Description

Technical Field

[0001] The utility model relates to the technical field of nasogastric feeding supplies, in particular to a nasogastric feeding device. Background Art

[0002] For patients who are bedridden and comatose and cannot swallow autonomously, nasogastric feeding is usually used to provide them with water and food to maintain metabolism and nutrition. However, the common nasogastric feeding device is a large syringe. First, the food is sucked into the syringe through the nipple of the syringe, and then the syringe is connected to the nasogastric tube. After that, the syringe is pushed to inject the food. There are the following problems in the specific operation:

[0003] 1. The inner diameter of the syringe nipple is small, so it takes a lot of time to draw food into the syringe. If a large piece of food blocks the nipple, it takes a lot of force to pull the piston of the syringe. If too much force is used, the piston will be directly pulled out of the syringe, causing the food to flow out through the nipple again. The operation is time-consuming and laborious.

[0004] 2. When feeding with a syringe, although the food has been ground as much as possible, it is inevitable that the ground food will still accumulate into lumps, which are larger than the inner diameter of the nasogastric tube. In addition, the syringe itself lacks the structure to divide and crush the food, which may cause blockage of the nasogastric tube. At this time, it is necessary to increase the force of the push injection, which can easily cause the patient to choke, increase the difficulty of feeding, and increase the patient's discomfort. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide a nasogastric feeding device, which effectively solves the problem that it is inconvenient to quickly fill food into the existing syringe and the existing device is inconvenient to crush the food.

[0006] The technical solution is that the utility model comprises a main body cylinder in the upper and lower axial direction, a liquid outlet hole which passes through the main body cylinder in the upper and lower ends, a nipple which is connected with the liquid outlet hole and in the upper and lower axial direction is provided at the lower end of the main body cylinder, a baffle which can block the liquid outlet hole is slidably connected in the lower side wall of the main body cylinder, a leakage hole which passes through the main body cylinder in the upper and lower ends and can be connected with the liquid outlet hole is provided on the baffle, a piston which can be moved up and down is coaxially detachably connected in the main body cylinder, a clearance groove is coaxially provided at the lower end of the piston, a fixing ring which can be moved up and down is coaxially placed in the clearance groove, and a grid-shaped blade is coaxially fixed at the lower end of the fixing ring.

[0007] The beneficial effects of the utility model are as follows: there is no need to extract liquid food through the nipple, but the liquid food can be directly poured into the main body tube, which makes the operation faster and improves the feeding efficiency. After the liquid food is poured in, the pressure plate is pressed to make the grid-shaped blade move up and down in the main body tube to cut and crush the liquid food, thereby preventing the liquid food from agglomerating, reducing the blockage of the nasogastric tube, increasing the comfort of the patient, and facilitating the medical staff to perform nasogastric feeding on the patient.

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 7 The invention provides a main body tube 1 which is axially arranged in the up-and-down direction, a liquid outlet hole 2 which passes through the main body tube 1 in the lower end, a nipple 3 which is connected with the liquid outlet hole 2 and is axially arranged in the up-and-down direction, a baffle 4 which can block the liquid outlet hole 2 is slidably connected in the lower side wall of the main body tube 1, a leakage hole 5 which passes through the main body tube 4 and can be connected with the liquid outlet hole 2 is provided on the baffle 4, a piston 6 which can be moved up and down is coaxially detachably connected in the main body tube 1, a clearance groove is coaxially provided in the lower end of the piston 6, a fixing ring 7 which can be moved up and down is coaxially placed in the clearance groove, and a grid-shaped blade 8 is coaxially fixed to the lower end of the fixing ring 7.

[0017] In order to enable the piston 6 to move up and down, a connecting rod 9 is coaxially provided on the upper end of the piston 6, a grip 10 in left and right directions is provided on the outer end of the main tube 1, and a pressure handle 11 in left and right directions is provided on the right end of the connecting rod 9.

[0018] In order to enable the fixing ring 7 to move up and down, a cross-shaped fixing rod 12 is provided at the upper end of the fixing ring 7, and a pressure rod 13 coaxial with the connecting rod 9 is provided on the fixing rod 12. The upper end of the pressure rod 13 passes through the piston 6 and the connecting rod 9 and is provided with a pressure plate 14. The lower end of the pressure plate 14 is connected to the connecting rod 9 via a compression spring.

[0019] In order to better cut the food, the fixing rod 12 is located above the blade 8 and does not contact the blade 8. The size of the grid on the blade 8 is smaller than the inner diameter of the nasogastric tube.

[0020] In order to facilitate the control of the movement of the baffle 4 , a slider 15 is slidably connected to the baffle 4 . A limit rod 16 penetrating through the main tube 1 is provided at the lower end of the slider 15 . The limit rod 16 is slidably connected to the baffle 4 .

