Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a multi-channel infusion set. Background Technology

[0002] In current PCI (percutaneous coronary intervention) procedures, there is a risk of thrombosis within the vascular sheath. Currently, manual injection is used, infusing medication into the lumen through sheath side branches to flush the lumen. However, manual operation is inconvenient for the operator, especially with multiple puncture sites. Infusing medication at each puncture site prolongs the procedure and increases the risk of thrombosis. To improve efficiency and meet clinical needs, the use of multi-channel infusion sets for simultaneous medication infusion at multiple puncture sites is an essential research topic. However, current methods cannot simultaneously deliver the same medication to multiple puncture sites, nor can they selectively infuse medication at specific sites, or control the flow rate of medication at each puncture site. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a multi-channel infusion set that can simultaneously infuse medication into the vascular sheaths of multiple puncture points, preventing thrombosis and improving surgical efficiency. It allows for selective infusion into only some puncture points and enables adjustment and control of the drug flow rate at each output section, making the amount of medication infused into different puncture points more reasonable.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A multi-channel infusion set includes an input section, a connecting section, and multiple output sections connected in sequence. The connecting section includes a connecting tube, multiple connecting sub-connectors, and multiple regulating valves. One end of the input section is connected to an infusion bottle, and the other end is connected to the connecting tube. The multiple connecting sub-connectors are connected to the connecting tube through multiple regulating valves. The regulating valves can cut off or open the passage between the connecting tube and the connecting sub-connectors by rotation. The output section includes a branch tube, a drip chamber, and a speed regulator. The multiple branch tubes of the multiple output sections are respectively connected to the multiple connecting sub-connectors. The end of the branch tube away from the connecting sub-connector is connected to a vascular sheath. The branch tube is provided with a drip chamber and a speed regulator in sequence.

[0006] As a further improvement to the above technical solution:

[0007] The branch pipe has a branch pipe inlet connector at one end near the connecting pipe, and the branch pipe inlet connector and the connecting sub-connector are detachably connected.

[0008] The connecting part also includes auxiliary components, on which the connecting pipe is mounted.

[0009] The input section includes a main pipeline and a main drip chamber and a main speed controller installed on the main pipeline. One end of the main pipeline is equipped with a puncture needle for puncturing the infusion bottle, and the other end is connected to a connecting tube.

[0010] A main pipe output connector is provided at the end of the main pipe near the connecting pipe, and a connecting main connector is provided at the end of the connecting pipe near the main pipe. The main pipe output connector and the connecting main connector are detachably connected.

[0011] The main outlet connector is an inner tapered connector, and the connecting main connector is an outer tapered connector.

[0012] By rotating a regulating valve to different states, the connecting pipe can be connected to the corresponding connecting sub-connector of the regulating valve, or the connecting pipe can be connected to the external environment through the regulating valve, or the connecting pipe can be neither connected to the corresponding connecting sub-connector of the regulating valve nor connected to the external environment through the regulating valve.

[0013] The regulating valve includes a valve body and a flow divider. One end of the valve body is mounted on a connecting pipe, and the other end is connected to the flow divider. The flow divider is rotatably mounted on the valve body. The valve body has a straight through hole, and the flow divider has an L-shaped through hole. One end of the flow divider can be inserted into the through hole of the valve body, so that the L-shaped through hole of the flow divider connects to the through hole of the valve body. The liquid in the connecting pipe enters the valve body and then enters the L-shaped through hole of the flow divider from the through hole of the valve body. When the flow divider is adjusted to rotate relative to the valve body, one part of the L-shaped through hole of the flow divider rotates on its own axis, and the other part rotates around the through hole of the valve body. This ensures that one inlet and outlet of the L-shaped through hole of the flow divider is always located in the through hole of the valve body, while the other inlet and outlet face different directions, causing the liquid flowing out of the L-shaped through hole of the flow divider to flow in different directions.

[0014] One end of the valve body's through-hole is the inlet, and the other end is for the distributor to be inserted. The middle side wall of the valve body has three outlets, which are connected to the through-hole of the valve body. The distributor has an L-shaped through-hole at one end that is inserted into the through-hole of the valve body, and the other end is connected to the handle. The handle is not inserted into the through-hole of the valve body. After the distributor is inserted into the through-hole of the valve body, one part of the L-shaped through-hole of the distributor is connected to the through-hole of the valve body, and the other part is connected to the outlet or blocked by the side wall of the valve body to achieve flow interception.

[0015] The beneficial effects of this utility model are:

[0016] (1) Drug infusion can be performed on the vascular sheaths of multiple puncture sites at the same time to prevent thrombosis. During the operation, simultaneous drug delivery can improve the efficiency of the operation and reduce additional harm to the patient.

[0017] (2) Each output section is controlled by a regulating valve, which allows selection of the vascular sheath for drug infusion. That is, drug infusion can be selected for some puncture sites, and among all puncture sites, drug infusion can be performed on the vascular sheaths that require drug infusion, while drug infusion can be left untreated, thus increasing the operability of the surgery. The regulating valve does not affect the opening and closing of the connecting tube.

