Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a rotary insulin abdominal injection rotation positioning card. Background Art

[0002] Insulin therapy is one of the important means to achieve good blood sugar control. Local nodules and subcutaneous fat hyperplasia after insulin injection are common complications of insulin therapy. Rotation of injection sites is an effective prevention method. This rotation includes rotation between different injection sites and rotation within the same injection site. The "Technical Guidelines for Diabetes Drug Injection in China (2016 Edition)" points out that although more than 90% of patients claim to have rotated injection sites, only 15% of patients have the correct rotation method. There are currently a variety of insulin rotation injection methods, but due to design defects or complex operating procedures, the actual feasibility is poor and it is difficult to implement for a long time.

[0003] Chinese patent publication number CN211935066U discloses a similar insulin injection positioning device, including a positioning sticker, which is a multi-layer disc-shaped structure, including a protective layer, a base layer and a pattern layer arranged between the protective layer and the base layer, and the pattern layer is provided with a stamp-type injection mark for marking the insulin injection position. When the protective layer is removed, the injection mark on the pattern layer can be transferred to the patient's skin.

[0004] However, the above device cannot fix the patient's needle when in use, so the needle may shake during the injection, and the injection position cannot be automatically recorded after the injection is completed, making the device difficult to use for the elderly or people with poor memory and having low applicability. Summary of the invention

[0005] The present invention aims to overcome the shortcomings of the above-mentioned prior art that the needle of the patient cannot be fixed during use, which may cause the needle to shake during the injection of the patient, and the injection position cannot be automatically recorded after the injection is completed, making the device difficult to use for the elderly or people with poor memory and having low applicability.

[0006] A rotary insulin abdominal injection rotation positioning card is proposed, comprising a fixed plate, a rotating plate for adjusting the injection position, a rotating assembly for preventing the rotating plate from reversing, a horizontal bubble for ensuring the accuracy of the injection position, an injection assembly for fixing the needle, a locking assembly for preventing the rotating plate from rotating suddenly, a screw for adjusting the position of the injection assembly and a reminder assembly for reminding the patient, wherein the rotating plate is rotatably arranged inside the fixed plate, the rotating assembly is vertically arranged below the rotating plate, the rotating plate is connected to the fixed plate through the rotating assembly, the horizontal bubble is horizontally arranged on the top of the fixed plate and connected to a preset groove of the fixed plate, the injection assembly is located on one side of the rotating plate and is slidably connected to the rotating plate, multiple groups of locking assemblies are all arranged inside the fixed plate, and the locking assembly is connected to the rotating plate, the screw is rotatably arranged inside the rotating plate, and the screw is located on one side of the injection assembly and is connected to the injection assembly, and the reminder assembly is arranged on the other side of the injection assembly and connected inside the rotating plate.

[0007] In the technical solution of the present invention, when the patient is undergoing an injection, the clamping block of the injection assembly can clamp and fix the syringe by itself, thereby fixing the position of the needle, thereby preventing the needle from shaking during the patient's injection, and after the injection assembly slides to the injection position, the injection assembly will drive the rotating shell of the reminder assembly to rotate, so that different colors leak out from the rotating shell, and record the injection position by itself, so as to solve the problem mentioned in the technical background that the patient's needle cannot be fixed during use, so the patient's needle may shake during the injection, and the injection position cannot be automatically recorded after the injection is completed, resulting in the device being difficult for the elderly or people with poor memory to use and having low applicability.

[0008] Preferably, the fixing plate is provided with a hollow injection area, and a plurality of slots for filling in dates are provided on the fixing plate, a placement slot for placing a cotton swab is provided on the back of the fixing plate, and a flap is connected to the top of the placement slot, and the flap is bonded to the fixing plate. Therefore, when the cotton swab needs to be taken out, the cotton swab can be taken out directly, and the sterilized cotton swab can be used to disinfect the injection area after being taken out, which is more convenient for the patient.

