Detailed implementation manners

[0039] To make the objectives, technical solutions and advantages of the present application clearer and more definite, the following further describes the present application in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] Currently, frequent blood sampling by doctors for blood glucose monitoring not only brings serious physical and psychological traumas to patients and takes a lot of time of medical staff, but also medical staff usually only collect fingertip blood glucose information. The measurement accuracy of fingertip blood glucose detection is not as good as that of venous blood glucose, which affects the accuracy of treatment. In addition, a large amount of human resources are required for monitoring, reporting and adjusting treatment plans, resulting in low efficiency. Therefore, the present application solves the above problems through the following embodiments.

[0041] As Figure 3 、 Figure 4As shown in the figure, this embodiment proposes an intelligent monitoring and treatment device for acute diabetic complications, which mainly includes: an indwelling component 100, a photoelectric sensor 500, a control host 600, and an automatic injection component 700. The indwelling component 100 includes an indwelling needle hose 120. The indwelling needle hose 120 is inserted into the patient's blood vessel, such as the patient's vein. The indwelling component 100 is inserted into the patient's blood vessel through the indwelling needle hose 120 and remains on the patient. The photoelectric sensor 500 is connected to the indwelling needle hose 120 and extends out of the indwelling component 100 or is housed in the indwelling component 100 within the blood vessel. The photoelectric sensor 500 is used to detect physiological parameter information in the blood. During the specific process, before the indwelling needle hose 120 enters the blood vessel, the photoelectric sensor 500 contracts within the indwelling needle hose 120, which facilitates the insertion of the indwelling component 100 into the blood vessel; when the indwelling needle hose 120 enters the blood vessel and it is necessary to detect the blood parameters within the blood vessel, the photoelectric sensor 500 extends out of the indwelling needle hose 120 and can be in full contact with the blood within the blood vessel, so that the detected physiological parameter information is more accurate. The control body is arranged outside the patient and is communicatively connected to the photoelectric sensor 500, and receives the physiological parameter information sensed by the photoelectric sensor 500; the control host 600 can be a processor, which can be communicatively connected to the photoelectric sensor 500 in a wired or wireless manner. In this embodiment, a cable can be passed through the indwelling component 100, with one end electrically connected to the photoelectric sensor 500 and the other end extending outside the patient and electrically connected to the control host 600 (if communication is not possible, the other end extends outside the patient and is connected to a wireless module for wireless communication), to achieve a relatively stable data communication function. The automatic injection component 700 is connected to the indwelling component 100 and injects insulin into the blood vessel through the indwelling component 100 under the drive of the control host 600. The automatic injection component 700 is arranged outside the patient and can be a micro-injection pump, an automatic insulin injection pump, etc. The control host 600 calculates and adjusts the injection volume and infusion rate of the automatic injection component 700 according to the physiological parameter information sensed by the photoelectric sensor 500. Therefore, the control host 600 regularly obtains the patient's physiological parameter information through the photoelectric sensor 500 at a set time, analyzes and judges whether the patient's current blood sugar is stable based on the physiological parameter information, and thus controls the injection volume and / or injection frequency of insulin in the automatic injection component 700 to make the patient's physiological indicators reach normal or stable levels.

[0042] An intelligent monitoring and treatment device for acute diabetic complications in the present application is inserted into the patient's blood vessel through an indwelling needle hose 120, and the indwelling component 100 is left on the patient's body, which can keep the indwelling needle hose 120 stable in the blood vessel for a long time. After the indwelling needle hose 120 is inserted into the blood vessel, the photoreceptor 500 on the indwelling needle hose 120 extends out of the indwelling needle hose 120 and is used to detect physiological parameter information in the blood. The control host 600 outside the patient receives the physiological parameter information sensed by the photoreceptor 500. The control host 600 analyzes according to the physiological parameter information sensed by the photoreceptor 500, controls the automatic injection part 700 to inject insulin into the blood vessel through the indwelling component 100 according to the patient's physiological indicators, and adjusts the injection amount and infusion rate of the automatic injection part 700 according to the periodically detected physiological parameter information. By adopting this intelligent monitoring and treatment device, it is possible to monitor physiological parameter information such as the patient's blood glucose, blood ketone, renal function, and electrolytes in real time, and automatically adjust the injection of insulin. This intelligent monitoring and treatment device integrates a variety of advanced technologies, which can effectively reduce the patient's trauma, improve the accuracy of treatment, avoid the doctor's frequent blood sampling operation on the patient, and save medical and nursing human resources.

