Description

Technical Field

[0001] The utility model relates to the technical field of chest drainage equipment, in particular to a chest bottle with a built-in liquid level alarm. Background Art

[0002] Thoracic drainage is a drainage method that continuously discharges gas, pus or blood in the chest cavity by inserting special silicone tubes, plastic tubes or surgical chest drainage tubes into the chest cavity. The other end of the drainage tube is connected to a chest drainage bottle for storing the drained pleural effusion. In order to facilitate monitoring by medical staff, a liquid level scale line is provided on one side of the chest drainage bottle. When the liquid level exceeds the normal scale value, medical staff can promptly treat the patient to discharge the abnormal situation. However, this method that relies on manual monitoring not only consumes medical human resources, but may also cause the patient to miss the best time for treatment because the medical staff fails to see in time that the liquid level has reached the monitoring position.

[0003] In order to solve the above problems, a height-adjustable liquid level sensor is usually attached or installed on the chest drainage bottle to replace manual monitoring. For example, a plasma drainage measurement device with application number CN202120370992.2 adopts this structure. However, the device The liquid level sensor is placed outside the chest bottle and can be accidentally touched by passers-by , causing the position of the liquid level sensor to change, thus causing a false alarm. In addition, If the chest drainage bottle falls to the ground, medical staff will not be able to When found To right , the effusion may reflux , causing pneumothorax or infection in patients. Therefore, this still requires medical staff to check regularly and still relies on manual monitoring. Utility Model Content

[0004] In order to solve the technical problems in the above-mentioned background technology that the liquid level sensor on the existing chest bottle is placed on the outside of the chest bottle, which is easily accidentally touched by passers-by, causing the position of the liquid level sensor to change, thereby triggering a false alarm, and when the chest drainage bottle is tipped on the ground, if medical staff fail to discover and right it in time, the accumulated fluid may flow back, causing pneumothorax or infection in the patient, the utility model provides a chest bottle with a built-in liquid level alarm.

[0005] The technical solution of this utility model is as follows:

[0006] A chest bottle with a built-in liquid level alarm includes a drainage bottle body and an alarm provided thereon, and further includes a first liquid level sensing module and a second liquid level sensing module communicatively connected to the alarm. The first liquid level sensing module and the second liquid level sensing module are both non-contact liquid level sensing modules in the prior art.

[0007] The drainage bottle body includes a fluid accumulation chamber, a placement chamber that is not connected to the placement chamber is vertically provided in the fluid accumulation chamber, a support block with a vertical height adjustment is provided in the placement chamber, a first liquid level sensing module is provided on the support block and is arranged toward the fluid accumulation chamber, the first liquid level sensing module is used to detect the liquid level in the fluid accumulation chamber, and when the liquid level reaches a preset value, a signal is sent to the alarm, which alerts medical staff. The design that the placement chamber and the fluid accumulation chamber are not connected to each other avoids bacteria that may be generated in the fluid accumulation chamber and improves safety of use;

[0008] A groove is concavely provided in the middle of the upper side of the effusion chamber, and the second liquid level sensing module is inserted into the groove through the plug-in block. Several second liquid level sensing modules are provided around the outer circle of the plug-in block, and are respectively arranged toward the side wall of the groove on their side. When the drainage bottle body is dumped on the ground, the accumulated fluid in the effusion chamber flows from the bottom to the top of the drainage bottle body. At this time, the second liquid level sensing module can detect the accumulated fluid and send a signal to the alarm. The alarm alerts the medical staff, so that the medical staff can discover the dumping phenomenon in time, straighten it in time, and prevent the accumulated fluid caused by the dumping from flowing back. During use, the chest bottle (a chest bottle with built-in liquid level alarm) does not require medical staff to check regularly. The alarm prompts of the first liquid level sensing module and the second liquid level sensing module replace the manual regular check, saving medical human resources.

[0009] It can be understood that the non-contact liquid level sensing module includes a capacitive liquid level sensor, an ultrasonic liquid level sensor or a separate photoelectric liquid level sensor; the alarm mechanism of the alarm includes a sound alarm or a light alarm, both of which adopt existing technologies and can be selected according to the actual application environment.

[0010] As a preferred implementation method, the drainage bottle body is a rectangular structure, the cross-sectional shape of the groove is a rectangle, and one side thereof is parallel to one side of the drainage bottle body. Four second liquid level sensing modules are located on the side walls around the plug-in block, and are respectively arranged facing the side walls of the groove on their sides. This layout ensures that no matter which side the drainage bottle body tilts, there will be a second liquid level sensing module to monitor it. When the tilted accumulated fluid flows from the bottom to the top of the drainage bottle body, the second liquid level sensing module can quickly detect the presence of accumulated fluid, and once the accumulated fluid is detected, the second liquid level sensing module will immediately send a signal to the alarm. After receiving the signal, the alarm will emit an alarm sound or light to remind medical staff that the drainage bottle body has tilted, so that medical staff can detect abnormal conditions in time and take corresponding measures, such as straightening the drainage bottle body, to avoid possible medical accidents.

