Embodiment 1

[0028] Epidural anesthesia puncture safety detection device, if attached figure 1 , 2 , 3, including a valve body 1, a valve core 2, and a test membrane 3, the valve body 1 is a four-way valve body, and the central axes of the valve core channel 4, the puncture needle channel 5 and the test membrane channel 6 are located on the same horizontal plane , the central axis of the syringe channel 7 is perpendicular to the central axis of the spool channel 4, the puncture needle channel 5, and the central axis of the test membrane channel 6, the spool channel 4 coincides with the central axis of the test membrane channel 6, and the spool channel 4 is perpendicular to the central axis of the test membrane channel 6 , the central axes of the four channels intersect at one point, and the test membrane 3 is sealed and connected with the port of the test membrane channel 6 through the test membrane end cap 11 . Test membrane end cap 11 as Figure 5 As shown, the test membrane 3 is buckl...

Embodiment 2

[0042] The structure of the epidural anesthesia puncture safety detection device is the same as that of Example 1, the inner diameter of the test membrane channel 6 is 18 mm; the inner diameter of the puncture needle channel 5 is 3.5 mm; the inner diameter of the syringe channel 7 is 4.5 mm.

[0043] The steps of the epidural anesthesia puncture safety testing method are the same as those in Example 1, except that 1 ml of normal saline is injected.

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a device for security detection of an epidural anesthesia puncture. The device comprises a valve body, a valve core and a testing membrane. The valve body is a four-way valve body. The testing membrane is arranged at a port of a testing membrane channel in a sealed mode. The valve core comprises a valve core body and a valve rod. The valve core body is tightly installed inside the valve core channel in a sleeved mode. The valve rod can rotate around the valve core channel. Three valve core through holes are formed in the valve core body. When the device is at the injection position or the closed position or the puncture position, the corresponding channel can be arranged at the required closed position by rotating the valve rod. The invention further discloses a method for the security detection of the epidural anesthesia puncture. According to the method and device for the security detection of the epidural anesthesia puncture, whether an anesthesia puncture needle punctures a ligamentum flavum can be visually and effectively detected and prompted, the anesthesia puncture needle reaches an epidural space, pain, caused by puncture failure, to a patient is avoided, operation and teaching by a clinician are also facilitated, and the visual and clear evidence is provided for medical confirmation of complications in anesthesia.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a safety detection device and method for epidural anesthesia puncture. Background technique [0002] At present, epidural anesthesia is widely used in domestic anesthesia clinical circles. Epidural anesthesia is also called epidural space block anesthesia. Local anesthetics are injected into the epidural space to block the spinal nerve root and temporarily paralyze the dominating area. Also referred to as epidural block. [0003] When performing epidural anesthesia puncture, the clinical level is mainly judged based on the change of resistance. When encountering the ligamentum flavum, the resistance increases and there is a sense of tenacity. When the ligamentum flavum is pierced and reaches the epidural space, there is a "feeling of empty space". The clinician can inject anesthetics based on this judgment to reach the predetermined position. The way of judging by h...
