[0024] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0025] The terms "comprises" and "having" and any variations thereof in the description and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such process, method, product or apparatus.
[0026] One of the preferred embodiments of this application is as follows: Figures 1 to 6As shown, an auxiliary device for an infusion tube comprises an infusion tube 1 and an extension piece 2 installed on the infusion tube 1; a storage shell 3 is installed on the side of the extension piece 2, and the storage shell 3 can store the extension piece 2. The storage shell 3 and the extension piece 2 are locked and fixed by a locking structure 4; when extending, the locking structure 4 can be driven to release the lock of the extension piece 2, so that the extension piece 2 can be rotated along the axial direction of the storage shell 3. The rotation of the extension piece 2 can make the extension piece 2 extend out of the storage shell 3, and then the locking structure 4 can lock and fix the extended extension piece 2, so that The overall length of the infusion tube 1 is lengthened, which is convenient for better adapting to different infusion scenarios and improving the practicality and safety of the device; when it is stored, the locking structure 4 releases the lock on the extension piece 2, and then the extension piece 2 can be rotated in the storage shell 3 and along the axial direction of the storage shell 3, and then the extended extension piece 2 will be re-stored in the storage shell 3. At this time, the locking structure 4 can lock and fix the stored extension piece 2, thereby shortening the length of the infusion tube 1, preventing the infusion tube 1 from being too long and causing accumulation or knotting, thereby adapting to different infusion environments and improving the patient's infusion experience.
[0027] In this embodiment, Figure 1 、 Figure 3 and Figure 5 As shown, it can be understood that a rotating column 31 is installed in the storage shell 3, and the extension piece 2 is installed at the top of the rotating column 31, so that the extension piece 2 can be smoothly rotated in the storage shell 3, thereby improving the experience of operating the device. At the same time, a storage groove 32 is opened on the outer wall of the rotating column 31, thereby facilitating better storage of the extension piece 2 and improving the storage effect.
[0028] In this embodiment, Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the extension member 2 includes a disc 21, an extension tube 22 and a connecting portion 23; the disc 21 is installed at the top of the rotating column 31, the disc 21 and the infusion tube 1 are connected, the extension tube 22 is installed through the bottom of the disc 21, and the extension tube 22 matches the receiving groove 32, and the connecting portion 23 is connected to one end of the extension tube 22; when extending, the locking structure 4 releases the lock on the rotating column 31, and the disc 21 can be rotated at this time, so that the disc 21 can rotate along the axial direction of the rotating column 31, and the rotation of the disc 21 can make the disc 21 in the receiving groove The extension tube 22 in 32 is separated from the storage groove 32, so that the extension tube 22 extends out of the storage shell 3, thereby lengthening the overall length of the infusion tube 1; when storing, the locking structure 4 releases the lock on the rotating column 31, and the disc 21 can be rotated in the opposite direction. The rotation of the disc 21 can rotate with the extension tube 22, and the rotation of the extension tube 22 can cooperate with the storage groove 32, thereby allowing the extension tube 22 to enter the storage groove 32 for storage, thereby shortening the overall length of the infusion tube 1, thereby facilitating better adjustment of the overall length of the device and improving the practicality of the device.
[0029] In this embodiment, Figures 1 to 3 As shown, it should be known that the infusion tube 1 includes an infusion part 11 and a needle head 12; one end of the infusion part 11 is connected to the hanging water bottle, the other end of the infusion part 11 is connected to the disc 21, and one end of the needle head 12 is connected to the connecting part 23, and then the overall length of the infusion tube 1 can be adjusted by adjusting the length of the extension tube 22, thereby facilitating better improvement of the practicality and safety of the device.
[0030] In this embodiment, Figure 3 and Figure 4 As shown, it can be understood that a plurality of injection ports 211 are provided on the side of the disc 21. By providing a plurality of injection ports 211, different drugs can be better injected at the same time, thereby improving the practicality of the device and reducing the drug administration time. A heparin cap is provided in the injection port 211, which can better ensure the safety of the injection port 211. The provision of a plurality of injection ports 211 can prevent one injection port 211 from having a large gap in the heparin cap due to multiple drug administrations, thereby causing infection. The provision of a plurality of injection ports 211 can, on the one hand, allow drug administration at the same time, and on the other hand, reduce damage to the heparin cap, thereby improving the sealing and safety of the device.
