Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a spin-sensing hemostatic compressor. Background Art

[0002] The radial artery compressor is an air bag made of special polymer materials. It is based on the principle of hemodynamics. When the pressure on the limb artery wall is equal to the blood flow pressure, the blood flow will be interrupted, achieving the effect of hemostasis.

[0003] Postoperatively, the balloon pressure can be gradually reduced depending on the bleeding situation. Generally, 1 ml of air is released 2 hours after surgery, and 1 ml every hour thereafter, for a total of 4 times. When using a radial artery compressor, the buckle of the fixation strap should be carefully checked for looseness. After the final deflation, the radial artery compressor should not be removed immediately. Observe for 30 minutes until there is no bleeding before removing the radial artery compressor to avoid sudden decompression and blood flow shock that may cause severe bleeding. For patients with hypertension, chronic smoking, or excessive heparin use, the balloon pressure should be increased appropriately to extend the duration of compression. During decompression, the puncture site should be closely monitored for bleeding. If bleeding occurs, pressure should be increased immediately and the compression time should be appropriately extended. Existing radial artery compressors have a long compression duration, with compression times typically ranging from 4 to 6 hours. Furthermore, the compression force cannot be controlled, and excessive pressure often leads to hand swelling and even blisters. High venous pressure can cause bruising, and prolonged compression can even lead to nerve damage, increasing the incidence of radial artery occlusion. Releasing the pressure every 2 hours also significantly increases the workload of medical staff. In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0004] The purpose of the present invention is to automatically control the compression airbag decompression in stages according to the compression intensity, automatically complete the pressure adjustment process, and greatly reduce the workload of medical staff.

[0006] Furthermore, skin-friendly adhesive pads are fixedly provided on both sides of the outer surface of the positioning base, dust-proof stickers are adhered to the bottom ends of the skin-friendly adhesive pads, and a buffer pressure ring is fixedly provided on the bottom end surface of the positioning base.

[0007] Furthermore, the pressure regulating mechanism includes an extrusion shaft, a movable groove is opened inside the shell, the extrusion shaft is movably connected to the inner wall of the movable groove, a pressure plate is installed on the bottom end surface of the extrusion shaft, the bottom end surface of the pressure plate is in movably contact with the top end surface of the compression airbag, and the top end surface of the extrusion shaft is connected to a first rack.

[0008] Furthermore, the spin adjustment mechanism includes a torsion shaft and a linkage assembly, a limiting slot is provided inside the shell, the torsion shaft is movably installed on the inner wall of the limiting slot, one end of the torsion shaft extends to the inside of the shell and is connected to a driving gear, the linkage assembly and the driving gear are engaged with each other, the other end of the torsion shaft extends to the outside of the shell and is connected to a torsion block, a pointing protrusion is fixed on the outer surface of the torsion block, a dial corresponding to the pointing protrusion is fixed on the outer side of the shell, and a display light is installed on the top surface of the shell.

[0009] Furthermore, the linkage assembly includes a second rack, a movable long groove is opened on the top surface of the shell, the second rack is movably connected to the inner wall of the movable long groove, the second rack is engaged with the driving gear, a magnet block is fixed at one end of the second rack, and an electromagnet is fixed on the inner wall of the movable long groove facing the magnet block.

[0010] Furthermore, the control panel includes a data acquisition unit, a pressure sensing unit, a spin setting unit, a timing control unit and a spin adjustment unit; The data acquisition unit acquires the displacement data of the second rack through a displacement sensor provided on one side of the second rack, and acquires the pulse frequency data through a pulse sensing patch and sends the data to the pressure sensing unit and the spin setting unit; The pressure sensing unit obtains the surface squeezing force of the compression airbag through the pressure sensor installed on the inner wall of the expansion cavity and sends it to the spin setting unit. It also determines the standard value of the squeezing force based on the pulse frequency data, generates a squeezing signal and sends it to the display light; The spin setting unit obtains and processes the surface extrusion force and displacement data of the compression airbag, analyzes the displacement speed of the second rack based on the displacement data, establishes a correlation equation between the surface extrusion force and the displacement data based on the surface extrusion force, and substitutes a preset pressure relaxation frequency into the correlation equation to obtain the start and end times of a single pressure adjustment process; The timing control unit is used to record the start and end time of a single pressure regulation process and the start time of each pressure regulation in the total pressure regulation process; After receiving the spin adjustment instruction, the spin adjustment unit controls the electromagnet to be energized to make it magnetic, and drives the second rack to move under the action of magnetic attraction. After receiving the spin termination instruction, the electromagnet is controlled to be de-energized to complete the single pressure adjustment process.

