Abstract
Description
Technical Field
[0001] This invention belongs to the field of infusion pump technology, specifically an infusion pump stabilization assembly mechanism. Background Technology
[0002] Currently, PIN switches are the most commonly used high-power switches. Their advantages include the ability to control higher RF power with a smaller DC power, unlimited lifespan regardless of the number of switching cycles, and fast switching speed. Therefore, selecting a suitable PIN diode and its driver circuit is crucial. High-power PIN diode switches typically use TTL signal control, and since the PIN diode is a charge-controlled device, a driver circuit is needed to act as a buffer. The driver circuit is generally designed using a combination of resistors and PMOS field-effect transistors or bipolar transistors.
[0003] This approach typically has the following drawbacks: This traditional drive circuit requires a large number of discrete components, which takes up a lot of printed circuit board space. At the same time, it is impossible to control the turn-on timing of the two PMOS field-effect transistors / transistors, which can easily cause one PMOS field-effect transistor / transistor to be turned on while the other PMOS field-effect transistor / transistor is not yet turned off, resulting in unreliable circuits.

[0020] Example 1 Reference Figures 1-6 This embodiment provides a stable assembly mechanism for an infusion pump, including a base 100, on which a first base 200, a second base 300, and a movable block 400 are provided. A guide rod 101 and a lead screw 102 are provided between the first base 200 and the second base 300. The movable block 400 is provided with a threaded hole and a through hole. The guide rod 101 is provided through the through hole, and the lead screw 102 is engaged with the threaded hole. The second base 300 is provided with a vertical groove 301, the bottom of the vertical groove 301 is provided with a fixing groove 302, and the two sides of the vertical groove 301 are provided with locking blocks 500. The syringe 600 is disposed in the fixing groove 302.
[0021] One end of the lead screw 102 is connected to a rotary motor. By controlling the rotation of the rotary motor, the moving block 400 moves along the guide rod 101.
[0022] The fixing groove 302 is a semi-circular structure that fits the shape of the syringe.
[0023] The base 100 integrates a control device, which is existing technology, used to control the action of the push rod by setting parameters.
[0024] The side wall of the vertical groove 301 is provided with a side groove 301a, and the side groove 301a is provided with a limiting groove 301b on both sides.
[0025] The locking block 500 is embedded in the side groove 301a. Side plates 501 are provided on both sides of the locking block 500. The side plates 501 are embedded in the limiting groove 301b. A spring 301c is provided in the side groove 301a to connect the locking block 500.
[0026] A first arc groove 502 is provided above one end of the card block 500, and a second arc groove 503 is provided below the card block 500.
[0027] Both sides of the vertical groove 301 are provided with locking blocks, and the locking blocks on both sides are set accordingly. The second arc groove 503 of the two locking blocks and the fixing groove 302 are combined to form a circular structure to fix the syringe in the fixing groove 302.
[0028] A pressure rod 303 is provided on the second base 300. The pressure rod 303 is hinged to the edge of the vertical groove 301 and is located in the first arc groove 502.
[0029] A handle 303a is provided on the top of the pressure rod 303.
[0030] A first clamping plate 401 is provided on one side of the movable block 400. The first clamping plate 401 is fixed to one side of the movable block 400 by bolts. A first slot 402 is provided between the first clamping plate 401 and the movable block 400.
[0031] The first slot is used to hold the rod head of the syringe piston rod.
[0032] A second clamping plate 304 is fixed to one side of the second base 300 by bolts, and a second slot 305 is provided between the second clamping plate 304 and the second base 300.
[0033] The second slot 305 is used to fix the end of the syringe body.
[0034] In this embodiment, during the assembly of the syringe, the side lug at the end of the syringe is aligned with the second side groove, and the end of the syringe piston rod is aligned with the first side groove. Then, the syringe is placed into the vertical groove. After placement, in its natural state, the syringe is located at the first arc groove. When the syringe is pressed downward, the locking block 500 is pushed back to both sides. The locking block 500 compresses the spring, and the locking block retracts into the side groove. The syringe moves into the fixing groove. Then, the locking block 500 returns to its original position under the action of the spring. The locking block is positioned above the syringe to fix the syringe.
[0035] Then rotate the pressure rod to place it in the first arc groove, so that there is no space above the blocking block, and the syringe cannot move upwards for several pages and cannot push the blocking block open.
[0036] Furthermore, a magnetic layer can be provided on the contact surface between the first arc groove and the pressure rod 303, so that the first arc groove and the pressure rod 303 attract each other, further restricting the movement of the locking block 500.
[0037] To remove it, lift the pressure lever 303 away from the vertical groove, and then lift the syringe upwards.
[0038] In this structure, the spring force can be small, making it easy to pick up and put down the syringe, but the fixing effect is still very good.
[0039] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
