Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a flushing line and a flushing line assembly. Background Technology

[0002] Flushing tubing is an indispensable part of medical devices, playing a vital role in surgery and treatment. However, during use, foreign objects such as air bubbles and particles can enter the interventional pump and the human body, resulting in lower safety and reliability of the flushing tubing.

[0003] In summary, how to reduce the probability of foreign objects such as air bubbles and particles entering the interventional pump and the human body, so as to improve the safety and reliability of the flushing pipeline, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a flushing pipeline and a flushing pipeline assembly to reduce the probability of foreign objects such as air bubbles and particles entering the interventional pump and the human body, so as to improve the safety and reliability of the flushing pipeline.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A flushing pipeline, characterized in that it comprises: an inlet pipe, a outlet pipe, and a circulation pipe, wherein the inlet of the inlet pipe is connected to a first reservoir, the outlet of the outlet pipe is connected to the flushing fluid inlet of an interventional pump, the inlet of the circulation pipe is connected to the flushing fluid outlet of the interventional pump, and the outlets of the inlet pipe and the circulation pipe are both connected to the inlet of the outlet pipe.

[0007] The inlet pipe has a first position for connecting to the flushing pump, and the outlet pipe has a second position for connecting to the circulation pump.

[0008] The liquid outlet pipe is equipped with a bubble filter, which is used to be installed on the outlet side of the circulating pump;

[0009] The circulation pipe is equipped with a particulate filter, which is distributed on the inlet side of the circulation pump; and / or, the liquid outlet pipe is equipped with a particulate filter, which is distributed on the outlet side of the circulation pump.

[0010] In the flushing pipeline provided in this application, an air bubble filter is installed in the fluid outlet pipe, and the air bubble filter is installed on the outlet side of the circulating pump. This filters out air bubbles in the flushing fluid before it enters the interventional pump, reducing the probability of air bubbles entering the interventional pump and thus the human body. For example, it can prevent air bubbles from entering the interventional pump and thus the human body, thereby reducing the probability of air embolism and improving the safety and reliability of the flushing pipeline. A particulate filter is used to filter out particulate matter and other foreign objects in the flushing fluid, thus reducing the probability of particulate matter and other foreign objects entering the interventional pump and thus the human body. For example, it can prevent particulate matter and other foreign objects from entering the interventional pump and thus the human body, thereby improving the safety and reliability of the flushing pipeline.

[0011] Meanwhile, in the flushing pipeline provided in this application, when the particulate filter is installed in the circulation pipe, it is distributed on the inlet side of the circulation pump. The particulate filter can withstand normal flow rates, meaning it can withstand normal speed differences, which is beneficial for monitoring the pressure in the flushing pipeline and the intervention pump, thus facilitating alarms in case of excessive pressure. When the particulate filter is installed in the infusion outlet pipe, it is distributed on the outlet side of the circulation pump. The particulate filter can withstand higher flow rates, meaning it can withstand higher speed differences, and correspondingly, can withstand a larger circulation flow rate under normal infusion flow conditions. Therefore, the different placement designs of the particulate filter can be applied to different scenarios, balancing particulate filtration effectiveness and overpressure risk management.

[0012] In some possible embodiments of this application, when the particulate filter is disposed in the circulation pipe and the particulate filter is distributed on the inlet side of the circulation pump, the speed difference between the circulation pump and the flushing pump is within a first range;

[0013] When the particulate filter is installed in the liquid outlet pipe and the particulate filter is distributed on the outlet side of the circulation pump, the speed difference between the circulation pump and the flushing pump is within a second range;

[0014] The upper limit of the first range is less than the upper limit of the second range.

[0015] In some possible embodiments of this application, where a particulate filter is provided in the liquid supply outlet pipe and the particulate filter is distributed on the outlet side of the circulating pump, the liquid supply outlet pipe is also provided with a pressure relief valve.

[0016] In some possible embodiments of this application, the pressure relief valve is used to be distributed on the outlet side of the circulating pump.

[0017] In some possible embodiments of this application, the circulating pump, the pressure relief valve, the particulate filter, and the bubble filter are distributed in sequence.

[0018] In some possible embodiments of this application, the outlet of the liquid inlet pipe, the outlet of the circulation pipe, and the inlet of the liquid supply pipe are connected by a connector. The housing of the connector is provided with a snap-fit ​​structure, which is used to snap-fit ​​with the housing of the flushing pump drive device.

[0019] In some possible embodiments of this application, the connector housing includes: a housing body and a cover plate that closes a first end of the housing body;

[0020] The snap-fit ​​structure is located at the second end of the housing body.

[0021] In some possible embodiments of this application, the snap-fit ​​structure includes a first snap-fit ​​plate located inside the housing body; and / or, the cover plate snaps into the housing body.

[0022] In some possible embodiments of this application, where the cover plate and the housing body are engaged:

[0023] The circumferential sidewall of the main body of the housing and the cover plate are provided with a third locking hole and a third locking buckle, respectively.

[0024] And / or, in the housing body and the cover plate, one is provided with a second retaining plate and the other is provided with a second retaining groove.

[0025] In some possible embodiments of this application, the cover plate is provided with a first connecting ring, the third buckle is provided on the circumferential outer wall of the first connecting ring, and the third buckle hole is provided on the circumferential inner wall of the housing body;

[0026] The cover plate is provided with a second connecting ring, and the second slot is provided in the second connecting ring;

[0027] The first connecting ring is located on the periphery of the second connecting ring.

[0028] Based on the flushing pipeline provided in this application, this application also provides a flushing pipeline assembly, which includes: a functional board, and the flushing pipeline described in any of the above embodiments;

[0029] The functional plate is used to support the fluid processing device of the flushing pipeline. The functional plate includes a first liner and a second liner. The first end of the second liner is connected to the first liner. The second liner is provided with a support structure and has a supported state and a non-supported state. In the non-supported state, the second end of the second liner can move to the first end of the second liner to the supported state. In the supported state, the first liner supports the second liner, and the support structure can support the fluid processing device.

[0030] In the flushing pipeline assembly provided in this application, the fluid processing device of the flushing pipeline is supported by the support structure of the functional plate, so that the fluid processing device can maintain its working posture, improving the fluid processing effect of the fluid processing device, thereby improving the working effect of the flushing pipeline; at the same time, the second liner has a supported state and a non-supported state, so that the functional plate has two forms (supported form and non-supported form), which can realize the functional plate in the non-supported form for packaging, transportation and storage, thereby reducing packaging cost, transportation cost and storage cost.

[0057] This application provides a functional board and a fluid pipeline assembly to improve the fluid processing effect of the fluid processing device and enhance the working effect of the fluid delivery pipeline.

[0058] The fluid delivery assembly provided in this application includes a fluid delivery line and a functional board. The fluid delivery line may include a flushing line and an arterial pressure measurement line. In this case, the fluid delivery line is suitable for a transcatheter ventricular assist device.

[0059] In practice, fluid delivery lines may also include flushing lines or arterial pressure measurement lines, and are not limited to the above embodiments.

[0060] To facilitate understanding of the flushing tubing and arterial pressure measurement tubing, we will first explain the transcatheter ventricular assist device.

