Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable pressure bandage device after puncture. Background Technology

[0002] After a puncture, the puncture site generally needs to be bandaged with pressure. The duration of pressure application varies depending on the type of puncture. Common vascular punctures usually only require pressure application for a few minutes or a dozen minutes; while for organ punctures (such as breast biopsy and thyroid biopsy), the pressure application time is generally 6 to 8 hours. For liver tumor punctures, kidney lesion punctures, etc., intraperitoneal puncture is required, and local pressure needs to be applied for at least 10 to 12 hours after the puncture. For plastic surgery and varicose vein surgery, it may even take 2 to 7 days.

[0003] In routine vascular punctures, pressure is usually applied manually. However, for other puncture procedures with specific requirements for pressure duration, the pressure time varies and depends on the individual and the specific circumstances. Furthermore, the optimal pressure level also varies depending on the specific situation.

[0004] In addition, for some puncture procedures, the pressure application time and the bandaging time are different. That is, pressure needs to be applied for a period of time after bandaging, but the bandaged state still needs to be maintained. Moreover, some puncture procedures require changing sterile cotton or medication.

[0005] In existing technologies, the main methods used are: adding pads or elastic structures to the bandage to achieve the purpose of pressure. However, regardless of the method, the pressure cannot be adjusted as needed, and the entire bandage structure can only be replaced after the pressure is no longer needed. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable pressure bandaging device after puncture, so as to solve the problems in the prior art that it is difficult to adjust the pressure applied to the puncture site during bandaging, and that it is necessary to remove the bandage to change the cotton wool.

[0021] The knob can pull multiple hooks together by rotating on the rotating base. The two hooks can pull multiple hooks together from two opposite directions, causing multiple adhesive block components to extend toward the center of the positioning ring.

[0022] The knob is fixedly connected to both ends of the rope loop, and the knob can be rotated on the rotating base to synchronously wind the two ends of the rope loop.

[0023] As a preferred embodiment of the present invention, the rotating base is provided with an upper groove and a lower groove, and the upper groove is used to connect the thorn, and the lower groove is used to allow the rope loop on the knob to pass through.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figures 1 to 6 As shown, the present invention provides an adjustable pressure bandaging device after puncture, comprising:

[0053] Tension patch 1, which is used to attach to the periphery of the puncture site and expose the puncture site;

[0054] The binding element 2 is disposed on the tension patch 1 and is used together with the tension patch 1 to bind the limb.

[0055] Two traction components 3 are symmetrically distributed on both sides of the tension patch 1 and connected to the tension patch 1. The two traction components 3 can provide two opposing traction directions to the tension patch 1 so that the tension patch 1 is uniformly tucked towards the center to compress the puncture site.

[0056] The medicine cap 4 is movably connected to the binding 2 and is used to cover the puncture site in the central area of ​​the binding 2.

[0057] After a puncture, pressure bandaging is usually applied to the puncture site. In routine vascular punctures, pressure is usually applied manually. For some puncture procedures, the pressure application time and the bandaging time are different. That is, pressure needs to be applied for a period of time after bandaging, but the bandaged state still needs to be maintained. In current technology, the main methods used are to add pads or elastic structures to the bandage to achieve the purpose of pressure application. However, no matter which method is used, the pressure cannot be adjusted as needed, and when pressure is no longer needed, the entire bandaging structure must be replaced.

[0058] This invention utilizes a tension patch with a hollow interior and multiple movable patches for adhesion to the outside of the puncture site. After the bandage structure, consisting of the tension patch and the binding member, is applied, pressure can be applied to the puncture site by controlling the multiple patches, along with the adhered skin, to retract towards the puncture site. Furthermore, the pressure can be released by controlling the multiple patches to reset without removing the bandage.

[0059] Furthermore, some puncture procedures require the replacement of sterile cotton or medication. This invention exposes the puncture site through the hollowed-out portion of the tension patch, and a removable medicated cap is installed in the hollowed-out portion of the tension patch to protect the puncture site, or to apply cotton to the puncture site, allowing for quick replacement of the cotton without removing the bandage.

[0060] Among them, the tension patch 1 includes a positioning ring 11, two outer connecting pieces 12 are provided on the outer side of the positioning ring 11, and multiple adhesive block assemblies 13 are slidably connected to the bottom end of the positioning ring 11.

[0061] The positioning ring 11 is connected to the binding member 2 through two external connecting pieces 12;

[0062] Among them, two outer connecting pieces 12 are symmetrically distributed on the outside of the positioning ring 11, and both outer connecting pieces 12 are rotatably connected to the positioning ring 11. The outer sides of the two outer connecting pieces 12 are used to connect the ends of the binding pieces 2.

[0063] In this configuration, multiple adhesive block components 13 are evenly distributed around the positioning ring 11, and each of the multiple adhesive block components 13 can extend and retract toward the center of the positioning ring 11.

[0064] The bottom end of the positioning ring 11 is provided with multiple sliding grooves 111 for sliding connection of each adhesive block assembly 13. Two transverse through holes 112 are provided on the outer side of the positioning ring 11, and the upper part of the inner side of the positioning ring 11 is provided with internal threads 113.

[0065] The adhesive block assembly 13 includes a sliding adhesive block 131 that is slidably connected in the slide groove 111. A telescopic adhesive block 132 is provided at one end of the sliding adhesive block 131 near the center of the positioning ring 11. A wire buckle 133 is provided at the top of the telescopic adhesive block 132.

[0066] The telescopic patch 132 is provided with a telescopic rod 1321 extending into the interior of the sliding patch 131, and a spring 1322 is sleeved on the telescopic rod 1321 inside the telescopic rod 1321. The spring 1322 can make the telescopic patch 132 tend to move closer to the sliding patch 131.

