Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a stop-fluid clamp control mechanism and an infusion pump. Background Technology

[0002] A stop clamp control mechanism is a control mechanism used in infusion pumps to control the opening and closing of the stop clamp, preventing accidental infusion of fluid to the patient when medical staff remove the infusion tubing from the pump. Existing stop clamp control mechanisms for infusion pumps are complex in structure, costly, and have low reliability. Summary of the Invention

[0003] In view of this, the present invention proposes a liquid stop clamp control mechanism and an infusion pump.

[0004] The first aspect of this invention provides a stop clamp control mechanism for use in an infusion pump to control the closing and opening of a stop clamp. The stop clamp control mechanism includes a housing assembly and a control assembly. The housing assembly is provided with a receiving space and an installation port. The stop clamp is inserted into the receiving space through the installation port. The receiving space has a first side in the width direction and a second side opposite to the first side. The direction in which the stop clamp is inserted into the receiving space is the length direction of the receiving space. The arrangement direction of the two side walls of the receiving space with a smaller distance is the thickness direction of the receiving space. The width direction is perpendicular to the length direction and the thickness direction.

[0005] The control component includes:

[0006] The clamping arm includes a connecting part and a pressing part. The connecting part is rotatably or slidably connected to the housing assembly, and the pressing part is disposed on the first side of the accommodating space.

[0007] A first elastic element is mounted on the housing assembly and abuts against the clamping arm to provide an elastic force so that the pressing part presses against the liquid stop clamp located in the accommodating space, thereby keeping the liquid stop clamp closed.

[0008] The unlocking arm includes a mating part and an unlocking part. The mating part is mechanically coupled to the connecting part. The unlocking part is disposed on the second side of the accommodating space. When subjected to external force, the unlocking part drives the mating part to move, thereby driving the connecting part of the clamping arm to move away from the liquid stop clamp so that the liquid stop clamp can be opened.

[0009] The second aspect of this invention provides a stop clamp control mechanism for use in an infusion pump to control the closing and opening of a stop clamp. The stop clamp control mechanism includes a housing assembly and a stop clamp presence detection assembly. The housing assembly is provided with a receiving space and a mounting port. The stop clamp is inserted into the receiving space through the mounting port. The stop clamp presence detection assembly includes:

[0010] A structural component, movably mounted to the housing assembly and extending partially into the accommodating space;

[0011] A magnet is connected to the structural component. The magnet has a first position and a second position relative to the Hall sensor disposed in the infusion pump as the structural component moves. The magnet is used to enable the Hall sensor to detect the change in magnetic flux when switching between the first position and the second position, so that the Hall sensor can detect the position of the magnet. When the accommodating space is equipped with a liquid stop clamp, the liquid stop clamp abuts against the structural component, so that the magnet is in the second position.

[0012] A reset component is connected to the structural component. The reset component is used to apply a reset force so that when the accommodating space is not equipped with a liquid stop clamp, the magnet is reset to the first position.

[0013] The third aspect of this invention provides a stop clamp control mechanism for use in an infusion pump to control the closing and opening of a stop clamp. The stop clamp control mechanism includes a housing assembly and a control assembly. The housing assembly is provided with a receiving space and an installation port. The stop clamp is inserted into the receiving space through the installation port. The receiving space has a first side in the width direction and a second side opposite to the first side. The direction in which the stop clamp is inserted into the receiving space is the length direction of the receiving space. The arrangement direction of the two side walls of the receiving space with a smaller distance is the thickness direction of the receiving space. The width direction is perpendicular to the length direction and the thickness direction.

[0014] The control component includes:

[0015] The clamping arm includes a connecting part and a pressing part. The connecting part is rotatably or slidably connected to the housing assembly, and the pressing part is disposed on the first side of the accommodating space.

[0016] A first elastic element is mounted on the housing assembly and abuts against the clamping arm to provide an elastic force so that the pressing part presses against the liquid stop clamp located in the accommodating space, thereby keeping the liquid stop clamp closed.

[0017] The unlocking arm is an integral structure with the clamping arm. The unlocking arm includes a mating part and an unlocking part. The unlocking part is disposed on the first side of the accommodating space. When subjected to external force, the unlocking part drives the mating part to move, thereby driving the connecting part of the clamping arm to move away from the liquid stop clamp, so that the liquid stop clamp can be opened.

[0018] The infusion pump proposed in the fourth aspect of the present invention includes:

[0019] Main body;

[0020] A switch cover, rotatably connected to the main body, having an open and closed state relative to the main body, and the switch cover being provided with a beveled portion and a protrusion; and

[0021] The aforementioned liquid-stopping clamp control mechanism is mounted on the main body.

[0022] During the process of the switch cover rotating from the open state to the closed state, the inclined surface abuts against and pushes the unlocking part, the unlocking part drives the connecting part of the clamping arm to move, so as to drive the pressing part of the clamping arm to move away from the liquid stop clamp, while the protrusion presses the liquid stop clamp, causing the two clamping arms of the liquid stop clamp to spring open.

[0023] The infusion pump proposed in the fifth aspect of the present invention comprises:

[0024] include:

[0025] Main body;

[0026] A switch cover, rotatably connected to the main body, having an open and closed state relative to the main body, and the switch cover being provided with a beveled portion and a protrusion; and

[0027] A liquid-stop clamp control mechanism is installed on the main body. The liquid-stop clamp control mechanism includes a housing assembly and a control assembly. The housing assembly is provided with a receiving space and a mounting port. The liquid-stop clamp is inserted into the receiving space through the mounting port. The control assembly includes:

[0028] A clamping arm, including a connecting portion and a pressing portion, wherein the connecting portion is rotatably or slidably connected to the housing assembly; and

[0029] A first elastic element is mounted on the housing assembly and abuts against the clamping arm to provide an elastic force so that the pressing part presses against the liquid stop clamp located in the accommodating space, thereby keeping the liquid stop clamp closed.

