Description

Technical Field

[0001] The present invention belongs to the technical field of drainage devices, and in particular relates to a thoracic surgery nursing drainage device. Background Art

[0002] After thoracic surgery, there may be residual cavities in the thoracic cavity. If there is gas or fluid accumulation in the cavity, it will affect the healing of the wound. The drainage device can drain these substances, gradually reduce the residual cavity in the thoracic cavity, promote the adhesion of tissues in the thoracic cavity, and create favorable conditions for wound healing. For example, a thoracic surgery drainage device proposed in the patent publication number CN111467583B.

[0003] When the existing drainage device is in use, when the patient's body position is improper, or the external objects compress the drainage tube. For example, when a bedridden patient turns over, the drainage tube may be inadvertently pressed under the body, which may cause the drainage tube to deform and twist, hinder the outflow of the drainage fluid, and affect the normal operation of the drainage device;

[0004] In addition, the basic principle of thoracic cavity drainage is to rely on the action of gravity to make the gas, liquid, etc. in the thoracic cavity flow naturally downward along the drainage tube and be discharged out of the body. And in order to ensure that the accumulated fluid and gas in the thoracic cavity can smoothly flow into the drainage device under the action of gravity, medical staff usually place the drainage device at a position lower than the knees. For example, during closed thoracic drainage, the liquid in the thoracic cavity flows along the drainage tube to the water seal bottle at a lower position under the action of gravity. If the position of the drainage device is too high, the liquid cannot flow out normally, and even may flow back into the thoracic cavity, causing serious problems such as infection. When the patient needs to undergo other examinations and get up and walk during the drainage process, the drainage device needs to be lifted, so there is a problem that the too-high lifting of the drainage device affects the drainage effect.

[0005] Therefore, a thoracic surgery nursing drainage device is proposed to solve the above problems. Summary of the Invention

When using the drainage device, the compressive resistance and anti-twisting deformation ability of the drainage tube 401 can be improved, thereby avoiding the situation that the patient's body position is improper or the drainage tube 401 is pressed and twisted by foreign objects, which affects the normal working ability of the drainage device and ensures the safety of the patient when using the drainage device;

[0035] The detection component 9 is arranged on the side wall of the device body 1 and is used for detecting the placement height of the device body 1.

The conductive plate 20 on the right side is electrically connected to the PLC controller 2, and the conductive plate 20 on the left side is electrically connected to an external power supply. A conduction plate 21 is inserted into the side wall of the partition plate 13. When the patient uses the drainage device and needs to get up and walk, the height of the drainage device can be automatically detected during the process of lifting the drainage device. When it is found that the placement position of the drainage device is too high, the patient can be reminded in time, so that the drainage device has enough gravity to drain the accumulated fluid in the chest cavity, and the problem that the accumulated fluid will flow back and cause infection due to the too high placement of the drainage device is also avoided;

[0036] A protection component 22 is arranged at the upper end of the replaceable drainage component 4 to prevent the replaceable drainage component 4 from being over-stretched; a fixing component 29 is arranged above the protection component 22 to prevent the drainage device from detaching from the patient's wound. The protection component 22 includes a U-shaped tube 221 connected to the upper end of the uppermost drainage tube 401. The U-shaped tube 221 is connected to the uppermost drainage tube 401 through a threaded connection mechanism. A plug-in tube 222 is fixedly connected to the left end of the U-shaped tube 221.

A horizontal tube 35 is fixedly connected between the air pressure box 32 and the annular suction cup 31. A spring is fixedly connected between the piston seat 34 and the air pressure box 32. After the drainage device is inserted into the patient's body, the insertion end can be fixed on the patient's body surface. At the same time, after the drainage device is pulled by an external force, an alarm can be issued in time, thus avoiding the problem that the end of the drainage device detaches from the patient's body and affecting the patient's physical health.

[0037] A bent plate 36 is fixedly connected to the right side wall of the air pressure box 32. The bent plate 36 is of an inverted L-shaped structure. A positioning groove is formed in the inner wall of the bent plate 36, and a positioning plate 37 is inserted into the positioning groove. A plurality of ratchet teeth 38 are fixedly connected to the side walls of the positioning plate 37 and the U-shaped rod 33 facing each other. A pull rod 39 is fixedly connected to the side wall of the positioning plate 37. The end of the pull rod 39 extending out of the positioning groove is fixedly connected to a pull plate 40.

