[0041] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating relative importance or indicating the quantity of technical features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined. The following describes the specific implementation of the present utility model in more detail with reference to specific embodiments:

[0042] Such as Figure 1 and Figure 2As shown in the figure, a catheter stop-flow and breakage device provided by an embodiment of the present utility model can be applied to a blood collection system; specifically, the catheter stop-flow and breakage device integrates the functions of stopping the flow, conducting, and breaking the catheter, reducing the operation part of the blood collection staff, reducing the workload, and improving the work efficiency; the following will be described through specific embodiments:

[0043] The catheter stop-flow and breakage device of this embodiment includes:

[0044] A rotary fixing member 1, a rotary moving member 2 provided on the rotary fixing member 1, and a driving member 3 connected to the rotary moving member 2; wherein, the driving member 3 is provided on the rotary fixing member 1, the driving member 3 is provided with a power output shaft 31 penetrating the rotary fixing member 1, the rotary moving member 2 is connected to the power output shaft 31, the rotary moving member 2 can rotate relative to the rotary fixing member 1 around the power output shaft 31 under the drive of the driving member 3, a clamping groove 21 is provided on the rotary moving member 2, the clamping groove 21 is provided with a clamping groove 22 for accommodating the catheter 4, and the clamping groove 21 can rotate around the power output shaft 31 by a preset angle to break the heat-sealed catheter 4; a stop-flow member 11 is provided on the rotary fixing member 1, the stop-flow member 11 is located outside the clamping groove 21, the stop-flow member 11 stops the flow of the catheter 4 when it is opposite to the clamping groove 22, and the stop-flow member 11 conducts the catheter 4 when it is misaligned with the clamping groove 22.

[0045] Here, it can be understood that the rotary fixing member 1 refers to a component for relatively fixing the catheter stop-flow and breakage device. At the same time, the rotary fixing member 1 is used to support the rotary moving member 2 so that the rotary moving member 2 can rotate relative to the rotary fixing member 1; a stop-flow member 11 is provided on the rotary fixing member 1, and the stop-flow member 11 refers to a component for stopping the flow of the catheter 4. The stop-flow member 11 is used to abut against a part of the catheter 4 so that the catheter 4 parts on both sides of this part are not connected to each other;

[0046] The rotary moving member 2 refers to a component that can rotate relative to the rotary fixing member 1; a clamping groove 21 is provided on the rotary moving member 2, and the clamping groove 21 is provided with a clamping groove 22, and the catheter 4 can be accommodated in the clamping groove 22;

[0047] The driving member 3 refers to a component for driving the rotary moving member 2 to rotate; the driving member 3 generally refers to a motor or a cylinder. The driving member 3 has a power output shaft 31, and the power output shaft 31 penetrates the rotary fixing member 1 and is connected to the rotary moving member 2;

[0048] Such as Figures 3 to 5As shown in the figure, the driving member 3 drives the rotating movable member 2 to rotate around the power output shaft 31 through the power output shaft 31. In this way, the rotating movable member 2 rotates relative to the rotating fixed member 1, and the rotating movable member 2 drives the clamping groove clip 21 to rotate around the power output shaft 31. Since the flow stop member 11 is located outside the clamping groove clip 21, the flow stop member 11 is located on the rotation track of the clamping groove clip 21. Therefore, the flow stop member 11 will meet or separate from the clamping groove clip 21, that is, the clamping groove clip 21 will approach or depart from the flow stop member 11 when rotating; as Figure 3 shown, when the clamping groove clip 21 drives the catheter 4 away from the flow stop member 11, the clamping groove clip 21 separates from the flow stop member 11, making the catheter 4 conductive. At this time, the blood collection staff can perform blood collection operations, allowing blood to pass through the catheter 4; as Figure 4 shown, when the clamping groove clip 21 drives the catheter 4 close to the flow stop member 11, the clamping groove clip 21 and the flow stop member 11 jointly clamp the catheter 4 and squeeze the part of the catheter 4 located between the clamping groove clip 21 and the flow stop member 11, thereby realizing the flow stop of the catheter 4, that is, the two sides of the catheter 4 in this part are not connected to each other. At this time, the blood collection staff stops the blood collection operation and prepares to heat-seal the catheter 4; as Figure 5 shown, when the catheter 4 is heat-sealed, that is, the part of the catheter 4 located outside the catheter flow stop and break device is heat-sealed, the driving member 3 drives the rotating movable member 2 to rotate around the power output shaft 31 through the power output shaft 31, so that the catheter 4 is wound around the clamping groove clip 21 to tighten the catheter 4, and finally the catheter 4 is torn off from the heat-sealed part.

