Description

Technical Field

[0001] This utility model relates to the field of nasogastric feeding tube replacement technology, and in particular to a winding device for replacing nasogastric feeding tubes. Background Technology

[0002] Nasogastric feeding tubes are typically made of soft tubes that are inserted through the nasal cavity into the esophagus, stomach, or intestines to deliver liquid or semi-liquid nutrients, such as nutrient solutions, water, and medications, directly into the gastrointestinal tract to meet the patient's nutritional needs. During use, nasogastric feeding tubes need to be replaced regularly to prevent blockage and bacterial infection.

[0003] In the prior art, the patent with authorization announcement number CN 221904860 U discloses a nasogastric feeding tube replacement device. After the feeding tube is rolled up and sent to the designated processing position, the side door is opened by opening the latch lock body and the latch hook body. The winding component inside the storage box can be taken out together with the feeding tube for processing. However, the need to take out the winding component together with the feeding tube for processing increases the cost of use. At the same time, there is no shielding measure on the outside of the rolled-up feeding tube. When moving, the feeding tube is easy to scatter, making its subsequent processing difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a winding device for changing nasogastric feeding tubes. It only requires processing the winding reel and does not require replacing other winding components, thereby reducing the cost of use. It can shield the sides of the feeding tube, thereby preventing the feeding tube from scattering when the winding reel is moved, thus providing a guarantee for its subsequent processing. It can effectively solve the problems in the background art.

[0005] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0006] A nasogastric feeding tube replacement winding device includes a frame, a PLC controller mounted on the side of the frame, a drive mechanism mounted on the inner side of the frame, a support frame fixed to the top of the drive part of the drive mechanism, and a mounting block rotatably connected to the end of the support frame via a rotating shaft. Two rotating shafts are provided, each mounted on a corresponding support frame. A winding reel is detachably connected to the side of the mounting block via a connecting mechanism. A locking bolt is provided on the inner side of the winding reel. A shielding unit is installed on the side of the winding reel. A guide frame is fixed to the front of the frame, with guide holes.

The bidirectional lead screw is rotatably mounted inside the guide groove and is threadedly connected to the transmission seat. The servo motor is mounted on the side of the frame, and the output shaft of the servo motor is fixedly connected to the end of the bidirectional lead screw. The servo motor is electrically connected to the PLC controller.

[0009] Furthermore, the connection mechanism includes a socket and a plug, with the plug fixed to the side of the mounting block and the socket fixed to the side of the reel, the socket and the plug being inserted into each other.

[0010] Furthermore, the shielding unit includes shielding blocks, pressure plates, and positioning grooves.

[0019] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Please see Figure 1-3This embodiment provides a technical solution: a nasogastric feeding tube replacement winding device, including a frame 1, a PLC controller 12 mounted on the side of the frame 1, a drive mechanism 6 mounted on the inner side of the frame 1, a support frame 7 fixed to the top of the drive part of the drive mechanism 6, and a mounting block 9 rotatably connected to the end of the support frame 7 via a rotating shaft 8. Two rotating shafts 8 are provided, each mounted on a corresponding support frame 7. A winding reel 10 is detachably connected to the side of the mounting block 9 via a connecting mechanism 4. A latch 14 is provided on the inner side of the winding reel 10, and a blocking unit 3 is installed on the side of the winding reel 10. The front side of the frame 1 is fixed... A guide frame 2 is provided, and a guide hole 11 is provided on the guide frame 2. A wiping unit 5 is installed on the guide frame 2 at the position corresponding to the guide hole 11. A stepper motor 13 is installed on the side of the support frame 7. The output shaft of the stepper motor 13 is fixedly connected to the end of one of the rotating shafts 8. The PLC controller 12 is electrically connected to the external power supply and the stepper motor 13 respectively. The output shaft of the stepper motor 13 drives the mounting block 9 to rotate through the rotating shaft 8. The mounting block 9 drives the winding reel 10 to rotate through the connecting mechanism 4. One end of the nutrition tube is clamped on the clamp 14. The nutrition tube is guided through the guide hole 11. The winding reel 10 rotates to wind up the nutrition tube.

