Description

Technical Field

[0001] This invention relates to the field of drainage device technology, and in particular to a portable, anti-permeability drainage device for clinical use in oncology. Background Technology

[0002] In clinical practice, existing oncology departments require the use of anti-permeability drainage devices. However, traditional drainage devices are inconvenient to carry and are easily damaged during transportation. Therefore, we propose a portable anti-permeability drainage device for clinical use in oncology departments.

[0003] An existing patent (publication number: CN110464888B) discloses a portable, anti-permeability drainage device for clinical use in oncology, including a carrying case. Slides are slidably connected to the inner walls of both sides of the carrying case. A first spring, fixed to the bottom side wall of the carrying case, is installed on the bottom side wall of the slide. The drainage device body is placed at the top of the slide. Grooves are formed on both inner walls of the carrying case. In implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved: While the device is easily moved by the operator using casters, making it convenient to carry, it needs to be fixed in one position during use. Each time the device is used, the operator needs to lock multiple casters sequentially using a locking mechanism, making positioning the device cumbersome. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is that the device needs to be fixed in one position and kept still during use. Each time the device is used, the operator needs to lock multiple casters in sequence through the locking mechanism, which makes positioning the device quite troublesome.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a portable, anti-permeability drainage device for clinical use in oncology, comprising... The stopping mechanism includes a base assembly, two sliding grooves, a buffer assembly, a diversion cylinder, a screw drive component, two arc-shaped clamping plates, two toothed plate drive components, two stop plates, and an intelligent control component. The two sliding grooves are symmetrically located on the top of the base assembly. The buffer assembly is located on the top of the base assembly. The diversion cylinder is fixedly connected to the end of the buffer assembly away from the base assembly. The screw drive component is located on the top of the base assembly. The two arc-shaped clamping plates are slidably connected to the inner walls of the two sliding grooves. The two toothed plate drive components are located at the bottom of the two arc-shaped clamping plates, with opposite sides of each arc-shaped clamping plate abutting against the outer wall of the diversion cylinder. The two stop plates are symmetrically located at the bottom of the base assembly. The two toothed plate drive components mesh with the two stop plates. The intelligent control component is located inside the diversion cylinder. A cleaning mechanism includes a scraping assembly, a spray pipe, a water storage chamber, a water pump, a drain pipe, a solenoid valve, and a collection box. The scraping assembly is rotatably inserted into one end of a drainage cylinder near a base assembly. The spray pipe passes through the scraping assembly and is fixedly connected to the interior of the drainage cylinder. The water storage chamber is located inside the base assembly. The water pump is located at the top of the base assembly. The outlet end of the water pump is fixedly inserted into the spray pipe. The inlet end of the water pump passes through the base assembly and extends into the interior of the water storage chamber. The collection box is movably inserted into the outer wall of the base assembly. The interior of the collection box is connected to the drainage cylinder via a drain pipe. The solenoid valve is located inside the drain pipe.

[0008] Based on the above technical features: the buffer assembly facilitates the assembly of the drainage tube onto the base assembly; the screw drive causes the two arc-shaped clamps and two toothed plate drive components to move synchronously; the two arc-shaped clamps cooperate to clamp and fix the drainage tube, thereby reducing the possibility of the drainage tube constantly shaking during use; and the toothed plate drive facilitates the movement of the stop plate and its contact with the ground, thereby increasing the friction between the device and the ground, and further reducing the possibility of the device shifting position during use.

[0009] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the base assembly includes a support plate, two roller rods and a pull rod. The pull rod is fixedly connected to the top of the support plate, and the two roller rods are symmetrically arranged at the bottom of the support plate. A rubber ring is fixedly sleeved on the outer wall of the roller rod, and the outer wall of the rubber ring abuts against the outer wall of the toothed plate transmission component.

[0010] Based on the above technical features: the two roller rods cooperate with the pull rod to facilitate the operator's movement of the device, thereby making it easy for the operator to carry the device.

