Description

Technical Field

[0001] The present invention relates to the technical field of medical inventions, and in particular to a needle storage and assisting device. Background Art

[0002] Insulin is the only hormone in the body that lowers blood sugar and promotes the synthesis of glycogen, fat, and protein. Exogenous insulin is primarily used to treat diabetes. Patched insulin pumps require a stable and reliable injection of medication via an indwelling needle. After the needle is inserted subcutaneously by the needle-assist device, the needle must be removed from the body and disposed of by the patient.

[0003] For example, Chinese utility model CN201840723U proposes an insulin pump needle insert. This insert can be used to insert an infusion line with a flexible tube into the subcutaneous insulin pump. Insulin pump users can use this insert to replace the relatively painful and unreliable manual insertion of an infusion line needle. This utility model relates to consumables used in insulin pumps in medical products. It includes a main spring, a locking spring, a handle, an outer shell, an inner core, and a locking latch. The handle is mounted on the upper portion of the outer shell, the main spring is mounted on the inner core and placed within the outer shell, the locking spring is mounted on the locking latch, the locking latch is mounted on both sides of the inner core, and the inner core is mounted within the outer shell.

[0004] This utility model uses a needle assist device to insert a steel needle and a soft needle into the patient's subcutaneous tissue together, and then the patient manually pulls the steel needle out of the body. At this time, the patient needs to dispose of the steel needle by himself, discarding the steel needle in a special sharps box or wrapping the steel needle and throwing it into a trash can. If the patient uses the needle while traveling and it is impossible to carry a sharps box with him, he can only choose to wrap the steel needle tightly and then throw it into the trash can, which is very inconvenient.

There is an annular groove 401 on the injection needle body 4 and a needle withdrawal hook 601 on the needle storage box 6. During this step, the needle withdrawal hook 601 is engaged with the annular groove 401.

[0145] like Figure 21 As shown, there is a matching slot 400 on the main body of the applicator 41 and a matching buckle 4001 on the main body seat 1 of the needle assisting device, and the two are fixed by combining the matching slot 400 and the matching buckle 4001.

[0146] The needle assisting device main body 1 is first combined with the applicator 41 and then continues to move downward. When the needle storage box 6 is completely close to the bottom surface of the needle assisting device main body 1, the upward movement of the needle assisting device main body 1 stops.

[0147] During this process, the first main body shell 1a and the needle assisting device main body seat 1 begin to combine, but there is still a certain distance between them.

[0148] According to actual conditions, the injection needle box 5 may not be used, and the applicator 41 may be directly and manually installed to the corresponding position of the needle assisting device.

[0149] Step three, such as Figures 24-25 As shown, the needle-assisting structure and the applicator 41 have been perfectly installed. In this step, the applicator 41 needs to be tightly attached to the patient's skin, wherein:

[0150] The control panel 15 and the panel of the counter cover 18 are separated by a certain distance and continue to increase. One end of the first elastic member 10 is close to the control panel 15, and the other end is close to the upper surface of the first cross-section plate 81 of the columnar enclosure 8. In addition, the sixth clamping protrusion 1811 of the counter cover 18 is matched with the counting matching member 180, and one end of the third elastic member 19 is connected to the baffle, and the other end is connected to the bottom surface of the auxiliary member 83.

[0151] The distance between the needle storage box 6 and the needle assisting device main seat 1 remains unchanged. One end of the second elastic member 11 is connected to the lower surface of the first cross-section plate 81 of the columnar enclosure 8, and the other end is connected to the bottom surface of the auxiliary member 83.

[0152] The first transmission ring 12 , the second transmission ring 13 and the third transmission ring 14 cooperate normally. The inner surface of the first transmission ring 12 cooperates with the outer surface of the second transmission ring 13 , and the outer surface of the third transmission ring 14 cooperates with the inner surface of the second transmission ring 13 .

[0153] The limiting ring 82 on the cylindrical enclosure 8 is close to the auxiliary part 83, and there is a certain distance between them, and the distance gradually decreases until it is 0. Since the outer diameter of the auxiliary part 83 is larger than the outer diameter of the limiting ring 82, when the distance between the two is 0, no relative movement will occur.

[0154] In this step, the needle assist device main body 1 is pressed down by the control chopping board 15 , and the first engaging protrusion 211 moves downward, thereby disengaging from the rib 160 . In this state, the first engaging protrusion 211 is located below the rib 160 .

[0155] The bottom end of the support member 20 cooperates with the second clamping protrusion 611 , and the distance between them is shortened to zero. In addition, there is a certain distance between the bottom end of the support member 20 and the needle assisting device main body 1 .

[0156] At the same time, the injection needle body 4 is combined with the needle storage part 61 so that the injection needle body 4 is fixed.

[0157] refer to Figures 26-27 On the other hand, the needle storage box 6, the needle assisting device main seat 1, the first transmission ring 12, the second transmission ring 13, and the third transmission ring 14 move downward together, and the distance between the bottom surface of the first main shell 1a and the needle assisting device main seat 1 gradually shrinks to zero. At this time, the surface of the applicator 41 is flush with the surface of the first main shell 1a and is placed on the patient's skin.

