[0003] Although there are now fixing devices that can limit the tube body, most of the existing fixing devices are composed of a seat body, a suction cup, and a C-shaped slot (for example: Chinese patent application numbers CN202120947024.3, CN202223501869.3 and CN201721811168.6 and other patent documents disclosed). In this type of fixing device, the tube body is clamped by a C-shaped slot. Among them, the size of the C-shaped slot in the existing fixing device cannot be changed or the change range is relatively small, so this type of fixing device is only suitable for clamping tubes of a specific size. In order to clamp tubes of different sizes, it is necessary to configure a variety of fixing devices, which will result in a large investment cost.

[0004] Therefore, it is very necessary to design a tube positioning device used in a hemodialysis machine to solve the above technical problems. Utility Model Content

[0016] Preferably, a circle of moving convex ring is arranged on the outer edge of the suction cup.

[0017] The beneficial effects of the utility model are as follows: the tube body positioning device uses an adsorption seat body to facilitate rapid installation and positioning on the hemodialysis machine by adsorption.

And this can also help to stably restrict the tube body to reduce the shaking of the tube body, thereby reducing the adverse effects on the flow of related liquids, so as to ensure the quality of hemodialysis. The tube body positioning device can ensure that hemodialysis can be carried out more safely.

[0018] By embedding a detachable soft clamping block on the wall of the positioning notch, it is convenient to clamp tubes of different diameters by replacing soft clamping blocks of different sizes, so there is no need to configure different types of tube positioning devices, and only soft clamping blocks are needed.

[0031] like Figures 1 to 4As shown, the utility model describes a tube positioning device used in a hemodialysis machine, comprising an adsorption seat body 1, on which is opened at least one positioning notch 11, a detachable soft clamping block 2 is embedded on the mouth wall of the positioning notch 11, and a positioning hole 10 for clamping the tube body is reserved between the soft clamping block 2 and the mouth wall of the positioning notch 11.

[0032] In the tube positioning device, the adsorption seat 1 can be used to quickly install and position the tube on the hemodialysis machine by adsorption. A positioning hole 10 for clamping the tube is reserved between the soft clamping block 2 and the wall of the positioning notch 11, which can help to quickly and conveniently limit the tube on the hemodialysis machine, which can help to avoid the tube being too messy, so that it can be easy for doctors to identify and reduce scratches. And this can also help to stably limit the tube to reduce the shaking of the tube, thereby reducing the adverse effects on the flow of related liquids, so as to ensure the quality of hemodialysis. The tube positioning device can ensure that hemodialysis can be carried out more safely.

[0033] By embedding a detachable soft clamping block 2 on the wall of the positioning notch 11, it is convenient to clamp tubes of different diameters by replacing soft clamping blocks 2 of different sizes, so that there is no need to configure different types of tube positioning devices, and only the soft clamping block 2 is needed. Since the soft clamping block 2 is soft, it can help to play a very stable limiting role on the tube. In this way, the tube positioning device is conducive to stably clamping tubes of different sizes at a low cost, and the applicability and reliability of the tube positioning device are very good.

[0034] like Figures 1 to 4 As shown, a card slot 12 is provided on the mouth wall of the positioning notch 11, and the soft clamping block 2 can be detachably embedded in the card slot 12. The card slot 12 is used to position the soft clamping block 2, which can facilitate the convenient and stable positioning of the soft clamping block 2 on the mouth wall of the positioning notch 11, thereby ensuring that the installation and positioning of the soft clamping block 2 is very convenient and stable.

[0035] like Figures 1 to 5 As shown, the clamping slot 12 is a T-shaped clamping slot, and the embedding portion of the soft clamping block 2 matches the clamping slot 12. The T-shaped clamping slot can play a more stable and reliable positioning role for the soft clamping block 2, thereby helping to further improve the stability and reliability of the installation and positioning of the soft clamping block 2, and further helping to further improve the reliability of the tube body positioning device.

