[0033] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0034] Embodiment 1

[0035] like Figures 1 to 8 As shown, it is the first embodiment of the present invention, which provides a portable chest closed drainage monitoring device, including a body 10, on which a drainage box 11 is detachably mounted; a switching mechanism 20, which is arranged on the drainage box 11, and the switching mechanism 20 includes a shell 21 fixedly mounted on the drainage box 11, and three drainage tubes 22 are fixedly mounted on one side of the shell 21, and the drainage tubes 22 are connected to the inside of the shell 21, and a discharge hole 211 is opened on the inner wall of the other side of the shell 21, and the discharge hole 211 is connected to the drainage box 11, and a switching cylinder 23 is rotatably mounted inside the shell 21, and seven groups of switching holes 24 are circumferentially arranged on the switching cylinder 23, and the drainage tube 22 and the seven groups of switching holes 24 are respectively combined into seven groups of connected states for switching the opening and closing of the drainage tube 22; a stirring mechanism 30, which is arranged in the shell 21, and the stirring mechanism 30 includes a stirring blade 31 rotatably mounted in the shell 21, and the stirring blade 31 is located on the inner side of the switching cylinder 23;

[0036] Among them, each group of switching holes 24 includes at least one through hole, and at most three through holes, and the through hole is adapted to a drainage tube 22. When the seven groups of switching holes 24 are respectively fitted with the drainage tube 22, the switching mechanism 20 is respectively in seven connected states, and the seven connected states correspond one to one with the seven groups of switching holes 24.

[0037] Here, the drainage tube 22 is made of a transparent material, and the transparent material makes it easier for medical personnel to roughly judge the flow rate of the body fluid through the drainage tube 22 .

[0038] Furthermore, the discharge hole 211 is connected to the drainage box 11 through a U-shaped pipe, and the U-shaped pipe runs through the interior of the body 10. The body fluid drained from the patient passes through the drainage tube 22, the switching cylinder 23, the discharge hole 211, the U-shaped pipe in turn and flows into the interior of the drainage box 11, wherein the body 10 is capable of monitoring the body fluid flowing through the U-shaped pipe and obtaining relevant information (such as drainage volume, drainage speed, etc.). Specifically, monitoring the body fluid flowing through the U-shaped pipe through the body 10 is an existing conventional technology, and its specific working principle will not be further elaborated here.

[0039] It should also be noted that a discharge chamber is provided on the side of the shell 21 away from the switching cylinder 23, and the discharge hole 211 is located on the inner wall of the discharge chamber close to the drainage box 11. The discharge chamber is connected to the inner side of the switching cylinder 23, and there is a gap between the top of the switching cylinder 23 and the top of the discharge chamber. The dimension of the gap in the vertical direction is larger than the height dimension of the switching cylinder 23, so that in the process of the drainage material moving from the inside of the switching cylinder 23 to the discharge chamber, the drainage material mainly moves into the discharge chamber through the gap, and the distance between two adjacent groups of switching holes 24 is smaller than the width dimension of the discharge chamber, so as to ensure that at least one group of switching holes 24 is compatible with the discharge chamber to ensure the flow rate of the body fluid.

[0040] When the present invention is in use, the three drainage tubes 22 share one drainage box 11, which improves the integration and portability of the device. Since only one drainage box 11 needs to be monitored, the convenience of device monitoring is improved. After the switching cylinder 23 is rotated, the three drainage tubes 22 are aligned with different switching holes 24 to switch the connection state formed by the combination of the drainage tubes 22 and the switching holes 24, which is convenient for switching the opening and closing of each of the three drainage tubes 22, and is convenient for drainage through any one or more of the three drainage tubes 22, which improves the convenience of drainage by multiple drainage tubes 22, and the drainage The substance enters the shell 21 through the drainage tube 22 and is discharged from the shell 21 through the discharge hole 211. The device has high portability and can close the drainage tube 22 separately according to the flow of body fluids in different parts when draining multiple cavities. At the same time, the stirring blade 31 rotates to stir the drainage substance entering the shell 21, and breaks up the blockage in the drainage substance, so as to reduce the blockage of closed chest drainage. The blockage is the substance that easily causes blockage during closed chest drainage. Common blockages are blood clots, pus and tissue fragments.

[0041] When all three drainage tubes 22 need to be closed, the switching cylinder 23 is rotated to align the drainage tubes 22 to the middle of two adjacent switching holes 24. At this time, the three drainage tubes 22 are blocked by the outer wall of the switching cylinder 23, thereby closing all three drainage tubes 22.

