The utility model is used one time, and thereby, the trouble of cleaning is avoided.

Description

Disposable sucktion syringe needle

This utility model relates to a kind of disposable suction aspirator tip, particularly a kind of disposable composite tube type porous suction aspirator tip, and it belongs to technical field of medical instruments.

The domestic suction aspirator tip that is adopted in clinical operation generally has only a pore at present, though a kind of composite tube type porous suction aspirator tip is also arranged, but because this suction aspirator tip is a metal, to use repeatedly, so not only produce the problem of cleaning trouble, the infection of returning various diseases provides a channel.And because the sleeve pipe and the suction pipe of this suction aspirator tip are screw fixed, waste time and energy so dismantle sleeve pipe, very inconvenient in the use of clinical operation.

In view of the existing problem of above existing suction aspirator tip, the purpose of this utility model just provides a kind of disposable composite tube type porous type suction aspirator tip, it can not only save the trouble of cleaning, and has fundamentally removed the route of infection of disease, and dismantle time saving and energy saving.

The technical solution of the utility model is as follows, its disposable composite tube type porous suction aspirator tip comprises handle tube, suction pipe and sleeve pipe, more than one suction hole is arranged on the wherein telescopic sidewall and be enclosed within on the suction pipe, what it is characterized in that said suction aspirator tip employing is plastic material, near the place of an end of set handle tube a protrusion is arranged at said suction pipe, there are one and the corresponding breach of said protrusion in end at the close said handle tube of said sleeve pipe, and said sleeve pipe is fixed on the set suction pipe by the snap-fit of said breach on it and the said protrusion on the said suction pipe.

Because disposable suction aspirator tip of the present utility model is made by plastic material, and the sleeve pipe of suction aspirator tip is to be fixed on its suction pipe by snap-fit, so, not only cost is low for disposable suction aspirator tip of the present utility model, the trouble that does not have cleaning, fundamentally eliminated the approach of disease propagation, and convenient disassembly saves time.

Below with reference to accompanying drawings, advantage of the present utility model and characteristics are further explained in more detail.

Fig. 1 is the sketch map that this utility model is with the suction aspirator tip of porous casing;

Fig. 2 is the sketch map that this utility model does not put the suction aspirator tip of porous casing;

Fig. 3 is the schematic cross-section along Figure 1A-A;

Fig. 4 is the schematic cross-section along Figure 1B-B.

Referring now to Fig. 1, composite tube type porous suction aspirator tip of the present utility model includes handle tube 1, suction pipe 4 and sleeve pipe 5, the suction hole 7 that at least more than one is arranged on the sidewall of sleeve pipe 5, have one at the center of its front end end face and inhale hole 11(referring to Fig. 4), be preferably in the rear end of sleeve pipe 5, promptly the end near handle tube 1 also has a breach 6, with protrusion 3 snap-fit on the suction pipe 4, and sleeve pipe 5 is fixed on the suction pipe 4.Place at handle tube 1 close suction pipe 4 preferably also has a cannelure 2, preferably also has some to be parallel to the little lug, nib or the little groove of its longitudinal axis in cannelure 2, like this so that user is arrested suction aspirator tip more securely.By Fig. 1, it can also be seen that sleeve pipe 5 slightly is longer than suction pipe 4.

Referring now to Fig. 2, in fact Fig. 2 is exactly a kind of common suction aspirator tip except handle tube 1 has cannelure 2, and handle tube 1 has internal channel 8, and suction pipe 4 has internal channel 9.

Below with reference to Fig. 3 and Fig. 4.From Fig. 3 and Fig. 4 as can be seen, the diameter in the suction hole 11 of sleeve pipe 5 end faces is less than the end face pore 10 of suction pipe 4, and in same cross section, promptly there is an annular space in the diameter of sleeve pipe 5 greater than the diameter of suction pipe 4 between sleeve pipe 5 and the suction pipe 4.

When suction aspirator tip with after suction pump links to each other, and after starting suction pump, in suction pipe 4, produce suction, because the diameter of the end face pore 10 of suction pipe 4 is inhaled the diameter in hole 11 greater than the end face of sleeve pipe 5, so produce negative pressure in the annular space between sleeve pipe 5 and suction pipe 4, thereby make the suction hole 7 on sleeve pipe 5 sidewalls produce suction, when foreign body in vivo is inhaled few arriving to a certain degree, take off sleeve pipe 5 from suction pipe 4, only use suction aspirator tip as shown in Figure 2 to attract to get final product.Because suction aspirator tip adopts plastic material to make, its sleeve pipe 5 is to utilize the inherent plasticity of plastic material self, be fixed on the suction pipe 4 by protrusion 3 snap-fit on its breach 6 and the suction pipe 4, so when suction pipe 4 takes off sleeve pipe 5, as long as exert oneself a little to the termination of suction pipe 4 direction, the breach 6 of sleeve pipe 5 and the protrusion 3 of suction pipe 4 are separated, just can pull up sleeve pipe 5, so just tighten to cooperate with the spiral of suction pipe and take off sleeve pipe more time saving and energy savingly than the sleeve pipe of existing metal suction aspirator tip from suction pipe 4.And, so just avoided the trouble of cleaning because suction aspirator tip of the present utility model adopts plastic material to make, and cost is low, can become disposable suction aspirator tip, also fundamentally eliminated because of using the approach of the disease propagation that suction pump brought.

More than just this utility model has been described by way of example, in fact, in scope of the present utility model, many improvement can also have been arranged, as the fit system of sleeve pipe and suction pipe etc., these improvement and change this utility model scope required for protection of all not leaving.
