Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an intelligent drainage tube fixing device with anti-inflammatory treatment effects. Background Art

[0002] After clinical surgery, it is necessary to drain pus, blood, bile, secretions, inflammatory exudates, etc. in the patient's tissues or body cavities out of the body to prevent accumulation in the body cavity, secondary compression symptoms, infection or tissue damage. Usually, the purpose of draining the body fluid in the patient is achieved by implanting a drainage tube into the patient's body. Since the patient needs to turn over or move appropriately, it is extremely easy to pull the drainage tube, and the phenomenon that the drainage tube easily protrudes outwards is likely to occur, affecting the drainage effect, and at the same time increasing the probability of wound infection in the patient. Currently, clinically, silk threads are mostly used to tie and ligate around the tube wall of the drainage tube and then sutured on the skin surface. Due to the different materials of the drainage tube and the lack of a fixing device in the vertical outlet direction of the drainage tube on the skin, it is easy to cause the failure of silk thread fixation, resulting in the outward movement or even protrusion of the drainage tube perpendicular to the skin direction, thus resulting in the phenomena of unsmooth drainage, wound bleeding and wound infection. In severe cases, it may even endanger the patient's life safety. Therefore, the fixation of the drainage tube and the prevention of wound infection and inflammation are important issues in the postoperative care of the drainage tube. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects in the prior art, such as poor fixing effect of the drainage tube, easy detachment of the drainage tube, troublesome operation and easy infection and inflammation of the wound surface, and provide an intelligent drainage tube fixing device with good fixing effect, easy operation and anti-inflammatory and treatment effects.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an intelligent drainage tube fixing device with anti-inflammatory treatment effects, which is characterized in that: it includes a fixing tube and a main body with a circular hole in the center.

[0005] Further, a plurality of first protrusions are respectively arranged on the inner and outer sides of the fixing tube.

[0006] Further, the main body includes: a circular circuit board, a micro control unit arranged on the circular circuit board, a temperature sensor, a blood oxygen / heart rate sensor, an ultraviolet LED lamp, an infrared LED lamp, a working indicator lamp, a communication module and a power management module for supplying power to each module in the fixing device.

[0007] The temperature sensor is used to collect the temperature on the surface of the patient's wound.

[0008] The blood oxygen / heart rate sensor is used to collect the blood oxygen and heart rate on the surface of the patient's wound.

[0009] The micro control unit is used to control the on / off of the ultraviolet LED lamp and the infrared LED lamp, and transmits the temperature, blood oxygen and heart rate information of the patient's wound surface monitored by the temperature sensor and the blood oxygen / heart rate sensor to an external communication device through a communication module. If a certain monitoring parameter exceeds a pre-set danger threshold, an alarm instruction is sent to the working indicator light.

[0010] Further, the communication module adopts WIFI or Bluetooth wireless network communication technology, and the external communication device is a remote management center or a mobile phone app.

[0011] Further, the ultraviolet LED lamp and the infrared LED lamp are arranged in an alternating circular array on the circular circuit board 210.

[0012] Further, a USB Type-C charging interface or a DC charging interface is also provided on the circular circuit board.

[0013] Further, ventilation holes are provided on the fixing ring.

[0017] The beneficial effects of an intelligent drainage tube fixing device with anti-inflammatory treatment efficacy according to the present invention are as follows:

[0018] 1. For the present invention, only the main body needs to be sleeved on the fixing tube and slightly pushed to the bottom of the fixing ring after sterilization treatment, so that the silica gel sleeve on the outer surface of the main body is tightly fitted with the first protrusion on the outer side of the fixing tube.

[0034] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0035] Embodiment 1

[0036] As Figures 1-6 shown in Embodiment 1 of an intelligent drainage tube fixing device with anti-inflammatory treatment efficacy of the present invention, it includes a fixed tube 1 and a main body 2 with a circular hole in the center. The bottom end of the fixed tube 1 is fixed with a fixed ring 3 with a concave center. The fixed ring 3 is provided with ventilation holes 32, which helps to maintain the air permeability of the patient's skin. The outer periphery of the fixed ring 3 is provided with a first base glue 31. The drainage tube 4 passes through the fixed ring 3 and the fixed tube 1 in sequence and is connected with the fixed tube 1 by interference fit. Both the inner wall and the outer wall of the fixed tube 1 are provided with a plurality of first protrusions 11. The height of the first protrusions 11 is 0.1 mm -

[0037] 0.5 mm. The first protrusions 11 can be semi-cylindrical protrusions, strip-shaped protrusions or dot-shaped protrusions, etc. The drainage tube 4 is generally made of materials such as silicone rubber or polyurethane. According to the elastic characteristics of silicone rubber or polyurethane, the drainage tube 4 can be clamped in the fixed tube 1 by interference fit, and then the first base glue 31 at the bottom of the fixed ring 3 is attached to the patient's skin to achieve the purpose of fixing the drainage tube 4 in the direction perpendicular to the skin. In order to prevent the fixed tube 1 from pressing the patient's wound surface, the fixed ring 3 is set to have a concave center, and the fixed tube 1 is a disposable consumable. The fixed ring 3 is made of medical polymer materials, and the medical polymer materials are polycarbonate or polypropylene. In this embodiment, the fixed tube 1 is a 90° bent tube. When the fixed tube 1 is a 90° bent tube, in order to facilitate the fixed tube 1 to pass through the drainage tube 4, the inner wall of the fixed tube 1 may not be provided with the first protrusions 11.

