Technical Field

The utility model relates to the technical field of detection, in particular to sample detection equipment.

Background

In the application of sample detection technology, since a part of the sample has certain fluidity, the instruments, apparatuses and devices for detecting the sample generally have corresponding waterproof requirements. At present, waterproof purposes are achieved mainly by means of adding sealing rubber strips, spraying waterproof coatings, filling and sealing waterproof and the like, and for different sample detection devices, the waterproof means are selected by considering the factors of the structure, the inner space, the use environment and the like of the devices.

The sealing rubber strip is arranged between two adjacent components which are not easy to deform, and the sealing rubber strip is extruded by the two components to play a role in sealing and waterproofing. However, the sealing rubber strip is not suitable for all sample detection equipment, and the aging of the rubber strip also brings about the reduction of the waterproof performance, which is not beneficial to the stability of the sample detection equipment; the encapsulation and waterproof is to wrap and seal the whole body, so that great difficulty is brought to the disassembly, assembly and maintenance of the sample detection equipment; the waterproof coating can only be sprayed on the surface of the component, and cannot play a role in waterproof of the joint part on the sample detection equipment. Because need avoid the sample to be polluted in order to guarantee the accuracy of result among the sample detection technique, consequently sample check out test set can use plastics consumptive material with the position of sample contact, because the restriction of cost and material property, plastics consumptive material easily takes place deformation, needs the dismouting to change often simultaneously, and the fixed department of connection of consumptive material and equipment also has the seam, and these three kinds of means all are difficult to satisfy sample check out test set's waterproof demand.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The terms "first," "second," and the like in this disclosure are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "include," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the utility model. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

With the development of medical science and technology and detection technology, means for detecting various biochemical samples are gradually increased, the efficiency and the precision of detecting the samples are continuously improved, and the precision of various medical instruments, apparatuses or devices is also improved. Because some samples have certain fluidity, instruments, apparatuses and devices for detecting the samples generally have corresponding waterproof requirements so as to prevent the samples from leaking into the devices to influence the structure and performance of the devices. The waterproof grade of the equipment is from IPX1 to IPX8, and different grades correspond to different waterproof requirements.

The waterproof forms commonly used at present mainly comprise waterproof sealing rubber rings or sealing rubber strips, waterproof filling and sealing, waterproof coating and the like. Aiming at different products, different waterproof modes are needed to be adopted in consideration of the factors such as the structure, the function realization, the internal space, the use environment and the like of the instrument.

The sealing rubber ring or the sealing rubber strip is generally used for waterproof between components (such as metal pieces and rigid plastic pieces) which are not easy to deform, and the components extrude the rubber strip or the rubber ring to enable the rubber strip or the rubber ring to elastically deform, so that the space at the joint of the components is sealed. However, since the sample detection technology needs to avoid the sample from being polluted as much as possible to ensure the accuracy of the detection result, the part of the sample detection device contacted with the sample usually uses plastic consumable materials, and the plastic consumable materials are easy to deform under the stress due to the limitation of cost and material performance, and meanwhile, the plastic consumable materials also face the risk of aging. When the surface of the consumable is added with the sealing rubber ring and the rubber strip, once the consumable is deformed and aged, the sealing of the joint between the consumable and the sample detection equipment cannot be ensured, and the accuracy of the detection result cannot be ensured.

The potting waterproof is generally formed by wrapping and sealing the position to be sealed by using potting adhesive such as epoxy resin, so as to play a role in waterproof. For sample testing devices, whether the device is maintained or the consumable is replaced during daily use, the sample testing device needs to be disassembled for operation, and the usability of the sample testing device is seriously hampered by the use of potting and waterproofing. In addition, a common waterproof method is to spray waterproof paint on the surface of the product to form a waterproof coating, and for objects with smaller gaps and no need of disassembly and assembly, the waterproof paint covers the surface and seals the gaps to achieve the aim of waterproof well. However, for sample detection equipment, consumables and an equipment body can be frequently separated, the equipment body also has the requirement of disassembling and overhauling, and a gap on the sample detection equipment cannot be completely closed naturally, so that even if waterproof paint is sprayed on the surfaces of the equipment body and the consumables, samples cannot be prevented from leaking into the sample detection equipment from the gap.

How to provide a sample detection device, which can guide the sample leaked into the sample detection device without affecting the usability of the sample detection device, is a big problem to be solved by the sample detection device provided by the utility model.

