Description

Technical Field

[0001] The present invention relates to the technical field of wound auxiliary treatment equipment, and in particular to an intelligent wound auxiliary rehabilitation device. Background Art

[0002] Wounds are a common condition after surgery, such as obstructive small bowel or colostomy, permanent stoma or preventive stoma after colorectal cancer surgery, etc. During surgical treatment, the intestine needs to be separated and one end of the intestine needs to be led to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening. In order to prevent excessive exudate from the opening, which may cause infection in the wound and affect the patient's recovery, the exudate at the wound needs to be treated in time.

[0003] There are two main methods for wound treatment: 1. When there is a small amount of exudate from the wound, dressings are usually placed on the wound surface to absorb the exudate, but the exudate from the wound cannot be monitored and the dressings need to be changed frequently. Since the dressings need to be in contact with the wound, frequent changes of dressings can easily cause wound infection, and the production cost of the dressings is also high.

[0004] 2. When there is a large amount of exudate from the wound, a closed drainage tube can be used to drain the exudate. The closed drainage tube usually uses a scalp needle tube with the needle removed to connect to a 10ml syringe. The head of the scalp needle tube is fixed to the wound and fixed with medical tape, and then the syringe rod is manually pulled to generate negative pressure. Under the action of negative pressure, the exudate from the wound is sucked into the syringe. However, this device cannot work for a long time. When the amount of exudate is large, the syringe needs to be replaced frequently because the capacity of the syringe is too small, and the negative pressure suction generated by the syringe is not large enough, resulting in a very slow suction speed, which affects wound healing. When there is no subsequent exudate flowing out of the wound, if the negative pressure suction is always applied to the wound and the wound exudate cannot be checked in time, it is easy to cause damage to the wound. Summary of the invention

[0005] The purpose of the present invention is to solve one of the technical problems in the related art to a certain extent at least.

DETAILED DESCRIPTION

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1 See also Figure 1 , 3 -4, the present invention provides an intelligent wound auxiliary rehabilitation device, including a liquid suction pump 1, a liquid suction tube 2, a liquid storage container 3, an exudate collection unit 4, a start-stop switch 5, a power supply device 6, a control unit 7, a display unit 16 and a warning unit 25.

[0027] The first end of the pipette 2 is fixed to the wound, and the second end of the pipette 2 is connected to the liquid pump 1 through the liquid storage container 3. The liquid storage container 3 is provided with two connectors, one of which is connected to the suction port of the liquid pump 1 through the liquid guide tube, and the other connector is connected to the second end of the pipette 2.

[0028] The pipette 2 is one of a chest drainage tube, a gastric tube, an intestinal tube, a central venous catheter, and a scalp needle. Different types of pipettes 2 can be used according to the size or location of the wound to meet the needs of different patients.

[0029] like Figure 1 , 2 As shown, as one of the embodiments, the liquid pipette 2 includes a flexible tube 21 and a flexible positioning strip 22 arranged on the outer side wall of the flexible tube 21. The front end of the flexible tube 21 and the flexible positioning strip 22 form the first end of the liquid pipette 2, and the rear end of the flexible tube 21 forms the second end of the liquid pipette 2. The flexible tube 21 is provided with a liquid suction channel 21a for the circulation of exudate, and a plurality of equipment lumens 21b located outside the liquid suction channel 21a. The flexible positioning strip 22 is provided with a drainage groove 22a extending to communicate with the liquid suction channel 21a. Among them, the side wall of the flexible tube 21 is also provided with a plurality of drainage holes 21c connected to the liquid suction channel 21a. The drainage holes 21c are located on the outer side of the flexible positioning strip 22 away from the drainage groove 22a to prevent the liquid suction effect from being affected by the blockage of the front end of the liquid suction channel 21a. The wound exudate can enter the liquid suction channel 21a from the drainage holes 21c.

