Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an intelligent pressure bandage. Background Technology
[0002] Spinal surgery is an important means of treating spinal diseases, including spinal correction, spinal fusion, and lumbar disc surgery. The postoperative recovery period is crucial to the patient's long-term health and the surgical outcome.
[0003] Following spinal surgery, patients often need to wear immobilization belts or braces to restrict spinal movement, provide stability, reduce postoperative bleeding and swelling, and promote wound healing. However, traditional immobilization belts or braces have many limitations, such as the inability to precisely control pressure, the lack of real-time monitoring and adjustment capabilities, and the inability to provide personalized treatment plans based on the patient's recovery progress.
[0004] Most existing pressure bandages are non-intelligent, relying primarily on manual adjustment by medical staff. This lack of precise pressure control and the inability to monitor the patient's recovery status in real time further hinders the timely acquisition of patient information and adjustments to treatment plans due to the absence of intelligent monitoring and adjustment mechanisms.
[0005] Existing pressure bandages suffer from the following main problems: First, some traditional bandages rely on manual adjustment, making it difficult to achieve precise and consistent pressure control, and further limiting the range of pressure adjustment, thus affecting the consistency of treatment effects; second, the lack of real-time monitoring of bandage pressure and the patient's physiological state prevents medical staff from obtaining timely information on the patient's recovery; third, they cannot be integrated with remote medical monitoring systems, limiting the timeliness and convenience of medical services; and fourth, the pressure concentration at a single point due to the inflation of a single pressure bladder may cause patient discomfort, affecting treatment compliance and recovery quality. Therefore, current technology has not yet provided a pressure bandage that integrates self-distributed pressure adjustment, real-time monitoring, and remote monitoring. Utility Model Content
[0006] To address the above problems, this utility model proposes an intelligent pressure bandage, the specific technical solution of which is as follows:

[0013] Furthermore, the sensor module includes a pressure sensor and a wound sensor. The pressure sensors are arranged in an array around the airbag, and the wound sensor is located at the center of the airbag.
[0014] Furthermore, the wound sensor is a pH sensor.
[0015] Furthermore, the bandage body is provided with an encapsulation layer for covering each airbag.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0031] like Figures 1 to 4 As shown, a smart pressure bandage includes a bandage body 1, a sensor module 2, medical gauze 3, and a control module 4; wherein:
[0032] The bandage body 1 has multiple independent airbags 11 arranged in an array inside. Inflating and deflating the airbags 11 can control the pressure applied to the waist by the airbags 11.
[0033] The sensor module 2 is mounted on the airbag 11 to detect the pressure of each airbag 11 and the wound condition, so as to monitor the patient's physiological parameters in real time.
[0034] The medical gauze 3 is detachably mounted on the bandage body 1 for application to the patient's wound.
[0035] The control module 4 is communicatively connected to the sensor module 2, and is used to receive the data detected by the sensor module 2, control the pressure of the corresponding airbag 11, and transmit the data to the terminal.
[0036] In one embodiment, the two ends of the bandage body 1 are respectively provided with connectable straps 5, and the ends of the two straps 5 are provided with waist belt buckles for use, so that the two straps 5 can be fastened quickly and adapt to different waist sizes of patients, thereby fixing the bandage body 1 to the patient's waist.
[0037] like Figure 2 , 3 As shown, the sensor module 2 includes a pressure sensor 21 and a wound sensor. The pressure sensors 21 are arranged in an array around the airbag 11, and the wound sensor is located at the center of the airbag 11.
[0038] Because multiple airbags 11 are independently distributed, they form a distributed pressure when inflated, which can apply localized pressure to the wound, promoting wound healing and avoiding pressure concentration or uneven pressure during inflation. The pressure sensor 21 on each airbag 11 detects the pressure distribution from different locations, facilitating the monitoring of the pressure distribution within the airbags and enabling coordinated pressurization using adjacent airbags 11.
[0039] The wound sensor detects the amount of tissue fluid seepage from the wound to determine the healing status of the spinal surgery wound. When a wound sensor detects wound data, the corresponding airbag 11 is pressurized to compress the wound and prevent excessive seepage of tissue fluid.
[0040] Preferably, the wound sensor is a pH sensor 22, or other sensor capable of detecting wound physiological data.
[0041] The pH data detected by the pH sensor 22 can be used to indicate the wound healing process and infection risk. Normal skin typically has a pH between 4.0 and 6.0, but the pH varies depending on the type of wound. For example, acute wounds have a pH close to neutral or slightly alkaline; chronic wounds usually have a more alkaline pH, between 7.0 and 9.0; and infected wounds may have a higher pH, reaching 8.0 to 9.0 or higher. Low pH helps inhibit bacterial growth and promotes collagen synthesis by fibroblasts, thereby accelerating wound healing; high pH promotes bacterial growth and slows down the wound healing process.
