Description

Technical Field

[0001] The present invention relates to the field of pulse compression equipment, and in particular to a consumable pulse compression component and a pulse compression device. Background Art

[0002] In some cases, when medical staff draw blood from patients, they will use a pulse compressor instead of a tourniquet to achieve the pulse compression effect on the patient's arm. In this way, medical staff do not need to manually tighten or untie the pulse compression belt, which reduces the labor intensity of medical staff to a certain extent.

[0003] Existing compression devices generally have a compression coil and a feeding mechanism. The compression coil can perform pulse compression on the patient's arm, and the feeding mechanism can deliver sanitary consumables to the compression coil. The sanitary consumables are used to separate the patient's arm from the compression coil. Every time a patient is replaced, a section of consumables is replaced to avoid cross infection. However, the adjustable size range of the compression coil is limited. When the patient's arm is too thin or too thick, it cannot be used normally and has poor adaptability.

[0004] In summary, how to overcome the above-mentioned defects of the existing pulse compressor is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a consumable pulse compression assembly and a pulse compressor to alleviate the technical problems of the pulse compressor in the prior art, such as the limited adjustable size range and poor adaptability.

[0006] The consumables compression pulse assembly provided by the present invention comprises a feeding mechanism and a winding mechanism. The feeding mechanism is used to supply sanitary consumables to the winding mechanism and can self-lock when the feeding is stopped.

[0007] The winding mechanism includes a driver, a mounting seat, a driving shaft and a driven shaft, the driver and the mounting seat are fixedly arranged, the driver is connected to the driving shaft in transmission, and is used to drive the driving shaft to rotate around a rotation centerline; the driven shaft is a damping shaft, the driven shaft is mounted on the mounting seat, the rotation centerline of the driving shaft coincides with the rotation centerline of the driven shaft, the driving shaft and the driven shaft are arranged in a direction perpendicular to the rotation centerline, and there is a gap between the driving shaft and the driven shaft.

[0008] Preferably, as an implementable embodiment, the consumable compression pulse assembly further includes a V-shaped support mold, and the V-shaped support mold is located above the winding mechanism, and the opening of the V-shaped support mold faces upward.

[0011] Preferably, as an implementable embodiment, the driven shaft includes a shaft body and a damping hinge, one end of the damping hinge is mounted on the mounting seat, and the other end of the damping hinge is connected to the shaft body.

[0012] Preferably, as an implementable embodiment, a bearing is installed between the shaft body and the mounting seat.

[0013] Preferably, as an implementable embodiment, the consumable compression pulse assembly also includes a controller, the driver is electrically connected to the controller, and the controller is used to control the driver to drive the driving shaft to rotate forward one circle after the sanitary consumable enters the gap.

[0014] Preferably, as an implementable embodiment, the consumable pressure pulse assembly also includes a pressure pulse switch, and the pressure pulse switch is electrically connected to the controller, and the controller is used to control the driver to drive the active shaft to rotate forward when the pressure pulse switch is turned on; the controller is used to control the driver to stop running when the load borne by the driver reaches a predetermined value.

[0015] Preferably, as an implementable embodiment, the controller starts timing when the driver stops driving the driving shaft to rotate forward, and controls the driver to drive the driving shaft to rotate reversely after the timing ends;

[0016] Alternatively, the consumable compression pulse assembly further includes a pressure relief switch, which is electrically connected to the controller, and the controller is used to control the driver to drive the active shaft to reverse after the pressure relief switch is turned on.

[0017] Preferably, as an implementable embodiment, the driver is a motor, the consumable compression pulse assembly also includes a fixedly arranged zero calibration photoelectric switch, and a sensing rod is fixedly connected to the active shaft.

[0018] The sensing rod can trigger the zeroing photoelectric switch when the orientation of the driving shaft is the same as the initial state. The zeroing photoelectric switch is electrically connected to the controller. The controller is used to accumulate the number of triggering times of the zeroing photoelectric switch and to obtain the rotation angle of the encoder of the motor.

[0019] Correspondingly, the present invention also provides a pulse compressor, which includes the above-mentioned consumable pulse compressor assembly.

