Description

Technical Field

[0001] The utility model relates to the technical field of blood collection nursing, in particular to a blood collection tube placement rack. Background Art

[0002] During intravenous preparation center care, blood needs to be drawn and stored in blood collection tubes. The blood collection tubes are divided into specifications such as φ13x75, φ13x100, φ16x100, and φ9x120mm according to the amount of blood collected. That is, the blood collection tubes are divided into specifications such as diameters of 13mm, 16mm, and 9mm. Therefore, blood collection tube racks of corresponding sizes are generally required for aligning and fixing.

[0003] In the prior art, a patent with publication number CN 217288508 U discloses a blood collection tube placement rack for intravenous preparation center care, comprising a vertical partition and a blood collection tube placement rack body fixedly installed on both sides of the vertical partition, and the blood collection tube placement rack body is provided with a plurality of test tube placement holes, a fixed suction cup is fixedly connected to the bottom of the vertical partition, a cavity is provided inside the vertical partition, a trachea is provided in the cavity, and the bottom end of the trachea extends to the inside of the fixed suction cup; a negative pressure airbag is fixedly connected to the top center of the vertical partition. Although the blood collection tube placement rack for intravenous preparation center care uses an air tube to perform negative pressure suction in the fixed suction cup and can fix the blood collection tube placement rack on the blood collection workbench, the test tube placement hole size of the blood collection tube placement rack for intravenous preparation center care is fixed and is only suitable for the placement of a single type of test tube. When the blood collection process requires the use of multiple types of test tubes, it is not convenient to place blood collection tubes of different diameters. In addition, because the placement rack only limits and fixes the blood collection tubes through the test tube placement hole, during the transfer of the blood collection tube placement rack, the blood collection tubes are easily damaged by shaking in the test tube placement hole due to their own inertia.

[0004] In view of this, it is necessary to design a blood collection tube placement rack to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a blood collection tube placement rack which can keep the blood collection tube and the placement rack relatively fixed, thereby avoiding damage to the tube body caused by the shaking of the blood collection tube during the transfer process, and can also meet the placement requirements of multiple types of blood collection tubes.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A blood collection tube placement rack, comprising:

[0008] A placing rack body, wherein a placing plate is arranged on the placing rack body, and a plurality of first holes for blood collection tubes to pass through are arranged on the placing plate;

[0009] A fixing plate, arranged on the placing rack body, the fixing plate is provided with a plurality of second holes corresponding to the first holes, and a cavity communicating with the second holes is arranged inside the fixing plate;

[0010] The limiting structure is located in the cavity and includes a limiting plate and a control component for controlling the horizontal movement of the limiting plate. The limiting plate is provided with a plurality of plate bodies corresponding to the second holes, so that when the control component controls the limiting plate to move horizontally, the plurality of plate bodies respectively form clamping spaces of different sizes for fixing the blood collection tubes with the corresponding side walls of the second holes.

[0011] As a further improvement of the present invention, the control assembly includes a rod body installed on the side of the limit plate away from the plate body and an elastic member that provides a fastening force for the fixation of the blood collection tube. The rod body extends to the outside of the fixed plate at one end away from the plate body and is movably connected to the fixed plate, so that the rod body can move in a direction perpendicular to the side wall of the fixed plate.

[0012] As a further improvement of the present invention, the elastic member is a spring, the spring is sleeved on the rod body, and two ends of the spring are respectively connected to the limiting plate and the side wall of the fixing plate.

[0013] As a further improvement of the utility model, one end of the rod body extending outside the fixing plate is connected to a hand piece.

[0014] As a further improvement of the utility model, a handle is also provided on the placing rack body to facilitate the overall movement of the placing rack.

[0015] As a further improvement of the utility model, the placement plates are arranged in two layers at intervals along the vertical direction.

[0016] As a further improvement of the utility model, the fixing plate is located between two layers of placement plates and is parallel to the placement plates.

[0017] As a further improvement of the present invention, the bottom surface of the rack body is further provided with a plurality of support ears for increasing the force-bearing area of ​​the bottom surface of the rack body.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model controls the limit plate to move in the cavity of the fixed plate in the horizontal direction through the control component, so that the plate body on the limit plate and the corresponding second hole form clamping spaces of different sizes, which can clamp and fix blood collection tubes of different sizes. While solving the problem that the existing blood collection tube placement rack is only suitable for placing a single type of test tube, it also solves the problem that the blood collection tube will shake in the test tube placement hole due to its own inertia and be easily damaged during the transfer process of the existing blood collection tube placement rack.

