Technical Field

[0001] The utility model relates to the technical field of infusion controllers, in particular to a motor fixing plate for an infusion controller. Background Technique

[0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolyte, and drug into the body by using the principles of atmospheric pressure and hydrostatic pressure. Injecting a large amount of liquid, electrolyte, or blood into a vein is called intravenous infusion. Depending on the injection site and the type of infusion, it can be divided into peripheral intravenous infusion, central venous infusion, hyperalimentation infusion, and blood transfusion, etc.

[0003] With the development of technology, when performing infusion, an infusion controller is used to automatically control the liquid medicine flow rate. When installing the motor in the infusion controller, a fixing plate is required to fix it inside the infusion controller. However, the existing motor fixing plate structure has certain defects. When the clamping plate clamps the infusion tube, the infusion tube is prone to lateral displacement and slips off from one side of the clamping plate. For this reason, we propose a motor fixing plate for an infusion controller. Content of the Utility Model

[0004] The purpose of the utility model is to provide a motor fixing plate for an infusion controller to solve the problems raised in the above background technique.

[0027] As Figures 1-4 shown, a technical solution provided by the present utility model is as follows:

[0028] An infusion controller motor fixing plate, comprising a fixing frame 1, a motor 2 is arranged on one side of the fixing frame 1, a fixing sleeve 3 is arranged on the side of the fixing frame 1 away from the motor 2, a shaft groove 4 is penetrated and opened in the middle of the fixing sleeve 3, the output shaft of the motor 2 passes through the shaft groove 4 and is fixedly connected with a screw rod 5, a movable sleeve 6 is threadedly connected to the outside of the screw rod 5, a guiding groove 7 is opened on one side of the fixing sleeve 3, a clamping head 8 is fixedly connected to the side of the movable sleeve 6 close to the guiding groove 7, the clamping head 8 is slidably connected with the guiding groove 7, the outside of the movable sleeve 6 is movably connected with the inside of the fixing sleeve 3, the motor 2 is installed on one side of the fixing frame 1, and the fixing frame 1 is used for being fixed inside the infusion set housing. When it is necessary to adjust the infusion volume, the motor 2 is started. After the motor 2 is started, it drives the screw rod 5 to rotate. After the screw rod 5 rotates, it drives the movable sleeve 6 to reciprocate back and forth inside the fixing sleeve 3. When the movable sleeve 6 moves, it drives the clamping head 8 on one side to linearly move synchronously in the guiding groove 7. When the clamping head 8 moves forward, the infusion tube clamped between the fixing frame 1 and the clamping head 8 is loosened. When the clamping head 8 moves backward, the infusion tube between the fixing frame 1 and the clamping head 8 is clamped, so as to achieve the purpose of being convenient for adjustment;

[0029] As Figure 1 shown, a slot 9 is penetrated and opened on the side of the fixing frame 1 close to the fixing sleeve 3, an installation groove 10 is opened at the bottom end of the fixing frame 1 close to the slot 9, a fixing block 11 is arranged inside the installation groove 10, a guiding block 12 is movably installed on the side of the fixing block 11 close to the slot 9, and the end of the guiding block 12 passes through the slot 9 and is movably connected to one side of the clamping head 8. The side of the fixing frame 1 close to the slot 9 extends outward. Since the infusion tube is prone to lateral displacement during clamping, a slot 9 is opened on one side of the fixing frame 1 in the present device, and the guiding block 12 is movably installed inside the slot 9. The infusion tube is placed at the position between the guiding block 12 and the fixing sleeve 3. When the clamping head 8 clamps the infusion tube, the moving range of the infusion tube is restricted by the guiding block 12 and the fixing sleeve 3, so that it will not fall off from the outside of the clamping head 8. In this way, the safety is higher during use;

[0030] As Figure 2 shown, inner rib strips 13 are fixedly connected to the four corners of the inner side of the fixing sleeve 3, and the four inner rib strips 13 are slidably connected to the outer wall of the movable sleeve 6. Inner rib strips 13 are arranged at the four corners inside the fixing sleeve 3. When the movable sleeve 6 slides, since the contact area with the outer wall of the movable sleeve 6 is reduced, the friction can be reduced, so that the sliding is smoother;

[0031] As Figure 2 shown, a plurality of first bolt columns 14 are arranged on the outside of the fixing sleeve 3, and outer rib strips 15 are arranged between the outside of the plurality of first bolt columns 14 and the fixing frame 1. The ends of the plurality of first bolt columns 14 are horizontal with the fixing sleeve 3. The outer rib strips 15 are arranged between the first bolt columns 14 and the fixing frame 1, which can improve the structural strength of the first bolt columns 14;

[0032] As Figure 3As shown, the fixing frame 1 is provided with second bolts 16 at both ends of the mounting groove 10, and the two second bolts 16 are fixedly connected to the two ends of the fixing block 11 by screws. The second bolts 16 are used to be threadedly connected with the screws to fix the fixing block 11 inside the mounting groove 10;

[0033] like Figure 1 As shown, a compression spring 17 is provided between the fixing block 11 and the middle part of the guide block 12. When the infusion set needs to be removed, the guide block 12 is pressed, and the guide block 12 is retracted into the slot 9, so that the infusion tube can be pushed to one side;

[0034] When the motor fixing plate of an infusion controller of the present embodiment is in use, the motor 2 is mounted on one side of the fixing frame 1, and the fixing frame 1 is used to be fixed inside the infusion device housing. When the infusion volume needs to be adjusted, the motor 2 is started. After the motor 2 is started, it drives the screw 5 to rotate. After the screw 5 rotates, it drives the movable sleeve 6 to move back and forth inside the fixed sleeve 3. When the movable sleeve 6 moves, it drives the chuck 8 on one side to move synchronously and linearly in the guide groove 7. When the chuck 8 moves forward, the infusion tube clamped between the fixing frame 1 and the chuck 8 is released. When the chuck 8 retreats, the infusion tube between the fixing frame 1 and the chuck 8 is clamped. Since the infusion tube is easily displaced laterally during clamping, a slot 9 is provided on one side of the fixing frame 1 of the present device. A guide block 12 is movably installed inside the slot 9 to place the infusion tube between the guide block 12 and the fixed sleeve 3. When the chuck 8 clamps the infusion tube, the moving range of the infusion tube is limited by the guide block 12 and the fixed sleeve 3, so that it will not fall off from the outside of the chuck 8. In this way, it is safer when in use.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
