Description

Technical Field

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

[0002] Daily cleaning of surgical wounds is an important part of the wound healing process. Correct cleaning methods can effectively prevent infection and promote wound healing.

[0003] At present, the commonly used method is to use a cotton swab dipped in iodine to clean the area around the wound. For large-area wounds, medical staff need to replace multiple cotton swabs for surface treatment, which is slow to clean and easily causes the wound to be exposed 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 apply pressure to stop bleeding before bandaging, which leads to a waste of medical resources and easily leads to a shortage of medical staff.

[0030] A liquid storage bag 51 for storing disinfectant is welded on the central block 3, and a water pump (not shown in the figure) for pumping disinfectant is arranged in the liquid storage bag 51, and the water pump is electrically connected to the control panel; the output end of the water pump is connected with a water pipe, in this example, the water pipe is a stretchable telescopic pipe, and the water pipe is respectively connected with a first hydraulic rod and a second hydraulic rod, the first hydraulic rod is located in the second slide groove 21, and the first hydraulic rod is located between the slider 22 and the mounting block 2.

[0031] The second hydraulic rod is located inside the central block 3, and the output end of the second hydraulic rod is fixedly connected to a pressing layer 33. In the present embodiment, the pressing layer 33 is a medical cotton layer, and the diameter of the pressing layer 33 is larger than the diameter of the second hydraulic rod; and the water pipes connecting the first hydraulic rod and the second hydraulic rod are respectively connected to a liquid flow regulating valve for controlling the liquid flow in the water pipe, and the liquid flow regulating valve is electrically connected to the control panel; when the pressing layer 33 moves to the farthest end, the two sides of the pressing layer 33 respectively abut against the contact block 4.

[0032] A contact block 4 is hingedly connected to one end of the pressing mechanism away from the mounting block 2, and an infrared temperature sensor 6 for measuring skin temperature is fixedly connected to the bottom of the contact block 4. The infrared temperature sensor 6 is electrically connected to a control panel and a battery for distinguishing normal skin and wounds based on skin temperature. The control panel is also used to control the ball screw mechanism to drive the pressing mechanism to contact the wound based on the skin temperature; as shown in the figures, when specifically selected, the control panel includes an embedded microcontroller, such as the STM32H7 series, etc.

[0033] The control panel and the battery are both prior art and will not be described in detail in this embodiment.

[0034] A spraying mechanism for spraying disinfectant on the wound is also provided at the bottom of the contact block 4; the spraying mechanism includes a drainage pipe 5 connected to the liquid storage bag 51. In this example, the drainage pipe 5 is a stretchable telescopic tube, and the drainage pipe 5 is connected to the output end of the water pump. The drainage pipe 5 is connected to a solenoid valve, and the solenoid valve is electrically connected to the control panel; the end of the drainage pipe 5 away from the liquid storage bag 51 is located at the bottom of the contact block 4, and the height of the end of the contact block 4 close to the pressing layer 33 is lower than the height of the end of the contact block 4 away from the pressing layer 33, and the height of the infrared temperature sensor 6 is higher than the height of the drainage pipe 5.

[0035] The specific implementation process is as follows: First, the device is manually placed on the wound surface to be treated, and the patient and medical staff observe the movement and disinfection conditions inside the support block 1 through the transparent shielding layer 11, providing an operating basis for the auxiliary operation of the patient and medical staff, so that the wound is located at the center of the support block 1. The present invention is suitable for surgical trauma wounds, especially for narrow and long wounds.

[0036] During use, the ball screw mechanism drives the nut block 14 to reciprocate, and 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 adapt to the disinfection of wounds in different positions, reduce the manual adjustment steps of medical staff, and improve the treatment efficiency.

