Abstract

A mammary suction pump apparatus has a suction pump for producing a continuous suction which is connected through the intermediary of a rotating valve to a terminal for the connection of a collecting reservoir. Normally, the collecting reservoir is, when used for a human, connected to a nipple shield. The rotating valve is arranged to connect the suction pump to the terminal so that a continuous suction is produced and upon rotation of the valve the vacuum is arranged to be destroyed so as to produce a pulsed suction.

Description

SPECIFICATION A mammary suction pump apparatus and method of operating the same This invention relates to a mammary suction pump apparatus and method of operating the same, and particularly, although not exclusively, to an apparatus and method for use with human mammaries.
In a known apparatus there has been provided a a continuous suction by the use of a suction pump but it has been found that such continuous suction can cause tissue damage. One known manner in which this disadvantage has been overcome is to provide a motor driving a reciprocal piston within a cylinder such that the reciprocating piston provides a pulsating suction. Such a reciprocating piston however has the disadvantage of numerous moving parts and requires seals to be positioned around the piston to produce effective suction.
The present invention seeks to provide a mammary suction pump and a method of operating the same which is less expensive to produce and which embodies fewer moving parts.
According to this invention there is provided a mammary suction pump apparatus including a suction pump arranged to produce a continuous suction which is connected through the intermediary of a rotating valve to a terminal for the connection of a collecting reservoir, whereby in operation the rotating valve produces suction pulses.
Conveniently, the suction pump is of the diaphragm type and is driven electrically.
Advantageously, the rotating valve comprises a first port for connection to the suction pump, a second port for connection to said terminal and an electrically driven shaft in which is disposed an aperture for interconnecting said first and second ports to, in operation, destroy the vaccum produced by said suction pump and thereby to produce said suction pulses.
Preferably, the rate or revolution of the rotating valve is in the range 47 to 50 R.P.M. to produce the suction pulses at an identical rate.
Advantageously, the pump and the rotating valve are each connected to a respective silencer.
Usually an overflow reservoir is connected between the terminal and the collecting reservoir and when the apparatus is used for a human, a nipple shield is connected to a collecting reservoir.
In a further aspect of the invention there is provided a method of operating a mammary suction pump including the steps of providing a continuous suction by a suction pump and breaking said continuous suction by a rotating valve to thereby produce suction pulses.
Preferably, the strength of said suction pulses is variable by adjusting the vacuum produced by said pump.
The invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in block schematic form a mammary suction pump in accordance with this invention, and Figure 2 shows in partial section a rotating valve used in the invention.
In Figure 1 a mammary suction pump apparatus 1 has an adjustable diaphragm pump 2 connected through a motorised rotating valve 3 to a terminal 4. The input of the diaphragm pump 2 is connected to a silencer 5 and an input of the motorised rotating valve 3 is connected to a silencer 6. The diaphragm pump has a continuous action suction the strength of which is variable by adjusting the vacuum and may be pump such as that produced by Charles Austin Pumps Limited, Model Kapex 2D. The rotating valve 3, shown particularly in Figure 2, has a body 31 within which is rotatably mounted a shaft 32 which is connected to an electrical motor 33 through the intermediary of a gear box 34. The shaft 32 is drilled to form a blind hole 35 extending axially along the shaft and a hole 36 extending radially through the wall of the shaft extends into the hole 35.The end of the shaft 32 remote from the gear box 34 extends to a port 37 which is arranged to be connected to the terminal 4. Mounted perpendicularly to the shaft 32 is a further port 38 which is arranged to be connected to the continuous action diaphragm 2.
A flexible tube 7 has one end connected to the terminal 4 and its other end connected to an overflow jar 8. A further flexible tube 9 is connected between the overflow jar 8 and a collecting jar 10 having an input connected by a flexible tube 11 to a glass nipple shield 12.
In operation the nipple shield 12 is positioned on a user's breast and the diaphragm pump produces a pressure of 200 mm of mercury atmospheric pressure. The vacuum produced by the diaphragm pump 2 is exerted on port 38 and the shaft 32 is rotated at a speed in the range 47 to 50 R.P.M. When the hole 36 does not align with the port 38 a constant suction is produced at the nipple shield 12 but when the hole 36 aligns with the port 38 so that the port 38 is interconnected to the port 37 that the vacuum is momentarily destroyed, thereby producing a pulsed suction at the rate of rotation of the shaft 32. A control knob (not shown) is provided on the diaphragm pump 2 so as to control the strength of the suction which may thus be varied according to a particular user's requirements.
By utilising a continuous action diaphragm pump and a rotating valve the number of moving parts and the expense of such apparatus is greatly reduced in comparison with the known prior art apparatus.
