Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically to a reagent bottle adapter in an in vitro diagnostic instrument. Background Art

[0002] In vitro diagnostic instruments are specialized equipment used in the field of clinical medicine for various biochemical, immunological, microbiological, hematological and other analyses. These instruments can accurately analyze patient samples, thereby assisting doctors in diagnosing diseases and formulating treatment plans. With the continuous development of science and technology, in vitro diagnostic instruments are becoming more and more intelligent and automated, improving the accuracy and efficiency of clinical tests.

[0003] Reagent bottles are used to store and transport various in vitro diagnostic reagents. They ensure the stability and effectiveness of the reagents during storage and use. They are an indispensable part of in vitro diagnostic instruments. The storage and use of reagent bottles are crucial to the accuracy of in vitro diagnosis. Reagent bottles should be stored in a dry, cool, dark place, away from direct sunlight and high temperatures. Especially during use, they should be sealed to avoid the evaporation of water in the reagents, which will cause the reagents to become ineffective, and ensure the effectiveness of the reagents during use.

[0004] Existing in vitro diagnostic instruments all use a gasket to prevent the evaporation of reagent water in the reagent bottle. However, this method works well for a short period of time. However, if it is left for a long time, the concentration of the reagent in the reagent bottle will still change because the gasket alone cannot effectively prevent the evaporation of reagent water in the reagent bottle, thereby causing the instrument to affect the test results due to the change in reagent concentration. Utility Model Content

[0005] The purpose of the present application is to provide a reagent bottle adapter in an in vitro diagnostic instrument to solve the problem that existing in vitro diagnostic instruments all use a gasket on the reagent bottle cap to prevent the evaporation of reagent water. Since a simple gasket cannot effectively prevent the evaporation of reagent water in the reagent bottle, the reagent concentration in the reagent bottle will still change, thereby causing the instrument to affect the test results due to the change in reagent concentration.

[0006] The technical solutions adopted in this application are as follows:

[0007] A reagent bottle adapter in an in vitro diagnostic instrument, comprising: an adapter body, wherein a catheter insertion hole, a position limiting hole, and a fixed sleeve insertion hole are sequentially arranged in the interior of the adapter body along the axial direction thereof from top to bottom, wherein a passage formed by the catheter insertion hole, the position limiting hole, and the fixed sleeve insertion hole passes through the adapter body, and a waterproof breathable valve installation hole is also arranged on the adapter body in a direction perpendicular to the axial direction of the fixed sleeve insertion hole, wherein the waterproof breathable valve installation hole is connected to the fixed sleeve insertion hole;

[0008] A catheter is arranged in the catheter insertion hole, a fixed sleeve is arranged in the fixed sleeve insertion hole, a waterproof breathable valve is installed in the waterproof breathable valve installation hole, the catheter is inserted into the catheter insertion hole, enters the fixed sleeve after passing through the limiting hole, the fixed sleeve is inserted into the fixed sleeve insertion hole, the waterproof breathable valve enters the fixed sleeve insertion hole through the waterproof breathable valve installation hole, and the fixed sleeve located in the fixed sleeve insertion hole is fixed;

[0009] A fitting section is provided at the lower portion of the adapter body, and a size of the fitting section is designed to be able to pass through the cap of the reagent bottle.

[0010] As a further improved technical solution of the present application, the diameter of the limiting hole is smaller than the diameters of the catheter insertion hole and the fixing sleeve insertion hole.

[0011] As a further improved technical solution of the present application, the waterproof breathable valve and the waterproof breathable valve mounting hole are connected by threads.

[0012] As a further improved technical solution of the present application, an O-ring is provided on the waterproof breathable valve.

[0013] As a further improved technical solution of the present application, the outer wall of the mating section is provided with threads, the mating section is inserted into the reagent bottle cap, and the mating section is sealed and connected to the reagent bottle cap through a gasket and a nut.

