Description

A kind of expander

Technical Field

The utility model belongs to the field of medical equipment, in particular to expander.

Background

At present, the known dilator is composed of an upper dilator and a lower dilator, and self-secretion is generated in the vaginal cavity of a patient during the diagnosis and treatment process of a clinician. Most of the existing disposable vaginal dilators are medical instruments without an illumination light source and a visual image technology, and due to the unreasonable design, the secretion of the vaginal cavity of a patient is difficult to remove in time, so that the diagnosis visual field of a clinician is influenced, great inconvenience is brought to the examination and diagnosis of the clinician, and the operation is easy to cause accidents.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a dilator is provided, set up initiative imbibition passageway and imbibition hole in the dilator to can be fast effectual with the secretion absorption of the lower page or leaf week side of dilator.

The utility model discloses a realize like this, provide an expander, including last expansion piece, lower expansion piece, go up expansion piece rear end and expansion piece rear end down articulated, the outside periphery of expansion piece front end upside is equipped with a plurality of equipartitions and imbibition hole up down, and this internal imbibition passageway that is equipped with of expansion piece down, each imbibition hole imbibition passageway intercommunication respectively, and the articulated one end of expansion piece is equipped with the pipette down outward, and the lower extreme of this pipette is connected with quick-operation joint, and its upper end and the body of expansion piece down link up to the imbibition passageway.

Furthermore, the outer peripheral edge of the upper side of the lower expansion sheet is provided with an upwardly extending opening edge, and the opening of each liquid suction hole is lower than the opening edge.

Furthermore, an annular liquid collecting groove is formed in the inner side of the opening edge, and liquid sucking holes are uniformly distributed in the annular liquid collecting groove.

Furthermore, an isolation separation blade is arranged outside the hinged position of the rear end of the lower expansion blade, a drainage channel from top to bottom is arranged in the isolation separation blade, the upper end of the drainage channel is communicated and connected with a liquid suction channel, and the liquid suction tube is communicated and connected with the lower end of the drainage channel through the upper end.

Compared with the prior art, the utility model relates to an expander, through being equipped with a plurality of equipartition and up imbibition holes in the periphery of the front end upper side of lower expansion piece, pipette one end is connected with imbibition passageway intercommunication that lower expansion piece was established, its other end passes through quick-operation joint and is connected with imbibition equipment, thus when using the expander, secretion on the lower expansion piece week side vaginal wall that main secretion is gathered can be fast, effectual absorbed, thus clinician can be more clear look over the histopathology condition of vaginal wall;

the dilator is a disposable medical product, one end of the liquid suction pipe is connected with the quick joint, on one hand, the liquid suction equipment can be repeatedly sterilized and used, but diagnosis and treatment are not influenced, and on the other hand, the dilator serving as a main human body contact part can be replaced and used;

the periphery of the upper side of the lower expansion sheet is provided with an upwardly extending opening edge, so that discomfort caused by direct absorption of the liquid absorption hole on the vaginal wall of a patient is avoided;

the inner side of the opening edge is provided with an annular liquid collecting groove, all liquid sucking holes are uniformly distributed in the annular liquid collecting groove, and the secretion is concentrated in the annular liquid collecting groove, and then all the liquid sucking holes are used for sucking and removing.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example (b): referring to fig. 1-5, an expander comprises an upper expanding sheet 1 and a lower expanding sheet 2, wherein the rear end of the upper expanding sheet 1 is hinged with the rear end of the lower expanding sheet 2, the periphery of the upper side of the front end of the lower expanding sheet 2 is provided with a plurality of liquid suction holes 21 which are uniformly distributed and face upwards, a liquid suction channel 22 is arranged in a body of the lower expanding sheet 2, each liquid suction hole 21 is communicated with the liquid suction channel 22, a liquid suction pipe 3 is arranged outside the hinged end of the lower expanding sheet 2, the lower end of the liquid suction pipe 3 is connected with a quick connector 31, and the upper end of the liquid suction pipe and the body of the lower expanding sheet 2 are. The peripheral edge of the upper side of the lower expansion sheet 2 is provided with an upwardly extending opening edge 23, and the opening of each liquid suction hole 21 is lower than the opening edge 23. An annular liquid collecting groove 24 is arranged on the inner side of the opening edge 23, and the liquid sucking holes 21 are uniformly distributed in the annular liquid collecting groove 24. An isolation separation blade 25 is arranged outside the hinged position of the rear end of the lower expansion blade 2, a drainage channel 26 from top to bottom is arranged in the isolation separation blade 25, the upper end of the drainage channel 26 is communicated and connected with the liquid suction channel 22, and the upper end of the liquid suction tube 3 is communicated and connected with the lower end of the drainage channel 26.

Wherein lower expansion piece adopts a plurality of moulds heat-seal assembly to form to thereby be convenient for mould shaping processing to form imbibition hole 21, pore such as imbibition passageway 22, for example annular catch basin 24 and the imbibition hole 21 of bottom thereof, can mould the piece through the fashioned annular catch basin alone, and form the imbibition hole 21 of equipartition simultaneously at this mould shaping, then form open imbibition passageway 22, oral edge 23 at the front end edge of lower expansion piece 2 through mould shaping, then mould the piece heat-seal in open imbibition passageway 22 with annular catch basin, thereby form the structural feature that imbibition hole 21 and imbibition passageway 22 communicate. And so on, the holes and channels in the lower expansion sheet 2 are formed.

It is to be understood that: although the present embodiment has been described in more detail, these descriptions are only simple descriptions of the present invention, but not limitations of the present invention, and any creation of the present invention that does not exceed the spirit of the present invention all falls into the protection scope of the present invention.
