Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, in particular to a radial artery pressurizing device. Background Art
[0002] Radial artery pressure hemostasis is a method of long-term compression at the radial artery bleeding point to stop bleeding. The radial artery pressure time is usually six hours, and manual pressure is difficult to maintain the pressure continuously, which affects the hemostasis effect. Therefore, a pressure device needs to be fixed on the wrist to apply pressure to the radial artery bleeding point and maintain it continuously.
[0003] The radial artery pressurization device commonly used in clinical practice is usually a spiral pressurization structure, that is, a hard fixing plate is fixed to the wrist by a strapping structure such as a magic tape, and a threaded knob and a pressure plate are usually provided on the fixing plate. Manually turning the knob can push the pressure plate to apply pressure to the wrist. However, during the use of this pressurization device, in order to ensure the reliability of pressurization, the fixing plate is usually tightly tied to the wrist and in direct contact with the wrist skin. The edges and corners of the fixing plate will cause skin damage and even pressure sores when applying pressure to the wrist skin for a long time. In addition, during the long-term pressurization of the radial artery bleeding point, the edges of the pressure plate will also cause damage to the surrounding skin (the contact area of the edges and corners is small, which leads to increased pressure on the skin, thereby affecting the blood circulation of the skin tissue and causing skin tissue necrosis, and severe pressure sores can occur).
[0004] Therefore, during the pressurization process, the radial artery pressurization device commonly used in clinical practice cannot avoid direct contact between its edges and corners and the wrist skin, which may cause the wrist skin to be over-pressurized for a long time and thus be damaged.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] like Figure 1 and Figure 2 As shown, the utility model provides a radial artery pressurizing device, comprising:
[0033] An arched fixing plate 1 is formed with a pressure regulating screw hole 12, a pressure regulating screw rod 2 is arranged in the pressure regulating screw hole 12, the pressure regulating screw rod 2 is installed in the pressure regulating screw hole 12, and the end of the pressure regulating screw rod 2 passes through the pressure regulating screw hole 12 and is placed on the inner side of the arched fixing plate 1 and rotated to provide a pressure plate 21 for applying pressure to the radial artery of the wrist;
[0034] Both ends of the arched fixing plate 1 are provided with slots 13, and the outer side wall of the arched fixing plate 1 is provided with locking screw holes 14 penetrating into the slots 13, and the locking screw 3 is provided in the locking screw hole 14, and the end of the locking screw 3 passes through the locking screw hole 14 and is placed in the slot 13 and is rotatably provided with a locking pressure plate 31;
[0035] An isolation belt 4 is detachably provided between the two slots 13, and after the isolation belt 4 is inserted into the slot 13, the end of the isolation belt 4 can be pressed in the slot 13 by the locking screw 3 and the locking pressure plate 31, so that the isolation belt 4 wraps the end of the arched fixing plate 1;
[0036] Among them, magic bands 11 are set at both ends of the arched fixing plate 1. After the magic bands 11 tie the arched fixing plate 1 to the wrist, the isolation band 4 isolates the arched fixing plate 1 from the wrist skin, and isolates the pressure plate 21 from the wrist skin to prevent the wrist skin from being subjected to excessive pressure for a long time.
[0037] The pressurizer of this embodiment mainly utilizes the locking screws 3 and the locking pressure plate 31 at both ends of the arched fixing plate 1 to fix the two ends of the isolation belt 4 in the two slots 13 respectively, so that the isolation belt 4 is flattened on the inner side of the arched fixing plate 1, so that after the arched fixing plate 1 is tied to the wrist by the magic tape 11, the arched fixing plate 1 can be pressed on the isolation belt 4 without directly contacting the wrist skin, and after the pressure regulating screw 2 is rotated, when the pressure plate 21 is axially pushed to apply pressure to the radial artery of the wrist, the pressure plate 21 can also be pressed on the isolation belt 4 without directly contacting the wrist skin, and the isolation belt 4 is made of soft material, so as to avoid the hard arched fixing plate 1 and the pressure plate 21 directly applying pressure to the wrist skin for a long time and causing pressure sores.
[0038] Specifically, by using the isolation belt 4 to isolate the arched fixing plate 1 and the pressure plate 21 from the wrist skin, the pressure generated by the edges of the arched fixing plate 1 and the pressure plate 21 on the wrist skin is reduced while maintaining the pressure unchanged, thereby reducing the probability of pressure sores.
[0039] The isolation belt 4 is detachably installed in the slot 13 through the locking screw 3 and the locking pressure plate 31. Therefore, the isolation belt 4 can be freely replaced to ensure that pressing and stopping bleeding at the bleeding point of the radial artery is more hygienic.