[0030] During the process of rotating the switch cover from the open state to the closed state, the inclined surface abuts against and pushes the pressing part, causing the pressing part to move away from the liquid stop clamp, while the protrusion presses the liquid stop clamp, causing the two clamping arms of the liquid stop clamp to spring open.

[0031] The infusion pump proposed in the sixth aspect of the present invention includes a main body, a stop clamp control mechanism, and a Hall sensor. The stop clamp control mechanism is installed in the main body and is used to control the closing and opening of the stop clamp. The stop clamp control mechanism includes a housing assembly and a stop clamp presence detection assembly. The housing assembly is provided with a receiving space and a mounting port. The stop clamp is inserted into the receiving space through the mounting port. The stop clamp presence detection assembly includes:

[0032] A structural component, movably mounted to the housing assembly and extending partially into the accommodating space;

[0033] A magnet is connected to the structural member. The magnet has a first position and a second position relative to the Hall sensor as the structural member moves. The Hall sensor is used to detect the position of the magnet by detecting the change in magnetic flux when the magnet is in the first position and the second position. When the accommodating space is equipped with a liquid stop clamp, the liquid stop clamp abuts against the structural member, so that the magnet is in the second position.

[0034] A reset component is connected to the structural component. The reset component is used to apply a reset force so that when the accommodating space is not equipped with a liquid stop clamp, the magnet is reset to the first position.

[0035] As can be seen from the above technical solutions, the liquid-stopping clamp control mechanism proposed in the first aspect of the present invention, by setting the control components including a clamping arm, a first elastic element, and an unlocking arm, can control the closing and opening of the liquid-stopping clamp through the cooperation of the clamping arm, the first elastic element, and the unlocking arm. The structure is simple and can effectively reduce costs and improve reliability. Furthermore, by setting the pressing part on the first side of the accommodating space and the unlocking part on the second side of the accommodating space, this layout can effectively reduce the thickness of the liquid-stopping clamp control mechanism, thereby reducing the space occupied by the liquid-stopping clamp control mechanism within the infusion pump.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figure 1 and Figure 2As shown, the stop clamp 200 is a common accessory of the infusion pump 1000, which clamps the infusion tubing 300 to prevent the flow of liquid within the tubing 300. A typical stop clamp 200 includes a first clamping arm 210, a second clamping arm 220, and a spring arm 230. One end of the first clamping arm 210 and one end of the second clamping arm 220 are connected by the spring arm 230, which provides the force to spring the first clamping arm 210 and the second clamping arm 220 apart. The end of the first clamping arm 210 away from the spring arm 230 has a first latching portion 240, and the end of the second clamping arm 220 away from the spring arm 230 has a second latching portion 250. The second latching portion 250 engages with the first latching portion 240 to keep the first clamping arm 210 and the second clamping arm 220 clamping the infusion tubing 300 in a closed state.

[0050] like Figures 2 to 5 As shown, an embodiment of the present invention provides a stop-fluid clamp control mechanism 100, which is used in an infusion pump 1000 to control the closing and opening of a stop-fluid clamp 200. When the stop-fluid clamp 200 is closed, it clamps the infusion tubing 300, cutting off the fluid flow path within the tubing, preventing medication or nutritional solutions from being delivered to the patient. When the stop-fluid clamp 200 is opened, it releases the clamped portion of the infusion tubing 300, allowing the fluid flow path within the tubing to reopen, enabling medication or nutritional solutions to flow through the fluid flow path to the needle and be injected into the patient.

[0051] The proposed liquid-stopping clamp control mechanism 100 includes a housing assembly 10 and a control assembly 20. The liquid-stopping clamp control mechanism 100 is installed on the main body 400 of the infusion pump 1000 through the housing assembly 10. The housing assembly 10 is provided with a receiving space 11 and a mounting port 12. The liquid-stopping clamp 200 is inserted into the receiving space 11 through the mounting port 12. The receiving space 11 has a first side and a second side opposite to the first side in the width direction X. The direction in which the liquid-stopping clamp 200 is inserted into the receiving space 11 is the length direction Y of the receiving space 11. The arrangement direction of the two side walls of the receiving space 11 with the smaller distance is the thickness direction Z of the receiving space 11. The width direction X is perpendicular to the length direction Y and the thickness direction Z.

[0052] The control assembly 20 includes a clamping arm 21, a first elastic member 22, and an unlocking arm 23. The clamping arm 21 includes a connecting portion 211 and a pressing portion 212. The connecting portion 211 is rotatably connected to the housing assembly 10, and the pressing portion 212 is disposed on the first side of the accommodating space 11. The first elastic member 22 is mounted on the housing assembly 10 and abuts against the clamping arm 21 to provide elastic force so that the pressing portion 212 presses the anti-liquid clamp 200 located in the accommodating space 11, thereby keeping the anti-liquid clamp 200 closed. The unlocking arm 23 includes a mating portion 231 and an unlocking portion 232. The mating portion 231 is mechanically coupled to the connecting portion 211, and the unlocking portion 232 is disposed on the second side of the accommodating space 11. When subjected to external force, the unlocking portion 232 drives the mating portion 231 to move, thereby driving the connecting portion 211 of the clamping arm 21 to move the pressing portion 212 of the clamping arm 21 away from the anti-liquid clamp 200, so that the anti-liquid clamp 200 can be opened.