[0042] Here, in order to better describe the working process of the present device, the three drainage tubes 22 are recorded as pipeline I, pipeline II and pipeline III from the upper end to the lower end, and the multiple groups of switching holes 24 are recorded as group A holes, group B holes, ..., group F holes and group G holes in a clockwise direction. When the three drainage tubes 22 and the group A holes are in contact with each other, the switching mechanism 20 is in a first connected state; when the three drainage tubes 22 and the group B holes are in contact with each other, the switching mechanism 20 is in a second connected state, and so on, ..., when the three drainage tubes 22 and the group G holes are in contact with each other, the switching mechanism 20 is in a seventh connected state, wherein when the switching mechanism 20 is in the first connected state, the body fluid inside pipeline I can flow into the inside of the switching cylinder 23 ; When the switching mechanism 20 is in the second connection state, the body fluid inside the pipeline II can flow into the switching cylinder 23; when the switching mechanism 20 is in the third connection state, the body fluid inside the pipeline III can flow into the switching cylinder 23; when the switching mechanism 20 is in the fourth connection state, the body fluid inside the pipeline I and the pipeline III can flow into the switching cylinder 23; when the switching mechanism 20 is in the fifth connection state, the body fluid inside the pipeline II and the pipeline III can flow into the switching cylinder 23; when the switching mechanism 20 is in the sixth connection state, the body fluid inside the pipeline I and the pipeline III can flow into the switching cylinder 23; when the switching mechanism 20 is in the seventh connection state, the body fluid inside the pipeline I, the pipeline II and the pipeline III can flow into the switching cylinder 23;

[0043] In a specific embodiment, when it is necessary to drain three different parts of the patient's body, the three drainage tubes 22 are respectively inserted into the parts that need drainage, and the switching mechanism 20 is switched to the seventh connection state, so that the body fluids of the parts of the patient's body can flow into the interior of the drainage box 11 through the three drainage tubes 22 respectively. Since the material of the drainage tubes 22 is a transparent material, the drainage speed of the body fluids in the three parts can be observed through the drainage tubes 22. If the flow rate of the body fluid in the pipeline I decreases or stops, the switching mechanism 20 is changed from the seventh connection state to the fifth connection state (at this time, the body fluids in the pipelines II and III can flow into the drainage box 11). into the switching cylinder 23); if the flow rate of the body fluid in pipeline I and pipeline II decreases or stops, the switching mechanism 20 is changed from the fifth connection state to the third connection state (at this time, the body fluid in pipeline III can flow into the switching cylinder 23), until the body fluids in three parts of the patient are drained. Through the above-mentioned arrangement, the device can drain the body fluids in multiple parts of the patient's body at the same time, and the device can open or close the flow states of the three drainage tubes 22 respectively according to the drainage conditions of different parts by changing the state of the switching mechanism 20, so that the device can be better suitable for patients with multi-cavity drainage.

[0044] Here, the above specific embodiment is only one of many drainage situations and does not constitute a specific limitation. By changing the state of the switching mechanism 20, it can be applied to different drainage needs or scenarios, which are not listed here one by one.

[0045] Embodiment 2

[0046] Reference Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0047] like Figure 5 and Figure 6 As shown, the outer wall of the switching cylinder 23 is rotatably matched with the inner wall of the shell 21, and a worm gear 41 is fixedly connected to the top of the switching cylinder 23, and the worm gear 41 is rotatably connected to the shell 21. The outer side of the worm gear 41 is meshingly connected with a worm 42, and the worm 42 is rotatably connected to the shell 21 through a ball bearing.

[0048] It should be noted that the worm wheel 41 and the worm 42 are separated from the switching cylinder 23 by a first partition fixedly connected to the inner wall of the shell 21, so as to prevent the body fluid flowing through the shell 21 from contacting the worm wheel 41 and the worm 42 and causing damage to the worm wheel 41 and the worm 42 (such as oxidation corrosion).

[0049] According to the above structure, the worm 42 rotates to drive the worm wheel 41 to rotate, and the worm wheel 41 drives the switching cylinder 23 to rotate, so that the operator can rotate the switching cylinder 23 by rotating the worm 42 from outside the shell 21, thereby facilitating the switching of the connection state formed by the combination of the drainage tube 22 and the switching hole 24.

[0050] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a rotating shaft 411 is fixedly connected to the inside of the worm gear 41, and the rotating shaft 411 is rotatably connected to the inner wall of the shell 21. The lower end of the rotating shaft 411 is fixedly connected to the switching cylinder 23. The upper end of the rotating shaft 411 extends out of the shell 21 and is fixedly connected to an indicator disk 412. Seven groups of indicator marks 413 are circumferentially arranged on the indicator disk 412, and the seven groups of indicator marks 413 correspond one-to-one to the seven groups of switching holes 24 respectively (that is, the seven groups of indicator marks 413 correspond one-to-one to the seven connection states of the switching mechanism 20), and an indicator block 414 is arranged on the outer side of the indicator disk 412, and the indicator block 414 is fixedly connected to the top of the shell 21 on one side close to the drainage tube 22.

