Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically to a flow-blocking clip. Background Technology

[0002] In modern medicine, intravenous infusion is a very common and important treatment method. During the infusion process, it is sometimes necessary to precisely control the flow of the fluid, which requires a device to control the flow of the infusion tubing.

[0003] Patent publication number CN205841847U discloses a clamp that provides a solution for blocking intravenous infusion tubes. This clamp is designed with a receiving groove specifically for accommodating the infusion tube and a blocking groove for compressing and blocking the flow of fluid, with the width of the blocking groove being smaller than the width of the receiving groove. Its working principle is that when blocking is required, medical personnel manually pull the infusion tube into the blocking groove. The structure of the blocking groove compresses and closes the lumen of the infusion tube, thereby preventing the fluid from passing through.

[0004] However, this existing technology reveals significant inconvenience and potential risks in practical operation. Medical staff must directly handle the infusion tubing with their hands before pulling it into the closure chamber. On the one hand, the medical environment demands strict aseptic technique, and direct contact between hands and the infusion tubing greatly increases the chance of contamination, potentially transferring bacteria, viruses, and other pathogens to the tubing and threatening the patient's health and safety. On the other hand, in emergency situations or when medical staff are busy, manually handling the infusion tubing and precisely maneuvering it into the closure chamber is not only time-consuming but also prone to errors due to haste, affecting the smooth progress of intravenous therapy. Therefore, how to efficiently and safely pull the infusion tubing into the closure state without direct hand contact has become a critical problem that urgently needs to be solved, pointing the way for the development of new closure clips. Summary of the Invention

[0005] In view of the problems pointed out in the background art, this utility model proposes a flow-blocking clip to solve the above-mentioned technical problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A flow-blocking clamp includes a clamp body with a receiving groove and a flow-blocking groove on the clamp body. The flow-blocking groove is elongated and one end is connected to the receiving groove. The width of the flow-blocking groove is smaller than the width of the receiving groove.

[0008] The intercepting channel is provided with connecting channels on both sides of the intercepting channel. The connecting channels extend along the length of the intercepting channel, and one end of the connecting channel extends to communicate with the receiving channel.

[0009] The clip body has two through holes that correspond to the two connecting slots respectively. One end of the through hole is connected to the other end of the connecting slot, and the other end of the through hole passes through one side of the clip body.

[0010] It also includes an annular pull ring connected in two connecting grooves, passing through two through holes, with one end of the pull ring located in the receiving groove and the other end located on the outside of the clip body.

[0011] The present invention is further configured such that the perforation and the corresponding connecting groove are located on the same straight line.

[0012] The present invention is further configured such that both the clip body and the pull ring are made of plastic.

[0013] The present invention is further configured such that one end of the pull ring can undergo an inward bending deformation.

[0014] The present invention is further configured such that the receiving groove is circular, and the width of the connection between the receiving groove and the intercepting groove gradually decreases.

[0015] The present invention is further configured such that the clip body is a near-rectangular thin plate structure.

[0016] The present invention is further configured such that the pull ring is made of a rope.

[0017] The present invention is further provided that the two sides of the clip body in the thickness direction are respectively provided with textured structures for increasing friction.

[0018] The present invention is further provided in that protruding limiting protrusions are respectively provided on the two side walls of the intercepting channel, and the limiting protrusions on the two side walls of the intercepting channel are correspondingly provided.

[0019] The present invention is further configured such that multiple limiting protrusions are provided on both sides of the intercepting channel, and the limiting protrusions on the same side are spaced apart in the length direction of the intercepting channel.

[0020] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0021] Firstly, in terms of structural design, the receiving groove is circular, which provides uniform support for the infusion tubing, greatly reducing the risk of tubing wall damage, ensuring the physical integrity of the tubing, and guaranteeing good infusion performance. Simultaneously, it has a high degree of compatibility with common infusion tubing shapes, fitting naturally and reducing swaying and displacement. Medical staff do not need to make excessive adjustments to the tubing position, saving operation time and improving interception efficiency. The width of the connection between the receiving groove and the interception groove gradually changes, serving both guiding and buffering functions. This precisely guides the infusion tubing into the interception groove, avoiding problems such as tubing twisting and rupture caused by sudden compression, ensuring reliable interception effect.

[0022] Secondly, pull rings can be made of various materials, including plastic or rope. Ropes are soft and comfortable for medical staff to pull, reducing hand fatigue, and are especially suitable for prolonged and frequent operations. Their flexibility also allows the pull ring to fit snugly against the outer wall of the infusion tubing, flexibly adapting to irregular deformations and ensuring smooth flow control. Furthermore, ropes are inexpensive, facilitating large-scale production and promoting the widespread use of flow control clips.