FIG. 1 is an assembled schematic view of an embodiment of the sample testing device of the present utility model. Fig. 2 is a schematic view of the sample testing device of fig. 1 with the device panel removed. Fig. 3 is a schematic view of the structure of fig. 2 at another angle.

Referring to fig. 1 to 3, the present utility model provides a sample testing device, which includes a test card holder 2, a device panel 11 and a flow guiding component 3. The test card holder 2 has a sample inlet 21 for inputting a sample.

The equipment panel 11 is provided with a placement groove 111, the test card fixing piece 2 is at least partially embedded in the placement groove 111, and the sample inlet 21 is arranged above a joint 112 between the placement groove 111 and the test card fixing piece 2. For the sample testing device 1 in the present utility model, when the sample is introduced into the test card fixed in the test card holder 2 through the sample inlet 21, the sample may leak from the sample inlet 21 due to various external factors, and may drop into the joints 112 of the test card holder 2, the device panel 11 and both, so that the leaked sample with fluidity may penetrate into the interior of the sample testing device 1 through the joints 112, and even cause the function of the sample testing device 1 to be damaged. Therefore, at least a portion of the flow guide assembly 3 is disposed below the joint 112 to guide the sample leaking from the sample inlet 21 into the mounting groove 111 through the joint 112.

In order to better drain the leakage sample, the flow guiding assembly 3 may comprise a first flow guiding element 31. The first flow guide 31 includes a flow guide plate 311 and a first flow guide groove body 312 connected to each other. The upper end of the baffle 311 is adjacent to the joint 112, and the lower end is connected to the first drainage groove body 312 to guide the sample flowing in from the joint 112 into the first drainage groove body 312, thereby preventing the sample from further leaking out to damage the sample detection device.

Alternatively, since the tight fitting between the seam 112 and the baffle 311 is not necessarily achieved in practical applications, the outer wall of the test card holder 2 is provided with the first protruding portion 22 along the lower portion of the seam 112. One end of the baffle 311, which is close to the joint 112, is fixed to the outer wall of the test card holder 2 along the lower side of the first protrusion 22, so that the sample can smoothly flow onto the baffle 311 along the first protrusion 22 under the action of gravity.

Referring to fig. 1, 5 and 6, fig. 5 is a schematic cross-sectional view of a section of the sample detection apparatus B-B' of fig. 1. Fig. 6 is an enlarged sectional structural schematic view of the area a in fig. 5. The upper end of the deflector 311 is closely attached to the lower side of the first protruding portion 22, the first protruding portion 22 is disposed below the joint 112, and the joint is located below the sample inlet 21 of the test card holder 2 and near the equipment panel 11. When sample leakage occurs during sample introduction, the leaked sample can slide along the outer wall of the test card fixing piece 2 under the action of gravity from the sample introduction port 21, and under the action of the first protruding part 22, the sample penetrating into the joint 112 can slide downwards from between the first protruding part 22 and the equipment panel 11. Because the thickness of the first protruding portion 22 is greater than that of the baffle 311, and the baffle 311 is tightly connected with the first protruding portion 22, the sample flowing through the first protruding portion 22 and dropping sample into the sample detection device 1 can directly flow onto the baffle 311 from the lower side of the first protruding portion 22, and then flow into the first drainage groove 312 along the baffle 311.

Alternatively, the side of the device panel 11 facing the seam may be provided with a second protrusion 113. The second protruding portion 113 abuts against the first protruding portion 22, so that the test card fixing member 2 is prevented from falling out of the mounting groove 111, and stable mounting of the test card is ensured.

The flow guiding assembly 3 may further comprise a second flow guiding element 32, on the basis of the first flow guiding element 31. The second flow guide 32 comprises a effusion plate 322 and a second drainage channel body 321 connected to each other. The effusion plate 322 is disposed below the second drainage groove 321. And the upper end of the second drainage groove body 321 is received under the first drainage groove body 312, and the lower end is connected with the effusion plate 322, so as to drain the leakage sample drained from the first drainage groove body 312 onto the effusion plate 322.

Optionally, to achieve a better drainage effect, the second drainage groove 321 may be inclined towards the effusion plate 322, where the upper end of the second drainage groove 321 drains the leakage sample from the first drainage groove 312, and the lower end drains the sample onto the effusion plate 322.

