Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, and in particular to a boxed blood type card centrifuge. Background Art

[0002] Blood type cards are used for clinical blood type testing. The microcolumns of blood type cards are filled with gel, which occupies about 2 / 3 of the inner cavity volume, and the rest is air and diluent. The gel has a certain fluidity. During transportation, if there is a large vibration, it will detach from the middle and lower part of the microcolumn hole, shift or deform, or even adhere to the inner surface of the sealing film at the top of the gel card. Since the normal use of blood type cards requires the gel to be located in the middle and lower part of the microcolumn hole and keep the liquid level horizontal, the microcolumn gel card needs to be centrifuged after it reaches the user from the manufacturer to completely reset the gel. However, ordinary blood type card centrifuges can only centrifuge 24 blood type cards. It is necessary to take out a single card from the box and centrifuge it for about 5 minutes at a time, which is time-consuming and labor-intensive, resulting in low centrifugal efficiency.

[0034] Please refer to Figure 1-Figure 3 , this embodiment provides a boxed blood typing card centrifuge 100, the boxed blood typing card centrifuge 100 includes a base 110, a protective cover 120, a cover plate 130, a centrifugal column 140, a driving motor and a centrifugal support 150;

[0035] The protective cover 120 is connected to the base 110 and together define the centrifugal chamber 101, and the end of the centrifugal chamber 101 away from the base 110 is open; the cover plate 130 is movably connected to the protective cover 120 to close or open the end of the centrifugal chamber 101 away from the base 110; the centrifugal column 140 is rotatably connected to the base 110 and accommodated in the centrifugal chamber 101, the driving motor is connected to the base 110 and is transmission-connected to the centrifugal column 140; the centrifugal support 150 is connected to the centrifugal column 140 and accommodated in the centrifugal chamber 101, and the centrifugal support 150 is used to place at least one boxed blood type card.

[0036] Please refer to Figure 1-Figure 3 The working principle of the boxed blood type card centrifuge 100 is:

[0037] The boxed blood type card centrifuge 100 includes a base 110, a protective cover 120, a cover plate 130, a centrifugal column 140, a driving motor and a centrifugal support 150; the protective cover 120 is connected to the base 110 and together defines a centrifugal chamber 101, and the end of the centrifugal chamber 101 away from the base 110 is open; the cover plate 130 and the protective cover 120 are movably connected to close or open the end of the centrifugal chamber 101 away from the base 110; the centrifugal column 140 is rotatably connected to the base 110 and accommodated in the centrifugal chamber 101, the driving motor is connected to the base 110 and is transmission-connected to the centrifugal column 140; the centrifugal support 150 is connected to the centrifugal column 140 and accommodated in the centrifugal chamber 101, and the centrifugal support 150 is used to place at least one boxed blood type card.

[0038] It should be noted that, when configuring the centrifugal support 150, the present embodiment is explained by taking the centrifugal support 150 as an example in which a plurality of boxed blood type cards can be placed at the same time, and when configuring the centrifugal support 150, the centrifugal support 150 can be arranged correspondingly according to the structural dimensions of the boxed blood type cards, so that the structural shape of the centrifugal support 150 can be adapted to the boxed blood type cards, so as to increase the placement stability of the boxed blood type cards while reducing the size of the centrifugal support 150; in addition, since the boxed blood type cards have different sizes, the structure of the centrifugal support 150 can be optimized so that the boxed blood type cards of different size ranges can be placed, or centrifugal supports 150 of multiple structural dimensions can be arranged, each centrifugal support 150 is adapted to one or more sizes of boxed blood type cards, and then the centrifugal support 150 can be replaced according to the size of the boxed blood type cards;

[0039] In summary, the boxed blood type card centrifuge 100 directly loads the boxed blood type cards and performs centrifugation. Therefore, compared with the ordinary centrifuge in the prior art, the number of blood type cards that can be centrifuged in a single time can be increased, and the steps of taking the blood type cards out of the box can be reduced, so that the boxed blood type cards can be centrifuged in batches. The operation is simple and convenient, and the centrifugation efficiency of the blood type cards can be improved.

