Description

Technical Field

[0001] The present invention relates to the field of preventing infants from spitting up milk, and specifically to a back-patting device for preventing newborns from vomiting and spitting up milk. Background Art

[0002] Newborns vomiting and spitting up milk are common phenomena during the infant feeding process, especially in the first few months after birth. Due to the limited stomach capacity of newborns, the incomplete development of the stomach structure, and the digestive system being in its initial stage, combined with the easy accumulation of air or gas in the stomach after feeding, the pressure in the stomach increases, leading to phenomena such as vomiting and spitting up milk. Although these situations usually do not belong to serious health problems, they often affect the comfort of newborns and may even cause dangers such as suffocation and choking, and may pose a threat to the health and life safety of infants in severe cases.

[0003] To alleviate this problem, various coping methods and devices have emerged in the prior art, including the following:

[0004] Manual back-patting method: Currently, the most common method for preventing vomiting and spitting up milk is still manual back-patting. After feeding, the caregiver will hold the infant upright in the arms and gently pat the back to help it expel gas. This method relies on the experience and technique of the caregiver, and the back-patting strength and duration vary among different people, and it is easy to have situations where the strength is insufficient or too strong. Moreover, since infants are relatively delicate, too strong or too frequent patting may cause harm to the infant's back.

[0005] Anti-spitting-up milk appliances: Such as air bags, exhaust devices, etc. These devices mostly reduce the phenomenon of spitting up milk by providing a gas discharge channel or external vibration. However, these appliances generally have disadvantages such as inconvenient use, poor comfort, and easy damage. In addition, some devices are too complex to achieve safe and convenient operation, and most devices do not well combine the physiological needs of newborns and often cannot completely and effectively prevent vomiting and spitting up milk.

[0006] Automatic massage and exhaust devices: Help newborns expel gas through electric massage, vibration, etc. These devices usually use mechanical devices to imitate the actions of patting or massaging to help newborns expel gas smoothly. However, the common problem of existing automatic exhaust devices is that the vibration frequency and strength often cannot be accurately adjusted, which may cause discomfort to the infant or poor effect.

[0007] In addition, after the inventor's search, there is also content related to preventing vomiting and spitting up milk in the currently published patent applications, including the following:

[0008] 1) Publication number CN113599105A discloses a new type of medical neonatal care auxiliary anti-regurgitation device. In this patent application, it includes a base, a column fixedly connected to the upper part of the base, and an inclined bed rotatably connected to the top of the column. A restraint strap is provided on the inner side of the inclined bed. One end of the restraint strap is fixedly connected to the bottom plate of the inclined bed, and a through slot for the other end of the restraint strap to movably penetrate is provided on the side plate of the inclined bed. A limiting piece that can elastically connect and limit the restraint strap is elastically connected in the through slot. Through the design of the restraint strap in this application, it can simulate the mother's arm holding the infant, thereby preventing the infant from slipping downward when the inclination angle of the inclined bed is relatively large. It can also hang toys and other objects on the hanging ring to distract the infant's attention and reduce the infant's crying. Through the design of the footrest in this application, it can support the infant's feet and further prevent the infant from slipping.

[0009] 2) Publication number CN115531167A discloses a burping device for newborns to prevent regurgitation, including a support base and two side plates arranged on the support base. A bearing plate is provided between the two side plates, and a bearing pad is installed on the bearing plate. For this burping device for newborns to prevent regurgitation, when the newborn needs to be burped after feeding, the newborn can be directly and slowly placed on the bearing pad, and the head is placed at the shaping headrest. When burping the newborn, after the bearing plate rotates to a certain obtuse angle, and the lifting pad at the burping opening changes from a supporting state to a triangular state at the burping opening, and through the operation of the burping mechanism, further stable burping of the newborn's back from bottom to top is realized. At the same time, the two contact parts deviate from the spine, realizing the protection of the newborn's spine while being able to stably discharge the gas in the newborn's body.

