Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Embodiment one:
Present embodiments provide a kind of catheter assembly, it comprises urethral catheterization flexible pipe 1, urethral probe 2 and metal urethral catheter 3.
As shown in Figure 1, one end of urethral catheterization flexible pipe 1 is closed, other end opening.The first urethral catheterization hole 11 is offered at the blind end of urethral catheterization flexible pipe 1.Urethral catheterization flexible pipe 1 is made up of more soft material, as silica gel, rubber etc., can alleviate the discomfort of patient when ensureing that it contacts with the urethra of patient as far as possible.Internal diameter and the length of urethral catheterization flexible pipe 1 can be different according to the different set of patient size.In the present embodiment, the internal diameter of urethral catheterization flexible pipe 1 is 6mm, and length is 28cm.
As shown in Figure 2, the length of urethral probe 2 is greater than the length of urethral catheterization flexible pipe 1, and it can penetrate in urethral catheterization flexible pipe 1.One end of urethral probe 2 has ball head structure 21, and the other end has clamping part 22, and clamping part 22, for clamping urethral catheterization flexible pipe 1, prevents from inserting slippage in the process of patient's urethra at urethral catheterization flexible pipe 1.
As a kind of optimal way, urethral probe 2 is bent to form by steel wire.The curved button 222 that the free end that clamping part 22 comprises loop configuration 221 that per urethram probe end is bent to form and loop configuration 221 is bent to form.When not in use, curved button 222 can be buckled in urethral probe 2.During use, curved button 222 is untied, grips loop configuration 221, to coordinate with loop configuration 221 to be formed urethral catheterization flexible pipe 1 with curved button 222 and clamp.
As shown in Figure 3, the length of metal urethral catheter 3 is greater than the length of urethral catheterization flexible pipe 1, and it can penetrate in urethral catheterization flexible pipe 1.One end of metal urethral catheter 3 is closed, and other end opening, offers the second urethral catheterization hole 31 corresponding with the first urethral catheterization hole 11 at the blind end of metal urethral catheter 3, be removably connected with irrigator 5 at the opening of metal urethral catheter 3.
As a kind of optimal way, metal urethral catheter 3 is connected with irrigator 5 by connecting hose 4.One end metal urethral catheter 3 connecting irrigator 5 superposes successively and is provided with multiple frustum of a cone 32, and the direction in the diametrically second urethral catheterization hole 31 of the frustum of a cone 32 increases gradually.This structure facilitates penetrating of connecting hose 4, and effectively can prevent the slippage of connecting hose 4.
In the present embodiment, as a kind of optimal way, irrigator 5 adopts acrylic sphere.
During use, first urethral probe 2 is penetrated in urethral catheterization flexible pipe 1 by one end of ball head structure 21, because urethral probe 2 has certain rigidity, can under the effect of urethral probe 2, urethral catheterization flexible pipe 1 be penetrated in the urethra of patient, urethral catheterization can be carried out after urethral probe 2 being pulled out, owing to being provided with clamping part 22 in the end of urethral probe 2, clamp urethral catheterization flexible pipe 1 by clamping part 22, prevent its slippage.In addition, because ball head structure 21 end is circular arc, the injury to patient's urethra is reduced.
When needs rinse bladder, can metal urethral catheter 3 be penetrated in urethral catheterization flexible pipe 1, be rinsed by the irrigator 5 pairs of bladders being connected to metal urethral catheter 3 opening, operation and easy to use, farthest reduce the misery of patient.
Wherein, the set-up mode in the first urethral catheterization hole 11 and the second urethral catheterization hole 31 is not limit, and can be set to one, may also be set to multiple, such as, the sidewall of the blind end of urethral catheterization flexible pipe 1 along the circumferential direction has multiple first urethral catheterization hole 31, urethral catheterization hole 11, second is corresponding with the first urethral catheterization hole 11 to be arranged.The aperture in the first urethral catheterization hole 11 and the second urethral catheterization hole 31 is not limit, and can carry out setting different sizes according to the difference of patient, its preferred scope is 1 to 3mm.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to this utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
