[0001] The utility model relates to the technical field of auxiliary blood collection, in particular to a portable bedside blood culture quantitative collection auxiliary base. Background Art

[0002] Currently, collecting blood culture specimens is a common nursing procedure for nurses in clinical nursing. However, when patients are admitted to the hospital for blood culture specimen collection, nurses often struggle to accurately collect the required amount of blood due to the shaking during the blood collection process. To address this, the collection bottles are placed vertically on a sample rack to improve stability. However, the height of the bed or bedside cabinet is limited, requiring medical staff to bend or squat to read the volume, which is inconvenient.

[0003] By tilting the collection bottle on an auxiliary base and presetting the standard line based on commonly used bottle sizes, the volume can be quickly and intuitively read. However, for some uncommon bottle sizes, using the standard line to read the volume can lead to inaccurate results. To address this issue, a portable bedside blood culture quantitative collection auxiliary base has been developed. Utility Model Content

[0039] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Example 1

[0041] Currently, there is a problem in the process of quantitative collection of blood culture that the sampling bottle shakes and the required amount of blood cannot be accurately collected. This embodiment provides a portable bedside blood culture quantitative collection auxiliary base, such as Figures 1-6 As shown, it includes a base plate 1, on which a support 2 with an inclined surface is fixed. The support 2 is an inverted V-shaped structure. The support 2 is provided with a plurality of storage members for temporarily placing the collection bottles. The plurality of storage members are arranged side by side on the same side (refer to Figure 1 ) or contralateral staggered discharge (reference Figure 6 Before formal blood collection, a corresponding number of collection bottles are placed in the storage unit, and then the auxiliary base is placed next to the bed or on the bedside cabinet to collect blood samples. The auxiliary base supports and limits the collection bottles, reducing shaking during blood collection and improving the stability of the collection bottles when placed, which is conducive to the subsequent accurate reading of the blood sample volume. Moreover, when collecting blood, medical staff do not need to bend down or squat to read the volume, which simplifies the operation.

[0042] In this embodiment, the storage member includes a connecting plate 3 fixed to a support 2. A storage tube 4 is fixed to the connecting plate 3. A reference line 5 is provided on the side of the notch of the storage tube 4. The reference line 5 is pre-calculated based on the tilt angle to ensure that the reading of a tilted collection bottle is the same as when it is placed upright and viewed horizontally. Two sets of limit plates 6 are symmetrically arranged within the storage tube 4. The limit plates 6 are curved and conform to the surface of the collection bottle, providing a stable clamp and further improving stability. The storage tube 4 is also equipped with an adjustment mechanism 11 for controlling the movement of the two sets of limit plates 6. After the collection bottle is placed in the storage tube 4, the limit plates 6 are used to clamp it, improving its stability during blood collection. The blood sample volume in the collection bottle can then be read according to the reference line 5 until the desired amount is reached. This ensures that the collection bottle is stable and allows for accurate blood volume readings, which is relatively simple and convenient. The reference line 5 is set based on the specifications of commonly used collection bottles.

[0043] However, when faced with collection bottles of different sizes (diameters), the standard line 5 planned and set in advance cannot be well adapted, resulting in inaccurate readings. For this reason, a pressure sensor 7 is installed on the connecting plate 3. Of course, the pressure sensor 7 can also be installed on the support 2, or at the position where the support 2 and the base plate 1 are connected. An alarm 8 adapted for use with the pressure sensor 7 is installed on the support 2. When the blood sample in the collection bottle reaches the required amount, the pressure sensor 7 transmits a signal to the alarm 8 after reaching a specific pressure. The alarm 8 sounds, and blood collection is stopped. Compared with only using the standard line 5, it can adapt to collection bottles of various diameters, thereby improving practicality.

[0044] For collection bottles of different diameters, the spacing between the two sets of limit plates 6 after clamping varies. The adjustment mechanism 11 comprises a telescopic rod 111 secured between the limit plates 6 and the storage tube 4. A spring 112 is sleeved around the rod 111. To place a collection bottle, simply insert the end of the bottle between the two sets of limit plates 6, where the spring 12 acts to clamp and retain it in place, making operation simple and convenient.

