Example 1

Referring to fig. 1 and 2, the present utility model provides the following technical solutions: a novel urinary catheter is suitable for a single person to rapidly perform sterile water injection operation.

Specifically, as shown in fig. 1 and 2, it includes: comprises a catheter body 1 and a water sac assembly 2 for fixing the catheter body 1; the water sac assembly 2 comprises a first water sac 21 fixed on the outer side wall of one end part of the catheter body 1 and a water injection piece 23 connected with the first water sac 21 through a water guide pipe body 22; one end of the water guide pipe body 22 is embedded into the catheter body 1, and the other end of the water guide pipe body penetrates out of the side wall of the catheter body 1. The water sac assembly 2 can stably fix one end of the catheter body 1 inserted into a human body, so that the inserted end of the catheter body 1 slides out when a medical staff performs catheterization, repeated catheterization operation is avoided, time is saved, and discomfort of a patient is relieved.

In this embodiment, the diameter of the catheter body 1 is much larger than the diameter of the water guiding tube body 22; the part of the water guide pipe body 22 penetrating out of the catheter body 1 is sealed by a sealing ring, so that liquid leakage is avoided.

Specifically, as shown in fig. 1 and 2, the water injection member 23 includes a second capsule 231 and a plug 232 inserted into the lumen of the water guiding tube 22; the second bladder 231 is connected to the plug 232 via a short tube 3. The first water bag 21 for fixing the catheter body 1 can be filled with water through the water filling piece 23, so that the first water bag 21 is inflated, and the fixing effect on the catheter body 1 is realized; the second bladder 231 can be communicated with the water guide pipe body 22 through the short pipe 3; the plug body 232 facilitates the sealing connection of the short pipe 3 with the water guide pipe body 22.

In this embodiment, the second bag 231 may store water first and then insert into the water guide pipe body 22 through the short pipe 3 to perform aseptic extrusion water injection operation on the first water bag 21, after extrusion water injection is completed, the second bag 231 after water injection is completed may be clamped by a spring clip, and after catheterization is completed, the spring clip is removed to suck out the aseptic water in the first water bag 21, so as to facilitate the removal of the catheter body 1; the second capsule 231 is made of a material having shape reducing ability.

Specifically, as shown in fig. 1 and 2, the portion of the second capsule 231 that is embedded in the short tube 3 is provided with an extension 4; the plug body 232 is provided with a jack 5 into which the extension portion 4 is inserted. The sterile water previously reserved for the second bladder 231 can be injected into the first water bladder 21 by squeezing by providing the extension 4.

Specifically, as shown in fig. 1 and 2, the length of the extension portion 4 is longer than the length of the plug body 232. By setting the length of the extension portion 4 longer than the length of the plug 232, when the sterile water is injected, the sterile water is not easy to reverse permeate back to the second bag 231 after being injected into the water pouring pipeline, and the operation pressure of a single person is reduced.

In this embodiment, the pipe diameter of the extension portion 4 is far smaller than that of the second capsule 231, so as to avoid the sterile water stored in advance in the second capsule 231 from spilling out.

Specifically, as shown in fig. 1 and 2, the extension portion 4 is a rigid tube body; the second bladder 231 is provided with an opening communicating with the extension 4. By arranging the hard tube body, the telescopic part is convenient to penetrate out of the plug body 232; by providing the opening, the second bladder 231 can be communicated with the water guide tube 22.

In this embodiment, the extension portion 4 may be a hard tube made of PVC.

In particular, as shown in fig. 1 and 2, the short tube 3 is a flexible hose. By arranging the flexible hose, the special situation that the sterile water is not discharged cleanly when the first water bag 21 discharges the sterile water can be conveniently dealt with; the flexible hose can be directly cut off, and a syringe or the like can be inserted into the plug 232 to forcefully suck out the residual water in the first water bladder 21.

In this embodiment, the short tube 3 may be a silicone hose.

In particular, as shown in fig. 1 and 2, the side tube wall of the catheter body 1 is provided with a tube connector 6 communicating with the catheter body 1. By arranging the catheter body joint 6, a catheter flushing pipeline or a drug delivery pipeline can be connected, so that the diversity of catheter functions is increased.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
