Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a liquid food feeding device for intensive care nursing. Background Technology

[0002] Feeding is a crucial part of nursing care for critically ill patients. These patients often have weak swallowing abilities and low immunity, making traditional artificial feeding prone to problems such as inaccurate dosage and high risk of contamination. The emergence of specialized liquid feeding devices allows for precise control of infusion rate and dosage, reducing human error and the probability of infection, which is of great significance in ensuring patients' nutritional needs are met. However, if liquid feeding devices are not cleaned promptly, they can have multiple adverse effects, directly threatening the recovery and life safety of critically ill patients. The residual liquid food is rich in nutrients and can quickly breed bacteria, mold, and other microorganisms. These pathogens can easily cause intestinal infections after entering the patient's body with the liquid food. If the device comes into direct contact with the patient's respiratory or digestive tract mucosa, it may also induce serious infections such as pneumonia and stomatitis, worsening the patient's condition. B. After the residual liquid food dries, it will adhere to the inner wall of the tube, gradually causing the tube to narrow or even block, resulting in poor or interrupted liquid food infusion, which cannot meet the nutritional needs of critically ill patients and delays the recovery process. If the same device is used for multiple patients, contaminants remaining in the device that has not been thoroughly cleaned can easily cause cross-infection. Summary of the Invention

[0003] In response to the above situation, the present invention provides a liquid feeding device for intensive care nursing. The cleaning conversion connector of the present invention can be flexibly switched between two states: one is to form a passage to achieve the cleaning function, and the other is to close the liquid inlet tube to assist liquid feeding. While providing a stable feeding function, it can achieve efficient cleaning of the support tube inside the device. Compared with traditional manual disassembly and washing, this cleaning method is more efficient and thorough, which can not only ensure the cleaning effect, but also significantly reduce the risk of infection.

[0004] The technical solution adopted by this invention is as follows: This invention proposes a liquid food feeding device for intensive care nursing, including a cleaning conversion connector, a filling and pushing outer tube, and a liquid food replacement inner tube. The cleaning conversion connector is fixedly connected to the bottom of the filling and pushing outer tube, and the liquid food replacement inner tube is filled into the filling and pushing outer tube. The cleaning conversion connector includes a wrapping support ring, a sliding moving part, and a suction part. The sliding moving part slides within the wrapping support ring, and the suction part is fixedly connected to one side of the wrapping support ring. The filling and pushing outer tube includes a wrapping outer tube and a driving top cover. The driving top cover is threadedly engaged with the top of the wrapping outer tube, and the cleaning conversion connector is fixedly connected to the wrapping outer tube. The liquid food replacement inner tube is engaged with the top of the wrapping outer tube, and the driving top cover is provided with a driving component for pushing out the liquid food.

[0005] Furthermore, the liquid food replacement inner tube includes a replacement tube and a rotating pusher, the rotating pusher being fitted inside the replacement tube, and a tube clamping groove being formed at the bottom of the outer wall of the replacement tube.

[0006] The liquid food replacement inner tube of this invention is filled with a uniformly prepared liquid food, which is prepared through a professional industrial process. While ensuring that the liquid food is delicate and uniform, it can provide patients with a nutritional preparation with a stable nutritional structure. In addition, the replacement tube is made of transparent material and the outer wall is marked with graduations, which makes it easy for caregivers to record and control the patient's food intake, thus providing convenience for the nursing work of medical staff.

[0007] Furthermore, the rotating pusher includes a rotating shaft and a pusher ring. The pusher ring is sleeved and fitted onto the outside of the rotating shaft. The top surface of the rotating shaft has an irregularly shaped groove, and the outer wall of the rotating shaft has a spiral groove. The lower end of the rotating shaft is inserted into a support frame. The inner wall of the pusher ring has a spiral protrusion, and the side wall of the pusher ring has a fixing groove that engages with an inner wall block.

[0008] Preferably, an internal locking block is fixedly connected to the bottom of the inner wall of the outer tube, a bottom connecting tube is fixedly connected to the bottom of the outer tube, and the wrapping support ring is fixedly connected inside the bottom connecting tube.