[0053] It should be noted that "mechanical coupling between mating part 231 and connecting part 211" includes both mating part 231 and connecting part 211 being two independently configured parts with mechanical coupling, such as direct or indirect contact. It also includes mating part 231 and connecting part 211 being an integral structure. An integral structure includes both mating part 231 and connecting part 211 being two parts of a single component, and mating part 231 and connecting part 211 being two independently configured parts assembled together by mechanical connection, with their relative positions remaining unchanged.

[0054] It should be noted that the connecting part 211 is not limited to being rotatably connected to the housing assembly 10. For example, in some other embodiments, the connecting part 211 can also be slidably connected to the housing assembly 10. As long as the unlocking part 232 is subjected to external force and drives the mating part 231 to move, it can drive the connecting part 211 of the clamping arm 21 to move, thereby driving the pressing part 212 of the clamping arm 21 to move away from the liquid stop clamp 200 so that the liquid stop clamp 200 can be opened. The specific design can be determined according to the actual design needs.

[0055] The liquid-stop clamp control mechanism 100 proposed in this embodiment of the invention, by setting the control component 20 including a clamping arm 21, a first elastic member 22, and an unlocking arm 23, can control the closing and opening of the liquid-stop clamp 200 through the cooperation of the clamping arm 21, the first elastic member 22, and the unlocking arm 23. The structure is simple and can effectively reduce costs and improve reliability. In addition, by setting the pressing part 212 on the first side of the accommodating space 11 and the unlocking part 232 on the second side of the accommodating space 11, the thickness of the liquid-stop clamp control mechanism 100 can be effectively reduced, thereby reducing the space occupied by the liquid-stop clamp control mechanism 100 in the infusion pump 1000.

[0056] like Figures 2 to 7 As shown, in some embodiments, the infusion pump 1000 includes a main body 400 and a switch cover 500. A stop clamp control mechanism 100 is mounted on the main body 400 of the infusion pump 1000. The switch cover 500 is rotatably connected to the main body 400. The switch cover 500 has an open state and a closed state relative to the main body 400. During the process of rotating the switch cover 500 from the open state to the closed state, the switch cover 500 applies an external force to the unlocking part 232, causing the unlocking part 232 to drive the mating part 231 to move, thereby driving the connecting part 211 of the clamping arm 21 to move, and causing the pressing part 212 of the clamping arm 21 to move away from the stop clamp 200. For example, in one embodiment, the switch cover 500 is provided with a beveled part 510. During the process of rotating the switch cover 500 from the open state to the closed state, the beveled part 510 abuts against the unlocking part 232, thereby applying an external force to the unlocking part 232. In this embodiment, medical staff can apply external force to the unlocking part 232 while closing the switch cover 500, without having to take additional measures to apply external force to the unlocking part 232, thus improving the convenience of operation.

[0057] Of course, the way in which the unlocking part 232 is subjected to external force is not limited to the switch cover 500. For example, in some other embodiments, a driving component can be set separately. When it is necessary to open the liquid stop clamp 200, the driving component applies external force to the unlocking part 232. The specific method can be determined according to the actual design requirements.

[0058] like Figures 2 to 7 As shown, the following describes several implementation processes of controlling the flow path of liquid in the infusion tube 300 by the cooperation of the liquid stop clamp control mechanism 100, the liquid stop clamp 200 and the switch cover 500, taking the external force on the unlocking part 232 coming from the switch cover 500 as an example.

[0059] When medical staff insert the infusion tubing 300 and the stop clamp 200 into the infusion pump 1000, they first clamp the stop clamp 200 onto the infusion tubing 300, open the switch cover 500, and then insert the stop clamp 200 into the receiving space 11 through the mounting port 12 of the stop clamp control mechanism 100. During the insertion of the stop clamp 200 into the receiving space 11, the compression of the first elastic element 22 increases, and the clamping arm 21 applies pressure to the stop clamp 200 under the elastic force of the first elastic element 22, causing the stop clamp 200 to change from the open state to the closed state. At this time, the stop clamp 200 clamps the infusion tubing 300, thereby cutting off the flow path of the liquid in the infusion tubing 300, and the medicine or nutrient solution cannot be delivered to the patient through the infusion tubing 300. Of course, medical staff can also manually press the stop clamp 200 to change the stop clamp 200 from the open state to the closed state, and then insert the stop clamp 200 into the receiving space 11 from the installation port 12 of the stop clamp control mechanism 100. The stop clamp 200 is kept in the closed state under the pressure of the clamping arm 21.

[0060] After the stop clamp 200 is installed, medical staff close the switch cover 500. During the closing process, the switch cover 500 applies external force to the unlocking part 232 of the unlocking arm 23. The unlocking part 232 drives the mating part 231 to move, which in turn drives the connecting part 211 of the clamping arm 21 to move. The moving connecting part 211 drives the pressing part 212 of the clamping arm 21 to move away from the stop clamp 200. The pressing part 212 releases the pressure on the stop clamp 200, and the stop clamp 200 is in a state that can be opened. At the same time, the switch cover 500 is also in use. The protrusion 520 on the upper part presses the first latching part 240 of the stop clamp 200, causing the first latching part 240 and the second latching part 250 of the stop clamp 200 to separate. The first clamping arm 210 and the second clamping arm 220 of the stop clamp 200 spring open under the elastic force of the spring arm 230. At this time, the stop clamp 200 releases the part of the infusion tube 300 that is clamped, and the liquid flow path in the infusion tube 300 is opened. The medicine or nutrient solution can flow through the liquid flow path in the infusion tube 300 to the needle and be injected into the patient's body through the needle.

