[0040] Embodiment 1

[0041] The present embodiment relates to a blood transfusion tube fixing device for a plasma separator, which is used to store and organize the blood transfusion tube 5 of the plasma separator to reduce the bending of the blood transfusion tube 5 .

[0042] In terms of overall structure, the device for fixing the blood transfusion tube 5 of the plasma separator comprises a storage body 1 and a shell 2, and a portion of the blood transfusion tube 5 is wound around the storage body 1. The shell 2 is detachably connected to the storage body 1 and is arranged outside the portion of the blood transfusion tube 5 wound around the storage body 1. The shell 2 is provided with at least one socket 201, and the two ends of the blood transfusion tube 5 pass through or pass through the shell 2 through the socket 201.

[0043] The plasma separator blood transfusion tube 5 fixing device of the utility model can wind a longer blood transfusion tube 5 on the storage body 1, and then cover the outer side with the shell 2, so that the excess blood transfusion tube 5 can be wound, rolled and fixed, and the blood transfusion tube 5 is not easy to bend.

[0044] Based on the above overall introduction, the fixing device of the plasma separator blood transfusion tube 5 in this embodiment is as follows Figures 1 to 4 As shown, the housing 2 is connected to the storage body 1, and the housing 2 is provided with a socket 201 for the blood transfusion tube 5 to pass through. In specific implementation, the excess blood transfusion tube 5 is wrapped around the storage body 1, and after the housing 2 is installed, the two ends of the blood transfusion tube 5 pass through the socket 201. Due to the combined effect of the storage body 1 and the housing 2, the blood transfusion tube 5 can be restricted in the housing 2, so that the blood transfusion tube 5 is not easy to bend. In this embodiment, two sockets 201 are preferably provided for the two ends of the blood transfusion tube 5 to pass through respectively.

[0045] It should be noted that it is also possible to set up one socket 201, as long as both ends of the blood transfusion tube 5 pass through the same socket 201, which does not affect the actual use function of the shell 2. Alternatively, multiple sockets 201 are set up, and after the shell 2 is connected to the storage body 1, an appropriate socket 201 can be selected at will for the blood transfusion tube 5 to pass through, which is more convenient for the operator to use.

[0046] As a preferred embodiment, the storage body 1 includes a mounting portion 101 and a winding portion 102, the mounting portion 101 is connected to a mounting base 3, and the blood transfusion tube 5 is wound around the winding portion 102. The mounting portion 101 is a rectangular plate, and the winding portion 102 is a cylinder. The winding portion 102 and the mounting portion 101 are integrally formed, and the winding portion 102 is perpendicular to the mounting portion 101, so that the blood transfusion tube 5 can be easily wound around the winding portion 102. The mounting base 3 can be the shell of a plasma separator, a test table, or other adhered objects.

[0047] Specifically, the housing 2 is plugged into the mounting portion 101 or the winding portion 102. The plugging method can make the installation of the housing 2 more convenient and easier to disassemble. Corresponding to the shape of the winding portion 102, the housing 2 is set to be a cylindrical shape with one end open. A socket 201 is provided on the circumferential side wall of the open end of the housing 2, and the socket 201 is passed through in the direction of the opening of the housing 2. In specific implementation, the blood transfusion tube 5 is firstly wound on the winding portion 102, and then the positions of the two ends of the blood transfusion tube 5 are adjusted to correspond to the socket 201 of the housing 2. The housing 2 is opened toward the winding portion 102 and the receiving body 1 is inserted, so that the blood transfusion tube 5 can be confined in the socket 201 and the position of the blood transfusion tube 5 can be locked.

[0048] For example, when the housing 2 is selected to be plugged into the winding portion 102, refer to Figure 1 The end of the housing 2 away from the opening is provided with a plug hole 202, the diameter of which is slightly smaller than the winding portion 102. After the winding portion 102 is inserted into the plug hole 202, the winding portion 102 and the plug hole 202 are interference-fitted, and the installation of the housing 2 is completed. When selecting the housing 2 to be plugged into the installation portion 101, refer to Figure 2 A boss 104 is provided at the connection between the mounting portion 101 and the winding portion 102. The diameter of the boss 104 is slightly larger than the inner diameter of the opening of the shell 2. The shell 2 is put on the boss 104, and the boss 104 and the opening of the shell 2 are interference fit, and the installation of the shell 2 is completed.

[0049] As a preferred embodiment, refer to Figure 3 and Figure 4 The mounting portion 101 is provided with an adhesive member 103 for bonding with the mounting base 3. The adhesive member 103 can quickly bond the mounting portion 101 with the mounting base 3, has fewer restrictions on use, and has more choices for mounting locations, such as the housing of a plasma separator, a test table, or other surfaces that can be adhered to. Further preferably, the adhesive member 103 is a suction cup or adhesive.