[0011] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the number of buffer components is several, and the several buffer components are equally spaced in a ring between the base assembly and the drainage cylinder. Each buffer component includes a cylinder, a connecting rod, and a first spring. The cylinder is fixedly connected to the side of the support plate near the drainage cylinder, and the connecting rod is fixedly connected to the side of the drainage cylinder near the support plate. The first spring is disposed inside the cylinder, and the end of the first spring away from the cylinder abuts against the connecting rod. A limiting rod is movably inserted into the outer wall of the cylinder, and a second spring is disposed between the limiting rod and the outer wall of the cylinder. A vertical groove is formed on the outer wall of the connecting rod, and the limiting rod passes through the cylinder and is slidably connected to the inner wall of the vertical groove. An arc-shaped groove is formed on the outer wall of the cylinder, and a hollow ring is slidably connected to the inner wall of the arc-shaped groove. A groove is formed on the inner side of the hollow ring, and the inner side of the hollow ring slidably abuts against the end of the limiting rod away from the cylinder.

[0012] Based on the above technical features: the cylindrical shape facilitates the assembly of the connecting rod and the first spring; the first spring facilitates the damping treatment of the diversion tube; the arc-shaped groove facilitates the assembly of the hollow ring; and the contact between the hollow ring and the limiting rod causes the limiting rod to be inserted into the vertical groove, thereby facilitating the limiting treatment of the connecting rod and enabling the limiting rod to move up and down.

[0013] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the drainage tube includes a cylinder, a negative pressure device and a drainage tube. The negative pressure device is disposed on the outer wall of the cylinder, the air inlet of the negative pressure device is fixedly inserted into the outer wall of the cylinder, and the drainage tube is fixedly inserted into the top of the cylinder.

[0014] Based on the above technical features: the operation of the negative pressure device keeps the inside of the cylinder under negative pressure, and the accumulated liquid is then easily transported into the cylinder through the drainage pipe.

[0015] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the screw drive component includes a first motor, a double-threaded rod, and two limiting blocks. The two limiting blocks are symmetrically arranged on the top of the support plate. The two ends of the double-threaded rod are respectively rotatably inserted into the two limiting blocks. The first motor is arranged on the top of the support plate. The rotating shaft of the first motor is threadedly connected to one end of the double-threaded rod. The threads at both ends of the double-threaded rod are in opposite directions.

[0016] Based on the above technical features: the two limiting blocks facilitate the assembly of the double threaded rod, and the first motor facilitates the rotation of the double threaded rod, thereby causing the two arc-shaped clamps and the two toothed plate transmission components to move synchronously.

[0017] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the toothed plate transmission component includes a hollow plate, two toothed racks and an arc-shaped plate. The two toothed racks are symmetrically arranged on the outer side of the hollow plate, and the arc-shaped plate is fixedly inserted into the bottom of the hollow plate. The inner side of the arc-shaped plate abuts against the outer wall of the rubber ring.

[0018] Based on the above technical features: the movement of the hollow plate facilitates the synchronous movement of the two racks and the arc-shaped plate, and the contact between the arc-shaped plate and the rubber ring reduces the possibility of the roller rod rotating.

[0019] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the stop plate includes two gear nuts, two threaded rods and a rubber plate. The two gear nuts are both located at the bottom of the support plate and mesh with two racks respectively. The two threaded rods are threaded into the inner walls of the two gear nuts respectively. The rubber plate is fixedly connected to the end of the two threaded rods away from the gear nuts.

[0020] Based on the above technical features: the movement of the two racks facilitates the rotation of the two gear nuts, thereby causing the two threaded rods to move synchronously and drive the rubber plate to move. The downward movement of the rubber plate and its contact with the ground increases the friction between the device and the ground.

[0021] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the intelligent control component includes a pressure sensor, a liquid level sensor, a processor, a controller, and an alarm. The pressure sensor is fixedly inserted into the top of the drainage tube, and the liquid level sensor is disposed inside the drainage tube. The signal output terminals of both the pressure sensor and the liquid level sensor are connected to the signal input terminal of the processor via data cables. The signal output terminal of the processor is connected to the signal input terminal of the controller via data cables. The signal output terminal of the controller is connected to the signal input terminals of the alarm, the solenoid valve, and the negative pressure device via data cables.

[0022] Based on the above technical features: the air pressure sensor facilitates the detection of air pressure in the drainage tube. When the air pressure in the drainage tube is low, the signal is transmitted to the processor. The processor and controller then work together to control the alarm, thereby alerting the operator and enabling the operator to perform timely maintenance on the negative pressure equipment. The liquid level sensor facilitates the detection of the liquid level in the drainage tube. When a large amount of liquid is detected in the drainage tube, the signal is transmitted to the processor. The processor then works with the controller to stop the negative pressure equipment and open the solenoid valve, thus facilitating the drainage of the liquid in the drainage tube.

