Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and more specifically, to a quick-connect and quick-release structure for an injection tube used in a micro-infusion pump for cardiology. Background Technology

[0002] A micro-infusion pump is a new type of pumping instrument that mainly consists of a controller, an actuator, and a syringe. Because micro-infusion pumps can deliver small amounts of fluid precisely, in minute quantities, uniformly, and continuously into the patient's body, they are of great importance in clinical departments such as cardiology.

[0003] Micro-infusion pumps deliver liquid precisely and stably to the target location by driving a piston component within the pump body to reciprocate. This motion can be controlled by adjusting parameters such as motor speed, vibration frequency, or pressure difference to regulate the flow rate and pressure of the liquid, allowing for adjustments to drug concentration and speed as needed based on the patient's condition, thus maintaining an effective blood drug concentration.

[0004] Currently, when using micro-infusion pumps, the syringe's rolled edge is usually snapped into an arc-shaped groove to complete the syringe installation. However, after the syringe is snapped in, there is usually a certain gap between the inner wall of the groove and the rolled edge. When injecting, the pressure applied by the plunger will push the syringe body until the rolled edge and the inner wall of the groove are tightly fitted. Although this slight shaking does not affect the continuous injection, it will affect the micro-infusion pump's calculation of the total injection volume. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a quick-connect and quick-disconnect structure for the injection tubing of a micro-infusion pump in cardiology, which has the advantages of quick assembly and disassembly and stable installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect and quick-disconnect structure for an injection tube of a cardiology micro-infusion pump, comprising a micro-infusion pump, an operation panel on the top of the micro-infusion pump, a fixed platform fixedly mounted on the front side of the micro-infusion pump, a push rod on the right side of the fixed platform, the push rod and the push head being fixedly connected, an arc-shaped groove on the front side of the fixed platform, a slot inside the fixed platform, and a clamping plate movably mounted inside the slot;

[0007] A guide cylinder is fixedly installed on the front side of the fixed platform. A pressure block is sleeved on the outer wall of the guide cylinder. One end of the pressure block is fixedly connected to the transmission rod. The pressure block and the inner wall of the guide cylinder are elastically connected by a spring. The transmission rod passes through the interior of the micro pump and is connected to the gear transmission. A bracket is fixedly installed inside the micro pump. A gear is rotatably installed on one end of the bracket. A bevel gear one is rotatably installed on the other end of the bracket. The gear and bevel gear one are fixedly connected. A bevel gear two is fixedly installed on the inner wall of the micro pump. The bevel gear two meshes with bevel gear one. The bevel gear two is fixedly connected to gear shaft two. The gear shaft two is rotatably installed inside the slot.

[0008] As a preferred embodiment of the present invention, the card slot has an internal movable groove;

[0009] A rotating shaft is rotatably mounted inside the movable groove. A gear shaft is fixedly mounted in the middle of the rotating shaft. The gear shaft and gear shaft are connected in a transmission manner. A pressure plate is rotatably mounted on the outer wall of the rotating shaft.

[0010] As a preferred embodiment of this utility model, the pusher head has a positioning hole inside, which is responsible for fixing the syringe piston.

[0011] As a preferred embodiment of this utility model, both the upper and lower ends of the front side of the clamping plate are fixedly installed with protrusions, and the protrusions extend to the outside of the slot.

[0012] As a preferred embodiment of this utility model, the rear end of the transmission rod is provided with teeth, and the transmission rod is connected to the gear through the teeth.

[0013] As a preferred embodiment of this utility model, a torsion spring is elastically provided on the outer wall of the rotating shaft, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a pressure block to drive a transmission rod to move. At this time, the transmission rod drives a gear to rotate through teeth. Furthermore, the second bevel gear and the second gear shaft rotate synchronously. At this time, the second gear shaft drives the first gear shaft to rotate, causing the pressure plate to be housed inside the movable groove. After the operator fixes the syringe, the syringe is clamped by the elastic potential energy of the spring. Compared with the traditional device, this device can complete the syringe clamping by pulling the pressure block outward. By releasing the pressure block, the pressure block and the clamping plate clamp the syringe firmly to prevent it from shaking, thus ensuring the calculation of the total injection volume by the micro-pump.

