Description

Technical Field

[0001] The present invention relates to the technical field of diagnostic sampling, and in particular to a sampling device specifically used for diabetic foot and a method of use. Background Art

[0002] When sampling diabetic foot ulcers, standard practice is to meticulously collect samples from the ulcer surface using two sterile swabs. One swab is used for bacteriological culture to identify the infecting microorganism, while the other is used for molecular biology testing to further analyze the pathogen's genetic information. After collection, the samples are immediately sealed in a dedicated specimen container to ensure sample freshness and test accuracy.

[0003] When performing deep sampling of diabetic foot ulcers, traditional swabs are susceptible to contamination from epidermal secretions or other impurities as they penetrate deep into the ulcer. This can affect the accuracy of the final test results and may also lead to missed or misdiagnosed cases. Existing technical solutions primarily achieve closure by moving an external cover. However, for practical reasons, the cover may not move when inserted into the patient's ulcer, and such an operation is equivalent to rubbing back and forth on the wound, which can cause further damage.

[0004] Based on the above situation, the present invention proposes a testing device and a method for use specifically for diabetic foot. Summary of the Invention

[0005] In order to overcome the shortcoming that the swab is easily contaminated by other secretions during deep sampling, the present invention provides a sampling device specifically for diabetic foot and a method of use.

[0006] A device specifically for inspecting diabetic foot, comprising a handle, the handle being fixedly connected to a cylinder, a clamping cylinder being slidably connected inside the cylinder, the clamping cylinder being inserted into the handle, the clamping cylinder being slidably connected to the handle, two splints being slidably connected to the end of the clamping cylinder away from the handle, the splints being used to clamp a swab, an isolation cylinder being clamped inside the cylinder, the ends of the clamping cylinder and the swab being both located inside the isolation cylinder, a push block being slidably connected to the outside of the handle, the push block being fixedly connected to the end of the clamping cylinder close to the handle.

[0007] Furthermore, the splint is provided with a plurality of grooves for increasing the friction between the swab and the splint.

[0008] Furthermore, it also includes a push rod, which is slidably connected to the middle of the handle, and the push rod is slidably connected to the clamping cylinder. One end of the push rod close to the clamping cylinder is fixedly connected to a guide frame for guiding the splint, a tension spring is fixedly connected between the push rod and the clamping cylinder, and a first spring is fixedly connected between the clamping cylinder and the handle, and the elastic coefficient value of the first spring is greater than the elastic coefficient value of the tension spring.

[0009] Furthermore, a guide groove symmetrically distributed along the guide frame is formed on a side of the guide frame close to the clamping plate, and the guide groove of the guide frame is slidably connected to the adjacent clamping plate.

[0010] Furthermore, it also includes a conical column, which is fixedly connected to the side of the push rod close to the handle and the clamping cylinder. The clamping cylinder is slidably connected to the side of the conical column close to the clamping cylinder. The clamping rod is squeezed into fit with the conical column. A second spring is fixedly connected between the clamping rod and the clamping cylinder. A groove is provided on the side of the handle close to the clamping rod for limiting the clamping rod.

[0011] Furthermore, the vertical length of the clamping slot is longer than the vertical length of the clamping rod.

[0012] Furthermore, it also includes a U-shaped frame, which is fixedly connected to the side of the guide frame close to the clamping plate. The U-shaped frame is slidably connected to a T-shaped plate for assisting in pushing out the swab, and a third spring is fixedly connected between the T-shaped plate and the U-shaped frame.

[0013] Furthermore, it also includes a first magnet, which is fixedly connected to the push block, and a second magnet is fixedly connected to the side of the handle close to the push block, and the second magnet is located below the first magnet. The first magnet moves downward and contacts the second magnet and is attracted to each other by magnetic force, and the magnetic force is greater than the elastic force of the first spring.

[0014] Furthermore, it also includes at least two spring pieces, which are fixedly connected in the cylinder. The isolation cylinder is squeezed and matched with the spring pieces. At least two key slots are opened in the cylinder for clamping and limiting the isolation cylinder.

