Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a drainage device for postoperative care of critically ill patients in the ICU. Background Technology

[0002] Surgical patient care encompasses preoperative, intraoperative, and postoperative care. It is crucial for preventing intraoperative complications, ensuring surgical success, and preventing postoperative complications. Because patients' conditions and surgeries vary, nursing care for surgical patients has both commonalities and individual specificities. Postoperatively, it is important to keep the patient warm, and special attention should be paid to safety before the patient regains consciousness. The depth of anesthesia can be estimated by observing pupillary reflexes, pulse, and respiration. If the pupils are small, superficial reflexes are absent, the pulse is slow, and respiration is deep and even, it indicates that the anesthesia is still deep, and the patient will not wake up for a short time. Conversely, if the pupils are large or normal, the eyelash reflex has returned, eye movements are flexible, the pulse is slightly increased, and respiration is shallow and irregular, it indicates that the patient is about to wake up. At this time, the patient is prone to agitation, so their safety must be ensured. One to two days postoperatively, if the patient has no contraindications, they should be encouraged to get out of bed and move around. Early activity promotes the recovery of physical functions, increases respiratory depth, facilitates the drainage of tracheal secretions and reduces pulmonary complications, improves systemic blood circulation, aids in the recovery of intestinal and bladder function, and enhances the patient's confidence in their recovery.

[0003] Surgical care includes using drainage devices to drain fluid from the patient's body. Due to the different nature of the patient's symptoms, the state of drainage varies greatly. Ordinary non-powered drainage devices cannot effectively collect large volumes of fluid, while powered drainage devices generally provide stable negative pressure suction, which cannot cope with sudden changes in the patient's condition. If the patient's fluid decreases or the internal negative pressure is not detected in time, continued external negative pressure suction will cause discomfort to the patient. Summary of the Invention

[0004] The purpose of this invention is to provide a drainage device for postoperative care of critically ill patients in the ICU in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A drainage device for postoperative care of critically ill patients in the ICU includes a monitoring mechanism for fixation, a storage mechanism for collecting fluid, and a traction mechanism for providing kinetic energy to the storage mechanism. The monitoring mechanism has a fixing mechanism at its upper end, the storage mechanism is fixed inside the fixing mechanism, one end of the storage mechanism is connected to a drainage mechanism, and the other end of the storage mechanism is connected to the traction mechanism through a connecting mechanism.

A processor and a communicator are installed inside the base. The fixing mechanism includes a fixing seat and a latch. The fixing seat is fixed to the upper end of the base. There are two fixing seats, and each fixing seat has a latch at both the front and rear ends of its upper end. The storage mechanism includes a disposable liquid storage bottle, a drain connector, and an internal sliding bowl. The disposable liquid storage bottle is fixed between the latches. The drain connector is provided at one end of the disposable liquid storage bottle, and the internal sliding bowl is provided inside the disposable liquid storage bottle. The drainage mechanism includes a tube connector, a drainage tube, a second fixing seat, and an anti-clogging head. The drainage tube is connected to the drainage connector and the second fixing seat through the tube connector. A sterile tube is provided at one end of the second fixing seat, and the anti-clogging head is provided at the top end of the sterile tube. An airbag ring is provided between the sterile tube and the anti-clogging head. A traction rope is provided inside the second fixing seat and the sterile tube. One end of the traction rope is connected to the anti-clogging head end inside the sterile tube, and the other end of the traction rope is connected to a hand roller. An internal tube is provided through the second fixing seat and the sterile tube, and the internal tube connects the anti-clogging head and the drainage tube. The traction mechanism includes a limiting tube, a traction tube, a traction seat, and a pulling seat. The limiting tube is fixed on the fixed seat, with its upper half on the upper side of the fixed seat and its lower half on the lower side of the fixed seat. A traction hose composed of several traction tubes is arranged inside the limiting tube. The traction tubes are connected by connecting pins, and a limiting step is formed between two traction tubes. An elastic pull rope is connected between the top ends of both sides of the traction tube. One end of the traction tube is connected to the internal sliding cup via the connecting mechanism. The other end of the traction tube is provided with the traction seat. One end of the traction seat is connected to the pulling seat via a traction magnet. A slider is provided in the middle of the pulling seat, and a traction screw is connected to the slider. Traction slides are provided on both sides of the traction screw, and the power end of the traction screw is connected to a traction motor.

