Description

Technical Field

[0001] The invention belongs to the field of medical instruments and equipment, and relates to a premature infant sucking force detection and training device and a use method thereof. Background Art

[0002] In recent years, the incidence of premature birth has been on the rise. Providing adequate and balanced nutrition is a key factor in improving the survival rate of premature infants and their quality of life. Pursuing safe and effective oral feeding is the goal of nutritional management for premature infants. Oral feeding refers to the autonomous sucking and feeding of infants. This is a highly complex activity that requires the cooperation of multiple systems such as nerves and muscles. When sucking and feeding, multiple parts such as lips, cheeks, mandibles, and tongue participate in the action. However, affected by various factors of premature birth, many premature infants cannot form coordinated sucking, swallowing, and breathing movements. Objectively and accurately testing the sucking force of premature infants and the facial muscle movements during sucking is a prerequisite for guiding premature infants to exercise oral feeding. However, there is currently no equipment that can detect the sucking force of premature infants and the changes in facial muscles during sucking, and there is no device that can perform reasonable sucking force training based on the sucking force and facial muscle changes of premature infants, which is not conducive to cultivating good oral feeding in premature infants. Summary of the invention

[0003] The purpose of the present invention is to address the problems in the prior art that there is no device for detecting the sucking force of premature infants and the degree of change of facial muscles during sucking and to conduct reasonable sucking force training based on the detection results, which is not conducive to the premature infants to exercise good oral feeding. A premature infant sucking force detection and training device and its use method are proposed. The device and use method of the present invention can detect the sucking force of premature infants and the degree of change of facial muscles during sucking, and conduct reasonable sucking force training for premature infants based on the inspection results, so as to help premature infants improve their sucking force and facilitate the premature infants to form good oral feeding.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] A sucking force detection and training device for premature infants comprises a control host, a sucking force sensing training bottle, a sucking action sensor and a control system; an arc cover matching the sucking force sensing training bottle is arranged beside the control host; a signal line is connected between the sucking action sensor and the control host; the front end of the sucking force sensing training bottle is connected to a sensing training part, and the front end of the sensing training part is connected to a nipple; the nipple is connected to a milk suction hose; the milk suction hose passes through the sensing training part and then passes into the bottom of the sucking force sensing training bottle; a sucking force sensor is arranged in the milk suction hose; a wireless signal transceiver module and an ARM processor are also arranged in the sensing training part; a cam is arranged in the sensing training part; the cam is connected to a motor; The cam is located below the milk suction hose; the wheel surface of the cam sticks to the milk suction hose; at least three groups of sucking action sensors are provided; two groups of sucking action sensors correspond to the zygomatic positions on both sides of the premature infant respectively, and the third group of sucking action sensors corresponds to the chin position of the premature infant; the three groups of sucking action sensors are all connected to the control host through signal lines; the three groups of sucking action sensors are all provided with distance sensing modules, which can sense the changes in the position distance of each other; the control system is arranged in the control host; the control system includes a calculation module, a wireless signal processing module, a data storage module and a milk bottle milk discharge control module; the control host is also provided with an operation display screen; the wireless signal processing module is connected with a filter module.

