Referring to fig. 4, in some embodiments, the control valve 200a is movably connected to the infusion tube 100, and the control valve 200a at least partially extends from the infusion tube 100 into the delivery channel 110 and defines a first adjusting channel 212 with an inner wall of the delivery channel 110, and the driving unit 300 can drive the control valve 200a to movably adjust a flux of the first adjusting channel 212 with respect to the infusion tube 100 so as to adjust a flow rate of the liquid delivered along the delivery channel 110.
It should be noted that the flux of the first adjustment channel 212 itself refers to the volume of the perfusion fluid transported along the first adjustment channel 212 to the perfusion fluid inlet per unit time. The larger the flux, the smaller the portion of the control valve 200a extending into the perfusion tube 100, the larger the volume of the perfusion fluid delivered to the perfusion fluid inlet along the first adjustment channel 212 per unit time, and conversely, the smaller the flux, the larger the portion of the control valve 200a extending into the perfusion tube 100, the smaller the volume of the perfusion fluid delivered to the perfusion fluid inlet along the first adjustment channel 212 per unit time.
Referring to fig. 4, in one embodiment, the control valve 200a includes a valve core 210, a circumferential wall of the perfusion tube 100 is provided with a first installation hole, the valve core 210 extends into the conveying channel 110 through the first installation hole and defines a first adjustment channel 212 with an inner wall of the conveying channel 110, and the valve core 210 is connected to the driving unit 300 to move relative to the perfusion tube 100 under the driving of the driving unit 300.
Referring to fig. 4, a first adjusting channel 212 is defined between an end portion of the valve core 210 extending into the infusion tube 100 and an inner wall of the infusion tube 100 facing the end portion of the valve core 210, and when the driving unit 300 drives the valve core 210 to move relatively in a direction approaching or departing from the inner wall, the flux of the first adjusting channel 212 can be changed.
The valve core 210 can move directly or rotate and move relative to the infusion tube 100. In other words, the driving unit 300 may be a linear driving mechanism or the driving unit 300 and the valve body 210 constitute a screw nut-like structure.
For example, referring to fig. 4, in some embodiments, the driving unit 300 includes a transmission shaft 310, a motor 320 and a speed reducing mechanism (not shown), the transmission shaft 310 is provided with a first thread structure, the valve core 210 is provided with a second thread structure, the first thread structure and the second thread structure are in screw fit, an output shaft of the motor 320 is connected with the transmission shaft 310 through the speed reducing mechanism to drive the valve core 210 to move relative to the infusion tube 100 when the output shaft of the motor 320 rotates, and the motor 320 is in communication connection with the control device.
A screw nut-like structure is formed between the transmission shaft 310 and the valve core 210, and when one of them rotates, the other moves forward while rotating. Specifically, the first thread structure may be an internal thread structure, and the second thread structure may be an external thread structure; alternatively, the first thread formation may be an external thread formation, and the second thread formation may be an internal thread formation, as opposed to an external thread formation.
With reference to fig. 4, in addition to the above-mentioned embodiment, the pouring tube 100 is further provided with a bypass channel 400, and both the liquid inlet of the bypass channel 400 and the liquid outlet of the bypass channel 400 are communicated with the conveying channel 110, in the liquid conveying direction along the conveying channel 110, as shown in the direction L in fig. 4. The first adjustment passage 212 is disposed between the inlet of the bypass passage 400 and the outlet of the bypass passage 400. Infusion assembly 10a further includes a manual bypass valve 500, and manual bypass valve 500 is connected to infusion tube 100 for controlling the opening and closing of bypass channel 400.
When the control valve 200a fails to deliver the perfusion fluid into the body cavity through the control valve 200a, the manual dredging valve 500 is opened to conduct the bypass channel 400, so that the perfusion fluid can be delivered into the body cavity along the bypass channel 400. When the control valve 200a is in the normal operation state, the manual dredging valve 500 is in the state of closing the bypass channel 400, and the perfusion fluid is still delivered into the body cavity through the control valve 200 a.
The manual dredging valve 500 may be any valve body in the prior art that can control the pipeline switch, for example, the manual dredging valve 500 may be a stop valve.
Referring to fig. 5 to 7, in other embodiments, the conveying channel 110 includes a first section of channel 112 and a second section of channel 114 arranged along the liquid conveying direction L of the conveying channel 110, the control valve 200a is opened with a second adjusting channel 220, and the first section of channel 112 is communicated with the second section of channel 114 through the second adjusting channel 220.
In some embodiments, the drive unit 300 can drive the control valve 200a to adjust the flux between the second adjustment passage 220 and the first-stage passage 112 and/or the second-stage passage 114 to adjust the flow rate of the liquid delivered along the first-stage passage 112 to the second-stage passage 114. Because the second adjustment channel 220 is disposed between the first section channel 112 and the second section channel 114, the perfusate conveyed from the first section channel 112 to the second section channel 114 needs to pass through the second adjustment channel 220, when the flux between the first section channel 112 and the second adjustment channel 220 is changed, the flux between the second section channel 114 and the second adjustment channel 220 is not changed, or the flux between the first section channel 112 and the second adjustment channel 220 is not changed, and the change in the flux between the second adjustment channel 220 and the second section channel 114 affects the flow rate of the perfusate conveyed into the body cavity along the second section channel 114.
Specifically, the flux between the first-stage passage 112 and the second tuning passage 220 can be varied by controlling the flux at the connection of the first-stage passage 112 and the second tuning passage 220 by the control valve 200a, for example, by an external member pressing the connection to deform it. Similarly, the flux between the second segment channel 114 and the second tuning channel 220 can be varied by controlling the flux at the junction of the second segment channel 114 and the second tuning channel 220 by the control valve 200a, for example by an external element pressing the junction to deform it to effect the varying flux.
Alternatively, in some other embodiments, the driving unit 300 can drive the control valve 200a to adjust the flux of the second adjustment passage 220 itself to adjust the flow rate of the liquid delivered to the second-stage passage 114 along the first-stage passage 112. The flux of the second regulation passage 220 itself may be adjusted by compressing the control valve 200a by an external member, thereby deforming the second regulation passage 220 and thus realizing the regulation of the flux of the second regulation passage 220.
Referring to fig. 5 and 6, for example, in some embodiments, the control valve 200a includes an elastic member 230, the elastic member 230 is formed with a second adjustment passage 220, and the driving unit 300 is configured to apply a force to the elastic member 230, so that the elastic member 230 is deformed to adjust the flux of the second adjustment passage 220 itself.
