Description

Method for manufacturing blood pressure cuff and blood pressure cuff Technical Field The application relates to the technical field of cuff processing, in particular to a manufacturing method of a blood pressure cuff and the blood pressure cuff. Background The blood pressure cuff is a key component in medical equipment such as an electronic blood pressure monitor and a dynamic blood pressure monitor. The existing manufacturing process of the blood pressure cuff generally follows the flow of fixing the support structure first, assembling the air bag again and packaging the main body finally. However, in this manufacturing process, particularly, the assembling of the support sheet and the airbag is completed synchronously in the process of shaping the cuff body, that is, the support sheet is generally required to be rolled or preformed first and then fixed inside the cuff body in the sewing process, which has high requirements on the proficiency of operators, and the assembling space is limited, so that the problems of inaccurate positioning, wrinkles or displacement are likely to occur. Disclosure of Invention The application provides a manufacturing method of a blood pressure cuff and the blood pressure cuff, which simplify the process flow, simplify the processing and improve the assembly efficiency in a modularized assembly mode. To this end, the present application provides a method of manufacturing a blood pressure cuff, the method comprising the steps of: providing a first band-shaped body, a second band-shaped body and a third band-shaped body, and sewing the second band-shaped body and the third band-shaped body at two ends of the first band-shaped body respectively to form a sleeve belt main body with a containing cavity; Overlapping the free ends of the second and third bands to form an opening in communication with the receiving cavity; Providing a support sheet and an airbag, and arranging the airbag on the support sheet to form an airbag assembly; The air bag component is arranged in the accommodating cavity through the opening, so that the supporting sheet covers the inner sides of the second band-shaped body and the third band-shaped body, and the air bag faces the first band-shaped body to form the blood pressure cuff.