[0020] The consumable pulse compression assembly and the pulse compression device provided by the present invention have the following beneficial effects:

[0021] The consumables compression pulse assembly provided by the present invention is mainly composed of a feeding mechanism and a winding mechanism, and the feeding mechanism can supply sanitary consumables to the winding mechanism. The winding mechanism includes a driver, a mounting seat, a driving shaft and a driven shaft, the driver and the mounting seat are fixedly arranged, the driver is connected to the driving shaft in a transmission manner to drive the driving shaft to rotate around the rotation center line; the above-mentioned driven shaft is a damping shaft, and the driven shaft is installed on the mounting seat, the rotation center line of the driving shaft coincides with the rotation center line of the driven shaft, the driving shaft and the driven shaft are arranged in a direction perpendicular to the above-mentioned rotation center line, and a gap is left between the driving shaft and the driven shaft.

[0022] When pulse compression is needed, start the feeding mechanism, and use the feeding mechanism to supply sanitary consumables to the winding mechanism, and insert the end of the sanitary consumables into the gap between the driving shaft and the driven shaft; then, start the driver, and use the driver to drive the driving shaft to rotate forward around the rotation center line (it should be noted that the forward rotation here means that the edge of the driving shaft will rotate toward the pulse compression area after passing through the side of the incoming material of the sanitary consumables). At this time, the driven shaft remains stationary, so that the gap between the driving shaft and the driven shaft will become narrower and narrower until the driving shaft and the driven shaft clamp the sanitary consumables. After that, the driver continues to drive the driving shaft to rotate forward, and the driven shaft will rotate around its rotation center line under the push of the driving shaft. Because the driven shaft is a damping shaft, the driven shaft will not separate from the driving shaft during the process of the driving shaft pushing the driven shaft to rotate, that is, the driving shaft and the driven shaft rotate synchronously around their rotation center lines, and the driving shaft and the driven shaft will apply a certain extrusion force to the sanitary consumables from both sides. In this way, during the process of the driving shaft pushing the driven shaft to rotate, the end of the sanitary consumables can be fixed in the gap between the driving shaft and the driven shaft, and during the rotation of the driving shaft, the sanitary consumables will be wound around the periphery of the driving shaft and the driven shaft; when the sanitary consumables are wound for more than half a circle (the specific number of winding circles can be selected according to needs), the driver stops running and the feeding mechanism continues to feed. Because the edge of the driving shaft will rotate toward the pressure pulse area after passing through the side of the incoming material of the sanitary consumables, the sanitary consumables will form a ring structure in the pressure pulse area after the driver stops running, and the patient's arm can be extended into the ring structure surrounded by the sanitary consumables. Afterwards, the feeding mechanism stops feeding and self-locks, and restarts the driver. The driver drives the driving shaft to continue to rotate forward, so that the part of the sanitary consumables that forms the ring structure can be wound around the periphery of the driving shaft and the driven shaft. As a result, the ring-shaped sanitary consumables will gradually shrink, and eventually wrap the patient's arm and generate a certain pressure between the patient's arm and the patient's arm. When the pressure pulse force is reached, the driver stops running, and thus, the sanitary consumables can be used to achieve the purpose of pressure pulse.

[0023] When the puncture is completed, the driver is started and the driver is used to drive the driving shaft to reverse (it should be noted that the reversal here means that the edge of the driving shaft will rotate in the direction away from the pressure pulse area after passing through the side of the incoming material of the sanitary consumables). At this time, the driven shaft will follow the driving shaft to rotate in the opposite direction. During this process, the annular sanitary consumables will gradually expand, so that the patient's arm can be smoothly pulled out of the annular sanitary consumables; after the driven shaft is reversed to the initial state, the driving shaft rotates forward until it returns to its initial position. During this process, the driven shaft no longer rotates with the driving shaft, but stays in the initial position. At this time, the gap between the driving shaft and the driven shaft will open, so that the end of the sanitary consumables will lose the clamping force of the driving shaft and the driven shaft, and the used sanitary consumables can be smoothly removed to prepare for the next pressure pulse.

[0024] Therefore, the consumable pulse compression assembly provided by the present invention has an annular sanitary consumable with a wide adjustable range of size and strong adaptability, and can basically meet the pulse compression needs of all patients.

[0025] The pulse compressor provided by the present invention includes the above-mentioned consumable pulse compressor assembly.

