Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a wound repair auxiliary dressing device. Background Art

[0002] General dressing change supplies include two dressing bowls, one for dry dressings such as sterile gauze and oil gauze strips, and the other for wet dressings such as iodine cotton balls, alcohol cotton balls or wet gauze; a curved tray for dressings and drainage materials removed from the wound surface, and dirty materials such as cotton balls and dressings used during dressing changes. Two dressing forceps (one with teeth and one without teeth). Sometimes, depending on the specific conditions of the wound surface, drainage strips (tubes), sterile scissors, probes, necessary topical medications, bandages, abdominal bandages or wide adhesive tapes are also required;

[0003] The specific steps for changing the wound dressing are as follows: the first step is to remove the outer bandage and dressing of the wound by hand. When tearing off the adhesive tape, you should tear it off from the outside of the wound to the inside. You can gently push and rub the edge of the adhesive tape on the skin with your fingers. After it is lifted up, use one hand to gently press the local skin, and use the other hand to pull the lifted adhesive tape, close to the skin surface (i.e. parallel to the skin surface) and slowly remove it in the opposite direction. Do not pull it off vertically to avoid pain or tearing off the epidermis; the second step is to remove the inner layer of the wound with sterile tweezers. When peeling it off, it should be done along the long axis of the wound. If the inner layer of the wound dressing is soaked with pus, you can Soak it with normal saline, and then gently peel it off along the long axis of the wound after the dressing is separated from the wound. During the dressing change process, one of the two dressing tweezers should be kept in a relatively sterile state at all times, and they should not be used carelessly without distinguishing between dirty and clean ones; the third step is to clean the wound. First, use iodine-containing cotton balls to disinfect the skin within at least 5 cm around the wound, and then wipe the wound surface with new iodine-containing cotton balls; the fourth step is to cover the new dressing. You need to disinfect the skin around the wound again, and then cover the wound with sterile gauze. The outermost layer can be fixed with tape or bandage; the fifth step is to properly handle dirt.

[0004] The above-mentioned wound dressing operation has the following defects: two tweezers are needed to clamp and replace the cotton balls, which is troublesome to operate. If the operation is not done properly, it is easy to cause wound infection;

[0005] If the dressing material on the inner layer of the wound is soaked with pus and cannot be peeled off, it is necessary to use a syringe to draw saline solution and put it on the dressing material, or use tweezers to pick up a dry cotton ball and dip it in saline solution to soak the dressing material. After the dressing material is separated from the wound, it can be peeled off. The operation steps are cumbersome and reduce the work efficiency of medical staff. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a wound repair auxiliary dressing device, which effectively solves the problem of cumbersome operating steps and affecting dressing efficiency when changing wound dressings.

[0011] The invention has novel concept, ingenious structure, convenient operation and strong practicality. When the guide column is not inserted into the inclined groove or the horizontal groove, the two clamping rods are relatively squeezed to simulate the function of tweezers to clamp and uncover the auxiliary materials.

[0012] When the guide post is inserted into the transverse groove or the inclined groove by adjusting the position of the slide plate, and then the two clamping rods are relatively squeezed, the two swing plates push the iodine-containing cotton ball on the lower side downward, and the iodine-containing cotton ball on the lower side falls from the storage hole to between the two clamping rods. The lower ends of the two clamping rods are loaded with iodine-containing cotton balls, and then the wound surface is disinfected. When the clamping rods are released, the used iodine-containing cotton balls fall into the curved plate, the swing plate rotates 360 degrees, and the slide plate and the slider are reset. When the two clamping rods are relatively squeezed next time, the new iodine-containing cotton balls are replaced. The operation is simple, and the steps of repeatedly clamping and replacing cotton balls when using two tweezers in the traditional way are solved, so aseptic requirements are improved and the probability of wound infection is reduced.

[0013] An annular cavity, a control panel and a connecting hole are provided, and physiological saline can flow out by pressing the control panel to soak the auxiliary materials adhering to the wound surface. The method is convenient to use, and saves the time of traditional methods of drawing physiological saline with a syringe or using tweezers to grasp a dry cotton ball and dip it in physiological saline, thereby improving the efficiency of dressing change.

[0031] In order to realize the detachable connection between the annular block 14 and the storage tube 1 and to smoothly insert the upper end of the clamping rod 16 into the notch 13, an annular groove 24 is provided on the lower side of the storage tube 1, the annular block 14 is interference fit with the annular groove 24, the upper side of the annular groove 24 is connected with the corresponding empty groove, and the opposite ends of the two sliders 4 are connected with the inner end surface of the empty groove via the positioning compression springs 25.

