The mode that this scheme was stored through carrying out the anesthetic, at the in-process of patient catheterization, implements surface anesthesia to the patient, makes patient can comfortably tolerate the catheter, does not lead to the vexation, frequent urine of appearing and feels etc to prevent the used repeatedly of catheter, cause the cross infection between patient and the patient, avoid setting up complicated pipeline in the catheter simultaneously, increase manufacturing cost.

Description

Novel disposable catheter with anesthesia function

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a novel disposable catheter with an anesthesia function.

Background

At present, in clinical practice, patients with urine retention, patients who need long-time operation, unconscious patients and other patients who need urethral catheterization or catheter indwelling are difficult to tolerate because of stimulation to urethral mucosa and bladder mucosa after the catheter is pulled out, and the rehabilitation of physical and mental health and diseases of the patients is extremely unfavorable.

For example, chinese patent discloses a balloon catheter with surface anesthesia function (patent number: CN 99254909.4), which comprises a catheter pipeline, a catheter hole, an inflation pipeline, an inflation cuff and an inflation pipe tail end connector. Said patent is characterized by that it can make the urethral mucosa and bladder mucosa implement surface anesthesia, so that the patient can comfortably tolerate the catheter.

However, the above urinary catheter needs to be repeatedly used, which results in that medical care personnel need to repeatedly clean the urinary catheter, and meanwhile, due to the arrangement of the micro-pipeline in the urinary catheter, the interior of the urinary catheter is difficult to clean, bacteria are easily remained, which results in cross infection between patients, and a great potential safety hazard is accompanied in the using process.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a novel disposable catheter with anesthesia function, which solves the problem of the prior art.

(II) technical scheme

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a novel disposable catheter of area anesthesia function, includes pipe shaft, sacculus, protection bag, capsule layer and catheterization subassembly, set up catheterization pipe joint in the pipe shaft, the sacculus is located pipe shaft surface upside, the protection bag is located the sacculus outside, the protection bag with be equipped with the storage chamber between the sacculus, it has powdered anesthetic to store the intracavity packing, the capsule layer is located in the protection bag, the capsule layer can with the protection bag seals.

Preferably, the capsule layer is composed of gelatin and an enteric coating.

Preferably, an inflation cavity is arranged in the balloon.

Preferably, the lower side of the outer surface of the urethral catheterization pipeline joint is connected with a water injection joint, and an injection pipeline on the inner side of the water injection joint is communicated with the expansion cavity.

Preferably, a urethral catheterization hole is formed in the catheter body and communicated with the urethral catheterization pipeline joint.

(III) advantageous effects

The utility model provides a novel disposable catheter with anesthesia function. The method has the following beneficial effects:

1. this scheme is through carrying out the mode of storing anesthetic, at the in-process of patient's catheterization, implements surface anesthesia to the patient, makes patient can comfortably tolerate the catheter, does not lead to the appearance vexed, frequent urine is felt etc. to prevent the repeated use of catheter, cause the cross infection between patient and the patient, avoid setting up complicated pipeline in the catheter simultaneously, increase manufacturing cost.

Drawings

Fig. 1 is a schematic view of the structure of the present invention;

fig. 2 is a sectional view of the present invention;

fig. 3 is an enlarged schematic view of the structure at a in fig. 2.

In the figure: 11. a tube body; 12. a urinary catheter joint; 13. a water injection joint; 14. a balloon; 15. an expansion chamber; 16. a protective bag; 17. a capsule layer; 18. a storage chamber; 20. a urethral catheterization hole.

Detailed Description

The embodiment of the utility model provides a novel disposable catheter of area anesthesia function, as shown in fig. 1-3, including shaft 11, sacculus 14, protection bag 16, capsule layer 17 and catheterization subassembly, set up catheterization pipe joint 12 in the

shaft

11, 11 surface upsides of shaft are located to sacculus 14, as shown in fig. 3, the protection bag 16 is located the sacculus 14 outside, is equipped with between protection bag 16 and the sacculus 14 and stores the chamber 18, stores the intracavity 18 intussuseption and is filled with powdered anesthetic, and in capsule layer 17 located protection bag 16, capsule layer 17 can seal protection bag 16.

The capsule layer 17 is composed of gelatin and enteric coating, and the capsule layer 17 and the water in the urine of the patient can be slowly dissolved.

An inflation lumen 15 is provided within the balloon 14.

As shown in FIG. 2, a water injection joint 13 is connected to the lower side of the outer surface of the catheter joint 12, and the injection pipe inside the water injection joint 13 is communicated with the expansion chamber 15.

The catheter body 11 is internally provided with a urethral catheterization hole 20, and the urethral catheterization hole 20 is communicated with the urethral catheterization pipeline joint 12.

Medical personnel injects 10mL liquid into inflation chamber 15 through water injection joint 13, and then make sacculus 14 inflation, this moment, sacculus 14 makes the urine flow out through catheterization hole 20 and catheterization pipeline joint 12 with urethral blockage, this moment, medical personnel through catheterization pipeline joint 12 bottom carry on the refluence can, meanwhile, sacculus 14 drives protection bag 16 and expands in step, protection bag 16 extrudes with patient's urethra lateral wall mutually, and then make the interior pressure increase of storage chamber 18, at this moment, the inside moisture with in the patient's urine of capsule layer 17 dissolves mutually, it breaks to lead to pressure to increase to make capsule layer 17 after the threshold value, the powdered anesthetic of storage chamber 18 inboard carries out the anesthesia to the patient, be convenient for medical personnel take out body of pipe 11 after accomplishing the operation, reduce the misery that the mucous membrane damage that causes the patient owing to pull out behind body of pipe 11.
