Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to a device for semi-automatic stoppering of test tubes in laboratories with large specimen quantities and centralized testing. Background Art

[0002] Test tubes and test tube stoppers are commonly used items in the field of medical testing. Test tubes are containers for storing test substances such as blood and body fluids. Test tube stoppers are usually made of rubber or plastic. Their purpose is to seal the test tubes to prevent the contents from being contaminated or volatilized, and to ensure the quality of the preserved specimens. In daily laboratory operations, it is necessary to reinstall new test tube stoppers on test tubes that have completed testing and contain the remaining test substances.

[0003] At present, in most cases, this operation is performed manually without any auxiliary devices. That is, the operator takes out the test tube with one hand, takes out a new test tube plug from the bag with the other hand, presses it into the test tube with the thumb, and then places the test tube into the test tube rack. Some institutions have designed electric plugging machines, which have electric motors and sensors and use mechanical devices to replace manual labor, but they still use a single test tube capping. Large-scale laboratories use assembly lines with plugging devices, which are part of the assembly line module. Although they are efficient, they are generally not used alone, and the cost is too high.

[0004] Manually adding stoppers to test tubes is time-consuming and laborious, and can easily cause biosafety exposure. Time-consuming here means that operators need to add stoppers to test tubes one by one, which is inefficient and prolongs working hours; laborious means that only fingers can be used to add stoppers, which can easily cause fatigue, resulting in slower work efficiency or forced termination; prone to biosafety exposure means that if the test tube breaks during the manual stoppering process, it will cause damage to the fingers of personnel, resulting in infection. Automatic stoppering equipment is suitable for assembly lines, but there are price and convenience issues. Price here refers to a significant increase in costs, and it is not suitable for small and medium-sized laboratories; convenience refers to the inability to flexibly meet the stoppering needs in various situations. Similarly, fully automatic stoppering equipment may cause test tubes to break during assembly line work, thereby affecting the work efficiency of the entire assembly line. Summary of the invention

[0039] Test tubes and test tube plugs are commonly used items in the field of medical testing. Test tubes are containers for storing substances to be tested, such as blood and body fluids. Test tube plugs are usually made of rubber or plastic. Their purpose is to seal the test tubes to prevent the contents of the test tubes from being contaminated or volatilized, and to ensure the quality of the preserved specimens. In daily laboratory operations, it is necessary to reinstall new test tube plugs on the test tubes of the remaining substances to be tested that have completed the test. At present, in most cases, this operation is performed purely manually without any auxiliary devices. That is, the operator takes out the test tube with one hand, takes out a new test tube plug from the bag with the other hand, presses it into the test tube with the thumb, and then places the test tube in the test tube rack. Some institutions have designed an electric plugging machine, which has an electric motor and a sensor, and replaces manual labor with a mechanical device, but still uses a single capping of one test tube. Large-scale laboratories use assembly lines with plugging devices, which are part of the assembly line module. Although they are highly efficient, they are generally not used alone, but the cost is too high.

[0040] In view of this, the present invention proposes a semi-automatic medical test tube plugging device, please refer to Figure 1The semi-automatic medical test tube plugging device 100 comprises a chassis 1, a test tube plug filling device 2 and a plug pressing device 3. A plugging station 11 is provided on the left side of the chassis 1, and a plug pressing station 12 is provided on the right side. A plugging box 111 is provided at the plugging station 11. An upper plug opening 1111 is provided at the upper cover of the chassis 1 and corresponds to the plugging station 11. The test tube plug filling device 2 is provided in the upper plug box 111. The test tube plug filling station 2 comprises a test tube plug roller 21 and a test tube plug plate 22. The test tube plug plate 22 A plurality of plug plate holes are provided on the upper portion, and a test tube plug roller 21 is arranged near the upper portion of the test tube plug plate 22, for rolling the test tube plugs in the upper plug box 111, and driving the test tube plugs to fill them into the test tube plug holes 221; a plugging device 3 is arranged at the plugging station 12, and the plugging device 3 has a plugging portion 31 located above the test tube, and the plugging portion 31 has an active stroke in the up and down direction when driven, so as to press the test tube plugs in the test tube plug plate 22 located below the plugging portion 31 into the test tube.

[0041] It should be noted here that the overall frame of the device is made of hard metal, the test tube rack 4 and the test tube plug are both commercially available items, the test tube plug roller 21 can be made of light metal hard material or hard plastic, and the test tube plug plate 22 can be made of hard metal or other pressure-resistant materials. Among them, the diameter of the test tube plug hole 221 on the test tube plug plate 22 is slightly larger than the diameter of a common test tube, but slightly smaller than the large circular surface of the test tube plug. The diameter slightly larger than the diameter of a common test tube is used to fix the test tube when pressing the test tube plug, and slightly smaller than the large circular surface of the test tube plug to ensure that the test tube plug falls into the test tube plug hole 221 in the correct way and does not fall from the test tube plug hole 221.

[0042] Furthermore, in order to facilitate driving the test tube plug roller 21 to rotate, the test tube plug roller 21 includes a roller shaft 211 arranged along its axial direction, the roller shaft 211 is fixedly connected to the test tube plug roller 21, and one end of the roller shaft 211 is exposed from the bottom surface of the test tube plug roller 21; the exposed end of the roller shaft 211 is connected to the motor 23 to drive the test tube plug roller 21 to rotate. Of course, a handle can also be added to the roller shaft 211 for manual plugging, and the motor 23 is used for more automation. Of course, when the motor 23 is used to drive the test tube plug roller 21 to rotate, a switch 24 and a power cord 25 electrically connected to the switch 24 are also provided on the chassis 1.

