Description

Technical Field

[0001] The invention relates to the technical field of a delivery tube regulating structure of an insulin intravenous pump, in particular to an auxiliary device for an insulin intravenous pump. Background Art

[0002] When the insulin intravenous pump is in working state, the mechanical system of the pump receives instructions from the control system, drives the piston close to the rear end of the medicine reservoir, and injects insulin into the subcutaneous tissue through the infusion tube connected to the medicine reservoir, where it is absorbed by the blood to exert its blood sugar-lowering effect.

[0003] The delivery tube on the existing insulin intravenous pump is generally equipped with an auxiliary device to adjust the delivery tube. However, the delivery tube is wound on the auxiliary device. During the process of winding and adjusting the position or length of the delivery tube, the delivery tube is wound tightly on the auxiliary device (as the insulin intravenous pump is used for a long time), making the winding and adjustment inconvenient.

[0004] To this end, we propose an auxiliary device for an insulin intravenous pump. Summary of the invention

[0005] The object of the present invention is to provide an auxiliary device for an insulin intravenous pump to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides an auxiliary device for an insulin intravenous pump, comprising a pump body and an adsorption disk that fits the skin, the pump body being provided with a delivery tube, the end of the delivery tube being connected with an implant that communicates with the adsorption disk; and also comprising a matching disk, the matching disk being rotatably connected with a fixed cylinder that is wound around the delivery tube, the fixed cylinder being movably engaged with two staggered movable rings that are movable with the delivery tube, a movable groove being provided on the fixed cylinder, a rotating rod being slidably engaged in the movable groove, a movable ball being fixedly connected to the bottom of the rotating rod, a pressure plate being fixedly connected to the rotating rod, and a sleeve that is connected and fixed to the movable ring being movably engaged with the rotating rod; a movable assembly, the movable assembly being used to enable the rotating rod to move along the movable groove to loosen the delivery tube, and to fix the fixed cylinder to the matching disk, and then the rotating rod that is self-rotating and tilted makes the two movable rings move away from each other, thereby loosening the delivery tube again;

[0007] When the rotating rod that is perpendicular to the matching disk rotates, the two movable rings rotate at their original positions, and the movable rings and the conveying pipes move, thereby facilitating adjustment of the uniform distribution of the conveying pipes on both sides of the matching disk.

[0008] Furthermore, the movable component includes a self-rotating disk rotatably connected to the matching disk, the self-rotating disk is fixed to the port of the fixed cylinder, the central axis of the self-rotating disk is fixedly connected to the spherical shell, the movable ball is movably embedded in the spherical shell, the outer surface of the spherical shell is fixedly connected to a limiting ring plate, and there is a gap between the middle of the self-rotating disk and the middle of the matching disk.

[0009] Furthermore, the movable component also includes a plurality of pressure rods arranged in a rectangular shape and passing through the limit ring plate and the rotating disk. The top end of the pressure rod is spherical and is pressed and matched with the pressure plate, and the bottom end of the pressure rod is pressed and matched with the matching disk. The contact surfaces between the pressure rod and the matching disk are friction surfaces, and a pull rope is passed through the pressure rod.

[0010] Furthermore, sliding grooves are provided on both sides of the fixed cylinder, and a slide plate is slidably fitted in the sliding groove, and two ends of the slide plate are respectively connected and fixed to the movable ring and the sleeve.

[0011] Furthermore, a sliding column is fixedly connected inside the sleeve, and inclined grooves that are symmetrically distributed on the rotating rod and slidably cooperate with the sliding column are provided, so that the two sleeves can move away from or approach each other at the same time.

[0012] Furthermore, an elastic rubber ring is fixedly connected to the bottom of the pressing rod and presses against the matching disk.

[0013] Furthermore, a plug-in rod is inserted at the top of the rotating rod, an elastic puller is hung between one end of the plug-in rod and the rotating rod, and the other end of the plug-in rod is fixedly connected to an adjustment handle that is pressed and matched with the fixed tube, so as to facilitate operation.

