Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an intelligent radial artery compression hemostat. Background Art

[0002] After blood is drawn or punctured, the radial artery needs to be compressed for a long time to stop bleeding. The commonly used method for compressing and stopping bleeding is to use a compression hemostat. The traditional compression hemostat is to manually turn the knob to drive the screw to drive the compression pad to move, thereby achieving the purpose of compression and stopping bleeding.

[0003] However, the above-mentioned compression hemostat has the following disadvantages:

[0004] Since both compression and decompression are performed by rotating the same knob, and there is no restriction on the angle of a single rotation of the knob, during the decompression process, it is very likely that the medical staff rotates the knob too large, causing the screw to rise a large distance, thereby causing the pressure at the radial artery puncture point to decrease too quickly, causing the radial artery puncture point to bleed again, and requiring secondary compression to stop the bleeding. Summary of the invention

[0051] like Figure 1-15As shown, the present invention provides a radial artery intelligent compression hemostat, including a base plate 100, a fixing belt 110, a compression block 120, a compression pad 130 and an adjusting screw 140. The first end and the second end of the base plate 100 are respectively provided with a first through hole 101 and a second through hole 102. The first end of the fixing belt 110 is fixedly connected to the base plate 100 through the first through hole 101, and the second end can pass through the second through hole 102 and then be adhesively connected to the side of the fixing belt 110. The compression block 120 is arranged on the inner side of the base plate 100 and is slidably connected to the base plate 100. The compression pad 130 is arranged on a side of the compression block 120 away from the base plate 100 and is fixedly connected to the compression block 120. The adjusting screw 140 is rotatably connected to the base plate 100, and its first end is fixedly connected to the compression block 120, and the second end extends to the outside of the base plate 100. These are all prior arts, and will not be described in detail here.

[0053] The driven gear 150 is installed on the outside of the base plate 100 and is rotatably connected with the base plate 100. The driven gear 150 is coaxially sleeved on the adjusting screw 140 and is threadedly connected with the adjusting screw 140, and the spiral direction of the thread of the adjusting screw 140 is positive. When in use, when the driven gear 150 is rotated in the reverse direction, the adjusting screw 140 moves toward the inside of the base plate 100 under the action of the threaded connection between the driven gear 150 and the adjusting screw 140, thereby moving with the compression block 120 and the compression pad 130, thereby achieving the purpose of pressurizing the radial artery puncture point; when the driven gear 150 is rotated in the forward direction, the adjusting screw 140 moves toward the outside of the base plate 100 under the action of the threaded connection between the driven gear 150 and the adjusting screw 140, thereby moving with the compression block 120 and the compression pad 130, thereby achieving the purpose of decompression. Here, there is no restriction on the forward and reverse directions. When the spiral direction of the thread of the adjusting screw 140 is clockwise, the clockwise direction is the forward direction in the present invention, and the counterclockwise direction is the reverse direction in the present invention. Conversely, when the spiral direction of the thread of the adjusting screw 140 is counterclockwise, the clockwise direction is the reverse direction in the present invention, and the counterclockwise direction is the forward direction in the present invention.

[0054] The first sliding seat 160 is installed on one side of the driven gear 150 and is slidably connected to the base plate 100. It can make reciprocating linear motion between the first working position A and the second working position A along the radial direction of the driven gear 150. The first driving gear 161 is rotatably provided on the side away from the base plate 100. When the first sliding seat 160 is in the first working position A, the first driving gear 161 is meshed with the driven gear 150. When the first sliding seat 160 is in the second working position A, the first driving gear 161 and the driven gear 150 are separated from each other. Specifically, the side of the first sliding seat 160 away from the base plate 110 is fixedly connected with the second housing 162, and the first driving gear 161 is rotatably installed in the second housing 162. When in use, the first sliding seat 160 can be placed in the first working position A or the second working position A, so as to achieve the purpose of meshing or separating the first driving gear 161 and the driven gear 150.

[0055] The second sliding seat 170 is installed on the other side of the driven gear 150 and is slidably connected to the base plate 100. It can make reciprocating linear motion between the first working position B and the second working position B along the radial direction of the driven gear 150. The second driving gear 171 is rotatably provided on the side away from the base plate 100. When the second sliding seat 170 is in the first working position B, the second driving gear 171 is meshed with the driven gear 150. When the second sliding seat 170 is in the second working position B, the second driving gear 171 is separated from the driven gear 150. Specifically, the side of the second sliding seat 170 away from the base plate 110 is fixedly connected with the third housing 172. The second driving gear 171 is rotatably installed in the third housing 172. When in use, the second sliding seat 170 can be placed in the first working position B or the second working position B, so as to achieve the purpose of meshing or separating the second driving gear 171 from the driven gear 150.

