Description

Suction tube

Technical Field

The utility model relates to the technical field of instruments, in particular to a suction tube.

Background

The suction tube, as a surgical instrument, is used in various departments to draw out or discharge the liquid or fluid to be discharged from the body by negative pressure, so as to achieve the purpose of treatment.

The existing suction tube generally comprises a handle and a suction tube body, wherein the suction tube body is a metal tube, the handle and the suction tube of the suction tube are in a fixed structure and are inconvenient to use, one handle is provided with one suction tube, and the cost of a disposable appliance is too high, so that the improvement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the technical defect who exists among the prior art, and provide the split type structure that facilitates use attract the pipe, realize that the handle can repetitious usage, and attract the pipe disect insertion handle in fixed can, and the convenience is using the completion back, will attract the pipe to pull down the processing.

For realizing the utility model discloses a technical scheme that the purpose adopted is:

the utility model provides a attract pipe, including attract pipe and with attract pipe complex handle, the outward appearance of handle forms a plurality of axial arrangement's even recess in order to realize anti-skidding function, be hollow structure in the handle for attract the pipe to stretch into the back from the other end from one end, connecting pipe of one end threaded connection of handle, but axial displacement's surface is the locking plate of inclined plane structure is installed through the mounting hole that forms on the surface on the connecting pipe, the nearly upper end in side of locking plate forms the boss, the boss is connected with an annular ring, the annular ring snare is in outside the connecting pipe.

Two of the locking plates are symmetrically arranged on the connecting pipe.

The outer wall of one end of the suction tube is provided with a plurality of drainage holes.

The utility model discloses attract the pipe, through connecting pipe of one end threaded connection of handle, but install axial displacement's surface for the locking plate of inclined plane structure through the mounting hole that forms on the surface on the connecting pipe, the nearly upper end in side of locking plate forms the boss, the boss is connected with an annular ring, annular ring cover is in outside the connecting pipe, can realize like this will attract pipe locking in the connecting pipe, realize when utilizing the handle operation, realize the fixed to the attraction pipe, prevent to slide the influence operation.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-4, the utility model relates to a suction tube, which comprises a suction tube 6 and a handle 1 matched with the suction tube, wherein the outer shape of the handle forms a plurality of axially arranged uniform grooves 21 to realize the anti-skid function, the handle is internally provided with a hollow structure for the suction tube 6 to extend from one end and the other end, as shown in fig. 1, the other end 61 of the suction tube extends from the tube body 4 at the rear end of the handle, the tube body 4 and the handle 1 are of an integrated plastic structure, a baffle edge 3 is formed in the middle, the handle is operated and used in the direction, wherein one end of the handle is connected with a connecting tube 5 through a thread structure 11, a locking plate 9 which can axially move and has an inclined plane structure 91 as the outer surface is arranged on the connecting tube through a mounting hole 10 formed on the surface, a boss 92 is formed on the side surface of the locking plate near the upper end, and is connected with an annular ring 8, the ring-shaped ring is sheathed outside the connecting tube 5.

The connecting pipe 5 is provided with an internal thread, the handle 1 is provided with an external thread structure, so that the threaded connection and fixation between the connecting pipe and the handle are realized, and the assembly, the disassembly, the installation and the like are convenient.

The connecting pipe 5 may be a plastic pipe, and the surface thereof has a certain roughness so as to increase friction force after contacting the annular ring made of plastic material.

Wherein, the handle is made of hard plastics.

The locking plates are made of elastic plastics, and the two locking plates are symmetrically arranged on the connecting pipe.

Elastic material the locking plate after being pushed into the clearance between connecting pipe and attraction pipe by external force, receive extrusion deformation, through the deformation of plastic, deformation and will attract the pipe tightly with frictional force embrace, simultaneously, the up end of boss can be the state of keeping level with the surface of connecting pipe, can make the internal surface that encircles 8 that also makes by elastic plastic compress tightly the contact mutually with the surface of connecting pipe like this, makes and has the space 12 disappearance between original annular circle and the connecting pipe, can realize like this with the locking plate is fixed motionless to guaranteed to attract the pipe and not displaced when the operation, in order to guarantee the normal clear of operation.

Wherein, a plurality of drainage holes 7 are formed on the outer wall of one end of the suction tube, so as to suck the sucked substances, and discharge the sucked substances after being led out from the suction tube.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