[0061] A transcatheter ventricular assist device (VAVA) includes a VAVA control unit (hereinafter referred to as the control unit) and a VAVA interventional pump system (hereinafter referred to as the interventional pump system) used in conjunction with it. It is an interventional blood pump that provides mechanical circulatory support for patients with relevant indications. Users can monitor the system status and patient physiological parameters on the control unit interface and, according to the patient's needs, adjust the speed of the interventional pump to provide different levels of circulatory support, thereby temporarily maintaining blood circulation to the patient's vital organs and relieving the burden on the heart.

[0062] The interventional pump system mainly includes the interventional pump, delivery system, flushing tubing, and arterial pressure monitoring tubing. The flushing tubing can be understood as one type of fluid delivery tubing within the fluid tubing assembly, and the arterial pressure monitoring tubing can be understood as another type of fluid delivery tubing within the fluid tubing assembly.

[0063] like Figure 1 and Figure 2 As shown, the interventional pump 04 mainly includes: a protective tip 044, a pump head (containing an impeller, a support, and a diaphragm) 043, a repositioning sterile sleeve, a drive catheter 042, and a drive catheter handle 041. The drive catheter handle 041 includes: a drive catheter locking connector, a drive catheter handle housing, a seal, an arterial pressure sensor, a flushing pressure sensor, a flushing tubing inlet connector 0411, a flushing tubing outlet connector 0412, an arterial pressure monitoring tubing inlet connector 0413, and an arterial pressure monitoring tubing outlet connector 0414.

[0064] The interventional pump 04 can be percutaneously inserted into the heart through peripheral blood vessels. The pump head 043 is placed between the left ventricle and the aorta. The blood inlet of the pump head 043 is placed into the left ventricle, and the blood outlet of the pump head 043 is placed into the aorta, thereby pumping blood from the left ventricle into the aorta to achieve ventricular assist function.

[0065] The delivery system consists of a dilator, an interventional sheath 05, and an inserter. The system dilates blood vessels and provides access for the interventional pump 04 to be inserted into the heart. The inserter and interventional sheath 05 function to retract the pump head 043. The inserter and dilator are removed after the interventional pump 04 is in place. The interventional sheath 05 remains in the patient's blood vessel until the interventional pump 04 is removed; even after removal, the sheath 05 continues to retract the pump head 043.

[0066] The flushing pump drive device of the control host drives the flushing pump and the circulation pump, which can pump the flushing fluid in the flushing pipeline into the interventional pump 04 through the flushing pipeline, thereby preventing blood from entering the drive catheter 042; at the same time, there is a rotating part in the drive catheter handle 041, which rotates at high speed with a flexible shaft, reaching tens of thousands of revolutions per minute. The flushing fluid can pre-fill and flush the inner cavity where the rotating part is located to prevent air bubbles from entering the human body. The flushing fluid can also cool the inner cavity of the drive catheter handle 041.

[0067] The arterial pressure monitoring line can be connected to a pressure bag, which applies pressure to the arterial pressure monitoring line. By periodically opening the flushing valve, the arterial pressure monitoring pathway is flushed with saline to prevent thrombosis.

[0068] The main control unit includes: a control console, an intervention pump drive unit, and a flushing pump drive unit.

[0069] The flushing pump drive unit 01 is placed on the control panel 02, and the flushing tubing is installed on the flushing pump drive unit 01. The interventional pump drive unit 03 can be connected to the drive catheter handle 041 of the interventional pump 04. The interventional pump drive unit 03 drives the impeller of the interventional pump 04 to rotate, realizing the function of pumping blood from the left ventricle into the aorta. The motor speed of the interventional pump drive unit 03 can be set by rotating the knob on the control panel 02. During operation, if any high-risk situation occurs, the interventional pump drive unit 03 will send an alarm signal to the control panel 02.

[0070] In the aforementioned transcatheter ventricular assist device, after the drive catheter handle 041, the flushing tubing, and the flushing pump drive device 01 are connected, a flushing channel can be formed. Specifically, the flushing tubing inlet connector 0411 and the flushing tubing outlet connector 0412 of the drive catheter handle 041 are connected to the flushing tubing 100, the arterial pressure measurement tubing inlet connector 0413 of the drive catheter handle 041 is connected to the arterial pressure measurement tube 201 of the arterial pressure measurement tubing 200, and the arterial pressure measurement tubing outlet connector 0414 of the drive catheter handle 041 is connected to the pressure measurement interface 051 of the interventional sheath 05. The gap between the interventional sheath 05 and the drive catheter 042, and the connection between the drive catheter handle 041 and the arterial pressure measurement tube 201, form an arterial pressure measurement pathway.

[0071] The structure of the flushing line 100 and the arterial pressure measuring line 200 is described in detail below.

[0072] like Figures 2-5 As shown, the flushing pipeline 100 includes a flushing pipe 101 and a fluid device (not shown in the figure) disposed on the flushing pipe 101; wherein, the fluid device includes a fluid processing device.

[0073] The flushing pipe 101 includes: a liquid inlet pipe 1011, a liquid outlet pipe 1012, and a circulation pipe 1013. The inlet of the liquid inlet pipe 1011 is connected to the first liquid reservoir 300, the outlet of the liquid outlet pipe 1012 is connected to the flushing fluid inlet of the interventional pump 04, and the inlet of the circulation pipe 1013 is connected to the flushing fluid outlet of the interventional pump 04. The outlet of the liquid inlet pipe 1011, the outlet of the circulation pipe 1013, and the inlet of the liquid outlet pipe 1012 are connected by a connector 106.

[0074] It should be noted that connector 106 is a fluid device, and flushing pipe 101 is a fluid delivery pipe.

[0075] In practice, the outlet of the liquid inlet pipe 1011, the outlet of the circulation pipe 1013, and the inlet of the liquid supply pipe 1012 can also be connected through other components, and are not limited to connector 106.

[0076] It should be noted that the flushing fluid inlet of the interventional pump 04 can be understood as the flushing tubing inlet connector 0411 of the drive catheter handle 041; the flushing fluid outlet of the interventional pump 04 can be understood as the flushing tubing outlet connector 0412 of the drive catheter handle 041.

[0077] In the aforementioned flushing pipeline 100, the flushing fluid in the first reservoir 300 flows in through the inlet pipe 1011 and is pumped to the flushing fluid inlet of the interventional pump 04 through the outlet pipe 1012. After the flushing fluid enters the interventional pump 04, a portion of the flushing fluid enters the drive conduit 042 and is discharged through the drive conduit 042 to the pump head 043. The other portion of the flushing fluid flows into the circulation pipe 1013 through the flushing fluid outlet of the interventional pump 04, and then enters the outlet pipe 1012 through the connector 106 and is pumped to the flushing fluid inlet of the interventional pump 04. A high-speed flushing fluid circulation is formed between the outlet pipe 1012 and the circulation pipe 1013, thus realizing the circulation of the flushing fluid.

[0078] To ensure that the flushing fluid flows through the flushing pipeline 100, the aforementioned inlet pipe 1011 has a first position for connecting to the flushing pump 500, and the outlet pipe 1012 has a second position for connecting to the circulation pump 600.

[0079] The type of flushing pump 500 and circulation pump 600 should be selected based on the actual situation. To avoid contaminating the flushing fluid, both flushing pump 500 and circulation pump 600 can be peristaltic pumps. The peristaltic flushing pump 500 pumps fluid by alternately squeezing and releasing the inlet pipe 1011, while the peristaltic circulation pump 600 pumps fluid by alternately squeezing and releasing the outlet pipe 1012. In this way, the flushing fluid remains in the flushing pipeline 100 during the pumping process, effectively preventing contamination of the flushing fluid. In this case, the first position is used to install the flushing pump pipe 501 of the flushing pump 500, and the second position is used to install the circulation pump pipe 601 of the circulation pump 600.

