Description

Technical Field

[0001] The invention relates to the technical field of intelligent medical devices, and in particular to a sucking and swallowing sequence function training device for premature infants. Background Art

[0002] Premature infants refer to infants whose gestational age is 28 weeks but less than 37 weeks. Their organ functions and adaptability are poor and they need special care. Studies have found that more than 40% of premature infants have varying degrees of swallowing dysfunction, and up to 80% of premature infants are prone to oral feeding difficulties due to factors such as immature sucking and swallowing functions. To address this problem, intervention measures such as non-nutritive sucking (NNS) and comprehensive oral motor training are currently used to improve the oral feeding ability of premature infants. However, the above-mentioned training mostly relies on professional medical staff to operate, and each training session lasts about 5-20 minutes, with multiple training sessions a day. The intervention time is long, which is not only easy to cause feeding fatigue and reduce the training effect, but also increases the psychological pressure and economic burden on the families of premature infants.

[0003] In response to the above problems, there are currently many patent documents that disclose some intelligent training devices and methods, which use intelligent equipment to replace manual operation, liberate manpower and improve efficiency; for example, the Chinese invention patent with publication number CN117205065A discloses a premature infant oral training device, which realizes intelligent training by setting a heating module, a massage module, a rotation module, and a telescopic module; the device can replace manual operation to a certain extent, and can adjust the training plan according to the training situation of each newborn, thereby improving the strength of various muscle groups in the premature infant's mouth to improve the coordination between sucking, swallowing and breathing.

[0004] However, the above technical solution does not provide a concrete device structure, and mainly conducts training from the aspect of oral massage. In actual application, it can usually only improve the sucking function of premature infants, while the training of swallowing function mainly depends on the spontaneous production of infants, so the effect on improving the swallowing ability of premature infants is limited. In summary, the present application has developed a sucking and swallowing sequence function training device for premature infants, which can conduct orderly training according to the physiological process of the human body sucking first and then swallowing, thereby effectively improving the sucking and swallowing ability of premature infants, thereby improving the oral feeding efficiency and feeding effectiveness of premature infants, and promoting the subsequent completely autonomous oral feeding ability. Summary of the invention

[0005] The present invention aims to provide a sucking and swallowing sequence function training device for premature infants, so as to solve the technical problem that the existing oral massage device has a poor effect on the sucking and swallowing function training of premature infants.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] A sucking and swallowing sequence function training device for premature infants comprises a main body and a training nipple detachably connected to the main body, wherein the main body is provided with a controller, a power supply and a driving mechanism electrically connected to the controller for driving the training nipple to move, wherein the driving mechanism comprises a rocker and a push rod, wherein the push rod is slidably arranged in the rocker, and the power output end of the push rod extends out of the rocker, and the free end of the rocker extends out of the main body and is connected to the training nipple; a milk cavity is arranged in the training nipple, a piston is slidably and sealedly arranged in the milk cavity, an injection head is further arranged at the front end of the training nipple, and the injection head is communicated with the milk cavity; a connecting hole is arranged at the rear end of the training nipple, the connecting hole is connected to the rocker, and the push rod is used to push the piston to slide in the milk cavity;

[0008] The outer surface of the main body is also provided with an input module and a display module electrically connected to the controller. The input module is used to pre-input training items, which include sucking training and swallowing training. The input module sends the training items to the controller. After receiving the signal, the controller first controls the rocker movement to perform sucking training. When the sucking training reaches the preset time, the push rod is controlled to perform swallowing training according to the preset milk injection frequency; the display module is used to display the time and action frequency of the sucking training and swallowing training.

