Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and in particular relates to a hemostatic pressure patch for hemodialysis. Background Technology

[0002] Hemodialysis patients need to undergo upper limb arteriovenous fistula shunting to ensure sufficient hemodialysis flow for removing toxins from the body. After the fistula is created, the blood vessel needs to be pressurized for hemostasis. The duration of pressurization varies depending on the patient's vascular condition or coagulation function (ranging from 30 minutes to several hours), and it needs to be intermittently released to protect the blood vessel.

[0003] Chinese patent announcement number CN218338488U discloses a radial artery timed pressure hemostat, including a base plate and a fixing strap. The base plate has a timer, which includes an alarm and a timer switch. The opposite ends of the base plate are fixedly connected to the ends of the fixing strap. A pressure plate and an elastic baffle are located on the inward-facing side of the base plate. An adjustment mechanism is provided on the base plate. The operator can preset the usage time of this device using the timer switch. After the preset time is reached, the alarm will sound to remind the operator, preventing the hemostat from being used for too long. In actual use, the adjustment mechanism can be used to adjust the pressure applied by the pressure plate to the hemostatic site, improving the hemostatic effect. The elastic baffle deforms elastically during use, abutting against the wrist, improving comfort and providing an anti-slip effect to prevent slippage during use, thus improving the hemostatic effect. The elastic baffle is preferably made of rubber.

[0004] However, this device has the following drawbacks: The pressure knob has external threads. While turning the knob applies pressure to the hemostatic site, the knob may come into contact with external objects while the patient is wearing the device, forcing it to turn and causing the pressure plate to loosen, leading to pressure failure. To address these drawbacks, we propose a hemostatic pressure patch for hemodialysis. Utility Model Content

[0005] The purpose of this utility model is to provide a hemostatic pressure patch for hemodialysis to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A hemodialysis hemostatic pressure patch, comprising:

[0007] The fastener includes a fixing plate, and a first restraining strap and a second restraining strap respectively disposed on both sides of the fixing plate. The fixing plate is composed of an assembly ring and a support plate fixedly installed at the lower end of the assembly ring.

[0008] A compression hemostasis structure, comprising a cylinder fixedly installed on the inner wall of an assembly ring, a compression component disposed inside the cylinder, and a hemostatic sponge placed on the inner wall of the cylinder.

[0009] The compression assembly includes a rotating cylinder rotatably mounted on the inner wall of the cylinder body, a nut seat fixedly mounted on the inner wall of the rotating cylinder, a threaded rod threadedly connected to the inner wall of the nut seat, a compression plate fixedly mounted on the lower end of the threaded rod, a guide component disposed on the surface of the compression plate, and a limiting component disposed between the rotating cylinder and the cylinder body.

[0010] Preferably, the guiding component includes a guide block fixedly mounted on the surface of the pressure plate and a guide groove formed in the inner wall of the cylinder.

[0011] Preferably, the limiting component includes a limiting ring fixedly installed on the upper end of the cylinder, a knob disposed on the outer surface of the rotating cylinder, a plurality of limiting blocks fixedly installed on the surface of the knob in a circumferential array, and a limiting groove formed on the inner ring surface of the limiting ring.

[0012] Preferably, the limiting groove allows the insertion of the limiting block.

[0013] Preferably, a strip block is fixedly installed on the inner wall of the knob, and a strip groove is provided on the surface of the rotating cylinder for the strip block to slide.

[0014] Preferably, the inner wall of the rotating cylinder is provided with a cavity for the threaded rod to move.

[0017] The hemostatic pressure patch for hemodialysis of this utility model has the following advantages:

[0018] 1. This hemodialysis hemostatic pressure patch, by setting a compression hemostatic structure and a fixator, the fixator is worn on the patient's hemostatic position. At this time, the hemostatic sponge is in the hemostatic position. Then, pulling the knob upward drives the limiting block to disengage from the limiting groove. Then, turning the knob drives the nut seat to rotate. The screw transmission between the nut seat and the threaded rod can drive the compression plate to squeeze the hemostatic sponge to compress and stop the hemostasis at the hemostatic position. Then, pushing the knob into the limiting ring, the limiting groove can cooperate with the limiting block to limit the knob, thereby avoiding the defect of the compression plate loosening due to the knob contacting the external object and rotating.

[0019] 2. This type of hemodialysis hemostatic pressure patch, by setting up a cylinder, allows the hemostatic sponge to be removed from the cylinder after hemostasis is completed, while retaining the fixator and compression hemostatic structure. After the next hemodialysis session, the hemostatic sponge can be replaced and placed back into the cylinder for hemostasis, thus saving patients replacement costs. Attached Figure Description

[0030] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed description of a hemodialysis hemostatic pressure patch.

