Description

Technical Field

[0001] This application relates to the field of blood analysis technology, and in particular to an easy-to-install tubing for blood analysis. Background Technology

[0002] Fully automated blood analyzers are now widely used in hospitals at all levels, medical testing laboratories, and regional testing centers due to their fast measurement speed, high accuracy, and low reagent consumption.

[0003] However, currently, the gas tubes connecting the various gas components inside the analytical instrument are all connected by quick-connect couplings. However, this quick-connect coupling connection to the gas tube cannot completely prevent gaps from forming between the quick-connect coupling and the gas tube during instrument operation or due to some vibrations, which can lead to poor sealing or even the gas tube and quick-connect coupling falling off. Utility Model Content

[0004] To improve the problem of poor sealing and detachment between quick-connect couplings and trachea caused by vibration and other factors, this application provides an easy-to-install tubing for blood analysis.

[0005] The present application provides a convenient-to-install tubing for blood analysis, which adopts the following technical solution:

[0006] A blood analysis tubing that is easy to install includes an analyzer pressure regulating valve. A quick connector is fixedly provided at the lower part of the analyzer pressure regulating valve. An air tube is snapped and fixed in the inner cavity of the quick connector. A tube head is fixedly provided on the outer ring surface of one end of the air tube in the inner cavity of the quick connector. An elastic sealing ring is provided on the side of the tube head away from the quick connector. Several lifting mechanisms with the same structure and installation method are arranged in an array on the inner ring surface of the elastic sealing ring.

[0007] The lifting mechanism includes a top plate fixed on the inner ring surface of the elastic sealing ring. The top plate has four vertical sliding rods with the same structure fixed at its four corners on the side away from the elastic sealing ring. The four vertical sliding rods are connected to the same diagonal connecting rods on the side away from the top plate. The four diagonal connecting rods are connected to two horizontal rods with the same structure on the side away from the vertical sliding rods. The two horizontal rods are fixed with a push-pull rod in the middle.

[0008] A fixed ring is fixed on the side of the push-pull rod away from the crossbar. A lower sleeve is fixed on the side of the fixed ring away from the lifting mechanism. An outer sleeve is threadedly connected to the side of the lower sleeve away from the fixed ring. A lower sliding ring, which is fixed to the air pipe, is rotatably provided on the side of the outer sleeve away from the lower sleeve.

[0009] By adopting the above technical solution, the air tube and quick connector are connected at one end with a tube head and an elastic sealing ring, which can further achieve a sealing effect on the air tube and quick connector. Furthermore, with the cooperation of the lifting mechanism and the elastic sealing ring, as well as the assistance of the fixing ring, the lower ring sleeve and the outer ring sleeve, the air tube and quick connector can achieve a better fastening effect.

[0010] Preferably, the lifting mechanism further includes an outer frame fixed to the outer ring surface of the trachea, and the bottom of the inner cavity of the outer frame is provided with four mutually symmetrical and structurally consistent spiral grooves.

[0011] By adopting the above technical solution, the loop slide can make the two ends of the crossbar move inside it, enter from the bottom of the loop slide and exit from the top of the loop slide, thereby realizing a moving loop.

[0012] Preferably, the bottom of the spiral groove is fixed with several limiting blocks of the same structure that abut against the crossbar.

[0013] By adopting the above technical solution, the limiting block can abut against the crossbar to limit movement when the crossbar loses its thrust.

[0014] Preferably, each of the four vertical slide bars has a vertical slide groove that is fixedly disposed on both sides of the frame.

[0015] By adopting the above technical solution, the vertical slide groove can guide and limit the vertical slide rod and the diagonal connecting rod.

[0016] Preferably, a fixing block is fixedly provided through the middle of the crossbar and is fixedly connected to the end of the push-pull rod away from the fixing ring.

[0017] By adopting the above technical solution, the fixing block can fix the crossbar and the push-pull rod together, making them a single unit.

[0018] Preferably, the inner cavity of the spiral groove away from the fixing ring is provided with a baffle fixedly installed with the outer frame.

[0019] By adopting the above technical solution, the baffle can divide the spiral groove into upper and lower channels, thereby guiding the crossbar and enabling the crossbar to move smoothly within the spiral groove.

[0020] Preferably, the lower part of the lower collar is fixedly provided with an external thread that slides and connects with the air pipe.

[0021] By adopting the above technical solution, the external thread can help connect the lower ring sleeve and the outer sleeve.

[0022] Preferably, the inner annular surface of the outer sleeve is provided with an internal thread that is threaded to the external thread.

[0023] By adopting the above technical solution, the internal thread inside the outer sleeve can connect with the lower collar while also pushing or pulling the lower collar back.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By using the cooperation of the outer sleeve and the lower collar, the fixing ring can push the push-pull rod, which in turn drives the horizontal bar and the diagonal connecting rod to move, thereby pushing the vertical slide bar outward, causing the top plate and the elastic sealing ring to open outward and abut against the inner wall of the quick connector, thus further fixing the air tube and the quick connector and preventing loosening during vibration.

