Description

Technical Field

[0001] The present invention relates to the technical field of patient walking assistance devices, and in particular to a walking assistance device for patients after pancreatic surgery that combines drainage and fall prevention functions. Background Art

[0002] The pancreas is an organ located deep in the abdominal cavity. It is responsible for secreting a variety of digestive enzymes and hormones (such as insulin and glucagon), which are essential for food digestion and absorption and blood sugar regulation. Pancreatic surgery refers to various surgical treatments for the pancreas, including but not limited to pancreatic tumor resection, treatment of pancreatitis, and partial or complete pancreatectomy. After surgery, exudate or blood accumulation may occur around the pancreas, and these effusions need to be removed through drainage cannulas to prevent the formation of encapsulated effusions or infections. Within 2-7 days after pancreatic surgery, the doctor will encourage the patient to get out of bed and move around according to the patient's condition to promote blood circulation, prevent thrombosis, and accelerate the recovery of intestinal function. In the early stage of getting out of bed and walking, the patient is relatively weak and needs someone to accompany him or her throughout the process or borrow walkers, crutches and other assistive devices to ensure stable walking.

[0003] At present, most common walkers on the market only have auxiliary support functions, and do not have the function of predicting or preventing falls. Therefore, even if patients use walkers, they still need family members or nurses to accompany them throughout the early stage of getting out of bed to avoid falls caused by physical weakness, physical exhaustion or other accidents. However, full accompaniment will not only increase the difficulty and cost of postoperative care, but also reduce the patient's willingness to get out of bed to a certain extent, which is not conducive to the patient's mental health and physical recovery. In addition, when patients get out of bed to walk, they need to carry external drainage tubes and drainage bags, which will increase the risk of the drainage tube being pulled or falling off. Summary of the invention

[0004] The present invention aims to provide a pancreatic surgery walking assistance device with both drainage and fall prevention functions, which can predict and intervene in the patient's stable walking. When the patient feels uncomfortable while walking outside or is physically weak and lacks strength, the patient's location can be sent to the nurse station in time and the protection mechanism can be activated to reduce the risk of falling.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A post-pancreatic surgery walking assist device with both drainage and fall prevention functions, comprising a four-corner bracket for assisting walking and a detachable abdominal belt on the bracket, a wheel assembly is provided at the bottom of the bracket, and two handrails are provided at the top of the bracket; a fixing clip for fixing a drainage tube and a storage bag for placing a drainage bag are provided on the abdominal belt, and a protective assembly for protecting the drainage bag is also provided outside the storage bag;

[0007] A gripping force detection module is provided on the armrest, a locking assembly is provided on the wheel assembly, and a control system is also provided on the bracket. The control system includes a controller and a positioning module and a voice call module electrically connected to the controller. The gripping force detection module, the locking assembly, and the protection assembly are all electrically connected to the controller;

[0008] The gripping force detection module is used to detect the patient's gripping strength in real time and send the detected signal to the controller. After receiving the signal, the controller analyzes and processes the data, and the analysis results include normal and abnormal. When the analysis result is abnormal, the controller is used to control the locking component and the protection component to start, the locking component locks the wheel assembly, and the protection component protects the drainage bag. At the same time, the controller controls the positioning module and the voice call module to start. The voice call module is used to make voice calls with the mobile terminal or the computer terminal at the nurse station, and the positioning module is used to send the current position to the mobile terminal and the computer terminal.

