Description

A kind of transfusion device impermeability/aeration automatic detection device
Technical field
The utility model relates to a kind of checkout equipment, especially relates to a kind of checkout equipment of transfusion device.
Background technology
The aseptic apparatus full name is disposable use aseptic medical equipment, is meant aseptic, apyrogeneity, through being up to the standards, the medicine equipment of disposable direct use before the deadline.Disposable infusion set belongs to aseptic apparatus.
Aseptic medical equipment automated arm industry is flourish in recent years, but present stage aseptic medical equipment enterprise automaticity also very low, its automaticity also has very big room for promotion.Such as; The production assembling process of disposable infusion set is still manually-operated basically, and its main cause is owing to be flexiplast spare by dress group new product; Be difficult to realize automatic assembling than conventional products, also do not realize the whole-process automatic assembling of disposable infusion set so far.But being medical device industry, the market development megatrend generally presses for technological innovation, upgrading transition to change the labor-intensive present situation; Also be that the research and development of whole-process automatic package technique are imperative; Thereby the Automatic Measurement Technique of disposable transfusion device and Design of device exploitation, very important aspect its automatic package technique enforcement of promotion.Disposable infusion set impermeability and aeration are for must examine performance, but in the present enterprise production, this performance is main with manual detection still, is difficult to adapt to the automated production requirement.Like publication number is that the Chinese patent of CN201795901U discloses a kind of transfusion device gas and leaks detecting device, can be effective to solve conveniently, the problem of fast detecting transfusion device gas leakage.Its technical scheme is: comprise glass tube, needle tubing and air valve, needle tubing places in the glass tube, and glass tube inner aqueous layer top is air layer; Needle tubing is suitable for reading inserts in the air layer, and glass tube bottom one end is connected with source of the gas, and the other end is connected with the air valve bottom through skirt; Air valve structure is, valve gap is equipped with through connector in valve body top, and bonnet lower is equipped with spool in valve body; Valve inner hollow constitutes the inwall gas circuit; Outlet is arranged on the valve gap, and the spring that is contained in the valve body is equipped with in the spool lower end, and valve body lower portion is linked together by connector and skirt.During use, measured piece pack into valve gap suitable for reading in, depress by the side part; Its gas port links to each other with spool, and gas flows through the spool side opening and arrives gas port from the bottom, seals the valve gap outlet simultaneously; The glass tube upper end forms pressure reduction with source of the gas if assembly leaks gas then, because needle tubing is suitable for reading in air, goes into to manage top so gas divides with the bubbling form; Can conveniently check the gas leakage situation this moment: if assembly is air tight, then pressure reduction is zero up and down, and the water surface remains static; Leak hunting equally after the completion, because the effect of spring moves on the spool, O-ring seal is sealed spool side opening and whole inwall gas circuit, and system does not have pressure reduction, and the water surface also remains static.But this technical scheme is through operator's visual inspection bubbling situation, and whether device itself have problem, also is not easy to be observed, and therefore, uses this device to detect and unreliable, and automaticity is not high yet, and testing process meeting consuming time is long.
Summary of the invention
The utility model mainly is to solve existing in prior technology to detect unreliable, technical matterss such as automaticity is not high, testing process length consuming time, and kind transfusion device impermeability/aeration automatic detection device that a kind of automaticity is high, easy to detect, have the System self-test function is provided.
