Description

Premature infant rehabilitation training system capable of realizing remote cooperation

Technical Field

The embodiment of the disclosure relates to a premature infant rehabilitation training system capable of realizing remote cooperation, in particular to a medical instrument which is used by a medical institution for training and improving the health level of a premature infant.

Background

Premature infants (also called immature infants) refer to live-birth infants born before 37 weeks of gestational age, and the birth weight of the infants is mostly below 2.5kg, and the head circumference is below 33 cm. Premature infants have a number of health problems, such as central nervous system dysplasia, slow response to sensory stimuli, poor tonometric reflex; the coordination function of sucking, swallowing and breathing is poor, and the feed can not be fed orally, which is easy to cause feeding difficulty. Also, premature babies are usually isolated after birth by low mid-frequency current migration into the NICU, resulting in increased anxiety and even depressed mood in many premature parents. Moreover, isolation therapy lacks the familiar voice of the mother, reduces the sense of safety of premature infants, and is not beneficial to the development and recovery of premature infants.

Many premature infants exhibit low self-regulating abilities, resulting in reduced behavioral alertness. For the rehabilitation of premature infants, intervention is carried out through various medical means such as sensory stimulation, the development level of a nervous system, the sucking and swallowing capacity are improved, and oral feeding is realized as soon as possible. Intervention in the sense of hearing, touch, etc. of premature infants helps to promote the development of behavioural tissue and nervous system. Medical science has proved that sensory stimulation such as body stroking, oral muscle massage and finger sucking is carried out on the premature infant, which is helpful for improving the oral motion ability of the premature infant and accelerating the process of oral feeding. The premature infant can listen to the sound familiar to the parents, stop crying and screaming and recover to a quiet state, so that the development of the premature infant is facilitated. However, at present, the intervention means are highly dependent on manual development, are limited by insufficient manpower configuration of NICU medical care personnel, and control measures of an NICU ward on hospital infection sources are adopted, so that parents are prevented from accompanying, and various sensory stimuli can not be effectively implemented for premature infants. Therefore, the embodiment of the disclosure provides a rehabilitation training system for implementing intervention in multiple modes such as touch, taste, hearing and the like, and fills the blank of the technical field.

The control mainboard is an integrated circuit developed based on a core processor, and the control mainboard also comprises general elements such as a signal processing module, a storage module and the like. The core processor is usually any one of a Central Processing Unit (CPU), a Programmable Logic Controller (PLC), or a single chip Microcomputer (MCU). The control mainboard is burned with embedded software which is mainly used for mainboard driving, data processing, data analysis, program control, parameter setting, information printing output and other functions.

The somatosensory stimulation unit mainly comprises a power device and an elastic prosthesis, wherein the elastic prosthesis is arranged at the front end of the somatosensory stimulation unit, and the elastic prosthesis generates rhythmic stimulating actions under the action of the power device. For example, the power device drives the elastic prosthesis to generate vibration, touch, scratching or zooming actions and the like for stimulating the oral cavity or the body of the newborn baby. According to the type of the stimulating action, the power device selects one or a combination of a micro vibration motor, a stepping motor, a servo motor or a micro air pump. The elastic prosthesis can be made of medical polymer materials such as latex or silica gel and the like, and is prepared into bionic shapes similar to fingers, nipples and the like, and the elastic prosthesis is usually used for one time. For example, the elastic prosthesis is prepared into a finger shape, and in the specific clinical application of the somatosensory stimulation unit, the servo motor drives the finger-shaped elastic prosthesis to rhythmically scratch, poke and vibrate at a low frequency, so that the inner muscles or lips of the oral cavity of the premature infant are stimulated, and the oral cavity development of the premature infant is promoted. For another example, the elastic prosthesis is prepared into a hollow bionic nipple shape, and the power device adopts a micro air pump; the hollow nipple base is connected with an air path interface of the micro air pump by adopting an extension pipe; the micro air pump performs rhythmical suction action on the inside of the bionic nipple through alternate actions of inflation and deflation, so that the bionic nipple performs rhythmical expansion, maintenance and contraction actions. When somatosensory stimulation training is carried out, the bionic nipple is placed into the oral cavity of the premature infant, and the expansion, the maintenance and the contraction of the bionic nipple are alternated in a rhythmic manner to stimulate the muscles or the tongue inside the oral cavity of the premature infant and promote the development of the oral cavity movement function.

The pressure sensor is used for dynamically measuring the negative pressure value generated in the oral cavity in the process of sucking the premature infant, and a high-precision small-range pressure sensor is adopted, the range is not less than-35KPa to 0, and the precision is not less than 0.1KPa. The special consumable is a sanitary material matched with the taste stimulation unit for use, is used for feeding training of liquid food and is usually disposable.

According to the personalized characteristics of the premature infant, the medical staff sets a stimulation training target value of the premature infant, the stimulation training target value is set between negative pressure of sucking-5 KPa to-10 KPa, and the flow controller controls the dynamic release of liquid food (such as milk or honey water) according to the set stimulation training target value to stimulate the sucking action reaching the training target value with taste sense. For example, when the milk is used for carrying out gustation stimulation training on the premature infant, the stimulation training target value is set to be-8 KPa, the feeding pipeline is arranged on the periphery of a peristaltic pump of the flow controller, and the bionic nipple is arranged in the oral cavity of the premature infant to induce the premature infant to generate the sucking action. When the suction negative pressure of the premature infant reaches-8 KPa, the peristaltic pump extrudes the feeding pipeline to convey milk to the bionic nipple, the milk flows into the oral cavity of the premature infant, the premature infant is stimulated to continuously try to suck by releasing the milk, and the suction capacity of the premature infant is stimulated to be improved. After the set stimulation training target value is completed, the training target value can be increased stepwise, and taste stimulation training is repeated until the premature infant can be fed through the mouth completely.

The audio collector and the sound device of the remote interaction unit can be arranged independently, and preferably, the audio collector and the sound device are shared with the auditory stimulation unit. The remote interaction unit is used for interactive communication between the medical care end and the incubator end, or interactive communication between the parent end of the premature infant and the incubator end, or three-party interactive communication between the medical care end/the incubator end/the parent end of the premature infant. For example, the remote interaction unit is started, and through the authorization and identity confirmation of medical staff, the premature infant parents can remotely watch the state of the premature infant in the incubator end through a mobile phone or a computer of the premature infant parents, and the voice of the premature infant can be synchronously transmitted to the premature infant.
