Description

Technical Field

[0001] The present invention relates to the field of medical care technology, and more specifically, to a liquid food feeding auxiliary device used in general practice nursing. Background Art

[0002] General care is a medical service model that aims to provide comprehensive basic care and health management. General care covers a wide range of health needs and disease management, providing patients with continuous, coordinated and individualized care at all stages. In nursing, patients with digestive tract diseases often need to be fed liquid food.

[0003] When the existing liquid food feeding and nursing devices are used for feeding, the liquid food in some devices is in an uninterrupted feeding state, and it is impossible to timely interrupt the flow of liquid food into the patient's mouth according to the patient's swallowing. The patient is in a passive feeding state, which may easily cause the liquid food to flow out of the patient's mouth or the patient may be choked due to excessive liquid food in the patient's mouth. Although some devices can avoid choking due to excessive food intake by relying on the patient to actively eat, patients who need liquid food auxiliary devices are often relatively weak, and active eating requires the patient to consume too much energy and spirit, which may easily affect the patient's recovery speed.

[0004] Therefore, in view of the above problems, the present invention proposes a liquid food feeding auxiliary device used in general nursing. Summary of the invention

[0005] The present invention provides a liquid food feeding auxiliary device for general nursing, so as to solve the technical problem in the prior art that when a patient is in passive feeding, feeding cannot be interrupted in time according to the patient's swallowing situation, so as to avoid excessive liquid food in the oral cavity flowing out of the oral cavity or choking.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0032] Embodiment:

[0033] As Figures 1 to 8As shown, a liquid food feeding auxiliary device used in general practice nursing comprises a base 1, a plurality of anti-slip strips are arranged at the bottom of the base 1, a feeding box 2 and a head support adjustment component are arranged on the left and right sides of the top of the base 1 respectively, a swallowing sensing component is detachably connected to the top of the head support adjustment component, a wireless transmitter is installed in the swallowing sensing component, a single-chip microcomputer and a wireless receiver are installed in the base 1, the single-chip microcomputer and the wireless receiver are electrically connected, the swallowing sensing component is electrically connected to the single-chip microcomputer built in the base 1 through the wireless transmitter and the wireless receiver, a liquid food bag 3 and an extrusion component for extruding the liquid food bag 3 are arranged in the feeding box 2, the extrusion component is electrically connected to the wireless transmitter electrically connected to the single-chip microcomputer built in the base 1 through the wireless receiver, a liquid food tube is arranged at the bottom of the liquid food bag 3 which passes through the feeding box 2, a feeding sleeve 4 is detachably connected to the liquid outlet end of the liquid food tube, a wireless solenoid valve is installed in the feeding sleeve 4, and the wireless solenoid valve is electrically connected to the single-chip microcomputer installed in the base 1.

[0034] like Figure 2 As shown, the swallowing sensing component includes an arc frame 16 detachably connected to the top of the support plate 6, an electric telescopic rod 17 is provided at the bottom of the arc frame 16, and a pressure-sensitive sensor 18 electrically connected to the built-in single-chip microcomputer of the base 1 is provided at the bottom of the electric telescopic rod 17.

[0035] In order to better adjust the position of the pressure-sensitive sensor 18, a mounting frame 19 is provided on the top of the arc frame 16, and a slider 20 is slidably connected inside the mounting frame 19. The electric telescopic rod 17 is arranged at the bottom of the slider 20. The mounting frame 19 is rotatably connected with a one-way threaded rod 21 that passes through the slider 20, and the right end of the one-way threaded rod 21 is provided with a knob extending outside the mounting frame 19.