[0011] Furthermore, the timing control unit includes a cycle timing module and a spin timing module, wherein the cycle timing module records the compression start time after obtaining the adjustment in place signal, and is set to send a spin adjustment instruction to the spin adjustment unit every 2 hours until the total pressure adjustment process is completed after 6-10 hours; the spin timing module records the spin start time after issuing the spin adjustment instruction, and sends a spin termination instruction to the spin adjustment unit when recording the spin start time to the spin termination time of the adjustment time to complete a single pressure adjustment process.

[0012] Furthermore, the specific process of generating the squeeze-in-place signal is as follows: S101, starting time t0 of manual adjustment when the medical staff starts to select the twist block, and acquiring real-time pulse frequency data Aw at intervals of period T1; As the manual adjustment amplitude increases, the compression degree of the compression balloon on the blood vessel increases, so the pulse rate decreases under its influence, and the pulse rate compression threshold Amin is higher than the pulse critical threshold when the compression is in place; S102. Obtain the pulse rate compression threshold Amin, compare the real-time pulse rate data Aw with Amin one by one, and if the real-time pulse rate data Aw is less than Amin, record the moment as the critical moment. Continue manual adjustment after the critical moment for a duration of nt, and obtain n real-time pulse rate data Aw in this process; S103, obtaining the surface extrusion force data Ft corresponding to each real-time pulse frequency data Aw, and calculating the pressure standard value ku according to the following formula: , where i = 1, 2, 3, ..., n. The pressure standard value ku indicates that the compression of the compression balloon on the blood vessel has reached the standard pressure value, and the pulse frequency at this time is within the normal compression range. The larger the pressure standard value ku, the closer the compression operation is to the standard. Conversely, the smaller the pressure standard value ku, the less the compression operation has reached the standard. S104: Obtain a preset pressure standard threshold value km. If the pressure standard value ku is greater than or equal to km, generate a squeeze-in-place signal. If the pressure standard value ku is less than km, no signal is generated and manual adjustment is required for a period of nt, and secondary calibration is performed until an extrusion signal is generated.

[0013] Furthermore, the process of calculating the start time and end time of a single pressure regulation process is as follows: S201, rotating the torsion block so that the pointing protrusion is aligned with the maximum value on the dial, at which point the compression plate squeezes the airbag to the maximum limit; S202. Connect an electromagnet to the circuit. Due to the magnetic attraction between the electromagnet and the magnet, the magnet moves along the movable slot, causing the second rack to move synchronously. The moment the electromagnet is connected to the circuit is defined as the starting time t1, and the second rack moves until it reaches its maximum displacement xm. The movement time tm of the second rack is recorded. S203. Calculate the average velocity vt of the second rack according to the displacement-time correlation formula: vt=xm / tm; S204, starting from the time t0 when the medical staff starts to select the torsion block, and obtaining m sets of surface extrusion force Ft and displacement data xt at intervals of period T2; S205. Establish a force-related coordinate system with the surface extrusion force Ft as the abscissa and the displacement data xt as the ordinate, and mark m groups of surface extrusion forces Ft in the force-related coordinate system to obtain m marked points P with coordinates P(xp, yp); S206. Connect several marking points P to obtain a force line L. According to the force line L, obtain the displacement data of the second rack and the related equation f (Ft) of the surface extrusion force: , where k1 is the proportional coefficient and b is a constant; S207. Obtain the preset pressure relaxation frequency Bn. It is known that the displacement of the second rack during a single pressure adjustment process is xb=xt / Bn. Substitute the real-time surface extrusion force data into the relevant equation f(Ft), output xt, and then obtain the single pressure adjustment duration. .

