Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a lumbar surgery incision protection device for orthopedics. BACKGROUND

[0002] More and more office workers have brought great pressure to the lumbar vertebrae due to long-term office work, long-term sitting or professional habits, resulting in frequent lumbar disc herniation and other lumbar problems. Lumbar disease is a group of diseases mainly manifested as low back pain and limited lumbar movement. It has multiple types and different severity. Mild lumbar muscle strain can be recovered by rest and physiotherapy, while severe lumbar spondylolisthesis may require surgical treatment. Lumbar disc herniation can compress the nerve, causing radiating pain in the lower extremities, nerve root and cauda equina nerve injury and other symptoms. In severe cases, it may even cause sphincter and sexual dysfunction, muscle atrophy and paralysis, sensory loss and other problems. At this time, the open surgery of the lumbar vertebrae in the orthopedics department is the most effective solution.

[0003] During the open surgery of the lumbar vertebrae in the orthopedics department, a surgical incision about ten centimeters long is usually made at the protruding position (the back of the waist) of the patient. Then gradually expose the intervertebral disc, remove the locally protruding intervertebral disc, and reduce the compression on the nerve root. According to the local situation, if it is accompanied by spinal instability, bone grafting and internal fixation for fusion treatment need to be considered. After local fixation, the incision is washed and a drainage tube is placed, and then the incision is closed layer by layer.

[0004] Based on the purpose of protecting the incision position of the lumbar spine after operation, the prior art provides means including surgical incision film, protection of drainage tube, and irrigation of the wound in the early stage of infection. The Chinese patent with publication number CN214912405U discloses a protection device for lumbar intervertebral foramen mirror surgical incision, which includes: a flow guide part for placing on both sides of the surgical incision, the flow guide part is made of flexible material, the number of flow guide parts is two, and the two flow guide parts cooperate to form a flow guide channel; a liquid collecting bag, the liquid collecting bag has an opening, and the opening is located below the flow guide channel; a suction bottle provided with a suction tube and a bottle body, one end of the suction tube penetrates into the interior of the liquid collecting bag through the opening, and the other end of the suction tube penetrates into the interior of the bottle body through the bottle body. The Chinese patent with publication number CN216022428U discloses a single-tube flushing device for treating early-stage infection of a lumbar postoperative incision, which includes a transparent empty tube, a connecting head is arranged at the bottom of the empty tube, a soft tube is detachably connected to the bottom of the connecting head, a spray head is arranged at the bottom of the soft tube, a piston is arranged in the interior of the empty tube, a connecting handle is arranged at the top of the piston, a plate body is arranged at the top of the empty tube, a support is arranged at the top of the plate body, a control block is arranged on the support, a micro motor and a battery electrically connected are arranged in the control block, a switch and a charging port are arranged on the control block, a rotating shaft of the micro motor is connected with a lead screw, the lead screw penetrates out of the control block and is threadedly connected with the connecting handle through the plate body, a limiting rod is arranged at the bottom of the plate body, and the limiting rod is slidably connected with the connecting handle. The Chinese patent with publication number CN105266899B provides a disposable wet negative pressure suction incision protection sleeve, which includes a plastic shape extension protection film channel, one end of the plastic shape extension protection film channel is obliquely provided with an elastic circular ring, the other end of the plastic shape extension protection film channel is provided with an elastic double ring, a hollow water delivery pipe is arranged on the elastic circular ring, a fixed negative pressure pipe is arranged on one side of the plastic shape extension protection film channel, and a deformable protection film channel is arranged on the other side of the plastic shape extension protection film channel.

[0005] After orthopedic lumbar posterior open surgery, a drainage tube usually needs to be indwelled for 4-10 days, and the patient can only get out of bed to defecate after the drainage tube is removed. During this period, especially female patients without indwelling urinary catheter, can only use a bedpan to lie down on the bed to defecate, and such defecation method is easy to cause urine backflow to contaminate the lumbosacral incision. At this time, if the patrol nurse cannot timely find and replace the contaminated and wet incision dressing, it is easy to cause incision infection, affect incision recovery, and even cause surgical failure. In addition, the body pressure on the lumbar incision during lying down and the sweat wetting the incision dressing will affect the healing of the incision and increase the risk of surgical site infection.