[0038] As Figure 1 and Figure 2As shown in the figure, two sets of main units 2 are sleeved on the bottom of the fixed tube 1. The main unit 2 is encapsulated by a plastic box 6, and a silica gel sleeve 5 is wrapped around the plastic box 6. The outer surface of the main unit 2 is wrapped with the silica gel sleeve 5. The silica gel sleeve 5 is closely fitted with the fixed tube 1, and a second bottom glue 51 is provided at the bottom of the silica gel sleeve 5. The plastic box 6 includes an upper cover and a lower cover. The upper cover is made of ABS plastic or polycarbonate material, and the lower cover is made of polycarbonate or polymethyl methacrylate material. Preferably, the first bottom glue 31 and the second bottom glue 51 are transparent hydrogels. The main unit 2 is encapsulated by the plastic box 6, and then the plastic box 6 is wrapped with the silica gel sleeve 5, which plays a role of sealing and waterproofing, protecting the circuit in the main unit 2 from being dry and corroded. The main unit 2 wrapped with silica gel has good sealing performance and can be reused after disinfection, thus reducing the use cost.

[0039] See Figure 4 , the main unit 2 includes: an annular circuit board 210, a micro control unit 21, a temperature sensor 22, a blood oxygen / heart rate sensor 23, an ultraviolet LED lamp 24, an infrared LED lamp 25, a working indicator lamp 26, a communication module 27, and a power management module 28 arranged on the annular circuit board 210. During use, only need to sleeve the main unit 2 on the fixed tube 1 and apply a little force to push it to the bottom of the fixed tube 1 after sterilization treatment, so that the silica gel sleeve 5 on the outer surface of the main unit 2 is closely fitted with the first protrusion 11 on the outside of the fixed tube 1. Then, sleeve the fixing ring 3 on the drainage tube 4, so that the drainage tube 4 is clamped on the fixed tube 1 through interference fit. Turn on the switch of the main unit 2 to start working. The operation is simple, convenient and time-saving. The structure of separating the main unit 2 from the fixed tube 1 helps the doctor to quickly fix the drainage tube 4.

[0040] The temperature sensor 22 is used to collect the temperature on the surface of the patient's wound. The measurement accuracy of the temperature sensor 22 is ±0.1°C, and the repeatability is 0.1°C. For example, the MEAS non-contact infrared temperature sensor 22TS318-11C55 in the United States. Preferably, the micro control unit 21 issues an instruction for the temperature sensor 22 to work every five minutes at regular intervals. Then, the temperature sensor 22 starts to monitor the temperature on the surface of the patient's wound. If the temperature parameter exceeds the dangerous threshold preset for the micro control unit 21, the micro control unit 21 issues an alarm instruction to display a red light to the working indicator lamp 26.

[0041] The blood oxygen / heart rate sensor 23 is used to collect the blood oxygen and heart rate on the surface of the patient's wound. The blood oxygen / heart rate sensor 23 includes a photodiode and three green LEDs with an emission wavelength of 530 nm. It monitors the heart rate by measuring the amount of blood flowing through the blood vessels. Its working principle is to irradiate the skin surface with light. Blood and surrounding tissues absorb different amounts of light, and the unabsorbed light is reflected back to the detector. For example, the OSRAM blood oxygen / heart rate infrared optical sensor from Germany. Preferably, after the UV LED lamp 24 and the infrared LED lamp 25 stop working for half an hour, the micro-control unit 21 issues an instruction to make the blood oxygen / heart rate sensor 23 work at regular intervals of 10 minutes. The blood oxygen / heart rate sensor 23 monitors the patient's blood oxygen and heart rate information every 10 minutes. If any one of the blood oxygen or heart rate parameters exceeds the dangerous threshold preset for the micro-control unit 21, the micro-control unit 21 issues an alarm instruction to make the working indicator light 26 display a red light. When the UV LED lamp 24 and the infrared LED lamp 25 are working, the blood oxygen / heart rate sensor 23 does not work.

[0042] As Figure 5 and Figure 6 shown, the micro-control unit 21 is used to control the on / off of the UV LED lamp 24 and the infrared LED lamp 25. The UV LED lamp 24 and the infrared LED lamp 25 are arranged in an alternating circular array on the circular circuit board 210. The UV LED lamp 24 and the infrared LED lamp 25 work alternately in a cycle, producing a superimposed effect on the wound regeneration, which is beneficial to the patient's rapid recovery. The optimal distance between the UV LED lamp 24 and the infrared LED lamp 25 from the skin surface is 2 mm - 5 mm. Preferably, the micro-control unit 21 controls the UV LED lamp 24 to work for 15 - 30 minutes and stop for 2 hours. When the UV LED lamp 24 stops working, the micro-control unit 21 controls the infrared LED lamp 25 to work for 10 - 30 minutes and stop for 2 hours. The light irradiated by the UV LED lamp 24 and the infrared LED lamp 25 is easily absorbed by the skin. The thermal effect of the infrared LED lamp 25 irradiation dilates the arterioles and capillaries, has an anti-inflammatory and detumescence effect, improves blood circulation, and promotes wound healing.

