技术领域 TECHNICAL 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 narcotic puncture, more particularly, to a novel disposable rotary subarachnoid cerebrospinal fluid acquisition, display, pressure measurement devices.

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, the lumbar epidural anesthesia in clinical medicine in many countries has been widely used, the combination of spinal anesthesia anesthesia medication less rapid onset of anesthesia, complete block of the advantages and Epidural anesthesia may need to extend the advantages of surgical anesthesia time, to overcome the single anesthetic defects. 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 lumbar puncture needle is performed epidural anesthesia used in medical devices, it is by and lumbar epidural needle bevel needle supporting the formation. 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 and lumbar epidural needle puncture needle is a needle sheath and needle including core needle body, whether joint or single lumbar puncture needle puncture needle for lumbar puncture in the process of draining cerebrospinal fluid is not easy to control, easy leakage of cerebrospinal fluid with a certain chemical composition and pressure, intracranial pressure to maintain relative stability plays an important role. 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, adverse effects on the body's normal life, can not properly measured cerebrospinal fluid pressure, 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 provides a lumbar puncture needle, the needle seat in front of the needle body portion is provided with a drainage tube drainage tube lumen in communication with the needle body cavity, the lower end of the drainage tube connected to a collection tube, provided with collection tube Ticks, to achieve a cerebrospinal fluid collection, but because of cerebrospinal fluid itself is a viscous liquid, cerebrospinal fluid outflow is not easy, and the drainage tube provided at the front end of the needle on the needle holder, is not conducive to industrialization.

[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 CN202409082U provides a new lumbar puncture needle, with a shut-off valve at the needle end position near the side wall of the needle hub, globe valve with a pressure gauge, the needle end of the drainage tube connected by 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。 On the one hand it is not easy to use the presence of cerebrospinal fluid drainage tube leads to the question, on the other hand the use of gauge pressure measurement, high cost of each gauge, is not conducive to 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 CSF sample, comprising needle, catheter, the catheter is connected at one end to the needle, and the other end of the catheter is connected to a pressure gauge, provided the catheter a three-way, three-way side of the interface side of the tube is connected with a switch on the side of the tube, the end of the tube is provided with sampling bag side. 能够完成脑脊液压力的测量和取样。 Able to complete the cerebrospinal fluid pressure measurements and sampling. 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, in practice this is not conducive to a doctor at the same time sampling, support and switch the rotation, instability will increase support for the patient's pain.