[0036] The patient lies flat on the nursing bed, puts the head on the head support adjustment assembly, adjusts the angle, installs the arc frame 16 on the support plate 6, passes the liquid esophagus through the fixed cylinder of the arc frame 16, and then puts the liquid food bag 3 connected to the liquid esophagus into the extrusion assembly in the feeding box 2, and puts the feeding sleeve 4 into the patient's mouth. By turning the knob 1, the one-way threaded rod 121 can be rotated to drive the slider 20 to move left and right in the installation frame 19, and then the pressure-sensitive sensor 18 is gently pressed against the patient's Adam's apple through the electric telescopic rod 17. The single-chip microcomputer is used to control the extrusion assembly to squeeze the liquid food in the liquid food bag 3, so that the liquid food flows from the feeding sleeve 4 to the patient's mouth along the liquid esophagus. When the patient swallows, the Adam's apple moves up, and the pressure sensed by the pressure-sensitive sensor in the swallowing sensing assembly is significantly reduced. The action is thereby converted into an electrical signal and transmitted to a wireless receiver electrically connected to the single-chip computer through a wireless transmitter. The single-chip computer then transmits the electrical signal to the wireless solenoid valve and the extrusion assembly through an electrically connected wireless generator, thereby closing the wireless solenoid valve in the feeding sleeve 4 and the motor 29 in the extrusion assembly; after swallowing is completed, the Adam's apple moves downward, and the pressure sensed by the pressure sensitive sensor in the swallowing sensing assembly increases significantly, thereby converting the action into an electrical signal and transmitting it to a wireless receiver electrically connected to the single-chip computer through a wireless transmitter. The single-chip computer then transmits the electrical signal to the wireless solenoid valve and the extrusion assembly through an electrically connected wireless generator, thereby reopening the wireless solenoid valve in the feeding sleeve 4 and the motor 29 in the extrusion assembly; and this process is repeated until the feeding of the liquid food is completed.

[0037] like Figure 1 and Figure 3 As shown, the head support adjustment assembly includes a support plate 6 slidably connected to the base 1 and an arc-shaped worm wheel 5 fixedly sleeved on the right side of the base 1. The front and rear ends of the top of the base 1 are provided with an arc-shaped slideway for the support plate 6 to slide and connect. The bottom of the support plate 6 is rotatably clamped with a worm 7 meshing with the arc-shaped worm wheel 5. The left side of the worm 7 is provided with a motor 8 fixedly arranged at the bottom of the support plate. The top of the support plate 6 is provided with a neck pillow 9. The patient's head is placed on the support plate 6, and the neck is placed on the neck pillow 9. The motor 8 is started to drive the worm 7 to rotate. Under the action of the arc-shaped worm wheel 5, the rotating worm 7 is rotated along the arc-shaped worm wheel 5, thereby driving the support plate 6 to rotate along the arc-shaped slideway, so as to achieve the purpose of adjusting the angle of the support plate 6. In order to improve the stability of the support plate 6 after the angle adjustment, a fastening nut can be sleeved on the vertical rod passing through the arc-shaped slideway at the bottom of the support plate 6.

[0038] In order to improve the comfort of the patient, an airbag 10 is provided on the right side of the support plate 6. One end of the airbag 10 is connected to an air inlet pipe 11 and an air outlet pipe 12. A sealing cap 13 is provided at the port of the air outlet pipe 12. The air inlet pipe 11 is connected to an inflatable ball 14. Both ends of the inflatable ball 14 are provided with a one-way valve 15, so that during inflation, the gas can only flow into the airbag 10 through the inflatable ball 14 to inflate the airbag 10. A cavity for accommodating the inflatable ball 14 is provided on the right side of the base 1, and a limit gate is provided at the opening of the cavity. When in use, by squeezing the inflatable ball 14, the airbag 10 can be inflated under the action of two one-way valves 15 in the same direction. The inflated airbag 10 can fill the gap between the support plate 6 and the nursing bed, thereby achieving the purpose of improving the comfort of the patient. After use, the inflatable ball 14 can be stored in the cavity.

