Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is a fluid drainage device used for tumor care. Background Art

[0002] Because the long-standing tumor tissue will exert pressure on the surrounding blood vessels and lymphatic vessels, the fluid cannot flow back to the circulatory system normally, so it accumulates around the tumor and forms tumor effusion. Therefore, after tumor surgery, it is usually necessary to use a drainage device to suction the tumor effusion to reduce the patient's postoperative discomfort symptoms.

[0003] However, existing drainage devices usually use a puncture needle for puncture drainage. Since it takes a long time to fix the puncture needle, it is necessary to ensure stability during drainage. At the same time, during the drainage process, due to the influence of the pressure balance of the liquid inside and outside the suction body, excessive suction and suction reflux can easily cause secondary damage to the patient. Therefore, the present invention provides a fluid drainage device that is simple to use and operate to balance the suction speed during the suction process. Summary of the invention

[0015] The current generated by the first measuring component or the second measuring component is used to control the first electromagnet or the second electromagnet to adjust the displacement of the central rod, thereby adjusting the diameter change of the suction tube to form different sizes of slowing down the flow inside the suction tube, so as to maintain stable suction during the suction process.

[0016] When reverse flow occurs in the suction device, the second measuring component is electrically connected to the first electromagnet or the second electromagnet through the toggle component to achieve the closure of the suction tube, reduce the generation of effusion backflow, reduce the real-time attention of medical staff, and reduce the difficulty of operation.

[0017] Furthermore, the suction end includes a shell, an adsorption chamber is opened in the shell, one side of the adsorption chamber is connected to the suction pipe, and the other side of the adsorption chamber is connected to a negative pressure pipe, and one end of the negative pressure pipe away from the adsorption chamber is detachably connected to a negative pressure machine for generating negative pressure suction;

[0023] The controller is used to compare the gas flow data with the set airtightness value. If the gas flow data is greater than the airtightness value, a maintenance instruction is sent to the three-phase solenoid valve. If the gas flow data is less than the airtightness value, a switching instruction is sent to the three-phase solenoid valve.

[0024] Beneficial effects: The residual air in the trachea is determined by the gas flow data, and the flow of the gas flow is used to determine whether the device can be adsorbed, and then the working condition of the three-phase solenoid valve is controlled to ensure that the suction cup is fixedly adsorbed on the tumor and the stability during the suction process is ensured, so that it is convenient for medical staff to use.

[0025] Further, the toggle assembly includes an L-shaped toggle switch, one end of the toggle switch is rotatably matched with the first plate, and a torsion spring for resetting is provided between the toggle switch and the first plate;

[0026] A first contact and a second contact are respectively provided on both sides of the toggle switch, the toggle switch is electrically connected to the second measuring component, the first contact is grounded, and the second contact is electrically connected to the first electromagnet;

[0027] A limit rod is abutted against the bottom of the toggle switch; when the toggle switch is in a normal state, the toggle switch is located between the first contact and the second contact, and the limit rod is located below the toggle switch; when the first electromagnet is energized, the toggle switch contacts the first contact, and the limit rod is located below the toggle switch; when the first electromagnet is de-energized, the toggle switch contacts the second contact, and the limit rod is located on one side of the toggle switch.

[0028] Beneficial effect: the toggle switch is attracted by the adsorption force generated by the first electromagnet when it is working to control the connection status of the second measuring component. When backflow occurs in the suction tube and the first electromagnet is briefly powered off, the torsion spring is reset and drives the toggle switch to rotate, causing a certain misalignment between the toggle switch and the limit rod so that the limit rod blocks the toggle switch, thereby electrically connecting the second measuring component to the electromagnet to ensure that the second electromagnet adsorbs the baffle to block the suction tube.

