Description

Technical Field

[0001] This invention belongs to the technical field of drainage devices, and in particular relates to a multifunctional drainage device for a large pool that measures pressure and temperature, and prevents slippage and waist dislocation. Background Technology

[0002] Continuous drainage via lumbar cistern catheterization is a routine invasive procedure in neurosurgery, widely used in aneurysm hemorrhage, traumatic brain injury, and hypertensive intracerebral hemorrhage. While the drainage method is simple and easy to perform, current commercially available products have limitations in clinical application. Problems such as difficulty in catheter placement, catheter slippage, and even the possibility of the catheter breaking off and remaining in the patient's subarachnoid space may occur during clinical procedures.

[0003] The existing technology still has the following technical problems: In clinical applications, the lumbar cistern catheter is a straight-tipped drainage tube, which does not have the function of preventing slippage and is easy to slip out of the body; When performing lumbar cistern puncture, it is necessary to temporarily measure intracranial pressure. In clinical applications, intracranial pressure is measured by transcranial implantation of a pressure measuring probe, but transcranial pressure measurement surgery is complex, technically difficult, and may cause intracranial hemorrhage and intracranial infection. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional drainage device for pressure and temperature measurement, anti-slip and waist dislocation in a large pool, to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A multi-functional drainage device for pressure and temperature measurement, preventing slippage and lumbar dislocation, is provided, including a drainage tube. The proximal end of the drainage tube is provided with a quick-connect interface for connecting a drainage bag. The drainage tube is provided with a fixing component, a temperature monitoring device, and a pressure monitoring device. The pressure monitoring device includes a pressure-measuring balloon located at the distal end of the drainage tube. The pressure-measuring balloon communicates with a pressure sensor located at the proximal end of the drainage tube through a pipe located within the side wall of the drainage tube. The temperature monitoring device includes a temperature sensor located at the distal end of the drainage tube. The temperature sensor and the pressure sensor are respectively connected to an Internet of Things (IoT) communication module located at the proximal end of the drainage tube via signal lines. The fixing component includes a fixing airbag located on the outer periphery of the distal end of the drainage tube. An inflation tube is provided within the side wall of the drainage tube. The distal end of the inflation tube communicates with the fixing airbag, and the proximal end passes through the side wall of the drainage tube to the proximal end of the drainage tube and communicates with an air source.

[0006] Preferably, the proximal end of the drainage tube is provided with a branch handle, the inflation tube of the pressure measuring balloon and the signal line pass through the side wall of the drainage tube in the branch handle and are connected to the control box, and the inflation tube passes through the control box and is connected to an external air source.

[0007] Preferably, the control box is provided with a touch screen, which is used to display the temperature inside the pipeline monitored by the temperature monitoring device and the pressure inside the pipeline monitored by the pressure monitoring device.

[0008] Preferably, the quick interface is equipped with an electromagnetic switching valve and a one-way valve.

[0009] Preferably, the outer wall of the drainage tube is provided with an antibacterial coating.

[0010] The beneficial effects are as follows: This application can continuously measure the core and central nervous system temperature and monitor intracranial pressure using temperature and pressure monitoring devices installed on the lumbar drainage tube. Furthermore, a fixing component secures the distal end of the drainage tube within the lumbar cistern to prevent slippage or breakage within the patient. Since the tube is not transcranial, complications such as intracranial hemorrhage and intracranial infection are avoided, and operation and nursing care are simplified. Attached Figure Description

[0013] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0014] like Figure 1 As shown, the present invention provides a multi-functional drainage device for pressure and temperature measurement and anti-slip waist dislocation in a large pool, including a drainage tube 3. The proximal end of the drainage tube 3 is provided with a quick interface 302 connected to the drainage bag 2. The drainage tube 3 is provided with a fixing component, a temperature monitoring device and a pressure monitoring device.

[0015] The pressure monitoring device includes a pressure-measuring balloon 305 located at the distal end of the drainage tube. The pressure-measuring balloon 305 communicates with an inflation pressure-measuring module 101 located at the proximal end of the drainage tube via a pipe located in the side wall of the drainage tube. The temperature monitoring device includes a temperature sensor 104 located at the distal end of the drainage tube.

[0016] In one specific embodiment, the temperature monitoring device includes a temperature sensor 104, which continuously and indirectly measures the temperature of the human core and central nervous system by directly monitoring the temperature of the drainage fluid in the lumbar cistern. The temperature sensor 104 is connected to a temperature measuring module 105 located near the end of the drainage tube 3 via a signal line 107.

[0017] The pressure monitoring device is a diaphragm-semiconductor pressure sensor, similar in structure to the Spiegelberg intracranial pressure monitor from Germany. Referring to existing technology, its airbag system consists of a hollow plastic body connected to the pressure sensor via tubing. The pressure sensor, electronic hardware, and airbag inflation device are integrated into the ICP monitor. In this application, the tubing and pressure sensor are used to measure intracranial pressure via the lumbar cistern. The pressure sensor and airbag inflation device are integrated into the inflation pressure measurement module 101 and arranged together with the electronic hardware in the control box 1. After the airbag inflation device of the inflation pressure measurement module 101 inflates the pressure measurement balloon 305 through the inflation tube 108 connected to the balloon 305, the pressure change caused by the change in intracranial pressure and the corresponding air volume in the balloon 305 is transmitted through the tubing to the pressure sensor probe of the inflation pressure measurement module 101. The pressure sensor converts this into an electrical signal, and the intracranial pressure (ICP) is displayed on the touch screen 102. The airbag inflation device of the inflation and pressure testing module 101 is replaced with a balloon liquid filling device using a liquid-filled pressure testing balloon 305.

