Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a flushing device for nursing children's urology surgery. Background Art

[0002] Pediatric urology is a discipline that studies urinary system diseases in children, including diseases of the kidneys, ureters, bladders, urethra, prostate and other organs. Common diseases in pediatric urology are urinary tract infections, cystitis and urinary incontinence. Urinary tract infections and cystitis are often effectively treated by flushing the urinary system.

[0003] In the prior art, medical staff usually use a urinary system flushing device to flush the patient's bladder and urethra. For example, a Chinese patent with a publication number of CN117883653B discloses a urological bladder flushing device, which is connected to a telescopic sleeve through a flushing channel, an S-shaped channel, and a first liquid channel. Two extrusion members are close to each other to squeeze and crush the blockage, so that the flushing device remains unobstructed, and the stability and reliability of the flushing device during use are improved;

[0004] When the urological flushing device in the prior art is used, it is necessary to insert the flushing tube into the patient's bladder through the urethra. However, when the existing urological flushing device is used to flush the bladder and urethra of child patients, due to the narrow urethra and low tolerance of children, when the flushing tube is inserted into the bladder through the urethra, the flushing tube will rub against the inner wall of the urethra, causing great discomfort to the child patient, and it is easy to damage the inner wall of the patient's urethra, increasing the risk of urinary tract infection. At the same time, due to the low pain tolerance of children, during the insertion of the flushing channel, excessive discomfort will increase the child's resistance and resistance, and will also affect the normal operation of medical staff, thereby adversely affecting the urinary system flushing treatment effect.

[0045] like Figures 1 to 9 As shown, an embodiment of the present invention provides a flushing device for pediatric urology care, including a catheter 18, a lubrication assembly is arranged on the left side of the catheter 18, the lubrication assembly includes an extrusion part and a discharge part, the extrusion part includes a connecting plate 21 fixedly connected to the left end of the catheter 18, a rubber ring 22 is fixedly connected to the outer surface of the left end of the connecting plate 21, a top block 23 is fixedly connected to the right end of the rubber ring 22, a limiting plate 24 is fixedly connected to the inner surface of the top block 23, an elastic plate 26 is fixedly connected between the limiting plate 24 and the connecting plate 21, and a one-way air outlet pipe 27 is fixedly connected to the outer surface of the elastic plate 26.

[0046] The limiting plate 24 is in a circular ring shape, the discharge portion includes a silicone membrane 25 fixedly connected to the inner surface of the limiting plate 24, a discharge hole 28 is opened on the outer surface of the top block 23, the inside of the top block 23 is filled with lubricant, and the lubricating component is used to lubricate the inner wall of the patient's urethra.

[0047] The rubber ring 22 is distributed in a circular ring shape, the conduit 18 and the rubber ring 22 are both made of silicone material, the outer surface of the top block 23 is arc-shaped, the number of the one-way air outlet pipes 27 is several groups and distributed in a ring array, and the elastic plate 26 is distributed in a circular ring shape.

[0048] By adopting the above technical solution, when the urinary system flushing device is used, it is first necessary to push the catheter 18 through the patient's urethra into the bladder. When the catheter 18 moves in the patient's urethra, it will rub against the inner wall of the patient's urethra, which will cause certain discomfort to the patient, especially for children, whose tolerance is low. Excessive discomfort will increase the resistance and opposition of children during the urinary system flushing process. For this purpose, a lubricating component is provided. Before the catheter 18 penetrates the patient's urethra, a proper amount of lubricant is first filled into the top block 23. When the catheter 18 is inserted into the patient's urethra, , the catheter 18 will carry the top block 23 through the connecting plate 21 and the rubber ring 22 and enter the urethra at the same time. When the catheter 18 is inserted, the top block 23 will slide inside the patient's urethra before the catheter 18. During the insertion process, the top block 23 will be resisted by the inner wall of the urethra. At this time, the distance between the top block 23 and the connecting plate 21 will become smaller. The top block 23 will cooperate with the connecting plate 21 to squeeze the rubber ring 22 and the elastic plate 26. The elastic plate 26 can undergo a certain degree of elastic deformation. At this time, as the volume of the rubber ring 22 becomes smaller, the elastic plate 26 is located inside the rubber ring 22, and the right end The rubber ring 22 is fixedly connected to the connecting plate 21, and the right end of the elastic plate 26 is sealed by the connecting plate 21. The gas inside the rubber ring 22 will enter the inner side of the elastic plate 26 through the one-way air outlet pipe 27 on the surface of the elastic plate 26, and then the gas pressure inside the elastic plate 26 will increase. At this time, the silicone membrane 25 will expand toward the inside of the top block 23 under the action of the gas pressure inside the elastic plate 26. The lubricant on the inner wall of the top block 23 is discharged from the discharge hole 28 on the outer surface of the top block 23 to the outside of the top block 23 under the extrusion force of the silicone membrane 25, and is discharged along with the catheter 18 and the top block 23 inside the patient's urethra. Move and apply the lubricant to the inner wall of the urethra and the outer surface of the catheter 18, which can squeeze and expand the urethra through the top block 23 during the insertion of the catheter 18 to reduce the resistance during the insertion of the catheter 18, thereby reducing the probability of damage to the inner wall of the catheter during the insertion of the catheter 18. At the same time, by evenly applying the lubricant to the inner wall of the urethra, a lubricating effect can be generated between the catheter 18 and the urethra, thereby effectively reducing the discomfort during the insertion of the catheter 18, and further improving the cooperation of children in the urinary system cleaning process.

