Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a medical flushing and suction device. Background Technology

[0002] The medical flushing and suction device can be connected to a water source for water spraying and can also be connected to an air source for liquid suction. Chinese utility model patent CN 221154876 U discloses a medical flushing and suction device with easily adjustable flow rate. It includes a handle, a flushing head, and a tube connecting the handle and the flushing head. The tube includes an inner tube for flushing and an outer tube for suction. The handle contains a rubber hose connected to either the inner or outer tube. The handle also contains a flushing connector and a suction connector connected to the inner and outer tubes. The handle has two adjusting devices for regulating the flow rate and on / off state of the flushing and suction connectors, with the two adjusting devices located on opposite sides of the handle.

[0003] However, since the two adjustment devices are located on opposite sides of the handle, it is not easy to adjust the adjustment device located near the back of the hand with one hand to control the flow of gas or liquid in the corresponding tube. Usually, the other hand is required to adjust it. However, in actual operation, medical staff sometimes hold other surgical instruments or supplies in their other hand, which makes it inconvenient to adjust the medical flushing and aspiration device. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model provides a medical irrigation and aspiration device, comprising a handheld shell and a lever adjustment structure. The handheld shell contains a first fluid medium tube and a second fluid medium tube. Two lever adjustment structures are arranged adjacent to each other or spaced apart. Both lever adjustment structures are located on the same side of the handheld shell and are rotatably connected to the handheld shell. The two lever adjustment structures cooperate with the first fluid medium tube and the second fluid medium tube respectively to adjust the corresponding flow rate or on / off state.

[0005] Optionally, the handheld shell is provided with a gripping part, and both of the lever adjustment structures are located above or to the side of the gripping part.

[0006] Optionally, the handheld housing is detachably connected to a rinsing head.

[0007] Optionally, the front end of the handheld shell is connected to a manifold, and the manifold is provided with a first channel and a second channel at intervals on the side of the manifold close to the lever adjustment structure. The side of the manifold away from the lever adjustment structure is provided with a manifold port. The first channel and the second channel are both connected to the manifold port. The first fluid medium tube is connected to the first channel, and the second fluid medium tube is connected to the second channel.

[0008] Optionally, the outer wall of the handheld shell is provided with an adjustment port, and a mounting block is provided at the adjustment port. The mounting block is located inside the handheld shell. Both side walls of the mounting block are provided with rotation grooves. The two lever adjustment structures are respectively inserted into the corresponding rotation grooves and rotatably connected to the mounting block. One end of each of the two lever adjustment structures protrudes from the adjustment port and is in a cantilevered state.

[0009] Optionally, the first fluid medium tube and the second fluid medium tube pass through the two rotating slots respectively, and the corresponding lever adjustment structure is adapted to squeeze the first fluid medium tube or the second fluid medium tube after rotating relative to the handheld shell. Both the first fluid medium tube and the second fluid medium tube are flexible tubes that can deform under the squeezing force.

[0010] Optionally, the lever adjustment structure is provided with a gear position protrusion, and the mounting block and / or the handheld housing is provided with a gear position slot. Multiple gear position slots are spaced apart circumferentially. After the lever adjustment structure rotates relative to the handheld housing, the gear position protrusion is adapted to engage with any one of the gear position slots.

[0011] Optionally, the lever adjustment structure includes a rotating column, an adjustment lever, and an eccentric protrusion. The adjustment lever and the eccentric protrusion are both located on the outer wall of the rotating column and are arranged at intervals. The adjustment lever and the eccentric protrusion are both fixedly connected to the rotating column. The adjustment lever is adapted to protrude from the adjustment port in a cantilevered state. After rotation, the eccentric protrusion is adapted to squeeze the first fluid medium tube or the second fluid medium tube.

[0012] Optionally, two toggle limiting plates are fixed and symmetrically arranged in the rotating groove, and the adjusting lever rotates and adjusts between the two toggle limiting plates.

