Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a portable wound treatment and cleaning device for general surgery. Background Art

[0002] The daily cleaning of surgical wounds is an important part of the wound healing process. The correct cleaning method can effectively prevent infection and promote wound healing.

[0003] Currently, the commonly used method is usually to dip a cotton swab in iodophor and then clean the periphery of the wound. For large-area wounds, medical staff need to replace multiple cotton swabs for surface treatment, resulting in slow cleaning efficiency and easy exposure of the wound to the air for a long time, increasing the risk of bacterial infection. At the same time, for patients with continuous bleeding wounds, medical staff need to perform compression hemostasis before dressing, which leads to a waste of medical resources and is prone to the phenomenon of insufficient medical staff.

[0004] CN211357096U discloses a wound cleaning device for general surgery, including a base, a cleaning water tank, a cleaning table and a buffer member. One side of the top of the base is fixed with a push handle, and the other side of the base is fixed with a control panel. Universal wheels are arranged at the four corners of the bottom of the base. The inside of the base is evenly provided with a bearing plate through a buffer member, and one end of the top of the bearing plate is fixed with a cleaning water tank. A motor is fixed at the bottom end of the inside of the cleaning water tank, and a rotating shaft is fixed at the output end of the motor. Stirring members are evenly fixed on both sides of the rotating shaft. A temperature sensor is fixed on one side of the inside of the cleaning water tank. Although this device has a cleaning function, due to its large volume, dependence on manual operation, lack of wound recognition and positioning functions, and single cleaning method, it cannot achieve the goal of replacing manual cleaning and disinfection of wounds, improving the treatment efficiency, and shortening the continuous treatment time of medical staff.

[0005] Therefore, there is an urgent need to develop a portable wound treatment and cleaning device for general surgery, which can replace manual treatment and cleaning of wounds and shorten the continuous treatment time of medical staff. Summary of the Invention

[0046] Embodiment 1

[0047] As shown in the attached Figures 1 to 7As shown in the figure: A portable wound treatment and cleaning device for general surgery, including a support block 1 for fitting to the skin. A number of mounting blocks 2 are slidably fitted on the top of the support block 1. Ball screw mechanisms for driving the mounting blocks 2 to move are provided at both ends of the mounting blocks 2. A pressing mechanism for flushing the wound is slidably fitted at the bottom of the mounting blocks 2.

[0048] Among them, the ball screw mechanism includes a motor fixedly connected to the support block 1. A screw rod 13 is coaxially clamped to the output shaft of the motor. The screw rod 13 is rotatably fitted with the support block 1. The mounting block 2 is a long strip-shaped block, and the screw rod 13 is perpendicularly arranged with the mounting block 2. A nut block 14 is slidably fitted on the screw rod 13, and the nut block 14 is connected to the mounting block 2. A retractable shielding layer 11 is adhesively bonded between the mounting block 2 and the support block 1. The shielding layer 11 is a transparent layer, and in specific implementation, a transparent plastic material can be used.

[0049] The pressing mechanism includes an electric push rod 23 slidably fitted with the mounting block 2. Sliders 22 are welded to one end of each electric push rod 23. A number of uniformly arranged second chutes 21 are opened on the mounting block 2, and the sliders 22 are respectively located in the second chutes 21. The other end of the electric push rod 23 is hinged to a contact block 4. A deformable central block 3 is provided between adjacent horizontally arranged electric push rods 23. Auxiliary rods 32 are provided between the central block 3 and the electric push rods 23. A central rod is provided between the central block 3 and the support block 1. The central rod is welded to the central block 3 and is slidably fitted with the support block 1.

[0050] A liquid storage bladder 51 for storing disinfectant is welded to the central block 3. A water pump (not shown in the figure) for pumping the disinfectant is provided in the liquid storage bladder 51. The water pump is electrically connected to the control panel. The output end of the water pump is communicated with a water pipe. In this example, the water pipe is a stretchable telescopic pipe. The water pipe is respectively communicated with a first hydraulic rod and a second hydraulic rod. The first hydraulic rod is located in the second chute 21 and is located between the slider 22 and the mounting block 2.