[0014] Furthermore, a first semicircular plate is fixedly connected to the top of the fixed cylinder, and a second semicircular plate is movably fitted inside the first semicircular plate and rotatably fitted with the movable ring located at a lower position; a third semicircular plate is fixedly connected to the rotating disk, and a fourth semicircular plate is movably fitted inside the third semicircular plate and rotatably fitted with the movable ring located at an upper position; the end of the second semicircular plate is pressed against the fourth semicircular plate to increase the protective performance.

[0015] Furthermore, the pressure rod is rotatably connected to a lower pressure plate that is in contact with the pressure plate through a first torsion spring, and a slide groove is provided on the rotating disk. A support plate that is inclined and presses against the matching disk is rotatably connected to the lower pressure plate through a second torsion spring. The support plate moves in the slide groove, which increases the supporting effect and prevents one side of the matching disk from tilting and rising when the rotating rod is tilted, thereby affecting the adhesion effect between the matching disk and the skin.

After the adjustment is completed, the rotating rod is relaxed to make it vertical, and the rotating rod is rotated to make the fixed cylinder and the movable ring rotate synchronously, thereby not changing the length of the conveying pipe wound on the outer surface of the fixed cylinder, and only adjusting the length between the adsorption disk and the matching disk and the length between the matching disk and the pump body to ensure the appropriate and reasonable distribution of the length of the conveying pipe.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When adjusting the loosening or tightening of the conveying tube, the rotating rod is rotated along the movable groove to tilt the rotating rod, so that the fixed tube and the rotating disk are fixed in position. At this time, the two movable rings are tilted to move the conveying tube wound on the outer surface of the fixed tube. Then, the tilted state of the rotating rod is maintained, and the rotating rod is rotated in this state, so that the two movable rings move away from or close to each other, thereby further moving the conveying tube wound on the fixed tube. This method is convenient and quick to operate when the conveying tube on the movable fixed tube is loosened or tightened.

[0023] After the adjustment is completed, the rotating rod is loosened so that the rotating rod and the matching disk are distributed vertically, and then the rotating rod is rotated to make the fixed cylinder rotate, and the movable ring rotates synchronously. The length of the delivery pipe wound on the fixed cylinder remains unchanged, and the delivery pipe is only moved along the fixed cylinder and the movable ring, thereby adjusting the length of the delivery pipe section between the adsorption disk and the matching disk and the delivery pipe section between the matching disk and the pump body to ensure the appropriate and reasonable distribution of the delivery pipe length. This method is convenient and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Embodiment 1

[0042] See also Figure 1-Figure 10 The present invention provides an auxiliary device for an insulin intravenous pump, comprising a pump body 1 and an adsorption disk 2 that fits the skin, wherein a delivery tube 3 (a rubber tube) is arranged on the pump body 1, and an implant 4 that communicates with the adsorption disk 2 is connected to the end of the delivery tube 3; the pump body 1 also comprises a matching disk 5, wherein a fixed cylinder 6 that is wound around the delivery tube 3 is rotatably connected to the matching disk 5, and two movable rings 7 that are staggered and movable with the delivery tube 3 are movably matched on the fixed cylinder 6, and an movable groove 8 is provided on the fixed cylinder 6, and a rotating rod 9 is slidably matched in the movable groove 8, and an movable ball 10 is fixedly connected to the bottom of the rotating rod 9, and the rotating rod 9 is rotated. The movable rod 9 is fixedly connected with a pressing plate 29, and the rotating rod 9 is movably matched with a sleeve 11 connected and fixed with the movable ring 7; the movable assembly is used to make the rotating rod 9 move along the movable groove 8 to loosen the conveying pipe 3, and fix the fixed cylinder 6 with the matching disk 5, and then rotate the inclined rotating rod 9 to make the two movable rings 7 move away from each other, and loosen the conveying pipe 3 again; when the rotating rod 9 rotates perpendicular to the matching disk 5, the two movable rings 7 rotate in the original position, and the movable ring 7 and the conveying pipe 3 move, so as to facilitate the adjustment of the uniform distribution of the conveying pipe 3 on both sides of the matching disk 5;