[0040] Compared with the conventional pressurizer, the pressurizer of this embodiment can install an isolation belt 4 on the arched fixing plate 1, so that after the arched fixing plate 1 is fixed to the wrist by the magic tape 11, the isolation belt 4 can be attached to the skin of the wrist, and the edges and corners of the arched fixing plate 1 are pressed on the isolation belt 4, thereby preventing it from causing long-term overpressure on the wrist skin, and when the pressure plate 21 is pressed, the pressure plate 21 is also pressed on the isolation belt 4, thereby preventing it from causing long-term overpressure on the wrist skin, reducing the probability of pressure sores during the use of the pressurizer.
[0041] In order to ensure that the isolation strip 4 is firmly fixed to the arched fixing plate 1, the following preferred embodiments are provided.
[0042] like Figure 3 As shown, the isolation belt 4 includes a composite section 41 and two rough surface sections 42, and the composite section 41 is located in the middle of the isolation belt 4, and the two rough surface sections 42 are located at both ends of the isolation belt 4;
[0043] After the isolation tape 4 is installed in the two slots 13 , the composite section 41 is located between the notches of the two slots 13 , and the thickness of the composite section is greater than the thickness of the rough surface section 42 .
[0044] Specifically, the rough surface segment 42 is located at both ends of the composite segment 41, and the rough surface segment 42 is inserted into the slot 13. After the locking screw 3 pushes the locking pressure plate 31 onto the rough surface segment 42, when the two ends of the isolation belt 4 are subjected to tension (that is, the composite segment 41 is bent by the wrist pressure), the rough surface segment 42 and the locking pressure plate 31 can provide sufficient friction to prevent the isolation belt 4 from falling out.
[0045] The composite section 41 is used to isolate the wrist skin from the arched fixing plate 1 and the pressure plate 21. The composite section 41 is required to ensure hygiene while reducing the pressure of the arched fixing plate 1 and the pressure plate 21 on the skin. Therefore, the following preferred embodiments are provided.
[0046] like Figure 3 As shown, the composite section 41 includes a soft material layer 411, a smooth surface layer 412 and a dressing layer 413;
[0047] The two ends of the soft material layer 411 are sutured and connected to the rough surface section 42, the smooth surface layer 412 is bonded and fixed on the outer surface of the soft material layer 411, and the dressing layer 413 is detachably attached to the outer surface of the smooth surface layer 412;
[0048] The dressing layer 413 is used to contact the wrist skin.
[0049] Specifically, the soft material layer 411 of the composite segment 41 can be sutured and connected to the rough surface segment 42 , so that the soft material layer 411 and the rough surface segments 42 at both ends form a whole.
[0050] The smooth layer 412 can facilitate the sticking of the dressing layer 413, so that the dressing layer 413 can be freely replaced, so that the soft material layer 411 and the smooth layer 412 of the rough surface section 42 and the composite section 41 can be reused to reduce waste.
[0051] The dressing layer 413 may be a commonly used medical dressing patch with the same cutting specifications.
[0052] In order to further improve the isolation protection capability of the isolation zone 4, Figure 3 As shown, a thickening pad 414 is provided on the side of the soft material layer 411 facing the arched fixing plate 1 , and the thickening pad 414 is aligned with the pressure plate 21 .
[0053] Specifically, the thickened pad 414 is aligned with the pressure plate 21, and the pressure plate 21 can press on the thickened pad 414 to stop bleeding at the radial artery bleeding point, while ensuring that the pressure remains unchanged, reducing the regional pressure, thereby avoiding excessive pressure on the radial artery bleeding point and causing congestion.
[0054] Since the isolation belt 4 is installed on the inner side of the arched fixing plate 1, after the arched fixing plate 1 is fixed to the wrist by the magic belt 11, the isolation belt 4 is tightly wrapped around the wrist.
[0055] At this time, during the pressure application process of the pressure regulating screw 2 and the pressure plate 21 , the arched fixing plate 1 is moved away from the wrist by the reaction force, thereby generating a pulling force between the isolation belt 4 and the arched fixing plate 1 .
[0056] Therefore, in order to prevent the isolation belt 4 from coming out due to excessive tension, the following preferred embodiments are further provided.
[0057] like Figure 4 As shown, a plurality of ridges 311 are formed on a surface of the locking plate 31 away from the locking screw 3, and the ridges 311 are perpendicular to the insertion direction of the isolation belt 4;
[0058] A plurality of grooves 131 are formed on the groove wall of the slot 13 facing the locking plate 31 , and the plurality of ridges 311 can press the ends of the isolation belt 4 into the plurality of grooves 131 .
[0059] Specifically, a ridge 311 is formed on the surface of the locking pressure plate 31, and a groove 131 is formed on the inner wall of the slot 13. After the locking pressure plate 31 presses the rough surface segment 42 of the isolation belt 4, the rough surface segment 42 will be squeezed by the ridge 311 and the groove 131 to form a wavy shape, thereby increasing the friction resistance of the rough surface segment 42 and further preventing the rough surface segment 42 from being forced out.
[0060] It is worth noting that, in order to facilitate operation, the outer ends of the pressure regulating screw 2 and the locking screw 3 are both provided with knob caps.
[0061] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
