[0001] The utility model relates to a drainage device, in particular to a drainage device. Background Art
[0002] In the department of respiratory medicine, a drainage device usually refers to a device for draining body fluids or gases, which is used to treat secretions such as pleural effusion. For pleural effusion, a pleural drainage tube or a pleural drainage bottle may be used. These devices drain the fluid accumulated in the chest cavity through surgical or puncture operations to relieve the patient's chest pressure and improve the breathing condition. However, there are still some problems with the existing drainage devices:
[0003] 1. At present, most drainage devices adopt postural drainage, that is, gravity drainage. Especially in the department of respiratory medicine, the way of gravity drainage is very common and is often used for the drainage of pleural effusion in thoracic surgery or the drainage of secretions at the affected area. Usually, the drainage bottle is placed under the bed for drainage. However, due to the long drainage pipeline, it is easy to bend and entangle when coiled on the hospital bed, resulting in insufficient gravity, and thus the situation of liquid blockage and non - flow may occur, and there may be a problem of interrupted drainage;
[0004] 2. The drainage bottle is used to store the drained effusion. The effusion has a complex composition and adheres to the bottom and inner wall of the bottle, which is rather troublesome to clean. Moreover, in order to monitor the patient's physical condition, it is necessary to master the drained volume of the effusion, but the drained volume of the effusion in the existing drainage bottle is not easy to read. Summary of the Utility Model

[0007] A gear is rotatably connected to the center of the cylinder cover. A rack is meshed and connected to one side of the gear. A transmission rotating rod is provided at the bottom of the cylinder cover. The top end of the transmission rotating rod is threadedly connected to the bottom end of the gear. A plurality of extended fixing plates are fixedly connected to the side wall of the transmission rotating rod. One side of each extended fixing plate is snap-fitted with a cleaning wiping plate. The bottom of one side of the plurality of cleaning wiping plates is attached to a cleaning scraping plate. A scale plate is fixedly connected to one side wall of the drainage cylinder.

[0008] As a preferred technical solution of the present invention, fixed support plates are fixedly connected to one side wall of the limiting collar and the top of one side wall of the auxiliary cylinder. The limiting vertical plate penetrates through the two fixed support plates, and an adhesive layer is provided at one end of each of the two fixed support plates.

[0011] As a preferred technical solution of the present invention, the rack is slidably connected to one side of the top end of the cylinder cover. A pull ring is fixedly connected to one end of the rack.
[0012] As a preferred technical solution of the present invention, one end of each of the plurality of cleaning scraping plates is snap-fitted to the side wall of the transmission rotating rod. A sliding collection box is snap-fitted to the bottom end of the drainage cylinder. A buckle groove is opened at the bottom end of the sliding collection box.
[0013] As a preferred technical solution of the present invention, the plurality of cleaning wiping plates and the plurality of cleaning scraping plates are respectively attached to the inner wall of the drainage cylinder and the inner wall of the bottom end of the drainage cylinder.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. The utility model sets components such as an auxiliary cylinder and a first-stage drainage tube. During the process of draining the effusion in the patient's chest cavity, when the gravity is insufficient, it cooperates with components such as a motor, a transmission rotating plate, a fixed short column, and a sliding plug, enabling the bottom end of the support arm to drive the sliding plug to reciprocate up and down on the inner wall of the limit collar. When pulling up, it can increase the suction negative pressure in the first-stage drainage tube. When moving down, it can push the effusion drawn into the auxiliary cylinder into the last-stage drainage tube, accelerating the effusion collection process, offsetting the insufficient gravity caused by coiling and winding, ensuring an effective drainage process. When the drainage process is proceeding normally, the motor can be not turned on, and it can be a normal gravity drainage process.
