Description

Wearable breast pump

Technical Field

The invention relates to the technical field of mother and infant products, in particular to a breast pump.

Background

Breast pumps are important tools for assisting nursing women to pump breast. Early electric breast pumps generally consisted of a main unit and an application unit, and the main unit and the application unit were connected by a flexible air tube. The breast pump has more components, and the main machine and the application components are of a split structure, so the breast pump has larger volume, can only be suitable for fixed places such as families, nursing rooms and the like, and has poor concealment and portability. Along with the popularization of the current domestic breast feeding concept, the lactation period of women is prolonged year by year, more and more women are in the lactation period after walking into the workplace again, and a breast pump which has better concealment and is suitable for being used in public places is urgently needed so as to discharge the milk secreted by the breasts of the breast-fed people in time. Wearable breast pump products suitable for office women have been in use in recent years.

CN 213964594U discloses a "breast pump system" comprising a housing formed at least in part to fit inside a breast shield and a piezoelectric air pump fitted within the housing and forming part of a closed loop system, the piezoelectric air pump driving a separate deformable membrane to generate a negative air pressure, the membrane being removably mounted on the breast shield.

The technical solution of the "breast pump system" described above has the following drawbacks: (1) because the wearable breast pump has a very compact structure, the distance between the negative pressure source and the breast shield and the breast discharging the milk is very short, and a negative pressure buffering air path is not arranged, the direction of the negative pressure air flow in the breast shield is very easy to be asymmetric, so that the extrusion pressure of the negative pressure to the breast is unbalanced, and a breast-feeding person feels uncomfortable when using the wearable breast pump. (2) The system is only formed by the shell and the milk bottle container which can be matched with the shape of human breast, and has no difference from the traditional electric breast pump in technical characteristics and mechanism. (3) The breast shield is made of hard plastic, so that the breast comfort is not high when the system is worn for sucking milk. And (4) when the core assembly is separated from the outer shell, the core assembly can be removed only after the milk storage tank is removed. During the process of unloading the milk storage tank, the milk in the milk storage tank is easy to overflow from the milk storage tank.

Disclosure of Invention

Compared with the prior art, the wearable breast pump is provided with the negative pressure buffering air path, the negative pressure air flow direction in the breast shield flows horizontally, the extrusion pressure of the negative pressure on the breast is balanced, and the comfort of a breast-feeding person is improved when the breast pump is used. When the core assembly is separated from the outer shell, the milk storage tank does not need to be dismounted firstly, and the milk in the milk storage tank cannot overflow from the milk storage tank. And simple structure is convenient, the complete machine cost is lower, can effectively solve prior art's wearable breast pump part more, the structure is complicated and the equipment is comparatively difficult scheduling problem.

The technical scheme of the invention is as follows: a wearable breast pump is formed by buckling and connecting a host machine component and an integrated breast pump component; wherein, the host computer subassembly including control circuit, battery, negative pressure pump and shell, the integration breast pump subassembly including: breast pads and milk containers; the integrated breast pump assembly is characterized in that the integrated breast pump assembly also comprises an air channel bracket and an integrated functional assembly; wherein:

a. the gas circuit support is loudspeaker form, contains: the negative pressure cavity is positioned at the top of the air channel bracket, and the milk outlet is positioned at the lower end of the air channel bracket; a strip flat negative pressure channel groove is connected between the negative pressure cavity and the milk outlet, and the negative pressure channel groove is a concave groove which conducts the negative pressure cavity and the milk outlet.

b. The integrated functional assembly is composed of three regions: the upper area is provided with a butterfly-shaped air bag for separating gas from liquid, the middle area is provided with a long flat negative pressure sealing strip, and the lower area is provided with a one-way valve; the integrated functional component is of an integrated injection molding structure.

c. The integrated functional component is embedded with the gas circuit bracket; wherein, the butterfly-shaped gasbag of integration function block inlays and accommodates in the negative pressure intracavity at gas circuit support top, and the negative pressure sealing strip of integration function block wraps up the negative pressure channel groove of gas circuit support, and the check valve of integration function block then the joint in the below of the milk mouth department of gas circuit support.

The integrated functional assembly is provided with an upward raised strip-shaped protrusion from the butterfly-shaped air bag along the negative pressure sealing strip, and the strip-shaped protrusion is embedded into a groove of a negative pressure channel groove of the air channel bracket and is in close contact with the negative pressure channel groove.

The depth of the groove of the negative pressure channel groove of the air channel support is smaller than the height of the strip-shaped protrusion of the integrated functional assembly.