[0009] Preferably, the rotating assembly is vertically connected to the center of the fixed plate, and the rotating assembly will press against the rotating plate when the rotating plate rotates in the opposite direction, thereby avoiding repeated injection in the same area.

[0010] Preferably, the rotating assembly includes a fixed cylinder, a rotating cylinder, a shell, a ratchet and a first spring.

The ratchet is slidably connected inside the shell, and one end of the ratchet passes through the rotating cylinder and engages with the slot. There are two groups of first springs, both of which are arranged at the other end of the ratchet. Both ends of the two groups of first springs are respectively connected to the ratchet and the shell. After the rotating plate rotates forward, the ratchet will use the fixed cylinder to resist the rotating plate and the rotating cylinder by itself, thereby preventing the rotating plate from rotating in the opposite direction.

[0011] Preferably, an injection groove is opened transversely on the rotating plate, and the injection assembly is slidably arranged inside the injection groove. After the rotating plate rotates, the patient can rotate the injection area in a planned manner according to the rotating injection groove, thereby avoiding duplication of injection sites.

Two sliding plates are respectively arranged on both sides of the moving block and are hinged on the moving block. The box body is connected to the top of the moving block. There are two clamping blocks, both of which are slidably arranged inside the box body. A pressure rod is connected to each group of clamping blocks. There are two groups of second springs, which are respectively arranged on the outsides of the two groups of clamping blocks, and the two ends of the two groups of second springs are respectively connected to the clamping block and the box body. The bolt is connected to one side of the sliding plate and conflicts with the box body. Before the needle is injected, the clamping block will clamp the syringe by itself to prevent the needle from shaking during injection.

[0013] Preferably, one sliding plate is connected to a sliding table, the sliding table is connected to a screw rod, and another sliding plate is connected to a rack, the rack is meshed with a reminder component, and a scale line is provided on the sliding plate above the rack. When the rack moves, it drives the rotating shell to rotate, thereby reminding the patient which position to inject, so as to avoid repeated injections at the same position.

[0014] Preferably, the reminder component includes a fixed shell, a worm wheel, a worm and a rotating shell. The fixed shell is connected to the inside of the rotating plate. The worm is rotatably connected to the inside of the fixed shell and is arranged on one side of the fixed shell. There are three worm wheels, all of which are rotatably connected to the inside of the fixed shell, and the three worm wheels are meshed with the worm. A rotating shell is arranged above each turbine, and each rotating shell is rotatably connected to the fixed shell. The rotating plate is provided with openings at the positions of the three rotating shells, and four reminder areas are provided on the turbine. Therefore, after the patient rotates the rotating plate to the next position, the worm can be used to uniformly adjust the reminder colors of the three worm wheels, thereby avoiding the patient having to move the injection assembly to the initial position before the injection can be performed.

[0015] Preferably, the worm wheel has four reminder areas, and the rotating shell is provided with an observation hole, so that the patient can observe the reminder color on the worm wheel through the observation hole before injection, thereby helping the patient to quickly distinguish the injection area.

[0017] Compared with the prior art, the present invention has the following beneficial effects: During the process of a patient injecting insulin or when the needle needs to stay under the skin after the injection, the injection assembly of the present invention will clamp the syringe to fix the needle, thereby preventing the needle from shaking during injection and falling from under the skin. At the same time, when injecting insulin, the injection assembly can guide the needle, and the injection assembly can be rotated according to usage requirements to change the injection angle of the needle. After the patient completes the injection, the reminder assembly can change the reminder color automatically under the push of the injection assembly, thereby automatically recording the injection position to avoid the patient from repeating the injection at the same position.

DETAILED DESCRIPTION

[0019] The following will be combined with the attached embodiment of the present invention Figure 1-29 , the technical solutions in the embodiments of the present invention are described in detail.

