[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0028] Refer to Figures 1-5 As shown, a colorimetric device for closed thoracic drainage includes a drainage bottle 10 and a housing 12 provided on the outer arc wall of the drainage bottle 10. A rotating assembly 30 and four pressing assemblies 20 are provided inside the housing 12. A placement groove is provided inside the housing 12. The four pressing assemblies 20 are located in the placement groove. Among them, the rotating assembly 30 is located between the pressing assembly 20 and the drainage bottle 10. The pressing assembly 20 includes a button 21 slidably connected to a side wall of the housing 12 away from the drainage bottle 10. A movable rod 22 is fixedly connected to a side wall of the button 21 close to the drainage bottle 10. A first support plate is fixedly connected to a side wall of the movable rod 22 close to the drainage bottle 10. A second support plate is fixedly connected to the front inner side wall of the placement groove corresponding to the position of the first support plate. A slide rail spring 23 is installed between the first support plate and the second support plate. A fixing ring 24 is fixedly connected to the left end of the outer arc wall of the movable rod 22. A rotating rod 25 is rotatably connected to the top of the fixing ring 24. One end of the rotating rod 25 away from the fixing ring 24 is rotatably connected to a first slider. The first slider is slidably connected to the front inner side wall of the placement groove. A first limiting block 26 is fixedly connected to the top of the first slider. The first limiting block 26 faces the slide rail spring 23. A first fixing plate 28 is provided on the right side of the first limiting block 26. A compression spring telescopic rod 27 is fixedly connected to the bottom of the first fixing plate 28. The bottom of the compression spring telescopic rod 27 is fixedly connected to the bottom inner side wall of the placement groove. The top of the first fixing plate 28 penetrates through the housing 12. The rotating assembly 30 includes a second fixing plate 34 located in front of the pressing assembly 20. The second fixing plate 34 is adapted to the first fixing plate 28. The indicating cards provided on the second fixing plate 34 correspond one by one to the photos of the drainage fluid properties on the four first fixing plates 28.
[0029] Refer to Figures 1-5As shown, a colorimetric device for closed thoracic drainage, at the bottom of one side wall of the first fixing plate 28 close to the first limiting block 26, there is a third limiting block. When the top of the first fixing plate 28 is flush with the top of the housing 12, the first limiting block 26 is located above the third limiting block and the side walls of the two close to each other are in contact. The top of the side wall of the first limiting block 26 close to the first fixing plate 28 is arc-shaped, and the bottom of the side wall of the third limiting block close to the first slider is arc-shaped. The arc shape enables the first fixing plate 28 not to be blocked when being pressed down, and at the same time pushes away the first limiting block 26. Once the two arc surfaces are no longer in contact, the first limiting block 26 will reset under the action of the slide rail spring 23.
[0030] Refer to Figures 1-5 As shown, a colorimetric device for closed thoracic drainage, on the top of the first support plate and the second support plate on the front side wall of the movable rod 22, there are columns and they are located on the same side. The slide rail spring 23 is V-shaped. One end of the slide rail spring 23 is rotatably connected to the outer arc wall of the column on the top of the first support plate, and the other end of the slide rail spring 23 is rotatably connected to the outer arc wall of the column on the top of the second support plate. The middle part of the slide rail spring 23 is located on the side of the two columns away from the first limiting block 26. When pressing the button 21, the slide rail spring 23 moves forward. When the middle part of the slide rail spring 23 abuts against the front inner side wall of the placement groove, the first support plate and the second support plate are in contact, and at this time, the button 21 cannot be pressed continuously.
[0031] Refer to Figures 1-5 As shown, a colorimetric device for closed thoracic drainage, at one end of the top of the housing 12 close to the drainage bottle 10, there is a vertically penetrating sliding channel. The rotating assembly 30 is located in the sliding channel. The sliding channel is located between the placement groove and the drainage bottle 10, and the sliding channel is not communicated with the placement groove.
[0032] Refer to Figures 1-5 As shown, a colorimetric device for closed thoracic drainage, the rotating assembly 30 includes a damping rotating shaft 33. Two ends of the damping rotating shaft 33 are respectively fixedly connected with gears 32. On one side of the two gears 32 close to the pressing assembly 20, there is a same second fixing plate 34 engaged. The second fixing plate 34 is slidably connected in the sliding channel. One end of the damping rotating shaft 33 is fixedly connected with a knob 31. The knob 31 is located outside the housing 12. Two ends of the damping rotating shaft 33 are respectively rotatably connected to the left and right inner side walls of the sliding channel. The second fixing plate 34 is provided with racks at positions corresponding to the two gears 32.
