Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an analyzer. Background Art

[0002] At present, the front shell of IVD instruments mainly has two solutions: with display screen and without display screen. For those without display screen, external monitor and computer host are generally used. The disadvantage of this method is that there are many random accessories, which generally need to be equipped with a monitor and computer or the user end. This leads to an increase in the cost of random accessories.

[0003] The other is that the instrument itself comes with a display screen, which is generally mounted and fixed on the front shell. This solution is divided into two types. One is that the display screen and the front shell assembly are mounted and fixed on the frame and cannot be flipped open. The other is connected to the frame through hinges, springs and other mechanisms. During use, such as when replacing reagents, the front shell assembly can be flipped up and opened, or the front shell assembly is not opened, and a flip cover is added at a specific position of the front shell assembly to replace the reagent. The first method is limited in that the reagent or test cup cannot be replaced by opening the front shell. The disadvantage of the second method is that when the front shell assembly is large, the flip cover is heavy and inconvenient to operate, and the display screen cannot be seen by the human eye after flipping the cover. The method of adding a flip cover at a specific position will affect the aesthetics of the entire machine. Summary of the invention

[0030] The present invention provides an analyzer.

[0031] Reference Figures 1 to 2In one embodiment of the present invention, the analyzer includes: an analyzer body 1, a front shell base 2 and a sliding front shell 3; a working chamber 11 is provided in the analyzer body 1; the front shell base 2 is installed on the analyzer body 1, and the front shell base 2 is provided with a connecting port 21, and the connecting port 21 is connected to the working chamber 11; the sliding front shell 3 is provided with a display module 4, and the sliding front shell 3 is slidably connected to the front shell base 2 to slide and open and close the connecting port 21.

[0032] The technical solution of the present invention is to slide and open the communication port 21 by slidingly connecting the sliding front shell 3 with the front shell base 2. Specifically, the analyzer body 1 is provided with a working chamber 11, and the front shell base 2 is installed at the front end of the analyzer body 1. As a base for the sliding front shell 3 to slide, the front shell base 2 is provided with a communication port 21, which is connected to the working chamber 11 in the analyzer body 1. Through the communication port 21, while the working condition of the instrument in the working chamber 11 can be observed, reagents can also be placed into the working chamber 11 or taken out from the working chamber 11. Since the present application adopts a sliding front shell 3 that slides and opens and closes at the communication port 21, and the display module 4 has a display screen exposed at the front end of the sliding front shell 3, when the communication port 21 is slid open, the use of the display screen set on the sliding front shell 3 will not be affected, that is, the display screen can be observed or operated when the sliding front shell 3 is opened to add reagents.

[0033] Specifically, when the sliding front shell 3 slides downward to the lowest position, the connecting port 21 is covered by the sliding front shell 3, the working chamber 11 in the analyzer body 1 is completely sealed, and the analyzer can perform analysis and detection; when the sliding front shell 3 slides upward to the highest position, the connecting port 21 is completely exposed to the outside, and the working chamber 11 in the analyzer body 1 is connected with the space outside the analyzer through the connecting port 21, and at this time, reagents can be placed in the working chamber 11 through the connecting port 21 or reagents can be taken out from the working chamber 11 through the connecting port 21.

[0034] Further, the analyzer further includes a guide assembly 5, the guide assembly 5 is arranged on the front shell base 2, and the sliding front shell 3 is slidably connected with the front shell base 2 through the guide assembly 5. Specifically, the guide assembly 5 is arranged on the front shell base 2. Since the front shell base 2 is connected to the analyzer body 1, the corresponding front shell base 2 has a high stability, so in order to improve the stability of the guide assembly 5 after installation, the guide assembly 5 is arranged on the front shell base 2. It should be noted that the number of guide assemblies 5 is not limited. One guide assembly 5 can be arranged to save costs, or two or more guide assemblies 5 can be arranged to further improve the sliding stability of the sliding front shell 3. Specifically, in this embodiment, guide assemblies 5 are respectively arranged on opposite sides of the front shell base 2. On the one hand, the guide assemblies 5 are arranged on the opposite sides to disperse the gravity of the sliding front shell 3 to reduce the burden of each guide assembly 5, and on the other hand, the sliding front shell 3 is smoother and more stable when sliding. It can be understood that the more guide assemblies 5 there are, the more stable the sliding front shell 3 is when sliding.