[0032] In order to enable the slide plate 5 to move forward and backward on the slider 4, the slider 4 is provided with a guide groove 26 in the forward and backward direction and in an inverted T shape. The lower side of the slide plate 5 is slidably connected to the guide groove 26. The opposite sides of the two empty grooves are respectively connected to the T-shaped grooves in the forward and backward direction. A U-shaped frame 27 with an opening facing the center line of the storage tube 1 is slidably connected in the T-shaped groove. The slide plate 5 is located in the corresponding U-shaped frame 27, and the U-shaped frame 27 can move forward and backward.

[0033] In order to enable the U-shaped frame 27 to move forward and backward, the rear end of the U-shaped frame 27 is connected to the rear side of the T-shaped slot via a reset spring 28. The two U-shaped frames 27 are respectively provided with push grooves 29 with openings facing outward on the opposite sides. The rear side of the push groove 29 is an inclined surface with the outer end tilted backward. The left and right sides of the storage tube 1 are respectively slidably connected with T-shaped rods 30. The large end of the T-shaped rod 30 is located on the outside of the storage tube 1 and the small end thereof is inserted into the T-shaped slot and can contact the corresponding inclined surface.

[0034] In order to enable the guide rod to remain inserted into the inclined groove 6, that is, to limit the slide plate 5, a circular ring 31 is rotatably connected to the outer side of the storage tube 1, and a first arc groove 32 with an opening facing inward is respectively provided on the left and right sides of the circular ring 31. The free ends of the two first arc grooves 32 in the counterclockwise direction are respectively connected to the second arc groove 33, and the radius of the second arc groove 33 is greater than the radius of the first arc groove 32. The connection between the first arc groove 32 and the second arc groove 33 is an inclined surface. The large end of the T-bar 30 is located in the corresponding second arc groove 33, and the stepped surface of the T-bar 30 is connected to the outer wall of the storage tube 1 via a limit spring 34.

[0035] In order to prevent the iodine cotton ball 36 from slipping between the two clamping rods 16, the shape of the two clamping rods 16 after extending out of the through slot is arc-shaped, the two clamping rods 16 are oppositely arc-mouthed and have a structure with a wide top and a narrow bottom, and the distance between the upper ends of the two clamping rods 16 is greater than the distance between their lower ends.

[0036] In order to better prevent the multiple iodine cotton balls 36 from sliding down from the storage hole 2 under the action of gravity, the inner diameter of the retaining ring 3 is smaller than the maximum diameter of the iodine cotton balls 36 .

[0037] In order to prevent the iodine cotton balls 36 in the storage tube 1 from being contaminated, a protective tube 35 is threadedly connected to the lower end of the storage tube 1 .

[0038] When the present invention is in use, the annular cavity 17 is filled with physiological saline, the storage hole 2 is filled with iodine cotton balls 36, the swing plate 12 is located between the two iodine cotton balls 36 at the bottom, the guide column 9 is not inserted into the inclined groove 6, the annular block 14 is installed on the storage tube 1, and the upper end of the clamping rod 16 is inserted into the corresponding notch 13. At this time, the distance between the lower ends of the two clamping rods 16 is equal to the inner diameter of the storage hole 2, the control board 19 blocks the flow hole 18, and the guide column 9 is located in the initial state directly behind the lower transverse groove 7;

[0039] When changing the dressing on the patient's wound, the medical staff will peel off the outer dressing material, unscrew the protective tube 35 from the storage tube 1, hold the storage tube 1, and squeeze the two clamping rods 16 with the thumb and index finger relative to each other to clamp the inner dressing material. The elastic sheet 15 is squeezed, and the clamping rod 16 drives the slider 4 and the slide plate 5 to move and squeeze the positioning spring 25. During this process, the swing plate 12 remains stationary, that is, the iodine cotton ball 36 does not fall, and the two clamping rods 16 move relative to each other to peel off the inner dressing material on the wound surface, loosen the two clamping rods 16, and the clamping rod 16 drives the slider 4 and the slide plate 5 to reset under the action of the elastic sheet 15 and the positioning spring 25; if the inner dressing material is soaked with pus When adhering to the wound surface, the front side of the storage tube 1 is located directly above the inner layer of dressing material. The medical staff presses the control plate 19 backward, and the control plate 19 moves backward and squeezes the control compression spring 21. When the connecting hole 20 is connected with the flow hole 18, the saline in the annular cavity 17 flows on the inner layer of dressing material through the flow hole 18 and the connecting hole 20. After the dressing material is soaked, the control plate 19 is released. The control plate 19 moves forward under the action of the control compression spring 21, so that the connecting hole 20 is no longer connected with the flow hole 18, and the saline no longer flows out. After the inner layer of dressing material is separated from the wound surface, the medical staff operates the two clamping rods 16 to peel the inner layer of dressing material off the wound surface.