[0009] Technical principles and beneficial effects:

[0010] 1. By setting a controller and a driving mechanism on the main body, a training plan can be pre-set according to the situation of each premature baby, and then the controller can automatically control the action of the driving mechanism, and the automated training can replace manual operation to improve the training efficiency and training effect. For example: when sucking training is performed, the controller controls the rocker to move in the premature baby's mouth according to the preset swing amplitude and frequency, thereby stimulating the hard palate to induce a foraging reflex, thereby inducing a sucking action and achieving sucking training; when swallowing training is performed, the rocker remains in the neutral position, and the controller controls the push rod to move according to the preset push frequency and push the piston, thereby pushing the milk in the milk cavity into the middle and posterior area of ​​the premature baby's tongue, inducing a swallowing action and performing swallowing training.

[0011] 2. By making the training nipple detachably connected to the main body, it is easy to disassemble, replace and clean the training nipple, and the controller, drive mechanism and other electronic control parts are centrally arranged on the main body, which can improve versatility and reduce use costs.

[0012] 3. By setting a milk cavity in the training nipple and injecting the required amount of milk into the milk cavity from the injection head before training, when the sucking training is completed, swallowing training can be directly carried out without taking out the training nipple. Compared with the existing method of using a hole-free pacifier to train sucking and then using a syringe to push milk into the posterior tongue area of ​​the premature infant, the operation steps of the present application are simpler, and the training nipple is also in the premature infant's mouth when pushing milk, which can simulate a real oral feeding environment and induce sucking during swallowing training, thereby realizing the continuous actions of sucking, swallowing, sucking, and swallowing.

[0013] 4. By setting an input module on the main body, it is convenient to formulate a training plan, and the training project of this application adopts sucking and swallowing sequential training steps, which is more in line with the physiological process of the human body sucking first and then swallowing, and can effectively improve the oral feeding efficiency and feeding effectiveness of premature infants, thereby shortening the oral feeding transition time of premature infants; compared with the existing technology, it effectively promotes the development and improvement of the sucking and swallowing functions of premature infants.

[0014] In summary, the present application not only provides a concrete training device and achieves the goal of intelligent training, but also improves the training efficiency compared to relying on manual operation; it can also perform sucking and swallowing sequence function training according to the physiological process of the human body. The training methods are more scientific and complete, which effectively promotes the improvement and development of the sucking and swallowing functions of premature infants, improves the efficiency and effectiveness of oral feeding of premature infants, and effectively shortens the transition time of oral feeding of premature infants.

[0015] Preferably, as an improvement, a communication module and an alarm module are also provided on the controller. The communication module is wirelessly connected to the oximeter. When the oximeter detects abnormal data, a signal is sent to the controller. After receiving the signal, the controller controls the driving mechanism to stop moving and controls the alarm module to sound an alarm.

[0016] Beneficial effects: The blood oximeter is connected to the premature infant to monitor the blood oxygen level in real time. Signal transmission is achieved by setting up a communication module. When the blood oxygen level drops during sucking and swallowing training, the signal is immediately sent to the controller. After receiving the signal, the controller controls the drive mechanism to stop moving and controls the alarm to sound an alarm, thereby warning the nursing staff. Compared with relying on the naked eye to judge, it has higher accuracy and timeliness, ensuring safety of use.

[0017] Preferably, as an improvement, an installation cavity is provided on the main body, a swing cylinder is provided at the bottom of the installation cavity, the swing cylinder is electrically connected to the controller, a connecting shaft is fixedly provided at the output end of the swing cylinder, the bottom of the rocker is fixedly connected to the connecting shaft, and the rocker is driven by the swing cylinder to swing in the installation cavity.

[0018] Beneficial effect: Using a swing cylinder to drive the rocker to swing can accurately control the swing amplitude and frequency of the rocker, thereby ensuring the stability and consistency of the swing motion. Especially for the application scenario of the present application, the various control parameters of the swing cylinder can be accurately set for different premature babies to achieve personalized settings.

[0019] Preferably, as an improvement, the rocker is an electric push rod or a cylinder, the piston rod of the electric push rod or the cylinder is a push rod, and the piston in the milk cavity is pushed to move by the extension and retraction of the piston rod.