[0020] like Figure 1-3 As shown, a rotary insulin abdominal injection rotation positioning card comprises a fixed plate 1, a rotating plate 2 for adjusting the injection position, a rotating component 3 for preventing the rotating plate 2 from reversing, a horizontal bubble 4 for ensuring the accurate injection position, an injection component 5 for fixing the needle, a locking component 6 for preventing the rotating plate 2 from rotating suddenly, a screw rod 7 for adjusting the position of the injection component 5 and a reminder component 8 for reminding the patient, a groove is opened inside the fixed plate 1, and the rotating plate 2 is rotatably arranged inside the groove.

[0021] like Figure 1-3 As shown, a hollow injection area is provided on the fixed plate 1, and the patient can inject insulin through the injection area. A slot 13 for filling in the date is provided on the fixed plate 1. The injection area on the fixed plate 1 is divided into four parts, and each part is divided into seven parts. Therefore, a paper strip with a date can be attached to the inside of the slot 13 to help the patient distinguish the date. A locking component 6 is provided at the position of each slot 13 on the fixed plate 1.

[0022] like Figure 1-3As shown, after the rotating plate 2 rotates to the position of each date, the locking component 6 will jam the rotating plate 2 to prevent the rotating plate 2 from continuing to rotate. The rotating component 3 is vertically arranged below the rotating plate 2 and at the center of the fixed plate 1, and the rotating component 3 is connected to the fixed plate 1. The rotating plate 2 is connected to the fixed plate 1 through the rotating component 3. Therefore, after the rotating plate 2 rotates forward on the fixed plate 1, the rotating component can prevent the rotating plate 2 from reversing.

[0023] like Figure 1-3 As shown, the horizontal bubble 4 is horizontally arranged above the fixing plate 1, and the fixing plate 1 is provided with a groove at the position of the horizontal bubble 4. The horizontal bubble 4 is bonded in the preset groove. When the patient is injected, the center of the fixing plate 1 is placed at the navel position, and the fixing plate 1 is rotated until the horizontal bubble 4 is in a horizontal position and then stops rotating. Then the rotating plate 2 can be rotated to the date of injection, thereby ensuring the accuracy of the injection position to avoid multiple injections at the same position.

[0024] like Figure 1-3 As shown, an injection groove 2121 is horizontally opened on one side of the rotating plate 2, and the injection component 5 is slidably set inside the injection groove 2121 and clamped on the rotating plate 2. Therefore, when the rotating plate 2 rotates, the injection component 5 will drive the synchronous rotation. The total length of the injection groove 2121 is divided into three parts, corresponding to the injection positions three times a day, so the horizontal bubble 4 on the fixed plate 1 remains horizontal. After the rotating plate 2 rotates to the corresponding date, the injection component 5 can be slid to the corresponding injection position.

[0025] like Figure 1-3 As shown, the screw rod 7 is rotatably connected to the inside of the rotating plate 2, and the screw rod 7 is located on one side of the injection assembly 5 and is threadedly connected to the injection assembly 5. Therefore, when the injection assembly 5 needs to slide to change the injection position, the screw rod 7 can be rotated forward or reversely to change the injection position of the injection assembly 5. The screw rod 7 has a self-locking property. Therefore, after the screw rod 7 slides the injection assembly 5 to the desired position, the screw rod 7 does not rotate and the injection assembly 5 will not move at will.

[0026] like Figure 1-3 As shown, the reminder component 8 is arranged on the other side of the injection component 5 and connected to the inside of the rotating plate 2. After the injection component 5 slides to the desired position inside the injection groove 2121, the reminder component 8 will remind the patient that the injection component 5 has slid to the desired injection position, thereby eliminating the need to continue sliding. After the patient is injected, the reminder component 8 will remind the patient that the injection has been completed at this position, thereby avoiding the patient from injecting the same position on the same day.