[0023] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the scraping assembly includes a second motor, a drive gear, a hollow shaft, a driven gear, and several scraping plates. The second motor is disposed on the top of the drainage tube. The drive gear is fixedly sleeved on the outer wall of the rotating shaft of the second motor. The hollow shaft is rotatably inserted into the top of the drainage tube. The driven gear is fixedly sleeved on the outer wall of the hollow shaft. The driven gear meshes with the drive gear. Several scraping plates are evenly distributed in a ring on the outer wall of the hollow shaft. The scraping plates are slidably connected to the inner wall of the drainage tube.

[0024] Based on the above technical features: the second motor can easily drive the active gear to rotate and drive the driven gear and hollow shaft to rotate. The hollow shaft can easily drive several scraping plates to rotate, thereby facilitating the scraping of the accumulated liquid adhering to the inner wall of the drainage tube.

[0025] As a preferred embodiment of the portable anti-permeability drainage device for clinical use in oncology according to the present invention, the spray pipe includes a guide pipe, a plurality of nozzles and a bushing. The guide pipe passes through a hollow shaft and is fixedly connected to the inner wall of the drainage tube. The plurality of nozzles are distributed in a ring at equal intervals on the outer wall of the guide pipe. The inlet end of the water pump is fixedly inserted into the guide pipe. The bushing is fixedly sleeved on the outer wall of the guide pipe. The end of the scraper away from the hollow shaft is fixedly connected to the outer wall of the bushing.

[0026] Based on the above technical features: the water pump facilitates the delivery of clean water into the guide pipe, which then supplies water to several nozzles. The nozzles spray clean water to rinse the inner wall of the guide pipe, while a scraper plate scrapes the inner wall of the guide pipe.

[0027] In summary, the present invention has at least one of the following beneficial effects: 1. The two arc-shaped clamps work together to hold and fix the drainage tube, thereby reducing the possibility of the drainage tube constantly shaking during use. The toothed plate transmission component facilitates the movement of the stop plate and its contact with the ground, thereby increasing the friction between the device and the ground, further reducing the possibility of the device shifting during use, and making the device easier to position. 2. The water pump facilitates the delivery of clean water from the water storage chamber to the spray pipe fittings, which then sprays clean water to rinse the inner wall of the drainage tube. At the same time, the scraping component facilitates scraping the inner wall of the drainage tube, making it easier to clean the inside of the drainage tube. 3. By rotating the hollow ring, the groove is made to coincide with the limiting rod. At this time, the second spring makes it easy to push the limiting rod to move and separate it from the vertical groove, thereby causing the connecting rod to lose its limit, which makes it easier for the operator to disassemble the diversion tube. 4. The air pressure sensor facilitates the detection of air pressure inside the drainage tube. When leakage occurs in the drainage tube, the air pressure inside the tube continuously decreases. At this time, the air pressure sensor can transmit the signal to the processor. The processor and controller then work together to control the alarm, thereby alerting the operator and enabling the operator to perform timely maintenance on the negative pressure equipment.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0041] Reference Figure 1-9This is the first embodiment of the present invention, which provides a portable anti-permeability drainage device for clinical use in oncology, including a stop mechanism 100, which includes a base assembly 101, two sliding grooves 102, a buffer assembly 103, a drainage tube 104, a screw drive component 105, two arc-shaped clamps 106, two toothed plate drive components 107, two stop plates 108, and an intelligent control component 109. The two sliding grooves 102 are symmetrically arranged on the top of the base assembly 101. The base assembly 101 includes a support plate 101a, two roller rods 101b, and a pull rod 101c. 1c is fixedly connected to the top of the support plate 101a, and two roller rods 101b are symmetrically arranged at the bottom of the support plate 101a. A rubber ring 101d is fixedly sleeved on the outer wall of the roller rod 101b. The outer wall of the rubber ring 101d abuts against the outer wall of the toothed plate transmission component 107. The two roller rods 101b cooperate with the pull rod 101c to facilitate the operator to move the device, thereby facilitating the operator to carry the device. When the toothed plate transmission component 107 moves, it can abut against the roller rods 101b, thereby reducing the possibility of the roller rods 101b rotating and causing the device position to shift.

