Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical auxiliary equipment, in particular to a clinical breast drainage device. Background Art
[0002] Clinical breast drainage is a treatment for breast diseases such as acute mastitis with abscess formation, postoperative breast effusion or hematoma. It involves draining pus, blood, or exudate accumulated within the lesion out of the body through incision and drainage, puncture and aspiration, or placement of a drainage tube. Its purpose is to remove the source of infection or abnormal fluid accumulation, relieve local pressure, prevent the spread of infection, and promote tissue repair and healing. During clinical breast drainage, by observing the dynamic changes in the amount, color, and nature of the drainage volume, it is possible to promptly understand the progression of the disease, judge the treatment effect and healing process, and decide when to remove the tube. Therefore, medical staff will record the drainage volume within a certain period of time.
[0003] After breast cancer treatment, the current process relies on medical staff verbally instructing accompanying personnel to drain the drainage fluid, record the drainage volume, and then convey this information to the medical staff. However, due to the limited professional knowledge and comprehension of some accompanying personnel, there are problems such as inaccurate drainage volume records and non-standard drainage care procedures, which in turn affect the medical staff's assessment of the patient's condition and even the normal recovery and healing of the patient's wound. Summary of the Invention

The blocking piece A is evenly distributed with flow holes A, and the blocking piece B is evenly distributed with flow holes B. The flow holes A and the flow holes B are staggered. An annular part is fixed on the inner wall of the three-way joint between the blocking piece B and the inflation tube. A spring is provided in the three-way joint, one end of the spring is fixed to the blocking piece B, and the other end is fixed to the annular part. Under the elastic action of the spring, the blocking piece B can be pushed to fit tightly against the blocking piece A to achieve sealing.
[0012] Preferably, the adjustment mechanism includes an electric push rod B and a guide rod. A bracket B is fixed on the top of the box. The electric push rod B is vertically fixed on the bracket B.

[0036] The embodiments of the present invention are described below with reference to the accompanying drawings.
[0037] Example 1
[0038] See also Figures 1-13 The present invention provides a breast clinical drainage device, comprising a box 1 and a drainage can 4, wherein the box 1 has a circular cross-section and a support leg 101 at the bottom of the box 1 so that the device can be stably placed. In addition, the box 1 can also be placed on a cart, or a handle can be provided on the top of the box 1 for handholding, thereby facilitating the patient to get out of bed and move around.
[0039] A rotating tray 2 that can be rotated and adjusted is provided at the bottom of the box body 1. A plurality of drainage cans 4 are placed in a circular array around the axis of the rotating tray 2. By rotating the rotating tray 2, the drainage cans 4 can be driven to move synchronously along a circular path.
[0040] Among them, two through-holes 12, a removal port 13 and an insertion port 11 are sequentially provided on the top of the box body 1 along the moving path of the drainage canister 4. The removal port 13 is used to take the drainage canister 4 out of the box body 1, and the insertion port 11 is used to put the drainage canister 4 into the box body 1;
[0041] Specifically, before connecting each pipeline, select the required number of drainage cans 4 according to the actual situation, and place the drainage cans 4 into the box body 1 through the insertion port 11 in sequence and place them on the rotating tray 2, so that the drainage cans 4 are arranged in a ring on the rotating tray 2. After one drainage is completed, the drainage cans 4 filled with drainage fluid are taken out from the removal port 13.
[0042] The top of the box body 1 is provided with a negative pressure suction mechanism 5, a piping system 6 and an adjustment mechanism 7 in sequence. The piping system 6 includes two plugs 61, and the positions of the two plugs 61 correspond one to one with the positions of the two through-holes 12. The top of the drainage canister 4 is provided with two sockets 41 for the plugs 61 to be inserted into.
[0043] The two plugs 61 are mounted on the cantilever 73 in the adjustment mechanism 7 . In addition, during one rotation cycle of the rotating tray 2 , the two sockets 41 on the top of each drainage canister 4 can pass through and align with the two plugs 61 in sequence.
