Description
Technical field
The utility model belongs to medical instruments field, is related to a kind of newborn's Multifunctional safe type waist perforating pipe with a scale
Needle.
Background technique
It is very important in basic an inspection item and clinical position examine that lumbar puncture, which is in clinical position,
Treatment means, even if making rapid progress in current science and technology, head B-sonography, head CT, bed side head ultrasound use very extensive feelings
Under condition, Lumbar puncture CSF inspection still plays irreplaceable important function in clinical position.
For newborn since the development of its blood-brain barrier is not perfect, immune function is not perfect, and clinically newborn is easy
The critical state of an illness such as hydrocephalus after existing septicemia, intracranial infection, cerebral hemorrhage, if diagnosis and treatment may seriously affect not in time
Infant prognosis and cause adverse neurological system sequelae.Therefore early diagnosis, early stage Canonical management are with regard to extremely important, lumbar puncture
Diagnosis aiming at above-mentioned serious disease and the irreplaceable important method for the treatment of.
China is not dedicated for neonatal lumbar puncture needle at present.Clinically there are two types of common lumbar puncture needles: 1. traditional waists
The steel needle threaded a needle as the not only thin of the long 8cm of needle core but also grown.Disadvantage: 1. neonatal tissue structurally flexible, it is unobvious to break through sense when puncture,
Needle body not easy to maintain is easy to cause puncture failure perpendicular to lumbar puncture plane when puncture；2. newborn's waist wears required depth
Mostly 1cm~1.5cm, needle body do not have scale, lack accurate quantizating index, and paracentesis depth is not easy to hold；It is punctured when 3. puncturing
Direction with puncture plane holdings vertical success rate height, but needle body is elongated is not easy to keep vertical inserting needle, is easy to appear puncture failure.④
Needle tubing front end is thin, and when there is bleeding, tissue damage, blood clot and tissue are easy plugging and lead to puncture failure；Increase 5. puncturing repeatedly
Loading dye, bleeding, penetration damage risk, increase infant inspection pain.2. currently used is self-control simple lumbar puncture needle (packet
Include the advanced Grade A hospital of most of equipment): 5.5 number sword-shaped needles of clinical pediatric common transfusion are clipped to the hose of end,
Steel needle and hose stump is stayed to use as simple lumbar puncture needle.Disadvantage: it 1. needs voluntarily to clip hose end, may cause to operator
The needle stick injuries of oneself；2. depth of needle is completed by rule of thumb when operation, the depth that needle body does not have scale that cannot accurately understand puncture；
3. homemade simple lumbar puncture needle cannot accurately measure the pressure of cerebrospinal fluid；It is easy 4. the more common lumbar puncture needle in puncture needle front end is sharp keen
Existing penetration damage bleeding；5. puncture needle front opening is small, a small amount of bleeding, which this may result in plugging, leads to puncture failure；6. scalp
It is inadequate to term infant's needle body length of part weight 3.5kg or more that needle does simple lumbar puncture needle, cannot complete to puncture.
For the treatment of hydrocephalus in newborn, Continuous Lumbar, which is worn, puts cerebrospinal fluid as clinical effective treatment method, but waist repeatedly
It wears and will lead to that venipuncture difficulty is increasing and penetration damage probability is higher and higher, be clinically also also referred to as (Ommaya using reservoir
Reservoir) it is used for drainage of cerebrospinal fluid, but technical requirements are higher, and mostly neurosurgery can be completed, many at present large-scale comprehensive
Closing hospital neonates section and basic hospital does not have newborn's neurosurgery, this operation becomes problem clinically, and simple
Newborn's waist, which is worn, can complete most of newborn's internal medicine, thus design one it is simple and easy can the perforating of indwelling newborn's waist
Pipe needle can very good solution clinical problem.
