Description

Technical Field

[0001] The utility model relates to the technical field of syringes, in particular to an insulin pen with voice prompt and a tail device. Background Art

[0002] An insulin pen is a tool for insulin injection, which is used for injecting insulin during the treatment of diabetic patients. The insulin pen eliminates the cumbersome process of diabetic patients extracting insulin from an insulin vial with a syringe, making the insulin injection process simpler and more concealed, and eliminating the embarrassment of diabetic patients injecting insulin in public.

[0003] Currently, the insulin pens provided by mainstream insulin companies are mainly divided into two types. One is an integrated type, which needs to be discarded as a whole after use and cannot be reused, with a lower cost; the other is a split type, that is, the pen refill can be replaced, enabling the insulin pen to be reused, with a higher cost.

[0004] In existing patent documents, to take care of patients with poor eyesight, various insulin pens with voice broadcast dosage and electronic display dosage are proposed. However, if this function is applied to an integrated insulin pen, the use cost will increase significantly.

[0005] Patent document CN220142329U discloses an insulin pen. On the basis of a conventional reusable insulin pen, this insulin pen adds a prompt component. By sensing the extended length of the injection push key, the injection scale value of the dosage display window can be detected. Further, the measured injection amount is reminded to the patient in the form of voice broadcast through a sound playback component, which is beneficial for patients with poor eyesight to use and reduces the possibility of injecting an insulin dosage that does not meet the requirements due to misreading the injection amount.

[0006] Patent document CN221154962U discloses an insulin pen with audible and visible dosage. By rotating the adjustment knob, the pin inserted into the encoder is driven to rotate at the same time. Through the cooperation of the control module, the rotation value is calculated and displayed on the display screen. At the same time, voice prompt is carried out through the voice module to achieve double insurance, which is convenient for patients to manually adjust and improves the accuracy of the injection dosage; the pen clip carries a needle, further improving the use performance of the insulin pen.

[0007] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the present utility model, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and creativity of this application.

[0023] Figure 2 is a front view of the tail device of the present utility model. Detailed Embodiments

[0024] The present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present utility model.

[0025] Referring to the following drawings, non-limiting and non-exclusive embodiments will be described, in which like reference numerals represent like components, unless otherwise specifically stated.

[0026] As Figures 1-2 shown, a tail device of an insulin pen with voice prompt includes an outer bracket 4, a sliding bracket 2, and a voice prompt device. Among them, the outer bracket 4 includes a circular cylinder body with upper and lower openings. The sliding bracket 2 is slidably installed inside the cylinder body, and its upper part extends from the upper end face of the cylinder body. The sliding bracket has an H-shaped structure, forming a lower assembly space 23 on the lower side and an upper assembly space 21 on the upper side. The voice prompt device is installed in the upper assembly space 21. At least two adjusting screws 5 are arranged horizontally on the side of the lower assembly space 23. In this embodiment, the sliding bracket 2 and the outer bracket 4 are in clearance fit. The sliding bracket 2 can not only rotate circumferentially inside the outer bracket 4 but also slide up and down relative to the outer bracket 4. During use, the lower part of the outer bracket 4 is connected and fixed to the upper part of the insulin pen for positioning, so that the injection push key 6 of the insulin pen extends into the lower assembly space 23, and then the adjusting screw 5 is tightened to clamp the injection push key 6. In this way, by rotating the sliding bracket part extending from the upper end face of the cylinder body, the injection push key 6 can be driven to rotate, thereby adjusting the injection dose.

[0027] For an integrated insulin pen, the injection dose is generally adjusted by rotating the injection push button 6. Among them, when the injection push button 6 is rotated clockwise, the injection dose is increased. And as the dose increases, the end face of the injection push button 6 gradually moves away from the insulin pen end; when the dose adjustment is in place and it is time to inject, press the end face of the injection push button 6 with hand, so that the end face of the injection push button 6 gradually moves towards the insulin end and resets, and the medicine is injected into the patient's body. In this embodiment, the lower part of the sliding bracket 2 clamps the injection push button 6, so that the injection push button 6 and the sliding bracket 2 rotate or move up and down synchronously. In this way, the patient operates the upper mechanism of the sliding bracket 2 to complete the operations of adjusting the injection dose and injecting.