[0009] Beneficial effects:

[0010] 1. When the patient is walking normally, both hands should continue to hold the handrails and apply a certain amount of thrust and grip to the handrails. By setting a gripping force detection module on the armrest of the bracket, the patient's gripping force can be monitored in real time, so as to judge the patient's physical condition according to the gripping force; if the patient is physically weak due to physical weakness, or if he or she suffers from dizziness, nausea, palpitations and other symptoms after getting out of bed and walking in the early stage, his or her gripping force will be reduced; once the controller analyzes the signal as abnormal, it immediately controls the locking component, protection component, positioning module, and voice call module to start;

[0011] Among them, after the locking assembly is activated, the wheel assembly of the bracket is locked, thereby limiting the bracket from further displacement and improving the stability of the bracket. At this time, the patient can lean on the bracket to take a short rest and wait for the accompanying personnel to come to help, which can effectively reduce the risk of the patient falling due to the movement of the bracket;

[0012] The protection component is activated to protect the drainage bag, which can prevent the drainage bag from being separated from the storage bag, being damaged, and causing the drainage tube to be pulled or falling off when the patient really falls. In particular, it can effectively prevent the drainage bag and the drainage tube from falling off when the patient falls, or the drainage tube from falling off the patient's body, causing secondary injuries, such as wound pulling, air entering and infection, etc.

[0013] When the voice call module is activated, it can communicate with the nurse station remotely, which is beneficial for nurses to communicate with patients in time and understand the specific situation in time; the positioning module is activated to send the patient's location to the nurse's computer or mobile terminal (such as a mobile phone), so that the nurse can find the patient in time and provide help to the patient; for example, when the patient is unwell, it is difficult for one person to walk back to the ward. At this time, the nurse can go to the patient in time to help the patient return to the bed to rest, which can avoid the risk of the patient falling when returning independently.

[0014] 2. By setting up an abdominal belt, when the patient gets out of bed and walks, the abdominal belt can be removed from the bracket and tied to the body, which can provide certain support for the patient's abdominal muscles, reduce the pressure or tearing of the wound caused by abdominal muscle activity caused by walking, and help protect the surgical incision; in addition, a fixing clip and a storage bag are set on the abdominal belt to fix the drainage tube and the drainage bag, reduce the risk of the drainage tube being pulled, and prevent the drainage tube from loosening or falling off due to getting out of bed.

[0015] Preferably, as an improvement, it further includes a forced intervention module and a pre-processing module, the forced intervention module is used to start the locking component, the protection component, the voice call module and the positioning module, the pre-processing module includes a voice reminder submodule, the voice reminder submodule is used to send a voice reminder to the patient, and receive the patient's voice reply and send it to the controller;

[0016] When the holding force detection modules on the armrests on both sides of the bracket do not detect any signal, the controller controls the forced intervention module to start, which is used to start the locking component, the protection component, the voice call module and the positioning module; when the holding force detection module on either side of the armrest detects a signal and the other holding force detection module does not detect a signal, the controller controls the preprocessing module to start, and the voice reminder submodule is used to issue a voice reminder to the patient. When the patient confirms the voice reminder, the voice reminder submodule sends a signal to the controller. After receiving the signal, the controller controls the forced intervention module to start. Otherwise, the forced intervention module will not be started and the preprocessing module will be closed.

[0017] Beneficial effects: By classifying the gripping force on both sides, it is helpful to improve the accuracy of intervention and reduce misjudgment; for example: when the patient walks normally, both hands should hold the handrails. When the gripping force detection modules on both sides do not detect signals, it means that the patient's hands have left the handrails. At this time, it can be inferred that the patient is likely to have fallen, and it is necessary to immediately start various components and modules for intervention; when no signal is detected on one side of the patient's handrail, but a signal is detected on the other side, the voice reminder module is started first to remind the patient whether he needs help. When the patient confirms that he needs help, various components and modules are started, which effectively improves the accuracy of intervention.

[0018] Preferably, as an improvement, the abdominal band includes a wound area and support areas located on both sides of the wound area, straps are also provided at the left and right ends of the support area, the wound area and the support area are detachably connected, and a notch is also provided on the wound area for the drainage tube to pass through; a fixing area is also provided below the wound area and the support area, and a fixing clip and a storage bag are provided on the fixing area.

[0019] Beneficial effects: The abdominal belt can provide multiple supports and protections for patients after pancreatic surgery, for example: using the wound area to protect the wound, using the support area to provide abdominal support, setting a fixed area to facilitate the fixation of the drainage tube and the carrying of the drainage bag, and the wound area is detachable for easy replacement. This setting not only helps to reduce postoperative complications and improve the patient's comfort, but also enhances the patient's confidence in getting out of bed and promoting recovery.

