. The relay 30 is used to receive the control signal transmitted by the pulse width modulation element (PWM) 20 and control the drive motor element 40 according to the control signal.

The motor element 40 (see FIG. 1 ) is electrically connected to the relay 30 and the power supply 80 . The motor element 40 is also connected to the water tank 100 and the simulation body 200 via the water pipe 41 . The motor element 40 can transfer the water in the water tank 100 to the simulation body 200 according to the control signal of the relay 30 to simulate the bleeding effect. The water outputted from the simulation body 200 can be recirculated and transferred to the water tank 100 .

The water flow sensing element 50 (see FIG. 1 ) is electrically connected to the control element 10 and the power supply 80 , and is used to detect the flow of the water pipe 41 connected to the motor element 40 , and to return the detected flow signal to the control element 10 .

The water pressure sensing element 60 (see FIG. 1 ) is electrically connected to the control element 10 and the power supply 80 , and is used to detect the pressure value of the water pipe 41 connected to the motor element 40 , and to return the detected pressure signal to the control element 10 .

The Bluetooth component 70 (see FIG. 1 ) is electrically connected to the control component 10 and the power supply 80 to provide mutual reception and transmission of signals between the control component 10 and the mobile device 300.

The power supply 80 (see FIG. 1 ) is electrically connected to the control element 10, the pulse width modulation element (PWM) 20, the relay 30, the motor element 40, the water flow sensing element 50, the water pressure sensing element 60 and the Bluetooth element 70 to provide power supply.

The water storage tank 100 (see FIG. 1 ) is used to store water and is connected to the water pipe 41 of the motor element 40 .

The simulated body 200 (see FIG. 1 ) is made of silicone material. The simulated body 200 is provided with a wound 201. The simulated body 200 is connected to the water pipe 41 of the motor element 40 so that the water in the water pipe 41 can be discharged from the wound 201 to simulate the bleeding effect.

Through the above structure, the mobile device 300 can be used to set the relevant control values, such as setting the fluid output per minute to arterial bleeding (such as: 150cc), venous bleeding (such as: 100cc), microvascular bleeding (such as: 30cc) or random bleeding, and setting the pulse width modulation element (PWM) 20, the frequency output of the relay 30, and the speed of the motor element 40, so as to simulate the prediction. The amount of bleeding, bleeding speed, etc. are set, and the hemostatic pressure value and the safe value of the fluid output are set at the same time; then, as shown in FIG2, the mobile device 300 is used to transmit the set control signal, and the control element 10 can receive the control signal of the mobile device 300 through the Bluetooth element 70, and transmit the control signal to the pulse width modulation element (PWM) 20, the relay 30 and the motor element 40, so that the motor The element 40 operates according to the control signal, and then the water in the water tank 100 is transported to the simulated body 200 according to the setting, and flows out from the wound 201 on the simulated body 200 to simulate the effect of human bleeding. Through the timing control of the pulse width modulation element 20 and the relay 30, the motor element 40 can simulate the heartbeat frequency and intermittently transfer the water from the simulated body 200 to the simulated body 200. In addition, the water flow sensing element 50 and the water pressure sensing element 60 of the present invention also transmit the detected flow signal and pressure signal to the control element 10 in real time, and the control element 10 transmits the detected flow signal and pressure signal to the mobile device 300 in real time using the Bluetooth element 70, so that the mobile device 300 can display the current flow rate and pressure in real time, and judge whether the overall flow rate has exceeded the set water output safety value.

Next, the trainee can stop bleeding at the wound 201 of the simulated body 200 (e.g., direct pressure hemostasis, bandage pressure hemostasis, etc.) to prevent water from flowing out of the wound 201. At this time, the flow rate and pressure are detected by the water flow sensing element 50 and the water pressure sensing element 60, and the flow rate and pressure signals are transmitted to the control element 10 for judgment. When the control element 10 determines that the pressure signal has indeed reached the hemostatic pressure value and maintained for a certain period of time, the control element 10 will stop bleeding. When the water flow rate does decrease, the control element 10 controls the driving motor element 40 to stop outputting water to the simulated body 200, and uses the Bluetooth element 70 to transmit the hemostasis success signal and the water output amount to the mobile device 300 for recording and display, and stops the motor element 40 and the servo motor 90 to complete the hemostasis exercise; then the motor element 40 circulates the output water back to the water storage tank 100 for use.

If the trainee stops bleeding from the wound 201 of the simulated body 200, the water flow sensing element 50 and the water pressure sensing element 60 detect the flow rate and pressure, and transmit the flow rate and pressure signals to the control element 10 for judgment; when the control element 10 judges that the pressure signal has not reached the hemostatic pressure value and the water flow rate has not changed, the control element 10 controls the driving motor element 40 to continuously output water to the wound 201 of the simulated body 200 until the set training time is reached or the water flow rate is not changed. After the output exceeds the set value, if the control element 10 determines that the pressure signal has not reached the hemostatic pressure value and the water flow rate has not changed, the control element 10 uses the Bluetooth element 70 to transmit the hemostasis failure signal and the water output to the mobile device 300 for recording and display, but the function will operate as usual until the person controls the pause through the Bluetooth element 70 to complete the hemostasis exercise; then the motor element 40 circulates the output water back to the water storage tank 100 for use.

Based on the above, the present invention further includes a servo motor 90, which is electrically connected to the control element 10 and the power supply 80. The servo motor 90 can simulate the beating of the pulse according to the control of the control element 10.

