Description

Technical Field

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

[0002] The incidence of abdominal tumors is on the rise worldwide, posing a serious threat to human health. During the treatment of abdominal tumors, ascites is a common and difficult complication, which is usually drained by puncture drainage.

[0003] According to the Chinese patent publication number CN116702993A, the patent provides a tumor pleural and abdominal effusion extraction device, including an effusion storage bin and an extraction tube. The lower end of the outer wall of the effusion storage bin is provided with an anti-falling airbag, and both ends of the inner cavity are provided with movable units. The movable units cooperate with the connecting units and the anti-flow units to prevent the effusion from flowing back. There is a limit roller on the top of the effusion storage bin, a positioning unit on the upper end of the extraction tube, and a movable mesh frame and a gravity ball in the middle of the movable unit. This avoids the problem of accidental dumping of the effusion bag causing backflow and affecting the extraction operation.

[0004] However, when the effusion is discharged, the patient's abdomen will rise and fall according to his own breathing, which will cause the needle and sterile towel to shake up and down more. At the same time, the effusion in the abdomen will gradually reduce the degree of abdominal bulge as it is discharged. At this time, the skin and flesh of the patient's abdomen will gradually become soft and collapsed, which is easy to tear and deform the skin and flesh, causing the needle to move loose and the effusion to leak from the wound, thus affecting the safety of the effusion discharge. Therefore, a tumor care effusion discharge device is proposed to solve the above problems. Summary of the invention

[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a tumor nursing fluid discharge device, which has the following beneficial effects: 1. The tumor nursing fluid discharge device adopts synchronous absorption of puncture site exudate. The recovery part can match the patient's breathing frequency to timely absorb the exudate from the ventral puncture site. The airbag of the recovery part is bonded between the anti-slip plate and the arc frame. A one-way valve is installed on the airbag interface and connected to the reflux pipe and the exudate pipe. An absorption hole is opened on the inner arc surface of the exudate pipe. When the patient inhales, the abdomen is lifted and squeezed to squeeze the anti-slip plate to exhaust the airbag. When exhaling, the airbag rebounds and expands under the action of the spring, providing negative pressure suction for the exudate pipe and the absorption hole, and timely removing the exudate from the puncture site wound to prevent the flow of effusion and contamination, keep the area around the patient's wound clean, and reduce the risk of infection.

[0017] 2. The tumor nursing fluid discharge device effectively prevents the collapse of abdominal skin and flesh. The setting of the anti-collapse part can effectively prevent the patient's abdominal skin and flesh from becoming soft and collapsing due to the discharge of effusion. A rotating rod is rotatably sleeved between the convex blocks in the middle of the arc surface of the arc-shaped frame of the anti-collapse part. One side of the rotating sleeve on the rotating rod is connected to the anti-collapse plate, and the other side is connected to the anti-detachment plate. A spring is provided between the anti-collapse plate and the arc-shaped frame. During the discharge of effusion, the spring can elastically compensate for the fit of the lifting to avoid excessive squeezing of the patient's skin and flesh. At the same time, the obtuse angle design between the anti-collapse plate and the anti-detachment plate increases the fit area with the patient's abdomen, and the arc surface end reduces the indentation on the skin and flesh. The two symmetrically arranged anti-collapse parts can synchronously lift both sides of the abdominal puncture port to prevent the soft abdominal skin and flesh from collapsing to one side, thereby ensuring the stability of the puncture needle and preventing it from shaking and dislocating due to the collapse of abdominal skin and flesh, thereby significantly improving the safety of the effusion discharge process.

[0018] 3. The tumor care fluid discharge device adopts adaptive unblocking of fluid in the drainage tube. The unblocking part can adapt to the patient's breathing frequency, intermittently unblock the fluid in the drainage tube, and effectively prevent blockage. The four slide bars of the unblocking part slide through one side of the top of the bracket respectively, and the top is connected to the pressure plate. A spring is arranged outside the slide bar, and six unblocking rods are fixed at the bottom of the pressure plate. When the patient breathes, the rocker arm swings up and down with the rotating sleeve. When the airbag is exhausted, the rocker arm presses the pressure plate to drive the unblocking rod to descend and squeeze the drainage tube to prevent blockage and slow flow of fluid. When the airbag inhales, the rocker arm moves away from the pressure plate, and the spring two pushes the pressure plate to reset. The unblocking rod moves away from the drainage tube, which improves the flow efficiency of the fluid, thereby realizing the function of adaptively unblocking the congested fluid in the drainage tube following the patient's breathing frequency, and ensuring the high efficiency of fluid discharge.

[0019] 4. The tumor care fluid discharge device adopts a reasonable method to constrain the direction of the drainage tube. The constraint part can effectively constrain the direction of the drainage tube to prevent the drainage tube from shifting or falling off due to accidental touch or stumbling. The bracket of the constraint part is fixed on the back of the base. The inclined surface on the top of the bracket is convenient for the flow of liquid in the drainage tube. A constraint groove is opened on the inclined surface, and fourteen side pieces are installed. Two magnets are hinged between adjacent side pieces. Magnet two and the inclined surface are attracted by opposite poles, so the drainage tube can be stably limited in the constraint groove. At the same time, the constraint buckle at the upper end of the inclined surface can prevent the drainage tube from warping and falling off, thereby ensuring the smooth drainage process.