[0013] Optionally, the rotating groove has a limiting slot on its wall. When the eccentric protrusion is not in contact with the first fluid medium pipe or the second fluid medium pipe, the eccentric protrusion is engaged in the limiting slot, and the adjusting lever abuts against the corresponding toggle limiting plate.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] 1. The two lever adjustment structures for controlling the flow rate and on / off state of the first and second fluid medium pipes are located on the same side of the handheld housing, which makes it convenient for the user to operate the two lever adjustment structures with one hand, thus improving the convenience of operating the medical flushing and aspiration device.

[0016] 2. Since the lever adjustment structure is located above the grip, and the lever adjustment structure is an eccentric lever structure, when adjusting, the operator only needs to use his thumb to push the corresponding lever adjustment structure to squeeze the first fluid medium tube or the second fluid medium tube to adjust the flow rate, which not only ensures the stability when gripping, but also improves the convenience of adjustment operation.

[0017] 3. The rinsing head and handheld housing are detachably connected, allowing for the replacement of the appropriate rinsing head for different usage scenarios, thus broadening the range of applications;

[0018] 4. The gear position protrusion and gear position slot work together to ensure that the lever adjustment structure can stably maintain the corresponding state after each adjustment, without requiring the operator to constantly apply force to the lever adjustment structure.

[0019] 5. The two toggle limit plates can limit the rotation range of the lever adjustment structure, so that when the lever adjustment structure is within the two extreme range values, the eccentric protrusion can stably maintain the corresponding state and is not prone to overfitting.

[0020] 6. When the eccentric protrusion does not play a role in squeezing and adjusting, the eccentric protrusion is engaged in the limiting groove to achieve a locking and limiting effect, so that the entire lever adjustment structure is not prone to free rotation and contact with the first fluid medium pipe or the second fluid medium pipe due to gravity or vibration, thus affecting the flow rate.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be described in further detail.

[0028] This utility model provides a medical flushing and suction device, see reference. Figure 1 and Figure 2 The medical irrigation and aspiration device includes a handheld housing 1 and a lever adjustment structure 2. The handheld housing 1 contains a first fluid medium tube and a second fluid medium tube, both of which are flexible tubes capable of deformation under pressure. Two lever adjustment structures 2 are provided, both located on the same side of the handheld housing 1 and rotatably connected to it. Each lever adjustment structure 2 engages with the first and second fluid medium tubes respectively. Rotation of the lever adjustment structure 2 relative to the handheld housing 1 will compress the corresponding first or second fluid medium tube, thereby adjusting the flow rate or switching it on / off.

[0029] The handheld housing 1 includes a first half-shell and a second half-shell, which facilitates the assembly of the first fluid medium pipe, the second fluid medium pipe, the lever adjustment structure 2, and other components. After the first half-shell and the second half-shell are fastened together, they will be fixed together by ultrasonic welding technology, thereby improving the stability and sealing of the connection between the first half-shell and the second half-shell.

[0030] Reference Figure 1 and Figure 2 The handheld housing 1 has a first hose connector 11 and a second hose connector 12 installed at intervals inside, with one end of each connector protruding from the handheld housing 1. One end of a first fluid medium tube is connected to and communicates with the first hose connector 11; one end of a second fluid medium tube is connected to and communicates with the second hose connector 12. The end of the first hose connector 11 located outside the handheld housing 1 is connected to a liquid source via a pipe to allow liquid to flow into the first fluid medium tube for rinsing. The end of the second hose connector 12 located outside the handheld housing 1 is connected to a suction device via a pipe to achieve a suction function, and the suctioned fluid medium is discharged from the handheld housing 1 through the second fluid medium tube. In another embodiment, the end of the first hose connector 11 located outside the handheld housing 1 can be connected to a suction device via a pipe; conversely, the end of the second hose connector 12 located outside the handheld housing 1 is connected to a liquid source via a pipe.

