Description
Technical Field
The utility model belongs to the technical field of nutrient solution configuration technique and specifically relates to a flowing back metering device is related to.
Background
Intravenous nutrition infusion has become an important means of effective nutritional support for premature and critically ill neonates in NICU, particularly in the early postnatal period. The preparation process of the intravenous nutrient solution (TNA) for the newborn is more complicated than that of adults, the liquid requirement and energy of different body masses are different in different days, and the amount of liquid, energy, protein, fat and trace elements required by each kilogram of body mass per day must be determined according to the day age, the treatment course, the body mass and the types of diseases suffered by the newborn. The intravenous nutrient solution is prepared in an environment and equipment meeting requirements, and various components are added into the intravenous nutrient bag through a standardized preparation method for intravenous nutrient infusion of a child patient so as to maintain normal metabolism of an organism and achieve the aim of nutrient treatment.
The amount of TNA used in the newborn is very small, only dozens of milliliters or hundreds of milliliters, and the intravenous nutrient solution is prepared without using an intravenous nutrient preparation bag (the standard is 1-3L, which is not suitable for the newborn). At present, in clinical practice, a 10% glucose infusion soft bag which is not an air-dependent system is often adopted for a newborn intravenous nutrition bag. In general, 50ml of the solvent and 100ml of the solvent can be added to 200ml, and 250ml of the solvent can be added to 400 ml. The selection of a 10% glucose infusion bag is generally as follows: when the total amount of the intravenous nutrient solution is less than or equal to 200ml and the dosage of the 10 percent glucose injection is less than or equal to 60ml, selecting a bag of 50ml of 10 percent glucose injection; when the total amount of the intravenous nutrient solution is less than or equal to 200ml, the dosage of the 10 percent glucose injection is more than 60ml, and 100ml of the 10 percent glucose injection is selected; when the total amount of the intravenous nutrient solution is more than 200ml but less than or equal to 400ml, no matter how much the 10 percent glucose injection is used, 250ml of the 10 percent glucose injection is selected; the total amount of the intravenous nutrient solution is more than 400ml, no matter the dosage of the 10 percent glucose injection, 500ml of the 10 percent glucose injection is selected.
However, the daily dosage of 10% glucose solution required by each child does not always match the amount of fluid in each bag, and a nurse is often required to use a 50ml syringe to aspirate and remove excess fluid to achieve the desired dosage. Therefore, the nurse needs to repeatedly perform the puncture while the newborn infant is preparing the intravenous nutrient solution. In order to improve the working efficiency, many nurses prefer to use large-size needles for liquid drainage treatment, but when the needles penetrate through the bottle stoppers, certain rubber plug scraps can be left in the needle holes, and along with each suction and injection, the rubber plug scraps can enter the nutrient solution, so that certain pollution is caused; in the process of each suction and drainage, high requirements are placed on the sterile operation of nurses, and the phenomenon of full grasping can occur without paying attention to the nurses, so that iatrogenic pollution is caused; the puncture frequency and the incidence rate of infection are positively correlated, and the probability of pollution is increased by repeated puncture; the process of sucking and discharging liquid each time is time-consuming and labor-consuming, and the workload of clinical nurses is increased.
