Description

Technical Field

[0001] This utility model relates to the field of arteriovenous fistula puncture technology, specifically to an arteriovenous fistula puncture device that can be located based on puncture maps. Background Technology

[0002] Arteriovenous fistula (AVF) is a surgical procedure primarily used for hemodialysis. AVF surgery is a minor surgical procedure involving the anastomosis of an artery and a nearby vein in the forearm near the wrist, allowing arterial blood to flow through the anastomosed vein, thus forming an AVF. The AVF provides sufficient blood for hemodialysis, ensuring the adequacy of the treatment.

[0003] With the development of hemodialysis technology, more and more attention is being paid to patients' arteriovenous fistulas. Drawing an arteriovenous fistula diagram can ensure that the patient's arteriovenous fistula has the opportunity to be accurately punctured. Traditionally, arteriovenous fistula diagrams are drawn manually by medical staff using measuring tools such as tape measures and rulers during puncture. These measuring devices are inconvenient to hold and fix, which affects the user's ability to draw the arteriovenous fistula diagram during measurement.

[0004] Therefore, it does not meet the existing needs, so we propose an internal atrophy puncture device that can be located based on puncture maps. Utility Model Content

[0005] The purpose of this invention is to provide an internal atrophy puncture device that can be located based on a puncture map, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an internal atrophy puncture device that can be located based on a puncture map, comprising: a measuring ruler body, a finger ring provided at one end of the measuring ruler body, a finger hole provided at the middle position of the finger ring, a plurality of horizontally spaced scale bars provided on the outer wall of the front end face of the measuring ruler body, and a transparent drawing plate rotatably provided above the measuring ruler body, with the transparent drawing plate facing directly above the scale bars.

[0007] Preferably, an assembly port is provided at the middle position above the main body of the measuring ruler, and the inner walls at both ends of the assembly port are provided with a rotating shaft for rotating the transparent drawing plate.

[0008] Preferably, a locking block is provided at one end of the rotating shaft near the transparent drawing board, and slots are provided at both ends of the bottom of the transparent drawing board, and the slots engage with the locking block.

[0009] Preferably, the bottom of the card slot has an opening, and the diameter of the opening is smaller than the diameter of the card slot.

[0010] Preferably, the card block is a plastic card that deforms when passing through the opening to complete the entry and exit operation.

[0011] Preferably, a protruding limiting handle is provided between the ring and the measuring ruler body, and the limiting handle, the ring and the measuring ruler body are all integral structures.

[0012] Preferably, the position handle and the measuring ruler body form a side L-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model modifies the structure of the measuring ruler by using a finger ring and finger hole for easy attachment and gripping by the user. Furthermore, since different nurses may have different measurement methods, the thumb attachment method allows for a relatively consistent standard for different nurses. The transparent drawing board allows users to draw arteriovenous fistula puncture diagrams on it with a marker. The scale strips on the main body of the measuring ruler facilitate accurate positioning of distances between puncture points, distances from puncture points to arteriovenous fistulas, and distances between arteriovenous puncture points, etc., making measurement and drawing convenient for users.

[0015] 2. The transparent drawing board can be rotated via a pivot. In addition, the structure is detachable through the design of blocks and slots, making it easy for users to disassemble and remove. The overall operation is simple and easy for users to learn. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1This utility model provides an embodiment of an internal atrophy puncture device that can locate the affected area based on a puncture map. The device includes: a measuring ruler body 1; a finger ring 3 at one end of the measuring ruler body 1; a finger hole 4 at the middle of the finger ring 3; several horizontally spaced scale bars 5 on the outer wall of the front face of the measuring ruler body 1; and a transparent drawing plate 9 rotatably mounted above the measuring ruler body 1, with the transparent drawing plate 9 facing the top of the scale bars 5. The finger ring 3 and finger hole 4 allow the user to easily insert their thumb into the device, facilitating fixation and gripping. Since different nurses may have different measurements, the thumb loop design allows for a relatively consistent standard for different nurses. The transparent drawing board 9 is used to allow users to draw arteriovenous fistula puncture diagrams on it with a marker. The scale strip 5 on the main body of the measuring ruler 1 allows users to accurately locate the distance between puncture points, the distance between the puncture point and the arteriovenous fistula, and the distance between the arteriovenous puncture points, etc., making it convenient for users to measure and draw. After drawing, the scale strip can be lifted by rotating it, allowing users to easily refer to the location for disinfection and puncture.

[0023] Please see Figure 2 , Figure 3 , Figure 4 An assembly port 6 is provided at the middle position of the upper part of the measuring ruler body 1. A rotating shaft 7 for rotating the transparent drawing plate 9 is provided on the inner wall of both ends of the assembly port 6. A locking block 8 is provided at the end of the rotating shaft 7 near the transparent drawing plate 9. A slot 10 is provided at both ends of the bottom of the transparent drawing plate 9, and the slot 10 engages with the locking block 8. An opening 11 is provided at the bottom of the slot 10, and the diameter of the opening 11 is smaller than the diameter of the slot 10. Furthermore, the locking block 8 is a plastic locking component that deforms when passing through the opening 11 to complete the insertion and exit operation. The rotating shaft 7 is used to... The transparent drawing board 9 rotates, and the locking block 8 rotates with the rotating shaft 7. During installation, the locking block 8 is inserted upward from the opening 11 into the slot 10, so that when the rotating shaft 7 rotates, it can drive the transparent drawing board 9 to rotate. At the same time, the transparent drawing board 9 is detachable. The locking block 8 can be disassembled from the opening 11 by prying it up and down, and the transparent drawing board 9 can be removed. The transparent drawing board 9 allows users to easily observe the user's hand and allows users to draw with markers. It can also be erased and reused later.

[0024] Please see Figure 1A protruding limiting handle 2 is provided between the ring 3 and the main body 1 of the measuring ruler. The limiting handle 2, the ring 3 and the main body 1 of the measuring ruler are all integral structures. Furthermore, the limiting handle 2 and the main body 1 of the measuring ruler form a side L-shaped structure. After the thumb is inserted into the finger hole 4, the ring 3 can play a limiting role, making it difficult to slip out of the hand and convenient for the user to grip and use. Since the limiting handle 2 is protruding and has a lying L-shaped structure, the limiting handle 2 can assist the hand in gripping operation after the user puts it on, making it more convenient to use than a traditional ruler.

[0025] Working principle: During use, the user can easily insert their thumb into the ring 3 and finger hole 4 for easy fixation and gripping. After the thumb is inserted into the finger hole 4, the ring 3 restricts the thumb, making it difficult to slip out of the hand and facilitating gripping. The limiting handle 2 is a raised, L-shaped structure, which assists in hand gripping after being fitted, making it more convenient than traditional rulers. Furthermore, since different nurses may have different measurements, the thumb insertion method provides a relatively consistent standard for different nurses. The transparent drawing plate 9 allows the user to draw fistula puncture diagrams with a marker. The scale strip 5 on the main body 1 of the measuring ruler allows the user to accurately locate the distance between puncture points, the distance from the puncture point to the fistula, and the distance between arteriovenous puncture points, facilitating measurement and drawing. After drawing, the scale strip can be flipped up for the user to refer to for disinfection and puncture.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