[0080] In practice, the flushing pump 500 and the circulation pump 600 can also be other types, and this embodiment does not limit them.

[0081] In the aforementioned flushing pipeline 100, the supply outlet pipe 1012 and the circulation pipe 1013 are both located on the outlet side of the flushing pump 500, while the inlet pipe 1011 and the circulation pipe 1013 are both located on the inlet side of the circulation pump 600. Thus, the flow rate of the circulation pipe 1013 is generated by the speed difference between the flushing pump 500 and the circulation pump 600. Since the circulation pump 600 forces the flushing fluid into the drive guide handle 041, the outlet side of the circulation pump 600 (the side of the circulation pump 600 facing the flushing fluid inlet of the intervention pump 04) is the positive pressure zone corresponding to the circulation pump, and the inlet side of the circulation pump 600 (the side of the circulation pump 600 facing the circulation pipe 1013) is the negative pressure zone corresponding to the circulation pump. Based on this, the drive guide handle 041 is a positive pressure zone; since most of the flushing fluid in the circulation pipe 1013 is drawn to the supply outlet pipe 1012 by the circulation pump 600, the circulation pipe 1013 is a negative pressure zone. Among them, the flow rate of the flushing pump 500 is generally small to maintain the amount of flushing fluid entering the human body within a safe range, while the flow rate of the circulation pump 600 is generally large to perform high-speed circulation flushing of the inner cavity of the drive tube handle 041, so as to meet the cooling requirements of the high-speed rotation of the rotating parts in the drive tube handle 041.

[0082] During use, the flushing line 100 may contain foreign objects such as air bubbles and particles that could enter the intervention pump 04 and the human body, resulting in low safety and reliability of the flushing line 100. To address this technical problem, such as... Figures 3-5 As shown, to prevent air bubbles and particles from entering the intervention pump 04 and the human body, the flushing pipe 101 is equipped with an air bubble filter 107 and a particle filter 108. The air bubble filter 107 is a fluid handling device, and the particle filter 108 is another type of fluid handling device.

[0083] A bubble filter 107 is installed in the fluid outlet pipe 1012, and is positioned on the outlet side of the circulating pump. This filters out air bubbles in the flushing fluid before it enters the interventional pump 04, reducing the likelihood of bubbles entering the interventional pump 04 and thus the human body. For example, it can prevent air bubbles from entering the interventional pump 04 and thus the human body, thereby reducing the probability of air embolism and improving the safety and reliability of the flushing pipeline 100. The type of bubble filter 107 is selected according to the actual situation; this embodiment does not limit this selection.

[0084] The particulate filter 108 is used to filter out particulate matter and other foreign objects in the flushing fluid. This reduces the chance of particulate matter and other foreign objects entering the intervention pump 04 and thus entering the human body. For example, it can prevent particulate matter and other foreign objects from entering the intervention pump 04 and thus entering the human body, thereby improving the safety and reliability of the flushing pipeline 100.

[0085] The particulate filter 108 experiences a pressure drop, resulting in a pressure difference between its inlet and outlet. Typically, the inlet pressure of the particulate filter 108 is higher than its outlet pressure. As the particulate filter 108 begins collecting particles, its pressure drop gradually increases. Furthermore, the flow rate also affects the pressure drop; the faster the flow rate of the flushing fluid in the inlet pipe 1011, the greater the pressure drop at the particulate filter 108.

[0086] The location of the particulate filter 108 is selected based on the actual situation. In one possible implementation, such as... Figure 3 As shown, the particulate filter 108 can be installed in the circulation pipe 1013, and the particulate filter 108 is distributed on the inlet side of the circulation pump 600. In this way, when the inlet pressure of the particulate filter 108 increases or the internal pressure of the intervention pump 04 connected to it increases, the pressure sensor located inside the intervention pump 04 can promptly detect the increase in flushing pressure in the fluid channels, including the flushing pipe 100, and thus issue an alarm in a timely manner.

[0087] As mentioned earlier, the circulation pipe 1013 is a negative pressure zone, and the particulate filter 108 is also in a negative pressure zone. The flushing liquid passing through the particulate filter 108 is drawn out by the circulation pump 600. When the pressure drop of the particulate filter 108 is greater than a set value, air will be released from the liquid and can flow out through the filter screen in the particulate filter 108. The higher the pressure drop in the particulate filter 108, the easier it is for bubbles to be released. At the same time, due to the presence of the filter screen, gas passes through the filter screen more easily than liquid, so gas dissolved in the liquid is also more likely to be released, resulting in bubbles in the flushing pipe 100. When too much air is released, it is difficult for the released air to mix back into the liquid that already contains air (the liquid located on the outlet side of the particulate filter 108), and too many bubbles are also difficult to filter by the bubble filter 107.

[0088] Therefore, when the particulate filter 108 is installed in the circulation pipe 1013, the particulate filter 108 can withstand the normal flow rate, that is, the particulate filter 108 can withstand the normal speed difference (the speed difference between the flushing pump 500 and the circulation pump 600). For example, the speed difference between the circulation pump 600 and the flushing pump 500 is within a first range, which can be understood as the normal speed difference being within a first range. This is beneficial for monitoring the pressure in the flushing pipe 100 and the intervention pump 04, thereby facilitating alarms due to excessive pressure.

[0089] In another possible implementation, such as Figure 4 and Figure 5As shown, the particulate filter 108 can be installed in the infusion outlet pipe 1012, and the particulate filter 108 is distributed on the outlet side of the circulation pump 600. As mentioned above, the infusion outlet pipe 1012 is a positive pressure zone, so the particulate filter 108 is in a positive pressure zone. The flushing fluid is pumped into the particulate filter 108 by the circulation pump 600. Therefore, no matter how high the pressure drop value of the particulate filter 108 is, no air bubbles will overflow from the particulate filter 108. Based on this, the above structure can withstand higher flow rates, that is, it can withstand higher speed differences (speed differences between the flushing pump 500 and the circulation pump 600). For example, the speed difference between the circulation pump 600 and the flushing pump 500 is in the second range, which can be understood as a higher speed difference in the second range. Correspondingly, under normal infusion flow rates, it can withstand larger circulation flow rates (the speed difference will be larger). It is understood that in this structure, the pressure drop of the particulate filter 108 will still increase with the increase of particles in the flushing fluid.

[0090] It should be noted that the upper limit of the first range is smaller than the upper limit of the second range. The relative magnitudes of the lower limits of the first and second ranges are selected based on actual circumstances, and this application does not impose any limitations on this aspect.

[0091] When both the particulate filter 108 and the bubble filter 107 are located in the liquid outlet pipe 1012, the particulate filter 108 can be located between the connector 106 and the bubble filter 107 to facilitate the filtration of bubbles.