[0006] Preferably, the connecting mechanism includes a mating seat, a mating block, a first push rod, and a limiting ring. The mating seat is connected to the end face of the inner sliding cup, and the mating block is connected to the traction tube. Two first push rods are provided inside the mating block, and the limiting ring is provided on the first push rod. A return spring is provided between the limiting ring and the mating seat. A pushing sleeve is provided between the two first push rods, and a mating screw is connected inside the pushing sleeve. The power end of the mating screw is connected to a first motor.

[0007] With this configuration, after the traction tube is inserted into the disposable liquid storage bottle, the mating block engages with the mating seat. At this time, the first motor is controlled to extend the two limiting rings and engage with the mating block to lock them in place.

[0008] Preferably, the connecting mechanism includes a mating seat, a mating block, a second push rod, and a bidirectional screw. The mating seat is connected to the end face of the inner sliding cup, the mating block is connected to the traction tube, and two second push rods are provided inside the mating block. The second push rods are connected to the bidirectional screw, and a second motor is connected to the power end of the bidirectional screw.

[0009] With this configuration, after the traction tube is inserted into the disposable liquid storage bottle, the mating block engages with the mating seat. At this time, the second motor is controlled to cause the two second push rods to extend outward and engage with the mating block to lock together.

[0010] Preferably, the fixing seat is connected to the base by bolts, and the latch is connected to the fixing seat by bolts.

[0011] With this configuration, the latch is used to secure the disposable liquid storage bottle.

[0012] Preferably, the drainage connector is integrally formed into the disposable liquid storage bottle, and the internal sliding bowl is slidably connected to the disposable liquid storage bottle.

[0013] With this configuration, the internal sliding bowl slides inside the disposable liquid storage bottle, thereby generating negative pressure to draw the collected liquid into the disposable liquid storage bottle, making the traction pressure more stable.

[0014] Preferably, the tube connector is integrally formed into the drainage tube, the anti-clogging head is a semi-circular hollow sphere with through holes evenly distributed on its surface, and the airbag ring surrounds the sterile tubing.

[0015] With this configuration, the airbag ring is used for auxiliary support to adapt to different drainage environments, and the sterile tubing can be bent by the traction rope, thus facilitating fixation after being bent at different locations.

[0016] Preferably, the limiting step is integrally formed into the traction tube, and the traction tube can only be flipped downwards.

[0017] With this design, the limiting step restricts the traction tubes from folding downwards and prevents them from folding upwards, thus providing a certain degree of support.

[0018] Preferably, the traction magnet is connected to the pull seat by adhesive, and the traction magnet is an electromagnet, with a magnet installed on the traction seat.

[0019] With this configuration, the traction magnet is used to connect to the traction seat to pull the traction tube. When different safety forces are required, the number of energized traction magnets is controlled to adjust the safety force.

[0020] Preferably, the pull seat is connected to the slider by bolts, and the slider is connected to the traction screw by threads.

[0021] With this configuration, the slider works in conjunction with the traction screw to pull the traction tube and the internal sliding bowl, creating a negative pressure inside the disposable liquid storage bottle to assist in drainage.

[0022] Preferably, the mating seat is integrally formed on the inner sliding cup, the mating block is connected to the traction tube by screws, and the inner side of the mating seat is formed with a groove for mating with the first push rod.

