Description

Technical Field

[0001] This invention belongs to the field of wound measurement technology, specifically relating to a portable wound measuring instrument. Background Technology

[0002] In surgical diseases, the diagnosis and treatment of acute and chronic wounds has long been a crucial part of clinical work. Therefore, rapid diagnosis and measurement of acute and chronic wounds play a vital role in patient treatment, refined wound management, disease monitoring, and wound prognosis assessment. Furthermore, accurate measurement and calculation of wound area are also essential for clinical researchers in clinical trials to determine the effectiveness of drugs in promoting wound healing or to assess the role of new tissue-engineered materials in wound healing.

[0003] With social progress and the development of science and technology, many emerging measurement technologies have gradually emerged. For example, Chinese invention application CN201911103938.5 discloses an intelligent wound outcome analyzer. This analyzer uses a non-contact scanning device to connect to the analysis device. Within a certain distance, the scanning device projects grid coordinates onto the wound and scans it from different angles. The data is then wirelessly transmitted to the analysis device for intelligent analysis of parameters such as the wound's area, shape, and contour. This enables intelligent analysis of the wound's outcome and effectively avoids the shortcomings of traditional wound analysis methods.

[0004] While the aforementioned instruments have wound measurement capabilities, they lack wound irrigation capabilities. In practical applications, some patients often require treatment outdoors, such as on the battlefield or at the scene of a car accident. In addition to wound measurement, these outdoor scenarios often involve wound cleaning and bandaging. However, carrying additional wound irrigation equipment during outdoor rescue would undoubtedly increase the difficulty of the rescue. Therefore, to address the above issues, we propose a portable wound measurement instrument. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention discloses a portable wound measuring instrument.

[0006] To achieve the above objectives, one technical solution adopted by the present invention is:

[0009] Furthermore, the upper surface of the transparent plate is lower than the upper surface of the housing. When the spray plate and the transparent plate are in contact, the outer end of the first diversion channel will be sealed by the inner wall of the housing.

[0010] Furthermore, the nozzle assembly also includes a slide cylinder and a second elastic element. The outer connecting rod is longitudinally slidably disposed within the slide cylinder. The slide cylinder is longitudinally slidably disposed within the slide groove and cannot rotate axially relative to the slide groove.

[0011] When the spray plate is in contact with the transparent plate, the upper end of the second diversion channel is aligned with the upper end of the guide channel, and the lower end of the first diversion channel is closed by the upper end of the slide cylinder.

[0012] When the spray plate is rotated clockwise by N degrees around the slide cylinder via the external connecting rod in a state aligned with the housing, the lower end of the first diversion channel will be aligned with the upper end of the guide channel, and the upper end of the second diversion channel will be closed by the upper end of the slide cylinder.

[0013] Furthermore, the upper end of the spray plate is provided with a receiving groove, and the second diversion groove includes a piston groove opened in the outer connecting rod and communicating with the receiving groove, an upper section of the second diversion groove connected to the lower end of the piston groove for alignment with the guide groove, and a lower section of the second diversion groove connected to the side of the piston groove for communication with the liquid storage container.

The pulling member includes a second limiting member located below the fixed cylinder and slidably connected to the piston groove, an inner connecting rod fixedly connected to the upper end of the second limiting member and slidably passing through the fixed cylinder, and a pulling block fixedly connected to the upper end of the inner connecting rod and matching the shape of the receiving groove.

[0015] The third elastic element is disposed between the fixed cylinder and the second limiting element to push the second limiting element downward so that the pull block abuts against the bottom of the receiving groove;

[0016] When the pull block abuts against the bottom of the receiving groove, the second limiting member will be located on the lower side of the upper end of the lower section of the second diversion groove.

[0017] Furthermore, a third diversion groove penetrating the side of the spray plate is provided at the lower end of the spray plate;

[0018] When the spray plate and the transparent plate are in contact, the lower end of the third diversion channel is closed by the upper end of the slide cylinder, and the outer end of the third diversion channel is closed by the inner wall of the housing.

[0019] When the spray plate is rotated clockwise by M degrees around the slide cylinder via the external connecting rod in a state aligned with the housing, the lower end of the third diversion channel will be aligned with the upper end of the guide channel, and the lower end of the first diversion channel and the upper end of the second diversion channel will both be closed by the upper end of the slide cylinder. In this state, the outer end of the third diversion channel will point towards the transparent plate.

