Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an exhaust device for an electronic perfusion device. Background Art

[0002] Hemoperfusion is a treatment method that introduces the patient's blood into a perfusion device filled with solid adsorbents to remove certain exogenous or endogenous toxins, and then returns the purified blood to the body. Hemoperfusion is generally used to treat acute and chronic drug poisoning, uremia and other diseases. The combined application of hemoperfusion and hemodialysis is a necessary means for the treatment of chronic renal failure combined with acute drug poisoning, and can also be used to treat toxic acute renal failure caused by poisons and drug poisoning.

[0003] This method is a treatment method in which the patient's blood is introduced into a perfusion device containing solid adsorbent to remove certain exogenous or endogenous toxins, and the purified blood is returned to the body. When using the perfusion device, the perfusion device must be pre-flushed, and the air in the perfusion device must be exhausted during the pre-flushing.

[0004] At present, the perfusion device is equipped with a percussion hammer. The method of purging bubbles is to rely on manual percussion to expel the bubbles in the perfusion device. The purging time is long, and the force and percussion position of the percussion hammer cannot be accurately controlled during operation. If the percussion force is too small, there may be a risk of not completely purging the bubbles, and if the percussion force is too large, there is a risk of damaging the sealing quality of the perfusion device. In addition, by visually observing the bubble removal, it is generally required that there are no residual bubbles or the residual single bubble is less than 5mm, but due to the uncertainty of subjective observation, there is a risk of not completely purging the bubbles. Summary of the invention

[0005] The embodiment of the present application provides an exhaust device for an electronic perfusion device, which can solve the problem of low efficiency of manual operation when removing bubbles by manual beating.

[0006] An embodiment of the present application provides an electronic cartridge exhaust device, which includes a base, a mounting unit, a clamping unit and a vibration exhaust unit. The mounting unit is arranged on the base, the mounting unit is arranged at one end of the base, and the mounting unit is used to be fixed on a column of a dialysis machine; the clamping unit is arranged at the other end of the base, and the clamping unit is used to clamp and fix the cartridge; the vibration exhaust unit includes a posture adjustment component and a vibration component, the posture adjustment component is arranged between the base and the clamping unit, the posture adjustment component is used to drive the clamping unit to swing back and forth in the left and right directions at a preset angle, and the vibration component is arranged on the clamping unit, and is used to drive the cartridge to vibrate to remove bubbles in the cartridge.

[0007] In this scheme, through the setting of the mounting unit, the electronic cartridge exhaust device can be installed and fixed on the column of the dialysis machine through the mounting unit, so as to realize the detachable installation of the electronic cartridge exhaust device. The clamping unit is arranged at the other end of the base, and the clamping unit can realize the clamping and fixing of the cartridge, and the cartridge is clamped and fixed by the clamping force, and the cartridge installation stability and reliability are high, which is convenient for the disassembly and installation of the cartridge.

In addition, the posture adjustment component can drive the cartridge on the clamping unit to swing back and forth at a preset angle in the left and right directions, so that the cartridge can realize the reciprocating switching of the angle between the inclined state and the vertical state under the cooperation of the posture adjustment component and the vibration component. Since the cartridge swings left and right, the fluidity of the bubbles in the cartridge can be increased, so that the bubbles can be separated and discharged out of the cartridge more quickly. Therefore, through the setting of the vibration component and the posture adjustment component, there is no need to manually use a hammer to knock on the perfusion device to remove bubbles.

[0009] In the above technical solution, through the setting of the bubble monitoring unit, the bubble sensor in the bubble monitoring unit can monitor the bubbles in the water outlet pipeline of the perfusion device, which can play a role in monitoring the exhaust progress of the perfusion device. When the number of bubbles in the perfusion device is less than the first threshold value, that is, when the bubbles in the perfusion device are almost completely removed with the saline or the amount of bubbles is small, it means that the exhaust work of the perfusion device is nearly completed, so the vibration exhaust unit can be automatically controlled to stop working, which is convenient for further perfusion operations. When the bubble sensor detects that the bubbles in the outlet pipeline of the perfusion device are greater than the second threshold value, it means that the amount of bubbles in the perfusion device is large and / or the bubbles are large, the vibration exhaust unit works or continues to work, and the bubbles in the perfusion device are exhausted to the required level, which does not require medical staff to pay attention all the time, reduces the workload of medical staff, and has a high degree of automation.

