Description

Technical Field

[0001] The present invention relates to the technical field of hemostatic compressors, and in particular to a hemostatic compressor for cardiology with adjustable pressure. Background Art

[0002] A hemostatic compressor for cardiology is a medical device used to control bleeding at the vascular puncture site, and is commonly used to compress and stop bleeding at the puncture point after cardiac catheterization procedures (such as coronary angiography, stent implantation, etc.), which can effectively control bleeding, improve the safety of the operation and the comfort of the patient.

[0003] Publication No. CN214761284U discloses a hemostatic compressor for cardiology, which includes a compressor main body. By setting a pressure sensor to sense the magnitude of the pressure exerted by the hemostatic compressor on the patient, the pressing force of the hemostatic compressor can be adjusted more intuitively, thus solving the problem that in the existing hemostatic compressor during use, medical staff cannot intuitively understand the force they exert on the patient, and if the force is too small, it cannot play a hemostatic role. Publication No. CN210644115U discloses a hemostatic compressor for cardiology. After observing through the display screen that the pressure of the tourniquet on the wound is appropriate, the rotation of the second bevel gear can be stopped, which can prevent mistakes that may occur during direct manual pressing. At the same time, when wearing this device, the wound can be aligned with the tourniquet, making the practicality of this device better.

[0004] Although the above two patents can both adjust the pressure of the hemostatic compressor, the pressing parts of both use hard force for pressing. This pressing method will cause discomfort to the patient, and when stopping bleeding, only the pressing method is used for hemostasis. This method has a poor hemostatic effect and requires long-term pressing to achieve a better hemostatic effect, and long-term pressing on the wound will also cause discomfort to the patient. Summary of the Invention

Multiple bent connecting rods are fixedly connected to the top of the circular plate, and one end of each bent connecting rod away from the circular plate is fixedly connected to a corresponding first pressing plate. A fourth elastic member is sleeved outside the second cylindrical rod. One end of the fourth elastic member abuts against the sealing plug, and the other end of the fourth elastic member abuts against the circular plate. It should be noted that the second elastic member, the first elastic member, the fourth elastic member, and the third elastic member can all use devices such as springs.

It should be noted that due to the arrangement of the limiting rods and the limiting grooves, the moving paths of the second cylindrical rod and the third conical plug in the up and down directions are restricted, so that the third conical plug can directly block the fourth conical groove after moving upward.

[0018] From the above technical solutions, the following beneficial effects of the present application can be seen: 1: When gas is filled into the first chamber, the gas will enter the first catheter through the air holes and drive the piston block to move downward. When the piston block moves downward, the water in the first catheter will be squeezed into the second chamber. The water in the second chamber will squeeze the rubber sheet, and the rubber sheet will expand and press the gauze on the wound, thereby playing a role in pressing and stopping bleeding. Moreover, the pressure caused by the water squeezing the rubber sheet to make the rubber sheet expand is gentle, which is more comfortable than the existing pressing plate.

[0019] 2: When the third conical plug no longer blocks the fourth conical groove, the heat-absorbing powder in the hollow column will fall from the round hole and the fourth conical groove into the water in the second chamber. The heat-absorbing powder can be one of ammonium nitrate, ammonium chloride, sodium nitrate, and sodium nitrite. These powders are extremely soluble in water and absorb heat when dissolved in water, thereby cooling the water. That is, the cooled water can also play a role in cold compressing the wound. During cold compressing, the local temperature of the wound is reduced, causing blood vessels to contract, thereby reducing blood flow and achieving the effect of stopping bleeding. That is, the hemostatic effect is faster, the time for pressing and stopping bleeding is shortened, and the discomfort caused by pressing is reduced.