[0020] Furthermore, a fourth diversion groove communicating with the first diversion groove is provided at the lower end of the spray plate;

[0021] When the spray plate and the transparent plate are in contact, the lower end of the fourth diversion channel is closed by the upper end of the slide cylinder, and the outer end of the fourth diversion channel is closed by the inner wall of the housing.

Detailed Implementation

[0049] The invention will now be further described with reference to the accompanying drawings.

[0050] Reference Figure 1-19 As shown, this embodiment of a portable wound measuring device includes a cylindrical housing 1 with an elongated hole-shaped cross-section. The housing 1 houses a control module and a wound scanning module. In this embodiment, the control module has an upper circuit board 21 and a lower circuit board 22, spaced apart and connected by a ribbon cable. The upper circuit board 21 includes a control chip for analysis and calculation, a data storage chip, and a communication chip for wireless communication with an external computing device. The lower circuit board 22 includes a display screen 221 for displaying various parameters and operating status, a power / data interface 222 for charging and data transmission, a battery 223 for power supply, and control buttons 224 for controlling the operation of various electrical components. In this embodiment, the wound scanning module includes a projector 31 located on the upper end of the upper circuit board 21 for projecting a grid pattern onto a target object, a rangefinder 32 for distance measurement, and an image acquisition device 33, which is a camera.

[0051] During wound measurement, the projector 31 projects a grid image onto the wound. The image acquisition unit 33 then acquires the wound image with the grid and transmits it to an external computing device. The distance between the wound and the wound scanning module is measured by the rangefinder 32 to determine the calculation ratio. The computer then analyzes and calculates the wound size. Notably, the image acquisition unit 33 can directly acquire images for magnified observation of wound details, and the acquired images can be stored in a storage chip for later review. Furthermore, to protect the scanning module 3, a transparent plate 11 is fixed to the housing 1 above the scanning module 3; the control module is also located below the transparent plate 11.

[0052] To enable the wound measuring instrument to have a wound rinsing function, the portable wound measuring instrument in this embodiment is also equipped with a cleaning device. Specifically, the cleaning device includes a transparent liquid storage container 41, a nozzle assembly, and a water pump 43.

[0053] The liquid storage container 41 is used to store rinsing fluid for rinsing wounds. In this embodiment, the liquid storage container 41 is fixed to the lower end of the housing 1 and has a strip-shaped cross-section. It is also made of transparent material so that the user can easily observe the amount of liquid inside. A connection interface 410 is provided at the upper end of the liquid storage container 41, which is connected to the pump inlet of the water pump 43 through a second pipe 4302. A filling interface 411 is provided at the lower end of the liquid storage container 41 for adding rinsing fluid. A cap 412 is threadedly connected to the filling interface 411 to seal it. It is worth mentioning that after the cap 412 is tightened, the lower end of the cap 412 is flush with the lower end of the liquid storage container 41, so that the instrument can be placed upright.

[0054] In this embodiment, the nozzle assembly includes a nozzle unit and a first elastic member 422. The nozzle unit includes a spray plate 4221 whose shape matches the cross-sectional shape of the housing 1 and can be retracted into the housing 1; an outer connecting rod 4222 connected to the lower end of the spray plate 4221 and longitudinally slidably disposed in the slide groove 111 and sealingly penetrating the liquid storage container 41; a first limiting member 4223 disposed at the lower end of the outer connecting rod 4222; and a first diversion groove 4224 opened in the length direction of the spray plate 4221 and located at the end away from the outer connecting rod 4222 and communicating with the pumping end of the water pump 43. In this embodiment, the first diversion groove 4224 penetrates the front end of the spray plate 4221. In this embodiment, the first elastic element 422 is a helical spring. The first elastic element 422 is sleeved on the outside of the outer connecting rod 4222 and disposed inside the liquid storage container 41. Under the elastic force of the first elastic element 422, the first limiting element 4223 will be pushed downward to push the outer connecting rod 4222 downward so that the spray plate 4221 and the transparent plate 11 remain in contact.

