Description
Technical field
The present invention relates to internal medicine technical field of medical instruments.
Background technology
Clinically, to the treatment of pericardial fluid patient, the method adopting puncture to extract more.At present, the traditional syringe needle of general employing punctures, and because needle tip is comparatively sharp-pointed, and after penetrating pericardium, because heart is beated always, needle point is easy to stab cardiac muscle, even causes sudden cardiac arrest, there is very large potential safety hazard.Some scheme adopts extension-type puncture needle, but the operation of this puncture needle comparatively bothers, and is easy to make air enter in pericardium, also very undesirable in puncture effect.
For the problems referred to above, application number is that the Chinese invention patent of 201220621145.X discloses a kind of trailing type pericardial fluid pumping device, and its plunger utilizing front end round and smooth prevents from stabbing cardiac muscle, utilizes air pressure to control the displacement of plunger.Reduce the risk of stabbing cardiac muscle to a certain extent.
Application number be 201220064379.9 Chinese invention patent also disclose a kind of trailing type pericardial fluid pumping device, it utilizes piercing needle to bring sleeve into pericardium, utilizing and can the structure of piercing needle in retraction sleeve preventing from stabbing cardiac muscle, also reduce the risk of stabbing cardiac muscle to a certain extent.
From current published intracardiac puncture needle structure, be all fixing syringe needle is changed in order to prevent from stabbing cardiac muscle the structure that can retract.As everyone knows, the amplitude of beating of heart substantially exceeds the thickness of pericardium, and the structure of needle retractable starts to play a role after all first penetrating pericardium with syringe needle, will have following problem like this:
When syringe needle penetrates pericardium, operator cannot learn that pericardium position is with the amplitude of beating of heart and jumping frequency rate, and when pericardium is in the crest of beating, syringe needle penetrates pericardium, then the wave trough position of beating, and syringe needle is deviate from pericardium; When jumping to the position of crest again, syringe needle then penetrates pericardium again, and the syringe needle of such retraction structure does not also have action, repeatedly penetrates pericardium.When syringe needle penetrates when pericardium is in the position of trough of beating, then pericardial layer is pierced through in the position that may appear at crest, injures cardiac muscle.
The structure that above-mentioned problem thrusts rear retraction from single syringe needle is insurmountable, and basic reason is that beating of heart makes syringe needle can not stablize in the intrapericardial degree of depth.If realize syringe needle to stablize in the intrapericardial degree of depth, structure, thoroughly should change the fixed structure of puncture needle, the syringe needle of puncture needle is under the kinestate of, both geo-stationary synchronous with heartbeat.
Summary of the invention
Technical problem to be solved by this invention, it is the technical deficiency for above-mentioned existence, a kind of trailing type pericardial fluid pumping device is provided, can to keep with heart synchronously beating along with beating of heart after its tapered needle penetrates pericardium, make tapered needle and pericardium keep relative static conditions, fundamentally avoid the problem that cardiac muscle stabbed by syringe needle.
The technical solution used in the present invention is: provide a kind of trailing type pericardial fluid pumping device, comprise trailing type pericardial fluid pumping device, it is characterized in that: comprise guiding tube, puncture tube, sealing cap, drainage tube;
Described puncture tube comprises: be positioned at the tapered needle of lower end, be positioned at the slide-and-guide pipe on tapered needle top; Tapered needle inside is the syringe needle chamber of docking conducting with the tube chamber of slide-and-guide pipe; The side of tapered needle evenly has the conduction hole with the conducting of syringe needle chamber; Syringe needle intracavity is provided with blocking head; The lower end of blocking head is provided with the projection be sealed and matched with conduction hole; Puncture tube is positioned at guiding tube and slide-and-guide pipe coordinates with the slipper seal of guiding tube inwall; The outer wall of slide-and-guide pipe is provided with guide pad; The inwall of guiding tube is provided with the stopper slot be slidably matched with guide pad; The upper end of stopper slot is provided with the protection spacing ring that internal diameter is less than slide-and-guide pipe external diameter;
The bottom outer wall loose joint of described guiding tube has locating ring; The lower end outer wall of guiding tube is provided with the corner cut conical surface seamlessly transitting with tapered needle and coordinate; Upper end and the sealing cap of guiding tube are tightly connected; A action bars and B action bars is provided with in guiding tube; A action bars lower end and slide-and-guide pipe are fixed; The upper end of A action bars penetrates sealing cap end face and coordinates with sealing cap slipper seal; The top of A action bars is provided with and pushes away handle; B action bars is positioned at A action bars and A action bars threaded engagement; The lower end of B action bars is rotationally connected with blocking head; The upper end of B action bars extends to outside and is provided with release button on top in A action bars;
The top of described drainage tube is communicated with sealing cap at sealing cap sidewall; The end of drainage tube is the taper type plug coordinated with syringe; Voltage stabilizing capsule is communicated with at the middle part of drainage tube.
Further optimization the technical program, trailing type pericardial fluid pumping device in the bottom pushing away handle, A action bars is provided with degree of depth spacing ring.
Further optimization 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:
1, can keep first to resting state with pericardium after tapered needle penetrates pericardium, fundamentally avoid the problem of stabbing cardiac muscle: press down guiding tube, under the drive of guiding tube, the tapered needle of puncture tube and the lower end of guiding tube penetrate in patient body, under the stop of locating ring, tapered needle is sent into close to the position of pericardium and stop motion by guiding tube, according to the heart beating rule of patient, press down at the crest place of beating and push away handle, tapered needle is penetrated patient's pericardium; Then unclasp and push away handle, because the slide-and-guide pipe of puncture tube coordinates with the inwall slipper seal of puncture tube, and tapered needle can be subject to the frictional force that pericardial tissue extruding produces when penetrating patient's pericardium, under the drive changing frictional force, puncture tube synchronously will slide along with beating of heart in guiding tube, keeps geo-stationary with pericardium.
2, in the process penetrating tapered needle, tapered needle is in blocked state, when after tapered needle and pericardium synchronized movement, by rotating B action bars, blocking head can be pulled away from conduction hole, thus ensure that hydrops is extracted out smoothly.The structure of blocking head is avoided penetrating in process and is entered gas.
3, when using syringe to extract pericardial effusion, because puncture tube slides in guiding tube along with heartbeat, the negative pressure in guiding tube can be caused back and forth to be elevated thereupon, drainage tube is communicated with voltage stabilizing capsule, the change in volume of voltage stabilizing capsule can be utilized to balance the reciprocal lifting of negative pressure, ensure stability during syringe extracting liquid.
4, tapered needle is provided with developing ring, contributes to learning the position of tapered needle under development environment, make tapered needle to penetrate the degree of depth more intuitively controlled.
5, degree of depth spacing ring can penetrate depth-set according to the maximum of patient's pericardial layer, stabs cardiac muscle when preventing crest from penetrating pericardium.
