[0021] Preferred embodiments of the present invention are described in detail with reference to Figures 1 to 5. The description serves only to explain the embodiments of the present invention, by way of illustration and not limitation.

[0022] As shown in [Fig.1] and [Fig.2], a drainage bottle system 100 according to an embodiment of the present invention comprises: a system housing 1, a drainage bottle 2, a drainage tube 3, a motorless suction device 4 and a liquid detection device 5.

[0023] As shown in Figures 1 and 2, a drainage element layout space 10 is formed inside the system housing 1. The drainage element layout space 10 is used for the motorless suction device 4 and the liquid sensing device 5.

[0024] As shown in Figures 1 and 2, the drainage bottle 2 is mounted on the system housing 1. The drainage bottle 2 is used to contain fluid drained during a chest drainage procedure. Preferably, to facilitate visual and instrumental observation of the fluid collected in the drainage bottle 2, the drainage bottle 2 is made of a transparent material in this embodiment.

[0025] As shown in Figures 1 and 2, the drainage tube 3, which is disposed on the system housing 1, has a suction end 31 extending outside the system housing 1 and a collection end 32 connected to the drainage bottle 2 through the system housing 1. The suction end 31 is used to be connected to a patient so that the chest drainage procedure can be performed on the patient using the drainage tube 3.

[0026] More specifically, in this embodiment, the system housing 1 has a front outer surface as a drainage bottle mounting surface 11 on which the drainage bottle 2 is mounted, the collection end 32 of the drainage tube 3 extending through the drainage element arrangement space 10 to the drainage bottle mounting surface 11 to be connected to the bottle of drainage 2.

[0027] As shown in Figures 1 and 2, the motorless suction device 4, which is disposed in the drainage element disposition space 10, comprises a piezoelectric suction pump 41 and a drive circuit 42, the piezoelectric suction pump 41 being connected to the drainage tube 3, the drive circuit 42 being coupled to the piezoelectric suction pump 41 and being configured to drive the piezoelectric suction pump 41 such that the piezoelectric suction pump 41 generates a negative pressure by means of a piezoelectric effect to cause the drainage tube 3 to draw a detectable liquid L from the suction end 31 to the collection end 32, thus collecting the detectable liquid L through the drainage tube 3 into the drainage bottle 2.

[0028] More specifically, in this embodiment, the motorless suction device 4 further comprises a suction tube 43, one end of the suction tube 43 is connected to the piezoelectric suction pump 41, the other end of the suction tube 43 extends to the mounting surface of the drainage bottle 11 to be connected to the drainage bottle 2, and the piezoelectric suction pump 41 is thus connected to the drainage tube 3 via the suction tube 43 and the drainage bottle 2, the piezoelectric suction pump 41 being configured to generate the negative pressure in the drainage bottle 2 such that the liquid to be detected L is aspirated and collected in the drainage bottle 2 via the drainage tube 3.It goes without saying that the present invention is not limited to this and that the motorless suction device 4 could also use other types of piping configurations to achieve the function of driving the drainage tube 3 for suction.

[0029] Furthermore, as shown in [Fig.3] and [Fig.4], in this embodiment, the piezoelectric suction pump 41 mainly comprises a piezoelectric element 411 and a membrane element 412 to which the piezoelectric element 411 is attached. When driven by the drive circuit 42, as shown in [Fig. 3], the piezoelectric element 411 stretches to bend the membrane element 412 downwards in a deformed manner, and the volume of an internal space of the piezoelectric suction pump 41 is thus enlarged such that air in the drainage bottle 2 ([Fig. 2]) is drawn into the internal space of the piezoelectric suction pump 41 via the suction tube 43, thereby generating negative pressure in the drainage bottle 2, whereby the liquid to be detected L is drawn in and collected in the drainage bottle 2 via the drainage tube 3. Then ... volume of the internal space of the piezoelectric suction pump 41 is increased.4], when the piezoelectric element 411 retracts to reverse-bend the membrane element 412 in an upward deformed manner, the volume of the internal space of the piezo suction pump. The electrical pressure 41 is reduced such that the air in the piezoelectric suction pump 41 is expelled and discharged from the system housing 1 via an exhaust tube 44. Preferably, the piezoelectric suction pump 41 is a ceramic piezoelectric suction pump that uses mechanical deformation of a piezoelectric ceramic (i.e., the piezoelectric element 411) of the piezoelectric suction pump to generate the negative pressure. Furthermore, in this embodiment, the drive circuit 42 is configured to drive the piezoelectric suction pump 41 with a sinusoidal wave signal or a square wave signal. The sinusoidal wave signal is, for example, a sinusoidal wave signal or a cosine wave signal.

In the drainage bottle system 100 according to the present invention, the motorless suction device 4 operates with extremely low noise and without electromagnetic interference, which effectively avoids patient discomfort, and can be applied to various medical fields without concern for electromagnetic interference, thus effectively resolving the technical problems of the prior art.

[0033] In particular, the fluid level and color of the fluid to be detected L can be used for diagnosis, and by providing the fluid level sensor 51 and the fluid color sensor 52, it is convenient to obtain the information immediately after the chest drainage procedure. Furthermore, a sampling area 21 can be provided inside the drainage bottle 2. When the fluid to be detected L is aspirated into the drainage bottle 2, it first flows into the sampling area 21 to facilitate inspection and sampling by healthcare personnel. When the fluid in the sampling area 21 exceeds a design height, it flows back into the drainage bottle 2.Furthermore, the drainage bottle 2 is preferably mounted on the system housing 1 in a removable manner to facilitate replacement with a new drainage bottle for each chest drainage procedure. In addition, each drainage bottle may have an identification label on it, and by detecting the label identification code of the identification label with the label image recognition sensor 53, information (i.e., the label identification information) concerning the drainage bottle and / or the chest drainage procedure can be quickly obtained. Furthermore, in this embodiment, the fluid level sensor 51 may be a capacitive fluid level sensor, a fluid level image sensor, or a sensor that detects the fluid level in any other known manner.Similarly, the liquid color sensor 52 and the label image recognition sensor 53 can each be of various types of sensors that detect in any known way, and the present invention is not limited to these.

[0035] More specifically, the cloud transmission device 6 can transmit liquid detection information to the DI cloud data analysis device via a wired or wireless network, thereby enabling the DI cloud data analysis device to perform big data analysis and diversified management based on liquid detection information collected from multiple parties. Liquid detection information can include liquid level information, liquid color information, and other information. label identification formations, or information related to or derived from them.