[0027] like Figure 4-8As shown, a placement groove 11 for placing a sterilized cotton swab is vertically opened on the back of the fixed plate 1, and a flap 12 is connected above the placement groove 11. After the flap 12 is opened, the cotton swab inside the placement groove 11 can be taken out, and then the injection area can be disinfected. The flap 12 is made of a plastic material with elastic deformation ability (such as TPU or EPDM), and one end of the flap 12 is bonded to the fixed plate 1, so the flap 12 can rotate with its bonding point with the fixed plate 1 as the center of the circle, thereby opening or closing the placement groove 11.

[0028] like Figure 4-8 As shown, the other end of the flip cover 12 is clamped on the fixed plate 1 through an umbrella-shaped block preset on the fixed plate 1, so that the flip cover 12 can be easily opened and closed when needed without causing trouble to the patient. The fixed plate 1 is provided with a set of locking components 6 at the position of each slot 13, and the shift rod 62 of the locking component 6 passes through the fixed plate 1 and is arranged on the inner side of the fixed plate 1. Therefore, when the rotating plate 2 rotates to the desired date, the shift rod 62 will be inserted into the preset groove of the rotating plate 2, thereby preventing the rotating plate 2 from continuing to rotate.

[0029] like Figure 9-13 As shown, the injection assembly 5 includes a moving block 51, a sliding plate 52, a box body 53, a clamping block 54, a pressure rod 55, a second spring 56 and a bolt 57. There are two sliding plates 52 vertically arranged on both sides of the moving block 51, and the two sliding plates 52 are connected to the moving block 51. The sliding plate 52 is slidably arranged inside the injection groove 2121, and the screw rod 7 is threadedly connected to a slide preset on a sliding plate 52. Therefore, when the screw rod 7 rotates and uses the slide to drive the sliding plate 52 to slide, the sliding plate 52 will drive the moving block 51 to rotate synchronously.

[0030] like Figure 9-13 As shown, since the moving block 51 is hinged on the sliding plate 52, the moving block 51 can rotate on the sliding plate 52, thereby changing the angle between the moving block 51 and the rotating plate 2, and then changing the injection angle of insulin. An injection hole is opened at the center of the moving block 51. The moving block 51 can be made of a hard material (such as polypropylene or polyethylene). When the needle is inserted into the injection hole of the moving block 51, the injection hole can guide the needle, thereby ensuring that the needle does not shake when it is inserted into the abdomen.

[0031] like Figure 9-13 As shown, one sliding plate 52 is connected to a slide and is connected to the screw rod 7 through the slide, while the other sliding plate 52 is provided with scale lines, and arrows are provided on the box body 53 at the position of the scale lines. Therefore, when the moving block 51 drives the box body 53 to rotate, the rotation angle of the moving block 51 can be observed through the arrow on the box body 53, and the bolt 57 is arranged below the scale line and is threadedly connected to the sliding plate 52, and one end of the bolt 57 passes through the sliding plate 52 and contacts the box body 53.

[0032] like Figure 9-13 As shown, after the moving block 51 has completed its rotation, the bolt 57 can be rotated in the forward direction until the end of the bolt 57 contacts the box body 53, so that the box body 53 and the moving block 51 can be fixed. A rack 58 is provided under the bolt 57, and the rack 58 is bonded to the sliding plate 52. Therefore, the sliding plate 52 can drive the rack 58 to move together when it moves, and the rack 58 is engaged with the rotating shell 84 of the reminder component 8. Therefore, when the rack 58 moves to the position of the rotating shell 84, the rack 58 will drive the rotating shell 84 to rotate together.

[0033] like Figure 14-18 As shown, the box body 53 is arranged above the moving block 51 and bonded to the moving block 51, so the moving block 51 will drive the box body 53 to move together when it moves or rotates. There are two clamping blocks 54, both of which are slidably arranged inside the box body 53, and the two clamping blocks 54 are respectively on both sides of the box body 53. A pressure rod 55 is bonded to each clamping block 54, one end of the pressure rod 55 is bonded to the clamping block 54, and the other end of the pressure rod 55 passes through the box body 53 and is arranged on the outside of the box body 53.