[0049] By adopting the above technical solution, the catheter flow stop and break device integrates the functions of conducting, stopping the flow, and tearing off the catheter 4, reduces the complexity of the operation during blood collection, reduces the workload of the blood collection staff, and improves the blood collection work efficiency.

[0050] In one embodiment, the rotating movable member 2 is defined with a first rotation direction X and a second rotation direction Y opposite to the first rotation direction X. When the rotating movable member 2 rotates around the power output shaft 31 along the first rotation direction X until the clamping groove 22 is opposite to the flow stop member 11, the clamping groove clip 21 and the flow stop member 11 jointly clamp the catheter 4 to stop the flow of the catheter 4; when the rotating movable member 2 rotates around the power output shaft 31 along the second rotation direction Y to displace the clamping groove 22 from the flow stop member 11, the clamping groove clip 21 and the flow stop member 11 are displaced to conduct the catheter 4.

[0051] Here, it can be understood that the rotating movable member 2 is defined with a first rotation direction X and a second rotation direction Y, and the first rotation direction X is opposite to the second rotation direction Y. In this embodiment, for example, the first rotation direction X is the counterclockwise direction, and the second rotation direction Y is the clockwise direction; as Figure 4 and Figure 5As shown, in the initial state, the card slot clip 21 is located below the flow stop member 11 in the first rotation direction X. The rotating movable member 2 drives the card slot clip 21 to rotate along the first rotation direction X. When the card slot clip 21 faces the flow stop member 11, the card slot clip 21 and the flow stop member 11 jointly clamp the catheter 4, and the clamped part of the catheter 4 is squeezed to achieve flow stoppage. When the rotating movable member 2 drives the card slot clip 21 to rotate along the second rotation direction Y, the card slot clip 21 and the flow stop member 11 are misaligned. At this time, the catheter 4 is not clamped to achieve conduction.

[0052] By adopting the above technical solution, rotating the movable member to switch different rotation directions can achieve the conduction and flow stoppage of the catheter 4. Its operation steps are simple, which is beneficial to improving the switching efficiency of the conduction and flow stoppage of the catheter 4.

[0053] As Figure 5 shown, in one embodiment, when the card slot clip 21 rotates around the power output shaft 31 along the second rotation direction Y by a preset angle, it can break the heat-sealed catheter 4.

[0054] Here, it can be understood that the rotating movable member 2 can drive the card slot clip 21 to rotate around the power output shaft 31. When the card slot clip 21 rotates around the power output shaft 31 along the second rotation direction Y, the card slot clip 21 drives the catheter 4 to rotate. At the same time, the catheter 4 is wound around the card slot clip 21, making the whole catheter 4 taut. Since the other end of the catheter 4 is connected to the heat-sealing device, in this way, the card slot clip 21 pulls the catheter 4, causing the catheter 4 to separate from the heat-sealed part.

[0055] By adopting the above technical solution, the function of the card slot clip 21 to break the catheter 4 is realized.

[0056] As Figure 6 shown, in one embodiment, the card slot clip 21 includes a first card slot portion 211 and a second card slot portion 212 provided on the rotating movable member 2. A card slot 22 is formed between the first card slot portion 211 and the second card slot portion 212. The first card slot portion 211 and the second card slot portion 212 are spaced apart by a preset distance, and the preset distance is slightly smaller than the outer diameter of the catheter 4, so that the catheter 4 is tightly fitted in the card slot 22.

[0057] Here, it can be understood that the card slot clip 21 is used to accommodate the catheter 4. The card slot clip 21 includes a first card slot portion 211 and a second card slot portion 212. The two are spaced apart by a preset distance to form the card slot 22. The preset distance is slightly smaller than the outer diameter of the catheter 4, so that when the catheter 4 is placed in the card slot 22, it can be tightly fitted with the card slot 22, that is, the catheter 4 is stuck in the card slot 22.

[0058] By adopting the above technical solution, the catheter 4 is not easily detached from the card slot 22, improving the stability of the catheter 4 during conduction, flow stoppage, and breaking.

[0059] In one embodiment, the slot 22 is an “S” shaped slot 22 .

