DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-Figure 3 A self-service injection device for treating diabetic patients is shown, comprising: a syringe 1, a piston 3 is arranged inside the syringe 1, a bottom cylinder 4 is arranged at the bottom of the syringe 1, an injection assembly 5 is arranged on the top of the bottom cylinder 4, and a push rod 2 is arranged on the piston 3; the injection assembly 5 includes a receiving groove opened inside the bottom cylinder 4 and a connecting part 52 arranged inside the receiving groove, and an injection needle 51 is arranged at the bottom of the connecting part 52; a shunt assembly is arranged on the injection needle 51, and the shunt assembly includes a plurality of needle holes 53 opened on the injection needle 51; a fitting assembly is arranged on the top of the syringe 1, and the fitting assembly includes a push ring 8 arranged on the top of the syringe 1.

[0028] As can be seen from the above, when in use, the injection needle 51 is first inserted into the medicine bottle, and then the push rod 2 is pulled, so that the push rod 2 pulls the piston 3 in the syringe 1, thereby completing the extraction of the medicine in the medicine bottle. After the extraction is completed, the injection needle 51 is inserted into the patient's body, and then the push rod 2 is pushed, so that the piston 3 squeezes and pushes the medicine as the push rod 2 pushes, and the medicine is injected into the patient's body. The needle hole 53 facilitates the dissolution of the medicine, thereby increasing the fusion speed of the medicine and the patient, which is convenient for the patient to treat diabetes.

[0029] refer to Figure 1 , Figure 2 and Figure 4 As shown, the self-service injection device for treating diabetic patients also includes a protective component 6, which includes a protective tube 61 covering the injection component 5 and a sponge cushion 63 arranged at the bottom of the protective tube 61, and needle holes are opened on the sponge cushion 63 and the protective tube 61, and the injection component 5 is located in the needle hole; a connecting component is arranged between the bottom tube 4 and the protective tube 61, and the connecting component includes a connecting part 62 arranged on the protective tube 61, and the connecting part 62 is sleeved on the bottom tube 4.

[0030] Through the above technical solution:

[0031] When injecting a patient, the sponge cushion 63 first contacts the patient's skin, and then when the injection needle 51 penetrates into the patient's body, the sponge cushion 63 moves with the injection needle 51 to squeeze part of the patient's skin. When the squeezing force is too large, the connecting part 52 slides on the bottom tube 4 to reduce the pressure generated by the sponge cushion 63. Before the injection needle 51 is used, the protective tube 61 can effectively protect the injection needle 51 to prevent the injection needle 51 from bending and affecting subsequent use.

[0032] In addition, refer to Figure 1 , Figure 2 and Figure 5 As shown, a quantitative component 7 is provided on the push rod 2, and the quantitative component 7 includes a bonding plate 71 arranged on the push rod 2 and a mounting plate 72 arranged on one side of the bonding plate 71, and a scale line 73 is provided on the mounting plate 72; a connecting component is provided between the mounting plate 72 and the bonding plate 71, and the connecting component includes a plug-in slot opened on the bonding plate 71 and a plug-in block 74 arranged on the mounting plate 72, and the plug-in block 74 is in the plug-in slot.

[0033] Through the above technical solution:

[0034] When in use, first align the plug-in block 74 with the plug-in slot, then press the mounting plate 72 to complete the installation of the mounting plate 72 with the fitting plate 71, and then when the injection needle 51 extracts the medicine, the fitting plate 71 is pulled by the push rod 2 to move the fitting plate 71 and the mounting plate 72, and then the scale line 73 and the push ring 8 are observed to facilitate the detection of the amount of medicine inside the syringe 1. When the appropriate medicine is reached, the extraction is stopped, and then the patient is directly injected to avoid excessive injection of medicine that affects the patient's subsequent treatment.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