[0029] Furthermore, the shell includes a first plate and a second plate, a plurality of clamping rods are arranged between the first plate and the second plate, one end of the clamping rod is fixedly connected to the first plate, and the other end of the clamping rod is slidably matched with the second plate; and an auxiliary airway is opened inside the clamping rod, one end of the auxiliary airway is connected to the outside, and a plug is detachably connected inside the auxiliary airway, and the other end of the auxiliary airway is connected to the suction pipe;

[0031] Beneficial effect: The auxiliary air channel and the auxiliary air hole are provided to form an internal and external air pressure difference, so that the first plate and the second plate are pressed more tightly, thereby improving the sealing performance of the suction tube.

[0033] Beneficial effect: During the rotation of the fan blades, the water flow formed by the hook shape squeezes the airbag, causing an instantaneous increase in pressure inside the airbag to discharge the air, thereby generating bubbles to increase the gap in the suction pipe, thereby ensuring the smooth flow of the suction pipe.

[0034] Furthermore, an air pressure sensor is provided in the airbag, and the air pressure sensor is used to measure the air pressure change data of the airbag in real time and send the air pressure change data to the controller;

[0035] The controller is also used to calculate the change value corresponding to the air pressure change data before and after the current time, and compare the change value with the set standard value. If the air pressure data is greater than or equal to the standard value, a maintenance instruction is sent to the negative pressure machine; if the air pressure data is less than the standard value, an output increase instruction is sent to the negative pressure machine.

[0036] Beneficial effect: The air pressure change data is used to determine whether the water flow data inside the suction pipe at the current time reaches the standard value, and then the suction condition of the negative pressure machine is adjusted to ensure the smooth flow inside the suction pipe.

[0037] Furthermore, the controller is also used to record a comparison value when the air pressure data is greater than or equal to the standard value during an interval time period, and then compare the comparison value during the current interval time period with the set rated value. If the comparison value is greater than the rated value, a maintenance instruction is sent to the negative pressure machine; if the comparison value is less than the rated value, a stop instruction is sent to the first electromagnet.

[0038] Beneficial effect: By comparing the comparison value at the current time with the rated value, it is determined whether blockage occurs in the suction pipe, and the number of airbag compression and expansion times within the interval time period is determined. By maintaining the sending of instructions and stop instructions, the opening and closing of the aperture in the suction pipe at the current time is maintained to ensure the smooth flow of the suction pipe.

[0039] Furthermore, a plurality of brackets are hingedly connected below the support tube, and a recessed groove is formed on the support tube, the bracket is located in the recessed groove, and one end of the bracket is rotatably matched with the support tube; and a plurality of auxiliary rods are bolted to adjacent brackets.

[0040] Beneficial effects: The triangular support formed by the bracket and the auxiliary rod improves the stability of the support tube placement; at the same time, the concealing effect of the recessed groove reduces the space occupied by the device when not in use, making it easier to store the device.

[0041] Furthermore, the placement groove runs through both sides of the support tube, the placement groove is located above the recessed groove, rubber blocks are provided on both sides of the placement groove, the rubber blocks are symmetrically arranged with the placement groove as the center, and the rubber blocks are fixedly connected to the support tube.

[0059] The embodiment is basically as shown in the attached Figures 1 to 13 As shown: A fluid drainage device for tumor care, including a placement end 1 and a suction end 2, a suction tube 3 is provided between the placement end 1 and the suction end 2, and a plurality of suction cups 11 are arranged circumferentially on the placement end 1, and the suction cups 11 are connected to the suction end 2 through an air pipe (not shown in the figure).

