Utility model content
The purpose of this utility model is just to provide a kind of operation negative-pressure aspirator head;The utility model perform the operation medical assistant towardsIt when the operating cavity back side, Novel vacuum suction device head is bent to predetermined angular takes and be placed in operating cavity, both can ensure that aspirator is inhaledThe function of cigarette, and surgical procedure will not be blocked, the sucking and barrier blood spluttering of smog, dynamics of smoking when can reduce operationGreatly, the area of barrier blood is increased, suction aspirator tip can flexibly be overturn, in the intracavitary random conversion angle of surgical procedure, effectivelyThe occupational exposure of medical staff and clear surgical field of view are reduced or remitted, to guarantee being normally carried out for operation, maintenance medical staff's health.
The technical solution adopted by the utility model to solve its technical problems is that:
A kind of operation negative-pressure aspirator head, including suction aspirator tip, aspirator tube, connecting tube, the connecting tube are flexibilityThe outlet end of connecting tube, suction aspirator tip is connect with flexible steel in flat section tubing front, and the front end of flexible steel in flat section tubing rear portion and aspirator tube connectsIt connecing, aspirator tube rear end is connect with negative pressure suction device, and the aperture of the input end of the suction aspirator tip is greater than the aperture of outlet end,The input end is equipped with sealing plate, and sealing plate is equipped with several suckers.
The flexible steel in flat section tubing rear portion is connect with transition connector, and outer diameter and the transition connector inner hole of aspirator tube are matchedIt closes, the outer diameter of aspirator tube is greater than the internal orifice dimension at flexible steel in flat section tubing rear portion.
The front end of aspirator tube is equipped with chamfering.
The transition connector is the curved-surface structure in axial medium position evagination, the outer circle and curved-surface structure of aspirator tubeAxial 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 orPP 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 angularIt 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 operationSucking 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 peripheryMultiple uniformly distributed side suckers.Smoking great efforts, can increase the area of barrier blood, and suction aspirator tip can flexibly overturn, perform the operationRandom conversion angle in operating cavity with larger area draw blood and its hetero-organization liquid and can obstruct outside the blood of blood vesselIt splashes, the effective occupational exposure for reducing medical staff and clear surgical field of view guarantee being normally carried out for operation, safeguard medical staffHealth.
3. operation is made with vacuum extractor of medical PVC, PE PP material, flexible steel in flat section tubing using PVC, PE orPerson'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, byIt 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, togetherShi 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-savinglyThe 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 tubeThe 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.
Embodiment 1
Such as Fig. 1, Fig. 2, shown in Fig. 3, a kind of operation vacuum extractor, including suction aspirator tip 1, aspirator tube 2, connecting tube4, the connecting tube is flexible steel in flat section tubing 43, and the outlet end 15 of suction aspirator tip 1 is connect with flexible steel in flat section tubing front 41, is flexibly connectedPipe rear portion 42 is connect with the front end of aspirator tube 2, and 2 rear end of aspirator tube is connect with negative pressure suction device, the suction aspirator tip 1The aperture of input end 14 is greater than the aperture of outlet end 15.
The flexible steel in flat section tubing rear portion 42 is connect with transition connector 3, in the outer diameter and transition connector 3 of aspirator tube 2Hole cooperation, the outer diameter of aspirator tube 2 are greater than the internal orifice dimension 44 at flexible steel in flat section tubing rear portion 42.The front end of aspirator tube 2 is equipped withAngle 21.
The transition connector 3 is the curved-surface structure 31 in axial medium position evagination, the outer circle and curved surface of aspirator tube 2The axial forward end 33 of structure 31, rear end 32 contact, and sealing is cooperatively connected.
The wall thickness of the flexible steel in flat section tubing 43 is less than the wall thickness of suction aspirator tip 1 and transition connector 3.
Operation is made with vacuum extractor of medical PVC, PE PP material, flexible steel in flat section tubing 43 using PVC, PE orPerson's PP thin-walled stretches hose and is made.Operation is disposable with vacuum extractor, avoids reuse and causes the dirt in artThe problems such as dye, infection, stretch hose pipe can arbitrarily bend, conversion angle, while intensity meets requirement.
