Description

Technical Field

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

[0002] The extracorporeal blood circuit is an important part of the hemodialysis system. The extracorporeal blood circuit, dialyzer and dialysis device together form the extracorporeal circulation support system. The extracorporeal blood circuit is assembled from pipelines, arteriovenous pots and various accessories. The clamp is an important part of the blood circuit. At present, the clamp is used as a clamping tool for clamping the extracorporeal blood circuit. The clamp can block the flow of liquid in the pipeline or the contact between the blood in the pipeline and the outside air. During dialysis treatment, the clamp will clamp the unused side branch tube. At the end of dialysis, the main line needs to be clamped with a clamp to stop the flow of blood to avoid blood loss and contamination.

[0003] The front and rear ends of the clamp are provided with an inlet and an outlet to facilitate the insertion of the pipeline. The upper end of the clamp is a pressing part, which moves downward when the pressing part is subjected to force. When the pressing part moves to the lower end of the blocking part, the clamping operation of the clamp is completed. A clamp on the market has a pipeline passing through the clamp. Since the inner circumference of the clamp is a plane, the pipeline can move at will. When clamping, the pipeline may slide and deviate, resulting in poor clamping of the pipeline, thereby causing clinical accidents such as blood loss, leakage or contamination.

[0004] Therefore, how to avoid slippage during the pipe clamping process is a technical problem that technicians in this field currently need to solve. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The core of the utility model is to provide a clamp which can prevent the pipeline from slipping during clamping.

[0033] The clamp provided in the utility model is used for clamping pipelines, specifically for clamping pipelines in the medical field, specifically for clamping pipelines in extracorporeal blood circulation circuits (including main pipelines or various side branch tubes), playing a role in preventing the flow of liquid in the pipeline or preventing the blood in the pipeline from contacting with the outside air.

[0034] The specific embodiment 1 of the clip provided in the utility model is as follows: Figures 1 to 3 As shown, the clamp comprises a pressing portion 2, a first connecting portion 1, a supporting portion 3, a second connecting portion 4 and a blocking portion 5 which are connected in sequence. The pressing portion 2 can be engaged with the blocking portion 5. At this time, the pressing portion 2, the first connecting portion 1, the supporting portion 3, the second connecting portion 4 and the blocking portion 5 form a closed loop structure, and the pressing portion 2 can also be separated from the blocking portion 5. Optionally, the entire clamp can be an integrally formed structure or a spliced ​​structure. The clamp can specifically be an elastic member.

[0035] The first connection part 1 can be used as a force-bearing part during a pressing operation, and is used for connection and force buffering between the support part 3 and the pressing part 2. The second connection part 4 is used to connect the blocking part 5 and the support part 3. A first through hole 11 is provided on the first connection part 1 and a second through hole 41 is provided on the second connection part 4, so that the pipeline can pass through the clamp along the first direction X. Specifically, the first through hole 11 and the second through hole 41 are sequentially provided along the first direction X, and usually enter from the first through hole 11 and exit from the second through hole 41. Optionally, the size of the second through hole 41 is equal to that of the first through hole 11. Preferably, the central axes of the two can overlap, so that the first through hole 11 and the second through hole 41 have a better positioning effect on the pipeline, and the adaptability to the pipeline is better. The pipeline can fit with the first through hole 11 and the second through hole 41 and be positioned by the first through hole 11 and the second through hole 41, or can move in the first through hole 11 or the second through hole 41, but remain in a centered state, which can avoid the hole wall from seriously hitting the pipeline and affecting the normal passage of the pipeline. Of course, in other embodiments, the central axes of the first through hole 11 and the second through hole 41 may not be colinear, as long as the two have a sufficiently large overlapping area in the first direction X for the pipeline to pass through.

[0036] The blocking portion 5 can cooperate with the pressing portion 2 to block the pressing portion 2 during the clamping operation to achieve a closing effect and prevent the clip from loosening. The side of the blocking portion 5 facing the pressing portion 2 is a sloped surface. The blocking portion 5 is connected to the second connecting portion 4 from the connecting area a (for details, please refer to Figure 2 The outer edge 52 is divided into the area corresponding to the dotted circle a), the side close to the support portion 3 is the inner edge 51, and the other side is the outer edge 52. The free end of the outer edge 52 is provided with a protruding structure b, which can be a protruding structure that protrudes 10 to 30 degrees relative to the surface of other structures on its edge. The protruding structure b is mainly or entirely located on the side of the outer edge 52 facing the pressing portion 2, wherein the free end of the outer edge 52 is the end structure away from the inner edge 51 and the connecting area a. Figure 1 In the shown orientation, the free end of the outer edge 52 is the upper end structure of the outer edge, which is usually also the top structure of the outer edge 52 when in use. Specifically, at 1 / 3 of the free end side of the outer edge 52, it is the position for force application when the clip is opened, thereby conveniently separating the pressing part 2 from the inner edge 51 of the blocking part 5.

