Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic alarm device for a thoracic and abdominal drainage bag. Background Art
[0002] Pleural and peritoneal effusion is a pathological condition characterized by the abnormal accumulation of fluid within the pleural and abdominal cavities. Increased pleural effusion compresses lung tissue, restricting its expansion and contraction and potentially inducing complications such as atelectasis. This severely impacts the patient's gas exchange capacity, leading to decreased blood oxygen saturation and symptoms such as dyspnea and cyanosis of the lips. Increased peritoneal effusion compresses the gastrointestinal tract, slowing motility and weakening digestive function. Patients may experience symptoms such as loss of appetite, nausea, vomiting, and abdominal distension, and in severe cases, intestinal obstruction.
[0003] Drainage of pleural and peritoneal effusions is an important treatment for pleural and peritoneal effusions. Clinically, the required drainage volume is determined based on the patient's etiology, general condition, and laboratory parameters. During drainage, a drainage bag is connected to the other end of the pleural and peritoneal tube to collect the drained fluid. Overdraining pleural effusions can cause displacement of the mediastinum and trachea, impairing respiratory and circulatory function and leading to symptoms such as palpitations, chest pain, and dyspnea. Overdraining peritoneal effusions can lead to electrolyte imbalances, impairing physiological function, and, in severe cases, even life-threatening complications such as shock. Therefore, drainage of pleural and peritoneal effusions should be tailored to the desired volume. However, a current problem is that when the planned drainage volume is reached, family members or medical staff may neglect to close the drainage tube promptly, resulting in overdrainage and a series of adverse consequences.
[0004] Therefore, how to design an automatic alarm device for thoracic and abdominal drainage bags that can remind family members or medical staff to close the drainage tube in time after the drainage reaches a predetermined amount is a technical problem that has not yet been solved in the existing technology.

[0053] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example
[0054] This embodiment provides an automatic alarm device for chest and abdominal drainage bags, such as Figure 1-5 , 7 and 8, comprising: a main body 1, a water level sensing contact 2 and a control main board 4; wherein the main body 1 has an internal accommodating space; the water level sensing contact 2 comprises a positive contact 21 and a negative contact 22, which is suitable for being fixed to the drainage bag 3 through a fixing structure and can extend into the interior of the drainage bag 3; the control main board 4 is fixedly installed in the internal accommodating space of the main body 1, and can be plugged and connected with the water level sensing contact 2. After the control main board 4 is connected with the water level sensing contact 2, it can receive the water level signal from the water level sensing contact 2 and control the alarm 5 to sound; when the water level in the drainage bag 3 rises to contact both the positive contact 21 and the negative contact 22, the circuit is connected to transmit the water level signal to the control main board 4. After receiving the water level signal, the control main board 4 controls the alarm 5 to sound.
[0055] When used for patients who need to drain pleural and abdominal effusion, first determine the amount of fluid that the patient needs to drain (when the amount of fluid drained by the patient is greater than the capacity of a single drainage bag 3, for example, 5000ml of fluid needs to be drained, the water level sensing contact 2 should be fixed at the 2500ml scale position of the drainage bag 3. When the fluid in the drainage bag 3 reaches this position, the alarm 5 automatically alarms, prompting the family to empty the fluid in the drainage bag 3; then continue drainage until the fluid accumulates to the 2500ml scale position again, and the alarm 5 alarms again. At this time, the family needs to clamp the drainage tube and stop drainage), then insert the water level sensing contact 2 from the position of the corresponding scale indicator line into the drainage bag 3, and fix it to the drainage bag 3 through the fixed structure, and then connect the control main board 4 to the water level sensing contact 2. During drainage, when the water level in drainage bag 3 rises to contact both positive contact 21 and negative contact 22, a circuit is established, transmitting a water level signal to control board 4. Upon receiving the water level signal, control board 4 controls alarm 5 to sound. This embodiment of the automatic alarm device for thoracic and abdominal drainage bags automatically sounds when the level of the accumulated fluid in drainage bag 3 reaches a specified level, alerting the patient to close the drainage tube and stop drainage.