[0035] Example The present application embodiment provides an electronic cartridge exhaust device, please refer to Figures 1 to 5 The electronic cartridge exhaust device 100 includes a base 10, a mounting unit 20, a clamping unit 30 and a vibration exhaust unit 40. The mounting unit 20 is arranged on the base 10, and the mounting unit 20 is arranged at one end of the base 10. The mounting unit 20 is used to be fixed on the column of the dialysis machine; the clamping unit 30 is arranged at the other end of the base 10, and the clamping unit 30 is used to clamp and fix the cartridge (not shown in the figure); the vibration exhaust unit 40 includes a posture adjustment component 41 and a vibration component 42. The posture adjustment component 41 is arranged between the base 10 and the clamping unit 30. The posture adjustment component 41 is used to drive the clamping unit 30 to swing back and forth in the left and right directions at a preset angle. The vibration component 42 is arranged on the clamping unit 30, and is used to drive the cartridge to vibrate to remove bubbles in the cartridge.

[0036] In this solution, by setting the mounting unit 20, the electronic cartridge exhaust device 100 can be installed and fixed on the column of the dialysis machine through the mounting unit 20, so as to realize the detachable installation of the electronic cartridge exhaust device. The clamping unit 30 is set at the other end of the base 10, and the clamping unit 30 can realize the clamping and fixing of the cartridge, and the cartridge is clamped and fixed by the clamping force. The cartridge installation stability and reliability are high, and the cartridge is easy to disassemble and install. By setting the vibration exhaust unit 40, the vibration exhaust unit 40 includes a posture adjustment component 41 and a vibration component 42. By using the vibration component 42 set on the clamping unit 30, the bubbles in the cartridge are vibrated, and the bubbles move upward under the action of vibration and are discharged with the saline, thereby removing the bubbles in the cartridge. In addition, the posture adjustment component 41 can drive the irrigation device on the clamping unit 30 to swing back and forth at a preset angle in the left and right directions, so that the irrigation device can realize the reciprocating switching of the angle of the irrigation device between the inclined state and the vertical state under the cooperation of the posture adjustment component 41 and the vibration component 42. Since the irrigation device swings left and right, the fluidity of the bubbles in the irrigation device can be increased, so that the bubbles can be separated and discharged from the irrigation device more quickly. Therefore, through the setting of the vibration component 42 and the posture adjustment component 41, it is not necessary to manually use a hammer to knock the irrigation device to remove bubbles. The vibration component 42 can realize automatic exhaust, and in the case of swinging left and right, the bubble removal effect is better, the bubble removal time in the irrigation device is shorter, and the removal effect is better, which reduces the workload of medical staff, and the bubble removal efficiency of the irrigation device is higher, and the irrigation work can be carried out faster, which improves the patient's treatment experience.

[0037] In some embodiments, the electronic cartridge exhaust device 100 further includes a bubble monitoring unit 50, which includes a bubble sensor 51 and a controller 52. The bubble sensor 51 and the vibration exhaust unit 40 are both electrically connected to the controller 52. The bubble sensor 51 is used to monitor the bubbles in the outlet pipeline of the cartridge. When the bubble sensor 51 detects that the bubbles in the outlet pipeline of the cartridge are less than a first threshold, the controller 52 controls the vibration exhaust unit 40 to stop working; when the bubble sensor 51 detects that the bubbles in the outlet pipeline of the cartridge are greater than a second threshold, the controller 52 controls the vibration exhaust unit 40 to work. Through the setting of the bubble monitoring unit 50, the bubble sensor 51 in the bubble monitoring unit 50 can monitor the bubbles in the outlet pipeline of the cartridge, which can play a role in monitoring the exhaust progress of the cartridge. When the number of bubbles in the cartridge is less than the first threshold, that is, when the bubbles in the cartridge are almost completely removed with the saline or the amount of bubbles is small, it means that the exhaust work of the cartridge is nearly completed, so the vibration exhaust unit 40 can be automatically controlled to stop working, which is convenient for further perfusion operation. When the bubble sensor 51 detects that the bubbles in the outlet pipeline of the cartridge are greater than the second threshold value, indicating that the amount of bubbles in the cartridge is large and / or the bubbles are large, the vibration exhaust unit 40 works or continues to work to exhaust the bubbles in the cartridge to the required level. Medical staff do not need to pay attention all the time, which reduces the workload of medical staff and has a high degree of automation.

