Description
Technical field
The utility model relates to arrive medical equipment technical field, specifically a kind of cerebrospinal fluid collector.
Background technique
Cerebrospinal fluid (Cerebro-Spinal Fluid, CSF) is colorless and transparent liquid, is produced by the choroid plexus in the ventricles of the brain
Raw, similar to the property of blood plasma and lymph, somewhat viscous is filled in each ventricles of the brain, cavum subarachnoidale and myelocoele.Just
Normal cerebrospinal fluid has certain chemical component and pressure, plays an important role to maintenance the relatively stable of cranium pressure.Suffer from central nervous system
It when disease of uniting, is often required to leave and take cerebrospinal fluid and does conventional, biochemical or Bacteria Culture etc. and check, to assist to diagnose.Clinically cerebrospinal fluid
Leave and take method be generally lumbar puncture acquisition, can also from lumbar cistern drainage pipe, extraventricular drainage pipe or Ommaya capsule puncture obtain
?.The sterile glass test tube clinically used at present collects cerebrospinal fluid, and the process of test tube, brain ridge are transferred to after syringe collecting
The probability that liquid is contaminated is larger, and teat glass top cover easily loosens, easy to fall off during transport, causes cerebrospinal fluid
Waste and secondary pollution.Meanwhile the patient for being implanted into Ommaya capsule is when leaving and taking cerebrospinal fluid, it is solid using scalp needle puncture difficulty
Fixed easily to slip, repeated multiple times puncture be easy to cause damage and infection, while cerebrospinal fluid is also easily contaminated.We go out from patient
Hair is to consider emphasis with correct cerebrospinal fluid of safely and effectively collecting in time, devises cerebrospinal fluid collector.
Summary of the invention
To solve above-mentioned defect in the prior art, the utility model provides a kind of cerebrospinal fluid collector, the collector knot
Structure is simple, and puncture needle is not easy to slip, and lid is not easy to loosen, can directly leave and take cerebrospinal fluid will not secondary pollution, be also suitable for simultaneously
Retained with being injected into after syringe collecting in the collector.
The technical solution adopted in the utility model: cerebrospinal fluid collector, including bottle body, conduit, the bottle body have an opening
End and a sealed end, the open end is detachably equipped with a upper cover；The outlet end of the conduit is arranged on lid and extends to
In bottle body；The arrival end of the conduit is connected with puncture needle, and close puncture needle side is equipped with a band self-adhesive on the conduit
Fixed block；An injection pipe fitting is equipped on the conduit at upper cover；It is equipped between injection pipe fitting and the fixed block
For controlling the clip of conduit opening and closing.
Preferably, the bottle body is cylinder ampuliform；The bottle body open end is equipped with external screw thread, be equipped on the inside of the upper cover with
The internal screw thread that external screw thread matches.
Preferably, lower cover corresponding with upper cover size is detachably equipped on the outside of the sealed end of the bottle body；In the lower cover
Side is equipped with the internal screw thread matched with the external screw thread of bottle body open end.
Preferably, non-slip groove is equipped on the outer wall of the upper cover and lower cover.
Preferably, the bottle body is equipped with scale.
The utility model has the beneficial effects that the collector structure is simple, and it is easy to operate, it is fixed using fixed block so that puncture needle
Be not easy to slip, lid is not easy to loosen, directly left and taken using puncture needle cerebrospinal fluid will not secondary pollution, while facilitating and being received with syringe
It is injected into the collector and retains after collection.
