Description

Technical Field

[0001] The invention relates to the technical field of drainage devices, and in particular to a drainage monitoring system for preventing blockage in thoracic surgery nursing. Background Art

[0002] Thoracic surgery patients often need drainage monitoring after surgery, which plays an important role in preventing postoperative complications and ensuring patient recovery. Drainage monitoring can help nursing staff to promptly detect and deal with possible complications such as hematoma and infection, maintain smooth drainage in the chest cavity, avoid infection at the drainage site, and monitor changes in drainage volume to understand the patient's condition. Through effective drainage monitoring, nursing staff can better guide patient rehabilitation and adjust nursing measures in a timely manner, reduce the risk of complications, and improve the quality of patient recovery.

[0003] At present, chest drainage is a commonly used treatment method in the field of thoracic surgery. During treatment, the gas and liquid in the patient's chest cavity need to be discharged from the body in time. The existing medical technology still has the following defects: since the waste liquid in the chest cavity sucked out by the drainage tube may contain solid blocks, it is very likely to be blocked. The tube needs to be pulled out of the patient's body for unblocking, which aggravates the patient's pain and is troublesome to operate. Therefore, some alarm devices are usually set to remind medical staff to solve the blockage problem in time, but this process is easy to be ignored and the problem cannot be solved in time. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a drainage monitoring system for thoracic surgery nursing to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Two drainage tubes arranged side by side serve as a main tube and a spare tube. The main tube is first connected with the connecting tube through the plug-in end of the installation box, and the chest gas or liquid is sent into the water tank through the negative pressure effect. When the main tube is blocked, it is quickly switched to the spare tube to be connected to the connecting tube, which can maintain the drainage effect to a certain extent and reduce the patient's pain.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a drainage monitoring system for thoracic surgery nursing anti-blocking, comprising a water tank, a switching component is installed on the front end surface of the water tank, the switching component comprises a mounting box, two plug-in ends are symmetrically fixed at the middle position inside the mounting box, two drainage tubes are plugged into the front end surface of the mounting box, the two drainage tubes are arranged side by side and sleeved on the two plug-in ends at the front end of the mounting box, a connecting tube is plugged into the rear end surface of the mounting box, one end of the connecting tube is connected to one group of plug-in ends of the mounting box, and the other end of the connecting tube is connected to the inside of the water tank, the front end of the mounting box The top and bottom of the first and rear ends are provided with sliding frames, and a sliding plate is slidably connected in the sliding frame, and the four groups of sliding plates are on the same section, a second clamping block is fixed on the surface of the two sliding plates at the rear end of the installation box, and a first clamping block is fixed on the surface of the two sliding plates at the front end of the installation box, the first clamping block is clamped on the outer surface of the drainage tube, the front end of the connecting tube is fixed to the inner wall of the second clamping block, and mounting components are equidistantly provided on the surfaces of the two drainage tubes, and the mounting components include a first soft frame and a second soft frame, and the first soft frame and the second soft frame are equidistantly fixed on the surfaces of the two drainage tubes, and the first soft frame and the second soft frame are merged into a whole.

[0006] Furthermore, a display screen is installed on the top of the water tank, and a negative pressure device is installed on the side of the water tank. An alarm light is fixedly installed on the side of the water tank at the top of the negative pressure device.

[0007] Furthermore, the switching assembly also includes an arc track, and the top and bottom inner walls of the front and rear ends of the installation box are fixed with arc tracks, and the arc track is slidably sleeved with a buckle frame corresponding to the position of the sliding frame, and telescopic plates are rotatably installed on both sides of the buckle frame through a rotating shaft, and the extended end of the telescopic plate is rotatably connected to the sliding frame through a rotating shaft.

[0008] Furthermore, a bidirectional electric push rod is fixed at the top and bottom of the middle position of the installation box, and the extended ends of the bidirectional electric push rod are respectively fixedly connected to the sliding frames on both sides.