[0015] A method for using a diabetic foot inspection device, comprising the following steps: S1. Clamping and installing a swab for sampling between the two clamping plates; S2. Installing the isolation cylinder on the cylinder by pushing it in a tight fit manner; S3, holding the handle, inserting the isolation tube downward into the deep of the diabetic foot ulcer; S4, pressing the push block downward so that the clamping plate in the clamping cylinder drives the swab to extend out of the isolation cylinder for sampling; S5. Push the push block upward, so that the clamping plate in the clamping cylinder drives the swab upward into the isolation cylinder; S6. Pull out and remove the isolation tube, take out the swab and place it in a special specimen container for inspection.

[0016] The beneficial effect is that the present invention isolates and protects the swab through the isolation tube before and after sampling, and only when it reaches the deep part of the ulcer is the internal swab pushed out of the isolation tube for sampling. In this way, the effect of deep ulcer detection is achieved, and the swab will not contact the epidermis before and after sampling, reducing the contamination of the swab by epidermal secretions or other impurities, thereby improving the accuracy of the detection results.

[0017] The present invention can push the two splints apart by pressing the push rod downward, so that the swab automatically falls into the special specimen container, avoiding accidental contact of the sample on the swab by the hand when removing the swab, thereby avoiding infection.

[0018] When the push rod is pressed downward, the conical column squeezes the clamping rod to slide rightward and clamp it into the clamping groove, preventing the clamping cylinder from sliding and preventing the clamping plate from completely releasing the swab, thereby avoiding affecting the removal of the swab.

[0019] After the sampling is completed, the push rod is pressed downward to make the T-shaped plate move downward synchronously to assist in pushing out the swab, thereby preventing the swab from being stuck in the groove and unable to fall out smoothly when the splint releases the swab.

[0020] The present invention uses the mutual magnetic attraction between the first magnet and the second magnet to enable the clamping cylinder to maintain its position after sliding downward, thereby reducing the force applied to the push block and lowering the difficulty of inspection operation.

[0021] The invention ensures that the isolation cylinder is firmly mounted on the key slot of the cylinder by aligning the key of the isolation cylinder with the key slot and by the action of the spring sheet, thereby preventing the isolation cylinder from being loosened during sampling.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0035] Example 1: A device for checking diabetic foot, combined with the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 6, including a handle 1, the interior of the handle 1 is hollow, the bottom of the handle 1 is fixedly connected to a cylinder 2, the upper and lower ends of the cylinder 2 are open, the interior of the cylinder 2 is hollow, the cylinder 2 is slidably connected to a clamping cylinder 3 in the up and down directions, the top of the clamping cylinder 3 penetrates into the handle 1, the clamping cylinder 3 is slidably connected to the handle 1, and the lower side of the clamping cylinder 3 is slidably connected to two splints 4, which are used to clamp a swab for sampling. The swab (such as a medical cotton swab or a non-woven swab) is designed to absorb and Fix a certain amount of liquid sample. Unless the operator uses too much force or makes an operational error that causes excess sample to adhere, there will generally be no problem of sample dripping. The opposite end faces of the two splints 4 are provided with multiple grooves 401, which are used to increase the friction between the swab and the splint 4. An isolation cylinder 5 is clamped in the cylinder 2, and the ends of the clamping cylinder 3 and the swab are both located in the isolation cylinder 5. The isolation cylinder 5 is a non-closed design, which is convenient for cleaning and disinfection. The outside of the handle 1 is slidably connected to a push block 6, which is fixedly connected to the upper end of the clamping cylinder 3.

[0036] Before taking the sample, first install the swab clamp for sampling between the two plywood 4, and then clamp the isolation tube 5 on the cylinder 2 by pushing it in a tight fit to realize the installation of the isolation tube 5. Then, hold the handle 1 and first extend the isolation tube 5 deep into the diabetic foot ulcer. Then press the push block 6 downward. The push block 6 drives the clamping tube 3 to slide downward relative to the handle 1, cylinder 2 and isolation tube 5. The plywood 4 in the clamping tube 3 drives the swab to extend from the isolation tube 5 for sampling. Afterwards, push the push block 6 upward. The push block 6 drives the clamping tube 3 to slide upward relative to the handle 1, cylinder 2 and isolation tube 5. The plywood 4 in the clamping tube 3 drives the swab to extend upward into the isolation tube 5. Finally, pull out and remove the isolation tube 5, remove the swab and put it into a special specimen container for inspection.

