Abstract
The invention discloses a location puncture needle with scale display. The puncture needle comprises a needle head, wherein the needle head is connected to a needle base; a branch tube is arranged on the needle base; a check valve is arranged in the branch tube; a plurality of main scale marks and auxiliary scale marks are arranged on the needle head; and a locating screw cap sleeves the needle head. A needle head length mark is additionally arranged on the needle base. A fixed device is arranged on the puncture needle of the invention and the fixed device is moved to the corresponding position of a body surface after successful puncture and is fixed, so that medical personnel can master a punctured depth easily during operating, and the operator can feel more assured since the puncture needle is prevented from sliding forth and back; in addition, the puncture needle can relieve complications caused by human factors in the puncture, improve the success rate of the puncture, reduce medical risks, reduce medical disputes and relieve pain in patients.
Description
Technical field
The present invention relates to a kind of puncture needle, be specifically related to a kind of with puncture needle that is with a scale and fixture, medical worker in hospital can be widely used in and do in puncturing operation.
Background technology
Many dropsies of serous cavity and pneumothorax are the common diseases of various big hospital, breast chamber, abdominal cavity, the paracentesis such as pericardial cavity are also the operations that various big hospital is generally carried out, the symptom of the rapid reduction of patient of paracentesis energy provides the help of necessity also to the etiological diagnosis of many dropsies of serous cavity patient, but the puncture needle of various big hospital use is at present still unsatisfactory, because of existing puncture needle do not have scale mark or scale mark unintelligible, fixture is not had yet, so be expert at, during puncture, operator is not easy the depth holding puncture, and the easy slide anteroposterior of puncture needle and not easily being perceiveed by operator, especially breast intracavity gas and breast abdomen, when the hydrops amount of pericardium is few, very easily damaging normal tissue, potential risk is brought to puncture, existing needle length is single, and to the hydrops compared with position, deep, especially encapsulated effusion, conventional puncture needle is usually difficult to the position arriving hydrops, can not meet the requirement of clinical worker.
Summary of the invention
Technical problem to be solved by this invention is for operator grasps paracentesis depth more accurately, and the puncture needle of different length model is provided, make operator more relieved, improve puncture success rate, and reduce the artificial complication occurred in puncture, reduce medical-risk, reduce medical tangle, alleviate the misery of patient.Even a small amount of hydrothorax and gas, also can relievedly operate after ultrasonic or rabat are fixed a point and determined paracentesis depth.
The object of the present invention is achieved like this: a kind of positioning puncture needle of display with a scale, and comprise syringe needle, syringe needle is connected with needle stand, needle stand is provided with branched pipe, be provided with check valve in branched pipe, syringe needle be provided with multiple major tick marks and subscale mark labelling, syringe needle is set with positioning screw cap.Needle stand is also provided with needle length labelling.
Described subscale mark labelling is between two adjacent major tick marks.
Distance between two adjacent major tick marks is 1 centimetre.
The positioning puncture needle of display with a scale provided by the invention, puncture needle is provided with fixture, successfully, fixture being moved on to corresponding sites wait puncturing also fixing, allowing medical worker be easy in operation grasp the degree of depth punctured, and preventing puncture needle slide anteroposterior, make operator more relieved, and reduce the artificial complication occurred in puncture, improve puncture success rate, reduce medical-risk, reduce medical tangle, alleviate the misery of patient.Branched pipe side opening with unidirectional valve can also be used for into seal wire, guides inlying catheter.
Adopt the main and auxiliary identification method helping scale to combine, accurately, promptly can determine paracentesis depth.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is scale mark schematic diagram of the present invention.
Fig. 3 is schematic diagram of the present invention.
Detailed description of the invention
Structure of the present invention is as shown in Figure 1-2: a kind of positioning puncture needle of display with a scale, comprise syringe needle 1, syringe needle 1 is connected with needle stand 2, needle stand 2 is provided with branched pipe 4, check valve 5 is provided with in branched pipe 4, syringe needle 1 is provided with multiple major tick marks 6 and subscale mark labelling 7, syringe needle 1 is set with positioning screw cap 3, needle stand 2 is also provided with needle length labelling 8.
In the present invention, subscale mark labelling 7 is positioned at adjacent, and under normal circumstances, the distance between two adjacent major tick marks 6 is 1 centimetre; Subscale mark labelling 7 equidistantly distributes between two major tick marks 6.
Major tick marks 6 of the present invention and subscale mark labelling 7 utilize industrial steel piece surface turn blue blackout handling principle obtain.Labelling on needle length labelling 8 is identical with the length of syringe needle 1.
When the present invention uses, by the length of the known syringe needle 1 of needle length labelling 8, puncture needle is carrying out in the process punctured, after a of thoracic cavity, by major tick marks 6 and subscale mark labelling 7, user can grasp the degree of depth punctured, after completing puncture, also can determine the degree of depth punctured.After completing puncture, rotate positioning screw cap 3, also fixing after being moved on to the sites of paracentesis depth, puncture needle slide anteroposterior in piercing process can being prevented, by being connected with syringe, liquid collecting b can be extracted out.
Positioning screw cap 3 adopts transparent duroplasts to make, and left-handed is pine, and dextrorotation is tight.
