Description

Technical Field

[0001] The utility model relates to a hemostatic device, in particular to an interventional hemostatic device for cardiology, belonging to the technical field of medical devices. Background Art

[0002] At present, angiography and intravascular catheter intervention are generally used for the diagnosis and treatment of cardiovascular diseases. Interventional treatment is a minimally invasive treatment performed using modern scientific and technological means. Interventional treatment has the characteristics of no surgery, less trauma, quick recovery and good effect. When the treatment is over, the catheter needs to be removed and then the wound needs to be hemostatic. Reasonable pressure helps to stop bleeding. Generally, artificial fingers and palms are used to press the surgical incision site for compression and hemostasis. Due to long-term local pressure of fingers, the physical consumption and labor intensity of medical staff increase. Any negligence and lack of responsibility may cause the pressure point to shift, resulting in hemostasis failure, and easy to cause cross-infection of the hemostasis site. Therefore, special hemostasis devices are often used to assist in compression and hemostasis.

[0003] In the prior art, there is a hemostatic device for post-catheter interventional cardiology surgery disclosed in announcement number CN215994129U, which includes a compression pad, a bandage, and an airway tube. The compression pad is fixed above the patient's wound by the bandage, and the compression pad is fixed to the patient's wound by the bandage, so that the circular compression body and the annular compression body are closely attached to the patient's skin, and then the screw is driven to rotate by rotating the torsion body, thereby driving the gear disk to rotate, and then driving the driving column to move downward, thereby driving the circular compression body and the annular compression body to move and press down the patient's wound, and at the same time, the driving column drives the piston to cooperate with the shell to continuously extract air from the annular groove from the airway tube, so that the annular compression body tightly absorbs the patient's skin, and at the same time, the driving column drives the belt shaft to rotate and wrap the bandage around, thereby strengthening the compression of the patient by the hemostatic device. The wound effect is improved, and the hemostatic device is not slipped and the pressure point is not offset. Although the existing device also fixes the device on the patient's wound site by a strap, it takes a long time to press when stopping bleeding, so the strap needs to be tied to the patient's wound site for a long time, which is easy to cause nerve and blood vessel damage at the binding site and bring great discomfort to the patient. Secondly, the existing device can only provide downward pressure on the wound site, but when pressing, the wound site and the surrounding areas of the wound are pressed with greater force, resulting in a larger pressing area, which is easy to cause damage to local skin, muscles, tendons, and subcutaneous capillaries, and when pressing downward on the wound, it is easy to cause the wound to rupture, which is also not conducive to the smooth progress of hemostasis.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a pressing plate, a binding belt and a pressing hemostasis component. The pressing plate can be placed on the wound bleeding site of the patient's interventional cardiology surgery, and the pressing hemostasis component can be closely attached to the wound site. The two ends of the pressing plate are tied and fixed to the patient's body by the binding belt, so that the pressing hemostasis component can form a pressing action on the wound site, thereby achieving a better hemostasis effect.

[0017] 2. The center of the lower plate surface of the pressing plate provided in the utility model is movably connected with a movable inner shell, and the bottom surface of the movable inner shell is provided with a stepped downward pressure surface. The lower plate surface of the pressing plate is also connected with a plurality of elastic inclined push rods. When the pressing plate applies downward pressure to the pressing hemostasis component, the stepped downward pressure surface provided on the bottom surface of the movable inner shell contacts the pressing hemostasis component, thereby forming a stepped downward pressure surface for the pressing hemostasis component, so that a larger downward pressure can be applied to the center of the patient's wound, while the downward pressure applied to the periphery of the patient's wound is weakened in turn, thereby forming pressing with different downward pressures on the wound site, so as to ensure that the wound can be healed. While providing sufficient pressing force to stop bleeding at the middle part of the wound, it can also minimize excessive pressing on the peripheral part of the wound, and when the pressing plate presses down on the pressing hemostasis component, the pressing hemostasis component can push the movable inner shell upward and move a certain distance. At this time, the elastic oblique push rod will also be further bent due to the pressure on the pressing hemostasis component, that is, the elastic oblique push rod can have an inward pushing force on the pressing hemostasis component, which can act on the patient's wound so that the pressing hemostasis component can press the wound and also have an inward clamping and gathering effect on the wound, which can also have a certain hemostasis effect on the wound;

[0018] 3. The inner side of the bandage provided by the utility model is connected to two belt-shaped airbags. Inflating the belt-shaped airbags by means of the valve core can further tighten the bandage body, that is, the binding and fixation can be more firmly achieved, and the belt-shaped airbags can have a certain deformation ability. Therefore, when the patient's body moves, for example, when the patient needs to sit up or turn over, the contact part between the bandage and the patient's body can be slightly adjusted, which will not cause great discomfort to the patient. Secondly, since the inner side of each bandage is connected to two belt-shaped airbags, one of the belt-shaped airbags on the bandage can be inflated through the valve core separately, and after a period of time, the other belt-shaped airbag can also be inflated through the valve core, and at the same time, the initially inflated belt-shaped airbag can be deflated through the valve core, that is, the part that is pressed and fixed on the patient's body can be adjusted, so as to avoid long-term compression of the same part of the patient's body causing nerve and blood vessel damage in that part.

