Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a non-invasive needle automatic locator for an infusion port. Background Art

[0002] In the medical field, as a vascular access device implanted in patients for a long time, the infusion port is widely used in various clinical treatments such as chemotherapy, nutritional support, and blood collection. The use of the infusion port greatly facilitates patients and medical staff, and reduces the pain and infection risk caused by repeated vascular punctures. However, in the maintenance process of the infusion port, especially the puncture operation of the non-invasive needle, there are still some problems to be solved urgently.

[0003] Traditional methods for maintaining infusion ports mainly rely on the experience and feel of nurses for manual positioning and puncture. Due to individual differences among patients, changes in the position of the port seat, and insufficient operation experience of nurses, the one-time needle insertion rate of non-invasive needles is often low. This not only increases the pain and discomfort of patients, but also may cause a series of complications such as vascular injury, local hematoma, and infection, seriously affecting the treatment effect and quality of life of patients.

[0004] In addition, traditional puncture methods also have the problems of cumbersome operation process and long time consumption. Nurses need to repeatedly adjust the puncture position to find the best needle insertion point, which not only increases the work burden of nurses, but also reduces work efficiency. At the same time, due to the lack of effective guiding and positioning devices during the puncture process.

[0005] Therefore, those skilled in the art have proposed a non-invasive needle automatic locator for an infusion port to solve the problems raised in the background art. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a non-invasive needle automatic locator for an infusion port, which realizes precise guidance and positioning of the non-invasive needle puncture process through a disc design and an annular bottle cap structure, aiming to solve the problems existing in the traditional infusion port maintenance process, improve the quality and efficiency of nursing work, and provide safer and more comfortable nursing services for patients.

[0007] A non-invasive needle automatic locator for an infusion port includes an infusion base, a connecting pipe is installed on the outer side wall of the infusion base, and a fixing ring is installed on the top end of the infusion base through the skin;

[0008] An adjusting mechanism, the adjusting mechanism is arranged on the outer side wall of the fixing ring, the adjusting mechanism includes a sliding collar, a plurality of sliding collars are arranged on the outer side wall of the fixing ring, a puncture groove is opened in the middle of the fixing ring, a placement groove is opened in the inner side wall of the fixing ring, and a driving member is installed on the inner side wall of the placement groove.

[0009] Preferably, a plurality of installation grooves are formed in the inner side wall of the fixing ring. The driving member includes a connecting gear which is rotatably connected to the inner side wall of the placing groove, and a connecting rack is meshed with the outer side wall of the connecting gear.

[0010] Preferably, the plurality of connecting racks are also fixedly connected to the outermost sliding collar, and the plurality of sliding collars form a collar for connecting with the infusion base.

[0011] Preferably, the connecting rack is also slidably connected to the inner side wall of the installation groove, and an anti-slip pad is also installed on the inner side wall of the installation groove.

[0012] Preferably, a support spring is fixedly connected to the outermost end of one of the connecting racks, and the support spring is also installed inside the installation groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through the design that the sizes of the plurality of sliding collars can be adjusted on the outside of the fixing ring, the device can be conveniently clamped on the outside of the infusion base, exposing the puncture groove. Through the clamping between the sliding collar and the infusion base, the puncture groove can be centered, which can assist the nurse in puncturing and facilitate the connection between the puncture needle and the infusion port.

[0022] The following further describes the embodiments of the present invention in detail in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] As shown in the attached Figure 1 to the attached Figure 6 as shown:

[0024] Embodiment 1: As shown Figures 1-3 herein, the present invention provides a non-invasive needle automatic locator for an infusion port, including an infusion base 1. A connecting tube 11 is installed on the outer side wall of the infusion base 1, and a fixing ring 2 is installed on the top of the infusion base 1 through the skin.

[0025] An adjusting mechanism is arranged on the outer side wall of the fixing ring 2. The adjusting mechanism includes sliding collar 21. A plurality of sliding collars 21 are arranged on the outer side wall of the fixing ring 2. A puncture groove 22 is opened in the middle of the fixing ring 2, and a placement groove 23 is opened on the inner side wall of the fixing ring 2. A driving member is installed on the inner side wall of the placement groove 23. By arranging the sliding collar 21 on the outside of the fixing ring 2, it is convenient to extend the volume of the fixing ring 2, so that the sliding collar 21 can be engaged with infusion bases 1 of different sizes.

[0026] Embodiment 2: As shown Figures 4-6 herein, the present invention provides a non-invasive needle automatic locator for an infusion port. A plurality of installation grooves 25 are opened on the inner side wall of the fixing ring 2. The driving member includes a connecting gear 24. The connecting gear 24 is rotatably connected to the inner side wall of the placement groove 23. A connecting rack 27 is meshed with the outer side wall of the connecting gear 24. A plurality of connecting racks 27 are also fixedly connected to the outermost sliding collar 21. A plurality of sliding collars 21 form a collar for connecting with the infusion base 1. By arranging the connecting gear 24, it is convenient to drive the plurality of connecting racks 27 on the outside to move outwards simultaneously, facilitating the simultaneous change of the inner diameter size.

[0027] The connecting rack 27 is also slidably connected to the inner side wall of the installation groove 25. An anti-slip pad 26 is also installed on the inner side wall of the installation groove 25. The outermost end of one of the connecting racks 27 is also fixedly connected with a support spring 28. The support spring 28 is also installed inside the installation groove 25. By arranging the inner support spring 28 or the anti-slip pad 26, the connecting rack 27 can be positioned, and it can be selected according to different needs.

[0028] Working principle: When this device needs to be used, first, according to the size of the infusion base 1, then pull one of the sliding collars 21, so that the sliding collar 21 drives one of the connecting racks 27 to move. The connecting rack 27 will drive the connecting gear 24 to rotate. The rotation of the connecting gear 24 can simultaneously drive the remaining several connecting racks 27 to move outwards. The movement of multiple connecting racks 27 will drive the remaining sliding collars 21 to also open outwards, expanding to a size similar to that of the infusion base 1. If there is a support spring 28 inside, the support spring 28 will pull the connecting rack 27 and the sliding collar 21 to reset, so that the sliding collar 21 is engaged with the infusion base 1. If there is an anti-slip pad 26 inside, after installing it on the infusion base 1, press the sliding collar 21 inwards to make it engaged with the infusion base 1, and then pass the needle through the connecting gear 24.