[0061] When medical staff open the switch cover 500 again, the external force applied by the switch cover 500 to the unlocking part 232 disappears, the clamping arm 21 loses the drive of the unlocking arm 23, and the clamping arm 21 moves back toward the stop clamp 200 under the elastic force of the first elastic element 22 and presses the stop clamp 200, so that the stop clamp 200 returns to the closed state. At this time, medical staff can remove the infusion tube 300 and the stop clamp 200 as a whole from the infusion pump 1000. Since the stop clamp 200 is in the closed state, there will be no accidental infusion to the patient after the infusion tube 300 is removed.

[0062] like Figure 5As shown, in some embodiments, the pressing portion 212 extends out of the housing assembly 10.

[0063] like Figure 5 and Figure 8 As shown, in some embodiments, a hook-shaped portion 213 is provided at the end of the pressing portion 212 away from the connecting portion 211. The hook-shaped portion 213 is used to abut against the liquid stop clamp 200 installed in the accommodating space 11 to restrict the liquid stop clamp 200 within the accommodating space 11.

[0064] In some embodiments, the connecting portion 211 and the pressing portion 212 are integrally formed. Of course, the connecting portion 211 and the pressing portion 212 are not limited to being integrally formed; for example, in some other embodiments, the connecting portion 211 and the pressing portion 212 are separately disposed and then assembled together by mechanical coupling, depending on the actual design requirements. In some embodiments, the connecting portion 211, the pressing portion 212, and the hook-shaped portion 213 are integrally formed.

[0065] like Figure 2 and Figure 9 As shown, in some embodiments, the control component 20 further includes a first rotating shaft 24, which is disposed at the end of the connecting portion 211 away from the pressing portion 212, and the first rotating shaft 24 is rotatably connected to the housing component 10.

[0066] like Figure 5 As shown, in some embodiments, the connecting portion 211 includes a U-shaped portion 2111 and an extension portion 2112. One end of the U-shaped portion 2111 is connected to the pressing portion 212, and the other end of the U-shaped portion 2111 is connected to the extension portion 2112. The first rotating shaft 24 is disposed at the end of the extension portion 2112 away from the U-shaped portion 2111. The U-shaped portion 2111 encloses the mounting space of the first elastic member 22. This embodiment is beneficial for making the liquid-stopping clamp control mechanism 100 compact. The extension portion 2112 is used to extend the lever arm. Understandably, the longer the lever arm, the less elastic force is required for the first elastic member 22 to drive the pressing portion 212 to press the liquid-stopping clamp 200. Of course, the connecting portion 211 is not limited to the above structure. The structure can be adjusted according to the actual specific design needs. For example, the U-shaped portion 2111 or the extension portion 2112 may not be provided.

[0067] like Figure 3 and Figure 5 As shown, in some embodiments, the housing assembly 10 is provided with a first stop portion 13, which is used to abut against the pressing portion 212. When the liquid-stopping clamp 200 is not installed in the receiving space 11, under the elastic force of the first elastic member 22, the pressing portion 212 abuts against the first stop portion 13, so that the clamping arm 21 is stable and does not wobble.

[0068] like Figure 5 As shown, in some embodiments, the unlocking part 232 extends out of the housing assembly 10.

[0069] like Figure 5 As shown, in some embodiments, the unlocking arm 23 further includes a hinge portion 233, which is located between the mating portion 231 and the unlocking portion 232, and is hinged to the housing assembly 10.

[0070] In some embodiments, the unlocking part 232 and the mating part 231 are integrally formed. Of course, the unlocking part 232 and the mating part 231 are not limited to being integrally formed; for example, in some other embodiments, the unlocking part 232 and the mating part 231 are separately disposed and then assembled together by mechanical coupling, depending on the actual design requirements. In some embodiments, the unlocking part 232, the mating part 231, and the hinge part 233 are integrally formed.

[0071] like Figure 5 and Figure 9 As shown, in some embodiments, the control component 20 further includes a second rotating shaft 25, which is disposed at the hinge portion 233 and is rotatably connected to the housing component 10.

[0072] like Figure 5 and Figure 9 As shown, in some embodiments, the control component 20 further includes a second elastic member 26, which is mounted on the housing assembly 10 and abuts against the side of the unlocking part 232 facing the clamping arm 21. In this embodiment, under the elastic force of the second elastic member 26, the pushing force of the connecting part 211, and the constraint of the second rotating shaft 25, the unlocking arm 23 is made stable and does not wobble.

[0073] like Figure 5 and Figure 9 As shown, in some embodiments, the control component 20 further includes a rolling element 27, which is rotatably mounted on the mating portion 231 and abuts against the connecting portion 211. In this embodiment, by providing the rolling element 27 to create rolling friction between the mating portion 231 and the connecting portion 211, the frictional force between them can be reduced, allowing for effective force transmission and smooth relative movement.

[0074] like Figure 5 , Figure 9 and Figure 10As shown, in some embodiments, the rolling element 27 is a roller, and the control component 20 also includes a third rotating shaft 28, which is connected to the roller. The mating part 231 is provided with an assembly groove 2311, and the third rotating shaft 28 is disposed in the assembly groove 2311 and rotatably connected to the mating part 231. The roller is partially located in the assembly groove 2311 and partially exposed outside the assembly groove 2311 and abuts against the connecting part 211.

[0075] It should be noted that the rolling element 27 is not limited to the above-described roller embodiment. For example, in some other embodiments, the rolling element 27 can be a ball, and the mating part 231 is provided with a groove on the side facing the connecting part 211. The rolling element 27 can be rolled into the groove and abut against the connecting part 211.

