Detailed implementation mode

[0033] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0034] Embodiment 1, as Figures 1 - 9 shown, for a non-slip and anti-aspiration nasogastric tube of the present invention, tube body 1, an airbag 4 is installed on the outer wall of tube body 1, a flow rate adjusting part 2 is installed at the top of tube body 1, an air guide part 3 is installed on one side of tube body 1, the air guide part 3 is connected to the airbag 4 through a conduit on the inner wall of tube body 1, a positioning part 5 is also installed on the outer wall of tube body 1, the air guide part 3 includes an air guide tube 31 connected to one side of tube body 1, one end of the air guide tube 31 is connected to the airbag 4 through a conduit on the inner wall of tube body 1, a piston 32 is hermetically slidably installed in the inner wall of the air guide tube 31, a hollow screw 33 is rotatably connected to one side of the piston 32, and two guide rods 37 passing through the slide holes of the air guide tube 31 are fixed on the side wall of the piston 32, the hollow screw 33 is threadedly docked with the threaded opening of the air guide tube 31 and the thread groove 34 at the end of the air guide tube 31, one end of the air guide tube 31 is connected with a plastic rod 35 through an elastic cord, and the groove on one side of the hollow screw 33 can insert the plastic rod 35 to form engagement.

[0035] By designing the air guiding part 3, during use, the tube body 1 is lubricated. Then, the tube body 1 is inserted downward along one side of the nostril. When it is inserted into the pharynx, the head of the patient with swallowing disorder is lifted so that the mandible is close to the manubrium sterni to facilitate the smooth passage of the tube body 1. Then, the plastic rod 35 is inserted into the groove of the hollow screw 33. The plastic rod 35 is designed with splines and can be engaged with the spline groove of the hollow screw 33. At the same time, only half of the plastic rod 35 is in the groove of the hollow screw 33. Then, the hollow screw 33 rotates and displaces in the thread groove 34 and moves into the inside of the air duct 31. At the same time, the two guide rods 37 slide in the slide holes of the air duct 31, and the piston 32 cannot rotate and displace, so that the gas inside the air duct 31 enters the airbag 4 through the conduit on the inner wall of the tube body 1, and the airbag 4 presses on the tracheal wall, which can play the effect of preventing aspiration. Then, the plastic rod 35 is pulled out. At the same time, such operation is very delicate, and at this time, the hollow screw 33 is located inside the thread groove 34, and the airbag 4 is not easily affected by the outside world to cause air inflation or air leakage, and the stability is very high. It should be noted that there are arrow tips indicating the direction on the outside of the air duct 31. The air duct 31 is made of hard plastic, and a scale table can be set on the outside of the air duct 31, which are all existing design means.

[0036] A cylindrical sleeve 36 is fixed on one side of the air duct 31. The cylindrical sleeve 36 is penetrated and fixedly connected by the thread groove 34, and a plastic cover 38 can be sleeved on the outer wall of the cylindrical sleeve 36, and the guide rod 37 is located inside the cylindrical sleeve 36.

[0037] Furthermore, after the air guiding operation of the airbag 4 is completed, the plastic cover 38 can be inserted outside the cylindrical sleeve 36, which can then play a very good dust-proof role.

[0038] One end of the plastic rod 35 is connected to an elastic cord, and one end of the elastic cord is designed as a loop and is sleeved at the contraction position where the air duct 31 is docked with the side wall of the tube body 1.

[0039] Furthermore, after the air guiding operation of the airbag 4 is completed, the loop at one end of the elastic cord can be sleeved at the contraction port position of the air duct 31 to prevent the position of the plastic rod 35 from being lost, which is more convenient for subsequent use.

[0040] Embodiment 2: The flow rate adjusting part 2 includes an adjusting block 21 fixed at one end of the tube body 1. One side of the adjusting block 21 is hermetically and rotatably connected to an adjusting disk 22, and a part of the adjusting disk 22 passes through the groove. Two through ports communicating with the groove are provided at the upper and lower ends of the adjusting block 21. The upper through port is docked with a tube head for docking a medicine bag, and the lower through port is docked with the tube body 1. Six contraction ports 23 are annularly arranged and distributed on the adjusting disk 22. The contraction ports 23 can be sequentially docked with the two through ports of the groove by rotation. The upper and lower openings of the six contraction ports 23 are the same as those of the through ports, and the size of the internally contracted flow channels gradually changes according to the arrangement.

[0041] By designing the flow regulating part 2, when performing tube feeding, the thumb contacts a part of the side wall of the groove through the regulating disc 22, rotates the regulating block 21, so that a constriction 23 corresponds to the upper and lower openings. Then, connect the food bag outlet to the tube head. Then, the constriction 23 can introduce food into the tube body 1 through the upper and lower openings. However, the widths of the vertical parts in the middle of each constriction 23 are different. Then, the flow rate can be adjusted by adjusting the correspondence between different constrictions 23 and the openings. In this way, the adjustment accuracy is higher, the verticality of the flow rate can be accurately adjusted, and the stability is very good. The flowing liquid food from top to bottom will not affect the regulating disc 22.