[0039] like Figure 6 and Figure 8 As shown, the extrusion assembly includes two mounting plates 22 symmetrically arranged in the feeding box 2, the top of the mounting plate 22 is rotatably clamped with a bevel gear 41, the top of the bevel gear 41 is threadedly connected with a one-way threaded rod 23 that penetrates the mounting plate 22, the bottom of the one-way threaded rod 23 is provided with a wedge block 24 that is slidably clamped with the mounting plate 22, the bottom of the wedge block 24 is provided with a matching wedge block 25, the side of the wedge block 25 close to the liquid food bag 3 is provided with an extrusion plate 26 through a spring, and the wedge block 25 and The mounting plate 22 is slidably engaged, the extrusion plate 26 is slidably engaged with the feeding box 2, the bevel gear 1 41 is meshed with a bevel gear 27 rotatably connected to the feeding box 2, and one side of the outer wall of the feeding box is rotatably engaged with two synchronous wheels 28 that achieve synchronous rotation through an elastic belt, and the two synchronous wheels 28 are coaxially fixedly connected to the two bevel gears 27 respectively, and one end of a synchronous wheel 28 is provided with a motor 29, which is installed on the side of the feeding box 2 through a fixing plate, and a limit block is provided on the top of the one-way threaded rod 23.

[0040] Put the liquid food bag 3 between the extrusion plates 26, start the motor 29, the motor 29 can drive the synchronous wheel 28 to rotate, thereby driving the two bevel gears 27 to rotate in the same direction, and then driving the two bevel gears 1 41 to rotate in the same direction. The rotating bevel gear 1 41 can make the one-way threaded rod 23 move up and down. When moving downward, it drives the wedge block 1 24 to squeeze the wedge block 25 downward, so that the spring between the wedge block 25 and the extrusion plate 26 is compressed. The compressed spring then pushes the extrusion plate 26 to move toward the liquid food bag 3, so as to squeeze the liquid food bag 3 so that the liquid food in the liquid food bag 3 flows to the liquid food tube; controlling the rotation speed of the motor 29 can control the extrusion strength of the extrusion plate 26, and then control the flow rate per unit time. Two symmetrically arranged wedge blocks 25 form a group, and three groups of wedge blocks 25 are arranged in sequence from top to bottom. The height of the wedge block 1 24 is higher than the height of the wedge block 25, so that when the extrusion plate 26 is squeezed, the liquid food in the liquid food bag 3 will not be squeezed to the top.

[0041] A bidirectional threaded rod 30 and a guide rod 31 that pass through the two mounting plates 22 are rotatably connected inside the feeding box 2. The two mounting plates 22 are respectively distributed at both ends of the bidirectional threaded rod 30. The bidirectional threaded rod 30 is provided with a knob 2 that passes through the left side of the feeding box 2 and extends to the outside of the feeding box 2. A sliding hole is provided on the front side of the feeding box 2. A slider 2 32 that is rotatably connected to the bevel gear 27 is slidably connected in the sliding hole. The motor 29 is slidably connected to the feeding box 2 through a fixed plate. The motor 29 is electrically connected to the wireless transmitter that is electrically connected to the single-chip microcomputer built into the base 1 through a wireless receiver.

[0042] The above technical solution can be used for liquid food bags 3 of different specifications. By rotating the bidirectional threaded rod 30, the distance between the two mounting plates 22 can be adjusted, thereby driving the wedge block 1 24 and the wedge block 2 25 to move, and then driving the extrusion plate 26 to move, so as to achieve the purpose of adjusting the distance between the extrusion plates 26. The elastic belt can be adaptively adjusted according to the distance between the two synchronous wheels 28, so as to ensure the transmission performance of the rotation of the two synchronous wheels 28.

