Description

Technical Field

[0001] The utility model belongs to the technical field of insulin pens, in particular to an insulin pen. Background Art

[0002] Insulin pens save patients from the tedious process of using a syringe to extract insulin from an insulin bottle, and can save patients from the embarrassment of injecting insulin in public. Before each injection, check to make sure there is a sufficient dose of insulin, then rotate the dose adjustment knob to adjust to the required number of injection units. Before injection, one unit of insulin must be discharged to ensure that the insulin is injected into the body. The standard for successful exhaust is to see a drop of insulin discharged with the naked eye, which is a relatively small drop. It is not easy for people with poor eyesight or the elderly to see this drop. At the same time, for patients with poor eyesight, if they cannot see the dial clearly, they cannot accurately adjust the insulin injection dose.

[0003] In response to the above technical problems, patent CN202120603751.8 proposes a multifunctional insulin pen with a magnifying glass, including an insulin pen body, a transparent observation window at the tip end of the insulin pen body, a dial on the tail end side wall of the insulin pen body, a quick-release bracket tightly sleeved on the insulin pen body and a magnifying glass arranged on the quick-release bracket, the quick-release bracket is supported by an elastic material, a support frame for installing the magnifying glass is fixedly arranged on the quick-release bracket, and the plane where the support frame is located is parallel to the axial section of the quick-release bracket. The utility model can be installed and disassembled from the pen body quickly and conveniently by adding a magnifying glass to the elastic bracket. Through this device, patients with poor eyesight can observe the value of the dial well during the use of insulin, and the magnifying glass can also be installed at the pen tip to observe the discharge condition before injection.

[0004] However, the above solution is to use an external magnifying glass to magnify the content displayed in the observation window. The magnifying glass needs to be installed when in use, and needs to be stored when not in use, which may be easily lost. Therefore, further improvements can be made to make it more convenient to use. Utility Model Content

[0005] The utility model aims to provide an insulin pen, which adopts a convex lens arranged on the pen cover to magnify the display content of the dosage window on the pen shaft, does not need to install additional structures such as a magnifying glass, is easy to use, and is convenient for use by the elderly or people with poor eyesight.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an insulin pen, comprising a pen body and a pen cover mounted on the pen body, characterized in that a traction rope is detachably connected between the pen cover and the pen body, a dosage viewing window is embedded in the end of the pen body away from the pen cover, a convex lens arranged along the circumferential direction of the pen body is inserted into the pen cover, and a fixed cover is inserted into the end of the convex lens away from the pen cover.

[0007] Furthermore, a snap button is fixed on one end of the pen cover, a hanging ring is buckled inside the snap button, and one end of the traction rope is fixed inside the hanging ring.

[0008] Furthermore, a connecting seat is fixed on the side of the pen holder, and one end of the traction rope is fixed inside the connecting seat.

[0009] Furthermore, the cross section of the convex lens is T-shaped, and a semi-annular groove is provided on the pen body for inserting one end of the convex lens.

[0010] Furthermore, the fixing sleeve is provided with a clamping groove near the convex lens end, a rubber sleeve is fixedly bonded along the inner wall of the clamping groove, and a plurality of convex points are provided on the convex lens end facing the fixing sleeve.

[0011] The beneficial effects of the utility model are:

[0012] 1. A convex lens arranged on the pen cap is used to magnify the content displayed in the dosage window on the pen barrel, and no additional magnifying glass or other structures are required. It is easy to use and is convenient for the elderly or people with poor eyesight to use.

[0013] 2. A traction rope is set between the pen cap and the pen holder to prevent the pen cap from being lost. At the same time, the traction rope is connected between the connecting seat and the hanging ring, and the hanging ring and the snap button are detachable for easy selection and use.

[0014] 3. The convex lens can be easily replaced. The specific plug-in method makes it easy to replace the convex lens in time after it is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] Please also refer to Figures 1 to 4 The insulin pen of the utility model embodiment will be described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the insulin pen includes a pen body 1, a pen cover 2 mounted on the pen body 1, a traction rope 3 is detachably connected between the pen cover 2 and the pen body 1, a dosage viewing window 4 is embedded in the end of the pen body 1 away from the pen cover 2, a convex lens 5 arranged along the circumferential direction of the pen body 1 is inserted on the pen cover 2, and a fixing sleeve 6 is inserted into the end of the convex lens 5 away from the pen cover 2.

[0023] The convex lens 5 can be easily replaced, and a specific plug-in method is used, so that the convex lens 5 can be replaced in time after being damaged. The cross-section of the convex lens 5 is T-shaped, and a semi-annular groove 10 is provided on the pen shaft 1 for plugging one end of the convex lens 5. The other end of the convex lens 5 is plugged into the fixing sleeve 6. The fixing sleeve 6 is provided with a clamping groove 11 near the end of the convex lens 5, and a rubber sleeve 12 is fixedly bonded along the inner wall of the clamping groove 11. A plurality of convex points 13 are provided on the end of the convex lens 5 facing the fixing sleeve 6. A plurality of convex points 13 are provided on the contact surface between the convex lens 5 and the rubber sleeve 12, so as to increase the friction between the two and prevent the fixing sleeve 6 from slipping. When the convex lens 5 needs to be replaced, the fixing sleeve 6 can be pulled out for replacement.

[0024] The operating principle of this solution is as follows: the convex lens 5 has a magnifying function, so during use, the pen cover 2 is removed and put on the end of the pen shaft 1, that is, the end of the dosage visual window 4 set, and in this embodiment, the basic principle of the dosage visual window 4 is based on the existing insulin pen design, and the distance between the dosage visual window 4 and the end of the pen shaft 1 is equal to the distance from the convex lens 5 to one end of the fixed cover 6. Therefore, after the pen cover 2 is put into the end of the pen shaft 1, the position of the convex lens 5 corresponds to the position of the dosage visual window 4. Therefore, when observing the dosage visual window 4, its display content can be magnified, which is convenient for use by the elderly or people with poor eyesight.

[0025] In order to further avoid the pen cover 2 from being lost, a traction rope 3 is arranged between the pen cover 2 and the pen body 1 to prevent the pen cover 2 from being lost. Specifically, a snap button 7 is fixed at one end of the pen cover 2, and a hanging ring 8 is buckled inside the snap button 7. One end of the traction rope 3 is fixed inside the hanging ring 8. The snap button 7 adopts the existing mountaineering buckle structure. At the same time, a connecting seat 9 is fixed on the side of the pen body 1. One end of the traction rope 3 is fixed inside the connecting seat 9. The traction rope 3 is connected between the connecting seat 9 and the hanging ring 8. The hanging ring 8 and the snap button 7 are detachable for convenient selection and use.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