[0036] The soft clamping block 2 is formed of silicone or soft rubber, and the soft clamping block 2 is tightly embedded in the clamping groove 12, and the soft clamping block 2 can tightly clamp the tube body. In this way, the soft clamping block 2 can have very good soft properties, and the installation positioning and clamping effect of the soft clamping block 2 can be very stable.

[0037] like Figures 1 to 3 , Figure 5 As shown, the edge of the port of the clamping slot 12 is chamfered, and the end of the soft clamping block 2 is also chamfered, which can facilitate the embedding of the soft clamping block 2 and help improve the convenience of installing the soft clamping block 2.

[0038] like Figures 1 to 4 As shown, the positioning notch 11 is a C-shaped notch, the soft clamping block 2 is located on the wall of one side of the opening of the positioning notch 11, and the positioning hole 10 is formed between the soft clamping block 2 and the wall of the other side of the opening of the positioning notch 11. In this way, the wall of the positioning notch 11 can play a good limiting role on the tube body, so that the positioning hole 10 can have a more stable clamping effect, which helps to further improve the reliability and applicability of the tube body positioning device.

[0039] like Figures 1 to 5 As shown, the soft clamp block 2 is provided with an arc-shaped slot 21, and the slot opening of the arc-shaped slot 21 faces the wall of the positioning notch 11, and the positioning hole 10 is formed by the slot wall of the arc-shaped slot 21 and the wall of the positioning notch 11. The slot wall of the arc-shaped slot 21 and the wall of the positioning notch 11 together enclose the positioning hole 10, which can help to play a stable and reliable clamping role on the tube body, which can further improve the reliability and applicability of the tube body positioning device.

[0040] like Figures 1 to 5 As shown, the wall of the positioning notch 11 is also arc-shaped, and the axial centerline of the positioning notch 11 is coaxial or parallel to the axial centerline of the arc-shaped clamping groove 21. In this way, the clamping effect of the positioning hole 10 on the pipe body can be more stable and reliable, thereby achieving a more stable and reliable positioning effect on the pipe body.

[0041] like Figures 1 to 4 As shown, the soft clamp block 2 is provided with a covering surface 22 matching the wall of the positioning notch 11, and the covering surface 22 is attached to the wall of the positioning notch 11. In this way, the installation and positioning of the soft clamp block 2 can be more stable and reliable, so that the soft clamp block 2 can play a more stable and reliable clamping role.

[0042] like Figure 2 and Figure 3 As shown, the adsorption seat body 1 includes a card seat 13 and at least one suction cup 14, the positioning notch 11 is opened on the card seat 13, and the suction cup 14 is arranged on the outer wall of the card seat 13. Such an adsorption seat body 1 is very simple and reliable, which is not only convenient for manufacturing, but also ensures that the tube body positioning device has a very good positioning effect on the tube body.

[0043] like Figure 1As shown, a writing plane and / or a pasting plane 131 are provided on the outer wall of the holder 13. The writing plane can be used to write identification information, and the pasting plane 131 can be pasted with a patch with identification information, so that it is convenient to identify which tube body is clamped by the tube body positioning device through the identification information, which can help reduce the convenience of identification for medical workers.

[0044] like Figure 3 , Fig. 9 and Fig.10 As shown, the two ends of the holder 13 are respectively provided with T-shaped slots 132. When it is necessary to accurately define two or more tube body positioning devices 100 together, a connecting block 20 will be used, and the two ends of the connecting block 20 are respectively provided with T-shaped embedding heads 201 matching the T-shaped slots 132. Each tube body positioning device 100 is arranged side by side, and a connecting block 20 is arranged between adjacent tube body positioning devices 100, and the T-shaped embedding heads 201 at both ends of the connecting block 20 are respectively embedded in the T-shaped slots 132 of two adjacent tube body positioning devices 100. In this way, it is conducive to accurately and stably arranging more than two tube body positioning devices 100 together, so that it is conducive to accurately and stably arranging related tubes together, which helps to further improve the accuracy of tube body positioning, which is more convenient for medical workers to identify.