[0014] As a further improved technical solution of the present application, one end of the fixed sleeve is inserted into the bottom of the fixed sleeve insertion hole, and the other end extends toward the bottom of the bottle in the reagent bottle and is flush with the end close to the bottom of the bottle.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] The present application provides a reagent bottle adapter device in an in vitro diagnostic instrument. In order to effectively prevent the evaporation of water in the reagent and affect the reagent effect, the adapter device is provided with a fixed sleeve insertion hole and a waterproof breathable valve insertion hole on the adapter body, and the fixed sleeve and the waterproof breathable valve are inserted respectively. The waterproof breathable valve is used to effectively prevent the evaporation of water in the reagent based on the principle that air can only pass through but not water, thereby solving the problem that the instrument will not affect the test results due to changes in concentration caused by long-term use of the reagent. The waterproof breathable valve can fix the fixed sleeve while playing a ventilation role, effectively avoiding fixation failure caused by shaking caused by the reagent bottle, thereby improving the stability of the entire device.

[0017] On the other hand, the device is connected to the reagent bottle cap through a matching section, and is connected to the external catheter through a fixed sleeve. The reagent in the reagent bottle is discharged through the fixed sleeve and the catheter in turn. The entire reagent bottle adapter has a simple structure and is easy to install.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected", "connected", "set", and "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. All directional indications (such as up, down, left, right, front, back, etc.) in the implementation mode of this application are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. The following describes its embodiments based on the overall structure of this application.

[0029] like Figure 1-4 As shown, the present embodiment provides a reagent bottle adapter device in an in vitro diagnostic instrument, comprising: an adapter body 100, wherein a catheter insertion hole 110, a limiting hole 120, and a fixed sleeve insertion hole 130 are sequentially arranged in the interior of the adapter body 100 along its axial direction from top to bottom, and a passage composed of the catheter insertion hole 110, the limiting hole 120, and the fixed sleeve insertion hole 130 passes through the adapter body 100, and a waterproof breathable valve mounting hole 140 is further arranged on the adapter body 100 in a direction perpendicular to the axial direction of the fixed sleeve insertion hole 130, and the waterproof breathable valve mounting hole 140 is connected to the fixed sleeve insertion hole 130; a waterproof breathable valve mounting hole 140 is arranged in the catheter insertion hole 110 A catheter 200 is arranged, a fixed sleeve 300 is arranged in the fixed sleeve insertion hole 130, and a waterproof breathable valve 400 is installed in the waterproof breathable valve installation hole 140. The catheter 200 is inserted into the catheter insertion hole 110, and enters the fixed sleeve 300 after passing through the limiting hole 120. The fixed sleeve 300 is inserted into the fixed sleeve insertion hole 130, and the waterproof breathable valve 400 enters the fixed sleeve insertion hole 130 through the waterproof breathable valve installation hole 140, so as to fix the fixed sleeve 300 located in the fixed sleeve insertion hole 130; a matching section 150 is arranged at the lower part of the adapter body 100, and the size of the matching section 150 is designed to pass through the reagent bottle cap 510.

[0030] In this embodiment, the catheter 200 and the fixed sleeve 300 can adopt different shapes according to different actual application conditions. They can be hard glass tubes or soft rubber tubes. The structures can be, for example but not limited to, straight tubes, elbow tubes, etc. Since this is not the main content of the present invention, the structure of the catheter 200 and the fixed sleeve 300 will not be described in detail here.

[0031] In this embodiment, the term "axial direction" refers to the direction along the maximum dimension of the device or component. In some embodiments, when the adapter body 100 is installed on the reagent bottle cap 510, if the fixed sleeve 300 is a right-angle elbow tube, the axial direction of the adapter body 100 is a vertical direction. However, it should be understood that, depending on the application, the "axial direction" may not be a vertical direction, but a desired orientation (for example, an inclined orientation relative to a vertical line).

[0032] When the device of this embodiment is used, the adapter body 100 is first sealed and connected with the reagent bottle cap 510 through the matching section 150, and the catheter 200, the fixed sleeve 300, the waterproof breathable valve 400 are connected with the catheter insertion hole 110, the fixed sleeve insertion hole 130 and the waterproof breathable valve installation hole 140 in turn, and then the reagent bottle cap 510 is connected with the reagent bottle 500. In order to ensure the anti-evaporation performance of the adapter device, it is usually necessary to at least ensure the sealing between the interconnected components.

[0033] In this embodiment, a fixed sleeve insertion hole 130 and a waterproof breathable valve insertion hole 140 are provided on the adapter body 100, into which the fixed sleeve 300 and the waterproof breathable valve 400 are inserted respectively. The waterproof breathable valve 400 can only allow air to pass but not water to pass, thereby effectively preventing the evaporation of water in the reagent, thereby solving the problem that the instrument will not be affected by the concentration change caused by long-term use of the reagent and affecting the test results. The waterproof breathable valve 400 can fix the fixed sleeve 300 while playing a ventilation role, effectively avoiding the fixation failure caused by the shaking of the reagent bottle, thereby improving the stability of the entire device. The reagent in the reagent bottle 500 is discharged through the fixed sleeve 300 and the catheter 200 for use by the in vitro diagnostic instrument.

