Abstract
The utility model relates to medical equipment, particularly a negative pressure value readable suction device for a fetal head. The utility model has the structure that the utility model is formed by the connection of a suction device for a fetal head, a three-way pipe, a vacuum meter and a negative pressure device through rubber hoses. The purpose of the utility model is to provide an improved negative pressure value readable suction device for a fetal head. The utility model has the advantages of reasonable design, simple structure, easy manufacturing, small size, convenient operation, high safety, less possibility of damage, capability of accurately read the value of the zone of negative pressure for a fetal head, etc.
Description
This utility model relates to a kind of medical apparatus and instruments.Specifically a kind of readable negative pressure value vacuum extractor.
In department of obstetrics and gynecology were clinical, the structure of existing vacuum extractor was a top absorption fetal head, and terminal (thin end) joins by a rubber hose and 100CM glass empty needle, forms negative pressure by the suction empty needle.Existing vacuum extractor in use owing to use the glass empty needle, firmly aspirates easily broken; Terminal rubber hose is easily impaired in autoclave process, some damaged minutely rubber hose have elasticity and should not find, cause gas leakage, cause inhale the difference of the negative pressure value that negative pressure and fetus head form, so be difficult to accurately grasp the negative pressure value in vacuum extractor internal negative pressure district, the negative pressure deficiency, the easy slippage of suction nozzle device is done again again and has been prolonged stages of labor, and negative pressure is excessive, fetal scalp is easily impaired, seriously can cause intracranial hemorrhage.
In order to address this problem, the suction pump replacement glass empty needle of using when employing artificial abortion is arranged clinically, but still can not read the internal negative pressure value, and this kind suction pump volume is big, and the inconvenience sterilization has increased the chance that infects.
The purpose of this utility model provides a kind of both safe and reliable, the vacuum extractor of the readable internal negative pressure value of handled easily again, and it can accurately read the numerical value of fetus head negative pressuren zone.
The purpose of this utility model is achieved in that at existing suction nozzle device end and is connected by the same tee T of rubber hose, makes it form two passages, is connected with vacuum meter with negtive-pressure implement respectively.The negative pressure that forms on fetal head portion suction nozzle device top during negtive-pressure implement work can be read by vacuum meter.
With reference to Figure of description, the technical pattern of the readable negative pressure value vacuum extractor of this utility model is done following detailed description the in detail:
Accompanying drawing is a structural representation of the present utility model.
The utility model negative pressure value readable vacuum extractor for fetal head, its structure comprise vacuum extractor (1), rubber Glue flexible pipe (2), three-way pipe (3), vacuum meter (4), stainless steel extracting type negative pressure device (5). It is characterized in that tire Attractor (1) is terminal to link to each other with three-way pipe (3) by rubber hose (2), again by rubber hose (2) respectively with Vacuum meter (4) links to each other with stainless steel extracting type negative pressure device (5).
Embodiment: the readable negative pressure value vacuum extractor of this utility model, shown in the by specification accompanying drawing, add at original suction pump end and to use a tee T, make it become two passages, an end connects negtive-pressure implement, and an end links to each other with vacuum meter.It is simple in structure.High temperature resistant, the autoclave sterilization of rustless steel drawing and pulling type negtive-pressure implement is difficult for fragmentation simultaneously, does not need aerofluxus, directly forms negative pressure.
Negative pressure value readable vacuum extractor for fetal head described in the utility model compared with prior art, has Reasonable in design, simple in structure, easily processing, cost is low, be difficult for broken, and have the safety of use, Reliably, conveniently, can accurately read the characteristics such as numerical value of fetal head section negative pressuren zone, thereby have well and push away Wide use value.
Claims (3)
1, a kind of readable negative pressure value vacuum extractor.It comprises vacuum extractor (1), rubber hose (2), tee T (3), vacuum meter (4), rustless steel drawing and pulling type negtive-pressure implement (5), it is characterized in that the terminal rubber hose (2) of passing through of vacuum extractor (1) links to each other with tee T (3), is linked to each other with rustless steel drawing and pulling type negtive-pressure implement (5) with vacuum meter (4) respectively by rubber hose (2) again.
2, readable negative pressure value vacuum extractor according to claim 1 is characterized in that vacuum extractor (1) links to each other with tee T (3) by rubber hose (2).
3,, it is characterized in that vacuum extractor (1) communicates with vacuum meter (4) and rustless steel drawing and pulling type negtive-pressure implement (5) respectively with tee T (3) by rubber hose (2) according to claim 1, described readable negative pressure value vacuum extractor.
