Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary device for immediate detection of sepsis specimens. Background Technology

[0002] In the clinical diagnosis and treatment of sepsis, point-of-care testing (POCT) has become a key means of early diagnosis and treatment guidance because it can quickly provide results on pathogens and inflammatory markers. Sepsis progresses rapidly and has a high mortality rate. Traditional laboratory testing procedures are time-consuming and cannot meet the needs of emergency treatment. POCT, however, can be performed at the patient's bedside or in emergency settings. Through rapid analysis of blood and body fluid samples, it can obtain key indicators such as procalcitonin, C-reactive protein, and pathogen nucleic acid within 30 minutes. This provides important information for clinicians to adjust treatment plans in a timely manner, significantly improving the treatment efficiency of sepsis patients.

[0003] The typical procedure for point-of-care testing (POCT) of sepsis specimens includes: first, collecting blood, body fluids, or other specimens from the patient and injecting them into sterile collection tubes of different sizes; then, pre-treating the specimens, such as centrifuging to separate serum or plasma, and incubating at a constant temperature to activate the reaction system; after pre-treatment, adding the specimen solution to a test strip or test card, reading the results using a portable testing instrument or visually interpreting them, and finally combining the results to formulate a treatment plan. In this procedure, the placement of specimens after collection presents significant inconveniences: due to the variety of specimen tube sizes, the lack of a dedicated fixing device easily leads to tube tipping and specimen spillage and contamination; simultaneously, manually handling specimen tubes and transferring them to different devices may result in specimen loss or cross-contamination due to improper operation. Therefore, there is an urgent need for an auxiliary device that can accommodate different tube diameters and stably fix the specimen tubes to ensure the efficiency and accuracy of the POCT process for sepsis specimens. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for the immediate detection of sepsis specimens, so as to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An auxiliary device for immediate detection of sepsis specimens includes a mounting frame with several openings on its top surface. A connecting sleeve is rotatably connected to each opening. A first adjusting plate is fixedly connected to the connecting sleeve. The top surface of the first adjusting plate has several first adjusting grooves. Several placement sleeves are fixed to the inner bottom of the mounting frame. Each placement sleeve has a placement hole at its top center. A second adjusting plate is mounted on the top surface of each placement sleeve. The top surface of the second adjusting plate has second adjusting grooves. The second adjusting plate is rotatably mounted within the connecting sleeves. The first adjusting plate is located directly above the second adjusting plate, and several fixing devices are provided between the first and second adjusting plates. The device comprises a fixed block with a first slider and a second slider mounted on its top and bottom surfaces, respectively. The first slider slides within a first adjustment groove, and the second slider slides within a second adjustment groove. Both the first and second adjustment discs have through holes at their centers. The fixed frame provides stable support for the entire device, and multiple openings allow for the simultaneous placement of multiple sets of specimens, meeting the needs of batch testing. The connecting sleeve cooperates with the first and second adjustment discs, using the sliding of the fixed block to clamp and fix specimen tubes of different specifications, preventing tipping and contamination. The placement hole of the placement sleeve provides support for the bottom of the specimen tube, and the central through hole facilitates testing operations, thereby improving the overall stability and efficiency of specimen testing.

[0007] Furthermore, several first adjustment grooves are evenly distributed circumferentially on the top surface of the first adjustment plate, the second adjustment groove has a lateral cross-section of a regular hexagon, and the fixing block has a lateral cross-section of an isosceles triangle. The number of fixing blocks is set to six. The even distribution of the first adjustment grooves circumferentially ensures that the fixing blocks are subjected to balanced force and higher synchronous adjustment accuracy. The regular hexagonal second adjustment grooves are adapted to the isosceles triangle fixing blocks. After the six fixing blocks are attached, a regular hexagonal clamping space can be formed, which can accommodate most circular specimen tubes. The clamping surface is uniform, avoiding excessive local force that could cause specimen tube damage.

[0008] Furthermore, the connecting sleeve, the first adjusting plate, the second adjusting plate, and the placement sleeve are all coaxially arranged. The coaxial arrangement ensures that the centers of each component are aligned, and the clamping force of the fixing block on the specimen tube is symmetrical along the central axis, preventing the specimen tube from tilting. At the same time, it ensures that the specimen tube is placed vertically in the placement hole, which facilitates precise operation through the central through hole and reduces operation errors.

