Abstract
The utility model provides a new type pericardial puncturing needle assembly, comprising a puncturing needle (1) made of metal passing through a side arm sheath (2). The inner cavity of the base of the side arm sheath is communicated with the hose of a triple valve (5), and the other end of the triple valve is connected with a sphere switch (6) in the single direction and is connected with a drainage bag (7) with a drainage switch through the hose. The side arm sheath (2) is a puncturing sleeve tube made from macromolecule material with stronger memory, and the front part of the puncturing sleeve tube is in arc bending shape. The damage of cardiac muscle is avoided, and drainage effusion can be sufficiently utilized. The sphere switch (6) in the single direction can adjust the speed of the drainage effusion, and the quantity of the drain effusion is measured by the drainage bag (7) of the drainage switch with scales.
Description
Technical field
This utility model provides a kind of medical apparatus and instruments, specifically is used for the novel paracentesis pericardii pin of pericardial effusion drain.
Background technology
Traditional paracentesis pericardii is directly to be carried out by the different model draw point, and the head of draw point is sharp sharp, no matter is when puncture or during the pericardial effusion drain, heart is constantly beated, and hydrops reduces, all may injury of myocardium or scratch coronary artery, cause cardiac event; Patient especially carcinous for large pericardial effusion in addition or tuberculosis sexual needs constant drainage or medicine injection treatment can not carry out; Moreover can not avoid cross infection.
Summary of the invention
The purpose of this utility model is: overcome the deficiency of above technology, a kind of new-type paracentesis pericardii pin is provided, it not only can avoid the hard metal puncture pin injury of myocardium of point to cause cardiac event, again abundant drain hydrops.
The technical solution of the utility model is: this novel paracentesis pericardii needle assembly mainly is made up of the drainage bag of side arm sheath, piercing needle, haemostatic valve, three-way valve, unidirectional ball type switch, band drain switch, it is characterized in that: the needle body with metal puncture needle passes through haemostatic valve, enter the side arm sheath, the needle body of puncture needle slightly is longer than the side arm sheath, the base intracavity of side arm sheath communicates with the flexible pipe that its side arm has three-way valve, the three-way valve other end connects unidirectional ball type switch, links the drainage bag of band drain switch again by flexible pipe.The sheath pipe of side arm sheath is the thin tube-like puncture casing of being made by the stronger macromolecular material of a kind of Memorability, and at the anterior camber bending of puncture casing, there is 2-3 side opening on the surface.The three-way valve far-end has control to drip fast unidirectional ball type switch, and drainage bag indicates scale.
This utility model paracentesis pericardii needle assembly has the following advantages: (1) side arm sheath is certain bending curvature because of itself material after having pliability and entering pericardium, effectively avoided the direct malpractice that causes with the puncture needle drawing liquid, abundant drain hydrops again, do simultaneously lasting the indwelling as required, and can avoid the sheath pipe to deviate from.(2) can directly extract hydrops or inject medicine with syringe by three-way valve device.(3) adjust drain hydrops speed by unidirectional ball type switch, calculate drain hydrops amount by the drainage bag that has scale drain switch, avoid too fast drain to cause the pericardium pressure drop to cause pulmonary edema, this drainage way has been avoided cross infection simultaneously.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the sheath tubular construction sketch map of this utility model side arm sheath;
Fig. 3 is the structural representation of this utility model piercing needle.
Among the figure: drainage bag, 8 puncture needle bending sections, 9 side openings of 1 piercing needle, 2 side arm sheaths, 3 haemostatic valve, 4 syringes, 5 three-way valve, 6 unidirectional ball type switch, 7 band drain switches.
The specific embodiment
This utility model paracentesis pericardii needle assembly is made up of the drainage bag (7) of side arm sheath (2), piercing needle (1), haemostatic valve (3), three-way valve (5), unidirectional ball type switch (6), band drain switch.Needle body with metal puncture needle passes through haemostatic valve, enter side arm sheath (2), the needle body of puncture needle slightly is longer than side arm sheath (2), the base intracavity of side arm sheath communicates with the flexible pipe that its side arm has three-way valve (5), three-way valve (5) other end connects unidirectional ball type switch (6), indicates graduated drainage bag (7) by what flexible pipe was linked band drain switch again.During use, preparation and point of puncture are selected identical with traditional method before the art of this utility model paracentesis pericardii pin.Under the B ultrasonic location, with thick needle point of puncture repeatedly prick skin to corium, puncture needle is stabbed pericardium lentamente, have when needle point passes pericardium parietale and break through sense, at this moment, hydrops can be attracted owing to the suction function of syringe, fixedly puncture needle is slowly sent into side arm sheath (2) 3cm-4cm, extract piercing needle, side arm sheath (2) reverts to the arc-shaped bend shape by flat after entering pericardium, and can be as required, adjust angle, the base intracavity of side arm sheath communicates with the flexible pipe that its side arm has three-way valve (5), and three-way valve (5) other end connects unidirectional ball type switch (6), opens gauge tap, adjust the hydrops flow velocity, avoid drain too fast,, also can extract hydrops out or inject medicine by three-way valve (5) with injection syringe (4) by drainage bag (7) the calculated product liquid measure of band drain switch.
Claims (3)
1. novel paracentesis pericardii needle assembly, mainly by piercing needle (1), side arm sheath (2), haemostatic valve (3), three-way valve (5), unidirectional ball type switch (6), the drainage bag (7) of band drain switch is formed, and it is characterized in that:
A. the needle body with metal puncture needle enters side arm sheath (2) by haemostatic valve (3), and the needle body of puncture needle slightly is longer than side arm sheath (2), and the needle stand and the syringe of puncture needle are connected.
B. the base intracavity of side arm sheath (2) communicates with the flexible pipe that its side arm has three-way valve, and three-way valve (5) other end connects unidirectional ball type switch (6), links the drainage bag (7) of band drain switch again.
2. novel paracentesis pericardii needle assembly according to claim 1, it is characterized in that: the sheath pipe of side arm sheath (2) is the thin tube-like puncture casing of being made by the stronger macromolecular material of a kind of Memorability, the shape (8) that is convexly curved in the front portion of puncture casing, there is 2-3 side opening (9) on the surface.
3. novel paracentesis pericardii needle assembly according to claim 1 is characterized in that: three-way valve (5) far-end has control to drip fast unidirectional ball type switch (6), and the drainage bag (7) of band drain switch indicates scale.
