Description

Technical Field

[0001] The present invention relates to the technical field of medical testing equipment, and in particular to a reagent card incubation device. Background Art

[0002] In the field of medical equipment, especially in fluorescence analyzers that require the incubation function of reagent cards, most of them need to place the reagent cards in a certain heating position for incubation. The traditional incubation method is to use a heating plate for heating, and the temperature of the reagent card is raised to a suitable temperature for incubation through heat conduction. A certain temperature value must be maintained for a long time to meet the incubation requirements. This incubation mode is to use a heating plate for local heating, and the heating temperature control is not precise. At the same time, the incubation method does not have a cooling device. When the temperature is too high, the temperature can only be gradually reduced by disconnecting the heating mode of the heating plate. When the temperature needs to be raised, the heating plate can only be powered on to increase the temperature. Frequent temperature rise and fall will cause large temperature changes and affect the incubation effect. In addition, the traditional incubation method is that heating is carried out through the joint action of the heating plate and the material in contact, and heat is transferred through heat conduction. It is easily affected by the heat-conducting material and the environment, resulting in uneven heating and poor heat dissipation, which further affects the incubation effect.

[0023] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] In the description of the invention, it should be understood that the invention uses the terms "first", "second", etc. to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] For the convenience of description, the directions mentioned below are explained as follows: Figure 1 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The left and right directions are consistent.

[0027] like Figures 1 to 4 As shown, this embodiment provides a reagent card incubation device, including a box body 1 with a cavity, an incubation chamber 2 installed in the cavity, a hot and cold all-in-one machine 3, and a liquid pump 4; the hot and cold all-in-one machine 3 has an infusion port and a liquid return port; the liquid pump 4 has a liquid inlet and a liquid outlet; a heater and a refrigerator are arranged inside the hot and cold all-in-one machine 3, which can heat and cool the liquid, and the liquid pump 4 provides power for the circulation of the liquid.

[0028] There are multiple incubation chambers 2 for storing reagent cards 6, all of which are spaced from top to bottom, and there are sealed channels between two adjacent incubation chambers 2, and the two adjacent sealed channels are connected to each other; the infusion port of the hot and cold all-in-one machine 3 is connected to the liquid inlet of the liquid pump 4, the liquid outlet of the liquid pump 4 is connected to the sealed channel at the bottom, and the liquid return port of the hot and cold all-in-one machine 3 is connected to the sealed channel at the top. After the hot and cold all-in-one machine 3 heats or cools the liquid, it is pumped into the bottom sealed channel in the cavity through the liquid pump 4. The liquid flows through all the sealed channels from bottom to top in turn and finally reaches the top sealed channel in the cavity. The liquid transfers heat to the incubation chambers 2 at the upper and lower ends of the sealed channel in the sealed channel, thereby changing the incubation temperature of the reagent card 6. After the heat of the liquid is absorbed by the reagent card 6, the liquid flows back to the hot and cold all-in-one machine 3 from the top sealed channel to continue heating or cooling. The liquid flows from bottom to top to ensure that the sealed channels are filled with liquid. The sealed channels are connected in series. When in use, the liquid inside the sealed channels flows continuously and rapidly, which can greatly reduce the temperature difference between each incubation chamber 2. In addition, the direction of liquid flow can also be set to flow from top to bottom, so that all pipes and sealed channels are filled with liquid to ensure that the sealed channels are always filled with liquid. In addition, all incubation chambers 2 can also be distributed from left to right.

[0029] Specifically, in one embodiment, the reagent card incubation device also includes a connecting tube 7; there are multiple connecting tubes 7 and they are arranged in sequence from top to bottom, and a first partition 8 is vertically installed in the cavity, and the upper and lower ends of the first partition 8 are fixedly connected to the inner wall of the cavity. The first partition 8 divides the cavity into an incubation chamber 9 and a pipe laying chamber 10, the incubation chamber 9 is on the left, and the pipe laying chamber 10 is on the right. Each incubation chamber 2 is installed in the incubation chamber 9, and each connecting tube 7 is located in the pipe laying chamber 10. The first partition 8 is provided with a plurality of liquid inlet holes and a plurality of liquid outlet holes; the plurality of liquid inlet holes and the plurality of liquid outlet holes correspond to each other one by one, and there is one liquid inlet hole and one liquid outlet hole at the same height. On the same vertical line, the liquid inlet holes and the liquid outlet holes are alternately arranged from top to bottom, so that the connecting tubes 7 are staggered from top to bottom, to prevent the connecting tubes 7 on the same vertical line from being too close to each other, causing interference in heat transfer. Multiple liquid inlet holes correspond to multiple sealed channels one by one, and multiple liquid outlet holes correspond to multiple sealed channels one by one. The liquid outlet hole of any sealed channel is connected to the liquid inlet hole of the sealed channel above it through a connecting pipe 7, the liquid inlet hole of the lowest sealed channel is connected to the liquid outlet of the liquid pump 4, and the liquid outlet hole of the lowest sealed channel is connected to the liquid return port of the hot and cold integrated machine 3.

[0030] Specifically, in one embodiment, each of the incubation chambers 2 includes a substrate 201; a liquid cooling plate 11 is installed in each of the sealed channels, and a groove is provided on the substrate 201, and the inner wall of the groove and the liquid cooling plate 11 together enclose an incubation chamber 5 for storing the reagent card 6. The grooves are arranged at intervals from left to right, and the grooves are located on the lower end surface of the substrate 201. The liquid cooling plate 11 is connected to the lower end surface of the substrate 201, so that the inner wall of the groove and the liquid cooling plate 11 enclose an incubation chamber 5 spaced from left to right. The reagent card 6 is placed in the incubation chamber 5, and the liquid cooling plate 11 can not only support the reagent card 6, but also transfer heat to the reagent card 6. The main body of the liquid cooling plate 11 is made of aluminum alloy, and the circulation of the liquid is realized by the liquid pump 4, and the temperature of the liquid is quickly transferred to the reagent card 6 of each incubation chamber 5 through the liquid cooling plate 11.

