Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a fluid exchange mechanism. Background Technology
[0002] Intravenous infusion is one of the commonly used treatment methods.
[0003] During intravenous infusion, nurses need to manually change the IV fluids. When there are many patients, especially when multiple patients are receiving IV infusions at the same time, the workload of nurses increases exponentially. Because there are many patients who need their IV fluids changed, nurses can only handle the situation based on the patients' calls. However, some patients may not call the nurse in time when they need their IV fluids changed due to negligence, and the nurse may be busy with the care of other patients, resulting in the inability to change the IV fluids of some patients in a timely manner.
[0004] Currently, there is a lack of facilities that can assist nurses in changing IV fluids.
[0005] Chinese patent CN106955393A discloses an automatic fluid replacement control method and device, and an automatic infusion robot. This patent discloses an automatic infusion robot. However, the device requires a robotic arm to grab and transfer the infusion bottle from the platform. The clamping part switches between clamping and releasing the infusion bottle, and the parallel pneumatic gripper performs the needle insertion action. The device requires the transfer of the infusion bottle, which is a relatively cumbersome action and may easily lead to the infusion bottle not moving into place, causing the parallel pneumatic gripper to fail to perform the needle insertion action smoothly.
[0006] Currently, there is a lack of a simple fluid exchange mechanism that does not require the transfer of infusion bottles. Utility Model Content
[0007] In view of the problems existing in the prior art, this utility model provides an infusion container fluid changing mechanism to solve at least one of the above technical problems.
[0008] To achieve the above objectives, this utility model provides an infusion container replacement mechanism, characterized in that it includes an infusion container fixing assembly, the infusion container fixing assembly including a fixing frame, and at least two infusion container clamping and fixing mechanisms arranged horizontally from left to right are installed on the fixing frame.
[0009] It also includes a fluid changing assembly, which includes a support frame and a three-dimensional linear motion mechanism that can move along three linear directions: left and right, front and back, and up and down. The movable end of the three-dimensional linear motion mechanism is equipped with a gripper for holding the needle, and the gripper includes two gripping parts arranged on the left and right.
[0010] The infusion container fixing assembly and the fluid replacement assembly are arranged in front of and behind each other.
[0011] This invention pre-fixes the infusion container with the infusion container fixing component. Then, the fluid changing component can switch the grippers to face different infusion containers to insert or remove the needle simply by moving the gripper in the left-right direction.
[0012] More preferably, the three-dimensional linear motion mechanism includes a first linear slide mechanism that slides in the left-right direction, a lifting slide mechanism that moves up and down in the vertical direction is mounted on the sliding platform of the first linear slide mechanism, a second linear slide mechanism that slides in the front-back direction is mounted on the sliding platform of the lifting slide mechanism, and the gripper is mounted on the sliding platform of the second linear slide mechanism.
[0013] When an IV drip needs to be changed, the lifting slide mechanism rises behind the needle, the grippers open, the second linear slide mechanism moves forward, the grippers close to clamp the needle, the lifting slide mechanism descends, and the first linear slide mechanism moves left and right to directly below the second IV container. The lifting slide mechanism rises, and the grippers, carrying the needle, insert into the second IV container, completing the IV drip change. After the second IV container has finished infusion, the lifting slide mechanism moves the grippers downwards to remove the needle, and the first linear slide mechanism moves left and right to directly below the third IV container. The lifting slide mechanism rises, and the grippers, carrying the needle, insert into the third IV container, completing the IV drip change.
[0014] In a further preferred embodiment, the clamping and fixing mechanisms of adjacent infusion containers are arranged at equal intervals from left to right.
[0015] This facilitates matching the movement distance of the first linear slide mechanism with the spacing of the infusion containers.
[0016] More preferably, the infusion container is an infusion bottle, and the infusion container clamping and fixing mechanism is a tube clamp used to clamp the body of the infusion bottle.
[0017] Alternatively, the infusion container is an infusion bag, and the infusion container clamping and fixing mechanism includes a hook for hanging the top of the infusion bag and a tube clamp for clamping the bag opening of the infusion bag.
[0018] The fixing frame is fixed with pipe clamps arranged at equal intervals from left to right, and the fixing frame is connected with hooks;
[0019] The hooks correspond one-to-one with the pipe clamps and are positioned vertically.
[0020] More preferably, the fixing frame is connected to the hook via a telescopic rod.
[0021] This makes it easy to ensure that the openings of infusion bags with different vertical heights are at the same height.
[0022] Alternatively, a pull rope is installed on the fixing frame, and the hook is installed on the pull rope.
[0023] The hook height can be adjusted by adjusting the length of the pull rope.
[0024] More preferably, the gripper is a pneumatic gripper or an electric gripper.
[0025] More preferably, the fixing frame and the support frame are provided with a matching connection structure.
[0026] It facilitates the relative fixation of the fixed frame and the support frame.
[0027] More preferably, the connecting structure includes a connecting rod, one end of which is detachably connected to the support frame, and the other end of which is detachably connected to the fixing frame.
[0028] More preferably, the fluid exchange assembly further includes a guide rail with a length direction of left and right and a traveling base that travels along the guide rail, with the support frame mounted on the traveling base.