[0010] However, the above exhaust devices all have the following problems:

[0011] Unable to effectively simulate the artificial back-patting action: The traditional manual back-patting method has a certain degree of flexibility and can adjust the strength and rhythm of back-patting according to the specific needs and physical reactions of the baby. Due to technical limitations, existing automatic back-patting devices are difficult to accurately simulate the artificial back-patting action, resulting in the back-patting effect not meeting expectations and being unable to fully meet the needs of the baby.

[0012] Lack of functions to adapt to the needs of different babies: Since the physical conditions and reactions of each baby are different, existing devices lack sufficient adaptability in functions and cannot flexibly adjust according to the individual needs of the baby.

[0013] Poor stability: Existing devices simulate the mother's embrace through restraint straps and use inclined beds and footrests to prevent the baby from slipping. Although theoretically it can prevent the baby from sliding, in actual use, it may cause discomfort or safety hazards to the baby due to improper operation or adjustment. Especially when the baby is crying or constantly moving, the restraint straps and inclined beds may not provide sufficient stability. Summary of the Invention

[0014] The purpose of the present invention is to provide a back-patting device for preventing newborns from spitting up milk or regurgitating milk. Through innovative back-patting design and safe enclosure function, the comfort and safety of infant care are greatly improved.

[0015] To achieve the above purpose, the present invention provides the following technical solution: A back-patting device for preventing newborns from spitting up milk or regurgitating milk, including a horizontal lying frame and a back-patting member. The horizontal lying frame is supported on the ground and is used to provide the correct support required for the baby during back-patting. The horizontal lying frame includes a bottom frame, an adjustment buckle plate, and a horizontal lying plate. The bottom frame is arched, with front support feet and rear support feet respectively arranged at the front and rear ends of the bottom frame. Insertion buckles are arranged at intervals at the end of the bottom frame close to the front support feet. The horizontal lying plate is movably hinged to the middle of the bottom frame through a hinge shaft, and an adjustment buckle plate is arranged in the middle of the bottom of the horizontal lying plate, which cooperates with the insertion buckle when the horizontal lying plate rotates relative to the bottom frame. When the baby uses the lying frame, it can be maintained in a slightly inclined or supported posture, which helps to promote exhaust or reduce the pressure in the stomach, thereby reducing the occurrence of spitting up milk and regurgitating milk. The design of the lying frame allows the baby's head and upper body to be slightly lifted, which helps to prevent gastric acid reflux or choking.

[0016] Preferably, the horizontal lying plate includes a lying plate body, a heating pad, and a blocking airbag. The heating pad is covered on the surface of the lying plate body. The blocking airbag is U-shaped and is distributed on both sides and the bottom side of the lying plate body. A micro air pump is arranged at the bottom of the lying plate body and is connected to the air nozzle on the blocking airbag through a trachea. The heating pad can provide a warm environment for the baby to help it relax. Especially in a cold environment, it can maintain an appropriate body temperature, making the baby's use experience on the lying frame better.

[0017] Preferably, a pressure patch for sensing weight is also arranged on the lying plate body. The pressure patch can be linked with the micro air pump. When the pressure patch senses the baby, the micro air pump supplies air to the blocking airbag, causing the blocking airbag to expand. As the blocking airbag expands, the blocking airbag forms an enclosure area and firmly surrounds the baby on the lying frame. This enclosure area can effectively prevent the baby from turning over or sliding due to instability, thereby enhancing safety.

[0018] Preferably, the back - patting member is installed on the prone - board body and located at the rear side of the blocking airbag. The back - patting member includes a column, a lead - screw sliding - table module, a damping telescopic rod, and a back - patting module. The column is vertically fixed on the prone - board body. The lead - screw sliding - table module includes guide rails, a lead screw, and a moving pedestal. There are two groups of guide rails which are parallelly distributed. The upper end of the column is connected to the guide rails. A lead screw is arranged inside the guide rails, and a first motor for driving the lead screw to rotate is arranged at one end of the guide rails. The moving pedestal is arranged between the two guide rails. A sliding sleeve which is slidably connected to the guide rails and sleeved on the lead screw is arranged at the end of the moving pedestal. The lower end of the moving pedestal is connected to the back - patting module through multiple groups of damping telescopic rods. The back - patting module can move along the back side of the baby along the guide rails through the lead - screw sliding - table module, which can achieve a more precise and flexible back - patting function and adapt to the needs and body types of different babies.