[0049] like Figure 1 and Figure 6 As shown, a perfusion component is provided at the lower end of the catheter 18, and the perfusion component includes a mounting seat 14 fixedly connected to the lower end of the catheter 18, the interior of the mounting seat 14 is hollow, and an infusion tube 13 is fixedly connected to the lower end of the mounting seat 14, and a liquid storage bag 11 is fixedly connected to the lower end of the infusion tube 13, and a pressure-stabilizing valve 12 is fixedly connected to the outer surface of the upper end of the liquid storage bag 11, and a dosing tube 19 is fixedly connected to the outer surface of the lower end of the mounting seat 14, and the liquid storage bag 11 is made of transparent silicone material.

[0050] The inner surface of the conduit 18 is fixedly connected to a partition 15, and the outer surface of the conduit 18 is provided with liquid outlet holes 16, and the number of the liquid outlet holes 16 is several groups and distributed in a ring array, and the inner surface of the liquid outlet holes 16 is fixedly connected to elastic paddles 17, and the elastic paddles 17 are arc-shaped, and the number of the elastic paddles 17 is several groups and distributed in a ring array.

[0051] By adopting the above technical solution, after the upper end of the catheter 18 is inserted into the patient's bladder, the operator squeezes the liquid storage bag 11, and the physiological saline in the liquid storage bag 11 enters the mounting seat 14 through the infusion tube 13. The pressure-stabilizing valve 12 on the outer surface of the liquid storage bag 11 can adjust the air pressure on the inner wall of the liquid storage bag 11, so that the pressure inside the liquid storage bag 11 is maintained within an appropriate range. At the same time, the corresponding anti-inflammatory and cleaning drugs are added to the mounting seat 14 through the drug adding tube 19. The anti-inflammatory and cleaning drugs are mixed with the physiological saline and enter the catheter 18. The partition 15 can block the inside of the catheter 18, so that the physiological saline mixed with the drug is discharged into the patient's bladder through the liquid outlet 16. An elastic paddle 17 is arranged inside the liquid outlet 16. When the pressure of the physiological saline discharged from the liquid outlet 16 is too high, the elastic paddle 17 will The elastic paddles 17 can buffer the water flow, thereby reducing the impact of the saline on the bladder when the saline enters the patient's bladder, thereby reducing the irritation to the patient's bladder, and helping to further reduce the discomfort during the urinary system flushing process. At the same time, the elastic paddles 17 can block the urine in the patient's bladder, reducing the probability of urine entering the catheter 18 through the liquid outlet 16. After the saline mixed with the drug is infused into the patient's bladder, the catheter 18 is taken out of the patient's urethra, and then the drug is discharged from the body through the patient's urethra. The drug contacts the patient's bladder and the inner wall of the urethra to flush and sterilize the patient's urinary system, thereby treating the infection of the patient's urinary system.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, a reflux assembly is provided on the upper side of the mounting seat 14, and the reflux assembly includes a connecting seat 45 fixedly connected to the outer surface of the upper end of the mounting seat 14, and the connecting seat 45 is located on the outer side of the conduit 18, and a mounting plate 42 is fixedly connected to the inner surface of the conduit 18, and the mounting plate 42 is arc-shaped, and a reflux pipe 41 is fixedly connected to the inner surface of the mounting plate 42, and the lower end of the reflux pipe 41 passes through the outer side of the mounting seat 14.

