Description

Technical Field

[0001] The utility model relates to the technical field of medical care appliances, in particular to a disposable fluorescent wound probe. Background Art

[0002] Clinically, many reasons can cause some special wounds, such as sinus tracts, anorectal fistulas, undercover, diabetic foot gangrene, etc. The above sinus tracts, fistulas, undercover and diabetic foot gangrene all need regular dressing changes. The depth of the wound is an important criterion for judging whether the wound surface has improved. For deep wounds with undercover, sinus tracts and fistulas, a disposable wound probe will be used to measure the depth of the wound during dressing changes.

[0003] Announcement No. "CN202437123U" provides a probe for measuring wound depth. When changing dressings for patients with sinus tracts, fistulas, undercover gangrene and diabetic foot gangrene, the wound is routinely cleaned and disinfected. Then, the handle is held and the front end of the probe is gently inserted into the wound until it reaches the bottom of the wound. At this time, the depth of the wound can be accurately read from the probe on the skin of the wound.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the probe can measure the depth of the wound, the length of the needle body is limited, so it cannot detect deep wounds during actual use, and the probe does not have the ability to self-luminesce and cannot illuminate the internal tissue of the wound, resulting in medical staff being unable to properly explore the probe deep inside the wound. Although some probes in the prior art are long enough, they are not foldable and are therefore inconvenient to carry around. In addition, most of the existing probes with illumination capabilities use batteries and lighting lamp beads to illuminate the wound, but this structure is not only complex in structure, but also inconvenient to disinfect, and will also increase the manufacturing cost of the probe when used once, and is not very practical.

[0034] Please refer to Figures 1 to 5, in a preferred embodiment provided by the present utility model, a disposable fluorescent wound probe includes a disposable probe 100 and a guiding head 200. The guiding head 200 is provided at the lower end of the disposable probe 100. The disposable probe 100 and the guiding head 200 are of an integral structure. The guiding head 200 is semi-circular in shape. The semi-circular guiding head 200 makes the lower end of the disposable probe 100 smoother, so that the disposable probe 100 can be inserted into the wound more smoothly. A first digital scale line 101 is provided on the front side of the circumferential side of the disposable probe 100. The first digital scale line 101 facilitates medical staff to detect the depth of the wound by means of the disposable probe 100. A folding assembly is provided inside the disposable probe 100, and the folding assembly can further increase the use length of the disposable probe 100. Light-emitting components are provided on the circumferential side of the disposable probe 100 and the circumferential side of the folding assembly, and the light-emitting components enable both the disposable probe 100 and the folding assembly to have the ability of self-luminescence.

[0035] The folding assembly includes an extension probe 301 and a connecting pin 304. The extension probe 301 is installed inside the disposable probe 100. The material of the extension probe 301 is the same as that of the disposable probe 100. Both the extension probe 301 and the disposable probe 100 are for single use. After the extension probe 301 is unfolded upward, it can increase the use length of the disposable probe 100. A connecting pin 304 is installed on the upper side inside the extension probe 301. The material of the connecting pin 304 is medical stainless steel. The connecting pin 304 made of medical stainless steel facilitates the movable connection between the extension probe 301 and the disposable probe 100, so that the extension probe 301 has the ability to be folded. A buckle groove 303 is formed on the lower end surface of the extension probe 301. The buckle groove 303 facilitates medical staff to swing and fold or unfold the extension probe 301 by hand.

[0036] The upper end of the lengthened probe 301 is semi-circular. The lengthened probe 301 with a semi-circular upper end has better swinging smoothness. A storage groove 305 is formed on the right side of the annular side surface of the disposable probe 100, and the storage groove 305 is matched with the lengthened probe 301. The storage groove 305 facilitates the folding and storage of the lengthened probe 301 inside the disposable probe 100. A positioning hole 306 is formed on the upper side of the annular side surface of the lengthened probe 301. The positioning hole 306 facilitates the positioning of the locking bead 307 for the lengthened probe 301 in place after folding or unfolding. A limiting cavity 310 is formed on the upper side inside the disposable probe 100. The limiting cavity 310 is matched with the pressing piece 308. The limiting cavity 310 facilitates the installation of the pressing piece 308 and the compression spring 309 inside the disposable probe 100. A compression spring 309 is installed inside the limiting cavity 310. The right end of the compression spring 309 is provided with a pressing piece 308. The middle position of the right end face of the pressing piece 308 is provided with a locking bead 307, and the locking bead 307 is matched with the positioning hole 306. The compression spring 309 can press the pressing piece 308 so that the pressing piece 308 presses the locking bead 307, and then the locking bead 307 can be clamped in the corresponding positioning hole 306.

