Description

Technical Field

[0001] This utility model relates to the field of in vitro diagnostic medical device technology, and in particular to a test tube sample injection device. Background Technology

[0002] With the development of technology, instruments in the field of in vitro diagnostics for medical devices, such as specific protein analyzers, coagulation analyzers, and biochemical analyzers, are all moving towards automation and intelligence. Medical staff only need to place the collected urine, blood, and other bodily fluid samples into the corresponding test tube racks, which are then automatically transported to the appropriate positions for testing. During this transport process, it is often necessary to perform presence / absence checks and precise positioning of the test tubes. However, the shape and structure of the test tubes used to hold samples vary between different hospitals, and even within the same hospital, multiple types of test tubes may be used.

[0003] Furthermore, different types of bodily fluids, such as urine and blood, require the same or similar tests. However, due to limitations in instrument functionality, these tests often have to be performed on different instruments. Hospital laboratories, often with limited space, tend to house more instruments, making the internal environment extremely crowded and hindering the normal operations of medical staff, thus affecting sample processing efficiency. More equipment also increases the hospital's equipment purchase and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a test tube injection device, which aims to solve the problem that existing instruments have limited functionality and that different types of body fluids can only be detected on different instruments.

[0005] To achieve the above objectives, this utility model provides a test tube injection device, including a test tube clamping component, a translational drive component, a test tube holding component, a test tube presence / absence detection component, and a test tube positioning component. The test tube holding component is disposed on one side of the translational drive component, the test tube clamping component is disposed on one side of the test tube holding component, the test tube presence / absence detection component is disposed on one side of the translational drive component, and the test tube positioning component is disposed on one side of the test tube presence / absence detection component. The test tube holding component includes a test tube base, a test tube holder, and a test tube type detection sensor. The test tube base is fixedly disposed on one side of the translational drive component, and the test tube holder is detachably connected to the test tube base and located on the top of the test tube base. The test tube type detection sensor is fixedly connected to the test tube base and located on one side of the test tube base.

[0006] The test tube holder further includes a limiting plate, which is fixedly connected to the test tube base and located on one side of the test tube base. The limiting plate has a limiting check part located on the side of the limiting plate near the test tube base. The test tube base has a test tube position located on one side of the test tube base.

[0007] The test tube presence / absence detection component includes a base plate, a slotted optical coupler, a detection rotating plate, a torsion spring, a detection sensing plate, and a rotating shaft. The base plate is disposed on one side of the test tube positioning component. The slotted optical coupler is fixedly connected to the base plate and located on one side of the base plate. The rotating shaft is fixedly connected to the base plate and located on one side of the base plate. The detection rotating plate is rotatably connected to the rotating shaft and located on one side of the rotating shaft. The torsion spring is sleeved on one side of the rotating shaft. The detection sensing plate is fixedly connected to the detection rotating plate and located at the bottom of the detection rotating plate.

[0008] The test tube positioning component includes a first positioning claw and a second positioning claw, which are respectively disposed on one side of the detection rotating plate. Both the first positioning claw and the second positioning claw have limiting grooves.

[0009] The translation drive component is a structure consisting of a motor and a guide rail synchronous belt.