[0016] 2. The utility model sets components such as a first magnetic attraction, a second magnetic attraction, and a floating ball. When the effusion is transported into the drainage cylinder, as the effusion inside it increases, the effusion drives the floating ball to rise, and the floating ball drives the second magnetic attraction to rise. The second magnetic attraction is magnetically adsorbed and connected to the first magnetic attraction. The user can, through the position of the first magnetic attraction block on the scale plate, facilitate the patient to accurately read the effusion volume at this time, thereby facilitating the patient to grasp the relatively accurate drainage progress in real time. When it is necessary to clean the drainage cylinder, it cooperates with components such as an extended fixed plate, a transmission rotating rod, and a cleaning wiping plate, and can quickly pull the pull ring back and forth, so that the rack drives the gear to rotate back and forth. The gear drives the transmission rotating rod to rotate, and the transmission rotating rod drives the cleaning wiping plate and the cleaning scraping plate to rotate, cleaning the inner wall and bottom of the drainage cylinder bottle body. The cleaning process is convenient and has a good cleaning effect on viscous liquids such as effusion and blood. A sliding collection box is provided to collect the small amount of liquid scraped at the bottom, avoiding the situation of incomplete dumping. Description of the Drawings

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] Please refer to Figures 1 - 5 , the present invention provides a technical solution for a drainage device:
[0025] Embodiment 1:
[0026] According to Figure 1 , Figure 2 and Figure 4As shown in the figure, a drainage device includes an auxiliary cylinder 1. At the bottom of one side wall of the auxiliary cylinder 1, a first-stage drainage pipe 2 is installed. One end of the first-stage drainage pipe 2 is equipped with a first one-way valve 4, which ensures the one-way flow of internal accumulated liquid and can only enter the inside of the auxiliary cylinder 1 and cannot flow back from the auxiliary cylinder 1 into the first-stage drainage pipe 2. At the bottom of the other side wall of the auxiliary cylinder 1, a last-stage drainage pipe 501 is installed. One end of the last-stage drainage pipe 501 is snap-connected to a drainage cylinder 5, and the top of the drainage cylinder 5 is snap-connected to a cylinder cover 502. A sealing push rod 7 is vertically slidably connected to the inner wall of the auxiliary cylinder 1. A limiting collar 701 is provided at the top of the auxiliary cylinder 1. The top end of the sealing push rod 7 is fixedly connected to a sliding plug 705. The top end of the sliding plug 705 is rotatably connected to an arm 704. A limiting vertical plate 6 is provided on one side of the limiting collar 701. The top end of the limiting vertical plate 6 is fixedly connected to a motor 601. The output end of the motor 601 is fixedly connected to a transmission rotating plate 702. A fixed short column 703 is fixedly connected to the side wall of the transmission rotating plate 702. Fixed support plates 602 are fixedly connected to one side wall of the limiting collar 701 and the top of one side wall of the auxiliary cylinder 1 respectively. The limiting vertical plate 6 passes through the two fixed support plates 602. Adhesive layers are provided at one ends of the two fixed support plates 602. With the help of the adhesive layers, the auxiliary cylinder 1 can be pasted at an appropriate height, such as on the side wall of a hospital bed, between the first-stage drainage pipe 2 and the last-stage drainage pipe 501, without affecting its normal drainage. When the gravity is insufficient, it can assist in boosting the pressure. A second one-way valve 3 is installed in the middle of the last-stage drainage pipe 501, which ensures the one-way flow of internal accumulated liquid. The sliding plug 705 is slidably connected to the inner wall of the limiting collar 701, and the top of the arm 704 is rotatably connected to the fixed short column 703.
[0027] In specific use, for a drainage device of the present utility model, when it is necessary to drain the effusion or secretion in the patient's chest cavity, one end of the first-stage drainage tube 2 away from the auxiliary cylinder 1 can be placed at the chest drainage site of the patient. Subsequently, the drainage cylinder 5 is placed on the ground under the bed or other places to form a height difference, and drainage can be carried out by means of the liquid gravity of the height difference. Among them, the auxiliary cylinder 1 is pasted on the side wall of the bed body by means of the adhesive layer on the two fixed support plates 602. When the drainage tube inevitably bends and coils, is pressed under the body or is wound, etc., the motor 601 can be started at this time. The output end of the motor 601 drives the transmission rotating plate 702 and the fixed short column 703 to rotate, so that one end of the support arm 704 rotates with the fixed short column 703. The rotation of the support arm 704 causes the other end of the support arm 704 to drive the sliding plug 705 to slide up and down on the inner wall of the limit collar 701. When the sealing push rod 7 slides upward, a negative pressure can be generated inside the first-stage drainage tube 2 to increase the extraction force, and the blocked or stagnant effusion due to insufficient gravity can be drained out. When the sealing push rod 7 slides downward, the effusion drawn into the auxiliary cylinder 1 can be pushed into the end-stage drainage tube 501 and then sent into the drainage cylinder 5, thus completing the effusion drainage and collection process. In this way, it can be used as an auxiliary drainage when the gravity is insufficient or the liquid flow power is insufficient. When the height difference of the drainage is appropriate and there is appropriate gravity drainage, the motor 601 can be turned off for normal drainage to avoid excessive extraction.
