Description

Technical Field

[0001] The present invention belongs to the technical field of surgical incision rehabilitation equipment, and in particular relates to a chest incision intelligent compression device for DBS postoperative management. Background Art

[0002] Deep brain stimulation (DBS) is a procedure that uses stereotactic technology to implant stimulating electrodes into specific neural nuclei, and releases electrical pulses to regulate the neural nuclei to produce a therapeutic effect and improve the patient's motor symptoms. During the DBS operation, an incision needs to be made in the patient's chest to place the pulse generator for the DBS system. This is because the chest has enough space to accommodate it and it interferes less with daily life. At the same time, the extension wires from the brain electrodes must be connected to the pulse generator through a subcutaneous tunnel. When constructing the tunnel and fixing the wires, the chest incision is convenient for operation, thereby ensuring the stable operation of the entire DBS system. However, poor incision healing due to various reasons after DBS surgery often occurs, which not only increases the patient's pain and economic burden, but can also cause death in severe cases. According to literature reports, SSI after DBS surgery is one of the most common complications of the operation, with an incidence of 1% to 15%. There is no dedicated brain incision management device after DBS surgery in clinical practice.

[0003] At present, the management of chest incision after DBS surgery usually adopts the method of wrapping two bags of edible salt with a dry towel and placing them on the incision for compression, which is removed after 4-6 hours of compression. The compression of the incision itself can reduce bleeding, reduce edema, promote healing, and fix the incision and surrounding tissues. However, there are many problems in this compression process. First, the accuracy of compression is seriously insufficient. The degree of compression required for the chest incision after DBS surgery varies from patient to patient, and this method cannot meet such personalized needs. This can easily lead to excessive or insufficient pressure. When the pressure is too high, it will cause secondary damage to the patient's chest incision after surgery, greatly affecting the safety and comfort of the patient's recovery. When the pressure is too low, it will weaken the effect of incision rehabilitation.

[0004] Secondly, during the compression process, table salt as a compression material has poor stability and is easy to fall off. In addition, continuous compression for 4-6 hours may cause local skin discomfort and pain at the incision. What is more serious is that excessive compression may also hinder the blood circulation of the incision, thereby having a negative impact on the speed and effect of incision healing.

[0005] To this end, we proposed an intelligent compression device for chest incision for postoperative management of DBS to solve the above problems. Summary of the invention

[0019] Compared with existing technologies, the advantages of a chest incision intelligent compression device for DBS postoperative management are:

[0020] 1. By means of the provided fixing mechanism, fixing cloth strip, screw and positioning nut, when the chest incision intelligent compression device for DBS postoperative management is used, firstly, the positions of the two compression airbags 44 are adjusted according to the position of the chest incision of the patient's DBS surgery. After the position of the compression airbag 44 is adjusted, the screw 42 of the compression airbag 44 located at the thick rubber strip 31 is passed through the corresponding mounting through hole 21, and the screw 42 is connected by the positioning nut 43 for positioning. Then, the fixing cloth strip 1 is fixedly applied to the patient's chest by the fixing mechanism 3, wherein the elasticity of the rubber strip 31 and the extension strip 32 can make the fixing cloth strip 1 adapt to patients of different body shapes. Then, the adhesive layer 33 of the extension strip 32 is closely attached to the patient's back skin to complete the position limitation of the compression airbag 44, and the compression airbag 44 will not fail to move. Then, the trigger mechanism is also attached to the patient's upper lip skin by tape. This mechanism enables the chest incision intelligent compression device to have the ability of stable use and improves the reliability of the device.

[0021] 2. Through the compression mechanism, vacuum pump, trigger mechanism, air intake filter mechanism and air supply mechanism, the vacuum pump is started to deliver sufficient air to the air supply area, and the air is purified by the air intake filter mechanism during the suction process of the vacuum pump to remove impurities and microorganisms in the air, so as to ensure the cleanliness of the air entering the air supply area. Then, the trigger mechanism intermittently controls the air supply of the air supply mechanism according to the humidity change of the patient's respiratory airflow, and enables the compression mechanism to compress the chest incision intermittently with the patient's breathing. This intermittent compression of the chest incision with the patient's breathing has many advantages. First, when inhaling, the expansion of the lungs will produce an outward pulling force on the chest incision. At this time, the chest is intelligently compressed during inhalation. The compression device can be used to apply pressure, which can effectively counteract this pulling force. Secondly, intermittent compression can simulate normal physiological pressure changes. The compression disappears during exhalation, allowing local tissues to obtain a brief blood perfusion recovery during this period. In addition, compared with continuous compression, intermittent compression can alleviate the patient's discomfort to a certain extent. This mechanism enables the device to not only have the function of intermittently compressing the chest incision with the patient's breathing frequency, but also has the function of safe compression force to meet the patient's personalized adjustment, and can effectively improve the intelligence of the device, as well as improve the effect of the device on the patient's chest incision compression, improve the effect of the patient's chest incision rehabilitation, and improve the reliability of the device.

