Description

Technical Field

[0001] This utility model specifically relates to a local compression hemostatic and swelling-reducing cuff. Background Technology

[0002] After coronary angiography puncture, complications include bleeding and hematoma at the puncture site. Currently, the main clinical approach is to use gauze combined with elastic bandages to compress and stop the bleeding. To reduce swelling, an ice pack is wrapped with tape on the surface of the gauze or bandage and applied to the hematoma to reduce pain and swelling. However, this method is rather inconvenient.

[0003] In addition, the distance between the ice pack and the patient's skin in existing ice packs cannot be adjusted, and prolonged ice pack application may cause local numbness or tissue damage to the patient's skin. Furthermore, since the ice pack is fixed with tape, it is quite troublesome to remove.

[0004] To avoid prolonged pressure affecting blood circulation, the gauze or bandage needs to be loosened periodically. The pressure of re-wrapping the bandage after loosening it should be less than the pressure of the previous wrapping. However, it is difficult to determine the pressure of re-wrapping, and it can only be roughly determined by feeling, which is inconvenient.

[0005] Chinese patent CN202323268838.2, entitled "A Timed Hemostatic Compression Device for Puncture Wounds in Hemodialysis Patients," describes a device comprising a cold compress hemostatic sac, a tightening compression band, and a wristband buckle. The tightening compression band is sewn and fixed to the cold compress hemostatic sac, and the wristband buckle is fixedly installed on the tightening compression band. The cold compress hemostatic sac includes a hemostatic ice pack, a control panel, a drain port, a water inlet, a return spring, and a ball valve body. The tightening compression band is sewn and fixed to the hemostatic ice pack. A control panel is fixedly installed on the top. A drain port and a water inlet are respectively provided on both sides of the control panel. The drain port and the water inlet are fixedly installed on the hemostatic ice pack. A ball valve body is elastically installed inside the water inlet through a return spring. The wristband buckle includes a buckle body, a slide plate, a carrier plate, buckle teeth, and a spring. The buckle body is fixedly installed on the tightening compression belt. A slide plate is slidably installed on the buckle body. A carrier plate is fixedly installed on the slide plate. Several buckle teeth are fixedly installed on the carrier plate. The carrier plate is elastically connected to the buckle body through a spring.

[0006] As shown in the attached figure of patent CN202323268838.2, the technical solution of this patent injects a liquid medium into the cold compress hemostatic sac, uses the liquid medium to compress the puncture point to stop bleeding, and also uses the liquid medium to apply ice to the puncture point to reduce swelling. This solution can achieve the effects of compression hemostasis and swelling reduction, but the pressure cannot be adjusted, and it cannot solve the problem of skin discomfort caused by prolonged ice application.

[0007] In summary, there is a need for a device that allows for easy adjustment of the compression pressure, convenient fixation of the ice pack, and prevention of skin tissue damage from prolonged ice application. Utility Model Content

[0008] The technical problem to be solved by this utility model is that the pressure adjustment of existing compression swelling reduction devices is inconvenient and the skin tissue is easily damaged by prolonged ice application, as mentioned in the background art.

[0009] To address the aforementioned technical problems, a local compression hemostasis and swelling reduction cuff is proposed. This is achieved through the following technical solution: A local compression hemostasis and swelling reduction cuff includes a cuff body, a tension adjustment mechanism, an ice pack placement bag, and an ice application distance adjustment mechanism. The tension adjustment mechanism is disposed on the cuff body. The cuff body includes a fixing strap that passes through the tension adjustment mechanism to bind the cuff body to the patient's limb. The tightness of the fixing strap can be controlled and adjusted by the tension adjustment mechanism. The ice pack placement bag is disposed on the cuff body via the ice application distance adjustment mechanism, and an ice pack is placed inside the ice pack placement bag for cold compresses. The distance between the ice pack inside the ice pack placement bag and the patient can be controlled and adjusted by the ice application distance adjustment mechanism.

[0010] In a preferred embodiment of the present invention, the cuff body includes a strap storage compartment for storing the fixing strap. The fixing strap passes through the tension adjustment mechanism and is inserted into the strap storage compartment. The strap storage compartment facilitates the gathering of the fixing strap that passes through the tension adjustment mechanism, making it convenient to use.