[0037] The wound that needs to be disinfected and cleaned is moved cyclically by the ball screw mechanism, driving the infrared temperature sensor 6 under the ball screw mechanism to detect the temperature of the skin surface, so as to determine the fuzzy wound area based on the difference between the temperature of the wound and the normal skin. During the movement of the ball screw mechanism, the spraying mechanism evenly spreads the disinfectant to perform preliminary disinfection on the wound and normal skin, so as to reduce the residual bacteria on the surface during the cleaning process, and at the same time, the dirt, dandruff and other attachments on the skin surface and the scab on the wound are infiltrated, and the dirt, dandruff and other attachments on the skin surface are infiltrated to facilitate subsequent separation from the skin, so as to ensure the cleanliness of the skin around the wound, reduce the bacterial breeding environment, and thus facilitate the healing of the wound; and the scab on the wound is infiltrated to reduce the generation of hard water chestnuts, thereby reducing the collision damage of the ball screw mechanism and the scab on the wound during the contact process, so as to be suitable for the disinfection needs of narrow and long wounds. And through the height difference between the infrared temperature sensor 6 and the drain pipe 5, the disinfectant discharged by the drain pipe 5 is reduced to contact with the infrared temperature sensor 6, and the corrosion damage of the disinfectant to the infrared temperature sensor 6 is reduced.

[0038] 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 supporting block 1 to reduce the contact between dust and bacteria in the outside air and the wound, reduce the risk of infection, and reduce the internal disinfectant from floating in the outside air, reducing the interference of the disinfectant on the external environment.

[0039] When the electric push rod 23 pushes the contact block 4 to move, the control panel is used to control the liquid flow of the liquid flow regulating valve to control the extension length of the first hydraulic rod and the second hydraulic rod. The first hydraulic rod is used to adjust the distance between adjacent mounting blocks 2 so that the contact blocks 4 on the electric push rod 23 are located on both sides of the wound, which makes it easier for the electric push rod 23 to press and stop bleeding on both sides of the wound during operation, and facilitates the extension of the pressing layer 33 at the center to press and stop bleeding on the wound, thereby facilitating wound healing. It is also easier for the deformable center block 3 to be deformed through the movement of the slider 22 and the electric push rod 23 to adapt to the needs of pressing and stopping bleeding for wounds of different narrow and elongated shapes, so as to ensure the accuracy of pressing and stopping bleeding.

[0040] At the same time, when the pressing layer 33 is extended, the contact block 4 hinged on the electric push rod 23 is pushed to rotate, so that the contact block 4 moves away from the center, so that the contact block 4 scrapes on both sides with the wound as the center, so as to reduce impurities or residues remaining on the skin near the wound, so as to ensure the cleanliness near the wound and facilitate subsequent wound healing.

[0041] Example 2

[0042] The difference from Example 1 is that a first slide groove 12 is opened on both sides of the support block 1, the first slide groove 12 is located below the screw rod 13, and the center rod slides in cooperation with the first slide groove 12; a clamping block 31 is also threadedly connected to the center rod, and the clamping block 31 is against the support block 1; the auxiliary rod 32 is clamped with the electric push rod 23.

[0043] The specific implementation process is as follows: the movement of the center rod is guided by the first slide groove 12 to improve the stability of the center rod during movement, and then the auxiliary rod 32 is detachably connected to the electric push rod 23 to facilitate the separation and engagement of the electric push rod 23 with the auxiliary rod 32 after movement; in the process of the center block 3 driving the center rod to move, the clamping block 31 is moved on the center rod by rotating to resist the support block 1 to fix the center block 3 to remain stationary, thereby improving the stability of the pressing layer 33 under the center block 3 when pressure is applied.

[0044] Example 3

[0045] The difference from the second embodiment is that a plurality of bristles 41 are fixedly connected to one side of the contact block 4 close to the central block 3 .

