Description

Technical Field

[0001] The invention belongs to the technical field of drainage equipment, and in particular relates to a negative pressure drainage device with an early warning function. Background Art

[0002] Negative pressure suction flow devices are mainly used for medical drainage, expectoration, drainage of dirty blood and secretions, etc. Its main working principle is to use vacuum to generate negative pressure in the cavity and guide the liquid out to achieve the purpose of sewage discharge and purification. Common negative pressure drainage devices drain the liquid in the patient's body through a drainage tube. When the negative pressure terminal is connected, negative pressure is generated in the drain to guide out dirty blood, sputum and other wastes. For example, the gastrointestinal decompression device commonly used in the prior art is mostly placed directly beside the patient's bed when used. When the patient sleeps or moves, it is easy to pull the negative pressure drainage device through the drainage tube, causing the negative pressure drainage device to tip over or fall. In addition, due to the lack of a reminder function, the negative pressure terminal often cannot be closed in time during actual use. After the drainage device is full, overflow will occur under the continuous action of negative pressure, causing pollution, and even damage to the negative pressure terminal. Therefore, it is necessary to improve the existing negative pressure drainage device. Summary of the invention

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] A negative pressure drainage device with an early warning function, such as Figures 1 to 3 As shown, it includes a drainer 1 and a functional frame. A functional column 11 is provided at the upper end of the drainer. With the help of the functional column, the drainer can be easily lifted, which is convenient for the installation and replacement of the drainer. At the same time, the functional column can also play a knocking role. The functional frame includes a tray 2 and a support column 3 on one side of the tray. A horizontal rod 4 is provided at the top of the support column, and a detection device 5 and an alarm device 6 are installed on the horizontal rod; the drainer is placed on the tray and is detachably connected to the frame 7 of the tray through a connecting component 12; a scale mark 8 is provided on the support column, and the support column adopts a telescopic structure, and the lower end of the support column is rotatably installed on the tray.

[0024] In an optional embodiment, the support column includes a lower connecting section 9 and an upper extension section 10, the lower end of the connecting section is rotatably mounted on the frame of the tray, the scale mark is set on the connecting section, and the horizontal rod is set on the top of the extension section. In a further improved solution, the corresponding capacity value is marked next to the scale mark, that is, the total amount of internal liquid corresponding to the current scale mark of the drain can be directly read out, which is clear at a glance and convenient for medical staff to grasp patient information in real time. Compared with the prior art method of estimating the liquid level height in the container and performing formula calculation, it is more accurate and faster.

[0025] In an optional embodiment, the height of the tray frame is 1 / 5-1 / 4 of the total height of the drainer, which can ensure that the drainer remains stable during operation and after being filled with liquid, and will not fall over, and even if there is a certain pulling force from the outside, the drainer will not fall out of the tray. The support column is rotatably mounted on the frame of the tray. When the drainer needs to be installed or removed, the support column can be rotated to rotate the horizontal column (detection device and alarm device) to the outside to avoid collision with the drainer, which is also more convenient for placing and removing the drainer.

[0026] The support column adopts a telescopic structure, which can conveniently and adaptively adjust the height of the horizontal rod, that is, by adjusting the height of the support column, the distance between the horizontal rod and the diverter can be adjusted to meet the actual use needs. The horizontal rod adopts a telescopic rod structure, and the length of the horizontal rod can be conveniently adjusted as needed. For example, the support column adopts a 5mm round rod. The horizontal rod adopts a 5mm wide flat rod, which can be conveniently installed with an alarm device.

[0027] The detection device comprises a distance sensor, and usually, the distance sensor comprises a proximity switch. In an optional embodiment, the distance sensor is connected to a control switch signal of the flow diverter, and at the same time, the distance sensor is connected to an alarm signal.

[0028] The connection assembly includes a detachable spring buckle. The alarm device includes a buzzer alarm. When the distance sensor detects that the distance between the upper end surface of the drain and the horizontal rod is less than the set minimum distance, a signal is sent to the alarm device, and the buzzer alarm emits a buzzer alarm prompt sound to remind relevant personnel to handle it in time.

[0029] The invention has a reasonable structural design. The drainer can be installed in the tray. Under the restriction of the tray frame and the connection components, the drainer can always remain stable during operation and will not fall off the functional frame. When in use, when the distance sensor detects the distance between the upper end surface of the drainer and the horizontal rod is less than the set minimum distance, it will send a signal to the alarm device, and the alarm device will emit a buzzing alarm prompt, which is convenient for medical staff to deal with it in time. In addition, medical staff can conveniently adjust the distance between the horizontal rod and the drainer by adjusting the height of the support column. It has strong versatility and good use effect.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
