Problems solved by technology

With more and more products of needle-free infusion connectors, the workload of inspectors will become more and more heavy
However, in the manual operation test process, it is easy to bring cumbersome operation, and it is easy to cause problems such as introducing artificial pollution and affecting test results. In order to avoid and reduce pollution, it is necessary to use disposable prefilled syringes (about ten yuan each), which leads to test costs. Too high, waste of manpower and time

Embodiment 1

[0037] The present invention is described in detail as follows in conjunction with accompanying drawing:

[0038] A needle-free joint microbial invasion tester, including a test cabinet 1, an operating table 2, a delivery assembly 3, a delivery turntable 5, a rotation locking device 6, a swinging injection device, and an injection system 11. The delivery assembly 3 and the delivery turntable 5 are set On the console 2, the conveying assembly 3 includes a conveying belt, a driving device, and a transmission wheel. The driving device is a DC motor. It is connected with the drive device, and the drive wheel is driven by the drive device to rotate, so that the conveyor belt is rotated, and the conveyor belt is connected to the bottle inlet and the bottle outlet of the needleless joint microbial invasion tester, and the conveyor belt of the conveyor assembly 3 A steam sterilization chamber 4 is installed on it, and the conveying belt is docked with the conveying turntable 5. The ro...

Embodiment 2

[0040] A needle-free joint microbial invasion tester, including a test cabinet 1, an operating table 2, a delivery assembly 3, a delivery turntable 5, a rotation locking device 6, a swinging injection device, and an injection system 11. The delivery assembly 3 and the delivery turntable 5 are set On the console 2, the conveying assembly 3 includes a conveying belt, a driving device and a transmission wheel, the driving device is a motor, and the two driving wheels placed at the front and rear ends of the conveying assembly are connected by the conveying belt, and one of the two driving wheels is connected to the transmission wheel. The driving device is connected by transmission, and the driving device drives the transmission wheel to rotate, so that the conveyor belt rotates. The conveyor belt is connected to the bottle inlet and the bottle outlet of the needleless joint microbial invasion tester, and the conveyor belt of the conveyor assembly 3 A steam sterilization chamber 4...

Abstract

The invention discloses a needleless joint microbial intrusion tester. A test sample container equipped with a needleless joint for testing is transported to a transport turntable through a transport assembly, and is transported to a rotary locking device driven by a rotating conveyor belt of the transport turntable. , when the locking Luer outer conical connector of the injector is facing the test needleless connector on the upper end of the test sample container, the rotating locking device spirals up to complete the screwing and locking of the test needleless connector to the locking Luer outer conical connector, Using the reciprocating micro-swing of the rocking mechanism to drive the two-way reciprocating rotation of the two-way rotating gear within a certain angle drives the continuous pumping and injection operations of the injection handle, realizing the microbial invasion test of the liquid path and blood path needle-free interface. Repeated nearly a hundred times The test cycle is mechanized to form an integrated intelligent test line, which reduces the heavy manual operation and pollution in the existing microbial invasion test, and improves the efficiency of the microbial invasion test to ensure the accuracy of the experimental operation.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a needleless connector microbial invasion tester and a method for using the same. Background technique [0002] With the development of modern medical technology, the clinical application of intravenous indwelling infusion has been popularized. The clinical deficiencies make it possible to use needle-free connection in the infusion connection system to gradually replace the outdated acupuncture connection. Needle-free connection (infusion) technology refers to the method of no longer using steel needles to puncture the heparin cap in the infusion system. The needle-free airtight infusion technology is no longer used in the infusion system. The needle-punched connection is used for connection, and the needle-free infusion connection is changed to a needle-free infusion connection, which can avoid accidental injury during acupuncture, simplify the operation mode, and reduce the ...
