Abstract
The utility model provides a suction device for fetal heads. The utility model is composed of a suction cylinder 1, a medical vacuum meter 6, a pumping gas bag 12. The suction cylinder 1 and the medical vacuum meter 6 are connected with the pumping gas bag 12 by a rubber tube 15. The suction cylinder 1 is a conic metal hollow cylinder, the big end 17 is externally provided with a rubber sleeve 16, and the small end 3 is provided with a short handle 2 and a short handle 5. The short handle 5 is a hollow metal conduit tube and is communicated with the inner cavity of the suction cylinder 1, and the external end is connected with the rubber tube 15 and is communicated with the vacuum meter 6 and the pumping gas bag 12. The pumping gas bag 12 is a ball-shaped rubber bag, two semicircular metal sheets 10 and 13 are lined in the rubber bag, and both ends of a spring 8 are connected with the two metal sheets 10 and 13. Two one-way metal sheet movable flaps 11 and 14 are arranged on both ends of the gas bag 12, and the air inlet movable flap 14 is connected with an air inlet valve 7 and the rubber tube 15.
Description
This utility model relates to the obstetrics and gynecology operation instrument field of medical science, relates to a kind of vacuum extractor particularly.
In the prior art, to the pregnant woman childbirth fetus, vacuum extraction commonly used is to assist giving birth to of fetus, and used vacuum extractor is generally the empty tube of cone-shaped metal, and bleeding to make by needle tubing forms negative pressure in the vacuum extractor.Its shortcoming has: (1) is bled and need can be reached the negative pressure value of expectation for several times repeatedly with needle tubing, and wants two to go into operation, and is time-consuming, and waste of manpower is very inconvenient; (2) generally speaking, it is 0.027-0.04MPa that fetal head attracts needed negative pressure value, and vacuum extractor is not furnished with vacuum meter, thus can not know the accurate numerical value of negative pressure in the suction pump, if the negative pressure deficiency, the easy slippage of suction pump.Negative pressure is excessive, and fetal scalp is injured.
The purpose of this utility model is the shortcoming that overcomes above-mentioned vacuum extractor, provide a kind of reasonable in design, novel structure, only need one man operation, can form required negative pressure rapidly, can show negative pressure value, success rate height, complication are few, easy and simple to handle, the vacuum extractor of saving of work and time.
The technical solution adopted in the utility model is to realize by the improvement design to vacuum extractor.Its major technique feature is by attraction tube 1, and the medical vacuum meter 6 and the air bag 12 of bleeding form by rubber tube 15 connections.Attracting tube 1 is the empty tube of conical metal, and vacuum meter 6 can demonstrate the negative pressure value that attracts in the tube 1.Bleeding is equipped with two and half garden shape sheet metal 10,13 and springs 8 in the air bag 12, and unidirectional foil flap valve 11,14 is assembled at two ends.Extruding gasbag 12 can will attract air extraction in the tube 1 by rubber tube 15.The effect of bleeding by air bag 12 makes and attracts tube 1 to form a negative pressure rapidly, and demonstrates the negative pressure value that attracts in the tube 1 by vacuum meter 6, so just reaches the needed negative pressure (0.027-0.04MPa) of vacuum extraction very soon.So improved vacuum extraction success rate, reduced complication, saving of work and time has alleviated operator's labor intensity.
Fig. 1 is the structural front view of a kind of vacuum extractor of this utility model.
The embodiment that provides in conjunction with the accompanying drawings describes this utility model in detail.
Form by attraction tube 1, medical vacuum meter 6, the air bag 12 of bleeding, rubber tube 15 with reference to figure 1, this utility model.(1) attracting tube 1 is the empty tube of cone-shaped metal, and an end is big, an end is little.Big end 17 is a circular open, and diameter is 5-6cm, external rubber case 16, and for adhering to the fetal head end, a quoit 4 is arranged at small end 3 tops, does tractive and uses.There are corresponding two short handles 2,5 on top place slightly down, is the handle of traction, and short handle 2 is a solid metal, and short handle 5 communicates with attracting tube 1 inner chamber for hollow metal tube, and outer termination rubber tube 15 communicates with the vacuum meter 6 and the air bag 12 of bleeding.(2) vacuum meter on the medical vacuum meter 6 employing electric suction apparatus, it can demonstrate the negative pressure value that attracts in the tube 1.(3) bleed air bag 12 is the spheroidal rubber pocket, and size can be held with one hand and is as the criterion, and it is by air intake valve 7, rubber wall 9, semicircle sheet metal 10,13, spring 8, and air inlet flap valve 14, the flap valve 11 of giving vent to anger are formed.Air intake valve 7 adopts the metal venting valve of sphygomanometer inflatable ball, abuts against the foreign side of air inlet flap valve 14.Be welded on semicircle foil 10,13 central authorities respectively at the two ends that the rubber wall 9 inboard corresponding positions of the air bag 12 of bleeding serve as a contrast 10,13, one springs 8 of attached two and half garden shape sheet metals.The air inlet flap valve 14 and the flap valve 11 of giving vent to anger are unidirectional foil flap valve, and air can only be pressed arrow (→) direction of marking and flow, and air inlet flap valve 14 and air intake valve 7 connect with rubber tube 15.During use,, close air intake valve 7 with attracting the big end opening 18 of tube 1 to cover on the fetal head.One holds the air bag 12 of bleeding, and extrusion spring 8 makes it retraction, and the air in the air bag 12 is extruded out by the flap valve 11 of giving vent to anger; Unclamp hands and remove extruding, then air bag 12 recovers the garden sphere again along with the elastic force of spring 8, is negative pressure in the air bag 12 at this moment, attracts the air in the tube 1 to enter air bag 12 by rubber tube 15 and air inlet flap valve 14.So repeatedly several times, just can make to attract to form in the tube 1 certain negative pressure, the negative pressure that shows when vacuum meter 6 is during at needed numerical value (0.027-0.04MPa), stop air bag 12 and bleed, beginning tractive quoit 4 and short handle 2,5 assist fetal head to give birth to.When fetal head was given birth to vaginal orifice, the air intake valve 7 of outwarding winding made air admission attract to recover malleation in the tube 1, and this moment, vacuum meter 6 demonstration negative pressure were zero.Take off attraction tube 1, vacuum extraction finishes.It is reasonable in design, novel structure, easy and simple to handle, success rate is high, complication is few, save manpower, patient's saving of work and time, the patient is acceptant, is suitable for hospitals at different levels and popularizes.
