[0029] The elastic tension member between the push block and the guide seat.

[0030] In the above technical solution, the thoracic surgery nursing anti-blockage drainage monitoring system provided by the present invention has the following beneficial effects: Drainage fluid first enters the receiving chamber, and then is guided into the constant flow chamber by a fixedly connected metering valve. If the accumulated fluid increases, the fluid in the receiving chamber cannot be discharged in time through the metering valve and will accumulate in the receiving chamber. Once the chamber is full, a hydraulic pressure shut-off valve opens, and the fluid in the receiving chamber is discharged into the abnormal flow chamber at a predetermined flow rate. This continues until the accumulated fluid flow rate decreases, and the fluid in the receiving chamber can no longer accumulate enough hydraulic pressure to open the pressure shut-off valve, at which point the pressure shut-off valve will close. Nurses can visually assess the increased fluid in the abnormal flow chamber and anticipate potential dangers by observing the magnitude of the abnormal increase in fluid accumulation, and then take appropriate action.

Detailed Implementation

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-4 As shown, a thoracic surgery nursing anti-blockage drainage monitoring system includes a control body 1, which includes a snap-fit ​​station and a suction pump with its output end located at the snap-fit ​​station. The system is characterized in that a liquid storage tank 2 is snapped onto the snap-fit ​​station, and the input end of the drainage tube 4 provided on the liquid storage tank 2 is inserted into the output end.

[0040] The liquid storage tank 2 is equipped with a partition plate assembly 3, which divides the interior of the liquid storage tank 2 into an abnormal flow chamber 21, a constant flow chamber 22, and a receiving chamber 23, wherein:

[0041] A metering valve 100 is fixedly connected between the liquid receiving chamber 23 and the constant flow chamber 22;

[0042] A pressure on / off valve 200 is fixedly connected between the abnormal flow chamber 21 and the liquid receiving chamber 23. The pressure on / off valve 200 is used to connect the two after the liquid receiving chamber 23 reaches a predetermined hydraulic pressure.

[0043] Specifically, in this embodiment, the liquid storage chamber 2 is a transparent plastic part, which makes it easy for nurses to visually observe the liquid state in the abnormal flow chamber 21, the constant flow chamber 22 and the receiving chamber 23.

[0044] Secondly, in order for nurses to detect the increase in liquid in the abnormal flow chamber 21 visible to the naked eye, a scale line is set on the outer wall of the abnormal flow chamber 21, and a colored float plate 24 is also placed for use in conjunction.

[0045] Furthermore, in the embodiments, the pressure on / off valve 200 is composed of a hydraulic sensor and a solenoid valve, or a level sensor and a solenoid valve, or a control unit composed of an electronic control valve body and control elements known to those skilled in the art.

[0046] In the above technology, the drainage fluid first enters the receiving chamber 23, and then is guided into the constant flow chamber 22 by the fixedly connected metering valve 100. If the accumulated fluid increases, the fluid in the receiving chamber 23 cannot be discharged in time through the metering valve 100 and will accumulate in the receiving chamber 23. After the chamber is full, the pressure shut-off valve 200 is opened under hydraulic pressure, and the fluid in the receiving chamber 23 is discharged into the abnormal flow chamber 21 at a predetermined flow rate. Until the accumulated fluid flow rate decreases, and the fluid in the receiving chamber 23 can no longer accumulate enough hydraulic pressure to open the pressure shut-off valve 200, the pressure shut-off valve 200 will close. The nurse can visually assess the danger by observing the increase in fluid in the abnormal flow chamber 21 and the magnitude of the abnormal increase in fluid accumulation, and then take appropriate action.

[0047] As a further embodiment of the present invention, the drainage tube 4 consists of a number of flexible tubes 41 and a stainless steel tube 42 that connects two flexible tubes 41 in series; the stainless steel tube 42 is provided with inclined elastic rectangular columns 43 that abut against each other at one end, and the gap between the multiple elastic rectangular columns 43 forms a channel 431 for the passage of accumulated fluid.

[0048] Specifically, in this embodiment, when the accumulated liquid passes through the channel 431, it is intercepted and separated by multiple elastic rectangular pillars 43, thereby preventing blockage and accumulation.

[0049] It should be noted that the elastic rectangular column 43 in the embodiment is a hollow structure.

