Description

Technical Field

[0001] This utility model belongs to the technical field of medical devices, and in particular to a drainage bottle that can monitor the pressure state inside the drainage bottle. Background Technology

[0002] Postoperative drainage techniques for spinal surgery commonly utilize drainage bottles, which consist of a drainage tube and a drainage bulb. The slender end of the drainage tube is connected inside the body cavity, while the other end, the drainage bulb, is placed externally for easy monitoring of the amount of drainage fluid. In clinical practice, to drain intraoperative bleeding, exudate, and tissue exudate, a slender end of a drainage tube is inserted into the surgical cavity before the surgery is completed (i.e., before closing the body cavity). The drainage tube is then sutured to the superficial skin of the patient during the subsequent wound closure, typically secured with 1-2 stitches using sutures for external wounds. The drainage bulb at the other end is an elliptical sphere with negative pressure. Postoperatively, the negative pressure drainage bulb draws blood and tissue exudate through the drainage tube into the bulb. As the fluid volume increases, the pressure inside the bulb decreases until it becomes pressureless. At this point, the fluid inside the bulb needs to be emptied, and clinical nursing staff must constantly monitor and record the fluid volume. Currently, the clinical indication for removing a drainage tube is: drainage fluid ≤50ml / 24h. While the amount of fluid drained is crucial, there is no precise clinical method or equipment for measuring the positive and negative pressure of the drainage bulb to accurately observe when it becomes depressurized and promptly clear the drained fluid. Summary of the Invention

[0003] This invention provides a drainage bottle that can monitor the pressure state inside the drainage bottle. It can promptly and accurately observe when the drainage ball becomes pressureless, clean the body fluid inside the bottle in a timely manner, and monitor the inflow of fluid into the drainage bottle.

[0004] This utility model solves the above-mentioned technical problems through the following technical solutions. A drainage bottle for monitoring the pressure state inside the drainage bottle includes a bottle body, an inlet end, and a monitoring mechanism. The inlet end is located at the top of the bottle body, and the monitoring mechanism is located at the bottom of the bottle body. The monitoring mechanism includes a housing, a weighing sensor, a diaphragm, and an audible and visual alarm device. A connecting cylinder is provided at the bottom of the bottle body, and a diaphragm is provided at the bottom end of the connecting cylinder. The sensing end of the weighing sensor is in contact with the diaphragm, and the signal output end of the weighing sensor is connected to the audible and visual alarm device.

[0005] The aforementioned drainage bottle, which can monitor the pressure state inside the drainage bottle, is also provided with a pressure ring and a top ring. The pressure ring is located on the inner side of the bottom of the connecting cylinder and is fixedly connected to the connecting cylinder. The diaphragm is located under the pressure ring, and the top ring presses the diaphragm against the bottom surface of the pressure ring.

[0006] The aforementioned drainage bottle, which can monitor the pressure state inside the drainage bottle, has an internal thread at the bottom of the connecting cylinder and an external thread on the top ring, which is screwed to the connecting cylinder.

[0007] The aforementioned drainage bottle capable of monitoring the pressure state inside the drainage bottle has an external thread on the outer side of the connecting cylinder, and an internal thread on the top of the housing that matches the external thread of the supporting cylinder. The top of the housing is screwed to the bottom end of the connecting cylinder.

[0008] The aforementioned drainage bottle capable of monitoring the pressure state inside the drainage bottle includes a top cover and a liquid inlet tube at the inlet end. The top of the bottle body is provided with a liquid inlet. The top cover and the liquid inlet are detachably connected. The liquid inlet tube passes through the top cover and communicates with the inside of the bottle body.

[0009] Compared with the prior art, this utility model facilitates the monitoring of the negative pressure state of the drainage ball. As more and more body fluid is drained out of the negative pressure drainage ball, the pressure inside the drainage ball will decrease until it becomes a pressureless state. At this time, the weighing sensor at the end of the placement will be triggered. When the weighing sensor is triggered, the audible and visual alarm will be triggered to remind caregivers and medical staff to monitor the amount of body fluid drained and to clean the body fluid in the bottle in a timely manner.