[0037] In addition, the angle between at least part of the structure of the inner edge 51 of the blocking portion 5 and the second connecting portion 4 is between 20 degrees and 40 degrees. Specifically, the angle between the side of the inner edge 51 of the blocking portion 5 close to the second connecting portion 4 and the 1 / 3 portion from the free end point or edge position and the second connecting portion 4 is between 20 degrees and 40 degrees, so that the pressing portion 2 can extend into and engage with it, wherein the free end of the inner edge 51 is its end structure away from the outer edge 52 and the connecting area a. Figure 1 In the orientation shown, the free end of the inner edge 51 is the lower end structure of the inner edge 51, and is usually also the bottom end structure of the inner edge 51 when in use.

[0038] A positioning groove 33 for positioning the pipeline is provided on the side of the support portion 3 facing the pressing portion 2, and the positioning groove 33 extends along the first direction X. The second direction Y is the through direction of the closed-loop structure formed by the clip after the pressing portion 2 is engaged with the blocking portion 5. Preferably, the positioning groove 33 can be provided in the middle of the side of the support portion 3 facing the pressing portion 2 in the second direction Y, so as to position the pipeline in the middle of the corresponding side of the support portion 3 in the second direction Y. Of course, in other embodiments, the positioning groove 33 can be provided at the edge position of the side of the support portion 3 facing the pressing portion 2 in the second direction Y to meet the positioning requirements of pipelines of special shapes (such as curved pipes). Preferably, the central axes of the positioning groove 33, the first through hole 11, and the second through hole 41 can be arranged in a colinear manner, so as to achieve reliable positioning of the pipeline through the cooperation of the three.

[0039] When in use, the pipeline extends into the clamp from the first through hole 11 along the first direction X, and then extends out from the second through hole 41. During the process of the pipeline passing through, it can be positioned with the help of the positioning groove 33, and at least part of the structure of the pipeline enters the positioning groove 33, so that in the second direction Y, the pipeline can be clamped on the support part 3 to avoid slipping; then, the pressing part 2 is pressed toward the support part 3, so that the pressing part 2 continuously presses the pipeline on the support part 3 until the pressing part 2 and the blocking part 5 are engaged, at this time, the pressing part 2 and the support part 3 clamp the pipeline, because the pipeline will not slip on the support part 3, it can effectively prevent the pipeline from detaching from the support part 3, ensure the reliability of clamping, and improve the safety of dialysis. After clamping is no longer needed, the blocking part 5 is pressed to release the clamping of the pressing part 2, so that the pressing part 2 and the blocking part 5 are separated, and the pressing part 2 can be away from the support part 3, and the clamping of the pipeline by the pressing part 2 and the support part 3 is released.

[0040] like Figure 2 and Figure 3 As shown, the first protrusion 23 is protruded from the side of the pressing part 2 facing the supporting part 3. After the pressing part 2 is engaged with the blocking part 5, the first protrusion 23 can be pressed toward the supporting part 3 to clamp the pipeline. Among them, the first protrusion 23 is an arc-shaped protrusion protruding toward the supporting part 3, and the arc-shaped protrusion has the second direction Y as the axial direction. Since the first protrusion 23 is used to squeeze the pipeline to close the pipeline, based on its arc-shaped structural setting, it can prevent the first protrusion 23 from damaging blood cells in the blood while preventing the flow of liquid.

[0041] like Figure 2 and Figure 3As shown, in the first direction X, a plurality of support protrusions are sequentially arranged on the side of the support portion 3 facing the pressing portion 2, and a positioning groove 33 is respectively arranged on each support protrusion, so that the pipeline can be positioned at different positions to improve the reliability of positioning. Specifically, there are gaps between different support protrusions, and the side of the support portion 3 facing the pressing portion 2 is an uneven surface due to the presence of the support protrusions.

