Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a synchronous mobile infusion device for early postoperative walking exercises. Background Technology

[0002] The current status of laparoscopic surgery in my country is 156,820 laparoscopic procedures per year. There is a type of disease in China that requires nearly 1.5 million inguinal hernia surgeries every year. Considering that the treatment of adult inguinal hernias mainly relies on surgery, and given the large number of patients in China, the number of surgeries is enormous. The time for postoperative flatus after abdominal surgery varies from patient to patient and from condition to condition.

[0003] Because blood is prone to clotting and forming thrombi after abdominal, gynecological, or thoracic surgeries, thrombi can cause local circulatory disorders. If an embolus breaks off and causes a pulmonary embolism, the patient will be in danger. Therefore, doctors generally advise patients to get out of bed and move around as soon as possible after surgery. Early ambulation helps relieve muscle pressure on veins, promotes venous return, and reduces the chance of venous thrombosis. However, since patients need intravenous infusions after surgery, a caregiver is needed to help them carry the IV bottle / bag. However, manually carrying the IV bottle / bag requires holding it high up, which can cause arm pain over time. An IV stand can also be used, but it requires manual pushing and is extremely inconvenient to use. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0026] Please see Figures 1-10 In this embodiment of the present invention, a synchronously moving infusion device for early postoperative walking exercises includes a control box 1. A synchronously moving component is located below the control box 1, enabling synchronous movement of the device when the patient moves postoperatively. A control box 2 3 is fixedly mounted at the top of the control box 1, and a mounting plate is fixedly mounted at the bottom of the control box 2 3. The mounting plate is connected to the top of the control box 1 via mounting bolts. An adjusting screw 303 is rotatably mounted in the middle of the control box 2 3. A support column 4 is fixedly mounted at the top of the control box 2 3, and a hollow adjusting column 401 slides inside the support column 4. The bottom of the adjusting column 401... The unit is fixedly provided with a connecting seat 402 that is threadedly connected to the adjusting screw 303. When the adjusting screw 303 rotates, it drives the adjusting column 401 to move. The inner side of the support column 4 is provided with a sliding groove. The bottom end of the adjusting column 401 is fixedly provided with a slider that slides in cooperation with the sliding groove, which guides the movement of the adjusting column 401. The surface of the support column 4 is slidably provided with an adjusting seat 403. A support plate 408 is rotatably provided on one side of the adjusting seat 403. The top end of the adjusting column 401 is fixedly provided with a placement box 5 for placing drip bottles / bags. The top end of the adjusting column 401 is fixedly provided with a mounting plate, which is connected through the bottom end of the placement box 5.

[0027] Preferably, the lifting mechanism of the adjusting column 401 adopts closed-loop servo control: the drive motor 302 is a 57 stepper motor, directly connected to the adjusting screw 303 via a coupling, with a step angle accuracy of 0.9°; the connecting seat 402 has an embedded absolute encoder, which provides real-time feedback on the height position of the adjusting column 401, and dynamically compensates for lifting errors after comparing it with the preset value of the single-chip microcomputer using a PID algorithm. The support column 4 is equipped with dual redundant limit switches. When the adjusting column 401 moves to the upper limit of 1.8m or the lower limit of 0.6m, the power to the drive motor 302 is immediately cut off and the screw is locked. Patients can select a preset height level via a handheld remote control, or achieve personalized height adaptation via the ±5cm fine-tuning key. The system is equipped with an overload protection module, which automatically triggers emergency braking when the screw bears a pressure exceeding 500N.

[0028] In this embodiment, preferably, the synchronous moving component includes a base plate 2, two steering shafts 201, and two mounting seats 209. The base plate 2 is fixedly disposed at the bottom of the control box 1, and a mounting plate is fixedly disposed at the bottom of the control box 1.

Two moving wheels 2011 are fixedly disposed on the surface of the axle 2010. The movement of the device is realized by the cooperation between the moving wheels 2011 and the steering wheels 202, so that it can follow the patient's movement.

[0029] In this embodiment, preferably, a synchronous pulley 203 is fixedly provided on the surface of the steering shaft 201, and a synchronous belt 204 is driven between the two synchronous pulleys 203.

Under the meshing of the transmission gear 4 2018 and the transmission gear 3 2015, the mounting shaft 2013 is driven to rotate. Under the meshing of the bevel gear 2 2014 and the bevel gear 1 2012, the axle 2010 is driven to rotate, thereby driving the moving wheel 2011 to rotate, realizing the synchronous movement of the device. The top of the base plate 2 is equipped with a lithium battery 2019 to provide power.

[0031] Preferably, the control box 1 integrates an STM32 series microcontroller control system, and an infrared sensor array and a pressure sensing module are added to the synchronous moving parts. The infrared sensor array is distributed on the front side of the base plate 2 to detect the patient's walking direction and distance in real time, and eliminates environmental interference through a signal filtering algorithm; the pressure sensing module is embedded in the surface of the support plate 408 to monitor the weight-bearing status of the patient's arm. After receiving the sensor data, the microcontroller dynamically adjusts the speed and direction of the drive motor 207 and the drive motor 2017: when the infrared sensor detects that the patient's movement direction deviates beyond a set threshold, the drive motor 207 corrects the angle of the steering wheel 202 through the transmission gear 208 and the steering shaft 201; when the pressure sensing module detects that the load on the support plate 408 exceeds a safe value, it triggers an audible and visual alarm and suspends the driving of the moving wheel 2011 to prevent the equipment from tipping over.