[0009] The tube slot engages with the internal locking block, the inner wall of the replacement tube is fixedly provided with an inner wall locking block, and a support frame is fixedly provided on the inner wall of the lower end of the replacement tube.

[0010] As a further preferred embodiment of the present invention, the drive top cover includes a rotating cover, the drive component is fixedly disposed inside the rotating cover, the rotating cover is threadedly engaged with the outer tube, the drive component includes a drive motor and a rotating disk, the rotating disk is electrically connected to the drive motor, the drive motor is electrically connected to a power source, and the bottom surface of the rotating disk is fixedly provided with irregularly shaped protrusions.

[0011] Preferably, the wrapping support ring includes an upper support ring and a lower support ring. The lower support ring is fixedly connected to the bottom of the upper support ring. An inlet chamber is fixedly connected to the top of the upper support ring. The bottom surface of the inlet chamber is circumferentially provided with an inlet hole. A guide post is fixedly connected to the lower support ring.

[0012] As a further preferred embodiment of the present invention, the sliding moving component includes a supporting downward moving tube, a dragging component, and a supporting spring. The dragging component is fixedly connected to the upper end of the supporting downward moving tube, the supporting spring is wrapped around the outside of the supporting downward moving tube, an inner wall locking ring is fixedly connected to the inner wall of the supporting downward moving tube, a limiting locking ring is wrapped around the outer wall of the supporting downward moving tube, and guide holes are provided on both sides of the limiting locking ring. The guide post slides within the guide holes.

[0013] The bottom of the support lowering tube proposed in the device of the present invention is connected to the end of the nasogastric tube. After feeding, the nasogastric tube is pulled out, and then the gravity suction head of the suction pump is placed in clean water. The suction pump is turned on to completely clean the area below the retaining ring on the inner wall of the support lowering tube. The cleaned mixed liquid flows out from the lower end of the support lowering tube, thereby achieving thorough cleaning of the inside of the component tube, ensuring the hygiene of the internal environment of the component, and preventing bacterial growth.

[0014] The dragging component includes a dragging ring, dragging columns, and a shielding ring. The dragging ring is fixedly connected to the upper end of the supporting downward tube. Multiple dragging columns are fixedly connected to the top surface of the dragging ring in a circumferential shape. A shielding soft ring is fixedly connected to the upper end of the dragging column. The shielding ring is fixedly connected to the upper end of the dragging column. A leakage hole is provided in a circumferential shape on the shielding ring. The supporting spring is mounted between the bottom surface of the dragging ring and the top surface of the lower supporting ring.

[0015] The diameter of the drag column in the device of this invention is smaller than the diameter of the inlet hole, providing a flow path for the clean liquid. When the inner tube of the liquid food replacement is inserted into the outer tube of the filling pusher, the sliding moving part is pushed down by the bottom of the replacement tube until the shielding soft ring completely blocks the gap between the drag column and the inlet hole. The bottom of the inlet tube is sealed, so that the clean conversion connector is in a completely sealed state, avoiding leakage of clean liquid or gas mixing during feeding, preventing foreign matter from entering the liquid food and causing quality degradation, which in turn causes patient discomfort.

[0016] Furthermore, the suction component includes a suction pump, a connecting horizontal pipe, and a suction pipe. One end of the connecting horizontal pipe is connected to the liquid inlet pipe, and the other end of the connecting horizontal pipe is connected to the suction pump. The suction pipe is fixedly installed at the lower end of the suction pump. A one-way valve plate is fixedly installed inside the connecting horizontal pipe, and a gravity suction head is fixedly installed at the lower end of the suction pipe.

[0017] The suction pump component proposed in this invention draws external liquid and pumps it into the inlet chamber. The suction pump component pumps external cleaning liquid into the inlet chamber, and the liquid flows into the support lowering pipe through the inlet hole to flush its inner wall, thereby achieving cleaning of the support lowering pipe after use.