[0037] In summary, the present invention isolates and protects the swab through the isolation tube 5 before and after sampling. Only when it reaches the deep part of the ulcer, the internal swab is pushed out of the isolation tube 5 for sampling. In this way, the effect of deep ulcer detection is achieved, and the swab will not contact the epidermis before and after sampling, reducing the contamination of the swab by epidermal secretions or other impurities, thereby improving the accuracy of the test results.

[0038] Combined with attachment Figure 5 , also includes a push rod 7, the push rod 7 is connected to the middle of the handle 1 in a sliding manner along the up and down directions, the push rod 7 is slidably connected to the clamping cylinder 3, the bottom end of the push rod 7 is fixedly connected to a guide frame 8, the bottom of the guide frame 8 is provided with guide grooves symmetrically distributed along the guide frame 8, the guide grooves of the guide frame 8 are slidably connected to the adjacent splints 4, for guiding the splints 4 so that the adjacent splints 4 move away from or approach each other, a tension spring 9 is fixedly connected between the lower part of the push rod 7 and the clamping cylinder 3, and a first spring 10 is fixedly connected between the upper part of the clamping cylinder 3 and the handle 1, and the elastic coefficient value of the first spring 10 is greater than the elastic coefficient value of the tension spring 9.

[0039] When installing the swab, first manually press the top of the push rod 7 downward. Since the elastic coefficient of the first spring 10 is greater than the elastic coefficient of the tension spring 9, under the strong pulling force of the first spring 10, the clamping cylinder 3 is almost stationary relative to the grip 1 and the cylinder 2, and the push rod 7 slides downward relative to the clamping cylinder 3, the tension spring 9 is stretched, and the push rod 7 drives the guide frame 8 to slide downward. The guide frame 8 pushes the two splints 4 to slide toward the side away from each other through the guide groove, and then the swab is placed between the two splints 4. Release the push rod 7. Under the resetting action of the tension spring 9, the push rod 7 drives the guide frame 8 to move upward. The guide frame 8 pulls the two splints 4 to slide toward each other through the guide groove, thereby achieving the effect of automatically clamping the swab. After the sampling is completed, the swab can be automatically dropped into the special specimen container by pressing the push rod 7 downward again, thereby avoiding accidental touching of the sample on the swab by the hand when removing the swab, thereby avoiding infection.

[0040] Combined with attachment Figure 7 and attached Figure 8 , it also includes a tapered column 11, which is fixedly connected to the side of the push rod 7 close to the handle 1 and the clamping cylinder 3. The upper side of the clamping cylinder 3 is slidably connected with a clamping rod 12 in the horizontal direction. The clamping rod 12 is squeezed and fitted with the tapered column 11. A second spring 13 is fixedly connected between the clamping rod 12 and the clamping cylinder 3. A clamping groove 14 for limiting the clamping rod 12 is opened on the side of the handle 1 close to the clamping rod 12. The vertical length of the clamping groove 14 is longer than the vertical length of the clamping rod 12, which is conducive to the clamping rod 12 being clamped into the clamping groove 14, thereby improving the fault tolerance of the clamping operation.

[0041] During the above-mentioned pressing process of the push rod 7, part of the pressing force will be dispersed to the clamping cylinder 3, causing the clamping cylinder 3 to slide relative to the handle 1 and the cylinder 2, thereby causing the pressing force to be unable to be concentrated on the clamping plate 4, and then causing the clamping plate 4 to be unable to completely release the swab, affecting the removal of the swab. Although the strong pulling force of the first spring 10 can prevent the clamping cylinder 3 from sliding relative to the handle 1 and the cylinder 2 to a certain extent, in order to further enhance the effect, it is necessary to fix the clamping cylinder 3 on the handle 1 through the clamping rod 12 when pressing the push rod 7. The specific operation is as follows: When the push rod 7 is pressed downward, the push rod 7 drives the cone 11 to move downward, and the cone 11 squeezes the clamping rod 12 to slide into the clamping groove 14, and the second spring 13 is compressed. In this way, the clamping tube 3 can be prevented from sliding when the push rod 7 is pressed.

