Power the porous type amnion flexible pipe puncture needle reducing operation risk.
In order to achieve the above object, the utility model adopts the following technical scheme that
Porous type amnion flexible pipe puncture needle, including nook closing member, nook closing member joint, flexible pipe, hose coupling；The back segment of nook closing member is fixed on
On nook closing member joint, the back segment of flexible pipe is fixed on hose coupling；Hose Jacket is outside nook closing member, and the head of the front end of nook closing member is from flexible pipe
Front end expose；The detachable leading portion being socketed in nook closing member joint of the back segment of hose coupling.
Preferred as one, the leading portion of flexible pipe is provided with multiple through hole.Through hole can be embarked on journey arrayed in columns, it is possible to is uniformly distributed,
Also can uneven distribution.
Preferred as one, through hole is distributed in the region that the front end of flexible pipe plays 0-2 centimetre backward.
Preferred as one, a diameter of 1 millimeter of through hole.
Preferred as one, it is taper outside the leading portion of flexible pipe, tighten up the front end in flexible pipe.After using this structure, have
It is beneficial to flexible pipe and pass through tissue with what nook closing member smoothed.
Preferred as one, flexible pipe and hose coupling are tightly connected, and nook closing member and nook closing member joint sealing connect.
Preferred as one, the rear end of nook closing member joint is enclosed within a pin beyond the Great Wall.
Preferred as one, the back segment of nook closing member joint or the back segment of hose coupling are socketed on woven hose；The leading portion of pin plug
External diameter, the internal diameter of back segment of nook closing member joint, the external diameter of leading portion of nook closing member joint, hose coupling back segment internal diameter all with transfusion
The external diameter of pipe is identical.After using this structure, after woven hose can be connected on back segment or the hose coupling of nook closing member joint as required
Section.
Preferred as one, the back segment outer ring of hose coupling is provided with external screw thread bayonet socket.After using this structure, work as woven hose
After connecting with hose coupling, can be socketed a threaded connector outside woven hose, external screw thread bayonet socket snaps in threaded connector, protects
Card hose coupling and the firm connection of woven hose, it is to avoid get loose.
Preferred as one, the front end 2-5 millimeter of the front end distance flexible pipe of nook closing member.
Principle of the present utility model is: nook closing member punctures together with flexible pipe, amniotic fluid moment can be avoided to spray equipped with pin plug, wear
Pulling out nook closing member and nook closing member joint after stinging successfully, indwelling flexible pipe and hose coupling operate, and connect hose coupling with woven hose,
Flexible pipe is easy to adjustment direction, is not easily blocked, and greatly reduces corrective surgery painful.At the leading portion design loose structure of flexible pipe, work as tire
When youngster's limbs or adjunct stop the front end of flexible pipe, can proceed with amniotic fluid perfusion, amniotic fluid decrement, amniotic fluid by the through hole of side
Sample reception.
Generally speaking, the utility model has the advantage that
1. simple in construction, easy to make.
2. easy to operate, it is not susceptible to blocking, be greatly improved success rate and the reduction operation risk of operation.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Porous type amnion flexible pipe puncture needle, including nook closing member, nook closing member joint, flexible pipe, hose coupling, pin plug.
The back segment of nook closing member is connected with nook closing member joint sealing, the external diameter of the leading portion of nook closing member joint, the internal diameter of back segment all with transfusion
The external diameter of pipe is identical.Socket for the ease of nook closing member joint and hose coupling coordinates, the leading portion of nook closing member joint slightly tapering.
Flexible pipe and hose coupling are tightly connected, and the internal diameter of the back segment of hose coupling is identical with the external diameter of woven hose.Flexible pipe
It is taper outside at leading portion 5 millimeters, forwards become narrow gradually, tighten up the front end in flexible pipe.The position of the leading portion of flexible pipe 2 centimetres sets
Having multiple through hole, the aperture of through hole is 1 millimeter.The rear end outer ring of hose coupling is provided with external screw thread bayonet socket, and is socketed in woven hose
On threaded connector lock.
The external diameter of the leading portion of pin plug is identical with the external diameter of woven hose, and the socket for the ease of pin plug and nook closing member joint coordinates,