[0022] 3. Through the incision drying mechanism, electric heating tube, semiconductor refrigeration sheet and temperature sensor, the clean air discharged by the compression mechanism enters the incision drying mechanism, and the flowing clean air flow is used to dry the patient's chest incision to prevent excessive moisture and bacterial infection at the incision. The electric heating tube, semiconductor refrigeration sheet and temperature sensor can adjust the temperature of the clean air input into the compression mechanism according to the external ambient temperature, and reduce the clean air temperature in the air supply area to within the range of 36-37 degrees Celsius, to ensure that the temperature of the clean air delivered to the patient's incision is not much different from the body temperature, to avoid discomfort caused by temperature imbalance at the patient's chest incision due to excessive temperature difference, and the appropriate temperature can also ensure the cell activity at the patient's chest incision, and promote rapid healing of the incision. This mechanism enables the device to have the function of keeping the patient's chest incision warm and drying, which can effectively prevent the patient's chest incision from breeding bacterial infection due to moisture, effectively promote the healing effect of the incision, and improve the reliability of the device.

[0023] 4. Through the setting of the display screen, the PLC controller can digitize the values ​​detected by the pressure sensor, air pressure sensor, temperature sensor and micro humidity sensor in the chest incision intelligent compression device, and directly display them on the display screen. The display screen can also display the safe compression force F1 and ambient humidity P1 preset by the control panel in the PLC controller, so that medical staff can use the device conveniently. This mechanism enables the device to have the ability to visualize the compression pressure, improve the safety of the device, and improve the reliability of the device.

[0036] The outer wall of the air supply box 2 located in the air supply area 10 is fixedly connected to an air supply mechanism 9, and the air supply mechanism 9 includes an air intake solenoid valve 91.

[0037] The pressure sensor 46, the air pressure sensor 92 and the temperature sensor 97 are all electrically connected to the input end of the PLC controller 15 through wires, the micro humidity sensor 72 is electrically connected to the input end of the PLC controller 15 through the connecting wire 71, the exhaust solenoid valve 49, the intake solenoid valve 91, the electric heating tube 93, the semiconductor refrigeration plate 95, the display screen 13 and the vacuum pump 16 are all electrically connected to the output end of the PLC controller 15 through wires. The above-mentioned electrical connections and power-on devices are all existing technologies and will not be repeated here.

[0038] The operating principle of the present invention is described as follows: when a patient needs to compress the chest incision after DBS surgery, first adjust the positions of the two compression airbags 44 according to the position of the chest incision of the patient's DBS surgery. After the position of the compression airbags 44 is adjusted, the screw 42 of the compression airbag 44 located at the thick rubber strip 31 passes through the corresponding installation through hole 21, and is connected to the screw 42 through the positioning nut 43 for positioning, and then the fixing cloth strip 1 is fixedly applied to the patient's chest through the fixing mechanism 3, wherein the elasticity of the rubber strip 31 and the extension strip 32 can enable the fixing cloth strip 1 to adapt to different The patient has a certain body shape, and then the adhesive layer 33 of the extension strip 32 is closely attached to the patient's back skin to complete the definition of the position of the compression airbag 44, and the compression airbag 44 will not fail to move. At the same time, the lip strip 74 of the trigger mechanism 7 is arranged on the skin of the patient's upper lip, and then the micro humidity sensor 72 is aligned with the outside of the patient's nostrils. Finally, the tape is passed through the adhesive groove 75 and attached to the patient's upper lip skin to ensure that the micro humidity sensor 72 is stably positioned. This mechanism enables the chest incision intelligent compression device to have the ability to be used stably, and improves the reliability of the device.

