Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to an improved substitute tube-type automatic feeding device. Background Technology

[0002] The concept of rapid recovery is crucial for the nutritional intake of oral cancer patients. Traditionally, oral cancer patients rely on nasogastric tubes for feeding long after surgery. However, this placement can lead to problems such as sore throat, stomach discomfort, resistance to feeding, low comfort, and nutritional imbalances, hindering the recovery of chewing and swallowing functions and impacting postoperative rehabilitation. Replacement tubes are widely used in patients with difficulty opening their mouths after orthognathic surgery or fracture surgery.

[0003] However, the traditional substitute tube consists of a 20 ml syringe connected to the tip of the gastric tube. Because the tip of the gastric tube has a porous design, food in the mouth does not easily accumulate in the pharynx, resulting in low swallowing efficiency. Furthermore, the connection is prone to breakage when the injection pressure is high, which increases the operation risk and patient discomfort.

[0004] Therefore, there is a particular need for an improved substitute tube-type automatic feeding device to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional substitute tubes, which are connected to a 20 ml syringe and a multi-hole gastric tube, resulting in low swallowing efficiency, easy breakage, increased operational risks and patient discomfort, the technical problem to be solved is to provide an improved substitute tube oral automatic feeding device.

[0006] The technical solution of this utility model is: an improved substitute tube-type automatic feeding device, including a syringe, a push rod, an infusion tube, an interface, and a piston block. The push rod is slidably connected inside the syringe and is composed of a cross plate and a circular block. The cross plate is located inside the syringe, and the circular block is located outside the syringe. The piston block is fixed to the end of the push rod, and its side edge is in close contact with the inner wall of the syringe and slides in contact with the syringe. The bottom end of the piston block is in contact with the bottom end of the syringe. The interface is fixed to the center point of the bottom end of the syringe. The infusion tube is inserted outside the interface and is made of a soft material. It also includes a clamping component for clamping the infusion tube, which is set outside the lower end of the syringe.

[0007] In one embodiment, the clamping assembly includes a fixed ring, a first spring, a movable ring, a rotating plate, a locking block, a connecting plate, an inclined column, a guide rod, and a second spring. Both the fixed ring and the movable ring are mounted on the syringe. The fixed ring is fixed to the lower outer end of the syringe, while the movable ring is slidably connected to the lower outer end of the syringe and located below the fixed ring. The first spring is fixed between the fixed ring and the movable ring. Two rotating plates for clamping the infusion tubing are distributed left and right, rotatably connected to the left and right sides of the movable ring. Two locking slots are distributed front and back, one on the left and one on the right. At the bottom of the side rotating plate, two locking blocks are distributed front and back and fixed to the bottom of the right rotating plate. The two locking blocks and two locking slots are locked in one-to-one. The two corners of the locking blocks that are not connected to the right rotating plate are designed as rounded corners. The guide rod is fixed to the left rotating plate. The connecting plate is slidably connected to the outside of the guide rod and contacts the left rotating plate. Two inclined columns are symmetrically distributed and fixed to the bottom of the connecting plate. The locking blocks have circular grooves with the same diameter as the inclined columns. The second spring is fixed between the left rotating plate and the connecting plate and is sleeved on the outside of the guide rod.

[0008] In one embodiment, a sealing plug is also included. The sealing plug is fixed to the outside of the upper end of the infusion tube by an elastic band. The outer diameter of its top end is smaller than the inner diameter of the infusion tube, while the outer diameter of its bottom end is the same as the inner diameter of the infusion tube, so that the sealing plug has a conical structure and is a rubber sealing plug.

[0009] In one embodiment, a sealing ring is also included, the threaded sealing ring being fixed to the outside of the sealing plug, and the outer diameter of the sealing ring being the same as the outer diameter of the sealing plug.

[0010] In one embodiment, a scale line is also included, which is printed on the front side of the syringe exterior.