[0031] Reference Figure 2 and Figure 3The handheld housing 1 has a manifold 13 at its front end, with one end protruding from the handheld housing 1 and the other end inserted and fixed inside the handheld housing 1. The manifold 13, inserted inside the handheld housing 1, has a first channel 131 and a second channel 132 spaced apart on the side near the lever adjustment structure 2. A first fluid medium tube is connected to the manifold 13 and communicates with the first channel 131; a second fluid medium tube is connected to the manifold 13 and communicates with the second channel 132. The end of the manifold 13 protruding from the handheld housing 1 has a manifold port 133, with both the first channel 131 and the second channel 132 communicating with the manifold port 133. During rinsing, liquid in the first fluid medium tube will be ejected through the manifold port 133; during suction, external fluid medium will enter the second fluid medium tube through the manifold port 133.

[0032] The outer wall of the manifold 13 with the manifold port 133 has an external thread, and a flushing head 14 is sleeved and threadedly connected to the end of the manifold 13 with the manifold port 133, and the flushing head 14 communicates with the manifold port 133. Users can replace the corresponding flushing head 14 for different usage scenarios. In another embodiment, the flushing head 14 can also be snapped into the manifold 13 via a snap-fit ​​structure. In yet another embodiment, the flushing head 14 can be threaded to the front end of the handheld housing 1 and communicate with the manifold port 133.

[0033] Reference Figure 2 and Figure 4 The handheld casing 1 is equipped with a grip portion 15, which can be held by one hand during use. Both lever adjustment structures 2 are located above the grip portion 15, and when the user holds the grip portion 15, the two lever adjustment structures 2 are positioned at the web of the user's hand. Thus, during adjustment, the user only needs to push the corresponding lever adjustment structure 2 with their thumb to compress the first or second fluid medium tube to adjust the flow rate or shut it off, improving the convenience of adjustment operation.

[0034] In another embodiment, both lever adjustment structures 2 can be located on the side of the handheld shell 1, and when the user holds the handheld shell 1, both lever adjustment structures 2 are located on the side of the handheld shell 1 away from the back of the user's hand, so as to facilitate the thumb of the user's hand to adjust the lever adjustment structure 2.

[0035] The two lever adjustment structures 2 are spaced apart along the left and right direction of the handheld housing 1, so that when one lever adjustment structure 2 is pushed for adjustment, the other lever adjustment structure 2 is less likely to be accidentally touched. In another embodiment, the two lever adjustment structures 2 are arranged adjacent to each other.

[0036] Reference Figure 2 and Figure 4An adjustment port is provided above the grip portion 15 of the handheld housing 1, and the adjustment port communicates with the interior of the handheld housing 1. A mounting block 16 is provided at the adjustment port and is located inside the handheld housing 1. One side of each of the two lever adjustment structures 2 is rotatably connected to the two sides of the mounting block 16, and the other end of each lever adjustment structure 2 protrudes from the adjustment port in a cantilevered state after passing through the adjustment port, so as to facilitate user operation.

[0037] In detail, the two lever adjustment structures 2 are identical in structure. The lever adjustment structure 2 includes a rotating column 21, an adjustment lever 22, and an eccentric protrusion 23. The adjustment lever 22 and the eccentric protrusion 23 are both located on the outer wall of the rotating column 21 and are arranged at intervals. The adjustment lever 22 and the eccentric protrusion 23 are integrally formed with the rotating column 21. The adjustment lever 22 is adapted to protrude from the adjustment port in a cantilevered state, and the eccentric protrusion 23 is adapted to compress the corresponding first fluid medium tube or second fluid medium tube after rotation.

[0038] Reference Figure 4 and Figure 5 The mounting block 16 has rotating grooves 161 on both side walls. The rotating columns 21 on the two lever adjustment structures 2 are rotatably mounted on the bottom of the rotating grooves 161. The sides of the two rotating columns 21 that are away from each other are rotatably connected to the handheld housing 1. The sides of the two rotating grooves 161 closest to the adjustment port penetrate the mounting block 16, thus facilitating the protrusion of the adjustment lever 22 from the adjustment port. The mounting block 16 is fitted onto the first fluid medium pipe and the second fluid medium pipe, which pass through the two rotating grooves 161 respectively. The first and second fluid medium pipes are located on the side of the corresponding rotating column 21 away from the adjustment port, and both are in contact with the groove wall of the corresponding rotating groove 161 on the side away from the adjustment port. When one of the adjustment levers is pushed, causing the corresponding lever adjustment structure 2 to rotate relative to the handheld housing 1, the eccentric protrusion 23 presses against the corresponding first or second fluid medium pipe to achieve flow regulation or on / off switching.