[0056] Specifically, a first shell 103 is disposed on the outer side of the base plate 110 , and the first sliding seat 160 and the second sliding seat 170 are both slidably disposed in the first shell 103 .

[0057] The first knob 180 is rotatably mounted on the first sliding seat 160, and is coaxially arranged with the first driving gear 161 and is in transmission connection with the first driving gear 161. Specifically, the first knob 180 is mounted on the first sliding seat 160 through the second housing 162. When in use, the first sliding seat 160 can be placed in the first working position A so that the first driving gear 161 is meshed with the driven gear 150, so as to achieve the purpose of driving the first driving gear 161 to rotate through the first knob 180, and then achieve the purpose of driving the compression block 120 and the compression pad 130 to move through the adjusting screw 140 to pressurize or decompress the puncture point of the radial artery. When it is not necessary to rotate the driven gear 150 through the first driving gear 161, the first sliding seat 160 can be placed in the second working position A, so as to achieve the purpose of locking the rotation of the adjusting screw 140.

[0058] The second knob 190 is mounted on the second sliding seat 170, and is coaxially arranged with the second driving gear 171 and is in transmission connection with the second driving gear 171, and can only drive the second driving gear 171 to rotate in the reverse direction. Specifically, the second knob 190 is rotatably mounted on the second sliding seat 170 through the third housing 172. When in use, the second sliding seat 170 can be placed in the first working position B, so that the second driving gear 171 is meshed with the driven gear 150, thereby achieving the purpose of driving the second driving gear 171 to rotate through the second knob 190, and thereby achieving the purpose of driving the compression block 120 and the compression pad 130 to move through the adjusting screw 140 to decompress the puncture point of the radial artery. When the driven gear 150 does not need to be rotated through the second driving gear 171, the second sliding seat 170 can be placed in the second working position B, thereby achieving the purpose of locking the rotation of the adjusting screw 140.

[0059] The power input end of the transmission assembly 200 is transmission-connected with the second knob 190, and the power output end is transmission-connected with the adjusting screw 140, which is used to control the second knob 190 to drive the adjusting screw 140 to rotate in the reverse direction at a preset angle each time. When in use, when decompression is required, the second sliding seat 170 is placed at the first working position B, so that the second driving gear 171 is meshed with the driven gear 150, and the first sliding seat 160 is placed at the second working position A, so that the first driving gear 161 is separated from the driven gear 150, so that the medical staff can only drive the adjusting screw 140 to move for decompression through the second knob 190. In this process, under the action of the transmission assembly 200, the second knob 190 can only drive the adjusting screw 140 to rotate in the reverse direction at a preset angle each time, thereby achieving the purpose of controlling the single stroke of the adjusting screw 140, thereby achieving the purpose of avoiding the radial artery puncture point from bleeding again due to the rapid blood pressure reduction caused by the excessive movement of the adjusting screw 140, and further achieving the purpose of avoiding secondary compression.

[0060] The locking assembly includes two locking units 300, one of which is used to maintain the first sliding seat 160 in the first working position A and the second working position A. Specifically, when the first sliding seat 160 is in the first working position A, under the action of the locking unit 300, the first sliding seat 160 is maintained in the first working position A, and when the first sliding seat 160 is in the second working position A, under the action of the locking unit 300, the first sliding seat 160 is maintained in the second working position A; the other locking unit 300 is used to maintain the second sliding seat 170 in the first working position B and the second working position B. Specifically, when the second sliding seat 170 is in the first working position B, under the action of the locking unit 300, the second sliding seat 170 is maintained in the first working position B, and when the second sliding seat 170 is in the second working position B, under the action of the locking unit 300, the second sliding seat 170 is maintained in the second working position B.

[0061] During use, when it is necessary to compress the radial artery puncture point to stop bleeding, the first sliding seat 160 is placed in the first working position A, and the second sliding seat 170 is placed in the second working position B, and then the first knob 180 is rotated forward, the first knob 180 drives the first driving gear 161 to rotate forward, and the first driving gear 161 drives the driven gear 150 to rotate in the opposite direction, thereby achieving the purpose of driving the compression block 120 and the compression pad 130 to move toward the inner side of the base plate 100 through the adjusting screw 140, thereby achieving the purpose of pressurized hemostasis.