The drive shaft of the drive motor 302 is connected to the bottom end of the adjusting screw 1 303. The rotation of the drive shaft of the drive motor 302 can drive the adjusting screw 1 303 to rotate, thereby realizing the automatic adjustment of the position of the adjusting column 401.

[0033] It should be noted that drive motor 1 207, drive motor 2 2017, and drive motor 3 302 are all motors equipped with reducers and can rotate in both directions. Furthermore, drive motor 1 207, drive motor 2 2017, and drive motor 3 302 are all controlled by an external remote control, which is placed in the patient's hand for self-control.

[0034] In this embodiment, preferably, a fixed seat 404 is fixedly provided on the side of the support column 4, and an adjusting screw 405 is rotatably provided between the two fixed seats 404 and threadedly connected to the other side of the adjusting seat 403. When the adjusting screw 405 rotates, the position of the adjusting seat 403 can be adjusted, thereby adjusting the position of the support plate 408. A turntable 406 is fixedly provided at the bottom end of the adjusting screw 405, and the turntable 406 can drive the adjusting screw 405 to rotate conveniently.

[0035] In this embodiment, preferably, the end of the support plate 408 near the support column 4 is provided with a rotating groove 409 that rotates with one side of the adjusting seat 403. A locking screw 407 is fixedly provided on one side of the adjusting seat 403. The surface of the rotating groove 409 is provided with a rotating hole corresponding to the locking screw 407, and a locking nut is threaded on the end of the locking screw 407.

[0036] In this embodiment, preferably, the interior of the placement box 5 is divided into multiple placement cavities 502 by a partition 501, which can hold the drip bottle / bag. The bottom of the placement box 5 is provided with a through hole 503 communicating with the placement cavity 502, so that the bottle mouth of the drip bottle / bag passes through and is placed outside. The side of the partition 501 is provided with a hook for hanging the drip bottle / bag. The top of the placement box 5 is hinged to a cover plate 504. The surface of the cover plate 504 is provided with an air inlet 505. An installation cylinder 507 is fixedly provided on the surface of the air inlet 505. An exhaust fan 508 is provided inside the installation cylinder 507, so that outside air can be blown into the interior of the placement box 5. A protective net 509 is embedded at the top of the installation cylinder 507 to protect the internal exhaust fan 508. A heating plate 506 is provided on the inner side of the cover plate 504, which can heat the drip bottle / bag in the placement cavity 502.

[0037] In use, first open the cover 504, place the IV bottle / bag into the placement cavity 502 of the placement box 5, and ensure that the dispensing end of the IV bottle / bag passes through the through hole 503 to the outside. When the temperature is low, turn on the heating plate 506 and the exhaust fan 508. The exhaust fan 508 blows hot air into the placement cavity 502 to heat the IV bottle / bag inside. At the same time, the turntable 406 drives the adjusting screw 405 to rotate. When the adjusting screw 405 rotates, the position of the adjusting seat 403 can be adjusted, thereby adjusting the position of the support plate 408. The patient's hand is placed on the support plate 408 for arm support. At the same time, the elastic limiting band 4010 can limit the patient's hand to prevent it from falling off. Then, start the drive motor 302. The drive motor 302 drives the adjusting screw 303 to rotate, thereby adjusting the position of the adjusting column 401 inside the support column 4, adjusting the height of the placement box 5. The degree is adjusted; simultaneously, drive motor 2017 is controlled, and the drive shaft of drive motor 2017 drives drive gear 4 2018 to rotate.

Under the meshing of bevel gear 2 2014 and bevel gear 1 2012, the axle 2010 is rotated, thereby driving the moving wheel 2011 to rotate, realizing synchronous movement of the device. When turning is required, drive motor 1 207 is started, and the drive shaft of drive motor 1 207 drives drive gear 2 208 to rotate. Under the meshing of drive gear 2 208 and drive gear 1 205, one of the steering shafts 201 is rotated. Under the transmission cooperation of synchronous pulley 203 and synchronous belt 204, the other steering shaft 201 is rotated synchronously, thereby adjusting the movement direction of the two steering wheels 202, realizing synchronous movement of the device following the patient.

[0038] Preferably, the temperature control system of the placement box 5 adopts a closed-loop control strategy: a PT100 high-precision temperature sensor is embedded in the inner side of the partition 501 to collect the temperature of the medicine solution in each placement cavity 502 in real time; the surface of the heating plate 506 is covered with a thermally conductive silicone layer, and the temperature is precisely controlled from 10-45℃ through a PWM voltage regulation module; the exhaust fan 508 and the heating plate 506 are controlled by a single-chip microcomputer. When the temperature sensor detects that the local temperature exceeds the set value ±2℃, the exhaust fan 508 is activated for forced convection heat dissipation, while reducing the heating power. The inner side of the cover plate 504 is provided with a double-layer heat insulation structure, with the outer layer being a transparent polycarbonate protective cover and the inner layer filled with aerogel insulation material to ensure that the heat is concentrated on the medicine solution area. The system has a preset low-temperature infusion protection mode, which automatically activates the constant temperature maintenance function when the ambient temperature is below 15℃ to avoid medicine crystallization or patient discomfort.