[0020] Beneficial effects: When sucking training is needed, the movement of the rocker drives the entire training nipple to swing, thereby stimulating the premature infant's palate and oral tissues to cause sucking; when the sucking training is completed, the piston rod is started to retract and the piston rod is used to push the piston in the milk cavity to push the milk in the milk cavity into the premature infant's mouth, inducing swallowing.

[0021] Preferably, as an improvement, a preheating interlayer is further provided outside the milk cavity of the training nipple, a heating element and a temperature sensor are provided inside the preheating interlayer, and the temperature sensor is electrically connected to the controller.

[0022] Beneficial effect: By providing a preheating interlayer and a heating element in the preheating interlayer, the training nipple and the milk in the milk cavity can be preheated, the stimulation caused by the temperature difference can be reduced, and a more realistic breastfeeding environment can be simulated.

[0023] Preferably, as an improvement, a receiver is provided at the end of the training pacifier close to the main body, and a transmitter is provided at the corresponding position of the main body, and when the receiver and the transmitter are in contact, the heating element and the temperature sensor are wirelessly powered; when the temperature sensor detects that the temperature of the training pacifier reaches a preset value, a signal is sent to the controller, and the controller controls the rocker to perform a rocking motion.

[0024] Beneficial effects: By adopting wireless contact charging technology, when the training pacifier is installed on the main body, the heating element and temperature sensor on the training pacifier can be powered through the main body, so that the training pacifier can be preheated by using the heating element; when the temperature sensor detects that the preheating temperature reaches the preset value, the controller controls the movement of the joystick, and can also serve as an indication and guidance for medical staff, prompting that the preheating temperature has been reached and sucking training can be carried out. At this time, you only need to put the training pacifier into the premature baby's mouth.

[0025] Preferably, as an improvement, an extrusion piece is detachably provided in the connecting hole, a through hole is provided on the extrusion piece, a connecting tube is provided on the top of the rocker arm, the connecting tube is slidably connected to the through hole of the extrusion piece, and when the rocker arm swings to one side, an extrusion force is applied to the extrusion piece, so that the bottom of the extrusion piece is deformed and extends out of the connecting hole to be located in an initial gap formed by the training nipple and the main body, which is used to push the training nipple to separate from the main body, so that the initial gap between the main body and the training nipple becomes a avoidance gap, so that the training nipple and the rocker arm swing together.

[0026] Beneficial effects:

[0027] 1. When the training nipple is installed on the main body, since the electronic control components on the training nipple need to be powered, the end of the training nipple needs to contact the main body, so the initial gap between the two is very small, so that the training nipple cannot swing left and right; when the preheating temperature reaches the set value, the controller controls the movement of the rocker. At this time, since the initial gap between the training nipple and the main body is very small, the rocker exerts an extrusion force on the extrusion part when it swings to one side, causing its bottom to deform and extend into the initial gap, which is used to push the training nipple to separate from the main body, so that the initial gap becomes a avoidance gap. At this time, the rocker can drive the training nipple to swing together.

[0028] 2. The above settings can achieve fully automatic operation. The preparation work before use only requires injecting breast milk into the milk cavity, and then connecting the training nipple to the main body. While connecting, the contact charging technology is used to power the heating element and the temperature sensor, so as to preheat the training nipple and milk. The waiting time can also be set through the input module on the main body to set the training duration and the action parameters of the drive component; and once the preheating temperature reaches the set value, the controller controls the joystick to start swinging, and the swing of the joystick is used to separate the training nipple from the main body by a certain distance. On the one hand, automatic power off can be achieved, and on the other hand, a clearance is left to facilitate the swinging movement of the training nipple; wherein the power is cut off for the training nipple during intervention training, which can also improve the safety of the device.

[0029] 3. By arranging an extrusion piece in the connecting hole, since the extrusion piece is elastic, when it is connected to the connecting tube at the top of the rocker, it can play a certain buffering role. Compared with the rigid connection method, the training pacifier can be softer when swinging, thereby improving the comfort and safety of use.