[0038] The first threshold and the second threshold of the bubble sensor 51 can be set according to actual conditions. The first threshold can be the amount of bubbles within a certain period of time. For example, the first threshold can be 2 bubbles within a 10-second time interval, or 1 bubble within a 10-second time interval. Then, when the number of bubbles in the outlet pipeline of the perfusion device is less than one or two within 10 seconds, it indicates that the bubble removal is basically completed. The second threshold can be equal to the first threshold, or it can be different from the first threshold. In this embodiment, the values ​​of the first threshold and the second threshold are equal.

[0039] Of course, the first threshold value may also be the size of the bubble within a certain period of time. For example, the first threshold value may be that the size of the bubble is less than 2 mm or 1 mm within a time interval of 10 seconds.

[0040] Alternatively, the first threshold may be that the number of bubbles is less than 1 and the size is less than 2 mm within a 10-second time interval. The second threshold is that the number of bubbles is greater than 1 and the size is greater than 2 mm within a 10-second time interval. The first threshold and the second threshold may be set according to actual conditions.

For example, after the vibration motor 421 on one side of the perfusion device vibrates for a few seconds, the multiple vibration motors 421 on the other side work, and the reciprocating operation is performed in sequence, so that the bubbles in the perfusion device are more easily discharged from the outlet pipe in a regular manner.

[0051] In addition, a visual window is provided on the fixed splint 31 and / or the movable splint 32, and the setting position of the visual window is staggered with the installation position of the vibration motor 421 on the fixed splint 31 and / or the movable splint 32, that is, the opening position of the visual window is staggered with the vibration component 42. Through the setting of the visual window, medical staff can observe the state in the perfusion device and whether blood coagulation occurs in the perfusion device. Of course, a transparent cover can be provided on the visual window, and the transparent cover plays a role of sealing the visual window.

[0052] In some embodiments, a blood monitoring unit is provided on the base 10, and the blood monitoring unit includes a first color sensor 60, a timer 63 and an alarm 62, and the first color sensor 60, the timer 63 and the alarm 62 are all electrically connected to the controller 52; the first color sensor 60 is provided on the base 10, and the first color sensor 60 is used to monitor the color of the liquid in the inlet pipeline of the perfusion device, and the timer 63 is used to start timing after the first color sensor 60 detects the blood flowing into the inlet pipeline, and the controller 52 controls the alarm 62 to send a first prompt signal after the timer 63 reaches the preset time, so as to prompt the end of the perfusion treatment. Through the setting of the first color sensor 60, the first color sensor 60 can identify and monitor the color of the liquid in the inlet pipeline of the perfusion device, and when the inlet pipeline enters the blood, it indicates that the perfusion starts, and the timer 63 can automatically record the time. After the timer 63 reaches the preset time, it indicates that the perfusion time reaches the preset duration, and the alarm 62 can send a first prompt signal to prompt the medical staff that the perfusion is over and to proceed to the next step, so that the medical staff does not need to pay attention to the progress of the perfusion at all times, and the automation level is higher.

[0053] The color sensor is also called a color recognition sensor or a color sensor. It is a sensor that detects the color by comparing the color of an object with a previously taught reference color. When the two colors match within a certain error range, the detection result is output. In this embodiment, when the color of the liquid at the inlet turns into the color of blood, it indicates that perfusion has started.

[0054] The preset duration of the timer 63 can be set according to actual conditions. For example, the preset duration can be 2 hours. The alarm 62 can be a buzzer or a loudspeaker, and the first prompt signal can be a prompt signal such as beep, clack or beep.

[0055] In some embodiments, the blood monitoring unit further includes a second color sensor 61, which is electrically connected to the controller 52. The second color sensor 61 is used to monitor the color of the liquid in the outlet pipeline of the cartridge and becomes lighter to a preset color. The controller 52 controls the alarm 62 to send a second prompt signal to indicate that the saline flushing is finished. Through the setting of the second color sensor 61, the second color cartridge can set a standard through the controller 52 to set an alarm to send a second prompt signal after the color of the liquid in the outlet pipeline of the cartridge becomes lighter to a preset color, such as when the color becomes lighter from red to a certain degree, indicating that the saline flushing of the cartridge is finished and the tank can be removed.