[0026] Therefore, the pulse compression device provided by the present invention has all the advantages of the above-mentioned consumable pulse compression components, has a wide range of adjustable sizes, has strong adaptability, and can basically meet the pulse compression needs of all patients.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0042] See also Figure 1 - Figure 4This embodiment provides a consumables compression assembly, which is mainly composed of a feeding mechanism 100 and a winding mechanism 200. The feeding mechanism 100 can supply sanitary consumables to the winding mechanism 200. The winding mechanism 200 includes a driver 210, a mounting seat 220, a driving shaft 230 and a driven shaft 240. The driver 210 and the mounting seat 220 are fixedly arranged. The driver 210 is connected to the driving shaft 230 in a transmission manner to drive the driving shaft 230 to rotate around the rotation center line; the above-mentioned driven shaft 240 is a damping shaft, and the driven shaft 240 is installed on the mounting seat 220. The rotation center line of the driving shaft 230 coincides with the rotation center line of the driven shaft 240. The driving shaft 230 and the driven shaft 240 are arranged in a direction perpendicular to the above-mentioned rotation center line, and a gap 250 is left between the driving shaft 230 and the driven shaft 240.

[0043] When pulse compression is needed, start the feeding mechanism 100, and use the feeding mechanism 100 to supply sanitary consumables to the winding mechanism 200, and insert the end of the sanitary consumables into the gap 250 between the driving shaft 230 and the driven shaft 240; then, start the driver 210, and use the driver 210 to drive the driving shaft 230 to rotate forward around the rotation center line (it should be noted that the forward rotation here means that the edge of the driving shaft 230 will rotate toward the pulse compression area after passing through the side of the incoming material of the sanitary consumables). At this time, the driven shaft 240 remains stationary, so that the gap 250 between the driving shaft 230 and the driven shaft 240 will become narrower and narrower until the driving shaft 230 and the driven shaft 240 clamp the sanitary consumables. After that, the driver 210 continues to drive the driving shaft 230 to rotate forward, and the driven shaft 240 will rotate around its rotation center line under the push of the driving shaft 230. Because the driven shaft 240 is a damping rotating shaft, the driven shaft 240 will not separate from the driving shaft 230 during the process of the driving shaft 230 pushing the driven shaft 240 to rotate, that is, the driving shaft 230 and the driven shaft 240 rotate synchronously around their rotation center lines, and the driving shaft 230 and the driven shaft 240 will apply a certain extrusion force to the sanitary consumables from both sides. In this way, during the process of the driving shaft 230 pushing the driven shaft 240 to rotate, the end of the sanitary consumables can be fixed in the gap 250 between the driving shaft 230 and the driven shaft 240, and during the rotation of the driving shaft 230, the sanitary consumables will be wound around the periphery of the driving shaft 230 and the driven shaft 240; when the sanitary consumables are wound for more than half a circle (the specific number of winding circles can be selected according to needs), the driver 210 stops running and the feeding mechanism 100 continues to feed. Because the edge of the driving shaft 230 will rotate toward the pressure pulse area after passing through the side of the incoming material of the sanitary consumables, after the driver 210 stops running, the sanitary consumables will form a ring structure in the pressure pulse area, and the patient's arm can be extended into the ring structure surrounded by the sanitary consumables. Afterwards, the feeding mechanism 100 stops feeding and self-locks, and restarts the driver 210. The driver 210 drives the driving shaft 230 to continue to rotate forward, so that the part of the sanitary consumables that forms the ring structure can be wound around the driving shaft 230 and the driven shaft 240. As a result, the ring-shaped sanitary consumables will gradually shrink, and eventually wrap the patient's arm and generate a certain pressure between the patient's arm and the patient's arm. When the pressure pulse strength is reached, the driver 210 stops running, so that the sanitary consumables can be used to achieve the purpose of pressure pulse.

[0044] After the puncture is completed, the driver 210 is started, and the driver 210 is used to drive the driving shaft 230 to reverse (it should be noted that the reversal here means that the edge of the driving shaft 230 will rotate in the direction away from the pressure area after passing through the side of the incoming material of the sanitary consumables). At this time, the driven shaft 240 will follow the driving shaft 230 to rotate in the opposite direction. During this process, the annular sanitary consumables will gradually expand, so that the patient's arm can be smoothly drawn out of the annular sanitary consumables; after the driven shaft 240 is reversed to the initial state, the driving shaft 230 rotates forward until it returns to its initial position. During this process, the driven shaft 240 no longer rotates with the driving shaft 230, but stays in the initial position (see Figure 2 and Figure 4 ), at this time, the gap 250 between the driving shaft 230 and the driven shaft 240 will open, so that the end of the sanitary consumables will lose the clamping force of the driving shaft 230 and the driven shaft 240, and the used sanitary consumables can be smoothly removed to prepare for the next pulse compression.