[0076] Of course, in some other embodiments, the control component 20 may not have a rolling element 27, and the mating part 231 and the connecting part 211 may be in direct contact. The specific design can be determined according to the actual design requirements.

[0077] like Figure 5 and Figure 8 As shown, in some embodiments, a wiring channel 14 is formed between the pressing part 212 and the unlocking part 232 in the thickness direction Z. When the infusion tube 300 is installed in the infusion pump 1000, the portion of the infusion tube 300 corresponding to the housing assembly 10 is laid along the wiring channel 14. The wiring channel 14 can serve to avoid, limit, and constrain the infusion tube 300.

[0078] In some embodiments, the wiring channel 14 is formed by a recess along the length direction Y on one side of the housing assembly 10 where the mounting port 12 is provided, and the wiring channel 14 intersects with the accommodating space 11.

[0079] Of course, in some other embodiments, the housing assembly 10 may not have a wiring channel 14 or may have a wiring channel 14, but it is also possible that the wiring channel 14 is not located on the side of the housing assembly 10 where the mounting port 12 is located. The specific arrangement can be determined according to the actual design requirements.

[0080] In some embodiments, the distance between the pressing part 212 and the unlocking part 232 in the width direction X is configured to be greater than the outer diameter of the infusion tube 300. Understandably, since the pressing part 212 and the unlocking part 232 are movable components, the distance between them in the width direction X varies depending on their positions. In this embodiment, "the distance between the pressing part 212 and the unlocking part 232 in the width direction X is configured to be greater than the outer diameter of the infusion tube 300" means that regardless of their positions, the distance between them in the width direction X is always greater than the outer diameter of the infusion tube 300. In this embodiment, it is possible to avoid the situation where the distance between the pressing part 212 and the unlocking part 232 is too small, causing interference between the pressing part 212 and / or the unlocking part 232 and the infusion tube 300 during installation, thus avoiding the need for additional operations to release the interference between the pressing part 212 and / or the unlocking part 232. Therefore, in this embodiment, by configuring the distance between the pressing part 212 and the unlocking part 232 in the width direction X to be greater than the outer diameter of the infusion tube 300, the installation operation of the infusion tube 300 can be simplified, which is beneficial to improving the user experience.

[0081] In some embodiments, when the unlocking part 232 is subjected to an external force, it moves and drives the connecting part 211 of the clamping arm 21 to move through the mating part 231, thereby causing the pressing part 212 of the clamping arm 21 to move away from the liquid-stopping clamp 200 so that the liquid-stopping clamp 200 can be opened. The component of the movement of the unlocking part 232 in the width direction X is opposite to the component of the movement of the pressing part 212 in the width direction X. Figure 5 As shown, when the unlocking part 232 is subjected to an external force, the component of the movement of the unlocking part 232 in the width direction X moves to the right, and the component of the movement of the pressing part 212 in the width direction X moves to the left.

[0082] The above description is based on the premise that the unlocking arm 23 and the clamping arm 21 are separate components. It should be noted that the unlocking arm 23 and the clamping arm 21 are not limited to being separate components. For example, in some other embodiments, the unlocking arm 23 and the clamping arm 21 can also be an integrated structure. The term "integrated structure" includes both two parts of a single molded component (unlocking arm 23 and clamping arm 21) and two independently configured parts assembled together by mechanical connection, with their relative positions remaining unchanged. In this embodiment, the control component 20 does not include a second elastic element 26 and a second rotating shaft 25.

[0083] It should be noted that when the unlocking arm 23 and the clamping arm 21 are configured as an integral structure, the unlocking part 232 moves under the action of external force and drives the connecting part 211 of the clamping arm 21 to move through the mating part 231, so as to drive the pressing part 212 of the clamping arm 21 to move away from the liquid-stopping clamp 200, so that the liquid-stopping clamp 200 can be opened. The component of the movement of the unlocking part 232 in the width direction X is the same as the component of the movement of the pressing part 212 in the width direction X. Figure 5 As shown, when the unlocking part 232 is subjected to an external force, the component of the movement of the unlocking part 232 in the width direction X moves to the left, and the component of the movement of the pressing part 212 in the width direction X also moves to the left.

[0084] like Figure 5 and Figure 9 As shown, in some embodiments, the control assembly 20 further includes a stop clamp in-place detection assembly 29. The stop clamp in-place detection assembly 29 includes a structural member 291, a magnet 292, and a reset member 293. The structural member 291 is movably mounted on the housing assembly 10 and partially extends into the receiving space 11. The magnet 292 is connected to the structural member 291. With the movement of the structural member 291, the magnet 292 has a first position and a second position relative to the Hall sensor 600 disposed within the infusion pump 1000. The magnet 292 is used to enable the Hall sensor 600 to detect changes in magnetic flux when switching between the first and second positions, thereby enabling the Hall sensor 600 to detect the position of the magnet 292. When the stop clamp 200 is installed in the receiving space 11, the stop clamp 200 abuts against the structural member 291, causing the magnet 292 to be in the second position. The reset member 293 is connected to the structural member 291 and provides a reset force so that when the stop clamp 200 is not installed in the receiving space 11, the magnet 292 returns to the first position. The reset element 293 can be, but is not limited to, a torsion spring. In this embodiment, compared to the existing method of using photoelectric sensors to detect the presence of the stop clamp 200, this embodiment uses a magnet 292 in conjunction with a Hall sensor 600 to detect the presence of the stop clamp 200. This eliminates the need for openings in the housing assembly 10, effectively preventing external medications and contaminants from entering the infusion pump 1000 through the mounting port 12 and accommodating space 11 of the housing assembly 10 and damaging the internal electronic components. Furthermore, the detection method using the Hall sensor 600 and magnet 292 is unaffected by dust, ensuring high reliability. Of course, the presence detection component of the stop clamp control mechanism 100 proposed in this application can also use a photoelectric sensor, depending on the actual design requirements.

