[0001] This utility model relates to the field of medical device technology, and in particular to a pacemaker implantation site compression hemostasis and fixation device. Background Technology
[0002] The pacemaker implantation site compression hemostasis and fixation device is a medical auxiliary device designed specifically for patients after pacemaker implantation. It is mainly used to apply continuous and uniform pressure to the surgical incision and pacemaker implantation site to achieve hemostasis, fix the pacemaker body, reduce postoperative complications and promote wound healing. It can suppress capillary bleeding in the incision through controllable pressure, reduce the incidence of postoperative hematoma and reduce the risk of hematoma formation.
[0003] Traditional pacemaker implantation site compression hemostasis and fixation devices typically only have single functions of compression hemostasis and fixation, which cannot adapt to the dynamic changes in the user's post-pacemaker implantation care, resulting in poor therapeutic effects. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a pacemaker implantation site compression hemostasis and fixation device, which aims to improve the problem that the existing device has a single compression hemostasis function, which affects the treatment effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a pacemaker implantation site compression hemostasis and fixation device, comprising a front fixation strap, a water-filled bladder fixedly connected to the surface of the front fixation strap, a heating port installed on the top of the water-filled bladder, the interior of the water-filled bladder filled with polyethylene glycol solution, an air bladder fixedly connected to the inner wall of the water-filled bladder, a fixation layer fixedly connected to the front surface of the air bladder, a heating layer fixedly connected to the rear side of the air bladder, a buffer layer fixedly connected to the rear side of the heating layer, both the buffer layer and the heating layer being fixedly connected to the front fixation strap, a rear fixation strap fixedly connected to the right side of the front fixation strap, and a connecting mechanism provided on the left side of the front fixation strap.

[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the device achieves the hemostatic effect of compression through the airbag and the fixation layer. After the refrigerated polyethylene glycol solution is filled into the water bag, the cold compress effect is achieved through the buffer layer and the inner bonding layer.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-4 An embodiment of this utility model provides a pacemaker implantation site compression hemostasis and fixation device, including a front fixation band 1, a water bladder 3 fixedly connected to the surface of the front fixation band 1, a heating port 6 installed on the top of the water bladder 3, the inside of the water bladder 3 being filled with polyethylene glycol solution 20, an air bladder 2 fixedly connected to the inner wall of the water bladder 3, a fixation layer 13 fixedly connected to the front surface of the air bladder 2, a heating layer 16 fixedly connected to the rear side of the air bladder 2, a buffer layer 15 fixedly connected to the rear side of the heating layer 16, both the buffer layer 15 and the heating layer 16 being fixedly connected to the front fixation band 1, a rear fixation band 18 fixedly connected to the right side of the front fixation band 1, and a connecting mechanism provided on the left side of the front fixation band 1;
[0024] The airbag 2 is inflated in a controlled manner through the air valve 5. Since the fixation layer 13 is made of polypropylene, which has the characteristics of high strength and low ductility, it can ensure that the airbag 2 is only allowed to deform inward during inflation, avoiding the airbag 2 from expanding evenly on both sides. After the airbag 2 expands in a directional manner through the fixation layer 13, it continuously transmits stable pressure to the buffer layer 15 and acts on the implantation site, thereby keeping the pressure uniform during the device fixation process.
[0025] When applying a cold compress, the polyethylene glycol solution 20 can be injected through the inlet 4 after pre-cooling. The low temperature constricts local blood vessels, and the combination with the airbag compression can help reduce bleeding. When applying a hot compress, the heating layer 16 is activated through the heating port 6, which evenly transfers heat to the polyethylene glycol solution 20. The slow cooling properties of polyethylene glycol are used to keep the device warm, which promotes the absorption of blood stasis and tissue repair. This allows the device to provide phased intervention in the early postoperative anti-inflammatory stage and the mid-to-late postoperative rehabilitation stage.
[0026] Reference Figure 1 and Figure 4The connecting mechanism includes a second buckle 19, which is fixedly connected to the front fixing strap 1. A limiting post 11 is fixedly connected to the surface of the second buckle 19. A hook-shaped nylon hook 8 is fixedly connected to the left side of the rear fixing strap 18. The hook-shaped nylon hook 8 is engaged with a ring-shaped nylon hook 7. A limiting hole 12 is opened on the surface of the hook-shaped nylon hook 8. The limiting hole 12 is slidably connected to the limiting post 11.
[0027] The dense toothed engagement of the hook-shaped nylon hook-and-loop ...
[0028] Reference Figure 1 and Figure 4 The annular nylon hook and loop fastener 7 are fixedly connected to the surface of the front fixation strap 1, the hook-shaped nylon hook and loop fastener 19 are slidably connected, and the anti-dislodgement design of the limiting hole 12 and the limiting post 11 ensures that the device can maintain a stable fit with the user's body in different states such as bed rest, semi-recumbent position and light activity, thereby improving the reliability of postoperative fixation.