[0019] Preferably, the back - patting module includes an upper bracket, a second motor, a turntable, a rotating rod, a first swing arm, a second swing arm, a V - shaped rod, a left patting frame, a right patting frame, and a back - patting unit. The upper bracket is connected to the lower end of the damping telescopic rod. There is an opening on one side of the upper bracket. The left patting frame and the right patting frame are respectively hinged on both sides of the opening of the upper bracket. The first motor is fixed inside the upper bracket, and the end of the first motor shaft is connected to the turntable. The eccentric side of the turntable end face is hinged to the rotating rod. The first swing arm and the V - shaped rod are coaxially hinged to the free end of the rotating rod. The middle of the V - shaped rod is movably connected to the upper bracket, and the shaft end of the V - shaped rod is hinged to the second swing arm. The upper ends of the first swing arm and the second swing arm extend out from the opening. The end of the first swing arm is hinged to the left patting frame, and the end of the second swing arm is hinged to the right patting frame.

[0020] Preferably, the left patting frame and the right patting frame have the same structure and are both provided with installation long slots. The back - patting unit is installed in the installation long slots through studs and nuts. The back - patting unit is in the shape of an artificial hand and is a vibrating or magnet - repelling type back - patting device with force adjustment. The vibrating or magnet - repelling type back - patting device simulates the effect of back - patting through vibration or magnetic reaction to help the baby exhaust gas and relieve stomach discomfort.

[0021] Preferably, the back - patting unit in the shape of an artificial hand can further improve the comfort and naturalness of the back - patting process and provide a more gentle and fitting nursing method for the baby. The back - patting unit in the shape of an artificial hand can better simulate the artificial back - patting action, help the baby exhaust gas and relieve stomach discomfort, thus effectively preventing phenomena such as spitting up milk and regurgitation. The back - patting module drives the turntable to rotate through the second motor, and drives the first swing arm and the second swing arm to move through the rotating rod, the V - shaped rod, etc. The first swing arm and the second swing arm respectively drive the left patting frame and the right patting frame, which can adjust the positions of the left patting frame and the right patting frame, so as to accurately control the direction of patting. Cooperating with the back - patting device with force adjustment can ensure the comfort and effectiveness of the back - patting process and adapt to the needs of babies of different ages and body types.

The back-patting module can move along the guide rail on the baby's back, thus achieving more flexible and precise back-patting to adapt to the needs and body types of different babies. This makes the back-patting process more natural and avoids problems such as improper strength and frequency that may occur in traditional manual back-patting. In addition, the back-patting unit uses a vibration or magnet repulsion back-patting device with strength adjustment, which can adjust the back-patting strength according to the body types and needs of different babies. This can avoid discomfort or poor effects caused by too strong or too weak back-patting strength, ensure that the back-patting process is more comfortable and effective for the baby, and reduce the phenomena of spitting up and regurgitation.

[0026] 2. The horizontal lying board design of the present invention covers a heating pad on the surface of the lying board, which can provide a warm environment for the baby. Especially in a cold environment, it can effectively maintain the baby's body temperature. This design helps the baby relax during use, improves its comfort, and also helps to promote the baby's digestion and exhaust function.

[0027] 3. The horizontal lying board of the present invention is equipped with a blocking airbag, which can form an enclosure area to firmly surround the baby and prevent the baby from being unstable or sliding during the back-patting process. The blocking airbag is linked with a pressure patch. When the baby uses it, the micro air pump will inflate the airbag to make it expand and form a protective enclosure area, thereby enhancing safety and preventing the baby from turning over or slipping.

[0028] 4. The back-patting unit of the present invention adopts a shape imitating a human hand, making the back-patting process more natural and comfortable. The shape imitating a human hand can better simulate the artificial back-patting action, effectively helping the baby exhaust and relieve stomach discomfort. In addition, due to the adjustable back-patting strength and direction, the present invention can be adjusted according to the needs of babies of different age stages and body types, and has strong adaptability.