[0020] 5. The tumor care fluid discharge device is adapted to the abdominal sizes of different patients. Through the design of the adjustment part, it can be flexibly adjusted according to the height and width of the abdominal bulge of different tumor patients. The two ends of the two-way screw are rotated and connected in the adjustment groove. The base is penetrated and handwheels are installed. The threaded outer walls on both sides are respectively threaded with sliders. Medical staff only need to rotate the handwheel to drive the two-way screw to rotate, and then adjust the distance between the sliders to achieve adaptation to the abdominal width of different patients, which greatly improves the versatility of the device.

[0025] In the present invention, in order to match the height and width of the abdominal bulge of different tumor patients, the adjustment part 2 of this case includes an adjustment groove 21, and the adjustment groove 21 is opened on the top of the base 1. The inner wall of the adjustment groove 21 is rotatably connected with a bidirectional screw 22. The two ends of the bidirectional screw 22 are respectively movable through the two sides of the base 1. The outer walls of the through ends on both sides of the bidirectional screw 22 are fixedly sleeved with hand wheels 23. The threaded outer walls on both sides of the bidirectional screw 22 are threadedly sleeved with sliders 24, and the two sliders 24 are slidably connected to the inner wall of the adjustment groove 21.

[0026] In the present embodiment, in order to further prevent the patient's abdominal bulge from decreasing after the discharge of the accumulated fluid, thereby causing the skin and flesh to become soft and collapse, the anti-collapse portion 3 of the present case includes an arc frame 31, and two protrusions 32 are fixedly connected to the middle part of the inner arc surface of the arc frame 31, and a rotating rod is rotatably sleeved between the two protrusions 32, and a rotating sleeve 33 is fixedly sleeved on the outer wall of the rotating rod, and an anti-collapse plate 34 is fixedly connected to one side of the outer wall of the rotating sleeve 33, and the anti-collapse plate 34 fits the lower part of the patient's abdomen for lifting, and a spring 1 is fixedly connected between the anti-collapse plate 34 and the inner arc surface of the arc frame 31, and the spring 1 elastically compensates for the fit of the lifting to avoid excessive squeezing of the skin and flesh, and an anti-slip plate 35 is fixedly connected to the other side of the outer wall of the rotating sleeve 33, and the anti-slip plate 35 fits the upper part of the patient's abdomen for suitable In response to the abdominal breathing rise and fall and the sterile towel being pressed to prevent loosening, one end of the rotating rod is fixedly connected to a rocker arm 36, and the rocker arm 36 turns up and down and swings according to the patient's breathing rise and fall. The bottom of the arc frame 31 is parallel to the slider 24 and is installed on the top of one of the sliders 24. The angle between the anti-collapse plate 34 and the anti-slip plate 35 is an obtuse angle, which can increase the fitting area. The ends of the anti-collapse plate 34 and the anti-slip plate 35 are both arc-surface structures, and the arc-surface reduces excessive indentations on the skin and flesh. There are two anti-collapse parts 3, and the two anti-collapse parts 3 can synchronously lift both sides of the ventral puncture port to prevent the soft abdominal skin and flesh from collapsing to one side. The arc frame 31 in the other anti-collapse part 3 is installed on the top of another slider 24, and the two anti-collapse parts 3 are symmetrically arranged with each other.

[0027] It is worth noting that in order to match the patient's breathing frequency and synchronously absorb the exudate from the ventral puncture port, the recovery part 4 of this case includes an airbag 41, which is bonded between the anti-slip plate 35 in one of the anti-collapse parts 3 and the arc frame 31. A one-way valve 42 is installed at the interface of the airbag 41. The airbag 41 is connected to a reflux pipe 43 through the one-way valve 42. The one-way valve 42 prevents the accumulated fluid sucked into the reflux pipe 43 from flowing back and spraying out. The end of the reflux pipe 43 is connected to a seepage pipe 44, and an absorption hole 45 is opened on the inner arc surface of the seepage pipe 44. The absorption hole 45 is blocked at the periphery of the puncture port to absorb the exudate. The two ends of the seepage tube 44 are sealed and fixedly connected with a magnet 46, the outer wall of the seepage tube 44 is bonded with a double-sided tape 47, and the double-sided tape 47 is used to stick to the skin and flesh to fix the seepage tube 44. There are two recovery parts 4, and the two recovery parts 4 can surround and block the periphery of the ventral puncture port to prevent the seepage from flowing and spilling. The airbag 41 in the other recovery part 4 is bonded between another anti-slip plate 35 and the arc frame 31. The two recovery parts 4 are symmetrically arranged with each other. The magnets 46 on the two seepage tubes 44 attract each other with opposite sexes, and the magnet 46 is used to improve the stability of the seepage tube 44.