[0043] like Figure 6 As shown, a crushing assembly is also provided in the feeding box 2, and the crushing assembly includes a liquid food tank 33 which is detachably clamped on the top of the feeding box 2, the output end of the liquid food tank 33 is detachably connected to the liquid inlet end of the liquid food bag 3, and a tank cover 34 is detachably connected to the top of the liquid food tank 33. The bottom of the liquid food tank 33 is a cone structure, and a baffle 35 for blocking the output end of the liquid food tank 33 is provided in the cone portion of the liquid food tank 33, and a pressing assembly is provided on the top of the tank cover 34, and a transmission rod 36 rotatably connected to the top of the tank cover 34 is provided in the pressing assembly, and the transmission rod 36 is provided with crushing blades 37 distributed in a circle, and the transmission rod 36 is magnetically fixed to the baffle 35 through the pressing assembly.

[0044] In addition to medical-grade liquid food, liquid food prepared by patients is also fed. Liquid food prepared by patients often has poor fluidity due to the large amount of added materials, so it needs to be further crushed. The baffle 35 is placed in the liquid food tank 33, and the liquid food prepared by the patient is poured into the clean and sterile liquid food tank 33. The tank cover 34 is covered, and the transmission rod 36 is connected to the baffle 35 by magnetic fixation. The rotating transmission rod 36 can drive the crushing blade 37 to rotate, thereby crushing the food in the liquid food tank 33. The tank cover 34 and the liquid food tube can be threadedly connected. When the tank cover 34 is rotated, the block can be driven to move up, so that the liquid food in the tank flows into the liquid food bag 3. A switch valve is provided at the connection between the liquid food bag 3 and the liquid food tank 33. When the food in the liquid food tank 33 completely flows into the liquid food bag 3, the switch valve needs to be closed to prevent the liquid food from flowing into the liquid food tank 33 when the squeezing plate 26 is squeezed.

[0045] like Figure 6 , Figure 7 and Figure 8As shown, the pressing assembly includes a mounting seat 38 fixedly mounted on the top of the tank cover 34, the mounting seat 38 is slidably connected with a pressing rod 1 39 and a pressing rod 2 40 that penetrate the tank cover 34, the pressing rod 1 39 and the pressing rod 2 40 are fixedly connected to the tank cover 34 through a spring, the pressing rod 1 39 is coaxially arranged with the transmission rod 36, the pressing rod 2 40 is not coaxially arranged with the transmission rod 36, the pressing rod 1 39 and the pressing rod 2 40 are vertically provided with a sliding rod 1 42, the inner wall of the mounting seat 38 is provided with a sliding groove for the sliding rod 1 42 to slide up and down, and the mounting seat 38 A slide plate 43 is connected internally for sliding movement. The slide plate 43 is provided with two limit grooves 44. The limit grooves 44 are composed of a wedge-shaped groove and a straight groove. The bottom of the limit groove 44 corresponding to the pressing rod 1 39 is provided with an extension groove 45 away from the wedge-shaped groove in the limit groove 44. A slide bar 2 46 is vertically provided on the left inner wall of the mounting seat 38. The slide plate 43 is provided with a limit hole for the slide bar 2 46 to slide back and forth in the horizontal direction. The slide bar 2 46 is fixedly connected to the slide plate 43 by a tension spring. A motor 3 47 fixedly connected to the transmission rod 36 is installed in the pressing rod 1 39.

[0046] The baffle plate 35 can be driven upward by the pressing assembly, so that the crushed liquid food in the liquid food pot 33 can flow into the liquid food bag 3; in the initial state, the pressing rod 1 39 and the pressing rod 2 40 are both located in the wedge-shaped groove of the limiting groove 44. At this time, the transmission rod 36 is not connected to the baffle plate 35. Until the liquid food in the liquid food pot 33 is completely crushed, a downward force is applied to the pressing rod 1 39, and the sliding rod 1 42 squeezes the corresponding wedge-shaped groove to drive the slide plate 43 to move backward. At this time, the sliding rod 2 46 slides forward relative to the sliding hole to stretch the tension spring, cancel the downward force, and the restoring force of the tension spring pulls the slide plate 43 recovers forward, thereby limiting the sliding rod 1 42 corresponding to the pressing rod 1 39 to the extension groove 45. At this time, the transmission rod 36 is fixedly connected to the baffle 35 through the magnetic block; then a downward force is applied to the pressing rod 2 40. Since the limiting groove 44 corresponding to the pressing rod 2 is not provided with the extension groove 45, when the downward force applied to the pressing rod 2 40 is cancelled, the pressing rod 1 39 and the pressing rod 2 40 both recover upward through the restoring force of the spring, thereby driving the baffle 35 to move upward, so that the liquid food tank 33 is connected to the liquid food bag 3, and the liquid food in the liquid food tank 33 can flow into the liquid food bag 3.