[0038] The side wall of the silica gel disc 291 is fixedly connected with a locking cover 41. The upper end of the scale plate 27 is located inside the locking cover 41. The side wall of the locking cover 41 is threadedly connected with a threaded pin 42. The upper end of the threaded pin 42 is fixedly connected with a screwing plate 43. The lower end of the threaded pin 42 is rotatably connected with a plug plate 44. The lower end of the plug plate 44 is fixedly connected with a plug 45, which further improves the connection strength between the insertion tube 222 and the silica gel disc 291.

[0039] A optical signal generator 46 is fixedly connected to the inner wall of the upper inner elastic plate 5, and an optical signal receiver 47 is fixedly connected to the inner wall of the lower inner elastic plate 5. The optical signal receiver 47 is electrically connected to the PLC controller 2. A water tank 48 is fixedly connected to the side wall of the device body 1. A pump 49 is fixedly communicated with the side wall of the water tank 48. The liquid outlet end of the pump 49 is fixedly communicated with a dredging pipe 50. A hydraulic sensor 51 is arranged in the dredging pipe 50. The upper end of the dredging pipe 50 is communicated with the insertion tube 222. A first one-way valve 52 is arranged in the dredging pipe 50, and a second one-way valve 53 is arranged in the insertion tube 222, which can detect which drainage tube 401 is blocked.

[0040] The operating principle of the present invention is described as follows: Medical staff use a puncture needle to puncture and then withdraw from the patient's chest cavity (for thoracic cavity fluid drainage, the 7th - 9th intercostal space along the scapular line or the 7th - 8th intercostal space along the posterior axillary line is generally selected). Then, the left end of the insertion tube 222 is inserted into the puncture hole (the left end of the insertion tube 222 has passed through the insertion opening 292 in advance). Next, the silicone disc 291 is placed on the patient's chest cavity to align the insertion opening 292 with the patient's puncture hole. Then, the silicone disc 291 is fixed at the patient's chest cavity by the magic - tape strap 30. Then, the medical staff continue to insert the left end of the insertion tube 222 into the puncture hole. During the movement of the left end of the insertion tube 222, the scale plate 27 will be driven to move leftward together by the fixing ring 23 on the left side. During the leftward movement of the scale plate 27, it will be inserted into the locking cover 41. By observing the position where the scale plate 27 is inserted into the locking cover 41, the depth of the insertion tube 222 inserted into the puncture hole can be judged (generally 5 - 7 cm). When the insertion tube 222 stops moving, the medical staff can rotate the screwing plate 43. The screwing plate 43 will drive the threaded pin 42 to rotate together. Through the threaded cooperation between the threaded pin 42 and the locking cover 41, the insertion plate 44 can be driven to move downward (the insertion plate 44 is rotationally connected to the threaded pin 42). And during the downward movement of the insertion plate 44, the scale plate 27 will be penetrated by the insertion pin 45, thereby fixing the scale plate 27 in the locking cover 41, ensuring the connection strength between the insertion tube 222 and the silicone disc 291. Then, the medical staff pull the U - shaped rod 33 downward. The left end of the U - shaped rod 33 will drive the piston seat 34 to move downward, reducing the air pressure above the piston seat 34. At the same time, the air - pressure box 32 is communicated with the annular suction cup 31 through the horizontal tube 35, and the air pressure inside the annular suction cup 31 will also be reduced, causing the annular suction cup 31 to adsorb on the surface of the patient's skin, further strengthening the connection strength between the silicone disc 291 and the patient's chest - cavity skin. And during the downward movement of the U - shaped rod 33, through the mutual cooperation between the ratchet teeth 38 between the U - shaped rod 33 and the positioning plate 37, the position of the U - shaped rod 33 can be fixed, and then the drainage device can be installed to drain the fluid in the patient's chest cavity;