DETAILED DESCRIPTION

[0029] 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.

[0030] Embodiment 1

[0031] like Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, a cardiology interventional hemostasis device comprises a pressing plate 1, a binding belt 2 and a pressing hemostasis component 3. The binding belt 2 is movably connected to the two ends of the pressing plate 1. The pressing hemostasis component 3 is arranged at the center of the lower plate surface of the pressing plate 1. The pressing plate 1 can be placed on the wound bleeding site of the patient's cardiology interventional surgery, and the pressing hemostasis component 3 is closely attached to the wound site. The two ends of the pressing plate 1 are tied and fixed to the patient's body by the binding belt 2, so that the pressing hemostasis component 3 can form a pressing action on the wound site, thereby achieving a better hemostasis effect.

[0032] A movable inner shell 14 is movably connected to the center of the lower plate surface of the pressing plate 1, and a stepped downward pressure surface 16 is arranged on the bottom surface of the movable inner shell 14. A plurality of elastic inclined push rods 18 are also connected to the lower plate surface of the pressing plate 1, and the bottom ends of the elastic inclined push rods 18 are all inclined inwardly, and the bottom ends of the elastic inclined push rods 18 are against the pressing hemostasis component 3. When downward pressure is applied to the pressing hemostasis component 3 through the pressing plate 1, the stepped downward pressure surface 16 arranged on the bottom surface of the movable inner shell 14 contacts the pressing hemostasis component 3, thereby forming a stepped downward pressure surface for the pressing hemostasis component 3, so that a larger downward pressure can be applied to the center of the patient's wound, while the downward pressure applied to the periphery of the patient's wound is weakened successively, forming different pressures on the wound site. The downward pressure is applied to ensure that sufficient pressure to stop bleeding can be provided to the middle part of the wound while minimizing excessive pressure on the peripheral part of the wound. When the pressing plate 1 presses down on the pressing hemostatic component 3, the pressing hemostatic component 3 can push the movable inner shell 14 upward for a certain distance. At this time, the elastic inclined push rod 18 will be further bent due to the pressure on the pressing hemostatic component 3, that is, the elastic inclined push rod 18 can have an inward pushing force on the pressing hemostatic component 3, which can act on the patient's wound so that the pressing hemostatic component 3 can press the wound while also having an inward clamping and gathering effect on the wound, which can also have a certain hemostatic effect on the wound.

[0033] The inner side of each strap 2 is connected to two belt-shaped airbags 21, which are arranged in parallel on the belt body of the strap 2, and each belt-shaped airbag 21 is connected to a valve core 23. After the two ends of the pressure plate 1 are tied and fixed to the patient's body by the strap 2, the belt body of the strap 2 can be further tightened by inflating the belt-shaped airbags 21 through the valve core 23, that is, the binding and fixing can be more firmly achieved, and the belt-shaped airbags 21 can have a certain deformation ability, so when the patient's body moves, for example, when the patient needs to sit up or turn over, the contact part between the strap 2 and the patient's body can be made The position can be slightly adjusted without causing great discomfort to the patient. Secondly, since the inner side of each strap 2 is connected to two belt-like airbags 21, one of the belt-like airbags 21 on the strap 2 can be inflated through the valve core 23 separately, and after a period of time, the other belt-like airbag can also be inflated through the valve core 23. At the same time, the initially inflated belt-like airbag 21 is deflated through the valve core 23, that is, the part that is pressed and fixed on the patient's body can be adjusted to avoid long-term compression of the same part of the patient's body causing nerve and blood vessel damage in that part.

[0034] Embodiment 2

[0035] Improvements based on Example 1:

[0036] like Figures 1 to 7 As shown, two sets of binding rods 12 are fixedly connected to the two ends of the upper plate surface of the pressure plate 1, and the movable ends of the binding straps 2 are respectively passed around the rod bodies of the binding rods 12. The binding straps 2 can be combined and connected with the pressure plate 1 by passing the movable ends of the binding straps 2 through the rod bodies of the binding rods 12 and folding them outwards and sticking them together.

[0037] Furthermore, a square Velcro 24 and a square Velcro 25 are fixedly connected to the outer side of the strap 2 at the movable end thereof, and the connection positions of the square Velcro 24 and the square Velcro 25 are arranged in sequence in an upper and lower distribution on the outer side of the strap 2. The square Velcro 24 and the square Velcro 25 can make the strap 2 and the pressure plate 1 more firmly connected under the adhesive action of the square Velcro 24 and the square Velcro 25, that is, they can form a binding for the patient's body, and the length of the movable end of the strap 2 that is wrapped around the rod 12 can be adjusted, that is, a more secure binding can be ensured.

