Description

Technical Field

[0001] The present invention belongs to the technical field of anal dilators, and particularly relates to an adjustable pediatric general surgery anal dilator. Background Art

[0002] At present, some children may be born with anal stenosis or have anal stenosis due to trauma or other reasons, or may have anal incontinence problems due to incomplete muscle development. Therefore, it is necessary to use an anal dilator to expand the anus of children to correct such conditions.

[0003] However, when using an anal dilator for children at present, the anal dilator is mostly manually controlled by medical staff to insert the speed and insert it into the child's body. However, since the tissues in the anal and rectal regions of children are softer and more sensitive than those of adults, if the medical staff is inexperienced or inattentive, the manual insertion method may be too fast, which may cause laceration, tearing or increase the discomfort of children, thereby increasing the resistance of children to anal dilation and being inconvenient for actual use. At the same time, in order to prevent over-dilation and reduce discomfort, medical staff mostly gradually increase the diameter of the anal dilator and insert it into the child's body to gradually increase the diameter of the anus. However, this method requires more equipment for preparation and cleaning, and multiple insertions and extractions of the anal dilator will also increase the discomfort of children and the resistance to anal dilation. With more operation steps, it is also easy to take the wrong anal dilator, which is not convenient for use. In addition, medical staff mostly determine whether to replace the anal dilator with a larger diameter through the feedback of patients. However, some younger children have weaker understanding and comparison abilities of physical sensations and may not be able to accurately express their current feelings, easily resulting in the problem of replacing the larger anal dilator too early or too late, thereby causing anal laceration, tearing and longer treatment time, which is not convenient for the current actual situation. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable pediatric general surgery anal dilator to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: An adjustable pediatric general surgery anal dilator includes a tube body, the tube body is inserted inside the connecting cylinder, and one end of the tube body is movably connected with a plug rod. A flow rate valve, a disc and a pushing airbag are arranged inside the tube body. The disc is located between the flow rate valve and the pushing airbag, and a through hole is formed in the center of the side wall of the disc. One end of the pushing airbag is provided with a second air tube, and the second air tube passes through the disc through the through hole and is communicated with the flow rate valve. A spring is arranged between the flow rate valve and the disc, and the spring is used to control the distance between the pushing airbag and the flow rate valve. Sliding holes are symmetrically formed on both sides of the surface of the tube body, a connecting rod is slidably arranged inside the sliding holes, and both ends of the connecting rod are fixedly connected with the side wall of the disc and the inner wall of the connecting cylinder respectively. The other end of the flow rate valve is communicated with a rubber ball through a first air tube and an air valve.

[0006] Preferably, an elastic positioning plate is fixedly installed on one side of the inner wall of the sliding hole away from the plug rod. The elastic positioning plate is inclined, and the elastic positioning plate is used to control the sliding range of the connecting rod.

[0007] Preferably, a soft rod is arranged at the bottom of the connecting cylinder, and the other end of the soft rod is fixedly connected to the top of a fixed clip.

[0008] Preferably, a safety valve is also fixedly installed inside the tube body. The safety valve is located between the pushing airbag and the plug rod, and the safety valve is used to control the communication between the pushing airbag and the plug rod. An expansion airbag is fixedly wrapped around the outer periphery of the surface of the plug rod, and air holes are symmetrically arranged at equal intervals on the surface of the plug rod.

[0009] Preferably, an auxiliary hole is formed on the surface of the tube body. The auxiliary hole is located above the safety valve. The adjusting end of the safety valve extends to the outside of the tube body through the auxiliary hole, and sealing rings are arranged at both ends of the safety valve. The sealing rings are used to increase the sealing effect.

[0010] Preferably, the plug rod is threadedly connected with the tube body, and the plug rod is of a cross-shaped structure. The expansion airbag and the air holes are both arranged on the part with a shorter diameter of the plug rod, and the end of the plug rod is of a circular chamfer structure.

[0011] Preferably, a detection groove is formed inside the tube body. The detection groove is located between the safety valve and the plug rod, and an installation hole is formed on the side wall of the detection groove. A pressure detector is hermetically installed inside the installation hole.

[0012] Preferably, both the installation hole and the pressure detector are inclined, and the inclined directions of the installation hole and the pressure detector are away from the plug rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) The present invention is provided with a rubber ball, a flow rate valve, a pushing airbag, etc. The child lies on the bed in a side-lying position, and the medical staff continuously presses the rubber ball, so that the outside air passes through the air valve and the first trachea and then passes through the flow rate valve to adjust the flow rate, so that the air enters the inside of the pushing airbag uniformly. As the air is injected, the pushing airbag gradually expands, and then squeezes the disc and the spring, so that the tube drives the insertion rod to move forward uniformly, forcing the insertion rod to be inserted into the anus of the child uniformly, reducing the discomfort of the child and reducing the resistance of the child to anal dilation.