[0023] This design, with its one-piece molding, ensures stability.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By using a traction mechanism in conjunction with a storage mechanism, a certain safety force can be set in certain load environments. When excessive negative pressure is generated at the patient end, the traction force can be disconnected in time, thereby improving safety. 2. By using a drainage mechanism in conjunction with a storage mechanism, flexible sterile tubing and variable-diameter airbag rings can be used to adapt to different drainage environments and improve drainage efficiency.

The processor and the communicator are installed inside the base 11. The fixing mechanism 2 includes a fixing seat 21 and a latch 22. The fixing seat 21 is fixed to the upper end of the base 11. There are two fixing seats 21, and each fixing seat 21 has a latch 22 at the front and rear ends of the upper end. The storage mechanism 3 includes a disposable liquid storage bottle 31, a drain connector 32, and an internal sliding bowl 33. The disposable liquid storage bottle 31 is fixed between the latches 22. One end of the disposable liquid storage bottle 31 is provided with a drain connector 32, and the inside of the disposable liquid storage bottle 31 is provided with an internal sliding bowl 33. The drainage mechanism 4 includes a tube connector 41, a drainage tube 42, a second fixing seat 43, and an anti-blocking head 44. The drainage tube 42 is connected to the drainage connector 32 and the second fixing seat 43 through the tube connector 41. A sterile tube 45 is provided at one end of the second fixing seat 43, and an anti-blocking head 44 is provided at the top of the sterile tube 45. An airbag ring 46 is provided between the sterile tube 45 and the anti-blocking head 44. A traction rope 48 is provided inside the second fixing seat 43 and the sterile tube 45. One end of the traction rope 48 is connected to the anti-blocking head 44 inside the sterile tube 45, and the other end of the traction rope 48 is connected to a hand roller 47. An internal tube is provided through the second fixing seat 43 and the sterile tube 45, and the internal tube is connected to the anti-blocking head 44 and the drainage tube 42. The traction mechanism 5 includes a limiting tube 51, a traction tube 52, a traction seat 53, and a pulling seat 54. The limiting tube 51 is fixed on the fixed seat 21, with the upper half of the limiting tube 51 on the upper side of the fixed seat 21 and the lower half on the lower side of the fixed seat 21. The limiting tube 51 is equipped with a traction hose composed of several traction tubes 52. The traction tubes 52 are connected by connecting pins 521, and a limiting step 522 is formed between two traction tubes 52. An elastic pull rope 523 is connected between the top two sides of the traction tube 52. One end of the traction tube 52 is connected to the internal sliding cup 33 through a connecting mechanism 6. The other end of the traction tube 52 is equipped with a traction seat 53. One end of the traction seat 53 is connected to the pulling seat 54 through a traction magnet 59. A slider 55 is provided in the middle of the pulling seat 54. A traction screw 56 is connected to the slider 55. Traction slide rods 58 are provided on both sides of the traction screw 56. The power end of the traction screw 56 is connected to a traction motor 57.

