In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 4, the auxiliary catheter insertion device of the present invention includes an inner core tube 10 and an outer sheath tube 20 sleeved on the inner core tube 10, wherein a gap is formed between the inner core tube 10 and the outer sheath tube 20, and the gap facilitates the subsequent extraction of the inner core tube 10 from the outer sheath tube 20;
a through drainage channel is arranged in the middle of the inner core tube 10, the drainage channel is arranged along the axial direction of the inner core tube 10, one end of the inner core tube 10 is bent to form a bending part 11, the bending part 11 is used for enabling the inner core tube 10 to conform to the anatomy of urethra and move, the stability of the inner core tube 10 in the insertion process is improved, the other end of the inner core tube 10 is connected with a urine storage pot 12, the urine storage pot 12 is communicated with the drainage channel, when the bending part 11 of the inner core tube 10 reaches the bladder, urine in the bladder flows into the urine storage pot 12 through the drainage channel, the installation of the outer sheath tube 20 is indicated to be in place, and the inner core tube 10 can be drawn out and replaced by a urinary catheter;
Furthermore, the two opposite sides of the external sheath 20 are provided with holding assemblies 30, each holding assembly 30 includes a pressing piece 33, a clamping arm 31 and a holding ring 32, the clamping arm 31 is disposed on the external sheath 20 in a penetrating manner, one end of the clamping arm 31 is located outside the external sheath 20, the other end of the clamping arm 31 is located inside the external sheath 20, the pressing piece 33 is connected to one end of the clamping arm 31 located inside the external sheath 20, and the holding ring 32 is connected to one end of the clamping arm 31 located outside the external sheath 20.
In practical applications, since the inner core tube 10 and the outer sheath tube 20 are in clearance fit, when a medical worker inserts the inner core tube 10 into a urethra, there may be axial movement between the inner core tube 10 and the outer sheath tube 20, which may interfere with the installation state of the outer sheath tube 20 in the urethra, and therefore, in this embodiment, the medical worker can operate the holding ring 32 during the process of inserting the inner core tube 10, so that the pressing sheet 33 can hold the tube wall of the inner core tube 10, and ensure that the relative position between the inner core tube 10 and the outer sheath tube 20 does not change during the process of inserting, thereby improving the installation effect of the outer sheath tube 20 in the urethra.
Further, the pressing pieces 33 are arc-shaped structures which are attached to the surface of the inner core tube 10, and it can be understood that the pressing pieces 33 can be tightly attached to the outer surface of the inner core tube 10 through the arc-shaped structural design, so that the stability of the two pressing pieces 33 in the clamping process is improved.
Specifically, an external thread 51 is arranged at one end of the urinal 12 facing the inner core tube 10, an internal thread 52 adapted to the external thread 51 is arranged on the inner wall of the inner core tube 10, and the inner core tube 10 and the urinal 12 can be detachably connected through thread fit. The inner core tube 10 is made of a metal material, specifically martensite stainless steel, and can be repeatedly used after high-temperature sterilization, and the urine storage pot 12 and the outer sheath tube 20 are disposable products made of plastic materials, and can be detached from the inner core tube 10 and discarded after use.
Further, the outer surface of the outer sheath tube 20 is provided with a hydrophilic coating. Specifically, the hydrophilic coating is a coating of a hydrophilic polymer of polyethylene glycol or polyvinylpyrrolidone. When the sheath tube is used, the sheath tube 20 is firstly put into water for soaking for a plurality of minutes, the hydrophilic coating absorbs water to increase the lubrication of the sheath tube, the friction between the inner core tube 10 and the urethra in the process of being inserted into the urethra is reduced, and the injury of the urethra and the pain of a patient are relieved.
Further, the pipe diameter of the bending part 11 gradually decreases towards the direction away from the urinal 12 to form a conical structure. By designing the bending part 11 to be pointed, the inner core tube 10 can be conveniently inserted into the bladder, and the problem that the insertion position needs to be adjusted repeatedly to cause discomfort of a patient due to the fact that the urethra is blocked by the hyperplastic prostate to block the insertion of the inner core tube 10 is avoided. Further, the ends of the curved portion 11 are provided with edge rounding, it being understood that the rounded design results in the curved portion 11 mitigating damage to the prostate and urethra during insertion.
In summary, in the auxiliary urinary catheter insertion device according to the above-mentioned embodiment of the present invention, the holding ring 32 is clamped to stably insert the end of the inner core tube 10 with the bending portion 11 into the urethra along the urethral orifice, after observing that urine flows into the urinal 12 through the drainage channel, it is proved that the head end of the outer sheath tube 20 reaches the bladder, at this time, the inner core tube 10 is pulled out, the outer sheath tube 20 is retained in the urethra to support the urethra, so that the urinary catheter can be easily inserted, after the urinary catheter is successfully placed, the outer sheath tube 20 is torn along the easy-to-tear line 40 and then taken out, the operation process is simple and efficient, the injury to the patient is minimal, and the technical problems of high treatment difficulty and great injury when the urinary catheter is placed into the patient in the prior art are solved.