[0011] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model.

[0012] like Figures 1 to 3This utility model includes a bottle body 1, a liquid inlet, and a monitoring mechanism. The liquid inlet is located at the top of the bottle body 1, and the monitoring mechanism is located at the bottom of the bottle body 1. The monitoring mechanism includes a housing 3, a weighing sensor 4, a diaphragm 5, and an audible and visual alarm device 6. The weighing sensor 4, diaphragm 5, and audible and visual alarm device 6 are housed within the housing 3. A connecting cylinder 7 is located at the bottom of the bottle body 1, and the diaphragm 5 is located at the bottom end of the connecting cylinder 7. The sensing end of the weighing sensor 4 contacts the diaphragm 5, and the signal output end of the weighing sensor 4 is connected to the audible and visual alarm device 6. The bottle body 1 is preferably made of resilient rubber.

[0013] It also includes a pressure ring 9 and a top ring 10. The pressure ring 9 is located on the inner side of the bottom of the connecting cylinder 7 and is fixedly connected to the connecting cylinder 7. The diaphragm 5 is located below the pressure ring 9, and the top ring 10 presses the diaphragm 5 against the bottom surface of the pressure ring 9.

[0014] The bottom of the connecting cylinder 7 is provided with an internal thread, and the top ring 10 is provided with an external thread. The top ring 10 is screwed to the connecting cylinder 7.

[0015] The outer side of the connecting cylinder 7 is provided with an external thread, and the top of the housing 3 is provided with an internal thread that matches the external thread of the support cylinder. The top of the housing 3 is screwed to the bottom end of the connecting cylinder 7.

[0016] The liquid inlet includes a top cover 2 and a liquid inlet pipe 12. The top of the bottle body 1 is provided with a liquid inlet. The top cover 2 is detachably connected to the liquid inlet. The liquid inlet pipe 12 passes through the top cover 2 and communicates with the inside of the bottle body 1.

[0017] Specifically, the audible and visual alarm device 6 includes a detection alarm circuit, an alarm chip, and an LED light. The detection alarm circuit is used to detect the weight of the waste in the container and issue an alarm signal when it exceeds a threshold. The detection alarm circuit includes a weighing sensor 4S, a comparator IC1, a CPU, a transistor T1, and an audible and visual alarm chip. When the drained bodily fluid accumulates in the container, its pressure is transmitted through the diaphragm 5 and sensed by the weighing sensor 4S. The weight signal of the waste in the container is output to the comparator IC1. The reference signal for the weight is provided by the series connection of the first resistor and the second resistor. When the detected weight value exceeds the threshold, i.e., the set maximum storage capacity of the container, the comparator IC1 outputs a signal to the CPU. The CPU processes the signal and outputs an alarm signal to the transistor T1. The transistor T1 is connected as an emitter follower circuit. At this time, the alarm chip BJ is energized and issues an alarm signal. The LED light connected in parallel with it flashes, notifying the caregiver that the container is full and needs to be dealt with promptly.

[0018] The CPU in this invention uses the C8051F340 series chip, which includes two full-duplex serial UARTs with extended baud rate configuration and up to 40 I / O pins, which can fully meet the needs of communication and control with other components; the alarm chip uses the WT588D series voice chip; the comparator IC1 can be MAX941, MAX942, LMV331, LMV393, LM324 or LM358, etc.; the transistor T1 and the LED have no special requirements.

[0019] When in use, first squeeze the bottle body 1 by hand, then tighten the top cap 2 onto the bottle body 1 to create negative pressure in the inlet tube 12. As more and more body fluid is drained, the pressure inside the drainage ball will decrease until it becomes pressureless. At this point, the pressure of the diaphragm 5 will also increase, and the bottom of the diaphragm 5 will touch the weighing sensor 4. When the pressure of the diaphragm 5 reaches a certain value, the weighing sensor 4 will send a signal to the audible and visual alarm device 6 to alert the caregiver.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
