Description

Technical Field

[0001] The present invention relates to the technical field of in vitro diagnostic medical devices, and in particular to a test tube sampling device. Background Art

[0002] With the development of science and technology, specific protein analyzers, coagulation analyzers, biochemical analyzers and other instruments in the field of in vitro diagnostics of medical devices are developing towards automation and intelligence. Medical staff only need to put the collected urine, blood and other body fluid samples into the corresponding test tube rack, and the test tube rack is automatically transferred to the corresponding position on the instrument for testing. In this transmission process, it is often necessary to detect the presence or absence of test tubes, accurately locate them, etc. However, the appearance and structure of the test tubes holding samples will vary from hospital to hospital, and even the same hospital may use multiple test tubes.

[0003] In addition, different types of body fluids such as urine and blood will undergo the same or similar testing items. However, due to the limited functions of the instruments, the tests can only be completed on different instruments. However, due to the limited space in the hospital's laboratory department, more instruments are placed, which makes the internal environment of the laboratory department particularly crowded, and even affects the normal operation of medical staff and the efficiency of sample processing. More instruments and equipment also cause greater equipment purchase and maintenance costs for the hospital. Summary of the invention

[0004] The object of the present invention is to provide a test tube sampling device, aiming to solve the problem that the existing instruments are limited in function and different types of body fluids can only be tested on different instruments.

[0005] To achieve the above-mentioned objectives, the present invention provides a test tube sampling device, comprising a test tube clamping member, a translation driving member, a test tube holding member, a test tube presence detection member and a test tube positioning member, the test tube holding member is arranged on one side of the translation driving member, the test tube clamping member is arranged on one side of the test tube holding member, the test tube presence detection member is arranged on one side of the translation driving member, the test tube positioning member is arranged on one side of the test tube presence detection member, the test tube holding member comprises a test tube holder base, a test tube holder and a test tube type detection sensor; the test tube holder base is fixedly arranged on one side of the translation driving member, the test tube holder is detachably connected to the test tube holder base and is located on the top of the test tube holder base, and the test tube type detection sensor is fixedly connected to the test tube holder base and is located on one side of the test tube holder base.

[0006] Among them, the test tube holding member also includes a limit plate, the limit plate is fixedly connected to the test tube holder base and is located on one side of the test tube holder base, the limit plate has a limit check portion, the limit check portion is located on the side of the limit plate close to the test tube holder, the test tube holder has a test tube position, and the test tube position is located on one side of the test tube holder.

[0007] Among them, the test tube presence detection component includes a base plate, a slot-type optical coupler, a detection rotating plate, a torsion spring, a detection sensing plate and a rotating shaft, the base plate is arranged on one side of the test tube positioning component, the slot-type optical coupler is fixedly connected to the base plate and is located on one side of the base plate, the rotating shaft is fixedly connected to the base plate and is located on one side of the base plate, the detection rotating plate is rotatably connected to the rotating shaft and is located on one side of the rotating shaft, the torsion spring is sleeved on one side of the rotating shaft, and the detection sensing plate is fixedly connected to the detection rotating plate and is located at the bottom of the detection rotating plate.

[0008] Wherein, the test tube positioning member includes a first positioning jaw and a second positioning jaw, the first positioning jaw and the second positioning jaw are respectively arranged on one side of the detection rotating plate, and the first positioning jaw and the second positioning jaw both have a limiting groove.

[0009] Wherein, the translation drive component is a motor with a guide rail synchronous belt structure.