[0037] A second digital scale line 302 is arranged on the front side of the annular side surface of the lengthened probe 301. The scale spacing of the first digital scale line 101 is the same as that of the second digital scale line 302. The second digital scale line 302 with the same scale spacing as the first digital scale line 101 can continue the indicating length of the first digital scale line 101, so as to measure the depth of a deep wound with the lengthened probe 301 after unfolding.

[0038] In a further embodiment of the present utility model, by filling the left side of the annular side surface of the disposable probe 100 with the first luminous powder 402, the first luminous powder 402 can emit fluorescence through the first transparent baffle 401 to irradiate the surrounding wound tissue, and the second luminous powder 403 can emit fluorescence through the second transparent baffle 404 to irradiate the surrounding wound tissue, so that medical staff can well explore the disposable probe 100 and the lengthened probe 301 deep into the wound.

[0039] The light-emitting component includes a first transparent barrier 401 and a first phosphor 402. The left side of the circumferential side of the disposable probe 100 is filled with the first phosphor 402. The material of the first phosphor 402 is a fluorescent powder. After being irradiated by natural light, fluorescent lamp light, ultraviolet light, etc., the first phosphor 402 made of fluorescent powder can store light energy. After the light irradiation stops, it slowly releases the light energy in the form of fluorescence, enabling the left side of the circumferential side of the disposable probe 100 to have the self-luminous ability, so as to irradiate the surrounding wound tissue in the form of fluorescence. The first transparent barrier 401 is adhered to the left side of the circumferential side of the disposable probe 100. The material of the first transparent barrier 401 is medical PVC. The first transparent barrier 401 made of medical PVC can not only block the first phosphor 402, but also enable the fluorescence emitted by the first phosphor 402 to irradiate outward.

[0040] The right side of the circumferential side of the lengthened probe 301 is filled with a second phosphor 403. The material of the second phosphor 403 is a fluorescent powder. After being irradiated by natural light, fluorescent lamp light, ultraviolet light, etc., the second phosphor 403 made of fluorescent powder can store light energy. After the light irradiation stops, it slowly releases the light energy in the form of fluorescence, enabling the right side of the circumferential side of the lengthened probe 301 to have the self-luminous ability, so as to irradiate the surrounding wound tissue in the form of fluorescence. The second transparent barrier 404 is adhered to the right side of the circumferential side of the lengthened probe 301. The material of the second transparent barrier 404 is medical PVC. The second transparent barrier 404 made of medical PVC can not only block the second phosphor 403, but also enable the fluorescence emitted by the second phosphor 403 to irradiate outward.

[0041] Working principle: When it is necessary to detect the depth of a shallow wound, the medical staff only needs to hold the upper end of the disposable probe 100 by hand, and then can gently insert the disposable probe 100 into the shallow wound until the guiding head 200 reaches the bottom of the wound. At this time, the medical staff only needs to observe the position of the external skin of the wound at the first digital scale line 101 to know the depth of the wound. When it is necessary to detect the depth of a deep wound, the medical staff first holds the lower end of the disposable probe 100 with one hand, and the index finger of the other hand buckles the buckle groove 303 and swings the lengthened probe 301 outward by 180 degrees (refer to Figure 2) so that the extended probe 301 after expansion increases the use length of the disposable probe 100. At this time, the medical staff only needs to pinch the upper end of the extended probe 301 with their hand and gently insert the disposable probe 100 into the deep wound. Similarly, keep the guiding head 200 reaching the bottom of the wound. At this time, the medical staff only needs to observe the position of the external skin of the wound at the second digital scale line 302 to know the depth of the wound. And during this process, the compression spring 309 can squeeze the locking bead 307 through the squeezing piece 308, so that the locking bead 307 is clamped in the corresponding positioning hole 306 to assist in positioning the extended probe 301 in place of expansion, avoiding the extended probe 301 in place of expansion from loosening easily during use; when the disposable probe 100 and the extended probe 301 are inside the wound, the first phosphor 402 will emit fluorescence through the first transparent baffle 401 to irradiate the surrounding wound tissue, and the second phosphor 403 will emit fluorescence through the second transparent baffle 404 to irradiate the surrounding wound tissue, so that the medical staff can well explore the disposable probe 100 and the extended probe 301 deep into the wound. When the wound inspection is completed, only need to discard the disposable probe 100 and the extended probe 301 in the external medical trash can.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