[0028] In a preferred embodiment, after the adjusting screw 5 is installed in place, the height of the adjusting screw 5 protruding from the sliding bracket 2 is minimized as much as possible, or the head of the adjusting screw is sunk into the screw hole formed in the lower part of the sliding bracket 2 for connecting the adjusting screw 5, so as to avoid or reduce the interference of the adjusting screw 5 with the movement of the sliding bracket 2. Therefore, it is a better choice to use a countersunk head screw or a machine screw as the adjusting screw 5. More preferably, there are 2 adjusting screws 5, and the 2 adjusting screws 5 are arranged oppositely; or there are 3 adjusting screws 5, and the 3 adjusting screws 5 are evenly distributed in a circle at the lower part of the sliding bracket 2.

[0029] In some embodiments, when the sliding bracket 2 slides relative to the outer bracket 4, although it is possible to avoid interfering with the movement of the sliding bracket 2 by controlling the length of the adjusting screw 5, the sizes of the injection push buttons 6 of different insulin pens are different. Therefore, controlling the length of the adjusting screw 5 is not a very good choice. In this embodiment, by designing an anti-interference structure, there is a certain-width gap between the lower part of the sliding bracket 2 and the lower part of the outer bracket 4, providing sufficient space for the adjusting screw 5 to adapt to different injection push buttons 6.

[0030] For example, the anti-interference structure is that a convex ring 22 is provided on the outer side of the middle part of the sliding bracket 2, and the sliding bracket 2 is in clearance fit with the inner side of the outer bracket 4 through the outer side of the convex ring 22, that is, the sliding bracket 2 slides on the inner side of the outer bracket 4 through the convex ring 22. In this way, by providing the convex ring 22, there is a certain distance between the outer side of the convex ring 22 and the outer side of the sliding bracket 2, so as to separate the lower part of the sliding bracket 2 and the lower part of the outer bracket 4 by a corresponding distance. Preferably, a closing structure 41 is provided at the upper end of the outer bracket 4 to limit the sliding position of the sliding bracket 2.

[0031] Alternatively, the lower part of the outer bracket 4 is made into a flared structure, that is, the inner part of the outer bracket 4 is made into a stepped hole structure. Using the flared structure as the anti-interference structure can effectively avoid the interference between the sliding bracket 2 and the outer bracket 4.

[0032] Preferably, in the above solution, a weight-reducing window is provided at the lower part of the outer bracket 4 corresponding to the installation position of the adjusting screw 5. On the one hand, the weight is reduced while ensuring the structural strength of the outer bracket, and on the other hand, it is also convenient to operate the adjusting screw.

[0033] In a preferred embodiment, it further includes a compression cap 1, and the compression cap 1 is threadedly connected to the upper end of the sliding bracket 2.

[0034] In some other embodiments, an elastic clamp 7 with a closed end shape is provided at the lower end of the outer bracket 4. During use, the upper part of the insulin pen is clamped by the elastic clamp 7, so that the outer bracket 4 and the insulin pen are relatively fixed, preventing the outer bracket 4 from rotating when the sliding bracket 2 is rotated. Preferably, a magnifying glass is further installed at the lower part of the outer bracket 4. When installing the outer bracket 4, the magnifying glass is aligned with the dose display window of the insulin pen to magnify the dose value for easy viewing.

[0035] In some embodiments, the voice prompt device includes a control module, a voice module, a power supply module and a reading module, and the control module is signal-connected to the voice module, the power supply module and the reading module. Among them, the reading module includes an encoder 3, and the encoder 3 is installed in the upper assembly space 21, and its input end is fixedly connected to the sliding bracket 2 through a pin shaft 8. When the sliding bracket 2 rotates, the pin shaft 8 and the injection push key 6 are driven to rotate at the same time, and then the control module calculates the rotation value into the injection dose and broadcasts it through the voice module. In this way, when the patient adjusts the dose, the patient can determine the dose by listening to the voice broadcast or by observing through the magnifying glass.

[0036] In still some other embodiments, when the injection is completed and the injection push key 6 returns to the in-place position, the voice module broadcasts a countdown of 10 numbers. Generally, 10 seconds after injection, the insulin needle is pulled out to ensure the effectiveness of the injection.

[0037] An insulin pen includes the tail device of the insulin pen with the above-mentioned voice prompt.
