Description

Technical Field

[0001] This invention relates to the field of wound tissue closure and negative pressure drainage, specifically to a septic tank with a quick-connect interface for switching septic containers. Background Technology

[0002] The recently emerging vacuum-sealing drainage (VSD) technique has been clinically validated for covering and draining acute and chronic wounds and ulcers, as well as large soft tissue defects. Its application in traumatic osteomyelitis has naturally become a treatment method for clinicians. Currently, the VSD wound covering materials on the market are mainly biosynthetic materials such as foam or sponge. During application, these materials cannot remove viscous exudate and necrotic sloughed tissue. The most common problem is drainage tube blockage, leading to increased bacterial count, significant odor, and hindering wound healing.

[0003] Effective wound irrigation combined with negative pressure therapy can help remove wound exudate, necrotic tissue, bacteria, and toxins from the wound bed, promoting wound healing.

[0004] When some wounds require a large amount of irrigation, with a 24-hour irrigation volume reaching 3000ml, the maximum capacity of a conventional effusion tank is only about 2000ml. Two effusion tanks need to be replaced every day, which increases the financial burden on patients compared to the cost of the effusion tanks. In addition, when patients need to get out of bed, carrying a large-capacity effusion tank and machine filled with a large amount of irrigation fluid is very inconvenient due to its overall weight. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems existing in the prior art and provide a liquid collection tank with a quick-connect interface for switching liquid collection containers, so as to quickly transfer the flushing fluid to a replaceable, inexpensive, disposable liquid collection container, thereby reducing the volume of the liquid collection tank and making it convenient to carry.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution:

[0007] A fluid collection container with a quick-connect interface and a switchable fluid collection container includes a fluid collection container body and a closed fluid collection container cavity. The upper part of the inner side wall of the fluid collection container body is provided with a suction hole communicating with the fluid collection container cavity. The upper part of the outer side wall of the fluid collection container body is provided with a pair of quick-connect interfaces for connecting an external fluid collection container. One quick-connect interface communicates with the fluid collection container cavity, so that a negative pressure environment is formed inside the fluid collection container. The other quick-connect interface bridges and communicates with the suction hole, so that the fluid collection container can directly draw irrigation fluid from the wound dressing.

[0008] Furthermore, the quick-connect interface consists of a liquid collection tank inlet and a quick-connect tube. The liquid collection tank inlet is located on the outer wall of the liquid collection tank and is connected to the liquid collection tank cavity. One end of the quick-connect tube is connected to the liquid collection container through a corresponding pipeline, and the other end is inserted into the liquid collection tank inlet for insertion into the liquid collection tank cavity of the liquid collection tank.

[0009] Furthermore, one of the liquid collection tank ports is directly opposite the suction hole, so that the liquid collection container passes through the liquid collection tank port through the quick-connect tube and is connected to the suction hole to form a drainage path for the liquid collection container. The liquid collection container is connected to the liquid collection tank cavity through the other liquid collection tank port and the quick-connect tube to form a suction negative pressure path for the liquid collection container.

[0010] Furthermore, the quick-connect tube has a tube buckle on its outer wall, and the liquid collection tank inlet has a protruding outer edge with a tank opening female buckle formed on its outer edge. The tube buckle and the tank opening female buckle engage with each other, so that the quick-connect tube is fixed together with the liquid collection tank inlet after being inserted.

[0011] Furthermore, the inlet of the liquid collection tank is provided with a type-1 open silicone cap, and the type-1 open silicone cap has a dome-shaped structure with the top of the dome facing the outside of the liquid collection tank. A "I"-shaped cut is made at the top of the dome, and the length of the cut is less than the diameter of the quick-connect tube, which is used to seal the inserted quick-connect tube.

[0012] Furthermore, an O-ring silicone cap is provided on the end of the suction hole that is directly opposite the inlet of the liquid collection tank, and the opening of the O-ring silicone cap faces the suction hole to seal the inserted quick-connect tube.

[0013] The beneficial effects of this invention are:

[0014] The quick-switch drainage sump and its matching connector of the present invention are suitable for wound treatment requiring a large amount of irrigation fluid.

[0015] This invention allows for the rapid transfer of irrigation fluid between the effusion bag and the effusion tank when the patient is out of bed or being transported. The operation is simple and reliable.

[0016] The quick-switching drainage collection tank and its matching connector of the present invention are sealed after connection, eliminating the risk of external leakage.

[0017] The snap-fit ​​structure of this invention is not easy to loosen, thus avoiding accidental pulling that could cause the quick-connect interface to separate. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1 and Figure 2 As shown, a fluid collection tank with a quick-connect interface and switchable fluid collection container includes a fluid collection tank body 7 and a closed fluid collection tank cavity. The upper part of the inner side wall of the fluid collection tank body 7 is provided with a suction hole 71 that communicates with the fluid collection tank cavity. The upper part of the outer side wall of the fluid collection tank body 7 is provided with a pair of quick-connect interfaces for connecting a fluid collection container 8. One quick-connect interface communicates with the fluid collection tank cavity, so that a negative pressure environment is formed inside the fluid collection container 8. The other quick-connect interface bridges and communicates with the suction hole 71. In this embodiment, a transition adapter is provided at the suction hole 71, so that the inner side of the transition adapter is directly connected to the quick-connect interface, and the outer side of the transition adapter is connected to the corresponding wound dressing through a suction tube, so that the fluid collection container 8 directly draws the irrigation fluid from the wound dressing.