[0040] Then, the medical staff rotates the ring 31 clockwise (see the accompanying drawings in the specification). Figure 6), the inclined surfaces between the two second arc grooves 33 and the first arc groove 32 squeeze the large ends of the corresponding T-shaped rods 30 respectively, so that the two T-shaped rods 30 move relative to each other and squeeze the limit spring 34, and the small end of the T-shaped rod 30 squeezes the inclined surface of the push groove 29, so that the U-shaped frame 27 moves backward and squeezes the reset spring 28, and the U-shaped frame 27 drives the slide plate 5 to move backward on the slide block 4, and the guide column 9 is gradually inserted into the lower side transverse groove 7. When the large end of the T-shaped rod 30 is located in the first arc groove 32, the rotating ring 31 stops, and the position of the T-shaped rod 30 and the U-shaped frame 27 is limited. The guide post 9 is fixed, that is, the guide post 9 remains inserted into the transverse groove 7; at this time, when the thumb and index finger of the medical staff squeeze the two clamping rods 16, the upper end of the clamping rod 16 drives the slider 4 and the slide plate 5 to move toward the iodine cotton ball 36 and squeeze the elastic sheet 15 and the positioning compression spring 25. At the same time, the inclined groove 6 pushes the guide post 9 to drive the rotating shaft 8 to rotate via the rocker, and the first gear 10 and the second gear 11 are engaged to make the swing plate 12 swing, that is, the swing plate 12 on the left side swings clockwise, and the swing plate 12 on the right side swings counterclockwise, and the two swing plates 12 squeeze the iodine cotton ball 36 on the lower side downward. , the iodine cotton ball 36 is squeezed and moves downward. When the maximum width of the iodine cotton ball 36 moves to the bottom of the retaining ring 3, the iodine cotton ball 36 falls downward under the action of gravity. At this time, as the two clamping rods 16 continue to move relative to each other, the iodine cotton ball 36 falls between the lower sides of the two clamping rods 16. When the slide plate 5 moves to the horizontal groove 7 on the upper side of the guide column 9, the lower ends of the two clamping rods 16 clamp the iodine cotton ball 36, and the swing plate 12 rotates 180°. The medical staff keeps the clamping rod 16 clamping the cotton ball and wipes and disinfects the area around the wound. New iodine cotton needs to be replaced When the ball 36 is moved, the used iodine cotton ball 36 is aligned with the curved plate, and the medical staff loosens the two clamping rods 16. The two clamping rods 16 move in opposite directions under the action of the elastic sheet 15 and the positioning compression spring 25. At the same time, the slider 4 and the slide plate 5 are gradually reset, and the guide column 9 continues to drive the rotation under the action of the inclined groove 6 to produce a unidirectional rotation, so that the first gear 10 and the second gear 11 are engaged to drive the swing plate 12 to continue to swing. When the two clamping rods 16 are completely reset, the swing plate 12 rotates 360°, and the used iodine cotton ball 36 falls from between the two clamping rods 16 into the curved plate;

[0041] Repeat the above operation, squeeze the two clamping rods 16 relatively, replace the new iodine cotton ball 36, and wipe and disinfect the wound surface. The operation is simple and there is no need to repeatedly use two tweezers to clamp and replace the cotton ball, which saves the time of medical staff and improves work efficiency.

[0042] After the iodine cotton ball 36 is used up, the bottle cap 23 is opened, a new iodine cotton ball 36 is loaded, the annular plug 22 is opened, and physiological saline is injected.

[0043] After the dressing change is completed, the annular block 14 and the clamping rod 16 can be pulled out from the storage tube 1, and they can be centrally disinfected. The protective tube 35 is installed on the storage tube 1 to prevent the iodine cotton ball 36 from being contaminated.
