Description

Efficient suction aspirator tip

This utility model belongs to medical apparatus and instruments, is the improvement to the medical suction aspirator tip structure of using in the operation.

Present medical suction aspirator tip is used comparatively extensive clinically, but still has still unsolved shortcoming and problem so far.Be better to expose the art open country in the operation, need at any time liquid sucking-off the art Yezhong.In the absorption process, because surrounding soft tissue is adsorbed in suction aspirator tip, blocks and inhale the hole, influence normal continuous absorption of liquid, thereby cause incuring loss through delay operating time.Figure one, figure two and figure three are prior art structural representations.Figure one is the two bushing type suction aspirator tips of metal.The suction aspirator tip of this structure because outer tube does not have passage, can not communicate shell clearance with the external world, thereby makes the head of suction aspirator tip produce negative pressure, is easy to make sieve aperture 2 and inner orifice to be blocked absorption by soft tissue, makes operation be difficult to normally carry out.Figure two and figure three are disposable suction aspirator tip, and figure two does not have interior pipe, and do not have passage and communicate with the external world, and during use, the head of suction aspirator tip produces negative pressure, are easy to make imbibing hole (sieve aperture) to be blocked by soft tissue absorption.Though the structure of figure three has and the extraneous passage that communicates, but because interior pipe is not set, and head has only an imbibing hole, when inhaling the hole when getting clogged, even communicate with outside air, eliminated negative pressure, but, imbibition has been interrupted owing to stopped absorption liquid, the liquid one-time continuous can not be absorbed, and the speed of absorbing liquid is very slow, use just pretty troublesome, normally the carrying out of influence operation.

The purpose of this utility model is to overcome the shortcoming that exists in the said structure, and a kind of efficient suction aspirator tip is provided.

The purpose of this utility model is to realize like this.A kind of efficient suction aspirator tip of metal structure and the efficient suction aspirator tip of two kinds of disposable plastic structures are provided.The efficient suction aspirator tip of metal structure, interior pipe 4 afterbodys fixedly are communicated with union joint 7; Interior pipe afterbody is with hold-doun nut 6, and nut is spacing with a stop collar 11; The nut end is threaded, and is threaded with outer tube 3; Outer tube head has sieve aperture 2, and the outer tube afterbody has passage 5; The outer tube cephalic par flashboard 1 that is threaded; The flashboard threaded portion has the lock hole, and interior tube head inserts in the lock hole; Interior tube head has side opening 8.

Operation principle is, when interior pipe side opening 8 was rotated to flashboard 1, the flashboard body was closed side opening, kept suction aspirator tip in original technology directly to absorb the function of liquid, and applicable Rhizoma Atractylodis Macrocephalae is wild shallow or expose good lacuna imbibition function.When interior pipe side opening was rotated to the position in flashboard lock hole, side opening was open, and when interior tube head was obstructed, side opening began imbibition.At this moment wild dark the reaching of applicable Rhizoma Atractylodis Macrocephalae exposes bad lacuna imbibition.To organize because of bilayer sleeve and to hinder outside outer tube wall, pipe 3 in soft tissue can not arrive, and shell clearance communicates with the external world, makes shell clearance and extraneous equipressure; When in liquid flows into, managing side opening, gas is extruded, produced negative pressure the liquid sucking-off.When the shell clearance no liquid, gas promptly is full of shell clearance, has eliminated the local decompression that produces owing to lasting attraction, and has made the unlikely suction aspirator tip that is adsorbed in of surrounding soft tissue.Owing to the eddy current that local gas is arranged produces siphonage, the liquid in the surrounding tissue gap is continued to flow to suction pump.This suction aspirator tip can be mobile with being intended in the interstice, thereby reach the purpose of once thoroughly absorbing liquid continuously.

The suction aspirator tip of this structure, by adopting shell clearance to communicate in the external world, eliminate the principle of local decompression, and internally pipe 3 improvement of setting up little flashboard, and make suction aspirator tip can keep the function of former suction aspirator tip, increased again in the art open country and absorbed function continuously with the bad lacuna liquid of exposure deeply, utilized the improved form of this principle, can be made into the syringe pipe of various lacunas.

The disposable efficient suction aspirator tip of two kinds of plastics is provided.A kind of structure is to have outer tube 3 and interior pipe 4, and outer tube head has sieve aperture 2, and interior pipe 4 is connected to one with union joint 7; On outer tube, have passage 5, ventilation pore area one gag 9; Union joint and outer tube 3 insert and are tightly connected; Interior tube head has side opening 8.Another kind of structure is that the union joint middle part has passage 10 and gag 9, and the passage 5 on the outer tube can not be with other structures of gag the same.Operation principle is the same with the suction aspirator tip operation principle of metal structure.