[0033] Refer to Figures 1-5As shown in the figure, there is a colorimetric device for closed thoracic drainage. An indicating card is provided on one side wall of the second fixing plate 34 close to the pressing component 20. The indicating card is divided into four intervals according to the common colors of the drainage fluid. The first fixing plates 28 in the four pressing components 20 are respectively provided with photos of the drainage fluid in different shapes. The four intervals correspond to the four first fixing plates 28 one by one. The lengths of the top opening and the bottom opening of the sliding channel are both smaller than the length inside the sliding channel. It should be noted here that the four color intervals set in this device are only the color conditions of the four common drainage fluids during the operation, and do not represent all possible color conditions of the drainage fluid.
[0034] Refer to Figures 1-5 As shown in the figure, there is a colorimetric device for closed thoracic drainage. Vertical dovetail grooves are provided on the left and right side walls of the second fixing plate 34. Two limiting blocks 35 are slidably connected in the two dovetail grooves. One ends of the two limiting blocks 35 away from the second fixing plate 34 respectively abut against the left and right inner side walls of the sliding channel. When the second fixing plate 34 moves upward, the limiting blocks 35 move upward synchronously. When the top of the limiting block 35 abuts against the top opening of the sliding channel, the second fixing plate 34 cannot continue to move upward.
[0035] Refer to Figures 1-5 As shown in the figure, there is a colorimetric device for closed thoracic drainage. One side wall of the housing 12 close to the drainage bottle 10 is arc-shaped. Scale lines are provided on the outer arc wall of the drainage bottle 10. The elastic fixing band 11 is made of a transparent material, and the elastic fixing band 11 being made of a transparent material facilitates observing the scale lines on the body of the drainage bottle 10.
[0036] Working principle:
[0037] Step 1: In the initial state, the top of the first fixing plate 28 is flush with the top of the housing 12. The second fixing plate 34 is located inside the sliding channel. During the closed thoracic drainage operation, the doctor inserts one end of the drainage tube into the patient's body, and the other end is connected to the drainage bottle 10 and the horizontal height of the drainage bottle 10 should be lower than the height of the patient's intubation position. Subsequently, the elastic fixing band 11 is sleeved on the drainage bottle 10.
[0038] Step 2: When the medical staff needs to check the color and properties of the drainage fluid, first rotate the knob 31 according to the horizontal height of the drainage fluid in the drainage bottle 10. When the drainage fluid is less, the knob 31 can be rotated clockwise. The knob 31 drives the damping rotating shaft 33 to rotate, and the damping rotating shaft 33 drives the two gears 32 to rotate. The two gears 32 drive the second fixing plate 34 to descend and expose from the sliding channel. When the knob 31 rotates a certain number of turns, the top end of the second fixing plate 34 is located at the bottom end of the sliding channel. The limiting block 35 slides in the first chute. When the limiting block 35 abuts against the top inner side wall of the first chute, the knob 31 cannot continue to rotate clockwise. At this time, the exposed part of the second fixing plate 34 is sufficient for the medical staff to perform color comparison.
[0039] Step 3: When there is a large amount of drainage fluid, the knob 31 can be rotated counterclockwise, and the rotating assembly 30 will drive the fixing plate two 34 to move upward. Medical staff can judge the specific color of the drainage fluid according to the instruction card, and then press the button 21 corresponding to the color range where the drainage fluid is located. After the button 21 is pressed, it drives the movable rod 22 to move forward. The movable rod 22 drives the slide rail spring 23 and the fixing ring 24 to move forward. The fixing ring 24 simultaneously causes the rotating rod 25 to move leftward to drive the first slider to slide. The first slider drives the first limiting block 26 to slide. Subsequently, the second limiting block 35 is no longer restricted by the first limiting block 26, so that the fixing plate one 28 pops upward under the action of the compression spring telescopic rod 27. The fixing plate one 28 is exposed from the top of the housing 12, which is convenient for medical staff to further confirm the color and properties of the drainage fluid with reference to the photo on the fixing plate one 28.
[0040] Step 4: When the button 21 is pressed, the first support plate at the front end of the movable rod 22 abuts against the second support plate in the placement groove. Subsequently, under the action of the slide rail spring 23, when the user no longer presses the button 21, it can be reset. After the inspection is completed, manually press the fixing plate one 28 to reset it. When the second limiting block 35 abuts against the first limiting block 26, the arc surfaces of the two cause the first limiting block 26 to slide adaptively. When the arc surfaces of the second limiting block 35 and the first limiting block 26 are no longer in contact, the first limiting block 26 immediately resets to limit the second limiting block 35, and then rotate the knob 31 to reset the rotating assembly 30.
