Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, specifically to a quick-assembly anti-fall bed for peripheral blood collection from infants and young children. Background Technology

[0002] Capillary blood sampling is a clinical testing procedure that involves puncturing capillaries in areas such as the fingertips or earlobes to obtain a small blood sample. It is primarily used for rapid tests such as complete blood counts and blood glucose monitoring, and is characterized by its simplicity, minimal invasiveness, and lack of need for venipuncture. Capillary blood sampling simplifies the specimen collection process, shortens patient waiting times, and improves the response speed of emergency and community healthcare facilities. Its minimally invasive nature significantly reduces anxiety and psychological stress associated with blood collection, making it particularly suitable for children and those prone to fainting at the sight of blood.

[0003] Because infants and young children's bodily functions are not yet fully developed, and their veins are very thin, making venipuncture more difficult, capillary blood collection is the preferred method for collecting blood samples. During capillary blood collection from infants and young children, parents typically place the infant on the table at the blood collection window (e.g., Figure 15 As shown in the image, blood is drawn from the fingertips or heels by medical staff. However, the existing blood collection windows have small tabletops with smooth edges, and infants are prone to involuntary limb movements due to pain during blood collection. At the same time, parents may be distracted or have limited limb coordination when assisting with the procedure, which may result in insufficient fixation of the infant, making it easy for the infant to slip during the blood collection process, leading to direct injuries such as abrasions and bumps.

[0004] Therefore, how to design a quick-assembly anti-fall bed for capillary blood collection of infants and young children that can prevent them from slipping during the blood collection process is a technical problem that has not yet been solved in the existing technology. Utility Model Content

[0010] As a preferred embodiment, the mounting base includes a mounting blade and a connecting block formed on one side of the mounting blade, wherein the axis of the connecting block forms a 90° angle with the axis of the mounting blade.

[0011] As a preferred embodiment, the other end of the U-shaped connector is rotatably mounted on the connecting block via a second rotating connection structure and is limited by a second limiting structure; the second rotating connection structure includes: a first connecting through hole, which is formed through the other end of the U-shaped connector; a second connecting through hole, which is formed through the connecting block; and a second connecting shaft, which passes through the first connecting through hole and the second connecting through hole, thereby rotatably mounting the other end of the U-shaped connector and the connecting block together.

[0012] As a preferred embodiment, the second limiting structure includes: a limiting ring integrally formed at one end of the second connecting shaft, the limiting ring being fitted against one side outer wall of the second connecting through hole; a third limiting groove formed at the other end of the second connecting shaft; and a second elastic retaining spring sleeved in the third limiting groove, cooperating with the limiting ring to rotatably limit the other end of the U-shaped connector on the mounting base.

[0013] As a preferred embodiment, the mounting blade has three through holes, which are suitable for fixing the mounting blade to the bottom of the blood collection table by passing mounting bolts through the mounting holes.

[0017] When performing capillary blood collection on infants and young children, the main plate is flipped up to the top of the blood collection table via the flip groove and U-shaped connector, ensuring that the baffle is positioned close to the parent's chest and hands. The height of the baffle confines the infant or young child within the support area of ​​the main plate, preventing them from slipping (e.g., Figure 10 (As shown); After peripheral blood collection is completed, the main body plate is flipped over via the flip groove and U-shaped connector to the patient side of the blood collection table for storage (as shown). Figure 11(As shown), wait for the next use. If the distance between the isolation glass of some hospital blood collection windows and the blood collection table is small, and the main body panel cannot be directly flipped around the U-shaped connector to the top of the blood collection table, then the U-shaped connector can be flipped to a horizontal position with the blood collection table first (e.g., Figure 12 (As shown), then pull the main body plate upwards until one end of the U-shaped connector reaches the end of the main body plate before the baffle is formed. Next, flip the main body plate towards the patient and adjust it to a horizontal position (as shown). Figure 13 (As shown), then continue to flip the U-shaped connector so that its inner wall fits against the side of the blood collection table (as shown). Figure 14 (As shown), then push the main body plate horizontally into the top of the blood collection table to perform peripheral blood collection; after peripheral blood collection is completed, reverse the operation to store the main body plate to the patient side of the blood collection table.