[0043] As Figure 1 , Figure 3 shown, further, the control host 600 can be integrally set with the automatic injection part 700, or the control host 600 can be separately set in the main body case outside the human body. A wireless communicator is also set in the main body case, and the wireless communicator is electrically connected to the control host 600. The wireless communicator can be wirelessly communicatively connected to both the photoreceptor 500 and the automatic injection part 700, and is used to enable the control host 600 to wirelessly receive the detection signal of the photoreceptor 500 and send and receive the control information of the automatic injection part 700. The wireless communicator can also be used to upload the detection data to the cloud platform, doctor terminal, or / and patient terminal in real time to remotely monitor the patient's health status. When the photoreceptor 500 monitors the key physiological parameter information such as the patient's blood glucose, blood ketone, renal function, and electrolytes in real time or periodically. The data of the physiological parameter information is transmitted to the control host 600 or a smart phone through the wireless transmission technology (such as WiFi or Bluetooth) of the wireless communicator. Not only is the data analyzed through the preset program of the control host 600, but also the doctor and the patient's smart phones can view it in real time, and the doctor can analyze according to the data of the patient's physiological parameter information. When the data of the physiological parameter information is uploaded to the cloud platform in real time, the doctor can remotely monitor the patient's health status and adjust the treatment plan when necessary. This function is especially suitable for critically ill patients who need long-term monitoring.

[0044] The control host 600 automatically calculates based on the data of physiological parameter information monitored in real time or at regular intervals and issues a control instruction to the automatic injection unit 700 to adjust the insulin infusion rate and control the insulin injection amount. Thus, a closed-loop feedback system is formed to ensure that the patient's blood sugar decreases and stabilizes. Moreover, the control host 600 not only records the data of physiological parameter information such as blood sugar, blood ketone, renal function, and electrolytes, but also can automatically analyze and process the data of physiological parameter information, thereby dynamically adjusting the treatment plan to achieve the function of intelligent data processing. If any monitoring index in the physiological parameter information monitored by the control host 600 exceeds the safe range, the control host 600 will automatically issue an alarm and notify the medical staff. At the same time, the control host 600 can trigger emergency treatment measures, such as automatically adjusting or suspending insulin infusion, to ensure that doctors can intervene in the patient's treatment in time and ensure the safety of the medical process.

[0045] In addition, the control host 600 of the present embodiment analyzes the drug response effect of the current patient based on the data of the monitored physiological parameter information and generates a personalized intelligent adjustment infusion mode for the current patient. During the analysis process, the control host 600 can calculate the metabolic law of the current patient according to the historical data and individual feedback of the patient by integrating machine learning algorithms, so as to provide a more personalized treatment plan. As time goes by, by continuously collecting the data of the patient's physiological parameter information and the individual feedback data after adjusting the injection amount accordingly, the machine learning algorithm in the control host 600 can be continuously supplemented and trained, so that the analysis ability of the control host 600 is continuously enhanced, and the insulin injection amount and injection speed are continuously optimized, thereby improving the treatment effect.