[0042] A buffer assembly 103 is disposed on top of the base assembly 101. Several buffer assemblies 103 are arranged in a ring at equal intervals between the base assembly 101 and the drainage cylinder 104. Each buffer assembly 103 includes a cylinder 103a, a connecting rod 103b, and a first spring 103c. The cylinder 103a is fixedly connected to the side of the support plate 101a near the drainage cylinder 104, and the connecting rod 103b is fixedly connected to the side of the drainage cylinder 104 near the support plate 101a. Spring 103c is disposed inside cylinder 103a. The end of the first spring 103c away from cylinder 103a abuts against connecting rod 103b. Limiting rod 103d is movably inserted into the outer wall of cylinder 103a. A second spring 103e is disposed between limiting rod 103d and the outer wall of cylinder 103a. Vertical groove 103f is formed on the outer wall of connecting rod 103b. Limiting rod 103d passes through cylinder 103a and slides through the inner wall of vertical groove 103f. Arc-shaped groove 10 is formed on the outer wall of cylinder 103a. A hollow ring 103h is slidably connected to the inner wall of the arc-shaped groove 103g. A groove 103i is formed on the inner side of the hollow ring 103h. The inner side of the hollow ring 103h slidably abuts against the end of the limiting rod 103d away from the cylinder 103a. The cylinder 103a facilitates the assembly of the connecting rod 103b and the first spring 103c. The first spring 103c facilitates the damping treatment of the drainage cylinder 104. The arc-shaped groove 103g facilitates the assembly of the hollow ring 103h. When the 3h ring comes into contact with the limiting rod 103d, the limiting rod 103d is inserted into the vertical groove 103f, which facilitates the limiting treatment of the connecting rod 103b. At the same time, the limiting rod 103d can move up and down. By rotating the hollow ring 103h, the groove 103i is made to coincide with the limiting rod 103d. At this time, the second spring 103e is used to push the limiting rod 103d to move and separate it from the vertical groove 103f, thereby causing the connecting rod 103b to lose its limiting position, which makes it easier for the operator to disassemble the diversion tube 104.

[0043] The drainage tube 104 is fixedly connected to the end of the buffer assembly 103 away from the base assembly 101. The drainage tube 104 includes a cylinder 104a, a negative pressure device 104b, and a drainage pipe 104c. The negative pressure device 104b is disposed on the outer wall of the cylinder 104a. The air inlet end of the negative pressure device 104b is fixedly inserted into the outer wall of the cylinder 104a. The drainage pipe 104c is fixedly inserted into the top of the cylinder 104a. The operation of the negative pressure device 104b keeps the inside of the cylinder 104a under negative pressure, and the drainage pipe 104c facilitates the delivery of the accumulated liquid into the inside of the cylinder 104a.

[0044] The screw drive component 105 is located on the top of the base assembly 101. The screw drive component 105 includes a first motor 105a, a double threaded rod 105b, and two limiting blocks 105c. The two limiting blocks 105c are symmetrically arranged on the top of the support plate 101a. The two ends of the double threaded rod 105b are respectively rotatably inserted into the two limiting blocks 105c. The first motor 105a is located on the top of the support plate 101a. The rotation shaft of the first motor 105a is threadedly connected to one end of the double threaded rod 105b. The threads at both ends of the double threaded rod 105b are in opposite directions. The two limiting blocks 105c facilitate the assembly of the double threaded rod 105b. The first motor 105a facilitates the rotation of the double threaded rod 105b, thereby causing the two arc-shaped clamping plates 106 and the two toothed plate drive components 107 to move synchronously.

[0045] Two arc-shaped clamping plates 106 are slidably connected to the inner walls of two sliding grooves 102 respectively. Two toothed plate transmission components 107 are respectively disposed at the bottom of the two arc-shaped clamping plates 106. The toothed plate transmission component 107 includes a hollow plate 107a, two racks 107b and an arc-shaped plate 107c. The two racks 107b are symmetrically disposed on the outer side of the hollow plate 107a. The arc-shaped plate 107c is fixedly inserted into the bottom of the hollow plate 107a. The inner side of the arc-shaped plate 107c abuts against the outer wall of the rubber ring 101d. The movement of the hollow plate 107a facilitates the synchronous movement of the two racks 107b and the arc-shaped plate 107c. The contact between the arc-shaped plate 107c and the rubber ring 101d reduces the possibility of rotation of the roller rod 101b, thereby reducing the possibility of positional deviation of the device during movement.