[0050] When the suction cup is selected as the adhesive member 103, the suction cup is pressed and adsorbed on a smooth plane or curved surface, so that the installation of the mounting portion 101 can be completed quickly. When removing or adjusting the position, it is only necessary to tilt the suction cup, which is more convenient for the operator to operate. In this embodiment, four suction cups are provided, which are respectively located at the four corners of the mounting portion 101 on the side facing away from the winding portion 102, so that the installation of the mounting portion 101 can be more firmly and reliably installed.

[0051] When selecting adhesive as the adhesive member 103, refer to Figure 4 The adhesive can be made into a long strip and pasted on the side of the mounting portion 101 away from the winding portion 102. Two strips of adhesive are provided, which are located at the upper part and the lower part respectively. The two strips of adhesive are arranged in parallel, which can obtain a better bonding effect. The adhesive strip can be used as an adhesive to adhere to the surface of various objects, and has a wider range of applications.

[0052] As a preferred embodiment, refer to Figure 1 and Figure 5 The mounting portion 101 is provided with a tube clamp 4, which is used to clamp the blood transfusion tube 5. The tube clamp 4 is a C-shaped elastic clamp, and the blood transfusion tube 5 can be fixed by clamping the blood transfusion tube 5 into the tube clamp 4, so that the blood transfusion tube 5 is not easy to shake when in use. Specifically, two tube clamps 4 can be provided to fix the two ends of the blood transfusion tube 5, so that the blood transfusion tube 5 wound around the winding portion 102 is not easy to move.

[0053] In order to reduce the bending effect of the tube clamp 4 on the blood transfusion tube 5, the tube clamp 4 is rotatably connected to the mounting portion 101. The blood transfusion tube 5 will show a certain natural curvature due to its own elasticity. This natural curvature does not affect the flow of the liquid in the blood transfusion tube 5. If the position of the tube clamp 4 is not good, the blood transfusion tube 5 may be slightly bent and deformed. The tube clamp 4 is rotatably connected to the mounting portion 101, and the rotation axis is perpendicular to the mounting portion 101. After the blood transfusion tube 5 is clamped into the tube clamp 4, the tube clamp 4 rotates under the elastic effect of the blood transfusion tube 5, and the blood transfusion tube 5 can be kept in a natural bending state, which is conducive to the flow of the liquid in the tube.

[0054] Embodiment 2

[0055] This embodiment relates to a device for fixing a blood transfusion tube 5 of a plasma separator. Figure 6 and Figure 7 As shown, the difference from the first embodiment is that the mounting portion 101 is not provided with an adhesive member 103. In this embodiment, the mounting portion 101 is provided with an insert block 1011, and the insert block 1011 is inserted into the mounting base 3. It should be noted that a hole position needs to be preset on the mounting base 3, and the insert block 1011 is inserted into the hole position, and the mounting portion 101 abuts against the mounting base 3 to complete the insertion of the storage component.

[0056] As a preferred example, the plug block 1011 is a cylinder, and a locking tongue 1012 is radially slidably penetrated through the circumferential side wall of the plug block 1011, and a locking groove 301 matching the shape of the locking tongue 1012 is provided in the mounting base 3. After the plug block 1011 is inserted into the mounting base 3, the locking tongue 1012 is inserted into the locking groove 301, and the position of the plug block 1011 in the mounting base 3 can be locked.

[0057] Specifically, a compression spring 1013 is provided between the lock tongue 1012 and the plug block 1011, and the end of the lock tongue 1012 away from the compression spring 1013 is a semi-circular table, and the large end of the semi-circular table faces the mounting portion 101. The two ends of the compression spring 1013 are respectively fixedly connected to the lock tongue 1012 and the plug block 1011, and the lock tongue 1012 can be pushed away from the central axis of the plug block 1011 in a compressed state. In this embodiment, a lock tongue 1012 is provided on each side of the plug block 1011. The end of the plug block 1011 is also chamfered to facilitate the insertion of the plug block 1011 into the mounting base 3.

[0058] During the implementation, when installing the storage member, the insert block 1011 is gradually inserted into the installation base 3, and the side wall of the installation base 3 will block the push of the lock tongue 1012, so that the lock tongue 1012 is received in the insert block 1011, until the lock tongue 1012 is directly opposite to the lock groove 301, the lock tongue 1012 pops out to play a backstopping role, and the insert block 1011 is locked. When disassembling the storage member, the storage member is rotated around the central axis of the insert block 1011, and the groove wall of the lock groove 301 will squeeze and push the lock tongue 1012, so that the lock tongue 1012 is pressed into the insert block 1011, and the insert block 1011 can be pulled out.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