[0009] Furthermore, one end of the two sets of sliding frames at the front and rear ends of the installation box is provided with a vertical plate, and the vertical plate slides along the inner wall of the installation box, the top and bottom of the vertical plate are slidably plugged with plug plates, and the plug plates are fixedly connected to the upper and lower sets of sliding frames respectively.

[0010] Furthermore, a slide groove is provided on the front side of the vertical plate, and two sliders are symmetrically slidably installed inside the slide groove. A connecting rod is rotatably installed on the outer surface of the slider via a rotating shaft, and the other end of the connecting rod is rotatably connected to the slide plate via the rotating shaft.

[0011] Furthermore, an inclined block is fixed on the outer surface of the sliding block, and a triangular plate is fixed on the inner walls of the front and rear ends of the installation box, and the inclined block slides along the upper and lower inclined edges of the triangular plate.

[0012] Furthermore, contact switches are fixed on both sides of the middle position of the installation box corresponding to the initial positions of the first clamping block and the second clamping block, and the contact switches are respectively in compression contact with the first clamping block and the second clamping block.

[0013] Furthermore, a movable opening is provided on the back side of the installation box, and a movable plate is slidably connected in the movable opening, and the connecting pipe is slidably inserted in the movable plate.

[0014] Furthermore, the installation component also includes an insertion block, the top and bottom of the second soft frame are fixed with the insertion blocks, the first soft frame is provided with a slot at the position corresponding to the insertion block, and the insertion block is slidably inserted into the first soft frame, the first soft frame is fixed with connecting plates on both sides of the insertion block, the surfaces of the connecting plate and the insertion block are provided with insertion holes in the same straight line, an elastic rope passes through the insertion hole, one end of the elastic rope is fixedly connected to a drainage tube on one side, and the other end of the elastic rope is clamped inside the first clamping block.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention passes an elastic rope through the position of the plug block and the connecting plate, so as to maintain the connection relationship between the first soft frame and the second soft frame. The elastic rope runs through the entire installation assembly of the drainage tube, and after one end of the elastic rope is clamped by the first clamp block, the stability of the two drainage tubes arranged side by side can be maintained without loosening. When the first clamp block switches from the main tube position to the spare tube position, the elastic rope is not restricted and is separated from the plug hole of the plug block and the connecting plate by its own elastic force. At this time, the first soft frame and the second soft frame can be separated by plugging and unplugging, so as to remove the blocked main tube and prevent infection to the patient.

[0017] 2. In the present invention, when the slide frame moves outward along the arc-shaped slide rail, the vertical plate will also slide synchronously along the inner wall of the installation box because the plug plates at the upper and lower ends are connected to the two slide frames. Because the inclined block of the slider is in sliding contact with the hypotenuse of the triangular plate, when the vertical plate moves outward, the inclined block cooperates with the inclined surface of the hypotenuse of the triangular plate to make the slider move upward along the slide groove, and the slide plate is pushed to the other end of the slide frame through the connecting rod. At this time, the spare pipe can be connected and used. When connecting the spare pipe, because the slide frame still needs to move backward, the inclined block will be separated from the triangular plate, and because there is no elasticity between the plug plate and the vertical plate, the connecting rod will not pull the slide plate back to its original position.

[0018] 3. The present invention is connected to the sliding frame through a buckle frame and a telescopic plate. Due to the arc shape of the arc-shaped slide rail itself, the initial position is the lowest point. During the outward movement, the connection tube and the plug-in end can be easily separated by plugging and unplugging. At the same time, the clamping effect of the first clamp block and the second clamp block on the drainage tube and the connecting tube is released. The second clamp block drives the connecting tube to move to the plug-in end on the other side. The connecting tube slides along the moving opening through the moving plate, and the first clamp block directly switches to the position of the spare drainage tube. After the sliding frame returns to the lowest point of the arc-shaped slide rail, the first clamp block and the second clamp block clamp the drainage tube and the connecting tube respectively to maintain stability during the negative pressure drainage process.

