Description

Technical area

This application relates to a part for medical device cleaners or a disposable multi-position valve for medical device cleaners.

State of the art

The ultrasonic cleaning machine is a cleaning device for medical devices that is currently widely used, particularly in the cleaning of the lumen-type medical devices and in the use of ultrasonic cleaning machines. Since lumen-type medical devices are usually smaller in diameter but longer in body, medical personnel normally place lumen-type medical devices in a cleaning basket or ultrasonic cleaning cleaning containers. Current ultrasonic cleaning machines as lumen-type medical devices have two major shortcomings. On the one hand, since the medical devices are stacked on each other during the cleaning process, the ultrasonic radiation is constantly absorbed by the wall of the medical devices as it propagates. The greater the distance from the ultrasonic transducer, the weaker the oscillation frequency of the ultrasonic wave, which leads to a reduction in the cleaning effect of the lumen-like medical devices. On the other hand, due to the different adhesion of the soil attached to lumen-like medical devices, particularly in the lumen, and due to the surface tension and the gravity of the soil, the dirt adhesion to the inner wall of the lumen is greatly increased. When purifying lumenal medical devices centrally, it is difficult to ensure that the debris in the lumen can be completely detached under the action of ultrasonic vibration, especially for a few lumens of medical devices that have high adhesive force and require suction cleaning. Centralized cleaning is difficult to completely clean the dirt within the lumen. Since the ultrasonic vibrations are continuously absorbed during the propagation process, the amplitude of the ultrasonic waves reaching the lumen is greatly reduced, and their cleaning ability is also greatly reduced.

For the shortcomings of centralized cleaning, technicians in the field are also constantly improving the ultrasonic cleaning machine for lumen-type medical devices and developing the intraluminal perfusion-cleaning technology. One Chinese Patent No. ZL 201520315754.6 discloses a laparoscopic ultrasonic cleaning machine. With the use of the perfusion pump built into the housing and the perfusion port associated with the laparoscope, the cleaning fluid is pumped into the lumen of the laparoscope to clean the interior of the lumen. In the perfusion device consisting of the above perfusion pump and perfusion port, however, the perfusion pump is simultaneously connected to several perfusion ports. When the perfusion pump delivers the fluid, it is affected by the distraction effect of multiple perfusion ports, greatly reducing the outlet pressure of the perfusion ports. Furthermore, the perfusion pump plays only a role in promoting the circulation of the cleaning fluid. During internal transmission within the lumen, the liquid pressure of the cleaning fluid is continuously reduced with the absorption by the dirt in the lumen. This leads to a gradual weakening of the dirt-promoting effect of the cleaning liquid in the lumen, whereby the cleaning effect at the end of the lumen is significantly reduced. Accordingly, the laparoscopic ultrasonic cleaning machine described above is not yet able to thoroughly clean the interior of the lumen.

Ziel ist es, den Effekt zu erzielen, dass ein einzelnes Rohr verbunden ist, aber die übrigen Rohre geschlossen sind. Daher kann die von der Saugpumpe erzeugte Saugkraft den Einfluss des Ablenkungseffekts vermeiden und vollständig auf die angeschlossene Rohrleitung einwirken, was grundsätzlich die Stabilität des Druckes der Reinigungsflüssigkeit innerhalb des Lumens gewährleistet. Aufgrund der Saugwirkung der Flüssigkeitssaugpumpe am Wasserauslass erhöht sich außerdem die Attraktivität der Reinigungsflüssigkeit, wenn die Reinigungsflüssigkeit in das Lumen eindringt. Der Saugdruck wird jedoch nicht durch die Schmutzabsorption an der Innenwand des Lumens beeinträchtigt, so dass die Stabilität des Drucks der Reinigungsflüssigkeit in dem Lumen verbessert werden kann und der Effekt der Ultraschallreinigung effektiv verbessert werden kann.

Wenn der Dichtungsabschnitt der beweglichen Rolle und der Montageplatte zu dem Katheter rotiert, wird er verwendet, um den Katheter zu schließen; Wenn das Spiel der beweglichen Rolle und die Nut zu dem Katheter rotiert, wird er verwendet, um den Katheter zu verbinden. Durch die oben erwähnte Drehrohrleitung sind der Wasserauslass und der Wassereinlass getrennt verbunden, und das Problem eines großen Flüssigkeitsdruckverlustes in dem Lumen, der durch die Mehrfachrohrverbindung während des Betriebs verursacht wird, wird vermieden. Da außerdem ein Katheter mit dem Auslass verbunden ist, befindet sich der andere Katheter in einem abgedichteten Zustand, so dass der Druck der Flüssigkeit innerhalb der Ultraschallreinigungsmaschine erhöht ist. Somit wird der Flüssigkeitsdruck des Leitungseinlasses verbessert, die Reinigungsflüssigkeit fließt schnell in das Lumen und der Reinigungseffekt davon wird verbessert.
