Description

Technical Field

[0001] This utility model relates to the field of insulin pump technology, specifically to an infusion pump used for insulin therapy injection. Background Technology

[0002] An insulin infusion pump, also known as an insulin pump or continuous injector, is a medical device used to deliver insulin into the body to control blood sugar levels. The insulin infusion pump mainly consists of a syringe, a catheter, a remote control, and a battery. The syringe is filled with insulin liquid, the catheter connects the syringe and the needle, the remote control is used to control the injection speed and dosage, and the battery provides power. Based on the preset basal rate and pre-meal bolus, the insulin liquid is delivered to the subcutaneous injection site through the catheter.

[0003] Insulin pumps are usually clipped to the patient's waistband. Because they are clipped to the waistband, the position of the insulin pump can easily change. When the user sits down or bends over, the insulin pump may slide upwards, shift, or fall off. The shifting or falling of the insulin pump causes the needle to move under the skin, and the patient will feel obvious pain and stinging. Therefore, it is necessary to provide a way to stably fix it to the patient's waistband to avoid the risk of the insulin pump falling off. Utility Model Content

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 protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is an infusion pump for insulin therapy injection, comprising:

[0028] An infusion pump 11 is provided, with a control button 12 fixed on one side. An insulin bottle 13 is placed inside the infusion pump 11, with an infusion tube 14 connected to one end of the insulin bottle 13 and a needle 15 connected to the end of the infusion tube 14.

[0029] The infusion pump 11 is the core component of the entire insulin infusion system, mainly responsible for storing and delivering insulin. The control button 12 is an important interface for the user to interact with the infusion pump 11. The insulin bottle 13 is a container used to store the insulin solution, ensuring the stability and safety of insulin during storage and infusion. One end of the infusion tube 14 is connected to the insulin bottle 13, and the other end is connected to the needle 15, which acts as a bridge to ensure that insulin can be smoothly delivered from the insulin bottle 13 to the needle 15 and then injected into the patient's body.

[0030] The fixing component includes a limiting frame 21, a movable plate 22, a fixing hole 23, a fixing block 24, and a slot 25. The limiting frame 21 is fixed to one side of the rear wall of the injection pump 11. The movable plate 22 slides through the inside of the limiting frame 21. The fixing hole 23 is opened on one side of the movable plate 22. The fixing block 24 is fixed on the other side of the injection pump 11. The slot 25 is opened on one side of the fixing block 24, and the end of the movable plate 22 extends into the inside of the slot 25.

[0031] The limiting frame 21 is fixed to one side of the rear wall of the injection pump 11, providing a clear movement trajectory and range for the movable plate 22. The main function of the movable plate 22 is to firmly fix the injection pump 11 to the trouser loop. Through the coordinated action with components such as the locking post 28 and the locking slot 25, the stable wearing of the injection pump 11 is achieved.

[0032] The movable plate 22 is T-shaped. The fixed block 24 has an installation hole 26 inside. The installation hole 26 passes through the slot 25. A spring 27 is fixed inside the installation hole 26. One end of the spring 27 is fixed with a locking post 28. The fixing hole 23 is inserted into the slot 25, and the locking post 28 extends into the fixing hole 23.

[0033] The main function of the spring 27 is to provide elastic force so that the locking post 28 can be tightly locked in the fixing hole 23, thereby achieving a firm fixation between the movable plate 22 and the slot 25. Under the action of the spring 27, the locking post 28 extends into the fixing hole 23 and fits tightly with the fixing hole 23 to fix the movable plate 22.

[0034] Working principle:

[0035] Place the insulin bottle 13 into the infusion pump 11, then connect the infusion tubing 14 to the insulin bottle 13, disinfect the skin, insert the needle 15 into the skin, then move the movable plate 22 outward so that the movable plate 22 passes through the trouser loop, push the movable plate 22 into the slot 25, the movable plate 22 will contact the locking post 28 when it enters the slot 25, press the locking post 28 inward so that the spring 27 is compressed in the mounting hole 26, when the fixing hole 23 is aligned with the mounting hole 26, the spring 27 will return to its original shape, driving the locking post 28 to move into the fixing hole 23, the locking post 28 is locked into the fixing hole 23, and the movable plate 22 is positioned on the patient's trouser loop;

[0036] This step requires no complicated procedures, and patients do not need to worry frequently about the insulin pump falling off or shifting during daily activities.

[0037] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The protective component includes a fixing frame 31, a limiting groove 32, and a threaded hole 33. The fixing frame 31 is fixed to one side of the injection pump 11. The limiting groove 32 is opened inside the fixing frame 31. The threaded hole 33 is opened on one side of the limiting groove 32 and the threaded hole 33 and the limiting groove 32 are interconnected. A threaded rod 34 is threaded through the threaded hole 33. A bearing 35 is rotatably installed at one end of the threaded rod 34. A baffle 36 is fixed on one side of the bearing 35. The baffle 36 is U-shaped and has arc-shaped grooves on both sides inside the baffle 36.

[0039] The fixing frame 31 serves as the basic structure of the entire protective assembly, providing stable support and positioning for other components. The limiting groove 32 and the baffle 36 cooperate with each other to form a dual positioning structure for the insulin bottle 13. By rotating the threaded rod 34, the baffle 36 can be moved back and forth within the limiting groove 32. When the threaded rod 34 rotates, due to the action of the thread, it will move linearly along the axis of the threaded hole 33. This linear motion is transmitted to the baffle 36 through the bearing 35, thereby driving the baffle 36 to move accordingly, realizing the fixing and releasing operation of the insulin bottle 13.

[0040] Working principle:

[0041] When placing the insulin bottle 13 into the infusion pump 11, the threaded rod 34 should first be rotated counterclockwise to move the threaded rod 34 outward within the threaded hole 33. With the connection of the bearing 35, the baffle 36 moves outward, allowing the insulin bottle 13 to be easily placed into the infusion pump 11. Then, the threaded rod 34 is rotated clockwise to move the threaded rod 34 into the threaded hole 33, simultaneously driving the baffle 36 to move inward, thus limiting the insulin bottle 13 inside the fixing frame 31 and preventing the insulin bottle 13 from falling out during injection.

[0042] This step effectively ensures the safety and continuity of the injection process, avoiding infusion interruptions that may occur if the insulin vial 13 falls out.
