Description

Technical Field

[0001] This invention relates to the field of medical technology, and in particular to a fully automated, high-volume, rapid infusion intelligent monitoring system. Background Technology

[0002] A Lancet study indicates that 15% of deaths in pre-hospital emergency care in China can be prevented by rapid infusion. For patients in shock, the mortality rate increases by 9% for every minute infusion is delayed; in cases of severe trauma, cardiac arrest, and other emergencies, a rapid infusion pathway must be established within 90 seconds. Every second of the "golden rescue window" is a matter of life and death.

[0003] However, the reality is far more severe than the data suggests. In pre-hospital emergency care and the transfer of critically ill patients, not only is it difficult to establish access after venous collapse, but the infusion rate is also slow, failing to meet the emergency needs for rapid resuscitation with large doses of fluids. Furthermore, there is no infusion monitoring system to ensure the safety of patients receiving infusion medications. Even when transferred to the hospital, the pressure, rate, and volume of the infusion are all monitored manually, which is inefficient. These problems are eroding the patient's hope for survival. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automated, high-capacity, rapid infusion intelligent monitoring system to solve the aforementioned problems in the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A fully automatic, high-capacity, rapid infusion intelligent monitoring system includes an infusion chamber, a motion module, a monitoring module, and a bone marrow aspiration infusion set. The infusion chamber has a first operating port and a second operating port on its two adjacent top and side surfaces, respectively. A baffle is vertically installed inside the second operating port, and a rotating shaft is spaced apart on the inner side of the baffle. A clamping plate is rotatably mounted on the rotating shaft corresponding to the baffle, so that when an infusion bag is placed on the clamping plate, the motion module at the top of the infusion chamber can drive the clamping plate to rotate around the rotating shaft and clamp it towards the baffle. A positioning hole is provided at the bottom of the baffle to limit the infusion bag interface. The monitoring module monitors the flow rate of the infusion tube connected to the infusion bag interface. The end of the infusion tube is connected to the puncture needle of the bone marrow aspiration infusion set.

[0006] The beneficial effects of this invention are as follows: A rapid bone marrow infusion pathway is quickly established using a bone marrow puncture infusion set. One end of the infusion tubing is connected to the puncture needle. The infusion bag is then placed on a clamp, with the bag's interface extending from a positioning hole. The other end of the infusion tubing is connected to the bag's interface. A motion module moves the clamp towards a baffle, squeezing the infusion bag on the clamp and pressurizing the medication to flow out from the bag's interface. A monitoring module monitors the medication flow rate in the infusion tubing in real time and adjusts the motion module's speed to regulate the pressure between the clamp and the baffle, thereby adjusting the medication flow rate. This system enables rapid pressurized infusion and medication flow monitoring, ensuring patient medication safety, reducing the workload of medical staff, and improving efficiency.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the motion module includes an electric push rod, a guide rod, a slider, and a rotating rod. A guide rod is provided at the lower part of the first operating port and is horizontally positioned pointing towards the second operating port. Electric push rods are spaced apart at the lower part of the guide rod. A slider is slidably sleeved on the guide rod. The output end of the electric push rod is fixedly connected to the bottom of the slider. One end of the rotating rod is rotatably positioned inside the slider, and the other end of the rotating rod is rotatably positioned in the rotating groove at the top of the clamping plate, so that the electric push rod can drive the clamping plate to close and clamp towards the baffle. The electric push rod is electrically connected to the speed controller.

[0009] The further beneficial effects of the above are as follows: the output end of the electric push rod drives the slider to slide along the guide rod towards the second operating port. While the rotating rod rotates around the slider, it pulls the clamping plate towards the baffle and clamps it, so that the infusion bag on the clamping plate is squeezed by the clamping plate and the baffle, and the medicine in the infusion bag flows out from the infusion bag interface under pressure. The speed controller controls the current of the electric push rod, thereby adjusting the power of the electric push rod, adjusting the running speed of the output end of the electric push rod, and thus controlling the pressure between the clamping plate and the baffle, and adjusting the flow rate of the medicine at the infusion bag interface.

[0010] Furthermore, heating wires are pre-embedded inside the clamping plate.

[0011] The further beneficial effect of adopting the above is that, while rapidly infusing the medication, the infusion bag can also be heated simultaneously by the heating wire, which avoids the local vasoconstriction outside the bone marrow caused by the low temperature of the medication, thus affecting the infusion rate.