[0030] Preferably, as an improvement, the connecting tube includes a smooth section and a rough section. When the training nipple is in contact with the main body and energized, the smooth section of the connecting tube is connected to the extrusion piece. When the controller controls the rocker to swing, the extrusion piece and the connecting tube slide relative to each other, and the rough section of the connecting tube is connected to the extrusion piece.

[0031] Beneficial effect: by setting the connecting tube into two sections, one section is a smooth section which is conducive to training the nipple and the connecting tube to slide relative to each other during extrusion, and the other section is a rough section which can increase the friction force and ensure that the connecting tube and the extrusion piece stay in the rough section after relative sliding occurs.

[0032] Preferably, as an improvement, the extrusion piece is an airbag or silicone, and the bottom of the extrusion piece is set to an arc structure. When the rocker swings to one side, the arc structure is squeezed, causing the arc structure to bulge outward to push the extrusion piece and the connecting tube to slide relative to each other.

[0033] Beneficial effects: the airbag or silicone has good elasticity, and is easier to deform after being squeezed; setting the bottom of the extrusion piece as an arc structure makes it easier for it to deform toward the convex side of the arc, which is beneficial for separating the training nipple from the main body during squeezing.

[0034] Preferably, as an improvement, an elastic member is further provided in the extrusion member, and the elastic member is an arc-shaped structure, and the arc-shaped structure faces the outside of the training nipple. When the rocker swings to one side, the elastic member is squeezed, and the elastic member is deformed so that the arc-shaped structure extends out of the training nipple to push the extrusion member and the connecting tube to slide relative to each other.

[0035] Beneficial effect: The elastic member can be provided to further assist in generating a squeezing force, thereby separating the training nipple from the main body and forming a clearance gap between the two. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Embodiment 1

[0048] Sucking and swallowing sequence training device for premature infants, such as Figure 1 As shown, it includes a main body 2 and a training pacifier 1 detachably connected to the main body 2. The training pacifier 1 is made of food-grade silicone used to make pacifiers. The main body 2 can be set in the shape of a milk bottle for easy handholding. Figure 2-3 As shown, the main body 2 is provided with a controller 3, a power supply 4 and a driving mechanism electrically connected to the controller 3 for driving the training pacifier 1 to move, the driving mechanism includes a rocker 51 and a push rod 52, the push rod 52 is slidably arranged in the rocker 51, and the power output end of the push rod 52 extends out of the rocker 51, and the free end of the rocker 51 extends out of the main body 2 and is connected to the training pacifier 1; specifically, a connecting hole is provided at the rear end of the training pacifier 1, and the rocker 51 is connected to the connecting hole through it.

[0049] In this embodiment, the controller 3 and the power supply 4 are arranged at the bottom of the main body 2, and the driving mechanism is arranged at the upper part of the main body 2. Specifically, the upper part of the main body 2 is provided with an installation cavity 21, and the bottom of the installation cavity 21 is provided with a swing cylinder 6, which is electrically connected to the controller 3 and the power supply 4. The output end of the swing cylinder 6 is fixedly connected to the connecting shaft 61 through a key, and the other end of the connecting shaft 61 is rotatably connected to the side wall of the installation cavity 21. The bottom of the rocker 51 is fixedly connected to the connecting shaft 61 through a bolt, and the connecting shaft 61 is driven to rotate by the swing cylinder 6, thereby driving the rocker 51 to swing in the installation cavity 21; more preferably, the rocker 51 in this embodiment can adopt an electric push rod or a cylinder, and the piston rod of the electric push rod or the cylinder is used as the push rod 52. In this embodiment, a dustproof cloth can also be arranged on the top of the installation cavity 21, and the dustproof cloth is used to close the installation cavity 21. The specific dustproof cloth is an elastic cloth, so that it will not block the normal swing of the rocker 51.