[0042] One side of the regulating block 21 is rotatably connected to a semi-circular plastic shell 27. The plastic shell 27 can cover a part of the groove through which the regulating disc 22 passes inside. A magnetic block 271 can be provided in the groove at the other end of the plastic shell 27.

[0043] Furthermore, after the plastic shell 27 rotates and closes to contact the side wall of the regulating block 21, it covers the outer part of the regulating disc 22, thereby further improving the protection effect. In addition, a very small magnetic block 271 can be provided at the other end of the plastic shell 27 relative to the rotation point, and a metal sheet can be provided at the contact point between the regulating block 21 and the magnetic block 271. The position of the plastic shell 27 can be limited through the existing design, which is very practical.

[0044] The bottom rotating shaft of the regulating disc 22 is butted with a positioning disc 24. The positioning disc 24 is located in the inner cavity below the groove of the regulating block 21. A positioning bead 25 slides in the slideway at the bottom of the inner cavity. A first spring 26 is connected between the bottom of the positioning bead 25 and the slideway. Six ball grooves for the positioning bead 25 to embed are annularly provided at the bottom of the positioning disc 24, and the ball grooves correspond to the distribution of the constrictions 23.

[0045] Furthermore, whenever a constriction 23 corresponds to the two openings of the groove of the regulating block 21, the positioning bead 25 will embed into the ball groove at the bottom of the positioning disc 24. When switching, it is necessary to rotate the regulating disc 22 forcefully, and the positioning bead 25 is pressed down to compress the first spring 26. When the next constriction 23 corresponds to the two openings of the groove of the regulating block 21, the positioning bead 25 is inserted into the ball groove again. In this way, equidistant rotation is achieved, ensuring that each rotation has a constriction 23 that can be in a suitable conveying position, and making the positioning disc 24 more stable and not easily shaken by external influences. It should be noted that the equidistant rotation of the positioning bead 25 and the first spring 26 is an existing design.

[0046] The side wall of the regulating disc 22 is designed to be anti-slip. Digital labels 28 are provided on one side of each constriction 23 at the top of the regulating disc 22.

[0047] The digital labels 28 can be marked with Arabic numerals and are arranged in a ring for incrementing, which can facilitate medical staff to select a constriction 23 with a suitable flow rate for the delivery of liquid food, which is very convenient.

[0048] Embodiment 3. The positioning part 5 includes an adjusting sleeve 51 sleeved outside the tube body 1. Slide rods 55 are slidably arranged on both sides of the adjusting sleeve 51. A clamping plate 52 is fixed at the inner end of the slide rod 55 located in the adjusting sleeve 51. Sliding blocks 53 are fixed on both sides of the clamping plate 52. The sliding blocks 53 slide in the inner slideway of the adjusting sleeve 51. A second spring 54 is connected between the sliding block 53 and the inner wall of the slideway. The slide rod 55 is designed as a round rod, and a clamping block 56 can be engaged with the round rod. The clamping block 56 can be attached to the rod head at one end of the slide rod 55. At this time, the clamping plate 52 is in an unclamped state. A skin-friendly pad 59 is bonded to the contact surface between the adjusting sleeve 51 and the skin. Magic tape strips 57 are arranged on both sides of the adjusting sleeve 51, and a sponge sleeve 58 is sleeved on the tape strips.

[0049] By designing the positioning part 5, in the initial state, the two clamping plates 52 clamp the tube body 1. After the airbag 4 is inflated, the slide rod 55 is pulled outwards, and the second spring 54 is compressed. The clamping block 56 is clamped on the part of the slide rod 55 outside the adjusting sleeve 51. At this time, the clamping block 56 can be attached to the rod head at one end of the slide rod 55 to prevent it from resetting. Then, the adjusting sleeve 51 is moved to the upper lip, and the magic tape strip 57 is wound around the back of the head and fastened. The clamping block 56 is removed, and the second spring 54 drives the sliding block 53 to reset, so that the two clamping plates 52 clamp the tube body 1 again. This design is more stable and easier to operate compared with the traditional slot design. The skin-friendly pad 59 makes the contact surface between the adjusting sleeve 51 and the skin more comfortable. At the same time, the sponge sleeve 58 contacts the cheek after being fastened, which can prevent the magic tape strip 57 from pressing and hurting the cheek. It should be noted that the operation steps of the invention are as follows: first, insert the tube, inflate through the air guiding part 3 after the airbag 4 reaches the throat position, bind the positioning part 5 after the intubation is completed to prevent falling off, and finally adjust the flow rate with the flow rate adjusting part 2 when delivering food.

[0050] Enlightened by the above ideal embodiments according to the present invention, through the above description, relevant staff can make various changes and modifications completely within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
