Background technology
Existing amniocentesis is after routine disinfection drape, under B ultrasonic guiding, vertically penetrate amniotic cavity with 22G*22mm puncture needle through stomach wall, successfully enter after amniotic cavity with manually extraction amniotic fluid of 3 of conventional disposable 10ml syringes, about 20-30ml, makes coherence check altogether.Because needle length has 22G*22mm, tube chamber is thin, extracts amniotic fluid specimen at every turn, and pressure should not be grasped and is unstable, and puncture needle easily left and right teeters, patient's pain, and easily occur that amniorrhexis and seepage cause fetal abortion.For operator, manually extract each pressure that extracts and cannot fix, waste time and energy, patient is required high.
Summary of the invention
The purpose of this utility model is to provide a kind of amniocentesis amniotic fluid harvester of handled easily.
This utility model for the adopted technical scheme that achieves the above object is: a kind of amniocentesis amniotic fluid harvester, comprises puncture needle, gathers flexible pipe, pipe close puncture needle, negative-pressure collecting tube; The front end of puncture needle is pin mouth end, and the rear end of puncture needle is incoming end, and it is horn-like that incoming end is; One end that collection flexible pipe is connected with puncture needle arranges the connection socket coordinating with the horn-like incoming end of puncture needle, the horn-like interface that other end setting is connected with pipe close puncture needle; The end of pipe close puncture needle is the incoming end being connected with the horn-like interface of collection flexible pipe, and the front end of pipe close puncture needle is the cutting tip that pierces through negative-pressure collecting tube seal rubber plug; Negative-pressure collecting tube is the negative-pressure container that the mouth of pipe is provided with seal rubber plug.
Preferably, the length of described collection flexible pipe is at 13～18 centimetres.
Preferably, the internal diameter of described collection flexible pipe is 1.3～1.8 millimeters.
Further, the incoming end horn mouth interior diameter of puncture needle and collection flexible pipe is greater than the insertion end port overall diameter that gathers flexible pipe and pipe close puncture needle, and both diameters are poor is 0.5 millimeter.
Preferably, described puncture needle incoming end horn mouth interior diameter is 4.5 millimeters, and the overall diameter that gathers hose connection socket port is 4 millimeters, and the interior diameter that gathers flexible pipe horn interface is 4.5 millimeters, 15 millimeters of the interface degree of depth; The incoming end port overall diameter of pipe close puncture needle is 4 millimeters.
Preferably, described pipe close puncture needle before use needle tubing portion be provided with protective sleeve.
This utility model can extract amniotic fluid isostasy, and puncture needle is easily fixing, and the puncture time shortens greatly, obviously alleviates anemia of pregnant woman's pain and pressure, reduces patient's operation easier simultaneously.
Brief description of the drawings
Fig. 1 is the schematic diagram of this utility model preferred embodiment;
Fig. 2 is the decomposing schematic representation of this utility model preferred embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of amniocentesis amniotic fluid harvester, comprises puncture needle 1, gathers flexible pipe 2, pipe close puncture needle 3, negative-pressure collecting tube 4; The front end of puncture needle 1 is pin mouth end, and the rear end of puncture needle 1 is incoming end 101, and incoming end 101 is horn-like; One end that collection flexible pipe 2 is connected with puncture needle 1 arranges the connection socket 201 coordinating with the horn-like incoming end of puncture needle, the horn-like interface 202 that other end setting is connected with pipe close puncture needle 3; The end of pipe close puncture needle 3 is the incoming end 301 being connected with the horn-like interface of collection flexible pipe 2, and the front end of pipe close puncture needle 3 is the cutting tip that pierces through negative-pressure collecting tube seal rubber plug; Negative-pressure collecting tube 4 is provided with the negative-pressure container of seal rubber plug 401 for the mouth of pipe.
Gather the length of flexible pipe 2 at 13～18 centimetres.The present embodiment is 15 centimetres.The length that gathers flexible pipe 2 is oversize, and in flexible pipe, space causes greatly negative pressure inadequate; Too short, not easy to operate.
The internal diameter that gathers flexible pipe 2 is 1.3～1.8 millimeters.The present embodiment is 1.5 millimeters.The internal diameter that gathers flexible pipe 2 too slightly can cause negative pressure inadequate.
The incoming end horn mouth interior diameter of puncture needle 1 and collection flexible pipe 2 is greater than the insertion end port overall diameter that gathers flexible pipe 2 and pipe close puncture needle 3, and both diameters are poor is 0.5 millimeter.In the present embodiment, puncture needle 1 incoming end horn mouth 101 overall diameters are 4.5 millimeters, and the interior diameter that gathers flexible pipe 2 connection socket ports 201 is 4 millimeters, and the interior diameter that gathers flexible pipe 2 horn interfaces 202 is 4.5 millimeters, 15 millimeters of the interface degree of depth; Incoming end port 301 overall diameters of pipe close puncture needle 3 are 4 millimeters.Each interface is connected firmly and more seals, air tight.
Described pipe close puncture needle 3 before use needle tubing portion is provided with protective sleeve 303.Protective sleeve 303 can prevent that pipe close puncture needle 3 is contaminated before use.
Negative-pressure collecting tube 4 is negative pressure test tube, and capacity is that 10ml/ props up, 5ml/ props up.Negative pressure test tube can pass through flexible pipe collection of body fluids easily.
When work, centered by point of puncture, carry out disinfection; Under B ultrasonic guiding, puncture needle 1 is successfully punctured and enters amniotic cavity, with gathering flexible pipe 2 connecting puncture needles 1, the other end is taken over plug puncture needle 3, connects negative-pressure collecting tube 4, and amniotic fluid just can slowly enter collecting pipe 4, after collecting pipe 4 is collected full 10ml, negative pressure disappears, and amniotic fluid no longer enters in collecting pipe 4.Extract collecting pipe 4, connect another collecting pipe 4, collect altogether 20～30ml amniotic fluid; Extract fast amniotic cavity puncture needle 1, use aseptic vein pressing to compel puncture needle eye.
Use this utility model to carry out amniocentesis amniotic fluid and gather 30 person-times, all successfully obtain enough amniotic fluid, carry out amniotic fluid specimen cell culture, all successfully carry out the multiple detections such as fetal chromosomal core analysis, thalassemia gene test, gene chip.
This utility model can replace conventional manual syringe and extract amniotic fluid, has the patient's of alleviating pain, reduces the advantages such as abortion ratio, handled easily, has larger practicality and novelty.Can be applicable to prenatal diagnosis amniocentesis technology and obtain fetal cell, carry out the aspects such as fetal chromosomal karyotyping, the fetus poor gene diagnosis in ground, the diagnosis of fetus Disease-causing gene.Application process is simply easy to grasp, and successfully carrying out only needs to connect collection flexible pipe and collecting pipe after amniocentesis, just can carry out prenatal diagnosis by the enough amniotic fluid of automatic acquisition.Extract amniotic fluid isostasy, puncture needle is easily fixing, and the puncture time shortens greatly, obviously alleviates anemia of pregnant woman's pain and pressure, reduces patient's operation easier simultaneously.