[0092] The different positions of the particulate filter 108 described above can be applied to different scenarios, balancing particulate filtration efficiency with overpressure risk management. Specifically, when the particulate filter 108 is in the negative pressure zone (located in the circulation pipe 1013), air will precipitate from the liquid to form bubbles when the pressure drop of the particulate filter 108 exceeds a set value. These bubbles will then flow out through the filter screen in the particulate filter 108. The higher the pressure drop within the particulate filter 108, the easier it is for bubbles to precipitate. When the particulate filter 108 is in the positive pressure zone (located in the liquid outlet pipe 1012), no bubbles will overflow from the particulate filter 108, regardless of the pressure drop value. Therefore, when the particulate filter 108 is in the negative pressure zone, the pressure drop within the particulate filter 108 needs to be controlled to avoid generating excessive bubbles. Since the pressure drop of the particulate filter 108 is affected by the flow rate of the flushing fluid through the particulate filter 108 (the faster the flow rate, the greater the pressure drop), and the flow rate of the flushing fluid through the particulate filter 108 is affected by the speed difference between the flushing pump 500 and the circulation pump 600 (the greater the speed difference, the faster the flow rate), in order to avoid excessive bubbles, it is necessary to control the speed difference between the flushing pump 500 and the circulation pump 600 to avoid generating too many bubbles. The pressure drop increase of particulate filter 108 is mainly reflected in the pressure increase at the inlet of particulate filter 108. When the inlet of particulate filter 108 is close to intervention pump 04 (particulate filter 108 is installed in circulation pipe 1013), the pressure sensor located inside intervention pump 04 can detect the pressure increase in flushing pipeline 100 in time, and thus issue an alarm in time. When the outlet of particulate filter 108 is close to intervention pump 04 (particulate filter 108 is installed in liquid outlet pipe 1012), since the pressure sensor inside intervention pump 04 is located at the handle end of intervention pump 04, the pressure increase in flushing pipeline 100 caused by blockage of particulate filter 108 may not be detected by the pressure sensor in time, which may result in excessive flushing pressure but no alarm in time.

[0093] The two possible implementation methods described above can be implemented individually or in combination. In the case of a combination of the two possible implementation methods, there are at least two particulate filters 108. At least one particulate filter 108 is provided in the circulation pipe 1013, and the particulate filter 108 on the circulation pipe 1013 is distributed on the inlet side of the circulation pump 600. At least one particulate filter 108 is provided in the liquid outlet pipe 1012, and the particulate filter 108 on the liquid outlet pipe 1012 is distributed on the outlet side of the circulation pump 600.

[0094] As mentioned earlier, when the outlet of the particulate filter 108 is close to the intervention pump 04 (when the particulate filter 108 is installed in the liquid outlet pipe 1012), there is a risk that the flushing pressure may be too high but an alarm may not be triggered in time. To reduce this risk, such as Figure 5As shown, the liquid outlet pipe 1012 is also equipped with a pressure relief valve 109. In this way, the pressure in the flushing pipe 100 is controlled by the pressure relief valve 109, so that the pressure in the flushing pipe 100 is less than the maximum pressure that the particulate filter 108 can withstand, thereby achieving the purpose of protecting the particulate filter 108.

[0095] It should be noted that the pressure relief valve 109 is a fluid device.

[0096] To improve the pressure relief effect of the pressure relief valve 109, the pressure relief valve 109 can be located on the outlet side of the circulating pump 600, such as between the particulate filter 108 and the circulating pump pipe 601. To improve the filtration effect of the particulate filter 108 and the bubble filter 107, the circulating pump 600, pressure relief valve 109, particulate filter 108 and bubble filter 107 can be arranged in sequence.

[0097] In practice, it is also possible to... Figure 3 A pressure relief valve 109 can be added to the flushing pipeline 100 shown, or... Figure 4 The flushing pipeline 100 shown is equipped with a pressure relief valve 109, which is not limited to... Figure 5 The structure shown.

[0098] like Figures 2-5 As shown, in the flushing pipeline 100, in order to facilitate the connection between the inlet of the liquid inlet pipe 1011 and the first liquid reservoir 300, the inlet of the liquid inlet pipe 1011 is provided with a first puncture device 103 and a first puncture device protective sleeve 102. The first puncture device protective sleeve 102 covers the first puncture device 103, and the first puncture device 103 is used to connect with the first liquid reservoir 300.

[0099] It should be noted that the first puncture device 103 is a fluid device, and the first puncture device protective sleeve 102 is another fluid device.

[0100] The type of the first puncture device 103 is selected according to the actual situation. For example, the first puncture device 103 is an integrated drip puncture device.

[0101] In the flushing pipeline 100, to facilitate the connection between the outlet of the fluid supply pipe 1012 and the interventional pump 04, an outlet connector 104 is provided at the outlet of the fluid supply pipe 1012. The outlet connector 104 is used to connect with the flushing fluid inlet of the interventional pump 04. Correspondingly, to facilitate the connection between the inlet of the circulation pipe 1013 and the interventional pump, a circulation pipe connector 105 is provided at the inlet of the circulation pipe 1013. The circulation pipe connector 105 is used to connect with the flushing fluid outlet of the interventional pump 04.

[0102] It should be noted that the outlet pipe connector 104 is a fluid device, while the circulation pipe connector 105 is another type of fluid device.

[0103] The type of outlet pipe connector 104 and circulation pipe connector 105 is selected according to the actual situation. For example, both outlet pipe connector 104 and circulation pipe connector 105 are Luer connectors.

[0104] In the flushing pipeline 100, the connector 106 can be a tee or other components, and this application embodiment does not limit this.

[0105] like Figure 6 As shown, in some embodiments, connector 106 includes: a housing (not labeled in the figure), a first connector 1062, a second connector 1063, and a third connector 1064. The first connector 1062, the second connector 1063, and the third connector 1064 are all disposed on the circumferential sidewall of the housing and are distributed sequentially along the circumference of the housing. The first connector 1062, the second connector 1063, and the third connector 1064 are all in communication with the inner cavity of the housing. The first connector 1062 can be connected to the outlet of the liquid inlet pipe 1011, the third connector 1064 can be connected to the outlet of the circulation pipe 1013, and the second connector 1063 can be connected to the inlet of the liquid outlet pipe 1012.

[0106] The housing of connector 106 can be cylindrical or other shapes, depending on the actual situation. This application embodiment does not limit this.

[0107] As mentioned above, the flushing line 100 is mounted on the flushing pump drive unit 01. To improve the stability of the flushing line 100 on the flushing pump drive unit 01, the housing of the connector 106 can be connected to the housing of the flushing pump drive unit 01. For the installation and removal of the connector 106, the housing of the connector 106 is provided with a snap-fit ​​structure for snapping into the housing of the flushing pump drive unit 01.

[0108] like Figures 6-9 As shown, in some embodiments, the housing of connector 106 includes a housing body 1061 and a cover plate 1065, wherein the cover plate 1065 closes a first end of the housing body 1061, and a snap-fit ​​structure is disposed at a second end of the housing body 1061. Thus, the structures at both ends of connector 106 are significantly different, facilitating the installation of connector 106 on the flushing pump drive device 01 and avoiding misinstallation; moreover, the snap-fit ​​structure is directly disposed on the housing body 1061, simplifying the overall structure of connector 106.

[0109] The specific structure of the snap-fit ​​structure is selected based on the actual situation. To simplify the structure, the snap-fit ​​structure may include a first snap-fit ​​plate 10613, which is located inside the housing body 1061. In this case, the housing of the flushing pump drive device 01 is provided with a first snap-fit ​​groove that mates with the first snap-fit ​​plate 10613. Of course, the positions of the first snap-fit ​​plate 10613 and the first snap-fit ​​groove can be interchanged; or, the snap-fit ​​structure may include a buckle, etc., which is not limited in this embodiment.

