Description

Technical Field

[0001] This utility model relates to insulin injection aids, specifically to an automatic insulin pen needle extractor. Background Technology

[0002] An insulin pen is an injectable medical device used to administer insulin to patients, and it is widely used among diabetic patients. In terms of physical structure, an insulin pen consists of a pen body and a needle. The needle is detachably attached to the lower end of the pen body using a threaded connection. The needle of an insulin pen differs from that of a conventional syringe needle; its overall structure is very small, especially the metal needle at the tip, which is only 3-5 mm long, often resulting in hand pricking when inserting or removing the needle.

[0003] Regarding the problem of needle pricks, there are already some solutions in the existing technology, such as the corresponding content described in the following patent documents.

[0004] 1. Chinese utility model patent CN205796174U describes a safety needle for an insulin pen. The needle is installed inside a protective sleeve at the front end of the pen using a compression spring. During injection, under pressure, the protective sleeve gradually retracts relative to the needle body due to the compression spring, allowing the injection section of the needle to gradually extend from the needle eye in the protective sleeve and pierce the patient's body for insulin injection. After injection, the injection section of the needle is withdrawn from the patient's body, and the protective sleeve returns to its original position under the action of the spring, with the injection section completely retracting into the protective sleeve. In other words, during non-injection periods, the injection section of the needle remains within the cavity of the protective sleeve, with the needle not exposed, thus preventing needle pricks.

[0005] 2. Chinese utility model patent CN217138867U describes an insulin pen anti-needle cap holder. By setting up a needle cap holder body, before use, the needle cap holder body is fixed on a table with a certain magnetic force. The magnet block set at the bottom of the needle cap holder body can be attracted to the table to generate a certain attraction force to fix the needle cap holder body. After fixing the needle cap holder body, when it is necessary to remove the needle, simply insert the needle cap into the receiving groove, then insert the insulin pen needle into the needle cap, and rotate the insulin pen in the opposite direction until the needle and the needle cap are threadedly connected, thereby preventing the needle from being accidentally inserted into the finger.

[0006] 3. Chinese invention patent document with publication number CN114404738A describes a portable insulin pen needle extractor, which involves core components such as a connecting cylinder, a threaded sleeve, a needle holder, a push rod, a push block, and a push block limiting ring. When using it, hold the needle extractor, align it with the needle of the insulin pen, align the protrusion inside the needle holder with the groove on the outer surface of the needle, and then rotate the insulin pen or the device to install or remove the needle. For the removed needle, press the pressing cylinder directly, and push the push block downward through the push rod to push the needle out of the needle holder. Then the spring force pushes the push rod to return to its original position.

[0007] Existing technological solutions mainly focus on two aspects: improving the needle itself and adding a separate needle removal device. Improving the needle itself increases the cost of insulin pen use, placing a significant financial burden on patients. Current needle removal devices are at best handheld clamping mechanisms, requiring users to actively clamp the needle and twist it with both hands to remove the threads; their convenience needs further improvement. Utility Model Content

[0008] In view of this, the present invention provides an automatic needle remover for insulin pens, which aims to complete the automatic removal of needles in a simpler way, thereby avoiding hand pricking.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows:

[0010] An automatic insulin pen needle retriever, the key features of which include: a waste needle storage box with a needle retrieval opening at its upper end; a rotating seat rotatably mounted within the waste needle storage box, on which two sets of clamping components are symmetrically mounted, each clamping component having a shaft rotatably connected to the rotating seat and a pressure plate and a clamping piece extending outward from the side of the shaft, the pressure plate and the clamping piece having an included angle, wherein the pressure plate is located above the rotating seat, and each of the two sets of clamping components is provided with an elastic element between it and the rotating seat, the two sets of clamping components being located at the needle retrieval opening, under the action of the elastic element, the clamping pieces of the two sets of clamping components tilt outward relative to the height direction of the rotating seat and open, after the insulin needle tip is pressed down onto the pressure plate of the two sets of clamping components, the clamping pieces can be forced to rotate inward to clamp the needle tip; and a driving assembly for driving the rotating seat to rotate.