[0034] like Figure 14-18 As shown, when the pressure rod 55 is pressed, the pressure rod 55 will drive the clamping block 54 to move together. Two second springs 56 are respectively arranged on the outsides of the two groups of clamping blocks 54. The two groups of second springs 56 are both arranged at the center position of the clamping block 54, and the two ends of the two second springs 56 are respectively clamped on the clamping block 54 and the box body 53. Therefore, when the pressure rod 55 is pressed to drive the clamping block 54 to move toward the side plate of the box body 53, the clamping block 54 will squeeze the second spring 56. At this time, the second spring 56 will undergo elastic deformation and accumulate force.

[0035] like Figure 14-18 As shown, when the pressure rod 55 is released, the second spring 56 will rebound the two groups of clamping blocks 54 to their original positions. A through hole is provided on the top plate of the box body 53, and an injection hole is provided on the bottom plate of the box body 53. The through hole on the top plate of the box body 53 and the injection hole on the bottom plate coincide with the axis of the injection hole on the moving block 51. Two clamping blocks 9 are also provided inside the box body 53. The two clamping blocks 9 are respectively arranged under the two groups of clamping blocks 54 and connected to the preset grooves on the bottom plate of the box body 53, and the two clamping blocks 9 are made of plastic with elastic deformation (such as TPU or EPDM).

[0036] like Figure 14-18As shown, the top of the card block 9 is in conflict with the clamping block 54. Therefore, when the pressure rod 55 is pressed to move the two clamping blocks 54 toward the side plate of the box body 53, until the clamping block 54 moves to the rear of the pressure rod 55, the card block 9 will pop up to clamp the clamping block 54 to prevent it from being popped out by the second spring 56. However, when the syringe is inserted into the interior of the box body 53 and the needle is inserted into the injection hole and moves downward, the syringe will squeeze the card block 9 downward until the card block 9 is pressed into the preset groove. At this time, the second spring 56 can pop the clamping block 54 outward.

[0037] like Figure 14-18 As shown, at this time, the clamping block 54 can clamp the syringe and thus fix the needle to prevent the needle from shaking during injection. After the insulin is injected, the needle needs to remain in the skin for a period of time. After the clamping block 54 clamps the syringe, it can prevent the needle from falling or shaking during the time it remains stationary.

[0038] like Figure 19-23 As shown, the reminder component 8 includes a fixed shell 81, a worm wheel 82, a worm 83 and a rotating shell 84. The fixed shell 81 is arranged on one side of the injection component 5 and is bonded to a preset groove of the rotating plate 2. The worm 83 is rotatably connected to the inside of the fixed shell 81 and is arranged on one side of the fixed shell 81. The worm 83 is meshed with the worm wheel 82, so the worm 83 can drive the worm wheel 82 to rotate when it rotates. There are three worm wheels 82, all of which are arranged inside the fixed shell 81, and the three worm wheels 82 are rotatably connected to the bottom plate of the fixed shell 81.

[0039] like Figure 19-23 As shown, the three worm gears 82 represent the injection positions of three injections in one day respectively. When the injection assembly 5 moves to the position of the worm gear 82, the injection can be carried out. Four reminder areas are provided on each worm gear 82. The four reminder areas have red and green colors for reminder respectively. Red represents that the injection has been made, and green represents that the injection has not been made. Therefore, the patient can determine the injection position according to the color displayed by the worm gear 82. A rotating shell 84 is provided above each worm gear 82.

