Embodiment Construction

[0020] figure 1 It is a schematic structural diagram of the epidural pressure detection mechanism of the embodiment, as figure 1 As shown, the needle head of its needle body 3 has an air pressure hole 1; the center of the needle body 3 is a cavity body 2; when in use, the needle core is first put into the cavity body 2 of the needle body 3, and when the needle reaches a certain depth and approaches When the ligamentum flavum is removed, the needle core is drawn out, and the sealing member 4 and the fixed pressure sensor 6 are connected. In order to connect the pressure sensor 6, the rear end of the needle body 3 is sealed with a seal 4; the pressure chamber 5 of the seal 4 communicates with the cavity body 2 and the air pressure hole 1; the pressure sensor 6 is fixed on the pressure chamber 5, and the pressure sensor 6 passes through The lead wire 7 is connected with a detection unit 8, and the detection unit 8 displays the pressure of the air pressure hole 1 entering the cav...

Abstract

The present invention relates to medical detecting device, and is especially one kind of dura mater external pressure detecting mechanism, method and device. The present invention features that the dura mater external pressure signal the dura mater external pressure detecting mechanism detects is first fed to the signal detection unit for filtering and amplifying and then to the signal processing unit for processing in the processor, and the signal processing unit compares the read negative dura mater external pressure value with the set value before outputting the detected dura mater external pressure value and outputting the alarm signal if necessary. The present invention makes it possible to understand the dura mater external pressure easily in epidural anesthesia for successful epidural anesthesia.

Description

technical field [0001] The invention relates to a medical detection device, in particular to an epidural pressure detection mechanism method and device. Background technique [0002] Epidural anesthesia has been used for nearly 80 years. It has been used in China since the 1950s. Due to its perfect pain relief, satisfactory muscle relaxation, fast postoperative recovery, light nursing workload, simple operation, simple equipment, and low cost, it soon became one of the main anesthesia techniques in my country. However, the satisfaction rate (perfect rate) of anesthesia in epidural anesthesia is about 80%, there is still a failure rate of 3.6%, and an imperfect rate of 16.47%. According to the research of Chinese experts on this issue, it has been shown that negative epidural pressure is related to the dura mater puncture pushing away the hard swaying spinal cord, which makes the detection of epidural space pressure a key technology. ...