[0006] Compared to monitoring the moisture of the lumbosacral incision and changing dressings promptly, existing technologies primarily employ drainage and collection methods to drain contaminants (urine or other bodily fluids) flowing near the incision to other collection areas. However, this approach heavily relies on the precision of the device's design and the patient's ability to remain calm and avoid external factors such as twisting the device. When the device is twisted by the patient (in pain or other situations requiring slight movement), the drainage effect is minimal, allowing contaminants to still flow to the incision site. Furthermore, the device's design may prevent contaminants from being detected by medical staff in a timely manner. Therefore, patients require a protective device to monitor their surgical incision site in real time and provide timely feedback on any abnormalities. Based on this, the present invention provides a protective device for orthopedic lumbar spine surgical incisions.

[0007] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0008] Postoperative wound healing is actually a special inflammatory process of tissue repair, namely the process of scar formation, proliferation, contraction, and maturation. It is generally divided into three stages: exudation, proliferation, and contraction or maturation. During the wound healing process, poor local blood circulation, insufficient plasma protein content, and vitamin deficiency can all affect wound healing.

[0009] Following open posterior lumbar spine surgery in orthopedics, the surgical incision is typically located in the patient's lumbar region. When the patient is lying flat, the incision is subjected to pressure from the body and the bed. Furthermore, to reduce the risk of urinary tract infections (UTIs), indwelling catheters need to be removed as soon as possible after posterior lumbar spine surgery. Therefore, most patients need to urinate while lying flat. In this position, there is a high risk of urine reflux. Urine reflux into the surgical incision site can soak the dressing, increase the probability of infection, and hinder wound healing. In the most severe cases (e.g., a weakened immune system leading to an infected surgical incision that cannot heal), it can lead to surgical failure.

[0010] At the same time, even if the patient does not experience urine reflux, the sweat can still soak the surgical incision when the patient sweats on their back due to hot weather (or a constitution that is intolerant to heat and prone to sweating), pain, or other reasons.

[0011] In view of the above problems, the present application provides a lumbar surgery incision protection device for orthopedics, which comprises a shell, a detection module and a processor. The shell is used for sleeving the waist of a patient to fix the detection module; the detection module is arranged on the inner side of the shell to detect the state of the patient's surgical incision; and the processor can receive information sent by the detection module to generate an alarm signal or control the execution module to provide a dehumidification operation for the area where the patient's surgical incision is located.

[0012] When the humidity data of the area where the patient's surgical incision is located detected by the detection module is higher than the first threshold value, the processor generates one or more of the following operations: sending an alarm trigger instruction to a terminal for reminding medical staff; sending a working instruction to an execution module capable of reducing the humidity of the area where the patient's surgical incision is located, wherein the working instruction includes providing illuminating light for promoting wound healing for the patient's surgical incision and / or detecting the smell of the liquid in the area where the patient's surgical incision is located, so as to provide corresponding dehumidification operation for the humidity state of the area where the patient's surgical incision is located.

[0013] The beneficial effects of the technical solution are as follows:

[0014] The lumbar protection device after lumbar surgery in orthopedics can protect and fix the lumbar vertebrae with postoperative wounds, and reduce the pain of the wound that may be caused by the movement of the patient's limbs by hindering the twisting of the waist, thereby creating conditions for early ambulation.

[0015] For patients undergoing lumbar surgery, the wearing time of the waist protection device is relatively long, and the longest time may last for 2 months. When wearing the waist protection device, the dressing material should be kept dry to avoid being soaked by sweat, moisture or other liquids.

[0016] For patients who do not want to insert a urinary catheter (lumbar surgery does not require the insertion of a urinary catheter), there is a risk of urine leakage or surgical wound oozing pus in the early stage of surgery. During this process, the liquid will soak the patient's dressing, contaminate the patient's wound and delay the healing time of the patient's surgical wound.

[0017] Compared with the lumbar protection device after lumbar surgery in orthopedics in the prior art, which tightly wraps the waist of the patient so that the third party cannot observe the wound condition, the present technical solution is designed to address the problem of liquid soaking the wound that may occur during the wearing process of the patient.

[0018] The present technical solution can timely alarm medical staff when the patient has urine backflow or back sweat, and reduce the humidity of the area where the patient's surgical incision is located through baking or other methods when the medical staff cannot arrive in time.