[0040] For further information, please refer to Figure 1-Figure 6 In this embodiment, the centrifugal support 150 is used to place multiple boxed blood type cards at the same time. Therefore, the centrifugal support 150 in this embodiment may include multiple sub-supports 151, each sub-support 151 is used to place at least one boxed blood type card; in this way, the number of boxed blood type cards that can be centrifuged at the same time is increased, thereby improving the centrifugal efficiency;

[0041] When configuring the sub-racks 151, in order to improve the placement stability of the boxed blood type cards in the sub-racks 151, each sub-rack 151 includes a frame body 152 and a positioning member 153; the frame body 152 is provided with a cavity 102 for placing the boxed blood type cards, and the cavity 102 is set according to the corresponding boxed blood type cards, and in order to facilitate the boxed blood type cards to be loaded into or removed from the cavity 102, the cavity 102 is open on one side away from the base 110; and in order to improve the stability of centrifugation, the positioning member 153 is connected to the frame body 152 and is used to press the boxed blood type cards in the cavity 102, so as to keep the boxed blood type cards placed in the cavity 102 during the centrifugation process and prevent them from leaving the cavity 102.

[0042] Furthermore, it can be seen from the above content that in this embodiment, when configuring the above-mentioned centrifuge rack, the structure of the centrifuge rack 150 can be optimized so that it can place boxed blood type cards of different size ranges, or, centrifuge racks 150 of multiple structural sizes are set, each centrifuge rack 150 corresponds to one or more sizes of boxed blood type cards, and then the centrifuge rack 150 can be replaced according to the size of the boxed blood type cards; based on this, in order to facilitate the adjustment of the installation state of the sub-rack 151, the multiple sub-racks 151 can be detachably connected to the centrifuge column 140.

[0043] Since there are many structural forms for realizing the detachable connection between the sub-bracket 151 and the centrifugal column 140, this embodiment takes the sliding groove structure as an example for explanation. Specifically, the outer peripheral surface of the centrifugal column 140 is provided with a plurality of first sliding connection parts 141, and the plurality of first sliding connection parts 141 extend along the center line direction of the centrifugal column 140 and are arranged at intervals around the center line direction of the centrifugal column 140; each frame 152 is provided with a second sliding connection part 142, and the second sliding connection part 142 is slidably matched with the first sliding connection part 141 along the center line direction of the centrifugal column 140; wherein one of the first sliding connection part 141 and the second sliding connection part 142 is a positioning sliding groove, and the other is a positioning protrusion. Thus, the connection state between the sub-bracket 151 and the centrifugal column 140 can be adjusted through the sliding match between the positioning sliding groove and the positioning protrusion, so as to facilitate the replacement or adjustment of the sub-bracket 151.

[0044] It should be noted that, from the above content, it can be seen that in this embodiment, the boxed blood type card is placed in the cavity 102 of the sub-bracket 151 and is compressed by the positioning piece 153. Based on this, when the boxed blood type card is loaded into the cavity 102 of the sub-bracket 151, the sub-bracket 151 can be removed from the centrifuge column 140 and the positioning piece 153 can be installed. Then, the sub-bracket 151 containing the boxed blood type card is installed in the centrifuge column 140, and then centrifugation is performed. Therefore, this installation method can reduce the difficulty of installing the boxed blood type card to improve the operating efficiency of the centrifugation.

[0045] For further information, please refer to Figure 1-Figure 6 On the basis of the above structure, when a plurality of sub-supports 151 are detachably connected to the centrifuge column 140, in order to improve the connection stability between the sub-supports 151 and the centrifuge column 140, the boxed blood type card centrifuge 100 further includes a limit cover, which is threadedly connected to the end of the centrifuge column 140 away from the base 110, and the limit cover is used to abut against the frame 152 connected to the centrifuge column 140 to limit the sliding of the frame 152 in the direction of separating from the centrifuge column 140. Therefore, by setting the limit cover, the sub-supports 151 can be prevented from sliding relative to each other during the centrifugation process, thereby improving the stability of the centrifugation.

[0046] Different from the above-mentioned manner in which multiple sub-supports 151 are detachably connected to the centrifuge column 140, in other embodiments of the present invention, the centrifuge support 150 can also include a mounting frame, the mounting frame is connected to the centrifuge column 140, and multiple sub-supports 151 are detachably connected to the mounting frame. Such a structural arrangement can achieve separation of multiple sub-supports 151 from the centrifuge column 140 through installation or disassembly of the mounting frame and the centrifuge column 140, and can also facilitate the loading of boxed blood type card centrifuges 100 into all sub-supports 151.