[0051] The second hydraulic rod is located inside the central block 3. The output end of the second hydraulic rod is fixedly connected to a pressing layer 33. In this embodiment, the pressing layer 33 is a medical cotton layer, and the diameter of the pressing layer 33 is larger than that of the second hydraulic rod. And the water pipes communicated with the first hydraulic rod and the second hydraulic rod are respectively communicated with liquid flow regulating valves for controlling the liquid flow in the water pipes. The liquid flow regulating valves are electrically connected to the control panel. When the pressing layer 33 moves to the farthest end, both sides of the pressing layer 33 are respectively abutted against the contact block 4.

[0052] One end of the pressing mechanism away from the mounting block 2 is hinged with a contact block 4. A bottom of the contact block 4 is fixedly connected to an infrared temperature sensor 6 for measuring skin temperature. The infrared temperature sensor 6 is electrically connected to a control panel and a storage battery for distinguishing normal skin and wound areas based on the skin temperature. The control panel is further configured to control, based on the skin temperature, a ball screw mechanism to drive the pressing mechanism to contact the wound area; not shown in the figure. During specific selection, the control panel includes an embedded microcontroller, such as the STM32H7 series, etc.

[0053] Moreover, both the control panel and the storage battery belong to the prior art and will not be elaborated in this embodiment.

[0054] A spraying mechanism for spraying disinfectant based on the wound area is further provided at the bottom of the contact block 4; the spraying mechanism includes a liquid discharge pipe 5 communicating with a liquid storage bag 51. In this example, the liquid discharge pipe 5 is a stretchable telescopic pipe. The liquid discharge pipe 5 is communicated with an output end of a water pump. The liquid discharge pipe 5 is communicated with an electromagnetic valve, and the electromagnetic valve is electrically connected to the control panel; one end of the liquid discharge pipe 5 away from the liquid storage bag 51 is located at the bottom of the contact block 4, and a height of one end of the contact block 4 close to the pressing layer 33 is lower than a height of one end of the contact block 4 away from the pressing layer 33, and a height of the infrared temperature sensor 6 is higher than a height of the liquid discharge pipe 5.

[0055] The specific implementation process is as follows:

[0056] First, manually place the device on the surface of the wound to be treated. Patients and medical staff can observe the movement and disinfection conditions inside the support block 1 through the transparent shielding layer 11, providing an operation basis for the auxiliary operations of patients and medical staff, and making the wound located at the center of the support block 1. The present invention is applicable to surgical trauma wounds, especially to wounds with a long and narrow shape.

[0057] During use, drive the nut block 14 to reciprocate through the ball screw mechanism. The nut block 14 drives the mounting block 2 to reciprocate inside the support block 1, so that the infrared temperature sensor 6, the pressing mechanism, and the spraying mechanism at the bottom of the mounting block 2 can adaptively disinfect wounds at different positions, reducing the manual adjustment steps of medical staff and improving the treatment efficiency.

[0058] The wound to be disinfected and cleaned is circularly moved by a ball screw mechanism, driving the infrared temperature sensor 6 below the ball screw mechanism to detect the temperature of the skin surface, so as to determine the fuzzy wound area based on the difference in temperature between the wound and normal skin. During the movement of the ball screw mechanism, the spraying mechanism evenly spreads the disinfectant to preliminarily disinfect the wound and normal skin, reducing the bacterial residue on the surface during the cleaning process. At the same time, the dirt, dandruff and other attachments on the skin surface and the scabs at the wound are infiltrated. After the dirt, dandruff and other attachments on the skin surface are infiltrated, it is convenient to separate them from the skin later, ensuring the cleanliness of the skin around the wound and reducing the bacterial growth environment, thus facilitating the healing of the wound. After the scabs at the wound are infiltrated, the hard edges are reduced, and further, the collision damage during the contact between the ball screw mechanism and the scabs at the wound is reduced, meeting the disinfection needs of long and narrow wounds. And through the height difference between the infrared temperature sensor 6 and the drain pipe 5, the disinfectant discharged from the drain pipe 5 is prevented from contacting the infrared temperature sensor 6, reducing the corrosion damage of the disinfectant to the infrared temperature sensor 6.