[0056] The second reminder signal can be a continuous sound, which is a stronger reminder. The second color sensor 61 can have the same structure as the first color sensor 60, but its setting position is different. The first color sensor 60 can be set at the inlet pipe position of the perfusion device, and the second color sensor 61 can be set at the outlet pipe position of the perfusion device.

[0057] In some embodiments, the mounting unit 20 includes a fixing plate 21 and a locking member 22. The fixing plate 21 is connected to the base 10. The fixing plate 21 has a U-shaped slot 23, which is used to be clamped on the column of the dialysis machine; the locking member 22 is threadedly matched with the fixing plate 21, and one end of the locking member 22 extends into the slot 23 to abut against the outer wall of the column. By adopting the fixing unit as the fixing plate 21 and the locking member 22, the slot 23 on the fixing plate 21 can be clamped on the column of the dialysis machine and tightened by the locking member 22. One end of the locking member 22 abuts against the outer wall of the column, so that the electronic perfusion device exhaust device can be fixed on the column of the dialysis machine, and the installation is convenient and quick. When the electronic perfusion device exhaust device needs to be removed, it is only necessary to loosen the locking member 22, which is convenient to operate.

[0058] The locking member 22 may be a locking screw, and the number of the locking members 22 may be one or two. The specific number of the locking members 22 may be determined according to actual conditions.

[0059] In some embodiments, the blood monitoring unit further includes a flow sensor 74, which includes a first flow sensor 74 and a second flow sensor 74. The first flow sensor 74 can record the amount of saline entering the inlet pipe of the perfusion device, and the second flow sensor 74 can record the amount of saline in the outlet pipe of the perfusion device. According to the first flow sensor 74 and the second flow sensor 74, the flushing volume of the perfusion device can be calculated, so that medical staff can better grasp the actual flushing volume.

[0060] The flow sensor 74 may be a flow meter.

[0061] Among them, the blood monitoring unit can also include a flow rate sensor and a prompter. The flow rate sensor is arranged at the inlet pipeline and the outlet pipeline of the perfusion device. The flow rate sensor can monitor the fluid velocity in the inlet pipeline and the outlet pipeline of the perfusion device. By analyzing the fluid velocity and difference in the inlet pipeline and the outlet pipeline of the perfusion device, it can be determined whether blood coagulation occurs in the perfusion device. When the fluid velocity in the outlet pipeline of the perfusion device is lower than the threshold value, or the difference value of the fluid velocity between the inlet pipeline and the outlet pipeline exceeds the preset value, the prompter can send a prompt signal to prompt the medical staff that blood coagulation may occur in the perfusion device, so that the medical staff can take timely measures.

[0062] The base 10 is provided with a plurality of control buttons 72, which may include a switch button, an adjustment button, etc. The control buttons 72 may control the exhaust device of the electronic injector.

[0063] In addition, for the sensor in the present application document, in order to facilitate the sensor to monitor the bubbles, color, flow rate and flow rate of the inlet and outlet pipelines of the perfusion device, a winding post 70 is provided on the base 10, and the wire 73 of the corresponding sensor is wound on the winding post 70, one end of the wire 73 is electrically connected to the controller 52 in the base 10, and the other end of the wire 73 is provided with a tube clamp 71, and the corresponding sensor is installed and fixed on one side of the opening of the tube clamp 71. When the perfusion device is positioned and installed in the clamping unit 30, the wire 73 is wound on the winding post 70, the wire 73 is pulled out, and the corresponding tube clamp 71 is clamped on the corresponding pipeline of the perfusion device, and the corresponding sensor can realize the non-contact monitoring of the liquid color or the amount of bubbles in the liquid with the pipeline of the perfusion device. In addition to the tilt sensor 415, such as the first color sensor 60, the second color sensor 61, the bubble sensor 51, the flow sensor 74 and the flow rate sensor, can all be applied. The tube clamp 71 can be a commonly used medical tube clamp, etc., which is convenient to purchase.
