技术领域 FIELD

[0001] 本发明属于麻醉穿刺技术领域,尤其涉及一种新型一次性蛛网膜下腔旋转式脑脊液采集、显示、测压装置。 [0001] The present invention belongs to the technical field of anesthesia puncture, in particular, relates to a novel disposable rotary subarachnoid CSF acquisition, display, pressure means.

背景技术 Background technique

[0002] 近年来,腰椎硬膜外联合麻醉术在许多国家的医学临床上已得到了普遍的应用,该麻醉方法综合了腰椎麻醉的用药量少、麻醉起效快、阻滞完善的优点和硬膜外麻醉的可根据手术需要延长麻醉时间的优点,克服了单一麻醉的缺陷。 [0002] In recent years, lumbar epidural anesthesia in clinical medicine in many countries has been widely used, the combination of less anesthesia spinal anesthesia medication, rapid onset of anesthesia, complete block of the advantages and epidural anesthesia may be necessary to extend the advantages of the procedure according to the anesthesia, anesthesia overcome single defect. 联合麻醉穿刺针是进行腰椎硬膜外联合麻醉术时所用的医疗器械,它是由硬膜外穿刺针和腰锥穿刺针配套形成。 Anesthesia needle is medical equipment lumbar epidural anesthesia used, it is formed by a lumbar epidural needle bevel needle and matching. 现有硬膜外针和腰椎穿刺针都是包括有针套和针芯、针体,不管是联合穿刺针还是单一的腰椎穿刺针,在对腰脊穿刺引流的过程中,脑脊液不容易控制,容易外泄,脑脊液具有一定的化学成分和压力,对维持颅压的相对稳定有重要作用。 Existing epidural needle and lumbar puncture needle and needle guard are including needle core needle body, whether joint or single needle puncture lumbar puncture needle, in the course of lumbar puncture and drainage of cerebrospinal fluid is not easy to control, leakage easily, cerebrospinal fluid having a certain chemical composition and pressure, intracranial pressure have an important role in maintaining relatively stable. 如果脑脊液外泄就会影响颅内压力,对人体正常生活产生不良影响,也不能正常测量脑脊液的压力,使测量结果不准确。 If cerebrospinal fluid leak will affect intracranial pressure, resulting in adverse effects on normal life, normal cerebrospinal fluid pressure can not be measured, the measurement results are not accurate.

[0003] 中国专利CN201595908U提供了一种腰椎穿刺针,在针体上针座前端的部分设有一个引流管,引流管内腔与针体内腔相通,引流管下端连接采集管,采集管上设有刻度线,实现了脑脊液的采集,但是由于脑脊液本身是粘稠液体,脑脊液不易流出,而且引流管设置在针体上针座前端,不利于工业化。 [0003] Chinese Patent CN201595908U provided a lumbar puncture needle, the needle hub distal end portion is provided with a drainage tube, drainage tube lumen in communication with the needle lumen, the lower end of the drainage tube connecting the collection tube, the collection tube is provided tick, cerebrospinal fluid acquisition realized, but since the CSF itself is a viscous liquid, cerebrospinal fluid hardly flows, and draft tube is provided at a front end thereof on the needle hub, is not suitable for industrial.

[0004] 中国专利CN202409082U提供了一种新型腰椎穿刺针,在针管近针座端位置侧壁上设有截止阀,截止阀上设有压力表,针管尾端通过引流管连接引流袋。 [0004] Chinese patent provides a novel CN202409082U lumbar puncture needle, provided with shut-off valve at the end of the side wall near the needle hub, the cut-off valve is provided with a pressure gauge, the trailing end of the needle tube through the draft tube connecting the drainage bag. 一方面使用引流管存在不易将脑脊液引出的问题,另一方面使用压力表测压,每个压力表成本高,不利于工业化生产。 In one aspect using drains cerebrospinal fluid lead to difficult problems of using hand pressure gauge load cells, each high-cost pressure gauge, is not suitable for industrial production.

[0005] 中国专利CN201727540U提供了一种脑脊液检查取样器,包括穿刺针、导管,所述导管的一端与所述穿刺针连接,所述导管的另一端与一压力表连接,所述导管上设有三通,所述三通的侧接口与一侧管连接,所述侧管上设有开关,所述侧管的末端设有取样袋。 [0005] Chinese Patent CN201727540U provides a cerebrospinal fluid sample, comprising the puncture needle, a catheter is connected to one end of the puncture needle, the other end of the conduit is connected to a pressure gauge, disposed on said catheter a three-way, three-way-side interface of the side of the tube is connected to the upper side of a switch tube, with the end-side tube sampling bag. 能够完成脑脊液压力的测量和取样。 To complete the measurement and sampling of cerebrospinal fluid pressure. 不仅使用压力表成本高,而且使用开关和三通,在实际操作中这样是不利于医生同时进行取样、扶持及开关旋转,扶持不稳会增加病人的痛苦。 Not only the use of high pressure gauge costs, and the use of switches and links, so that is not conducive to the doctor in practice simultaneous sampling, rotary switch and support, support instability will increase the suffering of patients.