[0050] like Figure 4As shown, a milk cavity 11 is provided in the training nipple 1, and a piston 111 is slidably and sealedly provided in the milk cavity 11. Specifically, the cavity wall of the milk cavity 11 can be made of a transparent hard material, so that the piston 111 can slide and seal in the milk cavity 11. The rear end of the milk cavity 11 is connected to the connecting hole. When the rocker 51 is connected to the connecting hole, the push rod 52 extends into the milk cavity 11 to push the piston 111 to slide. The front end of the training nipple 1 is also provided with an injection head 112, which is connected to the milk cavity 11. Before use, the required amount of milk can be injected from the injection head 112 into the milk cavity 11 through a syringe. When swallowing training is required, the controller 3 is used to control the push rod 52 to retract and retract, thereby pushing the piston 111 to slide in the milk cavity 11, and milk is injected from the injection head 112 to the middle and rear area of ​​the premature infant's tongue to induce swallowing.

[0051] like Figure 5 As shown, the outer surface of the main body 2 is also provided with an input module 31 and a display module 32 which are electrically connected to the controller 3. Figure 2 As shown, the input module 31 can be a keyboard 311 or a touch screen, and the display module 32 is a display screen 322, which is used to display information such as the time and action frequency of sucking training and swallowing training. The input module 31 is used to input training items in advance, and the training items include sucking training and swallowing training. After setting the training plan, the input module 31 sends the training items to the controller 3. After receiving the signal, the controller 3 first controls the rocker 51 to perform sucking training. When the sucking training reaches the preset time, the push rod 52 is controlled to inject milk according to the preset milk injection frequency to perform swallowing training.

[0052] like Figure 5 As shown, the controller 3 is also provided with a communication module 34 and an alarm module 33. The communication module 34 can be connected by Bluetooth or Wifi, and the alarm module 33 can be an audible and visual alarm or a voice alarm. The communication module 34 is wirelessly connected to an oximeter, which can be an existing fingernail oximeter, and is worn on the finger of a premature infant. When the oximeter detects abnormal data, it sends a signal to the controller 3. After receiving the signal, the controller 3 immediately controls the driving mechanism to stop the action and controls the alarm module 33 to sound an alarm. In this embodiment, the communication module 34 can also be connected to an electrocardiogram monitor. When the heart rate of the premature infant drops, a signal is sent to the controller 3, and the controller 3 immediately stops the intervention training.

[0053] like Figure 4As shown, in order to preheat the training nipple 1, reduce temperature difference stimulation, and provide a more realistic simulated training environment, a preheating interlayer 12 is further provided outside the milk cavity 11 of the training nipple 1 in this embodiment, and a heating element 121 and a temperature sensor 122 are provided in the preheating interlayer 12, and the temperature sensor 122 is electrically connected to the controller 3; specifically, the heating element 121 can be heated by an electric heating wire or infrared rays, and when the temperature sensor 122 detects that the heating temperature is 37°C, a signal is sent to the controller 3, and the controller 3 controls the heating element 121 to stop heating.

[0054] like Figure 6 As shown, a receiver 13 is provided at the end of the training nipple 1 close to the main body 2, and a transmitter 131 is provided at the corresponding position of the main body 2. When the receiver 13 and the transmitter 131 are in contact, the heating element 121 and the temperature sensor 122 are wirelessly powered. The above technology adopts the existing contact charging technology, which will not be repeated here; the advantage of such a setting is that when the training nipple 1 is installed on the main body 2, it can be powered on, so as to preheat the training nipple 1. More preferably, a groove can be provided on the main body 2, the transmitter 131 is provided in the groove, a bump is provided at the corresponding position of the training nipple 1, and the receiver 13 is provided on the bump. By providing the groove and the bump to cooperate with each other, the purpose of rapid positioning can be achieved, which is convenient for rapid installation and positioning.