[0060] A sealing assembly 4 is provided on the suction pipe 3. The sealing assembly 4 includes a shell, a center rod 7, a first electromagnet 41 and a second electromagnet 42. The shell is connected to the suction pipe 3. The center rod 7 is slidably matched with the shell. A baffle 71 for closing the suction pipe 3 is welded at one end of the center rod 7. The second electromagnet 42 is located below the suction pipe 3. A first measuring assembly 5 and a second measuring assembly 6 for hydroelectric power generation are provided on both sides of the sealing assembly 4. The first measuring assembly 5 is located in the suction pipe 3. The first measuring assembly 5 includes a fan blade 51. The tail of the fan blade 51 is in a hook shape. An air bag 52 is bonded inside the fan blade 51. The air bag 52 is located at the direction of the tail of the fan blade 51. The air bag 52 is connected to an air compressor for continuous ventilation through an air pipe. A pressure relief valve is connected between the air bag 52 and the suction pipe 3. The first measuring assembly 5 and the second measuring assembly 6 both include a hydroelectric generator set for hydroelectric power generation. The hydroelectric generator set is a prior art and will not be described in detail in this embodiment.

[0061] The second measuring component 6 is located at the liquid outlet end of the suction tube 3, the first electromagnet 41 is electrically connected to the first measuring component 5, the second electromagnet 42 is electrically connected to the second measuring component 6, and the second measuring component 6 is located in the adsorption chamber; and the second measuring component 6 is located below the suction tube 3 close to the adsorption chamber; and a retractable support tube 23 is welded at the center of the bottom of the outer shell, and a placement groove 24 for placing the collection tank is opened on the support tube 23, and a plurality of extension ports 25 are opened at the bottom of the outer shell, and the adsorption chamber is connected with the placement groove 24 through the extension port 25.

[0062] A plurality of brackets 231 are hingedly connected below the support tube 23, and a recessed groove 232 is formed on the support tube 23. The bracket 231 is located in the recessed groove 232, and one end of the bracket 231 is rotatably matched with the support tube 23; and a plurality of auxiliary rods (not shown in the figure) are bolted between adjacent brackets 231. The placement groove 24 runs through both sides of the support tube 23, and the placement groove 24 is located above the recessed groove 232. Rubber blocks 241 are provided on both sides of the placement groove 24, and the rubber blocks 241 are symmetrically arranged with the placement groove 24 as the center, and the rubber blocks 241 are bonded to the support tube 23.

[0063] The center rod 7 is also provided with a plurality of slots 72. In another embodiment, the slots 72 are stepped. The slots 72 are arranged in a stepped manner to ensure the stability of the block 73 when engaged, so as to facilitate the control of the diameter of the suction tube 3, so as to facilitate the drainage process of the effusion. The slots 72 are reduced in order from top to bottom, and the block 73 is slidably fitted in the slots 72. The first electromagnet 41 is located at one end of the block 73 away from the center rod 7, and a second spring 44 is provided between the block 73 and the first electromagnet 41. The first electromagnet 41 is sucked to reduce the resistance of the second spring 44 to the center rod 7, so as to reduce the friction between the block 73 and the center rod 7, so as to facilitate the movement of the center rod 7. The center rod 7 is also provided with a first spring 43, and the first spring 43 is located between the baffle 71 and the second spring 44.

[0064] The first electromagnet 41 is provided with a toggle assembly at one end away from the block 73, and the toggle assembly is used to control the second measuring assembly 6 to be electrically connected to the first electromagnet 41 or the second electromagnet 42. The toggle assembly includes an L-shaped toggle switch 8, one end of which is rotatably matched with the first plate, and a torsion spring for resetting is provided between the toggle switch 8 and the first plate. The toggle switch 8 is provided with a first contact 81 and a second contact 82 on both sides, and the toggle switch 8 is electrically connected to the second measuring assembly 6, the first contact 81 is grounded, and the second contact 82 is electrically connected to the first electromagnet 41.

[0065] There is a limit rod 83 at the bottom of the toggle switch 8; when the toggle switch 8 is in normal state, the toggle switch 8 is located between the first contact 81 and the second contact 82, and the limit rod 83 is located below the toggle switch 8; when the first electromagnet 41 is energized, the toggle switch 8 contacts the first contact 81, and the limit rod 83 is located below the toggle switch 8; when the first electromagnet 41 is de-energized, the toggle switch 8 contacts the second contact 82, and the limit rod 83 is located on one side of the toggle switch 8.

