[0002] In the prior art, minimally invasive dilation and drainage kits are commonly used in the medical field, especially in cases where fluids such as pus, blood or other body fluids need to be drained. These kits allow doctors to drain body fluids out of the body through small incisions without performing large incision surgery. However, existing drainage kits usually lack the function of measuring pressure, which is very important in certain medical situations. For example, in surgical operations, too high or too low pressure may have serious consequences for patients.
[0003] Therefore, existing drainage kits fail to provide the ability to monitor pressure in real time while providing drainage function, which limits their scope of application and effectiveness. In some cases, doctors may need to use additional equipment to monitor pressure, which not only increases the complexity of the operation but also increases the risk to patients. In addition, drainage kits without manometry function are unable to provide important information about pressure changes during drainage, which may have a negative impact on the patient's recovery and treatment effect.
[0004] Therefore, it is very necessary to develop a minimally invasive dilation and drainage kit with a manometry function, which can monitor the pressure during drainage, thereby improving the safety and efficiency of the operation and providing doctors with more information to optimize the treatment plan.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example
[0023] like Figure 1-Figure 3 As shown, the utility model provides a minimally invasive dilation and drainage kit.
[0024] It includes a drainage tube sleeve 1 and a joint 2, wherein the joint 2 is arranged at one end of the drainage tube sleeve 1, the drainage tube sleeve 1 is hollow, a drainage tube is arranged inside the drainage tube sleeve 1, the joint 2 is connected with the drainage tube sleeve 1, an inner sleeve is arranged on the joint 2, the inner sleeve includes a first inner sleeve 3 and a second inner sleeve 4, the first inner sleeve 3 and the second inner sleeve 4 are respectively arranged on both sides of the joint 2, the first inner sleeve 3 and the second inner sleeve 4 are both connected with the drainage tube sleeve 1, a first through hole 5 is opened on the side wall of one end of the drainage tube sleeve 1 away from the joint 2, a second through hole 6 is opened on the side wall of the joint 2, the first through hole 5 is arranged to penetrate along the length direction of the drainage tube sleeve 1, and is connected with the second through hole 6;
[0025] The first through hole 5 and the second through hole 6 are both configured as pressure measuring holes;
[0026] The drainage tube in the drainage tube sleeve 1 can be slidably adjusted along the length direction of the drainage tube sleeve 1 to meet the drainage requirements of different lengths. An internal thread is arranged inside one end of the joint 2, and an external thread is arranged at one end of the drainage tube sleeve 1. The joint 2 and the drainage tube sleeve 1 are fixedly connected via the internal thread and the external thread to prevent them from loosening.
[0027] A sealing ring is provided between the drainage tube sleeve 1 and the joint 2 to ensure that liquid does not leak from the joint 2 during the drainage process.
[0028] The cross-sections of the first through hole 5 and the second through hole 6 are both set to a circular structure, or the cross-sections of the first through hole 5 and the second through hole 6 are both set to a rectangular structure. In this embodiment, the cross-sections of the first through hole 5 and the second through hole 6 are both set to a circular structure, but are not limited thereto and can be set according to actual needs;
[0029] During use of the present application, the doctor first selects a drainage tube sleeve 1 of a suitable size according to the specific conditions of the patient, docks the external thread of the drainage tube sleeve 1 with the internal thread of the connector 2, tightens to fix the connection, adjusts the position of the drainage tube in the drainage tube sleeve 1 so that its length adapts to the depth of the drainage site, and after local anesthesia, inserts the drainage tube into the drainage site in the patient's body, and the body fluid flows to the connector 2 through the drainage tube;
[0030] During the drainage process, the pressure during the drainage process is monitored in real time by a pressure sensor connected to the first through hole 5 and the second through hole 6. The doctor can read the pressure data through the monitoring device to ensure that the pressure during the drainage process remains within a safe range;
[0031] The first through hole 5 and the second through hole 6 serve as pressure measuring holes, which are connected to a pressure sensor to transmit pressure data in real time. The doctor can adjust the drainage strategy according to the pressure data, such as adjusting the position of the drainage tube or changing the drainage speed.
[0032] Assume that a patient needs drainage after lithotripsy. The doctor selects a suitable minimally invasive dilatation drainage kit and follows the above steps. During the drainage process, the doctor monitors the patient's drainage pressure in real time through the pressure sensor connected to the first through hole 5 and the second through hole 6. If the pressure is too high, it indicates that there may be a blockage, and the doctor will adjust the position of the drainage tube; if the pressure is too low, it may be necessary to increase the drainage volume. Through real-time monitoring, the doctor can ensure that the drainage process proceeds smoothly and avoid complications caused by abnormal pressure, thereby ensuring the safety of the patient.
