Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an alarm automatic flow cut-off device for a thoracic and abdominal drainage bag. Background Art

[0002] Pleural effusion, that is, pleural effusion and peritoneal effusion, is a common pathological phenomenon in clinical practice. Pleural effusion is actually pleural effusion. The pleural cavity is a closed cavity composed of the visceral pleura and the parietal pleura. In normal people, there is a small amount of fluid in the pleural cavity to act as a lubricant. When the parietal pleura produces too much pleural effusion or the visceral pleura absorbs the pleural effusion slowly due to some reasons such as inflammation and tumors, the fluid in the pleural cavity increases, thus forming pleural effusion. Peritoneal effusion is mainly related to the imbalance of ascites and the exchange of fluid inside and outside the body, the imbalance of fluid exchange inside and outside the blood vessels, and various malignant tumors. When the fluid in the abdominal cavity increases, peritoneal effusion is formed.

[0003] In actual clinical practice, when draining pleural and abdominal effusions for patients, it is not advisable to drain the effusions too quickly or in large quantities. When draining pleural effusions, if the drainage is too fast or a large amount of effusions is drained, it may cause re-expansion pulmonary edema, pleural reaction, and insufficient blood supply to the heart and brain; when draining abdominal effusions, if the drainage is too fast or a large amount of effusions is drained, it may cause electrolyte disorders, hepatic encephalopathy, and insufficient blood supply to the heart and brain. When draining pleural and abdominal effusions for patients, a drainage bag is usually connected to the other end of the thoracoabdominal catheter to collect the drained effusion; refer to Fig.14 As shown, the switch on the drainage tube connected to the existing drainage bag is a clamp-closed type. When clamped, the flow is completely cut off, and when opened, the flow is completely restored. When using this drainage bag, in order to avoid a large amount of drainage of effusion in a short period of time, the drainage tube needs to be clamped intermittently, but the length of the clamping and drainage time is greatly affected by subjective factors and is difficult to accurately grasp. Many patients have serious adverse reactions due to improper operation. In addition, in clinical practice, it is necessary to judge the amount of effusion that the patient needs to drain based on the patient's cause of disease, general condition, and laboratory indicators. Although the existing drainage bag is equipped with a scale indicator line, it is impossible to drain quantitatively. The patient's family members need to manually clamp the drainage tube after the drainage reaches the amount informed by the doctor. However, sometimes the patient's family members may forget to clamp the drainage tube in time, and may also cause the drainage volume to be higher than the amount required by the doctor's order due to subjective feelings and other reasons (reference Fig.15 ), which may lead to adverse consequences.

[0004] Therefore, how to design an alarm automatic shut-off device for thoracic and abdominal drainage bags that can control the flow rate of drained effusion and does not require the patient's family to manually clamp the drainage tube when the amount is reached is a technical problem that has not yet been solved in the prior art. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect that the drainage bag in the prior art cannot control the flow rate and flow rate of the drained effusion, thereby providing an alarm automatic flow cut-off device for the thoracic and abdominal drainage bags that can control the flow rate of the drained effusion and does not require the patient's family to manually clamp the drainage tube when the amount is reached.

[0041] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0042] This embodiment provides an alarm automatic flow cut-off device for chest and abdominal drainage bags, such as Figure 1-12 As shown, it includes: a control part body 1, a control main board 2, a fixed fitting structure, a clamping structure, a series structure and a flow-breaking structure; wherein the control part body 1 has an internal accommodating space, and a switch button 11 is arranged on the top; the control main board 2 is fixedly installed in the accommodating space of the control part body 1, and is provided with a switch module 21, and the switch module 21 is arranged opposite to the switch button 11 and can be triggered by the switch button 11; after the control main board 2 is triggered, it can receive signals, control the sound wave alarm 28 to sound and control the flow-breaking structure to operate; the fixed fitting structure is provided with a water level sensing contact 52, which is suitable for being fixedly fitted to the drainage On the bag, after the fixed fitting structure is fitted onto the drainage bag, the water level sensing contact 52 is inserted into the drainage bag; the water level sensing contact 52 includes a positive contact 520 and a negative contact 521; the clamping structure is used to clamp and fix the control component body 1 to the fixed fitting structure; the series structure is used to electrically connect the water level sensing contact 52 to the control main board 2, so that the control main board 2 can receive the signal from the water level sensing contact 52; the cut-off structure is connected to the control main board 2 through the connecting wire 26, and can be controlled by the control main board 2 to automatically cut off the drainage tube on the drainage bag.

[0043] When the water level in the drainage bag rises to the point where it contacts both contacts of the water level sensing contacts 52, the circuit is connected to transmit the signal to the control main board 2, and the control main board 2 controls the sound wave alarm 28 to sound; when the sound wave alarm 28 continues to alarm for a set time, the control main board 2 controls the cut-off structure to cut off the flow of the drainage tube on the drainage bag.