[0046] The specific implementation process is as follows: the bristles 41 are in flexible contact with the skin and the wound to reduce the collision stimulation when the bristles 41 contact the wound; at the same time, when the contact block 4 drives the bristles 41 to rotate, the bristles 41 are used to provide deformation space to facilitate the bristles 41 to clean both sides with the wound as the center, reduce impurities and bacteria near the wound, and ensure the cleanliness of the wound.

[0047] Example 4

[0048] The difference from Example 3 is that a number 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; a snap-fitting block 15 is slidably fitted on the side of the mounting block 2 close to the nut block 14, a magnet layer (not shown in the figure) is fixedly connected to the side of the snap-fitting block 15 close to the nut block 14, and a protrusion is welded at the center of the side of the snap-fitting block 15 close to the nut block 14.

[0049] When the magnetism of the electromagnet is opposite to that of the magnet layer, the protrusion is located outside the mounting block 2 ; when the magnetism of the electromagnet is the same as that of the magnet layer, the protrusion is located inside the mounting block 2 .

[0050] The specific implementation process is as follows: when the two mounting blocks 2 move at the same time, the electromagnet is started to adsorb and fix the locking block 15. When the nut block 14 slides on the screw rod 13, the mechanism installed on the mounting block 2 is driven to move, so that the infrared temperature sensor 6 on the contact block 4 can determine the wound position of the skin covered inside the support block 1 to keep the mounting block 2 covering the wound surface.

[0051] After the wound is cleaned, the electromagnet is turned off through the control panel. At this time, the protrusion on the locking block 15 extends out of the mounting block 2, and the nut block 14 continues to move. During the movement of the screw rod 13, the nut block 14 will resist the protruding protrusion to push the mounting block 2 on one side of the wound to move away from the wound, and the skin around the wound is scraped and cleaned by the bristles 41 on the contact block 4, and then the screw rod 13 drives the nut block 14 to move in the opposite direction to clean the surrounding skin on the other side of the wound and ensure the cleanliness of the area around the wound.

[0052] Example 5

[0053] The difference from Example 4 is that the control panel is used to enter and store temperature acquisition control instructions and position marks of each infrared temperature sensor 6, the ball screw mechanism rotates at a uniform speed based on the temperature acquisition control instructions, and the infrared temperature sensor 6 adds timing instructions and position marks to the skin temperature at the current time based on the temperature acquisition control instructions issued by the control panel.

[0054] The control panel is used to compare the skin temperatures corresponding to the same position mark in sequence over time. If the skin temperature at the current time is greater than the skin temperature 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 screw rod 13 movement instruction; the screw rod 13 movement instructions corresponding to adjacent position marks are obtained, the middle value of the screw rod 13 movement instructions corresponding to the maximum value and the minimum value is calculated, and the screw rod 13 movement instruction corresponding to the middle value is sent to the ball screw mechanism; then the phase difference between the screw rod 13 movement instruction corresponding to the middle value and each screw rod 13 movement instruction is calculated, and based on the phase difference, an adjustment instruction is sent to the liquid flow control valve corresponding to the first hydraulic rod.

[0055] If the skin temperature at the current time is less than or equal to the skin temperature before and after the current time, a normal skin mark is added based on the skin temperature at the current time.

[0056] For example, since the screw rod 13 rotates at a uniform speed to drive the nut block 14 to slide at a uniform speed, the movement distance of the nut block 14 corresponds to the timing instruction. The movement instruction of the screw rod 13 is calculated to determine the movement distance of the mounting block 2 during the adjustment process driven by the first hydraulic rod, so as to control the mounting block 2 to clean both sides of the wound, so as to realize the identification and positioning of the wound and improve the accuracy of wound treatment.

[0057] Example 6

[0058] The difference from Example 5 is that restraints are clamped on both sides of the support block 1, and Velcro is adhered to the side of the restraint away from the support block 1.

[0059] The specific implementation process is as follows: the support block 1 is conveniently installed on the skin surface through the binding belt to improve the stability of the device so that the internal device can perform wound cleaning.

[0060] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. 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 work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
