Abstract
Description
Technical Field

[0002] Pleural effusion refers to the condition of excessive accumulation of fluid in the pleural cavity, which may be caused by various reasons such as infection, inflammation, and tumors. In order to relieve the patient's symptoms such as difficulty breathing and chest pain, it is usually necessary to use a pleural effusion drainage device to drain the excess fluid from the chest cavity. However, there are many problems with existing pleural effusion drainage devices. For example, the device is inconvenient to move. When transferring patients within the ward, traditional drainage devices are large in size and lack a flexible and movable structure, which makes operation difficult; the fixing method of the drainage bottle is unstable. When the patient turns over or moves, the drainage bottle is easy to shake or even overturn, affecting the drainage effect and may cause infection risks; the organization and fixation of the drainage tube is also not ideal. The drainage tube is often messy and easily tangled and bent, which hinders the smooth drainage of the fluid; because the drainage bottle is placed under the bed, it lacks the necessary warning function device and is easy to be knocked over and tipped over by the caregiver's inattention, causing medical accidents.

Its structure and composition include a water-sealed bottle negative pressure maintenance device and a drainage bottle attachment structure, which includes single-bottle, double-bottle, and triple-bottle systems. The attachment structure is often a rectangular bottle structure with a drainage tube extending from it and placed in the drainage position within the human chest cavity. Therefore, in the drawings of this device, a square block structure, as shown in the figure, is used on a placement seat to illustrate its position and the position and structure of the drainage bottle relative to the other components of the device. The inventors believe that: a person skilled in the art can clearly understand that when a medical pleural effusion drainage device of the present application is used, by searching the shapes of chest drainage bottles in the prior art and combining them with the description in the specification and the drawings, the drainage bottle is placed between several of the telescopic clamps and is clamped and fixed by adjustment; the present device can achieve stable clamping for chest drainage bottles of different specifications (such as a single-bottle system with a capacity of 500ml, a double-bottle system with a total capacity of 1000ml, etc.) by adjusting the telescopic length and of the telescopic clamp 22, thereby improving the versatility of the device.
[0014] In this embodiment, the specific use process of a medical pleural effusion drainage device is as follows: Use of mobile seat 1: When the medical pleural effusion drainage device needs to be moved, the two support rods A 12 are rotated and lowered from the bottom of the base 11 so that the universal wheels 13 touch the ground. At this time, the limit pins A 121 are inserted into the corresponding holes of the limit plate 14 to fix the position of the support rods A 12 and prevent them from shaking. The base 11 is pushed and the universal wheels 13 can be used to easily move the device to the desired position in the ward. After the movement is completed, if the device does not need to be moved, the support rods A 12 can be rotated and retracted so that the base 11 is placed directly on the ground. At this time, the limit pins B 15 can prevent the placement mechanism 2 from shaking on the base 11.
[0015] Use of placement mechanism 2: Place the drainage bottle on the placement seat 21 and adjust several telescopic clamp seats 22. Turn the threaded rod B 25 so that the threaded rod B 25 rotates relative to the placement seat 21 and the cannula A 2222, driving the two adjacent telescopic clamp seats 22 to slide back and forth linearly on the placement seat 21, thereby adjusting the size of the bottom clamp ring so that the bottom clamp ring shrinks inward and clamps around the outer bottom end of the drainage bottle. According to the height of the drainage bottle, adjust the vertical height of the telescopic clamp seat 22, and limit it with a latch, spring pin or fastening nut after adjustment. If medical supplies need to be placed in the storage box 24, open the box cover 241, put the items in, and then close the box cover 241. When the placement mechanism 2 needs to be moved as a whole, lift the lifting member 23. Since the two bottom ends of the lifting member 23 are rotatably connected to the sleeves 211 on both sides of the placement seat 21, the placement mechanism 2 can be easily lifted and moved as a whole.
[0016] Use of the clamping mechanism 3: Rotate the threaded rod A 34. The threaded rod A 34 rotates relative to the C-shaped plate 32, driving the pressing plate 33 to slide vertically within the C-shaped plate 32, and pressing the entire device firmly against the edge of the bed.
[0017] Use of the tube-winding mechanism 4: Place the drainage tube within the tube-clamping frame 42 on the tube-winding base 41. The tube-pressing pad 43 clamps and fixes the drainage tube under the action of the spring 44. Since the two tube-pressing pads 43 within two adjacent tube-clamping frames 42 are respectively located on both sides of the tube-winding base 41, it can better adapt to the placement of the drainage tube. If it is necessary to adjust the position of the tube-winding base 41, slide the tube-winding base 41 on the installation rail 45 to the required position.