[0019] 4. Compared with the prior art, the present invention uses two drainage tubes arranged side by side as the main tube and the spare tube. The main tube is first connected with the connecting tube through the plug end of the installation box, and the chest gas or liquid is sent into the water tank through the negative pressure effect. When the main tube is blocked, it is quickly switched to the spare tube to be connected with the connecting tube, which can maintain the drainage effect to a certain extent and reduce the patient's pain.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] See also Figures 1 to 8The present invention provides a technical solution: a drainage monitoring system for thoracic surgery nursing anti-blocking, comprising a water tank 1, a switching component 2 is installed on the front end surface of the water tank 1, the switching component 2 comprises an installation box 21, two plug-in ends 27 are symmetrically fixed at the middle position inside the installation box 21, two drainage tubes 3 are plugged on the front end surface of the installation box 21, the two drainage tubes 3 are arranged side by side and sleeved on the two plug-in ends 27 at the front end of the installation box 21, a connecting pipe 14 is plugged on the rear end surface of the installation box 21, one end of the connecting pipe 14 is connected to one group of plug-in ends 27 of the installation box 21, and the other end of the connecting pipe 14 is connected to the inside of the water tank 1, a sliding frame 25 is provided on the top and bottom of the front and rear ends of the installation box 21, and a sliding plate 26 is slidably connected in the sliding frame 25, and the four groups of the sliding plates 26 are on the same section, and a second clamping block 23 is fixed on the surface of the two sliding plates 26 at the rear end of the installation box 21, and the surface of the two sliding plates 26 at the front end of the installation box 21 A first clamping block 22 is fixed on the top, and the first clamping block 22 is clamped on the outer surface of the drainage tube 3. The front end of the connecting tube 14 is fixed to the inner wall of the second clamping block 23. The surfaces of the two drainage tubes 3 are equidistantly provided with mounting components 4, and the mounting components 4 include a first soft frame 41 and a second soft frame 42. The surfaces of the two drainage tubes 3 are respectively equidistantly fixed with the first soft frame 41 and the second soft frame 42, and the first soft frame 41 and the second soft frame 42 are combined into a whole. When using the device, the two drainage tubes 3 are spliced ​​together through the mounting component 4, one of which is used for drainage and the other is used as a spare. The drainage tube 3 is connected to the connecting tube 14 by switching the first clamping block 22 and the second clamping block 23 in the component 2, and the gas or liquid in the patient's chest cavity is extracted by the negative pressure effect. When the main drainage tube 3 is blocked, the switching component 2 switches to the spare drainage tube 3 to be connected to the connecting tube 14 for continued use, and sends out an alarm in time, so as to maintain a certain drainage effect before the staff finds it.

[0031] In this embodiment, a display screen 11 is installed on the top of the water tank 1, and a negative pressure device 13 is installed on the side of the water tank 1. An alarm light 12 is fixedly installed on the side of the water tank 1 at the top of the negative pressure device 13. Contact switches 218 are fixed on both sides of the middle position of the installation box 21 corresponding to the initial positions of the first clamp block 22 and the second clamp block 23, and the contact switch 218 is squeezed and contacted with the first clamp block 22 and the second clamp block 23 respectively. The display screen 11, negative pressure device 13 and alarm light 12 on the water tank 1 are all prior arts. The technical method of CN107899099B can be referred to. When the main pipe is in use, the first clamp block 22 and the second clamp block 23 are both in contact with the contact switch 218. When the main pipe is blocked and the drainage tube 3 is switched for use, the first clamp block 22 and the second clamp block 23 are no longer in contact with the contact switch 218. At this time, the contact switch 218 transmits an electrical signal to the alarm light 12, which has an early warning effect.