[0055] In this embodiment, a squeeze piece 7 is detachably provided in the connection hole of the training nipple 1. Specifically, the squeeze piece 7 can be threaded or tensioned with the connection hole, so that the squeeze piece 7 can be removed when the training nipple 1 needs to be cleaned, and then the piston 111 in the milk cavity 11 is taken out from the connection hole, so as to clean the inside of the milk cavity 11. Specifically, a through hole 71 is provided on the squeeze piece 7, and a connecting tube 8 is provided on the top of the rocker 51. The connecting tube 8 is slidably connected with the through hole 71 of the squeeze piece 7. When the rocker 51 swings to one side, an extrusion force is applied to the squeeze piece 7, so that the bottom of the squeeze piece 7 is deformed and extends out of the connection hole to be located in the initial gap formed by the training nipple 1 and the main body 2, so as to push the training nipple 1 to separate from the main body 2, so that the initial gap between the main body 2 and the training nipple 1 becomes a clearance gap, so as to facilitate the training nipple 1 to swing together with the rocker 51.

[0056] When the training nipple 1 is mounted on the main body 2, since the electric control components on the training nipple 1 need to be powered, the end of the training nipple 1 needs to be in contact with the main body 2, such as Figure 6As shown, the training nipple 1 and the milk in the milk cavity 11 are preheated. At this time, the initial gap between the end of the training nipple 1 and the main body 2 is very small, and the training nipple 1 cannot swing left and right; when the temperature sensor 122 detects that the temperature of the training nipple 1 reaches a preset value, a signal is sent to the controller 3, and the controller 3 controls the rocker 51 to move. At this time, since the initial gap between the training nipple 1 and the main body 2 is very small, the training nipple 1 cannot swing therewith. When the rocker 51 swings to one side, an extrusion force is applied to the extrusion member 7, causing the bottom of the extrusion member 7 to deform and extend into the initial gap, thereby being used to push the training nipple 1 to separate from the main body 2, as shown in FIG. Figure 7 As shown, the initial gap becomes an avoidance gap, and at this time the rocker 51 can drive the training nipple 1 to rock together.

[0057] In this embodiment, in order to further facilitate the relative sliding of the extrusion member 7 and the connecting pipe 8, as shown in FIG. Figure 2 As shown, the connecting tube 8 is provided with a smooth section 81 and a rough section 82. When the training nipple 1 is in contact with the main body 2 and energized, the smooth section 81 of the connecting tube 8 is connected to the extrusion piece 7. When the controller 3 controls the rocker 51 to swing, the bottom of the extrusion piece 7 is extended, thereby pushing the extrusion piece 7 and the connecting tube 8 to slide relative to each other, thereby making the rough section 82 of the connecting tube 8 connected to the extrusion piece 7. The smooth section 81 is conducive to the relative sliding of the training nipple 1 and the connecting tube 8, and the rough section 82 is conducive to increasing the friction force, thereby ensuring that the connecting tube 8 stays in the rough section 82 after the relative sliding of the extrusion piece 7.

[0058] Preferably, the extrusion member 7 of this embodiment can be made of airbag or silicone, which has good elastic deformation force, so that it is easy to deform and stretch out after extrusion; further, Figure 4 As shown, the bottom of the extrusion piece 7 can also be set as an arc-shaped structure 72, and the convex side of the arc-shaped structure 72 faces the outside of the training nipple 1, so that it has a tendency to deform outward. When the rocker 51 swings to one side, the arc-shaped structure 72 is squeezed, so that the arc-shaped structure 72 is better deformed and extended outward, thereby pushing the extrusion piece 7 and the connecting tube 8 to slide relative to each other.

[0059] This embodiment also provides a method for training the sucking and swallowing sequence function of premature infants:

[0060] Step 1, preparation stage: first, select the appropriate amount of breast milk according to the situation of the premature baby, and use a syringe to inject it from the injection head 112 of the training pacifier 1; then, set the time, action frequency and other parameters of sucking training and swallowing training through the input module 31 on the main body 2; after preparation, install the training pacifier 1 on the main body 2, so that the receiver 13 on the training pacifier 1 is in contact with the transmitter 131 on the main body 2 to achieve contact wireless charging. At this time, the heating element 121 starts to preheat the training pacifier 1 and milk. When the preheating temperature reaches the set value, the temperature sensor 122 sends a signal to the controller 3, and the controller 3 automatically controls the rocker 51 to move, so that the training pacifier 1 is separated from the main body 2.