[0011] In a preferred embodiment of the present invention, the fixing strap includes a support strip and an adjustment hole. The support strip is located at the upper edge of the fixing strap, and the adjustment hole is located on the surface of the fixing strap. The tension adjustment mechanism can cooperate with the adjustment hole to adjust the length of the fixing strap passing through the tension adjustment mechanism. The function of the support strip is to support the fixing strap, so that the fixing strap has a certain rigidity and facilitates the tightening of the fixing strap.

[0012] In a preferred embodiment of the present invention, a scale is provided on the support bar. The scale represents the length of the fixing strap passing through the tension adjustment mechanism. The scale facilitates the recording of pressure values, enables visual adjustment of pressure, and is easy to use.

[0013] In a preferred embodiment of the present invention, the tension adjustment mechanism includes a mounting box, adjusting rollers, and adjusting knobs. There are two adjusting rollers, which are spaced apart inside the mounting box. The fixing strap passes through the gap between the adjusting rollers and is inserted into the strap storage compartment in the cuff body. The adjusting knob is located on the adjusting rollers. Rotating the adjusting knob can adjust the length of the fixing strap passing through the tension adjustment mechanism. The tension adjustment mechanism facilitates the adjustment of the compression pressure, making it convenient and quick to use.

[0014] In a preferred embodiment of the present invention, an adjusting block is provided on the adjusting roller that cooperates with the adjusting hole on the fixing strap. When the adjusting roller rotates, the adjusting block drives the fixing strap to move. This arrangement facilitates the control of the movement of the fixing strap through the adjusting roller, thereby adjusting the pressure and making it convenient to use.

[0015] In a preferred embodiment of the present invention, a ratchet and pawl mechanism is provided on the adjusting roller connected to the adjusting knob. The ratchet and pawl mechanism can controllably limit the rotation direction of the adjusting roller. This arrangement ensures the stability of the fixing strap and the stability of its use.

[0016] In a preferred embodiment of the present invention, an unlocking block is provided on the pawl in the ratchet and pawl mechanism. The unlocking block cooperates with the adjustment knob. Pressing the adjustment knob can release the pawl's restriction on the ratchet in the ratchet and pawl mechanism with one click. This arrangement ensures the overall stability of the device.

[0017] In a preferred embodiment of the present invention, the ice pack distance adjustment mechanism includes an accordion-style inflatable bladder and an ice pack placement box. The accordion-style inflatable bladder is mounted on the cuff body. The ice pack placement box is connected to the accordion-style inflatable bladder and the ice pack placement bag. The ice pack for ice pack application passes through the placement opening on the ice pack placement bag and is placed in the ice pack placement box. The distance between the ice pack placement box and the patient's skin can be controlled and adjusted by inflating and deflating the accordion-style inflatable bladder. The ice pack distance adjustment mechanism facilitates the adjustment of the distance between the ice pack and the patient's skin by inflating and deflating the ice pack distance adjustment mechanism, preventing prolonged ice pack application from causing local numbness or tissue damage to the patient's skin, and is convenient to use.

[0018] In a preferred embodiment of the present invention, an airbag placement chamber is provided on the contact surface between the cuff body and the patient. The compression airbag used for point-to-point pressure hemostasis at the wound is placed in the airbag placement chamber. This arrangement facilitates point-to-point pressure on the wound and improves the hemostasis effect.

[0019] The advantages of this utility model compared with the prior art are:

[0020] The technical solution of this utility model uses a fixed strap that passes through the tension adjustment mechanism to bind the cuff body to the patient's limb. The tension adjustment mechanism and the fixed strap record a fixed pressure value. When adjusting the pressure, rotating the adjustment knob on the tension adjustment mechanism can achieve controllable adjustment of the pressure, which is convenient to use. Furthermore, the ice pack distance adjustment mechanism connects the cuff body and the ice pack placement bag. By inflating or deflating the ice pack distance adjustment mechanism, the distance between the ice pack and the patient's skin can be adjusted, preventing the problem of skin discomfort and tissue damage caused by prolonged close-range ice pack application. It is also convenient to use. Attached Figure Description

Detailed Implementation

[0033] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0034] like Figure 1 , 2As shown in Figure 3, a local compression hemostatic and anti-swelling cuff includes a cuff body 1, a compression airbag 2, a tension adjustment mechanism 3, an ice pack placement bag 4, and an ice application distance adjustment mechanism 5. The compression airbag 2 is located on the inner side of the cuff body 1 and is in direct contact with the patient. The tension adjustment mechanism 3 is located on the cuff body 1 and can adjust the pressure of the cuff body 1 on the patient. The ice pack placement bag 4 is connected to the cuff body 1 through the ice application distance adjustment mechanism 5, which can adjust the distance between the ice pack and the patient.