The thickness of the breast protection pad gradually changes from the front end to the back end to the middle part in the radial direction, and the thickness gradually becomes thinner.

The main machine component is provided with an infrared detection device for realizing real-time detection of the emulsion capacity and a three-axis micro-mechanical digital accelerometer for posture detection of emulsion dynamic detection in a milk sucking process so as to realize control and alarm of the emulsion liquid level.

Has the advantages that: the wearable breast pump has the following characteristics: 1. the biggest difference between the invention and the prior art is that a negative pressure buffering air passage is arranged, namely an integrated functional component. The integrated functional component integrates the butterfly-shaped air bag, the negative pressure channel groove and the one-way valve plate, and has the outstanding advantages that: because a strip-shaped flat negative pressure channel groove is connected between the negative pressure cavity and the milk outlet, the length of the air path is intentionally increased, and meanwhile, the position of the milk outlet is also lowered and kept at a position close to the level with the outlet of the breast protecting pad. Therefore, the negative pressure airflow direction in the breast shield is horizontal, the pressing pressure of the negative pressure to the breast is relatively balanced, and the comfort of a breast-feeding person is increased.

In addition, the size of the movement assembly is reduced due to the design of the integrated functional assembly, the number of parts and injection molds of the parts is reduced, and the assembly process link in the production process is further simplified.

2. In the structure of CN 213964594U 'breast pump system', the milk storage box is not hermetically connected with the movement component; and when core subassembly and shell subassembly separation, must remove earlier and store up the milk box, just can take out core subassembly, the milk of emulsion container overflows from storing up the milk jar very easily. When the integrated movement assembly is separated from the shell assembly, the milk container is still in sealed connection with the three-way milk outlet of the integrated movement assembly. The milk in the milk container is fundamentally prevented from contacting with the air in the separation process, and the defect of milk overflow is avoided.

3. The breast receiving portion of the present invention is unique in structure: the thickness of the breast-protecting pad gradually changes from the front end to the back end to the middle part in the radial direction, and the thickness gradually becomes thinner. The inner breast protection pad in contact with the breast is made of soft and flexible materials, and the outer support is made of hard plastics. The nursing person wears the nursing pad on the body, and the soft nursing pad contacts with the breast, and the sense of comfort is multiplied. In addition, when the negative pressure suction force is generated, the breast protection pad can automatically contract due to the large difference between the internal air pressure and the external air pressure, and can automatically recover the original shape when the negative pressure is released. Therefore, the breast protecting pad is attached to the areola and kneads the areola to play an effective massage role, thereby generating the effect of inducing lactation. In addition, in the process, the outer sleeve bracket plays a role of rigid support, prevents the cup edge from overturning, and guides the side surface of the reinforced inner sleeve breast pad to shrink towards the middle. Secondly, in the prior art, the connection port of the breast protection pad in butt joint with the transition chamber of the three-way suction device is generally positioned on the axial line of the inner breast protection pad, and a certain amount of residual milk can be retained in the inner breast protection pad after the milk is introduced into the milk storage bottle by negative pressure. In order to overcome the defects, an eccentric connecting port for butting the breast protection pad and the bracket is positioned at the lower end of the central axis of the inner breast protection pad, so that the position of an emulsion outlet is positioned at the lowest point of the whole inner breast protection pad, and residual milk cannot be retained on the breast protection pad when normal pressure is recovered.

4. Since the wearable breast pump is secured to the breast of a mammal, the stability of the milk container is directly affected by the mammal, both during walking and milk expression. Therefore, the host machine component is also provided with an infrared detection device for realizing real-time detection of the milk volume and a three-axis micro-mechanical digital accelerometer for posture detection of dynamic detection of milk in a milk pumping process so as to realize control and alarm of the milk liquid level.

In conclusion, the breast pumping principle of the invention applies the anthropomorphic simulation, and the negative pressure path of the breast of a nursing female and the stimulation manner of lactation are kept consistent when the baby sucks breast milk. The negative pressure cavity is connected with the milk outlet by utilizing the strip-shaped flat negative pressure channel groove, the direction of the negative pressure acting on the breast of the human body is from the breast protecting pad to the milk outlet, the thickness of the breast protecting pad is gradually reduced from two ends to the middle, the thinner area in the middle of the breast protecting pad can be deformed more easily under the action of the negative pressure, the areola part of the human body is extruded and massaged, the areola part is consistent with the conditioned reflex arc of the natural lactation of the human body, and the electric breast pumping can be closer to the natural lactation.
