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 needle-free joint microbial invasion tester. A test sample container equipped with a test needle-free joint is conveyed to a conveying rotary plate through a conveying assembly, and is transported to a rotary locking device driven by a rotary conveyer belt of the conveying rotary plate, when a lock type Luer taper external taper joint of an injector is over against a test needle-free joint at the upper end of the test sample container, the rotary locking device rises spirally to complete screwing-in and lock of the test needle-free joint to the lock type Luer taper external taper joint, reciprocating slight swing of a swing mechanism is utilized to drive the bidirectional reciprocating rotation of a bidirectional rotation gear within certain angle, and further drives continuous liquid pumping and injection operations of an injection handle. Therefore, the needle-free joint microbial invasion tester realizes mechanization of nearly one hundred test cycles repeated in the microbial invasion test of a liquid channel and blood channel joint, forms an integrated intelligent experimental line, reduces heavy manual operation and pollution in existing microbial invasion test, also improves the efficiency of the microbial invasion test, and ensures the accuracy of 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 ...