[0110] In the connector 106 described above, for ease of installation and disassembly, the cover plate 1065 and the housing body 1061 can be detachably connected. In some embodiments, the cover plate 1065 and the housing body 1061 are snap-fitted (detachably snap-fitted).

[0111] To facilitate the installation and removal of the cover plate 1065 and the housing body 1061, in one possible embodiment, the circumferential sidewall of the housing body 1061 and the cover plate 1605 are provided with a third latch 10611 and a third buckle 10652, respectively.

[0112] To facilitate the installation of the third latch 10652, the cover plate 1065 is provided with a first connecting ring 10651, and the third latch 10652 is disposed on the circumferential outer wall of the first connecting ring 10651. Of course, the third latch 10652 can be disposed at other positions on the cover plate 1065, and this embodiment of the application does not limit this.

[0113] To facilitate the installation of the third locking hole 10611, it can be located on the circumferential inner sidewall of the housing body 1061. Of course, the third locking hole 10611 can also be located in other positions, and this embodiment does not limit this.

[0114] The third locking hole 10611 and the third locking buckle 10652 are engaged and matched, and the third locking hole 10611 and the third locking buckle 10652 can correspond one-to-one.

[0115] The aforementioned third locking hole 10611 can be one or more, and correspondingly, the third latch 10652 can be one or more. When there are two or more third locking holes 10611, the third locking holes 10611 can be evenly distributed on the circumferential sidewalls of the housing body 1061 or the cover plate 1605.

[0116] To facilitate the installation and removal of the cover plate 1065 and the housing body 1061, in another possible embodiment, one of the housing body 1061 and the cover plate 1065 may be provided with a second retaining plate 10612 and the other with a second retaining groove 10654. The second retaining groove 10654 and the second retaining plate 10612 are engaged in a locking mechanism.

[0117] To facilitate the installation of the second slot 10654, the cover plate 1065 can be provided with a second connecting ring, and the second slot 10654 can be located on the second connecting ring 10653. Of course, the second slot 10654 can also be installed in other ways, and is not limited to the above structure.

[0118] The two possible implementation methods described above can be combined or implemented individually. In the case of a combination of the two possible implementation methods, the first connecting ring 10651 can be located outside the second connecting ring 10653. Of course, the second connecting ring 10653 can also be located outside the first connecting ring 10651; this application embodiment does not limit this.

[0119] The flushing line 100 was described above; the arterial pressure measurement line 200 will be described below.

[0120] like Figure 2 and Figure 10 As shown, the arterial pressure measuring line 200 includes an arterial pressure measuring tube 201 and a fluid device (not labeled in the figure) disposed on the arterial pressure measuring tube 201; wherein, the fluid device includes a fluid handling device. The arterial pressure measuring tube 201 is a fluid delivery tube.

[0121] The inlet of the arterial pressure measuring tube 201 is used to connect to the second reservoir 400, and the outlet of the arterial pressure measuring tube 200 is used to connect to the arterial pressure measuring interface of the interventional pump 04. The arterial pressure measuring interface of the interventional pump 04 can be understood as the arterial pressure measuring tube inlet connector 0413 that drives the catheter handle 041.

[0122] To facilitate the connection between the inlet of the arterial pressure measuring tube 201 and the second reservoir 400, the inlet of the arterial pressure measuring tube 201 is provided with a second puncture device 202 and a second puncture device protective sleeve 203. The second puncture device protective sleeve 203 covers the second puncture device 202, and the second puncture device 202 is used to connect with the second reservoir 400.

[0123] It should be noted that the second puncture device 202 is a fluid device, and the second puncture device protective sleeve 203 is another fluid device.

[0124] The type of the second puncture device 202 is selected according to the actual situation. For example, the second puncture device 202 is an integrated drip puncture device.

[0125] The arterial pressure measuring tube 201 is equipped with a flow regulator 204 to regulate the fluid flow rate within the arterial pressure measuring tube 201. The flow regulator 204 is a fluid control device.

[0126] The type of flow regulator 204 can be selected according to the actual situation, and this application embodiment does not limit it.

[0127] The arterial pressure measuring tube 201 can also be equipped with at least one of a bubble filter and a particulate filter. The bubble filter is a fluid handling device, and the particulate filter is another type of fluid handling device. For a description of the bubble filter and the particulate filter, please refer to the previous text, which will not be repeated here.

[0128] The arterial pressure measuring tube 201 is also equipped with a flushing valve 205 and a stop clamp 206. The flushing valve 205 can be used to control the flushing of the arterial pressure measuring tube 201, and the stop clamp 206 can be used to control the opening and closing of the arterial pressure measuring tube 201.

[0129] It should be noted that the flushing valve 205 is a fluid device, while the stop clamp 206 is another fluid device.

[0130] The type of flushing valve 205 and stop clamp 206 can be selected according to the actual situation, and this application embodiment does not limit this.

[0131] To facilitate the connection between the outlet of the arterial pressure measuring tube 201 and the interventional pump 04, the outlet of the arterial pressure measuring tube 201 is provided with an arterial pressure measuring tube connector 207, which is used to connect with the interventional pump 04.

[0132] It should be noted that the arterial pressure measuring tube connector 207 is a fluid device.

[0133] The type of arterial pressure measuring catheter connector 207 is selected based on the specific circumstances. For example, the arterial pressure measuring catheter connector 207 is a Luer connector.

[0134] When the arterial pressure measuring tube 201 is equipped with a second puncture device 202, a flow regulator 204, a flushing valve 205, a stop clamp 206, and an arterial pressure measuring tube connector 207, the second puncture device 202, the flow regulator 204, the flushing valve 205, the stop clamp 206, and the arterial pressure measuring tube connector 207 are distributed in sequence.

[0135] In some embodiments, the flushing line 100 and the arterial pressure measuring line 200 described above may also have other structures and are not limited to the above embodiments.

[0136] In practice, fluid delivery lines may also include other lines. For example, if the fluid delivery line is applicable to other interventional therapy devices, the design shall be based on the interventional therapy device to which the fluid delivery line is applicable; this embodiment does not limit this.

[0137] In the fluid pipeline assembly provided in this application embodiment, the functional board is used to support the fluid handling device of the fluid delivery pipeline. For example, the fluid handling device is a bubble filter 107 or a particulate filter 108, or at least one fluid handling device is a bubble filter 107 and at least one fluid handling device is a particulate filter 108.

[0138] The following describes a fluid delivery pipeline including a flushing pipeline 100 and an arterial pressure measurement pipeline 200, with a fluid handling device of a bubble filter 107. To improve the filtration efficiency of the bubble filter 107, it is necessary to ensure that the liquid flows through the bubble filter 107 from bottom to top as much as possible. Based on this, a function board can support the bubble filter 107. The following describes the function board in detail, using the example of the function board supporting the bubble filter 107.

[0139] like Figures 11-14 As shown, the functional board 1 includes: a first liner 11 and a second liner 12.

[0140] The first end of the second liner 12 is connected to the first liner 11; the second liner 12 is provided with a support structure 121, and the second liner 12 has a supported state and a non-supported state.

[0141] Figure 11 and Figure 12 The second liner 12 shown in the image is in an unsupported state; Figure 13 and Figure 14 The second liner 12 shown in the image is in a supported state.

[0142] In the unsupported state (when the second liner 12 is in the unsupported state), the second end of the second liner 12 can move to the first end of the second liner 12 to the supported state; in the supported state (when the second liner 12 is in the supported state), the first liner 11 supports the second liner 12, and the support structure 121 can support the fluid processing device (bubble filter 107).