[0043] An operating method of an auxiliary device for an insulin intravenous pump, using the above-mentioned auxiliary device for an insulin intravenous pump, the specific operating method includes the following steps;

[0044] S1. First, the adsorption disk 2 is adsorbed on the patient's skin, and the matching disk 5 is adhered to the skin. Finally, the pump body 1 is placed in the pocket, thereby completing the installation of the insulin intravenous pump and using it.

[0045] S2. When adjusting the looseness or tightening of the conveying tube 3, the rotating rod 9 is rotated along the movable groove 8 to tilt the rotating rod 9, so that the fixed cylinder 6 and the rotating disk 12 are fixed in position, and the two movable rings 7 are tilted, so as to loosen the conveying tube 3 wound on the outer surface of the fixed cylinder 6;

[0046] S3, further adjustment, keep the rotating rod 9 in an inclined state, and rotate the rotating rod 9, so that the two movable rings 7 move toward each other, so as to further move the conveying pipe 3 wound on the fixed cylinder 6. This method is convenient and quick to operate by facilitating the loosening or tightening of the conveying pipe 3;

[0047] S4. After the adjustment is completed, relax the rotating rod 9 to make it vertical, and rotate the rotating rod 9 to make the fixed cylinder 6 and the movable ring 7 rotate synchronously, so as not to change the length of the conveying pipe 3 wound on the outer surface of the fixed cylinder 6. Only the length between the adsorption disk 2 and the matching disk 5 and the length between the matching disk 5 and the pump body 1 are adjusted to ensure the appropriate length of the conveying pipe 3 and its reasonable distribution.

[0048] The operating steps of the present application are as follows: first, adsorb the adsorption plate 2 onto the patient's skin (the preferred infusion and implantation site is the abdomen, followed by the upper arm, outer thigh, lower back, buttocks, etc., depending on the actual situation of the patient), then stick the matching plate 5 (the bottom surface of the matching plate 5 has an adsorption and sticky effect) to a nearby position, and finally place the pump body 1 in the pocket to complete the installation of the insulin intravenous pump and use it.

[0049] During use, when adjusting the looseness or tightening of the delivery tube 3 (such as the length of the delivery tube 3 between the matching disk 5 and the pump body 1 needs to be adjusted), the delivery tube 3 wound on the fixed cylinder 6 needs to be loosened first, and the rotating rod 9 is rotated along the movable groove 8 to tilt the rotating rod 9, so that the fixed cylinder 6 and the self-rotating disk 12 are fixed in position (corresponding to the matching disk 5, and no relative rotation occurs). At this time, the two movable rings 7 are tilted to move the delivery tube 3 wound on the outer surface of the fixed cylinder 6;

[0050] Then, the rotating rod 9 is kept in an inclined state, and the rotating rod 9 is rotated in this state. The rotating rod 9 rotates relative to the fixed cylinder 6, so that the two movable rings 7 move away from or close to each other, thereby further moving the delivery tube 3 wound on the fixed cylinder 6. This method allows the delivery tube 3 on the movable fixed cylinder 6 to be easily and quickly operated when loosening or tightening the delivery tube 3.

