Abstract
The utility model relates to a single-cavity porous lumber puncture needle for combined spinal epidural anesthesia, which belongs to the technical field of medical appliances. The single-cavity porous lumber puncture needle consists of an epidural puncture needle tube, an epidural puncture needle core, a spinal anesthesia puncture needle tube and a spinal anesthesia puncture needle core, and four to eight drainage openings are disposed on the periphery of one side of a lower end opening of the spinal anesthesia puncture needle tube and communicated with a drainage cavity, and the diameter of each drainage opening ranges from 0.2mm to 0.4mm. The single-cavity porous lumber puncture needle expands contact area of drainage cerebrospinal fluid by aid of the drainage openings on the spinal anesthesia puncture needle tube, and resolves the problem that in the prior art, human tissue is attached on a needle hole of the spinal anesthesia puncture needle due to over low pressure of cerebrospinal fluid, and the cerebrospinal fluid can not flow out normally so that medical staff can not judge whether lumbar puncture is successful or not. The single-cavity porous lumber puncture can smoothly drain out the cerebrospinal fluid, brings convenience for preparing spinal anesthesia medicine with equal proportion, has the advantages of simple structure, easy production and convenient use, and is particularly applicable to clinical combined spinal epidural anesthesia.
Description
Technical field:
This utility model relates to a kind of single-cavity porous combined spinal-epidural lumbar puncture needle, belongs to technical field of medical instruments.
Background technology:
It is common clinically basic operation technology that waist is worn art, during as clinical combined spinal-epidural anesthesia, need to dispose Deng proportion lumbar anesthesia medicament with cerebrospinal fluid, its operating process is: after at first using anesthesia spinal needle with the cavum epidural puncture success, reuse lumbar anesthesia puncture needle enters in the subarachnoid space by the drainage lumens puncture of anesthesia spinal needle, after cerebrospinal fluid flows out from the drainage lumens of lumbar anesthesia puncture needle, collect cerebrospinal fluid such as finishes at the configuration of proportion lumbar anesthesia medicament, drainage lumens by the lumbar anesthesia puncture needle is injected in the subarachnoid space then, finishes anesthesia procedure.
During present clinical combined spinal-epidural anesthesia, because of multiple reason, low excessively such as cerebrospinal pressure, tissue is first-class attached to the pin hole of lumbar anesthesia puncture needle, cause cerebrospinal fluid normally not flow out from lumbar anesthesia puncture needle drainage lumens, make the medical worker can't judge whether successful waist is worn, need repeated localised puncture to judge correctly whether the lumbar anesthesia puncture needle is punctured to subarachnoid space, its result one very easily causes the patient tissue damage, causes hemorrhage, infection; The 2nd, bring inconvenience to medical worker's work.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, the single-cavity porous combined spinal-epidural lumbar puncture needle that practicality is good; This lumbar puncture needle is the conduction hole that communicates with lumbar anesthesia puncture needle drainage lumens that is provided with by lumbar anesthesia puncture needle termination, reach and make cerebrospinal fluid from the normal effusive purpose of lumbar anesthesia puncture needle drainage lumens, when having clinical combined spinal-epidural anesthesia now to solve, tissue is attached on the lumbar anesthesia puncture needle pin hole, cause cerebrospinal fluid normally not flow out, make the medical worker can't judge that whether successful waist wear problem from lumbar anesthesia puncture needle drainage lumens.
This utility model is to realize above-mentioned purpose by the following technical solutions:
A kind of single-cavity porous combined spinal-epidural lumbar puncture needle, it is made of epidural puncture needle tubing, epidural puncture nook closing member, lumbar anesthesia puncture needle tubing, lumbar anesthesia puncture nook closing member, epidural puncture needle tubing upper end is provided with syringe handle a, and epidural puncture nook closing member upper end is provided with nook closing member handle a; Lumbar anesthesia puncture needle tubing upper end is provided with syringe handle b, and lumbar anesthesia puncture nook closing member upper end is provided with nook closing member handle b; It is characterized in that: lumbar anesthesia puncture needle pipe box is inserted in the epidural puncture needle tubing, the lower end circumference of lumbar anesthesia puncture needle tubing is provided with draining hole, the drainage lumens of draining hole and needle body inside connects, described draining hole diameter is 0.2～0.4mm, quantity is 4～8, and described draining hole is the symmetry shape setting.
This utility model beneficial effect compared with prior art is:
This single-cavity porous combined spinal-epidural puncture needle has enlarged the contact area of lumbar anesthesia puncture needle drainage of cerebrospinal fluid and the orientation of contact by side setting and the draining hole drainage lumens perforation at lumbar anesthesia puncture needle tubing.Avoided existing because of cerebrospinal pressure is low excessively, on the pin hole of tissue attached to lumbar anesthesia puncture needle tubing, cause cerebrospinal fluid normally not flow out from lumbar anesthesia puncture needle drainage lumens, make the medical worker can't judge whether successful waist is worn, and easily cause patient tissue damage, cause problem hemorrhage, that infect and bring inconvenience for medical worker's work.This utility model can make cerebrospinal fluid extract out smoothly, made things convenient for the configuration that waits proportion lumbar anesthesia medicament, and has simple in structurely, produces easily, and characteristics easy to use are used when being specially adapted to clinical combined spinal-epidural anesthesia.
