Description

Technical Field

[0001] This invention belongs to the technical field of surgical incision rehabilitation equipment, and in particular relates to an intelligent compression device for chest incisions used in the postoperative management of DBS. Background Technology

[0002] Deep brain stimulation (DBS) is a procedure that uses stereotactic techniques to implant stimulating electrodes into specific neural nuclei. The release of electrical pulses modulates these nuclei, thus improving motor symptoms. During DBS surgery, an incision is made in the patient's chest to place the pulse generator for the DBS system. This is because the chest provides sufficient space and minimizes disruption to daily life. Furthermore, the extension wires from the brain electrodes are routed through a subcutaneous tunnel to connect to the pulse generator. The chest incision facilitates the construction of the tunnel and the fixation of the wires, ensuring the stable operation of the entire DBS system. However, poor wound healing after DBS surgery is common due to various reasons, increasing patient suffering and financial burden, and in severe cases, even leading to death. According to literature, spontaneous seizures (SSI) after DBS are one of the most common complications, with an incidence rate of 1%–15%. Currently, there is no dedicated device for managing DBS postoperative brain incisions.

[0003] Currently, the common practice for managing chest incisions after DBS surgery is to wrap two bags of table salt in a dry towel and place them on the incision for pressure. This pressure is applied for 4-6 hours and then removed. While incision compression can reduce bleeding, alleviate edema, promote healing, and stabilize the incision and surrounding tissues, this method has several problems. First, the precision of the compression is severely lacking. Different patients require different levels of pressure after DBS surgery, and this method cannot meet these individual needs. This can easily lead to excessive or insufficient pressure. Excessive pressure can cause secondary damage to the patient's chest incision, greatly affecting the safety and comfort of the patient's recovery. Insufficient pressure, on the other hand, will weaken the incision's healing effect.

[0004] Secondly, during the compression process, table salt is unstable and easily falls off. Furthermore, continuous compression for 4-6 hours may cause local skin discomfort and pain at the incision site. More seriously, excessive compression may also hinder blood circulation at the incision site, thereby negatively affecting the speed and effectiveness of incision healing.

[0005] To address these issues, we propose a smart compression device for chest incisions in the management of DBS postoperative care. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned problems by providing a smart compression device for chest incision management after DBS surgery.

[0019] Compared to existing technologies, the advantages of a smart compression device for chest incisions in post-DBS postoperative management are:

[0020] 1. When using the intelligent chest incision compression device for DBS postoperative management, through the set fixing mechanism, fixing strip, screw, and positioning nut, the positions of the two compression airbags 44 are first adjusted according to the position of the patient's DBS surgery chest incision. After the position of the compression airbags 44 is adjusted, the screw 42 of the thick rubber strip 31 of the compression airbags 44 is passed through the corresponding mounting through hole 21 and positioned by connecting the screw 42 with the positioning nut 43. Then, the fixing strip 1 is fixedly applied to the patient's chest through the fixing mechanism 3. The elasticity of the rubber strip 31 and the extension strip 32 allows the fixing strip 1 to adapt to patients of different body types. Then, the adhesive layer 33 of the extension strip 32 is tightly attached to the patient's back skin to complete the limitation of the position of the compression airbags 44 and prevent the compression airbags 44 from shifting and failing. Then, the triggering mechanism is also attached to the patient's upper lip skin with tape. This mechanism makes the intelligent chest incision compression device have stable operation and improves the reliability of the device.

[0021] 2. Through the established compression mechanism, air pump, triggering mechanism, air intake filtration mechanism, and air supply mechanism, the air pump first starts to deliver sufficient air to the air supply area. During the air pump's suction process, the air is purified by the air intake filtration mechanism to remove impurities and microorganisms, ensuring clean air entering the air supply area. Then, the triggering mechanism intermittently controls the air supply mechanism based on the humidity changes in the patient's respiratory airflow. This allows the compression mechanism to manage the compression of the chest incision intermittently with the patient's breathing. This intermittent compression of the chest incision in sync with the patient's breathing has several advantages. Firstly, during inhalation, the expansion of the lungs generates an outward pulling force on the chest incision. At this time, the chest incision is intelligently compressed during inhalation... The device can apply pressure to effectively counteract this traction force. Secondly, intermittent compression can simulate normal physiological pressure changes. The pressure disappears during exhalation, allowing local tissues to receive temporary blood perfusion recovery during this period. In addition, compared to continuous compression, intermittent compression can reduce patient discomfort to some extent. This mechanism not only enables the device to intermittently compress the chest incision according to the patient's breathing rate, but also has the function of safely adjusting the compression force to meet the patient's individual needs. It can also effectively improve the intelligence of the device, enhance the device's compression effect on the patient's chest incision, improve the patient's chest incision recovery, and improve the reliability of the device's use.