[0051] After the adjustment is completed, the delivery pipe section between the adsorption disk 2 and the matching disk 5 is not compatible with the delivery pipe section between the matching disk 5 and the pump body 1 (the lengths of the two delivery pipe sections are not appropriate, such as one is tight and the other is loose). By loosening the rotating rod 9, the rotating rod 9 is vertically distributed with the matching disk 5. At this time, the fixed cylinder 6 and the self-rotating disk 12 and the matching disk 5 are movable and rotated with each other;

[0052] Then, the rotating rod 9 rotates to make the fixed cylinder 6 rotate, and the movable ring 7 rotates synchronously. The movable ring 7 will not move along the sliding groove 17, that is, the length of the delivery pipe 3 wound on the fixed cylinder 6 remains unchanged, and the delivery pipe 3 is only moved along the fixed cylinder 6 and the movable ring 7, so as to adjust the length of the delivery pipe section between the adsorption disk 2 and the matching disk 5 and the delivery pipe section between the matching disk 5 and the pump body 1, thereby ensuring the appropriate and reasonable distribution of the length of the delivery pipe 3. This method is convenient and simple to operate.

[0053] The movable component includes a rotating disk 12 rotatably connected to the matching disk 5. The rotating disk 12 is fixed to the end of the fixed cylinder 6. The central axis of the rotating disk 12 is fixedly connected to the spherical shell 13. The movable ball 10 is movably embedded in the spherical shell 13. The outer surface of the spherical shell 13 is fixedly connected to a limiting ring plate 14. There is a gap between the middle of the rotating disk 12 and the middle of the matching disk 5.

[0054] The movable assembly also includes a plurality of pressure rods 15 arranged in a rectangular shape and penetrating the limit ring plate 14 and the rotating disk 12. The top of the pressure rod 15 is spherical and presses against the pressure plate 29. The bottom of the pressure rod 15 presses against the matching disk 5. The contact surfaces of the pressure rod 15 and the matching disk 5 are both friction surfaces. A pull rope 16 runs through the pressure rod 15.

[0055] Sliding grooves 17 are provided on both sides of the fixed cylinder 6, and a sliding plate 18 is slidably fitted in the sliding groove 17. Both ends of the sliding plate 18 are respectively connected and fixed to the movable ring 7 and the sleeve 11;

[0056] During loosening adjustment: when the rotating rod 9 is tilted along the sliding groove 17, the movable ball 10 moves in the spherical shell 13, and the movable ball 10 will not be separated from the spherical shell 13. At this time, the pressing plate 29 is tilted along the rotating rod 9, and the tilted pressing rods 15 press on individual pressing rods 15, so that the pressing rods 15 move vertically downward and press and fix on the matching disk 5, so that the fixed cylinder 6 and the rotating disk 12 do not rotate relative to the matching disk 5;

[0057] When individual pressing rods 15 move downward, the pull ropes 16 passing through the pressing rods 15 cause the adjacent pressing rods 15 to move downward synchronously, further ensuring the stable fit between the fixing tube 6 and the matching plate 5;

[0058] Then, the pressing rod 15 is kept in an inclined state and rotated by itself. The inclined pressing rod 15 drives the pressing plate to rotate synchronously and in an inclined manner without changing the stable cooperation between the fixed cylinder 6 and the matching plate 5. The fixed cylinder 6 does not rotate, and the rotating inclined rotating rod 9 makes the movable ring 7 move away or approach synchronously, thereby completing the further loosening of the conveying pipe 3.

[0059] After the adjustment is completed, loosen the rotating rod 9 so that the rotating rod 9 is perpendicular to the matching disk 5. At this time, the pressing rod 15 is away from the matching disk 5, so that the fixed cylinder 6 can move relative to the matching disk 5, and then rotate the rotating rod 9 to make the fixed cylinder 6 and the movable ring 7 rotate synchronously. The movable ring 7 does not move along the sliding groove 17, thereby not changing the length of the conveying pipe 3 wound on the outer surface of the fixed cylinder 6. Only the length of the conveying pipe section between the adsorption disk 2 and the matching disk 5 and the length of the conveying pipe section between the matching disk 5 and the pump body 1 are adjusted to ensure the appropriate length and reasonable distribution of the conveying pipe 3.