[0009] Furthermore, the side of the opening has a first limiting ring groove, and the side of the connecting sleeve is equipped with a first limiting ring. The first limiting ring rotates within the first limiting ring groove. The side of the second adjusting disc has a second limiting ring groove, and the inner wall of the connecting sleeve is equipped with a second limiting ring near its bottom surface. The second limiting ring rotates within the second limiting ring groove. The first limiting ring and the first limiting ring groove cooperate to restrict the axial displacement of the connecting sleeve, ensuring that it can only rotate around the opening and preventing it from falling off. The second limiting ring and the second limiting ring groove cooperate to fix the axial position of the second adjusting disc, ensuring that the connecting sleeve can rotate around the second adjusting disc.

[0010] Furthermore, the first limiting ring is a rubber ring. The rubber material of the first limiting ring is elastic and fits tightly with the groove of the first limiting ring, increasing the rotational friction and preventing the connecting sleeve from rotating on its own due to external forces such as vibration, thus maintaining stable clamping force.

[0011] Furthermore, the number of placement sleeves and openings is consistent, and each opening has a corresponding placement sleeve support below it, ensuring that each specimen tube can be supported from the bottom and clamped from the side, avoiding tilting or falling due to lack of support, and adapting to the need for simultaneous testing of multiple sets of specimens.

[0012] Furthermore, a rubber pad is installed on the bottom surface of the placement hole. The rubber pad has elasticity and cushioning effect, which avoids damage caused by hard contact between the bottom of the specimen tube and the placement hole. At the same time, it increases the friction at the bottom of the specimen tube, helps to fix the specimen tube, reduces possible rotation or sliding during clamping, and improves overall stability.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This auxiliary device for immediate detection of sepsis specimens enables batch specimen processing through multiple sets of openings and placement sleeves. Utilizing the linkage structure of the first adjusting plate, the second adjusting plate, and six fixing blocks, it adapts to specimen tubes of different specifications, ensuring stable clamping. The coaxial design and limiting structure guarantee operational accuracy, while rubber pads and rubber rings enhance safety and stability. Overall, it solves the problems of unstable specimen tube fixation, easy tipping, and inconvenient operation in traditional testing methods, significantly improving the efficiency and reliability of immediate detection of sepsis specimens, making it suitable for use in emergency scenarios such as emergency rooms.

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

[0021] Please see Figure 1 - Figure 5This utility model provides a technical solution: an auxiliary device for immediate detection of sepsis specimens, including a fixing frame 1. The top surface of the fixing frame 1 has several openings 4. A connecting sleeve 2 is rotatably connected to the openings 4. A first adjusting plate 7 is fixedly connected to the connecting sleeve 2. The top surface of the first adjusting plate 7 has several first adjusting grooves 8. Several placement sleeves 3 are fixedly fixed to the inner bottom of the fixing frame 1. The center of the top surface of the placement sleeve 3 has a placement hole 15. A second adjusting plate 13 is installed on the top surface of the placement sleeve 3. The top surface of the second adjusting plate 13 has a second adjusting groove 14. The second adjusting plate 13 is rotatably installed in the connecting sleeve 2. The first adjusting plate 7 is located directly above the second adjusting plate 13. Several fixing blocks 10 are provided between the first adjusting plate 7 and the second adjusting plate 13. A first slider 11 and a second slider 12 are respectively installed on the top and bottom surfaces of the fixing blocks 10. The first slider 11 slides in the first adjusting grooves 8, and the second slider 12 slides in the first adjusting grooves 8. The first adjusting plate 7 and the second adjusting plate 13 are both provided with through holes 9 at their centers. In the immediate detection of sepsis, multiple placement holes 15 can simultaneously fix various specimen tubes such as blood and body fluids, meeting the requirements for simultaneous detection of multiple indicators such as procalcitonin and pathogen nucleic acid. Specifically, the specimen tube is placed into the placement hole 15 of the placement sleeve 3, and the connecting sleeve 2 is rotated to drive the first adjusting plate 7 to rotate synchronously. The first adjusting groove 8 pushes the fixing block 10 to move through the first slider 11. At the same time, the fixing block 10 slides in the second adjusting groove 14 through the second slider 12, so that several fixing blocks 10 contract or expand synchronously to clamp or loosen the specimen tube. The through holes 9 can be used as an operation channel to facilitate the processing of specimens during the detection process. When it is necessary to transfer to centrifuge or detection equipment, the specimen tube can be moved as a whole by directly carrying the fixing frame 1, without having to pick them up manually one by one, avoiding accidental spillage during the transfer process. Specifically, the fixing frame 1 is injection molded from ABS engineering plastic, and the bottom is equipped with anti-slip rubber pads to prevent sliding on smooth surfaces such as emergency operating tables; the diameter of the placement hole 15 and the through hole 9 is 1.5cm to 3cm, which can accommodate the placement requirements of common specimen tubes; the connecting sleeve 2 is made of polypropylene, and it is fixed to the first adjusting plate 7 by hot melt welding to ensure no relative displacement when rotating synchronously; the edges of the through hole 9 are rounded to avoid scratching the specimen tube during operation.