[0030] Align the front end of the flexible tube 21 with the wound, fit the side of the flexible positioning strip 22 with the drainage groove 22a to the wound surface, and then fix the flexible positioning strip 22 and the front end of the flexible tube 21 with a dressing, so that the wound exudate is guided from the drainage groove 22a to the suction channel 21a, and part of the exudate exposed from the drainage groove 22a enters the suction channel 21a from the drainage hole 21c. By setting the flexible positioning strip 22 on the flexible tube 21, effective positioning can prevent the suction tube 2 from shifting relative to the wound due to the patient's activities, and try to avoid leakage of exudate to contaminate clothing and affect the exudate suction effect.

[0031] In this embodiment, two flexible positioning strips 22 are relatively arranged on the outer side wall of the first end of the flexible tube 21, and the two flexible positioning strips 22 are connected to the outer edge of the fixed end of the flexible tube 21. The flexible positioning strips 22 and the flexible tube 21 are integrally formed to improve the structural strength of the pipette 2 itself.

[0032] like Figure 2-4 6, the power supply device 6 is electrically connected to the liquid pump 1 through the start-stop switch 5, the exudate collection unit 4 is electrically connected to the power supply device 6, and the exudate collection unit 4, the start-stop switch 5, the power supply device 6, the display unit 16 and the warning unit 25 are electrically connected to the control unit 7 respectively. The warning unit 25 includes an LED indicator and a buzzer. When an abnormal situation occurs, it issues alarms and light prompts and other warning information, which can effectively protect the health of the patient, and the warning information is displayed through the display unit 16. The display unit 16 is electrically connected to the control unit 7 through the interface J2.

[0033] The exudate collection unit 4 is installed on the first end of the suction tube 2. Specifically, the exudate collection unit 4 is installed at the front end of the suction channel 21a and is set in one of the equipment lumens 21b, and is used to collect the exudate state at the wound. The control unit 7 is used to send a control signal to the start-stop switch 5 according to the received exudate state; the start-stop switch 5 is used to control the start-stop state of the suction pump 1 according to the control signal.

[0034] The liquid pump 1 is an electric air pump, which uses variable frequency speed regulation and PWM control to control the speed of the electric air pump, and the exudate collection unit 4 is a capacitive pressure sensor. When the wound is exuding, the capacitance will change. When the control unit 7 receives the capacitance change, the start-stop switch 5 is automatically started, the liquid pump 1 is in working state, and the liquid pump 1 operates according to the preset input voltage, and the exudate at the wound is sucked from the suction tube 2 into the liquid storage container 3; when the wound stops exuding, the start-stop switch 5 is turned off, and the liquid pump 1 is turned off.

[0035] The preset input voltage can be set according to actual needs, so as to smoothly suck out the exudate and avoid excessive suction force causing damage to the wound. If the exudate to be sucked is relatively viscous, the suction force can be appropriately increased. In this embodiment, the preset input voltage is 1V, and by controlling the input voltage of the liquid pump 1, its rotation speed is controlled to adjust the negative pressure.

[0036] The preset input voltage can also change according to the capacitance collected by the exudate collection unit 4, so as to adapt to the specific exudate situation. The preset input voltage is Uinitial, Uinitial = a*C, where a is the proportional coefficient, C is the capacitance value currently collected by the capacitive pressure sensor, and a=3*10^-3.

[0037] The intelligent wound auxiliary rehabilitation device also includes a temperature collection unit 29 electrically connected to the liquid pump 1 and the control unit 7. It is used to collect temperature information of the liquid pump 1 in real time. When the current temperature of the liquid pump 1 exceeds the set temperature threshold, the control unit 7 determines that an abnormal situation has occurred and issues a high temperature alarm through the warning unit 25 to prevent the motor in the liquid pump 1 from overheating and causing failure due to long-term operation.

[0038] The start-stop switch 5 adopts an analog switch U5, and the automatic opening and closing of the start-stop switch 5 is realized by configuring the IO high and low levels of the control unit 7, and its switch state is displayed through the display unit 16.

[0039] like Figure 2 , 4As shown, an image acquisition unit 15 electrically connected to the control unit 7 is also provided on the first end of the pipette 2. The image acquisition unit 15 is installed in another device lumen 21b and is used to collect image information of the wound in real time. The image acquisition unit 15 uses a micro camera and displays the current wound image information through the display unit 16, so that medical staff can view the exudate and recovery of the wound in real time.

