Description

Technical Field

[0001] The utility model relates to the technical field of neonatology; specifically, it is a nasal feeding device. Background Technique

[0002] A neonatal nasal feeding device is a medical device specifically designed for nutritional supplementation and drug delivery into the nasal cavity of infants and neonates. A neonatal nasal feeding device usually consists of parts such as a flexible tube, a nasal feeding tube, and a reservoir, with a smaller size and a soft material to adapt to the physiological characteristics of infants and neonates. It is generally used for premature infants, low-weight infants, diseased infants, or neonates in need of additional nutritional support.

[0003] Currently, most of the existing nasal feeding devices do not have a constant temperature device. During the nasal feeding process for neonates, the nutrient solution needs to continuously flow into the neonate's stomach by gravity. During this period, the temperature of the nutrient solution may decrease, causing discomfort in the neonate's gastrointestinal tract, which is not conducive to the health of the neonate and affects the practicality of the device to a certain extent. Moreover, most of the existing nasal feeding devices do not have a movable fixing device. During the insertion of the nasal feeding tube, medical staff may need to insert the nasal feeding tube into the neonate's stomach based on experience, and then use medical tape to fix the nasal feeding tube on the neonate's face. During the operation process, the nasal feeding tube may slide inward, which is not conducive to safely intubating the neonate and reduces the safety of the device to a certain extent. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 4 shown, the present utility model provides a nasogastric feeding device, which includes a nasogastric feeding mechanism 1. The nasogastric feeding mechanism 1 includes a liquid tube 11. The nasogastric feeding mechanism 1 further includes a piston rod 12, and the outer surface of the lower end of the piston rod 12 is inserted into the center of the upper end of the liquid tube 11. And the center of the outer surface of the lower end of the liquid tube 11 is communicated with a nasogastric tube 13. A movable push block 31 is sleeved on the outer surface of the nasogastric tube 13. Scale lines are provided on the outer surface of the nasogastric tube 13 starting from the insertion end. When pushing the movable fixing mechanism 3, it is convenient to push the movable fixing mechanism 3 to a suitable position, insert the nasogastric tube 13 into the stomach of the newborn through the nasal cavity. At this time, the movable fixing mechanism 3 can just touch the position of the nasal cavity;

[0026] The constant temperature mechanism 2 includes a thermostat 21, and the thermostat 21 is sleeved on the outer surface of the lower end of the liquid pipe 11. The constant temperature mechanism 2 further includes a heating tank 22, and the heating tank 22 is arranged inside one end of the outer surface of the upper end of the thermostat 21, and the size of the heating tank 22 is adapted to the external size of the liquid pipe 11. A constant temperature heater is arranged inside the thermostat 21. The constant temperature heater is a device for controlling temperature and is usually used in medical fields, laboratories, industrial production and other fields. It can keep the heated liquid, gas or object at a constant temperature through components such as electric heating elements and constant temperature controllers. In the medical field, constant temperature heaters are usually used in operating rooms, delivery rooms, rehabilitation rooms and other places for heating infusions, warming patients, culturing bacteria, etc. Through the constant temperature heater, medical staff can accurately control the temperature of the liquid or object to ensure the comfort of patients and the treatment effect. A heating plate is arranged on the outer surface inside the heating tank 22 to heat the liquid pipe 11 at a constant temperature to ensure that the liquid flowing out from the end of the nasogastric tube 13 can be adapted by the newborn;

[0027] On the other end of the outer surface of the upper end of the thermostat 21, there is a temperature display screen 23, and on the upper end of one side outer surface of the thermostat 21, there is a fixed hook 24 fixedly connected. A temperature sensor is arranged inside the thermostat 21. The temperature of the liquid inside the liquid pipe 11 can be monitored in real time through the temperature sensor and displayed through the temperature display screen 23. The size of the fixed hook 24 is adapted to the outer wall of the newborn incubator and can be hung on the outer wall of the incubator to fix the position of the constant temperature mechanism 2.

[0028] Embodiment 2

[0029] As Figure 1 and Figure 5 shown, this embodiment also proposes:

[0030] The movable fixing mechanism 3 includes a movable push block 31, and the movable push block 31 is sleeved on the outer surface of the nasogastric feeding mechanism 1. The movable fixing mechanism 3 further includes a movable hole 32, and the movable hole 32 is opened inside the center of the outer surface of the upper end of the movable push block 31, and the inner surface of the movable hole 32 is in contact with the outer surface of the nasogastric tube 13. The outer surface inside the movable hole 32 is made of rubber. Rubber is a polymer material with high elasticity and usually comes from natural rubber or synthetic rubber. Due to its special chemical structure and physical properties, rubber has a relatively high friction coefficient and is suitable for manufacturing products and components with friction performance requirements. This utility model utilizes the high friction coefficient characteristic of rubber, so that the friction force between the movable push block 31 and the outer surface of the nasogastric tube 13 is relatively large, and it cannot move easily during the intubation process, restricting the insertion depth of the nasogastric tube 13, and only allowing medical staff to push it by hand;

[0031] On both sides of the upper end of the outer surface of the movable push block 31, connecting pieces 33 are fixedly connected. One end of the connecting piece 33 is fixedly connected with a fixing piece 34. The connecting piece 33 and the fixing piece 34 are both made of soft plastic material. After inserting the nasal feeding tube 13, bend the connecting piece 33 and the fixing piece 34 to fit the face of the newborn, and then use medical tape to fix them, so as to fix the movable fixing mechanism 3 and the nasal feeding tube 13.

[0032] Working principle: First, according to the physique of the newborn, manually push the movable fixing mechanism 3 on the outer surface of the nasal feeding tube 13 until it reaches the appropriate scale on the nasal feeding tube 13. Then insert the nasal feeding tube 13 from the nasal cavity of the newborn to the tail. At this time, the movable push block 31 is located at the nasal cavity position. Manually bend the two groups of connecting pieces 33 and the fixing piece 34 to make them fit the face of the newborn. Finally, use medical tape to fix the fixing piece 34, so as to fix the movable fixing mechanism 3 and the nasal feeding tube 13.

[0033] Subsequently, hang the fixed hook 24 on the outer wall of the incubator, draw out the piston rod 12 from the inside of the liquid tube 11, fill the inside of the liquid tube 11 with nutrient solution, then insert the piston rod 12 back, insert the liquid tube 11 into the inside of the heating tank 22, and manually connect one end of the nasal feeding tube 13 with the liquid tube 11. Then turn on the thermostat 21 to heat the liquid tube 11 at a constant temperature. Draw out the piston rod 12, and the liquid flows into the stomach by its own gravity. The temperature of the liquid tube 11 can be displayed through the temperature display screen 23. The above is the whole working principle of the present utility model.

[0034] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