[0016] 2. This utility model utilizes the elastic potential energy of the torsion spring to provide a compensation amount to the pressure plate when the clamping plate is fixed and can no longer move to the left. This prevents the pressure plate from continuing to operate and causing damage to the parts. Compared with traditional devices, this device can use the pressure plate to push the clamping plate to fix the syringe curled edge to the left side of the slot, preventing shaking and improving injection accuracy.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 7As shown, this utility model provides a quick-connect and quick-disconnect structure for an injection tube of a micro-infusion pump in cardiology, including a micro-infusion pump 1, an operation panel 2 on the top of the micro-infusion pump 1, a fixed platform 3 fixedly installed on the front side of the micro-infusion pump 1, a push rod 4 on the right side of the fixed platform 3, the push rod 4 and the push head 5 fixedly connected, an arc-shaped groove 8 is opened on the front side of the fixed platform 3, a slot 6 is opened inside the fixed platform 3, and a clamping plate 7 is movably installed inside the slot 6;

[0027] A guide cylinder 9 is fixedly installed on the front side of the fixed platform 3. A pressure block 10 is sleeved on the outer wall of the guide cylinder 9. One end of the pressure block 10 is fixedly connected to the transmission rod 12. The pressure block 10 and the inner wall of the guide cylinder 9 are elastically connected by a spring 11. The transmission rod 12 passes through the interior of the micro pump 1 and is connected to the gear 14. A bracket 16 is fixedly installed inside the micro pump 1. A gear 14 is rotatably installed on one end of the bracket 16. A bevel gear 15 is rotatably installed on the other end of the bracket 16. The gear 14 and the bevel gear 15 are fixedly connected. A bevel gear 25 is fixedly installed on the inner wall of the micro pump 1. The bevel gear 25 and the bevel gear 15 mesh with each other. The bevel gear 25 is fixedly connected to the gear shaft 22. The gear shaft 22 is rotatably installed inside the slot 6.

[0028] When the micro-infusion pump 1 is needed to administer an injection to a patient, the operator first positions the micro-infusion pump 1 in the appropriate position and draws sufficient medication into the syringe. Then, the operator pulls out the pressure block 10, which drives the transmission rod 12 to move. The transmission rod 12 further drives the gear 14 to rotate via the teeth 13. The gear 14 is fixedly connected to the first bevel gear 15, causing the first bevel gear 15 to rotate. The first bevel gear 15 then drives the second bevel gear 25 to rotate. The second bevel gear 25 and the second gear shaft 22 rotate synchronously. At this time, the second gear shaft 22 drives the first gear shaft 20 to rotate, causing the pressure plate 19 to be retracted into the movable groove 17. Then, the operator uses the protrusion... 24. Push the clamping plate 7 to the right side of the slot 6 and engage the syringe barrel in the arc groove 8, so that the syringe crimp is engaged inside the slot 6. Then, the operator releases the pressure block 10. At this time, the elastic potential energy of the spring 11 drives the pressure block 10 to reset, so that the transmission rod 12 drives the gear 14 to reverse through the teeth 13, and further drives the gear shaft 20 to reverse through the transmission gear shaft 22, so that the pressure plate 19 rotates to the outside of the movable groove 17 and abuts against the clamping plate 7, so that the clamping plate 7 clamps the syringe crimp. Then, the operator aligns the positioning hole 23 with the syringe piston rod and starts the micro pump 1, so that the push rod 4 drives the push head 5 to move and perform the injection operation.

[0029] The pressure block 10 drives the transmission rod 12 to move. At this time, the transmission rod 12 drives the gear 14 to rotate through the teeth 13. Furthermore, the bevel gear 25 and the gear shaft 22 rotate synchronously. At this time, the gear shaft 22 drives the gear shaft 20 to rotate, so that the pressure plate 19 is stored in the movable groove 17. After the operator fixes the syringe, the elastic potential energy of the spring 11 clamps the syringe. Compared with the traditional device, this device can complete the syringe clamping by pulling the pressure block 10 outward. By releasing the pressure block 10, the pressure block 10 and the clamping plate 7 clamp the syringe firmly to prevent it from shaking, thus ensuring the calculation of the total injection volume by the micro-pump 1.

[0030] The card slot 6 has an internal movable slot 17;

[0031] A rotating shaft 18 is rotatably mounted inside the movable groove 17. A gear shaft 20 is fixedly mounted in the middle of the rotating shaft 18. The gear shaft 20 and the gear shaft 22 are connected for transmission. A pressure plate 19 is rotatably mounted on the outer wall of the rotating shaft 18.