[0040] like Figure 1 , 4 As shown, the intelligent wound auxiliary rehabilitation device also includes a liquid level acquisition unit 8 electrically connected to the control unit 7. The liquid level acquisition unit 8 is installed on the liquid storage container 3 and is used to collect the liquid level of the exudate absorbed in the liquid storage container 3 in real time, so as to further calculate the amount of body fluid absorbed by the liquid storage container 3 within a set time (i.e., calculate the liquid level increase rate). The set time can be set as needed. Within a set time, by obtaining the body fluid level at the current moment and the body fluid level at the previous moment, the liquid level increase rate for the set time is calculated.

[0041] The liquid level acquisition unit 8 is a capacitive water level sensor, which uses a TM601 capacitive sensing chip, which is installed on the outer wall of the liquid storage container 3, and uses a non-contact method to collect the capacitance analog quantity corresponding to the liquid level in the liquid storage container 3. The seepage collection unit 4 is electrically connected to the liquid level acquisition unit 8, and is electrically connected to the third power supply module 20 and the control unit 7 through a digital converter 14, so as to convert the capacitance analog quantity into a capacitance digital quantity for the control unit 7 to calculate.

[0042] When the control unit 7 detects that the body fluid in the liquid storage container 3 exceeds the first set liquid level, the control unit 7 determines that an abnormal situation has occurred and issues a liquid level warning through the warning unit 25. The first set liquid level is set to 80% of the total liquid level of the liquid storage container 3. When the body fluid level exceeds 80%, the buzzer sounds an alarm to remind that the liquid storage container 3 needs to be replaced.

[0043] When the control unit 7 detects that the body fluid in the liquid storage container 3 exceeds the second liquid level, the control unit 7 determines that an abnormal situation has occurred, issues a liquid level alarm through the alarm unit 25, and automatically shuts down the liquid pump 1 through the start-stop switch 5. The second set liquid level is 90% of the total liquid level of the liquid storage container 3. When the body fluid level exceeds 90%, it means that the alarm has not worked. At this time, the start-stop switch 5 is automatically closed to prevent the body fluid in the liquid storage container 3 from overflowing and causing surrounding pollution.

[0044] When the control unit 7 detects that the current liquid increase rate exceeds the set liquid increase rate, the control unit 7 determines that an abnormal situation has occurred and issues a liquid speed alarm through the alarm unit 25 to remind medical staff that the patient's wound exudates a lot and there may be an infection, which requires timely treatment, thereby effectively protecting the patient's life and health.

[0045] like Figure 3 , 5 -6, the power supply device 6 includes a first power module 9 and a second power module 10 which are electrically connected to each other, and the second power module 10 is electrically connected to the start-stop switch 5. The second power module 10 includes a second voltage conversion unit and a digital rheostat, and the second voltage conversion unit is electrically connected to the first power module 9 and the start-stop switch 5 respectively, and the digital rheostat U4 is electrically connected to the control unit 7 and the second voltage conversion unit respectively. The control unit 7 realizes that the output voltage of the second power module 10 is adjustable by controlling the resistance value of the digital rheostat U4 to change the input voltage of the liquid pump 1.

[0046] In order to facilitate medical staff to know the current negative pressure value, the intelligent wound auxiliary rehabilitation device also includes a first voltage acquisition unit 17, which is electrically connected to the liquid pump 1 and the control unit 7. The first voltage acquisition unit 17 is used to collect the input voltage at both ends of the liquid pump 1 in real time; the control unit 7 is used to obtain the current negative pressure value according to the collected input voltage.

[0047] Among them, the relationship between the input voltage and the current negative pressure value is obtained through testing, specifically by modifying the input voltage at both ends of the liquid pump 1, so that the negative pressure acquisition unit 19 installed on the liquid catheter and electrically connected to the second power supply module 10 and the control unit 7 respectively, reads the negative pressure value at this time, and obtains the corresponding relationship between the two. The control unit 7 calculates the negative pressure value at this time according to the collected input voltage and the corresponding relationship, and sends it to the display unit 16 for real-time and intuitive display. The current negative pressure value can also be collected in real time by the negative pressure acquisition unit 19 to calibrate the current input voltage.