[0085] like Figure 10As shown, in some embodiments, structural member 291 includes a pivot portion 2911, a first arm 2912, and a second arm 2913. The pivot portion 2911 is rotatably connected to the housing assembly 10. The first arm 2912 is connected to the pivot portion 2911 and partially extends into the receiving space 11. The second arm 2913 is connected to the pivot portion 2911, and a magnet 292 is connected to the second arm 2913.

[0086] In some embodiments, the housing assembly 10 is a closed structure except for the mounting port 12, such that when the housing assembly 10 is installed on the main body 400 of the infusion pump 1000, the internal space of the housing assembly 10 is not in communication with the internal space of the main body 400. In this embodiment, by ensuring that the internal space of the housing assembly 10 is not in communication with the internal space of the main body 400 of the infusion pump 1000, external medications and contaminants can be effectively prevented from entering the interior of the infusion pump 1000 through the mounting port 12 and the accommodating space 11 of the housing assembly 10, thus avoiding damage to the internal electronic components of the infusion pump 1000.

[0087] like Figures 1 to 11 As shown, an embodiment of the present invention also proposes a stop clamp control mechanism 100 for use in an infusion pump 1000 to control the closing and opening of the stop clamp 200. The proposed stop clamp control mechanism 100 includes a housing assembly 10 and a stop clamp in-situ detection assembly 29. The housing assembly 10 is provided with a receiving space 11 and a mounting port 12. The stop clamp 200 is inserted into the receiving space 11 through the mounting port 12. The stop clamp in-situ detection assembly 29 includes a structural member 291, a magnet 292, and a reset member 293. The structural member 291 is movably mounted on the housing assembly 10 and partially extends into the receiving space 11. Magnet 292 is connected to structural member 291. As structural member 291 moves, magnet 292 has a first position and a second position relative to Hall sensor 600 located within infusion pump 1000. Magnet 292 is used to enable Hall sensor 600 to detect changes in magnetic flux when switching between the first and second positions, thus allowing Hall sensor 600 to detect the position of magnet 292. When a stop clamp 200 is installed in the accommodating space 11, the stop clamp 200 abuts against structural member 291, placing magnet 292 in the second position. Reset member 293 is connected to structural member 291 and provides a reset force, causing magnet 292 to return to the first position when stop clamp 200 is not installed in the accommodating space 11.

[0088] The liquid stop clamp control mechanism 100 proposed in this embodiment of the invention, compared with the existing method of using photoelectric sensors to detect the liquid stop clamp 200 in place, uses a magnet 292 in conjunction with a Hall sensor 600 to detect the liquid stop clamp 200 in place. This eliminates the need to make openings in the housing assembly 10, effectively preventing external liquid medicine and dirt from entering the infusion pump 1000 through the mounting port 12 and the accommodating space 11 of the housing assembly 10 and damaging the electronic components inside the infusion pump 1000. Moreover, the detection method of Hall sensor 600 in conjunction with magnet 292 is not affected by dust and has high reliability.

[0089] In some embodiments, the housing assembly 10 is a closed structure except for the mounting port 12, such that when the housing assembly 10 is installed on the main body 400 of the infusion pump 1000, the internal space of the housing assembly 10 is not in communication with the internal space of the main body 400.

[0090] In some embodiments, structural member 291 includes a pivot portion 2911, a first arm 2912 and a second arm 2913. The pivot portion 2911 is rotatably connected to the housing assembly 10. The first arm 2912 is connected to the pivot portion 2911 and partially extends into the accommodating space 11. The second arm 2913 is connected to the pivot portion 2911. A magnet 292 is connected to the second arm 2913.

[0091] Other connection relationships, other component structures, extended descriptions, and beneficial effects of the anti-liquid clamp control mechanism 100 proposed in this embodiment can be referred to the above embodiment, and will not be repeated here.

[0092] See Figures 1 to 11In addition to the structure of the present invention, an embodiment of the present invention also proposes a liquid-stopping clamp control mechanism 100 for use in an infusion pump 1000 to control the closing and opening of the liquid-stopping clamp 200. The liquid-stopping clamp control mechanism 100 includes a housing assembly 10 and a control assembly 20. The liquid-stopping clamp control mechanism 100 is installed on the main body 400 of the infusion pump 1000 through the housing assembly 10. The housing assembly 10 is provided with a receiving space 11 and a mounting port 12. The liquid-stopping clamp 200 is inserted into the receiving space 11 through the mounting port 12. The receiving space 11 has a first side and a second side opposite to the first side in the width direction X. The direction in which the liquid-stopping clamp 200 is inserted into the receiving space 11 is the length direction Y of the receiving space 11. The arrangement direction of the two side walls of the receiving space 11 with the smaller distance is the thickness direction Z of the receiving space 11. The width direction X is perpendicular to the length direction Y and the thickness direction Z. The control assembly 20 includes a clamping arm 21, a first elastic member 22, and an unlocking arm 23. The clamping arm 21 includes a connecting portion 211 and a pressing portion 212. The connecting portion 211 is rotatably or slidably connected to the housing assembly 10. The pressing portion 212 is disposed on the first side of the accommodating space 11. The first elastic member 22 is mounted on the housing assembly 10 and abuts against the clamping arm 21 to provide elastic force so that the pressing portion 212 presses the anti-liquid clamp 200 located in the accommodating space 11, thereby keeping the anti-liquid clamp 200 closed. The unlocking arm 23 and the clamping arm 21 are an integral structure. The unlocking arm 23 includes a mating part 231 and an unlocking part 232. The unlocking part 232 is disposed on the first side of the accommodating space 11. When subjected to external force, the unlocking part 232 drives the mating part 231 to move, thereby driving the connecting part 211 of the clamping arm 21 to move the pressing part 212 of the clamping arm 21 away from the liquid stop clamp 200 so that the liquid stop clamp 200 can be opened.