[0018] (3) Each output section is equipped with a drip chamber and a speed controller, which can adjust and control the flow rate of the drug infused in each output section. The flow rate of the drug infused in a single channel or multiple channels can be accurately controlled, so that the amount of drug infused at different puncture points is more reasonable.

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] A multi-channel infusion set, such as Figures 1-3 As shown, it includes an input section, a connecting section and multiple output sections connected in sequence. One end of the input section is connected to the infusion bottle 10 and the other end is connected to the connecting section. The input section delivers the fluid in the infusion bottle 10 to the connecting section. The connecting section can controllably deliver the fluid to the vascular sheath through at least one output section. The vascular sheath is a vascular puncture sheath used to puncture the patient's skin to establish a basic pathway from the skin to the blood vessel.

[0030] Input section, such as Figure 2 As shown, the system includes a main tubing 11 and a main drip chamber 12 and a main speed controller 13 mounted on the main tubing 11. One end of the main tubing 11 is equipped with a puncture needle 14 for inserting the stopper of the infusion bottle 10, and the other end is equipped with a main tubing output connector 15. The puncture needle 14, the main drip chamber 12, the main speed controller 13, and the main tubing output connector 15 are sequentially arranged on the main tubing 11. The infusion bottle 10 contains physiological saline, glucose solution, etc.

[0031] Connecting parts such as Figure 3 As shown, it includes a connecting pipe 21, an auxiliary component 25, multiple regulating valves 22, and multiple connecting sub-connectors 24. One end of the connecting pipe 21 is provided with a main connecting connector 23, and the main pipe output connector 15 and the main connecting connector 23 are detachably connected to realize the connection between the connecting pipe 21 and the main pipeline 11.

[0032] Multiple connecting sub-connectors 24 are connected to and communicate with the connecting pipe 21 through multiple regulating valves 22. The regulating valves 22 act as switches; by manually controlling the regulating valves 22, the passage between the connecting pipe 21 and the connecting sub-connectors 24 can be closed or opened, thus ensuring that each connecting sub-connector 24 is independent and does not affect others. Therefore, the connecting pipe 21 is connected to the connecting sub-connectors 24, and the connecting pipe 21 serves as the infusion flow channel for the connecting section. The connecting sub-connectors 24 are connected to the inlet connectors 34 of each branch pipe, serving as the infusion flow channel for each branch.

[0033] The connecting pipe 21 is mounted on the auxiliary component 25. The auxiliary component 25, connecting pipe 21, and connecting sub-connector 24 form a single integral component: the main body of the connecting plate. The auxiliary component 25 is a rigid plate structure, which facilitates the support of the connecting pipe 21 and connecting sub-connector 24, and ensures stable force when controlling the regulating valve 22, providing stable support for the regulating valve 22 and facilitating manual control of the regulating valve 22. In other words, the auxiliary component 25 provides support and fixation for the connecting pipe 21 and connecting sub-connector 24, while also fitting tightly with the regulating valve 22, resulting in a stable structure and reducing the likelihood of leakage. Preferably, the auxiliary component 25 is made of hollow plastic, polymer, or other materials to minimize its weight.

[0034] regulating valve 22 Figures 4-6 As shown, the device includes a valve body 221 and a distributor 222, with the distributor 222 rotatably mounted on the valve body 221. The valve body 221 has a straight through-hole. The distributor 222 has an L-shaped through-hole, consisting of two perpendicularly connected sections. One end of the distributor 222 can be inserted into the through-hole of the valve body 221, allowing the L-shaped through-hole of the distributor 222 to connect with the through-hole of the valve body 221, with one section of the L-shaped through-hole of the distributor 222 coaxial with the through-hole of the valve body 221. The valve body 221 can be mounted on a connecting pipe 21 via a tee connector or similar component. In this way, liquid in the connecting pipe 21 enters the valve body 221 and then flows from the through-hole of the valve body 221 into the L-shaped through-hole of the distributor 222. When the distributor 222 is adjusted to rotate relative to the valve body 221, one section of the L-shaped through-hole of the distributor 222 rotates on its own axis, while the other section rotates around the through-hole of the valve body 221. In other words, when the diverter 222 rotates, one inlet and outlet of the L-shaped through-hole are always located within the through-hole of the valve body 221, while the other inlet and outlet face different directions, causing the liquid flowing out of the L-shaped through-hole to flow in different directions. Furthermore, by setting a blockage at a designated location, the outlet of the L-shaped through-hole of the diverter 222 can be blocked to achieve flow interception. The above-mentioned configuration of the regulating valve 22 does not affect the opening and closing of the overall passage of the connecting pipe 21.