[0040] like Figure 19-23 As shown, the rotating shell 84 is rotatably connected to the fixed shell 81, and each rotating shell 84 is provided with a quarter hollow area serving as an observation hole, and a rotating shell 84 is provided at the position of each rotating shell 84 on the rotating plate 2, so that the patient can directly observe the color of the reminder area of ​​the worm gear 82 at this time through the observation holes on the rotating plate 2 and the rotating shell 84, and the outer wall of the rotating shell 84 is provided with a groove 13 similar to teeth, and the teeth on the outer wall of the rotating shell 84 can mesh with the rack 58 on the sliding plate 52.

[0041] like Figure 19-23As shown, when the rack 58 slides forward, it can drive the rotating shell 84 to rotate. When the patient has not completed the injection, the hollow area of ​​the rotating shell 84 is at the upper right corner of the worm wheel 82 and the color displayed by the worm wheel 82 is green (as shown in FIG. Fig.21 ), and then when the patient completes the insulin injection and slides the injection assembly 5, the rack 58 drives the rotating shell 84 to rotate, and at this time the hollow area of ​​the rotating shell 84 rotates to the upper right corner of the worm gear 82 (such as Fig. 22 ).

[0042] like Figure 19-23 As shown, the area displayed by the worm wheel 82 is red, indicating that the injection has been completed at this position. After the rotating plate 2 rotates to the next date, the worm 83 can be rotated, so that the worm wheel 82 is driven by the worm 83 to rotate forward, while the position of the rotating shell 84 is kept unchanged at this time (the position of the rotating shell 84 at this time is as shown in FIG. Fig. 22 ), rotate the green area on the worm wheel 82 to the hollowed-out position of the rotating shell 84, thereby indicating that this position can be injected.

[0043] like Figure 19-23 As shown, when the injection assembly 5 changes the injection position, the rack 58 drives the rotating shell 84 to rotate (until the rotating shell 84 is rotated to the position shown in FIG. Fig.21 The position of the rotating shell 84 is shown until the red color is exposed, which indicates that the injection has been completed at this position. After the injection is completed three times a day, the worm gear 82 and the worm gear 82 can be rotated in the opposite direction. At this time, the rotating shell 84 does not move (the position of the rotating shell 84 is shown in FIG. Fig.21 ), the green reminder area is rotated back to the hollow area of ​​the rotating shell 84, and the process is repeated to remind the patient whether insulin has been injected at the injection site.

[0044] like Figure 24-26 As shown, the rotating assembly 3 includes a fixed cylinder 31, a rotating cylinder 32, a shell 33, a ratchet 34 and a first spring 35. The fixed cylinder 31 is vertically arranged at the center position of the fixed plate 1 and is transferred to the fixed plate 1, and a plurality of groups of card grooves are opened on the inner wall of the fixed plate 1. The rotating plate 2 is vertically arranged inside the fixed cylinder 31, and the top end of the fixed cylinder 31 is bonded to the rotating plate 2. Therefore, when the rotating plate 2 rotates, it will drive the rotating cylinder 32 to rotate synchronously. The shell 33 is arranged inside the rotating cylinder 32 according to the length direction of the rotating cylinder 32 and is bonded to the rotating cylinder 32.

[0045] like Figure 24-26As shown, when the rotating cylinder 32 rotates, it will drive the shell 33 to rotate synchronously. The ratchet 34 is slidably set inside the shell 33 and clamped on the shell 33, and the ratchet 34 is engaged with the clamping groove on the inner wall of the fixed cylinder 31. Therefore, when the rotating cylinder 32 drives the ratchet 34 to rotate, the ratchet 34 will be resisted by the clamping groove and slide toward the inside of the shell 33. There are two first springs 35 and both are set inside the shell 33, and the two first springs 35 are respectively set at both ends of the ratchet 34, and the two ends of the two first springs 35 are respectively clamped on the shell 33 and the ratchet 34.

