Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology for medical equipment, and in particular to a dynamically positioned intelligent height adjustment system for medical drainage bags, which is suitable for precise management of various drainage scenarios after neurosurgery. Background Art

[0002] In the medical field, drainage bags are widely used, especially in neurosurgery clinical treatment. As the core medical device for maintaining intracranial pressure balance, the precise control of the hanging height of the drainage device is directly related to the incidence of postoperative complications and the quality of patient prognosis. Accurate adjustment of its height is crucial to drainage effect and patient safety. In the existing technology, the method of confirming the height of the drainage bag hook is relatively cumbersome and has many shortcomings. First, it is difficult to determine the zero point position of the drainage bag hook height. It needs to be determined manually with a spirit level. This process is not only time-consuming and labor-intensive, but also requires high skills of the operator. It is easily affected by the operator's business level and has large errors. In addition, according to clinical monitoring data, neurosurgery ICU patients have an average of 7.2 effective body position changes every 8 hours, and the traditional manual adjustment response delay is (28.5±6.7) seconds, which may cause abnormal drainage volume fluctuations of (4.6±1.1) mL, significantly increasing the risk of secondary cerebral hemorrhage;

[0003] Secondly, when measuring the height from the zero point, due to the influence of the verticality of the vertical support rod, there is a certain error in the adjusted height, and it is difficult to ensure the accuracy of the height. Furthermore, during the treatment process, patients often have changes in body position, bed head height, outpatient examinations, etc. This leads to the need to frequently readjust the height of the drainage bag, which increases the workload of medical staff. At the same time, it may also affect the drainage effect due to untimely adjustment or excessive or insufficient drainage volume, which is prone to poor drainage effect, impaired consciousness, intracranial infection, intracranial hypertension, epilepsy, and in severe cases, brain hernia and other adverse neurological sequelae and death. In summary, the existing drainage bag height adjustment method has major defects in terms of ease of operation, practicality and positioning accuracy. The development of a new height adjustment system with autonomous perception, intelligent decision-making and dynamic compensation capabilities has become an urgent need in the field of neurosurgical instruments. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a dynamically positioned medical drainage bag height intelligent adjustment system.

The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1-2As shown, the present invention provides a dynamically positioned medical drainage bag height intelligent adjustment system, comprising a height adjustment bracket 1, a drainage bag hook 2, a detection device 3, a control box 4 and a PLC controller 5. The height adjustment bracket 1 comprises a first servo guide rod 11 and a second servo guide rod 12; the first servo guide rod 11 and the second servo guide rod 12 are both mounted on the top of the control box 4, the first servo guide rod 11 and the second servo guide rod 12 both use a screw slide, the first servo guide rod 11 and the second servo guide rod 12 face opposite directions, and the drainage bag hook is mounted on the slide of the first servo guide rod 11 2. The detection device 3 is mounted on the slide of the second servo guide rod 12. The PLC controller 5 is disposed within the control box 4 and includes a zero position detection module 51 and a height adjustment module 52. The zero position detection module 51 is used to control the second servo guide rod 12 and the detection device 3 to determine a zero position parallel to the patient's forehead or lateral ventricle, and the height adjustment module 52 is used to control the first servo guide rod 11 to automatically adjust the height of the drainage bag hook 2 based on the zero position. The first servo guide rod 11 and the second servo guide rod 12 are both driven by servo motors. The controller 5 is primarily composed of host computer software developed by a PLC and a PC. The controller 5 includes a code scanning input module for inputting patient and medical information, which is used to enter patient and medical staff information.

Automatic dynamic adjustment of the drainage bag height is achieved through the host computer software developed by the PLC and PC in the controller 5.

[0024] A drainage tube fixing device 21 is provided on one side of the drainage bag hook 2. The drainage tube fixing device 21 is provided with a slot hole for fixing the position of the drainage tube. The drainage tube passes through the slot hole and is then connected to the drainage bag, thereby fixing the drainage tube of the drainage bag and preventing the drainage bag from being weighed incorrectly due to the dragging of the drainage tube.

