Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure drainage, in particular to a negative pressure drainage device with visualized negative pressure value. Background Art

[0002] Negative pressure drainage has been widely used in various types of postoperative care in clinical practice to discharge wound secretions and exudate. It is often used in the care of traumatic and postoperative wounds, chronic ulcers and other wounds. By connecting the tube to the wound, the principle of negative pressure is used to help promote wound healing and reduce infection. It usually includes a negative pressure ball, drainage tube, and drainage tube. Negative pressure drainage helps reduce the risk of infection and promote wound healing by helping to maintain a clean and moist environment around the wound and promoting blood circulation and cell growth. It is also used to treat some serious trauma or postoperative complications.

[0003] The commonly used simple negative pressure drainage device currently produces negative pressure and drainage by medical staff squeezing the negative pressure ball, and the degree of squeezing is judged based on experience, and there is no accurate negative pressure value data. This negative pressure drainage device currently has the following main problems:

[0004] (1) When squeezing the negative pressure ball for negative pressure drainage, medical staff may use too little or too little force, but fail to take timely measures to prevent the inappropriate negative pressure from continuing to affect the patient's wound, thus prolonging the healing time of the patient's wound;

[0005] (2) When squeezing the negative pressure ball for negative pressure drainage, the specific negative pressure value is unclear and the negative pressure can only be increased based on experience and feeling. This lacks scientificity and requires medical staff to have a better control of the negative pressure value, which increases the workload of medical staff.

[0006] (3) The negative pressure value cannot be accurately recorded during use, making it difficult to monitor and track wound healing. This may affect medical staff's judgment of the patient's wound status and nursing decisions, making it impossible to adjust the treatment plan in a timely manner, thereby affecting the treatment effect and the patient's recovery process.

[0007] Therefore, we need to develop a negative pressure drainage device with visualized negative pressure values, which can accurately display the negative pressure value data and control the negative pressure within an appropriate range, record the changes in negative pressure values, and ensure the safety of patients.

Obviously, the described embodiment is one embodiment of the utility model, not all embodiments of the utility model. Based on this embodiment of the utility model, all other embodiments of the utility model obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The present invention is described in detail below in conjunction with specific embodiments:

[0041] As attached Figure 1 The figure shows a schematic structural diagram of a negative pressure drainage device with a visualized negative pressure value provided by an embodiment of the utility model, which includes the following structures:

[0042] Drainage tube 1, negative pressure ball 2, drainage tube 3, negative pressure sensing device 4, display 5, negative pressure control module 6;

[0043] The drainage tube 1 is connected to the upper end of the negative pressure ball 2, the drainage tube 3 is connected to the lower end of the negative pressure ball 2, and the negative pressure sensing device 4 is installed on the negative pressure ball 2 and connected to the display 5;

[0044] The drainage tube 1 is connected to the upper end of the negative pressure ball 2 through a quick connector, and the quick connector can be further disassembled and replaced. The quick connector contains an anti-backflow valve to prevent liquid backflow;

[0045] The inner wall of the drainage tube 1 has a micro-texture design to reduce the adhesion of the liquid and improve the drainage efficiency;

[0046] Equipped with Bluetooth and Wi-Fi functions, it can be remotely monitored and controlled through mobile phone APP or hospital management system to achieve intelligent interconnection;

[0047] The part where the drainage tube 1 is connected to the negative pressure ball 2 is a telescopic rotating interface;

[0048] The end of the drainage tube 3 is equipped with a disposable liquid collection bag and a protective cover to prevent contact infection;

[0049] Also included is a battery module to ensure proper negative pressure functionality during power outages or patient transfers.

[0050] Preferably, the negative pressure sensing device 4 includes a negative pressure sensor 41 installed in the negative pressure ball 2 , and the negative pressure sensor 41 is used to detect the negative pressure value in the negative pressure ball 2 .

[0051] Preferably, the negative pressure sensing device 4 also includes a float sensor to detect the drainage volume of the drainage liquid in the negative pressure ball. When the drainage volume reaches half of the negative pressure ball, a prompt message will appear on the display 5 to remind medical staff that they can perform drainage treatment.

[0052] Preferably, the negative pressure control module 6 comprises: a negative pressure valve 61 installed between the drainage tube 1 and the negative pressure ball 2 , and a drain valve 62 installed between the drain tube 3 and the negative pressure ball 2 .

[0053] Preferably, the negative pressure control module 6 further comprises a control panel installed inside the display 5 for controlling the opening and closing states of the negative pressure valve 61 and the drain valve 62 .