[0051] It should be noted that the rotating shaft 411 passes through the interior of the first partition and adopts a mechanical shaft seal with the first partition. The mechanical shaft seal is a prior art, which is used to enable the rotating shaft 411 to rotate relative to the first partition while reducing the leakage of drainage materials through the gap between the rotating shaft 411 and the first partition. It will not be repeated here.

[0052] It should also be noted that the indicator block 414 is in the shape of a triangular arrow, and the indicator mark 413 includes scale lines and indicator patterns. The scale lines of the seven groups of indicator marks 413 correspond one-to-one to the seven groups of switching holes 24, respectively. The tip of the indicator block 414 is aligned with the scale lines, that is, the drainage tube 22 is aligned with the switching hole 24 at this time, which is convenient for improving the accuracy of the operator when rotating the switching cylinder 23. The indicator patterns of the seven groups of indicator marks 413 are different and correspond one-to-one to the seven groups of switching holes 24, respectively, which is convenient for the operator to understand the connection status of the current combination of the drainage tube 22 and the switching hole 24 through the indicator pattern when it is inconvenient to observe the rotation status of the switching cylinder 23 inside the shell 21.

[0053] It should also be noted that the indication pattern includes several circles, the number or position of circles in different indication patterns is different, and the number and position of the circles are distributed in the same manner as the number and position of the through holes of the corresponding switching hole 24, so that the operator can intuitively associate the indication pattern with the corresponding switching hole 24 through the indication pattern.

[0054] According to the above structure, the worm 42 is rotated, the worm 42 drives the worm wheel 41 to rotate, and the worm wheel 41 drives the indicator disk 412 to rotate relative to the housing 21, so that an indicator mark 413 is aligned with the indicator block 414. At this time, the switching hole 24 corresponding to the indicator mark 413 is aligned with the drainage tube 22, which is convenient for the operator to observe the connection status of the drainage tube 22 and the combination of the seven groups of switching holes 24 from the outside.

[0055] Among them, since the worm wheel 41 and the worm 42 are self-locking, the worm wheel 41 and the switching cylinder 23 can be rotated by rotating the worm 42, making it difficult for the switching cylinder 23 itself to rotate, thereby reducing the situation where the switching cylinder 23 rotates itself in the shell 21 and affects the opening and closing of the drainage tube 22.

[0056] like Figure 4 , Figure 5 and Figure 6 As shown, one end of the worm 42 extending out of the housing 21 is fixedly connected to a knob 421 , and a plurality of anti-slip grooves 422 are provided on the outer side of the knob 421 along the circumferential direction.

[0057] According to the above structure, the anti-slip groove 422 increases the friction between the operator's hand and the knob 421, making it easier for the operator to rotate the worm 42 by turning the knob 421 by hand.

[0058] like Figure 4 , Figure 5 and Figure 6 As shown, the surface of the knob 421 close to the housing 21 is roughened, and the surface of the housing 21 close to the knob 421 is roughened.

[0059] According to the above structure, although the worm wheel 41 and the worm 42 are self-locking, if the worm 42 itself rotates, the worm 42 will drive the switching cylinder 23 to rotate through the worm wheel 41, affecting the connection state between the drainage tube 22 and the switching hole 24. The surface is roughened to increase the friction between the knob 421 and the housing 21, thereby reducing the rotation of the knob 421 and the worm 42 itself and improving stability.

[0060] like Figure 5 and Figure 6 As shown, a driving assembly 32 is fixedly connected to the housing 21 , and an output end of the driving assembly 32 is fixedly connected to the stirring blade 31 .

[0061] It should be noted that the driving assembly 32 is a flat motor, which is separated from the switching cylinder 23 by a second partition fixedly connected to the inner wall of the shell 21. The output shaft of the flat motor passes through the second partition and enters the inner side of the switching cylinder 23 and is fixedly connected to the stirring blade 31. A mechanical shaft seal is used between the output shaft of the flat motor and the second partition. The mechanical shaft seal is a prior art and is used to enable the output shaft of the flat motor to rotate relative to the second partition while reducing the leakage of drainage materials through the gap between the output shaft and the second partition. It will not be repeated here.