[0031] Preferably, the connecting mechanism 6 includes a mating seat 61, a mating block 62, a first push rod 63, and a limiting ring 64. The mating seat 61 is connected to the end face of the inner sliding cup 33, and the mating block 62 is connected to the traction tube 52. Two first push rods 63 are provided inside the mating block 62, and a limiting ring 64 is provided on each first push rod 63. A return spring 65 is provided between the limiting ring 64 and the mating seat 61. A pushing sleeve 66 is provided between the two first push rods 63, and a mating screw 67 is connected inside the pushing sleeve 66. The power end of the mating screw 67 is connected to a first motor 68. After the traction tube 52 is inserted into the disposable liquid storage bottle 31, the mating block 62... When the mating seat 61 is engaged, the first motor 68 is controlled to extend the two limit rings 64 and lock them in place with the mating block 62. The fixing seat 1 21 is connected to the base 11 by bolts, and the locking buckle 22 is connected to the fixing seat 1 21 by bolts. The locking buckle 22 is used to fix the disposable liquid storage bottle 31. The drainage connector 32 is integrally formed into the disposable liquid storage bottle 31, and the internal sliding bowl 33 is slidably connected to the disposable liquid storage bottle 31. The internal sliding bowl 33 slides inside the disposable liquid storage bottle 31, thereby generating negative pressure to draw the collected liquid into the disposable liquid storage bottle 31, making the traction pressure more stable. The tube connector 41 is integrally formed into the drainage tube 42, and the anti-blocking head 44 has a uniform surface. A semi-circular hollow sphere with through holes is evenly distributed. An air bladder ring 46 surrounds a sterile tubing 45. The air bladder ring 46 provides auxiliary support to adapt to different drainage environments. The sterile tubing 45 can be bent by the traction rope 48, allowing for easy fixation after bending at different points. A limiting step 522 is integrally formed on the traction tube 52, preventing the traction tube 52 from folding downwards. The limiting step 522 restricts the traction tube 52 from folding upwards, thus providing some support. A traction magnet 59 is glued to the pull seat 54. The traction magnet 59 is an electromagnet. A magnet is installed on the traction seat 53. Iron 59 is used to connect to traction seat 53 to pull traction tube 52. When different safety forces are required, the number of energized traction magnets 59 is controlled to adjust the safety force. Pull seat 54 is connected to slider 55 by bolts. Slider 55 is connected to traction screw 56 by threads. Slider 55 cooperates with traction screw 56 to pull traction tube 52 and internal sliding cup 33, so that negative pressure is formed inside disposable liquid storage bottle 31 to assist in drainage. Matching seat 61 is integrally formed in internal sliding cup 33. Matching block 62 is connected to traction tube 52 by screws. The inner side of matching seat 61 is formed with a groove for matching first push rod 63. The integral forming ensures stability.

[0032] Example 2 like Figure 10 The difference between this embodiment and Embodiment 1 is that: The connecting mechanism 6 includes a mating seat 61, a mating block 62, a second push rod 611, and a bidirectional screw 612. The mating seat 61 is connected to the end face of the inner sliding cup 33, and the mating block 62 is connected to the traction tube 52. Two second push rods 611 are provided inside the mating block 62. The second push rods 611 are connected to the bidirectional screw 612. The power end of the bidirectional screw 612 is connected to a second motor 613. After the traction tube 52 is inserted into the disposable liquid storage bottle 31, the mating block 62 mates with the mating seat 61. At this time, the second motor 613 is controlled to make the two second push rods 611 extend outward and lock with the mating block 62.

[0033] Working principle: The disposable storage bottle 31 is fixed on the fixing base 21. Due to the elastic pull rope 523, the traction tube 52 is taut when it is not limited by the limiting tube 51. The mating block 62 at the top of the extended traction tube 52 is inserted into the disposable storage bottle 31 to lock the internal sliding cup 33. Then, the tube connector 41 is connected. Depending on the condition of the drainage point, the curvature of the sterile tubing 45 and the degree of expansion of the airbag ring 46 are adjusted. The airbag ring 46 can also be expanded to a semi-circular part. After fixing the anti-blocking head 44, the safety force is adjusted to control the power supply. The number of magnets 59 is determined, and the traction motor 57 is started to drive the traction screw 56 to rotate, which pulls the traction tube 52 through the pull seat 54. This causes the traction tube 52 to drive the internal sliding bowl 33 to slide, creating a negative pressure inside the disposable liquid storage bottle 31. The accumulated fluid is then drawn into the disposable liquid storage bottle 31 through the drainage tube 42. When there is no accumulated fluid in the body and a negative pressure is created in the body, the traction magnet 59 is subjected to an instantaneous reverse force, which disconnects it from the pull seat 54 in time. This avoids the forced negative pressure suction causing discomfort to the patient. At the moment of disconnection, the processor and communicator inside the base 11 can promptly sound an alarm and provide a reminder.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
