Abstract
The utility model relates to a pericardiocentesis needle fixer, which belongs to the technical field of medical appliances, and comprises a fixed plate, a binding course, an inserting plate and a support spring. The pericardiocentesis needle fixer is characterized in that the periphery of the bottom surface of the rectangle fixed plate is provided with the binding course; the inside of the fixed plate is provided with a rectangle cavity one end of which is open; the inserting end of the inserting plate which is arranged in the cavity and suited to the cavity is connected with the support spring fixed on the bottom of the cavity; and the plate surfaces of the inserting plate and the fixed plate are respectively provided with through holes which correspond to each other. The pericardiocentesis needle fixer has the advantages that the fixer has simple structure and convenient use, saves time and labor, has firm fixation of the pericardiocentesis needle, can avoid the stabbing of the cardiac muscle by the pericardiocentesis needle and the long time needle holding of the operator, and can improve the working efficiency.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of paracentesis pericardii needle lock.
Background technology
At present, often need carry out paracentesis pericardii to the inspection of diseases such as pericardial effusion and treatment, puncture successfully after, the needle point need long period that puncture needle is sharp is retained in the pericardial cavity, during the patient must hold pin for a long time and fix, be easy to generate fatigue; And puncture needle causes cardiac muscle to be wounded by stabbing often because of fixing not firm the displacement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy to operate, the puncture needle fixation can be able to not stabbed the paracentesis pericardii needle lock of cardiac muscle.
The purpose of this utility model is achieved in that this paracentesis pericardii needle lock is made of fixing head, tack coat, plate, support spring, rectangle fixing head bottom periphery is provided with tack coat, inside is provided with the open rectangular cavity of an end, cavity plate insertion end interior and that cavity adapts links to each other with the fixed support spring of cavity bottom, is respectively equipped with the through hole of mutual correspondence on plate plate face and the fixing head plate face.Tack coat forms by medical silica-gel or by other any, antiallergic nontoxic, harmless to human body, adhesive material.
During use, with hands extruding plate outer end, through hole above the plate is alignd with through hole above the base plate, puncture needle punctures after passing through hole, after puncturing successfully, under the support spring effect, thereby base plate and the through hole above the plate is interlaced that puncture needle is fixed utilizes the tack coat of fixing head bottom surface that fixing head is adhesively fixed on patient's thoracic wall at last and gets final product.
Advantage of the present utility model: simple in structure, easy to use, time saving and energy saving, the puncture needle fixation can avoid puncture needle to stab cardiac muscle and the patient holds pin for a long time, increases work efficiency.