[0011] In order to ensure the accuracy of monitoring by the second liquid level sensing module, the maximum vertical distance between the second liquid level sensing module and the outer wall of the groove on its side is set to no more than 10 mm. It can be understood that this refers to the maximum vertical distance between the liquid level sensing probe of the second liquid level sensing module, that is, the sensing part and the outer wall of the groove on its side.

[0012] As a preferred implementation, the drainage bottle body is made of transparent polyethylene. It is understandable that the polyethylene is of medical grade.

[0013] Furthermore, scale lines are provided on the drainage bottle body, the placement chamber is located on the side of the drainage bottle body where the scale lines are provided, and the support block corresponds to the horizontal position of the scale lines, so that medical staff can intuitively observe and adjust the position of the first liquid level sensing module. For example, when used in closed chest drainage, the monitored liquid level height needs to be adjusted to 500ml on the day of surgery, and needs to be adjusted to 700ml the day after the surgery.

[0014] In order to ensure the monitoring accuracy of the first liquid level sensing module, the maximum vertical distance between the first liquid level sensing module and the outer wall of the placement bin is set to no more than 10 mm.

[0015] Furthermore, the groove is located above the scale line, the scale line is located at the lower part of the drainage bottle body, and the groove is located at the upper part of the drainage bottle body, so that the monitoring of the first liquid level sensing module and the second liquid level sensing module do not interfere with each other.

[0016] In the aforementioned breast bottle with built-in liquid level alarm, the support block is driven by a threaded rod.

[0017] Specifically, a threaded rod is vertically provided in the placement bin, and a support block is spirally provided on the threaded rod. Slide grooves are vertically provided on the opposite sides of the placement bin, and protrusions corresponding to the slide grooves are provided on the support block to slide with them. A detachable upper cover is provided on the upper side of the placement bin, and the lower end of the threaded rod is rotatably connected to the bottom of the liquid accumulation chamber, and the upper end is connected to a knob through the upper cover. By turning the knob, the threaded rod is driven to rotate, and then the support block drives the first liquid level sensing module to move vertically in the placement bin, thereby realizing the adjustment of the first liquid level sensing module.

[0018] The beneficial effect of the present invention lies in that, by setting a placement bin which is not connected to the fluid accumulation cavity of the drainage bottle body, and setting the first liquid level sensing module for monitoring the fluid accumulation in the fluid accumulation cavity in the placement bin, compared with placing the first liquid level sensing module on the outside of the drainage bottle body, the situation where pedestrians accidentally touch the first liquid level sensing module is eliminated. This design reduces false alarms and significantly improves the accuracy of monitoring; at the same time, through the setting and layout of the second liquid level sensing module, when the drainage bottle body falls over, the second liquid level sensing module can quickly detect this abnormal situation and immediately remind medical staff through the alarm, so that medical staff can quickly discover the abnormal state of the drainage bottle body and take corresponding measures to effectively avoid possible medical accidents. Therefore, the monitoring work of the chest bottle does not need to rely on manual labor and significantly improves the accuracy of monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Combine Figure 1This embodiment provides a chest bottle with a built-in liquid level alarm, including a drainage bottle body 1 and an alarm 2 arranged thereon, and also including a first liquid level sensing module and a second liquid level sensing module communicatively connected to the alarm 2, wherein the first liquid level sensing module is used to monitor the liquid level height in the fluid accumulation cavity 11, and the second liquid level sensing module is used to monitor whether the drainage bottle body 1 is tilted, and the first liquid level sensing module and the second liquid level sensing module are both non-contact liquid level sensing modules in the prior art.

[0029] It can be understood that the non-contact liquid level sensing module includes a capacitive liquid level sensor, an ultrasonic liquid level sensor or a separate photoelectric liquid level sensor; the alarm mechanism of the alarm 2 includes a sound alarm or a light alarm, both of which adopt existing technologies and can be selected according to the actual application environment.

[0030] Combine Figure 2 As for the setting of the first liquid level sensing module, the drainage bottle body 1 includes a fluid accumulation chamber 11, and a placement bin 12 that is not connected to the fluid accumulation chamber 11 is vertically provided in the fluid accumulation chamber 11. A support block 3 with adjustable vertical height is provided in the placement bin 12. The first liquid level sensing module is arranged on the support block 3 and is arranged toward the fluid accumulation chamber 11. The first liquid level sensing module is used to detect the liquid level height in the fluid accumulation chamber 11. When the liquid level reaches a preset value, a signal is sent to the alarm 2. The alarm 2 alarms to remind medical staff. Among them, the design that the placement bin 12 and the fluid accumulation chamber 11 are not connected to each other avoids the bacteria that may be generated in the fluid accumulation chamber 11 and improves the safety of use.

