Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a callable wound tension reducer. Background Art

[0002] In the existing skin wound healing methods used in clinical practice and when treating deeper wounds, the most traditional method is generally to use sutures. However, sutures will cause needle wounds when closing the wound, and the sutures need to be removed again after the wound heals, which causes great damage to the wound area, and is painful and troublesome to change the dressing. In addition, the force generated by the sutures when closing the wound is a point-surface shear force, and the degree of pulling on the wound varies depending on the tightness of each thread during suturing, leaving a centipede-like scar at the wound healing site.

[0003] Although some tension reducers on the market can close wounds, after tightening and adjusting, if the user feels that the tension reducers are too tight, the tension reducers on the market often do not have a retractable readjustment function. The tension reducer needs to be torn off and another piece needs to be re-pasted, which is not only wasteful, but the wound is easily pulled during the multiple tearing and pasting processes, causing secondary damage.

[0004] In addition, most tension reducers on the market are closed by pulling the left and right sides together. If a shallow wound appears on the arm and the user wants to handle it with one hand, this elastic bandage that pulls the left and right sides together often cannot be operated by the user.

[0005] Therefore, in view of the many disadvantages of the wound tension reducers currently on the market during use, a call-back wound tension reducer is designed so that when using the product, the patient can readjust the tension of the tension reducer even after using it incorrectly, thereby avoiding product waste and secondary damage to the wound caused by multiple tearing and sticking of the product after using it incorrectly. Utility Model Content

[0006] The purpose of the utility model is to provide a call-back type wound tension reducer to solve the problems raised in the above background technology. The following technical solution is provided: a call-back type wound tension reducer, comprising:

[0007] The substrate comprises a first bonding substrate and a second bonding substrate; the first bonding substrate and the second bonding substrate are respectively bonded and fixed on both sides of the patient's wound, a pulling component and a fixing component are respectively fixed on the first bonding substrate and the second bonding substrate, and the pulling component is movably clamped in the middle of the fixing component to achieve tension between the first bonding substrate and the second bonding substrate.

[0008] The pulling assembly comprises a first base, which is fixedly connected to the surface of the first bonding substrate, and a pull bar is fixedly arranged at one end of the first base, and a pull ring is fixedly arranged at the other end of the pull bar, and the pull ring is arranged parallel to the first bonding substrate.

[0009] The middle part of the pull rod is provided with evenly arranged latching teeth, and the latching teeth are conical in shape, and the diameter of the latching teeth increases successively along the tightening direction of the pulling component.

[0010] In the technical solution, the utility model is composed of a substrate, a pulling component and a fixing component. The substrate is attached to both sides of the patient's wound. When in use, the pulling component is first clamped on the fixing component, and then the pulling component is pulled to drive the pulling component and the fixing component to approach each other, thereby achieving the approach and tension between the first attached substrate and the second attached substrate, and achieving the closure of the patient's wound.

[0011] It should be noted that in actual use of this product, the number of pulling components and fixing components can be increased according to the actual wound length. The pulling components and fixing components are placed on the surface of the first laminating substrate and the second laminating substrate respectively. This arrangement is convenient for personnel to use with one hand when operating by themselves. If used in a position where the skin tension changes greatly during activities such as joints, the pulling components and fixing components can be placed crosswise to enhance the closing force of the product.

[0012] In the present application, the pulling component is composed of a first base, a pull bar, and a pull ring, and the three are integrally formed by injection molding. The substrate can be made of hydrocolloid, non-woven fabric, or PU film according to the use environment. The pulling component and the fixing component are compounded on the surface of the substrate by means of adhesive or the like.

[0013] The pull ring is located at the end of the pull rod and is on the same water surface as the first bonding substrate and the second bonding substrate, so as to ensure that the user can easily apply force in the horizontal direction to drive the entire pulling assembly to move. The latch tooth is conical, and the taper of the cone is flat. The diameter of the cone increases successively along the tightening direction of the pulling assembly, and the length of the cone is D.

[0014] The shape of the latch teeth can be conical, saucer-shaped, triangular protrusions, etc. The pull ring can be shuttle-shaped, annular, or oblate, which is convenient for users to hold.

