Description
Technical field
The utility model relates to medical instrument, especially a kind of thoracic cavity liquid pumping needle.
Background technique
The way of pleural effusion is medically aspirated now are as follows: is used blood transfusion apparatus, snorkel, is connect empty needle and puncture into patient's pleura
Chamber aspirates pleural effusion.Since the syringe needle of puncture needle is hard sharp keen, lung bounces back after aspirating pleural effusion, and the lung of retraction encounters needle point
It can be punctured, puncturing lung will cause artificial pneumothorax.In addition, the length that puncture needle enters human body needs to control, it is needled into if puncturing
The length of human body is too long, will increase the probability for damaging other organs.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of thoracic cavity liquid pumping needles, solve skill of the existing technology
Art problem.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of thoracic cavity liquid pumping needle, including casing seat,
Casing, liquid suction pipe and needle assemblies, the needle assemblies include needle core and needle stand, and one end of casing seat is arranged in the needle stand, described
The other end of casing seat gradually narrows and forms connecting pin, and the connecting pin of casing seat is equipped with the opening being pierced by for needle core, described sleeve pipe
It is equipped with rubber stopper in seat, is equipped with the through-hole passed through for needle core among rubber stopper；The first end of described sleeve pipe and connecting pin plug connect
It connecing, the syringe needle of needle core stretches out outside the second end of casing, and syringe needle is equipped with the first inclined-plane, and the second end of casing is equipped with the second inclined-plane,
First inclined-plane is consistent with the gradient on the second inclined-plane；One end of the liquid suction pipe is connected to casing seat, and the other end connects equipped with aspirator
Head；The surface of described sleeve pipe is equipped with scale.The utility model principle: when suction hydrops, needle core connection casing is pierced into human body together,
The needle core of metal is hard not to allow flexible, guiding of the needle core as casing, and guiding sleeve reaches designated position；After puncture, pass through
Needle stand pulls out needle core, leaves passivity plastic bushing, will not damage encountering casing when lung bounces back after taking out hydrops.Casing is pierced into
The inclined-plane at end and the slope of syringe needle are consistent, and casing is made to be easier that needle core is followed to be pierced into vivo.Casing is equipped with scale, convenient
Medical staff accurately control casing be pierced into human body length.
As an improvement, described sleeve pipe inner wall is set, there are four the protrusion being circularly and evenly distributed, the tables of the protrusion and needle core
Face contact.
As an improvement, the protrusion is triangular in shape.
As an improvement, the surface of the connecting pin is set, there are four the groove being circularly and evenly distributed, the groove and protrusions
Cooperation.
Brought beneficial effect is the utility model compared with prior art:
Needle core is pulled out by needle stand, leaves passivity plastic bushing, it will not encountering casing when lung bounces back after taking out hydrops
Damage；The inclined-plane that casing is pierced into end is consistent with the slope of syringe needle, and casing is made to be easier that needle core is followed to be pierced into vivo；On casing
Equipped with scale, facilitating medical staff, accurately control casing is pierced into the length of human body.
Detailed description of the invention
Fig. 1 is the utility model section view.
Fig. 2 is cannula structure schematic diagram.
Fig. 3 is the section view of casing and needle core cooperation.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of thoracic cavity liquid pumping needle, including casing seat 1, casing 3, liquid suction pipe 5 and needle assemblies, the needle assemblies
Including needle core 2 and needle stand 6.One end of casing seat 1 is arranged in the needle stand 6, and part and needle in casing seat 1 is arranged in needle stand 6
The tail end of core 2 connects, and needle stand 6 is arranged in the part outside casing seat 1 and forms hand-held part, and medical staff operates needle core by hand-held part
2.The other end of described sleeve pipe seat 1 gradually narrows and forms connecting pin 11, and the connecting pin 11 of casing seat 1 is equipped with to be pierced by for needle core 2
Opening, described sleeve pipe seat 1 is interior to be equipped with rubber stopper 4, is equipped with the through-hole passed through for needle core 2 among rubber stopper 4.The of described sleeve pipe 3
One end and the plug of connecting pin 11 connect, and the syringe needle of needle core 2 stretches out outside the second end of casing 3, and syringe needle is equipped with the first inclined-plane, casing
3 second end is equipped with the second inclined-plane, and the first inclined-plane is consistent with the gradient on the second inclined-plane, the inclined-plane and syringe needle at the piercing of casing 3 end
Slope is consistent, and casing 3 is made to be easier that needle core 2 is followed to be pierced into vivo.One end of the liquid suction pipe 5 is connected to casing seat 1, separately
One end is equipped with aspirator connector, and when aspirating hydrops, aspirator is connect with liquid suction pipe 5 extracts hydrops.As shown in Fig. 2, described sleeve pipe 3
Surface be equipped with scale 7, which can show the length of casing 3, and facilitating medical staff, accurately control casing 3 is pierced into people
The length of body.As shown in figure 3,3 inner wall of described sleeve pipe is set there are four the protrusion 8 being circularly and evenly distributed, described raised 8 be in triangle
Shape, described raised 8 contact with the surface of needle core 2, and when due to pulling out needle core 2, needle core 2 is relatively moved with casing 3, protrusion 8
It can play the role of being oriented to needle core 2, and the frictional force between 3 inner wall of needle core 2 and casing can be reduced, hold that needle core 2 more
Easily pulled out；In addition, casing 3 is retained in human body after needle core 2 is pulled out, it is desirable that casing 3 has good bending resistance and anti-flattening
It can be to prevent casing 3 from occluding, protrusion 8 can be used for the intensity of reinforcing sleeve 3.The surface of the connecting pin 11 is in circle there are four setting
All equally distributed grooves, the groove and protrusion 8 cooperate；Since casing 3 and casing seat 1 are individual components, built-up time set
Pipe 3 is inserted on casing seat 1, and groove and the cooperation of protrusion 8 can not only make the combination of casing 3 and casing seat 1 more firm, Er Qieke
To determine the direction of casing 3, the inclined-plane for making it be pierced into end is consistent with the bevel direction of syringe needle.
The utility model principle: when suction hydrops, needle core 2 is connected to casing 3 and is pierced into human body together, and the needle core 2 of metal is hard
Flexible, guiding of the needle core 2 as casing 3 is not allowed, guiding sleeve 3 reaches designated position；After puncture, needle is pulled out by needle stand 6
Core 2 leaves passivity plastic bushing 3, will not damage encountering casing 3 when lung bounces back after taking out hydrops.
