Description

Technical Field

[0001] The utility model relates to the technical field of infusion ports, in particular to a matching needle for an infusion port. Background Art

[0002] In addition to PICC, the central venous device currently used clinically for cancer patients is also called an infusion port. Part of the infusion port remains in the human body, and the other step requires external access to the output liquid medicine. The infusion needle head can be directly connected to the internal infusion port when in use, but due to the inconvenience of fixation, the infusion needle head needs to be additionally fixed. At the same time, since the infusion needle head is made of plastic, it will cause pressure on the human skin for a long time, causing additional trauma.

[0003] To this end, we propose an infusion port matching needle to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provides a matching needle for an infusion port.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A needle matching an infusion port includes a puncture needle seat and needle wings. The upper end surface of the puncture needle seat is provided with needle wings, and a needle sticking assembly is arranged in the puncture needle seat. The needle sticking assembly is initially wrapped and arranged in the puncture needle seat, and the puncture needle passes through the needle sticking assembly and extends downward.

[0007] Preferably, the needle patch assembly comprises two layers, the upper layer is the needle patch wing layer, and the lower layer is the needle patch base layer, and the needle patch wing layer is attached to the upper layer of the needle patch base layer.

[0008] Preferably, the upper needle patch wing layer and the lower needle patch base layer are both soft silicone layers.

[0009] Preferably, a diaphragm is provided between the upper needle patch wing layer and the lower needle patch base layer.

[0010] The ball is connected to the second leather ring layer through a limiting column.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By cooperating with the needle patch wing layer and the needle patch base layer, after the needle wing and the puncture needle seat are removed, only the needle patch wing layer and the patch base layer are left. Since the existing technology requires manual re-finding of the medical tape to fit the injection position, the needle can be removed by flipping the outer needle patch wing layer part when the needle is removed through the needle patch wing layer and the needle patch base layer. The base layer can directly avoid infection, thereby improving the convenience and safety of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] At present, in addition to PICC, there is another central venous device called an infusion port for cancer patients in clinical use. A part of the infusion port remains in the human body, that is, the injection seat 7; another step is to receive the output liquid externally, and the infusion needle head can be directly connected to the internal injection seat 7 when in use, but due to the inconvenience of fixing, the infusion needle head needs to be additionally fixed. At the same time, since the infusion needle head is made of plastic material, it will cause pressure on the human skin for a long time, causing additional trauma, so refer to Figure 1-3 This scheme designs a matching needle for an infusion port, including a puncture needle seat 1 and a needle wing 2. The upper end surface of the puncture needle seat 1 is provided with a needle wing 2, and a needle sticking assembly 3 is provided inside the puncture needle seat 1. The needle sticking assembly 3 is initially wrapped and arranged in the puncture needle seat 1, and the puncture needle 4 passes through the needle sticking assembly 3 and extends downward.

[0020] Specifically: the needle patch assembly 1 includes two layers, the upper layer is the needle patch wing layer 5, and the lower layer is the needle patch base layer 6. The needle patch wing layer 5 is attached to the upper layer of the needle patch base layer 6. Since the traditional method requires manual re-finding of medical tape to fit the needle insertion position, this will not only cause operational problems, but also easily cause infection problems. Therefore, in this solution, after removing the puncture needle seat 1 and the needle wing 2, the needle patch assembly 3 is still retained, and the needle patch wing layer 5 on the needle patch assembly 3 is used to separate it from the needle patch base layer 6 to form an upturned state, thereby achieving the operation of removing the needle. The base layer can directly avoid infection and improve the convenience and safety of operation.

[0021] The silicone layer 6 only covers the top position of the needle patch assembly 5, the central part of the silicone layer 6 is fixedly connected to the top of the docking head, and the rest of the silicone layer 6 is separated from the docking head. A diaphragm is arranged between the docking head and the silicone layer 6 to prevent the two from sticking together. Therefore, after taking away the needle wing 11, the silicone layer 6 can be directly flipped up, and the infusion needle 3 can be easily pulled out by flipping the silicone layer 6, thereby improving the convenience of operation.

[0022] In order to achieve better practicality, the upper needle patch wing layer 5 and the lower needle patch base layer 6 are both soft silicone layers. Therefore, when holding the upper needle patch wing layer 5, it will not slip out of your hand and will not cause discomfort to the skin during the storage period. At the same time, a diaphragm is provided between the upper needle patch wing layer 5 and the lower needle patch base layer 6 to facilitate separation of the two in the future. The diaphragm is used to separate the upper needle patch wing layer 5 and the lower needle patch base layer 6, so that the upper needle patch wing layer 5 can be better flipped.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
