Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a multifunctional drainage device for oral surgery and a method of using the same. Background Art

[0002] Drainage devices in oral surgery are mainly used for postoperative management to help drain the accumulated fluid, blood or exudate in the wound, thereby promoting healing and preventing complications. Blood may accumulate in the wound after surgery, causing hematoma, inflammatory exudate or tissue fluid causing seroma. Drainage devices can drain these fluids in time to avoid local pressure increase, reduce swelling and pain, and prevent accumulated fluid from compressing surrounding tissues (such as nerves and blood vessels) or affecting breathing (such as after major maxillofacial surgery). Effusion is a breeding ground for bacteria, and drainage can reduce the risk of infection. It is suitable for complex situations after tooth extraction (such as impacted wisdom teeth), jaw surgery, and debridement of infectious lesions (such as abscesses).

[0003] Traditional drainage devices have relatively simple functions and can only perform passive drainage, but cannot realize flushing, drug injection and monitoring functions. In addition, they are unstable and have a complex oral environment. Traditional drainage tubes are easily displaced or fall off due to tongue movement or swallowing. They have poor adaptability and cannot adjust the negative pressure according to the shape of the wound, which can easily cause local tissue damage or insufficient drainage. The operation process is cumbersome and requires multiple device replacements, which increases the patient's pain and infection risk. Therefore, a multifunctional oral surgical drainage device and its use method are proposed. The device has multifunctional integration, which can effectively reduce the complexity of operation and combine drainage and flushing through a combined pipeline. The washing and drug administration functions are integrated into a single device, which can avoid the tedious operation of multiple replacements required by traditional devices and reduce the risk of infection. The memory alloy bracket and the adsorption-type fixed head structure, the fixed end can fit the oral anatomical structure, and combined with the micro suction cup for fixation, can effectively prevent displacement due to swallowing or tongue movement. The multi-parameter biosensor monitors pH, temperature and inflammatory markers (such as IL-6) in real time, and abnormal data (such as increased pH and IL-6 surge) can provide early warning of infection or tissue necrosis. The data is transmitted to the terminal in real time, which can facilitate medical staff or monitoring personnel to understand in time. Summary of the Invention

[0004] The present invention provides a multifunctional drainage device for oral surgery and a method of using the same, which solves the problems raised by the above-mentioned existing background technology. It integrates drainage, flushing, drug administration and real-time monitoring functions, which can effectively improve drainage efficiency, reduce repeated operations and reduce the risk of complications.

[0005] The present invention solves the above-mentioned technical problems as follows: a multifunctional drainage device for oral surgery, comprising a drainage device module, a fixing module, and a monitoring module; the drainage device module comprises a negative pressure drainage machine, a drainage pipe, a flushing pipe, a drug administration pipe, a main sleeve, a device base, a drainage liquid collection bottle, a flushing liquid storage cylinder, and a drug storage cylinder; the negative pressure drainage machine is connected with a connecting pipe, the drainage liquid collection bottle is connected with the connecting pipe and the drainage pipe, the drainage liquid collection bottle, the flushing liquid storage cylinder, and the drug storage cylinder are placed at the device base, the main sleeve wraps the drainage pipe, the flushing pipe, and the drug administration pipe, the flushing liquid storage cylinder and the drug storage cylinder are both provided with a liquid extraction pump, the liquid extraction pumps on both sides are both threadedly connected with a one-way valve, the one-way valves on both sides are respectively connected with the flushing pipe and the drug administration pipe, the liquid extraction pump is fixedly connected with a liquid extraction pipe, and the liquid extraction pipes on both sides are respectively introduced into the flushing liquid storage cylinder or the drug storage cylinder;

[0006] The fixing module includes a memory alloy bracket, a micro silicone suction cup, and a multifunctional drainage head. The memory alloy bracket is provided with a load-bearing support leg, the micro silicone suction cup is installed on the load-bearing support leg, and the multifunctional drainage head is installed on the memory alloy bracket. The multifunctional drainage head is provided with a drainage liquid extraction cavity, an irrigating liquid discharge cavity, and a drug delivery cavity. The drainage liquid extraction cavity is evenly provided with drainage holes, the irrigating liquid discharge cavity is evenly provided with a micro atomizing nozzle, and the drug delivery cavity is evenly provided with slow-release micropores.

[0007] The monitoring module includes a biosensor, which is threadedly connected to the multifunctional drainage head. The biosensor includes a pH sensor, a temperature monitor, an electrochemical immunosensor, an analog-to-digital converter, a wireless transmission module, and a micro power supply module.

[0008] The usage includes the following steps:

[0009] S1: Pretreatment: Select the appropriate length of drainage tube, irrigation tube, drug delivery tube and main tube, and the shape of memory alloy stent according to the surgical site, and insert them into the wound after thorough disinfection;

[0010] S2: Fix the device: attach the micro silicone suction cup on the memory alloy bracket to the oral mucosa, fix it by adsorption, connect the drug delivery tube to the one-way valve on the drug storage cylinder, connect the flushing tube to the one-way valve on the flushing liquid storage cylinder, and connect the drainage tube to the drainage liquid collection bottle before use;

[0011] S3: Negative pressure adjustment: Set the initial negative pressure value at the negative pressure drainage machine and adjust the negative pressure according to the amount of fluid accumulation. The drainage fluid in the oral cavity can be drawn into the rinsing fluid through the drainage hole and then transferred to the drainage fluid collection bottle through the drainage pipe for collection;

[0012] S4: Flushing and medication: If the wound site needs to be cleaned, first transfer the flushing fluid (physiological saline or antibacterial solution) to the flushing fluid storage cylinder through the fluid infusion tube for storage, start the liquid pump to transfer the internal flushing fluid to the flushing pipe through the one-way valve, the flushing fluid can be transferred to the flushing fluid discharge cavity through the flushing pipe and sprayed out through the micro-atomizing nozzle, thereby flushing the wound site.

[0013] S5: Monitoring and feedback: The biosensor is equipped with a pH sensor, a temperature monitor, and an electrochemical immunosensor. When oral fluid contacts the surface of the pH sensor, H + Changes in concentration lead to changes in potential difference, which are converted into pH values through electrical signals. The temperature monitor can monitor the temperature inside the oral cavity. After the target inflammatory factor of the electrochemical immunosensor binds to the antibody, the charge distribution on the electrode surface is changed to generate a current or impedance signal. The data of the pH sensor, temperature monitor, and electrochemical immunosensor can be converted into digital signals through an analog-to-digital converter and transmitted through a wireless transmission module.
