Axial forward end, rear end in contact, sealing be cooperatively connected.
The wall thickness of the flexible steel in flat section tubing is less than the wall thickness of suction aspirator tip and transition connector.
The sucker includes intermediate sucker, intermediate sucker periphery be equipped with multiple uniformly distributed side suckers, the intermediate sucker,
The diameter of side sucker is less than the aperture of outlet end.
Operation with vacuum extractor using medical PVC, PE perhaps PP material be made flexible steel in flat section tubing using PVC, PE or
PP thin-walled stretches hose and is made.
The preferable effect of the utility model is:
1. the utility model is performed the operation when medical assistant's oriented manipulation chamber back side, Novel vacuum suction device head is bent to predetermined angular
It takes and is placed in operating cavity, not only can ensure that the function of aspirator smoking, but also surgical procedure will not be blocked, smog when can reduce operation
Sucking and barrier blood spluttering, clear surgical field of view, guarantee operation be normally carried out.
2. the utility model is compact-sized, it is convenient to hold, and sealing plate is equipped with intermediate sucker, is equipped in intermediate sucker periphery
Multiple uniformly distributed side suckers.Smoking great efforts, can increase the area of barrier blood, and suction aspirator tip can flexibly overturn, perform the operation
Random conversion angle in operating cavity with larger area draw blood and its hetero-organization liquid and can obstruct outside the blood of blood vessel
It splashes, the effective occupational exposure for reducing medical staff and clear surgical field of view guarantee being normally carried out for operation, safeguard medical staff
Health.
3. operation is made with vacuum extractor of medical PVC, PE PP material, flexible steel in flat section tubing using PVC, PE or
Person's PP thin-walled stretches hose and is made.It is disposable, the problems such as reusing and causing pollution in art, infection is avoided, by
It is less than the wall thickness of suction aspirator tip and transition connector in the wall thickness of flexible steel in flat section tubing, stretching tube can arbitrarily bend, conversion angle, together
Shi Qiangdu meets requirement.
4. the front end of aspirator tube is equipped with chamfering, can aspirator tube be inserted into connecting tube and be connected convenient and strength-savingly
The sealing cooperation of adapter tube inner wall of the pipe.
5. since transition connector is the curved-surface structure in axial medium position evagination, the outer circle and curved surface knot of aspirator tube
The axial forward end of structure, rear end in contact, sealing are cooperatively connected, and transition connector contacts close reliable, good airproof performance with aspirator tube,
Guarantee assimilation effect.