[0022] 3. Through the incision drying mechanism, electric heating element, semiconductor cooling chip, and temperature sensor, clean air discharged from the compression mechanism enters the incision drying mechanism. The flowing clean air is used to dry the patient's chest incision, preventing excessive moisture and bacterial infection. The electric heating element, semiconductor cooling chip, and temperature sensor can adjust the temperature of the clean air input to the compression mechanism according to the ambient temperature, reducing the temperature of the clean air in the air supply area to within the range of 36-37 degrees Celsius. This ensures 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 excessive temperature difference at the patient's chest incision. Moreover, the suitable temperature can maintain the cell activity at the patient's chest incision, promoting rapid incision healing. This mechanism enables the device to keep the patient's chest incision warm and dry, effectively preventing bacterial infection caused by moisture at the patient's chest incision, effectively promoting incision healing, and improving the reliability of the device.

[0023] 4. Through the set display screen, the PLC controller can digitize the values ​​detected by the pressure sensor, air pressure sensor, temperature sensor and miniature humidity sensor in the intelligent chest incision compression device, and display them directly on the display screen. In addition, the display screen can also display the safety compression force F1 and ambient humidity P1 preset in the PLC controller by the control panel, so as to facilitate the use of the device by medical staff. This mechanism makes the device have the ability to make the compression pressure visible, improves the safety of the device and improves the reliability of the device. Attached Figure Description

A pressure sensor 46 is fixedly connected to the outer wall of the thick rubber plate 41 at the elastic arc-shaped strip. Arc-shaped tubes 47 are fixedly connected to the side ends of the two compression airbags 44. The tube wall of the arc-shaped tube 47 is fixedly connected to an air inlet pipe 48 and an exhaust solenoid valve 49.

[0033] The exhaust solenoid valve 49 is fixedly connected to the incision drying mechanism 5 at its outlet end. The incision drying mechanism 5 includes an air guide tube 51 and an air intake tube 52. A rubber ring 53 is movably sleeved at one end of the air guide tube 51 and the air intake tube 52. Two connecting pieces 54 for tape adhesion are fixedly connected to the outer wall of the rubber ring 53. The outer walls of the two vertically arranged connecting pieces 54 are fixedly connected to a connecting rope 55. This mechanism enables the device to dry the patient's chest incision, effectively preventing bacterial infection caused by moisture in the patient's chest incision, effectively promoting incision healing, and improving the reliability of the device.

[0034] Two partition plates 6 are fixedly connected to the inner wall of the air supply box 2. The two partition plates 6 divide the internal cavity of the air supply box 2 into an air supply area 10, an air intake area 11 and an installation area 12.

A PLC controller 15 is fixedly connected to the inner wall of the air supply box 2 in the installation area 12. A trigger mechanism 7 is electrically connected to the input terminal of the PLC controller 15. The trigger mechanism 7 includes a connecting wire 71 electrically connected to the input terminal of the PLC controller 15. The input terminal of the connecting wire 71 passes through the outer wall of the air supply box 2 and is wired to a miniature humidity sensor 72.

An adhesive groove 75 for tape bonding is opened on the outer wall of the lip strip 74.

[0035] An air pump 16 is fixedly connected to the outer wall of one of the partition plates 6. The outlet end of the air pump 16 passes through the partition plate 6 and is fixedly connected to an exhaust check valve 17. The exhaust check valve 17 is located inside the air supply area 10. A threaded ring 18 is fixedly connected to the outer wall of the air intake area 11 of the air supply box 2. An air intake filter mechanism 8 is threadedly connected to the outer wall of the threaded ring 18.

The top of one of the meltblown cloth filter layers 83 is connected to the sponge filter block 85. When the outside air passes through the air intake filter mechanism 8, it is filtered and purified multiple times by the sponge filter block 85, the meltblown cloth filter layer 83 and the activated carbon particle layer 84, which removes a large number of microorganisms and impurities in the air and ensures that the air will not cause incision infection when passing through the patient's chest incision.

[0036] An air supply box 2 is fixedly connected to an air supply mechanism 9 on the outer wall of the air supply area 10. The air supply mechanism 9 includes an intake solenoid valve 91, the intake end of which is fixedly connected to the outer wall of the air supply box 2 in the air intake area 11.

A temperature sensor 97 is fixedly connected to the outer wall of the air supply box 2. This mechanism can realize intermittent automatic compression of the patient's chest incision, and the device is reliable in use.