[0042] When the push rod 7 is released, the push rod 7 drives the cone column 11 to move upward and no longer presses the clamping rod 12. The second spring 13 resets and drives the clamping rod 12 to slide back and out of the clamping groove 14 without affecting the subsequent sliding of the clamping cylinder 3.

[0043] Combined with attachment Figure 9, also includes a U-shaped frame 15, the U-shaped frame 15 is fixedly connected to the bottom side of the guide frame 8, the U-shaped frame 15 is slidably connected to a T-shaped plate 16 for assisting in pushing out the swab, and a third spring 17 is fixedly connected between the T-shaped plate 16 and the U-shaped frame 15.

[0044] When the push rod 7 is pressed downward before clamping the swab, the guide frame 8 drives the U-shaped frame 15 to slide downward, and the U-shaped frame 15 drives the T-shaped plate 16 to move downward synchronously through the third spring 17. At this time, the splint 4 is separated, and when the swab is placed between the two splints 4, the swab stick will push the T-shaped plate 16 upward, causing the T-shaped plate 16 to slide upward relative to the U-shaped frame 15, and the third spring 17 is compressed. When the push rod 7 is released, the guide frame 8 drives the U-shaped frame 15 to slide upward relative to the T-shaped plate 16, and the third spring 17 is reset. At this time, the splint 4 clamps the swab. After the sampling is completed, when the push rod 7 is pressed downward again, the guide frame 8 drives the U-shaped frame 15 to slide downward, and the U-shaped frame 15 drives the T-shaped plate 16 to move downward synchronously through the third spring 17. The T-shaped plate 16 assists in pushing out the swab to prevent the swab from being stuck in the groove 401 and unable to fall out smoothly when the splint 4 releases the swab.

[0045] Combined with attachment Figure 10 , also includes a first magnet 18, the first magnet 18 is fixedly connected to the push block 6, and a second magnet 19 is fixedly connected to the side of the handle 1 close to the push block 6, the second magnet 19 is located below the first magnet 18, the first magnet 18 moves downward and contacts the second magnet 19 and is attracted to each other by magnetic force, and the magnetic force is greater than the elastic force of the first spring 10.

[0046] When pushing the push block 6 downward so that the clamping cylinder 3 slides downward relative to the handle 1, thereby moving the swab out of the isolation cylinder 5 for sampling, due to the addition of the first spring 10, the medical worker needs to always apply a large force to the push block 6 to counteract the elastic force of the first spring 10, which is difficult for medical workers with insufficient or unstable strength to operate. In order to reduce the difficulty of sampling operation, during the downward pushing of the push block 6, the push block 6 drives the first magnet 18 to move downward until it contacts the second magnet 19. Through the mutual magnetic attraction between the first magnet 18 and the second magnet 19, the clamping cylinder 3 maintains the position after sliding downward. After the sampling is completed, the push block 6 is pushed upward again to separate the first magnet 18 from the second magnet 19. The elastic force of the first spring 10 assists in pushing the first magnet 18 from the second magnet 19 to separate.

[0047] Combined with attachment Figure 11 , and also includes two spring pieces 20, which are fixedly connected to the cylinder 2, the isolation cylinder 5 and the spring pieces 20 are squeezed together, and two key grooves 21 are opened in the cylinder 2 for clamping and limiting the isolation cylinder 5.

[0048] In order to more firmly clamp the isolation cylinder 5 in the cylinder 2, when inserting the isolation cylinder 5 into the cylinder 2, first align the key of the isolation cylinder 5 with the keyway 21, and then push the isolation cylinder 5 upward. The isolation cylinder 5 squeezes the spring piece 20, and the spring piece 20 deforms adaptively. Under the action of the spring piece 20, the isolation cylinder 5 is firmly installed on the keyway 21 of the cylinder 2 to prevent the isolation cylinder 5 from loosening during sampling.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