[0044] When the rotating tray 2 rotates to drive one of the drainage cans 4 to move below the through-hole 12 and ensure that the two sockets 41 on the drainage can 4 are aligned with the two plugs 61, the adjustment mechanism 7 works to drive the two plugs 61 downward synchronously, and after passing through the two through-holes 12 and extending into the box body 1, they are finally aligned one by one and inserted into the sockets 41, thereby achieving communication between the drainage can 4 and the pipeline system 6;
[0045] Among them, the pipeline system 6 is connected with the negative pressure suction mechanism 5. Finally, the drainage cup 4, the negative pressure suction mechanism 5 and the pipeline system 6 form a negative pressure suction drainage pipeline. The negative pressure suction effect is generated by the operation of the negative pressure suction mechanism 5, and the pipeline system 6 can draw the accumulated fluid in the patient's body into the drainage cup 4.
[0046] After the predetermined time is reached, the two plugs 61 are driven upward and out of the socket 41 by the adjustment mechanism 7. Then, by rotating the tray 2, the drainage can 4 at the next position is driven to move below the through-hole 12. The above steps are repeated to perform continuous negative pressure drainage.
[0047] Example 2
[0048] See also Figure 10 and Figure 11 The difference between this embodiment and embodiment 1 is that:
[0049] The negative pressure suction mechanism 5 includes a piston cylinder 52, a piston body 53, a traction rod 54 and an electric push rod A55. A bracket A51 is fixed on the top of the box body 1. The piston cylinder 52 and the electric push rod A55 are fixedly mounted in parallel on the bracket A51. One end of the piston cylinder 52 is the suction end and is connected to the pipeline system 6.
[0050] Among them, the piston body 53 is matched and slidably installed inside the piston cylinder 52, the traction rod 54 is fixed on the side of the piston body 53, and slides through the side of the piston cylinder 52 away from the vacuum end to the outside, and the outer end of the traction rod 54 is fixedly connected to the telescopic end of the electric push rod A55 through a connecting arm 56.
[0051] By extending the electric push rod A55, the piston body 53 is driven to move toward the side away from the suction end of the piston cylinder 52, thereby achieving a negative pressure suction effect. Through the connection of the pipeline system 6, the accumulated fluid can be negatively pressure-sucked into the drainage tank 4.
[0052] Among them, the tail end of the cylinder body of the electric push rod A55 is close to the suction end of the piston cylinder 52, so that the electric push rod A55 and the piston cylinder 52 have overlapping lengths in the extension and contraction direction of the electric push rod A55. The connecting arm 56 is used to fix the traction rod 54 and the extension end of the electric push rod A55 to avoid the overall length of the negative pressure suction mechanism 5 being too long during the suction operation, thereby avoiding excessive space occupation and being conducive to the miniaturization design of the device structure.
[0053] like Figure 2 、 Figure 8 and Figure 11As shown, the piping system 6 also includes an inlet pipe 62, a drainage hose 63 and a suction pipe 64, wherein one plug 61 is connected to the inlet pipe 62, and the other plug 61 is connected to the suction pipe 64. The other end of the suction pipe 64 is connected to the suction end of the piston cylinder 52, and the other end of the inlet pipe 62 is connected to the drainage hose 63. The drainage hose 63 is a drainage tube implanted in the patient's body in the prior art and is directly discarded after the drainage is completed and the tube is removed.
[0054] A one-way valve A641 is installed inside the suction pipe 64 near the piston cylinder 52. Figure 11 As indicated by the arrow in the figure, the one-way valve A641 guides the flow from the suction pipe 64 to the piston cylinder 52 , thereby achieving a one-way flow guiding effect from the suction pipe 64 to the piston cylinder 52 .
[0055] When the regulating mechanism 7 drives the two plugs 61 downward to be inserted into the two sockets 41 on the drainage canister 4, the inlet pipe 62 and the suction pipe 64 are both connected to the drainage canister 4. When the piston body 53 is driven to move to form a negative pressure in the piston cylinder 52, a negative pressure suction path is formed in sequence through the drainage hose 63, the inlet pipe 62, the three-way connector 8, and the suction pipe 64. The accumulated fluid in the patient's body is sucked into the drainage hose 63 and flows into the three-way connector 8 through the inlet pipe 62, thereby achieving drainage.
[0056] The two plugs 61 are arranged at the same height and connected to the top of the drainage canister 4 , so the accumulated fluid will not enter the suction tube 64 at will.