[0031] Combine Figure 3 and Figure 6 The support block 3 is driven by a threaded rod 4. A threaded rod 4 is vertically provided in the placement bin 12. The support block 3 is spirally arranged on the threaded rod 4. Slide grooves are vertically provided on the opposite sides of the placement bin 12. The corresponding slide grooves on the support block 3 are provided with protrusions that slide with them. A detachable upper cover 13 is provided on the upper side of the placement bin 12. The lower end of the threaded rod 4 is rotatably connected to the bottom of the liquid accumulation chamber 11, and the upper end is connected to a knob 6 through the upper cover 13. When adjusting the monitoring height of the first liquid level sensor, by turning the knob 6, the threaded rod 4 is driven to rotate, and then the support block 3 is driven to drive the first liquid level sensing module to move vertically in the placement bin 12, thereby realizing the adjustment of the first liquid level sensing module.

[0032] Combine Figure 3The drainage bottle body 1 is made of medical-grade transparent polyethylene. A scale line is provided on the vertical direction of an outer wall of the drainage bottle body 1. The placement bin 12 is located on the side of the drainage bottle body 1 where the scale line is provided, and the support block 3 corresponds to the horizontal position of the scale line, so that medical staff can intuitively observe and adjust the position of the first liquid level sensing module. For example, when used in closed chest drainage, the monitored liquid level height needs to be adjusted to 500 ml on the day of surgery, and needs to be adjusted to 700 ml the day after surgery.

[0033] The maximum vertical distance between the first liquid level sensing module and the outer side wall of the placement chamber 12 does not exceed 10 mm to avoid the monitoring distance being too large, thereby ensuring the accuracy of the monitoring by the first liquid level sensing module.

[0034] Combine Figure 2 、 Figure 4 and Figure 5 Specifically, the setting of the second liquid level sensing module is that a groove 111 is concave in the middle of the upper side of the effusion chamber 11, and the second liquid level sensing module is inserted into the groove 111 through the plug-in block 5. Several second liquid level sensing modules are provided around the outer circle of the plug-in block 5, and are respectively arranged toward the side wall of the groove 111 on their side. When the drainage bottle body 1 falls to the ground, the accumulated fluid in the effusion chamber 11 flows from the bottom to the top of the drainage bottle body 1. At this time, the second liquid level sensing module can detect the accumulated fluid and send a signal to the alarm 2. The alarm 2 alarms to remind medical staff, so that medical staff can discover the tipping phenomenon in time, straighten it in time, and prevent the accumulated fluid caused by the tipping from flowing back. During use, the chest bottle (a chest bottle with built-in liquid level alarm) does not require medical staff to check regularly. The alarm prompts of the first liquid level sensing module and the second liquid level sensing module replace the manual regular check, saving medical human resources.

[0035] In this embodiment, the drainage bottle body 1 is a rectangular structure, and the cross-sectional shape of the groove 111 is a rectangle, one side of which is parallel to the side of the drainage bottle body 1. Four second liquid level sensing modules are located on the side walls around the plug-in block 5, and are respectively arranged facing the side walls of the groove 111 on their sides. This layout ensures that no matter which side the drainage bottle body 1 tilts, there will be a second liquid level sensing module to monitor it. When the tilted accumulated fluid flows from the bottom to the top of the drainage bottle body 1, the second liquid level sensing module can quickly detect the presence of accumulated fluid, and once the accumulated fluid is detected, the second liquid level sensing module will immediately send a signal to the alarm 2. After receiving the signal, the alarm 2 will emit an alarm sound or light to remind medical staff that the drainage bottle body 1 has tilted, so that medical staff can detect abnormal conditions in time and take corresponding measures, such as straightening the drainage bottle body, to avoid possible medical accidents.

[0036] The maximum vertical distance between the second liquid level sensing module and the outer wall of the groove 111 on its side does not exceed 10 mm to ensure the accuracy of monitoring by the second liquid level sensing module. It can be understood that what is referred to here is the liquid level sensing probe of the second liquid level sensing module, that is, the maximum vertical distance between the sensing part of the second liquid level sensing module and the outer wall of the groove 111 on its side.

[0037] In this embodiment, the groove 111 is located above the scale line, the scale line is located at the lower part of the drainage bottle body 1, and the groove 111 is located at the upper part of the drainage bottle body 1, so that the monitoring of the first liquid level sensing module and the second liquid level sensing module do not interfere with each other.

[0038] To facilitate processing and disassembly and assembly between various parts, the support block 3, the plug-in block 5, the screw and the knob 6 are all made of the same material as the drainage bottle body 1, that is, medical-grade transparent polyethylene material. This material not only has good processing performance, but also meets the strict standards of the medical industry, ensuring the quality and safety of the chest bottle. The upper part of the placement bin 12 is located in the groove 111, and the plug-in block 5 is provided with an upper cover 13 air-avoidance opening corresponding to the upper cover 13. This design enables the upper cover 13 to be smoothly installed on the drainage bottle body 1, and the alarm 2 is provided on the upper side of the plug-in block 5. When the drainage bottle body 1 is tilted or the fluid accumulation is abnormal, the alarm 2 can respond quickly and emit an alarm sound or light to remind medical staff to deal with it in time. This layout not only ensures the effectiveness of the alarm 2, but also avoids its interference with the operation of medical staff.