[0018] Furthermore, the device of the present invention is electrically connected to the control device. The drive motor (the core component of the drive top cover) is regulated by the control device, which can adjust the speed to control the liquid infusion rate. The suction pump is linked with the control device, and the cleaning time and liquid flow rate can be set by the control device to ensure the cleaning effect. Since the control program and electronic components required by the control device are all existing technologies, and the existing technologies can already achieve the above-mentioned technical effects, they will not be described in detail here.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The liquid food replacement inner tube of the present invention is filled with uniformly prepared liquid food, which is prepared through a professional industrial process. While ensuring that the liquid food is delicate and uniform, it can provide patients with a nutritional preparation with a stable nutritional structure. In addition, the replacement tube is made of transparent material and the outer wall is marked with graduations, which makes it easy for caregivers to record and control the patient's food intake, and provides convenience for the nursing work of medical staff.

[0020] (2) The bottom of the support lowering tube proposed in the device of the present invention is connected to the end of the nasogastric tube. After feeding, the nasogastric tube is pulled out, and then the gravity suction head of the suction pump is placed in clean water. The suction pump is turned on to completely clean the area below the locking ring on the inner wall of the support lowering tube. The cleaned mixed liquid flows out from the lower end of the support lowering tube, thereby achieving thorough cleaning of the component tube, ensuring the hygiene of the internal environment of the component, and preventing bacterial growth.

[0021] (3) The diameter of the drag column proposed in the device of the present invention is smaller than the diameter of the liquid inlet hole, providing a flow path for the clean liquid. When the liquid food replacement inner tube is inserted into the filling push outer tube, the sliding moving part is pushed down by the bottom of the replacement tube until the shielding soft ring completely blocks the gap between the drag column and the liquid inlet hole. The bottom of the liquid inlet tube is sealed, so that the clean conversion connector is in a completely sealed state, avoiding leakage of clean liquid or gas mixing during feeding, preventing foreign matter from entering the liquid food and causing quality degradation, which in turn causes discomfort to the patient.

[0022] (4) The suction pump component proposed in the device of the present invention draws external liquid and pumps it into the liquid inlet tube. The suction pump component pumps external cleaning liquid into the liquid inlet tube. The liquid flows into the support lowering tube through the liquid inlet hole and washes its inner wall, thereby achieving cleaning of the support lowering tube after use.

The supporting spring 18 is mounted between the bottom surface of the dragging ring 22 and the top surface of the lower supporting ring 12.

[0032] The suction component 6 includes a suction pump component 27, a connecting horizontal pipe 28, and a suction pipe 30. One end of the connecting horizontal pipe 28 is connected to the inlet chamber pipe 13, and the other end of the connecting horizontal pipe 28 is connected to the suction pump component 27. The suction pipe 30 is fixedly installed at the lower end of the suction pump component 27. A one-way valve plate 29 is fixedly installed inside the connecting horizontal pipe 28, and a gravity suction head 31 is fixedly installed at the lower end of the suction pipe 30. The filling and pushing outer tube component 2 includes a wrapping outer tube 7 and a drive top cover 8. The drive top cover 8 is threadedly engaged at the top of the wrapping outer tube 7, and the cleaning conversion connector 1 is fixedly installed inside the wrapping outer tube 7.

[0033] An internal locking block 32 is fixedly connected to the bottom of the inner wall of the outer tube 7, and a bottom connecting tube 33 is fixedly connected to the bottom of the outer tube 7. The supporting ring 4 is fixedly connected inside the bottom connecting tube 33.

[0034] The drive top cover 8 includes a rotating cover 34, and a drive component 35 is fixedly installed inside the rotating cover 34. The rotating cover 34 is threadedly engaged with the outer tube 7. The drive component 35 includes a drive motor 36 and a rotating disk 37. The rotating disk 37 is electrically connected to the drive motor 36, and the drive motor 36 is electrically connected to a power source. The bottom surface of the rotating disk 37 is fixedly provided with a shaped protrusion 38.

[0035] The liquid food replacement inner tube 3 includes a replacement tube 9 and a rotating pusher 10. The rotating pusher 10 is engaged inside the replacement tube 9. A tube slot 39 is provided at the bottom of the outer wall of the replacement tube 9. The tube slot 39 engages with an internal locking block 32. An inner wall locking block 40 is fixedly connected to the inner wall of the replacement tube 9. A support frame 41 is fixedly connected to the inner wall of the lower end of the replacement tube 9.