[0022] As an embodiment of this utility model, further, a plurality of first adjustment grooves 8 are evenly distributed circumferentially on the top surface of the first adjustment disk 7, the transverse cross section of the second adjustment groove 14 is a regular hexagon, the transverse cross section of the fixing block 10 is an isosceles triangle, and the number of fixing blocks 10 is set to six. When the first adjustment disk 7 rotates, the circumferentially distributed first adjustment grooves 8 drive the six fixing blocks 10 to slide along the regular hexagonal second adjustment groove 14 through the first slider 11. The sides of the isosceles triangle are always in contact with each other, so as to achieve stable clamping of specimen tubes of different diameters.

[0023] Specifically, there are six first adjustment slots 8, the included angle between adjacent first adjustment slots 8 is 60 degrees, and the fixing block 10 is made of medical silicone material.

[0024] As one embodiment of this utility model, the connecting sleeve 2, the first adjusting plate 7, the second adjusting plate 13, and the placement sleeve 3 are all coaxially arranged, and the coaxiality error of each component is controlled within a small range. When the connecting sleeve 2 rotates, the rotation centers of the first adjusting plate 7 and the second adjusting plate 13 are aligned, and the movement trajectory of the fixing block 10 is symmetrical about the axis, so that the specimen tube is always in the center position and aligned with the placement hole 15 and the through hole 9. Specifically, the axial deviation of each component is less than 0.3mm, and the assembly accuracy is ensured by mold positioning; the connection between the placement sleeve 3 and the fixing frame 1 is made of countersunk screws.

[0025] As an embodiment of this utility model, the side of the opening 4 has a first limiting ring groove 5, the side of the connecting sleeve 2 is equipped with a first limiting ring 6, the first limiting ring 6 rotates in the first limiting ring groove 5, the side of the second adjusting plate 13 has a second limiting ring groove 17, the inner wall of the connecting sleeve 2 is equipped with a second limiting ring 16 near its bottom surface, the second limiting ring 16 rotates in the second limiting ring groove 17. When the connecting sleeve 2 rotates, the first limiting ring 6 slides in the first limiting ring groove 5 to prevent the connecting sleeve 2 from moving up and down; the second limiting ring 16 slides in the second limiting ring groove 17 to limit the axial displacement of the connecting sleeve 2 and ensure that the distance between the first adjusting plate 7 and the second adjusting plate 13 is stable.

[0026] As an embodiment of this utility model, the first limiting ring 6 is a rubber ring. The elasticity of the rubber ring allows it to make close contact with the inner wall of the first limiting ring groove 5, generating appropriate static friction. When a certain external force is applied, the connecting sleeve 2 can be rotated. After the external force disappears, it maintains its current position, ensuring that the specimen tube is firmly clamped and will not loosen due to slight collisions.

[0027] Specifically, the first limiting ring 6 is set in the annular groove of the connecting sleeve 2 through an interference fit. After assembly, the static friction coefficient between the connecting sleeve 2 and the first limiting ring groove 5 is greater than 0.6, ensuring that the connecting sleeve 2 does not rotate on its own when there is no external force. As an embodiment of this utility model, further, the number of placement sleeves 3 and openings 4 are the same, and the number of placement sleeves 3 and openings 4 corresponds one-to-one. The openings 4 on the fixing frame 1 are distributed one-to-one with the placement sleeves 3. Each specimen tube is placed into a set of openings 4 and placement sleeves 3, and is clamped and fixed independently. The groups do not interfere with each other, improving the orderliness of batch testing.

[0028] Specifically, the placement sleeve 3 is cylindrical and made of transparent polyvinyl chloride, making it easy to observe whether the bottom of the specimen tube is placed in place.

[0029] As an embodiment of this utility model, a rubber pad is further installed on the bottom surface of the placement hole 15. After the specimen tube is placed into the placement hole 15, the bottom contacts the rubber pad. The elastic deformation of the rubber conforms to the bottom contour of the specimen tube, which not only absorbs the impact force during placement, but also restricts the lateral movement of the specimen tube through friction.

[0030] Specifically, all components are made of medical-grade materials and are resistant to high-temperature sterilization.

[0031] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