[0054] Preferably, the negative pressure value is transmitted to the negative pressure control module 6 , and the specific negative pressure value is displayed on the display 5 .

[0055] Preferably, the negative pressure value is transmitted to the control board, and the control board makes a judgment based on the negative pressure value and controls the opening and closing degree of the negative pressure valve 61 .

[0056] Preferably, the negative pressure value is transmitted to the control panel for storage, the negative pressure value and changes are recorded, and can be viewed through the display 5, so that medical staff can monitor and track the wound healing status, and then judge the patient's wound status and make nursing decisions.

[0057] Preferably, a preset range of negative pressure values ​​can be set through the display 5 , and when the control panel determines that the negative pressure in the negative pressure ball 2 exceeds the preset range, the negative pressure valve 61 is controlled to be closed.

[0058] Preferably, when the negative pressure in the negative pressure ball 2 exceeds the preset range, an alarm message will appear on the display 5 and an alarm will sound.

[0059] Preferably, in this embodiment, negative pressure data is collected by a negative pressure sensor and transmitted to the control board. The patient's negative pressure data is analyzed by a machine learning algorithm to monitor and discover negative pressure trends and changes, predict possible complications, and promptly send alarm information to medical staff. It should be noted that in order to implement this prediction algorithm, it is necessary to combine real-time data analysis and historical data, and use machine learning technology to train the algorithm model. When the negative pressure sensor fails or errs, the machine learning algorithm detects the abnormality and transmits it to the control board to close the negative pressure valve 61, thereby preventing erroneous drainage in time.

[0060] Specifically, before starting the negative pressure drainage, the required preset range of negative pressure values ​​is set through the display 5 so that the negative pressure control module 6 can control the negative pressure state of the device.

[0061] Specifically, the negative pressure valve 61 opens and closes under the control of the negative pressure control module 6. When the negative pressure sensor 41 detects that the negative pressure value exceeds the preset range of the negative pressure value, the negative pressure valve 61 will automatically close to prevent the negative pressure from reaching the patient's wound from the drainage tube 1.

[0062] Specifically, when a large amount of waste liquid has been drained into the negative pressure ball 2 , the negative pressure valve 61 can be manually closed and the drain valve 62 can be opened to transfer the waste liquid from the negative pressure ball 2 through the drain pipe 3 .

[0063] Specifically, the negative pressure valve 61 and the drain valve 62 are one-way valves.

[0064] Preferably, the drainage tube 1 and the discharge tube 3 can be made of degradable biomaterials to reduce the impact on the environment. The degradable biomaterials can specifically be degradable plastics, such as PLA (polylactic acid) or PHB (polyhydroxyalkanoate). These materials can be degraded into water and carbon dioxide in the environment under certain conditions and have less impact on the environment. However, the manufacture of these pipes requires engineering treatment of the materials to ensure that they can withstand the corresponding negative pressure and chemical properties of the drainage fluid during use.

[0065] Preferably, solar panels or other renewable energy sources can be used as the energy source of the negative pressure drainage device to reduce dependence on traditional electricity and increase the mobility of the device. In the absence of traditional power sources, a stable power supply can be maintained to maintain the safe operation of the negative pressure drainage device. If solar panels are used as the energy source of the negative pressure drainage device, the solar panels can directly convert solar energy into electrical energy to supply the negative pressure drainage device. Under sufficient light conditions, the solar panels can provide stable energy for the equipment, reduce or eliminate the need for external power access, and can provide a backup power system to ensure the normal operation of the equipment at night or in low light conditions.

[0066] Based on the above scheme, as shown in the attached Figure 2 As shown, an air outlet valve 7 is also installed on the negative pressure ball 2 , and the air outlet valve 7 is installed on the air outlet valve interface 21 .

[0067] Preferably, the air outlet valve 7 is a one-way ball valve, which is used to control the gas in the negative pressure ball 2 to flow out, while preventing external gas and liquid from entering the negative pressure ball 2, which is conducive to forming negative pressure when squeezing the negative pressure ball 2.

[0068] Preferably, a check piece 8 is provided in the drainage tube 1 to prevent the drained liquid from flowing back into the drainage tube 1 .

[0069] Based on the above scheme, as shown in the attached Figure 3 As shown, the display 5 can be installed on the negative pressure ball 2 to reduce the distance between the negative pressure sensing device 4 and the display 5, making the entire device more compact and making it easier to observe the negative pressure value on the display 5.

[0070] Preferably, the display 5 can adopt a flexible soft material display screen, so that it can be bent into a consistent arc with the outer edge of the negative pressure ball 2, so as to better fit the outer edge of the negative pressure ball 2, effectively reducing the overall volume of the negative pressure drainage device, making it easier to fold and carry.