[0023] Furthermore, the clip body has textured structures on both sides along its thickness to increase friction. When medical staff hold the clip, this effectively increases the friction between their fingers and the clip, preventing slippage. Even under adverse conditions such as sweaty hands or continuous operation of multiple clips, the interception task can still be completed accurately and efficiently, ensuring a smooth infusion process.

[0024] Finally, corresponding and spaced-apart restrictive protrusions are provided on both sides of the interception channel, which are like sturdy "barriers" to effectively prevent the infusion tube from accidentally moving back into the receiving tank due to external interference, ensuring the stability of interception and allowing the infusion process to proceed safely as planned.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] For reference as follows Figures 1-4 The present invention will be described as follows:

[0033] Example: A flow-stopping clip includes a clip body 1, which is a near-rectangular thin plate structure. This shape design not only conforms to general operating habits and is easy for medical staff to hold, but also makes reasonable use of space and can compactly arrange various functional structures.

[0034] The clamp body 1 is equipped with a receiving groove 2 and a flow-blocking groove 3, which work together to achieve the flow-blocking function. The flow-blocking groove 3 is elongated, with one end connected to the receiving groove 2. This connection design provides a path for the infusion tube to transition from the conventionally placed receiving groove 2 to the flow-blocking groove 3 in its flow-blocking working state. The width of the flow-blocking groove 3 is smaller than the width of the receiving groove 2. As a result, when the infusion tube moves from the relatively spacious receiving groove 2 into the narrower flow-blocking groove 3, the lumen of the infusion tube is effectively squeezed and closed due to the sudden tightening of space, thereby effectively preventing the liquid from passing through and achieving the purpose of flow blocking.

[0035] Connecting grooves 4 are provided on both sides of the intercepting groove 3. The connecting grooves 4 extend along the length of the intercepting groove 3, and one end of the connecting groove 4 extends to communicate with the receiving groove 2. This design detail is of great significance. It provides precise track support for the subsequent installation and linkage of the pull ring 6, ensuring that the pull ring 6 can run stably along the predetermined route during the pulling process and accurately act on the infusion tube.

[0036] The clip body 1 has two through holes 5 corresponding to the two connecting slots 4 respectively. One end of the through hole 5 is connected to the other end of the connecting slot 4, and the other end of the through hole 5 passes through one side of the clip body 1. The through holes 5 and the corresponding connecting slots 4 are on the same straight line. This strict linear correspondence ensures the smoothness of the pull ring 6 during insertion, avoids jamming or twisting, and allows the pull ring 6 to function stably in the internal structure of the clip body 1.

[0037] It also includes an annular pull ring 6, which is connected in two connecting grooves 4 and passes through two through holes 5. One end of the pull ring 6 is located in the receiving groove 2, and the other end of the pull ring 6 is located outside the clip body 1.

[0038] The connecting groove 4 is used to connect the pull ring 6. The infusion tube is located inside one end of the pull ring 6. Pulling the pull ring 6 from the other end of the pull ring 6 pulls the infusion tube from the receiving groove 2 into the intercepting groove 3. The connecting groove 4 acts as a dedicated guide rail for the pull ring 6, with the infusion tube positioned inside the pull ring 6 at the receiving groove 2 end. In actual operation, medical staff can hold the clip body 1 firmly with their left hand and conveniently pull one end of the pull ring 6 located outside the clip body 1 with their right hand. When the pull ring 6 moves under force, due to its relative position to the infusion tube and the guiding constraints of the connecting groove 4 and the perforation 5, the pull ring 6 can smoothly pull the infusion tube from the receiving groove 2 into the intercepting groove 3. In this way, medical staff do not need to frequently touch or handle the infusion tube directly with their hands during the entire operation process, greatly reducing the risk of infusion tube contamination, while improving the efficiency and accuracy of the interception operation and optimizing the working mode of infusion tube interception.

[0039] Both the clip body 1 and the pull ring 6 are made of plastic. Plastic is lightweight, which makes it less likely for medical staff to experience excessive hand fatigue during prolonged hand operation, allowing them to flexibly and stably control the clip to complete the interception task.

[0040] One end of the pull ring 6 can bend inward. This unique property adds more convenience and reliability to the cut-off operation. When the medical staff pulls the end of the pull ring 6 located outside the clip body 1 with their right hand, the pull ring 6 is subjected to force, and the end located in the receiving groove 2 can flexibly bend inward according to the actual position and state of the infusion tube.

[0041] In its initial state, the infusion tubing is placed in the receiving tank 2, with one end of the pull ring 6 naturally extended, not obstructing the normal placement of the tubing. However, once the pull ring 6 is pulled to initiate the flow-stopping operation, if the infusion tubing deviates slightly or is not fully aligned with the inlet of the flow-stopping tank 3, the deformable pull ring 6 can adaptively bend, tightly conforming to the outer wall of the infusion tubing, precisely and gently holding it in place. Then, guided by the guiding system constructed from the connecting groove 4 and the perforation 5, the infusion tubing is smoothly pulled from the receiving tank 2 into the flow-stopping tank 3. This deformation capability effectively compensates for potential problems caused by inaccurate manual placement of the infusion tubing, further improving the success rate of the flow-stopping operation. This ensures that each pull of the pull ring 6 reliably achieves flow-stopping of the infusion tubing, reducing the occurrence of liquid leakage or incomplete flow-stopping due to operational errors.