[0053] The outer surface of the mounting plate 42 is symmetrically provided with guide holes 43 , the upper end of the return pipe 41 passes through the left side of the partition 15 and is fixedly connected to the partition 15 , and the outer surface of the conduit 18 is located on the right side of the connecting plate 21 and is provided with a return hole 44 .

[0054] By adopting the above technical solution, after the catheter 18 and the top block 23 enter the patient's bladder, the lower end of the reflux pipe 41 is kept unobstructed, and the urine in the bladder will enter the catheter 18 through the reflux hole 44. The partition 15 and the mounting plate 42 inside the catheter 18 fix and support the reflux pipe 41. After the urine enters the catheter 18, it enters the reflux pipe 41 under the blocking effect of the partition 15, and then is discharged to the body through the reflux pipe 41, so as to empty the urine in the patient's bladder and reduce the contamination of the medicine by the urine in the bladder, thereby improving the flushing effect of the patient's urinary system. While the mounting plate 42 stably supports the reflux pipe 41, the guide holes 43 on its surface can ensure the stable delivery of the flushing medicine inside the catheter 18.

[0055] like Figure 5 and Figure 7 As shown, a limiting component is provided on the outside of the catheter 18, and the limiting component includes a notch 34 opened on the outside of the catheter 18, and a capsule 35 is fixedly connected to the inner surface of the notch 34, and the notch 34 and the capsule 35 are both annular, and an air guide tube 33 is embedded and fixedly connected to the inside of the catheter 18, and the upper end of the air guide tube 33 is connected to the inside of the notch 34.

[0056] The outer surface of the connecting seat 45 is fixedly connected with a support tube 31, the right end of the support tube 31 is connected to the inside of the air guide tube 33, the left end of the support tube 31 is fixedly connected with a mounting sleeve 32, the inner side of the support tube 31 is provided with a control valve, and the mounting sleeve 32 is engaged and connected with the syringe outlet.

[0057] By adopting the above technical solution, after the upper end of the catheter 18 is inserted into the patient's bladder, in order to improve the stability during the urinary system flushing process, the catheter 18 needs to be fixed and limited. After the upper end of the catheter 18 completely enters the bladder, the operator fixes the syringe and the mounting sleeve 32, and keeps the control valve inside the support tube 31 in an open state. Then the operator injects an appropriate amount of gas into the support tube 31 through the syringe, and the gas enters the airway 33 through the support tube 31. The gas is transported to the inner wall of the notch 34 through the airway 33. At this time, the balloon 35 inside the notch 34 expands outward under the action of gas pressure. The diameter of the annular balloon 35 after expansion is much larger than the diameter of the catheter 18. The catheter 18 is clamped into the patient's bladder through the balloon 35, thereby improving the placement stability of the catheter 18 during the urinary system flushing process, reducing the probability of the catheter 18 moving during the flushing process, and further reducing the patient's discomfort.

[0058] like Figure 4 and Figure 8As shown, an adjustment component is provided on the inner side of the mounting seat 14, and the adjustment component includes a sealing plate 51 fixedly connected to the inner surface of the mounting seat 14, a through groove 54 is opened on the outer surface of the sealing plate 51, a pin shaft 53 is fixedly connected to the inner surface of the through groove 54, and a flap 55 is rotatably connected to the outer surface of the pin shaft 53.

[0059] The outer surface of the mounting seat 14 is rotatably connected to a sealing ring 52 , the inner side of the sealing ring 52 is spirally connected to a push rod 56 , the push rod 56 is slidably connected to the outer surface of the upper end of the flap 55 , and the end of the push rod 56 away from the flap 55 is fixedly connected to a pull plate 57 .

[0060] By adopting the above technical solution, in order to adjust the medicine injection speed and meet the urinary system injection needs of children of different age groups, an adjustment component is set for this purpose. When the medicine injection amount needs to be adjusted, the operator rotates the sealing ring 52, and the push rod 56 is connected to the sealing ring 52 through the spiral transmission. As the sealing ring 52 rotates, the push rod 56 is driven to move. When the push rod 56 moves to the side of the flap 55, the push rod 56 squeezes the flap 55, causing the flap 55 to gradually flip into a horizontal state, and the pin shaft 53 inside the through groove 54 pushes the flap 55 is a rotation support. As the flap 55 is gradually turned over, the angle between the flap 55 and the sealing plate 51 gradually becomes smaller. The flap 55 is used to seal the through groove 54 on the outer surface of the sealing plate 51, so that the injection amount of the medicine is reduced, thereby improving the operating convenience of the flushing device to a certain extent. At the same time, by flexibly adjusting the injection amount of the medicine, the urinary system flushing needs of children of different age groups can be met. The pull plate 57 at one end of the push rod 56 can block and limit the position of the push rod 56, thereby adjusting and limiting the moving position of the push rod 56.