[0062] When hemostasis is completed and decompression is required, the first sliding seat 160 is placed in the second working position A, and the second sliding seat 170 is placed in the first working position B. Then, by rotating the second knob 190 in the opposite direction, the first knob 180 drives the second driving gear 171 to rotate through the transmission assembly 200. Under the action of the transmission assembly 200, the first knob 180 can only drive the second driving gear 171 to rotate at a preset angle each time, thereby achieving the purpose of controlling a single stroke of the adjusting screw 140, thereby achieving the purpose of avoiding bleeding again at the radial artery puncture point due to a rapid reduction in blood pressure due to the adjusting screw 140 moving too fast, thereby achieving the purpose of avoiding secondary compression.

[0063] The radial artery intelligent compression hemostat provided by the present invention achieves the purpose of controlling the single stroke of the adjusting screw 140 during decompression by arranging the driven gear 150, the first sliding seat 160, the second sliding seat 170, the first driving gear 161, the second driving gear 171, the first knob 180, the second knob 190, the transmission assembly 200 and the locking assembly, thereby achieving the purpose of avoiding bleeding again at the radial artery puncture point due to excessively rapid blood pressure reduction during the decompression process, thereby achieving the purpose of avoiding secondary compression.

[0064] In one embodiment, the first knob 180 is transmission-connected with the first driving gear 161 through the ratchet structure 500 so that the first knob 180 can only drive the first driving gear 161 to rotate in the forward direction. When in use, since the first knob 180 is transmission-connected with the first driving gear 161 through the ratchet structure 500, the first knob 180 can only drive the first driving gear 161 to rotate in the forward direction but cannot drive the first driving gear 161 to rotate in the reverse direction, that is, the first knob 180 can only achieve the purpose of pressurization but cannot decompress, thereby achieving the purpose of avoiding decompression through the first knob 180 due to operational errors of medical staff.

[0065] In one embodiment, the transmission assembly 200 includes a transmission plate 210 , a first latch 220 , a second latch 230 , a first spring 240 , a second spring 250 , an arc-shaped slot 260 and a limiting shaft 270 .

[0066] The transmission disc 210 is coaxially arranged with the second driving gear 171 and fixedly connected to the second driving gear 171, and its circumferential wall is provided with a plurality of evenly distributed and penetrating grooves 211, and the grooves 211 have blocking walls 201 and guide walls 202, the blocking walls 201 extend along the radial direction of the transmission disc 210, and the guide walls 202 gradually approach the axis of the transmission disc 210 from the circumferential surface of the transmission disc 210 in the reverse direction. In this way, when in use, the transmission disc 210 can only be driven to rotate in the reverse direction through the grooves 211.

[0067] The first latch 220 is slidably connected to the second knob 190. Specifically, the first latch 220 is slidably inserted in the first sleeve 191, and the first sleeve 191 is fixedly connected to the second knob 191. The first latch 220 can reciprocate between the first working position C and the second working position C along the radial direction of the transmission plate 210. When the first latch 220 is in the first working position C, the first end of the first latch 220 can be inserted into the groove 211 and abut against the blocking wall 201. When the first latch 220 is in the second working position C, the first end of the first latch 220 is located outside the groove 211. When in use, when the first latch 220 is in the first working position C, the first end of the first latch 220 is in the groove 211, and when the second knob 190 is rotated in the reverse direction, under the action of the blocking wall 201, the second knob 190 can drive the transmission disk 210 to rotate in the reverse direction, thereby driving the second driving gear 171 to rotate in the reverse direction through the transmission disk 210, and then driving the driven gear 150 to rotate in the forward direction; and when the second knob 190 is rotated in the forward direction, under the action of the guide wall 202, the second end of the first latch 220 will move along the guide wall 202 in the direction away from the axis of the transmission disk 210 and finally move to the outside of the groove 211, therefore, the transmission disk 210 cannot be driven to rotate in the forward direction, thereby the second driving gear 171 cannot be driven to rotate in the forward direction, and then the driven gear 150 cannot be driven to rotate in the reverse direction.