[0035] The main function of the cuff body 1 is to fix it on the patient's limb to achieve compression hemostasis. At the same time, the cuff body 1 also serves as a carrier for the tension adjustment mechanism 3, the ice pack distance adjustment mechanism 5, and the ice pack placement bag 4.

[0036] The main function of the compression airbag 2 is to apply pressure to the patient's limbs by inflating the compression airbag 2, thereby further enhancing the effect of compression hemostasis.

[0037] The main function of the tension adjustment mechanism 3 is to adjust the pressure of the cuff body 1 to prevent prolonged pressure from affecting blood circulation.

[0038] The main function of the ice pack holder 4 is to hold ice packs for ice application, making it convenient to use.

[0039] The function of the ice pack distance adjustment mechanism 5 is to adjust the distance between the ice pack placement bag 4 and the patient's skin, so as to prevent local numbness or tissue damage caused by prolonged ice application.

[0040] like Figure 1 , 2 As shown in Figure 3, the cuff body 1 is a cloth strip with a rectangular cross-section. In order to ensure the effect of use and improve the stability of use, the cuff body 1 is preferably made of breathable, deformation-resistant fabric that meets medical standards, such as polyester fiber and polyester. In this embodiment, polyester fiber material is preferred.

[0041] To facilitate fixing the cuff body 1 to the patient's limb, a fixing strap 11 is sewn at one end of the cuff body 1. The fixing strap 11 is made of the same material as the cuff body 1.

[0042] To improve the stability of the fixing strap 11, the fixing strap 11 is made of three layers of materials: two layers of fabric and one layer of rubber padding. The rubber padding is located in the middle of the fixing strap 11, and the polyester fiber fabric is located on the outside of the rubber padding. The three are fixed together by glue and heat pressing to prevent cracking.

[0043] To facilitate the fixation of the cuff body 1 using the fixing strap 11, rectangular grooves are provided on both the front and back sides of the fixing strap 11. These grooves are named adjustment holes 14. The adjustment holes 14 are evenly distributed in groups of three along the extension direction of the fixing strap 11. The fixing strap 11 can cooperate with the tension adjustment mechanism 3 through the adjustment holes 14 to adjust the tightness of the fixation, thereby adjusting the pressure on the patient.

[0044] Definition: In this embodiment, the working surface that comes into contact with the patient is the front side, and the other side is the back side.

[0045] To give the fixing strap 11 a certain rigidity and facilitate its tightening, a support strip 13 is glued to both sides of the fixing strap 11 near the edge. The support strip 13 is made of rubber and has a scale 15 printed on it. The support strip 13 can improve the rigidity of the fixing strap 11 and facilitate its tightening. The scale 15 is set to record the magnitude of the compression pressure during fixing, which is convenient for adjusting the compression pressure of the cuff body 1.

[0046] After the fixing strap 11 passes through the tension adjustment mechanism 3, to facilitate the storage of the fixing strap 11, a strap storage compartment 16 is integrally fixed to the cuff body 1 on the reverse side of the cuff body 1, near the tension adjustment mechanism 3. The strap storage compartment 16 is made of rubber and is rectangular in shape. A rectangular through hole is opened at one end of the strap storage compartment 16 near the tension adjustment mechanism 3. The fixing strap 11, after passing through the tension adjustment mechanism 3, can be inserted into the strap storage compartment 16. The effect after inserting the strap into the strap storage compartment 16 is as follows. Figure 10 As shown.

[0047] In order to improve the overall compression hemostasis effect of the device and achieve fixed-point compression, a rectangular groove is recessed perpendicular to the front of the cuff body 1 on the side that contacts the patient. This groove is named the airbag placement chamber 12. The compression airbag 2 used for fixed-point compression is fixed in the airbag placement chamber 12 with glue.

[0048] The compression airbag 2 is an existing inflatable airbag. On the reverse side of the cuff body 1, there is a compression airbag inflation hole 12 for inflating and deflating the compression airbag 2. Inserting the syringe into the compression airbag inflation hole 12 can inflate and deflate the compression airbag 2, thereby achieving fixed-point compression and improving the hemostasis effect.