[0060] A plug-in rod 22 is inserted into the top of the rotating rod 9, and an elastic puller 23 is hung between one end of the plug-in rod 22 and the rotating rod 9. The other end of the plug-in rod 22 is fixedly connected to an adjusting handle 24 that presses against the fixed tube 6. When the rotating rod 9 is tilted along the sliding groove 17, the elastic puller 23 is subjected to force by pulling the adjusting handle 24, which is easy to operate. When the rotating rod 9 is not tilted, the adjusting handle 24 is not pulled. Under the action of the elastic puller 23, the rotating rod 9 is maintained in a non-tilted state and the rotating rod 9 is rotated.

[0061] A sliding column 19 is fixedly connected inside the sleeve 11, and inclined grooves 20 that slide with the sliding column 19 are symmetrically distributed on the rotating rod 9. The rotating inclined rotating rod 9 cooperates with the non-rotating fixed cylinder 6, and under the action of the inclined groove 20 and the sliding column 19, the two fixed sleeves 11 and the movable ring 7 move away from or towards each other synchronously.

[0062] The bottom of the pressing rod 15 is fixedly connected with an elastic rubber ring 21 that presses against the matching disk 5. The pressing rod 15 moves vertically downward, and the elastic rubber ring 21 that contacts the matching disk 5 is deformed first, thereby ensuring the pressing and fixing between the pressing rod 15 and the matching disk 5 (the pressing rod 15 and the matching disk 5 are not in contact at this time). Then the pressing rod 15 continues to move downward, on the one hand, increasing the fixing effect of the elastic rubber ring 21 and the matching disk 5, and on the other hand, making the pressing rod 15 contact with the matching disk 5, further strengthening the pressing and fixing effect. Thus, the rotating disk 12 and the fixed cylinder 6 do not rotate.

[0063] The two movable rings 7 are inclined, and the distance between the movable rings 7 and the fixed tube 6 is relatively large, so the inclined movable rings 7 will not enter the sliding grooves 17 .

[0064] Embodiment 2

[0065] See also Figure 1 and Figure 11-13A first semicircular plate 25 is fixedly connected to the top of the fixed cylinder 6, and a second semicircular plate 26 is movably fitted inside the first semicircular plate 25 and rotatably fitted with the movable ring 7 located at the lower position. A third semicircular plate 27 is fixedly connected to the turntable 12, and a fourth semicircular plate 28 is rotatably fitted with the movable ring 7 located at the upper position inside the third semicircular plate 27, and the end of the second semicircular plate 26 is pressed against the fourth semicircular plate 28.

[0066] In the present application, when the movable rings 7 move away from or approach each other, the second semicircular plate 26 moves inside the first semicircular plate 25, and the fourth semicircular plate 28 moves inside the third semicircular plate 27, thereby ensuring that clothing and the like do not touch and affect the conveying tube 3 wound on the fixed cylinder 6, thereby increasing the protective effect.

[0067] Embodiment 3

[0068] See also Figure 1-Figure 6 and Figure 14-15 The pressing rod 15 is rotatably connected to a lower pressing plate 30 that contacts the pressing plate 29 through a first torsion spring, a slide groove 31 is provided on the rotating disk 12, and a support plate 32 that is obliquely distributed and contacts the matching disk 5 is rotatably connected to the lower pressing plate 30 through a second torsion spring, and the support plate 32 moves in the slide groove 31;

[0069] In this embodiment, when the pressing plate 29 is tilted, it first presses one of the lower pressing plates 30, and then presses the pressing rod 15 connected to the lower pressing plate 30;

[0070] The lower pressure plate 30 first rotates downward to make the support plate 32 move downward at an angle, thereby pressing against the matching disk 5. The support plate 32 supports the pressing effect to prevent the matching disk 5 from tilting when the rotating rod 9 is tilted, causing one side of the matching disk 5 to detach from the skin, thereby ensuring the adhesion effect between the matching disk 5 and the skin.