[0068] The second latch 230 is staggered with the first latch 220. The second latch 230 is slidably connected with the second sliding seat 170. Specifically, the second latch 230 is slidably inserted in the second sleeve 173, and the second sleeve 173 is fixedly connected with the second sliding seat 170. The second latch 230 can reciprocate linearly between the first working position D and the second working position D along the radial direction of the transmission plate 210, wherein when the second latch 230 is in the first working position D, the first end of the second latch 230 can be inserted into the groove 211 and abut against the blocking wall 201, and when the second latch 230 is in the second working position D, the first end of the second latch 230 is located outside the groove 211. When in use, when the second latch 230 is in the first working position, the first end of the second latch 230 is inserted into the groove 211, and under the action of the blocking wall 201, the second latch 230 prevents the transmission disk 210 from rotating in the forward direction, so that when the second knob 190 rotates in the reverse direction, the transmission disk 210 will not be driven to rotate in the forward direction due to the action of the friction force, and when the second knob 190 rotates in the reverse direction, under the action of the blocking wall 201 of the groove 211 corresponding to the first latch 220, the first latch 220 can drive the transmission disk 210 to rotate in the forward direction, and under the action of the guide wall 202 of the groove 211 corresponding to the second latch 230, the second latch 230 moves in a direction away from the axial center line of the transmission disk 210, thereby not preventing the transmission disk 210 from rotating in the reverse direction.

[0069] The first spring 240 is disposed at the second end of the first latch 220. Specifically, the first spring 240 is installed in the first sleeve 191, and its two ends are respectively in contact with the first latch 220 and the first sleeve 191, and in a natural state, the first spring 240 has a tendency to move the first latch 220 toward the axis of the transmission disk 210. The second spring 250 is disposed at the second end of the second latch 230. The second spring 250 is installed in the second sleeve 173, and its two ends are respectively in contact with the second latch 230 and the second sleeve 173, and in a natural state, the second spring 250 has a tendency to move the second latch 230 toward the axis of the transmission disk 210.

[0070] The arc groove 260 is provided on the second sliding seat 170 and is coaxially arranged with the second knob 190. Specifically, the arc groove is provided on the second housing 172. The limiting shaft 270 is inserted in the arc groove 260 and is fixedly connected with the second knob 190.

[0071] When the limiting shaft 270 is located at the first end and the second end of the arc groove 260 , the first ends of the first latch 220 and the second latch 230 are both located in the groove 211 .

[0072] It should be noted that, in this embodiment, assuming that the number of grooves 211 is m and the preset angle is α, then α = 360°*n / m, where n is a positive integer and 1≤n<m. Specifically, when m = 8, n = 1, then α = 45°; n = 2, then α = 90°; n = 3, then α = 135°; n = 4, then α = 180°. When m = 6, n = 1, then α = 60°; n = 2, then α = 120°; n = 3, then α = 180°.

[0073] Specifically, during use, assuming that initially, the limit shaft 270 is located at the first end of the arc groove 260, when the radial artery puncture point needs to be decompressed, first, the first sliding seat 160 is placed in the second working position A, and the second sliding seat 170 is placed in the first working position B, and then, the second knob 190 is turned in the reverse direction, and the second knob 190 drives the first latch 220 to rotate. Under the action of the blocking wall 201 of the groove 211 corresponding to the first latch 220, the first latch 220 drives the transmission disk 210 to rotate in the reverse direction, and the transmission disk 210 drives the second driving gear 171 to rotate in the reverse direction, and the second driving gear 171 drives the driven gear 150 to rotate in the forward direction, thereby achieving the purpose of driving the adjusting screw 140 to move toward the outside of the base plate 100, and then achieving the purpose of decompression. During this process, under the action of the guide wall 202 of the groove 211 corresponding to the second latch 230, the second latch 230 moves away from the axis of the transmission disk 210 and eventually moves out of the groove 211, so it will not affect the reverse rotation of the transmission disk 210.

[0074] When the limiting shaft 270 moves from the first end of the arc groove 260 to the second end of the arc groove 260, the second knob 190 cannot continue to rotate in the reverse direction, and then, the second knob 190 will be rotated in the forward direction. During this process, since the second pin 230 is inserted into the groove 211, under the action of the second pin 230 and the blocking wall 201 of the corresponding groove 211, the first pin 220 cannot drive the transmission disk 210 to rotate in the forward direction. Under the action of the guide wall 202 of the groove 211 corresponding to the first pin 220, the first pin 220 moves in the direction away from the axis of the transmission disk 210 and finally moves to the outside of the groove 211. Therefore, when the second knob 190 is rotated in the forward direction, the transmission disk 210 will not be driven to rotate in the forward direction.

[0075] When the limiting shaft 270 moves from the second end to the first end of the arc groove 260 , the second knob 190 returns to its original position, and the second knob 190 is rotated in the reverse direction again.

