Description

Technical Field

[0001] This invention relates to the field of test tube rack technology, and more specifically to a combined test tube rack that facilitates the pouring out of waste liquid and the disposal of test tubes. Background Technology

[0002] Medical test tubes are test tubes specifically designed for use in the medical field. They are typically made of sterile plastic materials to ensure sterility and safety during medical and diagnostic procedures. Medical test tubes are primarily used to collect, store, and analyze biological samples such as blood, urine, and saliva. They are widely used in medical institutions and play a vital role in disease diagnosis and treatment monitoring.

[0003] refer to Figure 9-10 As shown, in actual clinical testing, after medical staff collect blood, urine, saliva, etc. from patients using medical test tubes, they insert the test tubes into a test tube rack for temporary storage before testing the samples. After testing, not only the samples need to be discarded, but the test tubes also need to be disposed of. The current procedure is to first place the test tubes containing the collected samples on a regular test tube rack, then place the rack on a testing table for testing. After testing, the test tube rack is transferred to a storage box. Once the storage box is full, staff members first discard the samples and then dispose of the test tubes in a designated storage container. The current problem is that the samples and test tubes cannot be discarded in the same place; that is, the test tubes containing samples cannot be thrown away directly. Instead, the test tubes must be removed, the samples discarded, and then the used test tubes disposed of in a designated storage container. Because the samples need to be poured out one by one, and the samples are easily handled by medical staff during the process of pouring out and discarding the test tubes, which poses a risk, it reduces work efficiency and is not safe enough, causing inconvenience to the existing work of medical staff.

[0004] Therefore, designing a novel test tube rack that can handle liquid pouring or test tube disposal in a unified manner, thereby improving both efficiency and safety, remains an unsolved technical challenge in the current technology. Summary of the Invention

[0029] The technical solution provided by this invention has the following advantages:

[0030] 1. The combined test tube rack of the present invention includes a frame, a test tube rack, a lifting plate, a return spring, and a base plate; wherein the frame has an inner cavity and parallel opposing side walls, the inner walls of the two side walls are provided with guide slides, the outer walls are provided with handles, and the bottom ends of the two side walls are respectively provided with a first opening, a second opening, and a third opening communicating with the inner cavity, and the top ends of the second opening and the third opening are provided with blind holes; the test tube rack is provided with guide protrusions at both axial ends, the guide protrusions are adapted to be inserted into the guide slides, and can move under the guidance of the guide slides; the test tube rack is provided with a test tube cavity for installing test tubes, and the test tube cavity is provided with a handle near the bottom end. There is a limiting structure for limiting the test tube, and a bottom through hole is opened at the bottom end opposite to the test tube cavity; a lifting plate is installed at the bottom of the inner cavity of the frame, and a cylinder is fixed on the top surface, which can be inserted into the bottom through hole; a lifting part, a first reset part and a second reset part are respectively provided on both sides of the lifting plate. The lifting part extends a certain distance from the first opening, and the first reset part and the second reset part are installed into the second opening and the third opening; there are multiple reset springs, one end of which abuts against the top wall of the blind hole, and the other end abuts against the top surface of the first reset part or the second reset part; the base plate is fixedly set at the bottom of the frame and fixedly connected to the bottom of the side wall.

[0031] In the initial state, the reset spring pushes the first and second reset parts towards the base plate, keeping the lifting plate in contact with the base plate. During use, medical personnel insert test tubes containing samples into the test tube rack for temporary storage, place them on the testing table for testing, and after testing, move the test tube rack from the guide slide into the inner cavity of the frame. Once in position, the bottom through-hole of the test tube rack is aligned vertically with the cylinder of the lifting plate. When samples need to be poured out, the frame is flipped to pour the samples into the sample collection bin. When test tubes need to be pushed out of the test tube rack, the frame is flipped, and external force is used to press the lifting part in the direction of compressing the reset spring. The lifting part overcomes the spring force and moves, driving the cylinder to pass through the bottom through-hole, pushing the test tube out of the test tube cavity and thus pushing the test tubes into the test tube collection bin.

[0032] In other words, the combined test tube rack of the present invention allows for separate pouring of samples or disposal of test tubes, and also allows for unified pouring of samples or test tubes, which not only improves efficiency but also enhances safety.

[0033] 2. The combined test tube rack of the present invention has a limiting structure that can limit the test tubes so that they will not be poured out when a sample is poured out alone; when the test tubes are poured out, the lifting plate can push the test tubes to overcome the limiting effect of the limiting structure and push the test tubes out of the test tube rack; the limiting structure is an elastic protrusion, which undergoes slight deformation when a test tube is inserted, temporarily limiting and fixing the test tube inside the test tube rack.

[0034] 3. The combined test tube rack of the present invention also includes a switch door, one end of which is rotatably connected to a first protrusion block. The switch door can be opened or closed by rotation to allow the test tube rack to be loaded or unloaded. A fastener is fixedly disposed on the other end of the switch door. The fastener can engage with a slot. By engaging the fastener in the slot, the test tube rack installed inside the frame cavity can be squeezed and fixed. This not only prevents the test tube rack from slipping out, but also pushes the test tube rack to a position where the bottom through hole is vertically aligned with the cylinder, making it convenient to push out and tilt the test tubes using a lifting plate.