[0067] Since the inner side of the positioning ring 11 is hollow and multiple adhesive components 13 are attached to the inner side of the positioning ring 11 in the initial state, the inner empty area of ​​the positioning ring 11 is relatively large, which makes it easier to press the positioning ring against the outside of the puncture site.

[0068] When the positioning ring 11 is compressed, multiple adhesive block components 13 at its bottom end are adhered to the skin. Each adhesive block component 13 is independently slidably connected in the slide groove 111. Any one of the adhesive block components 13 is adhered to the skin through the sliding patch 131 and the telescopic patch 132. When the telescopic patch 132 is subjected to force and moves toward the center of the positioning ring 11, the telescopic patch 132, together with the telescopic rod 1321, compresses the spring 1322 inside the sliding patch 131. Therefore, when the telescopic patch 132 is stretched out under force, it will elastically pull the sliding patch 131 to move. The sliding patch 131 will exert a weaker pulling force on the outer skin, thereby reducing the pulling force on the skin outside the puncture site and effectively improving the comfort of using the device.

[0069] Among them, the gathering and pulling component 3 includes a rotating seat 31 fixedly connected to any of the outer connecting pieces 12, a knob 32 rotatably connected to the rotating seat 31, a thorn 33 provided on one side of the knob 32 on the rotating seat 31, and a rope loop 34 for being jointly fitted onto multiple wire buckles 133 wound around the knob 32.

[0070] The knob 32 can pull multiple wire buckles 133 together through the rope loop 34 by rotating on the rotating base 31. The two rope loops 34 can pull multiple wire buckles 133 together from two opposite directions, so that multiple sticky block components 13 can extend together toward the center of the positioning ring 11.

[0071] The knob 32 is fixedly connected to both ends of the rope loop 34. The knob 32 can be rotated on the rotating base 31 to synchronously wind the two ends of the rope loop 34.

[0072] The rotating base 31 has an upper slot 311 and a lower slot 312. The upper slot 311 is used to connect the thorn 33, and the lower slot 312 is used to allow the rope loop 34 on the knob 32 to pass through.

[0073] The rope loop 34 extends to the inside of the positioning ring 11 by passing through the wire hole 112.

[0074] The thorn 33 includes a torsion spring rod 331 longitudinally disposed in the upper slot 311, and a one-way locking block 332 rotatably connected to the torsion spring rod 331. The one-way locking block 332 has an external protrusion 333 on its outer side.

[0075] The torsion spring rod 331 enables the front end of the one-way latch 332 to elastically abut against the outside of the knob 32.

[0076] The outer side of the knob 32 is provided with a one-way toothed groove. When the knob 32 rotates clockwise on the rotating base 31, it engages with the front end of the one-way locking block 332. When the knob 32 rotates counterclockwise on the rotating base 31, it does not engage with the front end of the one-way locking block 332.

[0077] Two rope loops 34 are together fitted onto multiple wire buckles 133, and two symmetrically distributed gathering and pulling members 3 pull the two ends of the two rope loops 34 respectively, so that the outer side of the multiple wire buckles 133 can be evenly gathered. The wire buckles 133 are subjected to force and move together with the telescopic patch 132. The telescopic patch 132 slides in the slide groove 111 through the telescopic rod 1321 and the spring 1322 together with the sliding patch 131. Therefore, the multiple sliding patches 131 will slide synchronously in the multiple slide grooves 111 toward the center of the positioning ring 11, and pull the skin on the outside of the puncture site evenly in sequence.

[0078] When the knob 32 of the retracting member 3 pulls the rope loop 34, the one-way locking block 332 of the thorn member 33 will elastically abut against the one-way locking tooth on the outer side of the knob 32 under the action of the torsion spring rod 331. When the rope loop 34 is pulled, the knob 32 rotates counterclockwise. Therefore, the outer side of the knob 32 will not engage with the front end of the one-way locking block 332. When the knob 32 is released, the front end of the one-way locking block 332 engages with the outer side of the knob 32, thus preventing the knob 32 from rotating clockwise.

[0079] Alternatively, the one-way latch 332 can be moved by the external protrusion 333, thereby preventing the one-way latch 332 from engaging with the outer side of the knob 32.

[0080] The medicine cap 4 includes a protective cap 41, a screw 42, and a pressing component 43;

[0081] The bottom end of the protective cover 41 is threaded to the inside of the positioning ring 11, and the screw 42 is threaded to the center of the protective cover 41. The bottom end of the screw 42 extends to the inside of the protective cover 41 and is connected to the center of the back of the pressing member 43.

[0082] The outer periphery of the pressing member 43 is provided with a plurality of evenly distributed barbs 431. The front ends of the barbs 431 all extend obliquely toward the back of the pressing member 43. The center of the back of the pressing member 43 is rotatably connected to the bottom end of the screw 42 by a connector 432.

[0083] The pressing member 43 has a cotton wool 433 on its front side, and the pressing member 43 hooks the fibers of the cotton wool 433 through a plurality of hooks 431.

[0084] After the puncture site is compressed, the corresponding cotton wool 433 can be attached to the bottom of the pressing member 43, and the fibers on the outer periphery of the cotton wool 433 can be fastened to multiple hooks 431, thereby fixing the cotton wool 433 to the bottom of the pressing member 43. Then, the protective cover 41 is screwed into the internal thread 113 on the inner side of the positioning ring 11. Finally, the screw 42 is turned so that the screw moves spirally downward on the protective cover 41, and the cotton wool 433 at the bottom of the pressing member 43 is applied to the puncture site.

[0085] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