[0015] (2) The present invention is provided with a spring, a safety valve, an expansion airbag, etc. During insertion, since the pushing airbag needs to squeeze the spring to expand, a relatively large air pressure is required inside the pushing airbag to drive the tube to move. At this time, by gradually reducing the set value of the safety valve, the high-pressure gas inside the pushing airbag enters the inside of the insertion rod through the safety valve and enters the inside of the expansion airbag on the outer wall of the insertion rod through the air holes, causing the volume of the expansion airbag to gradually expand, thereby increasing the diameter of the anal dilator without the need to replace anal dilators of different diameters multiple times, which is convenient to use.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 - 5 As shown, the present invention provides the following technical solution: An adjustable pediatric general surgery anal dilator includes a tube body 10. The tube body 10 is inserted into the inside of a connecting cylinder 13, and one end of the tube body 10 is movably connected to an insertion rod 9. A flow rate valve 3, a disc 19, and a pushing airbag 12 are arranged inside the tube body 10. The disc 19 is located between the flow rate valve 3 and the pushing airbag 12, and a perforation 18 is provided at the center of the side wall of the disc 19. One end of the pushing airbag 12 is provided with a second air tube 20. The second air tube 20 passes through the disc 19 through the perforation 18 and is communicated with the flow rate valve 3. A spring 15 is arranged between the flow rate valve 3 and the disc 19. The spring 15 is used to control the distance between the pushing airbag 12 and the flow rate valve 3. Sliding holes 4 are symmetrically opened on both sides of the surface of the tube body 10. A connecting rod 16 is slidably arranged inside the sliding holes 4. Both ends of the connecting rod 16 are fixedly connected to the side wall of the disc 19 and the inner wall of the connecting cylinder 13 respectively. The other end of the flow rate valve 3 is communicated with a rubber ball 1 through a first air tube 14 and an air valve 2. A soft rod 21 is arranged at the bottom of the connecting cylinder 13, and the other end of the soft rod 21 is fixedly connected to the top of a fixing clip 22.

[0025] Through the above technical solution, the child lies on the bed in a side-lying position. The medical staff clamps and fixes the device to the edge of the bed through the fixing clip 22, and by pushing the tube body 10, forces the soft rod 21 to deform, thereby adjusting the position of the tube body 10 to align the insertion rod 9 with the child's anus. Subsequently, the medical staff continuously presses the rubber ball 1, so that the outside air enters the inside of the pushing airbag 12 through the air valve 2, the first air tube 14, and the second air tube 20. The flow rate of the gas is adjusted through the flow rate valve 3, so that the air enters the inside of the pushing airbag 12 at a uniform speed, ensuring that the volume of the pushing airbag 12 expands uniformly. As the air is injected, the pushing airbag 12 gradually expands, thereby squeezing the disc 19 and the spring 15, gradually reducing the distance between the disc 19 and the flow rate valve 3. Since the position of the connecting cylinder 13 is fixed by the fixing clip 22 and cannot move, the tube body 10 slides inside the connecting cylinder 13, thereby driving the insertion rod 9 to move forward at a uniform speed, forcing the insertion rod 9 to be inserted into the child's anus at a uniform speed, and completing the uniform pushing-in.

[0026] During recycling, it is only necessary to adjust the air valve 2 so that the gas inside the push airbag 12 is discharged outward. At this time, the volume of the push airbag 12 gradually decreases. Under the action of the elastic force of the spring 15 itself, the distance between the disc 19 and the flow rate valve 3 is increased, thereby pushing the tube body 10 to slide in the opposite direction inside the connecting tube 13. The flow rate valve 3 is used to control the air flow speed, so that the insertion rod 9 is taken out from the child's anus at a uniform speed, thereby reducing the child's discomfort and reducing the child's resistance to anal dilation.

[0027] Furthermore, a safety valve 11 is fixedly installed inside the tube body 10. The safety valve 11 is located between the pushing airbag 12 and the insertion rod 9, and the safety valve 11 is used to control the communication between the pushing airbag 12 and the insertion rod 9. An expansion airbag 8 is fixedly wrapped around the outer surface of the insertion rod 9, and air holes 7 are symmetrically provided on the surface of the insertion rod 9 at equal intervals. An auxiliary hole 24 is provided on the surface of the tube body 10, and the auxiliary hole 24 is located above the safety valve 11. The regulating end of the safety valve 11 extends to the outside of the tube body 10 through the auxiliary hole 24, and sealing rings 25 are provided at both ends of the safety valve 11. The sealing ring 25 is used to increase the sealing effect. An elastic positioning plate 17 is fixedly installed on the side of the inner wall of the sliding hole 4 away from the insertion rod 9. The elastic positioning plate 17 is tilted, and the elastic positioning plate 17 is used to control the sliding range of the connecting rod 16.