[0066] Among them, when the second spring 44 is in a normal state, the block 73 is against the center rod 7, and when the second spring 44 is in a compressed state, the block 73 is separated from the center rod 7; when the baffle 71 moves to the lowest point from the second electromagnet 42, the baffle 71 is located inside the suction tube 3; when the baffle 71 moves to the farthest point from the second electromagnet 42, the baffle 71 is located outside the suction tube 3.

[0067] The specific implementation process is as follows: First, after the puncture needle is used, the puncture needle is fixed on the placement end 1, so that the suction cup 11 of the placement end 1 contacts the patient's skin surface, and the suction cup 11 fixes the placement end 1 on the body surface through the suction force generated by the negative pressure machine to keep the device adsorbed and fixed. At the same time, the triangular support formed between the bracket 231 and the auxiliary rod is used to improve the stability of the placement of the support tube 23, and to provide support and increase space for the retractable support frame to form a drainage liquid level difference with different height differences, so as to facilitate the drainage of effusion. At the same time, the support frame provides support space for the placement of the collection tank, which is convenient for drainage replacement during use to reduce the possibility of infection during the collection process.

[0068] During the suction process of the suction pipe 3, the flow of water in the suction pipe 3 drives the first measuring component 5 and the second measuring component 6 to rotate, so as to form different currents to make the first electromagnet 41 or the second electromagnet 42 generate different suction forces. The suction force of the second electromagnet 42 on the baffle 71 shortens the diameter of the suction pipe 3 to limit the flow of water in the suction pipe 3, thereby slowing down the flow rate in the suction pipe 3. At the same time, the suction force of the first electromagnet 41 controls the moving distance of the block 73 to control the contact between the block 73 and the center rod 7, so as to reduce the limiting effect of the block 73 on the center rod 7, so as to facilitate the second electromagnet 42 to overcome the pulling force of the second spring 44 to absorb the center rod 7, thereby adjusting and controlling the baffle 71 to the diameter of the suction pipe 3.

[0069] When the water flow rate in the suction pipe 3 is faster, the current generated by the first measuring component 5 and the second measuring component 6 is stronger, the suction force generated by the first electromagnet 41 is stronger, the friction force of the center rod 7 receiving the block 73 is smaller, the suction force generated by the first electromagnet 41 is stronger, and the moving distance of the baffle 71 and the center rod 7 to overcome the second spring 44 is longer, so as to slow down the flow inside the suction pipe 3, so as to maintain stable suction during the suction process.

[0070] Before the suction device has reverse flow, the adsorption force generated by the first electromagnet 41 is used to attract the toggle switch 8 to control the connection status of the second measuring component 6. When the suction tube 3 has reverse flow, the first electromagnet 41 is briefly powered off, and the torsion spring is reset to drive the toggle switch 8 to rotate, so that the toggle switch 8 and the limit rod 83 are misaligned to a certain extent, and the limit rod 83 blocks the toggle switch 8, so that the second measuring component 6 is electrically connected to the electromagnet to ensure that the second electromagnet 42 adsorbs the baffle 71 to block the suction tube 3, reduce the generation of effusion backflow, reduce the real-time attention of medical staff, and reduce the difficulty of operation.

[0071] Example 2

[0072] The difference from the above embodiment is that it further includes a controller, the controller is electrically connected to a three-phase solenoid valve, the input end of the three-phase solenoid valve is connected to the negative pressure pipe 21, and the output end of the three-phase solenoid valve is connected to the air pipe and the suction pipe 3 respectively;

[0073] The trachea is also connected to a gas flow sensor, which is electrically connected to the controller; the gas flow sensor is used to detect the gas flow data in the trachea in real time and send the gas flow data to the controller;

[0074] The controller is used to compare the gas flow data with the set airtightness value. If the gas flow data is greater than the airtightness value, a maintenance instruction is sent to the three-phase solenoid valve. If the gas flow data is less than the airtightness value, a switching instruction is sent to the three-phase solenoid valve.

