Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an electronic water seal bottle and a use method thereof. Background Art

[0002] Water seal bottle, scientifically known as chest drainage device, is mainly used in surgical operations for chest drainage. Through the pipeline, the effusion or gas in the patient's chest cavity is drained to the bottle. Currently, passive single-chamber bottles or multi-chamber bottles are used for gas and liquid collection. This type of product has no sensing, no measurement, and no self-control function. Medical staff need to make frequent inspections, the workload of nurses increases, and patients often have to extubate and intubate multiple times, which adds mental and economic burdens.

[0003] For example, CN213911651 U discloses a water seal bottle with a constant liquid level, including a water seal bottle body, a chest drainage tube and a vent, wherein the water seal bottle body contains disinfectant, the top of the water seal bottle body has a jack for the chest drainage tube to pass through, and the chest drainage tube is immersed in the disinfectant in the water seal bottle body, and also includes a fluid effusion bottle sleeved on the outside of the water seal bottle body, the fluid effusion bottle and the water seal bottle body form a whole, and a liquid storage cavity is formed between the outside of the water seal bottle body and the inside of the fluid effusion bottle, and the side of the water seal bottle body is provided with a drain port that passes through the liquid storage cavity; the utility model has a simple structure and is easy to use. Through the provision of the fluid effusion bottle and the drain port, the liquid level in the water seal bottle body is relatively constant, thereby avoiding the liquid level in the water seal bottle body exceeding the highest range of the chest drainage tube outlet plane, resulting in the situation that the gas in the chest cavity is difficult to be discharged, thereby reducing the medical risks caused by untimely treatment by medical personnel. This product is still a passive device without monitoring and self-control functions.

[0004] Another example is CN211157576U, which provides a new water seal bottle, including a water seal bottle, a drainage tube, a three-way tube, a drainage bag and a water seal bottle bracket; a water seal bottle bracket is arranged outside the water seal bottle, and a hook is arranged on the left and right sides of the water seal bottle bracket, respectively; the water seal bottle is connected to one side of the three-way tube through the drainage tube, and the other interface of the three-way tube is connected to the chest drainage tube, and the remaining three-way tube interface is connected to the drainage bag through the drainage tube, and the height of the drainage tube on one side of the drainage bag is lower than the height of the drainage tube at the end of the water seal bottle, and the three-way tube is made of silicone rubber or polyurethane, and the three-way tube is connected to the water seal bottle and the drainage bag side, respectively, and a switch valve is arranged. On the basis of the original water seal bottle, the utility model connects another drainage tube to the drainage tube side, connects the drainage bag below, and is connected by a three-way tube in the middle, so that a large amount of flushing fluid flows into the drainage bag on one side, and the liquid in the drainage bag can be dumped at any time, so as to reduce the replacement of water seal bottles and reduce the cost burden of patients. The above problems also exist. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides an electronic water seal bottle with monitoring and automatic control functions and a method for using the same.

[0006] To achieve the above objectives, the present invention discloses an electronic water seal bottle, comprising:

[0007] The water seal bottle body has at least one cavity. The water seal bottle body 1 is provided with a liquid / gas inlet pipe member penetrating the cavity wall thereof. The portion of the liquid / gas inlet pipe member extending outside the water seal bottle body is used as a liquid inlet for connecting a chest drainage tube. The other end outlet of the liquid / gas inlet pipe member located in the cavity of the water seal bottle body is located at the lower part of the cavity of the water seal bottle body and below the liquid level in the cavity.

[0008] The main control device includes:

[0009] An air outlet pipeline, the lower inlet of which is located in the cavity and above the liquid level in the cavity, and the upper outlet of which extends out of the water seal bottle body;

[0010] An air pump, used to draw the air in the cavity out of the cavity through an air outlet pipeline to form a negative pressure in the cavity, and the air pump is connected to the air outlet pipeline;

[0011] The external pressure sensor is installed outside the water seal bottle.

[0012] An internal pressure sensor is disposed in the main body cavity of the water seal bottle and is located above the liquid level in the cavity;

[0013] The control device is connected to the external pressure sensor and the internal pressure sensor signals, receives the external pressure value and the internal pressure value transmitted by the external pressure sensor and the internal pressure sensor, and calculates the pressure difference between the two to control the start and stop of the air pump.