[0042] like Figure 2 and Figure 3 As shown, the supporting protrusion includes a second protrusion 31 and a third protrusion 34 which are sequentially arranged along the first direction X and away from the first through hole 11. Specifically, the second protrusion 31 and the third protrusion 34 are connected together by integrated injection molding. Among them, the positioning groove 33 on the second protrusion 31 is a first positioning groove 331, and the positioning groove 33 on the third protrusion 34 is a second positioning groove 332. The first positioning groove 331 and the second positioning groove 332 can be connected as a whole.

[0043] like Figure 2 As shown, the depth of the second positioning groove 332 is less than the depth of the first positioning groove 331. Optionally, the first positioning groove 331 is an arc-shaped groove, specifically, an arc-shaped channel with a depth of 1-3 mm and a width of 4-8 mm in the second direction Y, which can effectively fix a catheter with an outer diameter of 3-8 mm in the first positioning groove 331 for reliable positioning; the second positioning groove 332 is a guide groove with a depth of 0.5-2 mm, a length in the first direction X that is half of the third protrusion 34, and a width in the second direction Y of 2-4 mm. Specifically, in the first direction X, the second positioning groove 332 is arranged at one end close to the first positioning groove 331.

[0044] The deeper first positioning groove 331 plays a major positioning role, while the second positioning groove 332 is shallower, specifically, it can be less than the wall thickness of the pipe such as the catheter. After the pressing part 2 is engaged with the blocking part 5, the first protrusion 23 can be pressed against the docking area between the second protrusion 31 and the third protrusion 34, specifically, against the clamping end 341 of the third protrusion 34 close to the second protrusion 31, so as to clamp the pipe. When clamping, the second protrusion 31 is used in conjunction with the first protrusion 23. The second protrusion 31 can provide support force when clamping the pipe, and the third protrusion 34 is used to cooperate with the pressing part 2 during the clamping process to completely clamp the pipe. At this time, the second positioning groove 332 can ensure that the pipe at the clamping position does not slip without affecting the clamping effect. In addition, in addition to the part of the pipe that enters the second positioning groove 332, another part can be lifted a little by the clamping end 341 to facilitate the application of pressure.

[0045] Furthermore, if Figure 3As shown, the positioning groove 33 on the third protrusion 34 is arranged on a side close to the second protrusion 31. In the first direction X and in the direction away from the first through hole 11: the second protrusion 31 and the third protrusion 34 are arranged in sequence, and the depth of the positioning groove 33 on the third protrusion 34 gradually decreases, and the pipeline can pass through along the second positioning groove 332, and at the position where clamping is not required, the constraint of the support part 3 on the pipeline can be reduced.

[0046] Among them, the second protrusion 31 is arranged at the position on the support part 3 that is docked with the first connecting part 1 to increase the docking area between the first connecting part 1 and the support part 3. The second protrusion 31 can realize a stable connection between the first connecting part 1 and the support part 3, and the pipeline can be well stuck in the first positioning groove 331 to prevent the pipeline from being offset inside the clamp.

[0047] Among them, in the first direction X and in the direction away from the first through hole 11, starting from the clamping end 341, the side of the third protrusion 34 facing the pressing portion 2 gradually deviates from the pressing portion 2, and the third protrusion 34 is an inclined support body, so that the pipeline can smoothly escape from the limitation of the positioning groove 33, reduce the setting of the sharp-angle structure, and avoid damaging the pipeline.

[0048] Of course, in other embodiments, the first protrusion 23 may not need to extend into the positioning groove 33 to clamp this part of the pipeline, but instead presses a position on the side of the support portion 3 facing the pressing portion 2 in the first direction X that is offset from the positioning groove 33.

[0049] like Figure 1 and Figure 2 As shown, the side of the pressing portion 2 away from the supporting portion 3 (i.e., the side of the pressing portion 2 opposite to the side facing the supporting portion 3) includes a first pressing platform 21 and a second pressing platform 22. The first pressing platform 21 is arranged between the second pressing platform 22 and the first connecting portion 1. The first pressing platform 21 and the second pressing platform 22 are butted together to form a bending surface 26, and the angle of the bending surface 26 is opened toward the supporting portion 3, and the angle is specifically an obtuse angle. Optionally, the first pressing platform 21 and the second pressing platform 22 are planes.