[0019] The surgical incision of the orthopedic lumbar posterior open surgery is generally distributed on the back, and the surgical incision on the back is covered when the patient is in a lying state, so it is difficult for medical staff on patrol, caregivers or family members to discover that the surgical incision is wet at the first time. Based on the first detection unit arranged close to the surgical incision of the patient in the technical solution, the processor can feedback the humidity of the surgical incision to the medical staff in time, especially when the humidity of the surgical incision exceeds the first threshold value, it indicates that the surgical incision is wetted by body fluid or other liquid. Especially when the patient wets the dressing due to sweating on the back because there is no air conditioner in the ward or pain, the third party monitor or medical staff cannot observe it because it is wrapped by the waist protection device, and can only open the waist protection device through the patient's oral description when the wound responds to feedback, and replace the dressing. This lag in discovery greatly delays the healing speed of the wound, and increases the risk of wound infection for people with weak immunity.

[0020] According to a preferred embodiment, the detection module comprises a first detection unit capable of collecting humidity data of the area where the surgical incision of the patient is located, wherein when the humidity data detected by the first detection unit is higher than the first threshold value and lower than the second threshold value, the processor generates first control instructions comprising the following operations: sending an alarm trigger instruction to the terminal of the medical staff; detecting the smell of the liquid in the area where the surgical incision of the patient is located, wherein the terminal of the medical staff sending the alarm is the terminal of the medical staff positioned at the nurse station.

[0021] The beneficial effects of the technical solution are:

[0022] The technical solution divides the upper limit of the threshold value into at least two levels based on different physiological states of the patient or different states of the wound surrounding environment. Preferably, medical staff can make more detailed level division according to different situations. For example, in winter, the wound healing speed is fast, and the incidence of back sweat is low, so two levels of threshold value division are used. In summer, the wound healing speed is slow, and is greatly affected by temperature and humidity, and the number of patients with this condition is large, so more levels of threshold value can be divided to facilitate medical staff to judge the priority level of dressing replacement for each patient.

[0023] For example, in summer, the number and degree of back sweat of the patient will increase, and the operation time of replacing the dressing is longer, therefore, for different back sweat conditions of the patient, it is necessary to make fine classification so that medical staff can distinguish the degree of contamination of the dressing, and thus judge the patient who needs to replace the dressing more preferentially. For example, when the back sweat occurs and the dressing or wound is not wetted, the medical staff can preferentially handle the patient whose dressing or wound is wetted.

[0024] In the technical solution, the classification according to the wetness of the wound or dressing of the patient can more accurately reflect the state and healing process of the wound. The wetness of the wound is related to factors such as the depth of the wound, infection, exudation, and necrosis, and different wetness of the wound requires different treatment methods and dressings. According to the classification of wetness, medical staff can better evaluate the actual situation of the wound and choose the appropriate treatment plan.

[0025] When medical staff face multiple alarms at the same time, the classification according to the wetness of the wound or dressing of the patient, rather than the order of classification, has the following advantages:

[0026] Medical staff can prioritize high-risk wounds. According to the wetness of the wound or dressing, medical staff can judge the risk of infection and healing obstacles of the wound. Generally, the higher the wetness, the greater the risk of infection and the more serious the healing obstacles. Therefore, medical staff can prioritize high-risk wounds according to the wetness and change dressings in time to prevent the spread of infection and the worsening of the wound.

[0027] The efficiency and quality of nursing of medical staff are improved. According to the wetness of the wound or dressing, medical staff can judge the treatment needs and dressing selection of the wound. Generally, different wetness of the wound requires different types and performance of dressings. Therefore, medical staff can prepare appropriate dressings and tools in advance according to the wetness to reduce nursing time and cost. At the same time, medical staff can also adjust the frequency of dressing change and observation interval according to the wetness to improve the quality of nursing.

[0028] In particular, frequent alarms of the terminal of medical staff can cause a decrease in the work efficiency of medical staff. For patients with less serious conditions (wetness data below the second threshold), the priority of the alarm is low, and the alarm can be sent to the nurse station. Medical staff working in the nurse station with relatively low intensity can go to the ward for debridement, avoiding the situation where medical staff put down more serious patients to change dressings for less serious patients.

[0029] According to a preferred embodiment, when the wetness data detected by the first detection unit is higher than the second threshold, the processor generates a second control instruction containing the following operations: sending an alarm trigger instruction to a terminal capable of reminding medical staff; detecting the smell of liquid in the area where the patient's surgical incision is located; sending a work instruction to an execution module capable of reducing the wetness of the area where the patient's surgical incision is located, the second threshold is higher than the first threshold, the priority of the alarm in the second control instruction is higher than the priority of the alarm in the first control instruction, wherein the priority of the alarm refers to the number of medical staff to whom the alarm is sent and the degree of urgency represented by the alarm.