[0028] Embodiment 2:
[0029] On the basis of Embodiment 1, such as Figure 1 、 Figure 3 and Figure 4 、 Figure 5As shown in the figure, a gear 503 is rotatably connected to the center of the cylinder cover 502. A rack 504 is meshed and connected to one side of the gear 503. A transmission rotating rod 901 is provided at the bottom of the cylinder cover 502. The top end of the transmission rotating rod 901 is threadedly connected to the bottom end of the gear 503. A plurality of extended fixing plates 9 are fixedly connected to the side wall of the transmission rotating rod 901. A cleaning wiping plate 902 is snap-fitted to one side of each extended fixing plate 9. A cleaning scraping plate 903 is attached to the bottom of one side of each of the plurality of cleaning wiping plates 902. A scale plate 11 is fixedly connected to one side wall of the drainage cylinder 5. A first magnetic attraction 10 is provided on one side of the scale plate 11. The back surface of the first magnetic attraction 10 is slidably connected to the side wall of the drainage cylinder 5. A second magnetic attraction 12 is slidably connected to the inner wall of the drainage cylinder 5. The second magnetic attraction 12 is magnetically attracted to the first magnetic attraction 10. The drainage cylinder 5 is made of a transparent material and a magnetically conductive material. The movement of the second magnetic attraction 12 inside can drive the movement of the external first magnetic attraction 10. In this way, the cooperation between the external first magnetic attraction 10 and the scale plate 11 makes the numerical observation clearer. Note that this structure needs to be disassembled and taken out during the cleaning stage. A floating buoy 13 is fixedly connected to one side wall of the second magnetic attraction 12. The floating buoy 13 has a large volume and a light mass, and will obtain a large buoyancy in liquids such as accumulated fluid or blood. One end of each of the plurality of cleaning scraping plates 903 is snap-fitted to the side wall of the transmission rotating rod 901. A sliding collection box 8 is snap-fitted to the bottom end of the drainage cylinder 5. A buckle groove is opened at the bottom end of the sliding collection box 8, and the buckle groove can be disassembled and opened by means of tools. The plurality of cleaning wiping plates 902 and the plurality of cleaning scraping plates 903 are respectively attached to the inner wall of the drainage cylinder 5 and the inner wall of the bottom end of the drainage cylinder 5.
[0030] During specific use, for a drainage device of the present utility model, when accumulated fluid or secretions enter the drainage cylinder 5, as the accumulated fluid continuously enters, the liquid level inside the drainage cylinder 5 gradually rises. The rising liquid level drives the floating buoy 13 to rise, and the floating buoy 13 drives the second magnetic attraction 12 to rise, so that the second magnetic attraction 12 drives the first magnetic attraction 10 to rise. It is convenient for the patient to judge the liquid level of the accumulated fluid inside the drainage cylinder 5 by observing the first magnetic attraction 10. In this way, the patient can accurately master the drainage condition and avoid the situation of not knowing whether the drainage speed is too fast or too slow. When it is necessary to clean the drainage cylinder 5, first pour out the accumulated fluid inside the drainage cylinder 5, take out the floating buoy 13 and the second magnetic attraction 12, threadedly connect the transmission rotating rod 901 to the bottom of the gear 503, spray disinfectant on the inner wall of the drainage cylinder 5, snap-fit the cylinder cover 502 to the drainage cylinder 5, and then reciprocally pull the pull ring 505. The pull ring 505 drives the rack 504 to make the gear 503 rotate reciprocally, so that the cleaning wiping plate 902 and the cleaning scraping plate 903 clean the inner wall of the drainage cylinder 5. The cleaning scraping plate 903 can scrape the residual accumulated fluid on the inner bottom wall of the drainage cylinder 5 into the sliding collection box 8. Disassemble the sliding collection box 8, and the residual liquid inside the drainage cylinder 5 can be completely poured out.