[0055] In this embodiment, when the spray plate 4221 is aligned and abuts against the transparent plate 11, it can protect the upper surface of the transparent plate 11, preventing the surface of the transparent plate 11 from getting dirty when the instrument is not in use and affecting subsequent use. If wound measurement is required, the spray plate 4221 is rotated open, that is, the part of the transparent plate 11 located above the wound scanning module is exposed, so that the wound scanning module can perform wound measurement.

[0056] When the wound needs to be rinsed, the water pump 43 is controlled by the control button 224. When the water pump 43 is working, it pumps the rinsing fluid in the storage container 41 into the first diversion tank 4224. The rinsing fluid that enters the first diversion tank 4224 is sprayed out from the front end of the first diversion tank 4224, thus rinsing the patient's wound. In this way, medical staff can rinse the wound directly with the measuring instrument before measuring the wound. This reduces the difficulty of operation during outdoor rescue and can improve the efficiency of rescue to a certain extent. The overall structure is easy for medical staff to carry in the field and is conducive to efficient rescue on the battlefield or at the scene of a car accident.

[0057] It is worth mentioning that the upper surface of the transparent plate 11 is lower than the upper surface of the housing 1. When the spray plate 4221 is aligned with the transparent plate 11, the spray plate 4221 will retract into the housing 1 and remain in contact with the transparent plate 11. In this state, the housing 1 will restrict the spray plate 4221 from rotating freely, thus protecting the transparent plate 11. In addition, in this state, the outer end of the first diversion channel 4224 will be sealed by the inner wall of the housing 1, which can protect the front end of the first diversion channel 4224 and prevent foreign objects from entering and clogging it. When the spray plate 4221 needs to be used, it is pulled outward against the elastic force of the first elastic member 422. After the spray plate 4221 extends out of the housing 1, it can be rotated. Rotate it to a position where it is not aligned with the transparent plate 11 and release it. At this time, the first elastic member 422 will rebound and abut against the upper end of the housing 1. At this time, the front end of the first diversion channel 4224 opens, thus allowing the rinsing operation to be performed.

[0058] When the spray plate 4221 is retracted into the housing 1, if the water pump 43 operates unexpectedly, for example, if the user accidentally touches the control button 224 that controls the operation of the water pump 43, the first diversion channel 4224 may drain water. To avoid waste caused by the discharge of rinsing liquid at this time, this embodiment has the following design. Specifically, the nozzle assembly also includes a slide cylinder 423 and a second elastic member 424. The outer connecting rod 4222 is longitudinally slidably disposed in the slide cylinder 423, and the slide cylinder 423 is longitudinally slidably disposed in the slide groove 111 and cannot rotate axially relative to the slide groove 111. In this embodiment, the second elastic member 424 is a helical spring and is disposed between the liquid storage container 41 and the slide cylinder 423 to push the slide cylinder 423 upward so that the slide cylinder 423 and the spray plate 4221 remain in contact. In this embodiment, the inner end of the first diversion groove 4224 extends downward through the spray plate 4221, and the lower end of the spray plate 4221 is provided with a second diversion groove that extends through the lower end of the outer connecting rod 4222. The upper end of the slide cylinder 423 is provided with a guide groove 4231 that matches the first diversion groove 4224, and the lower end of the guide groove 4231 is connected to the pump outlet of the water pump 43 through the first pipe 4301.

[0059] To restrict the axial rotation of the slide cylinder 423 relative to the slide groove 111, in this embodiment, a vertical groove 4233 is provided on the side of the slide cylinder 423, and a protrusion 1111 extends into the vertical groove 4233 on the inner side of the slide groove 111. The protrusion 1111 cooperates with the vertical groove 4233 to restrict the axial rotation of both while keeping the slide cylinder 423 able to slide axially relative to the slide groove 111.

[0060] When the spray plate 4221 is in contact with the transparent plate 11, that is, when the spray plate 4221 and the transparent plate 11 are aligned, the entire instrument is in a retracted state. The upper end of the second diversion channel will be aligned with the upper end of the guide channel 4231, and the lower end of the first diversion channel 4224 will be sealed by the upper end of the slide cylinder 423. In this state, if the water pump 43 operates unexpectedly, the rinsing fluid will enter the second diversion channel through the guide channel 4231 and be discharged from the second diversion channel into the storage container 41. In this way, the rinsing fluid will not be discharged from the first diversion channel 4224 and wasted. It is worth mentioning that this design allows the rinsing fluid in the storage container 41 to circulate and mix. It can also mix rinsing fluids that will separate after standing still, so as to make the components of the rinsing fluid evenly distributed.