[0032] After the operator releases the pressure block 10, the pressure plate 19 rotates to the outside of the movable groove 17 and abuts against the clamping plate 7, so that the clamping plate 7 clamps the syringe edge. At this time, when encountering a larger syringe, its edge is thicker. After the pressure plate 19 pushes the clamping plate 7 to fix the edge, the rotating shaft 18 will continue to rotate. The rotating shaft 18 uses the elastic potential energy of the torsion spring 21 to stop the pressure plate 19 from rotating and continuously squeezes the clamping plate 7 to ensure the fixation of the syringe.

[0033] By utilizing the elastic potential energy of the torsion spring 21, when the clamping plate 7 is fixed and can no longer move to the left, the torsion spring 21 will provide a compensation amount for the pressure plate 19, preventing the pressure plate 19 from continuing to operate and causing damage to the parts. Compared with conventional devices, this device can use the pressure plate 19 to push the clamping plate 7 to fix the syringe curled edge to the left side of the slot 6, preventing shaking and improving injection accuracy.

[0034] The pusher 5 has a positioning hole 23 inside, which is responsible for fixing the syringe piston.

[0035] The staff aligns the positioning hole 23 with the syringe piston rod and starts the micro-pump 1, causing the push rod 4 to drive the push head 5 to move and perform the injection operation.

[0036] The clamping plate 7 has protrusions 24 fixedly installed at both the upper and lower ends of its front side, and the protrusions 24 extend to the outside of the slot 6.

[0037] The operator can move the clamping plate 7 to the right side of the slot 6 via the protrusion 24 to facilitate the clamping of the syringe curl.

[0038] The transmission rod 12 has teeth 13 at its rear end, and the transmission rod 12 is connected to the gear 14 through the teeth 13.

[0039] The outer wall of the rotating shaft 18 is elastically provided with a torsion spring 21. One end of the torsion spring 21 is fixedly connected to the rotating shaft 18, and the other end is fixedly connected to the pressure plate 19.

[0040] After the pressure plate 19 pushes the clamping plate 7 to fix the rolled edge, the rotating shaft 18 will continue to rotate. The rotating shaft 18 uses the elastic potential energy of the torsion spring 21 to stop the pressure plate 19 from rotating and continuously squeezes the clamping plate 7 to ensure the fixation of the syringe.

[0041] Working principle and usage process of this utility model:

[0042] When the micro-infusion pump 1 is needed to administer an injection to a patient, the operator first positions the micro-infusion pump 1 in the appropriate position and draws sufficient medication into the syringe. Then, the operator pulls out the pressure block 10, which drives the transmission rod 12 to move. The transmission rod 12 further drives the gear 14 to rotate via the teeth 13. The gear 14 is fixedly connected to the first bevel gear 15, causing the first bevel gear 15 to rotate. The first bevel gear 15 then drives the second bevel gear 25 to rotate. The second bevel gear 25 and the second gear shaft 22 rotate synchronously. At this time, the second gear shaft 22 drives the first gear shaft 20 to rotate, causing the pressure plate 19 to be retracted into the movable groove 17. Then, the operator uses the protrusion... 24. Push the clamping plate 7 to the right side of the slot 6 and engage the syringe barrel in the arc groove 8, so that the syringe crimp is engaged inside the slot 6. Then, the operator releases the pressure block 10. At this time, the elastic potential energy of the spring 11 drives the pressure block 10 to reset, so that the transmission rod 12 drives the gear 14 to reverse through the teeth 13, and further drives the gear shaft 20 to reverse through the transmission gear shaft 22, so that the pressure plate 19 rotates to the outside of the movable groove 17 and abuts against the clamping plate 7, so that the clamping plate 7 clamps the syringe crimp. Then, the operator aligns the positioning hole 23 with the syringe piston rod and starts the micro pump 1, so that the push rod 4 drives the push head 5 to move and perform the injection operation.

[0043] After the operator releases the pressure block 10, the pressure plate 19 rotates to the outside of the movable groove 17 and abuts against the clamping plate 7, so that the clamping plate 7 clamps the syringe edge. At this time, when encountering a larger syringe, its edge is thicker. After the pressure plate 19 pushes the clamping plate 7 to fix the edge, the rotating shaft 18 will continue to rotate. The rotating shaft 18 uses the elastic potential energy of the torsion spring 21 to stop the pressure plate 19 from rotating and continuously squeezes the clamping plate 7 to ensure the fixation of the syringe.
