Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a feeding and medication dispensing device with flow control function. Background Technology

[0002] With the increasing aging of society, the nursing needs of elderly bedridden patients and people with swallowing difficulties are growing. Liquid diets and ground medicines have become the main means of nutrition supply for these patients due to their easy swallowing and digestion characteristics. When administering liquid diets or ground medicines to patients, feeding and medication dispensers are required.

[0003] Existing feeding and medication devices include electric feeding and medication devices and manual feeding and medication devices. Electric feeding and medication devices are powered by electricity and can automatically push liquid food into the patient's body, reducing the burden on caregivers. Manual feeding and medication devices are made by manually squeezing the feeding container to squeeze out liquid food for the patient to eat.

[0004] However, traditional feeding and medication dispensers deliver liquid food by squeezing, which is laborious to operate and has inaccurate flow rate control, easily leading to choking or aspiration in patients. Secondly, although electric feeding and medication dispensers can achieve flow control, they are difficult to implement personalized feeding, and are difficult for the elderly to operate for different feeding speeds. They are also not easy to disassemble and clean, which makes it easy for bacteria to grow inside the container, posing a hygiene risk. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where feeding and medicine dispensing devices are difficult to control the flow rate of liquid food and are difficult to clean, posing hygiene risks. Therefore, this invention proposes a feeding and medicine dispensing device with flow control function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A feeding and medicine dispensing device with flow control function includes a can and a sealing cover threaded onto the can, and a straw installed on the sealing cover by a press pump. A limiting ring is fixedly connected to the sealing cover and is sleeved on the outside of the straw. A pressure plate is installed on the limiting ring by an adjusting component. When the adjusting component is rotated, the pressure plate is used to squeeze the straw.

[0008] In order to drive the pressure plate to rotate and squeeze the suction tube, preferably, the adjusting component includes a rotating rod threadedly connected to the limiting ring, and the pressure plate is eccentrically sleeved on the rotating rod.

[0009] For extracting liquid food from inside the tank, preferably, the pump includes: a pump body threadedly connected to a sealing cap, a piston plate slidably connected within the pump body, wherein a piston rod is fixedly connected to the piston plate, and the end of the piston rod away from the piston plate passes through the pump body and is fixedly connected to a pressing head; an inlet valve fixedly installed within the pump body, an inlet pipe inserted into the inlet end of the pump body, the inlet pipe communicating with the inner cavity of the pump body, wherein a spring is provided within the pump body, the two ends of the spring respectively abutting against the piston plate and the pump body, and an outlet valve threadedly connected to the outlet end of the pump body, which is connected to a suction tube, and the outlet valve communicating with the inner cavities of the pump body and the suction tube.

[0010] To facilitate patient biting and sucking, the straw is preferably tilted and at a 45-degree angle to the pressure head.

[0011] To facilitate the installation and removal of the sealing cap, preferably, the sealing cap is provided with anti-slip stripes, and the anti-slip stripes and the sealing cap are integrally formed.

[0012] To avoid harming patients, the straw is preferably made of medical-grade silicone.

[0013] To facilitate the application of external force to pressurize the container and discharge the liquid food, preferably, the container includes an inner layer, a middle layer, and an outer layer, with the middle layer fixedly connected to the inner and outer layers.

[0014] To further enhance the flexibility of the can, the inner layer is made of food-grade flexible PP material with a thickness of 0.5mm.

[0015] To further improve the transparency of the tank, the intermediate layer is made of EVOH oxygen barrier film material.

[0016] To provide support for the tank, the outer layer is made of rigid PP material with a thickness of 1mm.

[0017] Compared with the prior art, this utility model provides a feeding and medicine dispensing device with flow control function, which has the following beneficial effects:

[0018] 1. This feeding and medicine delivery device with flow control function, through the setting of the press pump, continuously presses the press head to allow the liquid food inside the tank to enter the suction tube through the pump body, which can realize the delivery of liquid food. Moreover, both the inlet valve and the outlet valve are one-way valves, which can prevent the liquid food from flowing back and contaminating the internal environment of the tank.

[0019] 2. This feeding and medication applicator with flow control function uses an inclined straw, which makes it easier for patients to bite and hold the applicator, thereby improving its portability.

[0020] 3. This feeding and medication dispenser with flow control function has a certain degree of toughness through a can body composed of an inner layer, a middle layer and an outer layer.

[0031] Example:

[0032] Reference Figures 1-6 A feeding and medication dispensing device with flow control function includes a canister 1 and a sealing cap 2 threadedly connected to the canister 1. The sealing cap 2 has anti-slip stripes, and the anti-slip stripes and the sealing cap 2 are integrally formed. The anti-slip stripe design makes it easy to open the sealing cap 2 for cleaning. It also includes a straw 4 installed on the sealing cap 2 by a press pump. The straw 4 is made of medical-grade silicone, which has a long service life and is harmless to the human body. A limiting ring 5 is fixedly connected to the sealing cap 2 and is sleeved on the outside of the straw 4. The limiting ring 5 is equipped with a pressure plate 6 through an adjusting component. When the adjusting component is rotated, the pressure plate 6 is used to squeeze the straw 4, thereby achieving flow control of liquid food.

[0033] Specifically, the pump allows liquid food or medicine to be drawn from the canister 1 into the straw 4, and the flow is controlled by the regulating device to prevent the patient from choking. At the same time, the inlet valve 34 and outlet valve 37 on the pump prevent the liquid food or medicine from flowing back. Furthermore, the pump is connected to the sealing cover 2 and the straw 4 by threads and plugs, which allows for quick disassembly, thereby improving the cleanliness and efficiency of the feeding or medication dispenser.

