Detailed ways

The specific embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

1 to 2, the hemostatic device of the present invention, which is convenient for adjusting the extrusion pressure, is schematically shown, including a belt body 1 in a ring structure. Of course, the belt body 1 can be a fixed and closed ring structure, or It can be a ring structure closed by existing snaps. The belt body 1 is provided with a control mechanism 2 and a plurality of bladders 3 disposed on the inner side of the belt 1 . The bladders 3 are hollow structures and can be filled with gas to inflate the bladders 3 . The control mechanism 2 includes a gas distribution chamber 21, a gas nozzle 22 and a pressure relief valve 23 connected to the gas distribution chamber 21. The gas nozzle 22 is used to connect the existing high-pressure gas source such as a gas storage tank, and the pressure relief valve 23 is provided with a The adjustment knob 231 for adjusting the pressure relief pressure and the scale for displaying the stroke of the adjustment knob 231, the air distribution chamber 21 is communicated with the bag body 3 through the one-way valve 25, and the air distribution chamber 21 is filled with high-pressure gas from the air nozzle 22, The high pressure gas enters the balloon 3 through the one-way valve 25 to inflate the balloon 3 and squeeze the patient's limb. Since the restraint tightness of the device can be adjusted by adjusting the pressure relief pressure, first adjust the pressure relief pressure to the corresponding pressure relief pressure according to the thickness of the patient's limb and the bleeding situation, and then directly inflate the gas nozzle 22 through the above air source, and force the balloon body 3 to expand to the corresponding size (the size of the bladder 3 depends on the size of the inflated air pressure). Because the pressure relief valve 23 limits the air pressure of the gas charged into the bladder 3, after the gas nozzle 22 is connected to the high-pressure gas source, the high-pressure gas source can be disconnected when the pressure relief valve 23 is observed to release pressure and exhaust. The balloon body 3 will be inflated to an appropriate size, and the operation is extremely simple. And the inflatable balloon body 3 improves the restraint comfort of the patient.

The device also includes a decompression plate 4, which is detachably connected to the inner side of the belt body 1, and the decompression plate 4 is used to expand the contact area of the device with the skin and reduce the pressure of the skin in contact with the decompression plate 4. , to reduce the discomfort caused by the device to the patient. It should be noted that the multiple balloons 3 are used to compress the arteries near the bleeding site, while the decompression plate 4 is to relieve the pressure on the other side of the limb and avoid The entire limb is subjected to greater squeezing force. Further, the pressure relief plate 4 is provided with a connection block perpendicular to it, and the connection block is provided with a limit block perpendicular to it, the limit block, the connection block and the pressure relief plate 4 form a limit groove, and the belt body 1 can be inserted into the limit slot.

Specifically, the device further includes a plurality of air conduits arranged on the belt body 1 , the two ends of the air conduits are respectively connected to the air distribution chamber 21 and the bag body 3 , and the one-way valve 25 is provided on the air conduit and communicated with the air distribution chamber 21 . On one end of the device, the band body 1 acts as the main force-bearing element to ensure that the balloon body 3 expands toward the center of the annular band body 1 during the hemostasis process of the device.

The check valve 25 is also provided with a toggle lever connected to its valve core, and a plurality of toggle levers are connected to the transmission rod. When the transmission lever is pulled, the toggle lever can be toggled at the same time, thereby driving the valve core of the one-way valve 25 to move. , so that the valve core of the one-way valve 25 is opened and the gas in the bladder 3 is discharged to the gas distribution chamber 21 . The control mechanism 2 also includes an exhaust valve 24 connected to the air distribution chamber 21. The valve core of the exhaust valve 24 is also connected to the transmission rod. Therefore, when the transmission rod is pulled, the exhaust valve 24 makes the air distribution chamber 21 communicate with the transmission rod. The outside atmosphere is used to discharge the gas in the capsule body 3 .

To sum up, the hemostatic device of the present invention, which is convenient for adjusting the extrusion pressure, has a belt body 1 in an annular structure, and a plurality of capsule bodies 3 are arranged on the inner side of the belt body 1, and the capsule bodies 3 are connected to the The air distribution chamber 21 is provided with a pressure relief valve 23 on the air distribution chamber 21. The medical staff can rotate the adjustment knob 231 according to the scale to adjust the relief pressure of the relief valve 23. By adjusting the relief pressure, the device can be adjusted. The tightness of the restraint is first adjusted to the corresponding pressure relief pressure according to the thickness of the patient's limb and the bleeding situation, and the gas nozzle 22 is inflated by a high-pressure air source such as an air tank, and the balloon 3 is inflated and compresses the patient's limb to achieve rapid hemostasis and the inflatable bag body 3 is softer, which improves the comfort of restraint.