[0035] In one embodiment, reference Figure 3 and Figure 4 , the guide assembly 5 includes a first fixed portion 51, a second fixed portion 52, a slider 53, and a guide rail 54; the first fixed portion 51 is fixedly installed on the front shell base 2, the guide rail 54 is arranged on the first fixed portion 51, the second fixed portion 52 is fixedly installed on the sliding front shell 3, the slider 53 is arranged on the second fixed portion 52, and the slider 53 is slidably arranged on the guide rail 54. The sliding mode of the slider 53 and the slide rail has a fixed sliding direction and a stable sliding process. In this embodiment, the guide rail 54 of the guide assembly 5 extends along the height direction of the analyzer. However, the present design is not limited to this. In other embodiments, the guide rail 54 of the guide assembly 5 can also be a lateral sliding door opening along the analyzer, or a horizontal door opening in the direction away from the working chamber 11.

[0036] Furthermore, in one embodiment, the front housing base 2 is provided with a detection device 6, and the detection device 6 is used to detect the specific position of the sliding front housing 3. Specifically, in this embodiment, reference Figure 2 and Figure 3, the detection device 6 is arranged on the guide assembly on the opposite sides of the front shell base 2. The detection device 6 includes a photoelectric sensor 61 and a light shielding sheet 62. The guide assembly 5 is provided with a photoelectric sensor 61 and a light shielding sheet 62. The photoelectric sensor 61 is electrically connected to the display module 4; the photoelectric sensor 61 is arranged on the first fixing part 51, but the present design is not limited to the bottom or top of the slide rail. If the photoelectric sensor 61 is arranged at the bottom of the slide rail, the photoelectric sensor 61 can detect the closed state of the sliding front shell 3; if the photoelectric sensor 61 is arranged at the top of the slide rail, the photoelectric sensor 61 can detect the open state of the sliding front shell 3; if the photoelectric sensor 61 is arranged at both the bottom and the top of the slide rail, the photoelectric sensor 61 can detect both the closed state and the open state of the sliding front shell 3. The light shielding sheet 62 is arranged on the slider 53; the display module 4 obtains the opening and closing information of the sliding front shell 3 with respect to the front shell base 2 through the photoelectric sensor 61. Specifically, the photoelectric sensor 61 in this embodiment is triggered by the light blocking sheet 62. When the light blocking sheet 62 is driven by the slider 53 and moves to the position of the photoelectric sensor 61, after the light blocking sheet 62 covers the photoelectric sensor 61, the signal in the photoelectric sensor 61 changes, and the photoelectric sensor 61 will send a signal to the display module 4, so that the display screen on the display module 4 can display the specific position of the sliding front shell 3.

[0037] However, the detection device 6 in the present design is not limited to the photoelectric sensor 61 and the light shielding film 62. In other embodiments, the detection device 6 can also be a Hall sensor, a capacitive sensor, etc.

[0038] Furthermore, in one embodiment, the friction pre-tightening component 7 is disposed at a position where the sliding front shell 3 is always connected to the front shell base 2. Specifically, the friction pre-tightening component 7 is disposed on the guide component 5, and the friction pre-tightening component 7 is disposed between the slider 53 and the first fixed portion 51. The slider 53 has the ability to maintain its position by frictionally pre-tightening the first fixed portion 51 with the friction pre-tightening component 7. However, the present design is not limited to this. In other embodiments, the friction pre-tightening component 7 is disposed on the side of the front shell base 2 facing the sliding front shell 3, and one end of the friction pre-tightening component 7 is fixed to the front shell base 2, and the other end is slidably and frictionally connected to the sliding front shell 3; or, one end of the friction pre-tightening component 7 is fixed to the sliding front shell 3, and the other end is slidably and frictionally connected to the front shell base 2.

