Description

Technical Field

[0001] This utility model relates to the field of blood specimen preservation technology, and in particular to a blood specimen preservation box. Background Technology

[0002] Blood testing, a routine medical procedure, involves collecting blood samples from patients to conduct various physical examinations. For large-scale group testing, specialized blood sample storage boxes are often used for temporary storage to ensure stable preservation of the blood samples. The insertion port on the storage box is generally larger than the diameter of the blood collection tube. This larger port makes insertion easier and provides guidance, ensuring the tube is placed accurately and facilitating blood collection. If the port diameter is similar to the tube diameter, insertion may be difficult. However, during transport, the larger port can cause the blood collection tube to shake inside the storage box. Blood samples need to remain relatively stable during transport to ensure proper stratification of blood components. Shaking can disrupt this natural stratification, leading to incomplete separation of serum or plasma from blood cells, affecting subsequent serum or plasma component analysis. Shaking can also cause blood to splash onto the tube cap; if the cap is not sealed tightly, blood may leak out, contaminating the surrounding environment and increasing the risk of cross-infection. Furthermore, if the blood collection tube ruptures during shaking, blood leakage will result in sample loss, making testing impossible and requiring a repeat blood draw, causing additional pain and inconvenience to the patient. Based on the above technical problems, this invention provides a novel blood sample preservation box. Utility Model Content

[0003] The purpose of this invention is to provide a blood sample preservation box that can solve the above-mentioned technical problems.

[0004] This utility model provides a blood sample preservation box, including a box body. The box body has multiple evenly distributed insertion holes for placing blood collection tubes. Each insertion hole is a tapered hole, wider at the top and narrower at the bottom. A pair of sponge wheels are symmetrically arranged along the diameter of each insertion hole, with the distance between the sponge wheels slightly smaller than the outer diameter of the blood collection tube. This provides better clamping for the blood collection tubes, and the sponge wheels also have a cushioning and shock-absorbing function. Furthermore, the sponge is made of relatively hard sponge, and the sponge wheels consist of a hard wheel body surrounded by sponge.

[0005] Furthermore, the sponge wheel is rotatably connected to the inner wall of the insertion hole.

[0006] Furthermore, rotating rods are fixedly provided on both sides of the sponge wheel, and two slots are symmetrically provided on the inner wall of the insertion hole, with the rotating rods rotatably connected to the slots.

[0007] Furthermore, the inner wall of the insertion hole is provided with two opposing sliding grooves along the radial direction of the insertion hole. A sliding rod is slidably connected within the sliding groove, and the end of the sliding rod is rotatably connected to the sponge wheel. A spring is provided between the other end of the sliding rod and the end of the sliding groove. This design is for blood collection tubes with a diameter larger than commonly used sizes. When inserted into the insertion hole, it compresses the sliding rod and moves along the sliding groove, increasing the distance between the two sponge wheels, thus accommodating larger-sized blood collection tubes.

[0008] Furthermore, the blood collection tube includes a tube body and a tube bottom. The tube body has a slender cylindrical structure, and the tube bottom has a circular structure. The diameter of the insertion hole from top to bottom is larger than the diameter of the blood collection tube body.

[0009] Furthermore, the bottom of the insertion hole is provided with a receiving groove whose shape is adapted to the bottom shape of the blood collection tube. In this way, when the bottom of the blood collection tube is inserted into the receiving groove, the bottom of the blood collection tube is limited and the upper part is limited by the sponge wheel, which further enhances the stability of the blood collection tube.

[0010] Furthermore, the inner wall of the socket is provided with a photoelectric switch, which is a through-beam photoelectric switch, including a transmitter and a receiver, which are arranged opposite to each other. The output end of the photoelectric switch is connected to a timer, and a display screen for displaying the timer time is provided on one side of the top of the socket.

[0011] Furthermore, the top of the box is provided with a box cover, which is connected to the box body by a hinge.

[0012] Furthermore, it also includes a handle, the two ends of which are rotatably connected to the outer wall of the box. The handle allows the storage box to be carried by hand.

[0013] Furthermore, a counterweight is provided at the bottom of the box. The counterweight is cylindrical and threaded to the bottom of the box. A circular groove is provided at the bottom of the counterweight, and an arc-shaped handle is located within the groove. The two ends of the handle are hinged to the inner wall of the circular groove via damping shafts. Sometimes, when the storage box is transported using a trolley, the counterweight helps to keep the storage box stably upright.