[0043] The communication module 27 is used to transmit various monitoring data to the external communication device 29. The communication module 27 adopts WIFI or Bluetooth wireless network communication technology. The external communication device 29 is a remote management center or a mobile APP. The ID address of each host 2 is unique. The micro-control unit 21 transmits the monitored temperature parameter, blood oxygen parameter, and heart rate parameter on the surface of the patient's wound to the remote management center or the mobile APP through WIFI or Bluetooth, which is convenient for doctors to observe the patient's wound situation at any time and take measures in a timely manner when necessary.

[0044] The microcontroller unit 21 transmits the temperature, blood oxygen, and heart rate information of the patient's wound surface, which are real-time monitored by the temperature sensor 22 and the blood oxygen / heart rate sensor 23, to the external communication device 29 through the communication module 27. If a monitoring parameter exceeds a pre-set danger threshold, an alarm instruction is sent to the working indicator light 26.

[0045] The power management module 28 is used to supply power to each module in the fixing device. The power management module 28 supplies power to each module in the fixing device through a lithium battery or an external power supply. A USB Type-C charging interface or a DC charging interface is also provided on the circular circuit board 210. The fixing device can supply power to each module in the host 2 through a lithium battery, or can supply power to each module in the host 2 through an external power supply via the USB Typc-C interface or the DC charging interface.

[0046] The specific installation method and working process of the fixing device are as follows: First, sterilize the fixing tube 1 and the fixing ring 3, then align the round hole in the middle of the bottom of the host 2 with the top of the fixing tube 1, move it along its axis to the first protrusion 11 outside the fixing tube 1, and then slightly apply force to push the host 2 to the bottom of the fixing tube 1, so that the silica gel sleeve 5 on the outer surface of the host 2 is tightly fitted with the first protrusion 11 on the outside of the fixing tube 1. Then, sleeve the fixing tube 1 and the fixing ring 3 on the drainage tube 4, so that the drainage tube 4 is clamped on the fixing tube 1 through interference fit. Finally, attach the first bottom glue 31 at the bottom of the fixing ring 3 and the second bottom glue 51 at the bottom of the silica gel sleeve 5 to the patient's skin. Turn on the power of the host 2, and the microcontroller unit 21 controls the ultraviolet LED lamp 24 and the infrared LED lamp 25 to work alternately in a cycle. The microcontroller unit 21 controls the temperature sensor 22 to regularly monitor the temperature of the patient's wound surface. If the temperature parameter exceeds the pre-set danger threshold for the microcontroller unit 21, the microcontroller unit 21 sends an alarm instruction to the working indicator light 26 to display a red light; when the ultraviolet LED lamp 24 and the infrared LED lamp 25 stop working, the microcontroller unit 21 controls the blood oxygen / heart rate sensor 23 to regularly monitor the blood oxygen and heart rate information of the patient. If either the blood oxygen or heart rate parameter exceeds the pre-set danger threshold for the microcontroller unit 21, the microcontroller unit 21 sends an alarm instruction to the working indicator light 26 to display a red light; the ID address of each host 2 is unique. The microcontroller unit 21 transmits the monitored temperature parameter, blood oxygen parameter, and heart rate parameter of the patient's wound surface to the remote management center or the mobile phone APP through WIFI or Bluetooth, which is convenient for doctors to observe the situation of the patient's wound at any time and take measures in time if necessary. The structure of separating the host 2 and the fixing tube 1 helps doctors quickly fix the drainage tube 4. The fixing tube 1 is a disposable consumable, and the host 2 wrapped with silica gel has good sealing performance and can be reused after disinfection, thus reducing the use cost.

[0047] Embodiment 2

[0048] During clinical surgery, according to the doctor's needs, in order to better fix the drainage tube 4, the fixing tube 1 can also be a bent tube, and the rest is the same as in Embodiment 1.

[0049] See Figure 7 , in this embodiment, the fixing tube 1 is a 135° bent tube.

[0050] Embodiment 3

[0051] As Figure 8 and Figure 9 shown, during surgery, according to the different diameters of the drainage tube 4, a fixing frame 33 adapted to the diameter of the drainage tube 4 is provided at the center of the fixing tube 1 or the fixing ring 3. A plurality of second protrusions 331 are provided on the inner side of the fixing frame 33. The height of the second protrusion 331 is 0.1 mm - 0.5 mm. The second protrusion 331 can be a semi-cylindrical protrusion, a strip-shaped protrusion or a dot-shaped protrusion, etc. In this embodiment, the fixing tube 1 is a straight tube, and the fixing ring 3 and the fixing frame 33 are made of a medical polymer material. The medical polymer material is polycarbonate or polypropylene. In order to better fix the drainage tube 4, a plurality of second protrusions 331 are provided on the inner side of the fixing frame 33.

[0052] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
