In the description of the present technology, it should also be noted that, unless otherwise expressly specified and limited, the terms "arrangement", "installation", "connection" and "connection" should be understood in a broad sense, for example, it may be a fixed connection, It can also be a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or the internal communication between the two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present technology can be understood in specific situations.

Referring to FIG. 1, the existing chest cavity closed drainage bottle is a bottle body 1 with a first cavity 100 and a bottle cap 3 arranged on the bottle body 1. The bottle cap 3 is generally provided with two openings, one for The ventilation port 31 for balancing the air pressure of the first cavity 100 and a drainage port 32 for connecting with the drainage tube. In the sterile physiological saline in the cavity 100, the mixed liquid is called drainage fluid.

The existing thoracic cavity closed drainage bottle water exchange method still adopts the operation steps of unscrewing the bottle cap 3, pouring the drainage liquid, cleaning the first cavity 100 as required, pouring in sterile physiological saline, and tightening the bottle cap 3, so that The operation method of the bottle will not only stain the bottle mouth with bacteria, increasing the probability of infection of the patient, but also because of the inconvenience of dumping, it will contaminate the skin of medical staff and even splash into the eyes.

Therefore, an improved solution on the bottle body 1 is proposed in this solution, so as to avoid repeated opening of the bottle cap 3 .

Specifically, referring to FIG. 1 , an auxiliary body 2 is provided on the side of the bottle body 1 , and the auxiliary body 2 is a cavity structure, that is, a second cavity 200 is provided in the auxiliary body 2 , and the bottle body 1 is provided with a second cavity 200 . opening 11 , so that the first cavity 100 communicates with the second cavity 200 through the opening 11 .

Preferably, the auxiliary body 2 is composed of a conical and transparent plastic box or a transparent plastic bag.

The second cavity 200 formed by the plastic box has a fixed shape, namely a cone shape; while the plastic bag has no fixed shape, so the second cavity 200 has no fixed shape, and only when the drainage liquid is poured into the plastic bag When the second cavity 200 is formed.

Here, the auxiliary body is preferably a plastic bag, see Figure 2, because the plastic bag itself has a certain toughness, when no drainage fluid is injected, the plastic bag tightly fits the bottle body, and the whole device does not appear bloated; After draining the fluid, the flexibility of the plastic bag makes it possible to hold a larger volume of drain fluid.

The specific operation steps are:

Referring to FIG. 1 , when the drainage liquid in the first cavity 100 needs to be poured and replaced, tilt the bottle body 1 so that the drainage liquid in the first cavity 100 flows to the second cavity 200 along the opening 11 , thereby completing the drainage pouring of liquid.

Of course, the first chamber 100 should also be cleaned before re-injecting the sterile physiological saline into the first chamber 100. In order to avoid the need to open the bottle cap 3 to fill in the cleaning liquid, here the cleaning liquid is passed through the vent 31. Filled into the first cavity 100 .

Since the diameter of the nozzle of the vent 31 is small, the cleaning liquid cannot be easily filled. Therefore, a funnel 33 for diversion is movably inserted into the vent 31, and the funnel 33 can be easily inserted into the first cavity 100 through the funnel 33. Fill with cleaning liquid.

Preferably, in order to avoid contamination of the funnel 33 and to avoid repeated use, the funnel 33 is a disposable sterile product.

After cleaning the first cavity 100 with the cleaning liquid, it is also poured into the second cavity 200 in the same way as the drainage liquid.

The drainage liquid or cleaning liquid in the second chamber 200 needs to be removed in time. Therefore, an external discharge device 4 is provided at the bottom of the second chamber 200, and the external discharge device 4 can be used to easily remove the drainage liquid or the cleaning liquid. Cleaning liquid drains.

Specifically, the external drainage device 4 is an improved drainage pipe.

Referring to FIG. 3 , the end of the drain pipe that communicates with the second chamber 200 is defined as the connection end 41 , the end away from the second chamber 200 is the free end 43 , and the position between the connection end 41 and the free end 43 is defined as the middle end 42. The middle end 42 is provided with a stop plug 5 which can make the drainage fluid flow out or stop the flow out.