[0010] A test tube sampling device of the present invention, the test tube clamping part is a prior art, which is used to clamp the test tube on the test tube rack outside the instrument, lift the test tube for subsequent test tube type detection, and place the test tube on the test tube holding part. After completing sample collection, the test tube clamping part clamps the test tube again and puts it back to the original position of the test tube rack. When the test tube is transmitted to the instrument sampling position, the test tube clamping part clamps the test tube and rises to the same height as the test tube holding part. The test tube type detection sensor arranged at the front end of the test tube holding part detects and identifies the test tube type. After the identification is completed, the test tube clamping part continues to rise to a certain height, and then the translation drive part drives the test tube holding part so that the corresponding test tube seat on the test tube holding part is directly below the test tube. Then, the test tube clamping part places the test tube on the test tube seat, and the translation drive part retracts backward, thereby realizing the translation of the test tube outside the instrument to the specified position inside the instrument. After being translated to the designated position, the test tube presence detection member is simultaneously detected to determine whether there is a test tube on the test tube holder. When there is a test tube, the test tube positioning member clamps the test tube so that the subsequent sampling mechanism can collect the body fluid sample inside the test tube. The test tube sampling device can detect the presence of the test tube and monitor in real time whether there is a test tube in the test tube holder so that the instrument can execute the next process. In the case of a test tube, the test tube positioning member clamps the test tube to achieve precise positioning to ensure the subsequent sample collection operation of the instrument. The test tube holder on the test tube holding member is set to a form that can be quickly disassembled and assembled. When it is necessary to switch between different types of samples, only the corresponding test tube holder needs to be buckled onto the test tube holder base, so that the instrument can switch between different types of body fluids such as urine and blood. The instrument has high compatibility and can significantly improve the space environment benefits of the hospital, the cost-effectiveness of instrument purchase, and the personnel benefits. The test tube type detection sensor is used for detection and identification of the test tube type, which solves the problem that the existing instrument is limited in function and different types of body fluids can only be detected on different instruments.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] See also Figures 1 to 8 The present invention provides a test tube sampling device, comprising a test tube clamping member 1, a translation driving member 2, a test tube holding member 3, a test tube presence detection member 4 and a test tube positioning member 5, wherein the test tube holding member 3 is arranged on one side of the translation driving member 2, the test tube clamping member 1 is arranged on one side of the test tube holding member 3, the test tube presence detection member 4 is arranged on one side of the translation driving member 2, the test tube positioning member 5 is arranged on one side of the test tube presence detection member 4, the test tube holding member 3 comprises a test tube holder base 31, a test tube holder 32 and a test tube type detection sensor 33; the test tube holder base 31 is fixedly arranged on one side of the translation driving member 2, the test tube holder 32 is detachably connected to the test tube holder base 31 and is located on the top of the test tube holder base 31, and the test tube type detection sensor 33 is fixedly connected to the test tube holder base 31 and is located on one side of the test tube holder base 31.

[0023] In the embodiment of the present invention, the test tube clamping member 1 is a prior art, which is used to clamp the test tube on the test tube rack outside the instrument, lift the test tube for subsequent test tube type detection, and place the test tube on the test tube holding member 3. When the test tube is transferred to the instrument sampling position, the test tube clamping member 1 clamps the test tube, rises to the same height as the test tube holding member 3, and the test tube type detection sensor 33 arranged at the front end of the test tube holding member 3 detects and identifies the test tube type. After the identification is completed, the test tube clamping member 1 continues to rise to a certain height, and then the translation drive member 2 drives the test tube holding member 3, so that the corresponding test tube seat 32 on the test tube holding member 3 is directly below the test tube. Then, the test tube clamping member 1 places the test tube on the test tube seat 32, and the translation drive member 2 retracts backward, thereby realizing the translation of the test tube outside the instrument to the specified position inside the instrument. After translating to the designated position, the test tube presence detection member 4 simultaneously detects whether there is a test tube on the test tube holder 32. When a test tube exists, the test tube positioning member 5 clamps the test tube so that the subsequent sampling mechanism can collect the body fluid sample inside the test tube. The test tube sampling device can detect the presence of the test tube and monitor in real time whether there is a test tube in the test tube holder 32 so that the next step of the instrument can be executed. When there is a test tube, the test tube positioning member 5 clamps the test tube to achieve precise positioning to ensure the subsequent sample collection operation of the instrument. The test tube type detection sensor 33 is used to detect and identify the test tube type. Specifically, when the test tube clamping member 1 clamps the test tube and puts it in front of the test tube holder 32, that is, Figure 4 In the state shown, the test tube type detection sensor 33 works to determine the type of test tube. Because the inner cavities of some test tubes extend deep to the bottom, the sample can fill the entire test tube; while the inner cavities of some test tubes only extend to the middle of the test tube, the sample can only reach the middle position in the vertical direction of the test tube. The test tube type detection sensor 33 detects whether there is liquid in the lower half of the test tube to complete the test of the test tube type. When the instrument detects urine samples, due to the large differences in size and structure between urine sample test tubes and blood sample test tubes, they often cannot be placed in the same test tube holder 32. At this time, the test tube holder 32 for blood samples can be replaced with the test tube holder 32 for urine samples. Figure 5As shown. Through such a design, the same instrument can be compatible with the detection of different types of samples, which brings great convenience and benefits to the hospital's laboratory department. The test tube holder 32 on the test tube holder 3 is set to be quickly disassembled and assembled. When it is necessary to switch between different types of samples, it is only necessary to buckle the corresponding test tube holder 32 onto the test tube holder base 31, so that the instrument can be switched between different types of body fluids such as urine and blood. The instrument has high compatibility, which can significantly improve the hospital's space environment benefits, instrument purchase cost benefits, personnel benefits, etc., and solve the problem that the existing instrument is limited in function and different types of body fluids can only be tested on different instruments.