[0062] According to the above structure, after the driving component 32 works, the output end drives the stirring blade 31 to rotate, so that the stirring blade 31 rotates relative to the switching cylinder 23 in the shell 21, which is convenient for breaking up the blockage in the drainage material and reducing the blockage.

[0063] like Figure 5 , Figure 6 and Figure 7 As shown, a plurality of protrusion assemblies 43 are fixedly connected to the inner wall of the switching cylinder 23 along the circumferential direction. The protrusion assemblies 43 include a plurality of protruding teeth 431 fixedly connected to the inner wall of the switching cylinder 23 along the axial direction.

[0064] It should be noted that the protruding assembly 43 is located on the inner side of the switching cylinder 23 , and the convex teeth 431 and the stirring blade 31 are staggered to avoid collision between the convex teeth 431 and the stirring blade 31 after rotation.

[0065] According to the above structure, when the stirring blade 31 rotates in the switching cylinder 23, the stirring blade 31 and the convex teeth 431 rotate relative to each other, so that the stirring blade 31 and the convex teeth 431 are constantly staggered with each other, which is convenient for stirring and breaking the blockage between the stirring blade 31 and the convex teeth 431, thereby reducing the blockage.

[0066] like Figure 4 and Figure 5 As shown, a plug assembly 212 is fixedly connected to one side of the housing 21 close to the drainage tube 22 , and the drainage tube 22 is detachably connected to the plug assembly 212 .

[0067] It should be noted that the plug assembly 212 is a pagoda head, which is a prior art. The end of the pagoda head is tapered to increase resistance after the drainage tube 22 is inserted, so as to fix the plug assembly 212 and the drainage tube 22.

[0068] According to the above structure, the drainage tube 22 and the shell 21 are detachably mounted together via the plug assembly 212, so that the drainage tube 22 can be easily replaced when the drainage tube 22 is blocked.

[0069] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the shell 21 is slidably connected to the drainage box 11, the outer side of the shell 21 is fixedly connected to a limit plate 213, the drainage box 11 is fixedly connected to a fixing plate 111, and screws 44 are detachably connected between the limit plate 213 and the fixing plate 111.

[0070] It should be noted that the limiting plate 213 is located on the side of the fixing plate 111 away from the body 10 , and the threaded end of the screw 44 passes through the limiting plate 213 and is threadedly engaged with the fixing plate 111 .

[0071] Furthermore, a connecting passage is provided inside the drainage box 11 and between the discharge hole 211 and the U-shaped pipeline, and the discharge hole 211 and the U-shaped pipeline are interconnected through the connecting passage.

[0072] According to the above structure, the shell 21 slides along the drainage box 11 toward the body 10, so that the limit plate 213 is close to the fixed plate 111, and the screw 44 is passed through the limit plate 213 and threadedly connected with the fixed plate 111, so that the shell 21 and the drainage box 11 are close to each other, and the discharge hole 211 is close to the connecting channel in the drainage box 11, so that the shell 21 is installed on the drainage box 11, so that the shell 21 and the drainage box 11 can be detachably installed together, which is convenient for replacing the shell 21 and the drainage box 11.

[0073] like Figure 5 , Figure 6 and Figure 8 As shown, a sealing ring 45 is provided between the discharge hole 211 and the drainage box 11 , and the sealing ring 45 is fixedly connected to the housing 21 .

[0074] It should be noted that a first groove is provided on the side of the discharge hole 211 close to the drainage box 11, and a second groove is provided on the side of the drainage box 11 close to the discharge hole 211. One side of the sealing ring 45 is fixedly embedded in the interior of the first groove, and the other side of the sealing ring 45 extends out of the first groove and slidably cooperates with the second groove.

[0075] According to the above structure, when the shell 21 is installed on the drainage box 11, the discharge hole 211 is close to the connecting channel of the drainage box 11, so that the sealing ring 45 extends out of one side of the first groove and slides into the second groove. In the process of the drainage material moving from the discharge hole 211 to the connecting channel, the leakage of the drainage material from the end surface where the shell 21 and the drainage box 11 are connected is reduced, thereby improving the sealing performance.

[0076] The working principle of the present invention is as follows: the drainage material enters the interior of the shell 21 through the three drainage tubes 22, and after the switching cylinder 23 is rotated, the different switching holes 24 are aligned with the three drainage tubes 22, thereby switching the connection state formed by the combination of the drainage tubes 22 and the switching holes 24, so that it is convenient to drain through any one or more of the three drainage tubes 22, thereby improving the convenience of drainage by multiple drainage tubes 22, and after the stirring blade 31 is rotated, it stirs the drainage material inside the shell 21, so as to break up the blockage in the drainage material and reduce the blockage during drainage.

[0077] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