[0061] When the rinsing function is needed, the spray plate 4221 is pulled away from the housing 1 so that it extends out of the housing 1. Then, the spray plate 4221 is rotated 90 degrees clockwise around the slide cylinder 423 via the external connecting rod 4222. In this state, the lower end of the first diversion channel 4224 will be aligned with the upper end of the guide channel 4231, and the upper end of the second diversion channel will be closed by the upper end of the slide cylinder 423. At this time, the rinsing liquid pumped out by the water pump 43 can be introduced into the first diversion channel 4224 through the guide channel 4231, and finally sprayed out from the front end of the first diversion channel 4224 for rinsing.

[0062] To keep the upper end of the spray plate 4221 flat and to facilitate the user in pulling the spray plate 4221 outward, this embodiment also makes the following design: Specifically, the upper end of the spray plate 4221 is provided with a receiving groove 42211, and the second diversion groove includes a piston groove 42251 opened in the outer connecting rod 4222 and communicating with the receiving groove 42211, an upper section 42252 of the second diversion groove connected to the lower end of the piston groove 42251 for alignment with the guide groove 4231, and a lower section 42253 of the second diversion groove connected to the side of the piston groove 42251 for communication with the liquid storage container 41. In addition, the nozzle assembly also includes a fixed cylinder 427, a pulling member, and a third elastic member 426. The fixed cylinder 427 is fixedly connected to the piston groove 42251. The pulling member includes a second limiting member 4251 located on the lower side of the fixed cylinder 427 and slidably connected to the piston groove 42251, an inner connecting rod 4252 fixedly connected to the upper end of the second limiting member 4251 and slidably passing through the fixed cylinder 427, and a pull block 4253 fixedly connected to the upper end of the inner connecting rod 4252 and matching the shape of the receiving groove 42211.

[0063] In this embodiment, the third elastic element 426 is a helical spring, and the third elastic element 426 is located between the fixed cylinder 427 and the second limiting element 4251. Under its own elastic force, the third elastic element 426 will push the second limiting element 4251 downward so that the pull block 4253 abuts against the bottom of the receiving groove 42211, thereby hiding the pull block 4253 in the receiving groove 42211 so that the upper end of the spray plate 4221 remains flat. It is worth mentioning that when the pull block 4253 abuts against the bottom of the receiving groove 42211, the second limiting member 4251 will be located on the lower side of the upper end of the lower section 42253 of the second diversion groove. In this way, after the spray plate 4221 is housed in the housing 1, when the water pump 43 is working, the flushing liquid entering the guide groove 4231 will enter the piston groove 42251 through the upper section 42252 of the second diversion groove. The continuously entering flushing liquid will overcome the elastic force of the third elastic member 426 and push the second limiting member 42251. Pushing upwards, when the lower end of the second limiting member 4251 passes the upper end of the lower section 42253 of the second diversion channel, the flushing fluid will be discharged into the storage container 41 through the lower section 42253 of the second diversion channel. In this state, the pull block 4253 is pushed out of the receiving groove 42211 by the second limiting member 4251 in conjunction with the inner connecting rod 4252. Therefore, the user can hold the pull block 4253 so that the user can pull the spray plate 4221 out of the housing 1 through the pull block 4253. After the water pump 43 stops working, the third elastic member 426 will rebound and drive the pull block 4253 to reset.

[0064] When this instrument is used outdoors, especially in harsh environments such as dusty battlefields, dirt inevitably adheres to the surface of the transparent plate 11, obstructing the wound scanning module and affecting its normal operation. Therefore, it is necessary to clean the surface of the transparent plate 11. To clean the surface of the transparent plate 11, this embodiment also incorporates the following design: Specifically, a third diversion groove 4226 is provided at the lower end of the spray plate 4221, penetrating the side of the spray plate 4221. When the spray plate 4221 is in contact with the transparent plate 11, that is, when the spray plate 4221 is aligned with the transparent plate 11, the lower end of the third diversion groove 4226 is sealed by the upper end of the slide cylinder 423, and the outer end of the third diversion groove 4226 is sealed by the inner wall of the housing 1 to protect the outer end of the third diversion groove 4226 and prevent blockage.