[0029] Reference Figure 2 The front fixation strap 1 has a buckle 9 fixedly connected to the top right side, and the rear fixation strap 18 has a hook-shaped nylon buckle 10 fixedly connected to the top right side. The vertical support force of buckle 9 can convert the shear force in the shoulder area into the horizontal compression force. Combined with the longitudinal adjustment of the bottom connecting mechanism, the entire device forms a stable three-point fixation plane in the infraclavicular fossa. The edge of buckle 9 is rounded and wrapped with silicone padding to avoid friction damage to the clavicle skin from the right-angle edge.
[0030] Reference Figure 3 An air valve 5 is installed on the surface of the airbag 2, and a pressure sensor 17 is installed on the surface of the heating layer 16. After the air valve 5 completes the initial inflation, the pressure sensor 17 enters the real-time monitoring state. When the pressure exceeds the safety threshold, the pressure sensor 17 sends an early warning signal to the medical terminal to avoid the risk of tissue ischemia caused by overpressure or blood accumulation in the airbag caused by underpressure.
[0031] Reference Figure 3An inner fitting layer 14 is fixedly connected to the rear side of the buffer layer 15. The inner fitting layer 14 is fixedly connected to the front fixing band 1. After contacting the human body, the buffer layer 15 can slowly deform according to the bony contour of the subclavian fossa, and evenly distribute the concentrated pressure transmitted by the airbag 2 to a larger area, so as to reduce the local skin pressure and effectively avoid ischemic damage to the epidermis caused by single-point pressure. Through the combined action of the buffer layer 15 and the inner fitting layer 14, the device can dynamically fit the chest rise and fall, reducing skin wrinkles and mechanical damage.
[0032] Reference Figure 1 The bottom of the water bladder 3 has a liquid inlet 4 for introducing polyethylene glycol solution 20 into the water bladder 3. The position of the liquid inlet 4 at the bottom of the water bladder 3 can realize the rapid filling and emptying of the solution by utilizing the principle of liquid gravity. When applying a cold compress, the pre-cooled polyethylene glycol solution 20 can be drawn with a syringe and injected into the water bladder 3 through the liquid inlet 4. When applying a hot compress, if it is necessary to replace the heated solution, the residual liquid can be discharged by opening the liquid inlet 4 using the siphon effect, avoiding the temperature drop caused by the mixing of hot and cold, and at the same time avoiding the impact of residual air bubbles on temperature conduction.
[0033] Reference Figure 3 The inner bonding layer 14 is made of silicone-coated non-woven fabric, and the buffer layer 15 is made of memory foam. The silicone coating is evenly covered on the surface of the non-woven fabric to form a breathable network, allowing the inner bonding layer 14 to allow water vapor on the skin surface to escape freely while blocking electrolytes and bacteria in sweat from penetrating into the device, thereby reducing the incidence of contact dermatitis when using the device.
[0034] When the airbag 2 applies pressure, the medical-grade memory foam in the buffer layer 15 can transform the linear pressure concentrated at the implantation site into a planar distribution, thereby reducing the local pressure at bony prominences such as the clavicle and manubrium of the sternum and effectively preventing pressure sores. At the same time, the thermosensitive properties of the memory foam allow the buffer layer 15 to soften faster during hot compresses, improving its fit and promoting the even conduction of heat to the skin. During cold compresses, the buffer layer 15 maintains appropriate rigidity, preventing the material from hardening due to low temperatures from affecting the compression effect, so that the device can maintain stable mechanical conduction efficiency in both hot and cold therapy modes.
[0035] Working principle: When using the device, gas is injected into the airbag 2 through the vent valve 5. After the airbag 2 is inflated, it expands in a directional manner through the fixing layer 13, so that the airbag 2 continuously provides pressure to the buffer layer 15, thereby achieving the compression hemostasis effect of the device.
[0036] When the user needs to use cold compresses for treatment, the refrigerated polyethylene glycol solution 20 is filled into the water bladder 3 through the liquid inlet 4. The temperature is transferred through the buffer layer 15 and the inner adhesive layer 14, so that the device can achieve the cold compress effect. When the device is used for cold compress, the low temperature can cause the user's local blood vessels to constrict, reducing bleeding and swelling. At the same time, the pressure of the air bladder 2 can further enhance the hemostatic effect.
[0037] When the user needs to use heat therapy for treatment, the heating layer 16 is heated by power supply through the heating port 6. The heating layer 16 transfers the temperature to the polyethylene glycol solution 20 and the buffer layer 15. The slow cooling characteristic of the polyethylene glycol solution 20 allows the device to maintain a high temperature for a long time, thereby realizing the heat therapy function of the device. Heat therapy can promote the user's blood circulation, accelerate the absorption of blood stasis and tissue repair, thus working together with the device's compression hemostasis function to improve the overall treatment effect.
[0038] Regarding the fixation of the device, the extension length of the hook-shaped nylon hook-8 can be adjusted by the limiting post 11 and the limiting hole 12. The front fixing strap 1 and the rear fixing strap 18 are fixed by the meshing connection between the hook-shaped nylon hook-8 and the buckle 9. This achieves a good fixing effect while allowing the device to be adjusted in size within a certain range to adapt to different user body sizes and improve the applicability of the device.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