[0045] Therefore, the consumable pulse compression assembly provided in this embodiment has a ring-shaped sanitary consumable with a wide adjustable range of size and strong adaptability, which can basically meet the needs of all patients.

[0046] Specifically, a V-shaped support mold 500 with an upward opening can be added above the winding mechanism 200. In this way, after the driver 210 drives the active shaft 230 to rotate one circle and stops, the continuously supplied sanitary consumables will enter the space surrounded by the V-shaped support mold 500. Under the support of the V-shaped support mold 500, the sanitary consumables are not easy to collapse. In other words, the V-shaped support mold 500 can make the ring formed by the sanitary consumables closer to a circle, so that the patient's arm can be more smoothly extended into the ring formed by the sanitary consumables.

[0047] Specifically, see Figure 1 A feeding channel 300 can be further provided between the feeding mechanism 100 and the winding mechanism 200. The feeding mechanism 100 can feed into the feeding port of the feeding channel 300, that is, the sanitary consumables can enter the feeding channel 300 from the feeding port of the feeding channel 300, and can move along the feeding channel 300, and finally extend out from the discharge port of the feeding channel 300; when the driving shaft 230 and the driven shaft 240 are both in the initial position, the gap 250 between the driving shaft 230 and the driven shaft 240 will be opposite to the discharge port of the feeding channel 300, so that after the sanitary consumables extend out from the discharge port of the feeding channel 300, they can smoothly extend into the gap 250 between the driving shaft 230 and the driven shaft 240, without the need for human intervention, and are easy to use.

[0048] Further, see Figure 2The above-mentioned active shaft 230 has a first arc surface part 231, and the first arc surface part 231 faces the feeding channel 300 when the driven shaft 240 is reset, and the first arc surface part 231 is inclined from the inside of the slit 250 to the outside toward the side away from the driven shaft 240; correspondingly, the above-mentioned driven shaft 240 has a second arc surface part 241, and the second arc surface part 241 faces the feeding channel 300 when the driven shaft 240 is reset, and the second arc surface part 241 is inclined from the inside of the slit 250 to the outside toward the side away from the driven shaft 240. In this way, in the initial state, the slit 250 will form an expansion in the direction of the incoming sanitary consumables, so that the sanitary consumables can enter the slit 250 more smoothly and with higher reliability.

[0049] In the specific structure of the driven shaft 240 , a shaft body and a damping hinge may be provided, one end of the damping hinge is mounted on the mounting seat 220 , and the other end of the damping hinge is connected to the shaft body.

[0050] Preferably, a bearing may be installed between the shaft body and the mounting seat 220 , so that the bearing can be used to bear the tensile force and improve the structural stability.

[0051] A controller can be added to the specific structure of the consumable compression assembly to electrically connect the above-mentioned driver 210 to the controller. After the sanitary consumable enters the gap 250 between the driving shaft 230 and the driven shaft 240, the driver 210 can be controlled to rotate forward one circle. In this way, a circle of clean sanitary consumables that have not been in contact with the patient will be wrapped around the outer periphery of the driving shaft 230 and the driven shaft 240, so that the sanitary consumables that have been in contact with the patient subsequently can be wrapped around the previous circle of sanitary consumables. Therefore, the sanitary consumables are not easy to contaminate the driving shaft 230 and the driven shaft 240, and further, cross infection is not easy to occur between patients.

[0052] Whether the sanitary consumables have extended into the gap 250 between the driving shaft 230 and the driven shaft 240 can be determined based on the length of the sanitary consumables output by the feeding mechanism 100. That is, when the length of the sanitary consumables output by the feeding mechanism 100 reaches a preset length, the controller determines that the sanitary consumables have extended into the gap 250 between the driving shaft 230 and the driven shaft 240. At this time, the driver 210 can be controlled to drive the driving shaft 230 to rotate forward one circle.