[0061] Step 2, sucking training: when the training nipple 1 is separated from the main body 2 to form a clearance, the training nipple 1 is placed in the premature infant's mouth. At this time, the controller 3 controls the swing cylinder 6 to operate at a preset frequency, thereby driving the connecting shaft 61 to rotate. The rotation of the connecting shaft 61 drives the rocker 51 to swing. The swing of the rocker 51 drives the training nipple 1 to swing, thereby stimulating the premature infant's oral tissue, especially the hard palate, thereby inducing a sucking action. The training duration can be set to 3-5 minutes.

[0062] Step 3, swallowing training: when the sucking training reaches the set time, the controller 3 controls the swing cylinder 6 to stop moving, and the rocker 51 is in a vertical state; the controller 3 starts to control the push rod 52 to extend and push the piston 111 to move, and pushes the piston 111 a certain distance each time according to the preset frequency, so that the milk in the milk cavity 11 is squeezed out from the injection head 112; more preferably, one drop of milk is pushed into the middle and rear area of ​​the premature baby's tongue each time, thereby stimulating swallowing and inducing swallowing action.

[0063] The above training method can be intervened 2-4 times a day according to the situation, each time for 5-10 minutes. The heart rate and blood oxygen saturation of premature infants are monitored throughout the training. Once an abnormality occurs, the controller 3 immediately controls the drive mechanism to stop the action and sounds an alarm. Medical staff immediately check the training situation to ensure safety of use.

[0064] Embodiment 2

[0065] The difference between this embodiment and the first embodiment is that Figure 8 As shown, the connecting hole and the extrusion piece 7 are eccentrically arranged, and the extrusion piece 7 is an airbag. When the airbag is expanded, it is an annular structure. When it is not expanded, the annular structure of the inner circle of the airbag is closed to form a strip-shaped gap 73. At this time, the entire connecting hole can be closed to ensure the cleanliness of the rear end of the milk cavity 11; Fig. 9As shown, when the connecting tube 8 on the rocker 51 is inserted into the strip-shaped gap 73, the strip-shaped gap 73 gradually opens to become a cylinder, and at this time the airbag is a ring-shaped structure that is tightly held on the connecting tube 8 for sliding connection with the connecting tube 8. In this embodiment, since the connecting hole and the extrusion piece 7 are eccentrically arranged, the airbag area on one side is larger than that on the other side. When the rocker 51 starts to swing and squeezes the airbag on the side with a larger area, the airbag is more likely to deform and extend out of the connecting hole, thereby pushing the training nipple 1 to separate from the main body 2, and forming a clearance gap between the two.

[0066] Embodiment 3

[0067] The difference between this embodiment and the first embodiment is that an elastic member (not shown in the figure) is further provided in the extrusion member 7, the elastic member is arc-shaped, and the convex side of the arc faces the outside of the training nipple 1. When the rocker 51 swings to one side, the elastic member is squeezed, and the elastic member is deformed so that the arc 2 extends out of the training nipple 1, which is used to assist in pushing the extrusion member 7 and the connecting tube 8 to slide relative to each other; specifically, the elastic member can be an elastic sheet, and the provision of the elastic member can further assist in generating an extrusion force, thereby separating the training nipple 1 from the main body 2, and forming a clearance gap between the two.

[0068] Embodiment 4

[0069] The difference between this embodiment and the first embodiment is that it also includes a robotic arm (not shown in the figure). The robotic arm is a prior art and will not be described in detail here. When in use, the robotic arm can be set next to the monitoring bed and connected to the main body 2. The main body 2 is clamped by the robotic arm, which can free both hands. Medical staff only need to monitor at the side during training.