[0020] 3: When inflating the first chamber, the downward movement of the piston block can not only squeeze the water in the first conduit into the second chamber to drive the rubber sheet to expand, so that the rubber sheet presses on the wound, but also drive the first piston rod and the first pressing plate to move downward when the piston block moves downward. When the first pressing plate moves downward, it can drive the second cylindrical rod and the third conical plug to move downward through the bent connecting rod, that is, the heat-absorbing powder in the hollow column will also fall into the water in the first chamber. That is, inflation can not only cause the rubber sheet to expand, but also inject the heat-absorbing powder into the water to cool the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Refer toFigures 1 - 10 : As an embodiment of the present invention, a pressure-adjustable hemostatic compressor for cardiology is provided, which includes a main body unit 100 and a hemostatic unit 200. The main body unit 100 includes a cylinder 101. A first strap 102 and a second strap 103 are fixed on the outer side of the cylinder 101. A hook surface 104 is arranged on one side of the first strap 102, and a plush surface 105 is arranged on one side of the second strap 103. The hook surface 104 and the plush surface 105 are adhered to each other. A pressure gauge 106 is installed on the cylinder 101. The hemostatic unit 200 includes a partition 201, and the partition 201 is fixed inside the cylinder 101. A rubber sheet 204 is fixed at the bottom of the cylinder 101. The partition 201 divides the space between the cylinder 101 and the rubber sheet 204 into a first chamber 202 and a second chamber 203. A plurality of first conduits 205 are fixed in the partition 201, and the first conduits 205 communicate with the second chamber 203. A piston block 206 is hermetically and slidably connected in the first conduit 205. The first conduits 205 and the second chamber 203 are filled with water. An extrusion assembly for extruding the water in the first conduit 205 into the second chamber 203 is arranged in the first chamber 202. After the water in the first conduit 205 is extruded into the second chamber 203, the water in the second chamber 203 increases and extrudes the rubber sheet 204, and the rubber sheet 204 expands and presses the gauze at the wound after being affected.

[0028] Specifically, the extrusion assembly includes a circular plate 207 fixed on the first conduit 205. A first piston rod 208 is fixed on the piston block 206. The first piston rod 208 penetrates through the circular plate 207 and slides inside the circular plate 207. A plurality of air holes 209 are formed in the circular plate 207. A first pressing plate 210 is fixed at the top of the first piston rod 208. A first elastic member 211 is sleeved outside the first piston rod 208. One end of the first elastic member 211 abuts against the circular plate 207, and the other end of the first elastic member 211 abuts against the first pressing plate 210. A water pipe 222 is fixed on the cylinder 101, and the water pipe 222 communicates with the second chamber 203. One end of the water pipe 222 is threadedly connected with a threaded cap 223. A hollow column 224 is fixed in the middle of the partition 201. A second conduit 225 is fixed and communicated with the hollow column 224. The second conduit 225 penetrates through the cylinder 101 and is fixed to the cylinder 101 and extends outside the cylinder 101. The axes of the hollow column 224, the partition 201, the second conduit 225, and the cylinder 101 coincide.

[0029] Among them, a rubber column 226 is fixed to the inner wall of the bottom of the second conduit 225. A second conical groove 227 is formed at the top of the rubber column 226, a third conical groove 228 is formed at the bottom of the rubber column 226, and a circular groove 229 is formed in the middle of the rubber column 226. The top and bottom of the circular groove 229 are respectively communicated with the second conical groove 227 and the third conical groove 228. Limiting rings 232 are arranged at the top and middle of the second conduit 225. A plurality of support rods 233 are fixed to the outer side of the limiting ring 232 at equal intervals along its radial direction, and one end of the support rod 233 away from the limiting ring 232 is fixed to the inner wall of the second conduit 225. A first cylindrical rod 231 is slidably connected in the limiting ring 232. A second conical plug 230 is fixed to the bottom of the first cylindrical rod 231. The second conical plug 230 can block the third conical groove 228. It should be noted that due to the arrangement of the limiting ring 232, the path of the up and down movement of the first cylindrical rod 231 is restricted, so that the second conical plug 230 can accurately block the third conical groove 228 after moving up. A third pressing plate 234 is fixed to the top of the first cylindrical rod 231. A third elastic member 235 is sleeved on the outer side of the first cylindrical rod 231. One end of the third elastic member 235 abuts against the limiting ring 232, and the other end of the third elastic member 235 abuts against the third pressing plate 234. It should be noted that the third elastic member 235 can use devices such as springs, and in the normal state of the third elastic member 235, the second conical plug 230 blocks the third conical groove 228. The vertical cross-sectional diameter of the second conical groove 227 gradually decreases from top to bottom, and the vertical cross-sectional diameters of the third conical groove 228 and the second conical plug 230 gradually increase from top to bottom. The diameter of the circular groove 229 is larger than the diameter of the first cylindrical rod 231.