[0034] like Figure 4 As shown, the diameter of the limiting hole 120 is smaller than the diameter of the catheter insertion hole 110 and the fixed sleeve insertion hole 130. In this embodiment, the limiting hole 120 is arranged between the catheter insertion hole 110 and the fixed sleeve insertion hole 130. The catheter 200 is inserted into the catheter insertion hole 110 and enters the fixed sleeve 300 after passing through the limiting hole 120. The setting of the limiting hole 120 makes the installation of the catheter 200 more stable and improves the sealing performance of the adapter. For the fixed sleeve 300, the setting of the limiting hole 120 limits the insertion depth of the fixed sleeve 300 in the adapter body 100. By adjusting the position of the limiting hole 120, different connection requirements can be met.

[0035] like Figure 5, which is a schematic diagram of the structure of a waterproof sealing valve 400 provided in another embodiment of the present application, wherein the waterproof breathable valve 400 is installed in the waterproof breathable valve installation hole 140, and the waterproof breathable valve 400 and the waterproof breathable valve installation hole 140 are connected by threads. In this embodiment, the waterproof breathable valve installation hole 140 is connected to the fixed sleeve insertion hole 130, and the waterproof breathable valve 400 enters the fixed sleeve insertion hole 130 while playing a waterproof and breathable role, and compresses the fixed sleeve 300 located in the fixed sleeve insertion hole 130, so that the fixed sleeve 300 is installed more stably and is not easy to fall off.

[0036] On the adapter body 100 , the number of the waterproof breathable valve 400 and the waterproof breathable valve mounting hole 140 can be set according to the size of the adapter body 100 and the reagent performance requirements, for example, one or more.

[0037] On the other hand, Figure 5 As shown, in order to ensure the sealing performance of the entire reagent bottle adapter after the waterproof breathable valve 400 is installed in the waterproof breathable valve installation hole 140, an O-ring 410 is provided on the waterproof breathable valve 400 in this embodiment.

[0038] like Figure 6 As shown in the exploded view of the overall structure of the reagent bottle adapter in the provided in vitro diagnostic instrument after the reagent bottle is installed, a matching section 150 is provided at the lower part of the adapter body 100, and the size of the matching section 150 is designed to pass through the reagent bottle cap 510. In this embodiment, the adapter is connected to the reagent bottle cap 510 through the matching section 150, and then connected to the reagent bottle 500 through the reagent bottle cap 510, and finally the connection between the adapter and the reagent bottle in this embodiment is realized. The sealing performance of the connection between the matching section 15 and the reagent bottle cap 510 directly affects the effect of the device of this application on preventing the evaporation of water in the reagent in the reagent bottle. In order to improve the sealing performance of the connection between the matching section 15 and the reagent bottle cap 510, in this embodiment, the outer wall of the matching section 150 is provided with a thread, and the matching section 150 is inserted into the reagent bottle cap 510, and the matching section 150 is sealed and connected with the reagent bottle cap 510 through the gasket 600 and the nut 700.

[0039] like Figure 6 As shown, when the device is in use, the reagent in the reagent bottle 500 is discharged through the fixed sleeve 300. In order to fully discharge the reagent in the reagent bottle, in this embodiment, one end of the fixed sleeve 300 is inserted into the bottom of the fixed sleeve insertion hole 130, and the other end extends toward the bottom of the bottle in the reagent bottle 500 and is flush with the end close to the bottom of the bottle.

[0040] The fixed sleeve 300 may include features, such as but not limited to a chamfer, at one end thereof located in the body of the reagent bottle 500 to facilitate the absorption of the reagent. In view of the fact that this is not the main content of the present invention, the structure of the fixed sleeve 300 and the body of the reagent bottle 500 will not be described in detail here.

[0041] Although various embodiments of the present application are described in the drawings with reference to examples of reagent bottle adapters in in vitro diagnostic instruments, it should be understood that embodiments within the scope of the present application may be applied to other experimental reagent bottles having similar structures and / or functions, etc.