[0059] At the same time, during the movement of the mounting block 2, the deformable shielding layer 11 is used to shield the cavity inside the support block 1, reducing the contact between dust and bacteria in the external air and the wound, reducing the risk of infection, and also reducing the dispersion of the internal disinfectant into the external air and the interference of the disinfectant to the external environment.

[0060] During the process of the electric push rod 23 pushing the contact block 4 to move, the control panel is used to control the liquid flow rate of the liquid flow regulating valve, so as to control the extended lengths of the first hydraulic rod and the second hydraulic rod. By adjusting the distance between adjacent mounting blocks 2 through the first hydraulic rod, the contact block 4 on the electric push rod 23 is located on both sides of the wound, which is convenient for the electric push rod 23 to press and stop bleeding on both sides of the wound during operation, facilitating the pressing layer 33 in the center to extend to press and stop bleeding the wound, and facilitating the wound healing; it is also convenient to drive the deformable center block 3 to deform through the movement of the slider 22 and the electric push rod 23, meeting the need for pressing and stopping bleeding of wounds with different long and narrow wound shapes, and ensuring the accuracy of pressing and stopping bleeding.

[0061] At the same time, after the pressing layer 33 extends out, it pushes the contact block 4 hinged on the electric push rod 23 to rotate, making the contact block 4 move away from the center, so that the contact block 4 scrapes from the wound to both sides, reducing the impurities or residues remaining on the skin near the wound, ensuring the cleanliness near the wound, and facilitating the subsequent wound healing.

[0062] Embodiment 2

[0063] The difference from Embodiment 1 is that first chutes 12 are formed on both sides of the support block 1. The first chutes 12 are located below the lead screw 13, and the center rod is in sliding fit with the first chutes 12; a clamping block 31 is also threadedly connected to the center rod, and the clamping block 31 abuts against the support block 1; the auxiliary rod 32 is snap-connected to the electric push rod 23.

[0064] The specific implementation process is as follows: The movement of the center rod is guided by the first chutes 12 to improve the stability of the center rod during movement. Then, the detachable connection between the auxiliary rod 32 and the electric push rod 23 is utilized to facilitate the separation and snap-fixing of the electric push rod 23 and the auxiliary rod 32 after the electric push rod 23 moves; during the movement of the center block 3 driving the center rod, the clamping block 31 is rotated to move along the center rod to abut against the support block 1 to fix the center block 3 in place, improving the stability when the pressing layer 33 below the center block 3 applies pressure.

[0065] Embodiment 3

[0066] The difference from Embodiment 2 is that a plurality of bristles 41 are fixedly connected to the side of the contact block 4 close to the center block 3.

[0067] The specific implementation process is as follows: The bristles 41 are in flexible contact with the skin and the wound to reduce the impact stimulation when the bristles 41 contact the wound; at the same time, during the rotation of the contact block 4 driving the bristles 41, the bristles 41 provide a deformation space to facilitate the cleaning of the bristles 41 from the center of the wound to both sides, reducing impurities and bacteria near the wound and ensuring the cleanliness of the wound.

[0068] Embodiment 4

[0069] The difference from Embodiment 3 is that a plurality of electromagnets (not shown in the figure) are fixedly connected to the nut block 14, and the electromagnets are electrically connected to the control panel; engaging blocks 15 are slidably fitted on the sides of the mounting blocks 2 close to the nut block 14, a magnet layer (not shown in the figure) is fixedly connected to the side of the engaging block 15 close to the nut block 14, and a convex block is welded at the center of the side of the engaging block 15 close to the nut block 14.