[0060] Here, it can be understood that the shape of the slot 22 is “S”-shaped, so that the catheter 4 extends along the “S”-shaped bend when placed in the slot 22 , further improving the stability of the catheter 4 in the slot 22 .

[0061] By adopting the above technical solution, the stability of the catheter 4 in the slot 22 is further improved.

[0062] In one embodiment, the first slot portion 211 is located at the rear side of the second slot portion 212 in the second rotation direction Y, and the first slot portion 211 is formed with a sharp corner portion 2111 that cooperates with the flow stopper 11 .

[0063] Here, it can be understood that the rotating movable part 2 drives the first slot portion 211 to rotate along the second rotation direction Y, so that the catheter 4 is wrapped around the second slot portion 212, and then the catheter 4 is torn off from the heat-sealed part. During this process, the catheter 4 abuts against the sharp-angled part 2111 of the first slot portion 211, and the parts of the catheter 4 on both sides of the sharp-angled part 2111 form an acute angle, which increases the friction between the catheter 4 and the sharp-angled part 2111, and increases the force of the first slot portion 2111 to pull the catheter 4, which is conducive to tearing off the catheter 4.

[0064] By adopting the above technical solution, the catheter 4 can be easily torn off.

[0065] In one embodiment, the slot clamp 21 further includes a third slot portion 213 connected to the first slot portion 211 . The third slot portion 213 is located on a side of the first slot portion 211 away from the second slot portion 212 . The third slot portion 213 extends along the second rotation direction Y.

[0066] Here, it can be understood that the third slot portion 213 is used to expand the range of the catheter 4 and increase the pulling force applied to the catheter 4 when it is pulled; specifically, when the rotating movable part 2 drives the first slot portion 211 and the third slot portion 213 to rotate along the second rotation direction Y, the portion of the catheter 4 located outside the catheter flow stop and tearing device is wrapped around the first slot portion 211 and the third slot portion 213. The larger the range of the catheter 4, the greater the pulling force applied to it. This is more conducive to the catheter 4 being torn apart at the heat-sealed part.

[0067] The adoption of the above technical solution is conducive to the card slot clamp 21 tearing off the catheter 4, thereby improving the reliability of the tearing-off function.

[0068] In one embodiment, a placement slot 214 communicating with the slot 22 is formed between the third slot portion 213 and the rotating movable member 2 .

[0069] Here, it can be understood that the placement groove 214 is used to facilitate the blood collection staff to place the catheter 4; specifically, after the blood collection staff places the catheter 4 into the card slot 22, the catheter 4 can be pressed into the placement groove 214 by the thumb, so that the catheter 4 is synchronously locked into the card slot 22.

[0070] It needs to be further explained that the shape and size of the placement groove 214 match the fingers of the blood collection staff, so that the fingers of the blood collection staff can be pressed into the placement groove 214.

[0071] By adopting the above technical solution, it is beneficial for the catheter 4 to be locked into the card slot 22.

[0072] Please refer to again Figure 2 , in one embodiment, the rotating movable member 2 is provided with a trigger member 23, and the rotating fixed member 1 is provided with an induction member 12 for detecting the trigger member 23, and the induction member 12 is electrically connected to the driving member 3.

[0073] Here, it can be understood that the trigger member 23 is used to be detected by the induction member 12, and the trigger member 23 can be a trigger block; the induction member 12 is used to detect the position of the trigger member 23, and the induction member 12 can be an inductor; the trigger member 23 rotates with the rotating movable member 2, and the trigger member 23 is set to be detectable by the inductor when it rotates to a certain position; for example, when the rotating movable member 2 drives the card slot clip 21 to rotate to face the flow stop member 11, the trigger member 23 rotates to the corresponding position and is detected by the induction member 12, and the induction member 12 sends a control signal to the driving member 3, so that the driving member 3 stops the movement of the rotating movable member 2, and the card slot clip 21 is kept at the position of clamping the catheter 4.

[0074] By adopting the above technical solution, the automation degree of the catheter flow stop and break device is improved.

[0075] In a second aspect, a blood collection system is provided, including a blood collection system host and the above-mentioned catheter flow stop and break device, and the catheter flow stop and break device is connected to the blood collection system host.

[0076] By adopting the above technical solution, on the basis of having the advantages of the catheter flow stop and break device in the above embodiment, the blood collection system in this embodiment also has the advantage of high blood collection efficiency.

[0077] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
