Description

Technical Field

[0001] The utility model relates to the technical field of liquid food feeding auxiliary equipment, in particular to a liquid food supply device for the digestive tract. Background Art

[0002] Liquid food is a kind of liquid food, including but not limited to clear chicken soup, clear meat soup, vegetable water, suitable for critically ill patients who are extremely weak and unable to chew food, such as patients with high fever, oral and cheek diseases, and before and after surgical operations. The gastroenterology department of the hospital generally uses a syringe to suck out the liquid food, and then feeds the liquid food to the patient through a nasogastric tube or gastric feeding. The operation is frequent and not only inefficient.

[0003] In the patent document with the announcement number CN202666014U, a liquid food supply device for gastroenterology is disclosed, in which the liquid food is injected into a bottle body, and then the gas is transported into the bottle body by kneading the air bag. By increasing the air pressure in the bottle body, the liquid food is forced to flow from the bottle body to the nasogastric feeding tube or the gastric feeding tube, thereby completing the feeding. By controlling the rate of kneading the air bag, the speed of the liquid food outflow is controlled, and then the patient's eating speed is controlled.

[0004] This patent does not require sucking liquid food through tubes, which improves efficiency. However, after repeated pinching of the air bag, the hands will become sore and tired, and the air pressure in the bottle cannot be stably regulated by pinching the air bag. If the air bag is pinched too quickly, the liquid food will overflow and cause the patient to choke.

[0005] To this end, the utility model provides a digestive tract liquid food supply device, which ensures the liquid food supply efficiency and the stability of the liquid food supply rate. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the attached embodiment of the utility model Figure 1-10 , the technical solutions in the embodiments of the utility model are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0034] Embodiment 1, in order to solve the problems existing in the prior art, this embodiment provides a digestive tract liquid food supply device, including a liquid food bottle 1, the liquid food bottle 1 is made of food-grade transparent material, the outer wall of the liquid food bottle 1 is provided with a scale for recording the amount of food intake, the liquid food bottle 1 includes a handheld end 101 and a separation end 102, the handheld end 101 is provided with an internal thread on the side facing the separation end 102, and the separation end 102 is provided with an external thread on the side facing the handheld end 101, the handheld end 101 and the separation end 102 are fixedly connected by kneading the internal thread and the external thread, so that the handheld end 101 and the separation end 102 can be detached and separated, which is convenient for cleaning the inside of the liquid food bottle 1, and the outer wall of the handheld end 101 is provided with a handle for easy holding;

[0035] The separation end 102 is designed to be closed on the side away from the handheld end 101 and is connected to a feed pipe 2, which is connected to a stop chamber 3. A flow limiting column 4 is embedded in the stop chamber 3. A screw 5 is provided on the side wall of the flow limiting column 4. The screw 5 is threadedly connected to the side wall of the stop chamber 3. The end of the screw 5 extends out from the stop chamber 3. A hose 6 is connected to the side of the stop chamber 3 away from the feed pipe 2. The hose 6 is aligned with the connecting part of the feed pipe 2 and the stop chamber 3, and the end of the hose 6 is connected to a feeder 8.

[0036] The bottom wall of the handheld end 101 is recessed 9 inwardly, and an air pressure valve is provided at the recess 9. The air pressure valve includes a tapered hole 10 provided at the recess 9 of the handheld end 101, a tapered plug 11 is embedded in the tapered hole 10, a support rod 12 vertically slidably connected to the tapered hole 10 is fixed to the upper end of the tapered plug 11, the support rod 12 extends out of the handheld end 101, a compression spring is provided between the support rod 12 and the handheld end 101, a touch rod is provided on the side wall of the support rod 12, a driving ring 13 coaxial with the support rod 12 is provided at the recess 9 of the handheld end 101, and a knob is provided on the outer wall of the driving ring 13, so that When the driving ring 13 is twisted, a wave groove 14 connected end to end is provided on the inner wall of the driving ring 13. The heights of two adjacent peaks of the wave groove 14 are different, while the two separated peaks are the same, such as the first peak and the third peak are the same, the second peak and the fourth peak are the same, and all the valleys of the wave groove 14 are the same. The touch rod is slidably installed in the wave groove 14; the driving ring 13 is located in the recess 9 and the upper end surface is lower than the upper end surface of the handheld end 101, so that the air pressure valve is retracted to prevent the liquid food bottle 1 from being unstable when placed due to the bulging size when it is square.

[0037] The specific use process of this embodiment is as follows:

[0038] Before eating, hold the handheld end 101 and twist the separation end 102 to open the liquid food bottle 1. After pouring the liquid food, close the handheld end 101 and the separation end 102.

