Description

Detecting device for automatic feeding machine for premature infant

Technical Field

The present invention relates to medical equipment, and is especially one kind of automatic premature infant nursing machine detecting device.

Background

In the current process of women's production, it is difficult to avoid premature babies which may be produced due to various physiological phenomena. Since the development of premature infants is not fully sound, the function of sucking liquid nutrition such as milk through the mouth is not sound, and therefore, the premature infants are generally guided into the stomach by a stomach tube for absorption and digestion. Therefore, some members of the present invention have developed "automatic premature infant nursing method and automatic nursing machine", and applied for the chinese patent invention (application No. 201811279307), and the abstract of the present application outlines "an automatic premature infant nursing method, including a preparation phase, an active milk supply phase, a passive milk supply phase and a rest phase; the invention also provides an automatic nursing machine adopted by the automatic nursing method for the premature infant, which comprises a stomach tube, a milk supply device, a detector and a control device, wherein one end of the stomach tube is arranged in the stomach of the premature infant, the other end of the stomach tube is connected with the milk supply device, the milk supply device is electrically connected with the control device, the control device is electrically connected with the detector, and the detector is arranged in the mouth of the premature infant; the invention trains the self-sucking ability of the premature infant, and makes the mouth-pharynx-stomach-intestine of the premature infant reflect normal circulation, and guarantees the nutrition requirement of the premature infant under the condition of considering the difference of the premature infant, thereby making the premature infant have no difference with the term infant in the aspects of nursing, diet, nerve development and growth development in the future. "in this case, the probe includes a suction nozzle and a pressure sensor disposed in the suction nozzle, and the pressure sensor is electrically connected to the control device. When the premature infant sucks the detector again, the detector acquires the sucking action of the premature infant, converts the sucking action into a sucking signal and transmits the sucking signal to the control device, the control device starts the milk supply device after receiving the sucking signal, and the milk supply device stops supplying milk to the premature infant through the stomach tube after supplying a certain amount of milk.

Further, as discussed with respect to the probe, the principle of Strain (Strain) is to detect the change of the length of the object relative to the original length, and the deformation of the object is caused by the applied force. The pressure sensor of the prior art mainly detects the change ratio of the length generated by the suction nozzle (object) relative to the length in the non-sucking state to detect the force applied by the premature infant to suck. The basic principle of this detection is that the resistance of the object itself will vary with the total amount of applied force (Strain), such as a Bonded Metallic Strain Gauge (Bonded Metallic Strain Gauge), which must use high-precision Grid lines (Grid) arranged in parallel and electronic, circuit, etc. operation and logic elements. As such, the prior art pressure strain gauges are expensive due to the precision of the components. However, since the sucking action reflected by hunger of a premature infant is a physiological phenomenon, it is often only necessary to know whether the infant is sucking, and thus the pressure sensor used does not necessarily need such a highly precise instrument. Therefore, the research and development members (the same as the research and development members in the prior art) think of whether the technology capable of changing the physical detection condition or phenomenon exists under the spirit of research and development without loss, so that the sucking of the premature infant can be intuitively reflected, and meanwhile, the material cost is saved and the reliability is increased.

Disclosure of Invention

In view of the problems of the prior art, the present invention provides a detecting device for an automatic premature infant feeding machine, comprising a feeding tube for receiving milk, an outlet of the feeding tube being connected to a feeding hose reaching the stomach organ of the premature infant, an inlet of the feeding tube being provided with a pushing column inside, the pushing column being connected to a control device; the sucking detector is arranged additionally and used for detecting the sucking action of the premature infant, the sucking detector is electrically connected with the control device to drive the pushing column to push, the sucking detector comprises a suction nozzle and a pressure sensor arranged in the suction nozzle, the pressure sensor is electrically connected with the control device, the pressure sensor comprises a tympanic membrane type pressure sensor, the suction nozzle comprises a convex part, the tympanic membrane type pressure sensor and the peripheral wall of the convex part are enclosed together to form a closed space, when the convex part is sucked, the closed space is extruded to relatively press the inner side wall of the enclosed space, and therefore the tympanic membrane type pressure sensor can detect the pressure.

With the pressure sensor of the present invention, the force exerted by the premature infant on the infant is not detected by the ratio of the length of the nozzle (object) to the length of the nozzle in the non-sucking state. The closed space is extruded to relatively press and lift the inner side wall of the periphery, so that the tympanic membrane type pressure sensor can detect the pressure. That is, the deformation of the body of the object is detected by the suction nozzle (object) in the prior art, while the size change of the space is detected by the present invention. The invention does not need to adopt a complicated Strain Gauge (Bonded Metallic Strain Gauge), and also adopts relatively simple Grid lines (Grid) which are arranged in parallel and operation and logic elements such as electronics, circuits and the like. Therefore, the sucking action reflected by the hunger of the premature infant can be obtained, the material cost is saved, and the reliability is improved because the components are simple, the loss is low, and the price is relatively low.