[0018] This utility model is a quick-assembly anti-fall bed for peripheral blood collection from infants and young children. The baffle on the main plate can physically limit the movement of the infants' limbs and reduce the risk of slipping. In addition, the flexible cooperation between the U-shaped connector and the main plate enables it to be adapted to blood collection windows of different sizes, thus improving the applicability of the device.

[0040] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0041] This embodiment provides a quick-assembly anti-fall bed for capillary blood collection from infants and young children, such as... Figure 1-3As shown, the device includes a main body plate 1, a U-shaped connector 22, and a mounting base 23. The main body plate 1 is adapted to be rotatably mounted on the top of the blood collection table, and has rotatable grooves 21 on both sides. Baffles 11 are formed on the top surface of the rotatable grooves 21 and the top surface facing the patient on the main body plate 1. There are two U-shaped connectors 22, one end of which is connected to the rotatable groove 21 through a first rotating connection structure, so that the main body plate 1 can be rotated around the U-shaped connector 22 through the rotatable groove 21. The mounting base 23 is adapted to be fixedly mounted on the bottom of the blood collection table, and the other end of the U-shaped connector 22 is rotatably mounted on the mounting base 23.

[0042] When performing capillary blood collection on infants and young children, the main body plate 1 is flipped up to the top of the blood collection table 01 via the flipping groove 21 and the U-shaped connector 22, ensuring that the baffle 11 is positioned close to the parent's chest and left and right hands. The height of the baffle 11 is used to confine the infant or young child within the bearing area of ​​the main body plate 1, preventing them from slipping (e.g., Figure 10 (As shown); After peripheral blood collection is completed, the main body plate 1 is flipped around the U-shaped connector 22 via the flipping groove 21 and stored on the patient side of the blood collection table 01 (as shown). Figure 11 (As shown), waiting for the next use. If the distance between the isolation glass 02 and the blood collection table 01 of some hospital blood collection windows is small, and the main body plate 1 cannot be directly flipped around the U-shaped connector 22 to the top of the blood collection table 01, then the U-shaped connector 22 can be flipped to a horizontal position with the blood collection table 01 first (as shown). Figure 12 (As shown), then pull the main body plate 1 upwards until one end of the U-shaped connector 22 reaches the end of the main body plate 1 without the baffle 11. Then flip the main body plate 1 towards the patient and adjust it to a horizontal position (as shown). Figure 13 (As shown), then continue to flip the U-shaped connector 22 so that its inner wall fits against the side of the blood collection table 01 (as shown). Figure 14 As shown in the diagram, the main body plate 1 is then pushed horizontally into the top of the blood collection table 01 to perform capillary blood collection. After capillary blood collection is completed, the main body plate 1 can be stored on the patient side of the blood collection table 01 by reversing the operation. This embodiment is a quick-assembly anti-fall bed for capillary blood collection in infants and young children. The baffle 11 on the main body plate 1 can physically limit the movement of the infant's limbs and reduce the risk of slipping. In addition, the flexible cooperation between the U-shaped connector 22 and the main body plate 1 enables adaptation to blood collection windows of different sizes, improving the applicability of the device.

[0043] like Figure 4As shown, the first rotating connection structure includes a first connecting shaft 31 and a side opening 32. One end of the first connecting shaft 31 is movably mounted on one end of the U-shaped connector 22 via a limiting installation structure. The side opening 32 is formed on both sides of the flip groove 21, and the other end of the first connecting shaft 31 is mounted in the flip groove 21 through the side opening 32 and is limited by the first limiting structure, thereby allowing the main body plate 1 to flip around the first connecting shaft 31 via the flip groove 21. Through the cooperation of the first connecting shaft 31 and the flip groove 21, a connection that is both rotatable and slidable between the main body plate 1 and the U-shaped connector is achieved, providing a structural basis for the flipping and position adjustment of the main body plate 1 and ensuring flexible operation in different scenarios.