[0046] like Figure 24-26 As shown, when the ratchet 34 is moved toward the inside of the shell 33 by the groove, the ratchet 34 will squeeze the first spring 35. At this time, the first spring 35 will undergo elastic deformation and begin to accumulate force. Therefore, when the ratchet 34 moves to the inside of the next groove, the first spring 35 will pop out the ratchet 34. Due to the shape of the ratchet 34 and the groove, the rotating plate 2 can only drive the rotating cylinder 32 to rotate forward, and when the rotating plate 2 drives the rotating cylinder 32 to rotate reversely, it will be resisted by the ratchet 34 and cannot rotate, thereby preventing the rotating plate 2 from reversing and causing confusion in the injection area.

[0047] like Figure 27-29 As shown, the locking assembly 6 includes a fixed box 61, a shift rod 62, a push plate 63, a ball 64 and a third spring 65. The fixed box 61 is bonded to a preset groove of the fixed plate 1. The shift rod 62 is slidably arranged inside the fixed box 61, and one end of the shift rod 62 passes through the fixed box 61 and the fixed plate 1 and is arranged in the inner circle of the fixed plate 1. The injection groove 2121 of the rotating plate 2 is located at the position of the shift rod 62 and a groove is opened. The ball 64 is located at one end of the shift rod 62 and is embedded in the end of the shift rod 62, and the ball 64 can rotate on the shift rod 62, and the ball 64 is in contact with the rotating plate 2.

[0048] like Figure 27-29 As shown, the rotating plate 2 will drive the ball 64 to rotate synchronously when rotating, and the third spring 65 is located at the other end of the gear rod 62 and is arranged inside the fixed box 61, and the two ends of the third spring 65 are respectively clamped on the rotating plate 2 and the fixed box 61. Therefore, when the groove at the injection groove 2121 position of the rotating plate 2 is rotated to the position of the gear rod 62, the third spring 65 will pop out the gear rod 62 until the gear rod 62 and the ball 64 are bounced into the inside of the groove. At this time, the rotating plate 2 can no longer rotate, thereby preventing the rotating plate 2 from rotating suddenly during injection.

[0049] like Figure 27-29As shown, the push plate 63 is slidably arranged above the gear rod 62 and is connected to the gear rod 62. After the insulin injection for the day is completed, the push plate 63 can be used to slide the gear rod 62 horizontally until the gear rod 62 is taken out from the groove, and the rotating plate 2 can be rotated again. When the push plate 63 slides the gear rod 62 horizontally, the gear rod 62 will squeeze the third spring 65. At this time, the third spring 65 will undergo elastic deformation and accumulate force until the rotating plate 2 rotates to this position next time, and then the gear rod 62 will be bounced into the interior of the rotating plate 2 again.

[0050] The movement process of this embodiment is to rotate the rotating plate 2 until the injection groove 2121 rotates to the required date and the gear lever 62 is inserted into the groove, then the screw can be rotated to move the injection assembly 5 to the required injection position. After moving to the required position, the flip cover 12 can be opened and the sterile cotton swab can be pulled out. After the injection area is disinfected with the sterile cotton swab, the fixed plate 1 can be placed on the abdomen, and the center position of the fixed plate 1 can be placed on the navel, and the horizontal bubble 4 can be kept horizontal.

[0051] The needle can be inserted into the injection hole of the movable block 51, and insulin can be injected after the syringe presses the card block 9 into the interior of the box body 53 and the clamping block 54 clamps the syringe. After the insulin injection is completed and the needle remains in the skin for a period of time, the pressure rod 55 can be pressed to open the clamping block 54, and then the needle can be pulled out. After the three injections in one day have been completed, the push plate 63 can be used to pull the gear lever 62 out of the rotating plate 2, and then the rotating plate 2 is rotated to the next date and the gear lever 62 is inserted into the interior of the rotating plate 2.

[0052] The worm 83 can be rotated forward to adjust the display color of the worm wheel 82, and the injection component 5 can be injected. The injection component 5 can slide back and forth inside the injection groove 2121 to perform injection.

[0053] The above embodiments are only for illustrating the technical idea of ​​the present invention, and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
