Description

Technical Field

[0001] This utility model relates to the field of blood testing, and more specifically, to a blood test slide transport device. Background Technology

[0002] In the process of pathological research and detection of tumors, it is inevitable to use various pathological slides. These slides are usually prepared as specimens using glass slides and coverslips before being studied. In existing technologies, slides are typically handled by operators using tweezers during transport. However, using tweezers can easily damage or even cause the slides to fall. To address this, patent application CN202120286415.5 discloses a slide transport device for lymphoma blood tests, comprising a cylindrical shell, a first cylinder, a suction cup, and a clamping unit. The first cylinder is inserted into the cylindrical shell; the suction cup is fixed to the bottom of the first cylinder; a clamping unit is located inside the first cylinder; the clamping unit includes a first push rod, a first push plate, a first annular plate, a second push rod, and a second annular plate; the first push rod passes through the first cylinder and is slidably connected to it; the first push plate is fixed to its top; the second push rod passes through the first cylinder and is slidably connected to it; the first annular plate is fixed to the top of the second push rod; and the second annular plate is fixed to the bottom of the second push rod. This facilitates the suction of slides and thus enables their transport.

[0003] However, the above solution still has certain drawbacks. The inventors found through research that in the above solution, the suction cup is driven by the clamping unit to adsorb and grasp the slice. When it is necessary to separate the suction cup and the slice, external force is required to release it. If the external force is not applied properly, it may cause the slice to be damaged or fall off. In addition, when the external force is applied to release the suction, the slice may come into contact with other objects, which may also cause contamination of the slice.

[0004] How to invent a blood sample transport device to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a blood test slide transport device, which aims to improve the situation where the slide is adsorbed and gripped by the suction cup driven by the clamping unit. When it is necessary to separate the suction cup and the slide, external force is required to release it. If the external force is not applied properly, it may cause the slide to be damaged or fall off. In addition, when the external force is applied to release the suction, the slide may come into contact with other objects, which may also cause slide contamination.

[0006] This utility model is implemented as follows: A blood test slide transport device includes an outer cover, a partition integrally formed between the inner walls of the outer cover, through holes coaxially formed on the top surface of the outer cover and the top surface of the partition, a connecting tube slidably connected in the two through holes, a pressing plate connected above the outer cover by an elastic guide, a sealing plug fixedly installed on the bottom surface of the pressing plate, the sealing plug being connected to the top end of the connecting tube, a suction cup connected to the bottom end of the connecting tube, and an auxiliary exhaust and flattening assembly sleeved on the outside of the outer cover.

[0007] In a preferred embodiment of this utility model, the elastic guide is two guide telescopic rods, which are located on both sides of the upper surface of the outer cover. The two ends of each guide telescopic rod are fixedly connected to the upper surface of the outer cover and the bottom surface of the pressing plate, respectively. Each guide telescopic rod is fitted with a first spring, and the two ends of each first spring are fixedly connected to the upper surface of the outer cover and the bottom surface of the pressing plate, respectively.

[0008] In a preferred embodiment of this utility model, a connecting plate is integrally provided on the outer wall of the connecting pipe above the partition, and a second spring is sleeved on the portion of the connecting pipe located between the partition and the connecting pipe. The two ends of the second spring are respectively fixedly connected to the upper surface of the partition and the bottom surface of the connecting plate.

[0009] In a preferred embodiment of this utility model, the auxiliary exhaust flattening assembly includes an annular sleeve plate and a collar. The annular sleeve plate and the collar are coaxially arranged and slidably sleeved outside the connecting pipe and located below the partition. The annular sleeve plate and the collar are fixedly connected by a plurality of annularly evenly distributed connecting rods. One end of a plurality of annularly evenly distributed rotating rods is rotatably connected to the bottom surface of the annular sleeve plate. The other end of each rotating rod is rotatably mounted with a flattening exhaust roller. One end of a third spring is fixedly connected to one side surface of each rotating rod. The other end of each third spring is fixedly connected to the outer wall of the collar. A fourth spring is provided on both sides of the upper surface of the annular sleeve plate. The two ends of each fourth spring are fixedly connected to the upper surface of the annular sleeve plate and the bottom surface of the partition, respectively. The annular sleeve plate is slidably connected to the outer cover by a pressing and limiting mechanism.