[0010] This utility model discloses a test tube injection device. The test tube clamping component, a prior art technology, is used to clamp test tubes from an external test tube rack, raise the test tubes for subsequent test tube type detection, and place them on a test tube holder. After sample collection, the clamping component clamps the test tubes again and returns them to their original position on the test tube rack. When the test tubes are conveyed to the instrument's injection position, the clamping component picks them up and raises them to the same height as the test tube holder. A test tube type detection sensor located at the front end of the test tube holder detects and identifies the test tube type. After identification, the clamping component continues to rise a certain height, and then a translational drive drives the test tube holder, positioning the corresponding test tube holder directly below the test tube. Next, the clamping component places the test tube on the test tube holder, and the translational drive retracts, thereby translating the external test tubes to a designated position inside the instrument. After being moved to the designated position, the presence or absence of a test tube is simultaneously detected to determine whether a test tube is present on the test tube holder. When a test tube is present, the test tube positioning device clamps the test tube for subsequent sampling to collect the body fluid sample from the test tube. This test tube injection device can detect the presence or absence of a test tube and monitor the test tube holder in real time to ensure the instrument can proceed to the next step. When a test tube is present, the test tube positioning device clamps the test tube for precise positioning, ensuring the instrument's subsequent sample collection operation. The test tube holder on the test tube holder is designed for quick assembly and disassembly. When switching between different sample types, simply attach the corresponding test tube holder to the test tube holder base. This allows the instrument to be used for different types of body fluids such as urine and blood, resulting in high instrument compatibility and significantly improving the efficiency of hospital space, instrument purchase costs, and personnel. The test tube type detection sensor is used to detect and identify the test tube type, solving the problem of limited functionality in existing instruments, where different types of body fluids can only be tested on different instruments.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 8This utility model provides a test tube injection device, including a test tube clamping component 1, a translation drive component 2, a test tube holding component 3, a test tube presence / absence detection component 4, and a test tube positioning component 5. The test tube holding component 3 is disposed on one side of the translation drive component 2, the test tube clamping component 1 is disposed on one side of the test tube holding component 3, the test tube presence / absence detection component 4 is disposed on one side of the translation drive component 2, and the test tube positioning component 5 is disposed on one side of the test tube presence / absence detection component 4. The test tube holding component 3 includes a test tube base 31, a test tube holder 32, and a test tube type detection sensor 33. The test tube base 31 is fixedly disposed on one side of the translation drive component 2, the test tube holder 32 is detachably connected to the test tube base 31 and is located on the top of the test tube base 31, and the test tube type detection sensor 33 is fixedly connected to the test tube base 31 and is located on one side of the test tube base 31.

[0023] In this embodiment of the invention, the test tube clamp 1 is a prior art device used to clamp test tubes from the external test tube rack of the instrument, raise the test tubes for subsequent test tube type detection, and place the test tubes on the test tube holder 3. After the test tubes are conveyed to the sample injection position of the instrument, the test tube clamp 1 picks up the test tubes and raises them to the same height as the test tube holder 3. The test tube type detection sensor 33, located at the front end of the test tube holder 3, detects and identifies the test tube type. After identification, the test tube clamp 1 continues to rise a certain height, and then the translation drive 2 drives the test tube holder 3 so that the corresponding test tube seat 32 on the test tube holder 3 is directly below the test tube. Next, the test tube clamp 1 places the test tube on the test tube seat 32, and the translation drive 2 retracts, thereby translating the external test tubes to a designated position inside the instrument. After being moved to the designated position, the presence or absence detection element 4 simultaneously detects whether a test tube is present on the test tube holder 32. When a test tube is present, the test tube positioning element 5 clamps the test tube for subsequent sampling to collect body fluid samples from the inside of the test tube. This test tube injection device can detect the presence or absence of test tubes and monitor the test tube holder 32 in real time to ensure the instrument can proceed to the next step. When a test tube is present, the test tube positioning element 5 clamps the test tube to achieve precise positioning and ensure the instrument's subsequent sample collection operation. The test tube type detection sensor 33 is used to detect and identify the test tube type. Specifically, when the test tube clamping element 1 clamps the test tube and places it in front of the test tube holder 32, i.e. Figure 4In the indicated state, the test tube type detection sensor 33 operates to determine the type of test tube. Because some test tubes have an inner cavity that extends to the bottom, allowing the sample to fill the entire tube; while others have an inner cavity that only extends to the middle, allowing the sample to only reach the middle position vertically, the test tube type detection sensor 33 determines the test tube type by detecting whether there is liquid in the lower half of the test tube. When the instrument tests urine samples, because urine sample tubes and blood sample tubes differ significantly in size and structure, they often cannot be placed in the same test tube holder 32. In this case, the test tube holder 32 for blood samples can be replaced with the test tube holder 32 for urine samples, such as... Figure 5 As shown. This design allows the same instrument to be compatible with the testing of different types of samples, bringing great convenience and benefits to hospital laboratories. The test tube holder 32 on the test tube container 3 is designed for quick assembly and disassembly. When switching between different types of samples, simply snap the corresponding test tube holder 32 onto the test tube holder base 31. This allows the instrument to be used for different types of bodily fluids such as urine and blood. The instrument has high compatibility, significantly improving the efficiency of hospital space, instrument purchase costs, and personnel efficiency. It solves the problem of limited functionality in existing instruments, where different types of bodily fluids can only be tested on different instruments.