[0029] The quick-connect interface consists of a liquid collection tank inlet 1 and a quick-connect tube 2. The liquid collection tank inlet 1 is located on the outer wall of the liquid collection tank 7 and communicates with the liquid collection tank cavity. Figure 2 As shown, one end of the quick-connect tube 2 is connected to the liquid collection container 8 through a corresponding pipeline, and the other end is inserted into the liquid collection tank inlet 1 for insertion into the liquid collection tank cavity of the liquid collection tank body 7.

[0030] like Figure 5 As shown, one of the liquid collection tank inlets 1 is directly opposite the suction hole 71, so that the liquid collection container 8 passes through the liquid collection tank inlet 1 via the quick-connect tube 2 and is connected to the suction hole 71. Figure 2 As shown, a drainage path is formed for the liquid collection container 8. The liquid collection container 8 is connected to the liquid collection tank cavity through another liquid collection tank inlet 1 and quick-connect tube 2, forming a suction negative pressure passage for the liquid collection container 8.

[0031] like Figure 3 As shown, the quick-connect tube 2 has a tube clip 3 on its outer wall, such as... Figure 4 As shown, the liquid collection tank inlet 1 has a protruding outer edge and a can opening female buckle 4 is formed on its outer edge. The insertion tube buckle 3 is engaged with the can opening female buckle 4, so that the quick-connect insertion tube 2 is fixed together with the liquid collection tank inlet 1 after being inserted.

[0032] like Figure 2 , Figure 5 and Figure 6 As shown, an O-ring silicone cap 5 is provided on the end of the suction hole 71 that is directly opposite the inlet 1 of the collection tank, and the opening of the O-ring silicone cap 5 faces the suction hole 71. It is used to seal the inserted quick-connect tube 2. The O-ring silicone cap 5 is made of silicone material. When the quick-connect tube 2 is not inserted, the flushing fluid flows into the collection tank cavity through the suction hole 71. When the quick-connect tube 2 is inserted, the quick-connect tube 2 is connected and sealed with the O-ring silicone cap 5. The flushing fluid then flows into the quick-connect tube 2 through the suction hole 71, and finally enters the collection container 8 through the quick-connect tube 2 and the corresponding drainage pipe, thereby achieving the purpose of transferring the flushing fluid to the collection container 8.

[0033] like Figure 2 , Figure 5 and Figure 7As shown, the inlet 1 of the liquid collection tank is equipped with a type-1 open silicone cap 6, which has a dome-shaped structure. The top of the dome faces outward from the liquid collection tank body 7. A "I"-shaped cut is made at the top of the dome, the length of which is less than the diameter of the quick-connect tube 2. This cut is used to seal the inserted quick-connect tube 2. When the quick-connect tube 2 is not inserted, the external atmospheric pressure is greater than the pressure inside the liquid collection tank body 7. The top of the dome of the type-1 open silicone cap 6 is subjected to pressure from the outside inward. The pressure at the "I"-shaped cut increases, and the liquid collection tank... The greater the negative pressure inside the body 7, the greater the pressure of the "I"-shaped cut, thus achieving the function of sealing the liquid collection tank 7. When the quick-connect tube 2 is inserted into the liquid collection tank inlet 1, the "I"-shaped cut of the type-1 open silicone cap 6 is opened by force. Since the cut length is less than the diameter of the quick-connect tube 2, and the type-1 open silicone cap 6 is made of silicone material, which is elastic, it seals the quick-connect tube 2 under force, thus achieving the sealing function. When the sealing quick-connect tube 2 is removed, the "I"-shaped cut of the type-1 open silicone cap 6 returns to its original state, thus achieving the sealing function again.

[0034] Usage and Principle of the Invention

[0035] The fluid collection tank with quick-connect interface of this invention can quickly transfer drainage fluid to a replaceable, inexpensive disposable drainage bag or a reusable, large-capacity fluid collection container 8. The volume of the fluid collection tank 7 can be made very small, making it easy to carry. When performing irrigation treatment at the bedside, a large amount of irrigation fluid is transferred to the disposable drainage bag through the quick-connect interface. The drainage bag can be replaced when the fluid is full. When the patient needs to be transferred or get out of bed, the quick-connect tube 2 is removed, and the type-one open silicone cap 6 immediately restores and seals the fluid collection tank 7. The irrigation fluid flows into the fluid collection tank cavity and is removed from the bulky fluid collection tube and the fluid collection container 8. Only the lightweight and compact fluid collection tank 7 needs to be carried, realizing quick and flexible switching of irrigation fluid between the fluid collection tank 7 and the fluid collection container 8. The operation is convenient and simple, easy for patients to carry, reduces the need for fluid tube replacement, and saves resources.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
