Abstract

The invention discloses a negative pressure detection device for epidural anesthesia. The device comprises a puncture outfit and a negative pressure sampling tube, wherein the negative pressure sampling tube is movably inserted into the puncture outfit. The invention further discloses a negative pressure detection method for detecting epidural puncture. The detection method comprises the steps ofpuncture detection and cathetering detection. The negative pressure detection device has the advantages that under the dual actions of pressurizing after liquid is injected by using an epidural spaceand negative pressure drawing of the negative pressure sampling tube, the liquid which automatically flows back and drips into the negative pressure sampling tube and is manually injected into the epidural space can be directly observed; the device is used for positioning indication of an epidural puncture needle or an epidural catheter in the epidural space; injection of local anesthetics in theblood vessel is prevented; toxic response of local anesthetics and formation of epidural hematomas are effectively prevented, and precise and safe anaesthetic injection is achieved; the method is precise, reliable, simple and easy to implement, visualized operation is achieved, the method is suitable for various operations of different stages, ages and genders under the epidural anesthesia, it isensured that anesthesia is precisely and safely implemented; the device can help epidural anesthesia teaching; the device is suitable for all kinds of hospitals.

Description

Technical field: [0001] The invention relates to a negative pressure detection device and a detection method for epidural anesthesia, belonging to the field of medical equipment. Background technique: [0002] Epidural anesthesia (also known as epidural block): It is one of the anesthesia techniques widely used in clinic, because of its small impact on cardiovascular, respiratory and gastrointestinal functions, definite analgesic effect, muscle relaxation Good, economical and practical, it has always played an irreplaceable role in clinical anesthesia and pain treatment. Scope of epidural block: surgical anesthesia, postoperative analgesia, labor analgesia, pain treatment for neck, chest, abdomen, lumbar base, perineum, lower limbs and feet. surgery etc. [0003] Epidural anesthesia includes two links of epidural puncture and epidural catheterization. [0004] Epidural puncture still generally adopts blind exploration operation (that is, non-visual traumatic operation), w...
