Problems solved by technology
[0004] However, the above-mentioned existing ultrasonic cleaning device needs to soak the entire sampling needle or most of the sampling needle in the cleaning solution of the container, which lengthens the stroke of the sampling needle. This process is not only time-consuming and inconvenient, but also increases Eliminates the risk of damage from accidental needle contact with the container
Since the bottom and side walls of the container have openings for liquid inlet and outlet, the medium is discontinuous, which affects the transmission of ultrasound
Moreover, the size of the bottom opening is limited, which is not conducive to liquid drainage and liquid supply, and the cleaning liquid is easy to overflow from the top of the container
It can be seen that the ultrasonic cleaning device in the prior art has certain defects, and it is very inconvenient to use in automatic instruments such as biochemical luminescence

Embodiment Construction
[0021] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0022] The invention proposes an ultrasonic cleaning mechanism, which can clean the sampling needle of the biochemical luminescence measuring instrument by means of a spring-type scouring and cleaning method. figure 1 A three-dimensional schematic diagram of an ultrasonic cleaning mechanism for a sampling needle is shown. The basic principle of the present invention is to adopt the combination of spring-type hydraulic cleaning and ultrasonic cleaning, and add high-intensity ultrasonic waves at the same time of hydraulic cleaning, and use high-intensity ultrasonic waves to generate cavitation effects in the cleaning liquid, acting on the cleaned The wall of the sample needle can achieve efficient and fast cleaning effect.

The invention provides an ultrasonic cleaning mechanism and a cleaning method for a sampling pin. The ultrasonic cleaning mechanism comprises an ultrasonic transducer and an ultrasonic focusing body; the top of the ultrasonic focusing body comprises an end part provided with a groove; the groove comprises a closed bottom surface. According to the invention, fountain type washing and cleaning different from the prior art is realized, and is combined with the ultrasonic cleaning, so that the sampling pin is dispensed with immersing in cleaning solution; damaging probability of the sampling pin is reduced; the ultrasonic cleaning mechanism has the effects that the ultrasonic cleaning mechanism is convenient in cleaning operation, the cleaning speed is accelerated, and the equipment structure is simplified.
Description
technical field [0001] The invention relates to the field of biochemical luminescence measuring instrument equipment, and more specifically, to an ultrasonic cleaning mechanism and cleaning method for a sample needle. Background technique [0002] Biochemiluminescent immunoassay has the advantages of high sensitivity, wide linear range, convenient and fast operation, and has been widely used in the field of clinical testing. At present, bioluminescent measuring instruments based on biochemiluminescent immunoassays have become mature medical diagnostic equipment. However, how to effectively reduce the carryover pollution produced by the sample needle of the bioluminescence measuring instrument has always been an important issue. [0003] A common method to solve this problem in the prior art includes using disposable suction tips, but the cost of this method is relatively high. In the prior art, there are also methods and devices for cleaning the sampling needle using ultra...