[0020] Preferably, as an improvement, a supporting airbag and a pressure sensor for detecting the pressure of the supporting airbag are provided on the supporting area; the protective component is a negative pressure airbag, which is provided on the outside of the storage bag; the negative pressure airbag is connected to the supporting airbag through a connecting tube, and a switch valve is also provided on the connecting tube; a power supply part is also provided on the fixed area, and the pressure sensor and the switch valve are electrically connected to the power supply part, and are communicatively connected with the controller on the bracket; the controller is used to control the opening of the switch valve, and the gas in the supporting airbag enters the negative pressure airbag through the connecting tube.

[0021] Beneficial effects:

[0022] 1. By setting the support airbag and pressure sensor, appropriate support force can be applied according to different patients to avoid the abdominal belt being too loose or too tight, thereby improving the comfort of use.

[0023] 2. A negative pressure airbag is set outside the storage bag. When the patient is physically exhausted or other unexpected situations cause his hands to leave the armrests, the controller controls the switch valve to open, and the gas in the support airbag is transferred to the negative pressure airbag; the inflation of the negative pressure airbag can protect the drainage bag, and prevent the drainage bag from being damaged and detached from the storage bag when the patient really falls, which in turn causes the drainage tube to be pulled or fall off.

[0024] 3. When the patient is physically exhausted, the gas in the support airbag can be released into the negative pressure airbag to appropriately reduce the pressure on the abdomen, relieve the burden and improve comfort.

[0025] Preferably, as an improvement, a storage area is further provided on the upper side wall of the abdominal belt and the lower side wall of the fixed area, and an airbag and an inflation assembly are provided in the storage area. A six-axis sensor and a collision sensing sensor which are communicatively connected to the controller and electrically connected to the power supply part are also provided on the storage area; when the controller receives signals from the six-axis sensor and the collision sensing sensor within a preset time and does not receive signals from the gripping force detection modules on the armrests on both sides, the controller controls the inflation assembly to inflate the airbag, and the airbag pops out from the storage area after inflation.

[0026] Beneficial effects: By simultaneously monitoring the six-axis sensor, collision-sensing sensor, and grip force detection module as the conditions for triggering the airbag, the accuracy of the judgment can be improved and invalid activation can be reduced; when the patient really falls, the airbag inflates and pops out, which can provide a certain degree of protection for the patient and avoid secondary injuries caused by direct contact and friction with the ground. In addition, it is worth noting that when the patient falls, the gas in the support airbag on the abdominal belt has been released. At this time, only the airbags on the upper and lower sides of the abdominal belt are inflated and in contact with the ground, and the support airbag on the abdominal belt does not contact the ground, which can avoid the reaction force generated when the support airbag contacts the ground to squeeze the abdomen, thereby causing secondary injuries to the abdominal wound area.

[0027] Preferably, as an improvement, the locking assembly includes a brake handle, a brake hose, and a brake caliper, the brake caliper is arranged on the wheel assembly, and the brake caliper is connected to the brake handle through the brake hose; a driving member is also arranged on the bracket, a power output end of the driving member is hinged to the brake handle, and the driving member is electrically connected to the controller; when the forced intervention module is started, the controller controls the action of the driving member, and the driving member drives the brake handle to apply friction resistance to the wheel assembly, so as to lock the wheel assembly.

[0028] Preferably, as an improvement, the bracket is provided with a placement rack for placing the belly band, and the placement rack is provided with a card slot and a charging port; the card slot is used to cooperate with the fixing clip, and a charging head is provided on the fixing area. When the fixing clip is inserted into the card slot, the charging head on the fixing area is inserted into the charging port on the placement rack.