[0026] 2. By utilizing the interaction between the pipe head and the elastic sealing ring, and under the action of the lifting mechanism, the elastic sealing ring is pushed outward and abuts against the quick connector. When the elastic sealing ring is stretched outward, there will be no gap between its inner diameter and the outer diameter of the pipe head, thus achieving a better sealing effect.

[0036] The following is combined with Figures 1-6This application will be described in further detail.

[0037] This application discloses an easy-to-install tubing for blood analysis.

[0038] Reference Figure 1 , Figure 2 , Figure 4 A blood analysis tubing for easy installation includes an analyzer pressure regulating valve 1 located inside the blood analyzer and a quick connector 2 fixedly disposed below the analyzer pressure regulating valve 1. The quick connector 2 is snapped into one end of a trachea 3 within its inner cavity. A tube head 4 is fixedly disposed on the outer ring surface of the end of the trachea 3 that is snapped into the inner cavity of the quick connector 2. The tube head 4 is slidably disposed with an elastic sealing ring 5 on the side away from the quick connector 2.

[0039] It should be noted that the analyzer pressure regulating valve 1 and quick connector 2 are existing technologies, and their structural principles will not be elaborated on here.

[0040] The tube head 4, which is fixed at one end of the tube 3 and the quick connector 2, can play a certain role in sealing and stabilizing the structure below the tube head 4. Furthermore, the tube head 4 can provide a certain resistance to the elastic sealing ring 5 when it is in operation. When the elastic sealing ring 5 is stretched outward, its inner diameter will not exceed the outer diameter of the tube head 4, thus preventing the sealing effect from failing.

[0041] Reference Figure 5 , Figure 6 The inner ring surface of the elastic sealing ring 5 is provided with several lifting mechanisms 6 arranged in an array, and the structure and installation method of the lifting mechanisms 6 are the same. The lifting mechanism 6 includes a top plate 61 fixedly installed on the inner ring surface of the elastic sealing ring 5, and four vertical slide rods 62 are fixedly installed at the four corners of the surface of the top plate 61 away from the elastic sealing ring 5. The four vertical slide rods 62 have the same structure and are symmetrical to each other. Vertical slide grooves 68 are slidably installed on both sides of the four vertical slide rods 62, and one side surface of the four vertical slide grooves 68 is fixedly installed with the side surface of the inner cavity of the outer frame 611.

[0042] Reference Figure 5 , Figure 6 The four vertical sliding rods 62 are rotatably connected to one end of the four diagonal connecting rods 63 on the side away from the top plate 61. The four diagonal connecting rods 63 have the same structure and are symmetrical to each other. The four diagonal connecting rods 63 are movably connected to the two ends of the two horizontal rods 64 on the side away from the vertical sliding rods 62 and are rotatably connected to each other. The two horizontal rods 64 have the same structure and are fixedly connected to the middle of both sides of the fixing block 69 in the middle of the two horizontal rods 64. The middle of the adjacent sides of the two fixing blocks 69 are fixedly connected to the surface of the push-pull rod 65 on the side away from the fixing ring 7. However, it should be noted that the two ends of the push-pull rod 65 located at the front are fixedly connected to the two sides of the fixing block 69 respectively, so as to connect the front and rear ends and make them into a whole.

[0043] Reference Figure 5 , Figure 6 The lifting mechanism 6 also includes an outer frame 611 fixedly mounted on the outer ring surface of the air pipe 3. Four spiral grooves 67 are arrayed at the bottom of the inner cavity of the outer frame 611. The four spiral grooves 67 are symmetrical and structurally identical. A baffle 610 is provided in the middle of the inner cavity of the spiral groove 67 on the side away from the fixed ring 7. One side surface of the baffle 610 is fixedly mounted to the side wall of the inner cavity of the outer frame 611. The baffle 610 is located in the middle of the spiral groove 67, dividing it into upper and lower channels. The diameters of all the components are larger than the diameter of the crossbar 64. Several limiting blocks 66 are fixedly installed on the bottom channel of the loop 67. The limiting blocks 66 have the same structure and the vertical side of the limiting blocks 66 is set as an arc-shaped groove that can hold the crossbar 64 in place, thereby achieving the abutment and limiting of the crossbar 64. The distance between the highest point of the limiting block 66 and the highest point of the lower channel formed by the loop 67 and the baffle 610 is 2-4 mm greater than the diameter of the crossbar 64, so that the crossbar 64 can move freely in the loop 67.