[0033] During the drainage process, the pressure sensor achieves real-time monitoring in the following ways:
[0034] Sensor installation: This is achieved by connecting the sensor to the second through hole 6 using a pipe.
[0035] Pressure Sensing: When body fluid flows through the drainage tube, it generates pressure at the pressure tap. This pressure is sensed by the sensor and converted into an electrical signal depending on the type of sensor (such as piezoelectric, piezoresistive or capacitive).
[0036] Signal conversion: The mechanical structure inside the sensor will deform due to pressure changes. This deformation will cause changes in resistance, capacitance or voltage, thereby generating an electrical signal proportional to the pressure.
[0037] Signal transmission: The generated electrical signal is transmitted to the monitoring system via wires or wirelessly. In some advanced systems, IoT technology may be used for data transmission.
[0038] Data processing and display: After the monitoring system receives the signal, it will process the data and display the pressure reading in real time on the monitoring interface. This allows medical personnel to observe pressure changes in real time.
[0039] Early warning and feedback: If the monitored pressure exceeds the safe range, the system will issue an early warning signal to prompt medical personnel to take corresponding measures
[0040] In this way, the pressure sensor can provide medical staff with important information about pressure changes during the drainage process, helping them make better clinical decisions. This real-time monitoring technology is essential to ensure surgical safety and improve treatment outcomes.
[0041] In the minimally invasive dilatation and drainage kit of the present application, the first inner cannula 3 and the second inner cannula 4 have the following functions:
[0042] Providing a bidirectional channel: The first inner sleeve 3 and the second inner sleeve 4 are respectively arranged on both sides of the connector 2, which are connected to the drainage sleeve 1 to form two independent channels. This design allows body fluids to be drained through one channel, while the other channel can be used for other operations such as pressure measurement or drug injection.
[0043] Increased flexibility and functionality: By providing two inner cannulas, medical personnel can perform multiple operations simultaneously, such as draining fluid while monitoring pressure, or administering medication during the drainage process, which increases the flexibility and functionality of the kit.
[0044] Maintaining the stability of the drainage tube sleeve 1: The provision of the inner sleeve also helps to maintain the structural stability of the drainage tube sleeve 1, ensuring that the drainage tube sleeve 1 will not be deformed or displaced due to external pressure or operation during the drainage process.
[0045] In general, the design of the first inner cannula 3 and the second inner cannula 4 makes the drainage kit more versatile and adaptable, meeting the diverse clinical needs for minimally invasive drainage devices. This design improves the efficiency and safety of the operation and provides patients with a better treatment experience.
[0046] In the minimally invasive dilation and drainage kit of this application, the role of the scale line is:
[0047] Accurate measurement: The graduation lines allow medical personnel to accurately measure the depth of the drainage tube sheath 1 inserted into the body, ensuring that the drainage tube sheath 1 can accurately reach the target drainage area.
[0048] Monitoring drainage volume: The scale allows doctors to monitor and record the amount of body fluid during drainage, which is very important for evaluating the patient's recovery progress and drainage effectiveness.
[0049] Adjusting the Position: If the position of the drainage tube sleeve 1 needs to be adjusted, the scale lines provide a visual reference to ensure that the drainage tube sleeve 1 can be correctly repositioned.
[0050] Operational guidance: The graduation lines can also serve as guidance for medical personnel when operating the drainage kit, helping them to more accurately control the use of the drainage tube sleeve 1.
[0051] In conclusion, the graduation marks are an important feature in the design of drainage kits, which improves the precision and safety of the procedure while providing convenience and efficiency for medical personnel.
[0052] The present application can improve surgical safety. By real-time monitoring of the pressure during the drainage process, medical personnel can adjust the drainage strategy in a timely manner to avoid complications caused by abnormal pressure, thereby ensuring the safety of patients and improving surgical efficiency. The drainage tube in the drainage tube sleeve 1 can be slid and adjusted along the length direction to adapt to drainage requirements of different lengths, reducing operation time and patient discomfort, and further enhancing functionality: the design of the inner sleeve provides a two-way channel, so that the kit can perform drainage and other operations at the same time, such as pressure measurement or drug injection, thereby improving the versatility of the kit.
[0053] The utility model is easy to operate: the design of the scale line enables medical personnel to accurately control the position of the drainage tube sleeve 1, thus simplifying the operation process.
[0054] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