[0030] During use, first open the threaded cap 223, inject water from the water pipe 222 into the second chamber 203 and the first conduit 205, then pour the heat-absorbing powder into the second conduit 225, and then press the third pressing plate 234 to drive the first cylindrical rod 231 to move down. When the first cylindrical rod 231 moves down, it drives the second conical plug 230 to move down. When the second conical plug 230 no longer blocks the third conical groove 228, the heat-absorbing powder falls from the circular groove 229 and the third conical groove 228 into the hollow column 224. Then release the third pressing plate 234. At this time, under the resilience of the third elastic member 235, the third pressing plate 234 and the first cylindrical rod 231 are driven to move up, so that the second conical plug 230 blocks the third conical groove 228. Then cover the wound of the patient with a gauze, and then place the cylinder body 101 on the gauze. After that, wrap the first strap 102 and the second strap 103 around the patient's body, and then bond the hook surface 104 and the pile surface 105, so that the cylinder body 101 is fixed on the gauze.

[0031] In addition, an externally threaded pipe 212 is fixed on the cylinder body 101, and the externally threaded pipe 212 communicates with the first chamber 202. A baffle 213 is fixed inside the externally threaded pipe 212. A first tapered groove 216 is formed inside the baffle 213. A plurality of through grooves 217 are formed inside the baffle 213. A slide rod 214 is hermetically slidable inside the through groove 217. One end of the slide rod 214 is fixed with a connecting plate 221. The ends of the plurality of connecting plates 221 away from the slide rod 214 are commonly fixed with a second piston rod 220. One end of the second piston rod 220 is fixed with a first tapered plug 219. The first tapered plug 219 can block the first tapered groove 216. The vertical cross-sectional diameters of the first tapered groove 216 and the first tapered plug 219 gradually increase from the externally threaded pipe 212 towards the cylinder body 101. The end of the slide rod 214 away from the connecting plate 221 is fixed with a second pressing plate 218. A second elastic member 215 is sleeved outside the slide rod 214. One end of the second elastic member 215 abuts against the second pressing plate 218, and the other end of the second elastic member 215 abuts against the baffle 213.

[0032] During use, the air delivery pipe of an external inflation device is threadedly connected to the externally threaded pipe 212. When the external inflation device is opened, the gas will impact the first tapered plug 219 and drive the first tapered plug 219 to move. When the first tapered plug 219 no longer blocks the first tapered groove 216, the gas enters the first chamber 202 from the first tapered groove 216. After the gas enters the first chamber 202, the gas will enter the first conduit 205 from the air hole 209 and drive the piston block 206 to move downward. When the piston block 206 moves downward, the water in the first conduit 205 is squeezed into the second chamber 203. The water in the second chamber 203 will squeeze the rubber sheet 204, and the rubber sheet 204 will expand and press the gauze on the wound, thereby playing a role in pressing to stop bleeding. Moreover, the pressure caused by the water squeezing the rubber sheet 204 to make the rubber sheet 204 expand is gentle, which is more comfortable than the existing pressing plate. It should be noted that by observing the pressure value of the pressure gauge 106, the first chamber 202 can be reasonably inflated to adjust the pressure of the rubber sheet 204. When the inflation is over, at this time, the second elastic member 215 drives the slide rod 214 to move under the resilience force. When the slide rod 214 moves, it drives the connecting plate 221 and the second piston rod 220 to move. When the second piston rod 220 moves, it drives the first tapered plug 219 to move, so that the first tapered plug 219 blocks the first tapered groove 216 again, thereby preventing the gas in the first chamber 202 from overflowing.