[0039] Furthermore, in this embodiment, reference Figure 4The friction preload assembly 7 includes a mounting bracket 71, a preload spring 72 and a friction member 73; the mounting bracket 71 is mounted on the slider 53, and the mounting bracket 71 is provided with a preload groove 74, the notch of which is opened toward the first fixing portion 51; the friction member 73 is arranged in the preload groove 74, and the end face of the friction member 73 away from the bottom of the preload groove 74 abuts against the surface of the first fixing portion 51; one end of the preload spring 72 is arranged at the bottom of the preload groove 74, and the other end is connected to the friction member 73. It should be understood that in this embodiment, the preload groove 74 is a through groove, but the through groove includes a first through groove close to the first fixing portion 51 and a second through groove away from the first fixing portion 51, the diameter of the first through groove is larger than the diameter of the second through groove, and the preload spring 72 is mounted in the first through groove, so the above-mentioned groove bottom is a step surface formed between the first through groove and the second through groove. In other embodiments, the preload groove 74 is a non-through groove, and the notch of the preload groove 74 needs to always face the first fixed part 51, so that the friction member 73 can contact the surface of the first fixed part 51 under the pressure of the preload spring 72. It should be noted that the material selection of the friction member 73 needs to generate friction when it moves relative to the surface of the first fixed part 51. Specifically, the material of the first fixed part 51 is stainless steel or aluminum alloy, and the material of the friction member 73 can be rubber or resin fiber material. All materials that can generate friction with the surface of the first fixed part 51 are within the scope of protection of this design.

[0040] Furthermore, the analyzer further includes an elastic balance component 8, which is connected to the front shell base 2 and the sliding front shell 3; the elastic balance component 8 provides an upward elastic force, which is balanced with the gravity of the sliding front shell 3, so that the sliding front shell 3 can hover within the sliding range. Under the action of the elastic balance component 8, the sliding front shell 3 can hover at any position. In this embodiment, the sliding front shell 3 can hover at any height. In this way, after moving the sliding front shell 3 upward, the sliding front shell 3 can automatically maintain its position, avoiding the need for people to manually support the sliding front shell 3, which provides great convenience for people to operate the analyzer.

[0041] Furthermore, refer to Figure 5The elastic balancing component 8 includes an elastic member and a fixed bracket 81, the fixed bracket 81 is arranged on the front shell base 2, the fixed end 821 of the elastic member is connected to the fixed bracket 81, and the movable end 822 of the elastic member is fixedly connected to the sliding front shell 3. Specifically, the elastic member is a spring 82, and the spring 82 includes a fixed end 821 arranged on the fixed bracket 81, and a movable end 822 arranged on the sliding front shell 3. However, the present design is not limited to this. In other embodiments, the elastic member can also be a spring, one end of the spring is fixed to the sliding front shell 3, and the other end of the spring is fixed to the front shell base 2, and the gravity of the sliding front shell 3 is balanced by the elastic force of the spring.

[0042] It should be understood that, in one embodiment, under the action of the spring balance assembly, the sliding front shell 3 can be kept roughly suspended, but the stability of the suspension cannot be guaranteed. Therefore, under the friction force provided by the friction preload assembly 7, the stability of the suspension of the sliding front shell 3 is further improved to ensure that the sliding front shell 3 will not be out of control.

[0043] Optionally, the front housing base 2 is provided with a storage chamber 9 opening forward, and the sliding front housing 3 is also used to slide and open the storage chamber 9. Specifically, the analyzer body 1 also includes a storage chamber 9, and the front housing base 2 is provided with an opening communicating with the storage chamber 9.

[0044] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