[0143] It should be noted that, when the fluid delivery pipeline is in operation, the support structure 121 supports the fluid processing device (bubble filter 107). When the fluid delivery pipeline is in operation, it is mounted on the flushing pump drive device 01, which is a fluid-driven device.

[0144] The support structure 121 can be one or more, depending on the actual situation; this application embodiment does not limit this. Since the support structure 121 corresponds one-to-one with the fluid processing device, the fluid processing device can be one or more.

[0145] The second liner 12 can be one or more, and this application embodiment does not limit this.

[0146] In the functional board 1 provided in this application embodiment, the fluid processing device (bubble filter 107) is supported by the support structure 121, so that the fluid processing device can maintain its working posture, thereby improving the fluid processing effect of the fluid processing device and thus improving the working effect of the fluid conveying pipeline.

[0147] Meanwhile, in the functional board 1 provided in this application embodiment, the second liner 12 has a supported state and a non-supported state. In this way, the functional board 1 has two forms (supported form and non-supported form), which can realize the functional board 1 in the non-supported form for packaging, transportation and storage, thereby reducing packaging cost, transportation cost and storage cost.

[0148] In functional plate 1, the second liner 12 moves from a non-supported state to a supported state in various ways. To facilitate this movement, the second liner 12 can be rotated, such as by folding. Therefore, the first end of the second liner 12 and the first liner 11 can be connected by a crease 14, allowing the second end of the second liner 12 to move towards the first end to the supported state. This facilitates the movement of the second liner 12, simplifies the connection structure between the first and second liner 11, and thus simplifies the overall structure of functional plate 1.

[0149] Of course, the first end of the second liner 12 and the first liner 11 can also be rotatably connected by other structures, and are not limited to the crease structure.

[0150] In some embodiments, in the unsupported state, the second liner 12 is laid flat on the surface where the first liner 11 is located, with the second end of the second liner 12 away from the first liner 11, and the second end of the second liner 12 can rotate relative to the first end of the second liner 12 to a supported state. In this way, in the unsupported state, the entire functional panel 1 is located in the same surface, reducing the overall height of the functional panel 1, thereby facilitating the packaging, transportation, and storage of the functional panel 1.

[0151] In other embodiments, it is also possible to choose a non-supported state where the surface of the second liner 12 is different from the surface of the first liner 11, and it is not limited to the above embodiments.

[0152] In some embodiments, in the supported state, the second end of the second liner 12 is connected to the first liner 11. This effectively improves the stability of the second liner 12 in the supported state. To facilitate the connection between the second end of the second liner 12 and the first liner 11, the second liner 12 can be bent and deformed in the unsupported state. The second liner 12 reaches the supported state by rotating and bending relative to the first liner 11.

[0153] To facilitate bending and deformation of the second liner 12, the second liner 12 can be selected as a flexible plate or a bendable plate.

[0154] In the supported state, the shape of the second liner 12 is selected according to the actual situation. In some embodiments, in the supported state, when the second liner 12 can be bent and deformed, the second liner 12 has a bent structure, and the bent structure protrudes in a direction away from the first liner 11. This facilitates the connection between the second end of the second liner 12 and the first liner 11, and also facilitates the suspension of the fluid handling device. Exemplarily, the bent structure can be a smooth curved structure, a quadrilateral structure (e.g., a trapezoidal structure), a triangular structure, etc., and the specific shape of the bent structure is not limited in the embodiments of this application.

[0155] In practice, the bending structure can also be recessed towards the first liner 11, and is not limited to the structure described above.

[0156] As mentioned above, in the supported state, the second end of the second liner 12 is connected to the first liner 11. For ease of disassembly and maintenance, the second end of the second liner 12 and the first liner 11 can be detachably connected. To simplify the connection structure, the second end of the second liner 12 and the first liner 11 can be selected to snap-fit ​​(detachably snap-fit).

[0157] To facilitate the engagement of the second end of the second liner 12 with the first liner 11, one of the first liner 11 and the second liner 12 is provided with a first latching hole 114 formed by tearing along the tear line, and the other is provided with a first buckle 122 formed by tearing along the tear line. The first buckle 122 engages with the first latching hole 114. The first latching hole 114 and the first buckle 122 are formed by the tear line, which simplifies the structure of the first liner 11 and the second liner 12, and also facilitates the packaging, transportation and storage of the entire functional board 1.

[0158] Of course, it is possible to directly provide the first card hole 114 on one of the first liner 11 and the second liner 12 and the first buckle 122 on the other, and it is not limited to the way of forming by tearing open the easy-tear line; it is also possible to achieve the snap-fit ​​between the first liner 11 and the second liner 12 through other structures, and this application embodiment does not limit this.

[0159] In some other embodiments, in the supported state, the second end of the second liner 12 may not be connected to the first liner 11. This can be understood as the second end of the second liner 12 being farther away from the first liner 11 than its first end. This reduces the size of the first liner 11, thereby reducing the space required for the functional plate 1 in the supported state and the space required for the functional plate 1 in the unsupported state. Since the second end of the second liner 12 does not need to be connected to the first liner 11 in the supported state, the steps required for the second liner 12 to adjust from the unsupported state to the supported state are reduced, thus facilitating the movement of the second liner 12 from the unsupported state to the supported state.

[0160] To facilitate the support of the bubble filter 107 by the second liner 12, an angle may be formed between the second liner 12 and the first liner 11 in the supported state. In this case, both the second liner 12 and the first liner 11 are flat structures, and the second liner 12 may be rotated and folded relative to the first liner 11 to reach the supported state in the unsupported state.

[0161] Of course, it is possible to choose the supported state where the second liner 12 is a bent plate structure. In this case, it is possible to choose the unsupported state where the second liner 12 reaches the supported state by rotating and bending relative to the first liner 11.

[0162] To facilitate the support structure 121 in supporting the bubble filter 107, the support structure 121 can be positioned above the first end of the second liner 12 to suspend the bubble filter 107 in the supported state. This ensures that the bubble filter 107 is in a working position.

[0163] It should be noted that when the second liner 12 is in a non-supported state and the second liner 12 is laid flat on the surface where the first liner 11 is located, the support structure 121 is higher than the first liner 11 when the second liner 12 is in a supported state.

[0164] The above-mentioned support structure 121 suspends the bubble filter 107 in a manner that can be applied to the case where the second liner 12 is in a supported state and the second end of the second liner 12 is connected to the first liner 11, or it can be applied to the case where the second liner 12 is in a supported state and the second end of the second liner 12 is not connected to the first liner 11.

[0165] In practice, the support structure 121 can also be used to support the bubble filter 107 in other ways, such as by supporting the bubble filter 107 by means of bearing, and is not limited to the suspension method.

[0166] In some embodiments, in the supported state, the support structure 121 is located in the suspended portion of the second liner 12 to support the bubble filter 107. This suspended arrangement of the support structure 121 facilitates the placement of the bubble filter 107 on the support structure 121. Furthermore, it also facilitates suspending the bubble filter 107 on the support structure 121.

[0167] In practice, it is also possible to choose a supported state where the support structure 121 is located in the non-suspended part of the second liner 12. For example, the support structure 121 is located at the first end of the second liner 12. This application embodiment does not limit this.

