For the ease of drawing hydrops from neonate oral cavity, one end of described pipette (1) connects a suction nozzle (8).
Described suction nozzle (8) has a body, described body front end is the suction side (81) that smooth sphere is formed, body is provided with inlet hole (82) and the anti-blockage holes (83) of the connection that intersects, arrange before and after described inlet hole (82), inlet hole front end is positioned on described suction side (81), and inlet hole rear end is positioned at body rear end the one end with pipette (1) and is connected.
In order to prevent being likely to the scuffing to baby oral cavity, described body is front end is the cylinder of sphere, described inlet hole (82) is the circular hole by described cylinder axial centre, and described anti-blockage holes (83) is for be arranged on described cylinder cylinder and the circular hole of a through radial direction.
Installation for the ease of parts each in drainage system, drainage system is additionally provided with an installing component (9), described installing component (9) is sealedly connected on resilient bladder (7) opening, described installing component is provided with the first installing hole and the second installing hole, and described first installing hole and the second installing hole are tightly connected feed liquor check valve (3) and anti-down flow tube (4) respectively.
Further, described anti-down flow tube (4) is stretched in resilient bladder (7) through second installing hole one end, and installation portion is exposed in one end, and its bared end connects described outgassing nonreturn valve (5).
For the ease of the amniotic fluid in taking-up resilient bladder (7) or hydrops, described installing component being additionally provided with the 3rd installing hole, one end of a liquid guiding tube (6) is sealedly connected on the 3rd installing hole, and one end of liquid guiding tube liquid guiding tube (6) is tightly connected a pipe lid (10).
In order to meet packaging and the needs of transport, described pipette (1) is made up of the first pipette (11) and the second liquid pipe (12) and connecting tube (13), first pipette (11) is longer than the second liquid pipe (12), second pipette (12) one end is connected with a corresponding end of feed liquor check valve (3), and the second pipette (12) other end is connected with the first pipette (11) by connecting tube (13).
In order to facilitate the whole device of kneading of holding of hands not have abnormal flavour, described resilient bladder (7) is the sacculus of the antitank grenade shape being made up of silica gel.
Therefore, above-mentioned neonate oral cavity drainage system is summed up has following beneficial effect: 1) by holding the frequency pinched continuously and holding and pinch the negative pressure that the degree of depth controls to be formed, thus the excessive tract damage caused of pressure can be effectively prevent；2) there is an anti-scratch and anticlogging suction nozzle, enter in baby mouth by the convenient plug of the smooth sphere of the body of suction nozzle, because of without scratching baby oral cavity, simultaneously owing to body largest face being provided with anti-blockage holes, it is bigger that its aperture can be arranged, even if therefore imbibing hole is because of foreign matters from being blocked, discharges hydrops also by the anti-blockage holes with larger aperture, and anti-blockage holes is not easily blocked with bigger aperture；3) sample can conveniently be extracted by a liquid guiding tube, as to hydrops is cooked chemistry sample, it is convenient to open end cap and take out from liquid guiding tube.

Detailed description of the invention
Such as Fig. 1, apparatus of the present invention have a resilient bladder 7, one end of feed liquor check valve 3 connects with this resilient bladder 7, the other end connects with pipette 1, form an imbibition one-way flow passage, this passage is when in resilient bladder 7, air pressure is less than atmospheric pressure, and feed liquor check valve 3 is opened, and imbibition is flowed to resilient bladder 7.Resilient bladder 7 also connects with anti-down flow tube 4 one end, this anti-down flow tube 4 other end connects with outgassing nonreturn valve 5 one end, outgassing nonreturn valve 5 other end and atmosphere, form a gas unidirectional circulation passage, this passage is when in resilient bladder 7, air pressure is more than atmospheric pressure, outgassing nonreturn valve 5 is opened, and in resilient bladder 7, gas is discharged.
Installation for the ease of part each in apparatus of the present invention, it is provided with an installation portion 9, and installing hole is set on installation portion 9, in order to dispose valve and the pipeline of correspondence, first installing hole and the second installing hole are such as set in order to be tightly connected feed liquor check valve 3 and anti-down flow tube 4 respectively, the opening of resilient bladder 7 is sealedly connected on one end of this installation portion 9, so as to the end connection corresponding with check valve 3 and anti-down flow tube 4.
Such as Fig. 2, one end of pipette 1 connects a suction nozzle 8, and this suction nozzle 8 will be easy to pipette 1 and insert in neonate oral cavity, is drawn by hydrops.This suction nozzle 8 has a body, and for preventing from scratching neonate children's delicate skin, the suction side 81 that the sphere that this body front end is smooth is formed, body is provided with inlet hole 82 and the anti-blockage holes 83 of the connection that intersects.One preferred scheme is that inlet hole 82 is mutually perpendicular to intersection and connects with anti-blockage holes 83.Arranging before and after inlet hole 82, through body axial direction, inlet hole 82 front end is positioned on the suction side 81 of sphere, and rear end is positioned at body rear end the one end with pipette 1 and connects, and anti-blockage holes 83 is be arranged on described cylinder cylinder and the circular hole of a through radial direction.
Further, resilient bladder 7 is the sacculus of the antitank grenade shape being made up of silica gel, and anti-down flow tube 4 extend into this antitank grenade shape through second installing hole one end and drives in resilient bladder 7, and installation portion 9 is exposed in one end, and its bared end connects outgassing nonreturn valve 5.
Above-mentioned pipette 1 is made up of the first pipette 11 and the second liquid pipe 12 and connecting tube 13, so pipette 1 length can be divided into two-section, it is simple to packaging and transport.Second pipette 12 is arranged on installation portion 9, its length is shorter, and less than the first pipette 11, the first pipette 11 is longer than the second liquid pipe 12, one end of second pipette 12 is connected with a corresponding end of feed liquor check valve 3, and the other end is connected with the first pipette 11 by connecting tube 13.
In order to easily hydrops in resilient bladder 7 be taken out the chemical examination carrying out being correlated with, being also provided with the 3rd installing hole on installing component, be used for installing a liquid guiding tube 6, one end of liquid guiding tube 6 is sealedly connected on the 3rd installing hole, one end of liquid guiding tube 6 is tightly connected a pipe lid 10, in order to airtight liquid guiding tube 6.
During use, operator pinches resilient bladder 7 with hands, the gas in sacculus 7 is made to be discharged by anti-down flow tube 4 and outgassing nonreturn valve 5, form negative pressure condition in sacculus 7, namely in resilient bladder 7 air pressure less than atmospheric pressure, make feed liquor check valve 3 open, the amniotic fluid in baby oral cavity or hydrops are passed through suction nozzle 1 and pipette 1 sucking-off.Refluence pipe 4 in resilient bladder 7, higher than the liquid level of wherein inspiration liquid, makes liquid in inspiration sacculus 7 can not pass through refluence pipe 4 and flows backwards away.As chemically examined to the liquid in taking-up resilient bladder 7, as long as opening the pipe lid 10 of one end of liquid guiding tube 6, toppling over downwards and just may be used.