[0030] The beneficial effects of the technical solution are:

[0031] The alarm in the present application is dynamically changed, that is, as the degree of the patient deepens (for example, the back is wet with sweat and the humidity data is lower than the second threshold value at 10 o'clock in the morning, but because the patient is obese, the humidity data of the back is higher than the second threshold value after 15 minutes, or the patient is anemic, the humidity data of the back is lower than the first threshold value after 15 minutes), the priority of the alarm is upgraded or downgraded.

[0032] In this process, the new humidity data triggers the change of the alarm priority to prevent medical staff from doing useless work or failing to treat serious patients in time.

[0033] According to a preferred embodiment, the first rule for generating the first control instruction is lower than the second rule for generating the second control instruction. Preferably, the first rule and the second rule contain the judgment rule of the humidity data. Preferably, the judgment rule of the humidity data is that the humidity data is higher than the first threshold value and lower than the second threshold value or the humidity data is higher than the second threshold value. Since the postoperative patient has many risk physiological values, the system designed in the present application can be embedded in other numerical monitoring systems disclosed in the prior art. The first rule proposed in the present application can make the humidity data one of the patient physiological detection set. For example, the patient's blood oxygen is lower than the preset value and the humidity data is higher than the threshold value, which is the first rule. By combining the detection methods of multiple physiological parameters, the cause of the patient's wound contamination can be accurately judged to provide a basis for medical staff to provide relevant diagnosis and treatment.

[0034] According to a preferred embodiment, the detection module contains a second detection unit capable of collecting odor. When the detection module detects that the liquid in the area of the patient's surgical incision belongs to the surgical incision discharge liquid, the processor will adjust the alarm sent to the terminal of the medical staff to the highest priority. The second detection unit can at least classify the detected liquid into two categories. The first category is the surgical incision discharge liquid, for example, cerebrospinal fluid, fat liquefied liquid, inflammatory liquid. The second category is the non-surgical incision discharge liquid, for example, urine, sweat.

[0035] The highest priority of the alarm triggering instruction means that the number of terminals of medical staff to which the alarm triggering instruction is sent is the largest, and the emergency degree represented by the alarm displayed in the terminal of the medical staff is the highest.

[0036] The beneficial effects of the present technical solution are:

[0037] There are many ways for the patient's surgical incision to be wet, including the patient's back being wet with sweat, the patient's urine wetting the surgical incision when urinating, or cerebrospinal fluid flowing out of the surgical incision, etc.

[0038] The above-mentioned multiple possible wetting of the surgical incision cases have different degrees of impact on the surgical incision. The surgical incision is generally covered with a dressing. For example, the back sweat caused by pain or high temperature does not produce the amount of liquid that can soak the dressing and affect the recovery of the surgical incision, but the accumulation of sweat at this location can cause the dressing to fall off the surgical incision or cause bedsores on the skin at this location, and such problems can be handled in advance by baking and the like, and then the medical staff can determine whether further treatment is needed by observing the surgical incision.

[0039] Similarly, when the patient's surgical incision is significantly wet, the surgical incision is contaminated, and the method of reducing the surgical incision by baking and the like cannot solve the problem of contamination of the surgical incision. Therefore, when the humidity of the surgical incision is higher than the second threshold value, the medical staff needs to provide emergency assistance to clean the surgical incision.

[0040] When the humidity data collected by the first detection unit is higher than the first threshold value and lower than the second threshold value, the second detection unit is turned on. When the second detection unit detects that the liquid is the first type, the processor generates a first control instruction comprising the following operations. When the second detection unit detects that the liquid is the second type, the processor generates a second control instruction comprising the following operations.

[0041] When the liquid in the area where the patient's surgical incision is located detected by the detection module belongs to the non-surgical incision discharge liquid, the first detection unit continues to work until the area where the patient's surgical incision is located is lower than the first threshold value.

[0042] In response to the data collected by the first detection unit being higher than the second threshold value, the second detection unit stops working.

