Technical Field

[0001] The utility model relates to the technical field of serum separation, in particular to a serum separator which is convenient for separation. Background Technique

[0002] Serum refers to the pale yellow transparent liquid separated from plasma after removing fibrinogen and certain coagulation factors after blood coagulation, or plasma from which fibrinogen has been removed. During biological experiments, blood is usually centrifuged first. After centrifugation, the serum will float on the liquid surface, and then the serum is separated from the blood through a separator to achieve serum separation.

Therefore, a serum separator which is convenient for separation is proposed. Content of the Utility Model

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0029] Please refer to Figure 1-7, A serum separator that is easy to separate, including a box cover 1 and a box bottom 6. The box cover 1 and the box bottom 6 are integrally formed and can be combined into a sampling box through a snap structure. Limiting frames 3 are provided on the inner walls of both the box cover 1 and the box bottom 6. The limiting frames 3 are annular and integrally formed with the box cover 1 and the box bottom 6. An outer rubber ring 4 is placed inside the limiting frame 3 of the box bottom 6. Among them, the outer rubber ring 4 is transparent and has a sampling hole 5 opened in the middle. Through the transparent outer rubber ring 4, the separation of serum can be observed. Through the sampling hole 5, blood samples can be added. Inside the outer rubber ring 4, a serum separation filter paper 9, an isolation film 10, an isolation paper 11, and a drying sheet 12 are sequentially stacked. Among them, the serum separation filter paper is spiral-shaped. Red blood cells precipitate, and serum separates outward along the spiral shape. When the separation is completed, the yellow part outside the blood is the filtered serum. Among them, the isolation film plays a role in supporting and isolating the lower layer to prevent the blood from seeping downward excessively and overflowing. The isolation paper and the isolation film together play a role in preventing the blood from seeping excessively. The drying sheet plays a role in drying blood spots and absorbing excessive blood, so as to prevent the situation of excessive blood seepage. A limiting component is vertically installed on the box cover 1. The limiting component sequentially passes through the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 for fixation, so as to effectively prevent the serum separation filter paper 9, the isolation film 10, the isolation paper 11, the drying sheet 12, and the outer rubber ring 4 from moving.

[0030] In this embodiment, the inner diameter of the limiting frame 3 is slightly larger than the inner diameter of the outer rubber ring 4, so that the outer rubber ring 4 can be limited inside the limiting frame 3, avoiding the situation that the outer rubber ring 4 moves inside the sampling box when the sampling box is closed, resulting in blood overflow.

[0031] In this embodiment, limiting holes 7 are opened on the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12. The limiting component is respectively clamped with the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 through the limiting holes 7. Among them, the limiting component includes a support rod 2 vertically installed on the box cover 1 and a limiting rod 8 sleeved on the top of the support rod 2. The limiting rod 8 is respectively clamped with the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 through the limiting holes 7. In this way, the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 can be fixed inside the outer rubber ring 4 and cannot move, so as to achieve the fixation effect and further achieve the effect of improving the filtration efficiency.

[0032] In this embodiment, an installation groove 15 is formed at the bottom of the limit rod 8, a spring 14 is installed inside the installation groove 15, and a limit plate 13 is installed at one end of the spring 14 away from the inner wall of the installation groove 15. The top of the support rod 2 is fixedly connected to the bottom of the limit plate 13. Through the elastic force of the contraction of the spring 14, when the box cover 1 is covered on the box bottom 6, it can prevent the length of the limit rod 8 from being too long and getting stuck with the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12, so that the limit rod 8 cannot pass through the bottom layer of the serum separation filter paper 9, resulting in the inability to fix the serum separation filter paper 9. At the same time, when the sampling box is closed with greater force, the situation where the limit rod 8 pierces through the box bottom 6 may occur, thus achieving the effect of protecting the sampling box.

[0033] Working principle: Place the outer rubber ring 4 inside the limit frame 3 of the box bottom 6, and then place the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 in sequence inside the outer rubber ring. Then adjust their positions so that the limit holes 7 on the serum separation filter paper 9, the isolation film 10, the isolation paper 11, and the drying sheet 12 are connected. Then cover the box cover 1 so that the limit rod 8 passes through several limit holes 7 and is connected to the bottom of the outer rubber ring 4, fixing the outer rubber ring 4 between the limit rod 8 and the box bottom 6, thereby achieving the effect of fixing the serum separation filter paper 9, the isolation film 10, the isolation paper 11, the drying sheet 12, and the outer rubber ring 4.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
