Description

Technical Field

[0001] The utility model relates to the field of insulin pumps, in particular to an insulin pump connecting device. Background Art

[0002] The insulin pump connecting device is an important component of the insulin pump, which plays the role of connecting and installing the syringe. The insulin pump then squeezes the syringe in the device to work, and is used in conjunction with the connection of the infusion tube. It is widely used in various insulin pumps. When using the existing insulin pump connecting device, it is generally through the infusion tube to directly connect the syringe after the syringe is installed. However, when the infusion tube is inserted, there is no fixed part of the infusion tube, which makes the infusion tube easy to bend, making it inconvenient to use the infusion tube. Moreover, the infusion tube is only fixed by the connection with the syringe. Therefore, the infusion tube may fall off after long-term use and cannot be used stably. Utility Model Content

[0003] The main purpose of the utility model is to provide an insulin pump connecting device, which can effectively solve the technical problems raised by the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 3As shown, an insulin pump connecting device comprises an injection storage tube 1, a threaded docking groove 3 is provided on the top of the injection storage tube 1, a sealing end 4 is provided on the upper end of the injection storage tube 1, a threaded docking ring 5 is integrally formed on the lower end of the sealing end 4, two rotating shaft seats 7 are integrally formed on the upper end of the sealing end 4, a rotating shaft rod 8 is fixedly installed on the inner side of the rotating shaft seat 7, a connecting rod 10 is movably installed on the outer side of the rotating shaft rod 8, a torsion spring 9 is sleeved on the outer side of the rotating shaft rod 8 in front and behind the connecting rod 10, a sleeve tube 11 is movably installed on the upper end of the connecting rod 10, a tension spring 12 is movably installed inside the sleeve tube 11, a protective tube sleeve 14 is fixedly installed on one side of the sleeve tube 11, and an anti-slip groove 15 is provided on the inner side of the protective tube sleeve 14.

[0019] In this embodiment, a plurality of compression springs 2 are movably mounted on the inner wall of the injection storage tube 1. The plurality of compression springs 2 are arranged in a cross shape. The compression springs 2 can squeeze the syringe placed in the injection storage tube 1 to compress and position the syringe.

[0020] In this embodiment, the threaded docking ring 5 is screwed into the threaded docking groove 3 for mating connection, the sealing end head 4 is connected to the inside of the injection storage tube 1, and the outer side of the sealing end head 4 is integrally formed with anti-slip grooves 6, which can increase the resistance when rotating the sealing end head 4.

[0021] In this embodiment, the connecting rod 10 rotates around the rotating shaft rod 8, one end of the torsion spring 9 is fixedly connected to the connecting rod 10, and the torsion spring 9 is used to drive the connecting rod 10 to move to one side and apply force.

[0022] In this embodiment, the connecting rod 10 is inserted into the sleeve 11, the lower end of the tension spring 12 is fixedly connected to the upper end of the connecting rod 10, and a positioning buckle 13 is inserted into the other side of the sleeve 11, and the positioning buckle 13 is inserted into the interior of the connecting rod 10.

[0023] In this embodiment, the protective tube sleeve 14 is designed in a semicircular structure, and the two protective tube sleeves 14 are closely connected. The protective tube sleeves 14 are located above the sealing end 4, and the two protective tube sleeves 14 can be used to connect the infusion tube inserted into the sealing end 4.

[0024] It should be noted that the utility model is an insulin pump connection device. When in use, the injection storage tube 1 is installed at the output end of the insulin pump. By rotating the sealing end 4, the threaded docking ring 5 is separated from the threaded docking groove 3, and the sealing end 4 can be separated from the injection storage tube 1. The syringe is placed in the injection storage tube 1, and the threaded docking ring 5 and the threaded docking groove 3 are threadedly installed, so that the sealing end 4 seals the injection storage tube 1, thereby connecting the syringe to the injection storage tube 1, and the infusion tube is then connected to the end of the syringe through the opening on the sealing end 4. When the insulin pump is running, the output end of the insulin pump squeezes the syringe, so that the syringe squeezes out insulin for injection.

[0025] When the syringe is connected to the infusion tube, after the infusion tube passes through the sealing end 4, the two protective tube sleeves 14 fit the outer side of the infusion tube to protect the infusion tube, and the anti-slip groove 15 also fits the infusion tube to increase the connection resistance. Then, when the infusion tube is pulled, the infusion tube drives the protective tube sleeve 14 to move, so that the lower connecting rod 10 rotates around the rotating shaft rod 8, and at the same time, the torsion spring 9 pushes the connecting rod 10 on the rotating shaft rod 8 to apply reverse force, thereby offsetting the force when pulling the infusion tube, so that the infusion tube is always kept vertical to prevent bending with the connected syringe;

[0026] When the protective tube sleeve 14 is sleeved on the outside of the infusion tube and the positioning buckle 13 is pulled out, the tension spring 12 contracts, so that the tension spring 12 drives the sleeve tube 11 to move toward the connecting rod 10, thereby driving the protective tube sleeve 14 to move downward, so that the protective tube sleeve 14 also drives the infusion tube to maintain the downward force, so as to prevent the infusion tube and the syringe connected in the injection storage tube 1 from falling off.