[0057] Example 3
[0058] See also Figure 2 and Figure 13 The difference between this embodiment and embodiment 2 is that:
[0059] A three-way joint 8 is provided between the inlet pipe 62 and the drainage hose 63. The inlet pipe 62 and the drainage hose 63 are respectively connected to the connecting ports at both ends of the three-way joint 8 in a detachable manner. An inflation pipe 9 is detachably connected to the other connecting port on the outer peripheral wall of the three-way joint 8. The other end of the inflation pipe 9 is connected to the side of the piston cylinder 52 near the exhaust end. A one-way valve B91 is installed in the inflation pipe 9 near the three-way joint 8. Figure 13 As indicated by the arrow in the figure, the one-way valve B91 diverts the flow from the inflation tube 9 to the three-way connector 8, thus achieving a one-way diversion effect from the inflation tube 9 to the three-way connector 8;
[0060] A blocking piece A81 and a blocking piece B82 are provided in the three-way joint 8 between the drainage hose 63 and the inflation tube 9. The blocking piece A81 is fixed in the three-way joint 8, and the blocking piece B82 is slidably installed in the three-way joint 8 along the length direction of the three-way joint 8. The blocking piece A81 is evenly distributed with flow holes A811, and the blocking piece B82 is evenly distributed with flow holes B821. The flow holes A811 and the flow holes B821 are staggered. Specifically, when the blocking piece A81 and the blocking piece B82 are tightly fitted, the flow holes A811 are partially blocked by the non-flow holes B821 on the blocking piece B82, and the flow holes B821 are partially blocked by the non-flow holes A811 on the blocking piece A81, thereby achieving sealing. When the blocking piece A81 and the blocking piece B82 are away from each other, the blockage is cancelled, and the accumulated fluid can pass through the flow holes A811 and the flow holes B821.
[0061] An annular member 83 is fixed on the inner wall of the tee joint 8 between the blocking piece B82 and the inflation tube 9. A spring 84 is provided inside the tee joint 8. One end of the spring 84 is fixed to the blocking piece B82, and the other end is fixed to the annular member 83. Under the elastic action of the spring 84, the blocking piece B82 can be pushed to fit tightly against the blocking piece A81.
[0062] When the electric push rod A55 extends and drives the piston body 53 to move for negative pressure suction of the accumulated fluid, the accumulated fluid will not enter the inflation tube 9 under the unidirectional flow guidance of the one-way valve B91. At the same time, the negative pressure suction force overcomes the elastic force of the spring 84, prompting the blocking piece B82 to move away from the blocking piece A81, so that the accumulated fluid can flow smoothly into the drainage canister 4. At this time, the spring 84 is compressed and stored.
[0063] When the electric push rod A55 retracts and drives the piston body 53 to move toward the exhaust end of the piston cylinder 52, under the unidirectional flow guidance action of the one-way valve A641, the piston body 53 can compress the air in the piston cylinder 52 to the inflation tube 9, and the compressed air in the inflation tube 9 enters the three-way joint 8, and the negative pressure is canceled. Under the elastic reset action of the spring 84, the sealing piece B82 is pushed to seal tightly with the sealing piece A81, and finally the compressed gas enters the inlet pipe 62, and the accumulated liquid in the inlet pipe 62 can be pumped into the drainage tank 4, thereby accelerating the discharge of the accumulated liquid in the inlet pipe 62 into the drainage tank 4.
[0064] Furthermore, during a complete extension and retraction operation of the electric push rod A55, a suction and pressure process is completed. After the accumulated fluid in the patient's body is sucked into the drainage cup 4, the remaining accumulated fluid in the inlet tube 62 can be pressurized into the drainage cup 4, reducing the blockage caused by excessive accumulation of internal fluid and blood clots due to the long inlet tube 62, thereby ensuring smoother drainage of the accumulated fluid.
[0065] Example 4
[0066] See also Figure 12 The difference between this embodiment and embodiment 3 is that:
[0067] The adjustment mechanism 7 includes an electric push rod B72 and a guide rod 74. A bracket B71 is fixed to the top of the box body 1. The electric push rod B72 is vertically fixed on the bracket B71. The telescopic end of the electric push rod B72 is fixed to the cantilever 73.
[0068] The electric push rod B72 works in an extension and retraction manner. Its extension end, under the connection of the cantilever 73, can drive the momentum plug 61 to move up and down, providing effective drive for the upward and downward adjustment of the plug 61.
[0069] In addition, a vertical sliding hole 731 is provided on the cantilever 73, and the guide rod 74 is vertically fixed on the top of the box body 1 and slides through the sliding hole 731. The sliding cooperation between the guide rod 74 and the sliding hole 731 plays a guiding and limiting role, ensuring that the lifting and lowering process of the cantilever 73 and the plug 61 is smooth and stable enough.