[0024] Furthermore, the test tube holder 3 also includes a limiting plate 311, which is fixedly connected to the test tube base 31 and located on one side of the test tube base 31. The limiting plate 311 has a limiting check part 3111, which is located on the side of the limiting plate 311 closer to the test tube holder 32. The test tube holder 32 has a test tube position 312, which is located on one side of the test tube holder 32.

[0025] In this embodiment of the invention, limiting plates 311 are provided on the left and right sides of the test tube holder base 31, and a limiting check part 3111 is provided at the upper end of the limiting plate 311 to restrict the vertical movement of the test tube holder 32. When the operator presses the limiting plate 311 with his hand, he can pull the test tube holder 32 upwards and quickly remove it. The test tube holder 32 is provided with multiple test tube positions 312, which can accommodate test tubes of different shapes and structures, increasing the instrument's compatibility with test tubes and meeting the needs of different hospital departments.

[0026] Furthermore, the test tube presence / absence detection component 4 includes a base plate 41, a slotted optical coupler 42, a detection rotating plate 43, a torsion spring 44, a detection sensing plate 45, and a rotating shaft 46. The base plate 41 is disposed on one side of the test tube positioning component 5. The slotted optical coupler 42 is fixedly connected to the base plate 41 and located on one side of the base plate 41. The rotating shaft 46 is fixedly connected to the base plate 41 and located on one side of the base plate 41. The detection rotating plate 43 is rotatably connected to the rotating shaft 46 and located on one side of the rotating shaft 46. The torsion spring 44 is sleeved on one side of the rotating shaft 46. The detection sensing plate 45 is fixedly connected to the detection rotating plate 43 and located at the bottom of the detection rotating plate 43.

[0027] In this embodiment of the invention, the slotted optocoupler 42, the rotating shaft 46, etc., are all fixedly mounted on the base plate 41. The rotating shaft 46 is fitted with the detection rotating plate 43 and the torsion spring 44. The detection sensing plate 45 is fixedly mounted on the detection rotating plate 43. When the test tube container 3 moves backward into the instrument along with the translational drive 2, reaching the position of the test tube presence / absence detection element 4, the detection sensing plate 45 is rotated backward by the test tube, and thus rotates into the slot of the slotted optocoupler 42, thereby detecting that a test tube is placed on the test tube position 312. Figure 7 As shown, this is the state where the instrument detects the presence of a test tube when it is placed on the test tube position 312. This design can detect whether a test tube is present on the test tube position 312 of the test tube holder 32. When a test tube is present, the instrument's sampling mechanism will move to directly above the corresponding test tube to collect the sample, depending on the type of test tube.

[0028] Furthermore, the test tube positioning component 5 includes a first positioning claw 51 and a second positioning claw 52. The first positioning claw 51 and the second positioning claw 52 are respectively disposed on one side of the detection rotating plate 43. Both the first positioning claw 51 and the second positioning claw 52 have a limiting groove 511.

[0029] In this embodiment of the utility model, the first positioning claw 51 and the second positioning claw 52 are respectively fixed on the upper and lower sections of the belt and move in opposite directions to realize the clamping and loosening of the test tube. The limiting groove 511 is multiple, which realizes the clamping and positioning operation of the first positioning claw 51 and the second positioning claw 52.

[0030] Furthermore, the translation drive 2 is a structure consisting of a motor and a guide rail synchronous belt.

[0031] In this embodiment of the utility model, the translation drive 2 adopts the existing technology of motor combined with guide rail synchronous belt structure, and its main function is to drive the test tube container 3 to move horizontally back and forth.

[0032] The above-disclosed embodiments are merely preferred embodiments of the test tube injection device of this utility model, and should not be construed as limiting the scope of the utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this utility model are still within the scope of the utility model.