[0015] In any of the above technical solutions, further, the fixing component includes a second base, which is fixedly arranged on the surface of the second bonding substrate, and a buckle is fixedly provided on the second base. Two buckles are horizontally arranged and the two buckles are arranged in parallel, and openings are respectively opened on one side of the buckle, and a baffle is also provided on the lower side of the opening.

[0016] The distance d between the two buckles is less than the length D of the tooth. The tooth can be horizontally clamped between the two buckles, and the buckle and the pull strip are at the same horizontal position when the buckle is clamped. A positioning channel is also provided on one side of the second base, and the positioning channel is used to guide the pull strip.

[0017] In the technical solution, the second base and the buckle are integrally injection molded. The side of the buckle is designed in an arched shape, and an opening is set on the side of the buckle, and the opening of the opening is a wedge-shaped structure, and the inclined surface of the wedge faces outward, so as to ensure that when the pulling component cooperates with the fixing component, the clamping teeth can be smoothly inserted into the buckle through the opening, and a baffle is set at the lower end of the opening to prevent the pull strip from easily falling out from the side during use.

[0018] Because the latch teeth are tapered, the latch teeth can smoothly pass through the buckle on the fixed component to cooperate with it to complete the tension adjustment when pulling. The distance d between the two buckles is less than the length D of the latch tooth cone. Because the buckle is elastic, when the latch teeth pass through the buckle, the conical slope of the latch teeth can smoothly lift the first buckle until the end of the cone passes over the first buckle and then falls again to complete the locking. At this time, when the skin tension is opposite to the tightening tension, the tail end with a larger cone diameter can be firmly stuck on the side of the buckle. The latch teeth are designed to be conical with an arrow angle, which can cooperate with the opening through their own slope during the pulling and closing process, so that they can smoothly lift the buckle during the pulling process and complete the locking by relying on their own elasticity when the buckle completely passes through a latch tooth.

[0019] The larger circular cross-section at the end of a single clip and the rounded arch design on the side of the clip can firmly resist the tension of the skin after tightening the wound. There is a smaller opening on the side of the clip, and the end of the opening has an inverted buckle design with the inclined surface facing outward, so that when assembling, the inclined surface of the clip itself contacts the inclined surface of the opening and can be easily installed in the fixed component. Since the pull strip is only subjected to horizontal unidirectional tension and the buckle's own rebound lock during use, it is ensured that the clip will not easily fall out during use under the fixation of the buckle.

[0020] After the pulling assembly of the product of the present invention has completed the tightening adjustment, if the user feels that the tightening is excessive, the user only needs to pull the pull ring sideways to detach the pull strip from the opening to separate the pulling assembly from the fixing assembly and readjust it. According to actual use needs, the pull strip can be adjusted to the required distance and then directly buckled in or restored to the position before pulling and then re-pull and adjust. After separation, select a suitable distance to buckle the pull strip into the buckle again along the inclined surface of the opening, and continue to pull the pulling assembly along the extension direction of the pull strip to realize the reuse of the product. After incorrect use, it can be readjusted to avoid product waste and secondary damage to the wound caused by multiple tearing and sticking of the product after incorrect use.

[0021] The two sides above the positioning channel are raised, and the triple buckle design provides multi-directional and multi-angle positioning when the buckle is fixed to increase the fixed placement of the buckle. In addition, the triple buckle design also provides certain support for the buckle at the end positioning channel after the buckle exits the arch buckle during the reversible callback process, preventing the buckle rack from easily retracting and causing secondary damage to the wound, and preventing the force against skin tension from disappearing instantly and causing secondary damage to the wound. There are force application slopes on both sides of the positioning channel to facilitate users to support and apply force during pulling and adjustment operations.

[0022] It should be noted that the number of the pulling assembly and the fixing assembly in the present application can be more than two, and can be one or more. The buckle can be a screw type, a ratchet type, a cable tie type, a paddle pull type, etc., which can pass through a locking structure in one direction.

[0023] The beneficial effect of the utility model is that the pulling component and the fixing component are provided, and the pulling component and the fixing component can be assembled movably. The latch is a conical structure with an arrow angle, and the buckle is a double-arched buckle, which can effectively and evenly bear the force when supporting the latch. This prevents the buckle from easily retracting during the adjustment process to cause secondary damage to the wound and prevents the force against skin tension from disappearing instantly to cause secondary damage to the wound.

