Description

Technical Field

[0001] This utility model relates to the field of intravenous needle technology, specifically to a quality testing device for intravenous needles. Background Technology

[0002] Intravenous needles are specialized needles used in medical procedures to puncture veins, primarily for intravenous infusions, blood draws, drug administration, or blood sample collection. Their core function is to establish a channel between the body and a vein, ensuring the efficient entry or exit of fluids, medications, or blood into or out of the body.

[0003] The demand for intravenous needles is increasing, but there is a lack of quality testing devices for them. For example, it is difficult to test whether the rigidity of the needles and the infusion volume meet the requirements. They can only be tested manually, which leads to large errors. Therefore, there is a need for a device that can automatically test the infusion volume to check whether the quality is up to standard.

[0004] Therefore, it is necessary to design a quality inspection device for intravenous needles that is both practical and capable of quality testing. Utility Model Content

[0005] The purpose of this invention is to provide a quality testing device for intravenous needles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection device for intravenous needles, comprising a base, a push rod mechanism rotatably connected above the base, a first connecting rod rotatably connected above the base, a second connecting rod rotatably connected to the end of the first connecting rod, an output end of the push rod mechanism rotatably connected to the end of the first connecting rod, a slide rail provided above the base, a slider slidably connected above the slide rail, a support plate provided above the slider, and the end of the second connecting rod rotatably connected to the support plate.

[0007] According to the above technical solution, a cylinder is provided above the support plate, a first detector is provided at the cylinder rod end, a first spring is provided at the detection end of the first detector, and a push rod is provided at the output end of the first detector.

[0008] According to the above technical solution, a second detector is provided at the end of the push rod, a detection rod is slidably connected inside the second detector, a second spring is provided on the outside of the detection rod, and a piston rod is provided at the end of the detection rod.

[0009] According to the above technical solution, a telescopic device is provided above the base, and a clamp is provided at the telescopic end of the telescopic device, with a syringe clamped on the inner side of the clamp.

[0010] According to the above technical solution, a second pushing component is provided above the base, a controller is provided at the sliding end of the second pushing component, a clamp is provided above the controller, and a limit plate is provided above the controller.

[0011] According to the above technical solution, an intravenous needle is provided above the clamp.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) The syringe is equipped with a clamp and a test liquid inside. The test liquid is pushed out by the piston rod. The flow rate is judged by the resistance when the test liquid is pushed out. If the flow rate is too small, the pushing resistance is large. If the flow rate is too large, the pushing resistance is small. The detection is started by triggering the first detector. The flow rate is judged by whether the second detector is triggered. Thus, it is determined whether the diameter of the intravenous needle is too small. If the first detection device is not triggered, it means that the diameter of the intravenous needle is too large.

[0014] (2) By setting a second detector, a piston rod is set at the end of the detection rod. The spring force of the second spring is greater than that of the first spring. When the push rod drives the piston rod forward, if the resistance is too great, the second spring will be compressed. At this time, the detection rod will be driven to retract into the second detector, which will trigger an alarm, indicating that the resistance is too great.

[0015] (3) By setting a first detector, the output end of the first detector is equipped with a push rod. The cylinder drives the first detector to move inward by pushing the internal air rod. When the first detector pushes the push rod to move inward, the first detector will be subject to resistance, which will compress the first spring and cause the moving ends of the first detector to touch each other, indicating that the resistance meets the requirements at this time.

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a quality detection device for intravenous needles, including a base 1, a pusher 2 rotatably connected above the base 1, a first connecting rod 3 rotatably connected above the base 1, a second connecting rod 6 rotatably connected to the end of the first connecting rod 3, the output end of the pusher 2 rotatably connected to the end of the first connecting rod 3, a slide rail 4 provided above the base 1, a slider 5 slidably connected above the slide rail 4, a support plate 7 provided above the slider 5, and the end of the second connecting rod 6 rotatably connected to the support plate 7. When the pusher 2 is activated, it pushes the end of the first connecting rod 3 to the right through the internal push rod, which will simultaneously move the top of the second connecting rod 6 to follow the displacement. At this time, the three parts cooperate to push the support plate 7 inward, causing the pain-sensing slider 5 to move inward on the slide rail 4, assisting in the preparation for subsequent detection.

[0022] A cylinder 8 is installed above the support plate 7. A first detector 9 is installed at the rod end of the cylinder 8. A first spring 10 is installed at the detection end of the first detector 9. A push rod 11 is installed at the output end of the first detector 9. The cylinder 8 drives the first detector 9 to move inward by pushing the internal rod. When the first detector 9 pushes the push rod 11 to move inward, the first detector 9 will be resisted, which will compress the first spring 10 and cause the movable ends of the first detector 9 to touch each other, which means that the resistance meets the requirements at this time.

[0023] A second detector 12 is provided at the end of the push rod 11. A detection rod 13 is slidably connected inside the second detector 12. A second spring 14 is provided on the outside of the detection rod 13. A piston rod 15 is provided at the end of the detection rod 13. The elastic force of the second spring 14 is greater than that of the first spring 10. When the push rod 11 drives the piston rod 15 forward, if the resistance is too great, the second spring 14 will be compressed. At this time, the detection rod 13 will be driven to retract into the second detector 12, which will trigger an alarm, indicating that the resistance is too great.

[0024] A telescopic device 16 is provided above the base 1. A clamping plate 17 is provided at the telescopic end of the telescopic device 16. A syringe 18 is clamped on the inner side of the clamping plate 17. The syringe 18 contains test liquid. The test liquid is pushed out by the piston rod 15. The flow rate is judged by the resistance when the test liquid is pushed out. If the flow rate is too small, the pushing resistance is large. If the flow rate is too large, the pushing resistance is small. The detection is started by triggering the first detector 9. Whether the second detector 12 is triggered determines whether the flow rate is too small, thereby determining whether the diameter of the intravenous needle 23 is too small. If the first detection device 9 is not triggered, it means that the diameter of the intravenous needle 23 is too large.

[0025] A second pushing component 19 is provided above the base 1. A controller 20 is provided at the sliding end of the second pushing component 19. A clamp 22 is provided above the controller 20. A limit plate 21 is provided above the controller 20. The controller 20 controls the clamp 22 to rise, and the clamp 22 clamps and fixes the intravenous needle 23. The second pushing component 19 and the front pushing component are used to connect the syringe 18 and the intravenous needle 23, thereby starting the detection.

[0026] A vein needle 23 is provided above the gripper 22 for detection.
