Description

Technical Field

[0001] This utility model relates to the field of measuring instruments, and in particular to a red blood cell lifespan measuring instrument. Background Technology

[0002] When storing the drying tube inside the existing measuring instrument, the drying tube is first fastened to the U-shaped buckle on one side of the measuring instrument, and then connected through the connecting tube. However, the measuring instrument will generate slight vibrations during operation, and because the connecting tube is a detachable connection, it has a certain degree of toughness and straightening ability, making it easy to detach from the connecting tube. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a red blood cell lifespan analyzer, which solves the technical problem that the connecting tube of the existing analyzer is easy to detach from the connecting tube because the connecting tube itself has a certain toughness and straightening ability.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a red blood cell lifespan analyzer, comprising a body, a test hole at the front end of the body, a control button on the top surface of the body, and a display panel on the top surface of the body near the control button. A pull plate is rotatably connected to one side of the body. Multiple drying tubes are arranged between the body and the pull plate. The drying tubes are filled with drying particles. A U-shaped buckle is provided on one side of the body to engage with the drying tubes. An extension tube is provided on the left side of each drying tube. A fixing mechanism for fixing the extension tube is provided on one side of the body. Connecting tubes are provided between the fixing mechanisms. The structure includes a connecting seat on one side of the machine body, a central shaft hole in the middle of the connecting seat, an inner tube rotatably disposed in the central shaft hole, a first fixing block on one side of the inner tube, a second fixing block on the other side of the inner tube, a tapered extrusion tube disposed inside the inner tube, a movable tube disposed inside the inner tube and screwed with the tapered extrusion tube, and a driving mechanism for driving the movable tube to move. The central shaft hole is coaxially arranged with the drying tube. The first fixing block and the second fixing block are detachably connected to the connecting seat. The inner diameter of the tapered extrusion tube gradually increases from one side to the other, and the outer diameter of the tapered extrusion tube gradually decreases from one side to the other. A shrinkage groove is provided on the outer side of the tapered extrusion tube.

[0005] Furthermore, the inner tube has an expansion surface that fits into the conical extrusion tube on the side near the shrinkage groove.

[0006] Furthermore, a positioning block is provided between the first fixing block and the inner tube, and the inner side of the positioning block is provided with a threaded groove that engages with the inner tube.

[0007] Furthermore, the driving mechanism includes a swing block rotatably disposed on one side of the connecting seat, a pull block disposed between the swing block and the moving tube, a moving block slidably disposed on the connecting seat, a handle rotatably disposed on the connecting seat, and a connecting rod disposed between the handle and the moving block. The moving block is rotatably connected to the swing block on the side away from the connecting rod, and the pull block is connected to the moving tube.

[0008] Furthermore, the moving tube is provided with a blocking outer ring on the side away from the conical extrusion tube, and a fixed ring is provided on the outside of the moving tube at a distance from the blocking outer ring. The pull block is located between the blocking outer ring and the fixed ring.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0010] In this erythrocyte lifespan analyzer, the drying tube is fastened to a U-shaped buckle at its center. After this, the drying tube is pushed towards the fixing mechanism, and the extension tube on one side of the drying tube is inserted into the conical extrusion tube. This is then used to activate the drive mechanism, which moves the moving tube towards the drying tube. The moving tube moves the conical extrusion tube, and the outer side of the conical extrusion tube is squeezed inward by the central shaft hole until the inner side of the conical extrusion tube is tightly fitted against the outer side of the extension tube. The conical extrusion tube in the central shaft hole provides a sealed connection to the drying tube. The connecting tube on the other side is fixed by adhesive or threaded connection, which ensures convenient replacement of the drying tube while preventing the connecting tube from falling off.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figures 1 to 6This embodiment provides a red blood cell life tester, including a body, a test hole 1 at the front end of the body, a control button 2 at the top surface of the body, and a display panel 3 at the top surface of the body and close to the control button 2. A pull plate 4 is rotatably connected to one side of the body. Multiple drying tubes 5 are provided between the body and the pull plate 4. The drying tubes 5 are filled with drying particles.

