Abstract
The invention discloses a vacuum extractor with sound and light alarming and automatic negative pressure control functions. A negative pressure system is connected with an electric contact vacuum meter; one end of each electric contact in a first group of electric contacts of the electric contact vacuum meter is connected with a light emitting diode (LED) and a buzzer, while the other end is connected with a power supply; when an extraction negative pressure value reaches a preset security negative pressure value, the first group of electric contacts of the electric contact vacuum meter is switched on to make the LED emit light and make the buzzer produce sound; one end of each electric contact in a second group of electric contacts of the electric contact vacuum meter is connected with an electromagnetic valve, while the other end is connected with the power supply; the electromagnetic valve is provided with a negative pressure release outlet; and when the extraction negative pressure value reaches a preset danger negative pressure value, the electromagnetic valve is closed, a pipeline of the extractor is communicated with the external atmosphere and then a negative pressure in the pipeline is securely released by the negative pressure release outlet. The vacuum extractor has the characteristics of simple structure, convenient manufacturing, stability, reliability, strong functions, simple and easy operation and the like, and particularly, can make operators fully focus on the operation of surgical instruments and greatly improve the security of operation.
Description
Technical field
The present invention relates to the extension product ultrasonic monitoring gynecological uterine cavity surgical apparatus of B ultrasonic and the technical field of electric abortion suction unit, refer more particularly to the negative pressure operation by the device of electric contact vacuum meter automatic negative pressure control and sound and light alarm.
Background technology
The system that at present the obstetrics and gynecology operation negative pressure is controlled automatically is general main to be comprised of vacuum extractor, pressure transducer, pump speed control module and computer (single-chip microcomputer), such as ZL200820036366.4, sees Fig. 1.In application process, in advance the negative pressure value of wish control is set in computer control software, when system moves, the pressure that pressure transducer is subject to vacuum extractor produces pressure mould like the signal of telecommunication, pressure transducer converts this signal to digital signal via A/D again and transfers to Computer Processing, form with numerical value or table on computer display shows, therefore the operation doctor of gynecilogical operation intuitively observes the negative pressure value of current system, preset when setting certain value when negative pressure value reaches, thereby computer has reached the purpose that negative pressure value is controlled automatically by the startup of pump speed control module to speed governing or the start and stop of vacuum pump.
In the obstetrics and gynecology operation actual mechanical process, the patient lies on the back on the operating-table, the operation technique person regards to the patient to carrying out operation technique in its vaginal canal, this just is faced with the operating process that the operator should pay close attention to operating theater instruments, also must pay close attention to simultaneously negative pressure value demonstration on the display, this has increased the danger of operating theater instruments operation in operator's operation process virtually.Come automatic negative pressure control with computer simultaneously, complex structure, cost is high, and is out of order easily.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, reliable and stable, in this whole operation process, operation all need not this device is carried out eyesight to observe, and only need observe whole-heartedly a kind of vacuum extractor with sound and light alarm and automatic negative pressure control of the operation of operating theater instruments.
For achieving the above object, the invention provides a kind of vacuum extractor with sound and light alarm and automatic negative pressure control, in negative pressure system, be connected with the electric contact vacuum meter, first group of electric contact one termination of electric contact vacuum meter has LED light emitting diode and buzzer, the other end is connected to power supply, when attracting negative pressure value to reach predefined safety negative-pressure value, first group of electric contact of electric contact vacuum meter connected, and makes LED lumination of light emitting diode and buzzer sounding.
Described vacuum extractor with sound and light alarm and automatic negative pressure control, the electric contact vacuum meter has second group of electric contact, second group of electric contact one termination of electric contact vacuum meter has electromagnetic valve, the other end is connected to power supply, electromagnetic valve is provided with the negative pressure bleed outlet, and when attracting negative pressure value to reach predefined dangerous negative pressure value, electromagnetic valve is connected, suction pipe and external pressure are connected, and negative pressure is by negative pressure bleed outlet safety relief in the pipeline.
The electric contact vacuum meter is a structure of sealing, the inner deformation that copper pipe is produced by negative pressure is ordered about electric contact vacuum meter indicator and is carried out negative pressure exponent, electric contact more than at least two is arranged on this device electric contact vacuum meter indicator, at its dial plate two adjustable two electric contacts that can be corresponding with two electric contacts of indicator are arranged, so just formed the electric power cut-in point of two groups of different pointers.Electromagnetic valve is a normally closed valve, and in the situation of its power path of access failure, it is closed, and negative pressure value and the whole haustorium negative pressure value of drawing are equivalent.
Described vacuum extractor with sound and light alarm and automatic negative pressure control, the electric contact vacuum meter has the 3rd group of electric contact, the 3rd group of electric contact one termination of electric contact vacuum meter has gauge tap, the other end is connected to power supply, being switched on or switched off of gauge tap control vacuum-pump power supply, when attracting negative pressure value to reach predefined danger limit value, the gauge tap action, disconnect vacuum-pump power supply, vacuum pump quits work.
Beneficial effect of the present invention, strong, the characteristics such as operation is simple and easy simple in structure, easy to make, reliable and stable, functional that the present invention has, adjusting for electric contact vacuum meters such as default negative pressure alarming values, only need its panel surface adjusting knob of turn to get final product, especially can make the operator pay close attention to fully physically and mentally the operation of operating theater instruments, improve greatly the safety of performing the operation.