[0044] Pushing the push-pull rod 65 moves the fixed block 69 and the crossbar 64 together, which in turn causes the crossbar 64 to move the lower end of the diagonal connecting rod 63 within the loop groove 67. After moving a certain distance within the loop groove 67, the crossbar 64 abuts against the limiting block 66 to prevent backward movement. When the crossbar 64 moves the lower end of the diagonal connecting rod 63, it will push the upper end of the diagonal connecting rod 63, along with the vertical sliding rod 62, to move longitudinally in the vertical groove 68. When the vertical sliding rod 62 moves, it can move the top plate 61 together, thereby causing the top plate 61 to push the elastic sealing ring 5 fixed to it outward, so as to abut against the inner wall of the quick connector 2 to achieve a further fixing and sealing effect, which can prevent the air tube 3 from falling off due to reverse pulling or vibration.

[0045] Reference Figure 3 , Figure 4 , Figure 5 The surface of the push-pull rod 65 away from the crossbar 64 is fixedly connected to the annular surface of the fixed ring 7. The surface of the fixed ring 7 away from the push-pull rod 65 in the lifting mechanism 6 is fixedly connected to the surface of the lower sleeve ring 8. An external thread 10 is fixedly provided on the lower outer ring surface of the lower sleeve ring 8. The inner ring surface of the external thread 10 is slidably connected to the outer ring surface of the air tube 3. The external thread 10 provided at the lower part of the lower sleeve ring 8 is connected to an internal thread 11. The internal thread 11 is provided on the inner ring surface of the outer sleeve tube 9, so that the outer sleeve tube 9 and the lower sleeve ring 8 can be threadedly connected. When the outer sleeve tube 9 rotates, it can drive the lower sleeve ring 8 to move linearly. The side of the outer sleeve tube 9 away from the lower sleeve ring 8 is rotatably set with the lower sliding ring 12. The inner ring surface of the lower sliding ring 12 is fixedly connected to the outer ring surface of the air tube 3.

[0046] It should be noted that, starting from the position where the tube head 4 abuts against the elastic sealing ring 5, the outer ring diameter of the air tube 3 is reduced by half. This leaves space for the elastic sealing ring 5, lifting mechanism 6, fixing ring 7, lower sleeve ring 8, and outer sleeve 9 to be fitted onto the outside of the air tube 3, so that the outer ring surfaces of the elastic sealing ring 5, lifting mechanism 6, fixing ring 7, lower sleeve ring 8, and outer sleeve 9 can be on the same plane as the outer ring surface of the air tube 3 exposed outside the quick connector 2.

[0047] The fixed ring 7 serves as the transmission hub between the push-pull rod 65 and the lower sleeve ring 8, enabling better transmission of the thrust output by the lower sleeve ring 8 to the push-pull rod 65, thereby pushing or pulling the push-pull rod 65. The lower sleeve ring 8 acts as the carrier of the external thread 10, providing stability to the external thread 10. When the external thread 10 is threadedly connected to the internal thread 11 inside the outer sleeve tube 9, turning the outer sleeve tube 9 allows the internal thread 11 to push or pull the external thread 10 out using the thread. When the outer sleeve tube 9 rotates, the sliding ring 12, which is connected to it, is fixedly connected to the air pipe 3, providing support for the rotation of the outer sleeve tube 9. This allows the outer sleeve tube 9 and the internal thread 11 to rotate, while the lower sleeve ring 8 and the external thread 10 do not rotate with it. This allows the outer sleeve tube 9 to drive the lower sleeve ring 8 to move back and forth, thereby moving the fixed ring 7, which is fixedly connected to the lower sleeve ring 8, and the push-pull rod 65, which is fixedly connected to the fixed ring 7, together.

[0048] The implementation principle of an easy-to-install tubing for blood analysis according to an embodiment of this application is as follows: First, insert the trachea 3 into the pressure regulating valve 1 of the analyzer, and then turn the outer sleeve 9. When the internal thread 11 inside the outer sleeve 9 rotates, it pushes the external thread 10 and the lower collar 8 forward. When the lower collar 8 moves forward, it can drive the fixed ring 7 and the push-pull rod 65 to move forward together. Then, the push-pull rod 65 drives the horizontal bar 64 to move forward, and drives the lower end of the inclined connecting rod 63 to move in the loop groove 67. When the horizontal bar 64 pushes the lower end of the inclined connecting rod 63, the upper end of the inclined connecting rod 63 simultaneously drives the vertical sliding rod 62 to move outward in the vertical sliding groove 68. When the vertical sliding rod 62 moves outward, it will drive the top plate 61 and the elastic sealing ring 5 to move outward together. Then, the elastic sealing ring 5 is pushed outward against the surface of the tube head 4 and abuts against the inner wall of the quick connector 2. Furthermore, the interaction between the elastic sealing ring 5 and the tube head 4 can also achieve a sealing effect.

[0049] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