[0006] The arc cover is placed in a matching position to place a sucking force induction training bottle; the sucking action sensor is used to detect the degree of chin movement when the premature baby sucks, so as to judge the movement amplitude of the facial muscles when sucking. The larger the chin movement amplitude, the greater the change in facial muscles and the better the sucking action; three groups of branches are separated from the front end of the signal line, which are respectively connected to the three groups of sucking action sensors; the nipple at the front end of the induction training part is used for premature babies to suck; the milk suction hose extends into the body of the sucking force induction training bottle, which is used for premature babies to suck through the milk in the bottle; the sucking force sensor is used to sense the sucking force of premature babies when sucking milk; the wireless signal transceiver module in the induction training part is used to wirelessly transmit the detected sucking force information to the control host and receive the control information of the control host at the same time; the wireless signal transceiver module can be a Bluetooth module; the ARM processor is used to control the motor to drive the cam to rotate; a rechargeable battery is also provided in the control induction training part to provide power for the electrical appliances in the control induction training part; the motor can drive the cam to rotate, when the cam is longer than half When one side of the diameter is turned to the position of contacting the milk suction hose, the milk suction hose is squeezed to reduce the amount of milk passing through. After a premature baby can suck a certain amount of milk after several suckings, if it suddenly cannot suck milk, it will instinctively increase the sucking force, so that the instinct drives the premature baby to exercise the sucking force. The sucking action sensor is provided with a medical adhesive patch, which can be attached to the skin of the premature baby. Through the position changes of the sucking action sensor at the chin position and the sucking action sensor at the zygomatic position, the degree of change of the facial muscles of the premature baby when sucking can be obtained, and whether the sucking action is good can be judged. The calculation module of the control system is used to calculate and compare the change of the sucking force of the premature baby and the change of the face during sucking, and form a chart; the wireless signal processing module is used to receive the sucking force detection information sent by the induction training unit, and transmit it to the calculation module at the same time, and send the information of the bottle milk discharge control module to the induction training unit to control the motor; the data storage module is used to store data; the display screen is used to display the detection data; the filtering module is used to filter clutter, so that the calculation module can receive more accurate detection data information.

[0007] As a further technical improvement, a force-bearing top plate is provided in the induction training part; the force-bearing top plate is located above the milk suction hose and is attached to the milk suction hose. The force-bearing top plate supports the top of the milk suction hose, so that the cam can flatten the milk suction hose when squeezing the lower part of the milk suction hose, thereby reducing the amount of milk passing through.

[0008] As a further technical improvement, the control host is provided with a base at the bottom; the base is provided with a bottle slot; the bottle slot matches the bottom of the sucking force induction training bottle; the arc cover is arranged at the edge of the bottle slot. The bottle slot is used to place the induction training bottle.

[0009] As a further technical improvement, the arc cover and the bottle slot are both provided with electric heating wires; the electric heating wires are connected to the control host. The electric heating wires are used to heat the induction training bottle to make the milk temperature suitable; the electric heating wires are connected to the control host, and the heating temperature can be adjusted by the control host.

[0010] As a further technical improvement, the motor is a stepper motor; the motor is connected to an angle sensor; the angle sensor is connected to the ARM processor in the induction training unit. The angle sensor can detect the angle of the motor rotation, so as to determine the degree of the cam squeezing the milking hose; in the initial state, the shortest radius side of the cam contacts the milking hose, and the milking hose is not squeezed at this time; as the cam rotates, the milking hose is gradually squeezed, and when the motor drives the cam to rotate 90°, the longest radius side of the cam contacts the milking hose, and the milking hose is squeezed to the maximum extent at this time, so the degree of squeezing the milking hose by the cam can be determined and controlled by detecting the angle of the motor rotation through the angle sensor; if the premature baby's sucking force is insufficient, but relatively large, the degree of squeezing the milking hose by the cam can be appropriately increased, so that the premature baby can suck harder if the premature baby can reach it, so as to better exercise the premature baby's sucking force, otherwise the cam is controlled not to squeeze the milking hose too much.

[0011] As a further technical improvement, a wire receiving groove is provided on the side of the control host; a wire releasing opening is provided on one side of the wire receiving groove. The wire receiving groove is used to receive the signal wire connected to the sucking action sensor; and the wire releasing opening is used to put the signal wire into the wire receiving groove.

[0012] As a further technical improvement, the control host is also provided with a control button which is used to control the start and stop of the device and various parameter settings.

[0013] As a further technical improvement, a gravity ball is provided at the bottom of the milk suction hose, which can transform the sucking force induction training bottle into a gravity cup, thereby facilitating the sucking of milk.

