[0002] Insulin is a protein drug that is extremely sensitive to temperature and has strict storage requirements. The traditional storage method is refrigeration, and the temperature is usually set at 2-8°C. However, this storage method is not suitable for diabetic users who need to travel for short periods of time. Carrying traditional refrigeration equipment such as refrigerators or ice packs is cumbersome and inconvenient. Moreover, in outdoor environments, insulin pens or medicine bottles are often exposed to high or low temperatures, causing insulin to denature and become ineffective, affecting the treatment effect.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-11, a convenient insulin storage and injection device comprises an insulation box 1, characterized in that an insulation upper cover 2 is rotatably provided on the upper surface of the insulation box 1, a tube pusher rack 3 and an insulin tube 4 are vertically placed in the insulation box 1, an insulin tube pusher rod 5 is vertically movably provided in the inner cavity of the tube pusher rack 3, a limiting mechanism 6 is installed on the side wall on one side of the bottom of the tube pusher rack 3, a pusher rod sliding rack 32 is arranged at the bottom of the inner wall of the tube pusher rack 3, the insulin pusher rod 5 is vertically slidably fitted on the pusher rod sliding rack 32, slots 31 are symmetrically provided on the side walls on both sides of the bottom of the tube pusher rack 3, the insulin tube is installed at the slots 31, a grip portion 33 is provided on the side wall on one side of the tube pusher rack 3, a limiting block 34 for clamping the insulin pusher tube 5 is arranged on the inner wall of the cavity at the top of the tube pusher rack 3, and the tube pusher rack 3 is smaller in size than a traditional insulin pen.

[0031] Among them, a hanging ring 11 is arranged on the top of the side wall of one side of the thermal insulation box 1, a tube pusher rack placement groove 14 is opened on the upper surface of the thermal insulation box 1, an insulin placement groove 15 is opened on one side of the tube pusher rack placement groove 14, a groove 13 is opened on the upper surface of the thermal insulation box 1 between the tube pusher rack placement groove 14 and the insulin placement groove 15, a magnetic suction groove 12 is opened on the other side of the tube pusher rack placement groove 14 away from the groove 13 on the upper surface of the thermal insulation box 1, a tube pusher rack 3 is vertically placed in the tube pusher rack placement groove 14, and an insulin tube 4 is vertically placed in the insulin placement groove 15, so that the thermal insulation box 1 is effectively isolated from external high or low temperatures.

[0032] In addition, a magnetic gasket 21 is provided at the bottom surface of the thermal insulation upper cover 2 , and the magnetic gasket 21 is magnetically engaged in the magnetic groove 12 , so that the thermal insulation upper cover 2 can be covered on the thermal insulation box 1 .

[0033] Moreover, an insulin chamber 42 is provided inside the insulin tube 4, and an air plug 8 is vertically movably provided in the insulin chamber 42. Limiting convex plates 41 are symmetrically provided on the outer walls on both sides of the top of the insulin tube 4, and the limiting convex plates 41 are used to be installed in the slot 31. An assembly head 43 is provided at the bottom of the insulin tube 4, and the assembly head 43 is used to connect to the existing disposable needle 7.

[0034] In addition, a chassis mounting groove 81 is provided on the upper surface of the air plug 8, and the bottom of the insulin tube push rod 5 is connected to the chassis mounting groove 81. The air plug 8 is used to push out the insulin liquid.

[0035] At the same time, a connecting chassis 51 is provided at the bottom of the insulin tube push rod 5, and rubber blocks 52 are symmetrically provided on the upper surface of the connecting chassis 51. The connecting chassis 51 is rotated and clamped in the connecting chassis mounting groove 81. A pressing plate 53 is provided on the top of the insulin tube push rod 5. A reinforcing block 54 is fixedly connected between the pressing plate 53 and the insulin tube push rod 5. The pressing plate 53 and the reinforcing block 54 are clamped at the limit clamping block 34. The reinforcing block 54 is used to improve the firmness of the pressing plate 53.

[0036] Among them, the limiting mechanism 6 includes a limiting plate 61, and sliding frames 62 are movably arranged on both sides of the limiting plate 61. The sliding frames 62 are symmetrically installed on the side walls of the tube pushing rack 3. The limiting plate 61 is used to block one side of the slot 31. A pushing plate 611 is arranged in the middle of the limiting plate 61. Slide blocks 612 are symmetrically fixedly connected on both sides of the limiting plate 61. The slide blocks 612 are slidably fitted on the sliding frames 62. A baffle 613 is symmetrically fixedly connected to the bottom of the limiting plate 61. The baffle 613 is located on one side of the slot 31 and is used to block the insulin tube 4.

[0037] In addition, a sliding rod 621 is provided on the sliding frame 62, and the slider 612 is slidably fitted on the sliding rod 621. A spring 9 is sleeved on the sliding rod 621. One end of the spring 9 is fixedly connected to the sliding frame 62, and the other end is fixedly connected to the top of the slider 612. The spring 9 facilitates the resetting of the limit plate 61.

[0038] In this embodiment, when the user is traveling for a short period of time, the insulin tube 4 containing insulin and the tube pusher 3 can be taken out of the refrigerator and placed in the thermal insulation box 1, and they can be inserted into the tube pusher placement slot 14 and the insulin tube placement slot 15 respectively, and then the thermal insulation cover 2 can be buckled on the thermal insulation box 1, and the thermal insulation box 1 can be put in a bag to carry out, because the thermal insulation box 1 has a better volume than the traditional insulin thermal insulation box and is more convenient to carry.

[0039] During temporary use, the tube pusher rack 3 and the insulin tube 4 are taken out through the groove 13, and the tube pusher rack 3 and the insulin tube 4 are assembled. First, the push plate 611 is swung to drive the sliders 612 on both sides to move upward at the slide rod 621, and the spring 9 is contracted so that the baffle 613 no longer blocks the slot 31. At this time, the insulin tube 4 can be inserted, and then the push plate 611 is released. The spring 9 releases its elastic potential energy, driving the slider 612 to reset, so that the baffle 613 is blocked at the slot 31 again.

[0040] At this time, adjust the insulin tube push rod 5, rotate it out from the limit block 34, and then insert its connecting chassis 51 into the connecting chassis mounting groove 81 of the air plug 8, and rotate the insulin tube push rod 5 so that the connecting chassis 51 is stuck in the Nanjing chassis mounting groove 81, and the rubber block 52 increases its damping to prevent it from being easily rotated out. At this time, the user slowly pushes the insulin tube push rod 5, so that the insulin is discharged from the disposable needle 7, and then the injection can be started. When the insulin liquid in the insulin tube 4 is used up, the insulin tube push rod 5 can be pulled back, and a new disposable needle 7 can be replaced to draw insulin into the insulin chamber 42.

[0041] In the present invention, the tube pusher rack 3 and the insulin tube 4 are smaller in size and are of a split assembly type. When carrying, they can be placed separately in a small insulation box 1 and assembled again when in use. The tube pusher rack 3 can also retract the air plug 8 so that insulin can be re-extracted. Such an insulin guarantee and injection device is small in size, easy to carry, and is convenient for users to carry for a short period of time.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
