[0034] In order to solve this technical problem, the present invention provides a femoral artery hemostat with a deflation timing function, which is used for timed deflation when performing hemostasis on the femoral artery.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] A femoral artery hemostat with a deflation timing function comprises a support plate 101, a deflation barrel 102 is fixedly connected to the upper surface of the support plate 101, a spring 103 is fixedly connected to the upper surface of the support plate 101, a baffle 104 is fixedly connected to the upper end of the spring 103, a limited position air cushion 105 is fixedly connected to the upper surface of the baffle 104, an exhaust hole 106 is provided on the outer surface of the deflation barrel 102, a movable plate 107 is rotatably connected to the upper surface of the inner wall of the exhaust hole 106, a deflation plate 108 is hingedly connected to the movable plate 107 near the inner wall of the deflation barrel 102, and a through hole 109 is provided on the outer surface of the deflation plate 108.

[0039] When deflation is performed, the bandage 401 is fixed to the stoma of the patient, followed by the first flow valve 301 and the second flow valve 302. At this time, the airbag 501 is squeezed and pressed, and the generated gas enters the movable air cushion 202 along the air supply pipe 201 to stop bleeding. Then the second flow valve 302 is closed to inflate the limiting air cushion 105 to squeeze the baffle 104, so that the inside of the deflation barrel 102 fits the limiting air cushion 105. After hemostasis is completed, deflation is performed. During deflation, the first flow valve 301 is closed, and the gas inside the movable air cushion 202 is discharged into the deflation barrel 102 along the deflation hole 601 and drives the baffle 104 to move upward. During the movement of the baffle 104, its upper surface drives the deflation plate 108 and the movable plate 107 to rotate, so that the movable plate 107 is aligned with the exhaust hole 106 in the vertical direction. At this time, the gas inside the deflation barrel 102 is discharged for deflation, and then the baffle 104 continues to slide and drives the upper deflation plate 108 to rotate to achieve secondary deflation. During the sliding process, the diameter of the deflation hole 601 remains unchanged, thereby making the deflation speed unchanged, so that the baffle 104 slides at a uniform speed to achieve timed exhaust.

[0040] The upper and lower surfaces of the limiting air cushion 105 are connected to the air supply pipe 201. The lower end of the air supply pipe 201 passes through the support plate 101 and is connected to the movable air cushion 202. The lower surface of the movable air cushion 202 is fixedly connected to a silicone gasket 203, and the lower surface of the silicone gasket 203 is pasted with an application 204.

[0041] The air supply pipe 201 connected to the upper and lower surfaces of the limiting air cushion 105 is used to transport the generated gas to the inside of the limiting air cushion 105 for hemostasis. The lower end of the air supply pipe 201 passes through the support plate 101 and is connected to the movable air cushion 202, which is used to control the pressure on the femoral artery to achieve hemostasis. The silicone gasket 203 fixedly connected to the lower surface of the movable air cushion 202 is used to align with the femoral artery for rapid hemostasis. The patch 204 pasted on the lower surface of the Gujiao gasket can be adhered to the skin to prevent displacement during deflation.

[0042] A first flow valve 301 is installed on the outer surface of the gas pipe 201 below the limiting air cushion 105 , and a second flow valve 302 is installed on the outer surface of the gas pipe 201 above the limiting air cushion 105 .

[0043] The first flow valve 301 installed on the outer surface of the air pipe 201 below the limiting air cushion 105 and the second flow valve 302 installed on the outer surface of the air pipe 201 above the limiting air cushion 105 are used to control the connection state of the air pipe 201 deflation cylinder and the limiting air cushion 105.

[0044] A strap 401 is sleeved on the side of the support plate 101 , and two ends of the strap 401 are respectively fixedly connected with Velcro 402 , and the Velcro 402 is adhered to the lower surface of the strap 401 .

[0045] The strap 401 sleeved on the side of the support plate 101 is used to fix the hemostatic device to the femoral artery, and the Velcro 402 fixedly connected at both ends of the strap 401 fixes the strap 401 through adhesion.

[0046] The upper end of the air delivery pipe 201 passes through the air release barrel 102 and is connected to the pressing airbag 501. The movable air cushion 202 and the silicone gasket 203 are located between the straps 401, and the straps 401 wrap around them.

[0047] The upper end of the air supply tube 201 passes through the deflation barrel 102 and is connected to the pressing airbag 501 so that the airbag 501 can be pressed to generate gas and transported to the active air cushion 202 through the air supply tube 201 for hemostasis. The active air cushion 202 and the silicone gasket 203 are arranged between the strap 401 for stoma to squeeze and stop bleeding.

[0048] An air release hole 601 is provided on the upper surface of the support plate 101 . The air release hole 601 is connected to the movable air cushion 202 and has a diameter smaller than that of the air delivery pipe 201 .

[0049] The vent hole 601 arranged on the upper surface of the support plate 101 is used to discharge the air in the limiting air cushion 105 to achieve deflation. In addition, the vent hole 601 is connected to the limiting air cushion 105 and its diameter is set to be smaller than the air supply pipe 201 to prevent the pressure from being lost due to excessive deflation and inability to stop bleeding.

[0050] There are two exhaust holes 106 distributed on the side of the air release barrel 102 , and the two exhaust holes 106 form a height difference, and the inner surface of each exhaust hole 106 is rotatably connected to a movable plate 107 .

[0051] There are two exhaust holes 106 distributed on the side of the air release barrel 102 to form a height difference to achieve timed deflation. When the baffle 104 moves to different positions, the exhaust holes 106 will deflate, and when moving, they will rise at a uniform speed according to the gas changes inside the air release barrel 102.

[0052] The baffle plate 104 abuts against the degassing plate 108 , and the outer surface thereof is slidably connected to the degassing barrel 102 .

[0053] The baffle plate 104 abuts against the degassing plate 108 and the degassing plate 108 can be rotated by sliding the baffle plate 104 to discharge the gas.

[0054] The use process of the femoral artery hemostat with deflation timing function provided by the present invention is as follows:

[0055] When deflation is performed, the bandage 401 is fixed to the stoma of the patient, followed by the first flow valve 301 and the second flow valve 302. At this time, the airbag 501 is squeezed and pressed, and the generated gas enters the movable air cushion 202 along the air supply pipe 201 to stop bleeding. Then the second flow valve 302 is closed to inflate the limiting air cushion 105 to squeeze the baffle 104, so that the inside of the deflation barrel 102 fits the limiting air cushion 105. After hemostasis is completed, deflation is performed. During deflation, the first flow valve 301 is closed, and the gas inside the movable air cushion 202 is discharged into the deflation barrel 102 along the deflation hole 601 and drives the baffle 104 to move upward. During the movement of the baffle 104, its upper surface drives the deflation plate 108 and the movable plate 107 to rotate, so that the movable plate 107 is aligned with the exhaust hole 106 in the vertical direction. At this time, the gas inside the deflation barrel 102 is discharged for deflation, and then the baffle 104 continues to slide and drives the upper deflation plate 108 to rotate to achieve secondary deflation. During the sliding process, the diameter of the deflation hole 601 remains unchanged, thereby making the deflation speed unchanged, so that the baffle 104 slides at a uniform speed to achieve timed exhaust.