[0014] As a further technical improvement, the induction training part is detachably connected to the body of the sucking force induction training bottle; the nipple and the milk suction hose are both detachable. The induction training part and the body of the sucking force induction training bottle can be connected in the form of a threaded connection; the nipple and the milk suction hose are both detachable for easy cleaning.

[0015] The method for using the above-mentioned premature infant sucking force detection and training device comprises the following steps:

[0016] Sucking force detection: put milk in the sucking force sensing training bottle and provide the nipple for the premature baby to suck; during the sucking process, the sucking force sensor in the sucking hose senses the sucking force of the premature baby and transmits the sensed sucking force information to the control host through the wireless signal transceiver module; every time the premature baby sucks milk, the control host records it as a sucking pulse;

[0017] Detection of sucking action: stick two sets of sucking action sensors on the corresponding parts of the cheekbones of the premature infant; stick the remaining set of sucking action sensors on the chin of the premature infant; in each sucking pulse of the premature infant, the relative positions of the sucking action sensors corresponding to the cheekbones remain unchanged, and as the premature infant's mouth moves, the position between the sucking action sensors on the chin and the sucking action sensors on the cheekbones changes and is detected; the distances between the sucking action sensors on the chin and the two sets of sucking action sensors on the cheekbones are set to S1 and S2 respectively, and transmitted to the control host through the signal line at the same time, so as to reflect the premature infant's mouth movement when sucking milk;

[0018] Sucking force training: The control host receives and records the sucking force of the premature baby in each sucking pulse and the changes in S1 and S2. When the premature baby's sucking force is small or the values ​​of S1 and S2 are low, it means that the premature baby's sucking force is insufficient, and the control host issues an alarm; the medical staff starts the sucking force training according to the alarm information; during the sucking force training, the motor does not rotate in at least two sucking pulses, and the milk suction hose is not squeezed at this time, so the premature baby can drink milk smoothly; in the next sucking pulse, the motor drives the cam to rotate, so that the side with a longer radius of the cam turns to the milk suction hose, thereby squeezing the milk suction hose; the premature baby can normally suck more milk in the previous sucking process, but at this time, because the milk suction hose is squeezed, it needs to use a greater sucking force to suck out enough milk, so as to achieve the premature baby's independent training of sucking force; the interval of the cam squeezing the milk suction hose can be set by the medical staff, and can also be set to random squeezing;

[0019] Data collection: The control host records and saves the data of the premature infant's sucking force each time he sucks milk, the changes in the mouth movement during the sucking action, the sucking duration and the number of sucking force training times, and forms a chart of the data changes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can detect the sucking force of premature infants when sucking milk through the sucking force sensing training bottle, and send the detection result to the control host, which is conducive to evaluating the current sucking force of premature infants and guiding subsequent sucking force improvement training, helping premature infants to establish good oral feeding.

[0022] 2. The present invention can sense the movement amplitude of the premature infant's chin when sucking milk through the sucking action sensor, thereby obtaining the movement changes of the facial muscles during sucking, thereby judging whether the premature infant's sucking action is good, and guiding the subsequent sucking force improvement training of the premature infant.

[0023] 3. The present invention controls the amount of milk that a premature infant can suck by means of a motor driving a cam to rotate, thereby squeezing a milk suction hose, and suddenly squeezing the milk suction hose after the premature infant can suck relatively more milk, so that the premature infant instinctively increases the sucking force, allowing the premature infant to exercise the sucking force independently.

[0024] 4. The control host of the present invention can record the sucking force of premature infants and the amplitude of the jaw movement during sucking, and form a chart to help medical staff understand the changes in the sucking force and sucking movement of premature infants and guide the subsequent care and treatment of premature infants.

[0025] 5. The electric heating wire of the present invention can heat the sucking force induction training bottle to keep the temperature of the milk in the bottle moderate, which is conducive to the premature infant's sucking. BRIEF DESCRIPTION OF THE DRAWINGS
