Description

Technical Field

[0001] This utility model relates to the technical field of infusion testing, and in particular to a device for detecting the color and concentration of finished infusion solutions in an intravenous medication preparation center. Background Technology

[0002] Intravenous infusion is a commonly used method of drug administration in clinical practice and an important means of disease diagnosis and treatment. my country is a major country for intravenous infusion; statistics show that the proportion of inpatients receiving intravenous infusion in hospitals at level two and above is as high as 65%-85%. The hospital's intravenous medication preparation center (IVPCC) is the department responsible for the centralized preparation of intravenous infusions. Through steps such as reviewing medication orders, mixing and preparing medications, and verifying finished products, IVPCC staff can provide clinicians with high-quality, directly injectable finished infusion solutions. Strict quality control and providing qualified finished infusion solutions to clinicians are the responsibilities of the IVPCC. Checking the appearance of finished infusion solutions for discoloration and the accuracy of the drawn medication volume are important aspects of finished infusion solution quality inspection. However, IVPCCs prepare thousands of bags (bottles) of finished infusion solutions daily. Manual quality inspection of finished infusion solutions is inefficient, and long working hours can easily lead to fatigue, resulting in a lower detection rate of substandard products and endangering patient medication safety.

[0003] Most testing equipment on the market is currently an independent unit, lacking systematic integration and collaboration. When testing drugs, it is often necessary to operate and test them one by one, which is not only inefficient, but also prone to introducing additional errors due to the cumbersome operation. At the same time, the detection accuracy of these testing devices is often difficult to guarantee under the influence of external environmental conditions, such as temperature, humidity, and light.

A short hook 23 is fixedly installed on the lower end face of the bottom sealing cover 22. A support bar 24 is fixedly installed on the upper end face of the bottom sealing cover 22. The upper end of the support bar 24 is rotatably connected to the flip plate 26.

Both ends of the threaded rod III 32 are connected to the support base plate 14 via baffles. A motor is connected to one end of the threaded rod III 32, which drives the threaded rod III 32 to rotate, thereby moving the cylinder sliding frame 31. The cylinder III 34 is fixedly installed on the cylinder sliding frame 31, and a short hook connecting frame 33 is fixedly installed on the upper end of the cylinder III 34. The short hook connecting frame 33 works in conjunction with the bottom sealing cover 22. In use, the short hook connecting frame 33 wraps around the outside of the short hook 23. The discharge belt assembly 35 consists of multiple belts, arranged on one side for transporting good products, transporting one type of defective belt, and transporting all defective belts.

[0050] Working principle: This equipment is used when it is necessary to detect the color and concentration of medicine in an infusion bag. First, the infusion bag containing the medicine is placed on the feeding belt 1. Then, the feeding belt 1 puts the infusion bag into the light shield box 18 corresponding to the feeding belt 1. Then, the motor connected to the rotating main shaft 36 drives the rotating main shaft 36 to rotate, which in turn drives the material conveying bracket 15 to rotate, thereby driving the light shield box 18 to rotate. The light shield box 18 containing the infusion bag is rotated to the position of the connecting rod 30, so that the protrusion on the connecting rod 30 is engaged in the groove on the outer slide rod of the material conveying bracket 15 to connect the connecting rod 30 to the material conveying bracket 15. At the same time, when the light shield box 18 is rotated to the position, the long hook 21 enters the middle of the long hook connecting frame 28.

[0051] At this time, the motor connected to the connecting rod 30 drives the connecting rod 30 to rotate back and forth in a small range, which in turn drives the material conveying bracket 15 to shake back and forth in a small range, thereby driving the light shield box 18 to shake back and forth in a small range. After shaking, the cylinder II 29 drives the long hook connecting frame 28 to move down, and then drives the light shield box 18 to move down through the long hook 21. After moving down, the cylinder II 29 suddenly moves in the opposite direction, and then drives the long hook connecting frame 28 to move in the opposite direction, so that the light shield box 18 bounces back in the opposite direction under the action of the tension spring 20, thereby vibrating the infusion bag in the light shield box 18, and shaking and swaying the infusion bag in the light shield box 18 back and forth, thereby shaking the medicine in the infusion bag evenly and spreading it flat on the flip plate 26 provided at the bottom of the light shield box 18.

[0052] Then, the main shaft 36 is rotated to drive the light shield box 18 to the position of the sealing detection cover 4. The cylinder I3 drives the detection plate 2 to move down, and then drives the sealing detection cover 4 to cover the upper end of the light shield box 18. Then, the LED light source 5 and the industrial camera 6 are used for color detection. After the detection is completed, the cylinder I3 drives the detection plate 2 to move up so that the sealing detection cover 4 is separated from the light shield box 18.

[0053] Then, rotating the main shaft 36 drives the light-shielding box 18 to the position of the moving detection box 8. The cylinder I3 drives the detection plate 2 to move down, which in turn drives the moving detection box 8 to cover the upper end of the light-shielding box 18. At this time, the fiber optic probe 9 enters the light-shielding box 18 and comes into contact with the infusion bag.

[0054] Then, the concentration is detected by the fiber optic probe 9 and the spectrometer 10. After the detection is completed, the cylinder I3 moves upward to separate the moving detection box 8 from the light shield box 18, and the fiber optic probe 9 is taken out from the light shield box 18.

[0055] Then, the main shaft 36 is rotated to drive the light shield box 18 to the position of the short hook connecting frame 33. At this time, the short hook 23 enters the middle position of the short hook connecting frame 33. Then, the cylinder III 34 drives the short hook connecting frame 33 to move down, and then drives the short hook 23 to move down, thereby driving the flip plate 26 to move down. Under the action of the spring rod 27, the flip plate 26 is flipped. When one end of the flip plate 26 slides out of the light shield box 18, the infusion bag on the flip plate 26 slides off the detection plate 2 onto the discharge belt assembly 35 and is transported to the designated position.

[0056] When the color is detected by the sealed detection cover 4, LED light source 5 and industrial camera 6, the light shield box 18 remains stationary when the detection is good, and when the detection is bad, the threaded rod II 16 drives the moving sleeve 17 to move, thereby driving the light shield box 18 to move in the groove provided in the material conveying bracket 15. At the same time, the feeding belt 1 rotates and drives the moving detection box 8 to the middle position of the guide box 7, so as to overlap with the light shield box 18 that has moved to the middle position of the material conveying bracket 15.

[0057] After the concentration detection of the moving detection box 8, the fiber optic probe 9 and the spectrometer 10 is completed, the light shield box 18 remains stationary when the detection is good. When the detection is bad, the threaded rod II 16 drives the moving sleeve 17 to move, thereby driving the light shield box 18 to move in the material conveying bracket 15 with a sliding groove. Then, during the rotation of the rotating spindle 36, the light shield box 18 is rotated. At the same time, the threaded rod III 32 drives the cylinder sliding frame 31 to move, which in turn drives the short hook connecting frame 33 and the cylinder III 34 to move to the designated position for easy connection with the short hook 23.