[0046] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, further, the indwelling assembly 100 of this embodiment further includes an indwelling needle body 110 and a steel needle 130. The indwelling needle body 110 is located outside the patient's body and is used for indwelling on the patient. The indwelling needle hose 120 is connected to one end of the indwelling needle body 110. For the convenience of structural description, the end facing the patient is defined as the distal end, and the end facing the operator is defined as the proximal end. The indwelling needle hose 120 is located at the distal end of the indwelling needle body 110. The steel needle 130 is detachably inserted into the indwelling needle hose 120 from the proximal end of the indwelling needle body 110. In a specific structure, there is a liquid inlet cavity 111 in the indwelling needle body 110. The proximal end of the liquid inlet cavity 111 communicates with the indwelling needle hose 120, and a plug 112 is provided at the distal end. The steel needle 130 is inserted into the plug 112 and enters the liquid inlet cavity 111 and then penetrates into the indwelling needle hose 120, protruding from the distal end of the indwelling needle hose 120. At this time, it is convenient to insert the protruding steel needle 130 into the patient's blood vessel, and then the indwelling needle hose 120 can be guided into the blood vessel. Then, the steel needle 130 is pulled out from the indwelling needle body 110, so that the steel needle 130 comes out of the indwelling needle hose 120, so that the indwelling needle hose 120 is retained in the blood vessel, and the indwelling needle body 110 can be fixed on the skin surface to keep the indwelling needle hose 120 stable in the blood vessel. After the steel needle 130 is pulled out from the plug 112, the plug 112 will self-seal the liquid inlet cavity 111 to realize the indwelling needle function.

[0047] As Figure 1 , Figure 3 shown, a connection joint 140 is provided on the side wall of the indwelling needle body 110. The connection joint 140 is communicated with the liquid inlet cavity 111. The connection joint 140 is used for docking with an infusion tube and is connected to the automatic injection part 700 through the infusion tube, so as to facilitate the injection of insulin.

[0048] As Figure 3 , Figure 4 , Figure 6 shown, further, the indwelling assembly 100 of this embodiment further includes an elastic member 200 and a pulling member 300. One end of the elastic member 200 is connected to the indwelling needle hose 120, and the other end is connected to the photoelectric sensor 500; the pulling member 300 is arranged on the indwelling needle body 110 and is connected to the elastic member 200; the elastic member 200 elongates by the release of the pulling member 300, so that the photoelectric sensor 500 pops out of the indwelling needle hose 120, or the elastic member 200 contracts by the drive of the pulling member 300, so that the photoelectric sensor 500 is received into the indwelling needle hose 120. By providing the pulling member 300 on the indwelling needle body 110 outside the patient's body, it is convenient to control the expansion and contraction of the elastic member 200, and then realize the functions of receiving and extending the photoelectric sensor 500. After the photoelectric sensor 500 is received into the indwelling needle hose 120, the photoelectric sensor 500 can be effectively protected to avoid damage to the photoelectric sensor.

[0049] As Figure 3 , Figure 4 , Figure 6 shown, further, the pulling member 300 of this embodiment specifically includes: an adjusting ring 310 and a pulling wire 320. The adjusting ring 310 is rotatably arranged on the indwelling needle body 110. One end of the pulling wire 320 is connected to the adjusting ring 310, and the other end is connected to one end of the elastic member 200 facing the photoreceptor 500. The pulling wire 320 is wound or unwound by the rotation of the adjusting ring 310, and can be wound on the adjusting ring 310 or on the indwelling needle body 110. When the pulling wire 320 is wound, the elastic member 200 is compressed, so that the photoreceptor 500 is received into the indwelling needle hose 120; when the pulling wire 320 is unwound, the elastic member 200 is released, so that the photoreceptor 500 pops out of the indwelling needle hose 120.

[0050] As Figure 3 , Figure 4 , Figure 5 , Figure 6 shown, in the specific structure, the adjusting ring 310 specifically includes a winding ring 311 and a screwing ring 312. The winding ring 311 and the screwing ring 312 are integrally formed. The winding ring 311 is located at the distal end of the screwing ring 312 and the outer diameter of the winding ring 311 is smaller than the outer diameter of the screwing ring 312. An installation step 113 is provided on the indwelling needle body 110. The winding ring 311 and the screwing ring 312 are sleeved on the indwelling needle body 110 and the proximal end abuts against the installation step 113, so that the outer wall of the screwing ring 312 can protrude from the side wall surface of the indwelling needle body 110, thus facilitating manual grasping and turning of the adjusting ring 310. External threads are provided at the distal end of the indwelling needle body 110, and a locking ring 150 is screwed thereon. By sleeving the locking ring 150 outside the winding ring 311, the entire adjusting ring 310 can be rotatably arranged on the indwelling needle body 110 and is not easily detached.