[0014] The electronic water seal bottle provided by the present invention integrates the function of detecting the internal and external pressures of the water seal bottle cavity, and can decide whether to start the air pump according to whether the internal and external pressure difference exceeds a set value. The electronic water seal bottle has the functions of automatic detection and automatic control, which greatly reduces the workload of medical staff and also provides a basis for expanding functions such as adding alarms.

[0015] Furthermore, a main control cabin is provided on the upper part of the water seal bottle body, the air pump is arranged in the main control cabin, the air outlet pipeline runs through the main control cabin, and the air pump is bridged in the air outlet pipeline through its inlet and outlet.

[0016] Furthermore, the main control device also includes a power module for providing power to the main control device, and the power module is also arranged in the main control cabin.

[0017] Furthermore, the main control cabin is sealed and arranged at the upper part of the cavity, the upper wall of the main control cabin is a part of the upper wall of the water seal bottle body, and the internal pressure sensor is arranged on the outer wall of the main control cabin located in the cavity.

[0018] Furthermore, a filter component is provided at the lower inlet of the air outlet pipeline.

[0019] Furthermore, a floating plate adapted to the cross-sectional shape of the cavity is provided in the cavity, the floating plate floats on the liquid surface in the cavity, the floating plate is provided with a through hole, the liquid / air inlet pipe passes through the through hole, and the floating plate moves up and down following the liquid surface.

[0020] Furthermore, the floating plate is provided with an exhaust hole.

[0021] Furthermore, the exhaust hole has an upwardly extending convex edge or pipeline, and the upper end of the convex edge or pipeline is provided with a unidirectional elastic diaphragm or a filter membrane layer that allows gas to pass but liquid to not pass, which only allows airflow to be discharged from the lower side of the floating plate through the exhaust hole and out of the upper end.

[0022] The present invention also provides a method for using the electronic water seal bottle, comprising the following steps:

[0023] S1, connect the liquid / air inlet pipe to the chest drainage tube. As the chest cavity discharges gas or liquid from the body under the action of breathing, it enters the water seal bottle;

[0024] S2, the internal pressure of the water seal bottle increases, causing the water column in the liquid / air pipe to increase. When the water column increases to the expected value (1-3cm, depending on the situation), turn on the power switch of the electronic water seal bottle; at this time, the height of the water column is to maintain a suitable negative pressure in the chest cavity. As the subsequent drainage or exhaust causes the pressure in the bottle cavity to increase, the exhaust method must be sampled and exhausted to the outside. Therefore, the power switch is started in advance to enter the working state.

[0025] S3, calculating the negative pressure value inside the cavity of the electronic water seal bottle body through the external pressure value and the internal pressure value obtained by the external pressure sensor and the internal pressure sensor, and maintaining the negative pressure value;

[0026] S4, monitor the negative pressure value inside the cavity of the electronic water seal bottle body and see that it increases and exceeds the internal set value, start the air pump to discharge the gas and maintain the negative pressure in the chest cavity. When the liquid is drained out, the float plate floats up, and when the gas is drained out, the gas is discharged into the upper space of the cavity of the water seal bottle body through the exhaust hole.

[0027] The present invention first utilizes the pressure of the patient's chest breathing to discharge the gas and / or liquid into the cavity of the electronic water seal bottle through the liquid inlet / air pipe fitting, and utilizes the closed state on one side of the cavity to compress the air in the upper part of the cavity and increase the pressure, thereby forming a liquid column in the liquid inlet / air pipe fitting that is higher than the liquid level in the cavity. When the height difference between the liquid column and the liquid level in the cavity reaches a predetermined height, the internal and external pressure difference reaches a preset value, and the main control device starts the electronic water seal bottle and starts the air pump to extract the gas and liquid in the chest cavity. The device can automatically control the timing of starting and stopping the air pump, maintain the negative pressure of the chest cavity within a predetermined range, and ensure that the gas and liquid in the chest cavity can be extracted in time, which greatly reduces the workload of medical staff and improves safety and convenience.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention will be further described below in conjunction with the embodiments.