[0036] The rotating pusher 10 includes a rotating shaft 42 and a pusher ring 43. The pusher ring 43 is sleeved and fitted on the outside of the rotating shaft 42. The top surface of the rotating shaft 42 is provided with an irregular groove 44. The outer wall of the rotating shaft 42 is provided with a spiral groove 45. The lower end of the rotating shaft 42 is inserted into the support frame 41. The inner wall of the pusher ring 43 is provided with a spiral protrusion 46. The side wall of the pusher ring 43 is provided with a fixing groove 47, which engages with the inner wall locking block 40.

[0037] In practical use, the bottom of the outer tube 7 is connected to the nasogastric tube, the control device is connected to the power supply, the control device is electrically connected to the drive motor 36, and the control device is signal connected to the suction pump 27. During use, the outer tube 7 and the rotating cover 34 of the drive top cover 8 are separated by rotation to obtain the liquid food replacement inner tube 3. The sterile sealing cap at the bottom of the replacement tube 9 is removed and inserted into the outer tube 7. The tube slot 39 and the internal locking block 32 are aligned and locked, making the replacement tube 9 and the outer tube 7 relatively stable. The replacement tube 9 is locked with the inner locking block 32 of the outer tube 7 through the tube slot 39, which not only achieves axial fixation and prevents the replacement tube 9 from shifting during feeding, but also restricts the rotation of the replacement tube 9, ensuring that the fixing slot 47 of the push ring 43 is always locked with the inner wall locking block 40, avoiding transmission failure. The irregular protrusion 38 at the bottom of the rotating cover 34 is engaged with the irregular groove 44 at the top of the rotating shaft 42, and then tightened in the opposite direction. During the tightening process, the rotating disk 37 is not fixed when the drive motor 36 is in the off state, and the rotating disk 37 and the rotating shaft 42 are relatively fixed. The bottom of the replacement tube 9 engages with the inner wall engaging ring 19 of the lower moving tube 16. The pushing sliding moving part 5 moves down inside the wrapping support ring part 4. The dragging part 17 moves down inside the liquid inlet tube 13 inside the upper support ring 11. The dragging column 23 slides and moves inside the liquid inlet hole 14 until the blocking soft ring 24 completely blocks the gap space between the liquid inlet hole 14 and the dragging column 23. The guide hole 21 of the limiting engaging ring 20 slides along the guide column 15 of the lower support ring 12. The support spring 18 placed between the dragging ring 22 and the lower support ring 12 is compressed. At this time, the filling work is completed.

[0038] During the feeding stage, the drive motor 36 is activated by the control device, and the rotating disk 37, which is electrically connected to the drive motor 36, begins to rotate, causing the rotating shaft 42 to rotate. The spiral groove 45 engages with the spiral protrusion 46 on the inner wall of the push ring 43, and the fixing slot 47 of the push ring 43 engages with the inner wall locking block 40. While the rotating shaft 42 rotates, the push ring 43 slowly moves down, pushing the liquid food into the nasogastric tube. After the feeding is completed, the outer tube 7 is first separated from the nasogastric tube, and then the drive top cover 8 is rotated to separate it. The amount of liquid food discharged is recorded according to the scale feedback of the replacement tube 9. The replacement tube 9 is then removed. Under the reset action of the support spring 18, the dragging component 17 is reset, and the top surface of the shielding ring 25 contacts the top surface of the liquid inlet tube 13, opening the passage between the dragging column 23 and the liquid inlet hole 14.

[0039] During the cleaning stage, the gravity suction head 31 of the suction tube 30 is placed into the cleaning liquid. The suction pump 27 is turned on by the control device. The suction pump 27 draws the cleaning liquid into the connecting horizontal tube 28 and then fills the inlet chamber tube 13 through the one-way valve plate 29. The one-way valve plate 29 controls the one-way flow of the cleaning liquid and prevents reverse flow. As the liquid in the inlet chamber 13 increases, it impacts and drags the ring 22 downward, causing the cleaning liquid to be discharged from the inlet hole 14. This cleans the food residue in the support lower tube 16, and the mixed liquid flows out from the lower end of the support lower tube 16.

[0040] The above is the overall workflow of this invention. Simply repeat this process the next time you use it.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