[0034] The adjusting component includes a rotating rod 7 threadedly connected to a limiting ring 5, and a pressure plate 6 eccentrically sleeved on the rotating rod 7.

[0035] Specifically, by adjusting the mechanism, the rotating rod 7 rotates on the limiting ring 5 and moves downward, which can adjust the eccentrically designed pressure plate 6. By using the pressure plate 6 to squeeze the straw 4, flow control can be achieved, thereby preventing the patient from choking.

[0036] The press pump includes: a pump body 3, threadedly connected to a sealing cover 2; a piston plate 31 slidably connected to the inner cavity of the pump body 3; a piston rod 32 fixedly connected to the piston plate 31; one end of the piston rod 32 away from the piston plate 31 passing through the pump body 3 and fixedly connected to a press head 33; and an inlet valve 34 fixedly installed inside the pump body 3. The inlet valve 34 is a one-way valve, spherical in shape, allowing liquid to flow from the tank 1 into the pump body 3 while preventing liquid from flowing back into the tank 1. The inlet valve of the pump body 3... An inlet pipe 35 is inserted into the pump body 3, and the inlet pipe 35 is connected to the inner cavity of the pump body 3. The pump body 3 is equipped with a spring 36, and the two ends of the spring 36 abut against the piston plate 31 and the pump body 3 respectively. The outlet end of the pump body 3 is threadedly connected to an outlet valve 37 that is inserted into the suction tube 4. The outlet valve 37 is the same as the inlet valve 34, and both are one-way valves, which only allow liquid to flow from the pump body 3 to the suction tube 4, while preventing air from entering the pump body 3 from the suction tube 4. The outlet valve 37 is connected to the inner cavity of the pump body 3 and the suction tube 4.

[0037] Specifically, by continuously pressing the pump head 33, the liquid inside the tank 1 enters the suction pipe 4 through the pump body 3, thus realizing the delivery of liquid. Furthermore, both the inlet valve 34 and the outlet valve 37 are one-way valves, which can prevent the liquid or medicine from flowing back and contaminating the internal environment of the tank 1.

[0038] The straw 4 is tilted and forms a 45-degree angle with the pressing head 33.

[0039] Specifically, the inclined straw 4 makes it easier for patients to bite and hold the food, thereby improving the portability of the feeding or medication delivery device.

[0040] The tank 1 includes an inner layer 11, a middle layer 12 and an outer layer 13. The middle layer 12 is fixedly connected to the inner layer 11 and the outer layer 13. The inner layer 11 is made of food-grade flexible PP material with a thickness of 0.5mm. The middle layer 12 is made of EVOH oxygen barrier film material. The outer layer 13 is made of rigid PP material with a thickness of 1mm.

[0041] Specifically, the can 1, composed of an inner layer 11, a middle layer 12, and an outer layer 13, has a certain degree of toughness. When the can 1 is squeezed, the negative pressure inside the can 1 can also discharge liquid food or medicine into the pump body 3 and deliver it to the straw 4, thereby increasing the applicability of the feeding or medicine feeding device.

[0042] Working principle: When the patient uses the feeding or medication applicator, the medical staff presses the pressing head 33. As the pressing head 33 moves, it drives the piston rod 32 and piston plate 31 to move. When the piston plate 31 moves, it squeezes the spring 36. Under the influence of the pressure of the piston plate 31, the gas inside the pump body 3 is discharged through the liquid outlet valve 37. Subsequently, under the reaction of the spring 36, the piston plate 31 pushes the piston rod 32 and the pressing head 33 upward. At this time, the negative pressure inside the pump body 3 causes the liquid outlet valve 37 to close and the liquid inlet valve 34 to open. The liquid food inside the tank 1 enters the pump body 3 through the liquid inlet valve 34. Under continuous pressing, the liquid food inside the pump body 3 is discharged through the liquid outlet valve 37 to the suction tube 4, thus realizing the delivery of liquid food. When the liquid outlet valve 37 is open, the liquid inlet valve 34 automatically closes, which can prevent the problem of liquid food backflow.

[0043] When delivering liquids or medications of different consistency, the flow rate of the liquid within the straw 4 needs to be adjusted to avoid the liquid with a lower consistency flowing too fast, which could cause the patient to choke.

[0044] When adjusting the flow rate of straw 4, medical staff rotate the rotating rod 7. The rotating rod 7 rotates on the limiting ring 5 and moves downward. When the rotating rod 7 rotates, it drives the pressure plate 6 to rotate. The pressure plate 6 is eccentrically designed. When the pressure plate 6 comes into contact with straw 4, the squeezing force of the pressure plate 6 causes straw 4 to deform, thereby adjusting its flow rate.

[0045] When the patient is feeding independently, pressing the canister 1 with their hand causes the canister 1 to deform, and the internal pressure can push the liquid food into the pump body 3. Continuous squeezing can allow the liquid food to enter the straw 4, thus realizing the dual use of the feeding or medication device.

[0046] When cleaning the feeding or medicine dispenser, open the sealing cover 2 and remove the liquid outlet valve 37 connected to the straw 4. Then rotate the pump body 3 to disengage the threads between the sealing cover 2 and the pump body 3. After the pump body 3 is disassembled, pull the straw 4 out of the sealing cover 2. This completes the disassembly of the straw 4 and the pump, thereby improving the cleaning quality and efficiency of the feeding or medicine dispenser.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