[0020] 2. The utility model utilizes a control component to simultaneously clamp and regulate the blood collection tubes on the same row of placement holes, so that when the blood collection tubes need to be transferred, all the blood collection tubes in the same row can be released by pulling open the rod body with one hand, thereby facilitating the sequential transfer of all the blood collection tubes in the same row. Compared with the prior art in which an independent control structure is provided for each placement hole to fix the blood collection tubes, so that each control structure needs to be operated sequentially when transferring the blood collection tubes, the operation is simpler and the transfer efficiency of the blood collection tubes can be effectively improved.

[0021] 3. The design of independently arranging a fixing plate on the placement rack of the utility model is applicable to a placement rack with a single row of holes or a placement rack with more than two rows. For example, for a placement rack with three or more rows of placement holes, by extending the rod body corresponding to the middle placement hole and staggering the middle rod body with other rod bodies in the horizontal direction, and staggering different fixing plates in the vertical direction, the clamping and fixing requirements of all blood collection tubes placed on the placement rack can be met.

[0034] See also Figure 1-Figure 4 As shown, the utility model provides a blood collection tube placement rack, comprising:

[0035] A placing rack body, wherein a placing plate is arranged on the placing rack body, and a plurality of first holes for blood collection tubes to pass through are arranged on the placing plate;

[0036] A fixing plate 30 is disposed on the placing rack body, and a plurality of second holes 31 corresponding to the first holes are disposed on the fixing plate 30, and a cavity 32 communicating with the second holes 31 is disposed inside the fixing plate 30;

[0037] The limiting structure is located in the cavity 32, and includes a limiting plate 41 and a control component for controlling the horizontal movement of the limiting plate 41. The limiting plate 41 is provided with a plurality of plate bodies 42 corresponding to the second holes 31, so that when the control component controls the limiting plate 41 to move horizontally, the plurality of plate bodies 42 respectively form clamping spaces of different sizes with the corresponding side walls of the second holes 31, so as to clamp and fix the blood collection tubes inserted into the first holes in the same row of the placement plate at the same time.

[0038] Specifically, in this embodiment, the diameter of the second hole 31 is the same as the diameter of the first hole.

[0039] Specifically, the placing rack body includes a bottom plate 11 and vertical plates 12 arranged on both sides of the bottom plate 11; the placing plate is arranged between the two vertical plates 12, and along the vertical direction, the placing plate is arranged with two layers, including a first rectangular plate 21 and a second rectangular plate 22, a plurality of first placing holes 211 are arranged at intervals on the first rectangular plate 21 in a direction perpendicular to the vertical plate 12, and a plurality of second placing holes 221 are arranged on the second rectangular plate 22 in a direction perpendicular to the vertical plate 12. In this embodiment, a partition 50 is further arranged in a direction perpendicular to the vertical plate 12, and the first rectangular plate 21 and the second rectangular plate 22 are arranged on both sides of the partition 50, respectively, and a handle 60 is installed on the top of the partition 50 to facilitate the overall movement of the placing rack.

[0040] Specifically, the fixed plate 30 is arranged parallel to the placing plate, and its two ends are respectively connected to the two vertical plates 12, and along the vertical direction, the fixed plate 30 is located between the first rectangular plate 21 and the second rectangular plate 22. In this embodiment, fixed plates 30 are arranged on both sides of the partition 50, and a through hole 33 is also arranged on the side of the fixed plate 30 away from the partition 50.

[0041] Specifically, Figure 4 and Figure 5 As shown, the control assembly includes a rod body 44 installed on the side of the limit plate 41 away from the plate body 42 and an elastic member that provides a fastening force for fixing the blood collection tube. The end of the rod body 44 away from the plate body 42 extends to the outside of the fixed plate 30 through the through hole 33, and the size of the through hole 33 is larger than the size of the rod body 44, so that the rod body 44 can move in a direction perpendicular to the side wall of the fixed plate 30; in this embodiment, the elastic member is a spring 43, which is sleeved on the rod body 44, and the two ends are respectively connected to the limit plate 41 and the fixed plate 3 0 side walls, so that under the force, the rod body 44 moves in the direction away from the second hole 31 to drive the limit plate 41 to move, compressing the spring 43, and clamping spaces of different sizes are formed between the plate body 42 and the side wall of the second hole 31. When the blood sampling tube is sequentially passed through the first placement hole 211, the second hole 31 and the second placement hole 221 and placed on the placement rack, the force is removed. Under the rebound force of the spring 43, the plate body 42 and the side wall of the second hole 31 clamp the blood sampling tube and fix the blood sampling tube on the placement rack.

