Avoid rubber stopper particle from entering human body, be conducive to patient health；And when preparing chemotherapeutics, moreover it is possible to a certain degree
Reduction aerosol etc. outlet, avoid Aerosol Pollution air, the pollution environment of chemotherapeutic, ensured medical worker's health.
When using this syringe needle acquisition marrow, the first filter membrane in cartridge filter carries out the filtering of bone slag to marrow, by the
One filter membrane realizes disposable filtering bone slag, simplifies bone marrow collection program, and filter effect is reliable.
Further, it is connected between filter cylinder and triple valve with hose, is also connected to hose between filter cylinder and puncture needle, advantage exists
In structure is simple, folded convenient for receiving.
Further, air bag is fixedly connected between hose and triple valve, connector of the hose close to triple valve side is located at gas
Intracapsular portion, the connector that triple valve is connect with hose also are located inside air bag, and the connector of hose and triple valve is detachably connected, threeway
The first check valve is equipped between valve and hose, the first check valve can unidirectionally be opened by triple valve to hose direction.So set, can
Enter the gas in air bag in hose by extruding gasbag, gas is avoided in drug in hose all push-in infusion bottle
Medicament residue causes to waste in hose.
Further, be equipped with can be by the second one-way valve unidirectionally opened in outside to air bag, second one-way valve and gas for air bag
The second filter membrane for stopping the particle in air is equipped between capsule, so set, mending by second one-way valve into air bag
Gas prevents the impurity in air from entering in air bag by the way that the second filter membrane is arranged.
Further, the medicine bottle puncture needle and the puncture needle of infusion bottle are cased with protection cylinder, and syringe needle is avoided to pollute.