[0028] It is worth mentioning that in order to further constrain the direction of the drainage tube and prevent accidental touch and stumbling, the restraint part 5 in this case includes a bracket 51, which is fixedly connected to the back of the base 1. An inclined surface 52 is arranged on the top of the bracket 51. The inclined surface 52 facilitates the flow of liquid in the drainage tube. A restraint groove 53 is opened on the inclined surface 52. Fourteen side pieces 54 are installed on the inclined surface 52. A magnet 2 55 is hinged between every two adjacent side pieces 54. Each magnet 2 55 is attracted to the inclined surface 52 with opposite poles. The drainage tube is arranged in the restraint groove 53 and is limited by the magnet 2 55 to prevent it from falling out. A restraint buckle 56 is fixedly connected to the upper end of the inclined surface 52, and the drainage tube is not easy to lift up and fall off after bypassing the restraint buckle 56.

[0029] In order to further adapt to the patient's breathing frequency and intermittently clear the accumulated fluid in the drainage tube to prevent blockage, the clearing part 6 of this case includes four slide bars 61, and each two slide bars 61 slide through the top side of the bracket 51 respectively. The top of the four slide bars 61 is fixedly connected with a pressing plate 62. The outer wall of each slide bar 61 is sleeved with a spring 2 63. The pressing plate 62 is elastically connected to the top of the bracket 51 through the spring 2 63. The bottom of the pressing plate 62 is fixedly connected with six clearing rods 64. The front side of the base 1 is an inclined structure. The structure has a slope that is convenient for resting between the patient's ventral side and back to improve stability. The bottom ends of the six dredging rods 64 are equidistant from the top of the inclined surface 52. The six dredging rods 64 are aligned with the constraint groove 53. The dredging rods 64 can simultaneously press down the outer wall of the drainage tube in the limit position. The two rocker arms 36 are both U-shaped structures and the ends extend to the rear side of the outer arc surface of each arc frame 31. The extended ends of the two rocker arms 36 are both in contact with the top of the pressure plate 62, and the rocker arms 36 flip to push the pressure plate 62 down.

[0030] Working principle: the patient lies flat on the bed, the base 1 is placed on the bed, the hand wheel 23 is rotated to drive the bidirectional screw 22 to adjust the distance between the sliders 24, thereby driving the two anti-collapse parts 3 to match the width of the patient's abdomen, and a sterile towel is laid on the patient's abdominal puncture site after disinfection, and the inclined surface of the base 1 is pressed against the patient's abdominal back, and the sterile towel is pressed against the patient's ventral skin through the anti-collapse plate 34 and the anti-stripping plate 35 to complete the fixation, and the puncture needle is inserted into the abdominal puncture site and connected to the drainage tube, and the exudate tube 44 is adhered to the periphery of the puncture site skin through the double-sided tape 47, and the two exudate tubes 44 are connected through the magnet 46. The anti-collapse plate 34 is fixedly assembled to surround the outside of the puncture needle. According to the patient's breathing frequency, when the patient inhales, the abdomen is lifted and squeezes the anti-slip plate 35, which flips with the rotating sleeve 33 as the axis, thereby squeezing the airbag 41. The airbag 41 is exhausted through the one-way valve 42. When the patient exhales, the abdomen contracts, and the elastic force of the spring 1 pulls the anti-collapse plate 34 and drives the anti-slip plate 35 to reset, so that the airbag 41 rebounds and expands, providing negative pressure suction for the reflux tube 43, the seepage tube 44 and the absorption hole 45. When seepage occurs at the puncture wound during the discharge of the accumulated fluid, the accumulated fluid will be sucked in time by the negative pressure suction to avoid the flow of the accumulated fluid and contamination.

[0031] As the accumulated fluid continues to be discharged, the height of the patient's abdomen, which is swollen due to the accumulated fluid, gradually decreases, and the abdominal skin and flesh gradually soften. Relying on the elastic force of spring 1, the anti-collapse plate 34 is always pushed to compensate for the fit of the ventral skin and flesh, and provide thrust to prevent the abdominal skin and flesh from collapsing quickly and causing the puncture needle to shake or misplace, and also prevent the puncture needle from falling quickly with the collapsed skin and flesh and accidentally touching and bumping against equipment, limbs, beds, etc., thereby further improving safety.

[0032] The movable end of the drainage tube bypasses the constraint buckle 56 and is set in the constraint groove 53, and is blocked and limited by the inclined surface 52 attracted by the magnet 2 55. The inclination angle of the inclined surface 52 is conducive to the flow of accumulated fluid in the drainage tube. Every time the patient breathes, the rocker arm 36 can be driven to flip and swing up and down by the flipping of the rotating sleeve 33. When the synchronous air bag 41 is exhausted, the rocker arm 36 presses the pressure plate 62 and drives the clearing rod 64 to descend and squeeze the drainage tube, avoiding the problem of clogging and slow flow of accumulated fluid in the drainage tube. When the air bag 41 inhales, the rocker arm 36 is away from the pressure plate 62, and the elastic force of the spring 2 63 is used to push the pressure plate 62 to reset upward, so as to prompt the clearing rod 64 to move away from the drainage tube to improve the flow efficiency of the accumulated fluid, thereby achieving the effect of adaptively clearing the congested accumulated fluid in the drainage tube following the patient's breathing frequency.