[0038] Furthermore, belt body limiting inclined surfaces 13 are provided on both sides of the plate body of the pressure plate 1, and the movable end of the belt body of the strap 2 is clamped on the belt body limiting inclined surface 13. The belt body limiting inclined surface 13 can prevent the belt body of the strap 2 from directly contacting the right-angled side of the pressure plate 1, thereby preventing wear on the belt body of the strap 2. In addition, the belt body limiting inclined surface 13 can form a limiting and clamping effect on the belt body of the strap 2, thereby ensuring that the binding part of the strap 2 can provide maximum downward pressure on the pressure plate 1.

[0039] Furthermore, the limiting outer shell 11 is fixedly connected to the center of the upper plate surface of the pressure plate 1, and the movable inner shell 14 is movably sleeved in the limiting outer shell 11. A compression spring 15 is arranged in the limiting outer shell 11, and the upper end of the compression spring 15 is fixedly connected to the top inner wall of the limiting outer shell 11, and the lower end of the compression spring 15 is fixedly connected to the bottom inner wall of the movable inner shell 14. The movable inner shell 14 and the limiting outer shell 11 can be combined and connected together through the connection of the compression spring 15. During the pressing process of the pressure plate 1, the elastic force of the compression spring 15 on the movable inner shell 14 can form a downward pressure on the pressing hemostasis component 3, and when the movable inner shell 14 is completely moved into the limiting outer shell 11, the pressure plate 1 can directly press down the movable inner shell 14, thereby providing a greater downward pressure action on the pressing hemostasis component 3.

[0040] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, a movable cover piece 22 is connected to the outer side of the body of the strap 2, and a valve core 23 is located on the outer side of the body of the strap 2, and the connection position of the valve core 23 on the body of the strap 2 is located at the shielding position of the movable cover piece 22, so that when the strap 2 is tied to the patient's body, the valve core 23 is arranged on the outer side of the body of the strap 2 to facilitate the introduction of gas into the belt-shaped airbag 21, and the movable cover piece 22 can form a shielding for the valve core 23, which can prevent the patient's arms and other parts from touching the valve core 23 to cause damage to the arms and other parts, or foreign objects from entering the valve core 23 to cause blockage of the valve core 23.

[0041] Furthermore, the movable cover piece 22 is attached to one side of the belt body of the strap 2 and is fixedly connected with a frame-shaped Velcro 26, and the outer belt body of the strap 2 is fixedly connected with a frame-shaped Velcro mother patch 27, and the frame-shaped Velcro 26 and the frame-shaped Velcro mother patch 27 are arranged in a corresponding shape, and the movable cover piece 22 and the strap 2 can be firmly connected and combined together through the bonding action of the frame-shaped Velcro 26 and the frame-shaped Velcro mother patch 27, thereby preventing the movable cover piece 22 from loosening.

[0042] Furthermore, the pressing hemostasis component 3 includes an antibacterial care pad 31 and a hemostatic cotton pad 32, and the antibacterial care pad 31 and the hemostatic cotton pad 32 are stacked and arranged in an upper and lower distribution, so that when the hemostasis component 3 is pressed to stop bleeding on the patient's wound, the hemostatic cotton pad 32 can be tightly attached to the wound to achieve a better hemostatic effect. At the same time, during the hemostasis process, the antibacterial care pad 31 can isolate and inhibit bacteria on the wound site to prevent wound infection.

[0043] Working principle: The compression plate 1 is placed on the wound bleeding site of the patient's interventional cardiology surgery, and the compression hemostasis component 3 is placed close to the wound site. The two ends of the compression plate 1 are tied and fixed to the patient's body by the strap 2, so that the compression hemostasis component 3 can form a compression action on the wound site. After the strap 2 tightly binds the two ends of the compression plate 1 to the patient's body, one of the belt-like airbags 21 on the strap 2 can be inflated through the valve core 23 separately, so that the belt body of the strap 2 is further tightened, that is, the tightening and fixing can be achieved more firmly, and after a period of time, the other belt-like airbag can also be inflated through the valve core 23, and at the same time, the initially inflated belt-like airbag 21 is released through the valve core 23. The pressure plate 1 can adjust the part of the patient's body that is pressed and fixed to avoid long-term compression of the same part of the patient's body causing nerve and blood vessel damage in this part. When the pressing plate 1 presses down on the pressing hemostatic component 3, the pressing hemostatic component 3 can lift the movable inner shell 14 upward and move it a certain distance. At this time, the elastic inclined push rod 18 will be further bent due to the pressure on the pressing hemostatic component 3, that is, the elastic inclined push rod 18 can have an inward pushing force on the pressing hemostatic component 3, which can act on the patient's wound so that the pressing hemostatic component 3 can press the wound while also having an inward clamping and gathering effect on the wound, which can also have a certain hemostatic effect on the wound.