[0029] Beneficial effect: When the patient does not get out of bed to walk, the abdominal belt is placed on the placement frame, and the abdominal belt is fixed to the slot of the placement frame using the fixing clip for fixing the drainage tube. The abdominal belt can be limited in position, and the limiting effect can be used to make the charging head on the abdominal belt correspond to the charging port on the placement frame, thereby charging the power supply part on the fixed area.

[0030] Preferably, as an improvement, an inflation pump and an exhaust pump are also provided on the placement rack, the inflation pump is provided with an inflation tube, and the exhaust pump is provided with an exhaust tube; the support airbag on the abdominal belt is provided with an air inlet for connecting with the inflation tube, the negative pressure airbag is provided with an air outlet for connecting with the exhaust tube, and sealing plugs are provided on both the air inlet and the air outlet.

[0031] Beneficial effects: When the abdominal belt is tied on the patient, the inflation tube is connected to the air inlet on the support airbag, and the support airbag is inflated using an inflation pump; when the abdominal belt is removed, the outlet tube is connected to the negative pressure airbag, and the gas in the negative pressure airbag is extracted using an exhaust pump.

[0032] Preferably, as an improvement, a sterile cloth layer is used in the wound area, and ears are provided on both sides of the sterile cloth layer. A magic tape is provided on the side wall of the support area for connecting with the sterile cloth layer, and the magic tape passes through the ears and is fixed to the support area.

[0033] Beneficial effects: The magic tape is used to facilitate the quick removal and replacement of the sterile cloth layer. The wound area is close to the patient's wound site, and the sterile cloth layer is softer and more breathable. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Embodiment 1

[0046] like Figure 1-2 As shown, a postoperative pancreatic walking assist device with both drainage and fall prevention functions includes a four-corner bracket 1 for assisting walking and a detachable abdominal belt 2 on the bracket 1. The abdominal belt 2 is provided with a fixing clip 3 for fixing the drainage tube 200 and a storage bag 4 for placing the drainage bag 201. The storage bag 4 is also provided with a protective component 103 for protecting the drainage bag 201. When the patient does not get out of bed to walk, the abdominal belt 2 is fixedly placed on the bracket 1. When the patient needs to get out of bed to walk, the abdominal belt 2 is first removed and fixed on the patient. The abdominal belt 2 can play a certain supporting role on the patient's abdominal muscles, reduce the pressure or tearing of the wound caused by the abdominal muscle activity caused by walking, and is conducive to protecting the surgical incision; in addition, the fixing clip 3 and the storage bag 4 on the abdominal belt 2 can fix the drainage tube 200 and the drainage bag 201, reduce the risk of the drainage tube 200 being pulled, and prevent the drainage tube 200 from loosening or falling off due to getting out of bed.

[0047] Specific as Figure 2 As shown, the abdominal band 2 includes a wound area 21 and support areas 22 located on both sides of the wound area 21. The left and right ends of the support area 22 are also provided with straps 221, and the abdominal band 2 is fixed to the patient by the straps 221; the wound area 21 is also provided with a notch 211 for the drainage tube 200 to pass through, and a fixing area 23 is also provided below the wound area 21 and the support area 22, and a fixing clip 3 and a storage bag 4 are provided on the fixing area 23; when in use, the drainage tube 200 is extended from the notch 211 on the wound area 21, and then fixed and limited by the fixing clip 3, and the drainage bag 201 is stored in the storage bag 4.

[0048] In this embodiment, the wound area 21 is made of a sterile cloth layer, which is softer and more breathable when used. The wound area 21 and the support area 22 are detachably connected. Specifically, ears 212 are provided on both sides of the sterile cloth layer, and magic tape 213 is provided on the side wall of the support area 22 for connecting with the sterile cloth layer. When in use, the magic tape 213 is passed through the ears 212 and then reversely fixed on the support area 22, which is convenient for quick disassembly and replacement.

