Description

Technical Field

[0001] The utility model relates to the technical field of infusion pumps, in particular to an upper and lower mutually superimposed locking mechanism for an infusion pump. Background Art

[0002] Based on the usage requirements of hospital departments, in most cases, several infusion pumps need to work simultaneously. At the same time, in order to facilitate medical staff to move the infusion pumps and grasp the operation status of the infusion pumps in real time, the infusion pumps need to be transmitted to the monitoring system through the workstation. In this context, the infusion pumps need to be stacked up and down to facilitate connection with the workstation.

[0003] In the prior art, such as the infusion pump stacking structure with publication number CN205235067U, an infusion pump is used to transport the medicine from the liquid storage device end to the patient end. The infusion pump includes a main body, a peristaltic component and a liquid stop clamp, and a controller; the peristaltic component is arranged at one end of the main body close to the liquid storage device, and is driven by a first motor to squeeze the medicine in the infusion tube toward the patient or the liquid storage device; the liquid stop clamp is arranged at one end of the main body close to the patient, and is driven by a second motor to clamp or release the infusion tube; the controller is electrically connected to the first motor and the second motor to control the operation of the first motor and the second motor. It arranges a liquid-stop clamp on the main body near the patient end, and controls the first motor to drive the peristaltic component to squeeze the liquid in the infusion tube and move it toward the liquid storage device, so as to draw the liquid in the infusion tube collected between the liquid-stop clamp and the peristaltic component back to the liquid storage device, thereby avoiding the generation of instantaneous bolus doses and ensuring the comfort of the patients. However, when multiple infusion pumps need to be stacked and used, they can only rely on the contact and fixation of the fitting surface, so that the infusion pump on the upper layer lacks horizontal limit, which makes the pump body easy to tip over and fall, and there are certain defects in use. Utility Model Content

[0004] The utility model aims to provide an upper and lower overlapping locking mechanism for infusion pumps, so as to solve the problem of poor stacking stability of infusion pumps in the current market when used in combination, as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an infusion pump has a locking mechanism superimposed on each other, comprising a first pump body and a second pump body superimposed on each other, wherein the first pump body and the second pump body are fixedly assembled by an upper shell and a lower shell, guide grooves are symmetrically provided on both sides of the upper shell, and connecting blocks are symmetrically provided below the lower shell, and a locking mechanism is installed on the lower shell, and at the same time, the locking mechanism on the first pump body is engaged and locked with the upper shell of the second pump body, and the locking mechanism comprises a locking plate rotatably installed on the lower shell, and a blocking block is fixedly provided on the outer side of the lower end of the locking plate.

[0006] Preferably, the cross-section of the connecting block is arranged in an L-shaped structure, the connecting block and the guide groove are slidably connected, and the lower shell and the connecting block are arranged in an integrated structure.

[0007] By adopting the above technical solution, when the first pump body and the second pump body are stacked and combined, the connecting block at the lower end of the first pump body can slide along the guide groove, thereby improving the stacking stability of the first pump body and the second pump body.

[0008] Preferably, a positioning surface is provided on the right side wall of the guide slot, and a positioning surface is also provided on the right end of the connecting block, and the positioning surfaces on both the guide slot and the connecting block are inclined, and the positioning surfaces on both the guide slot and the connecting block fit together.

[0009] By adopting the above technical solution, when the connecting block slides along the guide groove, the positioning surfaces above the two can play a positioning effect, ensuring the superposition flatness of the first pump body and the second pump body.

[0010] Preferably, the locking plate is rotatably connected to the lower shell via a rotating shaft, and a torsion spring is connected between the rotating shaft and the locking plate.

[0011] By adopting the above technical solution, pressing the upper end of the locking plate can make the locking plate rotate elastically around the rotating shaft, thereby locking and unlocking the first pump body and the second pump body, and improving the convenience of stacking and disassembling the first pump body and the second pump body.

[0012] Preferably, a card block is integrally provided at the lower end of the locking plate, and the card block passes through the connecting block, and the card block is perpendicular to the locking plate, and a positioning groove is provided on the inner wall of the guide groove, and the positioning groove and the card block are engaged with each other.

[0013] By adopting the above technical solution, after the clamping block is clamped into the positioning groove, the connecting block inside the guide groove can be limited, thereby ensuring the stacking stability of the first pump body and the second pump body.

[0014] Preferably, the clamping block is arranged in a right-angled trapezoidal structure, and one side of the clamping block facing the positioning surface of the connecting block is arranged as an inclined surface.

[0015] By adopting the above technical solution, when the first pump body and the second pump body are superimposed, when the connecting block slides along the guide groove, the inclined surface of the card block can be resisted by the inner wall of the guide groove to drive the locking plate to rotate automatically, without the user pressing the locking plate, thereby improving the convenience of sliding superposition.

[0016] Compared with the prior art, the beneficial effect of the utility model is that the upper and lower overlapping locking mechanisms of the infusion pump can be conveniently locked when the infusion pumps are stacked and combined, which effectively improves the stacking stability of the infusion pumps. The specific contents are as follows:

[0017] 1. A guide groove and a connecting block are provided. By sliding the first pump body against the surface of the second pump body, the connecting block on the first pump body will slide along the guide groove of the second pump body, thereby realizing the superposition of the first pump body and the second pump body, and improving the convenience of combined use of multiple sets of infusion pumps;

[0018] 2. A locking plate and a card block are provided. When the connecting block slides along the guide groove, the card block is resisted when contacting the inner wall of the guide groove, driving the locking plate to rotate. When the card block moves to the positioning groove, the locking plate will rotate and reset, driving the card block to automatically snap into the positioning groove, thereby realizing the superimposed fixation of the first pump body and the second pump body, ensuring the superimposed locking of the infusion pump, and subsequently by pressing and rotating the locking plate, the engagement of the card block and the positioning groove can be quickly released, thereby realizing the convenient disassembly of the first pump body and the second pump body.

[0028] like Figure 1-Figure 4 As shown, the first pump body 1 and the second pump body 2 are stacked and placed so that the connecting block 7 below the lower shell 4 of the first pump body 1 is slidably inserted into the guide groove 5 on the upper shell 3 of the second pump body 2, and the first pump body 1 is pushed so that the first pump body 1 and the second pump body 2 are stacked up and down, and when the positioning surface 12 on the connecting block 7 contacts the positioning surface 12 of the guide groove 5, the first pump body 1 and the second pump body 2 are precisely aligned, thereby improving the vertical stability after stacking.
