Description

Technical Field

[0001] This utility model relates to the field of wristband technology, and in particular to a hemostatic wristband with a blood leakage alarm function. Background Technology

[0002] Uremic patients are prone to bleeding due to platelet adhesion dysfunction, coagulation abnormalities, and the use of anticoagulants during hemodialysis. Bleeding from the puncture site of the arteriovenous fistula is a common complication, and bleeding caused by needle slippage is a serious complication. Timely detection and treatment of bleeding are key measures to reduce blood loss during dialysis and avoid serious adverse consequences.

[0003] Hemostasis measures are used to prevent bleeding from the fistula puncture site, thus avoiding serious adverse consequences. For example, Chinese Patent Publication No. CN213465188U discloses a pressure-quantified hemostatic wristband for dialysis, belonging to the field of medical device technology. It includes a casing with hemostatic bands on both sides, a replaceable compression bladder on the lower surface of the casing, and a rubber-made inverted frustum-shaped sealed bladder structure. A connecting conduit is located inside the casing, and a vent is located on the lower surface of the casing. The first interface of the connecting conduit communicates with the inner cavity of the compression bladder through the vent. A control valve is located on one side of the casing, communicating with a second interface of the connecting conduit. A pressure sensor is located inside the casing, communicating with a third interface of the connecting conduit. A sound sensor and a processing and display unit are also located inside the casing. A miniature blood pressure sensor is located on the hemostatic bands. This invention is convenient and highly user-friendly for clinical operation, enabling objective quantitative indicators to guide the entire process of compression hemostasis and release. It is reusable, has stable performance, and easy to replace easily damaged components, thus protecting and extending the lifespan of the fistula.

[0004] In practice, external pressure is used to prevent bleeding from the puncture site. However, due to platelet adhesion dysfunction, coagulation abnormalities, or other conditions, bleeding from the puncture site can still occur. Therefore, it is not possible to apply external pressure to the patient for an extended period of time to stop the bleeding. Consequently, bleeding may not be detected or reported in a timely manner, which can easily cause harm to the patient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot detect and report bleeding in a timely manner, and to propose a hemostatic wristband with a bleeding alarm function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a hemostatic wristband with a bleeding alarm function, including an outer layer and a hemostatic layer. The outer layer is fixed to the fistula puncture site on the arm by a fixing structure on both sides. The fixing structure includes a pair of elastic wristbands, which are fixed together by a snap-fit ​​part at the free end, and an anti-dislodgement part to prevent accidental dislodgement.

[0008] The outer layer and the hemostatic layer are stacked together, and a sensing unit is provided between them. The outer layer and the hemostatic layer are detachably connected by a connecting structure.

[0009] Furthermore, the fixing structure also includes stepped grooves and annular portions. One of the elastic wristbands has an annular portion at its free end. The elastic wristband has several stepped grooves evenly distributed along its length in the middle. The other elastic wristband has a snap-fit ​​portion and an anti-detachment groove on its inner and outer sides at its free end, respectively.

[0010] Furthermore, the free end of one of the elastic wristbands passes through the annular portion so that the snap-fit ​​portion snaps into the stepped groove, and the snap-fit ​​portion has a T-shaped cross-section.

[0011] Furthermore, the anti-slip part is an elastic structure, which is sleeved and slidably connected to the periphery of one of the elastic wristbands through a central through groove. The anti-slip part is also sleeved in the anti-slip groove by stretching and deformation to tighten the pair of elastic wristbands.

[0012] Furthermore, the connection structure includes a first Velcro strap, an avoidance groove at one end of the outer layer, the outer layer being located on the outside of the other end, and the first Velcro straps being fixedly connected to both sides of the avoidance groove, wherein the sensing unit is placed between the outer layer and the hemostatic layer through the avoidance groove.

[0013] Furthermore, it also includes a second Velcro, the hemostatic layer is located at the lower end, and the left and right sides of the upper end are fixedly connected with the second Velcro, and the second Velcro at the upper and lower ends is bonded to the corresponding first Velcro.

[0014] In this case, a pair of second Velcro straps cover the clearance groove by bending.

[0015] The present invention proposes a hemostatic wristband with a blood leakage alarm function. The advantages are as follows: the present invention can conveniently and quickly fix the hemostatic wristband to the patient's arteriovenous fistula puncture site through a fixing structure. When the detection unit comes into contact with blood, it can immediately alarm the monitoring terminal to remind medical staff to deal with it in time. In addition, the pair of elastic wristbands can be adjusted in multiple positions to adapt to arms of different thicknesses within a certain range. Furthermore, since the hemostatic layer absorbs some blood during the hemostasis process, the connecting structure allows the hemostatic layer to be quickly disassembled after use, so that the outer layer can be disinfected and reused.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A hemostatic wristband with a bleeding alarm function includes an outer layer 1 and a hemostatic layer 2. The outer layer 1 is fixed to the fistula puncture site on both sides by a fixing structure 3. The fixing structure 3 includes a pair of elastic wristbands 31. The pair of elastic wristbands 31 are fixed together by a snap-fit ​​part 32 at the free end, and an anti-dislodgement part 33 prevents accidental dislodgement.

[0023] The outer layer 1 and the hemostatic layer 2 are stacked together, and a sensing unit 4 is provided between them. The outer layer 1 and the hemostatic layer 2 are detachably connected by a connecting structure 5.

