Description

Technical Field

[0001] This utility model relates to the field of insulin pen needles, specifically a comfortable large-flat insulin pen needle. Background Technology

[0002] An insulin pen needle is an injection tool designed specifically for diabetic patients. It is used in conjunction with an insulin pen to inject insulin subcutaneously to control blood sugar levels. The insulin pen needle is part of an insulin injection system and is usually used in conjunction with an insulin pen. An insulin pen is an injection device with a pre-filled or replaceable cartridge. It looks like a pen and is easy to carry and operate.

[0003] In existing technologies, insulin pens require the insulin needle to be connected to the pen body before insulin can be injected via the injection button. Typically, the insulin needle is housed inside the outer cap, connecting the needle to the pen. Currently, only one side of the outer cap contacts the body for needle control. However, this small area of ​​the outer cap makes the needle prone to slight shaking or wobbling during injection, increasing pain during use. Utility Model Content

[0004] To overcome the shortcomings of existing technology, the area of ​​one side of the outer needle cap is usually small. This makes it easy for the pen needle to wobble or shake slightly when injecting insulin when it is inserted into the body, due to the small size of the outer needle cap. This increases the pain and other problems that people experience when using the pen needle. This invention proposes a comfortable large-flat insulin pen needle.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a comfortable large-plane insulin pen needle, including an outer needle cap, the inner cavity of which is fixedly connected to the pen needle body, and an expansion mechanism is provided on the top of the outer needle cap;

[0006] The extension mechanism includes a fixed rod, one end of which is fixedly connected to the top of the outer needle cap. A fixed ring block is fixedly connected to the top of the fixed rod. A rotating ring block is rotatably connected to the surface of the fixed ring block. An installation rod is fixedly connected to the top of the fixed ring block. A connecting rod is fixedly connected to the top of the rotating ring block. A rotating plate is rotatably connected to the surface of the connecting rod. A rotating rod is rotatably connected to the inner cavity of the rotating plate. An extension block is rotatably connected to the surface of the rotating rod. The inner cavity of the extension block is rotatably connected to the surface of the installation rod.

[0007] Preferably, a first spring sheet is fixedly connected to the inner cavity of the rotating ring block, and a second spring sheet is fixedly connected to the inner cavity of the fixed ring block. A plurality of the first spring sheet and the second spring sheet are provided, and the plurality of the first spring sheet and the plurality of the second spring sheet are arranged alternately.

[0008] Preferably, a slider is fixedly connected to the inner cavity of the rotating ring block, and a groove is formed on the surface of the fixed ring block, with the surface of the slider slidably connected to the inner cavity of the groove.

[0009] Preferably, a reinforcing ring block is fixedly connected to the top of the outer needle cap, and the inner cavity of the reinforcing ring block is fixedly connected to the surface of the fixing rod.

[0010] Preferably, a mounting plate is fixedly connected to the surface of the outer needle cap, and a protective sleeve is movably adhered to the surface of the mounting plate.

[0011] Preferably, a slider is fixedly connected to the top of the outer needle cap, and the top of the slider is fixedly connected to the bottom of the fixing ring block.

[0012] Preferably, a rubber protective layer is movably bonded to the top of the extension block, and a rubber sealing layer is movably bonded to the bottom of the outer needle cap.

[0013] The advantages of this utility model are:

[0014] This invention utilizes the rotation of a rotating ring block, allowing it to smoothly pull the extension block via a rotating plate and a rotating rod. This enables the extension block to rotate and move smoothly around the center of the mounting rod, away from the center of the fixed ring block. After rotating a certain distance, the extension block, through contact with the skin, increases the stability of the pen needle during use. This prevents significant shaking or wobbling of the pen needle during insulin injection, reducing pain caused by instability and increasing comfort. It also addresses the problem of the small area of ​​the outer needle cap, which can cause slight shaking or wobbling during insulin injection, increasing pain. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0027] This application discloses a comfortable, large-flat insulin pen needle. (See also...) Figure 1 and Figure 8A comfortable large-flat insulin pen needle includes an outer needle cap 1, the inner cavity of which is fixedly connected to the pen needle body 2, and an extension mechanism 3 is provided on the top of the outer needle cap 1;

[0028] The extension mechanism 3 includes a fixed rod 301, one end of which is fixedly connected to the top of the outer needle cap 1. A fixed ring block 302 is fixedly connected to the top of the fixed rod 301. A rotating ring block 303 is rotatably connected to the surface of the fixed ring block 302. An installation rod 306 is fixedly connected to the top of the fixed ring block 302. A connecting rod 304 is fixedly connected to the top of the rotating ring block 303. A rotating plate 308 is rotatably connected to the surface of the connecting rod 304. A rotating rod 305 is rotatably connected to the inner cavity of the rotating plate 308. An extension block 307 is rotatably connected to the surface of the rotating rod 305. The inner cavity of the extension block 307 is rotatably connected to the surface of the installation rod 306.