[0033] In some embodiments, please refer to the attached instructions. Figure 1 , an electronic water seal bottle, comprising:

[0034] The water seal bottle body 1 has at least one cavity. Figure 1The example is a cavity, the water seal bottle body 1 is provided with a liquid / air inlet pipe 5 penetrating the cavity wall thereof, the portion of the liquid / air inlet pipe 5 extending outside the water seal bottle body 1 is used as a liquid inlet for connecting a chest drainage tube, the other end outlet of the liquid / air inlet pipe 5 located in the cavity of the water seal bottle body 1 is located at the lower part of the cavity of the water seal bottle body 1 and below the liquid level in the cavity;

[0035] The main control device includes:

[0036] The air outlet pipeline 9 has a lower inlet located in the cavity and above the liquid level in the cavity, and an upper outlet extending out of the water seal bottle body 1;

[0037] An air pump 10, used to pump the air in the cavity out of the cavity through the air outlet pipe 9 to form a negative pressure in the cavity, and the air pump 10 is connected to the air outlet pipe 9;

[0038] The external pressure sensor 6 is arranged outside the water seal bottle body 1.

[0039] The internal pressure sensor 14 is arranged in the cavity of the water seal bottle body 1 and is located above the liquid level in the cavity;

[0040] The control device is connected to the external pressure sensor 6 and the internal pressure sensor 14 signals, receives the external pressure value and the internal pressure value transmitted by the external pressure sensor 6 and the internal pressure sensor 14, and calculates the pressure difference between the two to control the start and stop of the air pump.

[0041] The electronic water seal bottle provided by the present invention integrates the function of detecting the internal and external pressures of the water seal bottle cavity, and can decide whether to start the air pump according to whether the internal and external pressure difference exceeds a set value. The electronic water seal bottle has the functions of automatic detection and automatic control, which greatly reduces the workload of medical staff and also provides a basis for expanding functions such as adding alarms.

[0042] In some embodiments, in order to make the product more compact and beautiful, a main control cabin is provided at the upper part of the water seal bottle body 1, and the main control device including the circuit board 11, the air pump 10 and other main components are arranged in the main control cabin 12, the air outlet pipe 9 runs through the main control cabin, and the air pump 10 is bridged in the air outlet pipe 9 through its inlet and outlet. For the sake of the regular appearance, it is preferred to seal the main control cabin 12 at the upper part of the cavity, and the upper wall of the main control cabin is a part of the upper wall of the water seal bottle body 1, and the internal pressure sensor is arranged on the outer wall of the main control cabin located in the cavity. The cabin of the main control cabin 12 is in a sealed isolation state with the cavity of the water seal bottle body, which can protect the main control device and avoid polluting the environment in the cavity. The upper wall of the main control cabin 12 and the water seal bottle body 1 can share a part of the bottle body, and part of the bottle body can be detachably fastened and connected using buckles or screws, which is convenient for repairing the main control device.

[0043] In addition, the main control device also includes a power module 8 for providing power to the main control device, and the power module 8 is also arranged in the main control cabin. The power module 8 can be selected as a lithium battery for repeated charging and repeated use. It can also be connected to an external power supply for long-term continuous work.

[0044] In some embodiments, a filter component is provided at the lower entrance of the air outlet pipe 9, for example, a filter membrane 13 that can prevent viruses and bacteria from passing through can be provided. In this way, the internal and external environments of the cavity can be isolated to avoid cross contamination between the internal and external environments.

[0045] In some embodiments, a floating plate 16 adapted to the cross-sectional shape of the cavity is provided in the cavity, and the floating plate 16 floats on the liquid surface of the liquid 17 in the cavity. A through hole is provided on the floating plate 16, and the liquid / gas inlet pipe 5 passes through the through hole, and the floating plate 16 moves up and down following the liquid surface. A flow channel through which gas can pass is provided between the floating plate 16 and the cavity, such as the gap between the exhaust hole 15 or the inner wall of the cavity, or the gap between the through hole and the liquid / gas inlet pipe 5. The provision of the floating plate is conducive to isolating the liquid part in the lower part of the cavity and the gas part in the upper part, preventing gas and liquid splashing and contaminating the upper device. At the same time, when the water seal bottle is accidentally tipped over, the flow of liquid to the upper space is greatly delayed. After timely straightening, the upper device will not be contaminated by liquid and must be replaced as in the prior art.

