Abstract
The utility model relates to a Y-shaped pericardial puncture needle with high safety, convenient operation and good tightness. The pericardial puncture needle belongs to a medical device. The Y-shaped pericardial puncture needle comprises a needle seat which takes the shape of Y and is provided three open ends with one end hermetically connected with a needle body, the needle head end of the needle body is provided with an inclined side hole and the external wall of the needle body is provided with graduation lines; the other end of the needle seat is hermetically connected with a lead line,, the third end of the needle seat is hermetically connected with a tee valve, and one end of the tee valve is hermetically connected with a drainage tube. By adopting the Y-shaped pericardial puncture needle in a pericardial paracentesis, blockage can be avoided, the puncturing depth can be accurately controlled, tightness of the lumen is guaranteed, pericardial effusion is easy to be extracted and medicine is easy to be injected into the pericardial cavity.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of Y centre of form free clothing pricker that uses when the pericardial effusion patient is carried out clinic diagnosis.
Background technology
Paracentesis pericardii is a kind of high-risk operation, often cause puncture failure, also cross sometimes and stab cardiac muscle deeply, pericardial tamponade danger takes place because of inserting needle because of inserting needle is not in place, at present clinical used puncture needle does not have the electrocardiograph connecting line that leads, can't use electrocardiograph and monitor puncture needle and whether contact the heart adventitia, and the puncture needle wall does not have scale, depth of needle can not accurately be controlled, in addition, needle end does not have side opening, and is easily blocked, pericardial effusion is extracted in influence, in addition, the tail end sebific duct can be out of shape because of repeatedly sterilizing, and makes syringe be connected not tight with it, cause tube chamber airtight poor, easily make the air admission pericardial cavity, therefore, the paracentesis pericardii pin that uses uses dangerous at present.
Summary of the invention
The purpose of this utility model provides a kind of security performance height, easy to operate and Y centre of form free clothing pricker that airtight performance is strong.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Y centre of form free clothing pricker comprises needle stand, it is characterized in that: needle stand be shaped as " Y " shape, and have three openings, the airtight needle body that is connected with of an end wherein, the needle end of needle body has oblique side opening, the outer wall of needle body has graduation mark; The airtight line that leads that is connected with of the other end of needle stand; The airtight three-way valve that is connected with of the 3rd end of needle stand, the airtight drainage tube that is connected with of a wherein end of three-way valve.
Needle end of the present utility model has side opening, can avoid stopping up, and the pin cornice has graduation mark, can accurately control the degree of depth of inserting needle, and needle stand is provided with three-way valve, can guarantee the seal of tube chamber, and is convenient to extract pericardial effusion, and to pericardium intracavitary administration medicine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing:
1, needle body 2, needle stand 3, line 4, syringe lead
5, drainage tube 6, three-way valve 7, graduation mark 8, syringe needle
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described:
A kind of Y centre of form free clothing pricker as shown in Figure 1, comprises needle stand 2, needle stand 2 be shaped as " Y " shape, and have three openings, the airtight needle body 1 that is connected with of an end wherein, syringe needle 8 ends of needle body 1 have oblique side opening, the outer wall of needle body 1 has graduation mark 7; The airtight line 3 that leads that is connected with of the other end of needle stand 2; The airtight three-way valve 6 that is connected with of the 3rd end of needle stand 2, the airtight drainage tube 5 that is connected with of a wherein end of three-way valve 6.
This utility model adopts the careful free clothing pricker of metal (about 6 centimeter length) to make, about 2 millimeters of the side openings of needle end apart from the top, during use, the puncture needle line (about 1 meter) that leads is connected in the electrocardiogram chest lead electrode, under electrocardiogram monitoring, puncture, when puncture needle was run into the heart adventitia, the S-T section of leading that visible electrocardiogram connects was raised, in the time of can avoiding puncturing like this to the accidental injury of cardiac muscle.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
