Water is the most cumbersome, it is therefore necessary to improve.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of easy to use, and
Amniotic fluid can be avoided excessive, simultaneously can the overall novel membrane puncture needle collecting amniotic fluid.
The purpose of this utility model can be realized by following technical proposal: a kind of novel membrane puncture needle, lives including cylindric
Plug tube and shaft-like push rod, push rod top is fixed with piston, and piston stretches in piston cylinder from piston cylinder afterbody, it is characterised in that: also
Be fixed with the cylindric fluid cylinder of baffle plate including bottom, fluid cylinder top outwards turns down and forms the flange being enclosed within piston cylinder top, also wraps
Including cylindric guide shell and annular connecting plate, guide shell top inwall is radially provided with membrane puncture needle along guide shell, edge in connecting plate
Fixing with guide shell outer wall, outer is fixed with fluid cylinder top inwall, and guide shell outer wall, connecting plate bottom surface and fluid cylinder inwall surround
Forming annular retaining groove, the fluid cylinder inwall that retaining groove cell wall is corresponding is provided with aspirating hole, also includes the bleed-off passage being located in piston cylinder,
Bleed-off passage one end connects with aspirating hole, on other end piston cylinder inwall between baffle plate bottom surface and piston-top surface, and energy
Pull downward on piston, bled by aspirating hole and form negative pressure in making fluid cylinder.
Fluid cylinder is coordinated with piston cylinder top fixing by the flange on top, pulls downward on piston afterwards, pass through aspirating hole
Bleed and form negative pressure in making fluid cylinder, and make membrane puncture needle be punctured by fetal membrane, continue through push rod and pull piston, can smoothly amniotic fluid be inhaled
Entering in fluid cylinder, whole procedure seals is preferable, overall can take out fluid cylinder and changes afterwards, i.e. can be used for subsequent operation, by
It is positioned on the fluid cylinder inwall that retaining groove is corresponding in aspirating hole, is therefore avoided that amniotic fluid enters aspirating hole impact operation.
In the above-mentioned novel membrane puncture needle of one, described guide shell and fluid cylinder are coaxially disposed.
Therefore structure is compacter.
In the above-mentioned novel membrane puncture needle of one, described fluid cylinder is that transparent material is made.
Therefore it is easy to observe.
In the above-mentioned novel membrane puncture needle of one, described push rod bottom is fixed with handle.
Compared with prior art, this utility model has the advantage that
Fluid cylinder is coordinated with piston cylinder top fixing by the flange on top, pulls downward on piston afterwards, pass through aspirating hole
Bleed and form negative pressure in making fluid cylinder, and make membrane puncture needle be punctured by fetal membrane, continue through push rod and pull piston, can smoothly amniotic fluid be inhaled
Entering in fluid cylinder, whole procedure seals is preferable, overall can take out fluid cylinder and changes afterwards, i.e. can be used for subsequent operation, by
It is positioned on the fluid cylinder inwall that retaining groove is corresponding in aspirating hole, is therefore avoided that amniotic fluid enters aspirating hole impact operation.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As it is shown in figure 1, a kind of novel membrane puncture needle of this utility model, including cylindric piston cylinder 1 and shaft-like push rod 2, push rod 2
Top is fixed with piston 21, and piston 21 stretches in piston cylinder 1 from piston cylinder 1 afterbody, also includes that bottom is fixed with the circle of baffle plate 31
Tubular fluid cylinder 3, fluid cylinder 3 top outwards turns down and forms the flange 32 being enclosed within piston cylinder 1 top, also includes cylindric guide shell 4 He
Annular connecting plate 5, guide shell 4 top inwall is radially provided with membrane puncture needle 41 along guide shell 4, outside in connecting plate 5, edge is with guide shell 4
Wall is fixed, and outer is fixed with fluid cylinder 3 top inwall, and guide shell 4 outer wall, connecting plate 5 bottom surface and fluid cylinder 3 inwall surround formation ring
Shape retaining groove 51, fluid cylinder 3 inwall that retaining groove 51 cell wall is corresponding is provided with aspirating hole 33, and bleeding of also including being located in piston cylinder 1 is logical
Road 11, bleed-off passage 11 one end connects with aspirating hole 33, other end piston between baffle plate 31 bottom surface and piston 21 end face
On cylinder 1 inwall, and piston 21 can be pulled downward on, be bled by aspirating hole 33 and form negative pressure in making fluid cylinder 3.
Further, guide shell 4 and fluid cylinder 3 are coaxially disposed.Fluid cylinder 3 is made for transparent material.Push rod 2 bottom is fixed with handle
Hands 22.
Fluid cylinder 3 is coordinated with piston cylinder 1 top fixing by the flange 32 on top, pulls downward on piston 21 afterwards, pass through
