Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a non-invasive internal carotid artery blood flow monitoring and management instrument. Background Art

[0002] Acute ischemic stroke (AIS) is a common cerebrovascular disease in clinical practice in my country, accounting for about 3 / 4 of cerebrovascular diseases, and has a very high disability rate. Intravenous thrombolysis and intravascular interventional therapy can quickly achieve vascular recanalization, restore brain tissue reperfusion, and improve clinical prognosis. It is currently the preferred treatment strategy for AIS patients. However, although a considerable proportion of patients have achieved vascular recanalization, complications such as postoperative hypoperfusion and intracranial hemorrhage still occur, which seriously affects the recovery of patients' neurological function and prognosis. Some studies have shown that perioperative blood pressure management is an especially important independent factor affecting postoperative prognosis, but some studies have shown that the use of antihypertensive drugs to lower blood pressure within 48 hours of onset does not reduce the death or severe disability of patients at 14 days or discharge. Because there are many factors that affect blood pressure values, it is extremely important to monitor and adjust cerebral blood flow before and after surgery.

[0003] At present, the existing technologies for monitoring cerebral blood flow and intracranial vascular blood supply status of AIS patients after surgery mostly use head CT, magnetic resonance imaging and vascular imaging tests a certain period of time after surgery, and then formulate corresponding treatment and nursing plans based on the test results. In addition, the patient's body position management, volume and blood pressure management are artificially controlled according to the surgical location and test results, so as to achieve the patient's body position adaptation to the recovery state and the appropriate state of cerebral blood perfusion.

[0004] At present, the existing technology uses regular inspections to obtain monitoring results and blood pressure values ​​for the state of brain blood circulation, and then combines the results with treatment experience to manage the patient's body position, volume and blood pressure. This method cannot monitor the brain's blood flow in real time and continuously, nor can it perform real-time synchronous body position management or volume and blood pressure management based on the monitored brain blood flow. As a result, it is impossible to accurately perform effective body position, volume and blood pressure management, and it is impossible to obtain real-time effect data of body position, volume and blood pressure management, which leads to poor monitoring and management effects. In addition, manual body position management is not only inconvenient to operate, but also not accurate enough in management operations. Blood pressure management is affected by stroke volume, heart rate, peripheral resistance, elasticity of the aorta and large artery walls, circulating blood volume and vascular capacity. Therefore, manual body position management, volume and blood pressure management may not accurately supply blood to the ischemic area of ​​the brain after surgery, affecting the rehabilitation effect, and even causing excessive blood supply to rupture blood vessels in the surgical area or insufficient perfusion, resulting in a significant increase in the risk of recurrent infarction. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a non-invasive internal carotid artery blood flow monitoring and management instrument, which solves the problem in the prior art that there is a lack of a detection and management structure that can simultaneously monitor blood flow and adjust body position, volume and blood pressure in real time according to blood flow monitoring data to achieve a safe recovery range of blood flow data, resulting in the inability to accurately and automatically manage body position and blood pressure and volume according to blood flow data in real time, resulting in untimely discovery and processing, and ultimately resulting in the inability to monitor and adjust the blood supply recovery effect in real time, poor treatment and nursing effects, and harm to patients.

[0034] like Figure 1-10 As shown, an embodiment of the present invention is: a non-invasive internal carotid artery blood flow monitoring and management instrument, including a body position management bed 1, the body position management bed including an anti-collision bed head 2, a rotating connecting rod 3 is fixedly arranged on the left side of the anti-collision bed head, the rotating connecting rod is fixedly connected to the central monitoring controller 39, a supporting bed frame 4 is fixedly arranged at the bottom of the anti-collision bed head, the supporting bed frame is a metal frame composed of four columns and four beams, a body position control combined bed board 5 is arranged in a partition on the top of the supporting bed frame, the body position control combined bed board includes a backrest board group 6, a hip board group 7, a leg board group 8 and a foot board group 9, the backrest board group is composed of a left backrest board 10, a middle backrest board 11 and a right backrest board 12, the hip board group is composed of a left hip back board 13, a middle hip board 14 and a right hip board 15, the leg board group is composed of a left leg board 16, a middle leg board 17 and a right leg board 18, The footrest group consists of a left footrest 19, a middle footrest 20 and a right footrest 21. Hand guards 22 are fixedly arranged on the left and right sides of the supporting bed frame, a movable operating table top 23 is arranged on the top of the hand guards, and an electric position adjustment frame 24 is fixedly arranged at the bottom of the position management bed. The electric position adjustment frame is fixedly arranged inside the supporting bed frame. The electric position adjustment frame includes a left steering deflection frame 25, a right steering deflection frame 26, an upper steering deflection frame 27 and a lower steering deflection frame 28. The left steering deflection frame is fixedly connected to the left backrest and the left hip board through a left deflection connecting rod 29, the right steering deflection frame is fixedly connected to the right backrest and the right hip board through a right deflection connecting rod 30, the upper steering deflection frame is fixedly connected to the left backrest, the middle backrest and the right backrest through an upper deflection connecting rod 31, and the lower steering deflection frame is fixedly connected to the middle leg board through a lower deflection connecting rod 32.

