[0022] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] See also Figures 1 to 4 The infusion port in the utility model includes an injection seat 10 and a catheter 20. The interior of the injection seat 10 is hollowed out to form a liquid storage tank 111. The catheter 20 is arranged on one side of the injection seat 10 and communicates with the liquid storage tank 111. The peripheral surface of the injection seat 10 is provided with a positioning groove 31 and an elastic positioning ring 32 for matching the positioning groove 31. During injection, the elastic positioning ring 32 is attached to the positioning groove 31 outside the patient's body surface, thereby tightening the patient's skin and highlighting the outline of the injection seat 10.

[0027] The elastic positioning ring 32 is attached to the positioning slot 31 outside the patient's body surface, thereby tightening the patient's skin to highlight the outline of the injection seat 10, so that medical staff can quickly and accurately locate the puncture point, greatly improving the accuracy and efficiency of puncture.

[0028] like Figure 2 As shown, the injection seat 10 includes a base 11, a cover body 12 and a piercing partition 13. The base 11 is concave to form the liquid storage tank 111. The cover body 12 is sealed and connected to the base 11. The piercing partition 13 is arranged on the cover body 12 and corresponds to the liquid storage tank 111.

[0029] It can be understood that the piercing septum 13 is located on the cover 12 and corresponds to the liquid reservoir 111, which allows the infusion needle to pass through and penetrate into the liquid reservoir 111, thereby achieving drug infusion. The design of the piercing septum 13 not only ensures the smooth progress of the infusion process, but also effectively prevents the leakage of the drug solution and the invasion of external bacteria. In this embodiment, the piercing septum 13 is specifically a silicone plug.

[0030] Preferably, in this embodiment, the base 11 and the cover 12 are connected by ultrasonic welding. The advantages of ultrasonic plastic welding are fast welding speed, high welding strength, good sealing, low cost, clean and pollution-free, no damage to the workpiece, and ensuring that there are no foreign matter and impurities in the infusion port. In addition, the ultrasonic welding process is stable, and all welding parameters can be tracked and monitored by the software system, so once a fault is found, it is easy to eliminate and maintain.

[0031] For further information, see Figure 4 The positioning slot 31 is provided on the peripheral surface of the cover body 12. It can be understood that the positioning slot 31 is provided on the peripheral surface of the cover body 12, which is closer to the patient's skin epidermis, so that the elastic positioning ring 32 can more effectively tighten the patient's skin, highlight the contour of the cover body 12, and improve the accuracy and efficiency of the puncture operation.

[0032] It should be noted that the elastic positioning ring 32 in this embodiment can be made of materials such as rubber or silicone and is a disposable product.

[0033] like Figure 2 and Figure 3 As shown, a connecting tube 41 is fixedly provided on the base 11, one end of the connecting tube 41 is connected to the liquid storage tank 111 through a liquid guide groove 42, and the other end extends out of the base 11, and the catheter 20 is connected to the end of the connecting tube 41 extending out of the base 11 through a catheter lock 43.

[0034] Furthermore, the upper surface of the base 11 is provided with a sealing groove 51 surrounding the liquid storage tank 111, and a sealing ring 52 is provided in the sealing groove 51. When the base 11 and the cover 12 are connected as one, the sealing ring 52 can isolate the liquid medicine in the liquid storage tank 111, prevent the liquid medicine from leaking out from the inside of the infusion port, and improve the sealing performance of the infusion port.

[0035] Furthermore, the connecting pipe 41 is provided with a valve (not shown), and the flow amplitude of the liquid medicine can be controlled by the valve.

[0036] In summary, the infusion port in the above-mentioned embodiment of the utility model is connected to the positioning slot 31 outside the patient's body surface through the elastic positioning ring 32, thereby tightening the patient's skin to highlight the outline of the injection seat 10, so that medical staff can quickly and accurately locate the puncture point, greatly improving the accuracy and efficiency of puncture.

[0037] See also Figure 5 , shown is an infusion port in the second embodiment of the utility model. The difference between the infusion port in this embodiment and the infusion port in the first embodiment is that: a panel 60 is formed protruding from the upper surface of the cover body 12, the puncture septum 13 is arranged in the panel 60 and corresponds to the liquid storage tank 111, and the positioning card slot 31 is arranged on the peripheral surface of the panel 60. It can be understood that the contour of the panel 60 is the contour of the puncture septum 13. By setting the positioning card slot 31 on the peripheral surface of the panel 60, after the elastic positioning ring 32 is set, the patient's skin can be tightened to directly highlight the contour of the puncture septum 13. Compared with the scheme of highlighting the contour of the cover body 12 in the first embodiment, the accuracy of the puncture operation is further improved.

[0038] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
