Description

An arteriovenous fistula thrombolytic needle

technical field

The utility model is suitable for the field of medical technology, in particular to an arteriovenous internal fistula thrombolysis needle.

Background technique

At present, thrombus refers to the coagulation of blood or the coagulation of some formed components in the blood to form a solid mass in the heart and blood vessels of the living body. Under normal circumstances, it can play the role of local coagulation and hemostasis, but sometimes the coagulation process is abnormally triggered, resulting in thrombosis.

In the prior art, when the arteriovenous fistula thrombolytic needle is used, the following problems are prone to occur. First, the needle needs to be inserted into the skin blood vessel, and then the thrombus is extracted through the syringe. After extraction, the syringe needs to be separated from the needle, and the needle needs to be pre-treated. Left in the skin, when the syringe is separated, the blood in the needle tube will overflow at this time, and the prior art does not have a needle tube locking mechanism. When the syringe is separated from the retained needle, the blood will easily overflow, which will greatly cause inconvenience during use. In order to solve the above problems, we propose a thrombolytic needle for arteriovenous fistula.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

An arteriovenous fistula thrombolysis needle, comprising a butt tube, a clip shell is connected to the right end of the butt tube, a needle hole is opened in the clip shell, and a needle tube is built in the needle hole, and the clip shell is The outer wall is provided with a threaded groove, and a butterfly bolt is built in the threaded groove, and the butted tube is communicated with the needle hose.

Preferably, the thread groove communicates with the inner wall of the pinhole.

Preferably, the thread groove is adapted to the thread size of the butterfly bolt, and the end of the butterfly bolt is attached to the outer wall of the needle tube.

Preferably, the end of the butterfly bolt is hemispherical.

Preferably, the outer wall of the needle tube is provided with a scale bar.

Preferably, the needle tube is 6 cm.

Compared with the prior art, the beneficial effects of the present utility model are:

1. In the present utility model, the needle hose is located in the needle hole opened in the clamp case, and the clamp case is provided with a clamp mechanism. Before the syringe is separated from the butt tube, the clamp mechanism can form a locking clamp on the needle hose. Therefore, it can prevent the blood from spilling out of the body, thereby greatly improving the convenience effect when using it.

2. The utility model is provided with a scale bar on the needle tube, which will facilitate precise control of the insertion depth of the needle tube, and is convenient for medical staff to use.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inside", The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation , are constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

In the description of the present utility model, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "arrangement" should be understood in a broad sense, for example, it may be fixedly connected, arranged, or It is a detachable connection, setting, or an integral connection and setting; the model of the electrical appliance provided in this utility model is only for reference, and it is possible to replace different types of electrical appliances with the same function according to the actual use situation. In other words, the specific meanings of the above terms in the present invention can be understood in specific situations.

1-2, an arteriovenous fistula thrombolysis needle, including a butt tube 1, the right end of the butt tube 1 is connected with a clip shell 4, the inside of the clip shell 4 is provided with a needle hole 7, and the needle hole 7. A needle tube 2 is built in, a threaded groove 5 is formed on the outer wall of the clamping shell 4, and a butterfly bolt 6 is built in the threaded groove 5. The right end of the butt tube 1 is communicated with the left end of the needle tube 2, and the The butt tube 1 is made of rubber material. In this embodiment, the needle tube 2 is located in the needle hole 7 opened in the clamp shell 4, and the clamp shell 4 is provided with a clamp mechanism. Before the syringe and the butt tube 1 are separated, The clamping mechanism can form a locking and clamping effect on the needle tube 2, so as to avoid blood spillage in the body, thereby greatly improving the convenience effect during use.

In this embodiment, the thread groove 5 communicates with the inner wall of the needle hole 7, and the thread groove 5 communicates with the inner wall of the needle hole 7. When the butterfly bolt 6 rotates in the thread groove 5, the butterfly bolt 6 can enter The inside of the needle hole 7 is in contact with the outer wall of the needle soft 2 tube.

In this embodiment, the thread groove 5 is adapted to the thread size of the butterfly bolt 6, and the end of the butterfly bolt 6 is fitted to the outer wall of the needle tube 2, and the thread groove 5 is adapted to the thread size of the butterfly bolt 6. When the butterfly bolt 6 is rotated, the end of the butterfly bolt 6 will be squeezed against the outer wall of the needle tube 2. At this time, the needle tube 2 will be pressed to form a blockage, thereby closing the needle tube 2 to prevent blood Move out.

In this embodiment, the end of the butterfly bolt 6 is hemispherical, and the end of the butterfly bolt is hemispherical. When the end of the butterfly bolt 6 is in contact with the needle tube 2, the spherical end will protect the outer wall of the needle tube 2 , to avoid damage to the needle tube 2 during the process.

In this embodiment, the outer wall of the needle tube 2 is provided with a scale bar 3, and the outer wall of the needle tube 2 is provided with a scale bar 3. When the needle tube 2 is inserted into the skin, it is convenient for medical staff to check the needle tube. 2 The depth of insertion into the body forms precise control.

In this embodiment, the needle tube 2 is 6 cm.

When the utility model is used: the needle tube 2 will be implanted in the body, and the thrombus in the blood vessel will be extracted by the external syringe of the connecting tube 1. Since all thrombus is not extracted at one time, when the syringe needs to be replaced, the butterfly bolt 6 is first rotated to make the butterfly The bolt 6 rotates in the threaded groove 5, at this time the butterfly bolt 6 rotates and moves in the threaded groove 5, the end of the butterfly bolt 6 will move close to the needle tube 2, and finally the end of the butterfly bolt 6 will be squeezed on the needle tube 2. The outer wall forms a clamping lock for the needle tube 2, so that the needle tube forms a closed state, prevents the blood from overflowing from the butt tube 1, and ensures the blocking of excess blood when the butt tube 1 is separated from the extractor, while the outer wall of the needle tube 2 The set scale bar 3 will help to accurately know the depth of the implantation of the needle tube 2 into the body, which is convenient for medical staff to accurately control and use, and improves the convenience of use. The design is simple and practical.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