[0035] In this embodiment, as Figure 5 and 6As shown, one end of the through hole of valve body 221 is an inlet 2211, and the other end is for insertion of the diverter 222. Three outlets 2212 are provided on the middle side wall of valve body 221, and these three outlets 2212 are connected to the through hole of valve body 221. One end of the diverter 222, which has an L-shaped through hole, is inserted into the through hole of valve body 221, and the other end is connected to a handle 223. The handle 223 is not inserted into the through hole of valve body 221. After the diverter 222 is inserted into the through hole of valve body 221, one section of the L-shaped through hole of the diverter 222 is connected to the through hole of valve body 221, and the other section is connected to the outlet 2212 (e.g., ...). Figure 5 (as shown) or blocked by the side wall of valve body 221 to achieve flow interception (e.g. Figure 6 (As shown). Thus, by rotating the splitter 222 using the control handle 223, the L-shaped through-hole of the splitter 222 is controlled to either connect to the outlet 2212 or be blocked.

[0036] In this embodiment, when the connecting pipe 21 is perpendicular to the horizontal plane, the three outlets 2212 of each regulating valve 22 face left, right, and downward, respectively, leaving one direction as upward. Left and right are two opposite directions that are essentially on the same horizontal plane, while upward and downward are two opposite directions perpendicular to the horizontal plane. The valve body 221 end face is provided with three small arrows 2213, as shown... Figure 4 As shown, there are three outlets 2212 respectively. A large arrow 2221 is provided on the handle 223. The positional relationship between the large arrow 2221 and the small arrow 2213 is set as follows: when the large arrow 2221 on the handle 223 and the small arrow 2213 on the valve body 221 are aligned, it means that the outlet 2212 corresponding to the small arrow 2213 is connected to the L-shaped through hole on the diverter 222; when the large arrow 2221 on the handle 223 points upward, that is, it is not aligned with any of the small arrows 2213, the outlet of the L-shaped through hole of the diverter 222 is blocked by the side wall of the valve body 221, thus achieving flow interception.

[0037] Based on the above structure, one of the three outlets 2212 is connected to the connecting sub-connector 24, while the other two outlets 2212 are not connected to any components, meaning they are directly connected to the external environment. Thus, when the L-shaped through-hole of the diverter 222 is connected to these two outlets directly connected to the external environment, excess liquid in the output and input sections can be quickly discharged and used for cleaning. Obviously, the other two outlets 2212 can also be detachably connected to a conduit to guide waste liquid or cleaning wastewater to a collection container. Therefore, "connected to the external environment" as described in this solution can be understood as connected to the external atmospheric environment or to other designated containers or specific environments.

[0038] It should be noted that the components of the regulating valve 22 can be configured as hollow structures without affecting the function, so as to reduce its weight to the greatest extent.

[0039] Based on the above structure, in this embodiment, the regulating valve 22 is a rotary valve. The main pipe output connector 15 is an inner conical connector, the connecting main connector 23 is an outer conical connector, and the connecting sub-connector 24 is an inner conical connector.

[0040] Output section such as Figure 7 As shown, the system includes a branch pipe 31, a drip chamber 32, and a speed controller 33. One end of the branch pipe 31 has a branch pipe inlet connector 34, and the other end has a branch pipe outlet connector 35. The branch pipe inlet connector 34 and the connecting sub-connector 24 are detachably connected, allowing the branch pipe 31 to communicate with the connecting pipe 21. The branch pipe outlet connector 35 and the vascular sheath are detachably connected, allowing the branch pipe 31 to communicate with the vascular sheath. The branch pipe 31 is sequentially equipped with a drip chamber 32 and a speed controller 33, and the branch pipe inlet connector 34, drip chamber 32, speed controller 33, and branch pipe outlet connector 35 are arranged sequentially. Clearly, the multiple branch pipes 31 of multiple outlet sections are connected to multiple connecting sub-connectors 24, achieving independence for each outlet section.

[0041] In this embodiment, the branch pipe inlet connector 34 is an external tapered connector.

[0042] In this embodiment, there are three output sections, and correspondingly, the connecting section is provided with three regulating valves 22 and three connecting sub-connectors 24.

[0043] It should be noted that both the main dripping funnel 12 and the individual dripping funnel 32 are structures used to observe the fluid delivery rate in the corresponding pipeline, and contain filters to remove particles from the solution; existing structures can be used. Both the main speed controller 13 and the individual speed controller 33 are structures used to adjust the delivery rate in the corresponding pipeline; existing structures can be used.

[0044] Based on the above structure, the puncture needle 14 is inserted into the infusion bottle 10. Using gravity or external pressure, the internal pressure of the infusion set is made higher than the blood pressure, thereby infusing the drug into the lumen of the vascular sheath. Specifically, the drug (physiological saline, glucose solution, etc.) in the infusion bottle 10 flows into the connecting tube 21 through the main tubing 11, and then is distributed to each output section through the regulating valve 22. The regulating valve 22 of the connecting section controls the flow and switching of each branch infusion channel (output section), and the flow rate of each branch infusion channel is controlled by the branch speed controller (sub-speed controller 33). During the process, the flow rate in the main tubing 11, i.e., the total flow rate, can be controlled by the main speed controller 13, and the infusion flow rate of the main tubing 11 can be observed through the main drip chamber 12. If infusion needs to be performed at several puncture points simultaneously, the corresponding regulating valves 22 are opened. Based on the drug infusion requirements of each puncture point, adjust each speed controller 33 to control the infusion flow rate of each branch infusion channel.

[0045] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