[0065] When the transparent panel 11 becomes dirty and needs cleaning, the spray plate 4221 is rotated 180 degrees clockwise around the slide cylinder 423 via the external connecting rod 4222, so that the lower end of the third diversion channel 4226 is aligned with the upper end of the guide channel 4231. In this state, the lower end of the first diversion channel 4224 and the upper end of the second diversion channel are both closed by the upper end of the slide cylinder 423. In this state, the outer end of the third diversion channel 4226 points towards the transparent panel 11. At this time, the water pump 43 is controlled to work by the control button 224. When the water pump 43 works, the flushing liquid in the storage container 41 is sent into the third diversion channel 4226 through the guide channel 4231. Finally, the flushing liquid is sprayed out from the outer end of the third diversion channel 4226, and the sprayed flushing liquid can directly rinse the transparent panel 11 to clean the dirty transparent panel 11. This cleaning method is simple and efficient, and does not require the use of other tools, which is beneficial for field rescue.

[0066] To ensure that users do not need to distinguish the rotation direction of the spray plate 4221 when using the wound irrigation function, this embodiment also incorporates the following design: Specifically, the lower end of the spray plate 4221 is provided with a fourth diversion groove 4227 that communicates with the first diversion groove 4224. When the spray plate 4221 is in contact with the transparent plate 11, the lower end of the fourth diversion groove 4227 is closed by the upper end of the slide cylinder 423, and the outer end of the fourth diversion groove 4227 is sealed by the inner wall of the housing 1 to protect the outer end of the fourth diversion groove 4227 and prevent blockage.

[0067] When it is necessary to rinse the wound, the spray plate 4221 can be rotated 90 degrees counterclockwise around the slide cylinder 423 via the external connecting rod 4222. In this state, the lower end of the fourth diversion channel 4227 will be aligned with the upper end of the guide channel 4231, and the lower ends of the first diversion channel 4224, the upper ends of the second diversion channel, and the lower ends of the third diversion channel 4226 will all be closed by the upper end of the slide cylinder 423. In this way, the rinsing fluid delivered through the guide channel 4231 will enter the fourth diversion channel 4227, and then be guided from the fourth diversion channel 4227 into the first diversion channel 4224. Since the lower end of the first diversion channel 4224 has been closed by the upper end of the slide cylinder 423, the rinsing fluid will be sprayed out from the front end of the first diversion channel 4224. At this time, wound rinsing can be performed. With this setting, medical staff do not need to distinguish the direction of rotation when using the wound rinsing function; rinsing can be performed by rotating 90 degrees clockwise or counterclockwise.

[0068] To enhance the sealing strength between the spray plate 4221 and the slide cylinder 423, the following design is implemented: Specifically, an annular groove 4232 is provided at the upper end of the slide cylinder 423, and the upper end of the guide groove 4231 penetrates the bottom wall of the annular groove 4232. The lower end of the spray plate 4221 has a convex ring 4228 coaxially arranged with the outer connecting rod 4222 and rotatably connected in the annular groove 4232. The lower ends of the first diversion groove 4224, the upper end of the second diversion groove, the lower end of the third diversion groove 4226, and the lower end of the fourth diversion groove 4227 all penetrate the lower end of the convex ring 4228. When the second elastic element 424, in conjunction with the liquid storage container 41, pushes the slide cylinder 423 upward, the bottom wall of the annular groove 4232 and the lower end of the convex ring 4228 remain in contact. This enhances the sealing strength between the spray plate 4221 and the slide cylinder 423 and stabilizes the connection between them.

[0069] In summary, this wound measuring device closely integrates wound measurement and wound rinsing functions, allowing medical personnel to rinse wounds directly using the device before measurement. The device has a compact and ingenious design, making it easy for medical personnel to carry in the field, reducing the difficulty of rescue to some extent, and is suitable for use in outdoor scenarios such as wartime.