[0076] Repeat the above steps until the decompression is achieved.

[0077] The transmission assembly 200 of this structure is simple in structure and reasonably designed, so that the second knob 190 can only drive the second driving gear 171 to rotate in the reverse direction at a preset angle α each time, thereby avoiding the situation where the adjusting screw 140 moves too far due to a large angle of a single rotation, and the radial artery puncture point is caused to drop in pressure too quickly due to the large moving distance of the adjusting screw 140, thereby avoiding the situation where the radial artery puncture point is caused to drop in pressure too quickly due to the above reasons and causing bleeding, thereby achieving the purpose of avoiding secondary compression.

[0078] In one embodiment, a torsion spring (not shown in the drawings) is disposed at the rotation center of the second knob 190. In a natural state, the torsion spring has a tendency to rotate the second knob 190 in a positive direction. When in use, after each rotation of the second knob 190, the second knob 190 is loosened, and under the action of the reset torsion spring, the second knob 190 can rotate in a positive direction to return to its original position without the need for the medical staff to manually rotate the second knob 190 in a positive direction, thereby achieving the purpose of improving the rotation efficiency.

[0079] In one embodiment, the locking unit 300 includes a locking pull rod 310 , a guide groove 320 , and a third spring 330 .

[0080] The first end of the locking pull rod 310 is hinged to the base plate 100, and the second end has a sliding portion 311. The guide groove 320 is used to guide the sliding of the sliding portion 311, and the guide groove 320 is provided on the first sliding seat 160 or the second sliding seat 170. Specifically, the guide groove 320 of the locking unit 300 used to keep the first sliding seat 160 at the first working position A and the second working position A is provided on the first sliding seat 160, and conversely, the guide groove 320 of the locking unit 300 used to keep the second sliding seat 170 at the first working position B and the second working position B is provided on the second sliding seat 170.

[0081] Specifically, the guide groove 320 includes a slide-in and slide-out guide portion 321, a first guide portion 322, a temporary portion 323 and a second guide portion 324, and the slide-in and slide-out guide portion 321, the first guide portion 322, the temporary portion 323 and the second guide portion 324 are sequentially connected end to end to form a heart-shaped groove.

[0082] Among them, when the sliding part 311 slides along the sliding in and out guide part 321 and the first guide part 322 toward the temporary part 323, this process is the process of the first sliding seat 160 moving from the first working position A to the second working position A or the process of the second sliding seat 170 moving from the first working position B to the second working position B. When the sliding part 311 is temporarily positioned at the temporary part 323, the first sliding seat 160 is maintained at the second working position A or the second sliding seat 170 is maintained at the second working position B.

[0083] When the sliding portion 311 leaves the temporary portion 323 and slides along the second guide portion 324 toward and into the slide-out guide portion 321, this process is the process of the first sliding seat 160 moving from the second working position A to the first working position A or the process of the second sliding seat 170 moving from the second working position B to the first working position B. When the sliding portion 311 moves to the end of the slide-in and slide-out guide portion 321 away from the temporary portion 323, the first sliding seat 160 is maintained in the first position A or the second sliding seat 170 is maintained in the first working position B.

[0084] The third spring 330 is arranged on the first sliding seat 160 or the second sliding seat 170. Specifically, the third spring 330 of the locking unit 300 for maintaining the first sliding seat 160 in the first working position A and the second working position A is arranged on the first sliding seat 160. Conversely, the third spring 330 of the locking unit 300 for maintaining the second sliding seat 170 in the first working position B and the second working position B is arranged on the second sliding seat 170. In the natural state, the third spring 330 has a tendency to move the first sliding seat 160 from the second working position A to the first working position A or the first sliding seat 160 from the second working position B to the first working position B.

[0085] The locking unit 300 of this structure can achieve the purpose of moving the first sliding seat 160 from the first working position A to the second working position A and finally keeping it in the second working position A, or moving the second sliding seat 170 from the first working position B to the second working position B and finally keeping it in the second working position B, by pressing or pushing the first sliding seat 160 or the second sliding seat 170 once. The purpose of moving the first sliding seat 160 from the second working position A to the first working position A and finally keeping it in the first working position A, or moving the second sliding seat 170 from the second working position B to the first working position B and finally keeping it in the first working position B, can be achieved by pressing or pushing the first sliding seat 160 or the second sliding seat 170 again. The structure is simple and the operation is convenient.