[0047] For further information, please refer to Figure 1-Figure 6 In this embodiment, when configuring the frame 152, each frame 152 may include a back plate 154, a bottom plate 155 and a fence 156. The bottom plate 155 and the fence 156 are connected to the back plate 154 and together enclose the cavity 102; the two ends of the positioning member 153 are respectively connected to the back plate 154 and the fence 156. Moreover, the fence 156 may include a railing and a fence. In this way, the strength of the frame 152 can be improved through the fence 156, and the structure of the frame 152 can be simplified. In addition, when installing the positioning member 153, the end of the positioning member 153 connected to the fence 156 can be connected to the railing, thereby improving the stability of the connection.

[0048] Please refer to Figure 1-Figure 6 In this embodiment, when configuring the positioning member 153, the positioning member 153 may be a flexible rope or a hard rod. In this embodiment, in order to improve the installation flexibility of the positioning member 153 and facilitate the connection or disconnection of the positioning member 153 with the frame 152, a first clamping portion 157 may be provided on the side of the back plate 154 away from the base 110, and a second clamping portion 158 may be provided on the end of the positioning member 153 used for connecting with the back plate 154, and the first clamping portion 157 and the second clamping portion 158 are engaged. Thus, the positioning member 153 can press and hold the boxed blood type cards in the cavity 102 through the engagement of the first clamping portion 157 and the second clamping portion 158, and the boxed blood type cards in the cavity 102 can be easily taken out through the disengagement of the first clamping portion 157 and the second clamping portion 158. It should be noted that the first clamping portion 157 and the second clamping portion 158 can adopt a locking structure, that is, one of them is a male buckle and the other is a female buckle.

[0049] Based on the above, please refer to Figure 1-Figure 6In this embodiment, when configuring the centrifugal column 140, the centrifugal column 140 can be configured as a polyhedron or a cylinder; wherein, when the centrifugal column 140 is configured as a polyhedron, taking the centrifugal column 140 as a hexagonal column as an example, each side of the centrifugal column 140 can be connected to a corresponding sub-bracket 151. When the centrifugal column 140 is cylindrical, in order to improve the connection stability between the sub-bracket 151 and the centrifugal column 140, the side of each sub-bracket 151 close to the centrifugal column 140 can be an arc with the same diameter as the centrifugal column 140, that is, the side of the back plate 154 in the above structure that is used to contact the centrifugal column 140 is an arc with the same diameter as the centrifugal column 140.

[0050] In summary, during the operation of the boxed blood type card centrifuge 100, the boxed blood type card is directly loaded into the centrifuge support 150, and the boxed blood type card placed in the centrifuge support 150 can have different sizes, and then the working state of the centrifuge motor is controlled to drive the centrifuge column 140 to rotate to achieve centrifugation, and then the gel in the card is completely reset by rotating centrifugation;

[0051] When controlling the operation of the centrifugal motor, the centrifugal motor can be controlled by configuring the control module, so as to control the parameters and time of the centrifugal process; and on this basis, the state of the centrifugal process can be monitored by configuring the display screen; for example, by controlling the speed of the centrifugal motor, the centrifugal force is divided into three gears of low speed, medium speed and high speed, and the low speed, medium speed and high speed three gears correspond to 1000, 2000 and 3000 RCF respectively, so as to achieve the gel reset effect at one time; in addition, the centrifugal time can be set to 1 minute, and the display screen shows the seconds. If the effect is achieved, the power can be directly turned off to stop the centrifugation;

[0052] Therefore, the boxed blood type card centrifuge 100 has the characteristics of simple structure and convenient operation, and is suitable for application scenarios such as high-throughput blood type card preparation in clinical blood type testing. Compared with ordinary centrifuges in the prior art, it can increase the number of blood type cards centrifuged in a single time and reduce the steps of taking the blood type cards out of the box, so that the boxed blood type cards can be centrifuged in batches. The operation is simple and convenient, and the centrifugation efficiency of the blood type cards can be improved.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