[0043] Preferably, when the second detection unit detects that the liquid is the first type, the first control instruction generated by the processor can be sent to at least one doctor and at least one nurse responsible for the patient at the same time. Based on the data collected by the first detection unit being higher than the second threshold value, the first control instruction generated by the processor is sent to at least one nurse responsible for the patient.

[0044] When the surgical incision flows cerebrospinal fluid, fat liquefied fluid, and inflammatory fluid, the cause of the problem is most likely to be postoperative sequelae or problems with the prognosis of the operation, therefore, simply treating the surgical incision and the surrounding skin tissue cannot solve the problem, and the doctor needs to intervene and treat in time.

[0045] However, when the liquid is urine or sweat, the biggest problem for the surgical incision is the falling off of the dressing and the contamination of the surgical incision, therefore, in this case, only the medical staff needs to clean the surgical incision and replace the dressing.

[0046] According to a preferred embodiment, the execution module comprises a wound baking lamp, wherein the wound baking lamp stops working when the first detection unit detects that the humidity data of the area where the surgical incision of the patient is located is lower than the first threshold value, or when the continuous working time of the wound baking lamp exceeds the preset single working time. Preferably, the medical staff can preset the single working time of the wound baking lamp according to the power of the wound baking lamp. For example, when the wound baking lamp is 20W, the preset single working time can be 5min. In the present technical solution, when the humidity data is always lower than the first threshold value, the working of the wound baking lamp whose continuous working time exceeds the preset single working time is suspended rather than terminated, that is, the working time of the wound baking lamp is calculated from zero when the stop working time exceeds the preset time. However, when the humidity data is always higher than the first threshold value, the working of the wound baking lamp is terminated rather than suspended, that is, the wound baking lamp will not be turned on again until the next humidity data is detected to be higher than the first threshold value.

[0047] The beneficial effects of the present technical solution are:

[0048] The baking method adopted in the present technical solution is a wound baking lamp. The wound baking lamp belongs to a physical treatment method, which uses the heat radiation of the baking lamp to act on the human body, can expand capillaries, promote blood circulation, enhance local tissue cell metabolism, promote the absorption and subsidence of wound swelling, and is beneficial to the absorption and subsidence of inflammation, thereby reducing the probability of wound infection. The wound baking lamp can regulate the metabolism of local tissue cells, relieve muscle soft tissue spasm, reduce the sensitivity of nerve endings, has an antispasmodic and analgesic effect, and can improve the movement of the limbs. The wound baking lamp can reduce tissue fluid exudation, relieve local inflammatory reaction, keep the wound site clean and dry, and is beneficial to the normal healing of the wound.

[0049] According to a preferred embodiment, the detection module further comprises a third detection unit for detecting temperature. When the wound baking lamp is turned on, the third detection unit is turned on. The working state of the wound baking lamp comprises a working state and a suspended state, wherein the wound baking lamp changes between the suspended state and the working state based on the humidity data detected by the first detection unit or the temperature data detected by the third detection unit. The suspended state means that the wound baking lamp is turned off. The working state means that the wound baking lamp is turned on.

[0050] According to a preferred embodiment, when the humidity data detected by the first detection unit is higher than the first threshold value and lower than the second threshold value, the wound baking lamp and the third detection unit are in working state. When the temperature data detected by the third detection unit is higher than the third threshold value, the wound baking lamp changes from working state to suspended state, and when the temperature data detected by the third detection unit is lower than the third threshold value, the wound baking lamp changes from suspended state to working state. When the humidity data detected by the first detection unit is lower than the first threshold value, the wound baking lamp changes from working state to suspended state, and the third detection unit stops working. Preferably, the third threshold value is 37-50℃.

[0051] According to a preferred embodiment, the wound baking lamp can provide at least two irradiation modes of light intensity for the patient based on the humidity data. Preferably, when the humidity data detected by the first detection unit changes but is lower than the first threshold value, the wound baking lamp can provide an irradiation mode of light intensity of the first power for the patient. When the humidity data detected by the first detection unit is higher than the first threshold value, the wound baking lamp can provide an irradiation mode of light intensity of the second power for the patient. The first power is less than the second power. Particularly preferably, the first power can be 10-90W. The second power can be 20-100W.

