Abstract

The utility model provides a suction tube for a nose and belongs to the field of medical flushing instruments. The suction tube for the nose comprises a flat-column-shaped tube body, wherein screening holes are densely distributed on a tube wall of a front section of the tube body, and the front end of the tube body is in a shape of a smooth circular arc. The suction tube for the nose can be conveniently stretched into the nasal passage, inner mucosal injury of the nasal cavity is not caused, a medicine spraying range is wide, medicine absorption is facilitated, meanwhile hematocele in the nasal cavity can be quickly removed, an occupied space is small, and surgical operation is facilitated.

Description

The nose suction pipe

Technical field

This utility model relates to a kind of Medical Irrigator tool, is specifically related to a kind of nose suction pipe.

Background technology

When nasal cavity inflammation is given prominence to, therefore concha nasalis is and during enlargement, columned custom is usually because can't must shrink concha nasalis inferior earlier by meatus nasi communis smoothly or can't arrive the middle nasal meatus smoothly and the necessary middle nasal concha that shrinks earlier, this sprays vasoconstrictor or topical anesthetic can cause certain difficulty for needs at nasal cavity, and spray medicine scope is often inhomogeneous, and medicine is the difficult lateral wall of nasal cavity that needs most sprinkling that concentrates on also.

The suction pipe of single hole cylindrical design, because cross-sectional area is bigger, especially transverse diameter is bigger, causes the damage of nasal cavity mucosa when suction pipe is advanced to the nasal cavity rear end easily, particularly when the nasal cavity inflammation more serious, the easier generation of damage when the obvious or myxedema of concha nasalis enlargement is obvious.

Simultaneously; in nasal endoscopic surgery; usually can run into art district oozing of blood; because the used nasal cavity suction pipe overwhelming majority is that single round hole is cylindric at present; this will seek medical advice to give birth to must one to hand and hold conchoscope; the another hands then must be picked up suck blood Cao lock of suction pipe repeatedly, has so just wasted a large amount of operating times.Because columned suction pipe itself has certain diameter, and conchoscope also has certain diameter, both stacks just need bigger space to allow operation, but the nasal endoscope operation of extensively carrying out in the world wide at present mainly still concentrates on the middle nasal meatus zone, and middle nasal meatus itself is a relative narrow space, if operating forceps or the scalpel that nasal endoscopic surgery is used always, can seem very crowded of middle nasal meatus zone then, cross apparatus not only bad for operation technique, and can allow the doctor in a rush.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of nose suction pipe of entering nasal meatus, can not causing nasal cavity mucosa injury and effect of spraying pesticide and suck blood effective be convenient to.

The technical scheme that this utility model solves the problems of the technologies described above is:

A kind of nose suction pipe comprises body, and this body is flat column, is densely covered with sieve aperture on the tube wall of the leading portion of this body, and the front end of this body is smooth circular arc.

A preferred version of the present utility model, wherein, sieve aperture is the angling hole of outlet towards the place ahead.The sieve aperture of inclination is set, is conducive to medicinal liquid is sprayed forward, prevent that medicinal liquid from flowing backwards.

A preferred version of the present utility model, the internal diameter of its middle tube body reduces from the back segment to the leading portion gradually.Adopt the purpose of this scheme to be, reduce making the volume of inner chamber from the back segment to the leading portion, reduce gradually from back segment to the leading portion internal diameter gradually, thereby increase the pressure that is expelled to the medicinal liquid in the cavity, more be conducive to fluid and be sprayed onto nasal cavity.

A preferred version of the present utility model wherein, also is provided with sieve aperture in the front end of body.Adopt the purpose of this technical scheme to be, make medicinal liquid also can from the front end of body, spray, enlarge spray medicine scope.

A preferred version of the present utility model, wherein, the rear end of body is provided with bending segment, and the end of this bending segment is provided with the joint that is complementary with syringe.Adopt the purpose of this technical scheme to be, make this suction pipe be convenient to be connected handled easily with syringe; Especially, the angle between the axis of the axis of bending segment and body is 90 °.

A preferred version of the present utility model, wherein, the cross section of sieve aperture is circular.

A preferred version of the present utility model, wherein, sieve aperture is divided into many groups, and each group comprises a plurality of sieve apertures that are looped around on the tube wall, organizes sieve aperture along the length direction distribution of the leading portion of body more.

This utility model compared with prior art has following beneficial effect:

1, because nose of the present utility model is flat column with the body of suction pipe, and this shape and nasal meatus shape adapt, it is interior and can not cause damage to mucosa in the nasal meatus to be convenient to enter smoothly nasal meatus;

2, because the leading portion of body is smooth circular arc, so mucosa in the nasal meatus can not stabbed in the end of insertion process middle tube body;

3, because the leading portion of body is densely covered with sieve aperture, therefore not only can realizes wider spray medicine, but also medicine can be sent in lateral wall of nasal cavity in the concentrated area more; Because spray medicine scope is wide, can impel more medicinal liquid by nasal cavity, nasal sinuses mucosa absorption, helps better to bring into play the effect of medicine;

4, because the leading portion of body is densely covered with sieve aperture, when therefore being used for drawing the hematocele of nasal cavity, increased the contact area with blood, be convenient to absorb more quickly the nasal cavity hematocele; And can continue to suck blood and do not take the more space of nasal cavity, be convenient to operation technique, be applicable to nasal endoscope operation, nasal septum surgery, concha nasalis operation etc.