[0035] An ultrasonic blood flow monitoring collar 33 is fixedly installed in the neck area of ​​the position management bed, and a flexible line belt 34 is fixedly installed on the right side of the anti-collision bed head, and the top of the flexible line belt is fixedly connected to the ultrasonic blood flow monitoring collar. The ultrasonic blood flow monitoring collar includes a spring steel bracket 35, a flexible sheath 36 is wrapped around the outside of the spring steel bracket, a vertebral basilar artery Doppler ultrasonic blood flow sensor 37 is fixedly installed in the middle of the flexible sheath, and a carotid artery Doppler ultrasonic blood flow sensor 38 is fixedly installed on the right side of the flexible sheath. The central monitoring controller is connected to the electric position adjustment frame and the ultrasonic blood flow monitoring collar through lines.

[0036] When implementing this embodiment, the patient is firstly subjected to ultrasonic blood flow monitoring neck collar wearing to monitor the patient's blood flow data before undergoing cerebral infarction surgery, and the patient's blood flow data of the change of body position is obtained in conjunction with the body position adjustment of the body position management bed, wherein the blood flow data includes blood flow velocity and blood flow volume. After the patient undergoes cerebral infarction surgery, the patient is placed on the body position management bed for rehabilitation management. After the patient lies on the body position management bed, the ultrasonic blood flow monitoring neck collar is worn on the patient's neck. Since the middle part of the ultrasonic blood flow monitoring neck collar is a spring steel bracket, it is forcibly opened and then placed on the patient's neck. After releasing the hand, the memory retraction function of the spring steel will make the ultrasonic blood flow monitoring neck collar firmly worn on the patient's neck, so that the vertebral basilar artery Doppler ultrasonic blood flow sensor and the carotid artery Doppler ultrasonic blood flow sensor can be closely attached to the vertebral basilar artery and carotid artery of the patient, and the corresponding blood flow data monitoring is completed. The blood flow data monitoring here includes the monitoring of blood flow velocity and flow volume.

[0037] After completing the wearing monitoring of the ultrasonic blood flow monitoring collar, the real-time monitoring and real-time body position control settings are fully started. When the blood flow velocity or flow detected by the ultrasonic blood flow monitoring collar is abnormal, that is, it is not within the standard value range set in the central monitoring controller, the central monitoring controller controls the electric body position adjustment frame to rotate and adjust the body position control combined bed board so that the patient is driven to adjust the body position. For example, when the patient's left sleeping position compresses the heart and causes abnormal blood supply to the brain, it is manifested as a decrease in the blood flow velocity and flow of the vertebral basilar artery and the carotid artery. At this time, the central controller controls the left steering deflection frame to start driving the left deflection connecting rod to drive the left backrest board and the left hip board to rotate, thereby raising the left side of the bed board and driving the patient to deflect to the right, so that the patient is placed on the right side or lying flat to promote the patient's brain blood supply to return to normal.

[0038] This embodiment provides a blood flow monitoring and management instrument that has a real-time brain blood flow monitoring structure, an automatic synchronous adjustment structure for body position, and a monitoring and management data storage structure. It uses an ultrasonic blood flow monitoring neck cuff to monitor the neck blood flow data in real time, and combines the central controller to analyze and transmit real-time instructions to control the body position management bed to adjust the patient's body position, which is conducive to achieving accurate and real-time accurate and automated body position management and volume and blood pressure management based on blood flow data, improving the treatment and nursing effects, and ensuring patient safety. In addition, the real-time recording of blood flow data and body position data and the corresponding rehabilitation effects is conducive to obtaining the specific influence relationship data of body position data and blood flow data on rehabilitation prognosis, thereby improving the postoperative treatment and rehabilitation data of brain AIS, and laying a data foundation for more scientific and accurate postoperative treatment and rehabilitation treatment plan exploration.

[0039] In this embodiment, a flexible mattress is fixedly arranged on the top of the body position control combined bed board, which is beneficial to improving the patient's lying comfort.

[0040] In this embodiment, an anti-fouling cover is provided on the outside of the flexible sheath, which helps to prevent the sheath from being contaminated and corroding the internal device.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