[0049] like Figure 1 As shown, a wheel assembly 11 is provided at the bottom of the bracket 1, a locking assembly 13 is provided on the wheel assembly 11, two armrests 12 are provided on the top of the bracket 1, and a gripping force detection module 121 is provided on the armrests 12. Specifically, the gripping force detection module 121 adopts a pressure sensor; the bracket 1 is also provided with a control box 10, a main power supply for powering the electrical components in the control box 10, and a main switch for starting or shutting down the control box 100, and a control system is provided in the control box 10, such as Figure 3 As shown, the control system includes a controller 100 and a positioning module 101 and a voice call module 102 electrically connected to the controller 100, and a gripping force detection module 121, a locking assembly 13, and a protection assembly 103 are all electrically connected to the controller 100; in this embodiment, the controller 100 adopts a PLC controller.

[0050] The gripping force detection module 121 is used to detect the gripping force of the patient in real time, and send the detected signal to the controller 100. After receiving the signal, the controller 100 analyzes and processes the data. The analysis results include normal and abnormal. When the pressure detected by the gripping force detection module 121 is within the preset range, the controller 100 determines it as normal. When the detected pressure is less than or greater than the preset range, the controller 100 determines it as abnormal. When the analysis result is abnormal, the controller 100 is used to control the locking component 13 and the protection component 103 to start, the locking component 13 locks the wheel component 11, and the protection component 103 protects the drainage bag 201; at the same time, the controller 100 controls the positioning module 101 and the voice call module 102 to start, the voice call module 102 is used to make a voice call with the mobile terminal or the computer terminal of the nurse station, and the positioning module 101 is used to send the current position to the mobile terminal and the computer terminal.

[0051] like Figure 2As shown, a supporting airbag 222 and a pressure sensor for detecting the pressure of the supporting airbag 222 are provided on the supporting area 22 of the abdominal belt 2, and the protective component 103 is a negative pressure airbag 401, which is wrapped and arranged on the outside of the storage bag 4 and is higher than the storage bag 4, and the negative pressure airbag 401 is connected with the supporting airbag 222 through a connecting tube, and a switch valve 402 is also provided on the connecting tube; a power supply part is also provided on the fixed area 23, and the pressure sensor and the switch valve 402 are electrically connected to the power supply part, and are communicated with the controller 100 on the bracket 1, and the controller 100 is used to control the opening of the switch valve 402. When the switch valve 402 is opened, the gas in the supporting airbag 222 enters the negative pressure airbag 401 through the connecting tube, and the negative pressure airbag 401 is inflated to protect the drainage bag 201.

[0052] When the patient is walking normally, both hands should continue to hold the armrest 12 and apply a certain thrust and gripping force to the armrest 12. By setting a gripping force detection module 121 on the armrest 12 of the bracket 1, the patient's gripping force can be monitored in real time, so that the patient's physical condition can be judged according to the gripping force; if the patient is physically weak and lacks strength, the patient can hold the armrest 12 tightly and apply a larger gripping force to the armrest 12 within a certain period of time. When the gripping force is greater than the maximum value of the preset range, the controller 100 determines it as an abnormal result; or after getting out of bed and walking in the early stage, some patients may experience symptoms such as dizziness, nausea, and palpitations, resulting in physical weakness. At this time, the patient's gripping force on the armrest 12 will be reduced. When it is lower than the minimum value of the preset range, the controller 100 also determines it as an abnormal result, and immediately controls the locking component 13, the protection component 103, the positioning module 101, and the voice call module 102 to start.

[0053] More preferably, a heart rate detection module may be provided on the armrest 12. When the patient walks while holding the armrest 12, the heart rate detection module detects the heart rate in real time and sends a signal to the controller 100. When the detected heart rate becomes abnormal within a certain period of time, the controller 100 determines it as an abnormal result and immediately controls the locking component 13, the protection component 103, the positioning module 101, and the voice call module 102 to start.

[0054] Among them, after the locking assembly 13 is activated, the wheel assembly 11 of the bracket 1 is locked, thereby limiting the bracket 1 from further displacement and improving the stability of the bracket 1. At this time, the patient can lean on the bracket 1 to take a short rest and wait for the accompanying personnel to come to help, which can effectively reduce the risk of the patient falling due to the movement of the bracket 1.