[0019] The machine body has a U-shaped buckle 6 on one side that engages with the drying tube 5. An extension tube 7 is located on the left side of the drying tube 5. A fixing mechanism 9 for fixing the extension tube 7 is located on the transverse side of the machine body. Connecting tubes 8 are connected between the fixing mechanisms 9. Each fixing mechanism 9 includes a connecting seat 901 on one side of the machine body, a central shaft hole 902 in the middle of the connecting seat 901, an inner tube 903 rotatably disposed within the central shaft hole 902, a first fixing block 904 on one side of the inner tube 903, a second fixing block 905 on the other side of the inner tube 903, and a connecting tube 8 on the inner tube 903. The inner tube 903 has a tapered extrusion tube 906, a movable tube 907 located inside the inner tube 903 and screwed onto the tapered extrusion tube 906, and a drive mechanism for moving the movable tube 907. The central shaft hole 902 is coaxially arranged with the drying tube 5. The first fixing block 904 and the second fixing block 905 are detachably connected to the connecting seat 901. The inner diameter of the tapered extrusion tube 906 gradually increases from one side to the other, and the outer diameter of the tapered extrusion tube 906 gradually decreases from one side to the other. The outer side of the tapered extrusion tube 906 is provided with a shrinkage groove 908.

[0020] The middle part of the drying tube 5 is fastened to the U-shaped buckle 6. After completion, the drying tube 5 is pushed to one side of the fixing mechanism 9. The extension tube 7 on one side of the drying tube 5 will be inserted into the conical extrusion tube 906. After completion, it is used to actuate the drive mechanism. The drive mechanism will drive the moving tube 907 to move towards the drying tube 5. The moving tube 907 drives the conical extrusion tube 906 to move. The outer side of the conical extrusion tube 906 will shrink inward due to the pressure of the central shaft hole 902 until the inner side of the conical extrusion tube 906 is tightly fitted to the outer side of the extension tube 7. The conical extrusion tube 906 in the central shaft hole 902 provides a sealing connection for the drying tube 5. The connecting tube 8 on the other side is fixed by adhesive or threaded connection. While maintaining the convenience of replacing the drying tube 5, it can also prevent the connecting tube 8 from falling off.

[0021] The inner tube 903 is provided with an expansion surface 909 on the side near the shrinkage groove 908, which fits into the conical extrusion tube 906, thus facilitating the guiding and fitting of the conical extrusion tube 906.

[0022] A positioning block 910 is provided between the first fixing block 904 and the inner tube 903, and the inner side of the positioning block 910 is provided with a threaded groove 911 that engages with the inner tube 903.

[0023] When installing the inner tube 903, insert the inner tube 903 into the central shaft hole 902, then screw the positioning block 910 onto the outside of the inner tube 903, and then fix the first fixing block 904 onto the connecting seat 901. The positioning block 910 facilitates the installation and fixing of the inner tube 903.

[0024] The driving mechanism includes a swing block 912 rotatably disposed on one side of the connecting seat 901, a pull block 913 disposed between the swing block 912 and the moving tube 907, a moving block 914 slidably disposed on the connecting seat 901, a handle 915 rotatably disposed on the connecting seat 901, and a connecting rod 916 disposed between the handle 915 and the moving block 914. The side of the moving block 914 away from the connecting rod 916 is rotatably connected to the swing block 912, and the pull block 913 is connected to the moving tube 907.

[0025] In use, after the extension tube 7 on one side of the drying tube 5 is inserted into the conical extrusion tube 906, pull the handle 915 downwards. The handle 915 drives the connecting rod 916 to move towards the conical extrusion tube 906. The connecting rod 916 drives the swing block 912 to rotate through the moving block 914. The swing block 912 drives the moving tube 907 to move laterally through the pull block 913, causing the conical extrusion tube 906 to move and retract into the inner tube 903. When it is necessary to disassemble the drying tube 5, simply pull the handle 915 upwards. It is convenient to use.

[0026] The moving tube 907 is provided with a blocking outer ring 917 on the side away from the conical extrusion tube 906. The moving tube 907 is provided with a fixed ring 918 spaced apart from the blocking outer ring 917. The pull block 913 is located between the blocking outer ring 917 and the fixed ring 918, which is conducive to limiting the pull block 913, thereby driving the pull block 913 to move.
