Description

Technical Field

[0001] This utility model relates to the field of nursing technology, specifically to a positional support nursing device for oral feeding of premature infants. Background Technology

[0002] Premature infants (gestational age <37 weeks) often have problems such as weak sucking and uncoordinated swallowing due to immature muscle development, which leads to difficulties in oral feeding and requires artificial feeding. Oral feeding is a highly complex activity involving the integration and coordination of multiple systems such as the nervous and motor systems. Premature infants in the NICU face more difficulties in oral feeding due to immature nervous system development, lack of oral motor function, and disordered sucking-swallowing-breathing patterns and critical illness. Safe and effective complete oral feeding is the ultimate goal of nutritional support for premature infants and an important indicator for measuring whether they have met the discharge criteria.

[0003] When feeding premature infants orally, their heads should be kept slightly elevated to avoid choking and aspiration. Traditional feeding often relies on caregivers manually adjusting the infant's position, requiring continuous support for the infant's back and head. Prolonged support during feeding increases the workload of medical staff. Therefore, we need to propose a positional support device for oral feeding of premature infants. Utility Model Content

[0004] The purpose of this invention is to provide a positional support nursing device for oral feeding of premature infants, which facilitates the adjustment of the premature infant's lying position and can slightly lift the premature infant's body and head, thereby facilitating feeding and solving the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a positional support and care device for oral feeding of premature infants, comprising:

[0025] Support mechanism 20, and nursing bed 10 for oral feeding of premature infants installed on support mechanism 20;

[0026] The posture adjustment mechanism 30 installed under the nursing bed 10 enables the adjustment of the angle of the upper body of the premature infant when lying down.

[0027] The nursing bed 10 includes a lower bed 101 and an upper bed 102 connected by hinges. The support mechanism 20 and the posture adjustment mechanism 30 are both installed under the lower bed 101.

[0028] The posture adjustment mechanism 30 includes an electric push rod 304, a support rod 307, and a second hinge seat 308. The second hinge seat 308 is fixedly connected to the end of the upper body bed 102 away from the lower body bed 101. The support rod 307 is rotatably mounted on the second hinge seat 308. The telescopic end of the electric push rod 304 is fixedly connected to the first hinge seat 306. One end of the support rod 307 is rotatably connected to the first hinge seat 306. The tilt angle of the upper body bed 102 can be adjusted by adjusting the tilt angle of the support rod 307 through the electric push rod 304. The position of the first hinge seat 306 can be adjusted by adjusting the position of the electric push rod 304, thereby facilitating the change of the tilt angle of the support rod 307, so as to adjust the tilt angle of the upper body bed 102 and facilitate oral feeding of premature infants.

[0029] The posture adjustment mechanism 30 also includes a base plate 301. Two sets of connecting blocks 302 are fixedly connected to the upper surface of the base plate 301. Both sets of connecting blocks 302 are fixedly connected to the lower surface of the lower bed 101. An electric push rod 304 is installed on the upper surface of the base plate 301. A guide rail 305 is provided on the upper surface of the base plate 301 for the first hinge seat 306 to slide on. The guide rail 305 improves the stability of the first hinge seat 306 when it moves. The connecting blocks 302 enable the base plate 301 to be angled with the nursing bed 10 as a whole, thereby improving the stability of the upper bed 102.

[0030] The upper surface of the upper bed 102 is provided with a high slope along the edge, and the upper surface of the lower bed 101 is provided with a low slope along the edge. Both the upper surfaces of the upper bed 102 and the lower bed 101 are provided with Velcro hook-and-loop fasteners 104 for attaching mattresses. A guard strip 103 is provided at the connection end between the upper bed 102 and the lower bed 101. The guard strip 103 covers the gap between the upper bed 102 and the lower bed 101, thereby improving the safety of the upper bed 102 when adjusting its tilt angle and preventing injury to the premature infant. At the same time, the high slope and low slope can prevent the premature infant from falling, improving the safety of care. The Velcro hook-and-loop fasteners 104 make it easy to place a quilt with Velcro hook-and-loop fleece fabric on the nursing bed 10, increasing the comfort of the premature infant lying down.

[0031] Two sets of buffer pillars 303 are fixedly connected to the upper surface of the substrate 301, and buffer pads are provided at the upper ends of the two sets of buffer pillars 303. The buffer pillars 303 can improve the stability of the upper bed 102 in a horizontal state, thereby improving the overall service life of the nursing bed 10.

[0032] The support mechanism 20 includes a base plate 201, a support seat 202 fixedly connected to the upper surface of the base plate 201, a connecting seat 203 rotatably mounted on the support seat 202, and the connecting seat 203 fixedly connected to the lower surface of the lower bed 101. The base plate 201 is provided with an adjustment component for adjusting the tilt angle of the lower bed 101. By fixing the base plate 201 to the nursing table, it is convenient to place the premature infant in the nursing bed 10, which is convenient to use. At the same time, the rotation axis of the support seat 202 and the axis of the adjustment gear block 208 are set on the same straight line, which facilitates the horizontal angle adjustment of the lower bed 101.

[0033] The adjustment assembly includes two sets of fixed plates 204 and an adjustment gear block 208. A screw 206 is rotatably connected between the two sets of fixed plates 204. A rack 207 is threaded onto the screw 206. The adjustment gear block 208 is fixedly connected to the lower surface of the lower body bed 101 and meshes with the rack 207. One end of the screw 206 passes through the fixed plate 204 and is driven by a motor 209. A controller 40 is provided on the lower surface of the lower body bed 101 and is electrically connected to the motor 209 and the electric push rod 304. The motor 209 drives the screw 206 to adjust the position of the rack 207, thereby causing the rack 207 to mesh with the adjustment gear block 208, so as to drive the adjustment gear block 208 to rotate. This facilitates the horizontal angle adjustment of the lower body bed 101 and allows for gentle rocking of the nursing bed 10, improving the sleep effect for premature infants.

[0034] Two sets of guide beams 205 are fixedly connected between the two sets of fixed plates 204 to guide the rack 207, and the rack 207 is slidably disposed between the two sets of guide beams 205. The guide beams 205 improve the stability of the movement of the rack 207.

[0035] When it is necessary to adjust the lying angle of the premature infant's upper body, the controller 40 activates the electric push rod 304, whose telescopic end drives the support rod 307 to move through the first hinge 306. One end of the support rod 307 is hinged to the second hinge 308 on the lower surface of the upper body bed 102, and the other end changes its tilt angle as the electric push rod 304 extends and retracts, thereby pushing the upper body bed 102 to rotate around the hinge connection. When the electric push rod 304 extends, the support rod 307 pushes the upper body bed 102 upward, increasing its tilt angle, which can slightly lift the premature infant's body and head, thus facilitating feeding. When the electric push rod 304 retracts, the upper body bed 102 falls back under the action of gravity, and the guide rail 305 provides lateral sliding guidance for the first hinge 306 to ensure the smooth movement of the support rod 307 and avoid force deviation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