[0093] The liquid-stopping clamp control mechanism 100 proposed in this embodiment of the invention, by setting the control component 20 including a clamping arm 21, a first elastic element 22, and an unlocking arm 23, can control the closing and opening of the liquid-stopping clamp 200 through the cooperation of the clamping arm 21, the first elastic element 22, and the unlocking arm 23. The structure is simple and can effectively reduce costs and improve reliability. In addition, by setting the unlocking arm 23 and the clamping arm 21 as an integral structure, and the pressing part 212 and the unlocking part 232 being located on the same side of the accommodating space 11, it is beneficial to reduce the assembly difficulty of the control component 20 and reduce the width of the liquid-stopping clamp control mechanism 100.

[0094] In some embodiments, the housing assembly 10 is provided with a wiring channel 14 extending along the thickness direction Z. When the infusion tube 300 is provided on the infusion pump 1000, the portion of the infusion tube 300 corresponding to the housing assembly 10 is laid along the wiring channel 14. The pressing part 212 and the unlocking part 232 are located on the same side of the wiring channel 14.

[0095] In some embodiments, the control assembly 20 further includes a stop clamp in-place detection assembly 29, which includes a structural member 291, a magnet 292, and a reset member 293. The structural member 291 is movably mounted on the housing assembly 10 and extends partially into the receiving space 11. The magnet 292 is connected to the structural member 291, and the magnet 292 has a first position and a second position relative to the Hall sensor 600 disposed in the infusion pump 1000 as the structural member 291 moves. The magnet 292 is used to enable the Hall sensor 600 to detect changes in magnetic flux when switching between the first and second positions, thereby enabling the Hall sensor 600 to detect the position of the magnet 292. When the stop clamp 200 is installed in the receiving space 11, the stop clamp 200 abuts against the structural member 291, so that the magnet 292 is in the second position. The reset member 293 is connected to the structural member 291, and the reset member 293 is used to provide a reset force so that when the stop clamp 200 is not installed in the receiving space 11, the magnet 292 is reset to the first position.

[0096] In some embodiments, structural member 291 includes a pivot portion 2911, a first arm 2912, and a second arm 2913. The pivot portion 2911 is rotatably connected to the housing assembly 10. The first arm 2912 is connected to the pivot portion 2911 and partially extends into the receiving space 11. The second arm 2913 is connected to the pivot portion 2911, and a magnet 292 is connected to the second arm 2913.

[0097] In some embodiments, the housing assembly 10 is a closed structure except for the mounting port 12, such that when the housing assembly 10 is installed on the main body 400 of the infusion pump 1000, the internal space of the housing assembly 10 is not in communication with the internal space of the main body 400.

[0098] Other connection relationships, other component structures, extended descriptions, and beneficial effects of the anti-liquid clamp control mechanism 100 proposed in this embodiment can be referred to the above embodiment, and will not be repeated here.

[0099] like Figures 1 to 11As shown, an embodiment of the present invention also proposes an infusion pump 1000, which includes a main body 400, a switch cover 500, and the aforementioned stop clamp control mechanism 100. The switch cover 500 is rotatably connected to the main body 400 and has an open state and a closed state relative to the main body 400. The switch cover 500 is provided with a beveled part 510 and a protrusion 520. The stop clamp control mechanism 100 is mounted on the main body 400. During the process of the switch cover 500 rotating from the open state to the closed state, the beveled part 510 abuts against and pushes the unlocking part 232. The unlocking part 232 drives the connecting part 211 of the clamping arm 21 to move, thereby causing the pressing part 212 of the clamping arm 21 to move away from the stop clamp 200. At the same time, the protrusion 520 presses the stop clamp 200, causing the two clamping arms 21 of the stop clamp 200 to spring open.

[0100] The infusion pump 1000 proposed in this embodiment, by adopting the aforementioned stop clamp control mechanism 100, has the advantages of simple structure, effective cost reduction and improved reliability, and reduced space occupation within the infusion pump 1000. Furthermore, by providing a beveled portion 510 and a protrusion 520 on the switch cover 500, during the rotation of the switch cover 500 from the open state to the closed state, the beveled portion 510 abuts against and pushes the unlocking portion 232. The unlocking portion 232 drives the connecting portion 211 of the clamping arm 21 to move, thereby causing the pressing portion 212 of the clamping arm 21 to move away from the stop clamp 200. Simultaneously, the protrusion 520 presses the stop clamp 200, causing the two clamping arms 21 of the stop clamp 200 to spring open. In this embodiment, medical personnel can open the stop clamp 200 while closing the switch cover 500, without additional operation, thus improving operational convenience.

[0101] In some embodiments, the infusion pump 1000 further includes a Hall sensor 600, which is mounted on the inner wall of the main body 400.

[0102] Other connection relationships, structures of other components, extended descriptions, and beneficial effects of the infusion pump 1000 proposed in this embodiment can be referred to the above embodiment, and will not be repeated here.