[0024] In some embodiments, the outer layer 1 is a waterproof structure, which is integrally formed with the elastic wristbands 31 on both sides. The outer layer 1 and the hemostatic layer 2 are connected and fixed by the connecting structure 5. The hemostatic layer 2 comes into contact with blood during the hemostasis process and can be disassembled and replaced by the connecting structure 5. The outer layer 1 can be reused by disinfection.

[0025] Specifically, the hemostatic layer 2 can be made of medical hemostatic gauze and directly attached to the puncture hole of the fistula to achieve hemostasis.

[0026] Furthermore, the fixing structure 3 also includes stepped grooves 34 and annular portions 35. One of the elastic wristbands 31 has an annular portion 35 at its free end. The elastic wristband 31 has several stepped grooves 34 evenly distributed along its length in the middle. The other elastic wristband 31 has a snap-fit ​​portion 32 and an anti-detachment groove 36 on its inner and outer sides at its free end, respectively.

[0027] Furthermore, the free end of one of the elastic wristbands 31 passes through the annular portion 35 so that the snap-fit ​​portion 32 snaps into the stepped groove 34, and the snap-fit ​​portion 32 has a T-shaped cross-section.

[0028] More specifically, the anti-slip part 33 is an elastic structure, which is sleeved and slidably connected to the periphery of one of the elastic wristbands 31 through a central through groove. The anti-slip part 33 is also sleeved in the anti-slip groove 36 by stretching and deformation to tighten the pair of elastic wristbands 31.

[0029] In this embodiment, the specific structure of the fixing structure 3 can refer to the fixing structure of a wristwatch strap in the prior art;

[0030] In specific operation, the elastic wristband 31 and the anti-detachment part 33 are preferably made of materials with deformation capabilities such as rubber and silicone. One of the elastic wristbands 31 passes through the ring part 35 and is attached to the other elastic wristband 31. The snap-fit ​​part 32 is snapped into the stepped groove 34 to achieve the purpose of fixing the elastic wristbands 31 on both sides and tightening the hemostatic wristband. At this time, the hemostatic layer 2 is tightly attached to the puncture hole.

[0031] Specifically, the stepped groove 34 prevents the end protrusion of the locking part 32 from touching the patient's arm and causing discomfort;

[0032] Furthermore, the anti-slip part 33 is sleeved around one of the elastic wristbands 31 and the anti-slip groove 36 by stretching and deforming, and after restoring the deformation, it achieves the purpose of tightening a pair of elastic wristbands 31. At this time, the snap-fit ​​part 32 cannot easily disengage from the stepped groove 34, thus achieving the anti-slip function.

[0033] In general, the connection structure 5 includes a first Velcro 51, one end of the outer layer 1 is provided with an avoidance groove 11, the outer layer 1 is located on the outside of the other end, and the first Velcro 51 is fixedly connected to both sides of the avoidance groove 11. The sensing unit 4 is placed between the outer layer 1 and the hemostatic layer 2 through the avoidance groove 11.

[0034] Finally, it also includes a second Velcro 52. The hemostatic layer 2 is located at the lower end, and the left and right sides at the upper end are fixedly connected with the second Velcro 52. The second Velcro 52 at the upper and lower ends is bonded to the corresponding first Velcro 51.

[0035] In this case, a pair of second Velcro straps 52 cover the clearance groove 11 by bending.

[0036] It should be added that the sensing unit 4 is a blood oxygen monitoring probe or a water immersion sensor in the prior art. The sensor is electrically connected to monitoring equipment such as a monitor to detect and alarm the bleeding reaction.

[0037] It is worth mentioning that the first hook and loop fastener 51 and the second hook and loop fastener 52 are the adhesive side and the hook side, respectively, and they are connected and fixed to the outer layer 1 and the hemostatic layer 2 by mutual adhesion.

[0038] When the pair of second Velcro straps 52 are bent to cover the avoidance groove 11 and the elastic wristbands 31 on both sides are closed and tightened, they can cooperate with the human arm to close the openings on both sides between the outer layer 1 and the hemostatic layer 2, thereby achieving the function of stopping and fixing the sensing unit 4.

[0039] Of course, the detection surface of the sensing unit 4 needs to be set to face the hemostatic layer 2.

[0040] Working method: During operation, the sensing unit 4 is located between the outer layer 1 and the hemostatic layer 2 through the clearance groove 11, and the second Velcro 52 at the upper and lower ends are bonded to the corresponding first Velcro 51 to achieve the function of connecting and fixing the outer layer 1 and the hemostatic layer 2.

[0041] The hemostatic layer 2 is attached to the puncture site of the fistula. When the two elastic wristbands 31 are closed, they are used in conjunction with a pair of second Velcro straps 52 to fix the sensing unit 4. One of the elastic wristbands 31 passes through the annular part 35 and is attached to the other elastic wristband 31. The snap-fit ​​part 32 is snapped into the stepped groove 34. The anti-dislodgement part 33 is stretched and deformed and sleeved around one of the elastic wristbands 31 and the anti-dislodgement groove 36. After the deformation is restored, it achieves the purpose of tightening the pair of elastic wristbands 31. At this time, the snap-fit ​​part 32 cannot easily disengage from the stepped groove 34, thus achieving the anti-dislodgement function.

[0042] Finally, when bleeding occurs from the puncture, the hemostatic layer 2 plays a role in stopping the bleeding. When the amount of bleeding is large, the blood penetrates into the interior of the hemostatic layer 2. After the sensing unit 4 detects the blood, it issues an alarm to the monitoring equipment.