[0044] When used for patients who need to drain pleural and abdominal effusion, first determine the amount of effusion that the patient needs to drain, then fix the fixed fitting structure to the two sides of the drainage bag relatively, insert the water level sensing contact 52 into the drainage bag from the position of the corresponding scale indicator line, and then snap the control component body 1 onto the fixed fitting structure, and install the cut-off structure onto the drainage tube of the drainage bag. After installation, start the control main board 2. During the drainage process, when the water level in the drainage bag rises to the point where both contacts of the water level sensing contact 52 are in contact, the line is connected to transmit the signal to the control main board 2, and the control main board 2 controls the sound wave alarm 28 to sound; when the sound wave alarm 28 continues to alarm for the set time, the control main board 2 controls the cut-off structure to cut off the drainage tube on the drainage bag, thereby stopping the drainage.

[0045] This embodiment is used for the alarm automatic flow cut-off device of the chest and abdominal drainage bag. When the liquid level of the effusion in the drainage bag reaches the specified position, the sonic alarm 28 automatically alarms to remind the family to clamp the drainage tube and stop the drainage. After the alarm is set for a time, the drainage tube is automatically cut off to avoid the situation where the drainage tube is forgotten to be clamped and cause adverse consequences. In addition, when draining the effusion, the flow rate of the effusion in the drainage tube can also be manually adjusted to avoid the flow rate being too fast and causing adverse reactions.

[0046] The alarm automatic shut-off device for the thoracic and abdominal drainage bag in this embodiment can be recycled and is not a disposable item.

[0047] When using the alarm automatic shut-off device for thoracic and abdominal drainage bags of this embodiment, calculations are performed according to the different drainage volumes required by the patient, and the water level sensing contacts are fixed to the appropriate scale position. For example, if the patient requires drainage of 3000ml, the water level sensing contacts are fixed to the 1000ml scale position of the drainage bag. After repeating the drainage three times, the drainage tube is clamped and the drainage is stopped. If the patient requires drainage of 2500ml, the water level sensing contacts are roughly fixed to the 833ml scale position of the drainage bag. After repeating the drainage three times, the drainage tube is clamped and the drainage is stopped. Reference Fig.16 and 17As shown, the inventor personally tested that the maximum capacity of the drainage bags commonly used in hospitals is 1100ml; in order to avoid multiple dumping of drainage fluid, when draining after connecting multiple drainage bags in series, the maximum capacity of the drainage bag is needed. For example, if 3000ml of drainage is needed, after connecting three drainage bags in series, the water level sensing contact needs to be fixedly installed at the 700ml scale line of the top drainage bag.

[0048] like Figure 3 As shown, the positive contact 520 is a conductor connection column, which is fixedly arranged on the fixed fitting structure with an axis tilted downward, and forms an angle of 10°-50° with the fixed fitting structure, which is 30° in this embodiment; the negative contact 521 is a conductor sleeve, which is fixedly arranged on the outside of the positive contact 520 with an axis tilted downward, and does not contact the positive contact 520. The axis of the conductor sleeve forms an angle of 10°-50° with the fixed fitting structure, which is 30° in this embodiment. When the effusion in the drainage bag rises to contact both contacts, since the effusion is a conductor, a conductive path is formed between the two contacts and connected to the control circuit. The signal of the circuit connection will be transmitted to the control main board 2 via the control circuit.

[0049] like Figure 7 , 9 As shown, the control mainboard 2 includes: a control module 22, a switch module 21, a switch module 23, a receiving module 24, a transmission module 25, a power module 27 and a sound wave alarm 28; wherein the control module 22 is installed on the control mainboard 2, and is used to control the sound wave alarm 28 and the cut-off structure; the switch module 21 is connected to the control module 22, and is used to send a start-stop instruction to the control mainboard 2; the switch module 23 is connected to the control module 22, and is used to manually control the cut-off structure, thereby controlling the on-off of the drainage bag drainage tube; the receiving module 24 is connected to the control mainboard 2 and the series structure, and is used to receive the signal from the water level sensing contact 52 and transmit it to the control mainboard 2; the transmission module 25 is connected to the control mainboard 2 and the connecting wire 26, and is used to transmit the control command to the cut-off structure; the power module 27 is fixedly arranged at the bottom of the control mainboard 2, and is electrically connected to the control mainboard 2; the sound wave alarm 28 is connected to the control mainboard 2, and the maximum volume of the sound wave alarm 28 is 90dB. The control main board 2 is also connected to an indicator light. When the indicator light is on, it means that the control main board 2 is in a working state. When the indicator light is off, it means that the control main board 2 is in a non-working state.