[0039] Then, the medical staff presets the safety compression force F1 of the compression airbag 44 in the PLC controller 15 through the control panel 14 according to the patient's individual situation, detects the humidity of the environment through the micro humidity sensor 72, and presets the environmental humidity P1 in the PLC controller 15. Specifically, in order to ensure the recovery of patients, the relative humidity of the hospital ward should be in the range of 40%-60%, and the gas exhaled by the patient is close to saturation, with a high water vapor content. This is because when air is inhaled, the glands of the respiratory mucosa secrete mucus to humidify and heat the inhaled air to adapt it to the needs of lung gas exchange. After gas exchange, the exhaled gas contains moisture exuded from the respiratory mucosa and alveolar tissue, with the moisture in the form of humidified air. The humidity is relatively high, and this humidity far exceeds the humidity of the ward environment. Therefore, the trigger mechanism 7 can reliably use the humidity of the gas before and after breathing to realize the control of intermittent compression of the chest incision. In addition, if the patient is strong and has recovered well after DBS surgery, the value of the safety compression force F1 of the compression airbag 44 is set to be relatively large to avoid the situation where the compression force of the compression airbag 44 is small and the compression effect is poor. If the patient is thin and has recovered poorly after DBS surgery, and the patient cannot withstand the large compression force of the compression airbag 44, the value of the safety compression force F1 of the compression airbag 44 is set to be reduced accordingly to avoid the situation where the compression force of the compression airbag 44 is too large and causes secondary injury to the patient's chest incision. The personalized needs of different patients can be met by adjusting the compression force of the compression airbag 44.

[0040] After that, the PLC controller 15 controls the vacuum pump 16 to start, and the vacuum pump 16 sucks the outside air through the threaded ring 18 and the air intake filter mechanism 8. When the outside air passes through the air intake filter mechanism 8, it is filtered and purified for many times by the sponge filter block 85, the melt-blown filter layer 83 and the activated carbon particle layer 84, filtering out a large number of microorganisms and impurities in the air, so that the clean air enters the air supply area 10 of the air supply box 2 through the exhaust check valve 17 for temporary storage. At the same time, the air pressure sensor 92 of the air supply area 10 detects the air pressure of the air supply area 10 in real time. The air pressure sensor 92 sends the detected air pressure value to the PLC controller 15 in the form of an electrical signal. If the air pressure value of the air supply area 10 detected by the air pressure sensor 92 reaches the warning air pressure threshold preset by the PLC controller 15, the PLC controller 15 controls the air pump 16 to suspend air extraction according to the electrical signal. At the same time, when the air pressure detected by the air pressure sensor 92 is lower than the warning air pressure threshold, the PLC controller 15 automatically controls the air pump 16 to extract air to supplement the air supply area 10, so that there is sufficient clean air supply in the air supply box 2.