[0028] Please refer to Figures 1 - 4 and Figure 6 When the tube body 10 slides inside the connecting tube 13, the connecting rod 16 also slides inside the sliding hole 4 synchronously, and after squeezing the elastic positioning plate 17 to deform it, it continues to slide until the connecting rod 16 is out of contact with the elastic positioning plate 17. The elastic positioning plate 17 is immediately reset under the action of its own elastic force, and the connecting rod 16 is blocked and fixed by the elastic positioning plate 17, so that the insertion rod 9 cannot continue to move backward. Moreover, since the pushing airbag 12 needs to squeeze the spring 15 to expand, a larger air pressure is required inside the pushing airbag 12 to push the tube body 10 to move. At this time, by gradually reducing the set value of the safety valve 11, the high-pressure gas inside the pushing airbag 12 enters the interior of the insertion rod 9 through the safety valve 11, and enters the expansion airbag 8 on the outer wall of the insertion rod 9 through the air hole 7, causing the volume of the expansion airbag 8 to gradually expand, thereby increasing the diameter of the anal dilator rod, and there is no need to replace anal dilators of different diameters multiple times, which prevents the problem of taking the wrong one when replacing, and reduces the number of equipment for subsequent cleaning.

[0029] In addition, the installed sealing ring 25 fills the gap between the safety valve 11 and the inner wall of the pipe body 10, thereby increasing the sealing effect and preventing the problem of air leakage.

[0030] Furthermore, the insertion rod 9 is threadedly connected to the tube body 10, and the insertion rod 9 has a cross-shaped structure. The expansion airbag 8 and the air hole 7 are both arranged on the part of the insertion rod 9 with a shorter diameter, and the end of the insertion rod 9 has a circular chamfer structure.

[0031] Please refer to Figures 1 - 2 , since the insertion rod 9 is threadedly connected to the tube body 10, it not only improves the sealing effect, but also can be disassembled and thoroughly cleaned by rotating the insertion rod 9 after use, which is convenient for use. Moreover, the design of the circular chamfer makes the end of the insertion rod 9 more smooth when inserted, further reducing the discomfort of children and ensuring that children can cooperate well with medical staff for operation.

[0032] Furthermore, a detection groove 23 is formed inside the tube body 10. The detection groove 23 is located between the safety valve 11 and the insertion rod 9. An installation hole 6 is formed on the side wall of the detection groove 23. A pressure detector 5 is hermetically installed inside the installation hole 6. The installation hole 6 and the pressure detector 5 are both inclined, and the inclination directions of the installation hole 6 and the pressure detector 5 are away from the insertion rod 9.

[0033] Please refer to Figures 1 - 3 , since the detection groove 23 is arranged between the safety valve 11 and the insertion rod 9, after the high-pressure gas passes through the safety valve 11, it gradually fills the inside of the detection groove 23, the insertion rod 9 and the expansion airbag 8, causing the extrusion force generated by the expansion airbag 8 on the anal muscles to gradually increase. However, due to the slow adaptation time of the anal muscles, after the gas is injected into the expansion airbag 8, the volume of the expansion airbag 8 will not immediately increase due to the extrusion of the muscles, resulting in a relatively high pressure inside the expansion airbag 8 at the beginning. As time goes by, the anus gradually adapts to the expansion airbag 8 and the anal diameter gradually increases, causing the volume of the expansion airbag 8 to gradually increase and its internal pressure to gradually decrease. Medical staff only need to observe the reading of the pressure detector 5. When the reading of the pressure detector 5 tends to be stable, the set value of the safety valve 11 can be further reduced to gradually increase the diameter of the insertion rod 9. The pressure detector 5 is used to detect the air pressure values inside the detection groove 23, the insertion rod 9 and the expansion airbag 8 in real time, and with the feedback of children, it helps medical staff accurately understand the actual situation and continue to increase the diameter of the insertion rod 9 at an appropriate time to prevent problems such as anal laceration, tearing and long treatment time caused by replacing the anal dilator too early or too late.

[0034] Moreover, since the installation hole 6 and the pressure detector 5 are both inclined, the pressure detector 5 is gradually away from the child's skin, which not only facilitates the reading of medical staff, but also reduces the possibility of contact between the pressure detector 5 and the child's skin, making it convenient for later cleaning.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
