Anesthesia auxiliary device

Abstract

The invention discloses an anesthesia assisting device which comprises a needle core, an inner sleeve and a movable tube. A tail sleeve is arranged at the tail part of the needle core; a first stepped hole is formed in the inner sleeve and comprises a first front section and a first rear section, and the inner diameter of the first front section is larger than that of the first rear section; the moving tube is located on the first front section, and the inner diameter of the moving tube is smaller than the outer diameter of the syringe end. The tail sleeve of the needle core is inserted into the first front section; a cavity is formed in the inner sleeve, the cavity is communicated with the first front section, the cavity is located between the tail sleeve and the movable tube, the cavity is used for receiving cerebrospinal fluid dripping from the tail sleeve, and test paper is arranged in the cavity; the inner sleeve is made of a transparent material; according to the anesthesia auxiliary device, the cavity is formed in the inner sleeve, cerebrospinal fluid dripping from the tail sleeve is received through the cavity, an anesthetist can conveniently observe whether the cerebrospinal fluid flows out or not, and the operation environment cannot be affected.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an anesthesia assisting device. Background technique [0002] Lumbar puncture is a common anesthesia method. The specific operation method is: insert the puncture needle from the specific spinous process space of the patient's spine, and the needle tip passes through the supraspinous ligament, ligamentum flavum, dura mater and arachnoid mater in sequence, and reaches the arachnoid mater. Subarachnoid space, and then inject anesthesia solution into the subarachnoid space. When the anesthetist holds the puncture needle through the ligamentum flavum and the arachnoid, there is a "falling feeling". This feeling is an important basis for the anesthesiologist to judge whether the needle tip has reached the subarachnoid space. This judgment method is very dependent on the anesthetist's experience and feel. Another way to judge whether the needle tip reaches the subarachnoid space is to...

Problems solved by technology

Another way to judge whether the needle tip reaches the subarachnoid space is to wait to see if there is cerebrospinal fluid flowing out of the puncture needle, but the cerebrospinal fluid is a colorless transparent liquid that is not conspicuous at the tail of the puncture needle; on the other hand, even if there is a small amount of fluid Dripping from the puncture needle may also be the liquid medicine staying in the puncture needle. At the same time, the dripping liquid may also easily affect the surgical environment
