Examples

Referring to fig. 1-3, the embodiment provides a flaring catheter with easy drainage, which includes a catheter tube 1, wherein the tube 1 includes a fixed end 12 and a flared end 11. The tube body 1 is provided with an air bag 2, and the flaring end 11 and the fixed end 12 are respectively positioned at two sides of the air bag 2. The fixed end 12 and the flared end 11 are practically integrated, both belonging to a part of the tube body 1, but forming a boundary line based on the balloon 2, the materials of both being made of different structures. The fixed end 12 has a vertical outer diameter, while the flared end 11 has a diameter greater than that of the fixed end 12, with an outer diameter that tends to expand with respect to said fixed end 12. A sheathing guide wire 3, wherein the sheathing guide wire 3 is fixed at the opening part of the flared end 11 and comprises a lantern ring 31 and a traction guide wire 32; the opening edge of the flared end 11 is embedded into the lantern ring 31, and the traction guide wire 32 is fixedly connected with the lantern ring 31; the bundle guide wire 3 serves to form a restriction to the opening portion of the flared end 11. Thus, by the restraint of the sleeve guide wire 3, the diameter of the flared end 11 is the same as that of the fixed end 12 in the restraining stage, so that the insertion of the patient can be more conveniently carried out. After inserting the completion, take out to restraint seal wire 3 for flared end 11 reconversion forms bigger drainage mouth in the bladder, and the patient's drainage that makes the deposit in the bladder many is more smooth and easy.

In order to achieve the above design, the outer edge of the flared end 11 is formed by enclosing a plurality of construction lines; the structural line gradually inclines towards one side far away from the central axis of the pipe body 1 along the extending direction of the pipe body 1. The outer edge is not only a certain side or a certain part of the edge, but the whole flared end 11, and is all the outer surface edge of the cylinder. The starting point of the construction line is connected with one surface of the flared end 11 close to one side of the airbag 2 or the outer edge of the surface; the end of the construction line is connected to one face or the outer edge of the opening of the flared end 11. Thus, the flared end 11 is flared in its overall form, with an opening having a diameter greater than the diameter of the fixed end 12, and the diameter of the intersection with the balloon 2 equal to the diameter of the fixed end 12, allowing easier drainage during drainage. Meanwhile, the construction line is gradually inclined towards one side far away from the central axis of the pipe body 1, and the inclined slope is gradually increased. That is, the opening diameter of the flared end 11 gradually increases as the flared end 11 extends. The specific style and size of the embodiment are not limited, and the specification of the flared end 11 can be designed according to the actual needs and production requirements.

In order to make flaring easy and not increase pain of a patient when inserting a catheter, the sleeve bundle guide wire 3 is movably connected with the opening part of the flaring end 11, and the opening part of the flaring end 11 is in embedded clamping connection with the sleeve ring 31. In the embodiment, the clamping is that the collar 31 is in a semi-surrounding shape and annularly covers the outer edge of the opening part of the flared end 11; the outer rim of flared end 11 is embedded inside collar 31. The collar 31 and the pull guide wire 32 are fixedly connected, and may be produced integrally during production, or may be connected in any way capable of interacting with each other. Thus, when the traction guide wire 32 is displaced, the lantern ring 31 is driven to displace together, and as the lantern ring 31 is supported by a flexible material, any material which can keep a certain shape and can be elastically deformed, such as rubber, silica gel and the like, can be used. The lantern ring 31 is deformed by traction force, so that the opening part of the flared end 11 is separated from the restraint of the lantern ring 31, the original shape is recovered, and the expansion of the drainage opening is completed.

In this embodiment, the diameter of the collar 31 is the same as the diameter of the fixed end 12; the diameter of the opening of the flared end 11 is greater than the diameter of the collar 31. Thus, the flared end 11 is constrained to the same diameter as the fixed end 12, which may ease patient pain during catheter insertion. The flared end 11, however, acts to enlarge the drainage contact area of the catheter inside the bladder, so its diameter is also larger than the diameter of the collar 31. The diameter of flared end 11 is reduced by the restraint of collar 31.

Furthermore, the end of the fixed end 12 away from the airbag 2 further comprises a three-cavity pipeline 4, and the three-cavity pipeline 4 comprises a water injection pipeline 41, a drug pipeline 43 and a liquid outlet pipeline 42; the water injection pipeline 41 is communicated with the air bag 2, and the sheathing guide wire 3 extends into the flared end 11 through the liquid outlet pipeline 42. After the catheter is inserted, the air bag 2 is expanded through the water injection pipeline 41, the catheter is limited in the bladder, and the catheter is prevented from falling off after being implanted. The sleeve bundle guide wire 3 is stretched in the tube body 1 through the liquid outlet pipeline 42, placed inside the tube body 1 when being placed, pulled out through the liquid outlet after being placed, and then connected with the urine bag through the liquid outlet to form a stable catheterization system. In order to reduce the discomfort of the patient, the catheter of the embodiment is integrally made of tpe materials. Compared with rubber or silica gel materials, the rubber or silica gel material can be kept for a longer time, and meanwhile, the discomfort is reduced.

Furthermore, the present embodiment also includes a pressure alarm 5 disposed outside the fixed end 12 of the tube 1, which includes a pressure sensor 51 and an alarm 52, the pressure sensor 51 is electrically connected to the alarm 52, and when a pressure exceeding a predetermined level is sensed, the alarm 52 gives a prompt, so as to provide a better therapeutic effect for patients who lose part of their consciousness or have a poor ability to express discomfort. Different physiological characteristic data are set by medical personnel according to different patient conditions, and timely understanding and alarming can be made through the pressure sensor 51 in the process of intubation or use. Preventing the inflammation of the patient.

The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