[0158] Step 4: Figures 28-29 As shown, the state shown in the figure is that the needle insertion is completed, and the injection needle body 4 needs to be pulled out of the patient's skin. The injection needle body 4 begins to be pulled out by the needle withdrawal hook 601, and the applicator 41 needs to remain on the patient's skin surface, wherein:

[0159] The panel distance between the control panel 15 and the counter cover 18 is reduced, but the Arabic numerals of the skylight 151 continue to be exposed for the user's reference. One end of the first elastic member 10 is close to the control panel 15, and the other end is close to the upper surface of the first cross-section plate 81 of the columnar enclosure 8. In addition, the sixth clamping protrusion 1811 of the counter cover 18 is matched with the counting matching member 180, and one end of the third elastic member 19 is connected to the baffle 191, and the other end is connected to the needle assist device main seat 1.

[0160] As the needle storage box 6 moves downward, the distance between the needle storage box 6 and the needle assist device main seat 1 begins to decrease, and one end of the second elastic member 11 is connected to the lower surface of the first cross-section plate 81 of the columnar enclosure 8, and one end is connected to the bottom surface of the auxiliary member 83.

[0161] The motions of the first transmission ring 12, the second transmission ring 13 and the third transmission ring 14 become:

[0162] The first elastic member 10 drives the needle assist device main body 1 to move upward, that is, drives the side transmission part 2 to move upward. At this time, the third clamping protrusion 121 on the first transmission ring 12 is assembled in the groove 21, so it rotates with the shape of the groove 21. Since the fourth clamping protrusion 131 on the second transmission ring 13 cooperates with the clamping groove of the first transmission ring 12, and the clamping groove makes the fourth clamping protrusion 131 only rotate in a single direction, the first transmission ring 12 rotates together with the second transmission ring 13 and the third transmission ring 14, and the inner surface of the third transmission ring 14 is provided with a fifth clamping protrusion 141, and the fifth clamping protrusion 141 cooperates with the needle storage box 6. The second transmission ring 13 and the third transmission ring 14 move upward and rotate together under the push of the fifth clamping protrusion 141, and at the same time drive the needle storage box 6 to rotate.

[0163] The distance between the bottom surface of the needle storage box 6 and the bottom surface of the needle assisting device main body 1 is shortened.

[0164] The limiting ring 82 on the columnar enclosure 8 is separated from the auxiliary component 83, and there is a certain distance between them, and the distance begins to decrease.

[0165] At this time, the second elastic member 11 is compressed to the maximum value in step three, and starts to move in the opposite direction in this step, slowly rebounds, and moves upward, driving the needle aid main body 1 to move upward. The moving member 17 is set on the needle aid main body 1 and is driven upward by the limiting ring 82, thereby pushing open the second clamping protrusion 611, and the bottom end of the support member 20 is disengaged from the second clamping protrusion 611, and the distance between them gradually increases from zero, so that the needle storage box 6 continues to move upward.

[0166] At the same time, there is a needle withdrawal hook 601 on the needle storage box 6. During this step, the needle withdrawal hook 601 continues to engage with the annular groove 401. The injection needle body 4 is combined with the needle storage part 61 to fix the injection needle body 4. When the needle assisting device main body 1 moves upward, the injection needle body 4 is driven to continue to move upward.

[0167] The rotation angle is fixed and is set in the early stage of the manufacturing process.

[0168] It should be noted at this point that the injection needle body 4 must first be separated from the skin, and then rotate along with the needle storage box under the drive of the transmission ring 1, transmission ring 2, and transmission ring 3. At the same time, the groove 21 is provided with a certain travel distance in the vertical direction in order to cooperate with the completion of this action.

[0169] Step five, such as Figure 30-31 As shown, the state shown in the figure is that the needle insertion is completed, and the needle storage box 6 continues to rotate, wherein:

[0170] The remaining steps are Figure 24 The process is the same as step 4, except that the engagement between the annular groove 401 on the needle body 4 and the needle extraction hook 601 of the needle storage box 6 is released. During the rotation process, the hard needle portion at the lower end of the needle body 4 contacts the ejector seat 101 on the needle body 4 seat, and the rotation stops. At this point, the needle storage portion 61 is directly above the ejector seat 101.

[0171] In this step, the first engaging protrusion 211 is not engaged with the rib 160 of the main body shell 16 , and in this state, the first engaging protrusion 211 is located below the rib 160 .

[0172] Step six, such as Figures 32-34 As shown, a single trip is completed, and the status of the remaining components is the same as Figure 18 The state is the same, the difference is that there is a corresponding waste needle on the ejector seat 101. Figure 32 When in the status, there is no corresponding waste needle.

[0173] exist Figure 28 In the state shown, refer to Figure 29In this step, the annular groove 401 on the injection needle body 4 is engaged with the needle storage hook 612 of the needle storage box 6, so that the injection needle body 4 is fixed in the needle storage part 61 of the needle storage box 6.

[0174] Reference Figure 36 In this step, the first locking protrusion 211 is not combined with the rib 160 of the main body shell 16 , and in this state, the first locking protrusion 211 is located below the rib 160 .

[0175] Repeat the above process until the number of times is exhausted.