[0033] In addition, a plurality of sealing plugs 240 are fixed to the top of the hollow column 224. A second cylindrical rod 239 is sealed and slidably arranged inside the sealing plug 240. A plurality of round holes 236 and fourth tapered grooves 237 are formed in the bottom of the hollow column 224, and the round holes 236 communicate with the corresponding fourth tapered grooves 237. A third tapered plug 238 is fixed to the bottom of the second cylindrical rod 239. The third tapered plug 238 can block the fourth tapered groove 237. The vertical cross-sectional diameters of the fourth tapered groove 237 and the third tapered plug 238 gradually decrease from top to bottom. A plurality of second cylindrical rods 239 are jointly fixed to the top of an annular plate 241. A plurality of bent connecting rods 245 are fixed to the top of the annular plate 241, and one end of the bent connecting rod 245 far away from the annular plate 241 is fixed to the corresponding first pressing plate 210. A fourth elastic member 242 is sleeved outside the second cylindrical rod 239. One end of the fourth elastic member 242 abuts against the sealing plug 240, and the other end of the fourth elastic member 242 abuts against the annular plate 241. A plurality of limiting grooves 244 are formed in the outer side of the second conduit 225. A plurality of limiting rods 243 are fixed to the inner wall of the annular plate 241 at equal intervals along its radial direction. The plurality of limiting rods 243 are respectively slidably fitted in the corresponding limiting grooves 244. It should be noted that due to the arrangement of the limiting rods 243 and the limiting grooves 244, the moving paths of the second cylindrical rod 239 and the third tapered plug 238 in the up and down directions are restricted, so that the third tapered plug 238 can directly block the fourth tapered groove 237 after moving upward.

[0034] It should be noted that the second elastic member 215, the first elastic member 211, and the fourth elastic member 242 can all use devices such as springs. In the normal state of the first elastic member 211 and the fourth elastic member 242, the third tapered plug 238 blocks the fourth tapered groove 237. In the normal state of the second elastic member 215, the first tapered plug 219 blocks the first tapered groove 216.

[0035] During use, when the first chamber 202 is inflated, the gas enters the first conduit 205 through the air hole 209, driving the piston block 206 to move downward. When the piston block 206 moves downward, it drives the first piston rod 208 to move downward. When the first piston rod 208 moves downward, it drives the first pressing plate 210 to move downward. When the first pressing plate 210 moves downward, it drives the bent connecting rod 245 to move downward. When the bent connecting rod 245 moves downward, it drives the annular plate 241 to move downward. When the annular plate 241 moves downward, it drives the second cylindrical rod 239 and the third tapered plug 238 to move downward, so that the third tapered plug 238 no longer blocks the fourth tapered groove 237. At this time, the heat-absorbing powder in the hollow column 224 will fall from the round hole 236 and the fourth tapered groove 237 into the water in the second chamber 203. It should be noted that the heat-absorbing powder can be one of ammonium nitrate, ammonium chloride, sodium nitrate, and sodium nitrite. These powders are extremely soluble in water and absorb heat when dissolved in water, thereby cooling the water. That is, the cooled water can still play a role in cold compress on the wound. During cold compress, the local temperature of the wound is reduced, causing blood vessels to constrict, thereby reducing blood flow and achieving the effect of hemostasis. That is, the hemostasis effect is faster, the time for pressing to stop bleeding is shortened, and the discomfort caused by pressing is reduced.