When the hemostasis exercise begins, the servo motor 90 starts to operate synchronously with the motor element 40 outputting water to simulate bleeding to simulate the pulse through the control signal of the control element 10; when the trainee performs the hemostasis exercise on the wound 201 of the simulated body 200 with a tourniquet, if the trainee operates correctly and the tourniquet does exert pressure on the wound 201 of the simulated body 200, the flow rate and pressure signals are transmitted to the control element 10 through the water flow sensing element 50 and the water pressure sensing element 60, and the control element 10 judges that the pressure signal has been When the hemostasis pressure value is reached and lasts for a period of time, and the water flow rate is reduced, the control element 10 controls the driving motor element 40 to stop outputting water to the simulated body 200, and controls the servo motor 90 to stop running. At this time, the control element 10 uses the Bluetooth element 70 to transmit the hemostasis success signal and the water output volume to the mobile device 300 for recording and display, and stops the motor element 40 and the servo motor 90, completing the correct hemostasis and pulse-free exercise, achieving the complete blood flow simulation of cutting off the artery and vein.

If the trainee fails to properly stop bleeding with a tourniquet at the wound 201 of the simulated body 200, the water flow sensing element 50 and the water pressure sensing element 60 transmit the detected flow signal and pressure signal to the control element 10. The control element 10 determines that the pressure signal has not reached the hemostatic pressure value and the water flow rate has not changed. The control element 10 controls the drive motor element 40 to continuously output water to the wound 201 of the simulated body 200, and the servo motor 90 continues to operate. After the time is up or the water output exceeds the set value, if the control element 10 determines that the pressure signal has not reached the hemostatic pressure value and the water flow rate has not changed, the control element 10 uses the Bluetooth element 70 to transmit the hemostasis failure signal and the water output to the mobile device 300 for recording and display, but the function will operate as usual until the person controls the pause through the Bluetooth element 70 to complete the hemostasis exercise; then the motor element 40 circulates the output water back to the water storage tank 100 for use.

Therefore, from the above description, it can be seen that the present invention has the following advantages:

(I) Since the present invention is provided with a pulse width modulation element (PWM) 20 and a relay 30, the motor element 40 can simulate the intermittent bleeding effect of the heart rate when outputting water, thereby increasing the difficulty and challenge of the students' hemostasis training and improving the success rate of hemostasis of actual wounds.

(ii) Since the present invention is provided with a water flow sensing element 50 for detecting water flow, it can stably calculate the blood output flow (such as arterial bleeding, venous bleeding, microvascular bleeding, etc.) and display it on the mobile device 300 in real time; at the same time, it can provide the control element 10 to determine whether the water output volume has exceeded the safety value (such as 1500 ml) as a judgment standard for whether the injury has reached the risk of massive bleeding; in addition, the water flow sensing element 50 of the present invention can also transmit the flow signal to the control element 10 in real time, and the control element 10 transmits it to the mobile device 300 in real time, so that the trainees can use the mobile device 300 to display the current flow signal in real time and adjust the processing speed in real time, thereby improving the accuracy and speed of hemostasis training.

(III) Furthermore, since the present invention is provided with a water pressure sensing element 60, it can provide students with detection and judgment when applying pressure to stop bleeding, and the water pressure sensing element 60 can transmit the detected pressure signal to the control element 10 for judgment, thereby improving the accuracy and rapidity of the hemostasis judgment; at the same time, the water pressure sensing element 60 of the present invention can also transmit the pressure signal to the control element 10 in real time, and the control element 10 can transmit it to the mobile device 300 in real time, so the students can use the mobile device 300 to display the current pressure signal in real time and can adjust the applied hemostasis pressure in real time, thereby improving the accuracy and completion of the hemostasis training.

(IV) In addition, since the present invention is provided with a servo motor 90, and the servo motor 90 is electrically connected to the control element 10, it can provide the effect of simulating pulse beating (such as: radial artery, dorsalis pedis artery, etc.). When students use a tourniquet to practice lower limbs, it is difficult to find the dorsalis pedis artery because it is located on the back of the sole of the foot. In addition, lower limb injuries are usually prone to heavy bleeding. Therefore, the servo motor 90 of the present invention can be used as a basis for students to judge whether the bleeding is stopped correctly and as a key point to confirm whether the beating has stopped. Compared with the hemostasis simulation system used for learning, which does not have a device for simulating pulse beating, the present invention is indeed highly practical and progressive.

(V) In addition, since the motor element 40 provided in the present invention can not only transport the liquid to the wound 201 of the simulated body 200, the motor element 40 can also immediately draw back the liquid flowing out of the wound 201 for circulation, so the trainees do not need to manually return the liquid for use. Therefore, the present invention can indeed save the time for returning the liquid, and has the advantages of saving time and labor and immediately drawing back the liquid.

(VI) Furthermore, since the present invention utilizes the Bluetooth component 70 to connect with the mobile device 300, the present invention can utilize the mobile device 300 to adjust and set relevant setting values and enable and disable controls in real time, and can display each detection value in real time, and record multiple data; therefore, the present invention is indeed convenient, fast and simple to control, and can store various values and performance records, so that each student can adjust his or her own hemostasis ability.

Therefore, this invention is indeed progressive and practical, and its method is indeed unprecedented, which truly meets the requirements for invention patents. Therefore, we have filed a patent application in accordance with the law and pray for the grant of the patent. I am very grateful.

However, the above is only a feasible embodiment of the present invention. The embodiment is mainly used to illustrate the technical means and structure used by the present invention to achieve the purpose. Therefore, it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the description of the present invention and the scope of the patent application should still fall within the protection scope covered by the present invention.