[0046] In some embodiments, the floating plate 16 is provided with an exhaust hole 15 .

[0047] Furthermore, the exhaust hole 15 has an upwardly extending convex edge or pipeline, and the upper end of the convex edge or pipeline is provided with a unidirectional elastic membrane that only allows airflow to pass from the lower side of the floating plate through the exhaust hole 15 and be discharged from the upper end. A filter membrane layer that allows gas to pass but liquid cannot pass can also be provided on the convex edge or pipeline.

[0048] On this basis, a piston-like sliding sealing structure can be used between the side wall of the float plate and the inner wall of the cavity, and a similar sliding sealing structure can also be used between the through hole and the liquid / air inlet pipe 5, for example, one or more layers of sealing rings can be set, which can further enhance the protection capability of the present invention in the event of an accidental rollover.

[0049] Attached Figure 1 In the example, hooks 3 and hanging ropes 7 connected to the hooks 3 are also provided on the upper parts of both sides of the water seal bottle body 1, and anti-slip and shock-absorbing foot pads 2 are provided on the bottom of the water seal bottle body 1.

[0050] When the pipeline is blocked or the air pump fails, the internal and external pressure difference will exceed the preset range. This can be used as an alarm signal to add an alarm device to provide sound, light, remote alarm, etc. Figure 1 The fault warning light 4 in the example is to facilitate timely treatment by medical staff.

[0051] The present invention also provides a method for using the electronic water seal bottle, comprising the following steps:

[0052] S1, connect the liquid / air inlet pipe 5 to the chest drainage tube, and the chest cavity discharges gas or liquid from the body under the action of breathing and enters the water seal bottle;

[0053] S2, the internal pressure of the water seal bottle increases, causing the water column in the liquid / air inlet pipe 5 to increase. When the water column increases to the expected value (1-3cm, depending on the situation), turn on the power switch of the electronic water seal bottle; at this time, the height of the water column is to maintain a suitable negative pressure in the chest cavity. As the subsequent drainage or exhaust causes the pressure in the bottle cavity to increase, the exhaust method must be sampled and exhausted to the outside. Therefore, the power switch is started in advance to enter the working state.

[0054] S3, calculating the negative pressure value inside the cavity of the electronic water seal bottle body 1 through the external pressure value and the internal pressure value obtained by the external pressure sensor 6 and the internal pressure sensor 14, and maintaining the negative pressure value;

[0055] S4, monitor the negative pressure value inside the cavity of the electronic water seal bottle body 1 and it increases and exceeds the internal set value (the water column in the tube 5 becomes higher and exceeds the set value), start the air pump 10 to discharge the gas, maintain the negative pressure in the chest cavity, when the liquid is drained out, the float plate 16 floats up, and when the gas is drained out, the gas is discharged into the upper space of the cavity of the water seal bottle body through the exhaust hole 15.

[0056] The present invention first utilizes the pressure of the patient's chest breathing to discharge the gas and / or liquid into the cavity of the electronic water seal bottle through the liquid inlet / air pipe fitting 5, and utilizes the closed state on one side of the cavity to compress the air in the upper part of the cavity and increase the pressure, thereby forming a liquid column higher than the liquid level in the cavity in the liquid inlet / air pipe fitting 5. When the height difference between the liquid column and the liquid level in the cavity reaches a predetermined height, the internal and external pressure difference reaches a preset value, and the main control device starts the electronic water seal bottle and starts the air pump to extract the gas and liquid in the chest cavity. The device can automatically control the timing of starting and stopping the air pump, maintain the negative pressure of the chest cavity within a predetermined range, and ensure that the gas and liquid in the chest cavity can be extracted in time, which greatly reduces the workload of medical staff and improves safety and convenience.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
