Abstract
The utility model discloses a needle-cylinder breast pump, and relates to the technical field of medical instruments. The needle-cylinder breast pump comprises an outer cylinder and an inner cylinder, an external thread and an upper limit ring are arranged at the upper end of the outer cylinder, the external thread corresponds to an internal thread of the upper limit ring, the inner cylinder is a bent tube, a sealing ring is arranged at the lower end of the inner cylinder and connected with the outer cylinder in a sleeved manner, the upper end of the inner cylinder extends to form a breast cup in a bending manner, a lower limit ring is arranged in the middle of the inner cylinder, and the lower limit position of the bottom of the inner cylinder and the bottom of the outer cylinder form a milk chamber. When the needle-cylinder breast pump is used, milk can be effectively prevented from sticking to the sealing ring at the bottom of the inner cylinder, and movement of the inner cylinder cannot be affected.
Description
Technical field
This utility model relates to technical field of medical instruments, is specially a kind of syringe-type breast pump.
Background technology
Syringe-type breast pump is the auxiliary instrument of milking that the puerpera uses always, be 201220059704.2 as the patent No., name is called the utility model patent of " syringe-type breast pump ", its structure comprises urceolus and inner core, inner core and urceolus socket, establish external screw thread and spacing ring in the urceolus upper end, spacing ring plays a part spacing when sucking, and plays fixedly nipple when breast-feeding.Inner core is the body of a bending, and the inner core lower end is provided with sealing ring, and inner core upper end bending extension is breast cup.The technological deficiency that this breast pump exists mainly is: because the milk liquid chamber is not set, inner core mobile distance in urceolus can only be leaned on people's hand control, if inner core moves too on the lower, then milk can adhere to outer tube side wall, causes the content moving resistance to increase, and uses inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of syringe-type breast pump with milk liquid chamber is provided.
The technical solution of the utility model is such, a kind of syringe-type breast pump, comprise urceolus and inner core, it is characterized in that: described urceolus 1 upper end is provided with external screw thread 1a and upper limit ring 2, and described external screw thread 1a is corresponding with upper limit ring 2 female threads, and described inner core 3 is the body of a bending, inner core 3 lower ends are provided with sealing ring 4 and urceolus 1 socket, inner core 3 upper end bending extensions are breast cup 3a, and spacing ring 3b is set at the inner core middle part, and milk liquid chamber 5 is formed on inner core 3 bottom lower limit and urceolus 1 bottom.
Described urceolus 1 wall is provided with the volume graduation mark.
The beneficial effects of the utility model mainly show: when inner core moves down, when lower limit ring and upper limit loop contacts, inner core arrives lower limit.When inner core moves up, when sealing ring and upper limit loop contacts, inner core arrives upper limit.Tube bottom is established the milk liquid chamber outside, because the lower limit ring is set, when inner core moves down, guarantees that the bottom of inner core can not enter the milk liquid chamber, thereby prevents that milk is bonded on the sealing ring of interior tube bottom, influences inner core and moves.Urceolus upper end is provided with external screw thread, got milk after, use spacing ring nipple be fixed on the urceolus upper end, be convenient to Infantile nursing, milk that will sucking-off is poured other feeding bottle into.Be provided with the volume graduation mark at outer tube wall, be convenient to calculate the milk amount of sucking-off.Inner core upper end bending extension is breast cup, and in use, the position that can lower hands is used lighter.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further.
A kind of syringe-type breast pump, with reference to Fig. 1, comprise urceolus and inner core, described urceolus 1 upper end is provided with external screw thread 1a and upper limit ring 2, and described external screw thread 1a is corresponding with upper limit ring 2 female threads, and described inner core 3 is the body of a bending, inner core 3 lower ends are provided with sealing ring 4 and urceolus 1 socket, inner core 3 upper end bending extensions are breast cup 3a, and spacing ring 3b is set at the inner core middle part, and milk liquid chamber 5 is formed on inner core 3 bottom lower limit and urceolus 1 bottom.
Described urceolus 1 wall is provided with the volume graduation mark, is convenient to calculate the milk liquid measure of sucking-off.
