Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blood culture and blood collection auxiliary device. Background Technology

[0002] Blood culture is one of the most important tests in clinical microbiology laboratories. It involves drawing blood from the patient and placing it in a bottle containing culture medium to determine whether the microorganisms (bacteria or fungi) causing the infection have invaded the bloodstream. It is the gold standard for diagnosing bloodstream infections and bacteremia. To more accurately determine the presence of a bloodstream infection, blood culture collection must meet certain standards. The amount of blood collected is the most important factor affecting the positive rate of blood cultures. To improve the detection rate of pathogens and reduce testing errors, bilateral sampling is generally performed, with two bottles on each side (aerobic bottle + anaerobic bottle). Based on the preliminary diagnosis, a fungal bottle may also be collected simultaneously. The blood volume in each culture bottle should be controlled between 8-10 ml; too much or too little blood is prohibited. When the blood volume in each bottle is less than 5 ml, false negatives or delayed microbial growth may occur. When the blood volume in each bottle exceeds 10 ml, false positives may occur due to the large amount of CO2 produced by the metabolism of leukocytes themselves.

[0003] Currently, during clinical blood culture collection, patient positioning often changes due to their condition, making it difficult to maintain a vertical position for the blood culture bottle. In a tilted or unstable state, the culture medium may spill out, contaminating the blood vessel. Furthermore, nurses may find it difficult to accurately control the amount of blood collected, resulting in either too little or too much sample. All of these factors can affect the results and interpretation of the blood culture. Utility Model Content

[0004] The purpose of this invention is to provide a blood collection auxiliary device that helps blood collection personnel achieve accurate blood collection volume.

[0005] To achieve the above objectives, this utility model proposes a blood culture blood collection auxiliary device, including a base, a storage compartment, and a clamping mechanism; the storage compartment is disposed on the base, and both ends of the clamping mechanism are placed inside the storage compartment via movable shafts;

[0006] The clamping mechanism has multiple storage holes on its surface, and elastic clamps are provided on the side walls of the storage holes; a through-beam sensor is provided inside the storage compartment.

[0007] Furthermore, the bottom of the storage compartment is connected to the surface of the base via a telescopic rod.

[0008] Furthermore, the clamping mechanism is a long strip structure with a rotating shaft at each end. One rotating shaft is inserted into and fixed to the inner wall of one side of the storage compartment and then movably connected; the other rotating shaft passes through the side wall of the other side of the storage compartment and is movably connected to a fixed block on the outer surface of the storage compartment. A roller is sleeved on the outer surface of the rotating shaft and is located inside the fixed block.

[0009] Furthermore, the fixing block is fixed to the outer wall of the storage compartment.

[0010] Furthermore, the elastic clamp includes two clamping plates arranged opposite each other; the side wall of the storage hole is provided with two mounting slots arranged opposite each other, and the two clamping plates are fixed in the mounting slots by springs.

[0011] Furthermore, the through-beam sensor includes a light emitter located on the inner wall of one side of the storage compartment and a receiver located on the inner wall of the other side of the storage compartment.

[0012] The transparent blood collection container is inserted into the storage hole, with the bottom of the transparent blood collection container placed at the bottom of the storage compartment. The light emitter and receiver are positioned at the 8mL mark on the transparent blood collection container.

[0013] Compared with existing technologies, the advantages of this invention are as follows: The clamping mechanism of the blood collection auxiliary device can be rotated and adjusted, allowing manual adjustment of the transparent blood collection container to a vertical position. The tilted placement of the transparent blood collection container leads to inaccurate markings, affecting the blood collection volume. Furthermore, a through-beam sensor monitors the blood collection volume inside the container, issuing a warning and ensuring the blood collection volume remains within the optimal range.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0020] like Figure 1 As shown, this utility model proposes a blood culture blood collection auxiliary device, including a base 1, a storage compartment 3 and a clamping mechanism 303; the storage compartment 3 is connected to the base 1 by a telescopic rod 4, and the height of the storage compartment 3 can be adjusted by adjusting the telescopic rod 4.

[0021] In this embodiment, as Figure 2 and Figure 3 As shown, the clamping mechanism 303 is a long strip structure with a rotating shaft 302 at each end. The rotating shaft 302 at one end is inserted into and fixed to the inner wall of one side of the storage compartment 3 and then movably connected. The rotating shaft 302 at the other end passes through the side wall of the other side of the storage compartment 3 and is movably connected to the fixing block 307 on the outer surface of the storage compartment 3. A roller 308 is sleeved on the outer surface of the rotating shaft 302 and is located inside the fixing block 307. The fixing block 307 is fixed to the outer wall of the storage compartment 3.

[0022] In this embodiment, as Figure 3 and Figure 4 As shown, the surface of the clamping mechanism 303 is provided with multiple storage holes 304, and the sidewalls of the storage holes 304 are provided with elastic clamps; specifically, as shown... Figure 5 As shown, the elastic clamp includes two clamping plates 306 arranged opposite to each other; the side wall of the storage hole 304 is provided with two mounting grooves arranged opposite to each other, and the two clamping plates 306 are fixed in the mounting grooves by springs 305.

[0023] In this embodiment, a beam sensor is provided inside the storage compartment 3. The beam sensor includes a light emitter located on one inner wall of the storage compartment 3 and a receiver located on the other inner wall of the storage compartment 3. A transparent blood collection container is inserted into the storage hole 304, with the bottom of the transparent blood collection container placed at the bottom of the storage compartment 3. The light emitter and receiver are positioned at the 8mL mark on the transparent blood collection container. The beam sensor can be connected to an external alarm device, such as a buzzer or a computer. When the blood volume inside the transparent blood collection container reaches 8mL, the signal transmission between the light emitter and receiver is blocked, triggering an alarm.

[0024] In this embodiment, the working principle of this utility model is as follows: The blood collection personnel insert the transparent blood collection container into the storage hole 304 of the clamping mechanism 303 until the bottom of the transparent blood collection container contacts the bottom of the storage compartment 3. At this time, the elastic clamps on both sides of the storage hole 304 clamp the transparent blood collection container. Rotate the roller 308 to adjust the angle of the clamping mechanism 303 so that the transparent blood collection container is in a vertical state, avoiding the tilt of the collected blood inside from affecting the reading. After the angle is adjusted, blood is collected. When the blood collection volume reaches the 8mL mark of the transparent blood collection container, the signal reception of the through-beam sensor is blocked, triggering the alarm system. At this time, blood collection is stopped immediately, which can make the blood collection volume at the ideal blood collection volume of 8-10mL, which is convenient for subsequent analysis and culture.

[0025] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