[0055] The protection component 103 is activated to protect the drainage bag 201, so that when the patient really falls, the drainage bag 201 can be prevented from being separated from the storage bag 4 and being damaged, and the drainage tube 200 can be pulled or fallen off. In particular, it can effectively prevent the drainage bag 201 and the drainage tube 200 from falling off, or the drainage tube 200 from falling off the patient's body when the patient falls, causing secondary injuries, such as wound pulling, air entering and infection, etc.

[0056] When the voice call module 102 is started, it can communicate with the nurse station remotely, which is beneficial for the nurse to communicate with the patient in time and understand the specific situation in time; the positioning module 101 is started to send the patient's location to the computer or mobile terminal on the nurse side. The mobile terminal includes a mobile phone and a tablet, which is convenient for the nurse to find the patient in time and thus provide assistance to the patient; for example, when the patient is unwell, it is difficult for one person to walk back to the ward. At this time, the nurse can go to the patient in time to help the patient return to the bed to rest, which can avoid the risk of the patient falling if he returns independently.

[0057] Implementation II

[0058] The difference between this embodiment and the first embodiment is that Figure 4 As shown, it also includes a forced intervention module 1001 and a pre-processing module 1002. The forced intervention module 1001 is used to start the locking component 13, the protection component 103, the voice call module 102 and the positioning module 101; the pre-processing module 1002 includes a voice reminder sub-module 10021, and the voice reminder sub-module 10021 is used to issue a voice reminder to the patient, for example: whether help is needed, and receive the patient's voice reply and send it to the controller 100; when the controller 100 receives a signal for help, the forced intervention module 1001 is controlled to start, and when the controller 100 does not receive a signal confirming help within a preset time, the pre-processing module 1002 is controlled to shut down.

[0059] Specifically, when the gripping force detection modules 121 on the armrests 12 on both sides of the support 1 do not detect any signal, it means that the patient's hands have left the armrests 12 and a fall may have occurred. At this time, the controller 100 controls the forced intervention module 1001 to start, which is used to start the locking component 13, the protection component 103, the voice call module 102 and the positioning module 101. When the gripping force detection module 121 on either side of the armrest 12 detects a signal and the other gripping force detection module 121 does not detect a signal, the controller 100 controls the preprocessing module 1002 to start, and the voice reminder submodule 10021 is used to send a voice reminder to the patient. When the patient confirms the voice reminder, the voice reminder submodule 10021 sends a signal to the controller 100, and the controller 100 controls the forced intervention module 1001 to start. Otherwise, the forced intervention module 1001 is not started, and the preprocessing module 1002 is closed.

[0060] Preferably, the present embodiment also includes an education module, which may be implemented in the form of voice education or video education. The education module is used to inform the patient that when using the device to walk, both hands need to hold the armrest 12 at all times, or at least one hand needs to hold the armrest 12, so as to detect the patient's physical condition; when both hands do not hold the armrest 12, the forced intervention module 1001 will be activated for protection, thereby helping to further improve the accuracy of the detection and allowing the patient to use the device in a standardized manner.

[0061] Embodiment 3

[0062] The difference between this embodiment and the second embodiment is that Figure 5-6 As shown, the locking assembly 13 includes a brake handle 131, a brake oil pipe 132, and a brake caliper 133. The brake caliper 133 is arranged on the wheel assembly 11, and the brake caliper 133 is connected to the brake handle 131 through the brake oil pipe 132; the bracket 1 is also provided with a driving member 134, the power output end of the driving member 134 is hinged with the brake handle 131, and the driving member 134 is electrically connected to the controller 100. Specifically, the driving member 134 is a cylinder. When the forced intervention module 1001 is started, the controller 100 controls the driving member 134 to move, and the piston rod of the driving member 134 extends to drive the brake handle 131 to move and apply friction resistance to the wheel assembly 11, so as to lock the wheel assembly 11; the locking assembly 13 of this embodiment adopts the brake handle 131, brake oil pipe 132, and brake caliper 133 structure in the existing bicycle brake system, which will not be described in detail here.