[0075] For example, in the initial state, the suction tube 3 is in an empty state. When the negative pressure machine is started and drives the gas in the trachea to flow, the larger the gas flow data is, the greater the residual air in the trachea is, and the placement end 1 is not fixed; thus, the flow of the gas flow data is used to determine whether the device can be adsorbed, and then the working condition of the three-phase solenoid valve is controlled to ensure the fixed adsorption of the suction cup 11 on the tumor and the stability during the suction process, so as to facilitate use by medical personnel.

[0076] Example 3

[0077] The difference from the above embodiment is that the shell includes a first plate and a second plate, and a plurality of clamping rods 45 are arranged between the first plate and the second plate, one end of the clamping rod 45 is welded to the first plate, and the other end of the clamping rod 45 is slidably matched with the second plate; and an auxiliary airway is opened inside the clamping rod 45, one end of the auxiliary airway is connected to the outside, and a plug is detachably connected inside the auxiliary airway, and the other end of the auxiliary airway is connected to the suction tube 3.

[0078] The clamping rod 45 is also provided with an auxiliary air hole, the auxiliary air channel is connected with the auxiliary air hole, and the auxiliary air hole is located at the junction of the first plate and the second plate, and a gasket is provided between the first plate and the second plate.

[0079] The specific implementation process is as follows: first, the first plate and the second plate are supported and fixed to provide installation space for the first electromagnet 41 and the second electromagnet 42, and at the same time, the first plate and the second plate are interlocked through the cooperation of the clamping rod 45 to ensure the convenience of disassembly, facilitate the subsequent cleaning of the suction tube 3 and the installation of internal parts, and improve the convenience of the device.

[0080] Since one end of the auxiliary airway is blocked by a plug, the other end of the auxiliary airway is connected to the suction tube 3, and the auxiliary air hole is located at the junction of the first plate and the second plate. Therefore, when the suction end 2 performs negative pressure suction, the auxiliary air hole is connected to enable it to suck the air at the junction of the first plate and the second plate. The air difference formed inside and outside the suction tube 3 makes the first plate and the second plate pressed more tightly to improve the sealing of the suction tube 3.

[0081] Example 4

[0082] The difference from the above embodiment is that an air pressure sensor is provided in the airbag 52, and the air pressure sensor is used to measure the air pressure change data of the airbag 52 in real time, and send the air pressure change data to the controller; the controller is also used to calculate the change value corresponding to the air pressure change data before and after the current time, and compare the change value with the set standard value. If the air pressure data is greater than or equal to the standard value, a maintenance instruction is sent to the negative pressure machine; if the air pressure data is less than the standard value, an output increase instruction is sent to the negative pressure machine.

[0083] The controller is also used to record a comparison value when the air pressure data is greater than or equal to the standard value during an interval time period, and then compare the comparison value during the current interval time period with the set rated value. If the comparison value is greater than the rated value, a maintenance instruction is sent to the negative pressure machine; if the comparison value is less than the rated value, a stop instruction is sent to the first electromagnet 41.

[0084] For example, as more impurities are present in the suction pipe 3, the water flow in the suction pipe 3 becomes less obvious, which reduces the impact of the water flow guided by the fan blades 51 on the airbag 52, thereby affecting the expansion of the airbag 52 and the air pressure change data. The air pressure change data is used to determine whether the water flow data in the suction pipe 3 at the current time reaches the standard value, and then the suction condition of the negative pressure machine is adjusted, thereby ensuring the smooth flow of the suction pipe 3.

[0085] Then, the number of times the airbag 52 is compressed and expanded within the interval time period is determined, and the sending of instructions is maintained to control the working condition of the negative pressure machine. The sending of instructions is stopped so that the first electromagnet 41 no longer adsorbs the block 73, so as to maintain the opening and closing condition of the aperture in the suction tube 3 at the current time to ensure the smooth flow of the suction tube 3.

[0086] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