[0037] Pressure sensor 46, air pressure sensor 92, and temperature sensor 97 are all electrically connected to the input terminal of PLC controller 15 via wires. Miniature humidity sensor 72 is electrically connected to the input terminal of PLC controller 15 via connecting wire 71. Exhaust solenoid valve 49, intake solenoid valve 91, electric heating tube 93, semiconductor cooling chip 95, display screen 13, and air pump 16 are all electrically connected to the output terminal of PLC controller 15 via wires. The above electrical connections and power supply equipment are all prior art and will not be described in detail here.

[0038] The operating principle of this invention is described as follows: When a patient requires compression management of the chest incision after DBS surgery, the positions of the two compression airbags 44 are first adjusted according to the location of the patient's DBS chest incision. After the compression airbags 44 are adjusted, the screw 42 of the compression airbag 44 located on the thick rubber strip 31 is passed through the corresponding mounting through hole 21, and the screw 42 is positioned by connecting the positioning nut 43. Then, the fixing cloth strip 1 is fixedly applied to the patient's chest by the fixing mechanism 3. The elasticity of the rubber strip 31 and the extension strip 32 allows the fixing cloth strip 1 to adapt to different... For patients of this size, the adhesive layer 33 of the extension strip 32 is then tightly attached to the patient's back skin to define the position of the compression airbag 44 and prevent the compression airbag 44 from shifting or failing. At the same time, the lip strip 74 of the triggering mechanism 7 is placed on the skin of the patient's upper lip. Then, the miniature 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 the stable positioning of the miniature humidity sensor 72. This mechanism enables the intelligent compression device for chest incisions to have stable operation and improves the reliability of the device.

[0039] Following this, medical staff, based on the patient's individual condition, preset the safety pressure F1 of the compression airbag 44 in the PLC controller 15 via the control panel 14, and detected the ambient humidity via the miniature humidity sensor 72, also preset the ambient humidity P1 in the PLC controller 15. Specifically, to ensure patient recovery, the relative humidity in hospital wards should ideally be between 40% and 60%. The patient's exhaled air is nearly saturated, containing a high water vapor content. This is because when air is inhaled, the glands in the respiratory tract secrete mucus to humidify and warm the inhaled air, adapting it to the needs of gas exchange in the lungs. After gas exchange, the exhaled air contains moisture that has seeped from the respiratory tract mucosa and alveolar tissue, thus humidifying the air. The humidity is relatively high, far exceeding that of the ward environment. Therefore, the triggering mechanism 7 can reliably use the humidity of the gas before and after breathing to control the intermittent compression of the chest incision. In addition, if the patient is robust and recovers well after DBS surgery, the safe compression force F1 of the compression cuff 44 can be set to a larger value to avoid the compression effect being poor due to insufficient compression force of the compression cuff 44. If the patient is thin and recovers poorly after DBS surgery, and cannot withstand the large compression force of the compression cuff 44, the safe compression force F1 of the compression cuff 44 can be set to a lower value to avoid the secondary injury to the chest incision caused by excessive compression force of the compression cuff 44. The individual needs of different patients can be met by adjusting the compression force of the compression cuff 44.

[0040] Then, the PLC controller 15 controls the air pump 16 to start. The air pump 16 draws in 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 multiple times by the sponge filter block 85, the meltblown cloth filter layer 83, and the activated carbon granule layer 84, removing a large number of microorganisms and impurities from the air. The clean air then enters the air supply area 10 of the air supply box 2 through the exhaust one-way valve 17 for temporary storage. At the same time, the air pressure sensor 92 of the air supply area 10 monitors 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 sensor 92 detects that the air pressure value in the air supply area 10 reaches the preset alarm air pressure threshold of the PLC controller 15, the PLC controller 15 controls the air pump 16 to stop pumping air according to the electrical signal. At the same time, if the air pressure detected by the air pressure sensor 92 is lower than the alarm air pressure threshold, the PLC controller 15 automatically controls the air pump 16 to pump air to supplement the air supply area 10, so that there is a sufficient supply of clean air in the air supply box 2.