[0024] At the same time, there is a tightening and callback function between the pulling component and the fixing component. During the tightening operation, the conical inclined surface of the card tooth cooperates with the inclined surface of the arched buckle, so that the card tooth relies on the inclined surface to lift the buckle during the pulling process, and the buckle can fall back and lock in time after the single buckle stroke ends. The whole process can be completed with less force, which is convenient for users to operate by themselves. And when there is an over-adjustment phenomenon, the patient can push the card tooth out from the side of the buckle by himself, and then adjust the pull strip to the required distance according to actual use needs, and then directly buckle it in or restore it to the position before pulling and re-pull and adjust. This allows the product to adjust the tightness at will, and it can be readjusted after incorrect use to avoid product waste and secondary damage to the wound caused by multiple tearing and sticking of the product after incorrect use.

It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] Embodiment 1:

[0035] like Figure 1 , 2 As shown in , 5 and 6, this embodiment provides a callable wound tension reducer, including:

[0036] The substrate 10 includes a first laminating substrate 11 and a second laminating substrate 12; the first laminating substrate 11 and the second laminating substrate 12 are respectively laminating and fixed on both sides of the patient's wound, and a pulling component 20 and a fixing component 30 are respectively fixed on the first laminating substrate 11 and the second laminating substrate 12, and the pulling component 20 is movably clamped in the middle of the fixing component 30 to achieve tension between the first laminating substrate 11 and the second laminating substrate 12.

[0037] The pulling assembly 20 includes a first base 21 , which is fixedly connected to the surface of the first bonding substrate 11 , and a pull rod 22 is fixedly provided at one end of the first base 21 , and a pull ring 23 is fixedly provided at the other end of the pull rod 22 , and the pull ring 23 is arranged parallel to the first bonding substrate 11 .

[0038] The middle of the pull rod 22 is provided with evenly arranged latching teeth 24 , and the latching teeth 24 are conical in shape, and the diameter of the latching teeth 24 increases gradually along the tightening direction of the pulling assembly 20 .

[0039] In the technical solution, the utility model is composed of a substrate 10, a pulling component 20 and a fixing component 30. The substrate 10 is attached to both sides of the patient's wound. When in use, the pulling component 20 is first clamped on the fixing component 30, and then the pulling component 20 is pulled to drive the pulling component 20 and the fixing component 30 to approach each other, thereby achieving the approach and tension between the first attached substrate 11 and the second attached substrate 12, and achieving the closure of the patient's wound.

[0040] It should be noted that, in actual use of the product, the number of the pulling components 20 and the fixing components 30 can be increased according to the actual wound length. The pulling components 20 and the fixing components 30 are placed on the surface of the first laminating substrate 11 and the second laminating substrate 12, respectively. Such an arrangement is convenient for personnel to use with one hand when operating by themselves. If used in a position where the skin tension changes greatly during activities such as joints, the pulling components 20 and the fixing components 30 can be placed crosswise to enhance the closing force of the product.

[0041] In the present application, the pulling component 20 is composed of a first base 21, a pull strip 22, and a pull ring 23, and the three are integrally formed by injection molding. The substrate 10 can be made of materials such as hydrocolloid, non-woven fabric or PU film according to the use environment. The pulling component 20 and the fixing component 30 are composited on the surface of the substrate 10 by means of adhesive or the like.

[0042] The pull ring 23 is located at the end of the pull rod 22 and is on the same water surface as the first bonding substrate 11 and the second bonding substrate 12, so as to ensure that the user can conveniently apply force in the horizontal direction to drive the entire pulling assembly 20 to move. The latching tooth 24 is conical, and the taper of the cone is flat. The diameter of the cone increases successively along the tightening direction of the pulling assembly 20, and the length of the cone is D.

[0043] The shape of the latch teeth 24 can be conical, saucer-shaped, triangular protrusions, etc. The pull ring 23 can be shuttle-shaped, annular, or oblate, which is convenient for users to hold.

[0044] In a preferred embodiment of the present invention:

[0045] like Figure 3-6As shown, specifically, the fixing component 30 includes a second base 31, which is fixedly arranged on the surface of the second bonding substrate 12, and a buckle 32 is fixedly arranged on the second base 31. There are two buckles 32 arranged horizontally and the two buckles 32 are arranged in parallel, and openings 33 are respectively opened on one side of the buckle 32, and a baffle 35 is also provided on the lower side of the opening 33.

