[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-8 As shown, a combined wound cleaning and nursing device for operating rooms includes a transparent cover 1, characterized in that it includes a suction head 7 disposed at the end of the transparent cover 1;

[0036] Rinse pipes 6 are positioned opposite each other on both sides of the suction head 7;

[0037] Pressing block 3 for pushing the suction head 7;

[0038] The locking member 21, which is fixedly installed inside the transparent cover 1, has a high groove 25 and a low groove 26 that are arranged opposite to each other and used to limit the extension length of the suction head 7.

[0039] The plug 72 located at the end of the suction head 7 forms a suction channel through the gap between it and the suction head 7.

[0040] Among them, the suction head 7 makes the suction flow rate adjustable during the high and low position switching process.

[0041] Specifically, it also includes ultrasonic generators 2 set on both sides of the transparent cover 1, which supply saline to the flushing tube 6 through the fixedly set liquid outlet tube 24. The ultrasonic generators 2 are used to generate cavitation phenomenon in the saline in the flushing tube 6. The transparent cover 1 is connected to a suction tube 5, which is connected to a negative pressure suction machine. The above technology is common knowledge to those skilled in the art and will not be described in detail here.

[0042] Furthermore, the operator can hold the transparent cover 1 with one hand and adjust the pressing block 3 with their fingers. The pressing block 3 is movably inserted into the transparent cover 1, and the end of the pressing block 3 is rotatably connected to the suction head 7. First, slide the pressing block 3 until it is misaligned with the locking member 21, and then slide it along the high position groove 25, as shown. Figure 4 As shown, during the sliding process, the distance between the suction head 7 and the plug 72 gradually shortens, narrowing the suction channel and reducing the flow rate. When the suction head 7 reaches the limit position of the high-level groove 25, the suction channel is completely blocked. At this time, the device only achieves the flushing effect through the flushing pipe 6. When readjustment is required, the pressing block 3 is displaced from the locking member 21, and the pressing block 3 is rotated to correspond with the low-level groove 26. It is then slid along the low-level groove 26 to the limit position. At this position, the suction head 7 and the plug 72 maintain a predetermined distance, ensuring that the suction channel is unobstructed and the flushing pipe 6 continues to flush. Afterward, the finger can be released, eliminating the need for continuous adjustment of the pressing block 3 and reducing the burden on the operator. Since the ultrasonic generator 2 is located on the side of the transparent cover 1, ultrasonic waves are transmitted to the inside of the transparent cover 1 through mechanical energy, oscillating the suctioned waste liquid and preventing blockage of the suction head 7. The state of the waste liquid can also be checked in a timely manner by observing the transparent cover 1.

[0043] In the above technology, the operator can hold the transparent cover 1 with one hand and adjust the pressing block 3 with their fingers to adjust the width of the suction channel, thereby changing the suction flow rate. The flow rate can be adjusted in a timely manner according to the amount of exudate, plasma, pus, etc. on site. The flushing and suction actions can be completed with one hand. Combined with the cavitation effect of the ultrasonic generator 2, the damaged surface is cleaned and the suctioned waste liquid is oscillated.

[0044] As a further embodiment of the present invention, the plug 72 is rotatably disposed relative to the suction head 7, and the plug 72 has a frustum-shaped structure that increases in size along the liquid inlet direction.

[0045] Specifically, such as Figure 2 As shown, multiple scrapers are arranged in a circumferential array on the stopper block 72. During the liquid inlet process, the waste liquid is drawn into the suction head 7 along the side of the stopper block 72 by the suction force. The force of the waste liquid on the scrapers drives the stopper block 72 to rotate, thereby generating eddies when the waste liquid flows, further separating solids such as tissues and debris in the waste liquid. The rotation of the scrapers scrapes the suction head 7, reducing blockage.

[0046] As a further embodiment of the present invention, it also includes a pressure rod 22 that is slidably disposed inside the transparent cover 1 and rotatably disposed relative to the suction head 7, and a guide block 31 for guiding the deflection of the pressure rod 22 is provided on the pressing block 3.