[0053] In the specific structure of the consumable pulse compression assembly provided in this embodiment, a pulse compression switch can be set, and the pulse compression switch is electrically connected to the controller. When the patient's arm is inserted into the annular sanitary consumable and is in a suitable pulse compression position, the pulse compression switch can be turned on. At this time, the controller will control the driver 210 to drive the active shaft 230 to rotate forward according to the signal of the pulse compression switch being turned on, so as to achieve the purpose of pulse compression. During the forward rotation of the driver 210, the controller will obtain the load borne by the driver 210 in real time, and the load can be used to reflect the pulse compression strength of the sanitary consumable on the patient's arm. When the load borne by the driver 210 reaches a predetermined value, the pulse compression strength of the sanitary consumable on the patient's arm reaches the required strength. At this time, the controller will control the driver 210 to stop running. In this way, there is no need to manually judge the pulse compression strength, which is very intelligent.

[0054] As an implementable embodiment, the controller starts timing when the driver 210 stops driving the active shaft 230 to rotate forward, and controls the driver 210 to drive the active shaft 230 to reverse after the timing ends. That is to say, after completing the pulse compression, the controller will set aside a period of time for puncture, after which the controller will automatically determine that the puncture is completed, and control the driver 210 to drive the active shaft 230 to reverse, so that the annular sanitary consumables can release the patient's arm.

[0055] As another possible implementation method, a pressure relief switch can be added and electrically connected to the controller. After the puncture is completed, the pressure relief switch can be turned on. Thereafter, the controller controls the driver 210 to drive the active shaft 230 to reverse so that the annular sanitary consumable can release the patient's arm.

[0056] A motor may be used as the driver 210 .

[0057] A reduction box 260 may be provided between the motor and the driving shaft 230 , and the output shaft of the motor and the input end gear of the reduction box 260 may be coaxially fixed, and the output end gear of the reduction box 260 may be coaxially fixed with the driving shaft 230 .

[0058] Preferably, a zeroing photoelectric switch 400 can be added to the consumable compression pulse assembly provided in the present embodiment, and the zeroing photoelectric switch 400 is fixedly set. At the same time, a sensing rod 270 is fixedly connected to the active shaft 230. When the orientation of the active shaft 230 is the same as its initial state, the sensing rod 270 can trigger the zeroing photoelectric switch 400. That is to say, the zeroing photoelectric switch 400 is triggered once every time the motor drives the active shaft 230 to rotate one circle; the above-mentioned zeroing photoelectric switch 400 is electrically connected to the controller so that the controller can accumulate the number of triggering times of the zeroing photoelectric switch 400 and obtain the rotation angle of the encoder of the motor.

[0059] During the forward rotation of the motor, if the zeroing photoelectric switch 400 is triggered N times, then during the reverse rotation of the motor, when the zeroing photoelectric switch 400 is triggered N+1 times, the controller can determine that the active shaft 230 is reset. At this time, the controller continues to control the motor to reverse and obtains the rotation angle of the motor encoder; when the driven shaft 240 is reset under the push of the active shaft 230, the rotation angle of the motor encoder just reaches the first preset angle. At this time, the controller controls the motor to rotate forward and obtains the rotation angle of the motor encoder again. During this process, the driven shaft 240 no longer follows the active shaft 230 to rotate forward, but remains in the reset state; when the zeroing photoelectric switch 400 is triggered N+2 times, the controller can determine that the active shaft 230 is reset again. At this time, the controller controls the motor to stop running, and the automatic reset of the active shaft 230 and the driven shaft 240 can be completed, with a high degree of automation.

[0060] This embodiment also provides a pulse compressor, which includes the above-mentioned consumable pulse compressor assembly.

[0061] Therefore, the pulse compression device provided in this embodiment has all the advantages of the above-mentioned consumable pulse compression components, has a wide range of adjustable sizes, has strong adaptability, and can basically meet the pulse compression needs of all patients.

[0062] In summary, the present invention discloses a consumable pulse compression assembly and a pulse compression device, which overcomes many technical defects of traditional pulse compression devices. The consumable pulse compression assembly and the pulse compression device provided in this embodiment have a wide range of adjustable sizes and strong adaptability, and can basically meet the pulse compression needs of all patients.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