[0046] The two arc-shaped clamps 106 abut against the outer wall of the diversion tube 104 on opposite sides. Two stop plates 108 are symmetrically arranged at the bottom of the base assembly 101. Two geared transmission components 107 mesh with the two stop plates 108 respectively. Each stop plate 108 includes two gear nuts 108a, two threaded rods 108b, and a rubber plate 108c. The two gear nuts 108a are both located at the bottom of the bearing plate 101a, and mesh with the two racks 107b respectively. Each threaded rod 108b is threaded into the inner wall of the two gear nuts 108a. The rubber plate 108c is fixedly connected to the end of the two threaded rods 108b away from the gear nuts 108a. The movement of the two racks 107b facilitates the rotation of the two gear nuts 108a, thereby causing the two threaded rods 108b to move synchronously and drive the rubber plate 108c to move. The downward movement of the rubber plate 108c and its contact with the ground increases the friction between the device and the ground, thereby achieving the positioning of the device.

[0047] The intelligent control component 109 is located inside the drainage tube 104. The intelligent control component 109 includes a pressure sensor 109a, a liquid level sensor 109b, a processor 109c, a controller 109d, and an alarm 109e. The pressure sensor 109a is fixedly inserted into the top of the drainage tube 104, and the liquid level sensor 109b is located inside the drainage tube 104. The signal output terminals of both the pressure sensor 109a and the liquid level sensor 109b are connected to the signal input terminal of the processor 109c via data cables. The signal output terminal of the processor 109c is connected to the signal input terminal of the controller 109d via a data cable. The signal output terminal of the controller 109d is connected to the signal input terminals of the alarm 109e, the solenoid valve 206, and the negative pressure device 104b via data cables. The air pressure sensor 109a facilitates the detection of air pressure inside the drainage tube 104. When the air pressure inside the drainage tube 104 is low, the signal is transmitted to the processor 109c. Subsequently, the processor 109c, in conjunction with the controller 109d, controls the alarm 109e to operate, thereby alerting the operator and enabling the operator to promptly inspect and maintain the negative pressure equipment 104b. The liquid level sensor 109b facilitates the detection of the liquid level in the drainage tube 104. When a large amount of liquid is detected in the drainage tube 104, the signal is transmitted to the processor 109c. Subsequently, the processor 109c, in conjunction with the controller 109d, controls the negative pressure equipment 104b to stop operating and simultaneously controls the solenoid valve 206 to open, thereby facilitating the drainage of the liquid inside the drainage tube 104.

[0048] The cleaning mechanism 200 includes a scraping assembly 201, a spray pipe 202, a water storage chamber 203, a water pump 204, a drain pipe 205, a solenoid valve 206, and a collection box 207. The scraping assembly 201 is rotatably inserted into one end of the diversion tube 104 near the base assembly 101. The spray pipe 202 passes through the scraping assembly 201 and is fixedly connected to the inside of the diversion tube 104. The water storage chamber 203 is opened inside the base assembly 101. The water pump 204 is located on the top of the base assembly 101. The outlet end of the water pump 204 is fixedly inserted into the spray pipe 202. The inlet end of the water pump 204 passes through the base assembly 101 and extends into the inside of the water storage chamber 203. The collection box 207 is movably inserted into the outer wall of the base assembly 101. The inside of the collection box 207 is connected to the diversion tube 104 through the drain pipe 205. The solenoid valve 206 is located inside the drain pipe 205.

[0049] In summary, the buffer assembly 103 facilitates the assembly of the drainage tube 104 onto the base assembly 101. The operation of the screw drive 105 causes the two arc-shaped clamps 106 and the two toothed drive 107 to move synchronously. The two arc-shaped clamps 106 cooperate to clamp and fix the drainage tube 104, thereby reducing the possibility of the drainage tube 104 constantly shaking during use. Furthermore, the toothed plate transmission component 107 facilitates the movement of the stop plate component 108 to contact the ground, thereby increasing the friction between the device and the ground and reducing the possibility of the device shifting position during use. Example

[0050] Reference Figure 7-8 This is the second embodiment of the present invention, based on the previous embodiment. The scraping assembly 201 includes a second motor 201a, a driving gear 201b, a hollow shaft 201c, a driven gear 201d, and several scraping plates 201e. The second motor 201a is disposed on the top of the diversion cylinder 104. The driving gear 201b is fixedly sleeved on the outer wall of the rotating shaft of the second motor 201a.