[0021] The drive mechanism 6 includes a transmission seat 62 and a guide groove 64. The guide groove 64 is formed on the frame 1, and the transmission seat 62 is slidably connected to the guide groove 64. The support frame 7 is fixed on the top of the transmission seat 62. The drive mechanism 6 also includes a servo motor 61 and a bidirectional lead screw 63. The bidirectional lead screw 63 is rotatably mounted inside the guide groove 64 and is threadedly connected to the transmission seat 62. The servo motor 61 is mounted on the side of the frame 1, and the output shaft of the servo motor 61 is fixedly connected to the end of the bidirectional lead screw 63. The servo motor 61 is electrically connected to the PLC controller 12. The connection mechanism 4 includes a socket 41 and a plug 42. The plug 42 is fixed to the mounting block. On the side of 9, the socket 41 is fixed to the side of the take-up reel 10. The socket 41 and the plug 42 are connected. When the take-up reel 10 needs to be removed, the output shaft of the servo motor 61 drives the bidirectional lead screw 63 to rotate. The bidirectional lead screw 63 is threadedly driven by the transmission seat 62. The transmission seat 62 slides along the guide groove 64 and drives the support frame 7 to move, thereby separating the plug 42 from the socket 41, so that the take-up reel 10 can be removed. The take-up reel 10 is easy to install and disassemble, which facilitates subsequent processing. At the same time, only the take-up reel 10 needs to be processed, without the need to replace other take-up components, thereby reducing the cost of use.

[0022] The shielding unit 3 includes shielding blocks 31, pressure plates 32, and positioning grooves 33. The shielding blocks 31 are evenly arranged on the take-up reel 10 and are movably connected to the take-up reel 10. The pressure plates 32 are fixed to the outer ends of the shielding blocks 31. The positioning grooves 33 are opened on the take-up reel 10 and are set one-to-one with the shielding blocks 31. After winding is completed, the pressure plates 32 are pressed down, and the pressure plates 32 drive the shielding blocks 31 to be inserted into the positioning grooves 33. The shielding blocks 31 shield the sides of the feed tubes, thereby preventing the feed tubes on the take-up reel 10 from becoming scattered when the take-up reel 10 is moved, thus providing a guarantee for its subsequent processing.

[0023] The wiping unit 5 includes a connecting seat 51, a wiping cotton ball 52, and a Velcro strap 53. The wiping cotton ball 52 is located inside the connecting seat 51. There are two Velcro straps 53, which are respectively located on the sides of the connecting seat 51 and the guide frame 2. The two Velcro straps 53 are bonded together. During the winding process, the surface of the feed tube is wiped by the wiping cotton ball 52, which is soaked in alcohol. When the wiping cotton ball 52 needs to be replaced, the connecting seat 51 can be removed by tearing the two Velcro straps 53 apart. The cleanliness of the feed tube during the winding process is ensured by wiping the feed tube.

[0024] The working principle of the nasogastric feeding tube replacement winding device provided by this utility model is as follows: The output shaft of the stepper motor 13 drives the mounting block 9 to rotate through the rotating shaft 8. The mounting block 9 drives the winding reel 10 to rotate through the connecting mechanism 4. One end of the feeding tube is clamped on the buckle 14. The feeding tube is guided through the guide hole 11. The winding reel 10 rotates to wind up the feeding tube. After winding, the pressure plate 32 is pressed down. The pressure plate 32 drives the blocking block 31 to be inserted into the positioning groove 33. The blocking block 31 blocks the side of the feeding tube. During the winding process, the surface of the feeding tube is wiped by the wiping cotton ball 52. The wiping cotton ball 52 is a wiping cotton ball soaked in alcohol. When the wiping cotton ball 52 needs to be replaced, the connecting seat 51 can be removed by tearing the two Velcro straps 53 apart.

[0025] When it is necessary to remove the take-up reel 10, the output shaft of the servo motor 61 drives the bidirectional lead screw 63 to rotate. The bidirectional lead screw 63 is threadedly driven by the transmission seat 62. The transmission seat 62 slides along the guide groove 64 and drives the support frame 7 to move, thereby separating the plug 42 from the socket 41, so that the take-up reel 10 can be removed.
