A shell with an open end. In an optional embodiment, the body 1 can be a three-dimensional shell formed by folding a planar structure. At this time, the unfolded body 1 is folded into a specific shape outside the drainage tube body 14 (That is to say, after the body 1 is folded, a collection cavity 11 is formed inside, so that the liquid inlet end of the drainage tube body 14 and the drainage port 13 are located inside the collection cavity 11), and then one end of the folded body 1 is passed through the adhesive 12 adheres to the skin on the outside of the drainage port 13, while the other side is sealed and bonded to the drainage tube body 14, so that a closed space is formed in the collection cavity 11. Since the closed space is formed in the collection cavity 11, when the drainage fluid flows from the drainage After the mouth 13 seeps out, it will enter the confined space, and then the drainage fluid can be discharged out of the collection chamber 11 through the excretion port. Compared with the traditional operation of wrapping the drainage opening 13 with gauze, the drainage fluid seeping out of the drainage opening 13 will be absorbed by the gauze And contact with the drainage port 13, which increases the risk of infection of the drainage port 13, and timely discharge of the drainage fluid in the collection cavity 11 can greatly reduce the time of drainage fluid and the skin around the drainage port 13, and prevent the drainage port 13 from infection.

Further, during installation, manually squeeze the connection between the main body 1 and the drainage tube body 14 and fix it with an adhesive (such as tape), so that the pressure of the collection chamber 11 can be increased, and the collection chamber 11 can form an air pressure relative to the abdominal cavity difference, so that the air pressure outside the drainage port 13 is higher than the air pressure inside the drainage port 13 (that is, the air pressure in the collection chamber 11 is higher than the air pressure inside the human body), and the air pressure difference between the collection chamber 11 and the inside of the human body can effectively reduce drainage. The fluid seeps out, reducing the probability of drainage fluid seeping out from the drainage port 13, and correspondingly reducing the risk of infection around the drainage port 13.

At this time, when the air pressure inside the human body and the air pressure in the collection chamber 11 are relatively balanced, the position where the extruding disc 42 slides in the annular sticker frame 4, that is, the position where the extruding disc 42 slides in the annular the balance position of the frame 4), at this time, reversely rotate the extruded threaded rod 33, and the extruded threaded rod 33 drives the extruded circular plate 42 to slide toward the inner end of the collection chamber 11 (that is, the extruded circular plate 42 is placed in the ring-shaped frame 4 slide inward towards the end close to the skin), because the airtight space formed in the collection chamber 11 makes the air pressure in the collection chamber 11 higher than the air pressure inside the human body, the pressure difference formed between the collection chamber 11 and the inside of the human body can effectively reduce the leakage of drainage fluid , reduce the probability of drainage fluid leaking from the drainage port 13, and correspondingly reduce the risk of infection around the drainage port 13; The collection chambers 11 are connected so that the air pressure difference formed between the collection chamber 11 and the drainage port 13 gradually decreases until the air pressure difference disappears. After the air pressure difference disappears, there may still be drainage fluid leaking from the drainage port 13 at the position of the drainage port 13 (or when the above-mentioned extruded disc 42 finds a balanced position in the ring-shaped frame 4, when the drainage port 13 has drainage fluid discharged), the medical staff reversely rotates the extruded threaded rod 33 to make the extruded disc 42 flow toward the collection chamber 11 inside one end slides (that is, extrudes the circular plate 42 to slide toward the end close to the skin in the ring-shaped frame 4), pressurizes the collection chamber 11, can effectively reduce the leakage of drainage fluid, and reduce the leakage of drainage fluid from the drainage port 13. The probability of outflow correspondingly reduces the risk of infection around the drainage port 13; (5) After the drainage fluid seeps out from the drainage port 13, the drainage tube 16 transports the drainage fluid from the collection cavity 11 to the drainage bag in time, so that the collected The cavity 11 will not be kept in a wet state for a long time, reducing the contact time between the drainage fluid and the skin around the drainage port 13, effectively preventing the risk of infection at the drainage port 13, and improving the dryness of the collection cavity 11.

