Description
Technical field
This utility model relates to the technical field of medical apparatus and instruments, particularly a kind of Cardiological tapping device.
Background technology
Pericardial effusion is a kind of common Cardiological disease, at present, the Therapeutic Method of pericardial effusion mainly leans on puncture needle by paracentesis pericardii and is extracted out by hydrops, but existing sting device is covered, when removing cap body by puncture needle plastic cap body, easily stab medical worker, in the process of puncture, whole needle body is exposed in external environment condition completely, can not according to the length of the required needle body of position adjustment of pericardium.
Utility model content
In order to solve the deficiency of above-mentioned prior art, the purpose of this utility model is: provide a kind of position according to pericardium to adjust the Cardiological tapping device of needle body length.
Invention thought of the present utility model is: be sealed in by puncture needle in sleeve, promotes piston push rod A, is released by puncture needle in sleeve, after determining the position of pericardium, shift piston push rod A onto suitable position, with stopping means, piston push rod is fixed, carry out puncturing and drawing liquid.
A kind of Cardiological tapping device, comprise puncture needle, described puncture needle is fixedly connected with piston A, the sleeve that described piston A arranged outside coordinates with described piston A, described barrel forward end is provided with pin hole, described pin hole is coated with diaphragm seal, described sleeve lateral wall is provided with through hole, outside described sleeve, described through hole is provided with support, described support is fixedly connected with described sleeve cylinder is vertical, described support is provided with stopping means, described stopping means is arranged on inside described sleeve through described through hole, described piston A rear end is provided with piston push rod A, described piston push rod A is also arranged in described sleeve, described piston push rod A is hollow cylindrical, the described piston push rod A of hollow cylindrical communicates with described puncture needle, piston B and piston push rod B is provided with inside described piston push rod A, described piston push rod A arranged outside has tooth bar, described tooth bar engages with described stopping means.
Described diaphragm seal is aluminium foil or tin-foil plate.
Described support and described stopping means hinged.
Described stopping means is bar linkage structure.
Described stopping means comprises connecting rod A and the connecting rod B hinged with described connecting rod A.
Described connecting rod B is vertically set on the between cog of described tooth bar through described through hole.
During utility model works, by connecting rod A toward pressing down, promoting piston push rod A and moving forward, according to the position of the pericardium of data display, shift piston push rod A onto suitable position, unclamp connecting rod A, connecting rod B embeds in slot, is fixed by piston push rod A, now, puncture needle is thrust pericardium position, pull piston rod B, hydrops is extracted out in the body.
By test, the beneficial effects of the utility model are: structure is simple, is sealed in by puncture needle in sleeve, effectively avoids the pollution of external environment condition to needle body, meanwhile, when medical worker works, be not easy to stab, can according to the position of pericardium, the length of the required needle body of adjustment, practical.