[0063] Embodiment 4

[0064] The difference between this embodiment and the third embodiment is that Figure 7As shown, a storage area 5 is further provided on the upper side wall of the abdominal belt 2 and the lower side wall of the fixed area 23. The specific storage area 5 can adopt a bag structure or an elastic plate structure. More preferably, in this embodiment, the length of the storage area 5 arranged below the fixed area 23 is greater than the length of the fixed area 23, and auxiliary belts 51 are provided on the left and right sides of the storage area 5. When in use, the auxiliary belts 51 are tied to the patient's body, so as to better fix and limit the lower storage area 5. An airbag and an inflation assembly (not shown in the figure) are arranged in the storage area 5. A six-axis sensor 52 and a collision sensing sensor 53 which are communicatively connected to the controller 100 and electrically connected to the power supply unit are also arranged on the storage area 5. When the controller 100 receives the signals sent by the six-axis sensor 52 and the collision sensing sensor 53 within a preset time, and does not receive the signals sent by the gripping force detection module 121 on the armrests 12 on both sides, it indicates that the patient has fallen. At this time, the controller 100 controls the inflation assembly to inflate the airbag. After the airbag is inflated, it pops out from the storage area 5, which provides certain protection for the patient and avoids secondary injuries caused by direct contact and friction with the ground.

[0065] Specifically, the inflation component of this embodiment adopts an existing gas generator for instantaneous inflation of automobile airbags. Chemical substances such as sodium azide (NaN3) or ammonium nitrate (NH4NO3) are stored in the gas generator, which rapidly decomposes to generate a large amount of nitrogen when impacted, thereby instantly inflating the airbag. This will not be described in detail here. More preferably, in this embodiment, most of the fixed area 23 is located below the support area 22, and a small part is located below the wound area 21, so as to reduce the vibration of the wound area 21 caused by the airbag on the lower side wall of the fixed area 23 when it pops out; in addition, it is worth noting that when the patient falls, the gas of the support airbag 222 on the abdominal belt 2 in this embodiment has been released into the negative pressure airbag 401. At this time, only the airbags on the upper and lower sides of the abdominal belt 2 are inflated and in contact with the ground, and the support airbag 222 on the abdominal belt 2 does not contact with the ground, which can avoid the reaction force generated when the support airbag 222 contacts the ground to squeeze the abdomen, thereby causing secondary damage to the abdominal wound area 21.

Specifically, the fixing clip 3 in this embodiment adopts an elastic O-shaped pipe clip. When in use, the fixing clip 3 is inserted into the slot 61 to limit and fix the belly band 2. A charging head is also provided on the fixing area 23 of the belly band 2. When the fixing clip 3 is inserted into the slot 61, the charging head on the fixing area 23 is inserted into the charging port 62 on the placement rack 6 to charge the power supply part on the fixing area 23. More preferably, the charging head and the charging port 62 in this embodiment can adopt the existing contact charging technology.

[0068] The support 1 is also provided with an inflation pump and an air extraction pump (not shown in the figure), the inflation pump is provided with an inflation tube, and the air extraction pump is provided with an air extraction tube; the support airbag 222 on the abdominal belt 2 is provided with an air inlet for connecting to the inflation tube, and the negative pressure airbag 401 is provided with an air outlet for connecting to the air extraction tube, and sealing plugs are provided on the air inlet and the air outlet. When the abdominal belt 2 is tied to the patient, the inflation tube is connected to the air inlet on the support airbag 222, and the support airbag 222 is inflated by the inflation pump. When the pressure sensor in the support airbag 222 detects that the inflation pressure reaches a preset value, the inflation is stopped; when the abdominal belt 2 is removed, the air outlet is connected to the negative pressure airbag 401, and the gas in the negative pressure airbag 401 is extracted by the air extraction pump.