[0052] According to a preferred embodiment, when the patient enters the excretion stage (or the non-surgical exudate continuously wets the surgical dressing), the first detection unit can change from the first detection frequency to the second detection frequency, wherein the first detection frequency is higher than the second detection frequency. Preferably, when the data collected by the first detection unit is higher than the first threshold value, the second detection unit is triggered. When the second detection unit detects that the liquid is urine, the first detection unit can change from the first detection frequency to the second detection frequency. Preferably, the first detection frequency is 1 min / time-20 min / time. The second detection frequency is 1 s / time-1 min / time.

[0053] The beneficial effects of the technical solution are as follows:

[0054] For patients who urinate in a lying state, the flow path of urine is easy to pass through the back and contaminate the surgical incision distributed on the back. In particular, during the patient's urination process, the caregiver or family member taking care of the patient needs to provide the patient with a urination tool, and the patient's urination process is relatively rapid and cannot be responded in time, so the patient's urination time is very easy to occur in the time period of contaminating the surgical incision.

[0055] Therefore, when the patient excretes, the first detection unit can respond in time to feedback the wetting condition of the surgical incision to medical staff and family members, and make timely treatment after the patient finishes excretion.

[0056] According to a preferred embodiment, the shell comprises a back plate on which the first detection units are arranged at several positions, and side support plates connected to both sides of the back plate, wherein at least one of the first detection units is located on the inner side of the back plate corresponding to the position of the surgical incision. Preferably, the first detection units are arranged along one side of the back plate towards the lower limbs of the patient, and towards the other side of the back plate towards the head of the patient, so that the non-surgical incision liquid is detected by the first detection units in advance when flowing towards the area where the surgical incision of the patient is located.

[0057] According to a preferred embodiment, at least one of the side support plates is provided with an air bag, wherein when the humidity data detected by the first detection units is higher than a second threshold value, the air bag is inflated to elevate at least one side of the waist of the patient, so that the surgical incision of the patient can be away from the position where it is attached.

[0058] The beneficial effects of the technical solution are:

[0059] In the case of a large volume of contaminated liquid, the liquid will accumulate on the bed and soak the surgical incision for a long time. The technical solution elevates the waist by the air bag, so that the surgical incision can be away from the position where the liquid accumulates.

[0060] According to a preferred embodiment, the top and bottom of the side support plate is provided with an extendable extension plate, wherein the panel formed by the extension plate and the side support plate is arranged in an arc shape to match the lateral waist line of the patient.

[0061] According to a preferred embodiment, at least one of the side support plates is provided with an air bag, so that when the patient is lying down, one side of the waist is always elevated.

[0062] According to a preferred embodiment, based on the position deviation of the surgical incision, the processor can control the air bag on the side close to the surgical incision to inflate at a higher frequency than the air bag on the side away from the surgical incision.

[0063] According to a preferred embodiment, the processor controls the side support plates arranged on both sides to inflate alternately. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0069] The application will be described in detail below with reference to the accompanying drawings.

[0070] In the present application, the inner side of the device refers to the side facing the patient. The outer side of the device refers to the side facing away from the patient. The area where the surgical incision is located refers to the surgical incision on the back after lumbar surgery and the skin tissue around it. The skin tissue around it involved in the definition refers to the skin tissue affecting the healing of the surgical incision.

[0071] When the wound baking lamp 310 irradiates for a long time, the healing temperature of the surgical incision will continue to increase, which will increase to a high temperature that is not conducive to the healing of the surgical incision and even damage the skin tissue. Therefore, in the present application, the preset single working time refers to the temperature accumulated by the wound baking lamp 310 for the surgical incision within the preset single working time is conducive to wound healing. Preferably, the preset single working time can be 1-20 min.

[0072] The top of the side support plate 120 refers to the part facing the patient's chest. The bottom of the side support plate 120 refers to the part facing the patient's lower limbs. The top of the side support plate 120 is in the same direction as the upper part of the extension plate 122. The bottom of the side support plate 120 is in the same direction as the lower part of the extension plate 122. The upper part of the extension plate 122 refers to the part facing the patient's chest. The lower part of the extension plate 122 refers to the part facing the patient's lower limbs.

[0073] The deviation of the position of the surgical incision refers to that when the surgical incision is located on both sides of the spine, it has a deviation relative to the spine. Preferably, when the surgical incision is located on the left side of the spine, the air bag 121 provided on the side support plate 120 on the right side can be inflated or inflated in a mode with a larger volume than the left air bag 121, so that the body is inclined at an inclination of the left side being higher and the right side being lower, so that the surgical incision located on the left side of the spine can not be compressed.