[0042] The receiving groove 2 is circular, a shape chosen for several reasons. The circular structure provides more even support for the infusion tubing. Compared to other shapes, the circle has no sharp edges, ensuring uniform stress on the tubing wall when placed within it. This prevents localized excessive pressure, minimizing the risk of damage to the tubing, protecting its physical integrity, and ensuring optimal infusion performance during subsequent use.

[0043] The width of the connection between the receiving tank 2 and the intercepting tank 3 gradually decreases. From the perspective of the flow path of the infusion tube, when the infusion tube needs to transition from the receiving tank 2 to the intercepting tank 3, this gradually narrowing structure plays a dual role of guiding and buffering.

[0044] In terms of guidance, the gradually narrowing width acts like a precise guide rail, naturally "guiding" the infusion tube towards the interception groove 3. Even if medical staff make some deviations when placing the infusion tube, the tube can gradually adjust its position after entering the connection point, following the trend of the width change, and accurately align itself with the inlet of the interception groove 3, greatly improving the convenience and accuracy of the interception operation.

[0045] From a buffering perspective, compared to sudden width changes, the gradual design avoids the infusion tubing encountering significant resistance instantaneously. The infusion tubing can smoothly transition from the relatively spacious receiving groove 2 to the narrower intercepting groove 3, reducing the risk of tubing twisting, bending, or even breakage due to sudden compression. This not only protects the infusion tubing but also ensures a more stable flow state of the liquid before interception. If interception is necessary, it ensures the reliability of the interception effect, preventing liquid leakage or incomplete interception due to abnormal tubing deformation, thus providing a solid guarantee for precise interception during medical infusion.

[0046] Pull ring 6 can also be made of cord. In addition to plastic, pull ring 6 can also be made of cord. Cord has unique advantages. First, cord is usually softer, and the tactile sensation when medical staff pull pull ring 6 is more comfortable, which can effectively reduce hand fatigue, especially when operating the shunt clip for a long time and frequently.

[0047] Secondly, the flexibility of the rope further enhances the deformation capability of the pull ring 6 during the pulling process. When it is necessary to pull the infusion tube from the receiving tank 2 into the intercepting tank 3, the pull ring 6 made of the rope can better fit the shape of the outer wall of the infusion tube. Even if the infusion tube has a certain curvature or irregular deformation, the pull ring 6 can flexibly adapt, tightly wrap and pull the infusion tube, ensuring that the interception operation is carried out smoothly.

[0048] The clip body 1 has textured structures on both sides along its thickness direction to increase friction. These textured structures effectively increase the friction between the finger and the clip body 1. When a medical professional holds the clip body 1, the textured surfaces engage tightly with the skin of the finger, preventing the clip body 1 from slipping out of the hand. This is especially crucial in a busy medical environment, preventing problems such as tubing displacement and interruption of the infusion procedure due to accidental drop of the clip body 1, thus ensuring a smooth infusion process.

[0049] The two side walls of the intercepting trough 3 are respectively provided with protruding limiting protrusions 7, which are correspondingly arranged on the two side walls of the intercepting trough 3. Multiple limiting protrusions 7 are provided on the two side walls of the intercepting trough 3, and the limiting protrusions 7 on the same side are spaced apart along the length of the intercepting trough 3. These limiting protrusions 7 play a crucial role in restricting the infusion tube entering the intercepting trough 3, and can effectively prevent the infusion tube from accidentally moving back into the receiving tank 2.

[0050] After the flow closure operation is completed, the infusion tube is compressed and closed within the flow closure groove 3, at which point the fluid stops flowing. However, in a real medical environment, there may be many interfering factors, such as medical staff accidentally touching the infusion tube while operating other medical devices, or the patient's unintentional limb movements pulling on the infusion tube. Without the restraining protrusion 7, the infusion tube can easily slide back from the flow closure groove 3 to the receiving groove 2 under these external forces, causing the flow closure to fail and the fluid to start flowing again, which undoubtedly poses a great risk to the medical process.

[0051] The multiple, spaced-apart restrictive protrusions 7 act like sturdy "barriers." After the infusion tube enters the intercepting groove 3, these protrusions make close contact with the outer wall of the infusion tube, clamping it from both sides. On the one hand, they increase the resistance to the return movement of the infusion tube, making it difficult for it to move easily under slight external force. On the other hand, the corresponding protrusions ensure that the clamping of the infusion tube is uniform and stable, preventing the infusion tube from shifting or breaking free due to uneven force on one side.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