[0047] Specifically, the pressing block 3 is coaxially sleeved within the locking member 21, and the pressing rod 22 has multiple inclined rods arranged in a circumferential array to engage with the guide block 31. In the default state, the inclined rods are located in the high slot 25. At this time, the plug 72 blocks the suction head 7. Then, the pressing block 3 is pressed down, which causes the guide block 31 to squeeze the inclined rods. The inclined rods are tangential to the toothed surface of the guide block 31 and are deflected by the guide, causing the pressing rod 22 to deflect as a whole. Then the pressing block 3 moves up, and the deflected pressing rod 22 corresponds to the low slot 26. The pressing rod 22 slides along the low slot 26 to the limit position of the low slot 26. At this time, a certain distance is maintained between the plug 72 and the suction head 7, so that the suction channel is stable and unobstructed and the operator does not need to continue to press down the pressing block 3.

[0048] As a further embodiment of the present invention, it also includes a rotating member 61 rotatably disposed at the end of the flushing pipe 6 and unidirectionally rotating with the suction head 7, and a lever 62 is provided on the flushing pipe 6 to block the rotating member 61.

[0049] Specifically, such as Figure 8 As shown, a locking tooth 66 is rotatably mounted on the rotating component 61, and multiple serrations 74 are arranged in a linear array on the suction head 7. When the suction head 7 extends away from the transparent cover 1, the serrations 74 drive the locking tooth 66 to rotate relative to the rotating component 61. The lever 62 engages with the locking tooth 66, providing damping and allowing the suction head 7 to stop at different extension lengths. Since the rotating component 61 is an eccentric wheel, it adaptively deflects according to the different positions of the suction head 7 and the rotating component 61, thereby maintaining a distance between the end of the flushing tube 6 and the suction head 7, preventing the suction head 7 from directly sucking the liquid out of the flushing tube 6 port. When the suction head 7 retracts, the serrations 74 no longer guide the locking tooth 66 to rotate, reducing the obstruction when the suction head 7 retracts.

[0050] As a further embodiment of the present invention, the suction head 7 is provided with a stop 71 at its end, and the flushing pipe 6 is provided with a liquid outlet channel 63, and there is a station for blocking the liquid outlet channel 63 in the moving stroke of the rotating member 61.

[0051] Specifically, a ball bearing 65 is installed inside the liquid outlet channel 63, and a spring is installed on the ball bearing 65 to keep it offset from the liquid outlet channel 63. A transmission component 64 is also rotatably installed on the flushing pipe 6 and is rotatably connected to the lever 62. When the suction head 7 retracts, it gradually drives the stop block 71 to abut against the rotating component 61, causing the rotating component 61 to deflect and squeeze the lever 62. The lever 62 will support the transmission component 64 and push the ball bearing 65 into the liquid outlet channel 63. At this time, the flushing pipe 6 no longer discharges liquid, and the device only has a suction function.

[0052] As another embodiment of the present invention, the suction head 7 is provided with a converging port 73 whose inner diameter decreases along the liquid inlet direction.

[0053] Specifically, the operator slides the pressing block 3 until it is misaligned with the locking member 21. At this time, the inclined rod is misaligned with the locking member 21, and the suction head 7 extends the longest distance. At this time, the plug 72 and the converging port 73 are located under the same cross section. The channel formed between the converging port 73 and the plug 72 is relatively narrow, which makes the waste liquid accelerate when passing through the channel and form a negative pressure environment due to the speed difference, thereby strengthening the suction force of the suction head 7. In addition, when the waste liquid accelerates, it drives the plug 72 to rotate rapidly. The rotation of the plug 72 breaks up the tissue debris in the waste liquid and reduces agglomeration.

[0054] As a further embodiment of the present invention, it also includes an elastic rib 8 disposed within the pressure rod 22 and used to maintain a predetermined distance between the pressure rod 22 and the guide block 31.

