Description
Technical field
The utility model relates to liquid to detach engineering device technique field, in particular to a kind of rheumatism joint fluid is extracted except hemorrhage
Device.
Background technique
It in the inspection of rheumatism, needs to extract the joint fluid at diseased joints, then carries out laboratory examination, and close
It saves in liquid extraction, it will usually when syringe needle punctures and enters joint, a small amount of blood, this hemorrhage meeting can be stockpiled in the cavity of syringe needle
Checking on effect is influenced to a certain extent, and not can avoid this hemorrhage infiltration syringe needle during being punctured and entered extraction
In joint fluid, thus it is proposed that a kind of rheumatism joint fluid removes hemorrhage draw-out device.
Summary of the invention
The purpose of this utility model is to provide a kind of rheumatism joint fluids to remove hemorrhage draw-out device, to solve above-mentioned background
The problem of being proposed in technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of rheumatism joint fluid is extracted except hemorrhage
Device, including syringe, the syringe left end is integrally formed with connection mouth, and the syringe right end is integrally formed with holding seat, the needle
Cylinder internal slide is equipped with piston, and the piston right end is installed with pull rod, and the pull rod right end is integrally formed with pulling seat；
The cavity wall of the connection mouth and syringe junction is provided with the card slot of annular, and the card slot of the annular is installed with rubber
Bayonet lock, the rubber card pin-shaped shape are the prominent annular bayonet lock of edge, the rubber card pin circular inside diameters integrally formed with connection rubber ring,
The connection rubber ring internal diameter integrated molding is flexible to tighten mouth, and the connection rubber ring is integrally formed close to the right side of internal diameter
There is package ball；
The syringe outer wall figure is carved with scale；
The connection mouth shape is left thin right thick truncated conical shape；
Hyperbolic-type groove is provided at the pull rod connection pulling seat.
The working principle and process of the utility model:
When piercing needle is pierced into patient articular, tissue can penetrate into blood from overflowing in syringe needle, pull pulling seat, pass through pull rod
Drive piston moves right in syringe, generates negative pressure, while wrapping up ball under the action of negative pressure and elastic deformation occurs, will
Negative pressure is transmitted to connection mouth, then wants to extract the joint fluid in joint in suction function, while remaining in syringe needle being overflow
Blood enters in package ball, and when negative pressure is sufficiently large, rubber bayonet lock is detached from from card slot, will under the action of elasticity tightens mouth
Package ball is sealed, and is prevented internal hemorrhage from flowing out, is removed the hemorrhage in the joint fluid of extraction.
The utility model has the beneficial effects that
Hemorrhage is collected by wrapping up ball, reduces the content of the hemorrhage in the joint fluid of extraction, and is being extracted
In the process, the hemorrhage penetrated into syringe needle is carried out package collection by package ball, while under the action of negative pressure, and rubber bayonet lock is from card
It separates in slot, package ball is closed under the action of elasticity tightens mouth, avoid package inside package ball
Hemorrhage leaks again.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is detail view at a in Fig. 1.
Specific embodiment
Please refer to shown in Fig. 1 and Fig. 2, the utility model provides a kind of technical solution: a kind of rheumatism joint fluid is except hemorrhage
Draw-out device, including syringe 1, cooperation piston 3 generate negative pressure extracting joint fluid, while to the position that the joint fluid of extraction is collected
It sets, 1 left end of syringe connects external puncture syringe needle, external puncture syringe needle is connected to syringe 1 integrally formed with connection mouth 2,
Gripping claw, stable operation, the syringe 1 is fixed to syringe 1 in use process integrally formed with seat 6 is held in 1 right end of syringe
Internal slide is equipped with piston 3, and cooperation syringe 1, which makes to generate inside syringe 1 under the action of pull rod 4, detaches negative pressure, the piston 3
Right end is installed with pull rod 4, and 4 right end of pull rod pulls to the right piston 3 integrally formed with pulling seat 5, the two cooperation, generates work
Required negative pressure；
The connection mouth 2 is provided with the card slot 10 of annular with the cavity wall of 1 junction of syringe, and rubber bayonet lock 7 is fixed
Dress, limits the operating position of rubber bayonet lock 7 and its integrally formed structure under normal conditions, and the card slot 10 of the annular is installed with rubber
Installation is fixed to the integrally formed structure of rubber bayonet lock 7 in glue bayonet lock 7, and 7 shape of rubber bayonet lock is the prominent annular snap of edge
Pin heaves inner ring flat pattern for peripheral cylindrical shape, and cooperation card slot 10 is installed and used, 7 circular inside diameters of rubber bayonet lock
Integrally formed with connection rubber ring 8, entire 2 inner cavity of connection mouth is closed, realizes the collection to hemorrhage, the connection rubber
8 internal diameter of ring be integrally formed it is flexible tightens mouth 9, when rubber bayonet lock 7 is detached from from card slot 6, under the action of elasticity tightens power into
Row tightens closing, so that package ball becomes a closed sphere, the connection rubber ring 8 is close to the right side of internal diameter one
It is body formed to have package ball 11, the hemorrhage being collected into is collected and is wrapped up；
The 1 outer wall figure of syringe is carved with scale, and observation is facilitated to extract the amount of joint fluid；
2 shape of connection mouth is left thin right thick truncated conical shape, and the installation of external puncture syringe needle is facilitated to connect；
The pull rod 4 connects and is provided with hyperbolic-type groove at pulling seat 5, i.e. the tangent line infinite approach of groove right end face is parallel
One is able to carry out in the axis of pull rod 4, but never parallel curves type groove, when so that pull rod 4 is by unbalanced force by pulling seat 5
Self adjustment for determining angle, realizes the equilibrium of effective operational forces.
The working principle and process of the utility model:
It please refers to shown in Fig. 1 and Fig. 2, when piercing needle is pierced into patient articular, blood from overflowing can be penetrated into syringe needle by tissue
In, pulling seat 5 is pulled, is moved right in syringe 1 by 4 drive piston 3 of pull rod, generates negative pressure, while under the action of negative pressure
It wraps up ball 11 and elastic deformation occurs, negative pressure is transmitted to connection mouth 2, is then want in suction function by the joint in joint