[0061] like Figure 6 and Fig. 9 As shown, a material equalizing assembly is provided on the outer surface of the conduit 18 near the connecting plate 21, and the material equalizing assembly includes a guide groove 61 opened on the outer surface of the conduit 18, and the guide groove 61 is distributed in a circular ring shape. A ball 62 is rotatably connected to the inner side of the guide groove 61, and a cavity 63 is embedded in the inner side of the ball 62. The ball 62 is made of elastic material, and an overflow groove 64 is opened on the outer surface of the ball 62. A collecting groove 65 is opened on the outer surface of the conduit 18, and the collecting groove 65 is connected with the inside of the guide groove 61.

[0062] By adopting the above technical solution, during the insertion of the catheter 18, the lubricant is squeezed out to the outer surface of the catheter 18 through the lubricating component, but the lubricant cannot be evenly applied to various areas of the catheter 18. For this reason, a material distribution component is provided. During the movement of the catheter 18, part of the lubricant will be collected and circulated to the inside of the guide groove 61 through the collecting groove 65. The guide groove 61 is distributed in a circular ring shape on the outer surface of the catheter 18. Part of the position of the ball 62 inside the guide groove 61 will protrude to the outside of the guide groove 61. Therefore, during the movement of the catheter 18, the ball 62 will roll in contact with the inner wall of the patient's urethra. The ball 62 The cavity 63 opened on the inner side can reduce the weight of the ball 62 to a certain extent, thereby improving the flexibility of the ball 62 during rotation. The lubricating oil inside the guide groove 61 is applied to the inner wall of the urethra through the overflow groove 64 on the surface of the ball 62. As the ball 62 rotates, the lubricant can be evenly applied. The ball 62 is made of elastic material and can produce a certain degree of elastic deformation. Therefore, the problem of excessive squeezing force between the ball 62 and the inner wall of the patient's urethra can be avoided to a certain extent. While improving the uniformity of lubricant application, it can also ensure the comfort of the catheter 18 during insertion.

[0063] The working process of the technical solution of the present invention is as follows:

[0064] First, the catheter 18 and the top block 23 are inserted into the patient's urethra and bladder. The gas inside the rubber ring 22 will enter the inner side of the elastic plate 26 through the one-way air outlet pipe 27 on the surface of the elastic plate 26. The lubricant on the inner wall of the top block 23 is discharged from the discharge hole 28 on the outer surface of the top block 23 to the outside of the top block 23 under the extrusion force of the silicone film 25. The lubricating oil inside the guide groove 61 is smeared on the inner wall of the urethra through the overflow groove 64 on the surface of the ball 62. As the ball 62 rotates, the lubricant can be evenly applied, which can produce a lubricating effect between the catheter 18 and the urethra, thereby effectively reducing the discomfort during the insertion of the catheter 18.

[0065] After the catheter 18 and the top block 23 enter the patient's bladder, the gas is transported to the inner wall of the notch 34 through the airway 33. After the annular capsule 35 is expanded, its diameter is much larger than the diameter of the catheter 18. The catheter 18 is clamped to the patient's bladder through the capsule 35. The urine in the bladder will enter the catheter 18 through the reflux hole 44. After entering the catheter 18, the urine enters the reflux pipe 41 under the blocking effect of the partition 15, and then is discharged to the body through the reflux pipe 41. Then the operator squeezes the liquid storage bag 11, and the physiological saline in the liquid storage bag 11 enters the mounting seat 14 through the infusion tube 13. The physiological saline mixed with the medicine is discharged into the patient's bladder through the liquid outlet 16, and then the medicine is discharged to the body through the patient's urethra. The patient's urinary system is flushed and sterilized by the contact between the medicine and the inner wall of the patient's bladder and urethra, thereby treating the infection of the patient's urinary system.

[0066] The adjusting component squeezes the flap 55 through the push rod 56, causing the flap 55 to gradually flip into a horizontal state, and seals the through groove 54 on the outer surface of the sealing plate 51 through the flap 55, so as to flexibly adjust the amount of medicine injection to meet the urinary system flushing needs of children of different age groups.

[0067] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0068] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
