Description

Technical Field

[0001] This utility model relates to the field of blood testing technology, and in particular to a portable blood sample testing device. Background Technology

[0002] Blood testing is an indispensable core tool in clinical diagnosis, health screening, emergency treatment and outdoor medical care. The accuracy of the results directly depends on the efficient separation and processing of blood samples. As a key device for blood separation, the portability, stability and adaptability of centrifuges are crucial to the needs of mobile healthcare.

[0003] In the prior art, such as the Chinese patent CN221789680U "A Portable Blood Testing Centrifuge", a storage box is provided. The storage box has a placement slot, and a lifting plate is movably connected to the bottom wall of the placement slot. The centrifuge body is movably connected to the upper surface of the lifting plate. Movable slots are provided on both sides of the placement slot, and an electric telescopic rod is fixedly connected to the bottom wall of each movable slot. A fixing block is fixedly connected to the movable end of the electric telescopic rod, and a connecting plate is fixedly connected to the lower end of the fixing block. The connecting plate is fixedly connected to the lifting plate. A box lid is hinged to the upper surface of the storage box, and a docking block is fixedly connected to one side of the box lid. The storage box allows for the storage of the centrifuge body, preventing dust accumulation on its surface and the inconvenience of regular cleaning. Furthermore, the use of two electric telescopic rods allows the lifting plate to be raised and lowered via the connecting plate, thus raising and lowering the centrifuge body, facilitating flexible movement and carrying of the centrifuge body, and improving its usability.

[0004] While this type of blood sample testing equipment effectively stores and protects the centrifuge body and prevents dust accumulation, the centrifuge body and lifting plate lack precise positioning and a secure locking structure. They rely solely on simple placement or side protection for limiting movement, making them prone to shifting and collisions during transportation due to bumps. Furthermore, the carrying method is limited, relying only on the handle on the lid for manual carrying. When the overall weight of the equipment is significant, long-distance transport or frequent moves between multiple locations can easily lead to user fatigue. There is also a lack of a more labor-saving dragging and moving mode, thus requiring improvement. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where the centrifuge body and the lifting plate lack precise positioning and a firm locking structure, which makes it easy for the centrifuge body to move or even be damaged by collision during transportation due to bumps. At the same time, the carrying method is limited to carrying by hand, which makes it difficult to achieve labor-saving and efficient multi-scenario movement when the overall weight of the equipment is large. Therefore, this invention proposes a portable blood sample testing device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a portable blood sample testing device, comprising a storage box, an internal lifting plate, a centrifuge body on the upper surface of the lifting plate, a protective pad fixedly installed on the upper surface of the lifting plate, a connecting plate fixedly connected to the side of the lifting plate, a hydraulic cylinder fixedly installed on the inner side of the storage box, a lid hinged to the top of the storage box, a second protective pad fixedly installed on the lower surface of the lid, a handle fixedly installed on the upper surface of the lid, and a handle on the side of the lid. A locking block is fixedly connected to the surface of the storage box. A locking sleeve is provided on the side of the storage box. A fixing rod is threadedly connected to the side of the locking sleeve. An operation panel is provided on the surface of the storage box. A protrusion is fixedly connected to the side of the centrifuge body. A groove is provided on the surface of the connecting plate. A limiting sleeve is fixedly installed on the side of the connecting plate. A limiting rod is slidably connected inside the limiting sleeve. A limiting hole is provided on the side of the protrusion. A limiting plate is fixedly connected to the surface of the limiting rod. A tension spring is sleeved on the surface of the limiting rod. A pull plate is fixedly connected to the other end of the limiting rod.

[0007] Preferably, both the first protective pad and the second protective pad are made of natural rubber. The upper surface of the first protective pad is attached to the lower surface of the centrifuge body, the lower surface of the second protective pad is attached to the upper surface of the centrifuge body, and the output end of the hydraulic cylinder is fixedly connected to the lower surface of the connecting plate.

[0008] Preferably, the protrusion and the groove are slidably connected, the limiting rod and the limiting hole are slidably connected, one end of the tension spring is fixedly connected to the side of the limiting sleeve, and the other end of the tension spring is fixedly connected to the side of the limiting plate.

[0009] Preferably, the card block and the card sleeve are engaged, and the fixing rod passes through the card sleeve and the card block and is threadedly connected.

[0010] Preferably, the bottom of the storage box is fixedly equipped with casters, the side of the storage box is fixedly connected with a fixed base, the fixed base is rotatably connected with a rotating block, the rotating block has a rotating shaft running through it, the surface of the rotating block is fixedly connected with a vertical plate, the inside of the vertical plate is slidably connected with a telescopic plate, the upper surface of the telescopic plate is fixedly equipped with a handle, the inner side of the telescopic plate is fixedly connected with a tension spring, the inside of the telescopic plate is slidably connected with a pin, and pin holes are opened on both sides of the vertical plate.

[0011] Preferably, the rotating shaft is rotatably connected to the fixed base.