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

[0025] In the embodiment of the present invention, the limit plates 311 are provided on the left and right sides of the test tube holder base 31, and the limit check portion 3111 is provided on the upper end of the limit plate 311, which is used to limit the upward and downward movement of the test tube holder 32. When the operator presses the limit plate 311 by hand and pulls the test tube holder 32 upward at the same time, the test tube holder 32 can be quickly taken out. The test tube holder 32 is provided with a plurality of test tube positions 312, which can be compatible with test tubes of different shapes and structures, and can increase the compatibility of the instrument itself with test tubes to meet the needs of different hospital departments.

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

[0027] In the embodiment of the present invention, the slot-type optical coupler 42, the rotating shaft 46, etc. are all fixedly arranged on the bottom plate 41. The rotating shaft 46 is provided with the detection rotating plate 43 and the torsion spring 44. The detection sensing plate 45 is fixedly arranged on the detection rotating plate 43. When the test tube holding member 3 moves backward into the instrument along with the translation driving member 2 and reaches the position of the test tube presence detection member 4, the detection sensing plate 45 is rotated backward by the test tube, and the detection sensing plate 45 rotates accordingly and enters the slot of the slot-type optical coupler 42, thereby detecting that a test tube is placed on the test tube position 312. Figure 7 As shown, when a test tube is placed on the test tube position 312, the instrument detects the presence of a test tube. This design can detect whether there is a test tube on the test tube position 312 of the test tube holder 32. When there is a test tube, the instrument sampling mechanism will move to the top of the corresponding test tube for sample collection according to the type of the test tube.

[0028] Furthermore, the test tube positioning member 5 includes a first positioning jaw 51 and a second positioning jaw 52 , and the first positioning jaw 51 and the second positioning jaw 52 are respectively arranged on one side of the detection rotating plate 43 , and the first positioning jaw 51 and the second positioning jaw 52 both have a limiting groove 511 .

[0029] In the embodiment of the present invention, the first positioning jaw 51 and the second positioning jaw 52 are respectively fixed on the upper and lower sections of the belt to make relative reverse movements, thereby realizing the clamping and loosening of the test tube. There are multiple limiting grooves 511 to realize the clamping and positioning operations of the first positioning jaw 51 and the second positioning jaw 52.

[0030] Furthermore, the translation drive component 2 is a motor with a guide rail synchronous belt structure.

[0031] In the embodiment of the present invention, the translation driving member 2 adopts the existing technology of a motor combined with a guide rail synchronous belt structure, and its main function is to drive the test tube holding member 3 to move horizontally back and forth.

[0032] The above disclosure is only a preferred embodiment of a test tube sampling device of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