[0051] As Figure 6 , Figure 7 shown, further, a sealing ring 116 is provided at the connection between the pulling wire 320 and the indwelling needle body 110. In the specific structure, a groove 114 or a hole is provided on the inner wall of the indwelling needle body 110. The groove 114 or the hole extends to the distal end of the indwelling needle hose 120. A perforation 115 is provided on the indwelling needle body 110 and is communicated with the groove 114. Moreover, a hole is also provided on the winding ring 311, so that the pulling rope passes through the adjusting ring 310 and is connected to the adjusting ring 310 and then passes through the perforation 115 and enters the groove 114, and then extends to the distal end of the indwelling needle hose 120 to be connected to the elastic member 200. The sealing ring 116 is arranged in the perforation 115 to prevent blood leakage when the pulling wire 320 passes through the perforation 115.

[0052] As Figure 3 ,Figure 4 , Figure 6 As shown, in this embodiment, the stay wire 320 is specifically connected to the winding ring 311. A wire winding receiving groove 313 is provided on the winding ring 311. By turning the adjusting ring 310, the winding ring 311 is rotated. In this way, the stay wire 320 can be received in the wire winding receiving groove 313 during the winding process, making the winding process stable and the winding less likely to knot. When paying out the wire in the reverse direction, it is easier to unwind the stay wire 320. To make the force on the elastic member 200 more uniform, multiple stay wires 320 (for example, 2) can be provided, and the multiple stay wires 320 can be symmetrically arranged on the winding ring 311.

[0053] As Figure 6 , Figure 7 As shown, further, the indwelling assembly 100 of this embodiment further includes a backstop member 400. The backstop member 400 is provided on the indwelling needle body 110 and is matched with the adjusting ring 310. When the rotation of the adjusting ring 310 stops, the adjusting ring 310 does not rotate in the reverse direction due to the action of the backstop member 400. During the extension and retraction of the photoreceptor 500, since the photoreceptor 500 is subjected to the elastic force of the elastic member 200, the adjusting ring 310 is subjected to the force of the elastic member 200 during the rotation process and thus cannot be limited to a predetermined position. Therefore, by providing the backstop member 400 to limit the adjusting ring 310, the adjusting ring 310 can be maintained at the current position after the rotation stops. For example, when the photoreceptor 500 is completely retracted into the indwelling needle hose 120, the adjusting ring 310 is fixed at this position and does not move by the backstop member 400.

[0054] The structure of the backstop member 400 can be set in various forms, specifically as follows:

[0055] As Figure 6 As shown, in the first form, the backstop member 400 includes: a rubber ring 410 provided on the inner wall of the locking ring 150. The rubber ring 410 is in contact with the distal end of the winding ring 311, and there is a large frictional force between the rubber ring 410 and the distal surface of the winding ring 311. In particular, the wire winding receiving groove 313 on the winding ring 311 can be used to further increase the frictional force. This frictional force is greater than the elastic force of the elastic member 200 at the limit compression position. As long as the force applied to the turning ring 312 overcomes the frictional force, the adjusting ring 310 can be turned, and thus the telescopic adjustment function of the elastic member 200 can be realized. When the turning ring 312 is released, due to the relatively large frictional force, the elastic member 200 can be kept in the current state, realizing the backstop function.

[0056] As Figure 6As shown in the figure, in addition, the inner wall of the locking ring 150 is set as an inclined surface 411, so that the opening of the locking ring 150 forms a conical flare, and the rubber ring 410 is arranged on the inclined surface 411. Then, during the process of screwing the locking ring 150, the locking ring 150 gradually moves towards the adjusting ring 310. Due to the squeezing effect of the conical flare, the pressure can become greater and greater, so that the adjusting ring 310 can be completely locked. Especially after the photoreceptor 500 is completely retracted into the indwelling needle hose 120, the adjusting ring 310 needs to be locked through this process.

