Technical Field

[0001] This utility model relates to the field of venous guidewire insertion tools, and more specifically to an auxiliary device for deep vein puncture and catheter placement guidewire. Background Technology

[0002] Central venous catheterization is an indispensable procedure in intensive care units, major surgeries, and the treatment of critically ill patients. It involves inserting a catheter into a central venous vein through a puncture site on the body surface. The central venous catheter is the core instrument used in this procedure.

[0003] Based on the published Chinese patent, publication number CN108577946A, publication date 2018-09-28, a method for deep vein catheterization via the external jugular vein is disclosed. It is known that the device includes a guidewire holder and a guidewire. During operation, the puncture depth is estimated, and the guidewire holder (a diaphragm is a medical device used to dilate the puncture channel to facilitate the smooth entry of the deep vein catheter) is inserted along the guidewire and then withdrawn.

[0004] In existing technologies, including the aforementioned patents, the common procedure for deep vein puncture is to push the exposed guidewire from the coil using the pad of the thumb while wearing a glove. However, nurses need to wear disposable medical gloves during the procedure, which reduces friction between the fingers and the guidewire, making the actual guidewire pushing operation rather inconvenient.

The guidewire frame includes a horizontal portion, and the guidewire passing through the guidewire frame has an exposed section of a predetermined length at the horizontal portion. It also includes an elastic element and a movable portion that cooperates with the elastic element.

[0008] With reference to the direction of movement of the guidewire, one end of the horizontal section is the starting end and the other end is the ending end;

[0009] The movable part is slidably disposed on the horizontal part and held in place by the elastic element under the action of the elastic element, which drives the movable part to remain at the starting end.

[0010] Preferably, a bracket is fixedly installed at the bottom of the guide wire frame, and a guide rod that moves in the same direction as the guide wire is fixedly installed inside the bracket;

[0011] The moving part includes a sliding part that slides on the guide rod.

[0012] Preferably, the moving part and the sliding part are connected as one unit by a connecting rod, and the wire guide frame is provided with a sliding groove for the connecting rod to move, and the sliding groove is in communication with the interior of the bracket.

[0013] Preferably, the elastic element is an equidistant spring, which is sleeved on the guide rod.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, a deep vein puncture and catheterization guidewire auxiliary device includes a guidewire frame 1 and a guidewire 2. The guidewire frame 1 includes a horizontal part 3, and the guidewire 2, which is inserted on the guidewire frame 1, has an exposed section of a predetermined length at the horizontal part 3. It also includes an elastic element 7 and a movable part 4 that cooperates with the elastic element 7.

[0025] With reference to the direction of movement of guide wire 2, one end of the horizontal part 3 is the starting end and the other end is the ending end;

[0026] The movable part 4 is slidably disposed on the horizontal part 3 and is held in place by the elastic member 7 under the action of the elastic member 7 to drive the movable part 4 to remain at the starting end.

[0027] Specifically, the elastic element 7 in the embodiment can be a retaining spring or a tension spring, which, in conjunction with the moving part 4, provides damping force.

[0028] The sliding part 4 is used to reduce the damping effect caused by the fingertip pressing against the guide wire 2, so that the guide wire 2 can still be pushed even after wearing disposable medical gloves.

[0029] In the above embodiment, the nurse presses the exposed section on the moving part 4 with her fingertip, and then pushes it from the starting end to the ending end. When she releases the pressed exposed section, the moving part 4 returns to the starting end under the elastic drive of the elastic member 7 returning to its default state. This process is repeated to achieve the wire feeding operation of the guidewire 2.

[0030] As a further embodiment of this utility model, combined with Figure 3 As shown, a bracket 5 is fixedly installed at the bottom of the guide wire holder 1, and a guide rod 51 with the same moving direction as the guide wire 2 is fixedly installed inside the bracket 5;

[0031] The moving part 4 includes a sliding part 41, which slides on the guide rod 51.

[0032] The elastic element 7 is an equidistant spring, which is sleeved on the guide rod 51.

[0033] Specifically, in the embodiment, the bracket 5, the wire guide 1, and the groove on the wire guide 1 for the movable part 4 to move are all integrally formed during casting. The sliding direction of the sliding part 41 is provided by the guide rod 51, while the equidistant spring is restricted by the guide rod 51, thereby contracting and extending in the axial direction under the pushing pressure of the sliding part 41.

[0034] As another embodiment further provided by this utility model, combined with Figure 2 and Figure 3 As shown, the moving part 4 and the sliding part 41 are connected as one unit by the connecting rod 42. The guide wire frame 1 is provided with a sliding groove for the connecting rod 42 to move, and the sliding groove is connected to the inside of the bracket 5.

[0035] Specifically, in the embodiment, the connecting rod 42 slides within the groove.

[0036] As another embodiment further provided by this utility model, combined with Figure 2 and Figure 3 As shown, a flexible clip 6 with an 8-shaped outline is fixedly installed on the moving part 4, and perforations with a circumferential radius larger than that of the guide wire 2 are opened on the outer walls of opposite sides of the flexible clip 6. The flexible clip 6 is a polyethylene elastic plastic part.

[0037] Specifically, in the embodiment, when the fingertip presses the elastic clip 6, the elastic clip 6 is compressed and deformed, that is, the two circular outlines of the figure 8 become elliptical, thereby pressing the guide wire 2. Then, it is pushed from the starting end to the ending end. At this time, the exposed section of the pressing is released, and the moving part 4 is driven back to the starting end by the elasticity of the elastic member 7 returning to its default state. This process is repeated to realize the wire feeding operation of the guide wire 2.

[0038] It should be noted that the aforementioned fixed installations and joints can be installed using known connection methods such as welding, bolting, or snap-fitting; while rotating installations and hinged joints are installed using rotary bearings, and sliding installations are installed using sliding bearings. These installation methods are all common knowledge to those skilled in the art, and can be directly determined by those skilled in the art based on the structural characteristics; therefore, they will not be described in detail.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
