Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a medical flow blocker clip. Background Art

[0002] In medical institutions, medical flow blocker clips are commonly used medical devices. Medical flow blocker clips are usually used in cooperation with liquid guide tubes. For example, on the extension liquid guide tube of an indwelling needle, on the liquid guide tube of a drainage bag, on the liquid guide tube for dialysis, etc., so as to achieve the purpose of safe flow blocking. However, due to external forces, the liquid guide tube can swing within the medical flow blocker clip. For example, the patient's limb moves, or the medical staff may also cause the liquid guide tube to swing during rapid operation due to being busy at work. As a result, when clamping, the liquid guide tube is very likely to be displaced within the medical flow blocker clip. If not carefully observed and confirmed, it is easy to cause the situation that the medical flow blocker clip clamps the liquid guide tube unevenly (incompletely), resulting in the technical problem of liquid leakage from the liquid guide tube, bringing certain potential safety hazards to the patient and increasing the probability of medical disputes.

[0003] Therefore, finding a technical solution to solve the above technical problems has become an important research topic for those skilled in the art. Summary of the Utility Model

[0023] The embodiment of the present invention discloses a medical flow blocker clip, which is used to solve the technical problem that the existing liquid guide tube is prone to swing in the medical flow blocker clip under external force, resulting in the phenomenon of often being clamped obliquely during actual clinical use of the medical flow blocker clip, thereby causing the leakage of the liquid guide tube.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the following will further describe the present invention in detail in conjunction with the drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figure 1 , a medical flow blocker clip provided by an embodiment of the present invention includes a fixed section 1 and a pressing section 2 which are connected to each other. Among them, through holes 3 for the liquid guide tube 4 to pass through are provided on both the fixed section 1 and the pressing section 2. A first clamping part 5 is provided on the inner side wall of the fixed section 1, and a second clamping part 6 opposite to the first clamping part 5 is provided on the inner side wall of the pressing section 2. A clamping structure is provided at the free ends of the fixed section 1 and the pressing section 2, and the clamping structure is used to clamp the free end of the pressing section 2 and the free end of the fixed section 1 to fix each other so that the first clamping part 5 and the second clamping part 6 clamp the liquid guide tube 4;

[0026] Limiting parts 7 for restricting the deviation of the liquid guide tube 4 between the first clamping part 5 and the second clamping part 6 are provided on the opposite two side surfaces of the second clamping part 6.

[0027] In the medical flow-blocking clip of this embodiment, limiting portions 7 for restricting the offset of the liquid guide tube 4 between the first clamping portion 5 and the second clamping portion 6 are provided on opposite side surfaces of the first clamping portion 5 and / or opposite side surfaces of the second clamping portion 6. Through the above design, although the liquid guide tube 4 swings under an external force, the above-mentioned limiting portions 7 can effectively restrict the offset movement of the liquid guide tube 4, so that the liquid guide tube 4 can always be clamped by the first clamping portion 5 and the second clamping portion 6, avoiding situations such as liquid leakage and external leakage of the liquid guide tube 4, ensuring the flow-blocking function of the medical flow-blocking clip, and preventing unnecessary accidents from occurring during medical procedures, which may cause harm to patients and unnecessary medical disputes. Moreover, the design of the above-mentioned limiting portions 7 can also relax the diameter limit of the liquid guide tube 4, enabling liquid guide tubes 4 with different diameters to be ensured to be clamped by the medical flow-blocking clip in this embodiment without external leakage.

[0028] Further, the limiting portion 7 in this embodiment is specifically a limiting plate, and the limiting plate is provided on opposite side surfaces of the second clamping portion 6.

[0029] It should be noted that in order to ensure that the limiting plate can play a role in limiting the liquid guide tube 4, it is preferred that the limiting plate can completely cover the second clamping portion 6 and can reach the fixed section 1 when being clamped.

[0030] In addition, in order to enable medical staff to clearly observe the liquid guide tube 4, the limiting plate in this embodiment is preferably made of a colored translucent and elastic material or a PVC material.

[0031] Further, the engaging structure in this embodiment includes a first engaging portion 8 provided at the free end of the fixed section 1 and a second engaging portion 9 provided at the free end of the pressing section 2;

[0032] When the pressing section 2 is pressed and moves closer to the fixed section 1, the first engaging portion 8 and the second engaging portion 9 engage with each other to clamp the liquid guide tube 4 by the first clamping portion 5 and the second clamping portion 6.

[0033] There are various structures for the first engaging portion 8 and the second engaging portion 9 in this embodiment. One of the structures is:

[0034] The first engaging portion 8 in this embodiment is a slot, and the second engaging portion 9 in this embodiment is a hook;

[0035] It should be noted that through the above design, when the pressing section 2 is pressed and moves closer to the fixed section 1, the hook and the slot engage with each other to clamp the liquid guide tube 4 by the first clamping portion 5 and the second clamping portion 6.

[0036] Further, the number of the card slots in this embodiment is multiple, and the multiple card slots are arranged in sequence along the length direction of the free end of the fixed section 1.

[0037] It should be noted that through the above design, medical staff can make the hook snap into the card slots at different positions according to the pipe diameter of the liquid guide pipe 4, so as to meet the clamping requirements of the medical flow stop clip for liquid guide pipes 4 with different pipe diameters.

[0038] In addition, the purpose of designing multiple card slots is to prevent the hook from rebounding due to excessive internal pressure, losing the function of safe clamping, and increasing its safety.

[0039] Further, the fixed section 1 and the pressing section 2 in this embodiment are of an integrally formed structure.

[0040] It should be noted that through the above design, the structural integrity of the medical flow stop clip can be higher. The pressing section 2 and the fixed section 1 are preferably made of slightly elastic plastic or PVC materials. Using slightly elastic plastic materials can ensure that the medical flow stop clip is light in weight and can ensure the elastic deformation of the pressing section 2, so as to meet the requirement that the pressing section 2 and the fixed section 1 are mutually clamped and fixed through the clamping structure.

[0041] Further, the side surface of the first clamping portion 5 facing the second clamping portion 6 in this embodiment is an arc surface, and the side surface of the second clamping portion 6 facing the first clamping portion 5 in this embodiment is an arc surface.

[0042] Further, the outer side wall of the pressing section 2 in this embodiment is provided with anti-slip patterns.

[0043] It should be noted that through the above design, it can prevent the hand from slipping when the medical staff presses the pressing section 2, and it is more convenient for the medical staff to operate the pressing section 2.

[0044] The above has introduced in detail a medical flow stop clip provided by the present invention. For those of ordinary skill in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