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The spin-sensing hemostatic compressor is provided with a skin-friendly adhesive gasket, which is attached to the skin surface near the puncture site, thereby fixing the positioning base at the puncture site. The torsion block drives the torsion shaft to rotate, and the driving gear rotates synchronously at this time, driving the first rack to move downward under the meshing action. The first rack drives the pressure plate to move downward, thereby squeezing the compression airbag, so that the compression airbag exerts pressure on the puncture site after being compressed, achieving the effect of compression and hemostasis.

[0015] 2. The spin-sensing hemostatic compressor controls the electromagnet to be energized at a fixed time through the control panel. After the electromagnet is energized, the magnetism of the electromagnet is opposite to that of the magnet block. Under the action of magnetic attraction, the second rack moves along the movable long groove. At this time, the driving gear rotates synchronously under the meshing action, thereby driving the first rack to move upward, relaxing the compression airbag and reducing the compression intensity. After multiple relaxations until the compression adjustment process is completed, wait for half an hour, then tear off the skin-friendly adhesive gasket and remove the radial artery spin-sensing hemostatic compressor.

[0016] 3. This spin-sensing hemostatic compressor determines the standard value of the extrusion force based on the pulse frequency data, generates an extrusion-in-place signal, and alerts the staff through a display light, reducing the influence of personal judgment and avoiding excessive compression. It can also automatically control the compression airbag decompression in stages according to the compression intensity through timing settings, automatically completing the pressure adjustment process without the need for manual monitoring by medical staff, greatly reducing the workload of medical staff.

A buffer pressure ring 6 is fixedly provided on the bottom surface of the positioning base 1. The medical staff first presses the hemostatic cotton on the puncture site, and then attaches the positioning base 1 to the hemostatic cotton so that the compression airbag 22 is directly above the puncture site. After tearing off the dust-proof sticker 5, the skin-friendly adhesive pad 4 is attached to the skin surface near the puncture site, thereby fixing the positioning base 1 at the puncture site.

[0021] The pressure regulating mechanism includes an extrusion shaft 8, a movable groove 7 is opened inside the shell 3, the extrusion shaft 8 is movably connected to the inner wall of the movable groove 7, and a pressure plate 9 is installed on the bottom surface of the extrusion shaft 8. The bottom surface of the pressure plate 9 is in movably contact with the top surface of the compression airbag 22, and the top surface of the extrusion shaft 8 is connected to the first rack 10.

[0022] The self-spin adjustment mechanism includes a torsion shaft 12 and a linkage assembly. A limiting groove 11 is provided inside the housing 3. The torsion shaft 12 is movably mounted on the inner wall of the limiting groove 11. One end of the torsion shaft 12 extends to the inside of the housing 3 and is connected to a driving gear 13. The linkage assembly and the driving gear 13 are meshed with each other. The other end of the torsion shaft 12 extends to the outside of the housing 3 and is connected to a torsion block 14. A pointing protrusion 15 is fixedly provided on the outer surface of the torsion block 14. A dial 16 corresponding to the pointing protrusion 15 is fixedly provided on the outer side of the housing 3. A display light 21 is installed on the top surface of the housing 3. Medical staff hold the torsion block 14 and rotate it to make the The torsion block 14 drives the torsion shaft 12 to rotate, and the driving gear 13 rotates synchronously at this time, and drives the first rack 10 to move downward under the meshing action. The first rack 10 drives the pressure plate 9 to move downward to squeeze the compression airbag 22, so that the compression airbag 22 applies pressure to the puncture site after being compressed, which has the effect of compressing and stopping bleeding. The deformed compression airbag 22 partially extends into the expansion cavity 2, and the driving gear 13 rotates while driving the second rack 17 to move synchronously in the moving long slot 18 until it is adjusted to the appropriate compression level. At this time, the compression level is displayed by the indication of the pointing protrusion 15 on the dial 16.

