Technical Field

The invention relates to the technical field of instruments for inputting media into or onto a human body, in particular to an analgesic urinary catheter.

Background

A catheter is a tube made of natural rubber, silicone or polyvinyl chloride for guiding urine out of the body from the bladder. However, since the catheter belongs to clinical invasive medical materials, when the catheter is inserted into the bladder through the urethra, pain of a patient is obvious, and discomfort at the insertion position can cause stronger stimulation to the patient, no good solution exists in the prior art to reduce the discomfort at the insertion position of the patient.

Disclosure of Invention

The inventors found through research that: according to the structural characteristics of the existing catheter and the contact position after the catheter is inserted, if the slow-release cream can be synchronously smeared when the catheter is inserted, the uncomfortable feeling of a patient can be obviously reduced, but because the space of the catheter is limited, if the catheter body can be structurally optimized to realize the scheme, the technical breakthrough in the field can be brought.

The invention aims to provide an analgesic catheter, which solves the technical problem that the prior art cannot provide a catheter capable of relieving uncomfortable feeling of a patient.

According to one aspect of the present invention, there is provided an analgesic urinary catheter comprising a catheter body having a connecting section at one end and a guide section at the other end; the connecting section is detachably connected with a flexible pressing piece; the guide section is of a composite structure and is divided into an outer layer and an inner layer, a plurality of guide holes are formed in the outer layer at intervals, and slow-release cream for relieving pain is poured between the outer layer and the inner layer.

In some embodiments, the slow release cream is a lidocaine cream.

In some embodiments, an auxiliary conduit is also provided on the tube.

In some embodiments, the auxiliary conduit end is provided with a lubricant filled section.

In some embodiments, the segment end of the guide segment is removably attached with a balloon.

In some embodiments, the flexible press is a pressure bladder.

Compared with the prior art, the invention has the following advantages:

according to the invention, the body of the catheter is provided with the plurality of diversion openings for guiding the slow-release cream to flow, so that the effective guiding of the slow-release cream, namely the lidocaine cream, is realized, and the discomfort of a patient is directly relieved; meanwhile, the flexible pressing piece is arranged at the end part of the tube body to realize the flow assistance of the slow-release cream, so that the smearing proportion of the slow-release cream at the contact position with the urinary catheter is ensured.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

The present embodiment provides an analgesic urinary catheter which is already in a test use stage, and is described below with reference to fig. 1 to 4, and meanwhile, the present invention overcomes technical obstacles in the field, and alleviates discomfort of a patient while achieving normal catheterization.

Example 1

This embodiment provides an analgesia catheter, including body 3, body 3 one end is provided with linkage segment 2, and the other end is provided with guide section 5, and flexible push piece 1 is detachably connected on the linkage segment 2, and guide section 5 is composite construction, and composite construction divide into outer 52 and inlayer 51, and the interval is equipped with a plurality of water conservancy diversion holes 521 on the outer 52, and it has the slowly-releasing cream that is used for pain to alleviate to pour into between outer 52 and the inlayer 51, and this embodiment is preferably slowly-releasing cream: lidocaine cream.

Specifically, the guiding section 5 is inserted into the urinary catheter during operation, the flexible pressing member 1 on the connecting section 2 is pressed by a medical staff after insertion, and the pressure is increased to push the slow-release cream poured between the outer layer 52 and the inner layer 51 to flow, so that the slow-release cream flows out through the guiding hole 521 and is laid in the urinary catheter contact area, and discomfort of a patient is relieved. It should be noted that, the guiding section 5 of this embodiment adopts a composite structure, so as to better attach to the catheter body for setting. The number of the flow guide holes 521 in this embodiment may be designed according to the insertion length of the urinary catheter of the patient, and is not limited.
