a guide wire 400 is detachably arranged in the guide wire channel 210;
the guide wire channel 210 is communicated with the puncture needle 110 of the puncture part, so that the guide wire 400 sequentially passes through the guide wire channel 210 and the puncture needle 110 to enter a target blood vessel;
in the using process, the target blood vessel position is firstly penetrated through the river puncturing needle 110, namely a large amount of blood gushes out, so that in order to avoid the problem that the blood reversely flows into the guide wire channel 210 through the needle 110 and further causes massive bleeding and runaway, the joint position of the puncturing needle 110 and the guide wire channel 210 is provided with the one-way valve 300;
as shown in fig. 2, the check valve 300 is a structure of an elastic gasket, which blocks the entire passage;
the center of the elastic gasket is provided with a cross scratch, and the guide wire can enter the needle head through the cross scratch under the action of external force; meanwhile, the gasket is made of elastic silicon rubber or medical silicon rubber and the like, so that the gasket has an elastic retraction function, and after the guide wire enters, the channel can be closed due to the elastic retraction characteristic, so that liquid such as blood and the like cannot enter the guide wire channel through the channel;
as shown in fig. 1, in order to realize the purpose of slowly advancing the guide wire into the blood vessel through the needle under the action of non-second manual assistance or other external force, the guide wire part is provided with a groove structure.
In order to realize the purpose of smoothly pushing the guide wire, the groove is just right above the guide wire and can be directly contacted with the guide wire, the lower part of the guide wire is tightly attached to or slightly suspended on the inner surface of the guide wire channel, in the using process, fingers are contacted with the guide wire through the groove, the thumb pushes forwards, and the guide wire is pushed forwards step by step.
In addition, in order to realize the purpose that whether bleeding occurs or not is observed when the needle is punctured in place, the shell 120 of the puncturing part of the outer shell of the device is made of transparent material.
Further, in order to observe the bleeding state, the flow rate, etc., as shown in fig. 3, the end of the needle has a branch tube 111, which extends out of the outer surface of the housing, and the open end of the branch tube has a structure such as a collapsible bulkhead.
Example II,
As shown in fig. 4, the present embodiment provides a guidewire-needle integrated arteriovenous puncture device operable by one hand, comprising a cylindrical puncture device body;
the puncture device body consists of a puncture part 100 and a guide wire part 200;
the puncturing part 100 is a needle tube structure;
the tip of the needle tube structure is a puncture needle head 110;
the puncture needle 110 is a conventional medical needle structure, and a hollow inner tube thereof can accommodate the guide wire 400 to pass through;
the guide wire part 200 has a guide wire channel 210 in the length direction, and is a cylindrical body, the inner diameter of which can be the same as or different from the diameter of the needle inner tube;
a guide wire 400 is detachably arranged in the guide wire channel 210;
the guide wire channel 210 is communicated with the puncture needle 110 of the puncture part, so that the guide wire 400 sequentially passes through the guide wire channel 210 and the puncture needle 110 to enter a target blood vessel;
in the using process, the target blood vessel position is firstly penetrated through the river puncturing needle 110, namely a large amount of blood gushes out, so that in order to avoid the problem that the blood reversely flows into the guide wire channel 210 through the needle 110 and further causes massive bleeding and runaway, the joint position of the puncturing needle 110 and the guide wire channel 210 is provided with the one-way valve 300;
as shown in fig. 2, the check valve 300 is a structure of an elastic gasket, which blocks the entire passage;
the center of the elastic gasket is provided with a cross scratch, and the guide wire can enter the needle head through the cross scratch under the action of external force; meanwhile, the gasket is made of elastic silicon rubber or medical silicon rubber and the like, so that the gasket has an elastic retraction function, and after the guide wire enters, the channel can be closed due to the elastic retraction characteristic, so that liquid such as blood and the like cannot enter the guide wire channel through the channel;
as shown in fig. 3, in order to achieve the purpose of slowly advancing the guide wire into the blood vessel through the needle without the assistance of a second human power or other external force, a pushing mechanism is embedded on the guide wire portion, in this embodiment, the pushing mechanism is a gear 230, and by rolling of the gear 230, the guide wire can move forward or backward in the puncture device body (i.e., in the tube body where the guide wire channel and the needle are communicated).
In order to realize the purpose of smoothly pushing the guide wire, the installation position of the gear 220 is just right above the guide wire, the guide wire is pressed into the guide wire channel, so that the guide wire is bent to a certain radian, and meanwhile, in order to improve the smoothness of advancing of the guide wire, the guide wire channel and the gear are in clearance fit.
In addition, based on the above structure, it is found that when the resistance between the guide wire and the gear is increased, the advancement of the guide wire can be facilitated, and therefore, the gear teeth can be made of an elastic material or plastic.
As shown in fig. 5, the gear is rotatably fixed to the housing 200 by a roller 232, and a spacer 231 is provided between the gear and the inner wall of the housing to prevent the gear from being displaced on the roller.
As shown in figure 4, one end of the gear is tangent to the guide wire, and the other end of the gear protrudes out of the outer surface of the shell, so that the effect of directly stirring by fingers is achieved.
In addition, in order to realize the purpose of preventing the device from slipping off randomly in the holding state, the surface of the outer casing of the device is provided with an uneven hand-shaped holding structure 220.
In addition, in order to realize the purpose that whether bleeding occurs or not is observed when the needle is punctured in place, the shell 120 of the puncturing part of the outer shell of the device is made of transparent material.
Further, in order to observe the bleeding state, the flow rate, etc., as shown in fig. 6, the needle has a branch tube 111 at the end, which extends out of the outer surface of the housing, and the open end of the branch tube has a structure such as a collapsible bulkhead.