[0041] When the patient turns over subsequently, the anti-pressure ability of the internal drainage tube 401 can be improved through the provided protective ring 6, and at the same time, the anti-twisting ability of the drainage tube 401 can be improved through the provided elastic sheet 7, thereby avoiding improper body position of the patient or external object pressing and twisting the drainage tube 401, which affects the normal working ability of the drainage device, ensuring the safety of the patient when using the drainage device. And when the drainage tube 401 is pulled, the drainage tube 401 will drive the right end of the U-shaped tube 221 and the horizontal box 24 to move to the right together, and the moving seat 25 inside the horizontal box 24 will move to the left under the action of the pull rope 26. When the pulling degree of the drainage tube 401 is relatively large, the moving seat 25 will squeeze the control switch 28, and the control switch 28 will control the buzzer inside the PLC controller 2 to emit a "dong dong dong" prompt sound to remind the surrounding people to pay attention and avoid pulling out the insertion tube 222 from the puncture port;

[0042] After a certain section of the drainage tube 401 is blocked, the liquid in the drainage tube 401 will solidify, thereby making the light transmission performance of the drainage tube 401 worse (for example, inflammatory reactions or tissue damage will cause cell necrosis and shedding in the thoracic cavity, generating cell debris, and these debris will flow with the drainage fluid and are likely to accumulate inside the drainage tube 401, especially at smaller or curved pipe diameters, gradually forming blockages). The light source signal emitted by the light signal generator 46 will be blocked and weakened by the blockage. When the light signal receiver 47 detects that the light source becomes weak, it will control the lamp beads on the surface of the corresponding inner elastic plate 5 to work through the PLC controller 2 (the lamp beads are drawn in Figure 4 but not marked), and at the same time, the PLC controller 2 will also control the pump 49 to work. The pump 49 will transport normal saline to the right end of the insertion tube 222 through the dredging tube 50 and the first one-way valve 52. Under the action of the second one-way valve 53, the normal saline will not enter the patient's thoracic cavity through the insertion tube 222. The normal saline will be transported to multiple drainage tubes 401 through the U-shaped tube 221. When the blockage inside the drainage tube 401 is not serious, the normal saline can wash away the blockage. When the blockage is difficult to clean, the water pressure inside the drainage tube 401 will continue to increase. When the water pressure inside the drainage tube 401 reaches the set threshold (about 100 mmHg) detected by the provided hydraulic sensor 51, the hydraulic sensor 51 will control the pump 49 to stop working through the PLC controller 2. At the same time, the PLC controller 2 will also control the buzzer inside to work with a "di di di" prompt sound to remind the medical staff that they need to replace the drainage tube 401 with serious blockage and difficult dredging. The medical staff can quickly find the corresponding drainage tube 401 through the lamp beads, then separate the buckle assembly between the inner elastic plate 5 and the outer elastic plate 8, and then separate the protective ring 6 and the positioning ring 402, and then rotate the corresponding drainage tube 401 to rotate and remove the drainage tube 401, and replace it with a new drainage tube 401. Then, install multiple protective rings 6 on the outside of the new drainage tube 401 through the buckle assembly to solve the problem of blockage of the drainage tube 401;

[0043] When the patient needs to get up and move, the patient needs to lift the handle to pull the device body 1, and the device body 1 will leave the ground. The detection rod 92 inside the detection cylinder 91 will drive the ball 10 to move downward under the action of the spring elasticity. When the height of the device body 1 exceeds the patient's knee, the four detection rods 92 will drive the lifting plate above to squeeze the trigger switch 11. The trigger switch 11 is electrically connected to the corresponding electromagnet block 19 through the PLC controller 2. The four electromagnet blocks 19 will all generate magnetic forces and attract the permanent magnet blocks 18 above, so that the four permanent magnet blocks 18 drive the metal plate 17 to move downward together through the vertical rod 16. The metal plates 17 on the left and right sides will contact the conductive plates 20 on both sides, and the four metal plates 17 will also contact the three conduction plates 21. The conductive plate 20 on the left is electrically connected to the external power supply, and the conductive plate 20 on the right is electrically connected to the PLC controller 2. When the four metal plates 17 move downward together to the set position, the external current will be transmitted to the PLC controller 2 through the four metal plates 17, the three conduction plates 21 and the conductive plate 20 on the right. The PLC controller 2 will control the buzzer to emit a "tick-tick-tick" prompt sound to remind the patient to lower the position of the device body 1, so that the drainage device has enough gravity to drain the effusion in the chest cavity, and also avoids the problem that if the drainage device is placed too high, the effusion will flow back and cause infection.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