[0045] like Fig.11 and Fig.12 As shown, when more than two positioning notches 11 are provided on a holder 13 , it is not necessary to provide a T-shaped slot 132 on the holder 13 , so that a plurality of tubes can be accurately defined together.

[0046] like Figures 2 to 4 As shown, the base 13 is provided with a positioning groove 133, the rear end of the suction cup 14 is embedded in the positioning groove 133, a clamp ring 15 is arranged at the bottom of the suction groove 141 of the suction cup 14, a locking screw 16 is arranged in the suction groove 141, and the threaded end of the locking screw 16 passes through the inner hole of the clamp ring 15 and the suction cup 14 in sequence, and then is screwed to the base 13. In this way, the suction cup 14 can be accurately and stably limited on the base 13, thereby helping to improve the accuracy and stability of the installation and positioning of the suction cup 14.

[0047] like Figure 4 As shown, the clamp ring 15 is a stainless steel washer, the rear end of the suction cup 14 is a column 142, the column 142 is embedded in the positioning groove 133, and the threaded end of the locking screw 16 passes through the inner hole of the clamp ring 15 and the column 142 in sequence and then is screwed to the bottom of the positioning groove 133. In this way, the suction cup 14 can be more stably limited, thereby further improving the stability and reliability of the installation and positioning of the suction cup 14.

[0048] like Figure 4As shown, a circle of toggle convex ring 143 is arranged on the outer edge of the suction cup 14. The toggle convex ring 143 can be acted upon by a finger, so that when the finger pushes the toggle convex ring 143 to roll toward the center of the suction cup 14, the outer edge of the suction cup 14 can be driven to tilt upward by the toggle convex ring 143, so that the suction cup 14 can quickly lose its adsorption effect, which helps to improve the convenience of peeling off the suction cup 14, and further helps to further improve the convenience of using the tube body positioning device.

[0049] like Figures 1 to 4 As shown, the upper end of the card holder 13 is C-shaped and the lower end is rectangular, the inner wall of the upper end of the C-shape encloses a positioning notch 11, the card slot 12 is opened on the lower wall of the positioning notch 11, the top surface of the soft clamping block 2 and the upper wall of the positioning notch 11 together enclose a positioning hole 10, two T-shaped card slots 132 are respectively opened on the left and right side walls of the lower end of the card holder 13, the positioning slot 133 is opened on the bottom surface of the card holder 13, and the writing plane and / or pasting plane 131 are located on the top surface of the card holder 13. This not only makes the card holder 13 have a very simple structure, but also ensures that the card holder 13 has a very high reliability and can be convenient to use.

[0050] like Figures 6 to 8 As shown, in actual use, except for the soft clamping block 2, other components on the tube body positioning device can be universal, so that by configuring soft clamping blocks 2 of different sizes, and then according to the diameter of the tube body 30, the soft clamping block 2 of the appropriate size can be selected to clamp the tube body 30. In this way, the tube body positioning device is conducive to stably clamping tubes of different sizes at a low cost.

[0051] When the tube body 30 needs to be positioned, the soft clamp block 2 is not installed first; then the opening of the suction cup 14 is directed toward the hemodialysis machine and the card seat 13 is pressed hard to discharge the air in the suction cup 14, so that the tube body 30 can be adsorbed on the hemodialysis machine through the suction cup 14; then the tube body 30 is placed in the positioning notch 11; then a soft clamp block 2 of appropriate size is selected, and the soft clamp block 2 is embedded in the positioning notch 11, and the soft clamp block 2 is embedded in the card-mounting groove 12, and the soft clamp block 2 and the wall of the positioning notch 11 are used to clamp the tube body 30; this way, the positioning of the tube body 30 can be completed. When the tube body 30 needs to be disassembled, the soft clamp block 2 is first moved to disengage it from the positioning notch 11; then the tube body 30 can be disengaged from the positioning notch 11; finally, the protruding ring 143 is pushed and moved with a finger to make the suction cup 14 lose its adsorption effect; this way, the disassembly can be completed.