[0029] This facilitates changing IV fluids for different patients. The IV containers required for the same patient are secured to the same IV container mounting assembly.
[0030] More preferably, the guide rail includes two guide rails arranged side by side, with a rack installed between the two guide rails;
[0031] The walking base includes a base plate, on which a slider that is slidably connected to the guide rail is mounted, and a motor is mounted on the base plate. A gear that meshes with the rack is mounted on the power output shaft of the motor.
[0032] It facilitates the movement of the fluid exchange assembly along the guide rail by the rotation of the motor.

[0048] The present invention will be further described below with reference to the accompanying drawings.
[0049] See Figures 1 to 8Specific Embodiment 1: An infusion container changing mechanism includes an infusion container fixing component, which includes a fixing frame with at least two horizontally arranged infusion container clamping and fixing mechanisms from left to right mounted on the fixing frame; it also includes a changing component 2, which includes a support frame with a three-dimensional linear motion mechanism that can move in three linear directions: left-right, front-back, and up-down. The movable end of the three-dimensional linear motion mechanism is equipped with a gripper 24 for holding a needle, and the gripper 24 includes two gripping parts arranged left and right. The infusion container fixing component and the changing component 2 are arranged front and back. This invention, by pre-fixing the infusion container with the infusion container fixing component, only requires the changing component 2 to move in the left-right direction to switch the gripper 24 to face different infusion containers for needle insertion and removal. The changing component can be located behind the patient.
[0050] The three-dimensional linear motion mechanism includes a first linear slide mechanism 21 that slides in the left-right direction, a lifting slide mechanism 22 that moves up and down in the vertical direction is mounted on the sliding platform of the first linear slide mechanism 21, a second linear slide mechanism 23 that slides in the front-back direction is mounted on the sliding platform of the lifting slide mechanism 22, and a gripper 24 is mounted on the sliding platform of the second linear slide mechanism 23.
[0051] When an infusion needs to be changed, the lifting slide mechanism 22 rises behind the needle, the gripper 24 is in the open state, the second linear slide mechanism 23 moves forward, the gripper 24 closes to clamp the needle, the lifting slide mechanism 22 descends, the first linear slide mechanism 21 moves left and right to directly below the second infusion container, the lifting slide mechanism 22 rises, and the gripper 24, carrying the needle, inserts into the second infusion container, completing the infusion change. After the infusion in the second infusion container is completed, the lifting slide mechanism 22 drives the gripper 24 to hold the needle and move downwards, the first linear slide mechanism 21 moves left and right to directly below the third infusion container, the lifting slide mechanism 22 rises, and the gripper 24, carrying the needle, inserts into the third infusion container, completing the infusion change.
[0052] The clamping and fixing mechanisms for adjacent infusion containers are arranged at equal intervals from left to right. This facilitates matching the movement distance of the first linear slide mechanism 21 with the spacing of the infusion containers.
[0053] The infusion container is an infusion bottle, and the infusion container clamping and fixing mechanism is a tube clamp used to clamp the body of the infusion bottle. A silicone pad is fixed to the inner wall of the tube clamp. Alternatively, the infusion container is an infusion bag 4, and the infusion container clamping and fixing mechanism includes a hook 12 for hanging the top of the infusion bag 4 and a tube clamp for clamping the bag opening. The bag opening of the infusion bag is a rigid connector for easy clamping and fixing. A silicone pad is fixed to the inner wall of the tube clamp. The tube clamp includes two semi-circular clamping bodies arranged front and back, which are detachably connected by bolts. Tube clamps are fixed on a fixing frame at equal intervals from left to right, and hooks 12 are installed on the fixing frame to connect them; the hooks 12 correspond one-to-one with the tube clamps and are arranged vertically. The fixing frame is connected to the hooks 12 via a telescopic rod 13. This facilitates ensuring that the bag openings of infusion bags with different vertical heights are at the same height. Alternatively, a pull rope 14 is installed on the fixing frame, and hooks 12 are installed on the pull rope 14. The height of the hook 12 can be adjusted by adjusting the length of the pull rope 14.
[0054] See Figure 2 In specific embodiment 2, based on specific embodiment 1, the fixed frame and the support frame are provided with a matching connection structure. This facilitates the relative fixation of the fixed frame and the support frame. The connection structure includes a connecting rod 3, one end of which is detachably connected to the support frame, and the other end of which is detachably connected to the fixed frame.
[0055] See Figure 1 In specific embodiment 3, based on specific embodiment 1, the fluid changing assembly further includes a guide rail extending horizontally along its length and a traveling base that moves along the guide rail. A support frame is mounted on the traveling base. This facilitates fluid changing for different patients. The infusion container required by the same patient is fixed on the same infusion container fixing assembly. The guide rail includes two parallel guide rails 25, with a rack 26 installed between the two guide rails 25. The traveling base includes a base plate 27, on which a slider that slides and connects to the guide rails is mounted. A motor is mounted on the base plate 27, and a gear that meshes with the rack 26 is mounted on the motor's power output shaft. This facilitates the movement of the fluid changing assembly along the guide rail by the rotation of the motor. When the traveling base moves to the corresponding infusion container fixing assembly position, the needle 5 is inserted or removed for the current patient.
[0056] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