[0032] In this embodiment, the switching component 2 also includes an arc track 24, and the top and bottom inner walls of the front and rear ends of the installation box 21 are fixed with arc tracks 24. The arc track 24 is slidably sleeved with a buckle frame 211 corresponding to the position of the slide frame 25. Telescopic plates 212 are rotatably installed on both sides of the buckle frame 211 through a rotating shaft, and the extended end of the telescopic plate 212 is rotatably connected to the slide frame 25 through a rotating shaft. A two-way electric push rod 213 is fixed at the top and bottom of the middle position of the installation box 21, and the extended ends of the two-way electric push rod 213 are respectively fixedly connected to the slide frames 25 on both sides. A pressure sensor for detecting the internal pressure of the pipeline is also installed inside the installation box 21. When a constant pressure is detected, it indicates that a blockage has occurred, and the two-way electric push rod 213 pushes the slides on both sides. The frame 25 moves along the arc-shaped slide rail and is connected to the slide frame 25 through the buckle frame 211 and the telescopic plate 212. Because of the arc shape of the arc-shaped slide rail itself, the initial position is the lowest point. During the outward movement, the connection tube 14 can be easily plugged in and out of the plug-in end 27, and at the same time, the clamping effect of the first clamp 22 and the second clamp 23 on the drainage tube 3 and the connection tube 14 is released. The second clamp 23 drives the connection tube 14 to move to the plug-in end 27 on the other side. The connection tube 14 slides along the moving port 29 through the moving plate 210, and the first clamp 22 directly switches to the position of the spare drainage tube 3. After the slide frame 25 returns to the lowest point of the arc-shaped slide rail, the first clamp 22 and the second clamp 23 clamp the drainage tube 3 and the connection tube 14 respectively to maintain stability during the negative pressure drainage process.

[0033] In this embodiment, one end of the two groups of sliding frames 25 at the front and rear ends of the installation box 21 is provided with a vertical plate 214, and the vertical plate 214 slides along the inner wall of the installation box 21, the top and bottom of the vertical plate 214 are slidably plugged with plug plates 215, and the plug plates 215 are respectively fixedly connected to the upper and lower groups of sliding frames 25, a sliding groove 216 is provided on the front side of the vertical plate 214, and two sliding blocks 219 are symmetrically slidably installed inside the sliding groove 216, a connecting rod 217 is rotatably installed on the outer surface of the sliding block 219 through a rotating shaft, and the other end of the connecting rod 217 is rotatably connected to the sliding block 26 through a rotating shaft, and an inclined block 220 is also fixed on the outer surface of the sliding block 219, a triangular plate 28 is fixed on the inner wall of the front and rear ends of the installation box 21, and the inclined block 220 slides along the upper and lower oblique edges of the triangular plate 28, a moving opening 29 is provided on the back side of the installation box 21, and a moving plate 210 is slidably connected in the moving opening 29, and the connecting pipe 14 The sliding plate 214 is inserted in the movable plate 210. When the slide frame 25 moves outward along the arc slide rail, the vertical plate 214 will slide synchronously along the inner wall of the installation box 21 because the plug plates 215 at the upper and lower ends are connected to the two slide frames 25. Because the inclined block 220 of the slider 219 is in sliding contact with the hypotenuse of the triangular plate 28, when the vertical plate 214 moves outward, the inclined block 220 cooperates with the inclined surface of the hypotenuse of the triangular plate 28 to make the slider 219 move upward along the slide groove 216, and the slide plate 26 is pushed to the other end of the slide frame 25 through the connecting rod 217. At this time, the spare pipe can be connected and used. When connecting the spare pipe, because the slide frame 25 still needs to move backward, the inclined block 220 will separate from the triangular plate 28. Because there is no elasticity between the plug plate 215 and the vertical plate 214, the connecting rod 217 will not pull the slide plate 26 back to its original position. There is a certain gap between the triangular plate 28 and the inner wall of the installation box 21, which can be used for the movement of the vertical plate 214.