[0050] Since the first pressing platform 21 and the second pressing platform 22 are connected to form a bending surface 26, which is adapted to the shape of the two knuckles of the thumb when bent toward the palm side, there can be at least part of the time during the thumb pressing process when the two knuckles of the thumb can be placed on the first pressing platform 21 and the second pressing platform 22 respectively. The thumb as a whole applies pressure to the pressing part 2, which reduces the stress concentration on the thumb, can better fit the thumb joint, conforms to ergonomics, improves the comfort of the pressing operation, and promotes better downward transmission of the pressing force, thereby saving the force during pressing, reducing labor intensity, and reducing symptoms such as hand soreness caused by a large amount of force clamping operations by medical staff. In addition, due to the positioning of the thumb by the pressing part 2, the possibility of the thumb slipping off the pressing part 2 is reduced, thereby improving the reliability of use.

[0051] like Figure 1 and Figure 2 As shown, on the pressing portion 2, in order to further prevent the thumb from slipping off the pressing portion 2, an anti-slip tooth surface 221 can be provided on the second pressing platform 22 to increase the friction force when pressing and ensure the anti-slip effect.

[0052] like Figure 1 and Figure 2 As shown, the first connection part 1 is an arc-shaped structure, constituting an arc-shaped curved support body. The first connection part 1 protrudes in a direction away from the second connection part 4. When in use, the first connection part 1 is close to the base of the hand and protrudes in the direction of the base of the hand, which can further improve the comfort of use. Optionally, the central angle of the first connection part 1 ranges from 120 degrees to 160 degrees. Optionally, on the first connection part 1, the central angles of the arc-shaped parts on both sides of the first through hole 11 are both between 60 degrees and 80 degrees.

[0053] like Figure 1 and Figure 2 As shown, the first pressing platform 21 is connected to the first connecting portion 1 to form an angle structure 25, and the top of the angle structure 25 protrudes toward the supporting portion 3, which can prevent the first connecting portion 1 from affecting the angle setting of the bending surface 26 of the pressing portion 2, thereby achieving smooth connection between the pressing portion 2 and the first connecting portion 1. Optionally, the angle of the angle structure 25 formed by the first pressing platform 21 and the first connecting portion 1 is between 100 degrees and 150 degrees.

[0054] Furthermore, if Figure 2 As shown, the pressing part 2 is provided with a first hollow hole 24 along the second direction Y, and the supporting part 3 is provided with a second hollow hole 32 along the second direction Y, which can be provided at the third protrusion 34. Through the hollow design, the overall weight of the clip can be effectively reduced, the cost can be saved, and the force during pressing can be saved, which further reduces the labor intensity and achieves the purpose of reducing the processing cost.

[0055] The clamp of the utility model comprises the following operating steps:

[0056] In the first step, the pipeline is passed through the first through hole 11 on the first connecting part 1, and the pipeline is inserted into the first positioning groove 331 on the second protrusion 31 and the second positioning groove 332 on the third protrusion 34;

[0057] Step 2: The pipeline passes through the second through hole 41 on the second connecting part 4;

[0058] Step 3: When it is necessary to stop the flow of blood or other liquids, place the index finger on the lower end of the third protrusion 34, place the thumb on the first pressing platform 21 and the anti-slip tooth surface 221 of the pressing part 2, and press the pressing part 2 downward with the thumb to make the pressing part 2 clamped at the lower end of the blocking part 5. At the same time, the arc-shaped convexity of the first protrusion 23 increases the contact area with the clamping end 341 on the third protrusion 34. The closure of the first protrusion 23 and the third protrusion 34 effectively clamps the catheter and stops the flow of liquid in the catheter, thereby completing the clamping operation.

[0059] The fourth step is, when it is necessary to release the blockage of the flow of blood or other liquids, the thumb of one hand is placed on the pressing part 2, the index finger is placed on the lower end of the third protrusion 34, and the thumb of the other hand is placed on the protruding structure b of the outer edge 52 of the blocking part 5, and the thumb is bent outward to separate the pressing part 2 from the blocking part 5, thereby completing the operation of releasing the blockage of the liquid flow.

[0060] The clamp provided by the utility model has a pressing portion 2 with a curved design, so that the pressing portion 2 can be better stressed, and the pipeline can be clamped with less force, reducing the labor intensity of medical staff and the unpleasant experience of hand soreness; the supporting portion 3 of the clamp is provided with a second protrusion 31 and a third protrusion 34, and a positioning groove 33 is provided on the second protrusion 31 and the third protrusion 34. The pipeline inside the clamp can be well stuck in the positioning groove 33, avoiding the loose clamping caused by sliding deviation when the pipeline passes through the clamp. At the same time, the clamping end 341 on the third protrusion 34 is used together with the pressing portion 2 to achieve reliable clamping, which can effectively prevent the occurrence of clinical accidents such as blood loss, leakage or pollution.