[0031] It is understandable that when administering an injection, the drug is generally injected from the needle head 12 (such as the infusion line on the indwelling needle) through a micropump or directly through a syringe. If multiple doses are required, the syringe needs to be repeatedly administered from the infusion line 1, which may cause the heparin cap in the infusion line 1 to be damaged and easily cause infection. When multiple infusion lines 1 are provided for administration, the needle head 12 lines on the patient's hand will be more complicated, thereby affecting the patient's hand movement. Therefore, in order to better improve the patient's infusion experience , reducing the risk of needle injury and the risk of the needle head 12 coming out. A disc 21 is provided through the infusion part 11, and a plurality of injection ports 211 for drug administration are opened on the disc 21, so that there is no extra infusion tube 1 at the needle head 12 of the patient's hand. When administering the drug, the drug can be administered at the same time to improve the drug administration efficiency, or when administering the drug, different injection ports 211 can be selected for administration to reduce the damage efficiency of the heparin cap in the injection port 211, improve the sealing and safety of the device, and improve the comfort of the patient's hand.
[0032] In this embodiment, Figure 3 and Figure 4 As shown, it should be known that in order to prevent the drug in the disc 21 from flowing back after administration, the axial angle between the injection port 211 and the disc 21 is less than 90°. Therefore, after administration, the drug can be introduced into the human body through the disc 21, which facilitates better administration and improves the practicality of the device.
[0033] In this embodiment, Figure 1 and Figure 4 As shown, a threaded sleeve is provided on the side of the connecting portion 23 , and the threaded sleeve is threadedly penetrated and sealed with the needle head 12 , so as to facilitate better connection with the needle head 12 .
[0034] It is understandable that if Figures 1 to 4 The needle head 12 and the infusion part 11 of a general infusion tube 1 are plugged into each other. In this way, during infusion, the needle head 12 and the infusion part 11 may be separated by a mistaken operation by the personnel, thereby causing infusion failure. Therefore, a threaded sleeve is installed on the side of the connecting part 23, and a threaded block is provided on the needle head 12. On the one hand, the needle head 12 can be plugged into the connecting part 23, and on the other hand, the threaded connection between the needle head 12 and the connecting part 23 can be better achieved through threaded cooperation, so as to better prevent the patient from pulling and breaking free.
[0035] In this embodiment, Figures 3 to 6As shown, the locking structure 4 includes a locking block 41 elastically mounted in the storage shell 3 by a spring, and a gear 42 mounted on the side of the rotating column 31; the locking block 41 and the gear 42 are meshed; when extending, the locking block 41 is elastically pulled, and the locking block 41 is away from the gear 42, thereby unlocking the rotating column 31. When the disc 21 is rotated, the multiple liquid injection ports 211 on the side of the disc 21 can be rotated out of the storage shell 3, and at the same time, the extension tube 22 set in the storage groove 32 is extended out of the storage groove 32. At this time, the locking block 41 is released and the locking block 41 can be elastically reset and re-engaged with the gear 42. When the locking block 41 is elastically stretched, the locking block 41 is separated from the gear 42, and the rotating column 31 is unlocked. At this time, the rotation of the disc 21 can drive the rotating column 31 to rotate, and the rotation of the rotating column 31 can cause the extension tube 22 to rotate. The extension tube 22 rotates and can re-enter the storage groove 32 for storage. At this time, the liquid injection port 211 also rotates into the storage shell 3, so as to better store and protect the liquid injection port 211, thereby improving the safety and practicality of the device.
[0036] It is understandable that if Figure 5 As shown, in order to prevent the extension tube 22 from interfering with the gear 42, a protective block is provided at the upper end of the gear 42, and the opening at the bottom end of the storage groove 32 is provided at the upper end of the protective block, so that when the extension tube 22 is stored, the extension tube 22 does not contact the gear 42, thereby better protecting the extension tube 22 and improving the practicality and safety of the device.
[0037] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