[0045] Furthermore, a plurality of groups of outwardly curved guide pieces 10 are fixed to the end of the limiting plate 6 near the open end of the storage tube 4. The selection of the guide piece 10 is to allow the collection bottle to be smoothly and quickly inserted between the two groups of limiting plates 6.

[0046] In this embodiment, a plurality of groups of suction cups 9 are installed at the end of the bottom plate 1 away from the support 2. The provision of the suction cups 9 improves the stability of the bottom plate 1 when placed, and can prevent the shaking of the auxiliary base caused by the shaking of the blood drawing hose.

[0047] Example 2

[0048] refer to Figure 7-Figure 9The embodiment is substantially the same as Example 1, differing in that the adjustment mechanism 12 comprises a housing 121 fixed to the end of the storage tube 4 and two sets of guide slideways 124 provided on the storage tube 4. A bidirectional screw rod 122 is rotatably mounted on the housing 121. One end of the bidirectional screw rod 122 extends out of the housing 121 and is secured to a knob, allowing medical personnel to rotate the bidirectional screw rod 122 by turning the knob. A movable rod 123, fixed to the corresponding limit plate 6, is symmetrically threadedly mounted on the bidirectional screw rod 122. The movable rod 123 passes through the corresponding guide slideway 124.

[0049] The adjustment mechanism 11 in Example 1, due to its non-adjustable elastic force, employs a rigid insertion method, which poses a risk of wear and tear on the collection bottle or even causing it to break. The adjustment mechanism 12 effectively addresses this issue. During use, the collection bottle is placed between the two sets of limit plates 6. Rotating the bidirectional screw 122 simultaneously drives the two sets of movable rods 123 and the limit plates 6 thereon to move inward, thereby clamping the collection bottle and effectively preventing wear and tear on the collection bottle.

[0050] Example 3

[0051] refer to Figure 10-12 The embodiment is substantially the same as that of Example 1, with the difference that the adjustment mechanism 13 includes two sets of through-holes 131 formed in the storage tube 4, and two sets of support rods 132 fixed to corresponding limiting plates 6. The support rods 132 pass through the corresponding through-holes 131, and are fixed to the support rods 132 with spring plates 133 for use with the through-holes 131. When the spacing between the limiting plates 6 needs to be adjusted to clamp collection bottles of different specifications and sizes, the two sets of spring plates 133 are simply pressed to separate them from the inner walls of the through-holes 131, thereby moving the support rods 132 and the limiting plates 6 thereon. After contacting the collection bottle, the spring plates 133 are released, causing them to expand outward and re-tighten against the inner walls of the through-holes, thereby achieving stable clamping of the collection bottle.

[0052] Example 4

[0053] Based on Example 1, Figure 13 The bottom plate 1 has symmetrically formed receiving slots 15 at the ends facing away from the support 2. A support frame 16 is rotatably mounted within the receiving slot 15. Because lancets are relatively short, placing the auxiliary base near a bed can sometimes hinder smooth blood collection due to the limited needle length. In this case, the support frames 16 on both sides are flipped so that they contact the bedside, raising the storage barrel 4 and the collection bottle within it, shortening the distance to the subject, ensuring smooth blood collection within the lancet's length range and improving practicality.

[0054] Example 5

[0055] Based on Example 1, Figure 14The storage tube 4 has a standard rod 17 slidably mounted in its notch. A locking screw 18 is provided on the standard rod 17, and the position of the standard rod 17 can be adjusted by turning the locking screw 18. Setting only the standard line 5 requires medical personnel to carefully read the required blood volume, which is difficult in dim lighting. Therefore, the standard rod 17 is provided and can be moved to the lowest standard line 5 of the required blood volume according to the size of the collection bottle. When the lowest point of the blood sample in the collection bottle exceeds the standard rod 17, it indicates that the minimum blood collection requirement has been met. This eliminates the need for medical personnel to carefully monitor the standard line 5, making it more convenient to use.

[0056] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