[0014] Beneficial effects:

[0015] This novel blood specimen preservation box features a tapered insertion hole that is wider at the top and narrower at the bottom, retaining the advantage of traditional larger insertion holes for easier insertion of blood collection tubes. During blood collection, medical staff can easily align and insert the blood collection tube into the hole. The larger opening at the top provides significant guidance, reducing the difficulty of insertion and improving blood collection efficiency. Furthermore, compared to the traditional single large insertion hole design, the tapered bottom structure initially limits the placement of the blood collection tube from the bottom after insertion, making the tube more stable and preventing it from wobbling within the hole. When inserting the blood collection tube, the sponge wheel rubs against the outer wall of the tube, making insertion smoother. After insertion, the sponge wheel makes close contact with the outer wall of the tube, acting as a clamp and, together with the bottom of the tapered hole, providing a limiting effect to prevent the blood collection tube from wobbling within the hole. In the event of bumps or other disturbances, the sponge wheel can cushion the impact on the blood collection tube, preventing it from rupturing due to violent collisions caused by shaking.

[0028] Example 1

[0029] A blood specimen preservation box, such as Figure 1-3As shown, the device includes a housing 1, on which multiple insertion holes 2 for placing blood collection tubes are evenly distributed. Each insertion hole 2 is a tapered hole, wider at the top and narrower at the bottom. A pair of sponge wheels 3 are symmetrically arranged along the diameter of the inner wall of each insertion hole 2. The distance between the closest points of the sponge wheels 3 is slightly smaller than the outer diameter of the blood collection tube. This provides better clamping for the blood collection tubes, and the sponge wheels also have a cushioning and shock-absorbing function. Each sponge wheel consists of a rigid wheel body surrounded by a sponge, which can be made of a relatively hard sponge. The sponge wheels 3 are rotatably connected to the inner wall of the insertion holes 2. Specifically, rotating rods 4 are fixed on both sides of each sponge wheel 3, and two symmetrical slots 5 are provided on the inner wall of the insertion holes 2. The rotating rods 4 are rotatably connected to the slots 5.

[0030] The blood collection tube includes a tube body 901 and a tube bottom 902. The tube body 901 is a slender cylindrical structure, and the tube bottom 902 is a circular structure. The diameter of the insertion hole 2 from top to bottom is larger than the diameter of the blood collection tube body. The bottom of the insertion hole 2 is provided with a receiving groove 10, the shape of which is adapted to the shape of the tube bottom 902 of the blood collection tube. In this way, when the tube bottom of the blood collection tube is inserted into the receiving groove, the bottom of the blood collection tube is limited, and the upper part is limited by the sponge wheel, which better enhances the stability of the blood collection tube.

[0031] A photoelectric switch 11 is installed on the inner wall of socket 2. This photoelectric switch is a through-beam type, including a transmitter and a receiver, which are positioned opposite each other. A timer is connected to the output of the photoelectric switch. A display screen 19 for displaying the timer's duration is located on one side of the top of socket 2. There are time requirements for blood testing after blood collection, which vary depending on the test. Here are some common requirements: A complete blood count (CBC) is generally completed within 4 hours of blood collection. If the time is too long, the morphology and structure of cells in the blood may change, affecting the accuracy of the test results. For example, white blood cells may degrade, and platelets may aggregate. Tests for coagulation function-related indicators have stricter time requirements and should generally be completed within 1-2 hours of blood collection. This is because the activity of coagulation factors changes over time after blood leaves the body. Prolonged storage may prolong or shorten the coagulation time, affecting the accurate assessment of the patient's coagulation function. Therefore, a corresponding timing function needs to be designed to prevent the blood from being stored for too long from affecting the test results. To enable the photoelectric switch to perform the timing function, it usually needs to be used in conjunction with devices such as timers, counters, or microcontrollers, connecting the output of the photoelectric switch to the trigger input of the timer. Photoelectric switches generally have two output states: normally open and normally closed. The appropriate connection method should be selected based on actual needs. For example, if timing starts when the photoelectric switch detects an object, a normally open output is usually selected. When an object blocks the light, the normally open contact closes, triggering the timer. The relevant parameters of the timer should be set according to the required timing accuracy and duration. Timers typically have multiple timing modes, such as single-shot timing and cyclic timing. If measuring the time it takes for an object to pass through the photoelectric switch's detection area, a single-shot timing mode can be set, with the upper limit set according to the expected time range. When the photoelectric switch detects an object, its output state changes, triggering the timer to start timing. When the object leaves the detection range of the photoelectric switch, the photoelectric switch returns to its initial state. Timing can be stopped through appropriate circuit design (such as using the normally closed contact of the photoelectric switch to trigger the timer to stop when the object leaves) or the timer's own function (such as setting specific stop conditions). At this time, the time displayed on the screen is the time the object (blood collection tube) spent within the detection area (jack).

