Description

A kind of automatic cleaning breast pump

Technical field

This utility model relates to a kind of breast pump, particularly relates to a kind of breast pump that can automatically clean.

Background technology

Breast pump, as a kind of instrument that can help to solve some suckling problems and improve suckling quality, is accepted by increasing suckling mother, almost becomes one of necessary tool in puerperal.

Commercially available breast pump is generally divided into manually and electronic two classes.Hand-operated breast pump is simple in structure, is generally all hand-held, and nearly all parts can be dismantled and scalding, and therefore, the cleaning and sterilizing after each use is all implemented than being easier to.But, hand-operated breast pump needs mother oneself to remove high frequency ground long period pressing operation with hands, this physical recovery for first few months in puerperal is totally unfavorable, even may cause the tenosynovitis in finger, wrist and elbow shoulder portion joint, to perinatal health, brings injury.Just because of this, the intelligent electric breast pump of controlling becomes mothers' first-selection gradually.

Electric breast pump is generally comprised of two parts, and a part is hand-held suction nozzle and feeding bottle, and another part is console controller.General together hose connection as gas circuit with an elongated transparent silica gel flexible pipe between these two parts, be built in the negative pressure that the vacuum pump of console controller produces makes hand-held suction nozzle also produce negative pressure by this root flexible pipe simultaneously, due to hand-held suction nozzle, to be that sealing paste is combined in mother supramammary, negative pressure impels milk to flow out, and enter in the feeding bottle being tightly connected with hand-held suction nozzle, thereby complete the process sucking.Because console controller need to be placed in desktop, this root gas circuit flexible pipe generally needs 500mm even longer, and internal diameter is 2-3mm left and right normally, and external diameter is generally 5-6mm left and right.There is airtight plug-in connector at two of gas circuit latex dust, can realize manual airtight plug with hand-held suction nozzle and main frame respectively and be connected.Also the hand electric breast pump of some mini design, console controller design very small and exquisite, can be assembled together with hand-held suction nozzle, does not need the gas circuit flexible pipe exposing.The vacuum pump that is built in console controller is connected with suction nozzle by the gas circuit assembly of a hard, and the negative pressure that vacuum pump produces makes suction nozzle produce negative pressure by this gas circuit assembly, thereby completes the process sucking.

As everyone knows, in breast milk, except a large amount of moisture, approximately 10% is by nutrient substance such as fat, protein.And just from breast of mothers the milk of sucking-off with the waste heat of body temperature, warm breast milk can produce breast milk mist steam, and there is a large amount of fat and protein molecule in this breast milk mist steam, breast milk mist steam can unavoidably make some heavier fat and protein particulate stick on the inwall of gas circuit flexible pipe or hard gas circuit assembly in the process by gas circuit flexible pipe or hard gas circuit assembly, the time sucking is longer, and the fat and the protein particulate that remain on the inwall of gas circuit flexible pipe or hard gas circuit assembly are just more.Breast milk at normal temperatures can only be fresh-keeping 4 hours, and this is known.In like manner, if the human milk fat and the protein that remain on the inwall of gas circuit flexible pipe or hard gas circuit assembly thoroughly cleaned not in time after several hours, also can go mouldy and breed bacteria.Therefore, the manufacturer of breast pump all can require to avoid allowing steam and even milk enter flexible pipe on product description, or completes after sucking at every turn and need to dismantle gas circuit flexible pipe and clean with hot water.

But in actual use, people thoroughly clean gas circuit flexible pipe after being often difficult to accomplish to complete at every turn and sucking.First, a lot of people do not recognize the inwall that fat in breast milk mist steam and protein can remain in gas circuit flexible pipe, or do not recognize the seriousness of this phenomenon; Secondly, mother is busy with baby-sit, after having cleaned hand-held suction nozzle, has tended to ignore the cleaning and sterilizing work of gas circuit flexible pipe; Again, the method being difficult to by hand is thoroughly cleaned elongated hose inner wall part, and general rinsing is difficult to remove completely the booty of hose inner wall.Therefore, washing hose usually becomes the thorny work of mother and baby family, vexatious effort again.If can not thoroughly clean for a long time, transparent hose will be dimmed dirty, unhygienic, also can allow mother feel under the weather.

And the mini electric breast pump that adopts hard gas circuit assembly is owing to being to have adopted integrated design, cannot realize dismounting and the cleaning of hard gas circuit assembly, the breast milk mist steam that contains significant quantities of fat and protein particulate will inevitably remain in the inwall and the gas circuit in vacuum pump of hard gas circuit assembly at all.Remaining in human milk fat in gas circuit flexible pipe or hard gas circuit assembly inwall and protein particulate will go bad and breed bacteria after several hours.Antibacterial may enter hand-held suction nozzle along gas circuit flexible pipe or hard gas circuit assembly, and in entering feeding bottle, this can cause sucking-off breast milk to be polluted, and directly affects infantile health.

Even if gas circuit flexible pipe obtains cleaning and sterilizing, because the vacuum pump of desktop type console controller can not clean, remaining in human milk fat and the protein particulate of gas circuit inwall in vacuum pump not only can affect the long-term behaviour of vacuum pump, more can breed bacteria pollutes latex dust that cleaning and sterilizing has been crossed and even the breast milk in feeding bottle.

Therefore, no matter be to adopt external gas circuit flexible pipe or the electric breast pump of built-in hard gas circuit hose design, as long as whole gas circuit link can not get complete cleaning and sterilizing thoroughly, all in the potential safety hazard that exists in varying degrees sucking-off breast milk to be polluted and fault of construction.If use such breast pump sucking-off breast milk to feed to baby, will bring potential adverse effect to infantile health.

The producer of some electric breast pump adopts new gas-liquid separation or counterflow-preventing design, be that gas circuit flexible pipe separates completely by a silica gel parts (silica gel air bag) and breast milk path, negative pressure from main frame air pump is shunk silica gel air bag, the breast pump body that makes to install silica gel air bag connects the threeway parts inner chamber generation negative pressure of suction nozzle and feeding bottle, thereby in the suction nozzle that makes to be close to breast, produce negative pressure and by breast milk sucking-off, the principle that sucks of Here it is this breast pump.Silica gel air bag must be done and to obtain very thin very soft just can realize moment contraction and diastole, and in the process of sucking, receipts one are put continually, belong to consumable accessory, need frequent replacing guarantee best suction.Under certain conditions, due to the improper silica gel air bag of installing and using or failing more to renew in time, silica gel air bag likely breaks, and this will break the structure of gas-liquid separation, and breast milk mist steam will irreversibly be sucked in the air pump in main frame by moment.Although silica gel air bag can be changed as consumable accessory,, because having gas circuit, main frame cleans design, and the breast milk mist steam that makes suction hose and main frame air pump just in main frame and air pump, becomes the potential safety hazard to sucking-off breast milk by extended residual.In using the process of breast pump, even if silica gel air bag does not have breakage, user also occasional destroys vapor-liquid separating structure because suction silica gel is not in place completely at ordinary times.Usually there is suckling mother to complain that breast milk can blow back in flexible pipe, or see in flexible pipe, there is steam.Therefore,, even if there is vapor-liquid separating structure, can not can not flow backwards by 100% assurance breast milk, or breast milk mist steam can not be inhaled in flexible pipe and air pump.In sum, having gas-liquid separation design and electric breast pump that gas circuit can not be cleaned completely, is also unsafe.
