Description

Technical Field

[0001] The invention relates to the technical field of spinal intracorporeal pressure monitoring, and in particular to a spinal intracorporeal pressure monitoring system. Background Art

[0002] The spine is composed of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 fused sacral vertebrae, and 3-4 coccygeal vertebrae. When the spine compresses the nerves due to a herniated disc, stenosis of the spinal canal, or tumors or tuberculosis, the following symptoms may occur: First, symptoms of the sensory system. Numbness and pain below the compression plane, or dysfunction of skin temperature regulation and abnormal sweating may occur. If the lumbar vertebrae compress the nerve roots, symptoms of numbness and pain in the lower limbs may occur. Second, changes in muscle strength. When the spine compresses the nerves, symptoms of numbness and weakness of the limbs below the compression plane may occur, and decreased muscle strength may occur. Third, urinary and bowel disorders. In severe cases, constipation or incontinence may occur. At this time, relevant spinal MRI examinations should be performed to evaluate the degree of compression. The degree of spinal cord compression of the nerves should be assessed through physical examinations, and appropriate treatment should be given. In order to check whether the intraspinal pressure affects the patient's spinal disease, doctors will also use the intraspinal pressure monitoring system to monitor the patient's intraspinal pressure in detail during clinical treatment. During use, the sensor cable needs to be inserted into the subcutaneous tunnel so that the pressure sensor probe at the end of the sensor cable can be extended to the internal pressure monitoring point of the spine to detect the internal pressure.

[0003] However, the following problems may exist in the actual use of the spinal body pressure monitoring system: first, it is not easy for the sensor cable to establish a low-profile subcutaneous tunnel, and the bending of the sensor cable will affect the monitoring and monitoring results; second, it is not easy for the sensor cable to smoothly penetrate the subcutaneous tunnel and the subcutaneous tissue. The sensor cable is prone to deviation when entering the subcutaneous tunnel, pressing against the skin and forming bubbles, resulting in reduced detection accuracy. Summary of the invention

[0004] The purpose of the present invention is to provide a spinal intraspinal pressure monitoring system to solve the problems raised in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0008] The good bending ductility of the external flexible nylon tube wrapped around the electrical signal conductor helps to establish a low-profile subcutaneous tunnel. Even if the sensor cable is bent, it will not affect the monitoring. The good hydrophilicity of the water-based epoxy resin on the outer wall of the flexible nylon tube forms a uniform liquid film between the sensor cable and the subcutaneous tissue fluid, ensuring that the sensor cable can smoothly penetrate the subcutaneous tunnel. There is a relative displacement difference between the tissue fluid in the wavy groove on one side of the water-based epoxy resin and the smooth layer on the other side, so that there is a flow rate difference between the tissue fluid on both sides. The Bernoulli principle can be used to make the smooth layer of the water-based epoxy resin close to the subcutaneous tissue, reducing the possibility of the sensor cable pressing against the skin to form bubbles.

[0009] As a further solution of the present invention: the monitoring system module includes a CPU, an electrical signal receiver, an A / D converter, a storage and a WIFI transceiver, the output end of the electrical signal receiver is connected to the input end of the A / D converter, the output end of the A / D converter is connected to the input end of the CPU, the output end of the CPU is connected to the input end of the WIFI transceiver, and the CPU is connected to the storage, the output end of the WIFI transceiver is wirelessly connected to the monitoring host, and the electrical signal receiver is used to receive the electrical signal value of the pressure monitored by the pressure sensor probe.

The A / D converter converts the electrical signal into a digital signal and transmits it to the CPU for analysis and processing. The analyzed and processed spinal body pressure value is stored in the storage and wirelessly transmitted to the monitoring host via the WIFI transceiver. The entire monitoring data processing process is simple and the monitoring accuracy is high.

[0018] Screw the threaded shaft into the corresponding installation internal thread sleeve so that the power terminal one and the power terminal two are connected, which is convenient for later maintenance and repair.

[0019] As a further solution of the present invention: a sealing ring is fixedly connected to the outer edge of the bottom of the mounting internal threaded sleeve, and the bottom of the sealing ring is in close contact with the top of the pressure sensor probe.

[0020] The sealing ring installed between the internal thread sleeve and the pressure sensor probe can ensure the sealing of the pressure sensor probe after it is installed, thereby not affecting the detection of the spinal body pressure.

[0021] As a further solution of the present invention: a plurality of frosted plates are fixedly connected to the outer walls on both sides of the rear cover.
