Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of waist Da Chi constant drainage device.
Background technology
We know that the surface of brain and spinal cord is surrounded by three layers of tunicle, and ecto-entad is followed successively by dura mater, arachnoidea and mantle.Be full of cerebrospinal fluid in the subarachnoid space between arachnoidea and the mantle.The cerebrospinal fluid of subarachnoid space produces at third and fourth ventricles of the brain, flows into subarachnoid space through pipeline then.Cerebrospinal fluid flows down along spinal cord, returns brain at spinal cord pipeline internal return.Cerebrospinal fluid comes from blood plasma, and the vascular mantle that is extended to third and fourth ventricles of the brain top by the blood capillary in the choroid plexus is secreted, and is full of subarachnoid space, myelocoele and whole ventricular system.According to the introduction of department of cerebral surgery postoperative intracranial pressure clinical monitoring standard, the intracranial pressure of human body (ICP) need remain in the certain numerical value, normal ICP is 0.667-2Kpa or 5-15mmHg, too high or too low then people can feel that headache, vomiting, papilloedema, disturbance of consciousness, vital sign change, even produces the pathological changes of cerebral hernia.And when human body generation cerebral trauma or intracerebral lesion, intracranial can hematocele or hydrops, often departs from normally with intracranial pressure, must carry out the outer or focus external drainage of cranium brain by surgical operation this moment, with relief of symptoms, reduce intracranial pressure, treat.The lumbar puncture art is usually used in checking the character of cerebrospinal fluid, to diagnosis cerebrovascular, central nervous system infection sexually transmitted disease (STD) become, after the craniocerebral operations, diseases such as craniocerebral trauma, myeleterosis are significant.Sometimes also can be used for the intrathecal injection medicine, and measure intracranial pressure and whether block with the understanding subarachnoid space.Adopt waist Da Chi drain to alleviate intracranial hypertension effectively, alleviate Heavy craniocerebral injury acute stage malignant diseases haircut exhibition.During waist Da Chi drain, the canalis spinalis built-in pipe is very thin, and a speed is very slow (to be controlled at 5～10ml/h), the transforminal herniation chance is reduced.According to Pascal's law, when ventricles of the brain brain cell system still communicated with cavitas subarachnoidealis spinalis, waist Da Chi pressure and intracranial pressure equilibrium were increased, and were difficult for forming cerebral hernia under the situation of this isostasy.
The apparatus that present domestic neurosurgical treatment hydrocrania, cerebral hemorrhage disease adopt lacks system specifications, and the external drainage device is many to be made up of suspension arrangement, dropping funnel, liquid storing bag, pressure regulator, drainage tube etc.Above-mentioned drainage system complex structure, make loaded down with trivial details, the altitude mixture control inconvenience.Epidural catheter is adopted in traditional lumbar puncture, and this conduit far is narrower than the holing of Tuohy puncture needle on spinal dura mater, and cerebrospinal fluid easily exosmoses, and tube chamber easily stops up, and has both influenced the judgement to drainage flow, easily causes infection again.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and processing and manufacturing is easy, and is easy for operation, and the waist Da Chi constant drainage device of liquid return can not appear in the drain accurate measurement.
The technical scheme in the invention for solving the above technical problem is: a kind of waist Da Chi constant drainage device, comprise the puncture drainage assembly, conduit, liquid-collection bag, it is characterized in that: the puncture drainage assembly is by puncture needle, guide wire, drainage catheter, the liner conduit, Rule adapter is formed, drainage catheter is inserted under the guiding of guide wire, the liner conduit is arranged in the drainage catheter tube chamber, adapter one end in Rule is connected with drainage catheter is terminal, the other end is connected with supravasal cone joint, liquid-collection bag is communicated with drainage catheter by conduit, and the liquid-collection bag bottom is provided with leakage fluid dram cone joint and liquid stopping clamp.
Be connected with three-way valve on the said conduit of this utility model.
Be provided with spring steel wire in the said liner duct wall of this utility model.
The said liquid-collection bag of this utility model is provided with metering scale, and top is provided with anti-backflow device.
Be provided with the liner conduit in this utility model drainage catheter tube chamber, liquid-collection bag directly is communicated with drainage catheter by conduit, on the support that can be suspended on adjustment height.Against existing technologies, this utility model drainage catheter caliber and puncture needle holing match, and have avoided cerebrospinal fluid (CSF) seepage, the liner conduit of band spring steel wire in being provided with in the drainage catheter tube chamber, and anti-bending has guaranteed that tube chamber is unobstructed.By the adjustable patient's intracranial pressure of the suspension height of liquid-collection bag.This utility model is simple in structure, and is easy for operation, reduces the clinical infection probability, can reflect the amount of liquid of drain at any time accurately, safe and convenient to use, is fit to situations such as the patient lies in bed, stands up.Be suitable for doing nontoxic aseptic disposable waist Da Chi constant drainage device.
