Description

Trailing type pericardial fluid pumping device
Technical field
The present invention relates to internal medicine technical field of medical instruments.
Background technology
Clinically, the treatment to pericardial fluid patient, more using the method for puncturing extraction.At present, typically using traditional pin Head is punctured, and as needle tip is more sharp, and after penetrating pericardium, as heart is beated always, needle point is easy to stab Cardiac muscle, or even cause sudden cardiac arrest, there is very big potential safety hazard.Some schemes adopt extension-type puncture needle, but this puncture Pin operation is more bothered, it is easy to admitted air in pericardium, also very undesirable on effect is punctured.
For the problems referred to above, the Chinese invention patent of Application No. 201220621145.X discloses a kind of trailing type pericardium Liquid pumping device, which prevents from stabbing cardiac muscle using the round and smooth plunger in front end, controls the displacement of plunger using air pressure.To a certain degree On reduce stab cardiac muscle risk.
The Chinese invention patent of Application No. 201220064379.9 also discloses that a kind of trailing type pericardial fluid pumping device, Which brings sleeve into pericardium using piercing needle, can prevent from stabbing the heart with the structure of the piercing needle in retraction sleeve utilizing Flesh, also reduces the risk for stabbing cardiac muscle to a certain extent.
From the point of view of current published intracardiac puncture needle structure, be provided to prevent to stab cardiac muscle and by fixed syringe needle It is changed to the structure that can be retracted.It is well known that the bounce amplitude of heart substantially exceeds the thickness of pericardium, and the structure of needle retractable All first penetrated with syringe needle and start to play a role after pericardium, thus have following problem：
When syringe needle penetrates pericardium, operator cannot learn bounce amplitude and jumping frequency rate of the pericardium position with heart, take care When bag is in the crest of bounce, syringe needle penetrates pericardium, then in the wave trough position of bounce, syringe needle is deviate from from pericardium；When again When jumping to the position of crest, syringe needle then penetrates again pericardium, the also no action of syringe needle of such retraction structure, repeatedly Penetrate pericardium.Penetrate when syringe needle is in the position of bounce trough in pericardium, then the heart is pierced through in the position for being likely to appear in crest Covering, injures cardiac muscle.
The structure that above-mentioned problem is retracted after being pierced into from single syringe needle is insurmountable, and basic reason is heart Bounce prevents syringe needle in intrapericardial depth from stablizing.If syringe needle to be realized is stable in intrapericardial depth, it should from structure The upper fixed structure for thoroughly changing puncture needle, makes the syringe needle of puncture needle in fortune synchronous with heartbeat, both geo-stationaries Under dynamic state.
The content of the invention
The technical problem to be solved, is for above-mentioned technical deficiency, there is provided a kind of trailing type pericardium Liquid pumping device, its tapered needle can make taper pin with the bounce of heart bounce synchronous with heart holding after penetrating pericardium Head keeps relative static conditions with pericardium, fundamentally avoids the problem that syringe needle stabs cardiac muscle.
The technical solution used in the present invention is：A kind of trailing type pericardial fluid pumping device is provided, including trailing type pericardial fluid Pumping device, it is characterised in that：Including guiding tube, puncture tube, sealing cap, drainage tube；
The puncture tube includes：Tapered needle positioned at lower end, positioned at the slide-and-guide pipe on tapered needle top；Taper pin The internal syringe needle chamber for being to dock with the tube chamber of slide-and-guide pipe conducting of head；The side of tapered needle is uniformly provided with and is turned on syringe needle chamber Conduction hole；Syringe needle intracavity is provided with blocking head；The lower end of blocking head is provided with and is sealed the projection for coordinating with conduction hole；Puncture tube position In guiding tube and slide-and-guide pipe with guiding inside pipe wall be slidingly sealed cooperation；The outer wall of slide-and-guide pipe is provided with guide pad； The inwall of guiding tube is provided with the stopper slot being slidably matched with guide pad；The upper end of stopper slot is provided with internal diameter less than slide-and-guide The protection spacing ring of pipe external diameter；
The bottom outer wall loose joint of the guiding tube has locating ring；The lower end outer wall of guiding tube is provided with smooth with tapered needle The corner cut conical surface of interference fits；The upper end of guiding tube is tightly connected with sealing cap；A action bars and B action bars is provided with guiding tube； A action bars lower end is fixed with slide-and-guide pipe；The upper end of A action bars penetrates sealing cap top surface and is slidingly sealed cooperation with sealing cap；A The top of action bars is provided with push handle；B action bars is located in A action bars and is coordinated with A action bars screw thread；The lower end of B action bars with Blocking head rotates connection；The upper end of B action bars extends to outside from A action bars and is provided with separation knob on top；
The top of the drainage tube is connected with sealing cap in sealing cap side wall；The end of drainage tube is the frustum coordinated with syringe Shape plug；Voltage stabilizing capsule is communicated with the middle part of drainage tube.
Further optimize the technical program, the bottom in push handle of trailing type pericardial fluid pumping device is installed on A action bars There is depth spacing ring.
Further optimize the technical program, the tapered needle of trailing type pericardial fluid pumping device is provided with developing ring.
The invention has the beneficial effects as follows：
1st, can keep first to resting state with pericardium after tapered needle penetrates pericardium, fundamentally avoid and stab cardiac muscle Problem：Guiding tube is pushed, the tapered needle of puncture tube and the lower end of guiding tube are penetrated in patient's body under the drive of guiding tube, Under the stop of locating ring, guiding tube is sent into the position i.e. stop motion for being close to pericardium by tapered needle, according to the heart beating of patient Rule, at the crest of bounce pushes push handle, tapered needle is penetrated patient's pericardium；Then push handle is unclasped, due to puncture tube Slide-and-guide pipe is slidingly sealed cooperation with the inwall of puncture tube, and tapered needle can be squeezed by pericardial tissue when penetrating patient's pericardium The frictional force that pressure is produced, under the drive of the frictional force, puncture tube will be synchronous sliding in guiding tube with the bounce of heart It is dynamic, geo-stationary is kept with pericardium.
2nd, during tapered needle is penetrated, tapered needle is in blocked state, when tapered needle and pericardium are moved together After step, head pull-off conduction hole can will be blocked by rotating B action bars, so as to ensure that hydrops is smoothly extracted out.The structure of blocking head Gas is entered during avoiding penetrating.
3rd, when pericardial effusion is extracted using syringe, as puncture tube slides in guiding tube with heartbeat, The negative pressure in guiding tube can be caused back and forth to lift therewith, connect voltage stabilizing capsule on drainage tube, it is possible to use the change in volume of voltage stabilizing capsule Balance the reciprocal lifting of negative pressure, it is ensured that syringe extracts stability during liquid.
4th, developing ring is provided with tapered needle, contribute to learning the position of tapered needle under development environment, make taper Syringe needle to penetrate depth more directly perceived controllable.
5th, depth spacing ring can penetrate depth-set according to the maximum of patient's pericardial layer, prevent crest from piercing when penetrating pericardium Sad flesh.