[0039] The adjusting lever 22 has integrally formed position protrusions 24 on both the side near the bottom of the rotating groove 161 and the side near the inside of the handheld housing 1. Multiple position slots 17 are formed on the bottom of the rotating groove 161 and the inner wall of the corresponding side of the handheld housing 1, and these slots are arranged at intervals along the circumference of the rotating column 21. After the lever adjusting structure 2 rotates relative to the handheld housing 1, the position protrusions 24 are adapted to engage with any one of the position slots 17, ensuring that the lever adjusting structure 2 can stably maintain the corresponding state after each adjustment, without requiring the operator to continuously apply force to the lever adjusting structure 2. In another embodiment, the adjusting lever 22 has a position protrusion 24 only on the side near the bottom of the rotating groove 161, and correspondingly, only the bottom of the rotating groove 161 has a position slot 17. In yet another embodiment, the adjusting lever 22 has a position protrusion 24 only on the side near the corresponding side of the inner wall of the handheld housing 1, and correspondingly, only the inner wall of the corresponding side of the handheld housing 1 has a position protrusion 24.

[0040] Each of the two rotating grooves 161 has an integrally formed set of limiting plates, which are integrally formed on the bottom of the rotating groove 161. The following description takes the limiting plate set that cooperates with the first fluid medium pipe and the toggle adjustment structure as examples.

[0041] Reference Figure 4 and Figure 5 The limiting plate assembly includes two symmetrically arranged and spaced-apart toggle limiting plates 162. The adjusting lever 22 rotates between the two toggle limiting plates 162 for adjustment, thereby limiting the rotation range of the adjusting lever 22 and preventing over-fitting. The toggle limiting plates 162 are inclined, allowing the adjusting lever 22 to engage with the corresponding toggle limiting plate 162 at its two extreme points, increasing the contact area between the adjusting lever 22 and the corresponding toggle limiting plate 162 and improving stability.

[0042] When the adjustment lever 22 comes into contact with any of the toggle limit plates 162, the gear position protrusion 24 will engage with the corresponding gear position slot 17.

[0043] A limiting groove 163 is formed on the side of the rotating groove 161 away from the gripping part 15. When the eccentric protrusion 23 is not in contact with the first fluid medium pipe and the adjusting lever 22 is in contact with the corresponding actuating limiting plate 162, the eccentric protrusion 23 is engaged in the limiting groove 163. This makes the entire lever adjusting structure 2 less likely to rotate freely and come into contact with the first or second fluid medium pipe due to gravity or vibration, thus affecting the flow rate.

[0044] The implementation principle of a medical irrigation and suction device according to an embodiment of this application is as follows: Since the lever adjustment structure 2 is located above the grip 15 and the lever adjustment structure 2 is an eccentric lever structure, during adjustment, the operator only needs to push the corresponding lever adjustment structure 2 with their thumb to squeeze the first fluid medium tube or the second fluid medium tube to adjust the flow rate. In addition, during the adjustment process, the position protrusion 24 cooperates with the position slot 17, so that the lever adjustment structure 2 can stably maintain the corresponding state after each adjustment, without the operator needing to continuously apply force to the lever adjustment structure 2. When the eccentric protrusion 23 does not play a squeezing adjustment role, the eccentric protrusion 23 is engaged in the limiting slot 163 to achieve a locking limit, making the entire lever adjustment structure 2 less likely to rotate freely and come into contact with the first fluid medium tube or the second fluid medium tube due to gravity or vibration.