[0011] Preferably, the drive assembly includes a motor base fixed inside the waste needle storage box, a motor is fixedly installed inside the motor base, and the lower end of the rotating seat is fixedly sleeved on the output shaft of the motor.

[0012] Preferably, the elastic element is a compression spring, with its lower end connected to the top of the rotating seat and its upper end connected to the lower side of the pressure plate.

[0013] Preferably, a pressure sensor is provided between the lower side of the pressure plate and the rotating seat, and the pressure sensor is associated with the control switch of the motor.

[0014] Preferably, the rotating base is a cylinder with a notch on one side of the upper part and a support platform on the other side. The two sets of clamping components are rotatably mounted on both ends of the support platform. The clamping piece is an arc-shaped piece, and when clamping the needle, the center line of the arc-shaped piece coincides with the center line of the rotating base.

[0015] Preferably, the lower side of the notch has an inclined surface. A cover is provided on one side of the waste needle storage box.

[0016] Preferably, the motor base is an annular housing with a central mounting hole and an annular cavity surrounding the central mounting hole. The motor is vertically fixed inside the central mounting hole, and a battery and a motor controller are installed inside the annular cavity.

[0017] This utility model also provides a sharps container, which has the above-mentioned automatic insulin pen needle dispenser, and the container body constitutes the waste needle storage box.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Using the automatic insulin pen needle retrieval device provided by this utility model, the lower end of the insulin pen carrying the needle is inserted into the needle retrieval opening, and the needle seat is pressed against the pressure plates of the two sets of clamping components. Pressing down forcefully causes the two sets of clamping components to rotate inward until the two sets of clamping plates at both ends clamp the needle seat. Then, the drive assembly drives the rotating seat to rotate, thus unscrewing the needle from the lower end of the insulin pen, achieving automatic needle retrieval. After needle retrieval, the needle automatically falls into the waste needle storage box. Subsequently, under the pushing force of the elastic element, the clamping components return to a slightly outward tilted opening for the next use.

[0020] 2. The automatic insulin pen needle extractor provided by this utility model uses a clamping component that is linked to the motor control switch via a pressure sensor. This ensures that once the needle is clamped in place, the motor can automatically loosen it, which has the technical advantage of high ease of use.

[0021] 3. As a storage device for medical sharps waste, the sharps box integrates an automatic needle extractor. It not only has the advantages of convenient use and management and secure needle extraction, but also has broad market application prospects. Attached Figure Description

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0030] Example 1

[0031] like Figure 1 As shown, an automatic insulin pen needle dispenser includes a waste needle collection box 1 for collecting needles, with a needle dispensing opening 1a at the top. (This is in conjunction with the attached...) Figure 2 and 3 As can be seen, the waste needle storage box 1 is equipped with a rotating base 2, two sets of clamping components 3, and a drive assembly 5 that drives the rotating base 2 to rotate. After the two sets of clamping components 3 clamp the needle, the drive assembly 5 drives the rotating base 2 to rotate, thereby removing the needle from the end of the insulin pen.

[0032] Furthermore, the specific installation relationship of the rotating base 2, the two sets of clamping components 3, and the drive assembly 5 inside the waste needle storage box 1 is as follows:

[0033] Please refer to the attached document. Figure 2 The rotating base 2 is rotatably installed inside the waste needle storage box 1. Two sets of clamping components 3 are rotatably and symmetrically arranged on the upper end of the rotating base 2, and then combined with the attached... Figure 3It can be seen that the clamping component 3 has a shaft 3a rotatably connected to the rotating seat 2, and a pressure plate 3b and a clamping piece 3c extending outward from the side of the shaft 3a. The pressure plate 3b and the clamping piece 3c have an included angle of 90° with each other. After the clamping component 3 is rotatably connected to the rotating seat 2 via the shaft 3a, the pressure plate 3b is in an inward extending state and located above the rotating seat 2, and the clamping piece 3c is in an upward extending state. An elastic element 4 is provided between both sets of clamping components 3 and the rotating seat 2. The two sets of clamping components 3 are located at the needle extraction opening 1a. Under the action of the elastic element 4, the clamping pieces 3c of the two sets of clamping components 3 are slightly tilted outward relative to the height direction of the rotating seat 2 and open, forming an open state directly facing the needle extraction opening 1a.