[0012] Preferably, one end of the tension spring is fixedly connected to the side of the pin, and the pin is slidably connected to the pin hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the centrifuge body is firmly positioned on the lifting plate by the precise sliding cooperation of the protrusion and the groove, combined with the locking structure of the limiting sleeve, the limiting rod and the limiting hole, and with the help of the continuous elastic force of the tension spring. This effectively solves the problem of easy movement during transportation. The protective pads one and two made of natural rubber are respectively attached to the upper and lower surfaces of the centrifuge body, which has a better shock absorption and cushioning effect and can fully absorb the impact of transportation bumps on the internal precision components. At the same time, the detachable design of the positioning structure allows the centrifuge to be quickly unlocked and used independently when the power is exhausted or the drive mechanism fails, ensuring normal operation even in extreme scenarios such as outdoor power outages.

[0014] 2. In this utility model, by setting universal wheels at the bottom of the storage box and designing a retractable pull rod mechanism on the side, together with the handle on the lid, a dual movement mode of hand carrying and dragging is realized, which greatly improves the portability of the equipment. Moreover, the telescopic plate achieves height adjustment and fixation through the cooperation of pin rod and pin hole, and the tension spring ensures locking stability, allowing users to flexibly adjust the height of the pull rod according to their height and usage scenario. This solves the problem that traditional portable centrifuges rely solely on hand carrying and are inconvenient to carry when heavy. It is particularly suitable for medical scenarios that require frequent movement, such as outdoor sampling and emergency transport. Attached Figure Description

Detailed Implementation

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a portable blood sample testing device, including a storage box 1, a lifting plate 2 inside the storage box 1, a centrifuge body 3 on the upper surface of the lifting plate 2, a protective pad 4 fixedly installed on the upper surface of the lifting plate 2, a connecting plate 5 fixedly connected to the side of the lifting plate 2, a hydraulic cylinder 6 fixedly installed on the inner side of the storage box 1, a box cover 7 hinged to the top of the storage box 1, a protective pad 8 fixedly installed on the lower surface of the box cover 7, a handle 9 fixedly installed on the upper surface of the box cover 7, a locking block 10 fixedly connected to the side of the box cover 7, a retaining sleeve 11 on the side of the storage box 1, a fixing rod 12 threadedly connected to the side of the retaining sleeve 11, an operation panel 13 on the surface of the storage box 1, a protrusion 14 fixedly connected to the side of the centrifuge body 3, a groove 15 on the surface of the connecting plate 5, and a limiting sleeve 16 fixedly installed on the side of the connecting plate 5. An internal sliding connection is provided with a limiting rod 17, a limiting hole 18 is provided on the side of the protrusion 14, a limiting plate 19 is fixedly connected to the surface of the limiting rod 17, a tension spring 20 is sleeved on the surface of the limiting rod 17, and a pull plate 21 is fixedly connected to the other end of the limiting rod 17. The protective pad 1 4 and the protective pad 2 8 are both made of natural rubber. The upper surface of the protective pad 1 4 is in contact with the lower surface of the centrifuge body 3, and the lower surface of the protective pad 2 8 is in contact with the upper surface of the centrifuge body 3. The output end of the hydraulic cylinder 6 is fixedly connected to the lower surface of the connecting plate 5. The protrusion 14 and the groove 15 are slidably connected. The limiting rod 17 and the limiting hole 18 are slidably connected. One end of the tension spring 20 is fixedly connected to the side of the limiting sleeve 16, and the other end of the tension spring 20 is fixedly connected to the side of the limiting plate 19. The locking block 10 and the locking sleeve 11 are locked together. The fixing rod 12 passes through the locking sleeve 11 and the locking block 10 and is threadedly connected.

[0020] In this embodiment, when the centrifuge body 3 needs to be used, first loosen the fixing rod 12 to disengage it from the locking block 10, open the box cover 7, and control the hydraulic cylinder 6 to extend through the operation panel 13. The hydraulic cylinder 6 pushes the connecting plate 5 upward, causing the lifting plate 2 and the centrifuge body 3 to rise to the working height. When it is necessary to fix the centrifuge body 3, align the protrusion 14 at the bottom of the centrifuge body 3 with the protrusion 15 on the connecting plate 5 and insert it. At this time, pull the pull plate 21, which drives the limiting rod 17 to move outward, compressing the tension spring 20. The limiting rod 17 disengages from the limiting hole 18. After the protrusion 14 is fully inserted into the protrusion 15, release the pull plate 21, and the tension spring 20 will... Under the action of elasticity, the limiting rod 17 automatically inserts into the limiting hole 18 on the side of the protrusion 14 to achieve a firm fixation of the centrifuge body 3. When it is necessary to remove the centrifuge body 3, pull the pull plate 21 again to make the limiting rod 17 disengage from the limiting hole 18, and the centrifuge body 3 can be taken out from the protrusion 15. After use, control the hydraulic cylinder 6 to retract, drive the lifting plate 2 and the centrifuge body 3 to descend into the storage box 1, close the box cover 7 to make the locking block 10 insert into the locking sleeve 11, tighten the fixing rod 12 to lock it. The protective pad 1 4 and the protective pad 2 8 provide buffer protection for the centrifuge body 3 from the top and bottom, respectively, effectively preventing damage to the precision parts of the centrifuge during transportation.

