Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an integrated liquid circuit plate and a machining method for a flow guiding hole of the integrated liquid circuit plate. The machining method for the flow guiding hole of the integrated liquid circuit plate comprises the following steps that an initial flow guiding hole of the integrated liquid circuit plate is obtained through a machining mode; and high-temperature gas is injected into the initial flow guiding hole, the inner wall of the initial flow guiding hole can be melted down through the high-temperature gas, and then, the flow guiding hole of the integrated liquid circuit plate is obtained after cooling and curing. Specifically, the temperature of the high-temperature gas is 1-10 DEG C higher than the melting temperature of an integrated liquid circuit plate material. According to the integrated liquid circuit plate and the machining method for the flow guiding hole of the integrated liquid circuit plate, easiness and practicality are achieved, operation is convenient, the efficiency is high, the effect is good, angular tool marks on the surface of the inner wall of the flow guiding hole can become smooth and flat, and the surface smoothness of the inner wall of the flow guiding hole is greatly improved, so that liquid flows more smoothly, and the liquid attachment phenomenon is prevented.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a liquid circuit structure in a medical device, in particular to an integrated liquid circuit board and a processing method for a diversion hole of the integrated liquid circuit board. Background technique [0002] The liquid circuit structure system is widely used in medical equipment, such as biochemical analyzers, medical testing instruments, etc., will contain a liquid circuit structure system. Taking the liquid circuit structure system of a hematology analyzer as an example, it is mainly composed of components such as pumps, valves, motors, syringes, counting tanks and rubber hoses. These components are assembled on one or several substrates in a certain order and layout , and communicate with each other with rubber hoses to form a liquid circuit structure system. However, all the components of the liquid circuit structure system are installed on one or more substrate...