[0056] The main body 1 and the control main board 4 in this embodiment are recyclable and are not disposable items; the water level sensing contact 2 is a disposable item.
[0057] The inventor personally tested the maximum capacity of drainage bags commonly used in hospitals and found it to be 1100ml. When using the automatic alarm device for thoracic and abdominal drainage bags of this embodiment, the water level sensing contact is adjusted to the appropriate scale position based on the patient's desired drainage volume. For example, if a patient requires 5000ml of drainage, the water level sensing contact is adjusted to the 1000ml scale position on the drainage bag. After five repeated drainages, the drainage tube is clamped and drainage is stopped. If a patient requires 4500ml of drainage, the water level sensing contact is adjusted to the 900ml scale position on the drainage bag. After five repeated drainages, the drainage tube is clamped and drainage is stopped.
[0058] like Figure 7 and 8 As shown, the positive contact 21 is a conductive post, fixedly mounted on the inner side of the fixed structure with its axis tilted downward. The negative contact 22 is a conductive sleeve, fixedly mounted on the outer side of the positive contact 21 with its axis tilted downward, and not in contact with the positive contact 21. The water level at which the positive contact 21 contacts the water is higher than the water level at which the negative contact 22 contacts the water. When the accumulated fluid in the drainage bag 3 rises to contact both the positive contact 21 and the negative contact 22, since the accumulated fluid is a conductor, a conductive path is formed between the two contacts, connecting them to the control circuit. The signal of the connection is transmitted via the control circuit to the control board 4, which then controls the alarm 5 to sound.
[0059] like Figure 2 and 3 As shown, the fixing structure includes: a first fixing member 23 and a second fixing member 24; wherein a first adhesive sheet is fixedly provided on the inner side surface of the first fixing member 23, and the water level sensing contact 2 is fixedly provided in the middle of the inner side surface of the first fixing member 23; the first fixing member 23 is suitable for being attached to the position of the hole punched on one side of the drainage bag 3 through the first adhesive sheet, and allowing the water level sensing contact 2 to extend into the interior of the drainage bag 3; a second adhesive sheet is fixedly provided on the inner side surface of the second fixing member 24, and is suitable for being attached to the position of the hole punched on the other side of the drainage bag 3 through the second adhesive sheet. When punching a hole in the drainage bag 3, first determine the amount of accumulated fluid that the patient needs to drain, then punch a hole at the corresponding scale indicator line position of the drainage bag 3, and punch through both sides of the drainage bag 3; attach the first fixing piece 23 to one side of the drainage bag 3 through the first adhesive sheet, seal the punched position, and extend the water level sensing contact 2 from the punched position into the interior of the drainage bag 3; attach the second fixing piece 24 to the other side of the drainage bag 3 through the second adhesive sheet, seal the punched position on the other side to prevent the accumulated fluid from leaking.
[0060] like Figure 6 and 8 As shown, it also includes: a conductor connecting post 7, a conductor sleeve 6 and an insulating socket 61; wherein the conductor connecting post 7 and the positive contact 21 are integrally formed and fixedly arranged on the outer side of the first fixing member 23; the conductor sleeve 6 and the negative contact 22 are integrally formed and fixedly sleeved on the outer side of the conductor connecting post 7, and do not contact the conductor connecting post 7; the insulating socket 61 is fixedly arranged on the control main board 4, and is provided with a connection slot 62 and a connection jack 71 respectively corresponding to the conductor connecting post 7 and the conductor sleeve 6; the bottom of the connection slot 62 is provided with a first connection contact electrically connected to the control main board 4, and the bottom of the connection jack 71 is provided with a second connection contact electrically connected to the control main board 4.