[0023] The linkage assembly includes a second rack 17, and a movable long groove 18 is provided on the top surface of the shell 3. The second rack 17 is movably connected to the inner wall of the movable long groove 18. The second rack 17 is meshed with the driving gear 13. A magnet block 19 is fixed at one end of the second rack 17, and an electromagnet 20 is fixed on the inner wall of the movable long groove 18, which is opposite to the magnet block 19. The electromagnet 20 is energized by timing control through the control panel. After the electromagnet 20 is energized, the magnetism carried by the electromagnet 20 is opposite to the magnetism carried by the magnet block 19. Under the action of magnetic attraction, the second rack 17 moves along the movable long groove 18. At this time, the driving gear 13 rotates synchronously under the meshing action, thereby driving the first rack 10 to move upward, relaxing the compression airbag 22, reducing the compression intensity, and completing the compression adjustment process through multiple relaxations. After waiting for half an hour, tear off the skin-friendly adhesive gasket 4 and remove the radial artery spin-sensing hemostatic compressor.

[0024] The working principle is as follows: when in use, the medical staff first presses the hemostatic cotton on the puncture site, then attaches the positioning base 1 to the hemostatic cotton so that the compression airbag 22 is directly above the puncture site. After tearing off the dustproof sticker 5, the skin-friendly adhesive pad 4 is attached to the skin surface near the puncture site, thereby fixing the positioning base 1 at the puncture site. The medical staff holds the torsion block 14 and rotates it, causing the torsion block 14 to drive the torsion shaft 12 to rotate. At this time, the driving gear 13 rotates synchronously, driving the first rack 10 to move downward under the meshing action. The first rack 10 drives the pressure plate 9 to move downward, thereby squeezing the compression airbag 22. When the compression airbag 22 is compressed, it applies pressure to the puncture site, achieving the effect of compression and hemostasis. The deformed compression airbag 22 partially extends into the expansion cavity 2. The driving gear 13 rotates while driving the second rack 17 to move synchronously in the movable long slot 18 until it is adjusted to the appropriate compression level. At this time, the compression level is displayed by the indication of the pointing protrusion 15 on the dial 16, and then the electromagnet 20 is energized by timing control through the control panel. After the electromagnet 20 is energized, the magnetism carried by the magnet block 19 is opposite to that of the magnet block 19. Under the action of magnetic attraction, the second rack 17 moves along the movable long slot 18. At this time, the driving gear 13 rotates synchronously under the meshing action, and then drives the first rack 10 to move upward, relaxes the compression airbag 22, and reduces the compression intensity. After multiple relaxations until the compression adjustment process is completed, wait for half an hour, tear off the skin-friendly adhesive gasket 4, and remove the radial artery spin-sensing hemostatic compressor.

[0025] Example 2: like Figure 5 As shown, the spin-sensing hemostatic compressor includes a positioning base 1 and a control panel, and the control panel includes a data acquisition unit, a pressure sensing unit, a spin setting unit, a timing control unit and a spin adjustment unit; The data acquisition unit acquires the displacement data of the second rack 17 through a displacement sensor provided on one side of the second rack 17, and acquires the pulse frequency data through a pulse sensing patch and sends it to the pressure sensing unit and the spin setting unit; The pressure sensing unit obtains the surface squeezing force of the compression airbag 22 through the pressure sensor provided on the inner wall of the expansion cavity 2 and sends it to the spin setting unit. The pressure sensing unit determines the standard value of the squeezing force based on the pulse frequency data and generates a squeezing-in-place signal and sends it to the display light 21. The pressure sensor is a known prior art, and its specific position can be adjusted according to the structure and is not shown in the figure. The pulse sensing patch is also a known prior art. Medical personnel attach the pulse sensing patch to the pulse sensing position at the puncture site. Its specific position is adjusted according to the puncture site and is also not shown in the figure. The spin setting unit obtains and processes the surface extrusion force and displacement data of the compression airbag 22, analyzes the displacement speed of the second rack 17 based on the displacement data, and establishes a correlation equation between the surface extrusion force and the displacement data based on the surface extrusion force. The preset pressure relaxation frequency is substituted into the correlation equation to obtain the start and end times of a single pressure adjustment process; The timing control unit is used to record the start and end time of a single pressure regulation process and the start time of each pressure regulation in the total pressure regulation process; After receiving the spin adjustment instruction, the spin adjustment unit controls the electromagnet 20 to be energized to make it magnetic, and drives the second rack 17 to move under the action of magnetic attraction. After receiving the spin termination instruction, the electromagnet 20 is controlled to be deenergized to complete the single pressure adjustment process.