[0011] In one embodiment, a push plate is also included, which is fixed to the upper left side of the connecting plate, and has a plurality of strip-shaped semi-circular grooves on the side away from the left rotating plate. Beneficial effects

[0012] With its single-hole infusion tube design, fluid food can enter the pharynx more concentratedly, significantly improving swallowing efficiency. At the same time, thanks to the coordinated work of the rotating plate, clamping block, connecting plate, and inclined column, the infusion tube can be firmly clamped to prevent displacement or dislodgement during injection. Even under high injection pressure, the infusion tube remains stable, ensuring the safety and smoothness of the feeding process. Attached Figure Description

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] Example: An improved substitute tube-type automatic feeding device, such as Figures 1-4 As shown, the device includes a syringe 1, a plunger 2, an infusion tubing 3, an interface 4, a sealing plug 5, a sealing ring 6, graduation lines 7, and a piston block 8. The plunger 2 is slidably connected inside the syringe 1 and consists of a cross plate and a circular block. The cross plate is located inside the syringe 1, and the circular block is located outside the syringe 1. The piston block 8 is located at the end of the plunger 2, with its side edge tightly against the inner wall of the syringe 1 and in sliding contact with it. The bottom end of the piston block 8 is in contact with the bottom end of the syringe 1. The piston block 8 is made of medical-grade rubber, which has excellent elasticity and can fit tightly against the inner wall of the syringe 1 to ensure that liquid food does not leak. The interface 4 is located at the center point of the bottom end of the syringe 1. The infusion tubing 3 is sleeved on the outside of the interface 4 and is made of a soft material, such as medical-grade silicone or polyurethane, to minimize oral irritation during insertion and use, while providing good flexibility. For both toughness and comfort, the sealing plug 5 is located on the outer side of the upper end of the infusion tube 3. The outer diameter of its top end is smaller than the inner diameter of the infusion tube 3, while the outer diameter of its bottom end is the same as the inner diameter of the infusion tube 3. The sealing plug 5 has a conical structure, which ensures that when the sealing plug 5 enters the infusion tube 3, the top end can smoothly enter the infusion tube 3 in advance to avoid jamming or resistance. Then the bottom end gradually enters the infusion tube 3 and finally completely blocks the infusion tube 3. The sealing plug 5 is a rubber sealing plug 5. The threaded sealing ring 6 is connected to the outside of the sealing plug 5 by adhesive. Its outer diameter is the same as the outer diameter of the sealing plug 5, which ensures that when the sealing plug 5 blocks the infusion tube 3, the sealing ring 6 is in close contact with the inner wall of the infusion tube 3 to achieve a good sealing effect. The scale line 7 is printed on the front side of the outside of the syringe 1. It also includes a clamping component for clamping the infusion tube 3, which is located on the outer side of the lower end of the syringe 1.

[0020] like Figures 2-4As shown, the clamping assembly includes a fixed ring 9, a first spring 10, a movable ring 11, a rotating plate 12, a locking block 13, a connecting plate 14, an inclined column 15, a guide rod 16, a second spring 17, and a push plate 18. Both the fixed ring 9 and the movable ring 11 are mounted on the syringe 1. The fixed ring 9 is fixedly mounted on the outer side of the lower end of the syringe 1, while the movable ring 11 is slidably connected to the outer side of the lower end of the syringe 1 and located below the fixed ring 9. The fixed ring 9 and the movable ring 11 are connected by the first spring 10. The rotating plate 12 is symmetrically rotated and connected to both sides of the movable ring 11. Two slots 121 are provided at the lower part of the left rotating plate 12, and two locking blocks 13 that match the slots 121 are provided at the lower part of the right rotating plate 12. The locking blocks 13, when engaged with the slots 121, allow the two rotating plates 12 to be fixed together and clamp the infusion tube 3. The locking blocks 13 are not engaged with the right rotating plate 12. The two corners of the connection are rounded, which can effectively prevent jamming when the locking block 13 is engaged with the corresponding locking slot 121. The guide rod 16 is set on the outside of the left rotating plate 12. The connecting plate 14 is slidably connected to the guide rod 16 and contacts the left rotating plate 12. Two inclined columns 15 are set on the side of the connecting plate 14 facing the rotating plate 12. The locking block 13 has a circular groove that matches the inclined column 15. The inclined column 15 can be accurately locked into the corresponding locking block 13 and further fix the left and right rotating plates 12. The left rotating plate 12 and the connecting plate 14 are connected by a second spring 17. The second spring 17 is sleeved on the outside of the guide rod 16. A push plate 18 is set on the upper left side of the connecting plate 14. There are multiple strip semi-circular grooves on the side away from the connecting plate 14, which can provide the force point of the push plate 18 and facilitate stable contact with the push plate 18.

