Description

Technical Field

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

[0002] A multichannel infusion pump is an injection device used in the medical industry. It can accurately deliver medications into the patient's body by controlling parameters such as the flow rate and volume of the solution, effectively treating various diseases.

[0003] Existing multichannel injection pumps typically include a drive assembly, an injection cylinder, and multiple piston components. The injection cylinder has multiple receiving channels, and the piston heads of each piston component are correspondingly located within these channels. The push-pull heads of all piston components are connected to the output end of the booster assembly. During operation, the drive assembly moves all piston components, causing the piston heads of each piston component to generate suction or pressure on their respective receiving channels, thus achieving the purpose of multichannel aspiration of the drug solution.

[0004] However, due to the uncertainty of the number of samples being processed in actual use, it is necessary to select individual channels that do not require operation. Existing multi-channel syringe pumps, on the other hand, must operate simultaneously and cannot select individual channels to be inactive, thus lacking flexibility. Utility Model Content

[0005] Based on the above description, this utility model provides a multi-channel injection pump, which aims to solve the problem that existing multi-channel injection pumps cannot select individual channels that are not working.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] Support plate, having a first sidewall;

[0009] The drive assembly is mounted on the support plate;

[0010] An injection assembly includes a multi-channel syringe, connectors, and a slide plate arranged sequentially along a first direction. The number of connectors is related to the number of receiving channels of the multi-channel syringe. All connectors are disposed on the slide plate. Each connector corresponds to a piston rod of the multi-channel syringe. The slide plate is connected to the output end of the drive assembly.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the support plate has a second sidewall disposed opposite to the first sidewall, and the support plate has a through hole extending from the first sidewall toward the second sidewall and penetrating the second sidewall. The drive assembly is disposed on the second sidewall, and one end of the slide plate passes through the through hole and is connected to the output end of the drive assembly.

[0013] Furthermore, the drive assembly includes a drive motor, a lead screw, and a nut seat. One end of the lead screw is connected to the output end of the drive motor, and the nut seat is threadedly connected to the lead screw. A first mounting hole is provided on the slide plate, and the nut seat is installed in the first mounting hole.

[0014] Furthermore, the connector is an electromagnet.

[0015] Furthermore, the connector is a clamp.

[0016] Furthermore, the slide plate has a receiving slot for each electromagnet, and the electromagnets are respectively disposed in the receiving slots.

[0017] Furthermore, it includes at least one pair of guide components, each pair of guide components being axially symmetrical about the axis of the lead screw, the slide plate having a second mounting hole corresponding to the guide component, the guide component including a support member and a sliding member, the sliding member being movably disposed on the support member, and the sliding member being installed within the second mounting hole.

[0018] Furthermore, it includes a pair of light sensors, which are spaced apart along the first direction on the second sidewall, and each light sensor is disposed opposite to the driving component.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0020] (1) This utility model can determine the working receiving channel according to actual needs, and connect it to the piston rod of the multi-channel syringe through the connecting piece corresponding to the working receiving channel.

[0034] Reference Figures 1-2 As shown, this utility model provides a technical solution: a multi-channel injection pump, including a support plate 10, a drive assembly 20, and an injection assembly 30. The support plate 10 has a first sidewall 11; the drive assembly 20 is disposed on the support plate 10; the injection assembly 30 includes a multi-channel syringe 31, a connector 32, and a slide plate 33 arranged sequentially along a first direction. The number of connectors 32 is related to the number of receiving channels 311 of the multi-channel syringe 31. All connectors 32 are disposed on the slide plate 33. Each connector 32 corresponds to a piston rod of the multi-channel syringe 31. The slide plate 33 is connected to the output end of the drive assembly 20.

[0035] For example, the support plate 10 can be configured as an L-shape, etc.; the drive assembly 20 can be disposed on the horizontal plate of the support plate 10. The drive assembly 20 can be a cylinder, a hydraulic cylinder, or a linear motor, etc.

[0036] In this embodiment, after the partial receiving channel 311 is designated as the working receiving channel 311, the connecting member 32 corresponding to the working receiving channel 311 is connected to the piston rod of the multi-channel syringe 31. The driving assembly 20 drives the slide plate 33 to move along the first direction, so that the slide plate 33 drives the extrusion head of the piston member 32 to move along the first direction to realize liquid aspiration and injection.