[0070] When the electromagnet and the magnet layer have opposite magnetic polarities, the convex block is located outside the mounting block 2; when the electromagnet and the magnet layer have the same magnetic polarities, the convex block is located inside the mounting block 2.

[0071] The specific implementation process is as follows: When the two mounting blocks 2 move simultaneously, the electromagnet is activated to adsorb and fix the engaging block 15. During the sliding of the nut block 14 on the lead screw 13, the mechanism mounted on the mounting block 2 is driven to move, so that the infrared temperature sensor 6 on the contact block 4 can determine the position of the wound on the skin covered inside the support block 1 to keep the mounting block 2 covering the wound surface.

[0072] After the wound cleaning is completed, the electromagnet is turned off through the control panel. At this time, the protrusion on the engaging block 15 extends outside the mounting block 2. During the continuous movement of the nut block 14 on the lead screw 13, the nut block 14 will abut against the protruding protrusion to push the mounting block 2 on one side of the wound to move away from the wound. The bristles 41 on the contact block 4 are used to scrape and clean the skin around the wound. Then, the lead screw 13 drives the nut block 14 to move in the reverse direction to clean the skin around the other side of the wound, ensuring the cleanliness around the wound.

[0073] Example 5

[0074] The difference from Example 4 is that the control panel is used to input and store the temperature acquisition control instructions and the position marks of each infrared temperature sensor 6. The ball screw mechanism rotates at a constant speed based on the temperature acquisition control instructions, and the infrared temperature sensor 6 adds a timing instruction and a position mark to the skin temperature at the current time based on the temperature acquisition control instructions issued by the control panel.

[0075] The control panel is used to compare the skin temperatures corresponding to the same position mark in sequence of time. If the skin temperature at the current time is greater than the skin temperatures before and after the current time, a wound mark is added based on the skin temperature at the current time, and then the timing instruction corresponding to the skin temperature at the current time is converted into a movement instruction for the lead screw 13; obtain the movement instructions of the lead screw 13 corresponding to adjacent position marks, calculate the intermediate value of the movement instructions of the lead screw 13 corresponding to the maximum value and the minimum value, and send the movement instruction of the lead screw 13 corresponding to the intermediate value to the ball screw mechanism; then calculate the difference value between the movement instruction of the lead screw 13 corresponding to the intermediate value and each movement instruction of the lead screw 13, and send an adjustment instruction to the liquid flow regulating valve corresponding to the first hydraulic rod based on the difference value.

[0076] If the skin temperature at the current time is less than or equal to the skin temperatures before and after the current time, a normal skin mark is added based on the skin temperature at the current time.

[0077] For example, since the lead screw 13 rotates at a constant speed to drive the nut block 14 to slide at a constant speed, the moving distance of the nut block 14 corresponds to the timing instruction. By calculating the movement instruction of the lead screw 13, it is convenient to determine the moving distance during the adjustment of the mounting block 2 driven by the first hydraulic rod, so as to control the mounting block 2 to clean both sides of the wound, realizing the identification and positioning of the wound and improving the accuracy of wound treatment.

[0078] Example 6

[0079] The difference from Example 5 is that binding straps are clamped on both sides of the support block 1, and a magic tape is adhered to the side of the binding strap away from the support block 1.

[0080] The specific implementation process is as follows: The support block 1 is conveniently installed on the skin surface through the restraint band, improving the stability of the device so as to facilitate the wound cleaning work of the internal device.

[0081] The above description of the embodiments is to enable those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the present invention is not limited to the above embodiments, and all improvements and modifications made by those skilled in the art without departing from the scope of the present invention according to the disclosure of the present invention should be within the protection scope of the present invention.