[0021] Initially, the inclined column 15 engages with the corresponding slot on the locking block 13, fixing the two rotating plates 12. The two rotating plates 12 cooperate to clamp the infusion tube 3, preventing the infusion tube 3 from falling off or shifting. At this time, because the rotating plate 12 is abutted by the connection of the infusion tube 3, the first spring 10 is in a stretched state. When the patient needs to eat, the medical staff first inserts the infusion tube 3 into the container containing liquid food, and then slowly pulls the push rod 2 upward, causing the piston block 8 to move upward, creating a negative pressure in the syringe 1, and drawing the liquid food in the container into the syringe 1 through the infusion tube 3. When drawing in, the liquid food passes through the scale line. 7. Read the volume of fluid food to ensure accurate extraction. After extraction, insert the infusion tube 3 into the patient's mouth, positioning the end of the infusion tube 3 at the patient's third molar. Then, slowly push the push rod 2 downwards, causing the piston block 8 to move downwards, pushing the fluid food in the syringe 1 into the patient's mouth through the infusion tube 3. During the feeding process, even if the injection pressure is high, the two rotating plates 12 can firmly clamp the infusion tube 3, effectively preventing the infusion tube 3 from loosening or falling off, ensuring a safe and smooth feeding process. After completing one feeding process, remove the infusion tube 3 from the patient's mouth and repeat the above steps for the next feeding.

[0022] When the infusion tubing 3 needs to be replaced, press the push plate 18 with your finger and push the connecting plate 14 downwards. The second spring 17 is compressed accordingly, and the connecting plate 14 drives the inclined column 15 to move downwards and disengage from the corresponding locking block 13. Then, rotate the two rotating plates 12 outwards to more than 90 degrees to disengage the locking block 13 from the corresponding locking groove 121. Release the two rotating plates 12. At this time, the rotating plate 2 no longer contacts the connection point of the infusion tubing 3. The first spring 10 rebounds and pulls the movable ring 11 towards the fixed ring 9. The movable ring 11 drives the two rotating plates 12 to move upwards, completely releasing the clamping of the infusion tubing 3. Finally... Remove the used IV tubing 3, insert the new IV tubing 3, pull down the movable ring 11 to return the two rotating plates 12 to the height where the IV tubing 3 is fixed, and the first spring 10 will be stretched again. Then rotate the two rotating plates 12 inward to return to the angle used to fix the IV tubing 3 and contact the IV tubing 3. At the same time, the locking block 13 will be locked into the corresponding locking slot 121. After locking, release the connecting plate 14, and the second spring 17 will return to its original state, causing the connecting plate 14 to move upward, which will drive the inclined column 15 to move upward and lock into the corresponding locking block 13, fixing the two rotating plates 12. This completes the replacement process of the IV tubing 3.

[0023] If you cannot eat immediately after replacing the IV tubing 3, you can pull the sealing plug 5 and insert it into the IV tubing 3 to prevent air from entering the IV tubing 3, maintain the sealing state of the IV tubing 3, and ensure that the liquid food will not be contaminated when used next time.
