Abstract
The utility model relates to an aspirator head for medicine. The utility model mainly comprises a mouthpiece, a handle tube, a suction tube and an end, wherein, the external shape of the suction tube appears like the sections of three straight tubes which can form a certain angle respectively; the shape of the channel in the suction tube is an arc shape. The utility model can adopt plastic materials and the components of the utility model can be used as a whole body and can be formed in once moulding, being a one-off and bend-typed aspirator head; being clean and convenient, the utility model can suck out the foreign matter behind the internal organs effectively.
Description
This utility model relates to a kind of medical suction aspirator tip, particularly a kind of bending-type suction aspirator tip, and it belongs to technical field of medical instruments.
In clinical operation, usually need foreign body (for example blood stains) sucking-off external inside of human body, this is normally finished by suction pump, domestic known suction aspirator tip generally all is the metal suction aspirator tip that uses repeatedly at present, this suction aspirator tip is owing to adopting metal material ice-cold hard feeling that ten minutes feels bad with making patient during human organ contact because of what attract head, and, be exactly cleaning up of suction aspirator tip strictness a pretty troublesome time-consuming job therefore owing to will use repeatedly.No. 92213426 Chinese utility application records be a kind of disposable overall plastic suction aspirator tip, though this suction aspirator tip has solved the existing problem of above-mentioned metal suction aspirator tip, but, use need be the time very inconvenient the foreign body sucking-off of human organ back because this suction aspirator tip and above-mentioned suction aspirator tip all are straight pipe types.For addressing this problem, a kind of disposable overall plastic suction aspirator tip is abroad arranged, its profile is crooked, for sucking-off foreign body more fully, this suction aspirator tip stretches into intravital suction pipe and is made up of three straight-tube portions that are mutually certain angle, though the more convenient back sucking-off foreign body that reaches intracorporeal organ more fully of the suction pipe of this profile, but be mutually certain angle by three straight tubes, so just increased foreign body mobile resistance in pipe greatly, thereby will increase the power of suction pump greatly, so not only power consumption is big but also noise that increase because of increase power also can produce harmful effect to doctor and the patient in the operation.
The purpose of this utility model just provides a kind of novel medical suction aspirator tip, and it is the foreign body of sucking-off intracorporeal organ back very fully not only, but also can reduce foreign body mobile resistance in suction pipe.
Technical solutions of the utility model to the effect that, its suction aspirator tip is by mouthpiece, handle tube, tube segment and termination are formed, wherein, the appearance of suction pipe has three straight-tube portions at an angle to each other, it is characterized in that suction pipe interior conduit be shaped as arc.Suction aspirator tip of the present utility model preferably adopts plastic material and the suction aspirator tip each part mentioned above is done as a whole, once molding formed.
Since the interior conduit of the suction pipe of suction aspirator tip of the present utility model be shaped as arc, so just reduced the resistance of foreign body in vivo in suction pipe greatly, that is: reduced the loss of flood peak, thereby make suction pump need not the very big just foreign body of sucking-off intracorporeal organ back fully of power consumption, and owing to can all adopt the plastic material manufacturing, cost is low, can become disposable suction aspirator tip, thereby has saved the trouble of cleaning.
Below in conjunction with accompanying drawing, this utility model is described in detail in the mode of embodiment.
Fig. 1 is the sketch map of an embodiment suction aspirator tip of this utility model;
Fig. 2 is the sectional view along the B-B of Fig. 1;
Fig. 3 is another embodiment sketch map of the handle tube of this utility model suction aspirator tip;
With reference now to Fig. 1 and Fig. 2, first embodiment of the present utility model is described.In Fig. 1, suction aspirator tip is by mouthpiece 1, handle tube 2, suction pipe 13 and termination 6 are formed, wherein the diameter of the interior conduit 10 of mouthpiece 1 is greater than the diameter of the interior conduit 11 of handle tube 2, and mouthpiece 1 is connected on handle tube 2 afterbodys, and mouthpiece links to each other with suction pump by a succession of parts in use.Handle tube 2 has a diameter (arrow direction among the figure) diminishing truncated cone-shaped outer surface (its cross section as shown in Figure 2) forward, on the close position of handle tube 2 front ends, on handle tube 2 outer surfaces, three recesses 7 are arranged with two sides, some are arranged perpendicular to handle tube (horizontal little fin of longitudinal axes L or little groove in recess 7, in use, people's thumb, ten fingers and middle finger are pinched respectively on these three recesses, and a recess 8 is also being arranged near the afterbody of handle tube 2, during use, the tiger of hands leans against on the recess 8 when people's finger pinches recess 7.Because the outer surface at handle tube 2 has recess 7 and 8, in use, people's finger is pinched on these recesses just can arrest suction aspirator tip very quietly in the anxiety operation.
Joining of handle tube 2 with suction pipe 13, suction pipe 13 is rendered as three straight-tube portions 3,4 and 5, the outer surface of straight-tube portion 3 is diameter (arrow direction among the figure) diminishing truncated cone-shaped forward, and its afterbody and handle tube 2 join, and front end links to each other with straight-tube portion 4, the outer surface of straight-tube portion 4 is cylindrical, the outer surface of straight-tube portion 5 also is cylindrical, and its afterbody and straight-tube portion 4 join, and front end and termination 6 join.The angle of the axis of the axis of straight-tube portion 3 and straight-tube portion 4 should be less than the angle of the axis of the axis of straight-tube portion 4 and straight-tube portion 5, the shape of the internal channel 12 of suction pipe 13 is shape, angle between straight-tube portion 3 and the straight-tube portion 5 is at 115 °--between 180 °, be preferably 120 °-130 °, interior 12 diameter of the diameter of the internal channel 11 of handle tube 2 and suction pipe is identical.
The termination 6 of suction aspirator tip is an annular boss, and its overall diameter has at least one through hole 9 greater than the overall diameter of the straight-tube portion 5 of suction pipe 13 on the circumferential surface of boss, be preferably 4, the length of through hole 9 is 2.5mm-3.0mm, is preferably 3mm, wide is 1.5mm-2, and 5mm is preferably 2.5mm.
Fig. 3 is the handle tube sketch map of another embodiment of this utility model suction aspirator tip, wherein, on position, an annular groove 15 is arranged, the handle tube of being parallel to 2 longitudinal axis fin or grooves are arranged in groove 15, a groove 14 is also arranged at afterbody near handle tube 2 near the front end of handle tube 2.Like this, just can arrest suction aspirator tip in any direction securely during use.
Characteristics of the present utility model and advantage below have been described by way of example; obviously; in protection domain of the present utility model, various changes and improvements can also be arranged; for example the through hole 9 of termination 6 also can be circle; radius is 1.5mm--2.5mm, and this all should be subjected to protection of the present utility model.