[0021] In order to limit the baffle 4 , a concave groove 17 in the front-to-back direction and with the notch facing left is opened at the lower end of the main body tube 1 , and the lower end of the limiting rod 16 extends out of the concave groove 17 and can move in the concave groove 17 .

[0022] When the utility model is in use, the initial state is that the limit rod 16 is located at the limit position of the front side of the concave groove 17 and inserted into the left and right parts of the front side of the concave groove 17, the baffle plate 4 blocks the liquid outlet hole 2, the leakage hole 5 is located in front of the liquid outlet hole 2, and the position of the baffle plate 4 is limited;

[0023] Pull out the piston 6 and pour the liquid food directly into the main body tube 1. Since the baffle 4 blocks the liquid outlet 2 at this time, the liquid food poured into the main body tube 1 will not flow out through the liquid outlet 2, and there is no need to extract the liquid food through the nipple 3, which is more convenient and quick, and improves the feeding efficiency;

[0024] When the amount of liquid food in the main tube 1 reaches the required amount, the piston 6 is inserted into the main tube 1 and the pressure plate 14 is pressed downward. The pressure plate 14 drives the pressure rod 13 to move downward. Since the main tube 1 and the piston 6 form a closed environment at this time, the piston 6 will not move downward with the pressure rod 13, and the compression spring is contracted under the force. The pressure rod 13 drives the fixing rod 12 and the fixing ring 7 to move downward, and the blade 8 moves downward synchronously. The soft and rotten large pieces of food and the agglomerated food in the liquid food are gradually broken under the cutting of the blade 8. The broken food passes through the grid on the blade 8 and moves from the bottom of the blade 8 to the top of the blade 8. When the lower end of the blade 8 contacts the lower side wall of the main tube 1, one cutting is completed, and the pressure plate 14 is released. The pressure plate 14 drives the blade 8 to move upward under the action of the compression spring, and the liquid food passes through the grid on the blade 8 and moves from the top of the blade 8 to the bottom of the blade 8. This reciprocating process is repeated many times, so that the liquid food in the main tube 1 is fully cut and broken to prevent the existence of larger particles of food.

[0025] After the food is crushed, the limit rod 16 is pushed to the right, and the limit rod 16 drives the slider 15 to move to the right, so that the limit rod 16 moves from the left and right part of the concave groove 17 to the front and rear part, and the limit of the limit rod 16 is released. The limit rod 16 is pushed backward, and the limit rod 16 drives the slider 15 and the baffle 4 to move backward, and the leakage hole 5 gradually approaches the liquid outlet hole 2. When the limit rod 16 moves to the limit position on the rear side of the concave groove 17, the leakage hole 5 is coaxial with the liquid outlet hole 2. Since the piston 6 is inserted into the main body tube 1 at this time, under the action of atmospheric pressure, even if the leakage hole 5 is connected with the liquid outlet hole 2, the liquid food will not flow out of the main body tube 1. The limit rod 16 is pushed to the left, and the limit rod 16 drives the slider 15 to move to the left, and the limit rod 16 is inserted into the left and right part of the rear side of the concave groove 17. The position of the baffle 4 is limited, and the leakage hole 5 remains connected with the liquid outlet hole 2.

[0026] Connect the nipple 3 to the nasogastric tube, hold the handle 10, push the pressure handle 11, and make the pressure handle 11 close to the handle 10. The piston 6 pushes the liquid food into the nasogastric tube through the liquid outlet 2, the leakage hole 5 and the nipple 3, so that the patient can eat. After the patient finishes eating, the main tube 1 is cleaned normally. When used next time, the limit rod 16 is moved to the left and right parts of the front side of the concave groove 17 again to repeat the above operation.

[0027] The main body tube 1 in the present invention can be made of a transparent material, which makes it easy to observe the internal conditions of the main body tube 1.

[0028] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicality. Through the arrangement of the blade, the fixing ring, the fixing rod, the pressure rod, the piston, the connecting rod, the pressure plate and the pressure spring, the grid-shaped blade is moved up and down by pressing the pressure plate, so that the larger pieces of food in the liquid food are cut and crushed. Then, the piston is driven to move downward by pressing the pressure handle to squeeze the liquid food, so that the liquid food enters the patient's body through the nasogastric tube, thereby crushing the liquid food and preventing the liquid food from agglomerating and blocking the nasogastric tube. The utility model is safer and more reliable. Through the arrangement of the baffle plate, the liquid outlet hole, the leakage hole, the limiting rod, the sliding block and the concave groove, the movement of the limiting rod is controlled to control the movement of the baffle plate, and then whether the baffle plate blocks the liquid outlet hole is controlled. There is no need to suck the liquid food into the main body tube through the nipple, but the liquid outlet hole is blocked by the baffle plate, so that the lower end of the main body tube is in a closed state, and then the liquid food is directly poured into the main body tube through the upper end of the main body tube. The operation is simpler, more time-saving and labor-saving, and the feeding efficiency is improved.
