Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of lumbar puncture needle for children, this lumbar puncture needle
Design mainly for infantile lumbar puncture feature, specifically used by department of pediatrics and Anesthesia Department doctor, it is ensured that child's lumbar vertebra is worn
Thorn art can smoothly complete at short notice.
Background technology
All the time, in lumbar puncture art, child uses identical lumbar puncture needle with adult.Owing to child coordinates
Degree is poor, when using tradition lumbar puncture needle, easily occurs that lumbar puncture needle is long, nook closing member easily slips, puncture procedure step
The problem such as loaded down with trivial details, causes lumbar puncture often failure, and Normal Diagnosis and treatment to doctor bring a lot of worry, also give infant
Add misery.Therefore, clinical lumbar vertebra puncture operation needs a kind of lumbar puncture needle being exclusively used in child badly.
Utility model content
The problem that the purpose of this utility model is to exist for prior art, it is provided that a kind of easy and simple to handle and safe and reliable
Lumbar puncture needle for children.
To this end, this utility model adopts the following technical scheme that
A kind of lumbar puncture needle for children, including puncture needle tubing and the needle tubing seat of hollow of hollow, described puncture needle tubing
Tail end is connected with needle tubing seat, is provided with nook closing member in described puncture needle tubing, and the tail end of described nook closing member is fixed with needle core base；Described needle tubing
The tail end of seat is provided with the cork suitable with needle tubing seat, and described nook closing member runs through cork and arranges；On described needle tubing seat, connection has and pin
The pressure-measuring pipe that base is connected, and described pressure-measuring pipe is made up of transparent soft material.
Further, described needle tubing seat being additionally provided with cerebrospinal fluid thief hole, the outer end of described cerebrospinal fluid thief hole is provided with stifled
Head.
Further, described puncture needle tubing is made up of transparent soft material.
Further, described puncture needle tubing subscript is shown with length scale value.
Further, on described needle core base, needle handle is held in connection.
This utility model has a following technical characterstic:
(1) needle tubing seat tail end is provided with cork, under cork clamping action, can effectively prevent nook closing member from slipping, and nook closing member is worn
It is not required to take off completely nook closing member due to the fixation of cork when going out；
(2) from pressure-measuring pipe on needle tubing seat, compare connection pressure-measuring pipe in Rhizoma Atractylodis Macrocephalae, decrease in doctor's operating process and take
The step of pressure-measuring pipe, and it is unexpected to effectively prevent the operation occurred during external pressure-measuring pipe, as connected pressure measurement during brain hypertension
Pipe causes cerebrospinal fluid outflow too much, causes the danger such as cerebral hernia；Or cause puncture needle to shift in time connecting pressure-measuring pipe, cause brain ridge
Liquid leaves and takes failure；
(3) it is provided with cerebrospinal fluid thief hole below needle tubing seat, thus is not required to when leaving and taking samples of CSF take off nook closing member,
Open thief hole and get final product specimen taken；
(4) material puncturing needle tubing is transparent soft material, it is simple to observes csf flow artificial situation, and greatly reduces
In child's piercing process, fitness is low, puncture needle tubing deformation caused by limbs twisting, fracture equivalent risk；
(5) puncture needle length of tube is suitable, is more suitable for the needs of spinal puncture of child；
(6) puncture needle tubing and be marked with length scale, it is simple to instruct paracentesis depth；
(7) hold the setting of needle handle to be easy to taking of puncture needle and hold and manipulate.
To sum up, the beneficial effects of the utility model are: safety and reliability is high, it is simple to grasp paracentesis depth, puncture
Needle tubing is not easy to fracture or deform；Can directly carry out cerebral measurement, it is to avoid a series of risks that external pressure-measuring pipe causes；Operation
Simplicity, can directly mention pressure-measuring pipe and carry out cerebral measurement, and leave and take cerebrospinal fluid by cerebrospinal fluid thief hole, be effectively increased in art
The success rate of lumbar puncture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, 1-punctures needle tubing, 2-needle tubing seat, 3-nook closing member, 4-needle core base, 5-cork, 6-pressure-measuring pipe, and 7-cerebrospinal fluid samples
Hole, 8-plug, 9-holds needle handle.
Detailed description of the invention
As it is shown in figure 1, a kind of lumbar puncture needle for children, including puncture needle tubing 1 and the needle tubing seat 2 of hollow of hollow, wear
The tail end of pricker pipe 1 is connected with needle tubing seat 2, is provided with nook closing member 3 in puncturing needle tubing 1, and the tail end of nook closing member 3 is fixed with needle core base 4；Pin
The tail end of base 2 is provided with the cork 5 suitable with needle tubing seat 2, and nook closing member 3 runs through cork 5 and arranges, and cork 5 is made up of rubber；Due to
The resilient clamp effect of cork 5, nook closing member 3 can well be fixed by nook closing member 3 cork 5 when passing needle tubing seat 2；Puncture needle tubing 1
The outer wall being made up and puncturing needle tubing 1 of transparent soft material is labeled with length scale value (not shown)；Connect on needle tubing seat 2
There is the pressure-measuring pipe 6 being connected with needle tubing seat 2, and pressure-measuring pipe 6 is made up of transparent soft material；It is provided with cerebrospinal fluid below needle tubing seat 2
Thief hole 7, the outer end of cerebrospinal fluid thief hole 7 is provided with plug 8.For ease of the manipulation of nook closing member in art 3, needle core base 4 connects and holds
Needle handle 9.In the present embodiment, puncturing needle tubing 1 and use polyurethane material to make, this material has certain intensity and is prone to puncture, also
There is flexural capacity, can restore rapidly after on sale or distortion；Nook closing member 3 uses stainless steel；Pressure-measuring pipe 6 uses transparent moulding
Material flexible pipe.
Operational approach of the present utility model is as follows:
Advise infant to take lateral position of bending over, puncture from waist II to sacrum I intervertebral space.Locally routine disinfection and anesthesia after, wear aseptic
Glove, hold this utility model puncture needle and slowly thrust along spinous process direction, when puncturing needle tubing 1 inserting needle about 3-4cm, can wear out hard ridge
Film and reach subarachnoid space, when the front end of nook closing member 3 is retreated at cork 5, cerebrospinal fluid flow out, vertically mention pressure-measuring pipe 6, by survey
Scale value in pressure pipe 6 reads cerebrospinal pressure number, takes off the plug 8 on cerebrospinal fluid thief hole 7, under connect Specimen bottle and leave and take brain ridge
Liquid specimen, then pushes nook closing member 3, finally extracts puncture needle tubing 1.Point of puncture slightly Pressur hemostatic, is coated with antiseptic gauze and with adhesive plaster
Fixing, lumbar vertebrae puncture operating has i.e. been accused.