That is to say, the specific usage method is as follows: before the liquid needs to be poured from the first chamber 100 to the second chamber 200, the stop plug 5 is inserted into the middle end 42 of the drain pipe, so that the connection end 41 of the drain pipe is connected to the free end 43. After all the liquid is poured into the second chamber 200, the stop plug 5 is pulled out, so that the connecting end 41 and the channel of the free end 43 are connected, and the liquid in the second chamber 200 passes through The free end 43 leads into a dedicated waste pond (not shown) for collecting drainage.

Of course, a reasonable structure is also made for the cooperation between the flow stop plug 5 and the drain pipe.

Referring to FIGS. 3-4 , the specific structure is that the middle end 42 of the drain pipe is provided with a plug pipe 6 specially used for the insertion of the stop plug 5, the two ends of the plug pipe 6 are connected, and the plug pipe 6 is similar to the drainage pipe. In the structure of the four-way pipe, the stop plug 5 is inserted into the plug pipe 6 .

In order to ensure the tightness, the flow stop plug 5 and the plug tube 6 are in an interference fit.

Here, further improvements are made to the stop plug 5 to achieve the effect of connecting or blocking the passage between the connection end 41 and the free end 43 without completely pulling out the entire stop plug 5 .

Specifically, the stop plug 5 includes a plug body 51 with an axial direction. One end of the plug body 51 is provided with a boss 52 abutting against the plug tube 6 , and the other end is provided with a turning head 53 that is convenient for the user to rotate. ; The middle position of the plug body 51 is provided with a through hole 54 that runs through and is perpendicular to the axial direction.

Preferably, the flow stop plug 5 is an integrally formed structure.

Referring to FIG. 5 , insert the stop plug 5 into the plug tube 6 so that the boss 52 abuts on one end of the plug tube 6 , the rotor 53 protrudes from the other end of the plug tube 6 , and the medical staff rotates the rotor 53 by hand , the entire stop pin 5 can be rotated, and the through hole 54 can be connected or dislocated with the channel in the drain pipe, so that the effect of channel communication or blocking can be achieved. Connected state.

Of course, there is another structural method here, referring to FIG. 6 , that is, the through hole 54 is arranged at one end close to the turning head 53. When the drain pipe channel needs to be connected, push the turning head 53 with your fingers to make the boss 52 protrude from the latch. The pipe 6 is not in contact with it, and the through hole 54 is communicated with the drainage pipe channel at this time; the dotted line in FIG. 6 is the state when the through hole 54 is communicated with the drainage pipe after pushing out the boss 52; when it is necessary to block the drainage pipe channel, use Fingers push the boss 52 to make the boss 52 abut against the plug tube 6 , and the rotor 53 protrudes out of the plug tube at this time, so that the through hole 54 and the drainage pipe channel are dislocated.

Preferably, the drainage pipe is a drainage pipe made of soft material or a corrugated pipe with folding and telescopic properties.

Considering that the free end 43 of the drain pipe cannot be exposed all the time, it should be stored after the drainage is completed. The bottle body 1 or the auxiliary body 2 is provided with a free end of the drain pipe. For the container cap 7, see Figure 3, Figure 5-Figure 6.

After use, the free end 43 of the drain pipe is inserted into the container cap 7, so as to avoid being placed in the air for a long time and avoid being polluted.

Preferably, the height of the container cap 7 should be higher than the overall height of the drain pipe. After the free end 43 of the drain pipe is bent upwards and inserted into the container cap 7, it can effectively prevent the drainage droplets remaining in the drain pipe from leaking.

The above scheme utilizes the second cavity 200 to achieve the purpose of replacing the liquid in the first cavity 100. Of course, the use of the second cavity 200 has another advantage, that is, the color contrast of the drainage fluid, medical staff and patients can clearly observation of the condition.

That is, after the patient uses the chest cavity closed drainage bottle, the first cavity 100 is filled with turbid drainage fluid. A new sterile physiological saline is injected into the cavity 100, and after a period of use, the drainage fluid located in the first cavity 100 and the drainage fluid located in the second cavity 200 can be compared, and the condition can be seen very intuitively. changes.

As a variant of the proposed solution, the design of the second chamber 200 may not be adopted, that is, the outer discharge device 4 is directly disposed at the bottom position of the bottle body 1, and the outer discharge device 4 has the same structure as mentioned above. .

Here, the container cap 7 can only be set on the bottle body 1. Referring to FIG. 7, the free end 43 of the drain pipe can be inserted into the container cap 7 after being bent upward.