[0044] The limiting installation structure includes an oblong hole 41, a first limiting groove 42, a first elastic retaining spring 43, and an annular flange 44; wherein the oblong hole 41 is formed through one end of the U-shaped connector 22, and one end of the first connecting shaft 31 is movably installed in the oblong hole 41; the annular flange 44 is formed in the middle of the first connecting shaft 31, and one side of the outer wall of the oblong hole 41 is attached to the annular flange 44; the first limiting groove 42 is formed near one end of the first connecting shaft 31; the first elastic retaining spring 43 is sleeved in the first limiting groove 42, which can limit the first connecting shaft 31 to be installed on the U-shaped connector 22. The waist-shaped hole 41 provides room for the first connecting shaft 31 to move when the U-shaped connector 22 is flipped. By adjusting the position of the first connecting shaft 31 in the waist-shaped hole 41, the main body plate 1 can be pressed into place and fit against the table after it is in place, so as to avoid the use affected by tilting. The annular flange 44 cooperates with the first elastic retaining spring 43 to limit the first connecting shaft 31 and prevent it from detaching from the waist-shaped hole 41, thus ensuring the stability of the connection.

[0045] The first limiting structure includes a second limiting groove 51, a limiting plate 52, threaded blind holes, and limiting screws 53. The second limiting groove 51 is located near the other end of the first connecting shaft 31. A pair of limiting plates 52 are integrally formed on the two long sides of the flip groove 21 and extend towards each other. The limiting plates 52 are matched and installed with the second limiting groove 51 and can be flipped around the second limiting groove 51. Two threaded blind holes are located at the side opening 32. Two limiting screws 53 are screwed into the threaded blind holes, thereby limiting one end of the first connecting shaft 31 within the flip groove 21. The second limiting groove 51 can slide along the edge of the limiting plate 52, allowing the other end of the first connecting shaft 31 to move axially along the flip groove 21.

[0046] The mounting base 23 includes a mounting blade 232 and a connecting block 233 formed on one side of the mounting blade 232. The axis of the connecting block 233 forms a 90° angle with the axis of the mounting blade 232. The 90° angle design allows the mounting blade 232 and the connecting block 233 to be adapted to the mounting surface at the bottom of the blood collection table 01 and the rotation direction of the U-shaped connector, respectively, facilitating stable installation and flexible connection of the mounting base 23 within a limited space.

[0047] The other end of the U-shaped connector 22 is rotatably mounted on the connecting block 233 via a second rotating connection structure and is limited by a second limiting structure. The second rotating connection structure includes a first connecting through hole 71, a second connecting through hole 72, and a second connecting shaft 73. The first connecting through hole 71 is formed through the other end of the U-shaped connector 22. The second connecting through hole 72 is formed through the connecting block 233. The second connecting shaft 73 passes through the first connecting through hole 71 and the second connecting through hole 72, thereby rotatably mounting the other end of the U-shaped connector 22 and the connecting block 233 together.

[0048] The second limiting structure includes a limiting ring 74, a third limiting groove 75, and a second elastic retaining spring 76; wherein the limiting ring 74 is integrally formed on one end of the second connecting shaft 73, and the limiting ring 74 fits against one side outer wall of the second connecting through hole 72; the third limiting groove 75 is opened at the other end of the second connecting shaft 73; the second elastic retaining spring 76 is sleeved in the third limiting groove 75 and cooperates with the limiting ring 74 to rotatably limit the other end of the U-shaped connector 22 on the mounting base 23.

[0049] The mounting blade 232 has three through holes 231, which are suitable for fixing the mounting blade 232 to the bottom of the blood collection table using mounting bolts passing through the through holes 231. The three through holes 231 can enhance the connection strength between the mounting blade 232 and the bottom of the blood collection table 01, making the mounting base 23 more stable and reducing shaking during use.

[0050] like Figure 5-9 As shown, the main body plate 1 can be fixedly installed on the top of the blood collection table via a fixing structure 6; the fixing structure 6 includes an elastic band 62, a fixing claw 63, a fixing groove 64, and a lifting handle 65; wherein one end of the elastic band 62 is fixedly installed on the main body plate 1; the fixing claw 63 is fixedly disposed at the other end of the elastic band 62, located on the outside of the main body plate 1; the lifting handle 65 is integrally formed on the fixing claw 63; the fixing groove 64 is adapted to be opened on the side of the blood collection table away from the patient; the fixing claw 63 is adapted to engage with the fixing groove 64, thereby fixing the main body plate 1 on the top of the blood collection table.

