Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a wound drainage device. Background Art
[0002] The wound drainage device is used to transfer (draw out) the exudate at the wound in time. The wound drainage device in the prior art usually includes a patch for applying to the wound and a drainage interface formed on the patch. A drainage tube is connected to the drainage port, and the exudate actively passes through the drainage interface and flows out through the drainage tube, or the exudate is drawn out by the suction action of a suction device (such as a syringe) on the drainage tube.
[0003] However, the above-mentioned wound drainage device in the prior art has the following defects:
[0004] The drainage tube is always attached to the drainage interface of the patch. Moreover, in order to avoid polluting the environment after the exudate flows out, a container (such as a spherical sac) for temporarily storing the exudate needs to be attached to the end of the drainage tube, which results in an insufficiently compact structure of the wound drainage device. Summary of the Utility Model

[0029] In order to keep the following description of the embodiments of this utility model clear and concise, the detailed descriptions of known functions and known components are omitted in this utility model.
[0030] As Figure 1 As shown, the embodiments of this utility model disclose a wound drainage device, which includes: a patch 10, a cover 20, a first rubber plug 61, a second rubber plug 62, a check valve 40 and a liquid suction component 50.
[0031] The patch 10 is used to be attached to the wound, and the edge of the patch 10 is bonded to and substantially seals the skin around the wound. A first outlet 11 is formed in the middle of the patch 10.
[0032] The cover 20 is buckled on the patch 10. Specifically, the cover 20 is buckled on the patch 10 by a screwing method. Thus, the cover 20 can be removed from the patch 10 by unscrewing. After the cover 20 is buckled on the patch 10, the cover 20 and the patch 10 enclose a temporary storage cavity 30. A second outlet 21 is formed at the center of the top of the cover 20.
[0033] The first rubber plug 61 is arranged at the second outlet 21. The first rubber plug 61 has an openable and closable gap. Thus, as Figure 2As shown, the suction pipe can extend into the temporary storage cavity 30 through the first rubber plug 61. And after the suction pipe is withdrawn from the first rubber plug 61 and the gap of the first rubber plug 61 is closed, the first rubber plug 61 makes the temporary storage cavity 30 basically in a sealed state.
[0034] The check valve 40 is arranged at the first outlet 11. The check valve 40 includes a valve frame 41 and a silica gel sheet 42; the valve frame 41 has a conical table surface 411 protruding into the temporary storage cavity 30. A plurality of hollow parts 412 are arranged on the conical table surface 411. The plurality of hollow parts 412 are arranged circumferentially. The silica gel sheet 42 covers the conical table surface 411, so as to be able to cover and close the hollow parts 412. The lower part of the outer side of the silica gel sheet 42 is adhesively fixed to the conical table surface 411, and the upper part of the inner side of the silica gel sheet 42 remains in a free state. In this way, the silica gel sheet 42 can open the hollow parts 412 by radially deforming outwards, and the silica gel sheet 42 closes the hollow parts 412 by elastic reset.
[0035] The top of the valve frame 41 is provided with a socket 413. The second rubber plug 62 is arranged at the socket 413. The second rubber plug 62 has an openable and closable gap. Thus, as Figure 3 shown, the liquid supply pipe can extend through the second rubber plug 62 to the vicinity of the wound under the patch 10.
[0036] A liquid absorption component 50 such as a sponge is arranged in the temporary storage cavity 30. The liquid absorption component 50 is used to absorb the liquid in the temporary storage cavity 30, such as exudate.
[0037] The following introduces the usage method of the above-mentioned wound drainage device.
[0038] The wound drainage device is arranged at the wound in the state as Figure 1 shown. When exudate oozes from the wound, the suction pipe is passed through the first rubber plug 61 and extends into the temporary storage cavity 30. The temporary storage cavity 30 is sucked into a negative pressure state by using the suction pipe. Thus, as Figure 2 shown, the silica gel sheet 42 of the check valve 40 opens the hollow parts 412, and the exudate at the wound enters the temporary storage cavity 30 through the check valve 40. The temporary storage cavity 30 is kept in a negative pressure state, which can make the exudate oozing from the wound continuously enter the temporary storage cavity 30.
[0039] The exudate entering the temporary storage cavity 30 is adsorbed by the liquid absorption component 50. Subsequently, the exudate in the temporary storage cavity 30 can be removed by the suction of the suction pipe, or the liquid absorption component 50 can be taken out of the temporary storage cavity 30 to remove the exudate.
[0040] As Figure 3 shown, by passing the liquid supply pipe through the first rubber plug 61 and the second rubber plug 62 in sequence, the liquid supply pipe extends to the vicinity of the wound, so as to supply liquid to the wound and avoid opening the patch 10 for drug administration.
[0041] In addition, although exemplary embodiments have been described in the present utility model, the scope thereof includes any and all embodiments based on the present utility model having equivalent elements, modifications, omissions, combinations (e.g., solutions that cross various embodiments), adaptations or changes. The elements in the claims will be broadly interpreted based on the language employed in the claims and are not limited to the examples described in this specification or during the implementation of this application, and the examples will be construed as non-exclusive. Therefore, this specification and the examples are intended to be considered only as examples, and the true scope and spirit are indicated by the following claims and the full scope of their equivalents.
[0042] The above description is intended to be illustrative rather than restrictive. For example, the above examples (or one or more of their solutions) can be used in combination with each other. For example, those of ordinary skill in the art can use other embodiments when reading the above description. Additionally, in the above detailed description, various features can be grouped together to simplify the present utility model. This should not be construed as an intention that a disclosed feature not claimed is necessary for any claim. On the contrary, the subject matter of the present utility model can be less than all the features of a particular disclosed embodiment.