[0039] When eating, the liquid food bottle 1 is turned upside down. Under the action of air pressure, the liquid food is retained in the liquid food bottle 1 and will not flow out, thereby avoiding the problem of leakage when the liquid food bottle 1 is accidentally touched or tilted, and improving the tightness of the liquid food packaging; then the feeder 8 is placed in the patient's mouth, the drive ring 13 is screwed, the drive ring 13 is deflected, and the feeler rod moves vertically along the wave groove 14, thereby driving the cone plug 11 to move downward through the support rod 12. When the feeler rod moves to the bottom of the wave groove 14, under the action of the compression spring, the feeler rod quickly moves to the adjacent peaks of the wave groove 14. Since there is a height difference between the two adjacent peaks of the wave groove 14, the feeler rod moves from the peak of the wave groove 14 to the bottom of the wave groove 14. Transfer to the low peak, the cone plug 11 moves downward relatively, and a gap is formed between the cone hole 10 and the cone plug 11, that is, the interior of the liquid food bottle 1 is connected to the air pressure. Under the action of its own weight, the liquid food begins to flow into the feeding tube 2. No extra manual operation is required, and the operation is simpler and more convenient. The screw 5 is rotated, and the screw 5 moves out of the stop chamber 3, so that the flow limiting column 4 is gradually separated from the feeding tube 2 and the pipe opening of the hose 6. At this time, the feeding tube 2, the stop chamber 3, and the hose 6 are connected, and the liquid food gradually flows into the feeder 8, and then enters the patient's mouth, and starts eating. The screw 5 is rotated to control the relative position of the flow limiting column 4 and the pipe openings of the hose 6 and the feeding tube 2, so as to control the eating speed and avoid choking.

[0040] After eating, the screw 5 is first screwed to make the flow-limiting column 4 re-block the hose 6 and the outlet of the feed pipe 2 to start intercepting the remaining liquid food, and then the drive ring 13 is screwed, and the feeler rod moves along the wave groove 14 again, from the low peak of the wave groove 14 to the high peak, and the cone plug 11 blocks the cone hole 10 again, thereby closing the liquid food bottle 1. At this time, the liquid food bottle 1 can be straightened and the liquid food will not overflow.

[0041] In embodiment 2, a buckle ring 7 is fixed to the side wall at the end of the hose 6, and the feeder 8 is buckled on the buckle ring 7. The feeder 8 has two types: a nipple type and a long tube type, corresponding to gastric feeding and nasogastric feeding respectively. The feeder 8 is replaceable, which is easy to clean and also convenient to replace different feeders 8 according to the needs of different patients, thereby improving the flexibility and practicality of use.

[0042] In embodiment 3, the feeder 8 is made of food-grade rubber, which is flexible and more comfortable to use.

[0043] In embodiment 4, a sealing plate is provided on the top wall of the conical hole 10, and a through hole is provided at the sealing plate, through which the button passes. The diameter of the through hole is larger than the diameter of the button, so that the channel for connecting the liquid food bottle 1 with the outside world is at the through hole rather than at the upper end of the conical hole 10, so that when the conical plug 11 blocks the conical hole 10, a stepped contact surface is formed: the upper end surface of the conical plug 11 and the bottom surface of the sealing plate, the side wall of the conical plug 11 and the inner wall of the conical hole 10, thereby improving the airtightness.

[0044] The side wall of the support rod 12 is symmetrically provided with two sliding grooves, and the side wall of the through hole is provided with a sliding block slidably matched with the sliding grooves, so that the support rod 12 can slide vertically relative to the tapered hole 10.

[0045] In Example 5, the cone plug 11 is a food-grade rubber plug, which utilizes deformation extrusion to improve the sealing performance.

[0046] In Embodiment 6, a collar 15 is detachably fixed to the upper end of the support column, and the feeler rod is arranged on the collar 15, so that the cone plug 11 is detachable for easy cleaning and replacement.

[0047] Embodiment 7: In this embodiment, two other specific structures of air pressure valves are provided:

[0048] The second method: a conical hole 10 is provided at the depression 9 of the handheld end 101, a conical plug 11 is provided at the conical hole 10, a screw rod 16 is provided at the upper end of the conical plug 11, a knob is provided at the upper end of the screw rod 16, the screw rod 16 is threadedly connected to the tip of the conical hole 10, and the screw rod 16 is screwed to control the lifting and lowering of the conical plug 11, thereby controlling whether the liquid food bottle 1 is connected to the outside world;

[0049] The third type: a conical hole 10 is provided at the depression 9 of the handheld end 101, and an air pipe 17 is connected to the conical hole 10. A sealing cap is threadedly connected to the mouth of the air pipe 17. By unscrewing the sealing cap, the liquid food bottle 1 can be connected to the outside world, and liquid food can be injected into the liquid food bottle 1 from the air pipe 17 during eating. When the liquid food in the liquid food bottle 1 is finished, there is no need to separate the liquid food bottle 1, thereby improving efficiency.