[0168] In functional board 1, the specific structure of the support structure 121 is selected according to the actual situation. In some embodiments, the support structure 121 includes a first support structure 1211 and a second support structure 1212. The first support structure 1211 supports the first end of the bubble filter 107, and the second support structure 1212 supports the second end of the bubble filter 107. In this way, the first support structure 1211 and the second support structure 1212 cooperate to support the bubble filter 107, improving the support stability and thus facilitating the bubble filtration effect of the bubble filter 107.

[0169] As mentioned above, there are one or more support structures 121. Based on this, in one possible embodiment, the first support structure 1211 and the second support structure 1212 of at least one support structure 121 are disposed on the same second liner 12; in another possible embodiment, the first support structure 1211 and the second support structure 1212 of at least one support structure 121 are disposed on different second liner 12s.

[0170] The two possible implementation methods described above can be combined or implemented individually, and this application does not limit this. To improve the stability of the support structure 121, at least one first support structure 1211 and second support structure 1212 can be respectively disposed on different second liner plates 12. The second liner plates 12 on which the first support structure 1211 and the second support structure 1212 are respectively located are two adjacent second liner plates 12, which can be understood as: the first support structure 1211 and the second support structure 1212 are adjacent, thus facilitating the installation of the bubble filter 107 or other fluid processing devices.

[0171] Of course, it is possible to choose that the second liner 12 where the first support structure 1211 and the second support structure 1212 are located are not adjacent, and it is not limited to the above structure.

[0172] In the supported state, the first support structure 1211 and the second support structure 1212 can have a height difference, which can enable the bubble filter 107 to be placed in the vertical direction, or the placement direction of the bubble filter 107 to be tilted relative to the vertical direction, thereby ensuring that the bubble filter 107 is in the working posture.

[0173] In practice, such as Figure 14 As shown, one of the first support structure 1211 and the second support structure 1212 can be located directly below the other. This can be understood as the vertical projection of the first support structure 1211 and the vertical projection of the second support structure 1212 coinciding (partially or completely overlapping). To achieve this specific structure, combined with... Figure 12 As shown, there are multiple second liner plates 12. The first ends of the multiple second liner plates 12 are aligned, and the connection positions of the second ends and the first liner plates 11 are aligned. The lengths of the different second liner plates 12 are different. The first support structure 1211 and the second support structure 1212 are located at the length center positions of two adjacent and different second liner plates 12, respectively. The first support structure 1211 and the second support structure 1212 are both located between the two corresponding second liner plates 12. In this way, after the different second liner plates 12 are folded and rotated, the first support structure 1211 and the second support structure 1212 form a height difference, and the first support structure 1211 and the second support structure 1212 are located at the length center positions of the corresponding second liner plates 12, respectively. The projections of the first support structure 1211 and the second support structure 1212 in the vertical direction coincide.

[0174] The above structure allows the bubble filter 107 to be placed vertically. Based on the filtration principle of the bubble filter 107, this effectively improves the filtration efficiency of the bubble filter 107, thereby enhancing the rinsing effect of the rinsing pipe 100.

[0175] It should be noted that, Figure 14 The flow direction of the medium fluid through the bubble filter 107 can be from bottom to top, which facilitates the automatic upward flow of bubbles into the bubble filter and their filtration.

[0176] Of course, it is also possible to choose a situation where the projection of the first support structure 1211 in the vertical direction and the projection of the second support structure 1212 in the vertical direction do not overlap, so that the placement direction of the bubble filter 107 is relatively inclined to the vertical direction.

[0177] In the supported state, the first support structure 1211 and the second support structure 1212 can also be without a height difference. This can be understood as: in the supported state, the first support structure 1211 and the second support structure 1212 are set at the same height. In this way, the fluid processing device can be placed in a horizontal direction.

[0178] The distribution of the first support structure 1211 and the second support structure 1212 is designed according to the working posture required by the fluid processing device. This application embodiment does not make a selection in this regard.

[0179] In some embodiments, when the first support structure 1211 and the second support structure 1212 of at least one support structure 121 are respectively disposed on different second liner plates 12: the lengths of the second liner plates 12 on which the first support structure 1211 and the second support structure 1212 are respectively located are different, so that there is a height difference between the first support structure 1211 and the second support structure 1212 in the supported state. This facilitates the realization of a height difference between the first support structure 1211 and the second support structure 1212.

[0180] The specific positions of the first support structure 1211 and the second support structure 1212 in the second liner 12 are selected according to the actual situation. In order to ensure that a height difference is formed between the first support structure 1211 and the second support structure 1212, it can be selected that, in the supported state, the first support structure 1211 and the second support structure 1212 are respectively located at the top of the second liner 12 where they are located.

[0181] In the functional board 1 provided in this application embodiment, the first liner 11 may only be used to support the second liner 12, or the first liner 11 may also have other functions and roles.

[0182] In some embodiments, the first liner 11 is also used to house fluid delivery lines.

[0183] It should be noted that when the fluid delivery pipeline is not in operation, the first liner 11 is used to house the fluid delivery pipeline. When the fluid delivery pipeline is not in operation, it is not mounted on the flushing pump drive unit 01, which is a fluid-driven device. Therefore, the support structure 121 is used to support the fluid handling device detached from the fluid delivery pipeline of the first liner 11.

[0184] In the above embodiments, the first liner 11 is used to place the fluid delivery pipeline, thus the first liner 11 can serve as packaging, facilitating the transportation and storage of the fluid delivery pipeline. Moreover, the first liner 11 and the second liner 12 are connected, realizing the integration of packaging and support. That is, when transporting and storing the fluid delivery pipeline, the first liner 11 can fix the fluid delivery pipeline in place, and when using the fluid delivery pipeline, the first liner 11 can serve as a support for the second liner 12. This makes it convenient for users to place the fluid handling device with the fluid delivery pipeline detached from the first liner 11 on the support structure 121, which is conducive to the clinical application of the fluid delivery pipeline.

[0185] As described above, the fluid delivery line includes at least one of a flushing line 100 and an arterial pressure measurement line 200. When the fluid delivery line includes a flushing line 100, the first liner 11 also serves to hold the flushing line 100. Thus, after the flushing line 100 is removed from the first liner 11, the second end of the second liner 12 is moved towards the first end of the second liner 12 to a supported position, placing the fluid handling device of the flushing line 100 on the support structure 121 of the second liner 12. This facilitates support of the fluid handling device and promotes the clinical application of the flushing line 100.

[0186] Accordingly, when the fluid delivery line includes an arterial pressure measuring line 200, the first liner 11 is used to house the arterial pressure measuring line 200. The support structure 121 of the second liner 12 may or may not support the fluid handling device on the arterial pressure measuring line 200. For example, the support structure 121 of the second liner 12 may support the fluid handling device on the arterial pressure measuring line 200. In this way, after the arterial pressure measuring line 200 is removed from the first liner 11, the second end of the second liner 12 is moved towards the first end of the second liner 12 to a supported state, and the fluid handling device of the arterial pressure measuring line 200 is placed on the support structure 121 of the second liner 12. This facilitates the support of the fluid handling device and the clinical application of the arterial pressure measuring line 200.

[0187] In cases where the fluid delivery line includes a flushing line 100 and an arterial pressure measuring line 200, the first liner 11 is also used to house the flushing line 100 and the arterial pressure measuring line 200, which facilitates the support of the fluid device and makes the clinical application of the flushing line 100 and the arterial pressure measuring line 200 easier.