[0031] like Figure 1-3 As shown, this utility model provides a hemostatic pressure patch for hemodialysis, comprising: a fixator and a pressure hemostatic structure.

[0032] The fastener includes a fixing plate, and a first binding strap 10 and a second binding strap 11 respectively disposed on both sides of the fixing plate. The fixing plate is composed of an assembly ring 12 and a support plate 13 fixedly installed at the lower end of the assembly ring 12. The upper surface of the support plate 13 is provided with an assembly button 70, and both ends of the first binding strap 10 and the second binding strap 11 are provided with assembly eyelets 71. The opposite sides of the first binding strap 10 and the second binding strap 11 are respectively provided with matching adjustment buttons 72 and adjustment eyelets 73.

[0033] There are multiple adjustment eyelets 73. Depending on the diameter of the patient's arm, the adjustment button 72 can be fastened into the adjustment eyelets 73 at different positions, and the assembly button 70 can be fastened into the assembly eyelet 71. Thus, the device can be fixed to the patient's hemostasis position using the first restraint strap 10 and the second restraint strap 11.

[0034] The compression hemostasis structure includes a cylinder 20 fixedly installed on the inner wall of the assembly ring 12, a compression component disposed inside the cylinder 20, and a hemostatic sponge 21 placed on the inner wall of the cylinder 20. The hemostatic sponge 21 is placed inside the cylinder 20, thereby limiting the position of the hemostatic sponge 21.

[0035] The compression assembly includes a rotating cylinder 30 rotatably mounted on the inner wall of the cylinder 20, a nut seat 31 fixedly mounted on the inner wall of the rotating cylinder 30, a threaded rod 32 threadedly connected to the inner wall of the nut seat 31, a compression plate 33 fixedly mounted on the lower end of the threaded rod 32, a guide component disposed on the surface of the compression plate 33, and a limiting component disposed between the rotating cylinder 30 and the cylinder 20. The inner wall of the rotating cylinder 30 is provided with a cavity for the threaded rod 32 to move.

[0036] The guiding component includes a guide block 40 fixedly mounted on the surface of the pressure plate 33 and a guide groove 41 formed on the inner wall of the cylinder 20. By sliding the guide block 40 along the inner wall of the guide groove 41, the movement trajectory of the guide block 40 can be guided to prevent the pressure plate 33 from rotating.

[0037] The limiting component includes a limiting ring 50 fixedly installed on the upper end of the cylinder 20, a knob 51 set on the outer surface of the rotating cylinder 30, a plurality of limiting blocks 52 fixedly installed in a circumferential array on the surface of the knob 51, and a limiting groove opened on the inner ring surface of the limiting ring 50. The limiting groove allows the limiting blocks 52 to be inserted. When the limiting blocks 52 are inserted into the limiting groove, the knob 51 can be limited to prevent it from rotating.

[0038] A strip block 60 is fixedly installed on the inner wall of the knob 51. A strip groove 61 for the strip block 60 to slide is opened on the surface of the rotating cylinder 30. When the limiting block 52 is inserted into the limiting groove, the strip block 60 can restrict the rotation of the rotating cylinder 30. When the limiting block 52 is disengaged from the limiting groove, the knob 51 is turned. At this time, the rotating cylinder 30 can be driven to rotate by the cooperation of the strip groove 61 and the strip block 60.

[0039] After the fixation device is worn on the patient's hemostatic position, the hemostatic sponge 21 is in the hemostatic position. Then, pull the knob 51 upward to drive the limiting block 52 out of the limiting groove. Then, turn the knob 51 to drive the nut seat 31 to rotate. The screw drive between the nut seat 31 and the threaded rod 32 can drive the pressure plate 33 to squeeze the hemostatic sponge 21 to compress and stop the hemostasis at the hemostatic position. Then, push the knob 51 into the limiting ring 50. The limiting groove can cooperate with the limiting block 52 to limit the knob 51, thereby avoiding the defect that the knob 51 will come into contact with external objects and cause it to rotate, resulting in the pressure plate 33 becoming loose.

[0040] Once hemostasis is achieved, the hemostatic sponge 21 can be removed from the cylinder 20, while retaining the fixator and compression hemostasis structure. After the next hemodialysis session, the hemostatic sponge 21 can be replaced and placed back into the cylinder 20 for hemostasis, thus saving the patient replacement costs.

[0041] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