[0010] In a preferred embodiment of this utility model, the pressing and limiting mechanism includes an extension integrally disposed on the side wall of the annular sleeve plate. One end of the extension is rotatably connected to one end of a toggle rod, and the other end of the toggle rod extends to the outside of the outer cover through an extension groove opened on the inner wall of one side of the outer cover. The bottom end of the extension groove is located on the inner wall of one side of the outer cover and is also connected to a limiting groove.

[0013] The beneficial effects of this utility model are as follows: The blood test slide transport device obtained by the above design can, in use, switch between sealed and unobstructed states by setting the suction cup at one end of the connecting tube and by using the sealing plug connected to it. This allows the suction cup to detach from the slide without applying external force after adsorbing it, thereby further improving the safety and convenience of slide transport and reducing the limitations caused by the slide being difficult to detach from the suction cup.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a blood test slide transport device, including an outer cover 1, a partition 101 integrally arranged between the inner walls of the outer cover 1, through holes coaxially opened on the top surface of the outer cover 1 and the top surface of the partition 101, a connecting pipe 2 slidably connected in the two through holes, a pressing plate 3 connected above the outer cover 1 through an elastic guide, a sealing plug 4 fixedly installed on the bottom surface of the pressing plate 3, the sealing plug 4 being connected to the top end of the connecting pipe 2, a suction cup 5 connected to the bottom end of the connecting pipe 2, and an auxiliary exhaust flattening component 6 sleeved on the outside of the outer cover 1.

[0022] Please see Figure 2 and Figure 3 The elastic guide consists of two guide telescopic rods 102, which are located on both sides of the upper surface of the outer cover 1. The two ends of each guide telescopic rod 102 are fixedly connected to the upper surface of the outer cover 1 and the bottom surface of the pressing plate 3, respectively. Each guide telescopic rod 102 is fitted with a first spring 103, and the two ends of each first spring 103 are fixedly connected to the upper surface of the outer cover 1 and the bottom surface of the pressing plate 3, respectively.

[0023] When the slice needs to be gripped and transported, the user presses down the pressing plate 3 to compress the guide telescopic rod 102, causing the sealing plug 4 to descend. After the sealing plug 4 is inserted into the top of the connecting tube 2, the top of the connecting tube 2 is sealed. Then, the pressing plate 3 moves down, causing the connecting tube 2 to continue to descend, pressing the suction cup 5 flat on the slice surface. During the deformation process of the suction cup 5 and the process of the sealing plug 4 being inserted into the top of the connecting tube 2, a part of the air inside the connecting tube 2 and the suction cup 5 is discharged, creating a pressure difference with the outside, so that the suction cup 5 is attached to the slice surface to complete the gripping of the slice. When it is time to put down the slice, the user releases the pressing plate 3. Under the action of the first spring 103, the pressing plate 3 moves upward to reset. After the sealing plug 4 is disconnected from the top of the connecting tube 2, air enters the connecting tube 2, so that the internal and external pressure difference is equalized, and the suction cup 5 is released from the suction of the slice.

[0024] Furthermore, a connecting plate 201 is integrally provided on the outer wall of the connecting pipe 2 above the partition 101, and a second spring 202 is sleeved on the part of the connecting pipe 2 located between the partition 101 and the connecting pipe 2. The two ends of the second spring 202 are respectively fixedly connected to the upper surface of the partition 101 and the bottom surface of the connecting plate 201.

[0025] When the user releases the pressing plate 3 to detach the suction cup 5 from the slice surface, the pressing plate 3 and the sealing plug 4 rise and reset under the force of the first spring 103, and the connecting tube 2 and the suction cup 5 rise and reset under the force of the second spring 202 so as to grab subsequent slices again, avoiding contamination caused by the suction cup 5 failing to reset and coming into contact with other objects.