[0042] Therefore, when the pH sensor 22 detects pH data within the wound area, it can pinpoint the specific location of the wound and initiate a pressurization program on the corresponding airbag 11. The pressurization level of the airbag 11 is then controlled according to different pH ranges, thereby applying varying degrees of pressure to the wound to promote healing. Simultaneously, the detected pH value provides medical personnel with intuitive pH data to assess wound healing progress, facilitating subsequent treatment effectiveness evaluation and optimization of treatment plans.
[0043] Furthermore, when there is excessive wound exudate, the pH sensors 22 on adjacent or multiple airbags 11 can detect pH data within the wound area, thereby enabling multiple airbags 11 to simultaneously initiate the pressurization process to reduce tissue fluid exudation. When the pH data is outside the wound area, the airbag 11 corresponding to the pH sensor 22 only performs pre-pressurization.
[0044] like Figure 1 As shown, the bandage body 1 is provided with an encapsulation layer 12 for covering each airbag 11; the encapsulation layer 12 is used to encapsulate and protect the pressure sensor 21 and pH sensor 22 without affecting the corresponding detection of each sensor. For example, the encapsulation layer 12 is multiple layers of ordinary gauze, or other flexible materials that facilitate tissue fluid penetration; and the encapsulation layer 12 can be pressed tightly onto the airbag 11 with a wide-mouth cap 13, facilitating the removal of the ordinary gauze.
[0045] Preferably, the medical gauze 3 is bonded to the encapsulation layer 12 by Velcro; Velcro can be attached to the wide-mouth cap 13, so that the medical gauze 3 can be quickly disassembled and replaced.
[0046] In another embodiment, the control module 4 is encapsulated within an openable control box 6, which is mounted on a strap 5.
[0047] like Figure 4As shown, the control module 4 includes a microcontroller 41 and a micro air pump 42 and a control valve 43 electrically connected to it. Each airbag 11 is connected to an air tube 44 equipped with a control valve 43. The air tubes 44 are all connected to the micro air pump 42. The microcontroller 41 is used to control the start and stop of the micro air pump 42 and the opening and closing of the control valve 43, thereby controlling the inflation and deflation of each airbag 11 individually through the control valve 43, and realizing the control and adjustment of the airbag 11 pressure.
[0048] The microcontroller 41 is electrically connected to the pressure sensor 21 and the pH sensor 22 via wire 23 or wirelessly connected to them, thereby receiving pressure data and pH value data. Based on this data, the microcontroller 41 controls the control valve 43 on the air tube 44 of the corresponding airbag 11 to open, and then starts the micro air pump 42 to regulate the pressure of the airbag 11.
[0049] The microcontroller 41 can preset high and low pressure thresholds or pH ranges. After comparing the data detected by the pressure sensor 21 and pH sensor 22 with the preset values, the microcontroller 41, control valve 43, and air pump perform corresponding linkage processing. When the airbag 11 is worn, its pressure is pre-inflated to the low pressure threshold. When a pH value within the wound range is detected, the corresponding airbag 11 pressure is inflated to the high threshold, thereby achieving automatic pressure adjustment and control at the wound site. The pH range can be linearly correlated with the airbag 11 pressure, thus applying matching pressure to different wounds.
[0050] like Figure 4 As shown, the control module 4 also includes a wireless communication module 45, which is electrically connected to the microcontroller 41 and communicates with the terminal to transmit the detected data to the terminal. For example, the terminal can be a medical system or a device with a display function; furthermore, the terminal can also have an alarm function for fault alarms of the sensor module 2 and the control module 4, as well as pH value abnormality alarms.
[0051] In one embodiment, the control box 6 is provided with a battery 61 for powering the control module 4. Furthermore, the microcontroller 41 may also integrate an LED display 62 for displaying pressure data, pH value, and battery 61 power level, as well as a button 63 for turning on the battery 61.
[0052] In use, the bandage body 1 is secured to the wound location on the patient's waist using the straps 5. Pressing button 63 connects the power supply. The microcontroller 41 controls the control valve 43 and the micro air pump 42 to pre-inflate the airbag 11, ensuring the initial pressure inside the airbag 11 reaches the low threshold preset by the microcontroller 41. When the pH sensor 22 detects pH data within the wound area, the corresponding control valve 43 of the airbag 11 opens, controlling the micro air pump 42 to inflate the airbag 11, causing the pressure to reach the high threshold, thus compacting the wound, preventing excessive tissue fluid leakage, and promoting wound healing. The pressure level of the airbag 11 can also be controlled according to different pH ranges. Simultaneously, the microcontroller 41 displays the detected pressure and pH data on the display screen 62 and transmits the data to a terminal, enabling medical personnel to monitor the patient's recovery in real time, adjust treatment plans promptly, and improve treatment efficiency.