[0035] 4. The combined test tube rack of the present invention further includes a positioning plate installed inside the frame. The positioning plate has a plurality of positioning holes, which can guide the up and down movement of the cylinder, help the cylinder to accurately pass through the bottom through hole, and thus push the test tube out of the test tube rack.

[0036] 5. The combined test tube rack of the present invention has a second elongated through hole on the third side wall. When the test tube rack is taken out, it can be pushed through the second elongated through hole to move the test tube rack and help to take out the test tube rack. Attached Figure Description

[0052] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0053] This embodiment provides a combined test tube rack, such as Figure 1 , 5As shown in Figure 8, the device includes a frame 1, a test tube rack 2, a lifting plate 4, a return spring 5, and a base plate 115. The frame 1 has an inner cavity and two parallel, opposing side walls located on either side of the inner cavity. Each of the two side walls has at least one guide rail 11 on its inner wall and a handle 12 on its outer wall. The bottom ends of the two side walls each have a first opening 13, a second opening 14, and a third opening 15 communicating with the inner cavity. The top ends of the second opening 14 and the third opening 15 have blind holes. The test tube rack 2 has at least one guide protrusion fixed at each of its axial ends. Block 21, the guide protrusion 21 is adapted to be inserted into the guide slide 11 and can move under the guidance of the guide slide 11; the test tube rack 2 is provided with at least one test tube cavity 22 for installing test tubes, and the test tube cavity 22 is provided with a limiting structure 23 for limiting the test tube in the test tube cavity 22 near the bottom end; the bottom end of the test tube rack 2 is also provided with a bottom through hole 24 opposite to the test tube cavity 22; the lifting plate 4 is movably installed at the bottom of the inner cavity of the frame 1, and a plurality of cylinders 41 are fixedly provided on the top surface, the cylinders 41 being able to be inserted into the bottom through hole 24. 4; The lifting plate 4 is provided with lifting parts 42 on both sides, and a first reset part 43 and a second reset part 44 located on both sides of the lifting part 42. The lifting part 42 is adapted to extend outward a certain distance from the first opening 13, and the first reset part 43 and the second reset part 44 are adapted to be installed into the second opening 14 and the third opening 15; There are multiple reset springs 5, which are installed inside the blind hole, with one end abutting against the inner top wall of the blind hole and the other end abutting against the top surface of the first reset part 43 or the second reset part 44; The bottom plate 115 is fixedly installed at the bottom of the frame 1. The first reset part 43 and the second reset part 44 are fixedly connected to the bottom of the side wall. In the initial state, the reset spring 5 pushes the first reset part 43 and the second reset part 44 towards the bottom plate 115, so that the lifting plate 4 keeps in contact with the bottom plate 115. When it is necessary to push the test tube out of the test tube cavity 22, the frame 1 is flipped over, and the lifting part 42 is pressed in the direction of compressing the reset spring 5 with external force. The lifting part 42 moves after overcoming the elastic force of the reset spring 5, driving the cylinder 41 to pass through the bottom through hole 24 and push the test tube out of the test tube cavity 22.

[0054] In the initial state, the reset spring 5 pushes the first reset part 43 and the second reset part 44 towards the base plate 115, so that the lifting plate 4 keeps in contact with the base plate 115. In use, medical staff insert test tubes containing samples into the test tube rack 2 for temporary storage and place them on the testing table for testing. After the test is completed, the test tube rack 2 containing test tubes is moved from the guide slide 11 to the inner cavity of the frame 1. After it is moved into place, the bottom through hole 24 of the test tube rack 2 is exactly vertically aligned with the cylinder 41 of the lifting plate 4. When it is necessary to pour out the sample, the frame 1 is flipped to pour the sample into the sample recycling bin. When it is necessary to push the test tube out of the test tube rack 2, the frame 1 is flipped and the lifting part 42 is pressed in the direction of compressing the reset spring 5 with external force. The lifting part 42 moves after overcoming the elastic force of the reset spring 5, driving the cylinder 41 to pass through the bottom through hole 24 and push the test tube out of the test tube cavity 22, thereby pushing the test tube into the test tube recycling bin.

[0065] The combined test tube rack in this embodiment is used as follows: During routine testing, medical staff collect blood, urine, saliva, etc., from patients using medical test tubes. The test tubes containing the samples are then inserted into the test tube rack 2 for temporary storage and placed on the testing table for analysis. After the analysis is completed, the switch door 6 is opened, and the test tube rack 2 containing the test tubes is moved from the guide slide 11 into the inner cavity of the frame 1. After the test tube rack 2 is properly positioned, the switch door 6 is closed. The switch door 6 then clamps and secures the test tube rack 2, ensuring its stability. The bottom through hole 24 is vertically aligned with the positioning hole 101 and cylinder 41 on the positioning plate 10. When it is necessary to pour the sample, the frame 1 is flipped to pour the sample into the sample recycling bin. When it is necessary to push the test tube out of the test tube rack 2, the frame 1 is flipped and the lifting part 42 is pressed in the direction of the compression return spring 5 with external force. The lifting part 42 moves after overcoming the elastic force of the return spring 5, driving the cylinder 41 to pass through the bottom through hole 24 and push the test tube out of the test tube cavity 22, thereby pushing the test tube into the test tube recycling bin.