[0103] See Figures 1 to 11In addition to the above, embodiments of the present invention also provide an infusion pump 1000, which includes a main body 400, a switch cover 500, and a stop clamp control mechanism 100. The switch cover 500 is rotatably connected to the main body 400 and has an open state and a closed state relative to the main body 400. The switch cover 500 is provided with a beveled portion 510 and a protrusion 520. The stop clamp control mechanism 100 is mounted on the main body 400 and includes a housing assembly 10 and a control assembly 20. The housing assembly 10 is provided with a receiving space 11 and a mounting port 12. The stop clamp 200 is inserted into the receiving space 11 through the mounting port 12. The control assembly 20 includes a clamping arm 21 and a first elastic member 22. The clamping arm 21 includes a connecting portion 211 and a pressing portion 212. The connecting portion 211 is rotatably or slidably connected to the housing assembly 10. The first elastic member 22 is installed on the housing assembly 10 and abuts against the clamping arm 21 to provide elastic force so that the pressing portion 212 presses against the liquid-stopping clip 200 located in the accommodating space 11, thereby keeping the liquid-stopping clip 200 closed. During the process of the switch cover 500 rotating from the open state to the closed state, the inclined portion 510 abuts against and pushes the pressing portion 212, causing the pressing portion 212 to move away from the liquid-stopping clip 200. At the same time, the protrusion 520 presses against the liquid-stopping clip 200, causing the two clamping arms of the liquid-stopping clip 200 to spring open.

[0104] The infusion pump 1000 and the stop clamp control mechanism 100 proposed in this embodiment have a simple structure, which can effectively reduce costs and improve reliability. Moreover, medical staff can push the pressing part 212 while closing the switch cover 500, so that the pressing part 212 moves away from the stop clamp 200, without having to take additional measures to apply external force to the pressing part 212, thus improving the convenience of operation.

[0105] In some embodiments, the control assembly 20 further includes a stop clamp in-place detection assembly 29, which includes a structural member 291, a magnet 292, and a reset member 293. The structural member 291 is movably mounted on the housing assembly 10 and extends partially into the receiving space 11. The magnet 292 is connected to the structural member 291, and the magnet 292 has a first position and a second position relative to the Hall sensor 600 disposed in the infusion pump 1000 as the structural member 291 moves. The magnet 292 is used to enable the Hall sensor 600 to detect changes in magnetic flux when switching between the first and second positions, thereby enabling the Hall sensor 600 to detect the position of the magnet 292. When the stop clamp 200 is installed in the receiving space 11, the stop clamp 200 abuts against the structural member 291, so that the magnet 292 is in the second position. The reset member 293 is connected to the structural member 291, and the reset member 293 is used to provide a reset force so that when the stop clamp 200 is not installed in the receiving space 11, the magnet 292 is reset to the first position.

[0106] Other connection relationships, structures of other components, extended descriptions, and beneficial effects of the infusion pump 1000 proposed in this embodiment can be referred to the above embodiment, and will not be repeated here.

[0107] like Figures 1 to 11 As shown, an embodiment of the present invention also proposes an infusion pump 1000, which includes a main body 400, a stop clamp control mechanism 100, and a Hall sensor 600. The stop clamp control mechanism 100 is mounted on the main body 400 and is used to control the closing and opening of the stop clamp 200. The stop clamp control mechanism 100 includes a housing assembly 10 and a stop clamp in-situ detection assembly 29. The housing assembly 10 is provided with a receiving space 11 and a mounting port 12. The stop clamp 200 is inserted into the receiving space 11 through the mounting port 12. The stop clamp in-situ detection assembly 29 includes a structural member 291, a magnet 292, and a reset member 293. The structural member 291 is movably mounted on the housing assembly 10 and partially extends into the receiving space 11. Magnet 292 is connected to structural member 291. Magnet 292 has a first position and a second position relative to Hall sensor 600 as structural member 291 moves. Hall sensor 600 detects changes in magnetic flux at the first and second positions to determine the position of magnet 292. When liquid-stop clamp 200 is installed in accommodating space 11, liquid-stop clamp 200 abuts against structural member 291, causing magnet 292 to be in the second position. Reset member 293 is connected to structural member 291 and provides a reset force, causing magnet 292 to return to the first position when liquid-stop clamp 200 is not installed in accommodating space 11.

[0108] The infusion pump 1000 proposed in this embodiment, compared with the existing method of using photoelectric sensors to detect the presence of the stop clamp 200, uses a magnet 292 in conjunction with a Hall sensor 600 to detect the presence of the stop clamp 200. This eliminates the need to make openings in the housing assembly 10, effectively preventing external medications and dirt from entering the interior of the infusion pump 1000 through the mounting port 12 and the accommodating space 11 of the housing assembly 10 and damaging the internal electronic components of the infusion pump 1000. Moreover, the detection method of the Hall sensor 600 in conjunction with the magnet 292 is not affected by dust and has high reliability.

[0109] In some embodiments, the housing assembly 10 is a closed structure except for the mounting port 12, such that when the housing assembly 10 is installed on the main body 400 of the infusion pump 1000, the internal space of the housing assembly 10 is not in communication with the internal space of the main body 400.

[0110] In some embodiments, structural member 291 includes a pivot portion 2911, a first arm 2912 and a second arm 2913. The pivot portion 2911 is rotatably connected to the housing assembly 10. The first arm 2912 is connected to the pivot portion 2911 and partially extends into the accommodating space 11. The second arm 2913 is connected to the pivot portion 2911. A magnet 292 is connected to the second arm 2913.

[0111] Other connection relationships, structures of other components, extended descriptions, and beneficial effects of the infusion pump 1000 proposed in this embodiment can be referred to the above embodiment, and will not be repeated here.

[0112] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
