Abstract
The invention belongs to the technical field of medical apparatus and instruments, and particularly relates to a medical solid-liquid separation aspirator. The medical solid-liquid separation aspirator solves the problems that an existing aspirator is easy to jam and the like. The medical solid-liquid separation aspirator comprises a hollow suction pipe, wherein a suction mouth is arranged at one end of the hollow suction pipe, a tubular body communicated with the suction pipe is arranged at the other end of the hollow suction pipe, a separation cylinder is inserted into the tubular body, one end of the separation cylinder is pressed against the inner side of the end of the tubular body, the other end of the separation cylinder is connected with the tubular body through a detachable structure, a liquid outlet pipe with a liquid outlet communicated with the interior of the separation cylinder is arranged at the end of the separation cylinder, and a solid-liquid separation structure is arranged between the tubular body and the separation cylinder. The medical solid-liquid separation aspirator has the advantages of being reasonable in design, simple in structure, capable of automatically separating solids from liquid through a geometry shape of a multilayer blocking solid, and good in stability, preventing the problem that a pipe cavity is blocked due to the fact that the pipe diameter is limited, preventing attraction objects from reversely flowing, reducing infection risk, needing no repeated disassembling operation, and achieving an illumination function.
Description
Technical field
The invention belongs to technical field of medical instruments, especially relate to a kind of medical solid-liquid and divide
From aspirator.
Background technology
At present, when needing suction areas hydrops, hematocele and cyst clinically, it is generally required to
Relying on suction catheter to complete, traditional suction catheter also exists inconvenience: traditional attraction
Pipe is operationally that solid, liquid attracts simultaneously, is easily caused tube chamber to block up owing to limiting by caliber
Plug；Solid stopping state, pole operationally can not be found in time due to traditional suction catheter
Easily cause attraction reflux, increase infection risk；Due to traditional suction catheter operationally
Produced solid blocking, could process after needing dismounting, can increase the work of medical worker
Measure；Due to repeatedly blocking will disassembling section repeatedly, therefore make operating time extend, unfavorable
In Rehabilitation.
In order to solve the problem that prior art exists, people have carried out long-term exploration, have carried
Go out solution miscellaneous.Such as, Chinese patent literature discloses a kind of operation
Room with Single-use drainage tube [application number: 201420085692.X], including attract hard tube and
Attracting flexible pipe, attract the bottom of hard tube to be tightly connected with attracting flexible pipe, described attraction is hard
The middle part of pipe is provided with connector, and the attraction hard tube above connector has suction hole,
Hard tube is attracted to be tightly connected with attracting cover by connector, the latter half interior that attraction is covered
Footpath is the twice attracting hard tube external diameter, attracts internal diameter and the attraction hard tube of the top half of cover
Internal diameter identical, its top is suction port.Such scheme to some extent solves existing
There is suction catheter to cannot be carried out the problem that solid-liquid separates, but the program still also exist:
Blocking-proof result is poor, during blocking will disassembling section repeatedly, therefore make the problem that operating time extends.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of reasonable in design, solid-liquid divides
From effective medical solid-liquid separation aspirator.
For reaching above-mentioned purpose, present invention employs following technical proposal: this medical solid-liquid
Separate aspirator, including the suction pipe in hollow, it is characterised in that described suction pipe
One end is provided with suction port, and the other end is provided with the cylindrical body being connected with suction pipe, described
It is inserted with separable cartridge in cylindrical body, and described separable cartridge one end is against being arranged on cylinder
Shape body tip inside, the other end is connected with cylindrical body by dismountable structure, and described divides
The drain pipe of the liquid outlet having and be connected inside separable cartridge it is provided with from barrel end,
Be provided with between cylindrical body with separable cartridge can by liquid radial conduction to cylindrical body with separate
Between cylinder and the solid-liquid that is back in drain pipe and solid can be intercepted in separable cartridge
