Description

Technical Field

[0001] This utility model belongs to the field of medical micro-infusion pump technology, and in particular relates to a residual dose measuring ruler for an intravenous injection pump. Background Technology

[0002] Micro-infusion devices primarily rely on pressure differentials and absolute fluid control, precisely regulating drug flow and rate through the movement of pistons or rollers. Specifically, the core components of a micro-infusion pump include a controller, an actuator, and a syringe. During operation, the microcomputer control system sends control pulse signals to activate a stepper motor. The lead screw, driven by the stepper motor, rotates, and a nut (push head) converts this rotational motion into linear motion, thereby pushing the syringe piston to inject the drug.

[0003] In addition, micro-infusion pumps have the function of real-time monitoring of drug pressure and flow rate, which can automatically adjust the injection speed to ensure accurate drug dosage and provide stable infusion effect. During use, the drug name is labeled on the syringe, or a light-proof syringe is used, making it impossible to see the markings on the syringe and monitor the remaining dosage in real time. Summary of the Invention

[0004] The purpose of this invention is to provide a residual dose measuring ruler for an intravenous injection pump. By fixing a residual dose measuring ruler for the injection solution to the housing of the injection pump, the problem of existing syringes being obstructed and unable to observe the residual dose in real time is solved.

[0006] This utility model relates to a residual dose measuring ruler for an intravenous infusion pump, comprising an infusion pump frame and a syringe clamping part located on the infusion pump frame. The syringe clamping part includes a syringe flange positioning member and a clamping handle movably connected to the pump body. A measuring ruler is fixed on the infusion pump frame, and the measuring ruler corresponds to the syringe. A pointer is engaged on the clamping handle, and the pointer corresponds to the scale of the measuring ruler.

[0007] Furthermore, the measuring ruler includes a square scale bar, a first knob pin, a rubber ring, and a fixing base; the fixing base is a U-shaped plate structure, and a first support plate and a second support plate with through holes are respectively provided at both ends of the fixing base; a first stud is provided at one end of the square scale bar, and a screw hole is provided at the other end of the square scale bar; the first stud at one end of the square scale bar passes through a rubber ring and a second support plate in sequence and is connected by bolts; a nut, a rubber ring, a first support plate, a rubber ring, a nut, and a screw hole at one end of the square scale bar are sequentially fitted on the first knob pin.

[0008] Furthermore, an adhesive layer is fixed to the bottom surface of the mounting base, and the measuring ruler is fixed above the syringe of the injection pump frame through the adhesive layer.

[0009] Furthermore, the adhesive layer is medical double-sided tape.

[0010] Furthermore, the square dimension strip is a quadrangular prism structure.

[0011] Furthermore, the four sides of the square scale bar are respectively provided with graduations, which correspond to the graduation values ​​of syringes with specifications of 50ml, 30ml, 20ml and 10ml.

[0012] Furthermore, the pointer includes a crossbar, a clamping part, and a needle. The clamping part is located at one end of the crossbar, and the needle is located at the other end of the crossbar. The clamping part is clamped on the clamp handle. The needle corresponds to the scale value on the square scale bar.

[0013] Furthermore, the clamping part is a U-shaped clamp structure, with a through threaded hole on one side of the U-shaped clamp structure, and a second knob screw fitted on the through threaded hole; the clamping part is fixed to the clamp handle by the second knob screw, and the pointer moves with the movement of the clamp handle.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] like Figure 1-3 As shown, this embodiment is a residual dose measuring ruler for an intravenous infusion pump, including an infusion pump frame 1 and a syringe clamping part located on the infusion pump frame 1. The syringe clamping part includes a syringe flange positioning member and a clamping handle 101 movably connected to the pump body. A measuring ruler 2 is fixed on the infusion pump frame 1, and the measuring ruler 2 corresponds to the syringe. A pointer 3 is snapped onto the clamping handle 101, and the pointer 3 corresponds to the scale of the measuring ruler 2.

[0031] Therefore, when the name of the drug is labeled on the syringe during use, or when the remaining dose cannot be observed in real time with a light-proof syringe, the remaining dose of the drug in the syringe is indicated by the value on the measuring ruler 2 corresponding to the scale value on the syringe. As the pointer 3 on the clamp 101 moves with the clamp 101, the value on the measuring ruler 2 indicated by the pointer 3 is the remaining dose of the drug in the syringe.

[0032] like Figure 4 As shown, the measuring ruler 2 includes a square scale bar 201, a first knob pin 204, a rubber ring 205, and a fixing base 202; the square scale bar 201 is a quadrangular prism structure, and scales are set on the four peripheral sides of the square scale bar 201, which correspond to the scale values ​​of syringes with specifications of 50ml, 30ml, 20ml, and 10ml respectively.

[0033] The first knob pin 204 is sequentially fitted with a nut, a rubber ring 205, a first support plate 221, and a screw hole 211 at one end of the square dimension strip 201. The first knob pin 204 is fixed to the end of the square dimension strip 201 by one nut, and the rubber ring 205 is attached to the first support plate 221 by another nut, creating a pre-tightening force on the rubber ring 205. This allows the square dimension strip 201 to remain in the same position due to friction. When changing to a different size syringe, the first knob pin 204 is rotated so that the scale value of the corresponding syringe size on one surface of the square dimension strip 201 faces outwards.

[0034] like Figure 6 As shown, the fixing base 202 has a U-shaped plate structure, and a first support plate 221 with through holes and a second support plate 222 are respectively provided at both ends of the fixing base 202. Figure 7 As shown, an adhesive layer 203 is fixed to the bottom surface of the fixing base 202, and the measuring ruler 2 is fixed above the syringe of the injection pump frame 1 through the adhesive layer 203. The adhesive layer 203 is medical double-sided tape.

[0035] like Figure 5 As shown, a first stud 212 is provided at one end of the square dimension strip 201, and a screw hole 211 is provided at the other end of the square dimension strip 201; the first stud 212 at one end of the square dimension strip 201 passes through a rubber ring 205 and a second support plate 222 in sequence and is connected by bolts. The function of the rubber ring 205 is to provide elastic friction so that the square dimension strip 201 can be rotated under the action of torque in order to maintain its stability when no force is applied.

[0036] like Figure 8As shown, the pointer 3 includes a crossbar 302, a clamping part 301, and a needle 303. The clamping part 301 is located at one end of the crossbar 302, and the needle 303 is located at the other end of the crossbar 302. The clamping part 301 is clamped on the handle 101. The needle 303 corresponds to the scale value on the square scale bar 201.

[0037] like Figure 9 As shown, the clamping part 301 is a U-shaped clamp structure. A through-hole is provided on one side of the U-shaped clamp structure, and a second knob pin 304 is fitted on the through-hole. The clamping part 301 is fixed to the clamp handle 101 by the second knob pin 304. As the clamp handle 101 moves, the pointer 3 moves accordingly.

[0038] The crossbar 302 is a telescopic rod structure, which ensures that the needle 303 corresponds to the initial position of the syringe when it is in its initial position.
