Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and specifically discloses a hemolysis identification device. Background Technology
[0002] Blood banks store blood of various blood types, and blood is retrieved from the blood bank when a transfusion is needed. The blood bags stored in the blood bank are considered stock blood. If contamination occurs during blood collection, or if temperature and humidity are not strictly controlled during transportation and storage, hemolysis may occur. Using hemolyzed blood bags during transfusion can affect the patient's health and safety.
[0003] Traditional identification methods often rely on direct visual inspection, which is not only less accurate and difficult to accurately judge mild hemolysis, but also lacks a unified and objective standard for defining the degree of hemolysis, which can easily lead to misjudgment and pose potential risks to medical safety. Therefore, a hemolysis identification device is needed to solve this problem. Utility Model Content
[0004] This invention proposes a hemolysis identification device, which forms a dual identification logic of "microscopic feature observation + standard color mark comparison" through both identification structure and colorimetric structure. This significantly improves the comprehensiveness and reliability of hemolysis identification, confirming the existence of hemolysis and accurately defining its severity.
[0005] This utility model is implemented as follows: a hemolysis identification device includes a base, a sample placement platform on the base, a top plate above the base, a lifting mechanism between the upper surface of the base and the top plate, an identification structure above the base via the lifting mechanism, and a colorimetric structure behind the upper surface of the base.
[0006] The identification structure includes a movable plate set above the base, a mounting frame fixedly connected to the movable plate, a magnifying glass set inside the mounting frame, sliding grooves opened on the outer walls of both ends of the movable plate, a slider slidably connected to the outer wall of the movable plate through the sliding grooves, and an LED light installed at the bottom of the slider.
[0007] The colorimetric structure includes a mounting plate fixedly connected to the rear of the upper end face of the base, a colorimetric chuck rotatably connected to the front end face of the mounting plate, and a screw rod that passes through and is threadedly connected to the outer wall of the mounting plate and is fixedly connected to the colorimetric chuck.
[0008] As a preferred embodiment of the hemolysis identification device of this utility model, the lifting mechanism includes a threaded rod rotatably connected between the base and the top plate and threadedly connected to the moving plate, a slide rod fixedly connected between the base and the top plate and slidably connected to the moving plate, and a stepper motor installed on the upper surface of the top plate and whose output end is fixedly connected to the threaded rod.
[0009] As a preferred embodiment of the hemolysis identification device of this utility model, the rear end face of the sample placement stage is provided with a notch corresponding to the position of the colorimetric cassette.
[0010] As a preferred embodiment of the hemolysis identification device of this utility model, a transparent shell covering the colorimetric cassette is provided in front of the mounting plate.
[0011] In a preferred embodiment of the hemolysis identification device of this utility model, the top end of the slider is threadedly connected to a locking bolt, and the threaded end of the locking bolt abuts against the surface of the moving plate.
[0012] As a preferred embodiment of the hemolysis identification device of this utility model, the bottom end of the base is provided with an anti-slip pad.
[0013] The beneficial effects of this utility model are:
[0014] 1. Examine the blood bag on the sample placement stage with a magnifying glass, and move the slider to move the LED light to ensure that the sample is observed under the best lighting conditions, thereby improving the accuracy of identification. Furthermore, the identification structure can enhance the illumination and magnify the sample for observation, significantly improving the identification accuracy of hemolysis.
[0015] 2. By rotating the screw, the colorimetric chuck can be switched to different standard color levels for different degrees of hemolysis.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0023] Please see Figure 1-3 The hemolysis identification device includes a base 1, a sample placement platform 2 on the base 1, a top plate 101 above the base 1, a lifting mechanism between the upper end face of the base 1 and the top plate 101, an identification structure above the base 1 via the lifting mechanism, and a colorimetric structure behind the upper end face of the base 1.
[0024] The identification structure includes a movable plate 5 disposed above the base 1, a mounting frame 501 fixedly connected to the movable plate 5, a magnifying glass 502 disposed inside the mounting frame 501, a sliding groove formed on the outer wall of both ends of the movable plate 5, a slider 6 slidably connected to the outer wall of the movable plate 5 through the sliding groove, and an LED light 601 installed at the bottom of the slider 6.
[0025] The colorimetric structure includes a mounting plate 3 fixedly connected to the rear of the upper end face of the base 1, a colorimetric chuck 302 rotatably connected to the front end face of the mounting plate 3, and a screw 303 that passes through and is threadedly connected to the outer wall of the mounting plate 3 and is fixedly connected to the colorimetric chuck 302.