[0055] Specifically, the spring rib 8 is used to push the pressure rod 22, causing the suction head 7 to maintain its tendency to retract into the transparent cover 1. In the default state, the inclined rod is located in the high position groove 25. At this time, the plug block 72 blocks the suction head 7. Then, the pressing block 3 is pressed down, the elastic rib 8 contracts and stores force, the guide block 31 squeezes the inclined rod, and the inclined rod is deflected by the guide sliding when it is tangential to the toothed surface of the guide block 31, so that the pressure rod 22 is deflected as a whole and corresponds to the low position groove 26. At this time, the pressure is released, the stored force of the elastic rib 8 is released and pushes the pressure rod 22, so that the inclined rod automatically inserts into the low position groove 26, completing the high and low position switching.

[0056] As another embodiment of the present invention, the elastic rib 8 is provided with a plurality of separation fins 81 arranged in a spiral array facing the suction head 7; the elastic rib 8 is deflected and twisted by the pressure rod 22.

[0057] Specifically, the two ends of the elastic rib 8 are fixedly connected to the pressure rod 22 and the guide block 31, respectively. When the pressure rod 22 deflects, the guide block 31 is provided with a slider 32 that cooperates with the keyway of the locking member 21, causing the guide block 31 to deflect relative to the pressure rod 22. The elastic rib 8 twists into a spiral shape, causing the separation fins 81 to form a spiral array. Furthermore, due to the twisting of the elastic rib 8 itself, the tail of the separation fins 81 unfolds along the tangential direction of the twist, cutting and breaking up the tissue debris in the liquid.

[0058] As another embodiment of the present invention, it also includes a suction head 42 coaxially arranged with the elastic rib 8 and used for suctioning solids.

[0059] Specifically, it also includes a separation tube 41 connected to the suction head 42, and the separation tube 41 is connected to a waste bag 4. Because the elastic rib 8 is twisted into a spiral shape, combined with the scraper on the stopper 72, the waste liquid forms a vortex during the suction process. Under the action of the vortex, the flow velocity at the center will be relatively high, and due to the centrifugal force, larger tissue fragments will be thrown to the periphery near the elastic rib 8, and then cut up by the separation fin 81. The suction head 42 is equipped with a one-way membrane, and the liquid is drawn into the waste bag 4 through the adsorption of the suction head 42, while the remaining cut tissue fragments will be drawn up by the suction tube 5, separating the solid and liquid of the waste liquid, which is beneficial for subsequent testing and processing steps.

[0060] As another embodiment of the present invention, the locking member 21 is provided with an annular groove 28 for the pressure rod 22 to be misaligned with the locking member 21.

[0061] Specifically, the guide block 31 is rotatably mounted on the pressing block 3, and also includes a groove 27 formed on the locking member 21 for the sliding of the slider 32. When the operator slightly presses down the pressing block 3, the slider 32 only slides within the groove 27. In the default state, the inclined rod is located in the high position groove 25. At this time, the plug 72 blocks the suction head 7, and the stop block 71 drives the rotating member 61 to deflect, thus blocking the liquid outlet channel 63 of the flushing pipe 6.

[0062] Then, the pressing block 3 is pressed down, the elastic rib 8 contracts and stores force, the guide block 31 squeezes the inclined rod, the inclined rod is tangential to the toothed surface of the guide block 31 and is deflected by the guide, so that the pressure rod 22 is deflected as a whole and corresponds to the low position groove 26. At this time, the hand is released, the stored force of the elastic rib 8 is released and pushes the pressure rod 22, so that the inclined rod is automatically inserted into the low position groove 26. The plug block 72 and the suction head 7 maintain a predetermined distance, and the end of the flushing pipe 6 maintains a distance from the suction head 7 to avoid the suction head 7 directly sucking the liquid out of the port of the flushing pipe 6. The device simultaneously sucks and flushes.

[0063] When the pressing block 3 is pressed down further, the slider 32 enters the annular groove 28, and the extension distance of the suction head 7 is the longest. At this time, the plug 72 and the converging port 73 are located under the same cross section. The channel formed between the converging port 73 and the plug 72 is relatively narrow, which makes the waste liquid accelerate when passing through the channel, and a negative pressure environment is formed due to the speed difference, which strengthens the suction force of the suction head 7. At this time, the guide block 31 can rotate freely, the elastic rib 8 releases its elasticity, no longer twists, and returns to the default state.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