[0014] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0015] Example 1 like Figures 1 to 12As shown, a fully automatic large-capacity rapid infusion intelligent monitoring system includes an infusion chamber 1, a motion module, a monitoring module 4, and a bone marrow aspiration infusion set 5. The top and side surfaces of two adjacent parts of the infusion chamber 1 are respectively provided with a first operation port 1-1 and a second operation port 1-2. A baffle 16 is vertically arranged inside the second operation port 1-2. A rotating shaft 17 is spaced apart on the inner side of the baffle 16. A clamping plate 15 is rotatably arranged on the rotating shaft 17 corresponding to the baffle 16, so that after the infusion bag 2 is placed on the clamping plate 15, the motion module at the top of the infusion chamber 1 can drive the clamping plate 15 to rotate around the rotating shaft 17 and clamp it together with the baffle 16. A positioning hole 161 is provided at the bottom of the baffle 16 to limit the infusion bag interface 21. The monitoring module 4 is used to monitor the flow rate of the infusion tube 3 connected to the infusion bag interface 21. The end of the infusion tube 3 is connected to the puncture needle 51 of the bone marrow aspiration infusion set 5.

[0016] A rapid bone marrow infusion pathway is quickly established using a bone marrow puncture infusion set 5. One end of the infusion tubing 3 is connected to the puncture needle 51, and then the infusion bag 2 is placed on the clamp 15. The infusion bag interface 21 extends from the positioning hole 161, and the other end of the infusion tubing 3 is connected to the infusion bag interface 21. The motion module moves the clamp 15 towards the baffle 16, squeezing the infusion bag 2 placed on the clamp 15, causing the medication in the infusion bag 2 to flow out under pressure from the infusion bag interface 21. The monitoring module 4 monitors the flow rate of the medication in the infusion tubing 3 in real time and adjusts the movement speed of the motion module to adjust the pressure between the clamp 15 and the baffle 16, thereby adjusting the flow rate of the medication. This system enables rapid pressurized infusion and medication flow monitoring, ensuring patient medication safety, reducing the workload of medical staff, and improving efficiency.

[0017] Example 2 This embodiment is a further improvement on embodiment 1, as detailed below: The motion module includes an electric push rod 11, a guide rod 12, a slider 13, and a rotating rod 14. A guide rod 12 is provided at the lower part of the first operation port 1-1, pointing to the second operation port 1-2 and horizontally positioned. Electric push rods 11 are spaced apart at the lower part of the guide rod 12. A slider 13 is slidably sleeved on the guide rod 12. The output end of the electric push rod 11 is fixedly connected to the bottom of the slider 13. One end of the rotating rod 14 is rotatably positioned inside the slider 13, and the other end of the rotating rod 14 is rotatably positioned in the rotating groove 151 at the top of the clamping plate 15, so that the electric push rod 11 can drive the clamping plate 15 to close and clamp towards the baffle 16. The electric push rod 11 is electrically connected to the speed controller 111. The output end of the electric push rod 11 drives the slider 13 to slide along the guide rod 12 toward the second operating port 1-2. While the rotating rod 14 rotates around the slider 13, it pulls the clamping plate 15 to close and clamp it toward the baffle 16, so that the infusion bag 2 on the clamping plate 15 is squeezed by the clamping plate 15 and the baffle 16, and the medicine in the infusion bag 2 flows out from the infusion bag interface 21 under pressure. The speed controller 111 controls the current of the electric push rod 11, thereby adjusting the power of the electric push rod 11, adjusting the running speed of the output end of the electric push rod 11, thereby controlling the pressure between the clamping plate 15 and the baffle 16, and adjusting the flow rate of the medicine in the infusion bag interface 21.

[0018] An electric heating wire 152 is pre-embedded within the clamp 15. During rapid infusion, the heating wire 152 simultaneously heats the infusion bag 2, preventing the medication from becoming too cold and causing local vasoconstriction outside the bone marrow, thus affecting the infusion rate. Specifically, the heating wire 152 can heat the medication in the infusion bag 2 to 25-37℃.

[0019] Example 3 This embodiment is a further improvement on embodiment 2, specifically as follows: The monitoring module 4 includes a flow monitoring sensor 43 clamped on the infusion tube 3 and a display screen 41 and a keyboard 42 disposed on the side wall of the infusion chamber 1. Both the flow monitoring sensor 43 and the keyboard 42 are electrically connected to the display screen 41. The flow monitoring sensor 43 includes a base 432 and a flap 431 rotatably disposed on the base 432. Semi-circular limiting grooves 433 are correspondingly formed in the middle of the flap 431 and the base 432. An ultrasonic counter-current transducer 4331 and an ultrasonic co-current transducer 4332 are staggered within the two limiting grooves 433. The flow monitoring sensor 43 monitors the flow rate of the medication in the infusion tube 3 and feeds the flow signal back to the display screen 41 for display, facilitating timely monitoring of the patient's infusion status by medical personnel.