[0037] Reference Figures 1-2 As shown, in some embodiments, the support plate 10 has a second side wall 12 disposed opposite to the first side wall 11. The support plate 10 has a through hole extending from the first side wall 11 toward the second side wall 12 and penetrating the second side wall 12. The drive assembly 20 is disposed on the second side wall 12. One end of the slide plate 33 passes through the through hole and is connected to the output end of the drive assembly 20.

[0038] In this embodiment, by setting the drive component 20 and the injection component 30 opposite to each other, the operating space of the injection component 30 can be avoided, thereby facilitating the user to perform cleaning or maintenance operations on the injection component 30.

[0039] Reference Figures 1-2As shown, in some embodiments, the drive assembly 20 includes a drive motor 21, a lead screw 22 and a nut seat 23. One end of the lead screw 22 is connected to the output end of the drive motor 21, and the nut seat 23 is threadedly connected to the lead screw 22. A first mounting hole 331 is provided on the slide plate 33, and the nut seat 23 is installed in the first mounting hole 331.

[0040] In this embodiment, the drive motor 21 drives the lead screw 22 to rotate, which enables the nut seat 23 to provide power to the slide plate 33 so as to realize the movement of the slide plate 33 along the first direction.

[0041] In some embodiments, the connector 32 is an electromagnet.

[0042] For example, the piston rod of the multi-channel syringe 31 can be made of metal, or an electromagnet or the like can be provided at the end of the piston rod of the multi-channel syringe 31 away from the piston.

[0043] In this embodiment, after a portion of the receiving channel 311 is designated as the working receiving channel 311, the connecting member 32 corresponding to the working receiving channel 311 is attracted to the piston rod of the multi-channel syringe 31. This allows the slide plate 33 to drive the piston rod of the multi-channel syringe 31 corresponding to the working receiving channel 311 to operate when the slide plate 33 moves along the first direction.

[0044] In other embodiments, the connector 32 is a clamp.

[0045] For example, the clamp can be a pneumatic gripper or an electric gripper.

[0046] In this embodiment, after the partial receiving channel 311 is determined as the working receiving channel 311, the connecting member 32 corresponding to the working receiving channel 311 clamps the piston rod of the multi-channel syringe 31, so that when the slide plate 33 moves along the first direction, the slide plate 33 can drive the piston rod of the multi-channel syringe 31 corresponding to the working receiving channel 311 to work.

[0047] Reference Figures 1-2 As shown, in some embodiments, the slide plate 33 has a receiving slot 333 for each electromagnet, and the electromagnets are respectively disposed in the receiving slots 333.

[0048] In this embodiment, the receiving groove 333 serves to position the electromagnet, which not only facilitates the alignment of the electromagnet with the piston rod of the multi-channel syringe 31, but also facilitates the assembly of the electromagnet.

[0049] Reference Figures 1-2As shown, in some embodiments, the multichannel injection pump includes at least one pair of guide components 40, each pair of guide components 40 being axially symmetrical about the axis of the lead screw 22. The slide plate 33 has a second mounting hole 332 corresponding to the guide component 40. The guide component 40 includes a support member 41 and a slider 42. The slider 42 is movably disposed on the support member 41 and is installed within the second mounting hole 332.

[0050] For example, the support member 41 can be a guide rod or optical axis, and the sliding member 42 can be a guide sleeve or linear bearing, etc.; when the support member 41 is a guide rod, the sliding member 42 is a guide sleeve; when the support member 41 is an optical axis, the sliding member 42 is a linear bearing.

[0051] In this embodiment, when the slide plate 33 moves along the first direction, the sliding member 42 slides along the support member 41, which can ensure the stability of the movement of the slide plate 33.

[0052] Reference Figures 1-2 As shown, in some embodiments, the multichannel injection pump includes a pair of light sensors 50, which are spaced apart along a first aspect on a second sidewall 12, and each light sensor 50 is disposed opposite to the drive assembly 20.

[0053] In this embodiment, the slide plate 33 can have a first position and a second position. The first position can be the position when the receiving channel 311 is empty of medicine, and the second position can be the position when the receiving channel 311 is filled with medicine. Based on this, one photosensitive sensor 50 can correspond to the first position, and the other photosensitive sensor 50 can correspond to the second position. By detecting the position of the slide plate 33 through a pair of photosensitive sensors 50, it is possible to know whether the receiving channel 311 has medicine or whether the receiving channel 311 is filled with medicine.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
