[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. Unless otherwise defined, the technical terms or scientific terms used herein should be understood as the common meanings by those skilled in the art to which the present application belongs. The similar words such as "comprise" used herein mean that the elements or objects before the words cover the elements or objects listed after the words and their equivalents, and do not exclude other elements or objects.
[0018] The embodiments of the present application provide a liquid level alarm device for a drainage bag, which comprises a storage assembly and a drainage assembly in communication with the storage assembly. The storage assembly comprises a storage box and a storage cover 12 sleeved on the storage box. The storage cover 12 is internally provided with a protrusion in sealing and fitting connection with the inner wall of the storage box. The storage cover 12 is provided with a fixed knob 13 on the side. The storage cover 12 is provided with a liquid level alarm 121. The sensing part of the liquid level alarm 121 is flush with the bottom of the storage cover 12. The bottom of the storage box is provided with a connecting hole in sleeved and matched connection with the drainage assembly. The side of the storage box 11 is provided with scale lines from bottom to top.
[0019] Reference should be made to Figure 1 Figure 2 The drainage assembly is inserted into the abdominal cavity of a patient, and liquid is guided from the drainage assembly into the storage box 11. Before the drainage starts, the fixed state of the storage box 11 can be released by adjusting the fixed knob 13 on the side of the storage cover 12, so that the storage cover 12 can be moved up and down on the storage box 11, so as to control the storage space combined by the storage cover 12 and the storage box 11. After the storage cover 12 is moved to the specified scale line on the storage box 11, the fixed knob 13 is fixed, so that the scale is the specific value of the storage space. After the liquid fills the storage space, the liquid contacts the liquid level alarm 121 at the bottom of the storage cover 12, so as to remind the nursing staff to handle it. The fixed space can avoid the patient from discharging too much liquid.
[0020] In some embodiments, the drainage assembly comprises a drainage tube 21, a fixing sleeve 22, a fixing ring 23, and an elastic sealing pad 24, the fixing sleeve 22 is sleeved on the drainage tube 21, the elastic sealing pad 24 is located on the left side of the fixing sleeve 22, and the fixing ring 23 is fixed on the fixing sleeve 22 by screwing, and the inner diameter of the right side of the elastic sealing pad 24 is larger than that of the left side.
[0021] Referring to Figure 3 Figure 4 The fixing sleeve 22 can avoid the direct contact between the drainage tube 21 and the abdominal wound of the patient, thereby avoiding wound infection. During abdominal drainage, the elastic sealing pad 24 inside the fixing sleeve 22 is poked by the drainage tube 21, and the elastic sealing pad 24 is attached to the periphery of the larger hole diameter, so as to drain the liquid in the abdominal cavity of the human body to the storage assembly. After the drainage is completed, the drainage tube 21 can be pulled back to the other side of the elastic sealing pad 24, and the elastic sealing pad 24 is reset, so as to avoid the backflow of the liquid to the abdominal cavity.
[0022] In some embodiments, the left side of the fixing sleeve 22 is provided with a tapered feature 221 larger than the fixing sleeve 22, and a transverse notch 222 is formed on the left side of the fixing sleeve 22.
[0023] In fact, when the drainage tube 21 pokes through the elastic sealing pad 24, the fixing ring 23 can be fixed on the fixing sleeve 22 by screwing. In addition, the side of the fixing ring 23 close to the tapered feature 221 of the fixing sleeve 22 is provided with a bevel, the fixing ring 23 close to the tapered feature 221 is tightened by rotating the fixing ring 23, thereby extruding the tapered feature 221. Since the tapered feature 221 is provided with the transverse notch 222, when the tapered feature 221 is extruded, the tapered feature 221 moves along the direction perpendicular to the transverse notch 222, so as to fix the drainage tube 21.
[0024] Although the embodiments of the present application have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to the embodiments. However, it should be understood that such modifications and changes all belong to the scope and spirit of the present application described in the claims. Moreover, the present application described herein can have other embodiments, and can be implemented or realized in various ways.