[0029] The outer needle cap 1 enables the installation and fixation of the pen needle body 2. The pen needle body 2 allows for smooth insulin injection when the insulin pen is connected to the outer needle cap 1. The use of the outer needle cap 1, pen needle body 2, and insulin pen is prior art in this field and will not be elaborated upon here. The fixing rod 301 enables the installation and fixation of the fixing ring block 302. The fixing ring block 302, while connecting to the rotating ring block 303, also enables the installation of the mounting rod 306. The ring block 303 can be connected to the rotating plate 308 via the connecting rod 304. The rotating rod 305 connected inside the rotating plate 308 can cooperate with the mounting rod 306 to connect the extension block 307. This allows the rotating ring block 303 to rotate and move smoothly via the connecting rod 304 when it rotates, thereby pulling and rotating the extension block 307 and enabling the extension block 307 to rotate and move away from the center of the fixed ring block 302.

[0030] Reference Figure 6 The inner cavity of the rotating ring block 303 is fixedly connected to a first spring piece 11, and the inner cavity of the fixed ring block 302 is fixedly connected to a second spring piece 12. Several first spring pieces 11 and several second spring pieces 12 are provided. The arrangement of the second spring pieces 12 and the first spring pieces 11 allows the rotating ring block 303 to rotate smoothly through the elasticity of the second spring pieces 12 and the first spring pieces 11 when it needs to be rotated. When the rotating ring block 303 does not need to rotate, the reverse rotation of the rotating ring block 303 can be restricted by the alternating arrangement of the first spring pieces 11 and the second spring pieces 12, thereby achieving the limitation of the rotating ring block 303 when it is not rotating.

[0031] Reference Figure 4 and Figure 7A slider 9 is fixedly connected to the inner cavity of the rotating ring block 303. A groove 10 is provided on the surface of the fixed ring block 302. The surface of the slider 9 is slidably connected to the inner cavity of the groove 10. The groove 10 and the slider 9 can effectively limit the rotational connection between the fixed ring block 302 and the rotating ring block 303, making the connection between the fixed ring block 302 and the rotating ring block 303 stable enough and preventing it from falling off. It also increases the stability of the rotating ring block 303 when rotating.

[0032] Reference Figure 3 and Figure 4 A reinforcing ring 6 is fixedly connected to the top of the outer needle cap 1. The inner cavity of the reinforcing ring 6 is fixedly connected to the surface of the fixing rod 301. The reinforcing ring 6 can reinforce the connection between the outer needle cap 1 and the fixing rod 301 through its connection with the outer needle cap 1 and the fixing rod 301, so that when the fixing rod 301 is used on the top of the outer needle cap 1, it is not easy for the bottom of the fixing rod 301 to break with the outer needle cap 1.

[0033] Reference Figure 1 and Figure 3 An mounting plate 7 is fixedly connected to the surface of the outer needle cap 1, and a protective sleeve 8 is movably bonded to the surface of the mounting plate 7. The mounting plate 7 enables the connection of the protective sleeve 8, which in turn can shield and protect the pen needle body 2 under normal circumstances or when the pen needle body 2 is not in use, thereby effectively reducing the possibility of damage to the pen needle body 2 when it is not in use.

[0034] Reference Figure 2 The top of the outer needle cap 1 is fixedly connected to a slider 9. The top of the slider 9 is fixedly connected to the bottom of the fixing ring block 302. The slider 9 can further reinforce and support the use of the fixing ring block 302, so that the fixing ring block 302 can be stable enough during use and is not easy to shake or tilt.

[0035] Reference Figure 2 and Figure 3 The top of the extension block 307 is movably bonded with a rubber protective layer 4, and the bottom of the outer needle cap 1 is movably bonded with a rubber sealing layer 5. The rubber protective layer 4 prevents discomfort caused by the coldness of the extension block 307 when it comes into contact with the body, especially in cold weather. The rubber sealing layer 5 provides a seal between the outer needle cap 1 and the insulin pen, increasing the sealing performance and stability of the outer needle cap 1 during use.

[0036] Working Principle: When using this device, the operator can remove the protective cover 8 from the top of the mounting plate 7, and then connect the outer needle cap 1 to the top of the insulin pen. At this time, the pen needle body 2 can be smoothly inserted into the insulin pen, enabling normal insulin injection. Afterwards, the operator can rotate the rotating ring block 303. When the rotating ring block 303 rotates, it smoothly drives the rotating plate 308 to rotate and move via the connecting rod 304. Through the rotation and movement of the rotating plate 308, and the connection between the rotating rod 305 and the expansion block 307, the expansion block 307 is pulled, causing the expansion block 307 to move. 7 can smoothly rotate and move around the center of the mounting rod 306, and move and rotate to the side away from the center of the fixed ring block 302. When the extension block 307 moves a certain distance away from the center of the fixed ring block 302, people can use the pen needle body 2 and insulin pen normally. When the pen needle body 2 is inserted into the body, the extension block 307 can contact the skin. Through the contact between the extension block 307 and the body, the stability of the pen needle body 2 and insulin pen during use is increased, thereby reducing the shaking and vibration of the pen needle body 2 during use.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