[0032] The top of the box 1 is provided with a box cover 12, which is connected to the box 1 via a hinge 13. It also includes a handle 14, the two ends of which are rotatably connected to the outer wall of the box 1. The handle 14 can be used to carry the storage box by hand.

[0033] Example 2

[0034] The basic structure is the same as in Example 1, such as... Figure 4-5As shown, the difference lies in the following: the inner wall of the insertion hole 2 has two opposing sliding grooves 6 along the radial direction of the insertion hole. A sliding rod 7 is slidably connected within the sliding groove 6. The end of the sliding rod 7 is rotatably connected to a sponge wheel, and a spring 8 is provided between the other end of the sliding rod 7 and the end of the sliding groove 6. This design is for blood collection tubes with a diameter larger than commonly used sizes. When inserted into the insertion hole 2, it compresses the sliding rod 7 and moves it along the sliding groove 6, increasing the distance between the two sponge wheels 3, thus accommodating larger-sized blood collection tubes. Although the bottom 902 of a larger-sized blood collection tube cannot be inserted into the receiving groove 10, the lower half of the insertion hole 2 can still provide a certain degree of restraint, such as... Figure 5 As shown.

[0035] Example 3

[0036] The basic structure is the same as in Example 1, such as... Figure 6-7 As shown, the difference lies in the following: The bottom of the box 1 is equipped with a counterweight 15. The counterweight 15 has a cylindrical structure and is threadedly connected to the bottom of the box 1. The bottom of the counterweight 15 has a circular groove 16, and an arc-shaped handle 17 is located within the circular groove 16. The two ends of the handle are hinged to the inner wall of the circular groove 16 via damping pivots 18. Sometimes, when the storage box is transported using a trolley, the counterweight 15 helps to keep the storage box stably upright. When the counterweight is not needed, the arc-shaped handle 17 is removed from the circular groove 16, and the counterweight 15 is rotated out of the circular groove 16 by holding the handle. When the counterweight is needed, the counterweight 15 is screwed back into the circular groove 16 by holding the handle, and the arc-shaped handle 17 is folded into the circular groove 16.

[0037] Furthermore, the sponge wheel used in this invention possesses excellent elasticity and flexibility, allowing it to adaptively adjust to the diameter, shape, and surface curvature of the blood collection tube, ensuring a tight fit. Whether the blood collection tube is of standard size or has slight dimensional variations, it can be stably clamped. The soft texture of the sponge wheel ensures surface contact with the blood collection tube, dispersing pressure and preventing localized pressure concentration. This effectively prevents the blood collection tube from being cracked or scratched, protecting its integrity and the safety of the blood sample within.

[0038] Compared to raised dots, sponge wheels offer a more consistent clamping force due to the relatively fixed shape and spacing of the raised dots. This can lead to inconsistent clamping force on non-standard sized or uneven blood collection tubes, resulting in unstable tube fixation. Furthermore, the raised dots create point contact with the blood collection tube. Under the same clamping force, the raised dots exert greater pressure on the tube surface, especially when the tube material is brittle or has weak points, making it more prone to breakage.

[0039] During blood collection or equipment movement, the sponge wheels provide excellent shock absorption and cushioning, reducing the impact of vibration on the blood collection tubes and preventing excessive blood sloshing, abnormal stratification, or hemolysis caused by vibration, thus helping to ensure the quality of the blood sample. Convex points, on the other hand, have relatively weak shock absorption capabilities and are less effective at buffering external vibrations, providing insufficient protection for the stability of the blood sample.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