[0071] Based on the above scheme, as shown in the attached Figure 4 As shown, it is a display schematic diagram of the display 5, that is, the display unit of the display 5, which includes parameter information that needs to be understood during negative pressure drainage, provides a more accurate reference for medical staff, and ensures the health of patients and the progress of postoperative recovery. The display unit specifically includes:

[0072] The alarm information display area 51 is used to display alarm information, sensor failure information, etc. when the negative pressure value exceeds the set value;

[0073] The working parameter display area 52 is used to set the negative pressure value range, and display the current negative pressure value of the negative pressure drainage device, the set negative pressure value, etc.;

[0074] The working mode display area 53 is used to display the current working status, including drainage mode, discharge mode, etc.;

[0075] The negative pressure valve status display area 54 is used to display the opening and closing status of the negative pressure valve 61;

[0076] The drain valve status display area 55 is used to display the open and closed status of the drain valve 62;

[0077] The air outlet valve status display area 56 is used to display the opening and closing status of the air outlet valve 7.

[0078] Specifically, when there is no human operation, the display unit displays various parameters and status information in a scrolling cycle. Only when the staff touches the display unit of the display 5 will all the information be displayed.

[0079] Preferably, the display 5 has an internal structure in addition to the display unit, including:

[0080] A control panel, used to control the negative pressure valve 61 according to the range of negative pressure value set by the user, used to control the drain valve 62, and used to control the content displayed on the display unit;

[0081] The command communication unit is used to transmit the commands issued by the control board to specific components.

[0082] Based on the above scheme, as shown in the attached Figure 5 FIG. 1 is an internal structure diagram of a negative pressure valve 61, which is a hydraulically controlled one-way valve, including:

[0083] Push rod 611, hydraulic control valve core 612, control port 613, opening 1 614, opening 2 615; the control port 613 controls the size of the cavity connected to the port, and the cavity is provided with control liquid, and the pressure and flow direction of the control oil are adjusted through the control port 613; when the control oil is not passed into the control port 613, the push rod 611 is pressed against the inner wall of the left end under the action of the spring of the hydraulic control valve core 612, and the opening 2 615 is blocked and closed by the hydraulic control valve core 612, and the opening 1 614 is opened and connected to the drainage tube 1. Under the action of the drainage liquid, the spring of the hydraulic control valve core 612 is compressed, and the opening 2 615 is opened and connected to the negative pressure ball 2, so that the drainage liquid circulates and drains the drainage liquid from the patient's wound into the negative pressure ball 2; when the control oil is passed into the control port 613, the position of the hydraulic control valve core 612 can be controlled by the flow speed of the pressure of the control oil, so as to control the opening and closing degree of the opening 2 615, and control the drainage speed and drainage amount.

[0084] Specifically, the use of the hydraulically controlled one-way valve can provide more precise flow control and ensure the stability of the system. When selecting a specific model, it is selected according to the specific application scenario of the negative pressure drainage device. The specific factors to be considered include:

[0085] Flow requirements: Based on the specific flow requirements of the system, including the flow of drainage liquid and the gas flow required in the negative pressure drainage system, the maximum and minimum flow requirements under different circumstances need to be considered;

[0086] Working pressure: Understand the working pressure required by the negative pressure drainage system at different stages, and select the rated working pressure range of the hydraulically controlled one-way valve according to these pressure requirements;

[0087] Medium requirements: Consider the liquid medium in the drainage system, select materials and sealing materials that are compatible with the medium, and hydraulically controlled one-way valves that are corrosion-resistant and wear-resistant.

[0088] Based on the above scheme, as shown in the attached Figure 6 As shown, another internal structure diagram of the negative pressure valve 61 is a cone valve type straight-through one-way valve, including a one-way valve core 616, the right side of the one-way valve is a liquid inlet, and the left side is a liquid outlet. When the negative pressure valve 61 is opened, the drainage liquid enters from the right side of the one-way valve under the action of negative pressure, compresses the spring of the one-way valve core 616, and the one-way valve is opened, and the drainage liquid flows out from the left side of the one-way valve into the negative pressure ball 2.

[0089] In this embodiment, a negative pressure drainage device is proposed that can display the negative pressure value and the negative pressure drainage status in real time. By setting a display to display drainage parameters and other information, setting a drainage value limit, and setting an alarm device, the negative pressure drainage process is precisely controlled to reduce the workload of medical staff and prevent improper control of the force when squeezing the negative pressure ball to generate negative pressure, which may cause harm to the patient.

[0090] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