[0188] The specific structure of the first liner 11 is selected according to the actual situation. In some embodiments, the first liner 11 includes a first sub-plate 111 and a second sub-plate 112; wherein, the first sub-plate 111 is used to place the fluid delivery pipeline; the second sub-plate 112 is connected to the first sub-plate 111, the first end of the second liner 12 is connected to the second sub-plate 112, and the second sub-plate 112 is used to support the second liner 12 in a supported state. In this way, the two functions of the first liner 11 are achieved through different sub-plates, simplifying the structure of the first sub-plate 111 and the second sub-plate 112, thereby simplifying the overall structure of the first liner 11.

[0189] In the aforementioned functional board 1, in the unsupported state, the first sub-board 111 and the second liner 12 are distributed on opposite sides of the second sub-board 112. Of course, the first sub-board 111, the second sub-board 112, and the second liner 12 can also be distributed in other ways, and this embodiment does not limit this.

[0190] In the first liner 11, the second sub-plate 112 and the first sub-plate 111 are detachably connected, such that, Figure 13 and Figure 14 As shown, the second partition plate 112 can be separated from the first partition plate 111. The second liner plate 12 is supported only by the second partition plate 112. Compared with the second liner plate 11 supporting the second liner plate 12, the area of ​​the support part is effectively reduced, which facilitates the use of the functional plate 1.

[0191] To simplify the structure of the first liner 11, the second sub-plate 112 and the first sub-plate 111 can be detachably connected via an easy-tear line. It is understood that the connection point (sub-plate connection point 113) between the second sub-plate 112 and the first sub-plate 111 has an easy-tear line, which also facilitates the packaging, transportation, and storage of the entire functional panel 1. Of course, the second sub-plate 112 and the first sub-plate 111 can be detachably connected using other structures; this embodiment does not limit this approach.

[0192] In practice, the second plate 112 and the first plate 111 can be chosen to be inseparable. In this way, under the support state, the second plate 112 and the first plate 111 jointly support the second liner 12.

[0193] As mentioned above, the fluid transport pipeline includes a fluid transport pipe and a fluid device disposed on the fluid transport pipe, the fluid device including a fluid handling device. Accordingly, the first liner 11 is provided with a pipe placement structure 115 and a device placement structure 116. The pipe placement structure 115 is used to place the fluid transport pipe, and the device placement structure 116 is used to place the fluid device. When the first sub-plate 111 and the second sub-plate 112 are detachably connected, the pipe placement structure 115 and the device placement structure 116 can be selected to be both distributed on the first sub-plate 111.

[0194] In the aforementioned functional board 1, the first liner 11 is able to hold the fluid delivery pipe and fluid device, thereby improving the stability of the fluid delivery pipe placed on the first liner 11.

[0195] There can be one or more pipe placement structures 115, and one or more device placement structures 116. The specific number of pipe placement structures 115 and device placement structures 116 is selected according to the actual situation, and this application embodiment does not limit this.

[0196] The following uses a fluid delivery pipeline including a flushing pipeline 100 and an arterial pressure measuring pipeline 200 as an example to illustrate the pipe placement structure 115 and the device placement structure 116.

[0197] like Figure 11 and Figure 12As shown, in the first liner 11, there are five tube placement structures 115: one tube placement structure 115 is used to place the inlet tube 1011 of the flushing line 100, one tube placement structure 115 is used to place the outlet tube 1012 of the flushing line 100, one tube placement structure 115 is used to place the circulation tube 1013 of the flushing line 100, and two tube placement structures 115 are used to place the arterial pressure measuring tube 201 of the arterial pressure measuring line 200; there are six device placement structures 116: two device placement structures 116 are used to place the first puncture device 103 of the flushing line 100, two device placement structures 116 are used to place the connector 106 of the flushing line 100, and two device placement structures 116 are used to place the second puncture device 202 of the arterial pressure measuring line 200.

[0198] In practice, the number of pipe placement structures 115 and device placement structures 116 can be other, and device placement structures 116 can also hold other fluid devices, and are not limited to the above structures.

[0199] In cases where the fluid delivery line includes a flushing line 100 or an arterial pressure measurement line 200, the tube placement structure 115 and the device placement structure 116 may be appropriately adjusted, but this application embodiment does not limit this.

[0200] The specific structure of the pipe placement structure 115 is selected according to the actual situation. In some embodiments, the pipe placement structure 115 includes binding straps for securing the fluid delivery pipe. This facilitates the placement of the fluid delivery pipe and also improves the stability of the fluid delivery pipe on the first liner 11.

[0201] In one possible implementation, the binding strap can be formed by tearing the first liner 11 along the tear line, which simplifies the structure of the first liner 11 and facilitates the packaging, transportation and storage of the entire functional panel 1.

[0202] In another possible implementation, in order to simplify the structure of the first liner 11, the functional plate 1 may further include a binding strip 13. The first liner 11 is provided with a first mounting hole 117 and a second mounting hole 118. The binding strip 13 is used to connect to the first liner 11 through the first mounting hole 117 and the second mounting hole 118 to form a binding strap.

[0203] To facilitate the setting of the first mounting hole 117 and the second mounting hole 118, the first mounting hole 117 and the second mounting hole 118 can be formed by tearing the first liner 11 along the tear line. This also facilitates the packaging, transportation and storage of the entire functional board 1. Of course, the first mounting hole 117 and the second mounting hole 118 can be formed by directly drilling holes in the first liner 11.

[0204] The two possible implementation methods described above can be combined or implemented separately, depending on the actual situation. This application does not limit this approach.

[0205] To facilitate the binding of fluid delivery tubes with cable ties, a detachable cable tie can be selected. This makes it easier to insert and remove the fluid delivery tube. For detachable binding, one end of the cable tie can have a second locking hole 1151 formed by tearing along the easy-tear line, and the other end can have a second buckle 1152 formed by tearing along the easy-tear line. The second buckle 1152 engages with the second locking hole 1151.

[0206] In practice, cable ties can also be used to detachably bind fluid delivery pipes in other ways, and are not limited to the structure described above.

[0207] The specific structure of the device placement structure 116 is selected according to the actual situation. In some embodiments, the device placement structure 116 includes a support with a mounting groove for mounting the fluid device. In this way, the fluid device can be directly placed in the mounting groove, simplifying the placement of the fluid device and improving the ease of use of the first liner 11.

[0208] In practice, the fluid device can be positioned with its middle section within the support trench, both ends within the support trench, or both ends and the middle section within the support trench. To improve the stability of the fluid device, it can be selected that at least both ends of the fluid device are located within the support trench. In this case, at least two support trenches correspond to one fluid device.

[0209] To facilitate the formation of the support, it can be formed by tearing the first liner 11 along the tear line. This also facilitates the packaging, transportation, and storage of the entire functional panel 1. Of course, the support can be directly set on the first liner 11, and this embodiment does not limit this.

[0210] The aforementioned functional board 1 can be a PP board (polypropylene board) or other material board, and this embodiment does not limit it.

[0211] To facilitate the manufacturing and production of functional board 1, it can be selected as a die-cutting board. Of course, functional board 1 can also be selected as other types, and this embodiment does not limit this.

[0212] The functional board 1 provided in this application embodiment has the above-mentioned technical effects. The fluid pipeline assembly provided in this application embodiment includes the above-mentioned functional board 1, so the fluid pipeline assembly provided in this application embodiment also has the corresponding technical effects, which will not be repeated here.

[0213] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