[0074] The lateral waist line of the patient refers to a line of muscle groups extending from the lower edge of the hip bone to the intercostal space. The partial area of the side support plate 120 will interfere with the waist line, so that the protection device can be stably sleeved on the patient's body.

[0075] The first control instruction and the second control instruction are used to trigger the execution module 300 and / or the prompt module to start operation.

[0076] Embodiment 1

[0077] The present application provides a surgical incision protection device for lumbar vertebrae surgery in orthopedics, which comprises a shell 100, a detection module 200 and a processor 400. The shell 100 is sleeved on the waist of a patient. The detection module 200 is arranged on the inner side of the shell 100 to detect the state of the surgical incision of the patient. The detection module 200 further comprises a first detection unit 210 capable of collecting humidity data of the area where the surgical incision of the patient is located. In response to the humidity data detected by the first detection unit 210 being higher than a first threshold value, the processor 400 generates one or more of the following operations: sending an alarm trigger instruction to a terminal capable of reminding medical staff; sending a work instruction to an execution module 300 capable of reducing the humidity of the area where the surgical incision of the patient is located. Preferably, the first threshold value is 60% to 80%.

[0078] In response to the humidity data detected by the first detection unit 210 being higher than the first threshold value and lower than a second threshold value, the processor 400 generates one or more of the following operations: sending a first-level alarm trigger instruction to a terminal capable of reminding medical staff. When the humidity data detected by the first detection unit 210 is higher than the second threshold value, the processor 400 generates a second control instruction comprising the following operations: sending a second-level alarm trigger instruction to a terminal capable of reminding medical staff; sending a work instruction to an execution module 300 capable of reducing the humidity of the area where the surgical incision of the patient is located. Preferably, the second threshold value is 70% to 100%. The first-level alarm refers to an emergency alarm, which has a higher priority than the second-level alarm. It is particularly preferred that the second-level alarm is an information broadcast, that is, an alarm information is sent to the terminal of the medical staff responsible for the patient. The first-level alarm is a voice broadcast, that is, the broadcast information is sent to the terminal of the medical staff responsible for the patient and the nurses' station at the same time in a more eye-catching broadcast manner than the second-level alarm.

[0079] According to a preferred embodiment, the execution module 300 comprises a wound baking lamp 310, wherein the wound baking lamp 310 stops working when the first detection unit 210 detects that the humidity data of the area where the surgical incision of the patient is located is lower than the first threshold value, or when the continuous working time of the wound baking lamp 310 exceeds the preset single working time. Preferably, the wound baking lamp 310 is an infrared radiator. The wound baking lamp 310 performs infrared radiation heating on the surgical incision, thereby promoting the surgical incision to recover dryness as soon as possible, so as to reduce the risk of infection.

[0080] The following is an example:

[0081] The patient wears the orthopedic lumbar surgery incision protection device after surgery and remains flat on the bed. Preferably, the first threshold is set to 65%. The second threshold is set to 75%. The third threshold is set to 40°C.

[0082] When the patient urinates on the bed, urine flows through the position of the surgical incision patch dressing. The first detection unit 210 sends the detected humidity data to the processor 400. Based on the current humidity data of 70%, the processor 400 triggers the second detection unit 220, the wound baking lamp 310 and the third detection unit 230 to start working, and sends a secondary alarm to the medical staff terminal, as shown. Figure 3 Based on the confirmation of the second detection unit 220 that the liquid with increased humidity is urine, the first detection unit 210 changes its first detection frequency of 1 min / time to a second detection frequency of 10s / time.

[0083] When the third detection unit 230 detects that the temperature reaches 40°C, the wound baking lamp 310 turns to the suspended state, and when the third detection unit 230 detects that the temperature is lower than 40°C, the wound baking lamp 310 enters the working state with a power of 40W.

[0084] Preferably, if the urine stops wetting the surgical incision, when the humidity data collected by the first detection unit 210 is lower than 65%, the third detection unit 230 stops working, and the wound baking lamp 310 enters the termination state.

[0085] Further, when the patient's urine continuously wets the surgical incision, the humidity data collected by the first detection unit 210 gradually increases until the humidity data is higher than 75%. The third detection unit 230 stops working, the wound baking lamp 310 enters the termination state, and the processor 400 sends a primary alarm to the medical staff terminal to prompt the medical staff to immediately check the surgical incision of the patient and clean the surgical incision.