[0061] The main body 1 also includes a connecting through-hole 63, which is coaxially located with and opposite to the conductor sleeve 6 and the insulating socket 61. The conductor sleeve 6 can pass through the connecting through-hole 63 and plug into the connecting slot 62, and the conductor connecting post 7 plugs into the connecting socket 71. After the conductor sleeve 6 plugs into the connecting socket 62, it connects with the first connecting contact and, in turn, with the control main board 4. After the conductor connecting post 7 plugs into the connecting socket 71, it connects with the second connecting contact and, in turn, with the control main board 4. After the conductor sleeve 6 and the conductor connecting post 7 are plugged into and connected to the control main board 4, when the water level in the drainage bag 3 rises to contact both the positive contact 21 and the negative contact 22, the circuit is connected, transmitting a water level signal to the control main board 4. Upon receiving the water level signal, the control main board 4 controls the alarm 5 to sound.
[0062] like Figure 4 As shown, the control main board 4 includes: a control module 41, a receiving module 42, an output module 43 and an alarm 5; wherein the control module 41 is used to control the alarm 5; the receiving module 42 is used to receive the signal from the water level sensing contact 2 and transmit it to the control module 41; the output module 43 is used to transmit the control command of the control module 41 to the alarm 5; the alarm 5 sounds or stops in response to the control of the control module 41. The process of the control main board 4 controlling the alarm 5 to sound is as follows: the receiving module 42 receives the water level signal from the water level sensing contact 2 and transmits the water level signal to the control module 41. After receiving the water level signal, the control module 41 transmits the control command to the alarm 5 through the output module 43. After receiving the command, the alarm 5 sounds an alarm.
[0063] The control mainboard 4 is provided with a switch module 44. A switch button 11 is provided on the main body 1 opposite the switch module 44. The switch button 11 can trigger the switch module 44 to control the start and stop of the control mainboard 4. When the control mainboard 4 needs to be operated, the switch module 44 is triggered by the switch button 11 to turn on the control mainboard 4. When the operation is completed, the switch module 44 is triggered by the switch button 11 to turn off the control mainboard 4.
[0064] like Figure 5 As shown, the device further includes a battery 8, which is electrically connected to the control board 4. The control board 4 is provided with a charging socket 45, which is electrically connected to the battery 8 and is used to charge the battery 8. The main body 1 is provided with a charging through-hole opposite to the charging socket 45. When the battery 8 is low on power, the battery 8 can be charged through the charging socket 45.
[0065] The main body 1 includes a top cover 12 and a base 13, and the top cover 12 and the base 13 are fixedly connected by screw threads. This connection method makes it easy to open the main body 1 for maintenance or repair of the interior.
[0066] The automatic alarm device for pleural and abdominal drainage bags in this embodiment is used as follows: when used on patients with pleural and abdominal effusion, the amount of drainage fluid required by the patient is first determined (when the amount of drainage fluid required by the patient is greater than the capacity of a single drainage bag 3, for example, 5000ml of fluid needs to be drained, the water level sensing contact 2 should be fixed at the 2500ml scale position of the drainage bag 3. When the fluid in the drainage bag 3 reaches this position, the alarm 5 automatically sounds, prompting the family to empty the fluid in the drainage bag 3; then continue drainage until the fluid accumulates to At the 2500ml scale position, the alarm 5 sounds again. At this time, the family members need to clamp the drainage tube and stop drainage). Then, a hole is punched at the position of the scale indicator line. The first fixing member 23 is attached to one side of the drainage bag 3 through the first adhesive sheet to seal the punched position, and the water level sensing contact 2 is extended from the punched position into the drainage bag 3. The second fixing member 24 is attached to the other side of the drainage bag 3 through the second adhesive sheet to seal the punched position on the other side to prevent the accumulated fluid from leaking out. Then, the control main board 4 is connected to the conductor sleeve 6 and the conductor connecting column 7. During the drainage process, when the water level in the drainage bag 3 rises to contact both the positive contact 21 and the negative contact 22, the line is connected to transmit the water level signal to the control main board 4. After receiving the water level signal, the control main board 4 controls the alarm 5 to sound.
[0067] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