[0018] The fixing component includes a fixing airbag 301 disposed on the outer periphery of the distal end of the drainage tube 3. An inflation tube 108 connected to the fixing airbag 301 is provided in the side wall of the drainage tube 3. The distal end of the inflation tube 108 is connected to the fixing airbag 301, and the proximal end is led out from the proximal side wall of the drainage tube 3 and is provided with an inflation port 103. The inflation port 103 is connected to an external air source and the air supply and de-inflation are controlled by the air source.

[0019] The proximal end of the drainage tube 3 is provided with a branch handle 304. The inflation tube 108 of the pressure measuring balloon 305 and the signal line 107 run parallel inside the side wall of the drainage tube 3 to the branch handle 304, and then pass out from the side wall of the drainage tube 3 and are respectively connected to the inflation pressure measuring module 101 and the temperature measuring module 105 in the control box 1. Then, the temperature measuring module 105 and the inflation pressure measuring module 101 convert the monitored temperature signal and pressure signal into electrical signals and connect them to the Internet of Things communication module 106 located at the proximal end of the drainage tube 3 through the signal line.

[0020] In one specific embodiment, the inner wall of the fixation balloon 301 is fixed to the outer periphery of the distal end of the drainage tube 3. Inflation causes the fixation balloon 301 to expand and become lodged within the patient's lumbar cistern, preventing the drainage tube 3 from slipping out or breaking off and remaining in the patient's body. The pressure-measuring balloon 305 is located distal to the drainage tube 3, further forward of the fixation balloon 301, and spaced apart by a distance. The inflated size of the pressure-measuring balloon 305 is slightly smaller than the size of the fixation balloon 301. The drainage port 303 is located distal to the drainage tube 3, further forward of the pressure-measuring balloon 305.

[0021] In one specific embodiment, the drainage tube 3 is a conventional drainage tube with a drainage port 303 at the distal end and a quick-connect interface 302 at the proximal output port. The quick-connect interface 302 is equipped with an electromagnetic switch valve and a one-way valve. The quick-connect interface 302 is detachably connected to the drainage bag 2. When the drainage bag 2 is nearly full, the electromagnetic switch valve can be closed to quickly replace the drainage bag 2. At the same time, the one-way valve can ensure that the drainage fluid does not flow back.

[0022] In one specific embodiment, the outer wall of the drainage tube is provided with an antibacterial coating. The outer surface of the lumbar cistern drainage tube is coated with an antibacterial coating, which is one of a silver ion antibacterial coating, a nano-silver antibacterial coating, or a silver ion-chlorhexidine composite antibacterial coating. The antibacterial coating inhibits and kills bacteria around the drainage tube by slowly releasing antibacterial components, effectively reducing the risk of intracranial infection and catheter-related infection during drainage. Simultaneously, this antibacterial coating has good biocompatibility, low neurotoxicity, and long-lasting antibacterial effect, making it suitable for long-term indwelling cerebrospinal fluid drainage and ensuring a safe and reliable drainage process.

[0023] In one specific embodiment, the surface of the control box 1 is provided with a touch screen 102, which is used to display the temperature inside the pipeline monitored by the temperature monitoring device and the pressure inside the pipeline monitored by the pressure monitoring device.

[0024] In one specific embodiment, the control box 1 is equipped with an IoT communication module 106 that is signal-connected to the temperature monitoring device and the pressure monitoring device. The IoT communication module 106 is also signal-connected to an external terminal. It can summarize the pressure and temperature parameters collected by the pressure and temperature monitoring devices in real time and send the collected real-time data to an external terminal, such as a compatible mobile app, via IoT wireless transmission technology. Users can view the real-time pressure and temperature data of the drainage tube 3 anytime, anywhere through the mobile app, enabling remote monitoring and dynamic control of key parameters in the drainage process. This facilitates timely detection of parameter anomalies and allows for corresponding handling measures, improving the safety and convenience of the drainage operation.

[0025] Furthermore, the IoT communication module 106 can adopt transmission methods adapted to medical scenarios, such as low-power Bluetooth, WiFi, or cellular networks, to ensure the stability and security of data transmission; the mobile APP has real-time data refresh and abnormal warning functions. When the pressure or temperature parameters exceed the preset reasonable range, the APP can issue a warning to the user through pop-ups, ringtones, etc., and also supports the storage and query of historical data to provide data support for clinical diagnosis and treatment analysis.

[0026] In addition, the control box 1 also includes a power supply for each sensor, the touch screen 102, and the IoT communication module 106, as well as conventional circuit components such as a control circuit board that receives monitoring data and converts it into data displayed on the touch screen 102. The components and circuit connections used are conventional designs in the electrical field and are not innovative points of this application; therefore, they will not be described in detail here.