[0070] In addition, the inlet pipe 62 and the suction pipe 64 are made of soft tubes, which have the ability to bend and deform to adapt to the lifting and lowering of the plug 61. The inflation pipe 9 is also made of a soft tube.
[0071] Example 5
[0072] See also Figure 6 The difference between this embodiment and embodiment 4 is that:
[0073] A rubber plug 411 is provided in each of the two sockets 41 at the top of the drainage can 4. Both rubber plugs 411 have a cross-shaped cutout 412 that matches the plug 61 for insertion. A scale line 42 is provided on the outer wall of each drainage can 4. The scale line 42 facilitates the accompanying personnel or medical staff to read the amount of fluid accumulated in the drainage can 4. When the plug 61 is not inserted into the cross-shaped cutout 412, the cross-shaped cutout 412 is tightly closed to achieve sealing of the socket 41.
[0074] like Figure 9 As shown, when the plug 61 is inserted into the cross-shaped incision 412, the inner wall of the cross-shaped incision 412 fits tightly with the outer wall of the plug 61, which also has a sealing effect, avoiding air leakage and affecting the negative pressure drainage effect.
[0075] Example 6
[0076] See also Figure 4 The difference between this embodiment and embodiment 5 is that:
[0077] A driving motor 21 is fixed to the bottom of the box body 1, and a shaft 22 is fixed to the end of the output shaft of the driving motor 21. The shaft 22 extends through the box body 1 and is fixed to the bottom of the rotating tray 2. When the driving motor 21 works, its output shaft can drive the rotating tray 2 to rotate under the connection with the shaft 22, providing stable drive for the position transfer and switching of the drainage can 4.
[0078] like Figure 4 As shown, a plurality of cartridge seats 3 for matching drainage canisters 4 are arranged in an array around the axis of the rotating tray 2. The drainage canister 4 is placed in the cartridge seat 3, and can be placed so that the drainage canister 4 deflects and slides above the rotating tray 2 when the rotating tray 2 rotates.
[0079] In addition, if Figure 7 As shown, a positioning block 31 is fixed on the inner bottom wall of each cylinder seat 3, and a positioning groove 43 that matches the positioning block 31 is provided at the bottom of each drainage cup 4. When the drainage cup 4 is placed in the cylinder seat 3, the pillow positioning block 31 is aligned and fits into the positioning groove 43, so that the drainage cup 4 can be positioned and placed. When the drainage cup 4 is moved to the bottom of the through-hole 12, it is ensured that the two driving motors 21 on its top can be aligned one by one with the insertion port 11 and the plug 61.
[0080] It is worth noting that the medical staff presets the working interval of the drive motor 21 according to the actual situation. For example, the interval is set to twelve hours, that is, every twelve hours, the drive motor 21 works once to drive the drainage can 4 to move and switch, that is, the drainage can 4 is replaced once every twelve hours, and then the accompanying person or medical staff takes out the drainage can 4 containing the accumulated fluid from the removal port 13 and records the amount of the accumulated fluid;
[0081] The rotating tray 2 rotates to drive the drainage can 4 for replacement, and there is no need to manually dump the accumulated fluid, which saves time and effort. In addition, the process of inserting the plug 61 into the socket 41 depends on the timing coordination of the rotating tray 2 rotating to drive the drainage can 4 to move and the adjusting mechanism 7 driving the plug 61 to rise and fall. No human participation is required, and the insertion connection accuracy is high.
[0082] In addition, the drainage tank 4 is a disposable consumable and is directly discarded after use. After the tube is removed, the adjustment mechanism 7 is used to drive the plug 61 upward and out of the box body 1, and the drainage hose 63 is removed from the three-way joint 8. The plug 61 connected to the suction pipe 64 is connected to the cleaning agent container. Through the repeated extension and contraction of the electric push rod A55, the cleaning agent flows through the suction pipe 64, the piston cylinder 52, the inflation tube 9, the three-way joint 8 and the inlet pipe 62 in turn, and is discharged from the plug 61 connected to the inlet pipe 62, so that the pipeline can be flushed and cleaned. After the flushing and cleaning is completed, the three-way joint 8 is separated from the inlet pipe 62 and the inflation tube 9, and the three-way joint 8 is directly discarded. Then the device is sterilized at high temperature for reuse.
[0083] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, so the present invention will not explain the control method and circuit connection in detail.
[0084] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