[0031] Specifically, in one embodiment, a temperature sensor is provided in the cavity. When the reagent card 6 needs to be cooled, the temperature of the cooled liquid is transferred to the incubation chamber 2 through the liquid cooling plate 11, thereby reducing the temperature in the incubation chamber 2. On the contrary, when the temperature sensor near the incubation chamber 2 detects that the temperature in the incubation chamber 2 is low, the refrigeration and heating module of the hot and cold all-in-one machine 3 starts heating, and the liquid pump 4 continuously extracts the heated liquid from the hot and cold all-in-one machine 3, and then flows through the liquid cooling plates 11 of each sealed channel along the liquid pipe, and then the temperature is transferred to the incubation chamber 5 of the incubation chamber 2 by the liquid cooling plate 11. The detection of the temperature sensor is real-time and uninterrupted, and the operation of the hot and cold all-in-one machine 3 and the liquid pump 4 is also real-time and uninterrupted, so that the temperature of the incubation chamber 5 of the incubation chamber 2 can be kept constant, making the reagent detection more accurate.

The base plate 201 can be locked in the first slide groove 801 by passing a pin or a bolt through the first positioning hole and the first threaded hole to prevent the base plate 201 from sliding out of the first slide groove 801.

[0037] Specifically, in one embodiment, a second threaded hole connected to the second slide groove 104 is provided on the left side plate 103 of the box body 1, and a second positioning hole matching the second threaded hole is provided on the base plate 201. The base plate 201 can be locked in the second slide groove 104 by passing a pin or a bolt through the second positioning hole and the second threaded hole to prevent the base plate 201 from sliding out of the second slide groove 104.

[0038] Specifically, in one embodiment, the length (left-right direction) of the substrate 201 is slightly larger than the length of the liquid cooling plate 11, and the thickness (up-down direction) of the liquid cooling plate 11 is equal to the distance between the two substrates 201. After the substrate 201 is inserted into the first slide groove 801 and the second slide groove 104, the liquid cooling plate 11 is directly inserted into the sealing channel for easy installation.

[0039] Specifically, in one embodiment, the distance between the rightmost incubation chamber 5 and the inner wall of the second slide groove 104 is greater than the inner wall thickness between two adjacent incubation chambers 5, and the distance between the leftmost incubation chamber 5 and the inner wall of the first slide groove 801 is greater than the inner wall thickness between two adjacent incubation chambers 5, ensuring that heat will not dissipate from both ends of the substrate 201 to the outside of the box 1.

[0040] Specifically, in one embodiment, both the left and right ends of the substrate 201 are chamfered to prevent the substrate 201 from getting stuck when being inserted into the first slide groove 801 and the second slide groove 104 .

[0041] Specifically, in one embodiment, the width of the incubation chamber 5 is 1.2-1.6 times the width of the reagent card 6 , and the thickness of the incubation chamber 5 is 1.2-1.3 times the thickness of the reagent card 6 , so that the incubation chamber 5 can only accommodate one reagent card 6 , and the reagent card 6 can also be easily inserted into the incubation chamber 5 .

[0042] Specifically, in one embodiment, the reagent card incubation device further includes a first delivery tube 12 ; the infusion port of the hot and cold all-in-one machine 3 is connected to the liquid inlet of the liquid pump 4 through the first delivery tube 12 .

[0044] Specifically, in one embodiment, the reagent card incubation device further includes a reflux pipe 14; the return port of the hot and cold integrated machine 3 is connected to the uppermost sealed channel through the reflux pipe 14. The reflux pipe 14 extends from the back of the box 1 into the pipe distribution chamber 10 and is connected to the uppermost liquid outlet.

[0045] Specifically, in one embodiment, the second delivery pipe 13 located in the pipe distribution chamber 10 is bent to prevent liquid from rushing into the sealing channel and causing liquid backflow, and also to prevent the water pressure of the liquid from damaging the liquid cooling plate 11 in the lowermost sealing channel.

[0046] Specifically, in one embodiment, the return pipe 14 connected to one end of the cold and hot machine 3 is bent, and the return pipe 14 bends upward and then bends downward to communicate with the return liquid port of the cold and hot machine 3, and the return pipe 14 is in an inverted U shape, so as to prevent the liquid in the sealed channel from directly flowing into the cold and hot machine 3 from the bottom to the bottom, thereby damaging the cold and hot machine 3.

[0047] Specifically, in one embodiment, the box body 1 includes a front plate 101, a rear plate 102, and four side plates 103 connected end to end, and the four side plates 103 connected end to end are respectively an upper side plate 103, a lower side plate 103, a left side plate 103, and a right side plate 103.

The front plate 101 is provided with a plurality of card holes 104, and the plurality of card holes 104 correspond to the plurality of incubation cavities 5 one by one. The reagent card 6 is placed into the incubation cavity 5 through the card holes 104. The card holes 104 can be rotatably mounted with a transparent glass sheet to prevent heat loss.

[0048] Specifically, in one embodiment, the uppermost incubation chamber 5 is fixed to the lower surface of the upper side plate 103.