[0041] When the patient inhales, air from outside is drawn in through the nostrils. The humidity value detected by the miniature humidity sensor 72 does not exceed the preset ambient humidity P1 of the PLC controller 15. Then, the PLC controller 15 energizes and opens the intake solenoid valve 91, allowing compressed air in the air supply zone 10 to enter the compression airbags 44 through the open intake solenoid valve 91, intake pipe 48, and arc-shaped pipe 47. The two compression airbags 44 inflate to compress the areas on both sides of the patient's chest incision. During the inflation of the compression airbags 44, the elastic arc-shaped steel strip 45 is pushed to compress the detection end of the pressure sensor 46. As the pressure sensor 46 is compressed, it sends the real-time force as an electrical signal to the PLC controller 15. If the pressure sensor 46... When the pressure of the pressure bladder 44 reaches the preset safe pressure F1 of the PLC controller 15, the PLC controller 15 immediately controls the intake solenoid valve 91 to close based on the signal fed back by the pressure sensor 46. This stops the pressure bladder 44 from continuing to inflate and causing excessive pressure, thus preventing secondary damage to the patient's chest due to excessive pressure. During exhalation, the humidity of the air expelled from the patient's nostrils is high, causing the humidity detected by the miniature humidity sensor 72 located on the outside of the patient's nostrils to far exceed the preset ambient humidity P1 of the PLC controller 15. The miniature 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 based on this electrical signal. When 49 is powered on and opened, the clean air inside the compression bag 44 is forced out by the opposing compression of the fixing mechanism 3 and the fixing cloth strip 1, and enters the incision drying mechanism 5 through the arc-shaped tube 47 and the exhaust solenoid valve 49. This intermittent compression of the chest incision with the patient's breathing has several benefits. First, during inhalation, the expansion of the lungs will exert an outward pulling force on the chest incision. At this time, by applying pressure through the intelligent chest compression device during inhalation, this pulling force can be effectively counteracted, like setting up a dynamic "protective net" at the incision, preventing the incision from tearing due to excessive lung expansion. Second, intermittent compression can simulate normal physiological pressure changes. When exhalation, the compression disappears, allowing the local tissue to receive temporary blood perfusion recovery during this period. Normal blood circulation is crucial for wound healing. It delivers oxygen and nutrients, such as proteins and glucose, to the wound while removing metabolic waste products like carbon dioxide and lactic acid. This alternating compression helps prevent prolonged pressure on local tissues, which can lead to circulatory problems, ischemia, and hypoxia, thus promoting proper wound healing. Furthermore, compared to continuous compression, intermittent compression can alleviate patient discomfort. Continuous pressure on the chest can cause persistent pain and tightness, while intermittent compression allows for a brief relaxation period during exhalation, providing greater comfort and facilitating better cooperation with postoperative care and recovery.This device not only provides intermittent compression of the chest incision in accordance with the patient's respiratory rate, but also allows for personalized adjustment of the compression force to meet individual patient needs. It effectively enhances the device's intelligence, improves the compression effect on the chest incision, promotes patient recovery, and increases the device's reliability.

[0042] The incision drying mechanism 5 is stably positioned on both sides of the incision while the compression airbag 44 is fixed. Specifically, the connecting piece 54 is attached to the patient's chest skin with tape. Then, the connecting piece 54 uses rubber rings 53 to limit the air delivery tube 51 and the air drainage tube 52 to both sides of the patient's chest incision. The air outlet of the air drainage tube 52 is located on the outside of the fixing strip 1, and the air outlet of the air delivery tube 51 and the air inlet of the air drainage tube 52 can be located on the inside of the patient's chest incision care gauze. When the air delivery tube 51 discharges clean air from the arc-shaped tube 47 into the chest incision, the flow of clean air can prevent the patient's chest incision from becoming too moist and breeding bacteria. Afterward, the air at the incision is discharged through the air drainage tube 52. The flow of air can ensure that the patient's chest is dry. Moreover, the temperature of the clean air in the air supply area 10 that is about to enter the compression airbag 44 can be adjusted according to the ambient temperature. The temperature sensor 97 can detect the ambient temperature and send the detected temperature value to the PLC controller in the form of an electrical signal. 15. If the ambient temperature is lower than the preset body temperature threshold of the PLC controller 15, the PLC controller 15 controls the electric heating tube 93 to heat up. The electric heating tube 93 raises the temperature of the clean air in the air supply area 10 to the range of 36-37 degrees Celsius through the metal heat dissipation mesh 94. If the ambient temperature exceeds the preset body temperature threshold of the PLC controller 15, the PLC controller 15 controls the semiconductor cooling chip 95 to start. The semiconductor cooling chip 95 lowers the temperature of the clean air in the air supply area 10 to the range of 36-37 degrees Celsius through the metal heat dissipation mesh 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. Moreover, the appropriate temperature can also ensure the cell activity at the patient's chest incision, promoting rapid incision healing. This mechanism enables the device to keep the patient's chest incision warm and dry, effectively preventing bacterial infection caused by moisture at the patient's chest incision, effectively promoting incision healing, and improving the reliability of the device.