[0043] See also Figure 2 and Figure 3In order to better drive the test tube plugs to roll, a roller protrusion 212 is provided on the side of the test tube plug roller 21, so as to facilitate filling the test tube plugs in the upper plug box 111 into the test tube plug holes 221; the extension direction of the roller protrusion 212 is parallel to the axial direction of the test tube plug roller 21. The extension direction or shape and size of the rolling protrusion here are related to the distribution of the test tube plug holes 221 of the test tube plug plate 22. Since most of the test tube racks 4 are arranged in a matrix, in this embodiment, the test tube plug holes 221 are also distributed in a matrix on the test tube plug plate 22, that is, the roller protrusion 212 is preferably linear, and the extension direction is parallel to the axial direction of the test tube plug roller 21.

[0044] Preferably, see Figure 1 The chassis 1 further includes a card slot 13 arranged along the left-right direction, and the test tube plug plate 22 is movably arranged in the card slot 13, and has a movable stroke from the plugging station 11 to the plugging station 12.

When the test tube plug plate 22 moves to the plugging station 12, the next test tube plug plate 22 is pressed into the card slot 13. In this embodiment, the support plate 141 is rectangular, and the support springs 142 are provided at the four corners of the support plate 141 and are fixedly connected to the lower ground of the chassis 1. By compressing the support springs 142, multiple test tube plug plates 22 can be pressed between the card slot 13 and the support plate 141. When a test tube plug plate 22 with a test tube plug pressed is moved to the plugging station 12, the next test tube plug plate 22 without a test tube plug pressed will be pressed into the card slot 13, so as to realize the continuous filling of the test tube plug plates 22.

[0046] Furthermore, a handle 222 is provided on the test tube plug plate 22 to facilitate the movement of the test tube plug plate 22 in the card slot 13. It should be noted that the panel of the chassis 1 corresponding to the card slot 13 is open, that is, the handle 222 is exposed outside the chassis 1, and the test tube plug plate 22 can be moved to other positions more easily through the handle 222. Of course, the test tube plug plate 22 filled with test tube plugs can also be pulled out of the card slot 13 through the handle 222, and then the test tube plug is adjusted to a good position and then placed in the card slot 13 of the plugging station 12, which has a better effect.

[0047] See also Figure 1The plugging part 31 includes a pressure rod 311 and a pressure plate 312. The pressure rod 311 and the pressure plate 312 are arranged in the horizontal direction. The pressure rod 311 is located above the pressure plate 312, and the middle part of the pressure rod 311 and the center of the pressure plate 312 are connected by a connecting rod 313; a plurality of plugging protrusions 3121 corresponding to the test tube plug holes 221 are also provided below the pressure plate 312 to press the test tube plug into the test tube. When plugging, the test tube plug plate 22 is placed under the pressure plate 312, and the test tube plug is pressed into the test tube of the test tube rack 4 through the plugging protrusions 3121. The pressure rod 311 is made of hard metal, and the pressure plate 312 is made of hard metal or other pressure-resistant materials. The material of the plugging protrusion 3121 is the same as that of the pressure plate 312, and the size of the plugging protrusion 3121 is consistent with the size of the test tube plug hole 221.

[0048] Preferably, one end of the pressure rod 311 is rotatably connected to the chassis 1, and the other end of the pressure rod 311 is provided with a rubber sleeve for pressing, so as to facilitate manual plugging. The pressure rod 311 is pressed downward by the force of the arm, and the test tube plug is pressed into each test tube more effortlessly through the lever effect. Specifically, the chassis 1 is provided with a pressure rod connecting shaft 314, which is made of hard metal, and one end of the pressure rod 311 is rotatably connected to the pressure rod connecting shaft 314.

[0049] In addition, the pressing part 31 further includes a pressing rod spring 315, one end of which is connected to the middle of the pressing rod 311, and the other end is connected to the top of the chassis 1. The pressing rod spring 315 can reset the pressing plate 312 after the pressing is completed.

[0050] Preferably, a buffer pad 15 is further provided in the chassis 1. The buffer pad 15 is located at the plugging station 12 and is used to place the test tube rack 4 and adjust the height of the test tube rack 4. The buffer pad 15 can be a hard rubber pad or other material with a buffering function, and its function is to withstand the pressure when the test tube capping device is applied. Because the test tube rack 4 is generally made of plastic or thin metal, its bracket cannot withstand a large force, and a buffer pad 15 needs to be installed for protection. The height of the buffer pad 15 is adjustable. In order to adapt to test tubes of different heights.

[0051] In the technical solution of the present invention, the test tube plugs are filled into the test tube plug plate 22 by the test tube plug roller 21, and then the test tube plugs are pressed onto each test tube by the plug pressing part 31. Not only can a plurality of test tube plugs be installed at one time, thus improving efficiency, but also the physical strength of personnel is saved, and the plugging operation steps become very simple. Compared with the electric capping machine and the assembly line system, the equipment has a simple structure, low cost, simple and convenient operation, and can be widely promoted and popularized.