[0046] The distance d between the two buckles 32 is less than the length D of the tooth 24. The tooth 24 can be horizontally clamped between the two buckles 32, and the buckle 32 and the pull bar 22 are at the same horizontal position when the buckle 32 is clamped. A positioning channel 34 is also provided on one side of the second base 31, and the positioning channel 34 is used to guide the pull bar 22.

[0047] In the present technical solution, the second base 31 and the buckle 32 are integrally injection molded. The side of the buckle 32 is designed in an arched shape, and an opening 33 is set on the side of the buckle 32, and the opening of the opening 33 is wedge-shaped, with the inclined surface of the wedge facing outward, so as to ensure that when the pulling component 20 and the fixing component 30 cooperate, the latching teeth 24 can be smoothly inserted into the buckle 32 through the opening 33, and a baffle 35 is set at the lower end of the opening 33 to prevent the pull strip 22 from easily falling out from the side during use.

[0048] Since the latch 24 is tapered, the latch 24 can smoothly pass through the buckle 32 on the fixing assembly 30 to cooperate with it to complete the tension adjustment when pulling. The distance d between the two buckles 32 is less than the length D of the cone of the latch 24. Because the buckle 32 is elastic, when the latch 24 passes through the buckle 32, the conical inclined surface of the latch 24 can smoothly lift the first buckle 32 until the end of the cone passes over the first buckle 32 and then falls again to complete the locking. At this time, when the skin tension opposite to the tightening tension is applied, the tail end with a larger cone diameter can be firmly stuck on the side of the buckle 32. The latch 24 is designed as a cone with an arrow angle, which can cooperate with the opening 33 through its own slope during the pulling and closing process, so that it can smoothly lift the buckle 32 during the pulling process and complete the locking by relying on its own elasticity when the buckle 32 completely passes through a latch.

[0049] The larger circular cross-section at the end of a single clip and the rounded arch design on the side of the clip 32 can firmly resist the tension of the skin after the wound is tightened. There is a smaller opening 33 on the side of the clip 32, and the end of the opening 33 has an undercut design with the inclined surface facing outward, so that when assembled, the inclined surface of the clip 24 itself contacts the inclined surface of the opening 33 and can be easily installed in the fixing component 30. Since the pull strip 22 is only subjected to horizontal unidirectional pulling force and the buckle 32 is locked by its own rebound during use, it is ensured that the clip 24 will not easily fall out during use under the fixation of the buckle 32.

[0050] After the pulling assembly 20 of the product of the present invention has completed the tightening adjustment, if the user feels that the tightening is excessive, the user only needs to pull the pull ring 23 sideways to separate the pull strip 22 from the opening 33 to separate the pulling assembly 20 from the fixing assembly 30 and readjust. According to actual use needs, the pull strip 22 can be adjusted to the required distance and then directly buckled in or restored to the position before pulling and readjusted. After separation, select a suitable distance to buckle the pull strip 22 into the buckle 32 along the inclined surface of the opening 33 again, and continue to pull the pulling assembly 20 along the extension direction of the pull strip 22 to realize the reuse of the product. After incorrect use, it can be readjusted to avoid product waste and secondary damage to the wound caused by multiple tearing and sticking of the product after incorrect use.

[0051] The two sides above the positioning channel 34 are raised, and the triple buckle design provides multi-directional and multi-angle clamping when the clamping teeth are fixed to increase the fixed placement of the clamping teeth. In addition, the triple buckle design also provides a certain support for the clamping teeth at the end positioning channel after the clamping teeth exit the arched buckle during the reversible callback process, preventing the clamping teeth from easily retracting and causing secondary damage to the wound, and preventing the force against the skin tension from disappearing instantly and causing secondary damage to the wound. The force application slopes are provided on both sides of the positioning channel to facilitate the user to support and apply force during the pulling and adjustment operations.

[0052] It should be noted that the number of the pulling assembly 20 and the fixing assembly 30 in the present application can be more than two, and can be one or more. The buckle 32 can be a screw type, a ratchet type, a cable tie type, a paddle pull type, etc., which can pass through a locking structure in one direction.

[0053] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