[0020] The flow monitoring sensor 43 uses the time difference method to measure the volume of medicine passing through the cross-section of the inner wall of the infusion tube 3 per unit time; The inner diameter of infusion tube 3 is D, the path length of the ultrasonic wave is L, and the downstream velocity of the ultrasonic wave is t. d The countercurrent velocity is t uThe angle between the direction of ultrasonic wave propagation and the direction of fluid flow is θ. Due to the flow of the liquid, the time taken for ultrasonic waves to propagate a distance L downstream is shorter than the time taken to propagate upstream. This time difference can be expressed by the following formula: ; In the formula: c is the speed of sound of ultrasound in a non-flowing medium. V is the flow rate of the medicine solution. t u and t d The difference Δt between them is: ; In the formula, X is the distance between the ultrasonic countercurrent transducer 4331 and the ultrasonic concurrent transducer 4332 in the pipeline direction. Simplifying the above formula, the flow rate of the liquid medicine is a small amount compared to the speed of ultrasound in the medium; that is: ; The above formula can be further simplified to: ; That is, the flow rate V of the liquid medicine is: ; The flow rate of the liquid medicine is directly proportional to the time difference Δt between the downstream and upstream propagation of ultrasound. The flow rate Q of the liquid medicine is: ; The flow velocity V and flow rate Q of the drug solution in the infusion tube were measured over 3 unit time. In specific implementation, when the downstream flow velocity of the infusion ultrasound is t... d With countercurrent velocity t u At the same time, the built-in audible and visual alarm of the flow monitoring sensor 43 will sound an alarm, prompting medical staff to note that the infusion bag 2 is empty or the infusion tube 3 is bent, causing the flow to be interrupted.

[0021] Multiple sets of ultrasonic counter-current transducers 4331 and ultrasonic co-current transducers 4332 are respectively set in two limiting grooves 433. Multiple sets of measurements are taken, and the average value is taken to make the drug flow rate monitoring data more accurate.

[0022] Example 4 This embodiment is a further improvement on embodiment 3, as detailed below: A power module 18 is installed at the bottom of the infusion chamber 1. A speed controller 111, heating wire 152, flow monitoring sensor 43, keyboard 42, and display screen 41 are all electrically connected to the power module 18. The display screen 41 integrates a controller. Preset infusion flow rate and preset heating temperature are input via the keyboard 42. The controller in the display screen 41 controls the power of the speed controller 111 and heating wire 152, thereby controlling the infusion flow rate and heating temperature respectively. All data is displayed in real time on the display screen 41. In practical implementation, the display screen 41 has a built-in wireless signal output module that wirelessly connects to the wireless signal receiving module on the control host at the nurse station, sharing the data from the display screen 41 with the nurse station.

[0023] Example 5 This embodiment is a further improvement on embodiment 4, as detailed below: The puncture needle 51 of the bone marrow aspiration infusion set 5 is fitted with a needle core 51 or a bent cannula 53. One end of the bent cannula 53 has a sealing ring 531 on its outer wall to secure the inner wall of the needle seat 511 of the puncture needle 51. The other end of the bent cannula 53 has an external thread for connecting to the infusion tubing 3. After firing the bone marrow aspiration infusion set 5, the outer casing is removed, the needle core 52 is taken out from the needle seat 511 of the puncture needle 51, and then the bent cannula 53 is inserted. The puncture needle 51 is connected to the infusion tubing 3 through the bent cannula 53. The infusion tubing 3 can be adhered and fixed to the patient's skin, preventing the infusion tubing 3 from bending perpendicularly to the patient's skin and causing infusion interruption, thus further improving infusion safety. In practice, a 15G needle is used for bone marrow aspiration and infusion in adults, and the puncture depth depends on the insertion point: proximal tibia: 2.5cm, proximal humerus: 2.5cm, distal tibia: 2cm, distal radius: 1.5cm; an 18G needle is used for bone marrow aspiration and infusion in children, and the puncture depth depends on the child's age: 0-3 years: 0.5-1cm, 3-6 years: 1-1.5cm, 6-12 years: 1.5cm.

[0024] The splint 15, monitoring module 4, and motion module are each configured in two sets, each controlled by one of the two monitoring modules 4. This allows for simultaneous rapid pressurized infusion of two patients and two infusion bags 2, resulting in a higher degree of integration.

[0025] The first operating port 1-1 and the second operating port 1-2 are equipped with flip covers 19 that rotate outwards. When the infusion chamber 1 is not in use, the flip covers 19 can be closed to prevent dust from accumulating inside the infusion chamber 1.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