[0049] like Figure 1 , 4As shown in Figures 5, 6, and 7, the tension adjustment mechanism 3 includes a mounting box 301, an adjusting roller 302, and an adjusting knob 303. The mounting box 301 is fixed to the other end of the cuff body 1 away from the fixing strap 11. The adjusting roller 302 is installed inside the mounting box 301. The adjusting knob 303 is connected to the adjusting roller 302. The fixing strap 11 passes through the mounting box 301. Rotating the adjusting knob 303 can drive the adjusting roller 302 to rotate. The adjusting roller 302 can drive the fixing strap 11 inserted in the mounting box 301 to move, thereby realizing the adjustment of pressure.

[0050] The mounting box 301 is a hollow plastic box with a rectangular cross-section. To facilitate the installation of the adjusting roller 302, one end of the mounting box 301 is open, and the opening is closed by a side plate 305. To facilitate the fastening strap 11 passing through the mounting box 301, elongated through holes are provided on the front and back of the mounting box 301, which are named functional holes 306. The fastening strap 11 passes through the mounting box 301 through the functional holes 306.

[0051] The adjusting roller 302 is a plastic roller with a circular cross-section. Circular mounting platforms protrude from both ends of the adjusting roller 302. The diameter of the mounting platforms is smaller than the diameter of the adjusting roller 302. The two ends of the mounting platforms are inserted into the mounting box 301, and the adjusting roller 302 can rotate freely along the insertion point.

[0052] Two adjusting rollers 302 are provided in the mounting box 301. The two adjusting rollers 302 are distributed in parallel in the mounting box 301, and there is a certain gap between them. The fixing strap 11 passes through the gap between the two adjusting rollers 302.

[0053] To facilitate the control of the movement of the fixing strap 11 via the adjusting roller 302, an adjusting block 307 with a rectangular cross-section protrudes perpendicularly outward from the arc surface of the adjusting roller 302. The size, spacing, and number of the adjusting block 307 correspond to those of the adjusting holes 14. When the adjusting roller 302 rotates, the adjusting block 307 can engage with the adjusting holes 14, similar to the engagement of gears, to drive the fixing strap 11 to move, thereby adjusting the tightness of the fixing strap 11. The longer the fixing strap 11 passes through the mounting box 301, the tighter the cuff body 1 is fixed, and the greater the pressure applied to the puncture site for hemostasis. Therefore, adjusting the tightness of the fixing strap 11 corresponds to the magnitude of the pressure applied to the puncture site for hemostasis.

[0054] To prevent the fixing strap 11 from loosening under pressure, a ratchet and pawl mechanism 304 is also provided on the adjusting roller 302 where the adjusting knob 303 is installed. The ratchet in the ratchet and pawl mechanism 304 is coaxially connected to the mounting platform on the adjusting roller 302. The ratchet moves synchronously with the adjusting roller 302. When the adjusting knob 303 is rotated counterclockwise (tightening the fixing strap 11), the ratchet moves normally. When the adjusting knob 303 is rotated in the opposite direction, the adjusting roller 302 is restricted by the pawl in the ratchet and pawl mechanism 304 and cannot rotate.

[0055] When it is necessary to loosen the ratchet, in order to facilitate the release of the ratchet's restriction on the ratchet, a rectangular unlocking block 309 protrudes outward on the ratchet. The side of the unlocking block 309 facing the adjustment knob 303 is arc-shaped, and the arc-shaped surface of the unlocking block 309 can fit against the surface of the adjustment knob 303. At the same time, a rectangular unlocking push button 313 is also connected to the unlocking block 309. Pushing the unlocking push button 313 can drive the ratchet to move and release the restriction.

[0056] For ease of operation, the adjustment knob 303 is designed to be pressable on the adjustment roller 302. That is, when the adjustment knob 303 is pressed, it can slide relative to the adjustment roller 302. This setting allows the adjustment knob 303 to press against the unlocking block 309 when the unlocking push button 313 is pushed to release the restriction, keeping the ratchet pawl in the unlocked state. At this time, the adjustment roller 302 can rotate freely.

[0057] A circular limiting ring 308 protrudes outward perpendicularly from the arc surface of the adjusting knob 303. At the same time, a limiting groove 312 that cooperates with the limiting ring 308 is also provided on the unlocking block 309. When the ratchet and pawl are always in the unlocked state, the limiting ring 308 and the limiting groove 312 cooperate to limit the ratchet and pawl, keeping them in the unlocked state for easy use.