[0021] Example 2: As Figures 1-5 As shown, a caster wheel 22 is fixedly installed at the bottom of the storage box 1. A fixed base 23 is fixedly connected to the side of the storage box 1. A rotating block 24 is rotatably connected inside the fixed base 23. A rotating shaft 25 is passed through the inside of the rotating block 24. A vertical plate 26 is fixedly connected to the surface of the rotating block 24. A telescopic plate 27 is slidably connected inside the vertical plate 26. A handle 28 is fixedly installed on the upper surface of the telescopic plate 27. A tension spring 29 is fixedly connected to the inner side of the telescopic plate 27. A pin 30 is slidably connected inside the telescopic plate 27. Pin holes 31 are opened on both sides of the vertical plate 26. The rotating shaft 25 is rotatably connected to the fixed base 23. One end of the tension spring 29 is fixedly connected to the side of the pin 30. The pin 30 is slidably connected to the pin hole 31.

[0022] In this embodiment, when the storage box 1 needs to be moved, the rotating block 24 can be rotated and unfolded from the fixed base 23 via the rotating shaft 25, so that the upright plate 26 is in a vertical working position. Then, the handle 28 is pulled to lift it upward, and the telescopic plate 27 slides upward inside the upright plate 26. When the appropriate height is reached, the pin 30 automatically pops out under the action of the tension spring 29 and inserts into the corresponding height pin hole 31, thereby locking the height of the telescopic plate 27. At this time, the entire storage box 1 can be moved by dragging it with the handle 28, and the caster wheel 22 provides flexible movement support. This greatly reduces the burden of carrying. When the pull rod mechanism needs to be stored, press the pin 30 to disengage it from the pin hole 31, press down the pull handle 28 to make the telescopic plate 27 completely retract into the upright plate 26, and then rotate the rotating block 24 back into the fixed seat 23 through the rotating shaft 25, so that the entire pull rod mechanism fits against the side of the storage box 1, reducing the space occupied. This solves the problem of fatigue caused by carrying the heavy traditional portable centrifuge for a long time. It is especially suitable for medical personnel who frequently move between different testing points, greatly improving the portability and ease of operation of the equipment.

[0023] The working principle of this embodiment is as follows: When using the centrifuge body 3, first loosen the fixing rod 12 to disengage it from the locking block 10, open the box cover 7, and control the hydraulic cylinder 6 to extend through the operation panel 13. The hydraulic cylinder 6 pushes the connecting plate 5 upward, causing the lifting plate 2 and the centrifuge body 3 to rise to the working height. When it is necessary to fix the centrifuge body 3, align the protrusion 14 at the bottom of the centrifuge body 3 with the protrusion 15 on the connecting plate 5 and insert it. At this time, pull the pull plate 21, which causes the limit rod 17 to move outward, compressing the tension spring 20. The limit rod 17 disengages from the limit hole 18, and the protrusion 14 is then fixed. After block 14 is fully inserted into the groove 15, release the pull plate 21. Under the elastic force of the tension spring 20, the limiting rod 17 automatically inserts into the limiting hole 18 on the side of the protrusion 14, thus firmly fixing the centrifuge body 3. When it is necessary to remove the centrifuge body 3, pull the pull plate 21 again to disengage the limiting rod 17 from the limiting hole 18, and the centrifuge body 3 can be removed from the groove 15. After use, control the hydraulic cylinder 6 to retract, driving the lifting plate 2 and the centrifuge body 3 to descend into the storage box 1. Close the box cover 7 so that the locking block 10 is inserted into the locking sleeve 11, tighten the fixing rod 12 to lock it, and the protective pad 4 and the anti- The second protective pad 8 cushions the centrifuge body 3 from both the top and bottom, effectively preventing damage to the centrifuge's precision components from vibrations during transportation. When the storage box 1 needs to be moved, the rotating block 24 can be rotated and unfolded from the fixed base 23 via the rotating shaft 25, so that the upright plate 26 is in a vertical working position. Then, the handle 28 is pulled upwards, and the telescopic plate 27 slides upwards inside the upright plate 26. When the appropriate height is reached, the pin 30 automatically pops out under the action of the tension spring 29 and inserts into the corresponding height pin hole 31, thereby locking the height of the telescopic plate 27. At this time, the entire storage box 1 can be dragged by the handle 28. The storage box 1 moves, and the casters 22 provide flexible support, greatly reducing the burden of carrying. When the pull rod mechanism needs to be stored, press the pin 30 to disengage it from the pin hole 31, press down the pull handle 28 to make the telescopic plate 27 completely retract into the upright plate 26, and then rotate the rotating block 24 back into the fixed seat 23 through the rotating shaft 25, so that the entire pull rod mechanism fits against the side of the storage box 1, reducing the space occupied. This solves the problem of fatigue caused by carrying the heavy traditional portable centrifuge for a long time. It is especially suitable for medical personnel to frequently move between different testing points, greatly improving the portability and ease of operation of the equipment.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
