Abstract
The utility model relates to a joint lavage drainage apparatus which comprises a drainage rod and a drainage sleeve pipe, wherein the drainage sleeve pipe is movably arranged outside the drainage rod in a sleeved mode. A drainage channel where fluid can flow through is arranged between the drainage rod and the drainage sleeve pipe, a filter net which can extend out or retract back relative to the drainage sleeve pipe is arranged at the front end of the drainage rod, after the filter net extends out of the drainage sleeve pipe, the filter net is open in a hollow shape and covers an inlet in the front end of the drainage channel, and a handle is arranged at the tail end of the drainage rod and enables the drainage rod to move relative to the drainage sleeve pipe. When lavage drainage is needed, the filter net extends out of the drainage sleeve pipe and is open to cover the inlet in the front end of the drainage channel, joint fluid can enter the hollow part of the filter net from the filter net and then flow away through the drainage channel, due to the filter net which is open in the hollow shape, broad buds or internal organization in a joint can not block the drainage channel easily, the filter net retracts into the drainage sleeve pipe after drainage, and medical staff can use the apparatus conveniently. The joint lavage drainage apparatus is applied to joint lavage drainage.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of joint lavage and drainage device.
Background technology
In prior art, rheumatism, as the hydrarthrosis that rheumatoid arthritis, ankylosing spondylitis, osteoarthritis and gouty arthritis etc. occur, can cause human synovial to swell and ache, the ill symptoms of limitation of activity.At present, for this type of patient, generally adopt syringe to be rinsed and hydrarthrosis is extracted out by syringe, but this mode not only operates inconvenience, also can make flushing not thorough, curative effect is difficult to reach expection.
The utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is to provide a kind of easy to operate joint lavage and drainage device.
The technical scheme that this utility model adopts is:
A kind of joint lavage and drainage device, comprise drainage bar and the movable set drainage casing tube outside drainage bar, there is the drainage channel flow through for liquid between described drainage bar and drainage casing tube, the front end of described drainage bar is provided with the filter screen that drainage casing tube stretches out or retracts relatively, described filter screen stretches out from drainage casing tube the front end inlet that back brace is split into hollow shape and is covered in drainage channel, and the tail end of described drainage bar is provided with the handle that drainage bar is moved relative to drainage casing tube.
As further improvement in the technical proposal, described filter screen struts rear formation spheroid.
As further improvement in the technical proposal, the outer cover of described drainage bar afterbody is provided with guide post, and described guide post is provided with axial arranged gathering sill, and described taper knob is located at the guide post outside and is provided with the part be connected with the drainage bar tail end in gathering sill.
As further improvement in the technical proposal, the longitudinal cross-section of described handle is " work " font.
As further improvement in the technical proposal, the tail end of described drainage casing tube is provided with gripping handle, and described guide post is inserted in gripping handle.
As further improvement in the technical proposal, described gripping handle surface is provided with anti-slip veins.
The beneficial effects of the utility model are: when the needs lavage and drainage, filter screen is stretched out to drainage casing tube and struts, make it to cover the front end inlet of drainage channel, joint fluid can enter its hollow parts from filter screen and flow away from drainage channel, because strutting into the filter screen of hollow shape exists, IA granulation or interior tissue are not easy to stop up drainage channel, and in the drainage casing tube of after drain, filter screen being retracted, medical personnel are very easy to use.
The accompanying drawing explanation
Below in conjunction with drawings and embodiments, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this utility model using state schematic diagram;
Fig. 3 is the schematic diagram of this utility model drainage casing tube.
The specific embodiment
A kind of joint lavage and drainage device, comprise drainage bar 1 and the movable set drainage casing tube 2 outside drainage bar 1.Have the drainage channel flow through for liquid between drainage bar 1 and drainage casing tube 2, the front end of drainage bar 1 is provided with a filter screen 3, and the tail end of drainage bar 1 is provided with one handle 4.Drive drainage bar 1 by operating grip 4 and move around vertically in drainage casing tube 2, make filter screen 3 stretch out or retract from the opening part of drainage casing tube 2 front ends.As shown in Figure 1, the state of drainage bar 1 is for being retracted in drainage casing tube 2; As shown in Figure 2, drainage bar 1 struts into hollow spherically from stretching out in drainage casing tube 2, and is covered in the front end inlet place of drainage channel, makes joint fluid all flow into from the aperture of filter screen 3, prevents that IA granulation or interior tissue from stopping up drainage channel.
The outer cover of drainage bar 1 afterbody is provided with guide post 5, drainage bar 1 in the axially movable while of drainage casing tube 2 also in the interior movement of guide post 5.Guide post 5 is provided with the gathering sill 6 of arranging vertically, handle 4 is set in guide post 5 outsides and is provided with the part be connected with drainage bar 1 tail end in gathering sill 6, this part with handle 4 in the slip of guide post 5 outsides and in the interior slip of gathering sill 6, thereby drive moving axially of drainage bar 1.
The longitudinal cross-section of handle 4 is " work " font, its two ends evagination, the recess size of central authorities with become the finger size close, facilitate people's hand operated.
As shown in Figure 3, the tail end of drainage casing tube 2 is provided with gripping handle 7, and guide post 5 is inserted in gripping handle 7.When design, can be fixing with gripping handle 7 after guide post 5 plug-in mountings, can be also movable plug-in mounting.Gripping handle 7 surfaces also are provided with anti-slip veins.
The above be this utility model preferred embodiment, it does not form the restriction to this utility model protection domain.
