Abstract
The utility model discloses a breast pump. The breast pump comprises a barrel (1), wherein a piston (2) is arranged in the cavity of the barrel (1); the piston (2) is connected with a handle (3); the outer wall of the barrel (2) adapts to the inner wall of the barrel (1), and the front end of the barrel (1) is provided with a breast pumping port (4); the diameter D of the breast pumping port (4) is between 12 and 16mm; the breast pumping port (4) is of a trumpet shape; and a milk groove (5) is formed on the inner wall of the barrel, and is an annular groove. The breast pump is convenient and flexile to use and convenient to carry, and has the functions of pumping milk and correcting crater nipple and flat nipple.
Description
Technical field
This utility model relates to a kind of breast pump, belongs to technical field of medical instruments.
Background technology
The breast pump that uses is at present become with the suction set of balls by sucker, during use, makes the sucker inner chamber produce negative pressure through squeezing the suction ball, realizes sucking and correcting nipple.Because the bottom surface diameter of sucker is big, negative pressure not only acts on nipple, and acts near the tissues such as skin the nipple; Negative-pressure sucking disperses, and in addition, the negative pressure of inhaling the ball generation is less; And vacuum magnitude also is not easy control; Therefore, this breast pump sucks and corrects the weak effect of nipple, and is not easy to collect milk.
Summary of the invention
This utility model provides a kind of negative-pressure sucking controlled breast pump.
This utility model technical solution is: a kind of breast pump, comprise cylinder, and the inner chamber of cylinder is provided with piston, and piston is connected with handle, and the outer wall of piston and the inwall of cylinder are suitable, and the front end of cylinder is the mouth that sucks.
The said diameter D that sucks mouth is 12~16 millimeters.
The said mouth that sucks is for horn-like.
Cylinder is provided with the milk groove, and said milk groove is a circular trough.
The technique effect of this utility model is: this utility model comprises the piston in cylinder and the cylinder, and the front end of the cylinder of living is the mouth that sucks, and the diameter D of the mouth that sucks is 12~16 millimeters; More bigger than nipple, during use, the mouth that will suck is buckled on the nipple; Through handle, move after making piston, make the piston ante-chamber produce negative pressure; Vacuum magnitude can be controlled through piston displacement, and is easy to use flexible, can have the function that sucks and correct crater nipple and flat nipples.Suck mouth for horn-like, can make the size of cylinder do lessly, both reduced cost, easy to carry again.In cylinder, be provided with the milk groove, can the milk of extracting out be left in the milk groove in advance, be convenient to milk and reclaim, the milk groove that goes in ring is not limited by use angle.
Description of drawings
1, Fig. 1 is this utility model structural representation.
The specific embodiment
Specify below in conjunction with accompanying drawing and embodiment:
As shown in Figure 1, a kind of breast pump of this utility model comprises cylinder 1; The inner chamber of cylinder 1 is provided with piston 2, and the afterbody of piston 2 is connected with handle 3, and the inwall of the outer wall of piston 2 and cylinder 1 is suitable; The front end of cylinder 1 is the horn-like mouth 4 that sucks, and its diameter D is 12~16 millimeters.On the inwall of cylinder 1, be provided with the milk groove 5 that goes in ring.Cylinder 1 adopts transparent medical polyvinyl or vinyl polymer material.
During use, will suck mouthfuls 4 is buckled on the nipple, through operating grip 3, moves after making piston 2, makes the piston ante-chamber produce negative pressure, and vacuum magnitude can be through the control of piston displacement.
The unspecified content of this utility model is prior art; Under the prerequisite that does not break away from this utility model design concept; Various distortion and improvement that those skilled in the art make the technical scheme of this utility model all should be included in the rights protection scope of this utility model.
Claims (4)