[0048] The power supply device 6 further includes a battery charging management unit 11 and a rechargeable battery 12. The voltage output end of the battery charging management unit 11 is electrically connected to the first power module 9. The battery charging management unit 11 is electrically connected to the rechargeable battery 12 via the interface P6. The battery charging management unit 11 is electrically connected to an external power source via a charging interface 13. The power supply device 6 further includes a second voltage acquisition unit 24 for acquiring the voltage at both ends of the rechargeable battery 12. The second voltage acquisition unit 24 is electrically connected to the control unit 7 and the rechargeable battery 12, respectively, and obtains the battery power status at this time via the display unit 16, so as to facilitate timely charging.

[0049] The power supply device 6 also includes a third power module 20. The first power module 9 includes a first voltage conversion unit and a first variable resistor P4 which are electrically connected to each other. The voltage output end of the first voltage conversion unit is electrically connected to the second power module 10 and the third power module 20 through a power switch 23 (i.e., switch S1). The switch S1 controls whether the voltage is output normally to supply power to the subsequent circuit. The control unit 7, the start-stop switch 5, the seepage collection unit 4, and the liquid level collection unit 8 are electrically connected to the third power module 20, respectively. The first variable resistor P4 is used to manually adjust the resistance value. By controlling its resistance value, the output voltage of the first power module 9 is adjustable to change the input voltage of the second power module 10 and the third power module 20.

[0050] like Figure 5 As shown, when the charging interface 13 is connected to an external charger, it is powered by an AC power supply, the PMOS tube Q2 in the peripheral circuit of the battery charging management unit 11 is turned on, and the voltage VSS is directly powered by the external power supply VBUS. When no external charger is connected, the voltage VSS is powered by the rechargeable battery 12. When the battery charging management unit 11 is not in use, it enters a low-power standby mode to extend the service life of the rechargeable battery 12 and has better endurance. Multiple power supply methods make the device itself portable and the patient can get out of bed and move around at will. The scope of use is not restricted, which is conducive to the patient's recovery.

[0051] like Figure 4 , 6 As shown, the intelligent wound auxiliary rehabilitation device also includes a communication unit 18 and a storage unit electrically connected to the control unit 7. The communication unit 18 transmits information with external equipment to facilitate monitoring and management of the wound condition.

[0052] The storage unit is used to store physiological indicator data (e.g., time, exudate volume, etc.) and video data of wound conditions during treatment, which is convenient for medical staff to view and analyze later. The communication unit 18 uses an integrated Bluetooth module, which is electrically connected to the control unit 7 through the interface J3 to achieve wireless transmission, which is more suitable for the architecture of smart hospitals. All alarm information is sent to the mobile phone through the Bluetooth module to prevent the alarm from being ignored and facilitate subsequent return visits. External devices include mobile phones, monitoring systems, etc. The Bluetooth connection status is displayed through the display unit 16.

[0053] like Figure 1 , 5 As shown, in order to protect the device, the intelligent wound auxiliary rehabilitation device also includes a housing 26, in which the liquid pump 1, the power supply device 6, and the control unit 7 are installed. The top of the housing 26 is provided with an opening, and a cover 27 is installed on the opening. The suction port of the liquid pump 1, the display unit 16, and the power switch 23 are installed on the cover 27. The first rheostat P4 is configured as a knob installed on the cover 27, and the device has a simple structure and a small size.

[0054] The housing 26 is also provided with a flexible elastic belt, which is provided with a lock buckle and can be worn on the patient's waist, which is convenient for installation and removal, does not restrict the patient's activities, and meets the patient's daily needs. The liquid storage container 3 is detachably arranged on the bracket 28, and the bracket 28 is assembled on the outer wall of the housing 26, which is convenient for replacing the liquid storage container 3.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