[0026] The timing control unit includes a cycle timing module and a spin timing module. The cycle timing module records the compression start time after obtaining the adjustment in place signal, and is set to send a spin adjustment instruction to the spin adjustment unit every 2 hours until the total pressure adjustment process is completed after 6-10 hours; the spin timing module records the spin start time after issuing the spin adjustment instruction, and sends a spin termination instruction to the spin adjustment unit when recording the spin start time to the spin termination time of the adjustment time to complete a single pressure adjustment process.

[0027] The specific process of generating the squeeze-in-place signal is as follows: S101, the medical staff starts to select the twist block 14 as the manual adjustment starting time t0, and obtains real-time pulse frequency data Aw at intervals of period T1; As the amplitude of manual adjustment increases, the compression degree of the compression airbag 22 on the blood vessel increases, so the pulse frequency decreases under its influence, and the pulse frequency compression threshold Amin is higher than the pulse critical threshold when the compression is in place; S102. Obtain the pulse rate compression threshold Amin, compare the real-time pulse rate data Aw with Amin one by one, and if the real-time pulse rate data Aw is less than Amin, record the moment as the critical moment. Continue manual adjustment after the critical moment for a duration of nt, and obtain n real-time pulse rate data Aw in this process; S103, obtaining the surface extrusion force data Ft corresponding to each real-time pulse frequency data Aw, and calculating the pressure standard value ku according to the following formula: , where i = 1, 2, 3, ..., n. The pressure standard value ku indicates that the compression of the compression balloon 22 on the blood vessel has reached the standard pressure value, and the pulse frequency at this time is within the normal compression range. The larger the pressure standard value ku, the closer the compression operation is to the standard. Conversely, the smaller the pressure standard value ku, the less the compression operation has reached the standard. S104: Obtain a preset pressure standard threshold value km. If the pressure standard value ku is greater than or equal to km, generate a squeeze-in-place signal. If the pressure standard value ku is less than km, no signal is generated and manual adjustment is required for a period of nt, and secondary calibration is performed until an extrusion signal is generated.

[0028] The process of calculating the start and end times of a single pressure regulation process is as follows: S201, rotating the torsion block 14 so that the pointing protrusion is aligned with the maximum value on the dial 16, at which time the squeezing plate squeezes the airbag 22 to the maximum limit; S202. Connect the electromagnet 20 to the circuit. Due to the magnetic attraction between the electromagnet 20 and the magnet block 19, the magnet block 19 is driven to move along the movable slot 18, causing the second rack 17 to move synchronously. The time when the electromagnet 20 is connected to the circuit is defined as the starting time t1. The movement time tm of the second rack 17 is recorded until the second rack 17 reaches the maximum displacement xm. S203, calculating the average velocity vt of the second rack 17 according to the displacement-time correlation formula: vt=xm / tm; S204, starting from the time t0 when the medical staff starts to select the torsion block 14, and acquiring m sets of surface extrusion force Ft and displacement data xt at intervals of period T2; S205. Establish a force-related coordinate system with the surface extrusion force Ft as the abscissa and the displacement data xt as the ordinate, and mark m groups of surface extrusion forces Ft in the force-related coordinate system to obtain m marked points P with coordinates P(xp, yp); S206. Connect several marking points P to obtain a force line L. According to the force line L, obtain the displacement data of the second rack 17 and the related equation f (Ft) of the surface extrusion force: , where k1 is the proportional coefficient and b is a constant; S207, obtain the preset pressure relaxation frequency Bn, it can be known that the displacement of the second rack 17 during a single pressure adjustment process is xb=xt / Bn, substitute the real-time surface extrusion force data into the relevant equation f(Ft), output xt, and then obtain the single pressure adjustment duration .

[0029] The present invention determines the standard value of the extrusion force based on the pulse frequency data, and after generating the extrusion in place signal, reminds the staff through the display light 21, reducing the influence of personal judgment to avoid excessive compression. In addition, the present invention can automatically control the compression airbag 22 to decompress in stages according to the compression intensity through timing settings, automatically completing the pressure adjustment process without the need for manual monitoring by medical staff, greatly reducing the workload of medical staff.

[0030] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each set of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.