[0058] To facilitate the movement of the adjustment knob 303 on the adjustment roller 302, a rectangular guide groove 310 is recessed on the arc-shaped surface of the mounting platform on the adjustment roller 302. At the same time, a guide block that cooperates with the guide groove 310 is also protruding on the inner side of the adjustment knob 303. The adjustment knob 303 moves along the guide groove 310 on the adjustment roller 302.

[0059] After the limiting ring 308 is released from its limiting position in conjunction with the limiting groove 312, a reset spring 311 is fixed at the connection between the adjusting knob 303 and the adjusting roller 302 to facilitate the reset of the adjusting knob 303. When the adjusting knob 303 is pressed, the reset spring 311 is compressed.

[0060] like Figure 1 , 8As shown in Figures 9 and 11, the ice pack distance adjustment mechanism 5 includes an accordion-style inflatable bladder 51 and an ice pack placement box 52. The accordion-style inflatable bladder 51 is made of rubber material and is bent into an accordion shape. The two ends of the accordion-style inflatable bladder 51 are open. One end is connected to a rectangular fixing piece 53, and the other end is connected to the ice pack placement box 52 to achieve a seal for the accordion-style inflatable bladder 51.

[0061] The fixing piece 53 is a soft pad made of rubber. Its main function is to fix the accordion-style airbag 51 to the surface of the cuff body 1. After the fixing piece 53 is connected to the accordion-style airbag 51, it is fixed to the surface of the cuff body 1 with glue.

[0062] The ice pack placement box 52 is a rectangular box made of flexible plastic. The upper end of the opening of the ice pack placement box 52 is connected to the accordion-style inflatable bladder 51. When the accordion-style inflatable bladder 51 is not inflated, the ice pack placement box 52 is in contact with the fixing plate 53.

[0063] To facilitate the inflation and deflation of the accordion-style airbag 51, an accordion airbag inflation port 54 is fixed on the reverse side of the cuff body 1, corresponding to the accordion-style airbag 51. Inserting a syringe into the accordion airbag inflation port 54 can inflate and deflate the accordion-style airbag 51. When the accordion-style airbag 51 is inflated, it will unfold, and the distance between the ice pack placement box 52 and the fixing plate 53 will increase, thereby adjusting the ice pack distance.

[0064] To facilitate the placement of ice packs, an ice pack placement bag 4 is glued to the ice pack placement box 52. The ice pack placement bag 4 is rectangular in shape and made of polyester fiber cloth. The ice pack placement bag 4 and the ice pack placement box 52 together form a chamber for placing ice packs.

[0065] A rectangular opening 41 is provided on the surface of the ice pack placement bag 4, and an ice pack containing ice is placed into the ice pack placement bag 4 through the opening 41.

[0066] The usage process of this embodiment is as follows: When using, first place the cuff body 1 on the patient's limb, then pass the fixing strap 11 through the tension adjustment mechanism 3, then inflate the compression airbag 2 so that the compression airbag 2 corresponds to the puncture point, then rotate the adjustment knob 303 to tighten the fixing strap 11, and after fixing, record the corresponding pressure through the scale 15 on the fixing strap 11.

[0067] When it is necessary to loosen the fixing strap 11 to prevent prolonged pressure from affecting blood flow, push the unlocking push button 313 and press the adjustment knob 303. At this time, the adjustment knob 303 can be rotated in the opposite direction to loosen the fixing strap 11 and relieve pressure. When it is necessary to readjust the fixing strap 11, push the unlocking push button 313. The adjustment knob 303 will reset under the action of the return spring 311. At this time, the adjustment knob 303 can only be tightened and not loosened. Then rotate the adjustment knob 303 to adjust the tightness of the fixing strap 11 to be slightly less than the pressure before loosening.

[0068] When ice packs are needed, first place the ice pack into the ice pack storage bag 4 through the placement opening 41, and then apply the ice pack. When it is necessary to adjust the distance between the ice pack and the patient for a long time, simply inflate the accordion-style air bag 51. After the accordion-style air bag 51 is inflated, it unfolds, and the distance between the ice pack and the patient's skin increases, thus completing the distance adjustment and preventing the patient's skin from becoming numb or the tissue from being damaged due to prolonged ice pack application. It is easy to use.

[0069] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