[0042] The limiting structure is used to simultaneously fix the blood collection tubes in the same row of placement holes of the placement rack, that is, when the rod body 44 drives the limiting plate 41 to move, all the plates 42 form a clamping space of the same size with the corresponding second hole 31, and the size of the clamping space is adjusted by adjusting the position of the plate body 42 relative to the second hole 31, so that the placement rack can adapt to blood collection tubes of different specifications, that is, under the clamping effect of the plate body 42 and the side wall of the second hole 31, the blood collection tubes in the same row of placement holes can be relatively fixed with the placement rack, so that the placement rack can meet the placement requirements of different types of blood collection tubes. When it is necessary to transfer the blood collection tubes, the adjustment rod body 44 is moved away from the second hole 31 until the plate body 42 is away from the side wall of the blood collection tube, and the clamping of all the blood collection tubes in the row of placement holes can be released at the same time, which is convenient for the transfer of the blood collection tubes in sequence.

[0043] By setting the limiting structure in the cavity of the fixed plate 30 and passing the rod body 44 through the through hole 33 on one side of the fixed plate 30, it is convenient to control the movement of the limiting plate 41 in the cavity 32, and at the same time, the fixed plate 30 can be used to provide support force for the limiting structure. For example, a slide groove can be set in the cavity 32, and a slider matching the slide groove can be set on the limiting plate 41 to improve the stability of the movement of the limiting plate 41 (not shown in the figure).

[0044] In other embodiments, the elastic member can also be set as an elastic layer structure or a spring 43 fixed between the side of the limiting plate 41 away from the plate body 42 and the side wall of the fixing plate 30, so that when the rod body 44 moves in a direction away from the second hole 31, the elastic member is compressed, and the blood collection tube is fixed by utilizing the restoring force of the elastic member.

[0045] Specifically, the plate body 42 is an arc-shaped plate, and the curvature of the arc-shaped plate can be set according to actual application requirements.

[0046] Specifically, one end of the rod body 44 extending outside the fixing plate 30 is connected to a hand piece. In this embodiment, the hand piece is a pull ring 45 .

[0047] Specifically, the bottom surface of the bottom plate 11 is also provided with a plurality of support ears 70 for increasing the force-bearing area of ​​the bottom plate 11. Exemplarily, four support ears 70 are provided, respectively located at the four corners of the bottom plate 11, so as to enhance the stability of the placement rack.

[0048] Specifically, this embodiment is an example structure of a placement rack with two rows of placement holes. For a placement rack with three or more rows of placement holes, a placement rack with three rows of placement holes is taken as an example. Figure 6 and Figure 7As shown, the rod body 44 in the limiting structure for fixing the entire row of blood collection tubes located in the middle of the placement rack can be extended to the left side of the placement rack, and the rod body 44 in the left limiting structure and the rod body 44 in the middle limiting structure are spaced apart in the horizontal direction, and at the same time, the fixing plate 30 corresponding to the left placement hole and the fixing plate 30 corresponding to the middle placement hole are spaced apart in the vertical direction to avoid interference of the left limiting structure with the clamping and fixing adjustment of the middle limiting structure.

[0049] The working principle of the blood collection tube placement rack of the utility model is described below:

[0050] When in use, the medical staff hooks the pull ring 45 and pulls the rod body 44 in the direction away from the second hole 31. The movement of the rod body 44 drives the limiting plate 41 to move toward the side wall of the fixing plate 30 to squeeze the spring 43, and the blood collection tube passes through the first placement hole 211, the second hole 31 and the second placement hole 221 in sequence, and releases the pull ring 45. Under the restoring force of the spring 43, the limiting plate 41 moves toward the second hole 31, driving the plate body 42 to move toward the second hole 31 to push the blood collection tube to move to the blood collection tube and at the same time tightly abut against the side walls of the plate body 42 and the second hole 31, so that under the restoring force of the spring 43, the blood collection tube is clamped and fixed by using the plate body 42 and the side walls of the second hole 31; because the spring 43 can be deformed to different degrees, a clamping space for clamping and fixing blood collection tubes of different sizes can be formed between the plate body 42 and the second hole 31, so that the placement rack can be used to fix blood collection tubes of different sizes.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