[0050] As another embodiment of the present invention, the inner wall of the stainless steel tube 42 is provided with a reciprocating groove 44, and a rotating sleeve 441 is rotatably provided in the reciprocating groove 44. A V-shaped component 442 is provided in the rotating sleeve 441 by bending a piece of metal plate.

[0051] The two ends of V-component 442 are not on the same plane, and the included angle between them is 35°-42°;

[0052] The number of V-components 442 is not less than three to form a spiral cone frame. A blade 45 is provided on the top of the inner side of the spiral cone frame. The blade 45 is disturbed by the flowing liquid, causing the spiral cone frame to rotate circumferentially.

[0053] Specifically, in this embodiment, the accumulated liquid flows and drives the blade 45 to rotate the V component 442. With the sliding cooperation of the rotating sleeve 441 and the reciprocating groove 44, it moves up and down along the axial direction of the stainless steel tube 42, thereby creating a pulling effect and thus avoiding blockage of the channel 431.

[0054] As a further preferred embodiment of the present invention, vertical plates 46 that can move up and down within the channel 431 are respectively provided at both ends of the V component 442.

[0055] Furthermore, the vertical plate 46 is tangent to one of the elastic rectangular columns 43 constituting the channel 431, and the ends of the multiple elastic rectangular columns 43 separate as it moves downward.

[0056] Specifically, in the embodiment, when the V component 442 moves up and down along the axial direction of the stainless steel tube 42, the vertical plate 46 will separate from the multiple opposing elastic rectangular columns 43, thereby avoiding blockage of the channel 431.

[0057] As another embodiment of the present invention, the pressure on / off valve 200 includes a mounting base 5 mounted on the partition plate assembly 3 and a pipe body 6 fixedly mounted on the mounting base 5;

[0058] The outer wall of the tube body 6 is provided with a ring 61, which is located inside the mounting base 5, and a first retaining spring 52 is provided between the two.

[0059] The tube body 6 is rotatably provided with a cap 62 inside the liquid receiving chamber 23. The port of the tube body 6 is provided with a blocking block 63 that forms a blocking engagement with the cap 62. The flipping direction of the cap 62 is towards the tube body 6.

[0060] A floating island 64 is provided inside the pipe body 6, and a connecting valve core 65 is slidably provided on the floating island 64. The connecting valve core 65 moves synchronously with the cover 62.

[0061] A second retaining spring 66 is provided between the floating island 64 and the connecting valve core 65.

[0062] Specifically, after the liquid in the receiving chamber 23 in the embodiment is full, the hydraulic pressure pushes the cap 62 toward the inside of the pipe body 6, thereby contacting the seal. At this time, the liquid in the receiving chamber 23 will flow into the pipe body 6, and then enter the abnormal flow chamber 21 along the connecting valve core 65.

[0063] When the liquid in the receiving chamber 23 cannot accumulate enough hydraulic pressure, the second retaining spring 66 pushes the cover 62 back to its original position and seals it.

[0064] As another embodiment of the present invention, a rotating member 70 is rotatably provided inside the tube body 6, and a first rod 71 with one end rotatably connected to the rotating member 70 is rotatably provided on the cover 62.

[0065] A second rod 72 is slidably disposed on the connecting valve core 65, one end of which is rotatably connected to the rotating component 70.

[0066] Furthermore, the length of the first rod 71 is a multiple of the length of the second rod 72.

[0067] Specifically, in the embodiment, when the cap 62 moves toward the inside of the tube 6, it is presumed that the first rod 71 drives the rotating member 70 to rotate, which in turn drives the second rod 72 to separate the connecting valve core 65 from the cap 62, thereby increasing the amount of liquid passing through the connecting valve core 65.

[0068] As a further embodiment of the present invention, a guide seat 67 is provided inside the tube body 6, and the end of the connecting valve core 65 is located in the central hole of the guide seat 67; a V-shaped lever 80 is symmetrically arranged in the central hole, one end of the V-shaped lever 80 abuts against the end of the connecting valve core 65, and the other end is inserted into a guide rod 81 that is radially slidably arranged inside the guide seat 67. The guide rod 81 is used to push the sliding push block 82 on the tube body 6 to move, and can push the first resisting spring 52; an elastic tension member 83 is provided between the push block 82 and the guide seat 67.

[0069] Specifically, in the embodiment, when the connecting valve core 65 is pushed and moved, the V-shaped lever 80 deflects, causing the guide rod 81 to push the push block 82 to squeeze the first resisting spring 52.

[0070] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