[0034] Based on the above design, please refer to the attached document. Figure 4 and Figure 5 Insert the lower end of the insulin pen 7, which carries the needle 8, into the needle retrieval opening 1a, and press the needle seat 8a of the needle 8 onto the pressure plates 3b of the two sets of clamping components 3. Pressing down forcefully will cause the two sets of clamping components 3 to rotate inward until the two sets of clamping plates 3c at both ends clamp the needle seat 8a. Then, the drive assembly 5 drives the rotating seat 2 to rotate, which will unscrew the needle 8 from the lower end of the insulin pen 7, realizing automatic needle retrieval. After the needle is retrieved, the needle 8 automatically falls into the waste needle storage box 1. Then, under the pushing force of the elastic element 4, the clamping components 3 return to a slightly outward tilted opening for the next use.

[0035] In this embodiment, please refer to the attached document. Figure 3 As shown, the rotating base 2 is cylindrical in shape, with a notch 2a on one side of the upper part of the cylinder and a support platform 2b on the other side. Two sets of clamping components 3 are rotatably mounted on both ends of the support platform 2b. In use, the lower side of one end of the needle holder 8a of the needle 8 presses against the pressure plate 3b of the clamping component 3, forming a seesaw structure. After the needle 8 is unscrewed from the lower end of the insulin pen 7, it can automatically fall into the waste needle storage box 1 under the action of gravity. The clamping plate 3c is designed as an arc-shaped plate. When clamping the needle 8, the center line of the arc-shaped plate coincides with the center line of the rotating base 2. This ensures that when the drive component 5 drives the rotating base 2 to rotate, the needle 8 rotates concentrically, satisfying the feasibility of loosening in the design.

[0036] like Figure 6 As shown, in the two sets of clamping components 3 mounting structure, the end of the clamping piece 3c near the notch 2a extends above the notch 2a, and when clamping the needle 8, the end of the clamping piece 3c near the notch 2a exceeds half of the needle seat 8a, so as to ensure that the two sets of clamping components 3 stably clamp the needle 8.

[0037] For example Figure 2As shown, in this embodiment, the driving assembly 5 includes a motor base 5a fixed inside the waste needle storage box 1. The motor base 5a is an annular shell with a vertically arranged central mounting hole 5a1 and an annular cavity 5a2 located around the central mounting hole 5a1. A motor 5b is vertically fixed inside the central mounting hole 5a1, and the lower end of the rotating seat 2 is fixedly sleeved on the output shaft 5b1 of the motor 5b. Based on this, the operation of the motor 5b can drive the rotating seat 2 to rotate, thereby loosening the needle. A battery and a motor controller are installed in the outer annular cavity 5a2. The battery is a rechargeable lithium battery.

[0038] Please refer to Figure 2 The notch 2a has an inclined surface 2c on its lower side, similar to a car design, which ensures that the unscrewed needles fall more easily into the waste needle collection box 1. To facilitate the emptying of the collected non-needle tips, a cover plate 1b is provided on one side of the waste needle collection box 1.

[0039] In this embodiment, for example... Figure 3 As shown, in this embodiment, the elastic element 4 is a compression spring, with its upper end connected to the lower side of the pressure plate 3b and its lower end connected to the top of the rotating base 2. A pressure sensor 6 is provided between the lower side of the pressure plate 3b and the rotating base 2, and this pressure sensor 6 is associated with the control switch of the motor 5b. When the pressure applied by the needle 8 at the lower end of the insulin pen 7 causes the two sets of clamping components 3 to clamp the needle holder 8a, the pressure sensor 6 triggers a feedback signal to the control switch of the motor 5b, and then the motor 5b automatically turns on, thereby driving the loosening action, thus improving the automation level and ease of use of the automatic needle retriever.

[0040] Example 2

[0041] like Figure 7 As shown, a sharps container integrates the automatic insulin pen needle dispenser provided in Embodiment 1, and the container body constitutes a waste needle storage box 1.

Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
