Abstract
The utility model relates to a pericardial puncture needle and belongs to the field of medical apparatus and instruments. The puncture needle is sheathed with a plastic casing pipe which is marked with casing pipe marks; the front end of the puncture needle is a blunt needle tip; and the plastic casing pipe is processed with a plurality of side holes. As the tip of the puncture is blunt, the puncture needle does not easily puncture the heart; the wall of the puncture needle is marked with the marks so that when the puncture needle is operated, the depth of the needle insertion can be controlled, thus leading the operation to be simpler and safer. The head end of the casing pipe is provided with the side holes so that the casing pipe is not easily blocked.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of paracentesis pericardii pin that is used for the patient of pericardial effusion is carried out the paracentesis pericardii drawing liquid.
Background technology
As everyone knows, when being expert at paracentesis pericardii, the most dangerous complication is stabbed heart exactly.And used its pin wall of paracentesis pericardii pin does not have scale at present, and complication often takes place the depth of needle inaccuracy.After puncturing successfully, its sharp needle point is trapped in the pericardial cavity, and the patient need hold pin for a long time and fixedly carry out tapping, and so easy generation is tired, and needle point is fixing insecure and stab heart, and the puncture needle head end do not have side opening, easily gets clogged.
Summary of the invention
In order to overcome the danger of the sad bag of existing paracentesis pericardii pin spinosity, reach the shortcoming that puncture needle easily gets clogged, this utility model provides a kind of paracentesis pericardii pin, the purpose of this paracentesis pericardii pin is to overcome above-mentioned deficiency, a kind of disposable safe easy operating is provided, is fit to the paracentesis pericardii pin that hospitals at different levels use.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of paracentesis pericardii pin, be provided with puncture needle, be set with plastic bushing on the puncture needle, plastic bushing is marked with the sleeve pipe scale, the puncture needle front end is the passivity needle point, is processed with a plurality of side openings on the plastic bushing.
The beneficial effects of the utility model are, because puncture needle tip is passivity, so be difficult for stabbing heart, puncture needle pin wall indicates scale, can grasp the degree of depth of inserting needle during operation, make to operate to become simpler, and safety, the sleeve pipe head end is provided with side opening, and sleeve pipe should not block.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1, structural representation of the present utility model.
1. passivity needle points among the figure, 2. plastic bushing, 3. sleeve pipe scale, 4. plastic bushing extended spot, 5. plastic bushing joint, 6. puncture needle, 7. side opening.
The specific embodiment
In Fig. 1, this utility model is provided with puncture needle 6, be set with plastic bushing 3 on the puncture needle 6, plastic bushing 3 is marked with sleeve pipe scale 3, so that grasp depth of needle, the passivity needle point 1 of puncture needle 6 front ends is a passivity, can effectively avoid stabbing heart, be processed with a plurality of side openings 7 on the plastic bushing 2, can prevent effectively that sleeve pipe from getting clogged, plastic bushing 2 ends are followed successively by plastic bushing extended spot 4 and plastic bushing joint 5.