[0051] The elastic band 62 is fixedly mounted on the main body plate 1 by a mounting structure. The mounting structure includes a mounting cavity 61, a fixing through hole 69, a fixing opening 67, and a fixing bolt 68. The mounting cavity 61 is located on the side of the main body plate 1 away from the patient, and one end has a mounting opening 66, through which one end of the elastic band 62 can extend into the mounting cavity 61. The fixing through hole 69 penetrates the portion of the elastic band 62 located in the mounting cavity 61. The fixing opening 67 is located at the bottom of the main body plate 1, communicates with the mounting cavity 61, and is vertically opposite to the fixing through hole 69. The fixing bolt 68 passes through the fixing opening 67 and the fixing through hole 69 and is screwed onto the main body plate 1, thereby fixing one end of the elastic band 62 in the mounting cavity 61. In use, pinch the lifting handle 65 and pull it outwards to pull the fixing claw 63 and the elastic band 62 it is bonded to out of the mounting cavity 61. Then, engage the fixing claw 63 in the fixing groove 64. At this time, the elastic band 62 will exert a downward pressure on the main body plate 1, thereby fixing the main body plate 1 to the top of the blood collection table. The elasticity of the elastic band 62 can adapt to the connection requirements of different table widths; the engagement of the fixing claw 63 and the fixing groove 64 can firmly fix the main body plate 1 to the top of the blood collection table 01, preventing the main body plate 1 from shifting during blood collection; the lifting handle 65 makes it convenient for medical staff to engage and disengage the fixing claw 63, improving ease of use; the mounting cavity 61 stores the elastic band 62 inside the main body plate 1, making the overall structure neater, and at the same time preventing the elastic band 62 from getting tangled with other items, improving safety during use.

[0052] In this embodiment, both the first elastic retaining ring 43 and the second elastic retaining ring 76 are shaft retaining rings manufactured by Bairuit. For details, please refer to [link / reference needed]. Figure 16 As shown.

[0053] The quick-assembly anti-fall bed for capillary blood collection from infants and young children in this embodiment is used as follows: When performing capillary blood collection on infants, the main body plate 1 is flipped up to the top of the blood collection table 01 via the flipping groove 21 and the U-shaped connector 22. Then, the main body plate 1 is pressed down through the waist-shaped hole 41 until its bottom surface is flush with the tabletop. Next, the lifting handle 65 is pinched and pulled outwards, causing the fixing claw 63 and the elastic band 62 bonded to it to be pulled out from the mounting cavity 61. Then, the fixing claw 63 is engaged in the fixing groove 64. The elastic band 62 will exert a downward force on the main body plate 1, thereby fixing the main body plate 1 to the top of the blood collection tabletop. At this time, the baffle 11 is located near the parent's chest and left and right hands. The height of the baffle 11 restricts the infant to the bearing area of ​​the main body plate 1, preventing them from slipping (e.g., Figure 10(As shown); After peripheral blood collection is completed, the fixing claw 63 is pulled out from the fixing groove 64. Then, the fixing claw 63 will automatically retract into the main body plate 1 under the pulling force of the elastic band 62. Then, the main body plate 1 is flipped around the U-shaped connector 22 through the flip groove 21 and stored on the patient side of the blood collection table 01 (as shown). Figure 11 (As shown), waiting for the next use. If the distance between the isolation glass 02 and the blood collection table 01 of some hospital blood collection windows is small, and the main body plate 1 cannot be directly flipped around the U-shaped connector 22 to the top of the blood collection table 01, then the U-shaped connector 22 can be flipped to a horizontal position with the blood collection table 01 first (as shown). Figure 12 (As shown), then pull the main body plate 1 upwards until one end of the U-shaped connector 22 reaches the end of the main body plate 1 without the baffle 11. Then flip the main body plate 1 towards the patient and adjust it to a horizontal position (as shown). Figure 13 (As shown), then continue to flip the U-shaped connector 22 so that its inner wall fits against the side of the blood collection table 01 (as shown). Figure 14 As shown), push the main body plate 1 horizontally into the top of the blood collection table 01, then press the main body plate 1 down until its bottom surface is flush with the table surface, and then engage the fixing claw 63 inside the fixing groove 64 to perform peripheral blood collection; after peripheral blood collection is completed, reverse the operation to store the main body plate 1 on the patient side of the blood collection table 01.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