[0026] Please see Figure 3 and Figure 4 The auxiliary exhaust flattening assembly 6 includes an annular sleeve 601 and a collar 602. The annular sleeve 601 and the collar 602 are coaxially arranged and slidably sleeved outside the connecting pipe 2 and located below the partition 101. The annular sleeve 601 and the collar 602 are fixedly connected by a number of annularly evenly distributed connecting rods 603. The bottom surface of the annular sleeve 601 is rotatably connected to one end of a number of annularly evenly distributed rotating rods 604. The other end of each rotating rod 604 is rotatably mounted with an exhaust flattening roller 605. One end of a third spring 606 is fixedly connected to one side surface of each rotating rod 604. The other end of each third spring 606 is fixedly connected to the outer wall of the collar 602. A fourth spring 607 is provided on both sides of the upper surface of the annular sleeve 601. The two ends of each fourth spring 607 are fixedly connected to the upper surface of the annular sleeve 601 and the bottom surface of the partition 101, respectively. The annular sleeve 601 is slidably connected to the outer cover 1 through a pressing and limiting mechanism.

[0027] When the annular sleeve 601 is lowered by the pressing and limiting mechanism, several axially distributed flattening and degassing rollers 605 will gradually contact the upper surface of the suction cup 5. As the annular sleeve 601 continues to press down, each flattening and degassing roller 605 will roll outward from the axis near the suction cup 5 to help expel the air inside the suction cup 5 and improve the adsorption stability. When the annular sleeve 601 is lowered to the bottom and limited by the pressing and limiting mechanism, the positions of several flattening and degassing rollers 605 are located around the upper surface of the suction cup 5 to enhance the flatness of the suction cup 5 during the adsorption of slices and improve the adsorption stability.

[0028] Furthermore, the pressing and limiting mechanism includes an extension 608 integrally disposed on the side wall of the annular sleeve plate 601. One end of the extension 608 is rotatably connected to one end of a toggle rod 609. The other end of the toggle rod 609 extends to the outside of the outer cover 1 through an extension groove 610 opened on the inner wall of one side of the outer cover 1. The bottom end of the extension groove 610 is located on the inner wall of one side of the outer cover 1 and is also connected to a limiting groove 611.

[0029] The annular sleeve 601 can be lowered from the outside of the outer cover 1 by the lever 609 to assist the suction cup 5 in venting. When the lever 609 is lowered to the bottom of the extension groove 610, it can be rotated to one side to enter the limiting groove 611, thereby limiting the annular sleeve 601 and ensuring the stability of the adsorption slicing process.

[0030] Furthermore, the width between the inner walls on both sides of the extension groove 610 is the same as the width of the actuating rod 609, and the width between the inner walls on the upper and lower sides of the limiting groove 611 is the same as the thickness of the actuating rod 609.

[0031] The lever 609 cannot wobble left or right in the extension groove 610, nor can it move up or down in the limiting groove 611, thereby improving the stability during adjustment and limiting.

[0032] Please see Figure 1 The outer cover 1 is made of transparent material, and the bottom opening edge is edged with rubber.

[0033] The transparent outer cover 1 allows users to easily observe the condition of the slice inside the outer cover 1 when grasping the slice, and makes it convenient to adjust the position of the suction cup 5 to ensure the accuracy of adsorption. At the same time, the rubber edging at the bottom opening of the outer cover 1 can reduce the damage to the slice when the bottom edge accidentally touches the slice.

[0034] Working principle: When a slice needs to be gripped and transported, the user presses down the pressing plate 3, which compresses the guide telescopic rod 102, causing the sealing plug 4 to descend. After the sealing plug 4 is inserted into the top of the connecting tube 2, the top of the connecting tube 2 is sealed. Then, the pressing plate 3 moves down, causing the connecting tube 2 to continue to descend, pressing the suction cup 5 flat onto the slice surface. During the deformation of the suction cup 5 and as the sealing plug 4 is inserted into the top of the connecting tube 2, some air is expelled from the connecting tube 2 and the inside of the suction cup 5, creating a pressure difference with the outside. This causes the suction cup 5 to adhere to the slice surface, completing the gripping of the slice. When it is time to put the slice down, the user releases the pressure. When the pressing plate 3 is opened, it moves upward and resets under the action of the first spring 103. After the sealing plug 4 is disconnected from the top of the connecting tube 2, air enters the interior of the connecting tube 2, thereby equalizing the internal and external pressure difference. The suction cup 5 then detaches from the slice. By setting the suction cup 5 at one end of the connecting tube 2 and switching between the sealed and unobstructed states of the connecting tube 2 through the connecting sealing plug 4, the suction cup 5 can detach from the slice without applying external force after adsorbing it. This further improves the safety and convenience of the slice transfer process and reduces the limitations caused by the difficulty of the slice detaching from the suction cup.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
