Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

The following examples are given for the purpose of illustrating the present invention in a clear manner and are not intended to limit the scope of the present invention. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art based on the following description, and it is within the spirit of the present invention that such variations and modifications are within the scope of the present invention.

Referring to the figures, the transfusion port base fixer comprises a hollow conical fixing shell 1 with two through upper and lower ends, referring to fig. 1 and 2, an opening 2 is arranged on the side wall of the fixing shell 1, the opening 2 and the side wall are of the same thickness, the two ends of the opening respectively extend to the top surface and the bottom surface of the fixing shell 1, a lining block 3 is arranged on the opposite side of the opening 2, the lining block 3 and the fixing shell 1 are integrally formed, and the bottom surface of the lining block 3 is flush with the bottom surface of the fixing shell 1.

Preferably, referring to fig. 3 and 4, the bottom of the stationary casing 1 and the bottom of the pad 3 are provided with a gasket 4. The pad 4 is soft and does not feel uncomfortable when pressed against the skin of the patient.

Preferably, referring to fig. 5, the gasket 4 includes a first gasket 41 and a second gasket 42, the first gasket 41 and the second gasket 42 are respectively shaped to correspond to the circular ring-shaped bottom of the stationary case 1 and the bottom surface of the pad 3, and the circular ring-shaped bottom of the stationary case 1 and the bottom surface of the pad 3 are respectively embedded and fixed in the first gasket 41 and the second gasket 42.