[0025] Furthermore, an interactive device is provided on one side of the height adjustment bracket 1, and the detection device 3 includes a laser area scanning sensor 31 and a laser generator 32, and the laser area scanning sensor 31 and the laser generator 32 are both installed on the slide of the second servo guide rod 12;

[0026] The zero position detection module 51 includes an automatic detection unit 511 and a manual adjustment unit 512. The automatic detection unit 511 controls the second servo guide rod 12 to drive the laser area scanning sensor 31 to the highest height within a predetermined detection area height range, and then slowly moves downward to scan. When the patient's forehead is detected, the second servo guide rod 12 stops moving and records the height at that time as the zero position. The system automatically sets the zero position, which can also be manually modified through the interactive device. The automatic detection unit 511 can automatically confirm the zero position at a set time interval to ensure that the system can automatically adjust the height of the drainage bag as the patient's body moves or the headboard height changes. The manual adjustment unit 512 is used to control the second servo guide rod 12 and start the laser generator 32. By controlling the second servo guide rod 12, the laser generator 32 is driven to rise and fall. When the laser spot emitted by the laser generator 32 is aligned with the patient's forehead or parallel to the lateral ventricle, the user can set the height at that time as the zero position through the interactive device.

[0027] Furthermore, the PLC controller 5 includes a height correction module 53, which is configured to correct the actual height of the drainage bag hook 2 on the first servo guide rod 11 according to preset position correction parameters, ensuring that the drainage bag drainage fluid outlet is at the desired actual height relative to the patient's forehead or lateral ventricle. The position correction parameters can be set within the interactive device's interface to ensure that when the drainage bag is hung on the drainage bag hook 2, the drainage bag drainage fluid outlet is aligned at a predetermined height above the zero point. The position correction parameters only need to be set upon initial use; subsequent use of the same size drainage bag will use these position correction parameters by default.

[0028] Furthermore, the PLC controller 5 is also provided with a flow monitoring module 54 and an alarm module 55; the flow monitoring module 54 includes a weighing unit 541 and a flow conversion unit 542, the weighing unit 541 obtains the weight measured by the weighing sensor 6 installed at the connection of the drainage bag hook 2, and the flow conversion unit 542 converts the cumulative flow value according to the current weight, and converts it into an instantaneous flow value according to the instantaneous weight change; the input end of the alarm module 55 is connected to the output end of the flow monitoring module 54, when the measured instantaneous flow value, cumulative flow value or drainage time exceeds the preset warning threshold, the alarm module 55 controls the alarm device 7 to start and issue an alarm; the alarm device 7 is electrically connected to the PLC controller 5, and the alarm device 7 includes an audible and visual alarm, which is provided at the control box 4.

[0029] Furthermore, it also includes an intracranial pressure data access module 56, and the control box 4 is provided with a data interface for data interaction with the intracranial pressure monitor 8; the intracranial pressure data access module 56 obtains the invasive intracranial pressure value of the intracranial pressure monitor 8 through the data interface, and the output end of the intracranial pressure data access module 56 is connected to the input end of the alarm module 55, and the PLC controller 5 automatically adjusts the height of the drainage bag hook 2 according to the invasive intracranial pressure value, and controls the alarm device 7 to start emitting an audible and visual alarm prompt; when the invasive intracranial pressure value is higher than the intracranial pressure warning threshold, the drainage bag hook 2 is controlled to lower a preset distance, and the intracranial pressure warning threshold and the lowered preset distance can be set through the PC operation interface.

[0030] Furthermore, a universal wheel 41 is provided at the bottom of the control box 4. The universal wheel 41 is height-adjustable and lockable, which facilitates the movement of the system and the adjustment of the parallelism of the base.

[0031] A plurality of levels 42 are installed on the top of the control box 4 to detect whether the system device is level and to assist in adjusting the levelness of the device to ensure that the first servo guide rod 11 and the second servo guide rod 12 are in a vertical state.

[0032] Furthermore, the universal wheel 41 is installed at the bottom of the control box 4 through a threaded telescopic rod, and the spirit level 42 and the threaded telescopic rod are electrically connected to the PLC controller 5. The PLC controller 5 is provided with an automatic leveling module 57, which adjusts each threaded telescopic rod according to the data feedback from each spirit level 42 to keep the control box 4 level.

[0033] Furthermore, the interactive device includes a foldable microcomputer 9 electrically connected to the PLC controller 5. The foldable microcomputer 9 can be folded and adjusted to move up and down, and the height can be adjusted according to user needs. It is used to operate and cooperate with the PLC controller 5 to control the system. It can be used for operations such as entering and saving patient information, medical staff login operations, setting system parameters, recording and saving real-time data, and querying historical data.