[0057] As Figure 7 shown, in the second form, a circle of internal teeth needs to be provided on the inner wall of the adjusting ring 310. The anti-back-off member 400 specifically includes: an anti-back-off block 420 and an anti-back-off elastic member 421. The anti-back-off block 420 is provided with anti-back-off teeth 422. The anti-back-off elastic member 421 is arranged in the indwelling needle body 110 and is connected to the anti-back-off block 420. The anti-back-off block 420 abuts against the inside of the adjusting ring 310 under the elastic force of the anti-back-off elastic member 421, so that the anti-back-off teeth 422 are stuck on the internal teeth. In the specific structure, by arranging an anti-back-off block 420 that can move radially in the indwelling needle body 110 and applying an elastic force to the anti-back-off block 420 through the anti-back-off elastic member 421, the anti-back-off block 420 can abut against the inner wall of the adjusting ring 310, so that the anti-back-off teeth 422 are stuck on the internal teeth. When the elastic force applied by the anti-back-off elastic member 421 is greater than the elastic force of the elastic member 200 at the limit compression position, after the finger releases the screwing ring 312, the elastic member 200 can be kept in the current state to achieve the anti-back-off function. As long as a large force is applied to the screwing ring 312, the anti-back-off teeth 422 can be squeezed through the internal teeth, so as to squeeze the anti-back-off block 420 away from the inner wall of the adjusting ring 310. In this way, the anti-back-off teeth 422 are separated from the internal teeth, and the adjusting ring 310 can be screwed, thereby realizing the telescopic adjustment function of the elastic member 200. In this way, the telescopic adjustment function of the photoreceptor 500 can be realized at any time by screwing the adjusting ring 310, and the photoreceptor 500 can be kept at the adjusted position without screwing.

[0058] As Figure 3 、 Figure 4 、 Figure 6As shown, further, the elastic member 200 of this embodiment specifically includes a support ring 210 and a spring 220. The photoreceptor 500 is disposed on the surface of the support ring 210. The pulling member 300 is connected to the support ring 210, and the spring 220 is connected to the support ring 210. The photoreceptor 500 is disposed on the surface of the support ring 210, so as to increase the contact area between the photoreceptor 500 and the blood, thereby improving the detection accuracy. The annular structure of the support ring 210 allows the steel needle 130 to pass through, without affecting the insertion of the indwelling assembly 100 into the blood vessel. Additionally, the photoreceptor 500 can also be configured as an annular shape to match the support ring 210, such that the photoreceptor 500 extends a relatively long distance axially and forms a relatively small cross-sectional area, facilitating accommodation within the indwelling needle hose 120 with a relatively small inner diameter.

[0059] Further, an anticoagulant and antibacterial coating is provided on the surface of the photoreceptor 500 and / or the indwelling needle hose 120 of this embodiment. The anticoagulant and antibacterial coating can avoid the risks of thrombosis and infection caused by the long-term indwelling of the indwelling needle hose 120. In a specific structure, a heparin coating and an antibacterial coating are adopted on the surfaces of the indwelling needle hose 120 and the photoreceptor 500. The heparin coating can effectively prevent thrombosis, while the antibacterial coating reduces the risk of infection.

[0060] In summary, an intelligent monitoring and treatment device for acute diabetic complications of the present application is used for the intelligent monitoring and treatment of acute diabetic complications such as hyperosmolar coma and diabetic ketoacidosis (DKA). The intelligent monitoring and treatment device combines a photoreceptor, a micropump, wireless transmission technology, a cloud platform, and a machine learning algorithm, aiming to achieve real-time monitoring of key indicators such as blood glucose, blood ketone, renal function, and electrolytes, and automatic treatment adjustment.