[0047] A mounting box 48 is fixedly mounted on the left side of the top of the base 1, wherein a worm 49 is mounted in the mounting box 48 and is rotatably connected to the inner wall of the mounting box 48. Worm wheels 50 rotatably engaged with the mounting box 48 are engaged on both sides of the worm 49. The worm wheel 50 is threadedly connected to a one-way threaded rod 3 51, which penetrates the mounting box 48 and is slidably connected to the mounting box 48. The feeding box 2 is fixedly mounted on the top of the two one-way threaded rods 3 51, and a crank extending to the outside of the mounting box 48 is mounted on the left end of the worm 49. Limiting plates are mounted on the one-way threaded rod 3 51 between the mounting box 48 and the feeding box 2 and on the bottom of the one-way threaded rod 3 51.

[0048] The above technical solution can adjust the height of the feeding box 2. By rotating the crank, the worm 2 49 can be driven to rotate, and then the worm wheel 50 can be driven to rotate. The rotating worm wheel 50 can drive the one-way threaded rod 3 51 to move up and down, thereby adjusting the height of the feeding box 2.

[0049] In addition, the liquid esophagus is also provided with a flow rate regulator for controlling the flow rate of the liquid food. The liquid esophagus passes through a fixed sleeve of the arc frame 16, and the inner wall of the fixed sleeve is provided with a constant temperature electric heating ring that wraps the liquid esophagus.

[0050] The specific usage of this embodiment is as follows:

[0051] The patient lies flat on the nursing bed, puts the head on the head support adjustment assembly, adjusts the angle, installs the swallowing sensing assembly frame on the top of the head support adjustment assembly, and then puts the liquid food bag 3 connected to the liquid food tube into the extrusion assembly in the feeding box 2, and puts the feeding sleeve 4 into the patient's mouth. If the liquid food prepared by the patient himself needs to be crushed, the crushing assembly can be used to crush the liquid food in the liquid food tank 33, and the height of the feeding box 2 is adjusted. The pressure-sensitive sensor 18 in the swallowing sensing assembly is gently pressed against the patient's Adam's apple, and the extrusion assembly is controlled by a single-chip microcomputer to squeeze the liquid food in the liquid food bag 3, so that the liquid food flows vertically from the feeding sleeve 4 to the patient's mouth through the liquid food tube. When the patient swallows, the Adam's apple moves up, and the pressure sensed by the pressure-sensitive sensor in the swallowing sensing assembly is significantly reduced, thereby converting the action into an electrical signal and transmitting it to the wireless receiver electrically connected to the single-chip microcomputer through a wireless transmitter. The single-chip microcomputer then transmits the electrical signal to the wireless solenoid valve and the extrusion assembly through an electrically connected wireless generator. In the device, the wireless solenoid valve in the feeding sleeve 4 and the motor 29 in the extrusion assembly are closed; after swallowing is completed, the Adam's apple moves down, and the pressure sensed by the pressure sensitive sensor in the swallowing sensing assembly increases significantly, thereby converting the action into an electrical signal and transmitting it to the wireless receiver electrically connected to the single-chip computer through a wireless transmitter. The single-chip computer then transmits the electrical signal to the wireless solenoid valve and the extrusion assembly through an electrically connected wireless generator, and reopens the wireless solenoid valve in the feeding sleeve 4 and the motor 29 in the extrusion assembly; this is repeated until the feeding of the liquid food is completed.