[0034] Furthermore, the system has a hierarchical authority management function. Only personnel with different levels of authority can log in to the system to perform corresponding parameter settings, zero point position confirmation, weight tare confirmation and other operations.

[0035] Furthermore, the PLC controller 5 is also provided with a data storage and analysis module 58, which is used to save the instantaneous flow value or cumulative flow value of the drainage fluid at set time intervals, analyze data such as the maximum drainage flow value, cumulative drainage flow value, operating time, etc., and has data export and tracing functions.

[0036] The operating process of the dynamic positioning medical drainage bag height intelligent adjustment system of the present invention is as follows: the medical staff logs into the system by scanning the employee ID barcode or manually entering the employee ID, scans the ID barcode on the patient's wristband, queries the patient's relevant information, and confirms the drainage type; after confirming that the relevant system parameters are correct and that the patient is lying flat and ready, they click the corresponding zero point position button according to the drainage type, and the system automatically performs the zero point position operation:

[0037] When the patient needs to undergo ventricular drainage or subdural drainage, the zero point position is on the forehead. The automatic detection mode can be used to determine the zero point position. The operator presses the automatic detection button of the interactive device to start the second servo guide rod 12. The second servo guide rod 12 drives the slide to descend until the laser area scanning sensor 31 scans the patient's forehead and automatically stops. The slide height of the second servo guide rod 12 at this time is fed back, and the first servo guide rod 11 adjusts the slide to the same height. At this time, the zero point position change can be continuously monitored and the drainage bag height can be automatically adjusted.

[0038] When the patient needs epidural drainage, subcutaneous drainage, hematoma cavity drainage, or tumor cavity drainage, the zero point position is aligned with the patient's external auditory canal. When used for the first time, the operator needs to use the manual adjustment mode to confirm the zero point position. The operator presses the manual adjustment button of the interactive device to start the second servo guide rod 12. The second servo guide rod 12 drives the slide to descend until the light spot of the laser generator 32 is aligned with the patient's external auditory canal. At this time, the laser area scanning sensor 31 records the height of the patient's forehead entering the scanning area and reaches h2, and feeds back the slide height of the second servo guide rod 12 at this time. The first servo guide rod 11 adjusts the slide to the same height; at this time, the zero point position change can be continuously monitored and the drainage bag height can be automatically adjusted.

[0039] The patient's forehead is detected when the portion of the laser area scanning sensor 31's scanning area that enters it reaches a height H. In automatic detection mode, H uses the default value h1; in manual adjustment mode, H uses the measured value h2. After completing the zero point operation, click the corresponding working position button, and the system automatically monitors and adjusts the drainage bag hook height.

[0040] The beneficial effects of the dynamic positioning medical drainage bag height intelligent adjustment system of the present invention are: convenient and efficient operation, medical staff only need to complete identity login by scanning the code or manual input, scan the patient's wristband to obtain information and confirm the drainage type, and trigger the zero point positioning and height adjustment function with one button, without the need for tedious manual measurement and repeated adjustment of the drainage bag height, greatly simplifying the operation process and significantly improving work efficiency; accurate and reliable positioning, adopting the PLC controller and the upper computer software developed by the foldable microcomputer to collaboratively control the high-precision servo guide rod system, combined with the dual positioning technology of the laser area scanning sensor and the laser generator, to achieve a drainage bag height adjustment accuracy of more than 0.1 mm, accurately ensuring the height matching of the drainage bag drainage fluid outlet position with the patient's forehead or lateral ventricle and other key positions, ensuring the accuracy and safety of drainage treatment; rapid dynamic response, and real-time monitoring of the detection device By measuring the zero-point position offset caused by factors such as changes in patient position and bedside height, the system can respond quickly and automatically adjust the drainage bag height in a short time, effectively avoiding the risk of poor drainage or backflow due to height error, and providing patients with continuous and stable treatment support; the system integrates flow monitoring, intracranial pressure data access, automatic alarm and other functions, uses weighing sensors to convert drainage fluid flow in real time, and intelligently adjusts the drainage height based on intracranial pressure monitoring data, and triggers sound and light alarms in time in case of abnormal situations; it also has functions such as automatic leveling, data storage and analysis, and hierarchical authority management, which fully meet clinical treatment and data management needs; automated operation greatly reduces the workload of medical staff in the process of drainage bag adjustment and monitoring, reduces the risk of manual operation errors, and enables them to devote more energy to patient condition observation and nursing work, optimizes the use of medical resources, and improves the overall quality of care.