[0026] In this embodiment: the blood bag to be identified is placed on the sample placement stage 2, and then the moving plate 5 is driven to move down by the lifting mechanism until the position of the moving plate 5 is adapted to the height of the operator. Then, the blood bag on the sample placement stage 2 is viewed through the magnifying glass 502, and the sliding slider 6 is moved to drive the LED light 601 to ensure that the sample is observed under the best lighting conditions, thereby improving the identification accuracy. Furthermore, the identification structure can enhance the illumination and magnify the observation of the sample, significantly improving the identification accuracy of hemolysis.
[0027] By comparing the standard color scales marked with different hemolysis levels on the color chuck 302, rotating the screw 303 can switch the standard color scales of different hemolysis levels. The notch 201 of the sample placement stage 2 makes the color scales of the blood bag and the color chuck 302 in the same field of view, which is convenient for direct comparison. Furthermore, the colorimetric structure aligns the standard color mark with the sample position, allowing direct comparison of the blood bag color with the standard color scale, which greatly improves the convenience and accuracy of the colorimetric operation and quickly completes the identification of the degree of hemolysis.
[0028] Furthermore, by combining structural identification and colorimetric analysis, a dual identification logic of "microscopic feature observation + standard color mark comparison" is formed, which significantly improves the comprehensiveness and reliability of hemolysis identification, confirming the existence of hemolysis and accurately defining its severity.
[0029] As a technical optimization of this utility model, the lifting mechanism includes a threaded rod 4 rotatably connected between the base 1 and the top plate 101 and threadedly connected to the moving plate 5, a slide rod fixedly connected between the base 1 and the top plate 101 and slidably connected to the moving plate 5, and a stepper motor 401 installed on the upper surface of the top plate 101 and whose output end is fixedly connected to the threaded rod 4.
[0030] In this embodiment: the stepper motor 401 is started, which drives the threaded rod 4 to rotate, causing the moving plate 5 to move up and down on the outer wall of the slide rod, thereby adjusting the position of the recognition mechanism to suit the use of staff of different heights.
[0031] As a technical optimization of this utility model, the rear end face of the sample placement stage 2 is provided with a notch 201 corresponding to the position of the colorimetric chuck 302.
[0032] In this embodiment, the notch 201 allows the sample and the colorimetric cassette 302 to be within the corresponding field of view. The operator can directly compare the color of the sample with the standard color on the colorimetric cassette 302 through the notch 201 without moving the sample or adjusting their own position, thereby quickly determining the hemolysis status of the sample and improving the convenience and accuracy of the colorimetric operation.
[0033] As a technical optimization of this utility model, a transparent shell 301 covering the colorimetric chuck 302 is provided in front of the mounting plate 3.
[0034] In this embodiment: the transparent shell 301 can prevent external dust, moisture and other contaminants from contaminating or damaging the color matching chuck 302, thus playing a protective role; on the other hand, the transparent material will not obstruct the view, making it convenient for staff to clearly see the colors on the color matching chuck 302, ensuring the smooth progress of the color matching work.
[0035] As a technical optimization of this utility model, the top of the slider 6 is threaded with a locking bolt, and the threaded end of the locking bolt abuts against the surface of the moving plate 5.
[0036] In this embodiment, the position of slider 6 can be locked by tightening the bolt.
[0037] As a technical optimization of this utility model, an anti-slip pad is provided at the bottom of the base 1.
[0038] In this embodiment: the anti-slip pad can increase the friction of the base 1, so that the base 1 can be placed stably.
[0039] The working principle and usage process of this utility model are as follows: Place the blood bag to be identified on the sample placement stage 2, then start the stepper motor 401 to drive the threaded rod 4 to rotate, causing the moving plate 5 to move downward on the outer wall of the slide rod, driving the moving plate 5 to move down until the position of the moving plate 5 is suitable for the operator's height. Then, use the magnifying glass 502 to view the blood bag on the sample placement stage 2, and move the slider 6 to drive the LED light 601 to move, ensuring that the sample is observed under the best lighting conditions.
[0040] Furthermore, by using the standard color scales marked with different hemolysis levels on the color chuck 302, rotating the screw 303 can switch between standard color scales with different hemolysis levels. The notch 201 of the sample placement stage 2 ensures that the color scales of the blood bag and the color chuck 302 are in the same field of view, facilitating direct comparison. In addition, the colorimetric structure aligns the standard color mark with the sample position, allowing direct comparison of the blood bag color with the standard color scale, which greatly improves the convenience and accuracy of the colorimetric operation.