Optionally, to achieve a better drainage effect, the first drainage groove body 312 may be inclined towards the second drainage groove body 321, so that the sample drained into the first drainage groove body 312 by the guiding plate 311 is smoothly drained into the second drainage groove body 321 under the action of gravity.

Further, as shown in fig. 3, the end of the effusion plate 322 connected with the second drainage groove body 321 may be inclined slightly downward, so that the end far away from the second drainage groove body 321 is higher than the end connected with the second drainage groove body 321, so as to accumulate the sample at the connection position of the effusion plate 322 and the second drainage groove body 321.

Alternatively, the upper end of the second drainage groove body 321 may be slightly wider than the end of the first drainage groove body 312 near the second drainage groove body 321. The projection of the first drainage groove body 312 in the vertical direction may at least partially cover the second drainage groove body 321. So that the second drainage groove body 321 can receive the whole sample as much as possible, and the sample is prevented from leaking in the process of draining from the first drainage groove body 312 to the second drainage groove body 321.

Referring to fig. 3, the edge of the effusion plate 322 may extend upward beyond the water deflector 323 to allow the samples to accumulate on the effusion plate 322, avoiding leakage after the samples are drained to the effusion plate 322.

Referring to fig. 4, the sample testing device 1 provided by the present utility model may further include a connector 4. The connecting piece 4 is fixed on one side of the equipment panel 11 near the second diversion piece 32, and extends downwards to form a first connecting part 41. The second connecting portion 324 may extend upward from the side of the effusion plate 322 of the second flow guiding member 32. The first connecting portion 41 is connected with the second connecting portion 324 to fix the effusion plate 322 with the connecting piece 4, and further fix the second flow guiding piece 32 with the equipment panel relatively, so as to ensure that the sample on the second flow guiding piece 32 is not easy to leak.

Alternatively, the flow guiding component 3 may be formed by processing a metal or alloy plate such as a steel plate, an aluminum plate, a copper plate, etc. through a sheet metal process. But also from other, more durable, plates, such as plastic plates. Further, a protective layer or a waterproof layer may be sprayed or electroplated on the surface of the flow guiding component 3, so as to avoid the material of the flow guiding component 3 from being damaged under the erosion of the sample, thereby reducing the stability of the sample detection device 1.

Referring to fig. 1, 3 and 4, the sample detection device 1 may further comprise a device base plate 5 and a control element 6. The device bottom plate 5 is disposed at the sample detection device bottom 1, and the control element 6 is mounted on the device bottom plate 5. In order to prevent leakage of the sample onto the control element 6 from affecting the function of the sample detection device 1, the flow guide assembly 3 should be at least partially arranged over the control element 6 to avoid contact of the sample with the control element 6.

Optionally, a third connection portion 325 may also extend downward from the side of the effusion plate 322 of the second flow guiding element 32. The third connecting portion 325 is fixed to the apparatus base plate 5, so that the second flow guiding member 32 is fixed above the control element 6 and the apparatus base plate 5 under the combined action of the third connecting portion 325 and the second connecting portion 324.

Alternatively and more specifically referring to fig. 1 and 5, for the sample detection device 1 provided by the present utility model, the sample detection device may further include a device main body 7 and an operation panel 8, where the device main body includes a housing 71, a control element 6, a device bottom plate 5, and the like, the housing 71 has a receiving cavity 72 therein, and the control element 6 and a part of the flow guiding assembly 3 are disposed in the receiving cavity 72. Wherein the top side of the housing is provided with an equipment panel 11 and the bottom side of the housing is provided with an equipment bottom plate 5. The control element 6 is configured to perform various functions (e.g., a sample detection function) of the sample detection apparatus 1 and control a state of the sample detection apparatus 1, and an operator may perform man-machine interaction through the operation panel 8, so as to issue an instruction to the control element 6. It should be noted that, since the control element 6 includes a large number of sensitive detecting devices and circuit elements, the flow guiding assembly 3 is optionally disposed between the seam 112 where the sample leaks and a part of the control element 6 that is easily damaged, so as to avoid that the leaked sample drips onto the control element 6 to adversely affect the function of the sample detecting apparatus 1.

Optionally, in order to smoothly complete the sample injection process, the sample detection device may further include a driving member, where the driving member is in driving connection with the test card in the test card fixing member 2, so as to drive the sample from the sample injection port 21 into the test card for performing the sample injection process.