Preferably, the part of the discharge pipe 16 located outside the collection chamber 11 is provided with a valve 17, and the valve 17 is used to open or close the discharge pipe 16. Specifically, when it is necessary to manually squeeze the main body 1 and the drainage pipe body 14 When connecting, or reversely rotate the extruding threaded rod 33 to make it drive the extruding disc 42 to slide toward the inner end of the collection chamber 11 (that is, the extruding disc 42 slides toward the end close to the skin in the annular sticker frame 4), due to the collection When a closed space is formed in the chamber 11, so that the air pressure in the collection chamber 11 is higher than the air pressure inside the human body, or when the body 1 is adhered to the skin outside the drainage port 13 by the adhesive member 12 at the beginning, the above several In all cases, the valve 17 needs to be closed, and when drainage fluid is accumulated in the collection chamber 11 (that is, the drainage fluid seeps out from the drainage port 13 into the collection chamber 11), the switch of the valve needs to be opened (opening of the valve 17 time is relatively short), the drainage fluid is discharged from the collection cavity 11 through the negative pressure generated in the drainage bag (the other end of the drainage tube 16 is connected to the drainage bag at this time) (this is the prior art, and will not be described in detail), and the drainage fluid passes through the drainage tube 16 flows into the drainage bag, and the drainage fluid is discharged from the collection cavity 11 faster, so the opening time of the valve 17 is relatively short. The drainage fluid can be discharged from the collection cavity 11 .

Preferably, the inner side wall of the collection chamber 11 is located outside the discharge pipe 16 (that is, the part of the inner side wall of the collection chamber 11 between the discharge pipe 16 and the sealing sticker 15) is fixedly connected with a floating sheet 18, and the floating sheet 18 is A soft sheet with a density lower than water, one end of which is affixed to the inner wall of the collection chamber 11, and its entirety covers the communication opening between the discharge pipe 16 and the collection chamber 11, so that when drainage fluid is accumulated in the collection chamber 11, The floating sheet 18 floats on the surface of the drainage fluid under the buoyancy of the drainage fluid. When the valve 17 is opened, the drainage fluid is discharged from the collection chamber 11 due to the negative pressure generated in the drainage bag, and the opening time of the valve 17 is relatively short. (Because the drainage liquid is discharged from the collection chamber 11 faster, the opening time of the valve 17 is shorter) and the floating sheet 18 has a certain isolation effect on the gas in the collection chamber 11, so that the drainage liquid is first discharged from the collection chamber 11, And a small amount of gas in the collection chamber 11 is discharged from the collection chamber 11, which will not affect the air pressure in the collection chamber 11 (even if a small amount of gas is discharged from the collection chamber 11, it can also be squeezed by reverse rotation. The rod 33 makes it drive the extruding circular plate 42 to slide toward the inner end of the collection chamber 11 (that is, the extruding circular plate 42 slides toward the end close to the skin in the annular sticker frame 4). The air pressure inside the body is higher than the air pressure inside the human body), when the drainage fluid is discharged from the collection chamber 11, a small amount of drainage fluid remains on the floating sheet 18 (the drainage fluid remains on the side where the floating sheet 18 and the excretion tube 16 are connected to each other, will not flow into the skin of the human body, and will not affect the drainage port 13 and the skin nearby), and when the drainage fluid is discharged, the floating sheet 18 is attached to the side wall of the collection chamber 11 due to the negative pressure of the drainage bag In this way, the floating piece 18 can block the end of the discharge pipe 16 inside the collection chamber 11. At this time, a small amount of residual drainage fluid on the floating piece 18 has a certain liquid sealing effect on the end of the floating piece 18 blocking the inside of the collection chamber 11. So that the gas will not be discharged from the collection chamber 11 in a large amount, that is, even if the valve 17 is not closed tightly, the relative positive pressure effect of the collection chamber 11 will not be affected. After one end is blocked, the valve 17 is briefly opened to form an air pressure difference between the collection chamber 11 and the discharge pipe 16 (because the discharge pipe 16 is connected to the drainage bag, the air pressure in the discharge pipe 16 and the collection chamber 11 is unbalanced, making The air pressure in the discharge pipe 16 is lower than the air pressure in the collection chamber 11), causing the floating sheet 18 to sag to the inside of the discharge pipe 16. At this time, by observing whether the floating sheet 18 is sunken, it can be judged that the air pressure in the collection chamber 11 is in the valve 17 Whether there is a big change when it is opened (because the air pressure in the drainage bag is at a constant negative pressure, this is the prior art, so I won’t repeat it, and the air pressure in the collection chamber 11 may affect the collection chamber 11 when the valve 17 is opened. Influenced by the air pressure), if the floating sheet 18 is not sunken, it means that the collection chamber 11 is also under negative pressure. Make adjustments. Correspondingly, when the air pressure in the collection chamber 11 changes greatly, it is necessary to rotate the extrusion threaded rod 33 forward or reverse to drive the extrusion disc 42 to slide in the collection chamber 11 to ensure the air pressure in the collection chamber 11 Higher than the air pressure inside the human body, the pressure difference formed between the collection chamber 11 and the inside of the human body can effectively reduce the leakage of drainage fluid, reduce the probability of drainage fluid leakage from the drainage port 13, and correspondingly reduce the risk of infection around the drainage port 13. risk.