[0034] In this embodiment, the installation component 4 also includes an insert block 43, the top and bottom of the second soft frame 42 are fixed with the insert block 43, the first soft frame 41 is provided with a slot at a position corresponding to the insert block 43, and the insert block 43 is slidably inserted into the first soft frame 41, and the first soft frame 41 is fixed with connecting plates 44 on both sides of the insert block 43, and the surfaces of the connecting plate 44 and the insert block 43 are provided with plug holes in the same straight line, and an elastic rope 45 passes through the plug hole, one end of the elastic rope 45 is fixedly connected to the drainage tube 3 on one side, and the other end of the elastic rope 45 is clamped inside the first clamping block 22. After the two hoses are plugged in through the first soft frame 41 and the second soft frame 42, An elastic rope 45 passes through the position of the plug block 43 and the connecting plate 44, so as to maintain the connection relationship between the first soft frame 41 and the second soft frame 42. The elastic rope 45 runs through the entire installation assembly 4 of the drainage tube 3, and after one end of the elastic rope 45 is clamped by the first clamp block 22, the stability of the two drainage tubes 3 arranged side by side can be maintained without loosening. When the first clamp block 22 switches from the main pipe position to the spare pipe position, the elastic rope 45 is not restricted and detaches from the jacks of the plug block 43 and the connecting plate 44 by its own elastic force. At this time, the first soft frame 41 and the second soft frame 42 can be separated by plugging and unplugging, so as to remove the blocked main pipe and prevent infection to the patient.

[0035] When the device is used, after the two hoses are plugged into the first soft frame 41 and the second soft frame 42, an elastic rope 45 is passed through the position of the plug block 43 and the connecting plate 44, so as to maintain the connection relationship between the first soft frame 41 and the second soft frame 42. The elastic rope 45 runs through the entire installation assembly 4 of the drainage tube 3, and after one end of the elastic rope 45 is clamped by the first clamping block 22, the stability of the two drainage tubes 3 arranged side by side can be maintained without loosening. When the first clamping block 22 is switched from the main pipe position to the standby pipe position, the elastic rope 45 is not restricted and is separated from the plug hole of the plug block 43 and the connecting plate 44 by its own elastic force. At this time, the first clamping block 22 can be manually connected by plugging and unplugging. The soft frame 41 and the second soft frame 42 are separated, so that the blocked main pipe is removed to prevent infection to the patient. One of them is used for drainage and the other is reserved. The drainage pipe 3 is connected with the connecting pipe 14 by the first clamp block 22 and the second clamp block 23 in the switching component 2, and the gas or liquid in the patient's chest cavity is extracted by the negative pressure effect. When the pressure is detected to be constant, it means that blockage has occurred. The two-way electric push rod 213 pushes the sliding frame 25 on both sides to move along the arc-shaped slide rail, and is connected to the sliding frame 25 through the buckle frame 211 and the telescopic plate 212. Because the arc-shaped slide rail itself has an initial position at the lowest point, the connecting pipe 14 can be easily connected during the outward movement. The plug-in and unplugging of the plug-in end 27 releases the clamping effect of the first clamp block 22 and the second clamp block 23 on the drainage tube 3 and the connecting tube 14. The second clamp block 23 drives the connecting tube 14 to move to the plug-in end 27 on the other side. The connecting tube 14 slides along the moving opening 29 through the moving plate 210, and the first clamp block 22 is directly switched to the position of the standby drainage tube 3. After the slide frame 25 returns to the lowest point of the arc-shaped slide rail, the first clamp block 22 and the second clamp block 23 clamp the drainage tube 3 and the connecting tube 14 respectively to maintain stability during the negative pressure drainage process. When the slide frame 25 moves outward along the arc-shaped slide rail, the vertical plate 214 is locked because the plug plates 215 at the upper and lower ends are connected to the two slide frames 2 The connection will also slide along the inner wall of the installation box 21 synchronously, because the inclined block 220 of the slider 219 is in sliding contact with the bevel of the triangular plate 28, when the vertical plate 214 moves outward, the inclined block 220 cooperates with the bevel of the bevel of the triangular plate 28 to make the slider 219 move upward along the slide groove 216, and the slide plate 26 is pushed to the other end of the slide frame 25 through the connecting rod 217, and the spare pipe can be connected and used at this time. When connecting the spare pipe, because the slide frame 25 still needs to move backward, the inclined block 220 will be separated from the triangular plate 28, and because there is no elasticity between the plug plate 215 and the vertical plate 214, the connecting rod 217 will not pull the slide plate 26 back to its original position.