[0041] After that, when the patient inhales, the patient inhales external air through his nostrils. The air humidity value detected by the micro humidity sensor 72 does not exceed the ambient humidity P1 preset by the PLC controller 15. Then the PLC controller 15 controls the air intake solenoid valve 91 to be energized and opened, so that the compressed air in the air supply area 10 enters the compression airbag 44 through the opened air intake solenoid valve 91, the air intake pipe 48 and the arc tube 47. The two compression airbags 44 inflate to compress the areas on both sides of the patient's chest incision, and during the inflation of the compression airbags 44, the elastic arc-shaped steel bar 45 is pushed to squeeze the detection end of the pressure sensor 46. As the pressure sensor 46 is pressurized, the pressure sensor 46 sends the real-time force in the form of an electrical signal to the PLC controller 15. If the pressure sensor 46 When the detected compression force of the compression airbag 44 reaches the safety compression force F1 preset by the PLC controller 15, the PLC controller 15 immediately controls the closing of the air intake solenoid valve 91 according to the signal fed back by the pressure sensor 46, stops the compression airbag 44 from continuing to expand and causing excessive compression force, thereby avoiding secondary injury to the patient's chest due to excessive compression force. When the patient exhales, the humidity of the gas discharged from the patient's nostrils is relatively high, so that the exhaled humidity detected by the micro humidity sensor 72 located on the outside of the patient's nostrils far exceeds the ambient humidity P1 preset by the PLC controller 15, and the micro humidity sensor 72 transmits the detected humidity value to the PLC controller 15 in the form of an electrical signal, and the PLC controller 15 controls the exhaust solenoid valve according to the electrical signal. 49 is powered on and turned on. At this time, the clean air inside the compression airbag 44 is squeezed out by the fixing mechanism 3 and the fixing cloth strip 1 in the opposite direction and enters the incision drying mechanism 5 through the arc tube 47 and the exhaust solenoid valve 49. This intermittent compression of the chest incision as the patient breathes has many advantages. First, when inhaling, the expansion of the lungs will produce an outward pulling force on the chest incision. At this time, by pressurizing the chest intelligent compression device during inhalation, this pulling force can be effectively resisted, just like setting a dynamic "protective net" at the incision to avoid incision rupture due to excessive expansion of the lungs. Secondly, intermittent compression can simulate normal physiological pressure changes. The compression disappears during exhalation, which can allow local tissues to obtain a short period of blood perfusion recovery during this period. Normal blood circulation is essential for wound healing. It can provide the wound with oxygen and nutrients, such as protein and glucose, while taking away metabolic waste, such as carbon dioxide and lactic acid. This compression method, similar to "loose and tight", helps prevent long-term compression of local tissues and cause blood circulation disorders, avoid tissue ischemia and hypoxia, and promote good wound healing. In addition, compared with continuous compression, intermittent compression can alleviate the patient's discomfort to a certain extent. If the chest is compressed all the time, the patient may feel continuous pain and stuffiness, while intermittent compression allows the chest to have a short relaxation period when exhaling, and the patient will feel relatively comfortable, which is conducive to the patient's better cooperation with postoperative care and recovery process.This mechanism enables the device to not only intermittently compress the chest incision according to the patient's breathing frequency, but also has the function of safely adjusting the pressure to meet the patient's personalized adjustment, and can effectively improve the intelligence of the device, improve the effect of the device on the patient's chest incision compression, improve the effect of the patient's chest incision rehabilitation, and improve the reliability of the device.

[0042] When the compression airbag 44 is fixed, the incision drying mechanism 5 is also stably arranged at both sides of the incision. Specifically, the connecting piece 54 is attached to the patient's chest skin by tape, and then the connecting piece 54 limits the airway tube 51 and the air induction tube 52 at both sides of the patient's chest incision through the rubber ring 53, wherein the air outlet of the air induction tube 52 is arranged on the outside of the fixed cloth strip 1, and the air outlet end of the airway tube 51 and the air inlet end of the airway tube 52 can be arranged on the inner side of the patient's chest incision nursing gauze. When the airway tube 51 discharges the clean air in the arc tube 47 into the chest incision, the flow of clean air can prevent the patient's chest incision from being too humid and breeding bacteria. After that, the air at the incision is discharged through the air induction tube 52. The flowing air can ensure that the patient's chest is dry, and the temperature of the clean air in the air supply area 10 to be entered into the compression airbag 44 can be adjusted according to the external environment temperature. The temperature sensor 97 can detect the external environment temperature, and the temperature sensor 97 can send the detected temperature value to the PLC controller in the form of an electrical signal. 15. If the outside temperature is lower than the body temperature threshold preset by the PLC controller 15, the PLC controller 15 controls the electric heating tube 93 to generate heat, and the electric heating tube 93 raises the clean air temperature in the air supply area 10 to the range of 36-37 degrees Celsius through the metal heat dissipation grid 94. If the outside temperature exceeds the body temperature threshold preset by the PLC controller 15, the PLC controller 15 controls the semiconductor refrigeration plate 95 to start, and the semiconductor refrigeration plate 95 lowers the clean air temperature in the air supply area 10 to the range of 36-37 degrees Celsius through the metal heat dissipation grid 94, ensuring that the temperature of the clean air delivered to the patient's incision is not much different from the body temperature, avoiding discomfort caused by temperature imbalance at the patient's chest incision due to excessive temperature difference, and the appropriate temperature can also ensure the cell activity at the patient's chest incision, and promote rapid healing of the incision. This mechanism enables the device to have the function of keeping the patient's chest incision warm and dry, which can effectively avoid the situation where the patient's chest incision breeds bacterial infection due to moisture, effectively promote the healing effect of the incision, and improve the reliability of the use of the device.
